ABSTRACT: Treatment of pancreatic ductal adenocarcinoma (PDAC) is increasingly multidisciplinary, with neoadjuvant strategies (chemotherapy, radiation, and surgery) administered in patients with resectable, borderline resectable, or locally advanced disease. The rational supporting this management is the achievement of both higher margin-negative resections and conversion rates into potentially resectable disease and in vivo assessment of novel therapeutics. International guidelines suggest an initial staging of the disease followed by a multidisciplinary approach, even considering the lack of a treatment approach to be considered as standard in this setting. This review will focus on both literature data supporting these guidelines and on new opportunities related to current more active chemotherapy regimens. An analysis of the pathological assessment of response to therapy and the potential role of target therapies and translational biomarkers and ongoing clinical trials of significance will be discussed.

ABSTRACT: Pancreatic ductal adenocarcinoma (PDAC) is a tumor with a poor prognosis, short overall survival and few chemotherapeutic choices. MicroRNAs (miRNAs) are non-coding, single-stranded RNAs of around 22 nucleotides involved in the pathogenic mechanisms of carcinogenesis and metastasis. They have been studied in many tumors in order to identify potential diagnostic, prognostic or therapeutic targets. In the current literature, many studies have analyzed the role of miRNAs in PDAC. In fact, the absence of appropriate biomarkers, the difficultly of early detection of this tumor, and the lack of effective chemotherapy in patients with unresectable disease have focused attention on miRNAs as new, interesting advance in this malignancy. In this review we analyzed the role of miRNAs in PDAC in order to understand the mechanisms of action and the difference between the onco-miRNA and the tumor suppressor miRNA. We also reviewed all the data related to the use of these molecules as predictive as well as prognostic biomarkers in the course of the disease. Finally, the possible therapeutic use of miRNAs or anti-miRNAs in PDAC is also discussed. In conclusion, although there is still no clinical application for these molecules in PDAC, it is our opinion that the preclinical evidence of the role of specific miRNAs in carcinogenesis, the possibility of using miRNAs as diagnostic or prognostic biomarkers, and their potential therapeutic role, warrant future studies in PDAC.

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 interest in liquid biopsy is growing because it could represent a non-invasive prognostic or predictive tool for clinical outcome in patients with pancreatic ductal adenocarcinoma (PDAC), an aggressive and lethal disease. In this pilot study, circulating tumor cells (CTCs), CD16 positive atypical CTCs, and CTC clusters were captured and characterized in the blood of patients with PDAC before and after palliative first line chemotherapy by ScreenCell device, immunohistochemistry, and confocal microscopy analysis. Gene profiles were performed by digital droplet PCR in isolated CTCs, five primary PDAC tissues, and three different batches of RNA from normal human pancreatic tissue. Welsh's

ABSTRACT: BACKGROUND: New chemotherapeutic regimens have improved survival for stage IV pancreatic ductal adenocarcinoma and occasionally major response of liver metastases can be observed. Aim of this work is to analyze the outcomes of patients undergoing primary chemotherapy for liver metastases from pancreatic cancer and to evaluate the results of surgical resection. METHODS: Retrospective analysis. EXCLUSION CRITERIA: patients with extra-hepatic metastases, patients with Eastern Cooperative Oncology Group performance status ≥3, patients undergoing supportive care alone. RESULTS: 127 patients were identified. Liver metastases were unilobar in 28.5% of patients. Chemotherapy regimens included gemcitabine alone or in association with other agents (44%), oxaliplatin, irinotecan, fluorouracil and leucovorin (FOLFIRINOX 8%), and cisplatin, gemcitabine plus capecitabine and epirubicin (PEXG) or capecitabine and docetaxel (PDXG) or epirubicin and fluorouracil (PEFG) (48%). 56 patients (44%) had a complete (7%) or partial response (37%). surgical resection was carried out in 11 patients (8.5%). Median overall survival was 11 months for the entire cohort and 15 months for those with partial/complete response. In this sub-group median survival was significantly longer (46 versus 11 months) for patients undergoing resection (P < 0.0001). Independent predictors of overall survival were chemotherapy with multiple agents (HR: 0.512), surgical resection (HR: 0.360), >5 liver metastases at diagnosis (HR: 3.515), and CA 19.9 reduction < 50% of baseline value (HR: 2.708). CONCLUSIONS: Surgical resection of primary pancreatic tumor with or without residual liver disease can be considered in selected cases after primary chemotherapy and it is associated with improved survival.

ABSTRACT: AIMS: To evaluate potential differences at a molecular level between KRAS mutant tumors (MT) and KRAS wild-type (WT) pancreatic tumors and the biological and prognostic significance of different KRAS mutations. MATERIALS & METHODS: Expression of a panel of 29 genes was analyzed in KRAS WT and MT tumors. Effects of KRAS mutation and gene expression levels were assessed on patients' survival. RESULTS: MUC6 (p = 0.009), HGF (p = 0.011), VEGFR-2 (p = 0.020) and VEGFB (p = 0.026) were significantly more expressed and SMAD4 was less suppressed (p = 0.003) in WT KRAS. Contrariwise, SHH (p = 0.012) and IHH (p = 0.031) were more expressed in MT KRAS patients. No OS difference was found between WT and MT KRAS tumors. CONCLUSION: KRAS mutation status seems to identify two different subtypes of pancreatic ductal adenocarcinoma with similar outcome but distinct molecular features and probably different therapeutic targets.

