High-resolution pancreatic computed tomography for assessing pancreatic ductal adenocarcinoma resectability: a multicenter prospective study. Eur Radiol 2023; 33:5965-5975. [PMID: 36988715 DOI: 10.1007/s00330-023-09584-2] [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: 07/20/2022] [Revised: 02/07/2023] [Accepted: 02/17/2023] [Indexed: 03/30/2023]
Abstract
OBJECTIVE This prospective multicenter study aimed to evaluate the diagnostic performance of 80-kVp thin-section pancreatic CT in determining pancreatic ductal adenocarcinoma (PDAC) resectability according to the recent National Comprehensive Cancer Network (NCCN) guidelines. METHODS We prospectively enrolled surgical resection candidates for PDAC from six tertiary referral hospitals (study identifier: NCT03895177). All participants underwent pancreatic CT using 80 kVp tube voltage with 1-mm reconstruction interval. The local resectability was prospectively evaluated using NCCN guidelines at each center and classified into three categories: resectable, borderline resectable, and unresectable. RESULTS A total of 138 patients were enrolled; among them, 60 patients underwent neoadjuvant therapy. R0 resection was achieved in 103 patients (74.6%). The R0 resection rates were 88.7% (47/53), 52.4% (11/21), and 0.0% (0/4) for resectable, borderline resectable, and unresectable disease, respectively, in 78 patients who underwent upfront surgery. Meanwhile, the rates were 90.9% (20/22), 76.7% (23/30), and 25.0% (2/8) for resectable, borderline resectable, and unresectable PDAC, respectively, in patients who received neoadjuvant therapy. The area under curve of high-resolution CT in predicting R0 resection was 0.784, with sensitivity, specificity, and accuracy of 87.4% (90/103), 48.6% (17/35), and 77.5% (107/138), respectively. Tumor response was significantly associated with the R0 resection after neoadjuvant therapy (odds ratio [OR] = 38.99, p = 0.016). CONCLUSION An 80-kVp thin-section pancreatic CT has excellent diagnostic performance in assessing PDAC resectability, enabling R0 resection rates of 88.7% and 90.9% for patients with resectable PDAC who underwent upfront surgery and patients with resectable PDAC after neoadjuvant therapy, respectively. KEY POINTS • The margin-negative (R0) resection rates were 88.7% (47/53), 52.4% (11/21), and 0.0% (0/4) for resectable, borderline resectable, and unresectable pancreatic ductal adenocarcinoma (PDAC), respectively, on 80-kVp thin-section pancreatic CT in the 78 patients who underwent upfront surgery. • Among the 60 patients who underwent neoadjuvant therapy, the R0 rates were 90.9% (20/22), 76.7% (23/30), and 25.0% (2/8) for resectable, borderline resectable, and unresectable PDAC, respectively. • Tumor response, along with the resectability status on pancreatic CT, was significantly associated with the R0 resection rate after neoadjuvant therapy.

Abstract
BACKGROUND Downstaging has been associated with improved survival for many cancers. However, the implications of downstaging are unclear for pancreatic cancer in an era of effective neoadjuvant systemic chemotherapy. METHODS NCDB retrospective cohort study of resected pancreatic carcinoma treated with neoadjuvant therapy. RESULTS The study included 73,985 patients: 66,589 with no neoadjuvant therapy, 2,102 neoadjuvant radiation therapy (N-RT), 3,195 neoadjuvant multiagent chemotherapy (N-MAC) and 2.099 with both neoadjuvant radiation and multiagent chemotherapy. There was increased use of N-MAC over the period of this study. Patients selected for treatment with N-MAC had longer survival from surgery on univariate (23.1 vs. 18.7 months, p = < 0.01) and multivariate analyses HR 0.81 (0.76-0.87, p < 0.001) compared to those selected with N-RT. Downstaging was similar in N-RT and N-MAC groups (25.1 vs. 24.1%, p = 0.43). Downstaging following N-MAC was associated with a survival benefit, HR 0.85 (0.74-0.98). However, downstaging following N-RT was not associated with a survival advantage, HR 1.12 (0.99-0.99). CONCLUSION Clinicians have rapidly adopted N-MAC for treatment of pancreatic cancer. Although the rates of downstaging are similar between treatment groups, response translates into increased survival only with N-MAC and not with N-RT.

Downstaging of Pancreatic Adenocarcinoma With Either Neoadjuvant Chemotherapy or Chemoradiotherapy Improves Survival. Ann Surg Oncol 2022; 29:6015-6028. [PMID: 35583691 DOI: 10.1245/s10434-022-11800-0] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2021] [Accepted: 04/05/2022] [Indexed: 12/23/2022]
Abstract
BACKGROUND Neoadjuvant chemotherapy (NAC) or chemoradiation (NAC+XRT) is incorporated into the treatment of localized pancreatic adenocarcinoma (PDAC), often with the goal of downstaging before resection. However, the effect of downstaging on overall survival, particularly the differential effects of NAC and NAC+XRT, remains undefined. This study examined the impact of downstaging from NAC and NAC+XRT on overall survival. METHODS The National Cancer Data Base (NCDB) was queried from 2006 to 2015 for patients with non-metastatic PDAC who received NAC or NAC+XRT. Rates of overall and nodal downstaging, and pathologic complete response (pCR) were assessed. Predictors of downstaging were evaluated using multivariable logistic regression. Overall survival (OS) was assessed with Kaplan-Meier and Cox proportional hazards modeling. RESULTS The study enrolled 2475 patients (975 NAC and 1500 NAC+XRT patients). Compared with NAC, NAC+XRT was associated with higher rates of overall downstaging (38.3 % vs 23.6 %; p ≤ 0.001), nodal downstaging (16.0 % vs 7.8 %; p ≤ 0.001), and pCR (1.7 % vs 0.7 %; p = 0.041). Receipt of NAC+XRT was independently predictive of overall (odds ratio [OR] 2.28; p < 0.001) and nodal (OR 3.09; p < 0.001) downstaging. Downstaging by either method was associated with improved 5-year OS (30.5 vs 25.2 months; p ≤ 0.001). Downstaging with NAC was associated with an 8-month increase in median OS (33.7 vs 25.6 months; p = 0.005), and downstaging by NAC+XRT was associated with a 5-month increase in median OS (30.0 vs 25.0 months; p = 0.008). Cox regression showed an association of overall downstaging with an 18 % reduction in the risk of death (hazard ratio [HR] 0.82; 95 % confidence interval, 0.71-0.95; p = 0.01) CONCLUSION: Downstaging after neoadjuvant therapies improves survival. The addition of radiation therapy may increase the rate of downstaging without affecting overall oncologic outcomes.

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.

Systematic review and meta-analysis of diagnostic performance of CT imaging for assessing resectability of pancreatic ductal adenocarcinoma after neoadjuvant therapy: importance of CT criteria. Abdom Radiol (NY) 2021; 46:5201-5217. [PMID: 34331549 DOI: 10.1007/s00261-021-03198-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/23/2021] [Revised: 06/23/2021] [Accepted: 06/26/2021] [Indexed: 02/07/2023]
Abstract
PURPOSE To assess the CT diagnostic performance for evaluating resectability of pancreatic ductal adenocarcinoma (PDAC) after neoadjuvant therapy and identify the factor(s) that affect(s) diagnostic performance. METHODS Databases were searched to identify studies published from January 1, 2000, to November 5, 2019 that evaluated the CT diagnostic performance for assessing resectability of post-neoadjuvant PDAC. Two reviewers independently extracted data and assessed the study quality. A meta-analysis was performed to obtain summary sensitivity and specificity values using a bivariate random-effects model, and heterogeneity across studies was assessed. Univariable meta-regression analysis was performed with eight variables, including the different CT criteria for resectability, conventional National Comprehensive Cancer Network (NCCN) criteria for upfront surgery, and modified criteria for post-neoadjuvant surgery. RESULTS Ten studies were included and analyzed. The summary sensitivity and specificity for resectability were 78% (95% CI 68-86%) and 60% (95% CI 44-74%), respectively. No significant heterogeneity was identified (bivariate correlation coefficient ρ = - 1, p-value for hierarchical summary receiver operating characteristics model β = 0.667). The two different CT criteria showed different diagnostic performance (p < 0.01), with higher sensitivity (81% [95% CI 73-90%] vs. 28% [95% CI 15-42%], p < 0.01) and lower specificity (57% [95% CI 41-73%] vs. 90% [95% CI 80-100%], p < 0.01) for the modified criteria. No other variables affected the diagnostic performance. CONCLUSION CT criteria were the factors that affected the diagnostic performance. Modification of the conventional criteria improved sensitivity but lowered specificity. Further modifications are required to improve specificity and uniformity.

