Radiother Oncol 2024; 200:110498. [PMID: 39182582 DOI: 10.1016/j.radonc.2024.110498] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2024] [Revised: 08/17/2024] [Accepted: 08/22/2024] [Indexed: 08/27/2024]
Abstract
BACKGROUND Whether coronary computed-tomography angiography (CCTA) can detect cancer treatment-related impairments of coronary artery and predict major adverse cardiovascular events (MACEs) in lung cancer patients receiving chemotherapy (CHT) or chemoradiotherapy (CRT) is unclear. OBJECTIVES This study aimed to evaluate coronary arteries using CCTA parameters and explore the association of these parameters with MACEs in patients with lung cancer receiving CHT or CRT. MATERIALS AND METHODS This study retrospectively collected data from 697 lung cancer patients who received CHT or CRT and underwent CCTA examination within 2 weeks before or after treatment from June 2013 to May 2019. The patients were divided into CHT and CRT group, and for the control group, the propensity score matching (PSM) was used and 125 participants without carcinoma with a single CCTA examination were included. CCTA parameters, assessed using artificial intelligence software, were compared across different groups (control vs. CHT & CRT; CHT vs. CRT). We analyzed associations between CCTA parameters and MACEs using a Cox-regression model and Kaplan-Meier curves to compare MACE-free survival rates. RESULTS Before CHT or CRT, compared with the control group, in CHT&CRT group we observed higher fat attenuation index (FAI), coronary-artery calcium (CAC) score, CAD-RADS classification, stenosis severity and lower computed-tomography fractional flow reserve (CT-FFR; all P<0.05). After treatment, the CT-FFR decreased and the FAI increased; simultaneously, we observed a lower CT-FFR and higher FAI (all P<0.05) in the CRT than in the CHT group. Among the 146 cases developed MACEs, lower CT-FFR and higher FAI values were found compared with the non-MACE group (all P<0.05), and CT-FFR and FAI before treatment were associated with MACEs. CONCLUSION Cancer treatment-related impairments of coronary arteries could be identified using CT-FFR and FAI. Before treatment, these parameters were associated with MACEs in lung cancer patients receiving CHT or CRT.

Three-dimensional printing for preoperative rehearsal and intraoperative navigation during laparoscopic rectal cancer surgery with left colic artery preservation. World J Gastrointest Surg 2024; 16:3104-3113. [DOI: 10.4240/wjgs.v16.i10.3104] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2024] [Revised: 08/29/2024] [Accepted: 09/12/2024] [Indexed: 09/27/2024] Open
Abstract
BACKGROUND Prior studies have shown that preserving the left colic artery (LCA) during laparoscopic radical resection for rectal cancer (RC) can reduce the occurrence of anastomotic leakage (AL), without compromising oncological outcomes. However, anatomical variations in the branches of the inferior mesenteric artery (IMA) and LCA present significant surgical challenges. In this study, we present our novel three dimensional (3D) printed IMA model designed to facilitate preoperative rehearsal and intraoperative navigation to analyze its impact on surgical safety.
AIM To investigate the effect of 3D IMA models on preserving the LCA during RC surgery.
METHODS We retrospectively collected clinical dates from patients with RC who underwent laparoscopic radical resection from January 2022 to May 2024 at Fuyang People’s Hospital. Patients were divided into the 3D printing and control groups for statistical analysis of perioperative characteristics.
RESULTS The 3D printing observation group comprised of 72 patients, while the control group comprised 68 patients. The operation time (174.5 ± 38.2 minutes vs 198.5 ± 49.6 minutes, P = 0.002), intraoperative blood loss (43.9 ± 31.3 mL vs 58.2 ± 30.8 mL, P = 0.005), duration of hospitalization (13.1 ± 3.1 days vs 15.9 ± 5.6 days, P < 0.001), postoperative recovery time (8.6 ± 2.6 days vs 10.5 ± 4.9 days, P = 0.007), and the postoperative complication rate (P < 0.05) were all significantly lower in the observation group.
CONCLUSION Utilization of a 3D-printed IMA model in laparoscopic radical resection of RC can assist surgeons in understanding the LCA anatomy preoperatively, thereby reducing intraoperative bleeding and shortening operating time, demonstrating better clinical application potential.

Abstract
BACKGROUND Total neoadjuvant therapy has revolutionized the treatment of locally advanced rectal cancer and quickly become the new standard of care. Whether patients from all racial and ethnic groups have had equal access to these potential benefits, however, remains unknown. METHODS We identified all adults diagnosed with locally advanced rectal cancer in California who underwent neoadjuvant chemotherapy and radiation from 2010 to 2020 using the California Cancer Registry. We used logistic regression to estimate the predicted probability of receiving total neoadjuvant therapy as opposed to traditional chemoradiotherapy for each racial and ethnic group and used a time-race interaction to evaluate trends in access to total neoadjuvant therapy over time. We also compared survival by racial and ethnic group and total neoadjuvant therapy status using Kaplan-Meier plots and Cox proportional hazards models. RESULTS In total, 6,856 patients met inclusion criteria. Overall, 36.6% of patients received total neoadjuvant therapy in 2010 compared with 66.3% in 2020. Latino patients were significantly less likely than non-Latino White patients to undergo total neoadjuvant therapy ; however, there was no difference in the rate of growth in total neoadjuvant therapy over time between racial and ethnic groups. Non-Latino Black patients appeared to have lower risk-adjusted survival compared with non-Latino White patients, although not among patients who underwent total neoadjuvant therapy . CONCLUSION Access to total neoadjuvant therapy has increased significantly over time in California with no apparent difference in the rate of growth between racial and ethnic groups. We found no evidence of racial or ethnic disparities in survival among patients treated with total neoadjuvant therapy, suggesting that increasing access to high-quality cancer care may also improve health equity.

Abstract
ASCO Guidelines provide recommendations with comprehensive review and analyses of the relevant literature for each recommendation, following the guideline development process as outlined in the ASCO Guidelines Methodology Manual. ASCO Guidelines follow the ASCO Conflict of Interest Policy for Clinical Practice Guidelines.Clinical Practice Guidelines and other guidance ("Guidance") provided by ASCO is not a comprehensive or definitive guide to treatment options. It is intended for voluntary use by providers and should be used in conjunction with independent professional judgment. Guidance may not be applicable to all patients, interventions, diseases or stages of diseases. Guidance is based on review and analysis of relevant literature, and is not intended as a statement of the standard of care. ASCO does not endorse third-party drugs, devices, services, or therapies and assumes no responsibility for any harm arising from or related to the use of this information. See complete disclaimer in Appendix 1 and 2 (online only) for more.PURPOSETo provide evidence-based guidance for clinicians who treat patients with locally advanced rectal cancer.METHODSA systematic review of the literature published from 2013 to 2023 was conducted to identify relevant systematic reviews, phase II and III randomized controlled trials (RCTs), and observational studies where applicable.RESULTSTwelve RCTs, two systematic reviews, and one nonrandomized study met the inclusion criteria for this systematic review. Expert Panel members used available evidence and informal consensus to develop evidence-based guideline recommendations.RECOMMENDATIONSFollowing assessment with magnetic resonance imaging, for patients with microsatellite stable or proficient mismatch repair locally advanced rectal cancer, total neoadjuvant therapy (TNT; ie chemoradiation [CRT] and chemotherapy) should be offered as initial treatment for patients with tumors located in the lower rectum and/or patients who are at higher risk for local and/or distant metastases. Patients without higher-risk factors may discuss chemotherapy with selective CRT depending on extent of response, TNT, or neoadjuvant long-course CRT or short-course radiation. For patients who are candidates for TNT, the preferred timing for chemotherapy is after radiation, and neoadjuvant long-course CRT is preferred over short-course radiation therapy (RT), however short-course RT may also be a viable treatment option depending on circumstances. Nonoperative management may be discussed as an alternative to total mesorectal excision for patients who have a clinical complete response to neoadjuvant therapy. For patients whose tumors are microsatellite instability-high or mismatch repair deficient, immunotherapy is recommended.Additional information is available at http://www.asco.org/gastrointestinal-cancer-guidelines.

Abstract
BACKGROUND Total neoadjuvant therapy (TNT) has been used for patients with locally advanced rectal cancer. The optimal sequence of chemoradiotherapy (CRT) and chemotherapy (CT) is a matter of debate. METHODS We performed a pooled analysis of the CAO/ARO/AIO-12 and OPRA multicenter, randomized phase 2 trials to identify patient subsets that could benefit from one TNT sequence over the other regarding disease-free survival (DFS). Patients with stage II/III rectal cancer were randomized to CRT (50.4-54 Gy) with either induction (INCT-CRT) or consolidation CT (CRT-CNCT) with fluorouracil, leucovorin, oxaliplatin (CAO/ARO/AIO-12 and OPRA) or capecitabine and oxaliplatin (OPRA) followed by mandatory total mesorectal excision (TME) (CAO/ARO/AIO-12) or selective watch-and-wait surveillance (OPRA). 311 and 324 patients were recruited from June 15, 2015 to January 31, 2018; and from April 12, 2014 to March 30, 2020 in the two trials, respectively. Pretreatment clinical and tumor characteristics included were age, sex, ECOG, cT-category, cN-category, clinical UICC stage, location from anal verge, and tumor grade. FINDINGS In total, 628 eligible patients were included in the pooled analysis (CAO/ARO/AIO-12, n = 304; OPRA, n = 324). Of those, 313 were randomly assigned to the INCT-CRT group, and 315 to the CRT-CNCT group. Median follow-up was 43 months (IQR, 35-49) months in the CAO/ARO/AIO-12 trial and 61,2 months (IQR, 42-68,4) in the OPRA trial. Pooled analysis of baseline clinical and tumor characteristics did not identify any subgroups of patients that would benefit by the one TNT sequence over the other with regard to DFS. INTERPRETATION To our knowledge, this is the first pooled analysis of two randomized trials after direct head-to-head comparison of both TNT sequences. Both trials reported higher rates of complete response with CRT-CNCT, and this should be considered the preferred TNT sequence if organ preservation is a priority.

