Abstract
Importance National guidelines endorse treatment with neoadjuvant therapy for borderline resectable pancreatic ductal adenocarcinoma (PDAC), but the optimal strategy remains unclear. Objective To compare treatment with neoadjuvant modified FOLFIRINOX (mFOLFIRINOX) with or without hypofractionated radiation therapy with historical data and establish standards for therapy in borderline resectable PDAC. Design, Setting, and Participants This prospective, multicenter, randomized phase 2 clinical trial conducted from February 2017 to January 2019 among member institutions of National Clinical Trials Network cooperative groups used standardized quality control measures and included 126 patients, of whom 70 (55.6%) were registered to arm 1 (systemic therapy; 54 randomized, 16 following closure of arm 2 at interim analysis) and 56 (44.4%) to arm 2 (systemic therapy and sequential hypofractionated radiotherapy; all randomized before closure). Data were analyzed by the Alliance Statistics and Data Management Center during September 2021. Interventions Arm 1: 8 treatment cycles of mFOLFIRINOX (oxaliplatin, 85 mg/m2; irinotecan, 180 mg/m2; leucovorin, 400 mg/m2; and infusional fluorouracil, 2400 mg/m2) over 46 hours, administered every 2 weeks. Arm 2: 7 treatment cycles of mFOLFIRINOX followed by stereotactic body radiotherapy (33-40 Gy in 5 fractions) or hypofractionated image-guided radiotherapy (25 Gy in 5 fractions). Patients without disease progression underwent pancreatectomy, which was followed by 4 cycles of treatment with postoperative FOLFOX6 (oxaliplatin, 85 mg/m2; leucovorin, 400 mg/m2; bolus fluorouracil, 400 mg/m2; and infusional fluorouracil, 2400 mg/m2 over 46 hours). Main Outcomes and Measures Each treatment arm's 18-month overall survival (OS) rate was compared with a historical control rate of 50%. A planned interim analysis mandated closure of either arm for which 11 or fewer of the first 30 accrued patients underwent margin-negative (R0) resection. Results Of 126 patients, 62 (49%) were women, and the median (range) age was 64 (37-83) years. Among the first 30 evaluable patients enrolled to each arm, 17 patients in arm 1 (57%) and 10 patients in arm 2 (33%) had undergone R0 resection, leading to closure of arm 2 but continuation to full enrollment in arm 1. The 18-month OS rate of evaluable patients was 66.7% (95% CI, 56.1%-79.4%) in arm 1 and 47.3% (95% CI 35.8%-62.5%) in arm 2. The median OS of evaluable patients in arm 1 and arm 2 was 29.8 (95% CI, 21.1-36.6) months and 17.1 (95% CI, 12.8-24.4) months, respectively. Conclusions and Relevance This randomized clinical trial found that treatment with neoadjuvant mFOLFIRINOX alone was associated with favorable OS in patients with borderline resectable PDAC compared with mFOLFIRINOX treatment plus hypofractionated radiotherapy; thus, mFOLFIRINOX represents a reference regimen in this setting. Trial Registration ClinicalTrials.gov Identifier: NCT02839343.

Abstract
Borderline resectable (BR) pancreatic ductal adenocarcinoma (PDAC) is currently a well-recognized entity, characterized by some specific anatomic, biological and conditional features: It includes patients with a stage of disease intermediate between the resectable and the locally advanced ones. The term BR identifies a tumour with an aggressive biological behaviour, on which a neoadjuvant approach instead of an upfront surgery one should be preferred, in order to obtain a radical resection (R0) and to avoid an early recurrence after surgery. Even if during the last decades several studies on this topic have been published, some aspects of BR-PDAC still represent a matter of debate. The aim of this review is to critically analyse the available literature on this topic, particularly focusing on: The problem of the heterogeneity of definition of BR-PDAC adopted, leading to a misinterpretation of published data; its current management (neoadjuvant vs upfront surgery); which neoadjuvant regimen should be preferably adopted; the problem of radiological restaging and the determination of resectability after neoadjuvant therapy; the post-operative outcomes after surgery; and the role and efficacy of adjuvant treatment for resected patients that already underwent neoadjuvant therapy.