Abstract
OBJECTIVES To investigate clinical and CT factors associated with local resectability in patients with nonmetastatic pancreatic cancers after neoadjuvant chemotherapy ± radiation therapy (CRT). METHODS This retrospective study included consecutive patients with nonmetastatic pancreatic cancers who underwent neoadjuvant CRT between June 2009 and June 2019. Tumor size, tumor-vascular contact with artery/vein, and local resectability categories (resectable, borderline resectable, or locally advanced) were assessed at baseline and post-CRT CT. Baseline and post-CRT carbohydrate antigen (CA) 19-9 levels were also assessed. Clinical or imaging features related to R0 resection were determined using logistic regression analysis. RESULTS A total of 179 patients (mean age, 62.4 ± 9.3 years; 92 men) were included. After neoadjuvant CRT, 105 (58.7%) patients received R0 resection, while 74 (41.3%) did not. R0 resection rates were significantly different according to post-CRT CT resectability categories (p < 0.001): 82.8% (48/58), 70.1% (47/67), and 18.5% (10/54) for resectable, borderline resectable, and locally advanced disease, respectively. For post-CRT borderline resectable disease, ≥ 50% decrease in CA 19-9 was significantly associated with R0 resection (odds ratio (OR), 3.160; p = 0.02). For post-CRT locally advanced disease, small post-CRT tumor size ≤ 2 cm (OR, 9.668; p = 0.026) and decreased tumor-arterial contact (OR, 24.213; p = 0.022) were significantly associated with R0 resection. CONCLUSION Post-CRT CT resectability categorization may be useful for the assessment of R0 resectability in patients with pancreatic cancer following neoadjuvant CRT. Additionally, ≥ 50% decrease in CA 19-9 was associated with R0 resection in post-CRT borderline resectable disease, while small post-CRT tumor size and decreased tumor-arterial contact were with locally advanced disease. KEY POINTS • R0 resection rates following neoadjuvant chemotherapy ± radiation therapy (CRT) were 82.8%, 70.1%, and 18.5% in resectable, borderline resectable, and locally advanced disease, respectively, at post-CRT CT (p < 0.001). • For post-CRT borderline resectable disease, ≥ 50% decrease in carbohydrate antigen (CA) 19-9 was significantly associated with R0 resection. • For post-CRT locally advanced disease, small post-CRT tumor size ≤ 2 cm and decreased tumor-arterial contact were significantly associated with R0 resection.

Is Neoadjuvant Treatment Justified in Clinical T1 Pancreatic Ductal Adenocarcinoma? J Clin Med 2021; 10:jcm10040873. [PMID: 33672686 PMCID: PMC7924368 DOI: 10.3390/jcm10040873] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Revised: 02/09/2021] [Accepted: 02/15/2021] [Indexed: 11/17/2022] Open
Abstract
Introduction: Studies on neoadjuvant treatment have been actively conducted in patients with resectable pancreatic cancer. However, neoadjuvant treatment effectiveness, especially in clinical T1 stage patients, still needs to be determined. We comparatively evaluated the oncologic benefit of preoperative neoadjuvant treatment in clinical T1 stage pancreatic cancer. Methods: Data from two centers were included in the comparative analysis, with overall and recurrence-free survival as primary outcomes, between January 2010 and December 2017. Results: In total, 45 patients were retrospectively reviewed in this study. Two patients in the neoadjuvant group were excluded because of distant metastasis during neoadjuvant treatment. Finally, 43 patients underwent a pancreatectomy for clinical T1 pancreatic cancer, of whom, 35 and 8 patients underwent upfront surgery and neoadjuvant treatment, respectively. Overall survival was similar in the two study groups (5-year overall survival rate: neoadjuvant group, 75%; upfront surgery group, 43.9%, p = 0.066). Conclusions: In our study on patients with clinical T1 stage pancreatic cancer, no significant differences were reported in the oncological outcome in the neoadjuvant therapy group. Large-scale prospective studies are needed to determine the survival benefits of neoadjuvant treatment for early-stage pancreatic cancer.

Abstract
BACKGROUND AND AIMS Locally advanced pancreatic cancer (LAPC) is challenging. Here, we aimed to evaluate the tolerability and safety of Ad5-yCD/mutTK(SR39)rep-ADP (Ad5-DS), a replication-competent adenovirus-mediated double-suicide gene therapy in combination with gemcitabine in patients with LAPC. METHODS Patients with newly diagnosed LAPC were enrolled in this single-center, open-label, 3 + 3 dose-escalation phase 1 trial. Ad5-DS was injected into the pancreatic mass with EUS-guided fine needles combined with oral 5-fluorocytosine and valganciclovir, and a standard dose of intravenous gemcitabine. The doses of Ad5-DS in cohorts 1 to 3 were 1 × 1011, 3 × 1011, and 1 × 1012 viral particles (vp)/mL, respectively. Patients were observed for dose-limiting toxicity (DLT) for 8 weeks after Ad5-DS injection. Toxicity within 12 weeks, tumor response in 12 weeks, disease progression in 6.5 months, and detection of adenoviral DNA particles in 8 weeks were also assessed. RESULTS Among the 11 enrolled patients, 9 completed the evaluation period and 2 withdrew their consent. No DLT was reported; thus, the maximum tolerated dose was not reached. No additional toxicity was reported in 9 to 12 weeks. One patient showed a partial response and 8 showed stable disease at 12 weeks. Two patients showed disease progression at 6.5 months (median progression-free survival, 11.4 months). At 8 weeks, serum adenoviral DNA particles were detected in 4 patients (median, 55 days). CONCLUSION A combination of intratumoral Ad5-DS and gemcitabine is safe and well tolerated in patients with LAPC. This warrants further investigation in a larger clinical trial. (Clinical trial registration number: NCT02894944.).

Front Genet 2020; 11:554502. [PMID: 33193628 PMCID: PMC7593847 DOI: 10.3389/fgene.2020.554502] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Accepted: 08/17/2020] [Indexed: 12/20/2022] Open
Abstract
Background Pancreatic ductal adenocarcinoma (PDAC) is the most aggressive form of pancreatic cancer. Its 5-year survival rate is only 3–5%. Perineural invasion (PNI) is a process of cancer cells invading the surrounding nerves and perineural spaces. It is considered to be associated with the poor prognosis of PDAC. About 90% of pancreatic cancer patients have PNI. The high incidence of PNI in pancreatic cancer limits radical resection and promotes local recurrence, which negatively affects life quality and survival time of the patients with pancreatic cancer. Objectives To investigate the mechanism of PNI in pancreatic cancer, we analyzed the gene expression profiles of tumors and adjacent tissues from 50 PDAC patients which included 28 patients with perineural invasion and 22 patients without perineural invasion. Method Using Monte-Carlo feature selection and Incremental Feature Selection (IFS) method, we identified 26 key features within which 15 features were from tumor tissues and 11 features were from adjacent tissues. Results Our results suggested that not only the tumor tissue, but also the adjacent tissue, was informative for perineural invasion prediction. The SVM classifier based on these 26 key features can predict perineural invasion accurately, with a high accuracy of 0.94 evaluated with leave-one-out cross validation (LOOCV). Conclusion The in-depth biological analysis of key feature genes, such as TNFRSF14, XPO1, and ATF3, shed light on the understanding of perineural invasion in pancreatic ductal adenocarcinoma.