Abstract
BACKGROUND Liquid biopsy is a minimally invasive procedure investigating tumor mutations. METHODS In our retrospective study, we investigated whether molecular therapy monitoring of patients receiving neoadjuvant radio(chemo)therapy on a daily routine is possible in 17 patients with locally advanced rectal cancer. Six patients received short-course radiotherapy (5 × 5 Gy) with subsequent surgery, six patients were treated according RAPIDO protocol with short-course radiotherapy followed by chemotherapy (FOLFOX4) and subsequent surgery and five patients received conventional neoadjuvant radiochemotherapy with 5-FU followed by surgery. Response was assessed by Dworak. Liquid biopsies were taken before and immediately after neoadjuvant radiotherapy to isolate and ultradeeply sequence cell free DNA with a panel of 127 genes. Somatic mutations were determined bioinformatically by comparison with normal DNA from leukocytes to distinguish them from germline variants or aging mutations. RESULTS In 12 patients (71%) at least one somatic mutation was detected. In 8/12 patients a decrease and in 4/12 an increase or mixed response in ctDNA was seen. Statistical correlation between ctDNA analysis and clinical response could not be seen. CONCLUSION ctDNA is responding to neoadjuvant therapy and liquid biopsy is easily integrated into a daily routine. As part of translational research this protocol leaves room for further investigations.

Abstract
PURPOSE The purpose of this phase 1 trial was to evaluate the safety and toxicity of preoperative short-course chemoradiotherapy (CRT) as part of total neoadjuvant therapy (TNT) for patients with potentially resectable gastric or gastroesophageal adenocarcinoma. METHODS AND MATERIALS Patients were enrolled between March 2021 and December 2022 and received CRT (30 Gy radiation in 10 fractions with concurrent capecitabine or 5-fluorouracil), then received systemic therapy for 2 months, and then underwent surgery. The primary endpoint was CRT safety; secondary endpoints were pathologic complete response, perioperative complications, and overall survival (OS). RESULTS Of the 24 patients enrolled in the trial, 10 (42%) had bleeding, 3 (13%) had gastric outlet obstruction, and 2 (8%) had cirrhosis. Twelve patients (50%) had clinical nodal involvement. Twenty patients (83%) had poorly differentiated tumors, and 13 (54%) had signet ring cell histology. All patients completed CRT. CRT treatment-related toxic effects included grade 3 lymphopenia in 7 patients (29%), grade 4 lymphopenia in 1 (4%), and grade 3 anemia in 1 (4%). After CRT, 22 patients (92%) received chemotherapy, 1 patient (4%) with a microsatellite instability-high tumor received immunotherapy, and 1 patient (4%) underwent resection without systemic therapy. All patients underwent attempted resection, and gastrectomy was performed in 20 (83%). The R0 resection rate was 95%. Two patients had pathologic complete response, and an additional 5 had ≤1% viable tumor. Three patients had surgical complications [grade 1 in 1 patient (4%), grade 3b in 1 (4%), and grade 4a in 1 (4%)]; no patients died within 90 days. The median follow-up time was 28 months, and median OS was not reached. The 1- and 3-year OS rates were 96% and 85%, respectively. CONCLUSION Short-course CRT may be safely used as part of planned TNT for patients with potentially resectable gastric or gastroesophageal adenocarcinoma. The promising rates of treatment completion, pathologic response, and OS support further research of TNT for gastric cancer.

Abstract
Importance Patients with locally advanced rectal cancer and persistent lymph node metastases (PLNM) after neoadjuvant treatment are at high risk of developing locoregional and distant metastasis, yet optimal postsurgical treatment of these patients is limited. Objective To analyze the association of PLNM with pretreatment clinical parameters, intensity of neoadjuvant treatment, and long-term oncological outcomes. Design, Setting, and Participants This cohort study is a post-hoc analysis of 3 randomized clinical trials (Surgical Oncology Working Group of Germany [CAO], Radiological Oncology Working Group of Germany [ARO], and Working Group for Internal Oncology in the German Cancer Society [AIO]) conducted in Germany in 1994, 2004, and 2012 that included 1948 patients with locally advanced rectal cancer recruited between February 1995 and January 2018. Statistical analysis was conducted between September 2023 and February 2024. Exposures Receiving preoperative fluorouracil-based chemoradiotherapy (CRT, comprising the preoperative group of CAO/ARO/AIO-94 and the control group of CAO/ARO/AIO-04), fluorouracil-based CRT plus oxaliplatin (experimental group of CAO/ARO/AIO-04), or total neoadjuvant treatment (TNT) with fluorouracil-based CRT plus oxaliplatin with induction or consolidation leucovorin calcium (folinic acid), fluorouracil, and oxaliplatin chemotherapy within the CAO/ARO/AIO-12 trial. Main Outcome and Measures The associations of PLNM with clinical parameters, intensity of neoadjuvant treatment, and cumulative incidences of LR, DM, and overall survival were assessed. Results A total of 1888 patients (1333 male participants [70.6%]; median [range] age, 62 [19-84] years) with locally advanced rectal adenocarcinoma (clinical tumor stage 3 to 4 and/or clinically node-positive) treated within 3 consecutive clinical trials were analyzed. A total of 522 (29%) experienced PLNM; 378 had lymph node stage (ypN) 1 (20%) after neoadjuvant treatment (ypN) 1 (20%), and 174 had ypN2 (9%). Age, clinical T-stage, N-stage, grading, carcinoembryonic antigen levels, and time interval from completion of CRT to surgery were significantly associated with PLNM, whereas sex and tumor location were not. The percentage of patients with ypN2 stage was almost halved after TNT (18 of 293 patients [6%]) compared with patients treated with fluorouracil-based CRT (114 of 1009 patients [11.3%]; χ26 = 16.693; P = .01). After a median (IQR) follow-up of 54 (37-62) months, 5-year overall survival was 86.1% (95% CI, 83.9%-88.4%) for ypN0, 74.0% (95% CI, 83.9%-88.4%) for ypN1, and 43% for ypN2 (95% CI, 35.4%-52.2%) (P < .001). The 5-year cumulative incidences of locoregional and distant metastases were, respectively, 3% (95% CI, 2.1%-4.2%) and 20% (95% CI, 18%-23%) for ypN0, 6% (95% CI, 3.4%-8.8%) and 40% (95% CI, 34%-46%) for ypN1, and 19% (95% CI, 13%-26%) and 72% (95% CI, 63%-79%) for ypN2 (both P < .001). Conclusions and Relevance In this cohort study, PLNM unmasked an unfavorable phenotype of rectal cancer at high risk for treatment failure. More aggressive adjuvant treatment might be considered; however, risk-adapted surveillance strategies and early recurrence-directed surgery, if feasible, are important strategies in this group of patients with CRT- and/or chemotherapy-resistant disease.

Biondo S, Barrios O, Trenti L, Espin E, Bianco F, Falato A, De Franciscis S, Solis A, Kreisler E. Long-Term Results of 2-Stage Turnbull-Cutait Pull-Through Coloanal Anastomosis for Low Rectal Cancer: A Randomized Clinical Trial. JAMA Surg 2024; 159:990-996. [PMID: 38985480 PMCID: PMC11238068 DOI: 10.1001/jamasurg.2024.2262] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2024] [Accepted: 05/04/2024] [Indexed: 07/11/2024]
Abstract
IMPORTANCE In patients operated on for low rectal cancer, 2-stage Turnbull-Cutait pull-through hand-sewn coloanal anastomosis provides benefits in terms of postoperative morbidity compared with standard hand-sewn coloanal anastomosis associated with diverting ileostomy and further ileostomy reversal. OBJECTIVE To compare long-term results of these 2 techniques after ultralow rectal resection for rectal cancer. DESIGN, Setting, and Participants In this randomized multicenter clinical trial, neither patients nor surgeons were blinded for technique. Patients were recruited in 3 centers. Patients undergoing ultralow anterior rectal resection needing hand-sewn coloanal anastomosis were randomly assigned to 2-stage Turnbull-Cutait pull-through hand-sewn coloanal anastomosis (n = 46) or standard hand-sewn coloanal anastomosis associated with diverting ileostomy (n = 46). INTERVENTIONS All patients underwent ultralow anterior resection. Patients assigned to the 2-stage Turnbull-Cutait pull-through group underwent exteriorization of a segment of left colon through the anal canal. After 6 to 10 days, the exteriorized colon was resected and a delayed hand-sewn coloanal anastomosis performed. For patients assigned to standard coloanal anastomosis, the hand-sewn coloanal anastomosis was performed with diverting ileostomy during the first operation. Ileostomy closure was scheduled after adjuvant treatment was completed in about 6 to 8 months. MAIN OUTCOME AND MEASURE The study aimed to compare the differences between the 2 groups in terms of long-term surgery-related morbidity, functional, and oncological outcomes at 3 years postoperatively. Data were analyzed from October 1, 2018, through October 31, 2021. RESULTS The 92 patients randomized in the first study were included for the 3-year follow-up. The overall morbidity rate in the 2 groups showed that 15 patients (16.3%) had complications with a difference of 6.52 (95% CI, -8.93 to 21.79). Nine patients (19.6%) and 6 patients (13.0%) in the 2-stage Turnbull-Cutait pull-through group and hand-sewn coloanal anastomosis group, respectively, had complications without statistically significant differences (P = .57). Oncological results were comparable between the groups. Long-term fecal continence in the CCA and TCA groups, respectively, assessed using the Wexner Incontinence Score was 10.9 (5.50-15.5) vs 13.0 (7.25-16.0; P = .92), Low Anterior Resection Syndrome score was 32.0 (21.0-37.0) vs 34.0 (23.2-38.5; P = .76), and Colorectal Functional Outcome score was 38.5 (23.0-47.1) vs 40.8 (23.3-58.2; P = .30). CONCLUSIONS AND RELEVANCE In this study, after a 3-year follow-up period, 2-stage Turnbull-Cutait anastomosis for ultralow rectal cancer could be considered as a surgical alternative that has the valuable benefit of avoiding a temporary stoma with similar results in terms of morbidity, fecal continence, patient satisfaction, quality of life, and oncological outcomes when compared with hand-sewn coloanal anastomosis with ileostomy.

