Sternby H, Andersson B. Nationwide trends and outcomes of neoadjuvant chemotherapy in pancreatic cancer - an analysis of the Swedish national pancreatic cancer registry. Scand J Gastroenterol 2022; 57:1361-1366.

Abstract
OBJECTIVES During the last decade, neoadjuvant therapy (NAT) for pancreatic cancer has become more frequent. Pathological response and overall survival are promising; however, various post-operative complications have been reported. Our primary aim was to compare the complication scenario of patients receiving NAT in borderline resectable and locally advanced disease with those who had upfront pancreatic surgery (UFS) for primarily resectable cancer. METHODS From the Swedish National Pancreatic and Periampullary Cancer Registry, patients resected for pancreatic ductal adenocarcinoma (PDAC) between 2010 and 2018 were identified. Data on patient characteristics, neoadjuvant therapy, post-operative complications and survival were obtained. Comparisons between groups as well as survival analysis were performed. RESULTS Within the total cohort of 13,948 patients, 1894 (median age 69 years, 51% men) were resected for PDAC. Among these, 112 (5.9%) patients received NAT followed by surgery. The patients who received NAT were younger (67 vs 70 years, p < .001), had a lower level of CA19-9 (47 vs 108, p = .001) and had to a larger extent vascular resection (58.9 vs 26.9%, p < .001) and total pancreatectomy performed (23.2 vs 9.1%, p < .001). No difference was found for major post-operative complications and there was no significant change in survival rate between the NAT and UFS groups (median 28 vs 26 months, p = .122). CONCLUSIONS When analyzing data from a national registry, no difference in post-operative complications was found between resected patients receiving UFS and NAT for PDAC. Also, the survival was equal between groups. NAT is a feasible treatment option for patients with potentially curable pancreatic cancer.

Abstract
ABSTRACT Despite recent advances, pancreatic ductal adenocarcinoma (PDAC) continues to be associated with dismal outcomes, with a cure evading most patients. While historic treatment for PDAC has been surgical resection followed by 6 months of adjuvant therapy, there has been a recent shift toward neoadjuvant treatment (NAT). Several considerations support this approach, including the characteristic early systemic spread of PDAC, and the morbidity often surrounding pancreatic resection, which can delay recovery and preclude patients from starting adjuvant treatment. The addition of NAT has been suggested to improve margin-negative resection rates, decrease lymph node positivity, and potentially translate to improved survival. Conversely, complications and disease progression can occur during preoperative treatment, potentially eliminating the chance of curative resection. As NAT utilization has increased, treatment durations have been found to vary widely between institutions with an optimal duration remaining undefined. In this review, we assess the existing literature on NAT for PDAC, reviewing treatment durations reported across retrospective case series and prospective clinical trials to establish currently used approaches and seek the optimal duration. We also analyze markers of treatment response and review the potential for personalized approaches that may help clarify this important treatment question and move NAT toward a more standardized approach.

EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2022; 48:707-717. [PMID: 34887165 PMCID: PMC8995357 DOI: 10.1016/j.ejso.2021.11.136] [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: 08/11/2021] [Revised: 10/25/2021] [Accepted: 11/29/2021] [Indexed: 11/27/2022]
Abstract
BACKGROUND Chyle leak (CL) is a clinically relevant complication after pancreatectomy. Its incidence and the associated risk factors are ill defined, and various treatments options have been described. There is no consensus, however, regarding optimal management. The present study aims to systematically review the literature on CL after pancreatectomy. METHODS A systematic review from PubMed, Scopus and Embase database was performed. Studies using a clear definition for CL and published from January 2000 to January 2021 were included. The PRISMA guidelines were followed during all stages of this systematic review. The MINORS score was used to assess methodological quality. RESULTS Literature search found 361 reports, 99 of which were duplicates. The titles and abstracts of 262 articles were finally screened. The references from the remaining 181 articles were manually assessed. After the exclusions, 43 articles were thoroughly assessed. A total of 23 articles were ultimately included for this review. The number of patients varied from 54 to 3532. Incidence of post pancreatectomy CL varied from 1.3% to 22.1%. Main risk factors were the extent of the surgery and early oral or enteral feeding. CL dried up spontaneously or after conservative management within 14 days in 53% to 100% of the cases. CONCLUSIONS The extent of surgery is the most common predictor of risk of CL. Conservative treatment has been shown to be effective in most cases and can be considered the treatment of choice. We propose a management algorithm based on the current available evidence.

