Preoperative Prediction of Long-Term Survival After Surgery in Patients with Resectable Pancreatic Ductal Adenocarcinoma. Ann Surg Oncol 2024:10.1245/s10434-024-15648-4. [PMID: 38926210 DOI: 10.1245/s10434-024-15648-4] [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: 02/29/2024] [Accepted: 06/10/2024] [Indexed: 06/28/2024]
Abstract
BACKGROUND Although some clinical trials have demonstrated the benefits of neoadjuvant therapy for resectable pancreatic ductal adenocarcinoma (PDAC), its optimal candidate has not been clarified. This study aimed to detect predictive prognostic factors for resectable PDAC patients who underwent upfront surgery and identify patient cohorts with long-term survival without neoadjuvant therapy. PATIENTS AND METHODS A total of 232 patients with resectable PDAC who underwent upfront surgery between January 2008 and December 2019 were evaluated. RESULTS The median overall survival (OS) time and 5-year OS rate of resectable PDAC with upfront surgery was 31.5 months and 33.3%, respectively. Multivariate analyses identified tumor diameter in computed tomography (CT) ≤ 19 mm [hazard ratio (HR) 0.40, p < 0.001], span-1 within the normal range (HR 0.54, p = 0.023), prognostic nutritional index (PNI) ≥ 44.31 (HR 0.51, p < 0.001), and lymphocyte-to-monocyte ratio (LMR) ≥ 3.79 (HR 0.51, p < 0.001) as prognostic factors that influence favorable prognoses after upfront surgery. According to the prognostic prediction model based on these four factors, patients with four favorable prognostic factors had a better prognosis with a 5-year OS rate of 82.4% compared to others (p < 0.001). These patients had a high R0 resection rate and a low frequency of tumor recurrence after upfront surgery. CONCLUSIONS We identified patients with long-term survival after upfront surgery by prognostic prediction model consisting of tumor diameter in CT, span-1, PNI, and LMR. Evaluation of anatomical, biological, nutritional, and inflammatory factors may be valuable to introduce an optimal treatment strategy for resectable PDAC.

The survival effect of neoadjuvant therapy and neoadjuvant plus adjuvant therapy on pancreatic ductal adenocarcinoma patients with different TNM stages: a propensity score matching analysis based on the SEER database. Expert Rev Anticancer Ther 2024; 24:467-476. [PMID: 38656796 DOI: 10.1080/14737140.2024.2347513] [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: 02/23/2024] [Accepted: 04/17/2024] [Indexed: 04/26/2024]
Abstract
BACKGROUND Adjuvant therapy (AT) and neoadjuvant therapy (NAT) are standard treatments for pancreatic ductal adenocarcinoma (PDAC) depending on the status of the disease. However, whether AT improves survival after NAT and radical resection in all TNM stages remains unclear. RESEARCH DESIGN AND METHODS We utilized the Surveillance, Epidemiology, and End Results (SEER) database (2010-2019) for PDAC patients who underwent radical surgery and applied Pearson's chi-square test, multivariate and univariate Cox regression, Kaplan-Meier plot, Log-rank tests, and propensity score matching (PSM) for analysis. RESULTS Given PSM after enrolling 13,868 PDAC patients, significant differences in survival were identified between AT and neoadjuvant therapy plus adjuvant therapy (NATAT) (p = 0.023) as well as between NAT and NATAT (p < 0.001). According to the AJCC 8th TNM stage, a survival advantage associated with NATAT was exclusively observed in stage III and IV disease, except for T4N0M0. Some stage IV patients receiving NATAT exhibited comparable survival to their counterparts without metastasis. CONCLUSIONS In this retrospective cohort study, we demonstrated that patients harboring tumors in late TNM stages, including N2 resectable PDAC, might have better survival from NATAT, and that certain patients with M1 disease might still benefit from comprehensive systemic therapy and radical resection.

Abstract
The REDISCOVER guidelines present 34 recommendations for the selection and perioperative care of borderline-resectable (BR-PDAC) and locally advanced ductal adenocarcinoma of the pancreas (LA-PDAC). These guidelines represent a significant shift from previous approaches, prioritizing tumor biology over anatomical features as the primary indication for resection. Condensed herein, they provide a practical management algorithm for clinical practice. However, the guidelines also highlight the need to redefine LA-PDAC to align with modern treatment strategies and to solve some contradictions within the current definition, such as grouping "difficult" and "impossible" to resect tumors together. Furthermore, the REDISCOVER guidelines highlight several areas requiring urgent research. These include the resection of the superior mesenteric artery, the management strategies for patients with LA-PDAC who are fit for surgery but unable to receive multi-agent neoadjuvant chemotherapy, the approach to patients with LA-PDAC who are fit for surgery but demonstrate high serum Ca 19.9 levels even after neoadjuvant treatment, and the optimal timing and number of chemotherapy cycles prior to surgery. Additionally, the role of primary chemoradiotherapy versus chemotherapy alone in LA-PDAC, the timing of surgical resection post-neoadjuvant/primary chemoradiotherapy, the efficacy of ablation therapies, and the management of oligometastasis in patients with LA-PDAC warrant investigation. Given the limited evidence for many issues, refining existing management strategies is imperative. The establishment of the REDISCOVER registry ( https://rediscover.unipi.it/ ) offers promise of a unified research platform to advance understanding and improve the management of BR-PDAC and LA-PDAC.

Abstract
OBJECTIVE The objective of this study was to assess the association of survival with neoadjuvant chemotherapy (NAC) in resectable pancreatic adenocarcinoma (PDAC). BACKGROUND The early control of potential micrometastases and patient selection using NAC has been advocated for patients with PDAC. However, the role of NAC for resectable PDAC remains unclear. METHODS Patients with clinical T1 and T2 PDAC were identified in the National Cancer Database from 2010 to 2017. Kaplan-Meier estimates, and Cox regression models were used to compare survival. To address immortal time bias, landmark analysis was performed. Interactions between preoperative factors and NAC were investigated in subgroup analyses. A propensity score analysis was performed to compare survival between multiagent NAC and upfront surgery. RESULTS In total, 4041 patients were treated with upfront surgery and 1,175 patients were treated with NAC (79.4% multiagent NAC, 20.6% single-agent NAC). Using a landmark time of 6 months after diagnosis, patients treated with multiagent NAC had longer median overall survival compared with upfront surgery and single-agent NAC. (35.8 vs 27.1 vs 27.4 mo). Multiagent NAC was associated with lower mortality rates compared with upfront surgery (adjusted hazard ratio, 0.77; 95% CI, 0.70-0.85), whereas single-agent NAC was not. The association of survival with multiagent NAC were consistent in analyses using the matched data sets. Interaction analysis revealed that the association between multiagent NAC and a lower mortality rate did not significantly differ across age, facility type, tumor location, CA 19-9 levels, and clinical T/N stages. CONCLUSIONS The findings suggest that multiagent NAC followed by resection is associated with improved survival compared with upfront surgery.

Preoperative prediction of early recurrence in resectable pancreatic cancer integrating clinical, radiologic, and CT radiomics features. Cancer Imaging 2024; 24:6. [PMID: 38191489 PMCID: PMC10775464 DOI: 10.1186/s40644-024-00653-3] [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: 07/26/2023] [Accepted: 12/29/2023] [Indexed: 01/10/2024] Open
Abstract
OBJECTIVES To use clinical, radiographic, and CT radiomics features to develop and validate a preoperative prediction model for the early recurrence of pancreatic cancer. METHODS We retrospectively analyzed 190 patients (150 and 40 in the development and test cohort from different centers) with pancreatic cancer who underwent pancreatectomy between January 2018 and June 2021. Radiomics, clinical-radiologic (CR), and clinical-radiologic-radiomics (CRR) models were developed for the prediction of recurrence within 12 months after surgery. Performance was evaluated using the area under the curve (AUC), Brier score, sensitivity, and specificity. RESULTS Early recurrence occurred in 36.7% and 42.5% of the development and test cohorts, respectively (P = 0.62). The features for the CR model included carbohydrate antigen 19-9 > 500 U/mL (odds ratio [OR], 3.60; P = 0.01), abutment to the portal and/or superior mesenteric vein (OR, 2.54; P = 0.054), and adjacent organ invasion (OR, 2.91; P = 0.03). The CRR model demonstrated significantly higher AUCs than the radiomics model in the internal (0.77 vs. 0.73; P = 0.048) and external (0.83 vs. 0.69; P = 0.038) validations. Although we found no significant difference between AUCs of the CR and CRR models (0.83 vs. 0.76; P = 0.17), CRR models showed more balanced sensitivity and specificity (0.65 and 0.87) than CR model (0.41 and 0.91) in the test cohort. CONCLUSIONS The CRR model outperformed the radiomics and CR models in predicting the early recurrence of pancreatic cancer, providing valuable information for risk stratification and treatment guidance.

Feasibility of laparoscopic versus open pancreatoduodenectomy following neoadjuvant chemotherapy for borderline resectable pancreatic cancer: a retrospective cohort study. World J Surg Oncol 2024; 22:1. [PMID: 38169384 PMCID: PMC10759588 DOI: 10.1186/s12957-023-03277-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Accepted: 12/09/2023] [Indexed: 01/05/2024] Open
Abstract
BACKGROUND There is no evidence supporting the feasibility of laparoscopic pancreaticoduodenectomy (LPD) compared to open pancreatoduodenectomy (OPD) following neoadjuvant chemotherapy (NACT) for pancreatic ductal adenocarcinoma (PDAC). METHODS The clinical data of consecutive patients with borderline resectable PDAC who received NACT and underwent either LPD or OPD between January 2020 and December 2022 at Fudan University Shanghai Cancer Center was prospectively collected and retrospectively analyzed. RESULTS The analysis included 57 patients in the OPD group and 20 in the LPD group. Following NACT, the LPD group exhibited a higher median CA19-9 decrease rate compared to the OPD group (85.3% vs. 66.9%, P = 0.042). Furthermore, 3 anatomically borderline PDACs in the LPD group and 5 in the OPD group were downstaged into resectable status (30.0% vs. 12.3%, P = 0.069). According to RECIST criteria, 51 (66.2%) patients in the entire cohort were evaluated as having stable disease. The median operation time for the LPD group was longer than the OPD group (419 vs. 325 min, P < 0.001), while the venous resection rate was 35.0% vs. 43.9%, respectively (P = 0.489). There was no difference in the number of retrieved lymph nodes, with a median number of 18.5 in the LPD group and 22 in the OPD group, and the R1 margin rate (15.0% vs. 12.3%) was also comparable. The incidence of Clavien-Dindo complications (35.0% vs. 66.7%, P = 0.018) was lower in the LPD group compared to the OPD group. Multivariable regression analysis revealed that a tumor diameter > 3 cm before NACT (HR 2.185) and poor tumor differentiation (HR 1.805) were independent risk factors for recurrence-free survival, and a decrease rate of CA19-9 > 70% (OR 0.309) was a protective factor for early tumor recurrence and overall survival. CONCLUSIONS LPD for PDAC following NACT is feasible and oncologically equivalent to OPD. Effective control of CA19-9 levels is beneficial in reducing early tumor recurrence and improving overall survival.

