Abstract
Background Placement of an indwelling transanal drainage tube (TDT) to prevent anastomotic leakage (AL) after anterior rectal cancer surgery has become a routine choice for surgeons in the recent years. However, the specific indwelling time of the TDT has not been explored. We performed this meta-analysis and considered the indwelling time a critical factor in re-analyzing the effectiveness of TDT placement in prevention of AL after anterior rectal cancer surgery. Methods Randomized controlled trials (RCTs) and cohort studies which evaluated the effectiveness of TDT in prevention of AL after rectal cancer surgery and considered the indwelling time of TDT were identified using a predesigned search strategy in databases up to November 2022. This meta-analysis was performed to estimate the pooled AL rates (Overall and different AL grades) and reoperation rates at different TDT indwelling times and stoma statuses. Results Three RCTs and 15 cohort studies including 2381 cases with TDT and 2494 cases without TDT were considered eligible for inclusion. Our meta-analysis showed that the indwelling time of TDT for ≥5-days was associated with a significant reduction (TDT vs. Non-TDT) in overall AL (OR=0.46,95% CI 0.34-0.60, p<0.01), grade A+B AL (OR=0.64, 95% CI 0.42-0.97, p=0.03), grade C AL (OR=0.35, 95% CI 0.24-0.53, p<0.01), overall reoperation rate (OR=0.36, 95%CI 0.24-0.53, p<0.01) and that in patients without a prophylactic diverting stoma (DS) (OR=0.24, 95%CI 0.14-0.41, p<0.01). There were no statistically significant differences in any of the abovementioned indicators (p>0.05) when the indwelling time of TDT was less than 5 days. Conclusion Extending the postoperative indwelling time of TDT to 5 days may reduce the overall AL and the need for reoperation in patients without a prophylactic DS.

Wang R, Yan Z. Modular Pelvic Exenteration for Advanced Rectal Cancer in Frozen Pelvis. AMERICAN JOURNAL OF CASE REPORTS 2023; 24:e941684. [PMID: 37968899 PMCID: PMC10660309 DOI: 10.12659/ajcr.941684] [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: 07/05/2023] [Revised: 10/12/2023] [Accepted: 10/04/2023] [Indexed: 11/17/2023]
Abstract
BACKGROUND Surgery for locally advanced rectal cancer with frozen pelvis is challenging. Therefore, we designed the "modular pelvic exenteration" surgical strategy to achieve better radical resection. CASE REPORT A 51-year-old man with rectal cancer refused surgery and received chemotherapy and radiotherapy. He was intolerant to chemotherapy and did not respond well to radiotherapy. With cancer progression, he presented at our hospital with emaciation, fatigue, dysuria, bloody urine, bloody stool, and anal pain. Computed tomography and magnetic resonance imaging revealed the rectal tumor involved multiple adjacent organs and caused rectovesical fistula, bilateral hydronephrosis, hydroureterosis, and local pelvic infection. The rectal tumor was fixed in the pelvic cavity, presenting a frozen pelvis pattern. There was no distant metastasis. As the patient could not tolerate chemotherapy, was unsuitable for immune-check point inhibitor because the tumor had microsatellite stability, and did not respond well to radiotherapy, surgical resection seemed the most suitable treatment option. After the patient's anemia and malnutrition improved, our designed modular pelvic exenteration surgery was performed. In this strategy, we divided pelvic organs and tissues into 4 independent modules. After combining the modules planned to be resected, we delineated the pre-resection margin. By this strategy, the tumor was removed en bloc, with a clear resection margin. The patient was discharged 13 days after the operation, without complications. Follow-up for 24 months revealed no signs of tumor recurrence. CONCLUSIONS For locally advanced rectal cancer with frozen pelvis, the modular pelvic exenteration strategy may help to achieve satisfactory surgical effects in selected patients.