Abstract
Pancreatic cancer is the fourth leading cause of cancer-related death and the second gastrointestinal cancer-related death in the United States. Early detection and accurate diagnosis and staging of pancreatic cancer are paramount in guiding treatment plans, as surgical resection can provide the only potential cure for this disease. The overall prognosis of pancreatic cancer is poor even in patients with resectable disease. The 5-year survival after surgical resection is ~10% in node-positive disease compared to ~30% in node-negative disease. The advancement of imaging studies and the multidisciplinary approach involving radiologists, gastroenterologists, advanced endoscopists, medical, radiation, and surgical oncologists have a major impact on the management of pancreatic cancer. Endoscopic ultrasonography is essential in the diagnosis by obtaining tissue (FNA or FNB) and in the loco-regional staging of the disease. The advancement in EUS techniques has made this modality a critical adjunct in the management process of pancreatic cancer. In this review article, we provide an overall description of the role of endoscopic ultrasonography in the diagnosis and staging of pancreatic cancer.

Abstract
OBJECTIVES Indications of preoperative treatment for resectable (R-) or borderline resectable (BR-) pancreatic ductal adenocarcinoma (PDAC) are unclear, and the protocol remains to be standardized. METHODS Included 65 patients with R- and BR-PDAC with venous involvement (V-) received neoadjuvant chemoradiotherapy with S-1 and 50 Gy of radiation as the 5-week regimen. The outcomes of this group were compared with those of 52 patients who underwent S-1 and 30 Gy of radiation as the 2-week regimen, previously collected as our prospective phase II study. RESULTS Compared with the 2-week regimen, there were no significant differences in the rate of protocol completion, adverse events, mortality and morbidity, or R0 resection in the 5-week regimen. In subgroup analyses of R-PDAC, there were no significant differences in overall survival and recurrence-free survival between the groups. In contrast, the 5-week regimen had significantly better overall survival and recurrence-free survival than the 2-week regimen for BRV-PDAC. Similar results were observed after propensity score matching analysis. CONCLUSIONS The 5-week regimen of neoadjuvant chemoradiotherapy has good clinical efficacy and safety for R- and BRV-PDAC. The 5-week regimen could achieve better outcomes than the 2-week regimen for BRV-PDAC. In contrast, both regimens achieved similar outcomes for R-PDAC.

Abstract
The use of neoadjuvant chemoradiation therapy in patients with pancreatic adenocarcinoma is emerg-ing as an acceptable therapy option. The effects of neoadjuvant therapy on 30 days’ outcomes in patients with pancreatic cancer are not well defined in the literature. NSQIP (2009–2012) was used. Only patients with a diagnosis of pancreatic cancer and those who underwent a Whipple were included in the analysis. Patient who underwent neoadjuvant chemoradiation therapy were compared with those who did not receive therapy. Main outcome measures were as follows: complications, ≥2 units of blood transfusions, length of stay, readmission rates, return to the operating room, and 30-day mortality. A total of 1445 patients (395: neoadjuvant chemoradiation and 1050: no neoadjuvant therapy) were identified. The mean age was 67 ± 12 years, and 51 per cent of the patients were male. Neoadjuvant chemoradiation therapy was associated with increase in readmission rates (18% vs 12.2%, P 0.02), unanticipated return to the operating room (2.3% vs 1.1%, P 0.03) with no difference in mortality rates. Neoadjuvant chemoradiation therapy is associated with increase in inhospital complications. These differences in outcomes may be explained by the more advance stage of pancreatic cancer in these subsets of patients. Resource utilization and preoperative rehabilitation are of utmost significance to overcome this rise in complications associated with neoadjuvant chemoradiation therapy.

Abstract
INTRODUCTION The use of neoadjuvant therapy (NAT) for pancreatic cancer is increasing, although its impact on post-operative pancreatic fistula (POPF) is variably reported. This systematic review and meta-analysis aimed to assess the impact of NAT on POPF. METHODS A systematic literature search until October 2019 identified studies reporting POPF following NAT (radiotherapy, chemotherapy or chemoradiotherapy) versus upfront resection. The primary outcome was overall POPF. Secondary outcomes included grade B/C POPF, delayed gastric emptying (DGE), post-operative pancreatic haemorrhage (PPH) and overall and major complications. RESULTS The search identified 24 studies: pancreatoduodenectomy (PD), 19 studies (n = 19 416) and distal pancreatectomy (DP), five studies (n = 477). Local staging was reported in 17 studies, with borderline resectable and locally advanced disease comprising 6% (0-100%) and 1% (0-33%) of the population, respectively. For PD, any NAT was significantly associated with lower rates of overall POPF (OR: 0.57, P < 0.001) and grade B/C POPF (OR: 0.55, P < 0.001). In DP, NAT was not associated with significantly lower rates of overall or grade B/C POPF. CONCLUSION NAT is associated with significantly lower rates of POPF after PD but not after DP. Further studies are required to determine whether NAT should be added to POPF risk calculators.