Abstract
Pancreatic cancer is a malignant disease with a dismal prognosis. While neoadjuvant therapy has shown promise in the treatment of pancreatic cancer, its role remains a subject of controversy among physicians. We aimed to evaluate the benefits of neoadjuvant therapy in patients with resectable and borderline resectable pancreatic cancer. Eligible studies were identified from MEDLINE, Embase, Cochrane Library, and Web of Science. Studies comparing neoadjuvant therapy with upfront surgery (with or without adjuvant therapy) in resectable and borderline resectable pancreatic cancer were included. The primary endpoint assessed was overall survival. A total of 10,022 studies were identified, and the meta-analysis finally enrolled 50 revealed studies. The meta-analysis suggested that neoadjuvant therapy significantly improved the overall survival (HR 0.74, p < 0.001) and recurrence-free survival (HR 0.75, p = 0.006) compared to the upfront surgery approach. Furthermore, neoadjuvant therapy leads to favorable postoperative outcomes, with an enhanced R0 resection rate (OR 1.90, p < 0.001) and reduced lymph node metastasis (OR 0.36, p < 0.001) and perineural invasion (OR 0.42, p < 0.001), although it is associated with a reduced resection rate (OR 0.42, p < 0.001). In addition, patients treated with neoadjuvant therapy experience superior survival benefits compared to those undergoing adjuvant therapy (HR 0.87, p = 0.019). These results are further corroborated by the subgroup analysis of randomized controlled trials. Neoadjuvant therapy has the potential to provide survival benefits and improve postoperative long-term outcomes for patients with resectable and borderline resectable pancreatic cancer. However, to validate and reinforce these findings, further well-designed and large trials are required.

Abstract
Pancreatic cancer is one of the leading causes for cancer-related deaths in the United States. Majority of patients present with unresectable or metastatic disease. For those that present with localized disease, a multidisciplinary approach is necessary to maximize survival and optimize outcomes. The quality and safety of surgery for pancreatic cancer have improved in recent years with increasing adoption of minimally invasive techniques and surgical adjuncts. Systemic chemotherapy has also evolved to impact survival. It is now increasingly being utilized in the neoadjuvant setting, often with concomitant radiation. Increased utilization of genomic testing in metastatic pancreatic cancer has led to better understanding of their biology, thereby allowing clinicians to consider potential targeted therapies. Similarly, targeted agents such as PARP inhibitors and immune checkpoint- inhibitors have emerged with promising results. In summary, pancreatic cancer remains a disease with poor long-term survival. However, recent developments have led to improved outcomes and have changed practice in the past decade. This review summarizes current practices in pancreatic cancer treatment and the milestones that brought us to where we are today, along with emerging therapies.

Utility of contrast-enhanced harmonic endoscopic ultrasonography for prediction of pathological response after neoadjuvant chemotherapy in patients with pancreatic cancer. Pancreatology 2023; 23:1014-1019. [PMID: 37926599 DOI: 10.1016/j.pan.2023.10.016] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/05/2023] [Revised: 09/27/2023] [Accepted: 10/22/2023] [Indexed: 11/07/2023]
Abstract
OBJECTIVES Contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) plays an important role in the diagnosis of pancreatic lesions. The aim of this study was to evaluate whether CH-EUS is useful for predicting the treatment efficacy of neoadjuvant chemotherapy (NAC) determined by pathological response. METHODS Patients who underwent CH-EUS before chemotherapy and surgical resection were divided into two groups according to poor (group-P) or rich tumor vascularity (group-R) determined by enhancement pattern on early- and late-phase CH-EUS. The pathological response to chemotherapy was categorized according to Evans' classification. Pathological analysis showing tumor cell destruction (>50 %) defined a good response. RESULTS Early-phase CH-EUS classified 44 patients into group-R and 50 into group-P, whereas late-phase CH-EUS classified 10 into group-R and 84 into group-P. Early-phase CH-EUS classification resulted in significantly higher numbers of patients with a good response in the rich group (n = 19) than in the poor group (n = 4; P = 0.0015). Multivariate analysis showed that assignment to the rich group was the strongest independent factor associated with chemosensitivity (P = 0.006, hazard ratio = 5.66, 95 % confidence interval: 1.17-19.27). In resectable patients, the enhancement pattern was the only independent factor associated with chemosensitivity (group-P vs. group-R, P = 0.003; HR [95 % CI], 14.59 [1.38-154.38]). Late-phase CH-EUS did not reveal a significant difference between group-P and group-R. CONCLUSIONS Evaluation of vascular pattern on CH-EUS could be useful for predicting the efficacy of NAC in patients with pancreatic cancer. The enhancement pattern on CH-EUS could be a one of the useful features for determining NAC indications in resectable pancreatic cancer patients.

Abstract
Background Nab-paclitaxel plus gemcitabine is a standard treatment for metastatic/locally advanced pancreatic cancer. The effectiveness of neoadjuvant therapy with nab-paclitaxel plus gemcitabine (GnP-NAT) in patients with borderline resectable pancreatic cancer (BRPC) remains unclear. Patients and Methods This single-arm phase II trial included 61 patients with BRPC that were treated with two cycles of GnP-NAT, (nab-paclitaxel 125 mg/m2 and gemcitabine 1000 mg/m2), on days 1, 8, and 15 over a 4-week period, which comprised one cycle. The primary endpoint was overall survival time. In the absence of disease progression, patients underwent planned pancreatectomy. Results Median overall survival, the primary endpoint, was 25.2 months, and the median recurrence-free survival was 12.3 months. The overall rate of grade 3/4 events was 73.8%. One patient, who had a history of radiation therapy for past esophageal cancer, died from exacerbation via pneumonia. The overall resection rate was 73.8% (n = 45), and the R0 resection rate was 63.9% (n = 39). Overall, postoperative complications were found in 19 patients (42%) with 24 events, and nine patients (20%) with nine events ≥ grade IIIa, based on Dindo's classification. Conclusions This protocol treatment is thought to be a feasible, safe, and promising treatment regimen, but we caution against its use in patients with a history of interstitial lung disease and/or prior pulmonary irradiation. The survival data from this study suggest the need for further investigations of GnP-NAT efficacy in patients with BRPC, as well as prospective evaluation of adverse events.

Abstract
BACKGROUND/PURPOSE The benefits of anti-reflux metal stents, used for treating biliary obstruction in patients receiving neoadjuvant chemotherapy (NAC) for pancreatic cancer, are yet unknown. Herein, the safety and efficacy of the novel duckbill-type anti-reflux metal stent (D-ARMS) were prospectively evaluated for biliary drainage. Additionally, the incidence of recurrent biliary obstruction (RBO) after placement of D-ARMS vs conventional covered self-expandable metal stents (CCSEMSs) was retrospectively compared. METHODS Patients who received D-ARMS (n = 33) for treatment of distal biliary obstruction before NAC between September 2019 and January 2021 and those that received CCSEMSs (n = 38) between January 2013 and August 2019 were included in the historical control group. Technical and clinical successes, rate of RBO, and cumulative incidence of RBO were compared between the two groups. RESULTS The technical success rate was 100% for both the D-ARMS and CCSEMS groups, and the clinical success rate were not significantly different (93.9% and 89.5%, respectively; P = .68). In the multivariate analysis, D-ARMS was identified as the independent factor for cumulative incidence of RBO (P = .03). The cumulative incidence of RBO was significantly lower in the D-ARMS group than that in the CCSEMS group (P = .04). CONCLUSIONS D-ARMS is safe and effective for patients receiving NAC.

Abstract
PURPOSE To clarify the relationship between extracellular volume (ECV) measured by dual-energy CT (DECT) and efficacy of preoperative neoadjuvant chemotherapy (NAC) in patients with pancreatic ductal adenocarcinoma (PDAC), as compared with single-energy CT (SECT). METHODS We enrolled 67 patients with PDAC who underwent dynamic contrast-enhanced CT with a dual-energy CT system prior to NAC. Attenuation values were measured on unenhanced and the equilibrium-phase 120-kVp equivalent CT images for PDAC and the aorta. ΔHU-tumor, ΔHU-tumor/ΔHU-aorta, and SECT-ECV were calculated. Iodine densities of the tumor and aorta were measured in the equilibrium phase, and DECT-ECV of the tumor was calculated. Response to NAC was evaluated and the correlation between imaging parameters and response to NAC was statistically assessed. RESULTS Tumor DECT-ECVs were significantly lower in the response group (n = 7) than in the non-response group (n = 60), with most significant difference (p = 0.0104). DECT-ECV showed highest diagnostic value with an Az value of 0.798. When using the optimal cut off value of DECT-ECV (<26.0 %), sensitivity, specificity, accuracy, positive predictive value, and negative value for predicting response group were 71.4 %, 85.0 %, 83.6 %, 35.7 % and 96.2 %, respectively. CONCLUSION PDAC with lower DECT-ECV can potentially show better response to NAC. DECT-ECV might be a useful biomarker for predicting response to NAC in patients with PDAC.