Elevated temperatures and longer durations improve the efficacy of oxaliplatin- and mitomycin C-based hyperthermic intraperitoneal chemotherapy in a confirmed rat model for peritoneal metastasis of colorectal cancer origin. Front Oncol 2023; 13:1122755. [PMID: 37007077 PMCID: PMC10064448 DOI: 10.3389/fonc.2023.1122755] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Accepted: 02/21/2023] [Indexed: 03/19/2023] Open
Abstract
IntroductionIn patients with limited peritoneal metastasis (PM) originating from colorectal cancer, cytoreductive surgery (CRS) followed by hyperthermic intraperitoneal chemotherapy (HIPEC) is a potentially curative treatment option. This combined treatment modality using HIPEC with mitomycin C (MMC) for 90 minutes proved to be superior to systemic chemotherapy alone, but no benefit of adding HIPEC to CRS alone was shown using oxaliplatin-based HIPEC during 30 minutes. We investigated the impact of treatment temperature and duration as relevant HIPEC parameters for these two chemotherapeutic agents in representative preclinical models. The temperature- and duration- dependent efficacy for both oxaliplatin and MMC was evaluated in an in vitro setting and in a representative animal model.MethodsIn 130 WAG/Rij rats, PM were established through i.p. injections of rat CC-531 colon carcinoma cells with a signature similar to the dominant treatment-resistant CMS4 type human colorectal PM. Tumor growth was monitored twice per week using ultrasound, and HIPEC was applied when most tumors were 4-6 mm. A semi-open four-inflow HIPEC setup was used to circulate oxaliplatin or MMC through the peritoneum for 30, 60 or 90 minutes with inflow temperatures of 38°C or 42°C to achieve temperatures in the peritoneum of 37°C or 41°C. Tumors, healthy tissue and blood were collected directly or 48 hours after treatment to assess the platinum uptake, level of apoptosis and proliferation and to determine the healthy tissue toxicity.ResultsIn vitro results show a temperature- and duration- dependent efficacy for both oxaliplatin and MMC in both CC-531 cells and organoids. Temperature distribution throughout the peritoneum of the rats was stable with normothermic and hyperthermic average temperatures in the peritoneum ranging from 36.95-37.63°C and 40.51-41.37°C, respectively. Treatments resulted in minimal body weight decrease (<10%) and only 7/130 rats did not reach the endpoint of 48 hours after treatment.ConclusionsBoth elevated temperatures and longer treatment duration resulted in a higher platinum uptake, significantly increased apoptosis and lower proliferation in PM tumor lesions, without enhanced normal tissue toxicity. Our results demonstrated that oxaliplatin- and MMC-based HIPEC procedures are both temperature- and duration-dependent in an in vivo tumor model.