Abstract
To assess whether the College of American Pathologists (CAP) and the Evans grading systems for neoadjuvant chemotherapy without radiation-treated pancreatectomy specimens are prognostic, and if a 3-tier stratification scheme preserves data granularity. Conducted retrospective review of 32 patients with ordinary pancreatic ductal adenocarcinoma treated with neoadjuvant therapy without radiation followed by surgical resection. Final pathologic tumor category (AJCC eighth edition) was 46.9% ypT1, 34.4% ypT2, and 18.7% ypT3. Median follow-up time was 29.8 months, median disease-free survival (DFS) was 19.6 months, and median overall survival (OS) was 34.2 months. CAP score 1, 2, 3 were present in 5 (15.6%), 18 (56.3%), and 9 (28.1%) patients, respectively. Evans grade III, IIb, IIa, and I were present in 10 (31.2%), 8 (25.0%), 7 (21.9%), and 7 (21.9%) patients, respectively. OS (CAP: P=0.005; Evans: P=0.001) and DFS (CAP: P=0.003; Evans: P=0.04) were statistically significant for both CAP and Evans. Stratified CAP scores 1 and 2 versus CAP score 3 was statistically significant for both OS (P=0.002) and DFS (P=0.002). Stratified Evans grades I, IIa, and IIb versus Evans grade III was statistically significant for both OS (P=0.04) and DFS (P=0.02). CAP, Evans, and 3-tier stratification are prognostic of OS and DFS.

Abstract
BACKGROUND We analyzed the clinical impact of chemotherapy or chemoradiotherapy as initial treatment (IT), focusing on treatment duration, on morbidity and mortality in patients with resected pancreatic ductal adenocarcinoma. METHODS We enrolled 509 consecutive patients, with 417 in the upfront surgery group and 92 in the IT group. The IT group was subdivided into 72 patients treated for <8 months and 20 treated ≥8 months. We compared rates of postoperative Clavien-Dindo grade ≥III complications between the groups. Multivariate logistic regression analysis was used to find independent predictors of complications. RESULTS The upfront surgery and IT groups did not significantly differ in overall postsurgical complications. In contrast, rates of overall complications significantly differed between the <8 months and ≥8 months IT groups, although their background clinical factors did not differ. In multivariate analysis, operative procedure (distal pancreatectomy and distal pancreatectomy with celiac axis resection) (odds ratio [OR] 6.950, P = 0.0416) and IT ≥8 months (OR 4.508, P = 0.0156) were independent predictive factors for postoperative complications. CONCLUSIONS Postoperative complications were significantly higher in the ≥8 months IT group, and multivariate analysis demonstrated that operative procedure and ≥8 months IT were independent predictive factors.

Abstract
BACKGROUND Post-operative pancreatic fistulas remain a significant source of morbidity following pancreatic surgery. Few studies have evaluated the effect of neoadjuvant chemotherapy and radiation on this adverse outcome. This study aims to evaluate the effects of neoadjuvant therapy on 30-day morbidity and mortality following pancreaticoduodenectomy. STUDY DESIGN A retrospective analysis was performed utilizing the targeted pancreas module of the National Surgical Quality Improvement Project (NSQIP) from 2014 to 2015 for patients undergoing pancreaticoduodenectomy with pancreaticojejunal reconstruction. A fistula was defined according to the NSQIP definition. Patient demographics, operative variables, and 30-day outcomes were compared between those who received no neoadjuvant therapy, chemoradiation, chemotherapy alone, and radiation alone. Univariate analysis was completed using chi-square, Fisher exact test, Student's t test, and Mann-Whitney U test where appropriate. Independent predictors of fistula formation were established using multivariable regression. A P value < 0.05 was considered significant. RESULTS Three thousand one hundred fourteen patients were included of which 559 patients (18%) developed a pancreatic fistula. Two thousand six hundred thirty-five (85%) patients did not undergo neoadjuvant therapy, 207 (6.6%) had chemoradiation, 256 (8.2%) had chemotherapy alone, and 16 (0.5%) had radiation alone. Patients who developed a fistula had increased 30-day mortality (4.9 vs. 1.7%, P < .001) and major morbidities. Following multivariable analysis, neoadjuvant radiation (OR 2.1, 95% CI 1.0-4.5) was associated with increased fistula formation while neoadjuvant chemotherapy (OR 0.5, 95% CI 0.3-0.9) was protective. CONCLUSION Neoadjuvant chemotherapy provides protection against the development of pancreatic fistulas while neoadjuvant radiation potentiates formation likely due to their effects on the texture of the pancreatic gland. Given the morbidity of pancreatic fistula formation, these factors should be considered in neoadjuvant regimens.