Abstract
Importance The total number of patients with pancreatic ductal adenocarcinoma (PDAC) who receive neoadjuvant chemotherapy (NAC) is increasing. However, the added role of adjuvant chemotherapy (AC) in these patients remains unknown. Objective To evaluate the association of AC with overall survival (OS) in patients with PDAC who received multiagent NAC followed by curative-intent surgery. Design, Setting, and Participants This retrospective, matched-cohort study used data from the National Cancer Database and included patients with PDAC diagnosed between 2010 and 2018. The study included patients at least 18 years of age who received multiagent NAC followed by surgical resection and had available records of the pathological findings. Patients were excluded if they had clinical or pathological stage IV disease or died within 90 days of their operation. Exposures All included patients received NAC and underwent resection for primary PDAC. Some patients received adjuvant chemotherapy. Main Outcomes and Measures The main outcome was the OS of patients who received AC (AC group) vs those who did not (non-AC group). Interactions between pathological findings and AC were investigated in separate multivariable Cox regression models. Results In total, 1132 patients (mean [SD] age, 63.5 [9.4] years; 577 [50.1%] male; 970 [85.7%] White) were included, 640 patients in the non-AC group and 492 patients in the AC group. After being matched by propensity score according to demographic and pathological characteristics, 444 patients remained in each group. The multivariable Cox regression model adjusted for all covariates revealed an association between AC and improved survival (hazard ratio, 0.71; 95% CI, 0.59-0.85; P < .001). Subgroup interaction analysis revealed that AC was significantly associated with better OS (26.6 vs 21.2 months; P = .002), but the benefit varied by age, pathological T category, and tumor differentiation. Of note, AC was associated with better survival in patients with any pathological N category and positive margin status. Conclusions and Relevance In this cohort study, AC following multiagent NAC and resection in patients with PDAC was associated with significant survival benefit compared with that in patients who did not receive AC. These findings suggest that patients with aggressive tumors may benefit from AC to achieve prolonged survival, even after multiagent NAC and curative-intent resection.

Abstract
Objectives Neoadjuvant therapy followed by radical resection improves the borderline-resectable pancreatic cancer (BRPC) prognosis; however, the optimal therapeutic regimen remains unclear. Gemcitabine plus nab-paclitaxel (GnP) showed a high anti-tumor effect in primary lesions in a prospective study for metastatic disease. However, evidence concerning its feasibility is still lacking in patients with BRPC. We therefore evaluated the tolerability of neoadjuvant GnP (NAC-GnP) for BRPC. Methods This single-center prospective study evaluated 10 patients with BRPC who were treated with two cycles of NAC-GnP. The primary endpoint was feasibility for NAC-GnP. Treatment feasibility was defined as a successful outcome in at least eight patients. Results Ten patients who had BRPC in contact with the celiac artery (n=5), superior mesenteric artery (n=3), or hepatic artery (n=2) were enrolled. The median age was 75 (range, 40-82) years old. Grade 3 anorexia and grade 2 pneumonia occurred in one patient each, so treatment was feasible in eight patients. The median primary tumor reduction and response rates were 33% (range, 0-68%) and 60%, respectively. Six of eight patients who had abnormal CA19-9 levels at the time of enrolment showed a decrease in CA19-9 levels, with a median decrease of 72%. Five patients underwent radical resection, including R0 resection in four. Postoperative grade IIIa Clavien-Dindo complications occurred in one patient (upper gastrointestinal bleeding and pancreatic fistula). Conclusion Two-cycle NAC-GnP is a feasible treatment for patients with BRPC. Further studies on NAC-GnP in patients with BRPC are warranted.

A Prospective Multicenter Phase II Trial of Neoadjuvant Chemotherapy with Gemcitabine Plus Nab-Paclitaxel for Borderline Resectable Pancreatic Cancer with Arterial Involvement. Ann Surg Oncol 2023; 30:193-202. [PMID: 36207481 DOI: 10.1245/s10434-022-12566-1] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2022] [Accepted: 08/28/2022] [Indexed: 12/13/2022]
Abstract
BACKGROUND Only two clinical trials have shown the effects of neoadjuvant treatment for borderline resectable pancreatic cancer with arterial involvement (BRPC-A). Here, we aimed to analyze the efficacy and safety of neoadjuvant gemcitabine plus nab-paclitaxel (GnP) for BRPC-A. PATIENTS AND METHODS A prospective, single-arm, multicenter phase II trial was conducted. Patients who were radiologically and histologically diagnosed with BRPC-A were enrolled. A central review was conducted to confirm the presence of BRPC-A. Patients received two to four cycles of GnP before surgery. The primary endpoint of the study was the R0 resection rate. Overall survival (OS) was evaluated in an ancillary study. RESULTS Thirty-five patients were enrolled, of whom 33 were subjected to central review and 28 were confirmed to have BRPC-A. All eligible patients with BRPC-A received neoadjuvant GnP. Nineteen patients underwent pancreatic resections. Postoperative complications of Clavien-Dindo IIIa or lower were observed in 11 patients. No treatment-related mortalities were observed. R0 resection was achieved in 17 patients (89%); the R0 resection rate was 61% in eligible patients. One patient underwent curative resection after termination of the treatment protocol, resulting in an overall R0 resection rate of 64%. The median overall survival (OS) and 2-year OS rate were 24.9 months [95% confidence interval (CI) 19.0 months to not estimatable] and 53.6%, respectively. OS in patients with BRPC-A who achieved overall R0 resection was significantly longer than that in the other patients (p = 0.0255). CONCLUSIONS Neoadjuvant GnP is a safe and effective strategy for BRPC-A, providing a chance for curative resection and improved survival.

Abstract
OBJECTIVES The role of concomitant chemoradiotherapy or radiotherapy (RT) after induction chemotherapy (IC) in borderline resectable and locally advanced pancreatic ductal adenocarcinoma is debatable. This systematic review aimed to explore this. METHODS We searched PubMed, MEDLINE, EMBASE, and Cochrane database. Studies were selected reporting outcomes on resection rate, R0 resection, pathological response, radiological response, progression-free survival, overall survival, local control, morbidity, and mortality. RESULTS The search resulted in 6635 articles. After 2 rounds of screening, 34 publications were selected. We found 3 randomized controlled studies and 1 prospective cohort study, and the rest were retrospective studies. There is consistent evidence that addition of concomitant chemoradiotherapy or RT after IC improves pathological response and local control. There are conflicting results in terms of other outcomes. CONCLUSIONS Concomitant chemoradiotherapy or RT after IC improves local control and pathological response in borderline resectable and locally advanced pancreatic ductal adenocarcinoma. The role of modern RT in improving other outcome requires further research.

HPB (Oxford) 2023; 25:100-108. [PMID: 36280425 DOI: 10.1016/j.hpb.2022.09.012] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2021] [Revised: 07/09/2022] [Accepted: 09/28/2022] [Indexed: 12/12/2022]
Abstract
BACKGROUND Neoadjuvant chemotherapy (NAC) is widely used to treat borderline resectable pancreatic cancer. This study aimed to evaluate the serum carbohydrate antigen (CA)19-9 response, in association with survival, after four cycles of NAC-gemcitabine plus nab-paclitaxel. METHODS From 2015 to 2018, patients with borderline resectable pancreatic cancer were treated with NAC. Patients were stratified into two groups after excluding CA19-9 non-secretor: Group L (CA19-9 ≥2 and ≤500 U/mL) and Group H (CA19-9 >500 U/mL). The CA19-9 decrease during NAC was evaluated as a response of NAC and was assessed in association with survival concomitant with other prognosis factors. RESULTS Eighty-seven patients were evaluated (Group L: n = 43, Group H: n = 44). In intention-to-treat-based analysis, Group L exhibited significantly better progression-free survival (PFS) than Group H (median PFS: 24 vs 14months). In resection cohort, no correlation was detected between the CA19-9 decrease and survival in Group L. In Group H, the CA19-9 decrease ≤80% was associated with unfavorable survival in multivariate analysis [Hazard ratio: 4.738 (P = 0.007)]. CONCLUSION In patients with pre-treatment CA19-9 >500 U/mL, the CA19-9 decrease ≤80% was strongly associated with poor survival and new strategy should be reconsidered for these patients.

Abstract
To examine the potential benefits and adverse events of neoadjuvant Chemoradiotherapy (CRT) versus upfront surgery in pancreatic cancer (PC) patients. Extensive librarian-led literature searches were conducted on PubMed, Web-of-Science, Scopus, Google Scholar, the Cochrane Central Library and Embase. The primary outcomes were resectability, adverse events, pathological and survival outcomes. Five studies, including 437 participants, were analyzed. Upfront surgery had a significantly higher resectability among PC patients than neoadjuvant CRT group (Odds ratio = -0.11, 95% CI = -0.19-0.02, P = 0.01). The neoadjuvant CRT group had a comparatively higher Ro resection rate (OR = 3.38, 95% CI = 2.03-5.62, P < 0.01), fewer severe adverse events(OR = 0.56, 95% CI = 0.34-0.92, P = 0.02), lower positive LN rate(OR = 0.18, 95% CI = 0.11-0.31, P < 0.01) and higher 2-year OS(OR = 1.60, 95% CI = 1.02-2.52, P = 0.04) among PC patients than control group. There was no significant difference between neoadjuvant CRT and upfront surgery among PC patients on postoperative complications(OR = 1.49, 95% CI = 0.86-2.57, P = 0.16), metastasis rate(OR = 1.32, 95% CI = 0.42-4.18, P = 0.64) and 1-year OS(OR = 1.30, 95% CI = 0.85-1.98, P = 0.22). This systematic review confirmed the status of neoadjuvant CRT in the PC treatment. The neoadjuvant CRT could increase the R0 resection rate, which was important to the survival and life quality of patients. The specific choice of various neoadjuvant CRT therapy needs to be further studied. Individualized neoadjuvant therapy should be suitable for each patient, and patients with PC are best managed by a multidisciplinary team.

Possibility of Neoadjuvant Treatment for Radiologically Judged Resectable Pancreatic Cancer. J Clin Med 2022; 11:jcm11226792.