Risk factors affecting delay of initiating adjuvant chemotherapy for stage III colorectal cancer. Int J Clin Oncol 2024; 29:1293-1301. [PMID: 38904888 DOI: 10.1007/s10147-024-02567-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2023] [Accepted: 06/03/2024] [Indexed: 06/22/2024]
Abstract
PURPOSE Delay in initiating adjuvant chemotherapy (AC) after curative resection of colorectal cancer (CRC) has been reported to lead to poor prognosis, but few studies have looked at associated factors. This study aimed to identify risk factors for delay in initiating AC. METHODS Data from 200 consecutive patients who underwent curative resection and AC for stage III CRC between 2013 and 2018 were retrospectively collected and analyzed. RESULTS AC was initiated more than 8 weeks after surgery in 12.5% of patients (the delay group). Compared to those with no delay (the non-delay group), patients in the delay group had significantly higher rates of synchronous double cancers (2.3% vs. 16.0%, p = 0.001), preoperative bowel obstruction (10.3% vs. 32.0%, p = 0.003), laparotomy (56.0% vs. 80.0%, p = 0.02), concomitant resection (2.9% vs. 24.0%, p < 0.001), and postoperative complications (32.0% vs. 56.0%, p = 0.02), and a significantly longer length of hospital stay (median 12 vs. 30 days, p < 0.001). In multivariate analysis, synchronous double cancers (odds ratio 10.2, p = 0.008), preoperative bowel obstruction (odds ratio 4.6, p = 0.01), concomitant resection (odds ratio 5.2, p = 0.03), and postoperative complications of Clavien-Dindo grade ≥ IIIa (odds ratio 4.0, p = 0.03) were identified as independent risk factors for delay in initiating AC. CONCLUSION Careful preoperative treatment planning for CRC patients with synchronous double cancers, preoperative bowel obstruction, and concomitant resection, and management for postoperative complication are necessary to avoid delay in initiating AC.

Cancer Treat Rev 2024; 129:102796. [PMID: 38968742 DOI: 10.1016/j.ctrv.2024.102796] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2024] [Revised: 06/27/2024] [Accepted: 06/28/2024] [Indexed: 07/07/2024]
Abstract
Overall survival benefit of total neoadjuvant treatment (TNT) remains unconfirmed. Thus, in our opinion, the main rationale for using TNT is a planned watch-and-wait (w&w) strategy to improve patients' long-term quality of life through organ preservation. The OPRA randomized trial, which examined a planned w&w strategy using TNT, showed a higher organ preservation rate but also a higher regrowth rate compared to studies on the opportunistic w&w strategy. Higher rates of complete clinical response with TNT did not improve disease-free survival compared to historical controls. Therefore, the gain in organ-sparing capability might not be balanced by the increased oncological risk. The ultimate local failure rate in the intention-to-treat analysis of the OPRA trial was 13% for induction chemotherapy and 16% for consolidation chemotherapy, which seems higher than expected compared to 8% in a meta-analysis of w&w studies or 12% after TNT and surgery in the PRODIGE-23 and RAPIDO trials, which enrolled patients with more advanced cancers than the OPRA trial. Other studies also suggest worse local control when surgery is delayed for radio-chemoresistant cancers. Our review questions the safety of the planned w&w strategy using TNT in unselected patients. To reduce the oncological risk while maintaining high organ preservation rates, we suggest that the planned w&w strategy using TNT requires a two-tier patient selection process: before treatment and after tumor response assessment at the midpoint of consolidation chemotherapy. These robust selections should identify patients who are unlikely to achieve organ preservation with TNT and would be better managed by preoperative chemoradiotherapy (without consolidation chemotherapy) and surgery, or by discontinuing consolidation chemotherapy and proceeding directly to surgery.

Abstract
BACKGROUND Neoadjuvant radiation and oxaliplatin-based systemic therapy (total neoadjuvant therapy-TNT) have been shown to increase response and organ-preservation rates in localized rectal cancer. However, trials have been heterogeneous regarding treatment protocols and few have used a watch-and-wait (WW) approach for complete responders. This trial evaluates if conventional long-term chemoradiation followed by consolidation of FOLFIRINOX increases complete response rates and the number of patients managed by WW. METHODS This was a pragmatic randomized phase II trial conducted in 2 Cancer Centers in Brazil that included patients with T3+ or N+ rectal adenocarcinoma. After completing a long-course 54 Gy chemoradiation with capecitabine patients were randomized 1:1 to 4 cycles of mFOLFIRINOX (Oxaliplatin 85, irinotecan 150, 5-FU 2400)-TNT-arm-or to the control arm, that did not include further neoadjuvant treatment. All patients were re-staged with dedicated pelvic magnetic resonance imaging and sigmoidoscopy 12 weeks after the end of radiation. Patients with a clinical complete response were followed using a WW protocol. The primary endpoint was complete response: clinical complete response (cCR) or pathological response (pCR). RESULTS Between April 2021 and June 2023, 55 patients were randomized to TNT and 53 to the control arm. Tumors were 74% stage 3, median distance from the anal verge was 6 cm, 63% had an at-risk circumferential margin, and 33% an involved sphincter. The rates of cCR + pCR were (31%) for TNT versus (17%) for controls (odds ratio 2.19, CI 95% 0.8-6.22 P = .091) and rates of WW were 16% and 9% (P = ns). Median follow-up was 8.1 months and recurrence rates were 16% versus 21% for TNT and controls (P = ns). CONCLUSIONS TNT with consolidation FOLFIRINOX is feasible and has high response rates, consistent with the current literature for TNT. This trial was supported by a grant from the Brazilian Government (PROADI-SUS - NUP 25000.164382/2020-81).

Abstract
Background and purpose This exploratory prospective observational study investigated the changes in Health-related Quality of Life (HRQoL) in rectal cancer patients (RCPs), from diagnosis to one-year-post-surgery follow-up and explored the role of physical symptoms and psychological determinants on HRQoL at the different time points. Materials and methods We assessed HRQoL, psychological distress, coping, affectivity, alexithymia and social support in 43 RCPs treated with preoperative (chemo)radiation and surgery, at three different assessment time points: diagnosis (T0), one month after the end of preoperative treatment (T1), one month after resection surgery (T2), and at follow-up (T3). Results The data showed that HRQoL decreased during active treatments, especially between T1 and T2 (p = 0.005), before increasing again at follow-up (p = 0.002).Baseline intestinal symptoms (p < 0.001) and negative affectivity trait (p = 0.03) significantly predicted HRQoL at T0. Baseline pain (p < 0.001), intestinal (p = 0.003) and urinary (p = 0.009) symptoms at T1 significantly predicted HRQoL at T1. A fatalistic coping style at T1 (p = 0.013), psychological distress (p = 0.003), mouth symptoms (p = 0.001) at T2 significantly predicted HRQoL at T2. Similarly, a fatalistic coping style at T1 (p = 0.006), psychological distress (p = 0.004), mouth (p = 0.002) and pain symptoms (p = 0.002) at T3 significantly predicted HRQoL at T3. Conclusion Several physical and psychological factors are involved in the changes occurring after diagnosis in RCPs' HRQoL. While cancer-related symptoms and treatment-related physical side effects are the main predictors of HRQoL at diagnosis and during active treatments, early psychological reactions have a higher predictive weight in post-treatment HRQoL.These data emphasise the importance of active screening, early diagnosis, and preventive psychological interventions immediately after diagnosis to improve HRQoL and psychological health outcomes.

Abstract
Background and Objective Magnetic resonance guided radiotherapy (MRgRT) is an emerging technological innovation with more and more institutions gaining clinical experience in this new field of radiation oncology. The ability to better visualize both tumors and healthy tissues due to excellent soft tissue contrast combined with new possibilities regarding motion management and the capability of online adaptive radiotherapy might increase tumor control rates while potentially reducing the risk of radiation-induced toxicities. As conventional computed tomography (CT)-based image guidance methods are insufficient for adaptive workflows in abdominal tumors, MRgRT appears to be an optimal method for this tumor site. The aim of this narrative review is to outline the opportunities and challenges in magnetic resonance guided radiation therapy in gastrointestinal cancers. Methods We searched for studies, reviews and conceptual articles, including the general technique of MRgRT and the specific utilization in gastrointestinal cancers, focusing on pancreatic cancer, liver metastases and primary liver cancer, rectal cancer and esophageal cancer. Key Content and Findings This review is highlighting the innovative approach of MRgRT in gastrointestinal cancer and gives an overview of the currently available literature with regard to clinical experiences and theoretical background. Conclusions MRgRT is a promising new tool in radiation oncology, which can play off several of its beneficial features in the specific field of gastrointestinal cancers. However, clinical data is still scarce. Nevertheless, the available literature points out large potential for improvements regarding dose coverage and escalation as well as the reduction of dose exposure to critical organs at risk (OAR). Further prospective studies are needed to demonstrate the role of this innovative technology in gastrointestinal cancer management, in particular trials that randomly compare MRgRT with conventional CT-based image-guided radiotherapy (IGRT) would be of high value.

Abstract
Total mesorectal excision (TME) has greatly improved rectal cancer surgery outcomes by reducing local recurrence and enhancing patient survival. This review outlines essential knowledge and techniques for performing TME. TME emphasizes the complete resection of the mesorectum along embryologic planes to minimize recurrence. Key anatomical insights include understanding the rectal proper fascia, Denonvilliers fascia, rectosacral fascia, and the pelvic autonomic nerves. Technical tips cover a step-by-step approach to pelvic dissection, the Gate approach, and tailored excision of Denonvilliers fascia, focusing on preserving pelvic autonomic nerves and ensuring negative circumferential resection margins. In Korea, TME has led to significant improvements in local recurrence rates and survival with well-adopted multidisciplinary approaches. Surgical techniques of TME have been optimized and standardized over several decades in Korea, and minimally invasive surgery for TME has been rapidly and successfully adopted. The review emphasizes the need for continuous research on tumor biology and precise surgical techniques to further improve rectal cancer management. The ultimate goal of TME is to achieve curative resection and function preservation, thereby enhancing the patient's quality of life. Accurate TME, multidisciplinary-based neoadjuvant therapy, refined sphincter-preserving techniques, and ongoing tumor research are essential for optimal treatment outcomes.