Meta-analysis comparing upfront surgery with neoadjuvant treatment in patients with resectable or borderline resectable pancreatic cancer. Br J Surg 2018; 105:946-958. [PMID: 29708592 PMCID: PMC6033157 DOI: 10.1002/bjs.10870] [Citation(s) in RCA: 340] [Impact Index Per Article: 56.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2017] [Revised: 11/14/2017] [Accepted: 03/07/2018] [Indexed: 12/11/2022]
Abstract
Background Studies comparing upfront surgery with neoadjuvant treatment in pancreatic cancer may report only patients who underwent resection and so survival will be skewed. The aim of this study was to report survival by intention to treat in a comparison of upfront surgery versus neoadjuvant treatment in resectable or borderline resectable pancreatic cancer. Methods MEDLINE, Embase and the Cochrane Library were searched for studies reporting median overall survival by intention to treat in patients with resectable or borderline resectable pancreatic cancer treated with or without neoadjuvant treatment. Secondary outcomes included overall and R0 resection rate, pathological lymph node rate, reasons for unresectability and toxicity of neoadjuvant treatment. Results In total, 38 studies were included with 3484 patients, of whom 1738 (49·9 per cent) had neoadjuvant treatment. The weighted median overall survival by intention to treat was 18·8 months for neoadjuvant treatment and 14·8 months for upfront surgery; the difference was larger among patients whose tumours were resected (26·1 versus 15·0 months respectively). The overall resection rate was lower with neoadjuvant treatment than with upfront surgery (66·0 versus 81·3 per cent; P < 0·001), but the R0 rate was higher (86·8 (95 per cent c.i. 84·6 to 88·7) versus 66·9 (64·2 to 69·6) per cent; P < 0·001). Reported by intention to treat, the R0 rates were 58·0 and 54·9 per cent respectively (P = 0·088). The pathological lymph node rate was 43·8 per cent after neoadjuvant therapy and 64·8 per cent in the upfront surgery group (P < 0·001). Toxicity of at least grade III was reported in up to 64 per cent of the patients. Conclusion Neoadjuvant treatment appears to improve overall survival by intention to treat, despite lower overall resection rates for resectable or borderline resectable pancreatic cancer. PROSPERO registration number: CRD42016049374. Improved survival with neoadjuvant treatment

World J Surg Oncol 2017; 15:183. [PMID: 29017581 PMCID: PMC5634869 DOI: 10.1186/s12957-017-1240-2] [Citation(s) in RCA: 91] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2017] [Accepted: 08/25/2017] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Recent years have seen standardization of the anatomic definitions of pancreatic adenocarcinoma, and increasing utilization of neoadjuvant therapy (NAT). The aim of the current review was to summarize the evidence for NAT in pancreatic adenocarcinoma since 2009, when consensus criteria for resectable (R), borderline resectable (BR), and locally advanced (LA) disease were endorsed. METHODS PubMed search was undertaken along with extensive backward search of the references of published articles to identify studies utilizing NAT for pancreatic adenocarcinoma. Abstracts from ASCO-GI 2014 and 2015 were also searched. RESULTS A total of 96 studies including 5520 patients were included in the final quantitative synthesis. Pooled estimates revealed 36% grade ≥ 3 toxicities, 5% biliary complications, 21% hospitalization rate and low mortality (0%, range 0-16%) during NAT. The majority of patients (59%) had stable disease. On an intention-to-treat basis, R0-resection rates varied from 63% among R patients to 23% among LA patients. R0 rates were > 80% among all patients who were resected after NAT. Among R and BR patients who underwent resection after NAT, median OS was 30 and 27.4 months, respectively. CONCLUSIONS The current study summarizes the recent literature for NAT in pancreatic adenocarcinoma and demonstrates improving outcomes after NAT compared to those historically associated with a surgery-first approach for pancreatic adenocarcinoma.