Abstract
Survival remains poor even after resection of pancreatic cancer and the postoperative recurrence rate is extremely high. Thus, neoadjuvant treatment may improve outcomes for resectable pancreatic cancer (RPC). This study evaluated the efficacy of neoadjuvant therapy for radiologically judged RPC. A prospectively maintained institutional database was reviewed to identify patients who underwent potentially curative resection of radiologically judged RPC. Patient characteristics and intermediate-term outcomes were compared between groups that received neoadjuvant treatment or upfront surgery (UFS). We identified 353 eligible patients, including 55 patients who received neoadjuvant chemoradiotherapy (CRT group), 53 patients who received neoadjuvant gemcitabine plus nab-paclitaxel (GnP group), and 245 patients who underwent UFS (UFS group). The cumulative rates of pancreatic cancer recurrence at 2 years after pancreatic surgery were 49.5% in the UFS, 48.1% in the CRT group, and 52.7% in the GnP group. The recurrence rate tended to be improved after neoadjuvant treatment, although the difference was not significant at this follow-up point. While the clinical TNM classifications were noticeably different from the final pathological findings, the clinical and pathological TNM classifications were more similar in the groups that underwent neoadjuvant treatment. Neoadjuvant treatment can help identify good surgical candidates and avoid unnecessary laparotomy. Our results also suggest that neoadjuvant therapy might help improve the preoperative diagnostic accuracy for patients with RPC.

Evaluation of local recurrence after pancreaticoduodenectomy for borderline resectable pancreatic head cancer with neoadjuvant chemotherapy: Can the resection level change after chemotherapy? Surgery 2022; 173:1220-1228.

Abstract
BACKGROUND Neoadjuvant treatment has significant survival benefits for patients with pancreatic cancer. However, local recurrence remains a serious issue, even after neoadjuvant treatment. This study investigated local recurrence after pancreaticoduodenectomy and determined the optimal resection level after neoadjuvant treatment. METHODS This retrospective study analyzed consecutive patients who underwent pancreaticoduodenectomy for borderline resectable pancreatic cancer after 4 cycles of neoadjuvant treatment-gemcitabine plus nab-paclitaxel between April 2015 and March 2020. Patients with borderline resectable-artery pancreatic cancer were classified according to the dissection level around the artery: level 3 group, hemi-, or whole circumferential arterial nerve plexus was dissected; and level 2 group, the nerve plexus was preserved. RESULTS Fifty-six patients with borderline resectable-artery pancreatic cancer underwent pancreaticoduodenectomy after neoadjuvant treatment (level 3 group, n = 40; level 2 group, n = 16). The resection level in the level 2 group was changed based on post-neoadjuvant treatment computed tomography images or intraoperative frozen section diagnosis. The overall and local recurrence rates were significantly higher in the level 2 group than in the level 3 group (overall recurrence, 93.8% vs 70.0%; P = .037) (local recurrence, 50.0% vs 5.0%; P < .001). Ten patients experienced local recurrence, of which 8 belonged to the level 2 group. Among them, 4 patients were confirmed as cancer-negative by surgical margin analysis or intraoperative frozen section diagnosis but experienced recurrence around the arteries. CONCLUSION For treating borderline resectable-artery pancreatic cancer, changing the resection level based on post-neoadjuvant treatment computed tomography images increased the risk of local recurrence. All patients with borderline resectable-artery should undergo level 3 dissection, regardless of the response to neoadjuvant treatment.

Abstract
BACKGROUND Multiple studies have demonstrated that neoadjuvant chemotherapy (NACT) can prolong the overall survival of pancreatic ductal adenocarcinoma (PDAC) patients. However, most studies have focused on open surgery following NACT.
AIM To investigate the efficacy and safety of laparoscopic radical resection following NACT for PDAC.
METHODS We retrospectively analyzed the clinical data of 15 patients with pathologically confirmed PDAC who received NACT followed by laparoscopic radical surgery in our hospital from December 2019 to April 2022. All patients underwent abdominal contrast-enhanced computed tomography (CT) and positron emission tomography-CT before surgery to accurately assess tumor stage and exclude distant metastasis.
RESULTS All 15 patients with pancreatic cancer were successfully converted to surgical resection after NACT, including 8 patients with pancreatic head cancer and 7 patients with pancreatic body and tail cancer. Among them, 13 patients received the nab-paclitaxel plus gemcitabine regimen (gemcitabine 1000 mg/m2 plus nab-paclitaxel 125 mg/m2 on days 1, 8, and 15 every 4 wk) and 2 patients received the modified FOLFIRINOX regimen (intravenous oxaliplatin 68 mg/m2, irinotecan 135 mg/m2, and leucovorin 400 mg/m2 on day 1 and fluorouracil 400 mg/m2 on day 1, followed by 46-h continuous infusion of fluorouracil 2400 mg/m2). After each treatment cycle, abdominal CT, tumor markers, and circulating tumor cell counts were reviewed to evaluate the treatment efficacy. All 15 patients achieved partial remission. The surgical procedures included laparoscopic pancreaticoduodenectomy (LPD, n = 8) and laparoscopic radical antegrade modular pancreatosplenectomy (L-RAMPS, n = 7). None of them were converted to a laparotomy. One patient with pancreatic head carcinoma was found to have portal vein involvement during the operation, and LPD combined with vascular resection and reconstruction was performed. The amount of blood loss and operation times of L-RAMPS vs LPD were 435.71 ± 32.37 mL vs 343.75 ± 145.01 mL and 272.52 ± 49.14 min vs 444.38 ± 68.63 min, respectively. The number of dissected lymph nodes was 16.87 ± 4.10, and 3 patients had positive lymph nodes. One patient developed grade B postoperative pancreatic fistula (POPF) after L-RAMPS, and one patient experienced jaundice after LPD. None of the patients died after surgery. As of April 2022, progressive disease was noted in 4 patients, 2 patients had liver metastasis, and one had both liver metastasis and lymph node metastasis and died during the follow-up period.
CONCLUSION Laparoscopic radical resection of PDAC after NACT is safe and effective if it is performed by a surgeon with rich experience in LPD and in a large center of pancreatic surgery.

Abstract
Simple Summary Borderline resectable pancreatic cancer (BRPC) has been primarily indicated for neoadjuvant treatment (NAT) in the last decade. This study is the updated meta-analysis for only patients with BRPC including recent NAT regimens such as FOLFIRINOX. The OS, R0 resection rate, and node-negativity rate was improved in NAT group compared with upfront surgery. Providing high-quality evidence is important to standardize the treatment protocol and help physicians decide the appropriate pancreatic cancer treatment. Abstract Neoadjuvant treatment (NAT) followed by surgery is the primary treatment for borderline resectable pancreatic cancer (BRPC). However, there is limited high-level evidence supporting the efficacy of NAT in BRPC. PubMed was searched to identify studies that compared the survival between BRPC patients who underwent NAT and those who underwent upfront surgery (UFS). The overall survival (OS) was compared using intention-to-treat (ITT) analysis. A total of 1204 publications were identified, and 19 publications with 21 data sets (2906 patients; NAT, 1516; UFS, 1390) were analyzed. Two randomized controlled trials and two prospective studies were included. Thirteen studies performed an ITT analysis, while six presented the data of resected patients. The NAT group had significantly better OS than the UFS group in the ITT analyses (HR: 0.63, 95% CI = 0.53–0.76) and resected patients (HR: 0.68, 95% CI = 0.60–0.78). Neoadjuvant chemotherapy with gemcitabine or S-1 and FOLFIRINOX improved the survival outcomes. Among the resected patients, the R0 resection and node-negativity rates were significantly higher in the NAT group. NAT improved the OS, R0 resection rate, and node-negativity rate compared with UFS. Standardizing treatment regimens based on high-quality evidence is fundamental for developing an optimal protocol.

Abstract
BACKGROUND The 2020 National Comprehensive Cancer Network guidelines recommend neoadjuvant FOLFIRINOX or neoadjuvant gemcitabine plus nab-paclitaxel (G-nP) for borderline resectable/locally advanced pancreatic ductal adenocarcinoma (BR/LA PDAC). AIM The purpose of our study was to compare treatment outcomes, toxicity profiles, costs, and quality-of-life measures between these two treatments to further inform clinical decision-making. METHODS AND RESULTS We developed a decision-analytic mathematical model to compare the total cost and health outcomes of neoadjuvant FOLFIRINOX against G-nP over 12 years. The model inputs were estimated using clinical trial data and published literature. The primary endpoint was incremental cost-effectiveness ratios (ICERs) with a willingness-to-pay threshold of $100 000 per quality-adjusted-life-year (QALY). Secondary endpoints included overall (OS) and progression-free survival (PFS), total cost of care, QALYs, PDAC resection rate, and monthly treatment-related adverse events (TRAE) costs (USD). FOLFIRINOX was the cost-effective strategy, with an ICER of $60856.47 per QALY when compared to G-nP. G-nP had an ICER of $44639.71 per QALY when compared to natural history. For clinical outcomes, more patients underwent an "R0" resection with FOLFIRINOX compared to G-nP (84.9 vs. 81.0%), but FOLFIRINOX had higher TRAE costs than G-nP ($10905.19 vs. $4894.11). A one-way sensitivity analysis found that the ICER of FOLFIRINOX exceeded the threshold when TRAE costs were higher or PDAC recurrence rates were lower. CONCLUSION Our modeling analysis suggests that FOLFIRNOX is the cost-effective treatment compared to G-nP for BR/LA PDAC despite having a higher cost of total care due to TRAE costs. Trial data with sufficient follow-up are needed to confirm our findings.

[PMID: 35785193 PMCID: PMC9245892 DOI: 10.3389/fonc.2022.828223] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2021] [Accepted: 05/09/2022] [Indexed: 11/15/2022] Open
Abstract
The incidence of pancreatic ductal adenocarcinoma (PDAC) has been on the rise in recent years; however, its clinical diagnosis and treatment remain challenging. Although surgical resection remains the only chance for long-term patient survival, the likelihood of initial resectability is no higher than 20%. Neoadjuvant therapy (NAT) in PDAC aims to transform the proportion of inoperable PDACs into operable cases and reduce the likelihood of recurrence to improve overall survival. Ongoing phase 3 clinical trial aims to validate the role of NAT in PDAC therapy, including prolongation of survival, increased R0 resection, and a higher proportion of negative lymph nodes. Controversies surrounding the role of NAT in PDAC treatment include applicability to different stages of PDAC, chemotherapy regimens, radiation, duration of treatment, and assessment of effect. This review aims to summarize the current progress and controversies of NAT in PDAC.