Abstract
OBJECTIVE For many patients whose pancreatic ductal adenocarcinoma (PDAC) is locally advanced, neoadjuvant therapy has been proposed as a way to decrease tumor burden. Pancreatic ductal adenocarcinoma is generally thought to be resistant to chemotherapy and radiation, however, response to neoadjuvant therapy in PDAC has been described in a subset of patients. The SMAD4 status is considered to be an important molecular feature which distinguishes two subsets of PDAC, SMAD4-positive and -negative tumors. The objective of this study was to evaluate the neoadjuvant treatment response rate as well as compare the different clinicopathologic variables between SMAD4-positive and -negative tumors. METHODS We analyzed the data of patients who underwent surgical resection for PDAC from 2009-2019. Our cohort from a single institution included 233 patients. RESULTS Of the 233 cases, 143 (61.4%) were SMAD4-negative and 90 (38.6%) were SMAD4-positive. Overall, SMAD4-positive tumors with neoadjuvant therapy had better treatment response and better tumor regression scores. In addition, SMAD4-positive tumors had a significantly lower lymph node metastasis rate in both the neoadjuvant and nonneoadjuvant setting. CONCLUSIONS Further characterization of the role of SMAD4 within the context of neoadjuvant therapy will lead to improved personalized therapeutic strategies.

Abstract
Neoadjuvant treatment (NT) for pancreatic head cancer may allow some patients to undergo curative resection, but its impact on postoperative complications remains unclear. A systematic review and meta-analysis were performed to compare overall postoperative morbidity, pancreatic fistula, and mortality between patients who underwent upfront surgery and those who underwent neoadjuvant therapy first. Forty-five studies with 3359 patients were included. No significant differences in morbidity and mortality rates associated with NT for pancreatic head cancer were detected in this study.

Abstract
OBJECTIVE The aim of this study was to determine (1) whether preoperative factors can predict resectability of borderline resectable (BR) and locally advanced (LA) pancreatic ductal adenocarcinoma (PDAC) after neoadjuvant FOLFIRINOX, (2) which patients might benefit from adjuvant therapy, and (3) survival differences between resected BR/LA patients who received neoadjuvant FOLFIRINOX and upfront resected patients. BACKGROUND Patients with BR/LA PDAC are often treated with FOLFIRINOX to obtain a margin-negative resection, yet selection of patients for resection remains challenging. METHODS Clinicopathologic data of PDAC patients surgically explored between 04/2011-11/2016 in a single institution were retrospectively collected. RESULTS Following neoadjuvant FOLFIRINOX, 141 patients were surgically explored (BR: 49%, LA: 51%) and 110 (78%) were resected. Resected patients had lower preoperative CA 19-9 levels (21 vs 40 U/mL, P = 0.03) and smaller tumors on preoperative computed tomography (CT) scan (2.3 vs 3.0 cm, P = 0.03), but no predictors of resectability were identified. Median overall survival (OS) was 34.2 months from diagnosis for all FOLFIRINOX patients and 37.7 months for resected patients. Among resected patients, preoperative CA 19-9 >100 U/mL and >8 months between diagnosis and surgery predicted a shorter postoperative disease-free survival (DFS); Charlson comorbidity index >1, preoperative CA 19-9 >100 U/mL and tumor size (>3.0 cm on CT or >2.5 cm on pathology) predicted decreased OS. DFS and OS were significantly better for BR/LA PDAC patients treated with neoadjuvant FOLFIRINOX compared with upfront resected patients (DFS: 29.1 vs 13.7, P < 0.001; OS: 37.7 vs 25.1 months from diagnosis, P = 0.01). CONCLUSION BR/LA PDAC patients with no progression on neoadjuvant FOLFIRINOX should be offered surgical exploration. Except size, traditional pathological parameters fail to predict survival among resected FOLFIRINOX patients. Resected FOLFIRINOX patients have survival that appears to be superior than that of resectable patients who go directly to surgery.

Abstract
RATIONALE Total pancreatectomy (TP) is performed in cases of multifocal and large invasive tumors of the pancreas, and is associated with high rates of mortality and morbidity. Previously, the limitations and unsatisfactory effect of this surgery rendered it rarely performed; however, with improvements in surgical techniques and blood sugar management, TP is now more frequently performed. TP has a similar long-term survival rate as that for pancreatoduodenectomy (PD). However, the application of TP plus total gastrectomy (TG) for the treatment of invasive pancreatic ductal adenocarcinoma has not been reported previously. PATIENT CONCERNS The patient was a 64-year-old man with epigastric discomfort. Physical examination showed a hard mass. Preoperative computed tomography and magnetic resonance imaging revealed a solid mass located in the pancreatic body and involving the portal vein and stomach. DIAGNOSIS Pancreatic cancer. INTERVENTIONS The patient was treated with TP combined with TG and portal vein reconstruction. OUTCOMES The patient had a smooth post-operative recovery but, regretfully, developed metastases 2 months after discharge. LESSONS Considering the poor outcome of the present case, the validity of the operation should be reevaluated. Although a single case does not elicit a convincing conclusion, the current case might serve as a warning against performing a similar surgery.

Abstract
BACKGROUND Pancreatic ductal adenocarcinoma remains a disease with a poor prognosis despite advances in surgery and systemic therapies. Neoadjuvant therapy strategies are a promising alternative to adjuvant chemotherapy. However, their role remains controversial. This meta-analysis aims to clarify the benefits of neoadjuvant therapy in resectable pancreatic ductal adenocarcinoma. METHODS Eligible studies were identified from MEDLINE, Embase, Web of Science and the Cochrane Library. Studies comparing neoadjuvant therapy with a surgery first approach (with or without adjuvant therapy) in resectable pancreatic ductal adenocarcinoma were included. The primary outcome assessed was overall survival. A random-effects meta-analysis was performed, together with pooling of unadjusted Kaplan-Meier curve data. RESULTS A total of 533 studies were identified that analysed the effect of neoadjuvant therapy in pancreatic ductal adenocarcinoma. Twenty-seven studies were included in the final data synthesis. Meta-analysis suggested beneficial effects of neoadjuvant therapy with prolonged survival compared with a surgery-first approach, (hazard ratio 0.72, 95% confidence interval 0.69-0.76). In addition, R0 resection rates were significantly higher in patients receiving neoadjuvant therapy (relative risk 0.51, 95% confidence interval 0.47-0.55). Individual patient data analysis suggested that overall survival was better for patients receiving neoadjuvant therapy (P = 0.008). CONCLUSIONS Current evidence suggests that neoadjuvant chemotherapy has a beneficial effect on overall survival in resectable pancreatic ductal adenocarcinoma in comparison with upfront surgery and adjuvant therapy. Further trials are needed to address the need for practice change.