Abstract
OPINION STATEMENT Pancreatic cancer surgery is a continuously evolving field. Despite tremendous advances in perioperative outcomes, pancreatic resection is still associated with substantial morbidity, and mortality is not nil. Institutional caseload is a well-established determinant of patient outcomes, and centralization to experienced centers is essential to the safety and oncological appropriateness of the resection. Minimally invasive approaches are increasingly applied for pancreatic resection, even in cancer patients. Nevertheless, the level of evidence in this field remains low. Minimally invasive distal pancreatectomy appears potentially beneficial towards some perioperative outcomes, although its oncological results remain incompletely studied. Data regarding perioperative and oncologic outcomes for minimally invasive pancreaticoduodenectomy (Whipple's resection) is even less mature, but suggest that similar results as the open approach can be achieved in selected, high-volume centers. Conversely, its indiscriminate adoption by inexperienced surgeons and institutions has potential deleterious effects given its steep learning curve. Newer neoadjuvant treatment protocols display enhanced ability to downstage advanced tumors, increasing candidates for potentially curative surgery. Conversely, putative benefits of neoadjuvant treatment in patients with technically resectable tumors have not been reliably demonstrated and its optimal indications remain highly controversial.

Abstract
The management of pancreatic cancer has grown rapidly in the last decade. The Gastrointestinal Tumor Study Group trial in 1985 supported postoperative chemoradiation, and a more recent study recommended 6 months of adjuvant gemcitabine and capecitabine or monotherapy with gemcitabine or fluorouracil plus folinic acid, in the absence of neoadjuvant therapy. Clinicians are now studying the role of targeted therapy in pancreatic cancer and neoadjuvant chemotherapy in resectable, borderline resectable, and locally advanced pancreatic cancer. This article critically evaluates the evolution of pancreatic cancer management, focussing on level 1a, prospective randomized control trials from 2007 to 2017.

The impact of neoadjuvant therapy on the histopathological features of pancreatic ductal adenocarcinoma - A systematic review and meta-analysis. Cancer Treat Rev 2017; 55:96-106. [PMID: 28342938 DOI: 10.1016/j.ctrv.2017.03.003] [Citation(s) in RCA: 71] [Impact Index Per Article: 10.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2017] [Revised: 03/04/2017] [Accepted: 03/06/2017] [Indexed: 12/22/2022]
Abstract
BACKGROUND Due to increased rates of curative tumor resections exceeding 60% after FOLFIRINOX-treatment, neoadjuvant therapy/NTx is increasingly recognized as an effective therapy option for downstaging borderline or locally advanced pancreatic ductal adenocarcinoma/PDAC. Yet, the effects of NTx on the common histopathological features of PDAC have not been systematically analysed. Therefore, the aim of the current study was to assess the impact of NTx on relevant histopathological features of PDAC. PATIENTS AND METHODS Biomedical databases were systematically screened for predefined searching terms related to NTx and PDAC. The Preferred-Reporting-Items-for-Systematic-review-and-Meta-Analysis/PRISMA-guidelines were used to perform a systematic review and meta-analysis. Articles meeting the predefined criteria were analysed on relevance, and a meta-analysis was performed. RESULTS A total of 9031 studies could be identified that analysed the effect of NTx on PDAC. Only 35 studies presented comparative data on the histological features of neoadjuvantly treated vs. upfront resected PDAC patients. In meta-analyses, the beneficial effect of NTx was reflected by reduced tumor size (T1/2: RR 2.87, 95%-CI: 1.52-5.42, P=0.001, T3/4: RR 0.78, 95%-CI: 0.69-0.89, P=0.0002), lower N-Stage (N0: RR 2.14, 95%-CI: 1.85-2.46, P<0.00001, N1: RR 0.59, 95%-CI: 0.53-0.65, P<0.00001), higher R0-rates (R0: RR 1.13, 95%-CI: 1.08-1.18, P<0.00001, R1: RR 0.66, 95%-CI: 0.58-0.76, P<0.00001), less perineural invasion (Pn1: RR 0.78, 95%-CI: 0.73-0.83, P<0.00001), less lymphatic vessel invasion (RR: 0.50, 95%-CI: 0.36-0.70, P<0.0001) and fewer G3-tumors (RR 0.82, 95%-CI: 0.71-0.94, P=0.005). CONCLUSIONS NTx in PDAC seems to exert its beneficial effect in borderline or locally advanced PDAC over genuine tumor downstaging. Thus, although at least 40% of all NTx treated patients remain unresectable even with modern NTx regimes, neoadjuvantly treated PDAC showed not only increasing resectability rates especially after FOLFIRINOX, but even reach a lower tumor stage than primarily resected PDAC.

Preoperative Chemoradiation for Pancreatic Adenocarcinoma Does Not Increase 90-Day Postoperative Morbidity or Mortality. J Gastrointest Surg 2016; 20:1975-1985.