Abstract
OBJECTIVE Given the frequent adverse events with multidrug chemotherapy, not only the survival benefit but also the feasibility of using neoadjuvant chemotherapy to treat pancreatic cancer need to be clarified. SUMMARY OF BACKGROUND DATA Although the development of multidrug chemotherapy regimens has improved the survival outcomes of patients with unresectable pancreatic cancer, the benefits of these treatments in the neo-adjuvant setting remain controversial. METHODS Patients with borderline-resectable pancreatic cancer were enrolled and randomly assigned to receive neoadjuvant chemotherapy with either FOLFIRINOX or gemcitabine with nab-paclitaxel (GEM/nab-PTX). After the completion of chemotherapy, patients underwent surgical resection when feasible. This study (NUPAT-01) was a randomized phase II trial, and the primary endpoint was the R0 resection rate. RESULTS Fifty-one patients were enrolled in this study [FOLFIRINOX (n = 26) and GEM/nab-PTX (n = 25)]. A total of 84.3% (n = 43/51) of the patients eventually underwent surgery, and R0 resection was achieved in 67.4% (n = 33/ 51) of the patients. Adverse events (grade >3) due to neoadjuvant treatment were observed in 45.1% of the patients (n = 23/51), and major surgical complications occurred in 30.0% (n = 13/43), with no mortality noted. The intention-to-treat analysis showed that the 3-year overall survival rate was 54.7%, with a median survival time of 39.4 months, and a significant difference in overall survival was not observed between the FOLFIRINOX and GEM/nab-PTX groups. CONCLUSIONS These results indicate that neoadjuvant chemotherapy with FOLFIRINOX or GEM/nab-PTX is feasible and well tolerated, achieving an R0 resection rate of 67.4%. The survival of patients was even found to be favorable in the intention-to-treat analysis.

Abstract
OBJECTIVES Nab-paclitaxel has radiosensitizing antitumor efficacy in pancreatic cancer. We aimed to establish maximum tolerated dose (MTD) of nab-paclitaxel with radiotherapy in unresectable locally advanced pancreatic cancer. METHODS In a phase I dose escalation trial patients received weekly nab-paclitaxel for 6 weeks with external beam radiotherapy (EBRT). 3 + 3 design was used with nab-paclitaxel doses: 25 mg/m 2 (cohort 1), 50 mg/m 2 (cohort 2), 75 mg/m 2 (cohort 3), and 100 mg/m 2 (cohort 4). Primary endpoint was MTD. Secondary objectives were progression-free survival and overall survival. RESULTS Fourteen patients were recruited. Median age was 69 years (range, 40-86). Grade 1/2 toxicities were nausea (93%), vomiting (54%), diarrhea (57%), and fatigue (69%). There were no dose limiting toxicities (DLT) in cohorts 1 to 3. In cohort 4, DLTs of febrile neutropenia and enterocolitis were observed in patient 1. Subsequent DLT of febrile neutropenia and enterocolitis occurred in patient 5 in the expanded cohort. Following chemoradiotherapy median progression-free survival was 4.7 months (95% confidence interval, 2.5-27.5) and median overall survival was 10.8 months (95% confidence interval, 6.37-25.2). CONCLUSIONS Nab-paclitaxel and EBRT was well-tolerated at doses below 100 mg/m 2 . The MTD and recommended phase II study dose for nab-paclitaxel with EBRT is 75 mg/m 2 in this disease.

Abstract
The intracellular non-receptor tyrosine protein kinase Focal adhesion kinase (FAK) is a key signalling regulator, which mediates tumor survival, invasion, metastasis, and angiogenesis through its kinase catalytic functions and non-kinase scaffolding functions. Previous efforts have clarified that it is crucial to address both FAK kinase and scaffolding functions instead of just inhibiting FAK kinase activity because it may be insufficient to completely block FAK signaling. Proteolysis targeting chimera (PROTAC) technology is a method of targeting a specific protein and inducing its degradation in the cell, which can simultaneously eliminate both kinase-dependent enzymatic functions and scaffolding functions. In current study, we designed and synthesized a series of novel FAK PROTACs and the optimal PROTAC B5 exhibited potent FAK affinity with an IC50 value of 14.9 nM. Furthermore, in A549 cells, PROTAC B5 presented strong FAK degradation activity (86.4% degradation @ 10 nM), powerful antiproliferative activity (IC50 = 0.14 ± 0.01 μM) and inhibited cell migration and invasion in a concentration-dependent manner. Additionally, the in vitro preliminary drug-like properties evaluation of PROTAC B5 showed outstanding plasma stability and moderate membrane permeability. Together, current results provided a promising FAK PROTAC B5 as lead compound for cancer-related drug discovery and FAK-degradation functions exploration in biological systems.

Abstract
BACKGROUND In recent years, there have been changes in the treatment of ductal pancreatic carcinoma with regard to multimodal therapy and also surgical therapy. These changes have not yet been explored in large nationwide studies in Germany. The present work gives an initial overview from a surgical perspective of the developments in diagnosis, therapy and survival of pancreatic cancer within the last 19 years in Germany. METHODS In this cohort of 18 clinical cancer registries in Germany, patients with a diagnosis of ductal pancreatic cancer from 2000-2018 were included. The patients were categorised according to the years of diagnosis (2000-2009 vs. 2010-2018) and treatment modalities and compared. RESULTS In the cohort of approx. 48000 patients with ductal pancreatic cancer, the number of newly diagnosed cases increased from approx. 18000 to 30000 patients in the two ten-year periods. The median overall survival increased slightly but statistically significantly from 7.1 to 7.9 months (p < 0.001). The resection rate increased from 25% to 32%, with the proportion of patients for whom no specific therapy was reported decreased by 11%. The rate of palliative chemotherapy and neoadjuvant chemotherapy also increased from 16% to 20% of the patients and from less than 1% to 2% of the patients, respectively. The median survival in the curatively treated subgroups was up to 24 months. SUMMARY The cancer registry data appear to confirm the known increase in the incidence of pancreatic cancer in the western world. Resection rates and the rates of treatment with neoadjuvant and palliative intent also increased. The overall survival of all patients with ductal pancreatic cancer only increased marginally. In the subgroups of patients who were treated with curative intent, however, significantly longer survival times were found.

Abstract
Local, sustained drug delivery of potent therapeutics holds promise for the treatment of a myriad of localized diseases while eliminating systemic side effects. However, introduction of drug delivery depots such as viscous hydrogels or polymer-based implants is highly limited in stiff tissues such as desmoplastic tumors. Here, we present a method to create materials-free intratumoral drug depots through Tissue-Reactive Anchoring Pharmaceuticals (TRAPs). TRAPs diffuse into tissue and attach locally for sustained drug release. In TRAPs, potent drugs are modified with ECM-reactive groups and then locally injected to quickly react with accessible amines within the ECM, creating local drug depots. We demonstrate that locally injected TRAPs create dispersed, stable intratumoral depots deep within mouse and human pancreatic tumor tissues. TRAPs depots based on ECM-reactive paclitaxel (TRAP paclitaxel) had better solubility than free paclitaxel and enabled sustained in vitro and in vivo drug release. TRAP paclitaxel induced higher tumoral apoptosis and sustained better antitumor efficacy than the free drug. By providing continuous drug access to tumor cells, this material-free approach to sustained drug delivery of potent therapeutics has the potential in a wide variety of diseases where current injectable depots fall short.

Identifying optimal candidates for tumor resection among borderline and locally advanced pancreatic cancer: A population-based predictive model. Pancreatology 2022; 22:286-293. [PMID: 35058130 DOI: 10.1016/j.pan.2022.01.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Revised: 01/03/2022] [Accepted: 01/07/2022] [Indexed: 12/11/2022]
Abstract
BACKGROUND Whether patients with borderline resectable and locally advanced pancreatic cancer (BR/LAPC) benefit from resection of the primary cancer is controversial. We developed a nomogram to screen who would benefit from surgery for the primary tumor. METHODS We identified patients from the Surveillance, Epidemiology, and End Results (SEER) database and then divided them into surgical and non-surgical groups. A 1:1 propensity score matching (PSM) was used to mitigate the bias. We hypothesized that patients who underwent surgery would benefit from surgery by having a longer median overall survival (OS) than patients who did not undergo surgery. Univariate and multivariate logistic regression analyses were used to determine the variables affecting surgical outcomes, and a nomogram was created based on the multivariate logistic results. Finally, we verified the discrimination and calibration of the nomogram with receiver operator characteristic (ROC) curve and calibration plots. RESULTS A total of 518 pairs of surgical and non-surgical pancreatic cancer patients were matched after PSM. Survival curves showed longer OS in the surgical group than in the non-surgical group, median survival times were 14 months versus 8 months. In the surgical group, 340 (65.63%) patients have a longer survival time than 8 months (beneficial group). Multifactorial logit regression results showed that including age, tumor size, degree of differentiation, and chemotherapy were significant influences on the benefit of surgery for primary tumors and were used as predictors to construct a nomogram. The area under the ROC curve (AUC) reached 0.747 and 0.706 in the training and validation sets. CONCLUSION We developed a practical predictive model to support clinical decision-making that can be used to help clinicians determine if there is a benefit to surgical resection of the primary tumor in patients with BR/LAPC.

Abstract
Background and study aims In patients with pancreatic cancer (PC), patient-derived organoid cultures can be useful tools for personalized drug selection and preclinical evaluation of novel therapies. To establish a less invasive method of creating organoids from a patient's tumor, we examined whether PC organoids can be established using residual samples from saline flushes (RSSFs) during endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). Methods Five patients with PC who underwent EUS-FNA were enrolled in a prospective study conducted at our institution. RSSFs obtained during EUS-FNA procedures were collected. An organoid culture was considered as established when ≥ 5 passages were successful. Organoid-derived xenografts were created using established organoids. Results EUS-FNA was performed using a 22- or 25-gauge lancet needle without complications. Patient-derived organoids were successfully established in four patients (80.0 %) with the complete medium and medium for the selection of KRAS mutants. Organoid-derived xenografts were successfully created and histologically similar to EUS-FNA samples. Conclusions Patient-derived PC organoids were successfully established using EUS-FNA RSSFs, which are produced as a byproduct of standard manipulations, but are usually not used for diagnosis. This method can be applied to all patients with PC, without additional invasive procedures, and can contribute to the development of personalized medicine and molecular research.