Abstract
Rectal cancer management has evolved significantly, particularly with neoadjuvant treatment strategies. This narrative review examines the development and effectiveness of these therapies for locally advanced rectal cancer (LARC), highlighting the historical quest that led to current neoadjuvant alternatives. Initially, trials showed the benefits of adding radiotherapy (RT) and chemotherapy (CT) to surgery, reducing local recurrence (LR). The addition of oxaliplatin to chemoradiotherapy (CRT) further improved outcomes. TNT integrates chemotherapy and radiotherapy preoperatively to enhance adherence, timing, and systemic control. Key trials, including PRODIGE 23, CAO/ARO/AIO 12, OPRA, RAPIDO, and STELLAR, are analyzed to compare short-course and long-course RT with systemic chemotherapy. The heterogeneity and difficulty in comparing TNT trials due to different designs and outcomes are acknowledged, along with their promising long-term results. On the other hand, it briefly discusses the potential for non-operative management (NOM) in select patients, a strategy gaining traction due to favorable outcomes in specific trials. As a conclusion, this review underscores the complexity of rectal cancer treatment, emphasizing individualized approaches considering patient preferences and healthcare resources. It also highlights the importance of interpreting impressive positive or negative results with caution due to the variability in study designs and patient populations.

BMC Cancer 2024; 24:901. [PMID: 39060961 PMCID: PMC11282593 DOI: 10.1186/s12885-024-12529-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/22/2024] [Accepted: 06/17/2024] [Indexed: 07/28/2024] Open
Abstract
BACKGROUND Recent data have demonstrated that in locally advanced rectal cancer (LARC), a total neoadjuvant therapy (TNT) approach improves compliance with chemotherapy and increases rates of tumor response compared to neoadjuvant chemoradiation (CRT) alone. They further indicate that the optimal sequencing of TNT involves consolidation (rather than induction) chemotherapy to optimize complete response rates. Data, largely from retrospective studies, have also shown that patients with clinical complete response (cCR) after TNT may be managed safely with the watch and wait approach (WW) instead of preemptive total mesorectal resection (TME). However, the optimal consolidation chemotherapy regimen to achieve cCR has not been established, and a randomized clinical trial has not robustly evaluated cCR as a primary endpoint. Collaborating with a multidisciplinary oncology team and patient groups, we designed this NCI-sponsored study of chemotherapy intensification to address these issues and to drive up cCR rates, to provide opportunity for organ preservation, improve quality of life for patients and improve survival outcomes. METHODS In this NCI-sponsored multi-group randomized, seamless phase II/III trial (1:1), up to 760 patients with LARC, T4N0, any T with node positive disease (any T, N +) or T3N0 requiring abdominoperineal resection or coloanal anastomosis and distal margin within 12 cm of anal verge will be enrolled. Stratification factors include tumor stage (T4 vs T1-3), nodal stage (N + vs N0) and distance from anal verge (0-4; 4-8; 8-12 cm). Patients will be randomized to receive neoadjuvant long-course chemoradiation (LCRT) followed by consolidation doublet (mFOLFOX6 or CAPOX) or triplet chemotherapy (mFOLFIRINOX) for 3-4 months. LCRT in both arms involves 4500 cGy in 25 fractions over 5 weeks + 900 cGy boost in 5 fractions with a fluoropyrimidine (capecitabine preferred). Patients will undergo assessment 8-12 (± 4) weeks post-TNT completion. The primary endpoint for the phase II portion will compare cCR between treatment arms. A total number of 312 evaluable patients (156 per arm) will provide statistical power of 90.5% to detect a 17% increase in cCR rate, at a one-sided alpha = 0.048. The primary endpoint for the phase III portion will compare disease-free survival (DFS) between treatment arms. A total of 285 DFS events will provide 85% power to detect an effect size of hazard ratio 0.70 at a one-sided alpha of 0.025, requiring enrollment of 760 patients (380 per arm). Secondary objectives include time-to event outcomes (overall survival, organ preservation time and time to distant metastasis) and adverse event rates. Biospecimens including archival tumor tissue, plasma and buffy coat, and serial rectal MRIs will be collected for exploratory correlative research. This study, activated in late 2022, is open across the NCTN and had accrued 330 patients as of May 2024.

DISCUSSION Building on data from modern day rectal cancer trials and patient input from national advocacy groups, we have designed The Janus Rectal Cancer Trial studying chemotherapy intensification via a consolidation chemotherapy approach with the intent to enhance cCR and DFS rates, increase organ preservation rates, and improve quality of life for patients with rectal cancer.

Abstract
ABSTRACT In locally advanced rectal cancer, neoadjuvant treatment has evolved from no preoperative treatment to the addition of radiation and systemic therapy and ultimately total neoadjuvant therapy. Total neoadjuvant therapy is the completion of preoperative radiation or chemoradiation and chemotherapy before surgery in order to maximize tumor response and improve survival outcomes. This review summarizes the literature of the neoadjuvant approaches related to locally advanced rectal cancer and highlights the nuances of selecting the appropriate treatment.

Abstract
BACKGROUND AND OBJECTIVES Pathological nodal staging is relevant to postoperative decision-making and a prognostic marker of cancer survival. This study aimed to assess the effect of different total neoadjuvant therapy (TNT) regimens on lymph node status following total mesorectal excision (TME) for locally advanced rectal cancer (LARC). METHODS A retrospective cohort study of patients treated for node-positive clinical stage 3 LARC with TNT between January 2015 and August 2022. Patients were stratified into induction therapy and consolidation therapy groups. Variables collated included patient demographics, clinical and radiological characteristics of the tumor, and pathology of the resected specimen. Primary outcome was total harvested lymph nodes. RESULTS Ninety-seven patients were included (57 [58.8%] males; mean age of 58.5 ± 11.4 years). The induction therapy group included 85 (87.6%) patients while 12 (12.4%) patients received consolidation therapy. A median interquartile range value of 22.00 (5.00-72.00) harvested lymph nodes was recorded for the induction therapy group in comparison to 16.00 (16.00-47.00) in the consolidation therapy arm (p = 0.487). Overall pathological complete response rate was 34%. CONCLUSION Total harvested nodes from resected specimens were marginally lower in the consolidation therapy group. Induction therapy may be preferrable to optimize postoperative specimen staging.

[PMID: 38911065 PMCID: PMC11190348 DOI: 10.1002/mco2.609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2023] [Revised: 04/18/2024] [Accepted: 05/16/2024] [Indexed: 06/25/2024] Open
Abstract
Our study investigated whether magnetic resonance imaging (MRI)-based radiomics features could predict good response (GR) to neoadjuvant chemoradiotherapy (nCRT) and clinical outcome in patients with locally advanced rectal cancer (LARC). Radiomics features were extracted from the T2 weighted (T2W) and Apparent diffusion coefficient (ADC) images of 1070 LARC patients retrospectively and prospectively recruited from three hospitals. To create radiomic models for GR prediction, three classifications were utilized. The radiomic model with the best performance was integrated with important clinical MRI features to create the combined model. Finally, two clinical MRI features and ten radiomic features were chosen for GR prediction. The combined model, constructed with the tumor size, MR-detected extramural venous invasion, and radiomic signature generated by Support Vector Machine (SVM), showed promising discrimination of GR, with area under the curves of 0.799 (95% CI, 0.760-0.838), 0.797 (95% CI, 0.733-0.860), 0.754 (95% CI, 0.678-0.829), and 0.727 (95% CI, 0.641-0.813) in the training and three validation datasets, respectively. Decision curve analysis verified the clinical usefulness. Furthermore, according to Kaplan-Meier curves, patients with a high likelihood of GR as determined by the combined model had better disease-free survival than those with a low probability. This radiomics model was developed based on large-sample size, multicenter datasets, and prospective validation with high radiomics quality score, and also had clinical utility.

Abstract
ABSTRACT The optimal management of T3N0 rectal cancer is an area of active debate that has withstood multiple decades of research. In this comprehensive review, we delve into the many nuances that come with treating T3N0 rectal cancer, particularly examining the role and evolution of radiation therapy. We review both the historical paradigms and latest advances in treatment and highlight the significance of precise preoperative staging. As the field continues to evolve, this review highlights a shift toward more tailored treatments, considering both patient goals and the desire for optimal oncologic outcomes. In the current era, clinical decision-making for T3N0 rectal cancer requires a patient-centric approach that balances effective therapy while minimizing undue side effects.

Abstract
Though resection has been the mainstay of treatment for nonmetastatic rectal cancer over the past century, radiation has become an increasingly integral component of care for locally advanced disease. Today, two predominant radiotherapy approaches-hyperfractionated chemoradiotherapy and "short-course" radiation-are widely utilized to reduce local recurrence and, in some cases, cure disease. Both have been incorporated into total neoadjuvant therapy (TNT) regimens and achieved excellent local control and superior complete response rates compared to chemoradiation alone. Additionally, initial results of "watch and wait" protocols utilizing either radiation modality have been promising. Yet, differences do exist; though short course is cheaper and more convenient for patients, recently published data may show superior complete response and local recurrence rates with chemoradiation. Ultimately, direct comparisons of short-course radiotherapy against chemoradiation within the TNT framework are needed to identify optimal radiation regimens in the treatment of locally advanced rectal cancer.

Abstract
BACKGROUND Preoperative chemoradiotherapy (CRT) followed by surgery is the standard treatment for locally advanced rectal cancer (LARC). We reported the short-term outcomes of the VOLTAGE trial that investigated the safety and efficacy of preoperative CRT followed by nivolumab and surgery. Here, we present the 3-year outcomes of this trial. METHODS Thirty-nine patients with microsatellite stable (MSS) LARC and five patients with microsatellite instability-high (MSI-H) LARC underwent CRT (50.4 Gy) followed by five doses of nivolumab (240 mg) and surgery. The 3-year relapse-free survival (RFS), overall survival (OS), and associations with biomarkers were evaluated. RESULTS The 3-year RFS rates in patients with MSS and MSI-H were 79.5% and 100%, respectively, and the 3-year OS rates were 97.4% and 100%, respectively. Of the MSS patients, those with pre-CRT PD-L1 positivity, pre-CRT high CD8 + T cell/effector regulatory T cell (eTreg) ratio, pre-CRT high expression of Ki-67, CTLA-4, and PD-1 had a trend toward better 3-year RFS than those without. CONCLUSIONS Three-year outcomes of patients with MSI-H were better than those of patients with MSS. PD-L1 positivity, elevated CD8/eTreg ratio, and high expression of Ki-67, CTLA-4, and PD-1 could be positive predictors of prognosis in patients with MSS.