Abstract
Patients with unresectable pancreatic ductal adenocarcinoma (UR-PDAC) are traditionally treated with palliative chemotherapy. The aim of this study was to evaluate the safety and efficacy of conversion surgery for initially UR-PDAC following induction therapy. The PubMed and Embase databases were systematically searched for eligible studies published between January 2000 and October 2020. Thirty-two series involving 1270 patients with 1056 locally advanced (LA) disease and 214 distant metastases were reviewed. The median mortality and morbidity was 0% (range 0-10%) and 47.1% (range 8.6-93.3%), respectively. Lymph-node negativity, negative resection margin and pathological complete response were observed in a median of 62.9% (38.5-90.9%), 84.4% (32.8-100%) and 6.7% (0-45.8%) of the specimens. The median survival was 32 (16.4-63.9) months with a 3-year survival rate of 47% (22-80%). Meta-analysis demonstrated that conversion surgery of initially UR-PDAC was associated with a significantly improved survival (hazard ratio [HR] = 0.55; 95% confidence intervals (CI) 0.45-0.66, P < 0.001). There was no significant difference in survival between the group with LA disease and that with distant metastases after conversion surgery (HR = 0.96; 95% CI 0.72-1.28, P = 0.790). Conversion surgery improved long-term survival of patients with initially UR-PDAC who had favorable response to induction therapy.

Pancreatology 2020; 20:247-253.

Abstract
BACKGROUND Although several studies have focused on the oncologic impact of the preoperative prognostic nutritional index (PNI), there is no study correlating the preoperative PNI changes with the oncologic outcome of resected pancreatic cancer following neoadjuvant chemotherapy (NAC). METHODS We retrospectively analyzed 107 pancreatic ductal adenocarcinoma patients who underwent NAC followed by surgical resection. ΔPNI was defined as post-NAC PNI subtracted from pre-NAC PNI. Patients were divided into high (≥-1.94, n = 54) and low ΔPNI groups (<-1.94, n = 53). Long-term oncologic outcomes, such as overall survival (OS) and disease-free survival (DFS), were compared. Univariate and multivariate analysis were used to identify independent prognostic factors. RESULTS The high ΔPNI group correlated with lower pre-NAC PNI (46.96 ± 4.68 vs. 51.77 ± 5.63, p < 0.001) and higher post-NAC PNI (50.05 ± 4.80 vs. 42.56 ± 7.44, p < 0.001) more than the low ΔPNI group. The high ΔPNI group was also associated with longer OS compared with the low ΔPNI group (mean OS: 63.97 months [95% CI: 49.95-77.99] vs. 41.16 months [95% CI: 27.66-54.66], p = 0.003); there was no significant difference in DFS (p > 0.05). Multivariate analysis revealed that low ΔPNI was an independent risk factor for OS (HR, 3.516; 95% CI, 1.885-6.558; p < 0.001), but not for DFS (p > 0.05). CONCLUSIONS Low ΔPNI (<-1.94) was an independent risk factor for the overall survival of resected pancreatic cancer patients following NAC. In the preoperative setting, improving the PNI can better the long-term oncologic outcome of this condition.

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
Background We sought to examine the impact of neoadjuvant chemotherapy (NCT), single agent or multiagent chemotherapy, and neoadjuvant chemoradiation (NCRT) on survival in pancreatic cancer. Methods Utilizing the National Cancer Database, we identified patients who underwent pancreatic resection for adenocarcinoma (2006 to 2013). Overall survival (OS) analysis was performed using the Kaplan-Meier method. Multivariable cox proportional hazard models (MVA) and propensity score matching (PSM) were developed to identify predictors of survival. For upfront surgery (UFS), OS was limited to receipt of adjuvant treatment. Results We identified 26,563 patients who underwent pancreatic resection: UFS =23,877, NCRT =1,482, and NCT =1,204. Multiagent chemotherapy was utilized in 77% of NCT and 42% of NCRT. There was improved R0 resections associated with neoadjuvant therapy compared to UFS, however, there was no difference between NCT and NCRT. In addition, the was improved R0 with MA-NCT (P<0.001) but not for single agent NCT (P=0.26). After PSM, the median OS for UFS, SA-NCT, MA-NCT, SA-NCRT, and MA-NCRT was 21.9, 21.5, 29.8, 25.3, and 25.8 months in all patients (P=0.001), and 23.6, 23.9, 31.6, 25.9, and 26.6 months in R0 patients (P=0.03), respectively. There was no difference in OS in patients with R1/2 resection. MVA after PSM demonstrated that only MA-NCT was associated with decreased mortality while increasing age, higher Charlson-Deyo index, N1, higher grade, tumor size, and positive margins were associated with higher mortality. Conclusions There was improved OS associated with MA-NCT in pancreatic cancer patients compared to UFS with adjuvant therapy.