Abstract
BACKGROUND The impact of preoperative chemoradiation on postoperative morbidity and mortality of patients with pancreatic adenocarcinoma remains controversial. METHODS Consecutive pancreatectomies for adenocarcinoma performed between 2011 and 2015 were prospectively monitored for 90 days by using a previously reported surveillance system to determine the association between preoperative chemoradiation and adverse events, pancreatic fistulae, readmissions, and mortality. RESULTS Among 209 consecutive patients who underwent pancreatectomy, 159 (76 %) experienced at least one adverse event within 90 postoperative days. Patients who received preoperative chemoradiation (n = 137, 66 %) were more likely to have borderline resectable/locally advanced tumors, to have received induction chemotherapy, and to require vascular resection at pancreatectomy than those who did not receive chemoradiation (all P < 0.05). Nonetheless, there were no significant differences in the rates of severe complications, readmission, or mortality between these groups (all P > 0.05). Among patients who underwent pancreatoduodenectomy, the rate of pancreatic fistula was similar between those who received chemoradiation and those who did not (P = 0.96). In contrast, those who received chemoradiation prior to distal pancreatectomy had a lower rate of pancreatic fistula (P < 0.01). CONCLUSION Preoperative chemoradiation is not associated with an increase in 90-day morbidity or mortality, and it may reduce the rate of pancreatic fistula following distal pancreatectomy.

Abstract
Borderline resectable pancreatic cancer is now recognized as a distinct clinical entity. In these cases, neoadjuvant treatment could maximize the potential for an R0 resection and avoid R1/R2 resections. In fact, by analyzing, the current literature is evident that approximately one-third of initially borderline resectable pancreatic tumors may undergo successful resection following neoadjuvant therapy. However, the enormous difficulties in achieving a consensus and the variability in therapeutic algorithms have delayed progress in establishing strong evidence-based practices for diagnosis and treatment. In addition, the absence of a unique definition of borderline resectable pancreatic cancer remains a great obstacle for planning a therapeutic strategy and surgical decision-making. If on the one hand, we can finally say that the presence of only few prospective trials generates no strong data to support a specific neoadjuvant therapy regimen in borderline resectable pancreatic cancer, on the other hand, there are many studies on patients with borderline resectable pancreatic cancer who receive neoadjuvant therapy that can enjoy an R0 resection with similar outcomes to up-front resectable disease.

Abstract
BACKGROUND Neoadjuvant multi-agent chemotherapy and stereotactic body radiation therapy (SBRT) are utilized to increase margin negative (R0) resection rates in borderline resectable pancreatic cancer (BRPC) or locally advanced pancreatic cancer (LAPC) patients. Concerns persist that these neoadjuvant therapies may worsen perioperative morbidities and mortality. METHODS Upfront resection patients (n=241) underwent resection without neoadjuvant treatment for resectable disease. They were compared to BRPC or LAPC patients (n=61) who underwent resection after chemotherapy and 5 fraction SBRT. Group comparisons were performed by Mann-Whitney U or Fisher's exact test. Overall Survival (OS) was estimated by Kaplan-Meier and compared by log-rank methods. RESULTS In the neoadjuvant therapy group, there was significantly higher T classification, N classification, and vascular resection/repair rate. Surgical positive margin rate was lower after neoadjuvant therapy (3.3% vs. 16.2%, P=0.006). Post-operative morbidities (39.3% vs. 31.1%, P=0.226) and 90-day mortality (2% vs. 4%, P=0.693) were similar between the groups. Median OS was 33.5 months in the neoadjuvant therapy group compared to 23.1 months in upfront resection patients who received adjuvant treatment (P=0.057). CONCLUSIONS Patients with BRPC or LAPC and sufficient response to neoadjuvant multi-agent chemotherapy and SBRT have similar or improved peri-operative and long-term survival outcomes compared to upfront resection patients.

Abstract
BACKGROUND No consensus exists regarding the optimal neoadjuvant treatment paradigm for patients with borderline resectable pancreatic cancer (BRPC), including the respective roles of chemotherapy and radiation. METHODS We performed a retrospective analysis, including detailed pathologic and radiologic review, of pancreatic cancer patients undergoing FOLFIRINOX, with or without radiation therapy (RT), prior to surgical resection at a high-volume academic center over a 4-year period. RESULTS Of 26 patients meeting inclusion criteria, 22 (84.6%) received FOLFIRINOX alone without RT (median number of treatment cycles = 9). The majority of patients met formal radiographic criteria for BRPC, with the superior mesenteric vein representing the most common vessel involved. R0 resection rate was 90.9%, with 12 patients (54.5%) requiring vascular reconstruction. Treatment response was classified as moderate or marked in 16 patients (72.7%) according to the College of American Pathologists grading system. Estimated median disease-free and overall survival rates are 22.6 months and not reached (NR), respectively. CONCLUSIONS This is one of the largest series to describe the use of neoadjuvant FOLFIRINOX, without radiation therapy, in patients with BRPC undergoing surgical resection. Given the high R0 resection rates and favorable clinical outcomes with chemotherapy alone, this strategy should be further assessed in prospective study design. J. Surg.