Abstract
BACKGROUND Pathologic complete response after neoadjuvant chemoradiotherapy for rectal cancer is associated with improved survival. It is unclear whether residual carcinoma in situ portends a similar outcome. OBJECTIVE To compare the survival of patients with locally advanced rectal cancer who received neoadjuvant therapy and achieved pathologic carcinoma in situ versus pathologic complete response. DESIGN Retrospective cohort study. SETTING National public database. PATIENTS A total of 4594 patients in the National Cancer Database from 2006 to 2016 with locally advanced rectal cancer who received neoadjuvant therapy, underwent surgery, and had node-negative ypTis or ypT0 on final pathology were included. Of these, 4321 patients (94.1%) had ypT0 and 273 (5.9%) had ypTis on final pathology. MAIN OUTCOME MEASURE Overall survival. RESULTS The median age was 60 years, and 1822 patients (39.7%) were women. On initial staging, 54.5% (n = 2503) had stage II disease and 45.5% (n = 2091) had stage III disease. The ypTis group had decreased overall survival compared to the ypT0 group (HR 1.42; 95% CI, 1.04-1.95; p = 0.028). Other factors associated with decreased overall survival were older age at diagnosis, increasing Charlson-Deyo score, and poorly differentiated tumor grade. Variables associated with improved survival were female sex, private insurance, and receipt of both neoadjuvant and adjuvant chemotherapy. For the total cohort, there was no difference in survival between clinical stage II and stage III. LIMITATIONS Standard therapy versus total neoadjuvant therapy could not be abstracted. Overall survival was defined as the time from surgery to death from any cause or last contact, allowing for some erroneously misclassified deaths. CONCLUSIONS ypTis is associated with worse overall survival than ypT0 for patients with locally advanced rectal cancer who receive neoadjuvant chemoradiotherapy followed by surgery. For this cohort, clinical stage was not a significant predictor of survival. Prospective trials comparing survival for these pathologic outcomes are needed. See Video Abstract .

Abstract
Liver metastases are seen in at least 60% of patients with colorectal cancer at some point during the course of their disease. The management of both primary and liver disease is uniquely challenging in rectal cancer due to competing treatments and complex sequence of treatments depending on the clinical presentation of disease. Recently, several novel concepts are shaping new treatment paradigms, including changes in timing, sequence, and duration of therapies combined with potential deescalation of treatment components. Overall, the treatment of this clinical scenario mandates multidisciplinary evaluation and personalization of care; however, there is still considerable debate regarding the timing of liver metastasectomy in the context of the overall treatment plan. Herein, we will discuss the current literature on management of rectal cancer with synchronous liver metastasis, current treatment approaches with respect to chemotherapy, and role of hepatic artery infusion therapy.

Abstract
This cross-sectional survey study aimed to explore the knowledge, attitude, and practice (KAP) toward total neoadjuvant therapy (TNT) for rectal cancer (RC) among specialists in Hainan Province, China. RC specialists working in Hainan Province (China) were enrolled in this cross-sectional study between March and June 2023. A self-designed questionnaire was used to collect the participants' characteristics and KAP toward TNT for RC. A total of 279 valid questionnaires were collected. The KAP scores were 15.91 ± 6.02 (possible range: 0-24), 34.16 ± 5.11 (possible range: 10-50), and 12.42 ± 1.83 (possible range: 3-15), respectively. The KAP scores of specialists who had applied TNT in clinical practice or research and had evaluated RC patients treated with TNT were significantly higher than those who had not (all P < 0.05). The structural equation model showed that knowledge of TNT directly affected attitude (β = 0.292, P = 0.007) and practice (β = 0.912, P = 0.007), and attitude toward TNT also had a direct effect on practice (β = 1.047, P = 0.008). In conclusion, RC specialists in Hainan (China) had inadequate knowledge, negative attitudes, and sufficient practice toward TNT in Hainan Province, China. It is necessary to enhance education for RC specialists to improve their knowledge and attitude toward TNT.

Non-small Cell Lung Cancer]. ZHONGGUO FEI AI ZA ZHI = CHINESE JOURNAL OF LUNG CANCER 2024; 27:421-430. [PMID: 39026493 PMCID: PMC11258643 DOI: 10.3779/j.issn.1009-3419.2024.102.26] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Subscribe] [Scholar Register] [Received: 05/18/2024] [Indexed: 07/20/2024]
Abstract
BACKGROUND Lung cancer is the cancer with the highest incidence and mortality rates in China, and non-small cell lung cancer (NSCLC) accounts for 80%-85% of all malignant lung tumors. Currently, surgical treatment remains the primary treatment modality for lung cancer. In recent years, the effectiveness of immune checkpoint inhibitors for NSCLC has become a consensus, and neoadjuvant immunochemotherapy (nICT) has shown promising efficacy and safety in early to intermediate stage NSCLC. However, there are fewer studies related to nICT for locally advanced NSCLC. This study aims to evaluate the efficacy and safety of nICT therapy in locally advanced resectable NSCLC. METHODS 85 confirmed resectable stage IIIA and IIIB patients treated in the Department of Thoracic Surgery, Second Hospital of Lanzhou University, from January 2021 to April 2024, were divided into the nICT group (n=32) and the surgery alone group (n=53). Clinical baseline data, perioperative indicators, postoperative complications, imaging response rate, pathological response rate, incidence of adverse events, and quality of life were compared between the two groups. RESULTS There were no statistically significant differences in clinical baseline data between the two groups (P>0.05). Incidence of choosing thoracotomy was higher in the nICT group than in the surgery alone group (P=0.002). There were no significant differences in surgical time, intraoperative blood loss, number of dissected lymph nodes, duration of chest tube placement, postoperative hospital stay, and R0 resection rate between the two groups (P>0.05). The overall incidence of postoperative complications was 31.25% in the nICT group and 22.64% in the surgery alone group, with no statistically significant difference (P=0.380). In the nICT group, the objective response rate (ORR) was 84.38%, with 5 cases of complete response (CR)(15.63%), 22 cases of partial response (PR)(68.75%), 15 cases of pathological response rate (pCR)(46.88%), and 11 cases of major pathological reaponse (MPR) (34.38%). During nICT treatment, 12 cases (37.50%) experienced grade 3 treatment-related adverse events, no death induced by adverse events or immune related adverse events. Moreover, the symptoms of the patients were improved after nICT treatment. CONCLUSIONS Neoadjuvant immunochemotherapy shows promising efficacy in locally advanced resectable NSCLC, with manageable treatment-related adverse events. It is a safe and feasible neoadjuvant treatment modality for locally advanced resectable NSCLC.

Abstract
BACKGROUND Survival data on patients with locally advanced rectal cancer (LARC) undergoing non-operative management (NOM) in a real-world setting are lacking. METHODS We analyzed LARC patients from the National Cancer Database with the following features: treated between 2010 and 2020, age 18-65 years, Charlson comorbidity index (CCI) ≤ 1, received neoadjuvant multiagent chemotherapy plus radiation ≥ 45 Gray, and underwent surgery or NOM. Patients were stratified into two groups: (A) clinical T1-3 tumors with positive nodes (cT1-3N+) and (B) clinical T4 tumors, N+/- (cT4N+/-). We performed a comparative analysis of overall survival (OS) with NOM versus surgery by the Kaplan-Meier method and propensity score matching. Additionally, a multivariable analysis explored the association between NOM and OS. RESULTS NOM exhibited significantly lower OS than surgery in both groups. In cT1-3N+ patients, NOM resulted in a 5-year OS of 73.9% (95% confidence interval [CI] = 69.7-77.6%) versus 84.5% (95% CI = 83.6-85.3%) with surgery (p < 0.001). In the cT4N+/- group, NOM yielded a 5-year OS of 44.5% (95% CI = 37.0-51.8%) versus 72.5% (95% CI = 69.9-74.8%) with surgery (p < 0.001). Propensity score matching and multivariable analyses revealed similar conclusions. CONCLUSION Patients with LARC undergoing NOM versus surgery in real-world settings appear to have inferior survival.

Abstract
Importance Treatment of locally advanced rectal cancer (LARC) involves neoadjuvant chemoradiotherapy plus total mesorectal excision and adjuvant chemotherapy. However, total neoadjuvant therapy (TNT) protocols (ie, preoperative chemotherapy in addition to radiotherapy) may allow better adherence and early treatment of distant micrometastases and may increase pathological complete response (pCR) rates. Objective To assess the efficacy and tolerability of TNT protocols for LARC. Data Sources MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and Web of Science Core Collection electronic databases and ClinicalTrials.gov for unpublished studies were searched from inception to March 2, 2024. Study Selection Randomized clinical trials including adults with LARC who underwent rectal resection as a final treatment were included. Studies including nonoperative treatment (watch-and-wait strategy), treatments other than rectal resection, immunotherapy, or antiangiogenic agents were excluded. Among the initially identified studies, 2.9% met the selection criteria. Data Extraction and Synthesis Two authors independently screened the records and extracted data. Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA)-compliant pairwise and network meta-analyses with a random-effects model were performed in a frequentist framework, and the certainty of evidence was assessed according to the confidence in network meta-analysis approach. Main Outcomes and Measures The primary outcome was pCR, defined as the absence of residual tumor at pathological assessment after surgery. Secondary outcomes included tolerability, toxic effects, perioperative outcomes, and long-term survival. Results Of 925 records identified, 27 randomized clinical trials, including 13 413 adults aged 18 years or older (median age, 60.0 years [range, 42.0-63.5 years]; 67.2% male) contributed to the primary network meta-analysis. With regard to pCR, long-course chemoradiotherapy (L-CRT) plus consolidation chemotherapy (relative risk [RR], 1.96; 95% CI, 1.25-3.06), short-course radiotherapy (S-RT) plus consolidation chemotherapy (RR, 1.76; 95% CI, 1.34-2.30), and induction chemotherapy plus L-CRT (RR, 1.57; 95% CI, 1.09-2.25) outperformed standard L-CRT with single-agent fluoropyrimidine-based chemotherapy. Considering 3-year disease-free survival, S-RT plus consolidation chemotherapy (RR, 1.08; 95% CI, 1.01-1.14) and induction chemotherapy plus L-CRT (RR, 1.12; 95% CI, 1.01-1.24) outperformed L-CRT, in spite of an increased 5-year locoregional recurrence rate of S-RT plus consolidation chemotherapy (RR, 1.65; 95% CI, 1.03-2.63). Conclusions and Relevance In this systematic review and network meta-analysis, 3 TNT protocols were identified to outperform the current standard of care in terms of pCR rates, with good tolerability and optimal postoperative outcomes, suggesting they should be recognized as first-line treatments.