Abstract
Pancreatic adenocarcinoma remains one of the most aggressive cancers with an ongoing dismal survival rate despite some recent advances in treatment options. This is largely due to the typically late presentation and limited effective therapeutic options in advanced disease. There are numerous circulating biomarkers that have potential clinical application as tumour markers, including circulating tumour DNA (ctDNA), circulating tumour cells (CTCs), cell-free RNA (cfRNA), exosomes and circulating tumour proteins. This review will focus on the development of ctDNA as a non-invasive liquid biopsy, with its high sensitivity and specificity having potential clinical applications in pancreatic cancer. These include a role in screening, prognostication via the detection of minimal residual disease, early detection of recurrence, and for patients with advanced disease; tumour genotyping and monitoring treatment response. Prospective randomised adjuvant clinical trials are currently underway, exploring the impact of ctDNA-guided adjuvant therapy decisions. In this review, we provide perspectives on the current literature and considerations of future directions.

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 Neoadjuvant therapy (NAT) for pancreatic adenocarcinoma (PDAC) patients has shown promising results in non-randomized trials. This is a multi-institutional phase II trial of NAT in resectable PDAC patients. METHODS Patients with confirmed resectable PDAC after agreement by two expert radiologists were eligible. Patients received three cycles of GEM (1000 mg/m2/week) plus daily erlotinib (ERL) (100 mg/day). After re-staging, patients without progressive disease underwent 5 weeks of therapy with GEM (300 mg/m2/week), ERL 100 mg/day and concomitant radiotherapy (45 Gy). Efficacy was assessed using tumor regression grade (TRG) and resection margin status. Using a single-arm Simon's design, considering the therapy not useful if R0 < 40% and useful if the R0 > 70% (alpha 5%, beta 10%), 24 patients needed to be recruited. This trial was registered at ClinicalTrials.gov, number NCT01389440. RESULTS Twenty-five patients were enrolled. Adverse effects of NAT were mainly mild gastrointestinal disorders. Resectability rate was 76%, with a R0 rate of 63.1% among the resected patients. Median overall survival (OS) and disease-free survival (DFS) were 23.8 (95% CI 11.4-36.2) and 12.8 months (95% CI 8.6-17.1), respectively. R0 resection patients had better median OS, compared with patients with R1 resection or not resected (65.5 months vs. 15.5 months, p = 0.01). N0 rate among the resected patients was 63.1%, and showed a longer median OS (65.5 vs. 15.2 months, p = 0.009). CONCLUSION The results of this study confirm promising oncologic results with NAT for patients with resectable PDAC. Therefore, the present trial supports the development of phase II randomized trials comparing NAT vs. upfront surgery in resectable pancreatic cancer.

Abstract
BACKGROUND At time of diagnosis, less than 10% of patients with pancreatic adenocarcinomas (PDAC) are considered to be immediately operable (i.e. resectable). Considering their poor overall survival (OS), only tumours without vascular invasion (NCCN 2017) should be considered for resection, i.e. those for which resection with disease-free margins (R0) is theoretically possible in absence of presurgery treatment. With regard to high R1 rates and undetectable locoregional and/or metastatic spreading prior to surgery explain (at least in part) the observed 1-year relapse and mortality rates of 50 and 25%, respectively. Today, upfront surgery followed by adjuvant chemotherapy is the reference treatment in Europe. The main limitation of the adjuvant approach is the low rate of completion of the full therapeutic sequence. Indeed, only 47 to 60% patients received any adjuvant therapy after resection compared to more than 75% for neoadjuvant therapy. No previous prospective study has compared this approach to a neoadjuvant FOLFIRINOX or FOLFOX chemotherapy for resectable PDAC. METHODS PANACHE01-PRODIGE48 is a prospective multicentre controlled randomized non comparative Phase II trial, evaluating the safety and efficacy of two regimens of neo-adjuvant chemotherapy (4 cycles of mFOLFIRINOX or FOLFOX) relative to the current reference treatment (surgery and then adjuvant chemotherapy) in patients with resectable PDAC. The main co-primary endpoints are OS rate at 12 months and the rate of patients undergoing the full therapeutic sequence. DISCUSSION The "ideal" cancer treatment for resectable PDAC would have the following characteristics: administration to the highest possible proportion of patients, ability to identify fast-progressing patients (i.e. poor candidates for surgery), a low rate of R1 resections (through optimisation of local disease control), and an acceptable toxicity profile. The neoadjuvant approach may meet all these criteria. With respect to published data on the efficacy of FOLFOX and mFOLFIRINOX, these two regimens are potential candidates for neoadjuvant use in the aim to optimising oncological outcomes in resectable PDAC.

Abstract
Since the advent of modern surgery for pancreatic cancer, clinicians have recognized this cancer's propensity to recur locally, metastasize, and cause death. Despite significant efforts to improve patient outcomes with better adjuvant therapy, only modest gains in survival have been observed. An alternative strategy of neoadjuvant therapy followed by surgery has the potential to improve patient selection and survival, and expand the pool of patients eligible for curative surgery. This article summarizes large, randomized trials of adjuvant therapy, explains the limitations imposed by up-front surgery, and suggests neoadjuvant therapy as a rational alternative to initial surgery and adjuvant therapy.

Abstract
PURPOSE To determine the accuracy and safety of the percutaneous biopsy of pancreatic mass lesions. MATERIALS AND METHODS Over a 12-year period clinical parameters, imaging, pathologic results, and complications were assessed in patients undergoing percutaneous biopsies pancreatic lesions. RESULTS One hundred fifty-three patients underwent pancreatic biopsy. The preferred modality for performing the biopsy was ultrasound (93%, n=143) followed by computerized tomography (7%, n=10). Histologic diagnosis was achieved in 147 patients, of which 3 (2%) were benign and 144 (94%) were malignant. Complications included a single death from overwhelming hemorrhage and 2 patients with morbidity (hematoma and cerebrovascular accident). The sensitivity and specificity of percutaneous biopsies was 90% and 95%, respectively. CONCLUSIONS Ultrasound-guided and computerized tomographic-guided percutaneous biopsy of pancreatic lesions is an effective and safe method to confirm or refute malignancy in suspicious pancreatic lesions. Endoscopic ultrasound-guided Tru-Cut may have the added advantage of avoiding the risk of peritoneal soiling.

Preoperative Chemoradiation for Pancreatic Adenocarcinoma Does Not Increase 90-Day Postoperative Morbidity or Mortality. J Gastrointest Surg 2016; 20:1975-1985. [PMID: 27730398 DOI: 10.1007/s11605-016-3286-9] [Citation(s) in RCA: 35] [Impact Index Per Article: 4.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/01/2016] [Accepted: 09/20/2016] [Indexed: 01/31/2023]
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
OBJECTIVES We aimed to identify risk factors for latent distant organ metastasis in patients with radiographically defined locally advanced (RDLA) pancreatic ductal adenocarcinoma (PDAC). METHODS RDLA disease was defined as unresectable disease without distant organ metastasis based on resectability status by NCCN guidelines. Between January 2005 and November 2015, 110 consecutive patients underwent staging laparoscopy to rule out latent distant metastasis. Univariate and multivariate analyses were performed to identify risk factors for latent distant organ metastasis or peritoneal metastasis (PM), defined as peritoneal dissemination and/or positive peritoneal lavage cytology (PPC). RESULTS Latent distant organ metastasis was diagnosed by staging laparoscopy in 62 patients. PPC was found in 23%, peritoneal dissemination in 19%, and liver metastasis in 15%. Univariate analysis showed tumor location, preoperative CA 19-9 level and tumor size, and multivariate analysis revealed tumor size >55 mm and CA 19-9 level >60 IU/ml as risk factors for latent distant metastasis. Multivariate analysis showed pancreas body-tail tumors and tumor size >42 mm as risk factors for PM; 65.4% of pancreas body-tail tumors >42 mm had PM. CONCLUSIONS Patients with large pancreas body-tail tumors and high CA 19-9 level are at greater risk for latent distant organ metastasis or PM, and should undergo staging laparoscopy routinely for accurate diagnosis (UMIN000023125).