Abstract
Background Neoadjuvant therapy has emerged as an alternative treatment strategy for potentially resectable pancreatic cancer. In the absence of large randomized controlled trials offering a direct comparison, this study aims to use Markov decision analysis to compare efficacy of traditional surgery first (SF) and neoadjuvant treatment (NAT) pathways for potentially resectable pancreatic cancer. Methods An advanced Markov decision analysis model was constructed to compare SF and NAT pathways for potentially resectable pancreatic cancer. Transition probabilities were calculated from randomized control and Phase II/III trials after comprehensive literature search. Utility outcomes were measured in overall and quality-adjusted life months (QALMs) on an intention-to-treat basis as the primary outcome. Markov cohort analysis of treatment received was the secondary outcome. Model uncertainties were tested with one and two-way deterministic and probabilistic Monte Carlo sensitivity analysis. Results SF gave 23.72 months (18.51 QALMs) versus 20.22 months (16.26 QALMs). Markov Cohort Analysis showed that where all treatment modalities were received NAT gave 35.05 months (29.87 QALMs) versus 30.96 months (24.86QALMs) for R0 resection and 34.08 months (29.87 QALMs) versus 25.85 months (20.72 QALMs) for R1 resection. One-way deterministic sensitivity analysis showed that NAT was superior if the resection rate was greater than 51.04% or below 75.68% in SF pathway. Two-way sensitivity analysis showed that pathway superiority depended on obtaining multimodal treatment in either pathway. Conclusion Whilst NAT is a viable alternative to traditional SF approach, superior pathway selection depends on the individual patient’s likelihood of receiving multimodal treatment in either pathway.

Abstract
The purpose of this review was to assess whether neoadjuvant chemotherapy and chemoradiotherapy (CRT) result in differential postoperative morbidity and mortality as compared with pancreatic tumor resection surgery alone. Using PRISMA guidelines and the PubMed search engine, we reviewed all prospective phase II trials of neoadjuvant chemotherapy and CRT for pancreatic cancer that examined postoperative morbidities and mortalities. A total of 30 articles were identified, collated, and analyzed. Risks of postoperative complications vary based on trial. With surgery alone, the most common postoperative complications included delayed gastric emptying (DGE) (17% to 24%), pancreatic fistula (10% to 20%), anastomotic leaks (0% to 15%), postoperative bleeding (2% to 13%), and infections/sepsis (17% to 20%). With surgery alone, the mortality was <5%. Neoadjuvant chemotherapy showed comparable fistula rates (3% to 4%), leaks (3% to 11%), infection (3% to 7%), with mortality 0% to 4% in all but 1 study. CRT for resectable/borderline resectable patients also showed comparable complication rates: DGE (6% to 15%), fistulas (2% to 3%), leaks (3% to 7%), bleeding/hemorrhage (2% to 13%), infections/sepsis (3% to 19%), with 9/13 studies showing a mortality of ≤4%. As compared with initially borderline/resectable tumors, CRT for initially unresectable tumors (despite less data) showed higher complication rates: DGE (13% to 33%), fistulas (3% to 25%), infections/sepsis (3% to 16%). However, the confounding factor of the potentially higher tumor burden as an associative agent remains. The only parameters slightly higher than historical surgery-only complication rates were leaks and bleeding/hemorrhage (13% to 20%). Mortality rates in these patients were consistently 0%, with 2 outliers. Hence, neoadjuvant chemotherapy/CRT is safe from a postoperative complication standpoint, without significant increases in complication rates compared with surgery alone. Resectable and borderline resectable patients have fewer complications as compared with unresectable patients, although data for the latter are lacking.