Abstract
Over the past two decades, metronomic chemotherapy has gained considerable attention and has demonstrated remarkable success in the treatment of cancer. Through chronic administration and low-dose regimens, metronomic chemotherapy is associated with fewer adverse events but still effectively induces disease control. The identification of its antiangiogenic properties, direct impact on cancer cells, immunomodulatory effects on the tumour microenvironment, and metabolic reprogramming ability has established the intrinsic multitargeted nature of this therapeutic approach. Recently, the utilization of metronomic chemotherapy has evolved from salvage treatment for metastatic disease to adjuvant maintenance therapy for high-risk cancer patients, which has been prompted by the success of several substantial phase III trials. In this review, we delve into the mechanisms underlying the antitumour effects of metronomic chemotherapy and provide insights into potential combinations with other therapies for the treatment of various malignancies. Additionally, we discuss health-economic advantages and candidates for the utilization of this treatment option.

Abstract
The treatment of patients with localized rectal cancer is complex and requires input from a multidisciplinary team. Baseline local staging and mismatch repair protein testing are vital to develop individualized treatment plans. There are multiple options in terms of treatment modalities and sequencing, including transanal excision, short-course radiation, long-course chemoradiation, chemotherapy doublet or triplet, nonoperative management, and immune checkpoint blockade for patients with mismatch repair deficient tumors. While localized colon cancer is typically treated with surgical resection and consideration of adjuvant chemotherapy, emerging data suggest that neoadjuvant chemotherapy may be beneficial in patients with higher-risk disease. Quality-of-life considerations are imperative to prevent potential chronic effects on psychosocial health, neuropathy, fertility, and bowel, bladder, and sexual function. The omission of radiation or surgery can mitigate these toxicities without diminishing oncologic outcomes. The optimal treatment plan and sequence is not a one-size-fits-all approach but rather should be personalized to the patient's disease burden, tumor location, comorbidities, and preferences.

Abstract
Despite therapeutic advancements, disease-free survival and overall survival of patients with locally advanced rectal cancer have not improved in most trials as a result of distant metastases. For treatment decision-making, both long-term oncologic outcomes and impact on quality-of-life indices should be considered (for example, bowel function). Total neoadjuvant therapy (TNT), comprised of chemotherapy and radiotherapy or chemoradiotherapy, is now a standard treatment approach in patients with features of high-risk disease to prevent local recurrence and distant metastases. In selected patients who have a clinical complete response, subsequent surgery might be avoided through non-operative management, but patients who do not respond to TNT have a poor prognosis. Refined molecular characterization might help to predict which patients would benefit from TNT and non-operative management. Specifically, integrated analysis of spatiotemporal multi-omics using artificial intelligence and machine learning is promising. Three prospective trials of TNT and non-operative management in Japan, the USA and Germany are collaborating to better understand drivers of response to TNT. Here, we address the future direction for TNT.

A retrospective cohort study of neoadjuvant chemoradiotherapy combined with immune checkpoint inhibitors in locally advanced rectal cancer. Transl Oncol 2024; 44:101955. [PMID: 38583351 PMCID: PMC11004196 DOI: 10.1016/j.tranon.2024.101955] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 03/14/2024] [Accepted: 04/03/2024] [Indexed: 04/09/2024] Open
Abstract
INTRODUCTION This study aimed to investigate the safety and efficacy of neoadjuvant chemoradiotherapy combined with immune checkpoint inhibitors (ICIs) in patients with locally advanced rectal cancer (LARC). Patients diagnosed with LARC and treated with programmed cell death protein-1 (PD-1) inhibitors were recruited. METHODS Four different treatment strategies were employed in this study: plan A [long-course radiotherapy + PD-1 inhibitor/capecitabine + PD-1 inhibitor/XELOX+ total mesorectal excision (TME)], plan B (long-course radiotherapy + capecitabine + PD-1 inhibitor/XELOX + TME), plan C (short-course radiotherapy + PD-1 inhibitor/XELOX + TME), and plan D (PD-1 inhibitor/XELOX + short-course radiotherapy + TME). The basic information about patients, pathological indicators, adverse events, and efficacy indexes of treatment plans were analyzed. RESULTS 96.8 % of patients were mismatch repair proficient (pMMR) and only 2 patients belonged to mismatch repair deficient (dMMR). The 2 patients with dMMR showed a pathological complete response (pCR) rate of 100 %, while the pCR rate of pMMR patients was 43.3 %. The overall tumor descending rate reached 79 %, and the anus-retained rate was 88.7 % in all LARC patients. Plan A exhibited the highest pCR rate of 60 %, and plan C had the highest tumor descending rate and anal preservation rate. Radiation enteritis was the most common adverse event in LARC patients after neoadjuvant therapy, and its incidence was the highest in Plan A. CONCLUSION Neoadjuvant chemoradiotherapy combined with ICIs demonstrated favorable efficacy and safety in treating LARC patients.

Abstract
BACKGROUND The treatment of locally advanced rectal cancer (LARC) has evolved following recent landmark trials of total neoadjuvant therapy (TNT)-the delivery of preoperative chemotherapy sequenced with radiation. AIM To assess the preferences of colorectal surgery (CRS), radiation oncology (RO) and medical oncology (MO) specialists attending the All-Ireland Colorectal Cancer Conference (AICCC) 2022 regarding the neoadjuvant management of LARC. METHODS A live electronic survey explored the preferred treatment approach and TNT regimen for early-, intermediate-, bad-, and advanced-risk categories of rectal cancer according to the European Society of Medical Oncology (ESMO) guidelines. The survey was preceded by an update from lead investigators of TNT trials (OPRA, PRODIGE-23 and RAPIDO), who then participated in a multidisciplinary panel discussion. RESULTS Ten CRS, 7 RO and 15 MO (32 of 45 specialists) participated fully in the survey resulting in a response rate of 71%. Ninety-four percent, 76% and 53% of specialists preferred a TNT approach for patients with advanced, bad, and intermediate-risk rectal cancer, respectively. A consolidation TNT regimen of long-course chemoradiotherapy followed by chemotherapy was the most preferred regimen. Upfront surgery was preferred by 77% for early-risk disease. CONCLUSION This survey illustrated the general acceptance of TNT by rectal cancer specialists attending the AICCC as a valuable treatment strategy for higher-risk category LARC. Whilst the treatment of LARC changes, it remains best practice to individualize care, incorporating the selective use of TNT as discussed by an MDT and in keeping with the patient's goals of care.

Abstract
Total neoadjuvant therapy (TNT) is a novel strategy for rectal cancer that administers both (chemo)radiotherapy and systemic chemotherapy before surgery. TNT is expected to improve treatment compliance, tumor regression, organ preservation, and oncologic outcomes. Multiple TNT regimens are currently available with various combinations of the treatments including induction or consolidation chemotherapy, triplet or doublet chemotherapy, and long-course chemoradiotherapy or short-course radiotherapy. Evidence on TNT is rapidly evolving with new data on clinical trials, and no definitive consensus has been established on which regimens to use for improving outcomes. Clinicians need to understand the advantages and limitations of the available regimens for multidisciplinary decision making. This article reviews currently available evidence on TNT for rectal cancer. A decision making flow chart is provided for tailor-made use of TNT regimens based on tumor location and local and systemic risk.

Abstract
For patients with rectal cancer, the standard approach of chemotherapy, radiation therapy, and surgery (trimodality therapy) is associated with significant long-term toxicity and/or colostomy for most patients. Patient options focused on quality of life (QOL) have dramatically improved, but there remains limited guidance regarding comparative effectiveness. This systematic review and associated guidelines evaluate how various treatment strategies compare to each other in terms of oncologic outcomes and QOL. Cochrane and Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) methodology were used to search for prospective and retrospective trials and meta-analyses of adequate quality within the Ovid Medline database between January 1, 2012, and June 15, 2023. These studies informed the expert panel, which rated the appropriateness of various treatments in 6 clinical scenarios through a well-established consensus methodology (modified Delphi). The search process yielded 197 articles that advised voting. Increasing data have shown that nonoperative management (NOM) and primary surgery result in QOL benefits noted over trimodality therapy without detriment to oncologic outcomes. For patients with rectal cancer for whom total mesorectal excision would result in permanent colostomy or inadequate bowel continence, NOM was strongly recommended as usually appropriate. Restaging with tumor response assessment approximately 8 to 12 weeks after completion of radiation therapy/chemoradiation therapy was deemed a necessary component of NOM. The panel recommended active surveillance in the setting of a near-complete or complete response. In the setting of NOM, 54 to 56 Gy in 27 to 31 fractions concurrent with chemotherapy and followed by consolidation chemotherapy was recommended. The panel strongly recommends primary surgery as usually appropriate for a T3N0 high rectal tumor for which low anterior resection and adequate bowel function is possible, with adjuvant chemotherapy considered if N+. Recent data support NOM and primary surgery as important options that should be offered to eligible patients. Considering the complexity of multidisciplinary management, patients should be discussed in a multidisciplinary setting, and therapy should be tailored to individual patient goals/values.

Abstract
A major advance has been made in the management of rectal cancer, with the emergence in 2021 of total neoadjuvant treatment. The main publications from the RAPIDO and PRODIGE-23 trials reported a significant improvement in progression-free survival and the pathological complete response rate. The aim of this review is to synthesize recent data on neoadjuvant treatment of rectal cancer, to explain the long-term results of the RAPIDO and PRODIGE-23 trials, and to put them into perspective, considering current advances in de-escalation strategies. The update of the 5-year survival data from the RAPIDO trial highlights an increased risk of loco-regional relapse, with 11.7% of relapses in the experimental group and 8.1% in the control group, while the update of the PRODIGE-23 trial confirms the benefits of this treatment regimen, with a significant improvement in overall survival. In addition, the results of the OPRA and PROPSPECT trials confirm the benefit of total neoadjuvant treatment with induction chemotherapy, as well as the possibility of surgical de-escalation in the OPRA trial and radiotherapy in the PROSPECT trial. The challenge for the future is to identify patients who require total neoadjuvant treatment with the aim of curative surgery to obtain a cure without local or distant relapse, and those for whom therapeutic de-escalation can be envisaged.