Lymph node yield less than 12 is not a poor predictor of survival in locally advanced rectal cancer after laparoscopic TME following neoadjuvant chemoradiotherapy. Front Oncol 2022; 12:1080475. [PMID: 36568169 PMCID: PMC9773987 DOI: 10.3389/fonc.2022.1080475] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2022] [Accepted: 11/14/2022] [Indexed: 12/13/2022] Open
Abstract
Purpose Previous studies have confirmed that neoadjuvant chemoradiotherapy (nCRT) may reduce the number of lymph nodes retrieved in rectal cancer. However, it is still controversial whether it is necessary to harvest at least 12 lymph nodes for locally advanced rectal cancer (LARC) patients who underwent nCRT regardless of open or laparoscopic surgery. This study was designed to evaluate the relationship between lymph node yield (LNY) and survival in LARC patients who underwent laparoscopic TME following nCRT. Methods Patients with LARC who underwent nCRT followed by laparoscopic TME were retrospectively analyzed. The relationship between LNY and survival of patients was evaluated, and the related factors affecting LNY were explored. To further eliminate the influence of imbalance of clinicopathological features on prognosis between groups, propensity score matching was conducted. Results A total of 257 consecutive patients were included in our study. The median number of LNY was 10 (7 to 13) in the total cohort. There were 98 (38.1%) patients with 12 or more lymph nodes harvested (LNY ≥12 group), and 159 (61.9%) patients with fewer than 12 lymph nodes retrieved (LNY <12 group). There was nearly no significant difference between the two groups in clinicopathologic characteristics and surgical outcomes except that the age of LNY <12 group was older (P<0.001), and LNY <12 group tended to have more TRG 0 cases (P<0.060). However, after matching, when 87 pairs of patients obtained, the clinicopathological features were almost balanced between the two groups. After a median follow-up of 65 (54 to 75) months, the 5-year OS was 83.9% for the LNY ≥12 group and 83.6% for the LNY <12 group (P=0.893), the 5-year DFS was 78.8% and 73.4%, respectively (P=0.621). Multivariate analysis showed that only patient age, TRG score and ypN stage were independent factors affecting the number of LNY (all P<0.05). However, no association was found between LNY and laparoscopic surgery-related factors. Conclusions For LARC patients who underwent nCRT followed by laparoscopic TME, the number of LNY less than 12 has not been proved to be an adverse predictor for long-term survival. There was no correlation between LNY and laparoscopic surgery-related factors.

Abstract
Purpose The aim of this study was to develop and validate a preoperative scoring system to stratify rectal cancer (RC) patients with different risks of inadequate lymph node examination. Methods A total of 1,375 stage I–III RC patients between 2011 and 2020 from the Second Affiliated Hospital of Harbin Medical University were included in the retrospective study and randomly divided into a development set (n = 688) and a validation set (n = 687). The logistic regression model was used to determine independent factors contributing to lymph node count (LNC) < 12. A preoperative scoring system was constructed based on beta (β) coefficients. The area under the receiver operating curve (AUC) was used to test model discrimination. Results Preoperative significant indicators related to LNC < 12 included age, tumor size, tumor location, and CEA. The AUCs of the scoring system for development and validation sets were 0.694 (95% CI = 0.648–0.741) and 0.666 (95% CI = 0.615–0.716), respectively. Patients who scored 0–2, 3–4, and 5–6 were classified into the low-risk group, medium-risk group, and high-risk group, respectively. Conclusions The preoperative scoring system could identify RC patients with high risk of inadequate lymphadenectomy accurately and further provide a reference to perform preoperative lymph node staining in targeted patients to reduce the difficulty of meeting the 12-node standard, with the purpose of accurate tumor stage and favorable prognosis.

Real-life multidisciplinary treatment for unresectable colorectal cancer liver metastases including hepatic artery infusion with chemo-filtration and liquid biopsy precision oncotherapy: observational cohort study. J Cancer Res Clin Oncol 2020; 146:1273-1290. [PMID: 32088781 PMCID: PMC7142062 DOI: 10.1007/s00432-020-03156-3] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Accepted: 02/13/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND Hepatic artery infusion (HAI) and drug selection by liquid biopsy precision oncotherapy are under investigation for the multidisciplinary treatment of unresectable colorectal liver metastases (CRCLM) in progression after systemic therapy. Here, we compare the safety and efficacy of third-line HAI followed by target therapy with drug regimes selected by liquid biopsy precision oncotherapy to third-line systemic therapy with drug regimes selected partly by tissue biopsy precision oncotherapy, in a retrospective real-life study of 106 unresectable CRCLM patients. METHODS Drug regimens for HAI/target therapy were selected by assessing the sensitivity of purified circulating tumor cell (CTCs) to 5-fluorouracil, carboplatin, cisplatin, oxaliplatin, irinotecan, doxorubicin, mitomycin, raltitrexed, and melphalan in-vitro and by real-time qRT-PCR gene expression assays, and for the Systemic therapy cohort were selected by age, comorbidity, performance status, and absence of RAS mutations. Therapeutic responses, adverse events, and quality of life were evaluated by RECIST 1.1, CTCAE 4.03, and ECOG criteria, respectively, and chemo-filtration performed following HAI to reduce systemic toxic effects. RESULTS HAI/target therapy with drugs selected by liquid biopsy precision oncotherapy (44 patients), resulted in 2.27% CRs, 38.63% PRs, 56.81% SD,s and 2.27% PDs; ECOG 2 to 1 improvement, but no infusion-related technical or vascular complications, or deaths. Systemic therapy (62 patients) resulted in 1.6% CRs, 17.74% PRs, 37.09% SDs, and 45.16% PDs; more grade 1-2 adverse events and 4.84% ECOG 1 to 2 worsening. The median 5 month PFS in the HAI/target therapy cohort was significantly longer than 3 months in the systemic cohort (P < 0.007) and the median 14 month survival in the HAI/target therapy cohort was longer than 8.5 months in the systemic therapy cohort but not statistically significant. Multivariate analysis identified ECOG grade 2 as the most unfavourable survival prognostic factor in both cohorts. CONCLUSIONS HAI plus chemo-filtration followed by target therapy, with drug regimens selected by liquid biopsy precision oncotherapy, is a safe and efficacious alternative therapeutic strategy for unresectable CRCLM in progression after two lines of systemic therapy and should be considered for a multicentre prospective phase III study, to fully confirm this potential.