Predictive factors of operability after neoadjuvant chemotherapy in resectable or borderline resectable pancreatic cancer: a single-center retrospective study. Discov Oncol 2022; 13:2. [PMID: 35201490 PMCID: PMC8777497 DOI: 10.1007/s12672-021-00462-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Accepted: 12/22/2021] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND/AIMS Recently neoadjuvant chemotherapy (NAC) for pancreatic cancer has been shown to be superior to upfront surgery, but it remains a matter of debate for resectable cases. In clinical practice, some resectable cases may become unresectable after NAC. This study aimed to reveal the outcomes after NAC and to clarify the characteristics of unresected cases. METHODS The medical records of 142 patients who underwent NAC between 2016 and 2020 were retrospectively reviewed. Patient characteristics, effectiveness of NAC, and outcomes were compared between the surgical group and non-surgical group (NSG). Furthermore, the risk of recurrence limited to in the patients who received NAC with gemcitabine plus nab-paclitaxel, which were mostly administered in this cohort, following R0/R1 resection was assessed. RESULTS The overall and R0 resection rates after NAC were 89.1% and 79.7%, respectively. The neutrophil to lymphocyte ratio (NLR) > 2.78 (p = 0.0120) and anatomical borderline resectable pancreatic cancer (p = 0.0044) revealed a statistically significantly correlation with the NSG. On the other hand, NAC week < 8 (p = 0.0285), radiological response, stable disease or progression disease (p = 0.0212), and pathological stage > IIA (P = 0.0003) were significantly associated with recurrence. The tumor response rate was approximately 26.1%, and three patients with ≥ 30% reduction of primary tumor lost excision opportunities because of metastasis, interstitial pneumonia, and vascular invasion. CONCLUSIONS This study shows incomplete tumor shrinkage benefits, but pre-NAC NLR is a predictive factor for predicting operability after NAC. The NLR can be easily calculated by normal blood test, and can be considered as a suitable marker of operability.

Surgery After Conversion Therapy With PD-1 Inhibitors Plus Tyrosine Kinase Inhibitors Are Effective and Safe for Advanced Hepatocellular Carcinoma: A Pilot Study of Ten Patients. Front Oncol 2021; 11:747950. [PMID: 34737958 PMCID: PMC8560793 DOI: 10.3389/fonc.2021.747950] [Citation(s) in RCA: 36] [Impact Index Per Article: 12.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Accepted: 09/20/2021] [Indexed: 12/12/2022] Open
Abstract
Background and Aims Immunotherapy with PD-1 inhibitors combined with tyrosine kinase inhibitors (TKIs) has been proven to be effective against advanced hepatocellular carcinoma (HCC). The aim of this study was to identify the feasibility and safety of subsequent salvage surgery after this combination therapy. Methods and Patients A retrospective analysis was performed on patients with primary HCC with major vascular invasion between 2018 and 2019. All cases were treated with a combination of a PD-1 inhibitor and TKI agents and subsequent surgery. Results A total of 10 HCC cases with major vascular invasion met the successful conversion criteria after the combination therapy, and eight patients underwent subsequent salvage surgery after both radiology and 3D quantitative oncological assessment. Partial response (PR) was recorded in 7 of 10 patients and complete response (CR) in 3 of 10 patients before salvage surgery. Salvage surgery included right hepatectomy, left hepatectomy, and anatomic segmental hepatectomy. The mean intraoperative blood loss was 1,650 ml (50–3,000 ml). No complications beyond Clavien–Dindo level III or postoperative mortality were observed. The viable tumor cell rate of the PR cases (modified response evaluation criteria in solid tumors, mRECIST) varied from 1.5% to 100%, and only one patient had pathology-proven pathological complete response (pCR). The postoperative median follow-up time was 19.7 months (9.1–24.9 months). The 12-month recurrence-free survival rate of all cases who underwent salvage surgery was 75%. Conclusion Salvage surgery was effective and safe after conversion therapy with PD-1 inhibitors plus TKIs and may increase the long-term oncological benefit for patients with unresectable HCC.

Abstract
The prevalence of pancreatic cancer is sharply increasing recently, which significantly increases the economic burden of the population. At present, the primary treatment of resectable pancreatic cancer is surgical resection, followed by chemotherapy with or without radiation. However, the recurrence rates remain high even after R0 resection. This treatment strategy does not distinguish undetected metastatic disease, and it is prone to postoperative complications. Neoadjuvant therapies, including neoadjuvant chemotherapy and radiotherapy, is being increasingly utilized in borderline resectable as well as resectable pancreatic cancer. This review summarized and discussed clinical trials of neoadjuvant therapy for pancreatic cancer, comparing resection rates, outcome measures, and adverse reactions between neoadjuvant chemotherapy and neoadjuvant chemoradiotherapy.

The effect of preoperative chemotherapy and chemoradiotherapy on pancreatic fistula and other surgical complications after pancreatic resection: a systematic review and meta-analysis of comparative studies. HPB (Oxford) 2021; 23:1321-1331.

Abstract
BACKGROUND Preoperative chemo- or chemoradiotherapy is recommended for borderline-resectable pancreatic cancer. The aim of this study was to determine the impact of preoperative therapy on surgical complications in patients with resected pancreatic cancer. METHODS This systematic review and meta-analysis included studies reporting on the rate of surgical complications after preoperative chemo- or chemoradiotherapy versus immediate surgery in pancreatic cancer patients. The primary endpoint was the rate of grade B/C POPF. Pooled odds ratios were calculated using random-effects models. RESULTS Forty-one comparative studies including 25,389 patients were included. Vascular resections were more often performed after preoperative therapy (29.4% vs. 15.7%, p < 0.001). Preoperative therapy was associated with a lower rate of grade B/C POPF as compared to immediate surgery (pooled OR 0.47, 95%CI 0.38-0.58). This reduction was mostly obtained by preoperative chemoradiotherapy (OR 0.46, 95%CI 0.29-0.73), but not by preoperative chemotherapy alone (OR 0.83, 95%CI 0.59-1.16). No difference was demonstrated for major morbidity, mortality, postpancreatectomy haemorrhage, delayed gastric emptying and overall morbidity. CONCLUSION Preoperative chemo- and chemoradiotherapy in patients with pancreatic cancer appears to be safe with respect to POPF and other surgical complications as compared to immediate surgery. The reduced rate of POPF appears to be attributable to preoperative chemoradiation.

Cancers (Basel) 2021; 13:cancers13174326.

Abstract
Simple Summary Due to the availability of effective combination chemotherapies such as gemcitabine/nab-paclitaxel (GNP) or FOLFIRINOX, neoadjuvant treatment of borderline resectable (BRPC) and locally advanced pancreatic cancer (LAPC) has been increasingly investigated in recent years. However, due to toxicity, FOLFIRINOX is only available for selected patients and data on GNP are scarce. The aim of this systematic review and meta-analysis, which is to our knowledge the first addressing this question, is to evaluate the value of GNP in patients with BRPC and LAPC. We provide a comprehensive overview on data of 21 studies, comprising 950 patients treated with neoadjuvant GNP. The pooled overall and R0 resection rates were 36% and 26%, respectively. Resection rates were higher in BRPC (49%) compared to LAPC (16%). With acceptable toxicity and a median overall survival rate ranging from 12 to 30 months, neoadjuvant GNP has considerable value in this setting, with more prospective trials being warranted. Abstract Therapy with gemcitabine and nab-paclitaxel (GNP) is the most commonly used palliative chemotherapy, but its advantage in the neoadjuvant setting remains unclear. Accordingly, our aim is to evaluate the impact of first-line neoadjuvant therapy with GNP in patients with borderline resectable (BRPC) and locally advanced pancreatic cancer (LAPC). A systematic search for published studies until August 2020 was performed. The primary endpoint included resection and R0 resection rates in the intention-to-treat population. Secondary endpoints were response rate, survival and toxicity. Among 21 studies, 950 patients who received neoadjuvant GNP were evaluated. Treatment with GNP resulted in surgical resection and R0 resection rates as follows: 49% (95% CI 30–68%) and 36% (95% CI 17–58%) for BRPC and 16% (95% CI 7–26%) and 11% (95% CI 5–19%) for LAPC, respectively. The objective response rates and the median overall survival (mOS) ranged from 0 to 67% and 12 to 30 months, respectively. Neutropenia (range 5–77%) and neuropathy (range 0–22%) were the most commonly reported grade 3 to 4 adverse events. Neoadjuvant chemotherapy with GNP can be performed safely and with valuable effects in patients with BRPC and LAPC. The utility of GNP in comparison to FOLFIRINOX in the neoadjuvant setting requires further investigation in prospective randomized trials.