Abstract
Pancreatic cancer is the fourth leading cause of cancer mortality and is associated with a poor overall survival even when diagnosed early and considered resectable. Complete surgical removal with negative histological margins is an independent predictor of survival and remains the only potential curative treatment. In borderline resectable pancreatic adenocarcinoma (BRPAC), preoperative systemic therapy may increase resectability and margin-negative resection rate. There is no current consensus on the optimal chemotherapy regimen for BRPAC. The present case describes a patient with BRPAC who achieved a pathological complete response to neoadjuvant FOLFIRINOX (folinic acid, fluorouracil, irinotecan and oxaliplatin), but early relapse following a pancreaticoduodenectomy without vascular resection, with an uneventful postoperative course, except for a pulmonary embolism.

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.

Abstract
Background Pancreatic cancer is the fourth largest cause of cancer death in the United States and Europe with over 100,000 deaths per year in Europe alone. The overall 5-year survival ranges from 2–7 % and has hardly improved over the last two decades. Approximately 15 % of all patients have resectable disease at diagnosis, and of those, only a subgroup has a resectable tumour at surgical exploration. Data from cohort studies have suggested that outcome can be improved by preoperative radiochemotherapy, but data from well-designed randomized studies are lacking. Our PREOPANC phase III trial aims to test the hypothesis that median overall survival of patients with resectable or borderline resectable pancreatic cancer can be improved with preoperative radiochemotherapy. Methods/design The PREOPANC trial is a randomized, controlled, multicentric superiority trial, initiated by the Dutch Pancreatic Cancer Group. Patients with (borderline) resectable pancreatic cancer are randomized to A: direct explorative laparotomy or B: after negative diagnostic laparoscopy, preoperative radiochemotherapy, followed by explorative laparotomy. A hypofractionated radiation scheme of 15 fractions of 2.4 gray (Gy) is combined with a course of gemcitabine, 1,000 mg/m2/dose on days 1, 8 and 15, preceded and followed by a modified course of gemcitabine. The target volumes of radiation are delineated on a 4D CT scan, where at least 95 % of the prescribed dose of 36 Gy in 15 fractions should cover 98 % of the planning target volume. Standard adjuvant chemotherapy is administered in both treatment arms after resection (six cycles in arm A and four in arm B). In total, 244 patients will be randomized in 17 hospitals in the Netherlands. The primary endpoint is overall survival by intention to treat. Secondary endpoints are (R0) resection rate, disease-free survival, time to locoregional recurrence or distant metastases and perioperative complications. Secondary endpoints for the experimental arm are toxicity and radiologic and pathologic response. Discussion The PREOPANC trial is designed to investigate whether preoperative radiochemotherapy improves overall survival by means of increased (R0) resection rates in patients with resectable or borderline resectable pancreatic cancer.

Pancreatectomy with major arterial resection after neoadjuvant chemoradiotherapy gemcitabine and S-1 and concurrent radiotherapy for locally advanced unresectable pancreatic cancer. Surgery 2015; 158:191-200. [PMID: 25900035 DOI: 10.1016/j.surg.2015.02.016] [Citation(s) in RCA: 37] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/04/2014] [Revised: 02/07/2015] [Accepted: 02/19/2015] [Indexed: 12/20/2022]
Abstract
BACKGROUND Pancreatic cancer (PC) with arterial invasion is currently a contraindication to resection and has a miserable prognosis. METHODS Seventeen patients with locally advanced PC involving the celiac axis and/or common hepatic artery (CHA) who received chemoradiotherapy (CRT) composed of gemcitabine, S-1, and external beam irradiation over the last 2 years were investigated. Thirteen patients underwent pancreatectomy with major arterial resection: 6 distal pancreatectomies with resection of the celiac axis, 4 total pancreatectomies with resection of both the celiac axis and the CHA, and 3 pancreatoduodenectomies with resection of the CHA. Preoperative arterial embolization and/or arterial reconstruction to prevent ischemic gastropathy and hepatopathy was performed in 7 of the 13 patients. RESULTS Distant metastases were found in 3 patients after CRT. One patient did not consent to operation after CRT. The morbidity rate of the 13 patients who underwent surgery was 62% (8/13), but no deaths occurred. Although there were no responders on CT, >90% of tumor cells were necrotic on histopathology in 5 of 13 tumors after CRT. Invasion of the celiac axis remained in 5 tumors, and extrapancreatic plexus invasion remained in 8 tumors, but an R0 resection was achieved in 12 of 13 tumors. Lymph node metastases were found in 3 of 13 cases. The overall 1-year survival rate from commencement of CRT and resection was 12 of 13 patients. CONCLUSION Neoadjuvant CRT containing gemcitabine and S-1 and subsequent pancreatectomy with major arterial resection for patients with locally advanced PC with arterial invasion were carried out safely with an acceptable R0 resection acceptable morbidity and mortality, and encouraging survival (12 of 13) at 1 year postoperatively.