Abstract
Hypoxia, a common characteristic in solid tumors, is found in phenotypically aggressive cancers that display resistance to typical cancer interventions. Due to its important role in tumor progression, tumor hypoxia has been considered as a primary target for cancer diagnosis and treatment. An advantage of hypoxia-activated nanomedicines is that they are inactive in normoxic cells. In hypoxic tumor tissues and cells, these nanomedicines undergo reduction by activated enzymes (usually through 1 or 2 electron oxidoreductases) to produce cytotoxic substances. In this review, we will focus on approaches to design nanomedicines that take advantage of tumor hypoxia. These approaches include: i) inhibitors of hypoxia-associated signaling pathways; ii) prodrugs activated by hypoxia; iii) nanocarriers responsive to hypoxia, and iv) bacteria mediated hypoxia targeting therapy. These strategies have guided and will continue to guide nanoparticle design in the near future. These strategies have the potential to overcome tumor heterogeneity to improve the efficiency of radiotherapy, chemotherapy and diagnosis.

Abstract
Background Third line innovative systemic treatments and loco-regional chemotherapy by hypoxic pelvic perfusion (HPP) have both been proposed for the treatment of unresectable not responsive recurrent rectal cancer (URRC). In the present study, we have compared the safety and efficacy of HPP/target therapy, using drug regimens selected by liquid biopsy precision oncotherapy, to third-line systemic therapy based on tissue specimens precision oncotherapy. Methods HPP/target therapy regimens were selected based on precision oncotherapy, including assays for chemosensitivity and viability, and qRT-PCR for tumor-related gene expression. In the control group, systemic third-line and further lines of therapy were defined according to clinical and biological parameters. Results From 2007 to 2019, 62 URRC patients were enrolled, comprised of 43 patients in the HPP/target-therapy group and 19 patients in the systemic therapy control group. No HPP related complications were reported and the most common adverse events were skin and bone marrow toxicity. In the HPP/target-therapy group, the ORR was 41.8% whereas in the systemic therapy control group was 15.8%. DCR of the HPP/target-therapy group was significantly improved over the systemic therapy group (P = 0.001), associated with a PFS of 8 vs 4 months (P = 0.009), and OS of 20 vs 8 months (P = 0.046). Conclusions The present data indicate that in URCC patients, the integration of HPP/target-therapy and precision oncotherapy based upon liquid biopsy is as effective and efficacious as third-line treatment in local disease control and, therefore, deserves to be further assessed and compared to conventional systemic treatments in future prospective randomized trials.