Abstract
BACKGROUND Neoadjuvant therapy is used for borderline resectable pancreatic ductal adenocarcinoma (PDAC) with high risk of incomplete resection and early recurrence. Because distal PDAC is rare, the optimal criteria for neoadjuvant therapy specific for distal PDAC remain unclear. We hypothesized large distal PDAC would recur earlier than small distal PDAC. OBJECTIVE The aim of this study was to identify the risk factors for failure of upfront resection for resectable distal PDAC. METHODS The study cohort comprised 158 patients with resectable distal PDAC who underwent radical resection. The long-term outcomes were recurrence-free survival (RFS), disease-specific survival (DSS), and post-recurrence survival (PRS). RESULTS R0 resection was achieved in 92% of patients, and median DSS for the entire cohort was 31 months. Among 103 patients who developed recurrence, 32 (31%) developed recurrence within 6 months. The median PRS and DSS for those with early recurrence was 6 and 10 months, respectively, compared with 11 and 30 months, respectively, for those with late recurrence (p = 0.017 and p < 0.001, respectively). Patients with tumors > 4 cm had higher rates of R1 resection (16%) and concomitant resection of another organ (19%) than those with smaller tumors (4% and 2%, p = 0.009 and p < 0.001, respectively). In multivariate analysis, tumor > 4 cm remained a significant predictor of early recurrence (p < 0.001, hazard ratio [HR] 6.51), shorter RFS (p = 0.018, HR 1.71), and shorter DSS (p = 0.002, HR 2.07). CONCLUSION Tumor size > 4 cm is a reliable predictor of early recurrence after resection of distal PDAC, and neoadjuvant therapy may help select patients who can benefit from radical resection.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) has a dismal prognosis, with a median survival time of 10-12 months. Clinically, these poor outcomes are attributed to several factors, including late stage at the time of diagnosis impeding resectability, as well as multi-drug resistance. Despite the high prevalence of drug-resistant phenotypes, nearly all patients are offered chemotherapy leading to modest improvements in postoperative survival. However, chemotherapy is all too often associated with toxicity, and many patients elect for palliative care. In cases of inoperable disease, cytotoxic therapies are less efficacious but still carry the same risk of serious adverse effects, and clinical outcomes remain particularly poor. Here we discuss the current state of pancreatic cancer therapy, both surgical and medical, and emerging factors limiting the efficacy of both. Combined, this review highlights an unmet clinical need to improve our understanding of the mechanisms underlying the poor therapeutic responses seen in patients with PDAC, in hopes of increasing drug efficacy, extending patient survival, and improving quality of life.

Synthesis of a gemcitabine-modified phospholipid and its subsequent incorporation into a single microbubble formulation loaded with paclitaxel for the treatment of pancreatic cancer using ultrasound-targeted microbubble destruction. Eur J Pharm Biopharm 2021; 165:374-382. [PMID: 34038797 DOI: 10.1016/j.ejpb.2021.05.018] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 05/05/2021] [Accepted: 05/18/2021] [Indexed: 12/24/2022]
Abstract
Gemcitabine and nab-paclitaxel (Abraxane®) is a standard of care chemotherapy combination used in the treatment of patients with advanced pancreatic cancer. While the combination has shown a survival benefit when compared to gemcitabine monotherapy, it is associated with significant off-target toxicity. Ultrasound targeted microbubble destruction (UTMD) has emerged as an effective strategy for the site-specific deposition of drug-payloads. However, loading a single microbubble formulation with two drug payloads can be challenging and often involves several manipulations post-microbubble preparation that can be cumbersome and generally results in low / inconsistent drug loadings. In this manuscript, we report the one-pot synthesis of a gemcitabine functionalised phospholipid and use it to successfully generate stable microbubble formulations loaded with gemcitabine (Lipid-Gem MB) or a combination of gemcitabine and paclitaxel (Lipid-Gem-PTX MB). Efficacy of the Lipid-Gem MB and Lipid-Gem-PTX MB formulations, following ultrasound (US) stimulation, was evaluated in a three-dimensional (3D) PANC-1 spheroid model of pancreatic cancer and a mouse model bearing ectopic BxPC-3 tumours. The results demonstrated a significant reduction in the cell viability in spheroids for both formulations reducing from 90 ± 10% to 62 ± 5% for Lipid-Gem MB and 84 ± 10% to 30 ± 6% Lipid-Gem-PTX MB following US irradiation. When compared with a clinically relevant dose of free gemcitabine and paclitaxel (i.e. non-particle bound) in a BxPC-3 murine pancreatic tumour model, both formulations also improved tumour growth delay with tumours 40 ± 20% and 40 ± 30% smaller than the respective free drug formulation when treated with Lipid-Gem MB and Lipid-Gem-PTX MB respectively, at the conclusion of the experiment. These results highlight the potential of UTMD mediated Gem / PTX as a treatment for pancreatic cancer and the facile preparation of Lipid-Gem-PTX MBs using a gemcitabine functionalised lipid should expedite clinical translation of this technology.

Abstract
Introduction Although neoadjuvant treatment is recommended for patients with borderline resectable pancreatic cancer (BRPC), no standard neoadjuvant regimen has been established for BRPC with arterial involvement (BRPC-A), which is associated with a higher risk of margin-positive resection and poorer prognosis than BRPC with only venous involvement. Gemcitabine plus nab-paclitaxel (GnP) has been reported to significantly reduce tumor size in metastatic pancreatic cancer, and some retrospective studies suggested that neoadjuvant GnP for BRPC improved resectability and survival. Methods and analysis A prospective multicenter single-arm phase II study is conducted to evaluate the safety and efficacy of GnP as neoadjuvant chemotherapy for BRPC-A. The primary endpoint is the R0 resection rate. The secondary endpoints are the neoadjuvant chemotherapy response rate, resection rate, pathological response rate, incidence rate of adverse events, and quality of life. Ethics and dissemination This study protocol was approved by the institutional review board of Kyushu University (no. 181). The results will be published in a peer-reviewed journal and will be presented at medical meetings. Highlights Strategy for borderline resectable pancreatic cancer involving arteries (BRPC-A).There is no standard regimen for neoadjuvant chemotherapy for BRPC-A.Gemcitabine plus nab-paclitaxel (GnP) shows significant tumor shrinkage.Neoadjuvant GnP for BRPC-A increases resectability and margin-negative resection.

Abstract
Background Even after curative resection, pancreatic ductal adenocarcinoma (PDAC) patients suffer a high rate of recurrence. There is an unmet need to predict which patients will experience early recurrence after resection in order to adjust treatment strategies. Methods Data of patients with resectable PDAC undergoing surgical resection between January 2005 and September 2018 were reviewed to stratify for early recurrence defined as occurring within 6 months of resection. Preoperative data including demographics, tumor markers, blood immune-inflammatory factors and clinicopathological data were examined. We employed Elastic Net, a sparse modeling method, to construct models predicting early recurrence using these multiple preoperative factors. As a result, seven preoperative factors were selected: age, duke pancreatic monoclonal antigen type 2 value, neutrophil:lymphocyte ratio, systemic immune-inflammation index, tumor size, lymph node metastasis and is peripancreatic invasion. Repeated 10-fold cross-validations were performed, and area under the receiver operating characteristic curve (AUC) and decision curve analysis were used to evaluate the usefulness of the models. Results A total of 136 patients was included in the final analysis, of which 35 (34%) experienced early recurrence. Using Elastic Net, we found that 7 of 14 preoperative factors were useful for the predictive model. The mean AUC of all models constructed in the repeated validation was superior to the standard marker CA 19–9 (0.718 vs 0.657), whereas the AUC of the model constructed from the entire patient cohort was 0.767. Decision curve analysis showed that the models had a higher mean net benefit across the majority of the range of reasonable threshold probabilities. Conclusion A model using multiple preoperative factors can improve prediction of early resectable PDAC recurrence.

Abstract
Imaging studies play an important role in the detection, diagnosis, assessment of resectability, staging, and determination of patient-tailored treatment options for pancreatic adenocarcinoma. Recently, for patients diagnosed with borderline resectable or locally advanced pancreatic cancers, it is recommended to consider curative-intent surgery following neoadjuvant or palliative therapy, if possible. This review covers how to interpret imaging tests and what to consider when assessing resectability, diagnosing distant metastasis, and re-assessing the resectability of pancreatic cancer after neoadjuvant or palliative therapy.

Abstract
Neoadjuvant chemotherapy (NAC) has become a standard treatment for borderline resectable pancreatic ductal adenocarcinoma (PDAC). The present study examined the maximum tolerated dose of NAC with gemcitabine plus nab-paclitaxel (GnP) in patients with resectable PDAC. Between 2015 and 2019, 39 patients with resectable PDAC were enrolled in the present study. GnP was administered for two 28-day cycles on days 1, 8 and 15. The planned doses for levels 1, 2 and 3 were 75, 100 and 125 mg/m2, respectively, for nab-paclitaxel and 600, 800 and 1,000 mg/m2, respectively, for gemcitabine. Dose-limiting toxicity (neutropenia, anemia, thrombocytopenia and/or liver injury) was observed in 44.4% of patients treated at dose level 1 (21 patients) and 60.0% of those treated at dose level 2 (18 patients). Therefore, the maximum tolerated dose was set as level 1. Six patients withdrew from protocol treatment because of non-hematologic adverse events (skin rash, pancreatitis and biliary tract infection). Among the 31 patients with pathologically confirmed PDAC, partial response, stable disease and disease progression were recorded in 4 (12.9%), 24 (77.4%) and 3 (9.7%) patients, respectively. NAC significantly reduced tumor size according to computed tomography, and CA19-9 levels and the 18F-fluorodeoxyglucose maximum standardized uptake value were decreased in positron emission tomography. No postoperative complications attributable to NAC were recognized. Among the 27 patients with PDAC who underwent resection, the pathological treatment effect was judged as grades Ia, Ib and II in 21 (77.8%), 4 (14.8%) and 2 (7.4%) patients, respectively. R0 resection was performed in 24 out of 27 patients (88.9%). Adjuvant chemotherapy with oral S-1 was administered to 21 out of 27 patients (77.8%). In conclusion, NAC with GnP was safe and feasible for resectable PDAC at dose level 1. In the future, verification of the long-term results of the present study will be necessary, and a phase II clinical trial is anticipated.