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
Pancreatic adenocarcinoma (PCA) is associated with high rates of cancer-related morbidity and mortality. Yet despite modern treatment advances, the only curative therapy remains surgical resection. The adjuvant therapeutic standard of care for PCA in the United States includes both chemotherapy and chemoradiation; however, an optimal regimen has not been established. For patients with resectable and borderline resectable PCA, recent investigation has focused efforts on evaluating the feasibility and efficacy of neoadjuvant therapy. Neoadjuvant therapy allows for early initiation of systemic therapy and identification of patients who harbor micrometastatic disease, thus sparing patients the potential morbidities associated with unnecessary radiation or surgery. This article critically reviews the data supporting or refuting the role of radiation therapy in the neoadjuvant and adjuvant settings of PCA management, with a particular focus on determining which patients may be more likely to benefit from radiation therapy.

Abstract
Pancreatic adenocarcinoma remains a most deadly malignancy, with an overall 5-year survival of 5%. A subset of patients will be diagnosed with potentially resectable disease, and while complete surgical resection provides the only chance at cure, data from trials of postoperative chemoradiation and/or chemotherapy demonstrate a modest survival advantage over those patients who undergo resection alone. As such, most practitioners believe that completion of multimodality therapy is the optimal treatment. However, the sequence of surgery, chemotherapy and radiation therapy is frequently debated, as patients may benefit from a neoadjuvant approach by initiating chemotherapy and/or chemoradiation prior to resection. Here we review the rationale for neoadjuvant therapy, which includes a higher rate of completion of multimodality therapy, minimizing the risk of unnecessary surgical resection for patients who develop early metastatic disease, improved surgical outcomes and the potential for longer overall survival. However, there are no prospective, randomized studies of the neoadjuvant approach compared to a surgery-first strategy; the established and ongoing investigations of neoadjuvant therapy for pancreatic cancer are discussed in detail. Lastly, as the future of therapeutic regimens is likely to entail patient-specific genetic and molecular analyses, and the treatment that is best applied based on those data, a review of clinically relevant biomarkers in pancreatic cancer is also presented.

Abstract
BACKGROUND Approximately 20 % of patients affected by pancreatic ductal adenocarcinoma are amenable to surgical resection. Several tumours are reported as "borderline resectable" because of their proximity to the major vessels. In the effort to achieve a radical tumour removal, vein resection has been proposed, but its oncological benefits remain debated. METHODS Our aim is to investigate morbidity, mortality and survival after pancreatectomy with vein resection. RESULTS Forty patients underwent pancreatectomy and vein resection (group A), and 20 patients (group B) underwent bilio-enteric and/or gastro-entero bypass. In group A, cancer vein invasion was microscopically proven in 14 cases (35 %). Vein infiltration, tumour differentiation and node-positive disease were not adverse prognostic variables. No difference in survival was seen over a 1-year follow-up. After this period, group A showed significant survival benefits with a longer stabilisation of the disease (p = 0.005). Tumour-free resection margins and adjuvant chemoradiotherapy were the most important prognostic factors (p < 0.05). CONCLUSIONS Suspicion of vein infiltration should not be a contraindication to resection. Pancreatectomy can be safely performed with an acceptable morbidity and better survival trend.