Abstract
This review summarizes the current status of neoadjuvant radiation approaches in the treatment of pancreatic cancer, including a description of modern radiation techniques, and an overview on the literature regarding neoadjuvant radio- or radiochemotherapeutic strategies both for resectable and irresectable pancreatic cancer. Neoadjuvant chemoradiation for locally-advanced, primarily non- or borderline resectable pancreas cancer results in secondary resectability in a substantial proportion of patients with consecutively markedly improved overall prognosis and should be considered as possible alternative in pretreatment multidisciplinary evaluations. In resectable pancreatic cancer, outstanding results in terms of response, local control and overall survival have been observed with neoadjuvant radio- or radiochemotherapy in several phase I/II trials, which justify further evaluation of this strategy. Further investigation of neoadjuvant chemoradiation strategies should be performed preferentially in randomized trials in order to improve comparability of the current results with other treatment modalities. This should include the evaluation of optimal sequencing with newer and more potent systemic induction therapy approaches. Advances in patient selection based on new molecular markers might be of crucial interest in this context. Finally modern external beam radiation techniques (intensity-modulated radiation therapy, image-guided radiation therapy and stereotactic body radiation therapy), new radiation qualities (protons, heavy ions) or combinations with alternative boosting techniques widen the therapeutic window and contribute to the reduction of toxicity.

Abstract
BACKGOUND We have treated patients with initially unresectable locally advanced biliary tract cancer (BTC) by administering gemcitabine and have found that surgical resection became feasible in some downsized patients. The aim of this study was to investigate the usefulness of downsizing combination chemotherapy using gemcitabine plus cisplatin to treat initially unresectable locally advanced BTC. METHODS The subjects of the study were 150 consecutive patients who were treated for BTC between October 2011 and April 2014. Downsizing chemotherapy was carried out for 39 patients (26.0 %) whose lesions were unresectable because of locally advanced BTC. RESULTS Reduction in tumor size with downsizing chemotherapy was seen in 18 patients, and surgical resection was performed in 10 of 39 patients (25.6 %). Median survival time in patients with surgical resection following downsizing chemotherapy and those with chemotherapy alone was 17.9 and 12.4 months, respectively (p = 0.0378). According to the historical comparison between gemcitabine and gemcitabine plus cisplatin chemotherapy, there is no significant difference in overall survival. However, there was a significant difference for the pathologic response rate (≥Grade III) to be higher in patients with gemcitabine plus cisplatin chemotherapy compared with gemcitabine monotherapy. CONCLUSIONS Preoperative downsizing chemotherapy with gemcitabine plus cisplatin provides longer survival by the conversion to the surgical resection in patients with initially unresectable locally advanced BTC. It may have the potential for disease eradication as a new multidisciplinary approach for initially unresectable locally advanced BTC.

Optimal indication of neoadjuvant chemoradiotherapy for pancreatic cancer. Langenbecks Arch Surg 2015; 400:477-85. [PMID: 25929828 DOI: 10.1007/s00423-015-1304-0] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2014] [Accepted: 04/20/2015] [Indexed: 02/07/2023]
Abstract
PURPOSE Much attention has been paid to preoperative treatment as a new strategy especially for borderline resectable pancreatic cancer (BRPC). The purpose of this study was to define the optimal indication of neoadjuvant chemoradiotherapy (NACRT) for pancreatic cancer. METHODS We analyzed consecutive 184 patients who had undergone pancreatic resection in Nara Medical University Hospital. Resectability status was classified by NCCN guidelines. Full-dose gemcitabine with concurrent radiation was used as NACRT. We evaluated 85 patients treated with NACRT in comparison with 99 patients without NACRT as control. RESULTS The regimen of NACRT was well tolerated and feasible. The perioperative outcomes were almost comparable. The postoperative complications were significantly less frequent in NACRT group than non-NACRT group. The pathological effects on both resectable and borderline tumors were favorable in NACRT group compared to non-NACRT group. The overall survival of resectable pancreatic cancer was significantly better than that of BRPC regardless of whether the patients were treated with or without NACRT. The prognosis of the patients with NACRT in resectable tumors was significantly better than without, while there was no significant difference in BRPC. Furthermore, multivariate analysis of various factors in the patients with NACRT identified resectability status and completion of adjuvant chemotherapy as independent prognostic factors. CONCLUSIONS NACRT did not improve the prognosis of the patients with BRPC, although it induced substantial pathological antitumor effect. In contrast, the prognosis of resectable pancreatic cancer treated with NACRT was favorable. Therefore, resectable pancreatic cancer may be good indication for multimodal treatment including NACRT.