Abstract
BACKGROUND Neoadjuvant therapy is an emerging paradigm in pancreatic cancer care; however, its role for resectable disease remains controversial in the absence of conclusive randomized controlled trials. The purpose of the present study is to assess the impact of neoadjuvant therapy on survival in resected pancreatic cancer patients by clinical stage. METHODS A retrospective cohort study using the National Cancer Data Base from 2004 to 2012 including nonmetastatic pancreatic adenocarcinoma patients who underwent pancreatectomy and initiated chemotherapy. Propensity score matching within each stage was used to account for potential selection bias between patients undergoing neoadjuvant therapy and upfront surgery. Overall survival was compared by the Kaplan-Meier method. RESULTS In the study, 1,541 and 7,159 patients received neoadjuvant therapy followed by surgery and upfront surgery succeeded by adjuvant therapy, respectively. In clinical stage III pancreatic cancer (n = 486), neoadjuvant therapy was associated with significant survival benefit after matching (median survival 22.9 vs 17.3 months; log-rank P < .0001) compared with conventional upfront surgery followed by adjuvant therapy; however, no survival difference was found between the 2 treatment sequences in patients with clinical stage I (n = 3,149; median survival, 26.2 vs 25.7 months; P = .4418) and II (n = 5,065; median survival, 23.5 vs 23.0 months; P = .7751) disease after matching. CONCLUSION The survival impact of neoadjuvant therapy is stage-dependent. Neoadjuvant therapy does not disadvantage survival compared with conventional upfront surgery followed by adjuvant therapy in any stage, and is associated with a significant survival advantage in stage III pancreatic cancer.

Abstract
BACKGROUND Pancreatic cancer is among the top 5 most common cancers worldwide, but is particularly devastating due to its insidious nature. Complete surgical resection remains the only potential curative treatment, although only 20 % of patients present with a resectable tumor. Patients may alternatively present with borderline resectable pancreatic cancer or locally advanced pancreatic cancer and can be offered treatment with neoadjuvant intent. The effectiveness of these treatments is unclear and there is a paucity of data to suggest one optimal treatment approach. CASE PRESENTATION We describe a 61-year-old female who presented with a two-week history of obstructive jaundice in the context of vague abdominal pain that had been ongoing for years prior to her visit. CT scan of the abdomen confirmed a hypovascular mass in the uncinate process consistent with borderline resectable pancreatic cancer. Pancreatic adenocarcinoma was confirmed with endoscopic ultrasound guided fine-needle aspiration cytology. Following multidisciplinary discussion, it was recommended that she undergo treatment with FOLFIRINOX. After a total of 13 cycles, follow up CT revealed that the lesion had decreased in size and she was offered resection as a potentially curative treatment. She underwent pancreaticoduodenectomy. Final pathology report revealed no evidence of residual adenocarcinoma (ypT0 ypN0 (0/23)). The patient remains disease-free 15 months following surgery. CONCLUSION To date, there have been very few reports of a complete pathological response following neoadjuvant therapy in borderline resectable or locally advanced pancreatic cancer. This report describes a unique case of a complete pathological remission in a patient with borderline resectable pancreatic cancer following FOLFIRINOX therapy alone and adds to the growing base of evidence meriting the initiation of clinical trials to assess the efficacy of FOLFIRINOX in these subsets of pancreatic cancer.

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 The value of neoadjuvant chemotherapy in the treatment of early stage pancreatic cancer is not yet clear. METHODS We evaluated patients from the National Cancer Data Base who underwent pancreaticoduodenectomy for clinical stage I and II pancreatic adenocarcinoma between 2006 and 2012. RESULTS In total, 7,881 patients were identified. Of these, 27.5% received no chemotherapy, 57.4% received adjuvant chemotherapy, 10.2% received neoadjuvant chemotherapy alone, and 4.9% received perioperative chemotherapy, both preoperative and postoperative chemotherapy. Neoadjuvant chemotherapy use (neoadjuvant chemotherapy alone and perioperative chemotherapy) increased from 12.0% in 2006 to 20.2% in 2012. Patients who received chemotherapy prior to the operation (neoadjuvant chemotherapy alone and perioperative chemotherapy) had greater rates of margin negative (80.2% vs 73.0%, P < .001) and node negative (58.2% vs 28.7%, P < .001) resections and shorter mean durations of stay (12.0 vs 11.1 days, P = .012) than those receiving either adjuvant chemotherapy or no chemotherapy at all. There were no differences in 30-day unplanned readmissions (P = .074) and 90-day mortality (P = .227). On Cox survival analysis, adjusted for clinical variables including age and comorbid disease, patients undergoing perioperative chemotherapy, adjuvant chemotherapy, and neoadjuvant chemotherapy alone demonstrated significantly improved overall survival relative to that of patients undergoing resection alone (all P < .001). Patients receiving perioperative chemotherapy demonstrated a significant overall survival advantage compared with those receiving adjuvant chemotherapy (hazard ratio 0.75; 95% confidence interval, 0.65-0.85). Neoadjuvant chemotherapy alone had a marginal overall survival benefit compared with adjuvant chemotherapy (hazard ratio 0.89; 95% confidence interval, 0.81-0.98). CONCLUSION Early stage pancreatic cancer patients who receive perioperative chemotherapy have better overall survival than those receiving no chemotherapy, adjuvant chemotherapy, or neoadjuvant chemotherapy alone. Patterns of postoperative morbidity are similar regardless of the sequence of therapy. Neoadjuvant chemotherapy should be considered for patients presenting with early stage pancreatic cancer.

Abstract
Controversy remains regarding neoadjuvant approaches in the treatment of pancreatic cancer. Neoadjuvant therapy has several potential advantages over adjuvant therapy including earlier delivery of systemic treatment, in vivo assessment of response, increased resectability rate in borderline resectable patients and increased margin-negative resection rate. At present, there are no randomized data favoring neoadjuvant over adjuvant therapy and multiple neoadjuvant approaches are under investigation. Combination chemotherapy regimens including 5-fluorouracil, irinotecan and oxaliplatin, gemcitabine with or without abraxane, or docetaxel and capecitabine have been used in the neoadjuvant setting. Radiation and chemoradiation have also been incorporated into neoadjuvant strategies, and delivery of alternative fractionation regimens is being explored. This review provides an overview of neoadjuvant therapies for pancreatic cancer.

Abstract
BACKGROUND To identify indications for staging laparoscopy (SL) in patients with resectable pancreatic cancer, and suggest a pre-operative algorithm for staging these patients. METHODS Relevant articles were reviewed from the published literature using the Medline database. The search was performed using the keywords 'pancreatic cancer', 'resectability', 'staging', 'laparoscopy', and 'Whipple's procedure'. RESULTS Twenty four studies were identified which fulfilled the inclusion criteria. Of the published data, the most reliable surrogate markers for selecting patients for SL to predict unresectability in patients with CT defined resectable pancreatic cancer were CA 19.9 and tumour size. Although there are studies suggesting a role for tumour location, CEA levels, and clinical findings such as weight loss and jaundice, there is currently not enough evidence for these variables to predict resectability. Based on the current data, patients with a CT suggestive of resectable disease and (1) CA 19.9 ≥150 U/mL; or (2) tumour size >3 cm should be considered for SL. CONCLUSION The role of laparoscopy in the staging of pancreatic cancer patients remains controversial. Potential predictors of unresectability to select patients for SL include CA 19.9 levels and tumour size.