Abstract
OBJECTIVE Controversy remains existed whether chemoradiotherapy (CRT), especially neoadjuvant chemoradiotherapy (neoadjuvant CRT) achieves a significant benefit in resectable pancreatic cancer (PC) treatment. In this meta-analysis, we aimed to clarify the benefits of CRT and neoadjuvant CRT in resectable PC. METHODS Eligible trials were identified from MEDLINE, EMBASE, Cochrane center, China National Knowledge Internet and Wanfang database since their inception to July 31, 2013. Only patients with resectable PC, who underwent tumor resection and received CRT and/or neoadjuvant CRT, were enrolled. The treatment outcomes were overall survival (OS) and progression-free survival (PFS). Hazard ratio (HR) with a 95% confidence interval (CI) was used to measure the pooled effect according to a fixed-effects model. The statistical heterogeneity between trials was detected by χ(2) and I (2) test. Sensitivity analyses were also carried out. RESULTS A total of 28 studies were identified as relevant, but only 17 studies with a total of 3,088 patients were included in the comparison between CRT versus non-CRT, and a total number of three studies with 189 patients included in the comparison between neoadjuvant CRT versus postoperative CRT. The comparison between CRT and non-CRT showed that the overall pooled HR for death was 0.96 (95% CI 0.89-1.03; P = 0.28). The HR for progress was 0.83 (95% CI 0.68-1.03, P = 0.09). Comparison between neoadjuvant CRT and adjuvant CRT revealed a pooled HR of 0.93 (95% CI 0.69-1.25; P = 0.62). CONCLUSIONS This meta-analysis showed that CRT showed no significant effect on OS and PFS when compared to non-CRT. Neoadjuvant CRT showed no significant effect over postoperative adjuvant CRT.

Abstract
Chemotherapy is proven to play a central role in the adjuvant management of pancreatic cancer. A number of studies have validated its small but significant survival benefit to patients following surgical resection, but many questions about the optimal adjuvant chemotherapeutic management of pancreatic cancer still persist. Currently, the benefits of both the chemotherapeutic agents gemcitabine and 5-fluorouracil have been validated as adjuvant options, with a preference for gemcitabine emerging based on its greater tolerability. Methods to individualize the selection of an adjuvant agent based on an individual tumor's characteristics are being explored, and additional novel agents and regimens are actively being investigated. In the studies that established chemotherapy's adjuvant benefit, a controversy simultaneously developed as to the role of the concurrent use of adjuvant radiation therapy in addition to chemotherapy, leading to the development of a conflicting consensus on how to adjuvantly manage pancreatic cancer patients. Chemotherapy given concurrently with radiation therapy has emerged as the preferred adjuvant approach in the United States, whereas chemotherapy alone is preferred in Europe. In addition to the debate over modality, a separate debate of treatment timing has emerged from studies of neoadjuvant therapy, which has demonstrated a survival benefit in the management of pancreatic cancer, but has not been directly compared with postsurgical adjuvant therapy. This review discusses the evidence for chemotherapy in the adjuvant management of pancreatic cancer, including both the choice of agent and value of concurrent radiation therapy, as well as future directions with novel agents and regimens, techniques of response prediction, and timing to postsurgical adjuvant versus neoadjuvant therapy.

Abstract
Pancreatic cancer has a poor prognosis after complete macroscopic resection combined with chemotherapy. Even after neoadjuvant chemotherapy, R0 resection is often not possible. Moreover, current imaging techniques cannot reliably distinguish viable cancer cells from scar tissue at the resectional margin. We investigated the use of a conditionally replicative adenovirus (CRAd), Ad5/3Cox2CRAd-ΔE3ADP-Luc, for imaging the effects of chemotherapy. The CRAd infectivity of pancreatic cancer cells was enhanced by a chimeric Ad5/3 fiber, E1A expression was under the control of the Cox2 promoter, and the luciferase gene was inserted adjacent to the adenovirus death protein (ADP) gene. Subcutaneous xenografts of the pancreatic cancer cell line MiaPaCa-2 were established in 24 BALB/c nu/nu mice. When xenografts reached a diameter of 4-6 mm (day 1), the mice were injected i.p. with either PBS (group A; n = 12) or 1000 mg/kg gemcitabine (group B; n = 12), weekly. On days 19, 26, 33, and 40, CRAd were injected intratumorally into three mice in groups A and B. Bioluminescence was imaged 72 h after CRAd injection, and gross tumor volumes were measured then tumors were removed for ex vivo histopathology using H&E and Ki-67 staining. Correlations between gross tumor volume, pathological evaluation of the percentage of viable tumor area, and CRAd bioluminescence were analyzed. Bioluminescence correlated closely with the percentage of viable tumor area (R = 0.96), but not with gross tumor volume (R = 0.31). Therefore, CRAds might be reliable imaging tools for monitoring chemotherapy in pancreatic cancer, and could improve our ability to distinguish viable tumor cells from scar tissue.