Abstract
BACKGROUND Much attention has been paid to neoadjuvant treatment (NAT) as a new strategy especially for borderline resectable pancreatic cancer (BRPC). However, the optimal indication of NAT remains undetermined. METHODS We analyzed 248 patients with pancreatic cancer (PC). One hundred resectable tumors were classified as R group. Sixty-nine tumors with venous involvement were classified as BR-P group, while 31 tumors with arterial involvement were classified as BR-A group. Ninety-nine patients received NAT. Furthermore, 48 unresectable locally advanced PC served as controls (LAPC group). Among them, 11 patients received adjuvant surgery afterwards (Ad-surg group). RESULTS The overall median survival time in the R, BR-P and BR-A groups was 45.3, 24.8 and 16.8 months. In the R and BR-P groups, patients treated with NAT had a better prognosis than those without. In contrast, NAT had no impact on prognosis in the BR-A group. Patients treated with NAT in the BR-P, but not BR-A group, had a better prognosis than patients in the LAPC group. Furthermore, patients in the Ad-surg group had a significantly better prognosis than patients in the BR-A group. CONCLUSIONS Borderline resectable pancreatic cancer with venous involvement, but without arterial involvement, may be a good indication for NAT. Our data highlight the importance of preoperative resectability assessment to evaluate the indication and efficacy of NAT.

Does the use of neoadjuvant therapy for pancreatic adenocarcinoma increase postoperative morbidity and mortality rates? J Gastrointest Surg 2015; 19:80-6; discussion 86-7. [PMID: 25091851 PMCID: PMC4289101 DOI: 10.1007/s11605-014-2620-3] [Citation(s) in RCA: 81] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2014] [Accepted: 07/23/2014] [Indexed: 01/31/2023]
Abstract
INTRODUCTION The impact of neoadjuvant therapy on postpancreatectomy complications is inadequately described. METHODS Data from the NSQIP Pancreatectomy Demonstration Project (11/2011 to 12/2012) was used to identify patients with pancreatic adenocarcinoma who did and did not receive neoadjuvant therapy. Neoadjuvant therapy was classified as chemotherapy alone or radiation ± chemotherapy. Outcomes in the neoadjuvant vs. surgery first groups were compared. RESULTS Of 1,562 patients identified at 43 hospitals, 199 (12.7%) received neoadjuvant therapy (99 chemotherapy alone and 100 radiation ± chemotherapy). Preoperative biliary stenting (57.9 vs. 44.7%, p = 0.0005), vascular resection (41.5 vs. 17.3%, p < 0.0001), and open resections (94.0 vs. 91.4%, p = 0.008) were more common in the neoadjuvant group. Thirty-day mortality (2.0 vs. 1.5%, p = 0.56) and postoperative morbidity rates (56.3 vs. 52.8%, p = 0.35) were similar between groups. Neoadjuvant therapy patients had fewer organ space infections (3.0 vs. 10.3%, p = 0.001), and neoadjuvant radiation patients had fewer pancreatic fistulas (7.3 vs. 15.4%, p = 0.03). CONCLUSIONS Despite evidence for more extensive disease, patients receiving neoadjuvant therapy did not experience more complications. Neoadjuvant radiation was associated with lower pancreatic fistula rates. These data provide evidence against higher postoperative complication rates in patients with pancreatic cancer who are treated with neoadjuvant therapy.

Abstract
A major challenge with pancreatic cancer management is in the discrimination of clearly resectable tumors from those that would likely be accompanied by a positive resection margin if upfront surgery was attempted. The standard of care for clearly resectable pancreatic cancer remains surgery followed by adjuvant therapy, but there is considerable controversy over whether such therapeutic adjuvant strategies should include radiotherapy. Furthermore, in a malignancy with such high rates of distant metastasis, investigators are now exploring the feasibility and outcomes of delivering therapy in the neoadjuvant setting, both for clearly resectable as well as borderline resectable tumors. In this review, we explore the current standard of care of upfront surgery for clearly resectable cancers followed by adjuvant therapy, focusing on the role of radiotherapy. We highlight the difficulties in interpreting a literature fraught with inconsistencies in how resectable vs borderline resectable cancers are defined and treated. Finally, we explore the role of neoadjuvant strategies in the modern era.