Abstract
BACKGROUND/OBJECTIVES This study examined main pancreatic ductal spread in invasive ductal adenocarcinoma (IDC) of the pancreas. METHODS Data from IDC patients who underwent radical surgery from 1990 to 2013 in our hospital were examined retrospectively. Incidence of intraductal spread of pancreatic cancer (IS), distance from the tumor edge, direction of IS and clinicopathological factors associated with the presence of IS were retrospectively examined with data from IDC patients who underwent radical surgery. RESULTS Among 260 IDC patients who underwent surgery, 184 eligible cases, IS was identified in 42 patients (22.8%) and mean length of IS was 18.7 ± 21.6 mm. Mean distances on the ampullary and distal sides of IS were 11.1 mm and 11.6 mm. IS was significantly more frequent in localized tumors (UICC T1-2 vs. 3-4, p = 0.007), with tumor diameter ≤2 cm (p = 0.034) and in cases with scarce microscopic perineural invasion (p = 0.047). Among patients who underwent pancreaticoduodenectomy and distal pancreatectomy, IS presence (11.6 vs. 21.8%), mean distance to the contralateral side (11.4 vs. 11.6 mm), and IS ≥ 2 cm (3.3 vs. 4.7%) showed no significant differences. Overall survival did not differ significantly between IS-positive and -negative patients in the full analysis set or propensity score-matched patients (42 matched pairs). CONCLUSIONS In setting resectional margins at 2 cm, a small proportion of cases (3.8%) showed positive surgical margins. Localized tumor (UICC: T1-2, or <2 cm in diameter) requires more care with surgical margins, warranting intraoperative frozen sections.

Meta-analysis of radical resection rates and margin assessment in pancreatic cancer. Br J Surg 2015; 102:1459-72. [PMID: 26350029 DOI: 10.1002/bjs.9892] [Citation(s) in RCA: 137] [Impact Index Per Article: 15.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2015] [Revised: 04/28/2015] [Accepted: 06/05/2015] [Indexed: 12/12/2022]
Abstract
BACKGROUND R0 resection rates (complete tumour removal with negative resection margins) in pancreatic cancer are 70-80 per cent when a 0-mm margin is used, declining to 15-24 per cent with a 1-mm margin. This review evaluated the R0 resection rates according to different margin definitions and techniques. METHODS Three databases (MEDLINE from 1946, PubMed from 1946 and Embase from 1949) were searched to mid-October 2014. The search terms included 'pancreatectomy OR pancreaticoduodenectomy' and 'margin'. A meta-analysis was performed with studies in three groups: group 1, axial slicing technique (minimum 1-mm margin); group 2, other slicing techniques (minimum 1-mm margin); and group 3, studies with minimum 0-mm margin. RESULTS The R0 rates were 29 (95 per cent c.i. 26 to 32) per cent in group 1 (8 studies; 882 patients) and 49 (47 to 52) per cent in group 2 (6 studies; 1568 patients). The combined R0 rate (groups 1 and 2) was 41 (40 to 43) per cent. The R0 rate in group 3 (7 studies; 1926 patients) with a 0-mm margin was 72 (70 to 74) per cent The survival hazard ratios (R1 resection/R0 resection) revealed a reduction in the risk of death of at least 22 per cent in group 1, 12 per cent in group 2 and 23 per cent in group 3 with an R0 compared with an R1 resection. Local recurrence occurred more frequently with an R1 resection in most studies. CONCLUSION Margin clearance definitions affect R0 resection rates in pancreatic cancer surgery. This review collates individual studies providing an estimate of achievable R0 rates, creating a benchmark for future trials.

Abstract
BACKGROUND Preoperative/neoadjuvant therapy (NT) is increasingly utilized for the treatment of pancreatic ductal adenocarcinoma (PDAC). However, little data exist regarding information on the use of additional postoperative therapy following NT. The lymph node ratio (LNR) is a prognostic marker of oncologic outcomes after NT and resection. In this study, we evaluated the effectiveness of postoperative therapy following NT, stratified by LNR. METHODS A prospective tumor registry database was queried to identify patients with PDAC who underwent resection following NT from 1990 to 2008. Clinicopathologic factors were compared to identify associations with overall survival (OS) and time to recurrence (TTR) based on postoperative chemotherapy status. RESULTS Thirty-six (14 %) of the 263 patients received additional postoperative therapy. No differences were observed in the pathologic characteristics between patients who received postoperative chemotherapy and those who did not. The median LNR was 0.12 for patients with N + disease. Following NT, the administration of postoperative therapy was associated with improved median OS (72 vs. 33 months; p = 0.008) for patients with an LNR < 0.15. There was no association between postoperative chemotherapy and OS for patients with LNR ≥ 0.15. Multivariate analysis demonstrated that the administration of postoperative systemic therapy in patients with a low LNR was associated with a reduced risk of death (hazard ratio 0.49; p = 0.02). CONCLUSION Postoperative chemotherapy after NT in patients with low LNR is associated with improved oncologic outcomes.

Abstract
Combined arterial resection during pancreatectomy can be a challenging treatment, and outcome would be more favorable if the tumor becomes technically removable from the artery. Neoadjuvant chemoradiotherapy (NACRT) is expected to achieve locoregional control and enable margin-negative resection. To investigate the effects of NACRT in patients with pancreatic adenocarcinoma (PDAC) which were deemed borderline resectable through preoperative imaging due to abutment of the major artery, including the superior mesenteric artery (SMA) or common hepatic artery (CHA), but were still considered to be technically removable. In the current study, comparisons were make between 71 patients who underwent upfront surgery and 21 patients who underwent NACRT followed by surgery in the strategy to preserve the artery, using unmatched and inverse probability of treatment weighting analysis (UMIN000017115). Fifty patients in the upfront surgery group and 18 in the NACRT group underwent curative resection (70% vs 86%, respectively; P = 0.16). The results of the propensity score weighted logistic regressions indicated that the incidences of pathological lymph node metastasis and a pathological positive resection margin were significantly lower in the NACRT group (odds ratio, 0.006; P < 0.001 and odds ratio, 0.007; P < 0.001, respectively). Among the propensity-score matched patients, the estimated 1- and 2-year survival rates in the upfront surgery group were 66.7% and 16.0%, respectively, and those in the NACRT group were 80.0% and 65.2%, respectively. In conclusion, it was suggested that chemoradiotherapy followed by surgery provided clinical benefits in patients with PDACs in contact with the SMA or CHA.

Radiological and surgical implications of neoadjuvant treatment with FOLFIRINOX for locally advanced and borderline resectable pancreatic cancer. Ann Surg 2015; 261:12-7.

Abstract
PURPOSE On the basis of the ACCORD trial, FOLFIRINOX is effective in metastatic pancreatic adenocarcinoma (PDAC), making it a rational choice for locally advanced PDAC (LA). Aims of this study are to evaluate the accuracy of imaging in determining the resectability of PDAC and to determine the surgical and clinicopathologic outcomes of pancreatic resections after neoadjuvant FOLFIRINOX therapy. PATIENTS AND METHODS Clinicopathologic data were retrospectively collected for surgical PDAC patients receiving neoadjuvant FOLFIRINOX or no neoadjuvant therapy between April 2011 and February 2014. Americas Hepato-Pancreato-Biliary Association/Society of Surgical Oncology/Society for Surgery of the Alimentary Tract consensus guidelines defined LA and borderline. Imaging was reviewed by a blinded senior pancreatic surgeon. RESULTS Of 188 patients undergoing resection for PDAC, 40 LA/borderline received FOLFIRINOX and 87 received no neoadjuvant therapy. FOLFIRINOX resulted in a significant decrease in tumor size, yet 19 patients were still classified as LA and 9 as borderline. Despite post-FOLFIRINOX imaging suggesting continued unresectability, 92% had an R0 resection. When compared with no neoadjuvant therapy, FOLFIRINOX resulted in significantly longer operative times (393 vs 300 minutes) and blood loss (600 vs 400 mL), but significantly lower operative morbidity (36% vs 63%) and no postoperative pancreatic fistulas. Length of stay (6 vs 7 days), readmissions (20% vs 30%), and mortality were equivalent (1% vs 0%). On final pathology, the FOLFIRINOX group had a significant decrease in lymph node positivity (35% vs 79%) and perineural invasion (72% vs 95%). Median follow-up was 11 months with a significant increase in overall survival with FOLFIRINOX. CONCLUSIONS After neoadjuvant FOLFIRINOX imaging no longer predicts unresectability. Traditional pathologic predictors of survival are improved, and morbidity is decreased in comparison to patients with clearly resectable cancers at the time of presentation.