Abstract
Pancreatic cancer has an extremely poor prognosis, only a small minority of patients undergo a resection with curative intent. Chemotherapy and/or radiochemotherapy may improve this by prolonging survival or disease-free interval and improving resectability and the proportion of microscopically complete (R0) resections. With regard to prolonging survival, both in the postoperative adjuvant setting and in locally advanced disease, chemotherapy has a positive but limited effect on survival and may be considered standard. The role of postoperative adjuvant radiochemotherapy remains debatable. For improving resectability/proportion of R0 resections, many studies suggest that the proportion of patients undergoing a resection during exploration and the proportion of R0 resections increase after neoadjuvant radiochemotherapy. This may improve the prognosis of patients with a resectable or borderline resectable pancreatic carcinoma. The effect of neoadjuvant radiochemotherapy, if any, is modest. The search for better combinations, including targeted therapy, must continue. The interpretation of single-arm studies is hampered by (selection) biases. The reporting of pathology and study endpoints should be internationally standardized. To avoid biases in studies of patients with (borderline) resectable tumours, prospective parallel registration of all patients referred for surgery would help. Ultimately, randomized controlled phase III trials should establish the role of neoadjuvant radiochemotherapy. Thus, neoadjuvant radiochemotherapy has a potential benefit in resectable and borderline resectable pancreatic cancer, but better combinations are warranted.

Abstract
INTRODUCTION This systematic review and meta-analysis aims to characterize the surgically important benefits and complications associated with the use of neoadjuvant chemoradiotherapy for the treatment of both resectable and initially unresectable pancreatic cancer. Studies were identified through a systematic literature search and analyzed by two independent reviewers. Survival, peri-operative complications, death rate, pancreatic fistula rate, and the incidence of involved surgical margins were analyzed and subject to meta-analysis. METHODS Nineteen studies, involving 2,148 patients were identified. Only cohort studies were included. RESULTS The meta-analysis found that patients with unresectable pancreatic cancer who underwent neoadjuvant chemoradiotherapy achieved similar survival outcomes to patients with resectable disease, even though only 40% were ultimately resected. Neoadjuvant chemoradiotherapy was not associated with a statistically significant increase in the rate of pancreatic fistula formation or total complications. CONCLUSION Patients receiving neoadjuvant chemoradiotherapy were less likely to have a positive resection margin, although there was an increase in the risk of peri-operative death.

Abstract
INTRODUCTION This systematic review and meta-analysis aims to characterize the surgically important benefits and complications associated with the use of neoadjuvant chemoradiotherapy for the treatment of both resectable and initially unresectable pancreatic cancer. Studies were identified through a systematic literature search and analyzed by two independent reviewers. Survival, peri-operative complications, death rate, pancreatic fistula rate, and the incidence of involved surgical margins were analyzed and subject to meta-analysis. METHODS Nineteen studies, involving 2,148 patients were identified. Only cohort studies were included. RESULTS The meta-analysis found that patients with unresectable pancreatic cancer who underwent neoadjuvant chemoradiotherapy achieved similar survival outcomes to patients with resectable disease, even though only 40% were ultimately resected. Neoadjuvant chemoradiotherapy was not associated with a statistically significant increase in the rate of pancreatic fistula formation or total complications. CONCLUSION Patients receiving neoadjuvant chemoradiotherapy were less likely to have a positive resection margin, although there was an increase in the risk of peri-operative death.

Abstract
BACKGROUND Pancreatic cancer remains a devastating disease with a 5-year survival rate of less than 5%. Recent advances in diagnostic methods and therapeutic approaches have increased the possibility of improving the existing poor prognosis. DATA SOURCES English-language articles reporting early diagnosis and therapy of pancreatic cancer were searched from the MEDLINE and PubMed databases, Chinese-language articles were from CHKD (China Hospital Knowledge Database). RESULT The current literature about pancreatic cancer was reviewed from three aspects: statistics, screening and early detection, and therapy. CONCLUSIONS Early detection and screening of pancreatic cancer currently should be limited to high risk patients. Surgical resection is the only curative approach available, with some recent improvement in outcomes. Gemcitabine has been a standard treatment during the last decade. Gemcitabine-based combination treatment, especially combined with newer molecular targeted agents, is promising. The rationale for radiotherapy is controversial, but with the recent development of modern radiation delivery techniques, radiotherapy should be intensified. Patients with borderline pancreatic cancer could benefit from neoadjuvant therapy but more evidence is needed and the best neoadjuvant regimen is still to be determined.