Abstract
Simple Summary For borderline pancreatic cancer, upfront surgery was standard in the past, and the usefulness of neoadjuvant treatment has been reported in recent years. However, few studies have been conducted to date on whether there is a difference in optimal treatment between borderline resectable pancreatic cancer invading the portal vein (BR-PV) or abutting major arteries (BR-A). The objective of this study was to investigate the optimal neoadjuvant therapy for BR-PV or BR-A. We retrospectively analyzed 88 patients with BR-PV and 111 patients with BR-A. In this study, we found that neoadjuvant treatment using new chemotherapy (FOLFIRINOX or gemcitabine along with nab-paclitaxel) is essential for improving the prognosis of BR pancreatic cancer. These findings suggest that prognosis may be prolonged by maintaining good nutritional status during preoperative treatment. Abstract Background: The objective of this study was to investigate the optimal neoadjuvant therapy (NAT) for borderline resectable pancreatic cancer invading the portal vein (BR-PV) or abutting major arteries (BR-A). Methods: We retrospectively analyzed 88 patients with BR-PV and 111 patients with BR-A. Results: In BR-PV patients who underwent upfront surgery (n = 46)/NAT (n = 42), survival was significantly better in the NAT group (3-year overall survival (OS): 5.8%/35.5%, p = 0.004). In BR-A patients who underwent upfront surgery (n = 48)/NAT (n = 63), survival was also significantly better in the NAT group (3-year OS:15.5%/41.7%, p < 0.001). The prognosis tended to be better in patients who received newer chemotherapeutic regimens, such as FOLFIRINOX and gemcitabine with nab-paclitaxel. In 36 BR-PV patients who underwent surgery after NAT, univariate analysis revealed that normalization of tumor marker (TM) levels (p = 0.028) and preoperative high prognostic nutritional index (PNI) (p = 0.022) were significantly associated with a favorable prognosis. In 39 BR-A patients who underwent surgery after NAT, multivariate analysis revealed that preoperative PNI > 42.5 was an independent prognostic factor (HR: 0.15, p = 0.014). Conclusions: NAT using newer chemotherapy is essential for improving the prognosis of BR pancreatic cancer. These findings suggest that prognosis may be prolonged by maintaining good nutritional status during preoperative treatment.

Abstract
Simple Summary The development of new polychemotherapy regimens in patients with metastatic pancreatic cancer (mPDAC) have demonstrated significant improvement in clinical outcome, but evidence of the role of surgery following a favorable response to initial chemotherapy (IC) is still poor. The aim of the study is to analyze the impact of surgery following IC on survival in mPDAC, focusing on oligometastatic disease to the liver. Data retrieved from available literature confirm increased survival in selected oligometastatic patients treated with surgery + IC compared to IC alone (23–56 months vs. 11–16.4 months), suggesting a potential role for conversion surgery in a tailored and multimodality approach to pancreatic cancer patients. Better knowledge of tumor biology and a wide consensus on diagnostic criteria could lead to the consideration of oligometastatic disease as a particular and different stage of disease. Abstract Background: the improved survival rates achieved using new polychemotherapy regimens in patients with metastatic pancreatic cancer (mPDAC) have suggested a potential role for surgery following a favorable response to initial chemotherapy (IC). The purpose of this systematic review is to summarize the available evidence on the role of surgery following IC in mPDAC, focusing on oligometastatic disease to the liver (lmPDAC). Methods: studies reporting on patients with lmPDAC undergoing surgery after IC were included. The main outcome was overall survival (OS). Results: six observational retrospective studies were included in the qualitative analysis. Data were retrieved on 2087 patients. The most common IC regimen in patients undergoing surgery was FOLFIRINOX (N 84, 73%). Only three studies reported survival comparison among patients treated with IC+surgery vs. IC alone. Median OS varied from 23 to 56 months after conversion surgery vs. 11 to 16.4 months after IC alone. Conclusions: despite wide heterogeneity of chemotherapy regimens, different downstaging criteria and potential selection biases, patients with oligometastatic lmPDAC undergoing surgery after IC have significantly higher survival rates compared to patients treated with IC alone. Future trials are needed for definition of univocal criteria of downstaging, oligometastatic definition and indications for surgery.

Abstract
Merkel cell carcinoma (MCC) is a rare aggressive form of skin cancer originating in neuroendocrine cells. The antiprogrammed death ligand 1 (PD-L1) monoclonal antibody (mAb) avelumab has been approved for treatment of MCC, but options are limited, should it be ineffective as a monotherapy. Combined therapy with low/moderate dose nab-paclitaxel and an interleukin 15 (IL-15)-based therapeutic such as the IL-15 ‘superagonist’ N-803 may increase response by activation of the immune system. The case of a 71-year-old man diagnosed with MCC who achieved and maintained a complete response (CR) by treatment with the anti-PD-L1 mAb avelumab in combination with IL-15 superagonist N-803 and nab-paclitaxel (Abraxane) is presented. Avelumab treatment alone resulted in a response in a para-aortic lesion, but not the other tumor masses. N-803 was added, followed by nab-paclitaxel; CT showed a decrease in the size of the abdominal mass at 1 month, near resolution at 3 months and CR at 5 months. Abraxane was discontinued after the first CR on CT, and the patient continues on avelumab/N-803 treatment and maintains a CR. Combination of avelumab with low/moderate-dose chemotherapy and an immune enhancer such as N-803 may offer a viable treatment option for MCC patients for whom avelumab therapy alone was not effective.

Abstract
BACKGROUND Iron is required for cellular metabolism, and rapidly proliferating cancer cells require more of this essential nutrient. Therefore, iron regulation may well represent a new avenue for cancer therapy. We have reported, through in vitro and in vivo research involving pancreatic cancer cell lines, that the internal-use, next-generation iron chelator deferasirox (DFX) exhibits concentration-dependent tumour-suppressive effects, among other effects. After performing a microarray analysis on the tumour grafts used in that research, we found that DFX may be able to suppress the cellular movement pathways of pancreatic cancer cells. In this study, we conducted in vitro analyses to evaluate the effects of DFX on the invasive and migratory abilities of pancreatic cancer cells. METHODS We used pancreatic cancer cell lines (BxPC-3, Panc-1, and HPAF II) to examine the efficacy of DFX in preventing invasion in vitro, evaluated using scratch assays and Boyden chamber assays. In an effort to understand the mechanism of action whereby DFX suppresses tumour invasion and migration, we performed G-LISA to examine the activation of Cdc42 and Rac1 which are known for their involvement in cellular movement pathways. RESULTS In our scratch assays, we observed that DFX-treated cells had significantly reduced invasive ability compared with that of control cells. Similarly, in our Boyden chamber assays, we observed that DFX-treated cells had significantly reduced migratory ability. After analysis of the Rho family of proteins, we observed a significant reduction in the activation of Cdc42 and Rac1 in DFX-treated cells. CONCLUSIONS DFX can suppress the motility of cancer cells by reducing Cdc42 and Rac1 activation. Pancreatic cancers often have metastatic lesions, which means that use of DFX will suppress not only tumour proliferation but also tumour invasion, and we expect that this will lead to improved prognoses.

Adjuvant nab-paclitaxel plus gemcitabine vs gemcitabine alone for resected pancreatic ductal adenocarcinoma: A single center experience in China. World J Clin Cases 2020; 8:2778-2786. [PMID: 32742988 PMCID: PMC7360710 DOI: 10.12998/wjcc.v8.i13.2778] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/17/2020] [Revised: 05/02/2020] [Accepted: 06/07/2020] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Nab-paclitaxel plus gemcitabine (AG) has resulted in higher tumor response and survival rates for metastatic or advanced pancreatic ductal adenocarcinoma (PDAC) compared with gemcitabine (GEM) alone.
AIM To examine the feasibility and safety of AG adjuvant chemotherapy of resectable PDAC.
METHODS We retrospectively analyzed patients with resected PDAC who received AG or GEM as postoperative adjuvant treatment between January 2013 and December 2016 at the Chinese People’s Liberation Army General Hospital, Beijing, China. The patients adopted combined nab-paclitaxel (125 mg/m2) and GEM (1 g/m2) or GEM (1 g/m2) alone treatment, on days 1 and 8 every 3 wk for six cycles, unless intolerable adverse events or disease progression occurred. The disease-free survival, overall survival (OS) and adverse events of the two groups were statistically analyzed.
RESULTS Compared with GEM, median disease-free survival (12.2 mo vs 15.8 mo, P = 0.039) and OS (20.6 mo vs 28.3 mo, P = 0.028) were significantly improved in the AG group. The 2-year OS rates were 63.3% and 43.3% in the AG and GEM groups, respectively. However, the incidence of sensory neuropathy was increased significantly in the AG than the GEM group (53.3% vs 23.3%, P < 0.001).
CONCLUSION In our initial experience, AG significantly improved disease-free survival and OS of patients with resected PDAC. AG may be a potential option for postoperative adjuvant chemotherapy of resectable PDAC.

Clinical implications of the serum CA19-9 level in "biological borderline resectability" and "biological downstaging" in the setting of preoperative chemoradiation therapy for pancreatic cancer. Pancreatology 2020; 20:919-928. [PMID: 32563596 DOI: 10.1016/j.pan.2020.05.020] [Citation(s) in RCA: 22] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Revised: 05/18/2020] [Accepted: 05/27/2020] [Indexed: 12/11/2022]
Abstract
BACKGROUND Biological factors are emphasized in borderline resectable pancreatic cancer (BRPC), and CA19-9 is an important factor for biological borderline resectability (b-BR). The aim of this study was to investigate the cut-off value of CA19-9 for biological borderline resectability and "biological downstaging" in chemoradiation therapy (CRT) for pancreatic cancer (PC). METHODS A total of 407 patients with anatomically resectable PC (a-R) and BRPC (a-BR) received preoperative gemcitabine-based CRT. The b-BR was determined, according to the CA19-9 value prior to preoperative CRT (pre-CA19-9), as the subgroup of a-R cases in which the survival was comparable with that in a-BR cases. "Biological downstaging" was determined based on prognostic analyses regarding the CA19-9 value after preoperative CRT (post-CA19-9) in association with the survival of R cases (a-R cases without the b-BR factor). RESULTS The 5-year survival of a-R patients with pre-CA19-9 > 120 U/mL was comparable with that of a-BR patients (44% vs 34%, p = 0.082). The survival of b-BR patients with post-CRT CA19-9 ≤ 37 U/mL (normalized) was comparably favorable with that of R patients (56% vs 65%, p = 0.369). The incidence of distant recurrence was higher in b-BR patients without post-CA19-9 normalization than in those with post-CA19-9 normalization (70% vs 50%, p = 0.003), while the incidence of local recurrence was comparable between these two groups (12% vs 13%, p = 0.986). CONCLUSIONS Biological BRPC was determined to be an anatomically resectable disease with pre-CA19-9 > 120 U/mL, and post-CA19-9 normalization indicated "biological downstaging" in b-BR in the preoperative CRT strategy.
