ABSTRACT: PURPOSE: Although surgery is the standard of care for resectable pancreatic cancer (PC), standard-dose chemoradiation therapy and chemotherapy alone are suitable for patients with unresectable disease. Stereotactic body radiation therapy (SBRT) is an alternative, focused local therapy that delivers high radiation doses within a few fractions to the cancer, sparing the surrounding critical tissue. We performed a systematic review and pooled analysis of published trials to evaluate the efficacy and safety of this emerging treatment modality. METHODS AND MATERIALS: We searched the Cochrane Central Register of Controlled Trials, PubMed, EMBASE, SCOPUS, the Web of Science, and CINAHL for publications regarding SBRT for locally advanced PC. The 1-year overall survival (OS) rate was the primary endpoint, and the median OS, 2-year OS rate, 1-year locoregional control (LRC) rate, and grade 3 to 4 toxicities were the secondary endpoints. A multivariate random-effects meta-analysis was performed to calculate the aggregated OS rates at 1 and 2 years and the 1-year LRC rate. RESULTS: A total of 19 studies, encompassing 1009 patients, were included in the present analysis. The pooled 1-year OS was 51.6% in 13 trials with data available. The median OS ranged from 5.7 to 47 months (median 17). The LRC rate at 1 year was 72.3%. Overall, the occurrence of severe adverse events did not exceed 10%. LRC appeared to correlate with the total SBRT dose and the number of fractions. CONCLUSIONS: The advantages of SBRT in terms of treatment time, satisfactory OS, and LRC indicate that it is an effective option for inoperable PC. However, a definitive validation of this treatment modality in large randomized studies is required, owing to the nonrandomized nature of the included studies and the limitations of small single-center series that include mixed populations.

ABSTRACT: BACKGROUND: Pancreatic ductal adenocarcinoma are known to metastasise early and a rationale exists for the investigation of preoperative chemotherapy in patients with resectable disease. We aimed to assess the role of combination chemotherapy in this setting in the PACT-15 trial. METHODS: We did this randomised, open-label, phase 2-3 trial in ten hospitals in Italy. We report the phase 2 part here. Patients aged 18-75 years who were previously untreated for pancreatic ductal adenocarcinoma, with Karnofsky performance status of more than 60, and pathologically confirmed stage I-II resectable disease were enrolled. Patients were randomly assigned (1:1:1), with a minimisation algorithm that stratified treatment allocation by centre and concentrations of carbohydrate antigen 19-9 (CA19-9 ≤5 × upper limit of normal [ULN] vs >5 × ULN), to receive surgery followed by adjuvant gemcitabine 1000 mg/m FINDINGS: Between Oct 5, 2010, and May 30, 2015, 93 patients were randomly allocated to treatment. One centre was found to be non-compliant with the protocol, and all five patients at this centre were excluded from the study. Thus, 88 patients were included in the final study population: 26 in group A, 30 in group B, and 32 in group C. In the per-protocol population, six (23%, 95% CI 7-39) of 30 patients in group A were event-free at 1 year, as were 15 (50%, 32-68) of 30 in group B and 19 (66%, 49-83) of 29 in group C. The main grade 3 toxicities were neutropenia (five [28%] of 18 in group A, eight [38%] of 21 in group B, eight [28%] of 29 in group C before surgery, and ten [48%] of 21 in group C after surgery), anaemia (one [6%] in group A, four [19%] in group B, eight [28%] in group C before surgery, and five [24%] in group C after surgery), and fatigue (one [6%] in group A, three [14%] in group B, two [7%] in group C before surgery, and one [5%] in group C after surgery). The main grade 4 toxicity reported was neutropenia (two [11%] in group A, four [19%] in group B, none in group C). Febrile neutropenia was observed in one patient (3%) before surgery in group C. No treatment-related deaths were observed. INTERPRETATION: Our results provide evidence of the efficacy of neoadjuvant chemotherapy in resectable pancreatic ductal adenocarcinoma. Since the trial began, the standard of care for adjuvant therapy has altered, and other chemotherapy regimens developed. Thus, we decided to not continue with the phase 3 part of the PACT-15. We are planning a phase 3 trial of this approach with different chemotherapy regimens. FUNDING: PERLAVITA ONLUS and MyEverest ONLUS.

ABSTRACT: Although lactate dehydrogenase (LDH) serum levels, indirect markers of angiogenesis, are associated with a worse outcome in several tumours, their prognostic value is not defined in pancreatic cancer. Moreover, high levels are associated even with a lack of efficacy of tyrosine kinase inhibitors, contributing to explain negative results in clinical trials. We assessed the role of LDH in advanced pancreatic cancer receiving sorafenib. Seventy-one of 114 patients included in the randomised phase II trial MAPS (chemotherapy plus or not sorafenib) and with available serum LDH levels, were included in this analysis. Patients were categorized according to serum LDH levels (LDH ≤ vs.> upper normal rate). A significant difference was found in progression free survival (PFS) and in overall survival (OS) between patients with LDH values under or above the cut-off (PFS: 5.2 vs. 2.7 months, p = 0.0287; OS: 10.7 vs. 5.9 months, p = 0.0021). After stratification according to LDH serum levels and sorafenib treatment, patients with low LDH serum levels treated with sorafenib showed an advantage in PFS (p = 0.05) and OS (p = 0.0012). LDH appears to be a reliable parameter to assess the prognosis of advanced pancreatic cancer patients, and it may be a predictive parameter to select patients candidate to receive sorafenib.

ABSTRACT: The clinical management of pancreatic ductal adenocarcinoma (PDAC) is hampered by the lack of reliable biomarkers. This study investigated the value of soluble stroma-related molecules as PDAC biomarkers. In the first exploratory phase, 12 out of 38 molecules were associated with PDAC in a cohort of 25 PDAC patients and 16 healthy subjects. A second confirmatory phase on an independent cohort of 131 PDAC patients, 30 chronic pancreatitis patients, and 131 healthy subjects confirmed the PDAC association for MMP7, CCN2, IGFBP2, TSP2, sICAM1, TIMP1, and PLG Multivariable logistic regression model identified biomarker panels discriminating respectively PDAC versus healthy subjects (MMP7 + CA19.9, AUC = 0.99, 99% CI = 0.98-1.00) (CCN2 + CA19.9, AUC = 0.96, 99% CI = 0.92-0.99) and PDAC versus chronic pancreatitis (CCN2 + PLG+FN+Col4 + CA19.9, AUC = 0.94, 99% CI = 0.88-0.99). Five molecules were associated with PanIN development in two GEM models of PDAC (PdxCre/LSL-Kras