Abstract
AIM The PelvEx Collaborative collates global data on outcomes following exenterative surgery for locally advanced and locally recurrent rectal cancer (LARC and LRRC, respectively). The aim of this study is to report contemporary data from within the collaborative and benchmark it against previous PelvEx publications. METHOD Anonymized data from 45 units that performed pelvic exenteration for LARC or LRRC between 2017 and 2021 were reviewed. The primary endpoints were surgical outcomes, including resection margin status, radicality of surgery, rates of reconstruction and associated morbidity and/or mortality. RESULTS Of 2186 patients who underwent an exenteration for either LARC or LRRC, 1386 (63.4%) had LARC and 800 (36.6%) had LRRC. The proportion of males to females was 1232:954. Median age was 62 years (interquartile range 52-71 years) compared with a median age of 63 in both historical LARC and LRRC cohorts. Compared with the original reported PelvEx data (2004-2014), there has been an increase in negative margin (R0) rates from 79.8% to 84.8% and from 55.4% to 71.7% in the LARC and LRRC cohorts, respectively. Bone resection and flap reconstruction rates have increased accordingly in both cohorts (8.2%-19.6% and 22.6%-32% for LARC and 20.3%-41.9% and 17.4%-32.1% in LRRC, respectively). Despite this, major morbidity has not increased. CONCLUSION In the modern era, patients undergoing pelvic exenteration for advanced rectal cancer are undergoing more radical surgery and are more likely to achieve a negative resection margin (R0) with no increase in major morbidity.

Abstract
Background Recent data have demonstrated that in locally advanced rectal cancer (LARC), a total neoadjuvant therapy (TNT) approach improves compliance with chemotherapy and increases rates of tumor response compared to neoadjuvant chemoradiation (CRT) alone. They further indicate that the optimal sequencing of TNT involves consolidation (rather than induction) chemotherapy to optimize complete response rates. Data, largely from retrospective studies, have also shown that patients with clinical complete response (cCR) after neoadjuvant therapy may be managed safely with the watch and wait approach (WW) instead of preemptive total mesorectal resection (TME). However, the optimal consolidation chemotherapy regimen to achieve cCR has not been established, and a randomized clinical trial has not robustly evaluated cCR as a primary endpoint. Collaborating with a multidisciplinary oncology team and patient groups, we designed this NCI-sponsored study of chemotherapy intensification to address these issues and to drive up cCR rates, to provide opportunity for organ preservation, improve quality of life for patients and improve survival outcomes. Methods In this NCI-sponsored multi-group randomized, seamless phase II/III trial (1:1), up to 760 patients with LARC, T4N0, any T with node positive disease (any T, N+) or T3N0 requiring abdominoperineal resection or coloanal anastomosis and distal margin within 12 cm of anal verge will be enrolled. Stratification factors include tumor stage (T4 vs T1-3), nodal stage (N+ vs N0) and distance from anal verge (0-4; 4-8; 8-12 cm). Patients will be randomized to receive neoadjuvant long course chemoradiation (LCRT) followed by consolidation doublet (mFOLFOX6 or CAPOX) or triplet chemotherapy (mFOLFIRINOX) for 3-4 months. LCRT in both arms involves 4500 cGy in 25 fractions over 5 weeks + 900 cGy boost in 5 fractions with a fluoropyrimidine (capecitabine preferred). Patients will undergo assessment 8-12 (+/- 4) weeks post-TNT completion. The primary endpoint for the phase II portion will compare cCR between treatment arms. A total number of 296 evaluable patients (148 per arm) will provide statistical power of 90.5% to detect an 17% increase in cCR rate, at a one-sided alpha=0.048. The primary endpoint for the phase III portion will compare disease-free survival (DFS) between treatment arms. A total of 285 DFS events will provide 85% power to detect an effect size of hazard ratio 0.70 at a one-sided alpha of 0.025, requiring enrollment of 760 patients (380 per arm). Secondary objectives include time-to event outcomes (overall survival, organ preservation time and time to distant metastasis) and adverse effects. Biospecimens including archival tumor tissue, plasma and buffy coat in EDTA tubes, and serial rectal MRIs will be collected for exploratory correlative research. This study, activated in late 2022, is open across the NCTN and has a current accrual of 312. Support: U10CA180821, U10CA180882, U24 CA196171; https://acknowledgments.alliancefound.org . Discussion Building off of data from modern day rectal cancer trials and patient input from national advocacy groups, we have designed the current trial studying chemotherapy intensification via a consolidation chemotherapy approach with the intent to enhance cCR and DFS rates, increase organ preservation rates, and improve quality of life for patients with rectal cancer.

Abstract
Rectal cancer presents a significant burden globally, often requiring multimodal therapy for locally advanced cases. Long-course chemoradiotherapy (LCRT) and short-course radiotherapy (SCRT) followed by surgery have been conventional neoadjuvant approaches. Recent trials favor LCRT due to improved local control. However, distant tumor recurrence remains a concern, prompting the exploration of total neoadjuvant therapy (TNT) as a comprehensive treatment strategy. Immune checkpoint inhibitors (ICIs) show promise, particularly in mismatch repair-deficient (dMMR) or microsatellite instability-high (MSI-H) tumors, potentially revolutionizing neoadjuvant regimens. Nonoperative management (NOM) represents a viable alternative post-neoadjuvant therapy for selected patients achieving complete clinical response (cCR). Additionally, monitoring minimal residual disease (MRD) using circulating tumor DNA (ctDNA) emerges as a non-invasive method for the assessment of treatment response. This review synthesizes current evidence on TNT, ICIs, NOM, and ctDNA, elucidating their implications for rectal cancer management and highlighting avenues for future research and clinical application.

The efficacy and safety of short-course radiotherapy followed by sequential chemotherapy and Cadonilimab for locally advanced rectal cancer: a protocol of a phase II study. BMC Cancer 2024; 24:501. [PMID: 38641773 PMCID: PMC11031930 DOI: 10.1186/s12885-024-12254-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Accepted: 04/11/2024] [Indexed: 04/21/2024] Open
Abstract
BACKGROUND For patients with locally advanced rectal cancer (LARC), total neoadjuvant therapy (TNT), namely, intensifying preoperative treatment through the integration of radiotherapy and systemic chemotherapy before surgery, was commonly recommended as the standard treatment. However, the risk of distant metastasis at 3 years remained higher than 20%, and the complete response (CR) rate was less than 30%. Several clinical trials had suggested a higher complete response rate when combining single-agent immunotherapy with short-course radiotherapy (SCRT). The CheckMate 142 study had shown encouraging outcomes of dual immunotherapy and seemingly comparable toxicity for CRC compared with single-agent immunotherapy in historical results. Therefore, dual immunotherapy might be more feasible in conjunction with the TNT paradigm of SCRT. We performed a phase II study to investigate whether the addition of a dual immune checkpoint inhibitor bispecific antibody, Cadonilimab, to SCRT combined with chemotherapy might further increase the clinical benefit and prognosis for LARC patients. METHODS This single-arm, multicenter, prospective, phase II study included patients with pathologically confirmed cT3-T4N0 or cT2-4N + rectal adenocarcinoma with an ECOG performance score of 0 or 1. Bispecific antibody immunotherapy was added to SCRT combined with chemotherapy. Patients enrolled would be treated with SCRT (25 Gy in five fractions over 1 week) for the pelvic cavity, followed by 4 cycles of CAPOX or 6 cycles of mFOLFOX and Cadonilimab. The primary endpoint was the CR rate, which was the ratio of the pathological CR rate plus the clinical CR rate. The secondary endpoints included local-regional control, distant metastasis, disease-free survival, overall survival, toxicity profile, quality of life and functional outcome of the rectum. To detect an increase in the complete remission rate from 21.8% to 40% with 80% power, 50 patients were needed. DISCUSSION This study would provide evidence on the efficacy and safety of SCRT plus bispecific antibody immunotherapy combined with chemotherapy as neoadjuvant therapy for patients with LARC, which might be used as a candidate potential therapy in the future. TRIAL REGISTRATION This phase II trial was prospectively registered at ClinicalTrials.gov, under the identifier NCT05794750.

Abstract
Purpose The benefit of intra-operative radiotherapy (IORT) in the treatment of locally advanced rectal cancer (LARC) or locally recurrent rectal cancer (LRRC) lie in its ability to provide high-dose of radiation to limited at-risk volume, thereby eliminating microscopic disease and decreasing toxicity. A comparative study between high-dose-rate (HDR) brachytherapy, named intra-operative brachytherapy (IOBT), and intra-operative electron radiotherapy (IOERT) was performed showing favorable LRFS after IOBT, possibly due to a higher surface dose that is inherent in IOBT technique. The IOERT technique in Catharina Hospital Eindhoven was adapted to increase the surface dose, aiming to improve local control. Post-operative complications due to an increased radiation dose remain the matter of concern. This retrospective study was performed to compare complication rates before and after adapted IOERT dose. Material and methods All patients undergoing surgery with IOERT for LARC or LRRC from September 2019 until July 2023, were considered. Patients selected until August 31, 2021 were included in control cohort (n = 108), and those chosen from September 1, 2021 onwards were included in intervention cohort (n = 92). Perioperative and (major) post-operative complications were classified retrospectively, during admission, at 30 days, and at 90 days. Results In LARC patients, a decrease in post-operative complications was observed (p = 0.009). 19% of LARC patients experienced major post-operative surgical complications, i.e., Clavien-Dindo grade 3b-5, regardless of treatment group. No difference in major 90-day complications was noted (p = 0.142). In LRRC patients, the use of induction chemotherapy decreased from 78% to 29% (p < 0.001), which complicated comparison. However, no difference in major post-operative complications was observed at 30 days (p = 0.222) or 90 days (p = 0.977) after surgery. Conclusions Increased surface dose of IOERT does not seem to lead to an increase in post-operative complications. Further research is needed to evaluate the efficacy of dose adaptation in IOERT to improve local oncological control rates. Routine evaluation of CTCAE scores in follow-up will help uncover possible long-term radiation-induced toxicity.