7 Article HER family receptor expression and prognosis in pancreatic cancer. 2015

Bittoni, Alessandro / Mandolesi, Alessandra / Andrikou, Kalliopi / Santoni, Matteo / Alfonsi, Simona / Lanese, Andrea / Loretelli, Cristian / Pellei, Chiara / Piva, Francesco / Scarpelli, Marina / Cascinu, Stefano. ·Department of Medical Oncology, AOU United Hospitals, Polytechnic University of Marche, Ancona - Italy. ·Int J Biol Markers · Pubmed #26109364.

ABSTRACT: BACKGROUND: HER family receptors play a key role in tumor progression in several malignancies, such as colorectal, lung or breast cancer. The aims of this study were to investigate expression of HER-1, HER-2 and HER-3 in pancreatic cancer (PC) samples and evaluate the association between HER-family receptor expression and patients' clinical outcomes. METHODS: Tissue samples from 91 PC patients were subjected to immunohistochemical staining to assess the expression of HER-1, HER-2 and HER-3. Semiquantitative scores of zero (no staining or staining in less than 10% of cancer cells), 1+, 2+ or 3+ were assigned to each sample based on the intensity of staining for HER receptors. Scores of 2+ or 3+ were defined as positive staining. RESULTS: HER-1 overexpression was observed in 41 out of 91 samples (45.1%), while HER-2 was not overexpressed in any of the analyzed samples. HER-3 was overexpressed in 37 samples (40.7%) and was found to be associated with advanced TNM stage. In particular, HER-3 was overexpressed in 12 out of 16 stage IV patients (75%) compared with only 33.3% of stage I-III patients (p = 0.02). Among 79 patients with available survival data, the 6 patients with strong HER-3 expression (score 3+) had a shorter survival compared with remaining patients (median overall survival 6.9 months vs. 12.3 months, respectively). CONCLUSIONS: HER-1 and HER-3 were found to be expressed in a significant proportion of PC patients. Strong HER-3 expression represents an indicator of poor prognosis in PC patients, being associated with advanced stage and shorter survival.

8 Article [Treatment of pancreatic cancer. Actuality and perspective]. 2015

ABSTRACT: Pancreatic ductal adenocarcinoma (PDAC) is still one of the deadliest solid malignancies, with an extremely poor prognosis, with a 1-year survival rate of approximately 20%. Low survival rates of PDAC mainly derive from late diagnosis, with only a minority of patients amenable to surgery, as well as high rates of relapse and lack of effective treatments for advanced disease stages. As a result, there is an urgent need for the development of new effective therapies. At present, the greatest step towards an improvement of treatment has been made with the introduction of two combination chemotherapy regimens, namely FOLFIRINOX (folinic acid, 5-fluorouracil, irinotecan and oxaliplatin) and gemcitabine/nab-paclitaxel. However, current research is also taking a multidirectional approach aiming at developing new treatment options, such as the use of agents targeting the oncogenic network signaling of KRAS or the extracellular matrix, as well as immune therapies.

9 Article Lgr5 expression, cancer stem cells and pancreatic cancer: results from biological and computational analyses. 2015

Andrikou, Kalliopi / Santoni, Matteo / Piva, Francesco / Bittoni, Alessandro / Lanese, Andrea / Pellei, Chiara / Conti, Alessandro / Loretelli, Cristian / Mandolesi, Alessandra / Giulietti, Matteo / Scarpelli, Marina / Principato, Giovanni / Falconi, Massimo / Cascinu, Stefano. ·Medical Oncology, Polytechnic University of the Marche Region, School of Medicine, United Hospitals, Via Conca 71, 60126 Ancona, Italy. ·Future Oncol · Pubmed #25804119.

ABSTRACT: AIMS: To determine the relationship between Lgr5 and other stemness markers and pathologic features in pancreatic ductal adenocarcinoma (PDAC) samples. MATERIALS & METHODS: In 69 samples, Lgr5 was analyzed by qRT-PCR together with a panel of 29 genes. Bioinformatic analysis was carried out to identify a possible pathway regulating Lgr5 expression in PDAC. RESULTS: Lgr5 expression was not associated with the expression of tested cancer stem cell markers. Moreover, it was not an independent predictor of survival neither at univariate analysis (p = 0.21) nor at multivariate analysis (p = 0.225). CONCLUSION: Based on the lack of correlation between Lgr5 and tested cancer stem cell markers, Lgr5 does not seem to be a potential stemness marker or prognostic factor in PDAC.
