Special Issue Information

Dear Colleagues,

This collection is the second edition of the previous one "Diagnosis and
Treatment of Gastroenteropancreatic Neuroendocrine Neoplasms"
(https://www.mdpi.com/journal/cancers/special_issues/Gastroenteropancreatic_Neuroendocrine_Neoplasms).

This Special Issue focuses on the diagnosis and treatment of gastroenteropancreatic tumors, with world-leading experts in the field providing readers with contemporary treatment and diagnosis algorithms, as well as a glimpse into novel and evolving treatments.

Gastrointestinal pancreatic neuroendocrine neoplasms (GEP-Nets) present many diagnostic and therapeutic challenges due to their relative rarity and complexity. Therefore, the latest findings on biomarkers, peptide receptor-based therapy, imaging therapy, etc., for the treatment of gastroenteropancreatic tumors are exciting. We would like to invite an array of scientific readers to contribute their research to this Special Issue of Cancers, dedicated to the generic topic of the diagnosis and treatment of gastroenteropancreatic tumors, such as gastric neuroendocrine tumors, pancreatic neuroendocrine tumors and small intestinal neuroendocrine tumors.

We would like to thank you in advance for your enthusiastic participation in this exciting Special Issue of Cancers.

Prof. Dr. Peter Stålberg
Guest Editor

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cancers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Patient-derived xenograft (PDX) tumor models are essential for identifying new biomarkers, signaling pathways and novel targets, to better define key factors of therapy response and resistance mechanisms. Therefore, this study aimed at establishing pancreas carcinoma (PC) PDX models with thorough molecular characterization, and the identification of signatures defining responsiveness toward drug treatment. In total, 45 PC-PDXs were generated from 120 patient tumor specimens and the identity of PDX and corresponding patient tumors was validated. The majority of engrafted PDX models represent ductal adenocarcinomas (PDAC). The PDX growth characteristics were assessed, with great variations in doubling times (4 to 32 days). The mutational analyses revealed an individual mutational profile of the PDXs, predominantly showing alterations in the genes encoding KRAS, TP53, FAT1, KMT2D, MUC4, RNF213, ATR, MUC16, GNAS, RANBP2 and CDKN2A. Sensitivity of PDX toward standard of care (SoC) drugs gemcitabine, 5-fluorouracil, oxaliplatin and abraxane, and combinations thereof, revealed PDX models with sensitivity and resistance toward these treatments. We performed correlation analyses of drug sensitivity of these PDX models and their molecular profile to identify signatures for response and resistance. This study strongly supports the importance and value of PDX models for improvement in therapies of PC. Full article