Abstract
OPINION STATEMENT The introduction of total mesorectal excision into the radical surgery of rectal cancer has significantly improved the oncological outcome with longer survival and lower local recurrence. Traditional treatment modalities of distal rectal cancer, relying on radical surgery, while effective, take their own set of risks, including surgical complications, potential damage to the anus, and surrounding structure owing to the pursuit of thorough resection. The progress of operating methods as well as the integration of systemic therapies and radiotherapy into the peri-operative period, particularly the exciting clinical complete response of patients after neoadjuvant treatment, have paved the way for organ preservation strategy. The non-inferiority oncological outcome of "watch and wait" compared with radical surgery underscores the potential of organ preservation not only to control local recurrence but also to reduce the need for treatments followed by structure destruction, hopefully improving the long-term quality of life. Radical radiotherapy provides another treatment option for patients unwilling or unable to undergo surgery. Organ preservation points out the direction of treatment for distal rectal cancer, while additional researches are needed to answer remaining questions about its optimal use.

Eur J Cardiothorac Surg 2024; 65:ezae110. [PMID: 38530978 DOI: 10.1093/ejcts/ezae110] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/28/2023] [Revised: 03/05/2024] [Accepted: 03/24/2024] [Indexed: 03/28/2024] Open
Abstract
OBJECTIVES Immune checkpoint blockades (ICB) have been proven to improve prognosis of non-small cell lung cancer in the neoadjuvant setting, while whether its perioperative use could bring extra benefit remained unidentified. We aimed to demonstrate the prognostic benefit of perioperative ICB over preoperative-only use and investigate who could benefit from this 'sandwich ICB therapy'. METHODS Patients undergoing neoadjuvant therapy followed by surgery from 2018 to 2022 were retrospectively reviewed, and were divided into 4 groups based on the perioperative regimens: pre-ICB + post-computed tomography (CT), pre-ICB-only, pre-CT + post-ICB and pre-CT-only. Treatment-related adverse events, surgical outcomes, therapeutic response, recurrence-free survival and overall survival were compared. RESULTS Of 214 enrolled patients with preoperative therapy, 108 underwent immunochemotherapy and 106 underwent platinum-based chemotherapy. Compared with preoperative chemotherapy, preoperative immunochemotherapy was demonstrated with significantly higher major pathologic response (57/108 vs 12/106) and pathologic complete response (35/108 vs 4/106) rates with comparable adverse events. Regarding survival, perioperative ICB significantly improved the recurrence-free survival [versus pre-CT-only hazard ratio (HR) 0.15; 95% CI 0.09-0.27; versus pre-ICB-only HR 0.36; 95% CI 0.15-0.88] and overall survival (versus pre-CT-only HR 0.24; 95% CI 0.08-0.68). In patients without major pathologic response, perioperative ICB was observed to decrease the risk of recurrence (HR 0.31; 95% CI 0.11-0.83) compared with preoperative ICB, and was an independent prognostic factor (P < 0.05) for recurrence-free survival. CONCLUSIONS Perioperative ICB showed promising efficacy in improving pathological response and survival outcomes of resectable non-small cell lung cancer. For patients without major pathologic response after resection followed by preoperative ICB, sequential ICB treatment could be considered.

Abstract
We present a case report of a 73-year-old male patient with a complete clinical response following neoadjuvant radiochemotherapy of mid-rectal adenocarcinoma. The patient was initially diagnosed with stage IIIB microsatellite stable mid-rectal adenocarcinoma in February 2017. During restaging in June 2017, which included rectoscopy, endosonography, computed tomography and magnetic resonance imaging, a complete clinical response was observed. After appropriate consultation, a watch-and-wait strategy was chosen. During stringent follow-up every 3 months for the first 3 years and thereafter every 6 months, no recurrence or regrowth was observed. After the fifth year of complete clinical response, we recommended an annual follow-up. As of November 2023, the patient has no signs of recurrence or late toxicity after radiochemotherapy. The omission of resection in patients with locally advanced rectal cancer and the establishment of a watch-and-wait strategy are currently under discussion as possible treatment courses in patients with complete clinical response. Long-term data on watch-and-wait strategies for patients with a complete clinical response in locally advanced rectal cancer are rare. A clear national and international accepted standardization of follow-up programs for patients managed by a watch-and-wait strategy in the long-term is missing. Here, we report the case of a patient who had undergone a follow-up program for more than five years and discuss the current literature. Our case report and literature review highlights that a watch-and-wait strategy does not seem to increase the risk of systemic disease or compromise survival outcomes in selected locally advanced rectal cancer patients. Thus, our case contributes to the growing body of knowledge on personalized and precision medicine for rectal cancer.

Abstract
As the major malignant tumors in the chest, non-small cell lung cancer (NSCLC) and esophageal cancer (EC) bring huge health burden to human beings worldwide. Currently, surgery is still the mainstay for comprehensive treatment for NSCLC and EC, but the prognosis is still poor as the results of cancer recurrence and distant metastasis. Neoadjuvant therapy refers to a single or combined treatment before surgery, aiming to improve the therapeutic effects of the traditional therapies. Unfortunately, the clinical outcomes and effects of neoadjuvant therapy are still controversial due to its apparent advantages and disadvantages, and different patients may respond differentially to the same scheme of neoadjuvant therapy, which makes it urgent and necessary to develop personalized scheme of neoadjuvant therapy for different individuals. Therefore, this review summarizes the novel schemes and strategies of neoadjuvant therapy, which may help to significantly improve of life quality of patients suffering from chest-related malignancies.

Abstract
Background Total neoadjuvant therapy (TNT) is an accepted approach for the management of locally advanced rectal cancer (LARC) and is associated with a decreased risk of development of metastatic disease compared to standard neoadjuvant therapy. However, questions remain regarding surgical outcomes and local control in patients who proceed to surgery, particularly when radiation is given first in the neoadjuvant sequence. We report on our institution's experience with patients who underwent short-course radiation therapy, consolidation chemotherapy, and surgery. Methods We retrospectively reviewed surgical specimen outcomes, postoperative complications, and local/pelvic control in a large cohort of patients with LARC who underwent neoadjuvant therapy incorporating upfront short-course radiation therapy followed by consolidation chemotherapy. Results In our cohort of 83 patients who proceeded to surgery, a complete/near-complete mesorectal specimen was achieved in 90 % of patients. This outcome was not associated with the time interval from completion of radiation to surgery. Postoperative complications were acceptably low. Local control at two years was 93.4 % for all patients- 97.6 % for those with low-risk disease and 90.4 % for high-risk disease. Conclusion Upfront short-course radiation therapy and consolidation chemotherapy is an effective treatment course. Extended interval from completion of short-course radiation therapy did not impact surgical specimen quality.

[PMID: 38041543 DOI: 10.1002/jcu.23623] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/24/2023] [Revised: 10/28/2023] [Accepted: 11/21/2023] [Indexed: 12/03/2023]
Abstract
OBJECTIVE The study aimed to validate the role of 3D-endorectal ultrasonography in prognosis and recurrence for patients with T3-stage rectal cancer by evaluating the preoperative extramural depth of tumor invasion. METHODS In this study, we investigated the medical records of rectal cancer patients who were admitted to Changhai Hospital's Colorectal Surgery Division. The sample group was categorized into three subgroups (T3a, T3b, and T3c) based on the extent of tumor progression (<5 mm, 5-10 mm, and >10 mm) to assess the endorectal ultrasonography diagnostic performance. The 5-year disease-free survival and overall survival were assessed using the Kaplan-Meier method and a log rank test. Cox regression analysis verified the tumor invasion depth's significance as a prognostic predictor, and it was also utilized to evaluate other independent risk variables for recurrence after surgery. RESULTS The study included 72 individuals with low and middle rectal cancer from January 2014 to November 2019. Twenty-two individuals had stage T3a, 22 had stage T3b, and 28 had stage T3c based on preoperative endorectal ultrasonography. Endorectal ultrasonography had 88.0%, 86.8%, and 76.2% overall accuracy for stratifying subgroups, respectively. According to the Kaplan-Meier curve, 5-year OS was 100%, 83.5%, and 92.9% for T3a, T3b, and T3c (p = 0.172), and 5-year disease-free survival was 100%, 80.8%, and 72.9% for T3a, T3b, and T3c, respectively (p = 0.014). A distinct risk factor for 5-year disease-free survival was the degree of tumor infiltration (p = 0.039). CONCLUSION Preoperative T3 stage subdivision allows for categorization of prognosis and survival. Endorectal ultrasonography reports should make explicit declarations of T3a, T3b, and T3c scales.

Timing of Surgery and Social Determinants of Health Related to Pathologic Complete Response after Total Neoadjuvant Therapy for Rectal Adenocarcinoma: Retrospective Study of National Cancer Database. Curr Oncol 2024; 31:1291-1301. [PMID: 38534930 PMCID: PMC10969721 DOI: 10.3390/curroncol31030097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2024] [Revised: 02/26/2024] [Accepted: 02/26/2024] [Indexed: 05/26/2024] Open
Abstract
Total neoadjuvant therapy (TNT) for rectal adenocarcinoma (RAC) involves multi-agent chemotherapy and radiation before definitive surgery. Previous studies of the rest period (time between radiation and surgery) and pathologic complete response (pCR) have produced mixed results. The objective of this study was to evaluate the relationship between the rest period and pCR. This study utilized the National Cancer Database (NCDB) to retrospectively analyze 5997 stage-appropriate RAC cases treated with TNT from 2016 to 2020. The overall pCR rate was 18.6%, with most patients undergoing induction chemotherapy followed by long-course chemoradiation (81.5%). Multivariable logistic regression models revealed a significant non-linear relationship between the rest period and pCR (p = 0.033), with optimal odds at 14.7-15.9 weeks post radiation (odds ratio: 1.49, 95% confidence interval: 1.13-1.98) when compared to 4.0 weeks. Medicaid, distance to the treatment facility, and community education were associated with decreased odds of pCR. Findings highlight the importance of a 15-16-week post-radiation surgery window for achieving pCR in RAC treated with TNT and socioeconomic factors influencing pCR rates. Findings also emphasize the need for clinical trials to incorporate detailed analyses of the rest period and social determinant of health to better guide clinical practice.