Abstract
Pancreatic adenocarcinoma remains the fourth leading cause of cancer mortality in the U.S. Despite advances in surgical technique, radiotherapy technologies, and chemotherapeutics, the 5-year survival rate remains approximately 20% for the 15% of patients who are eligible for surgical resection. The majority of this group suffers metastatic recurrence. However, despite advances in therapies for patients with advanced pancreatic cancer, only surgery has consistently proven to improve long-term survival. Various combinations of chemotherapy, biologic-targeted therapy, and radiotherapy have been evaluated in different settings to improve outcomes. In this context, a neoadjuvant (preoperative) treatment strategy offers numerous potential benefits: (1) ensuring delivery of early, systemic therapy, (2) improving selection of patients for surgical therapy with truly localized disease, (3) potential downstaging of the neoplasm facilitating a negative margin resection in patients with locally advanced disease, and (4) providing a superior clinical trial mechanism capable of rapid assessment of the efficacy of novel therapeutics. This article reviews the recent trends in the management of pancreatic adenocarcinoma, with a particular emphasis on a multidisciplinary neoadjuvant approach to treatment.

Abstract
BACKGROUND AND PURPOSE Histopathological findings of patients who underwent resection for pancreatic adenocarcinoma (PC) after preoperative chemoradiotherapy (CRT) reportedly showed beneficial effects. The purpose of our study was to evaluate the correlation between histopathological effects (HE) of preoperative CRT and treatment parameters [radiation and gemcitabine (GEM) doses]. MATERIAL AND METHODS HE of CRT were assessed on 158 primary lesions of 157 patients with PC who underwent pancreatic resection after preoperative CRT with GEM between January 2006 and December 2011. The radiation dose delivered to the primary tumor site and surrounding regional nodal areas was 50 Gy until September 2009 followed by the dose escalation of a 10 Gy boost added for delivery with the field-in-field technique to the roots of the celiac and superior mesenteric arteries. Intravenous administration of GEM (1000 /m(2)) was initiated concurrently on days 1, 8, and 15, every 4 weeks and generally repeated for 3 cycles. HE of CRT on the primary tumor were categorized based on the number of tumor cells destroyed. RESULTS The median overall survival time was 74.5 months and 3-year and 5-year survival rates were 64.3% and 54.5%, respectively. Dose-volume parameters of radiation such as D33 with a cut-off value of 51.6 Gy were correlated significantly with HE (p=.0230). Lesions having received GEM>7625 mg/m(2) before surgical resection more frequently showed positive HE (p=.0002). Multivariate logistic regression analysis demonstrated that both D33 and cumulative GEM dose were significant predictors of definite HE (p=.0110 and <.0001, respectively). CONCLUSIONS Our retrospective analysis showed that dose intensity of radiation and GEM is significantly related to HE of preoperative CRT for PC.

Abstract
Treatment of pancreatic cancer is increasingly multimodal, with patients receiving chemotherapy, radiation, and surgical extirpation in hope of long-term cure. There is ongoing debate over the timing, sequence, and necessity of these treatments as they pertain to the spectrum of local-regional disease. Current guidelines support a neoadjuvant strategy in patients with locally advanced and borderline resectable disease. Although there is currently no high-level evidence to recommend neoadjuvant therapy for all patients, there are data to suggest that wider application of neoadjuvant therapy may be beneficial. Random-assignment prospective trials are ongoing. In this review we examine the literature addressing a neoadjuvant approach to potentially resectable, borderline resectable, and locally advanced pancreatic cancer and highlight the outcomes of preoperative emergence of latent metastatic disease, attempted resection rates, margin negative resection rates, and pathologic response to treatment.

Abstract
BACKGROUND Most survival studies comparing non-radical resections to bypass surgery in patients with pancreatic cancer often do not differentiate between an R1 and R2 resection. The aim of this study was to evaluate whether non-radical R1 and R2 resections have better postoperative outcomes and survival compared to a palliative bypass. METHODS A single center cohort study was performed analyzing mortality, morbidity and 1-year survival after R1 (tumor cells within 1 mm from the circumferential margin), R2 and bypass surgery in patients with pancreatic cancer. For the systematic review, studies were identified comparing R1 or R2 resections with bypass, in patients with pancreatic cancer. Postoperative outcomes were compared including the cohort study. RESULTS The cohort study (n=405) showed higher morbidity rates after R1 (n=191) and R2 (n=11) resections compared to bypass (52% and 73% vs. 34%, p < 0.01). In-hospital mortality did not differ (overall 1.7%). 1-year survival rates were 71%, 46% and 32% after R1, R2 resection and bypass (p=0.6 between R2 and bypass). The systematic review identified 8 studies, after including the cohort study 1535 patients were analyzed. Increased morbidity after R1-R2 resection (48%) compared to bypass (30-34%) was found. Median survival was 14-18 months after R1 resection vs. 9-13 months after bypass and 8.5-11.5 months after R2 resection vs. 7.5-10.7 months after bypass. CONCLUSION An R2 resection should be avoided in patients with pancreatic cancer due to its poor prognosis. Survival benefit after an R1 resection, as compared to bypass surgery, justifies a resection despite the increased morbidity rate.

Abstract
Pancreatic ductal adenocarcinoma is a highly lethal cancer that is rarely curable at the time of presentation. Unfortunately, most patients are diagnosed with either metastatic or locally advanced disease, which is not amenable to surgery owing to the high likelihood of incomplete resection. Given the generally poor prognosis with propensity for metastatic failure greater than that for local failure, treatment options are variable, and include chemotherapy, radiotherapy, targeted therapies, and combinations thereof. This review summarizes the current evidence for definitive management of locally advanced pancreatic adenocarcinoma, as well as the role of palliative therapies. Future directions, including the development of predictive biomarkers and novel systemic agents, are also discussed.

Abstract
OBJECTIVE We report the response to pre-operative gemcitabine-based chemoradiotherapy for pancreatic adenocarcinoma. METHODS Thirty-five consecutive patients with borderline resectable pancreatic adenocarcinoma of UICC Stage II or III with portal vein invasion or tumor abutment of artery received radiotherapy (twice daily fractions of 1.5 Gy, 5 days/week, total dose: 36 Gy; 30 Gy for Phase I Level 1) with weekly intravenous infusions of gemcitabine (400, 600 and 800 mg/m(2)) at Days 1 and 8 for Phase I and 800 mg/m(2) for Phase II. Restaging was repeated after completion of chemoradiotherapy. RESULTS Twenty-six of the 35 (74.3%) patients underwent resection. The dose-limiting toxicities were Grade 4 neutropenia and thrombocytopenia. The recommended regimen was total radiation dose of 36 Gy with gemcitabine 800 mg/m(2). Surgical resection was conducted in 11 of the 15 (73.3%) patients in Phase I study and 15 of the 20 (75.0%) in Phase II. After recommended dose chemoradiotherapy and surgical resection, the median disease-free survival was 17.4 months (5-year survival rate = 14.3%). The median overall survival time and 5-year survival rate were 41.2 months and 28.6%, respectively, for the 21 patients who underwent resection and 10.0 months and 0%, respectively, for those 5 who did not (P = 0.004). CONCLUSION Our pre-operative gemcitabine-based chemoradiotherapy was well tolerated and safe.