Abstract
Several advances in genetics, diagnosis and palliation of pancreatic cancer (PC) have occurred in the last decades. A multidisciplinary approach to this disease is therefore recommended. PC is relatively common as it is the fourth leading cause of cancer related mortality. Most patients present with obstructive jaundice, epigastric or back pain, weight loss and anorexia. Despite improvements in diagnostic modalities, the majority of cases are still detected in advanced stages. The only curative treatment for PC remains surgical resection. No more than 20% of patients are candidates for surgery at the time of diagnosis and survival remains quite poor as adjuvant therapies are not very effective. A small percentage of patients with borderline non-resectable PC might benefit from neo-adjuvant chemoradiation therapy enabling them to undergo resection; however, randomized controlled studies are needed to prove the benefits of this strategy. Patients with unresectable PC benefit from palliative interventions such as biliary decompression and celiac plexus block. Further clinical trials to evaluate new chemo and radiation protocols as well as identification of genetic markers for PC are needed to improve the overall survival of patients affected by PC, as the current overall 5-year survival rate of patients affected by PC is still less than 5%. The aim of this article is to review the most recent high quality literature on this topic.

Abstract
PURPOSE The objective of this study was to determine the effect on resection rate and survival of neoadjuvant chemoradiotherapy for primarily unresectable locally advanced pancreatic carcinoma. METHODS A systematic review of recently published literature was performed. Resection rates and survival data were derived from reports published from 2000 onwards. Only recent studies, based on radiotherapy with standard dose and fractionation, have been analyzed. RESULTS Thirteen studies with a total of 510 patients met selection criteria. A resection rate of 8.3-64.2% was reported (median, 26.5%). Of the operated patients, 57.1-100% (median, 87.5%) had R0 tumor resection. Most papers reported occasional pathological complete responses (CR, 3.0-8.8%). When outcome in all patients was considered, median survival ranged from 9 to 23 (median, 13.3) months, comparing favorably with literature data based on concurrent chemoradiation alone (range, 8.6-13 months). Surprisingly, in patients with unresectable tumor at presentation, median survival after surgery ranged from 16.4 to 32.3 (median, 23.6) months. CONCLUSIONS The finding of a high proportion of R0 resection among all resections performed confirms the activity of neoadjuvant radiochemotherapy and should not be neglected. Based on these data, patients with unresectable pancreatic cancer without disease progression after chemoradiotherapy should be considered for radical surgery.

Abstract
BACKGROUND The most accepted treatment for locally advanced pancreatic adenocarcinoma (LAPA) is chemoradiotherapy (CRT). We sought to determine the benefit of pancreaticoduodenectomy (PD) in patients with LAPA initially treated by neoadjuvant CRT. METHODS From January 1996 to December 2006, 64 patients with LAPA (borderline, n=49; unresectable, n=15) received 5-fluorouracil-cisplatin-based CRT. Of the 64 patients, 47 had progressive disease at restaging. Laparotomy was performed for 17 patients, and PD was performed in 9 patients (resected group). Fifty-five patients had CRT followed by gemcitabine-based chemotherapy (unresected group). RESULTS The median survival and overall 5 years survival duration of all 64 patients were 14 months and 12%, respectively. The mean delay between diagnosis and surgical resection was 5.5 months. Mortality and morbidity from PD were 0% and 33%, respectively. The median survival of the resected group vs. the unresected group was 24 months vs. 13 months. Three specimens presented a major pathological response at histological examination. No involved margins were found and positive lymph nodes were found in one patient. Resected patients developed distant metastases. CONCLUSIONS PD after CRT was safe and resected patients had interesting survival rates. However, resected patients developed metastatic disease and new neoadjuvant regimens are needed to improve the survival of these patients.