Abstract
Electrochemotherapy is an effective treatment for various cutaneous tumors and could be translated into treatment of deep-seated tumors. With this aim, a prospective clinical phase I/II study was conducted to evaluate the feasibility and safety of intraoperative Electrochemotherapy (ECT) in locally advanced pancreatic adenocarcinoma: the preliminary results are reported in this study. The secondary endpoint was to assess treatment response in terms of morphological and functional criteria based on Magnetic Resonance Imaging. Eleven consecutive patients were enrolled in a clinical phase I/II study approved by the Ethics Committee of the National Cancer Institute G. Pascale Foundation - IRCCS of Naples. Electrochemotherapy with bleomycin was performed during open surgery. All patients underwent MR and CT scan, before and after ECT treatment, using morphological and functional imaging. RECIST criteria were used to evaluate ECT response on CT and MR images. Functional parameters were also used to evaluate ECT response on MR images. No acute (intraoperative) and/or postoperative serious adverse events related to electrochemotherapy were observed; no clinically significant electrocardiographic, hemodynamic, or serum biologic changes were noted. No clinically relevant elevation of amylase or lipase levels was observed and no bleeding or damage to surrounding viscera occurred. Electrochemotherapy of locally advanced pancreatic adenocarcinoma proved to be a feasible and safe treatment modality. Dynamic and diffusion MR imaging is more suitable to assess ECT treatment response than CT imaging and morphological MR alone, after one month of treatment.

Abstract
BACKGROUND The role for neoadjuvant systemic therapy in resectable pancreas adenocarcinoma remains undefined. OBJECTIVE We evaluated the efficacy of gemcitabine and oxaliplatin administered as preoperative therapy in patients with resectable pancreas adenocarcinoma. METHODS Eligible patients were screened using computed tomography-pancreas angiography, laparoscopy, endoscopic ultrasonography, and fine-needle aspiration cytology to identify 38 patients who received 4 cycles of neoadjuvant gemcitabine 1000 mg/m intravenously over 100 minutes and oxaliplatin 80 mg/m intravenously over 2 hours, every 2 weeks. Patients whose tumors remained resectable at restaging proceeded to operation and subsequently received 5 cycles of adjuvant gemcitabine (1000 mg/m intravenously over 30 minutes days 1, 8, and 15 every 4 weeks). The primary endpoint was 18-month overall survival and secondary endpoints included radiological, tumor marker and pathological response to neoadjuvant therapy, time to recurrence, patterns of failure, and feasibility of obtaining preoperative core biopsies. RESULTS Thirty-five of 38 patients (92%) completed neoadjuvant therapy. Twenty-seven patients underwent tumor resection (resectability rate 71%), of which 26 initiated adjuvant therapy for a total of 23 patients (60.5%) who completed all planned therapy. The 18-month survival was 63% (24 patients alive). The median overall survival for all 38 patients was 27.2 months (95% confidence interval: 17-NA) and the median disease-specific survival was 30.6 months (95% confidence interval: 19-NA). CONCLUSIONS This study met its endpoint and provided a signal suggesting that exploration of neoadjuvant systemic therapy is worthy of further investigation in resectable pancreas adenocarcinoma. Improved patient selection and more active systemic regimens are key. Clinical trials identification: NCT00536874.

Abstract
BACKGROUND To asses the impact of CA 19-9 and weight loss/gain on outcome after neoadjuvant chemoradiation (CRT) in patients with locally advanced pancreatic cancer (LAPC). METHODS We analyzed 289 patients with LAPC treated with CRT for LAPC. All patients received concomitant chemotherapy parallel to radiotherapy and adjuvant treatments. CA 19-9 and body weight were collected as prognostic and predictive markers. All patients were included into a regular follow-up with reassessment of resectability. RESULTS Median overall survival in all patients was 14 months. Actuarial overall survival was 37 % at 12 months, 12 % at 24 months, and 4 % at 36 months. Secondary resectability was achieved in 35 % of the patients. R0/R1 resection was significantly associated with increase in overall survival (p = 0.04). Intraoperative radiotherapy was applied in 50 patients, but it did not influence overall survival (p = 0.05). Pretreatment CA 19-9 significantly influenced overall survival using different cutoff values. With increase in CA 19-9 levels, the possibility of secondary surgical resection decreased from 46 % in patients with CA 19-9 levels below 90 U/ml to 31 % in the group with CA 19-9 levels higher than 269 U/ml. DISCUSSION This large group of patients with LAPC treated with neoadjuvant CRT confirms that CA 19-9 and body weight are strong predictive and prognostic factors of outcome. In the future, individual patient factors should be taken into account to tailor treatment.

BMC Cancer 2014; 14:411.

Abstract
BACKGROUND Median OS after surgery in curative intent for non-metastasized pancreas cancer ranges under study conditions from 17.9 months to 23.6 months. Tumor recurrence occurs locally, at distant sites (liver, peritoneum, lungs), or both. Observational and autopsy series report local recurrence rates of up to 87% even after potentially "curative" R0 resection. To achieve better local control, neoadjuvant CRT has been suggested for preoperative tumour downsizing, to elevate the likelihood of curative, margin-negative R0 resection and to increase the OS rate. However, controlled, randomized trials addressing the impact of neoadjuvant CRT survival do not exist. METHODS/DESIGN The underlying hypothesis of this randomized, two-armed, open-label, multicenter, phase III trial is that neoadjuvant CRT increases the three-year overall survival by 12% compared to patients undergoing upfront surgery for resectable pancreatic cancer. A rigorous, standardized technique of histopathologically handling Whipple specimens will be applied at all participating centers. Overall, 410 patients (n=205 in each study arm) will be enrolled in the trial, taking into regard an expected drop out rate of 7% and allocated either to receive neoadjuvant CRT prior to surgery or to undergo surgery alone. Circumferential resection margin status, i.e. R0 and R1 rates, respectively, surgical resectability rate, local and distant disease-free and global survival, and first site of tumor recurrence constitute further essential endpoints of the trial. DISCUSSION For the first time, the NEOPA study investigates the impact of neoadjuvant CRT on survival of resectable pancreas head cancer in a prospectively randomized manner. The results of the study have the potential to change substantially the treatment regimen of pancreas cancer. TRIAL REGISTRATION Clinical Trial gov: NCT01900327, DRKS00003893, ISRCTN82191749.

Abstract
Many patients with pancreas cancer present with locally advanced pancreatic cancer (LAPC). The principle tools used for diagnosis and staging of LAPC include endoscopic ultrasound, axial imaging with computed tomography and magnetic resonance imaging, and diagnostic laparoscopy. The definition of resectability has historically been vague, as there is considerable debate and controversy as to the definition of LAPC. For the patient with LAPC, there is some level of involvement of the surrounding vascular structures, which include the superior mesenteric artery, celiac axis, hepatic artery, superior mesenteric vein, or portal vein. When feasible, most surgeons would recommend possible surgical resection for patients with borderline LAPC, with the goal of an R0 resection. For initially unresectable LAPC, neoadjuvant should be strongly considered. Specifically, these patients should be offered neoadjuvant therapy, and the tumor should be assessed for possible response and eventual resection. The efficacy of neoadjuvant therapy with this approach as a bridge to potential curative resection is broad, ranging from 3%-79%. The different modalities of neoadjuvant therapy include single or multi-agent chemotherapy combined with radiation, chemotherapy alone, and chemotherapy followed by chemotherapy with radiation. This review focuses on patients with LAPC and addresses recent advances and controversies in the field.
