Pancreatic cancer is a highly malignant tumor, which is still a major global health problem. Chemotherapy and radiotherapy are regularly used in adjuvant therapy for pancreatic cancer but their therapeutic efficacy is limited.
Ca signaling of pancreatic acinar cells in malignant hyperthermia susceptibility
Geyer N, Diszházi G, Magyar ZÉ, Dienes B, Csáki R, Enyedi P, Madácsy T, Maléth J and Almássy J
Malignant hyperthermia susceptibility (MHS) and acute pancreatitis (AP) share a common cellular pathomechanism that is Ca-overload of the muscle fiber and the pancreatic acinar cell (PAC). In the muscle, gain-of-function mutations of the ryanodine receptor (RyR1) make the Ca-release mechanism hypersensitive to certain ligands, including Ca, volatile anaesthetics and succinylcholine, creating a medical emergency when the patient is exposed to these drugs. As RyR1 was shown to contribute to Ca-overload in PAC, we presumed that pancreata of MHS individuals are more prone to AP. Accordingly, a recent case study reported coincidence of MHS with recurrent AP, indicating a pathological link between the two diseases.

Survival analysis of the metastatic cohort of Italian Association of Medical Oncology (AIOM) GARIBALDI survey
Reni M, Giommoni E, Bergamo F, Cavanna L, Simionato F, Spada M, Di Marco M, Bernardini I, Cordio SS, Latiano T, Spallanzani A, Silvestris N, Cardellino GG, Bonomi M, Milella M, Luchena G, Tamburini E, Macchini M, Orsi G, Modesti M, Procaccio L, Santoni A, De Simone I, Caldirola L, Galli F and Pinto C
This analysis from the GARIBALDI study was aimed to address the role of center self-declared expertise, type and commitment on the overall survival (OS) of patients with metastatic Pancreatic Ductal Adenocarcinoma (mPDAC). Treatment-naïve patients ≥18-year with pathological diagnosis of mPDAC were enrolled. OS was defined as the time from chemotherapy start to death from any cause. The impact of clinical-demographic and centers characteristics on OS was evaluated using Cox models. Between July 2017 and October 2019, 473 patients enrolled in 43 centers were eligible for this analysis. Median age was 69.3 (first-third quartile 61.2-74.5); 46.1 % females; 90.8 % ECOG PS 0-1; 67.4 % had liver metastases; median CA19.9700.5 UI/mL (first-third quartile 77.5-6629.5). For 37.1 % of patients chemotherapy started <4 weeks from diagnosis; 69.9 % of patients received nab-paclitaxel + gemcitabine; 16.9 % gemcitabine alone; 7.6 % FOLFIRINOX. The median follow-up was 51.8 months and 428 patients died. No statistically significant role of the type of institution was observed. Additionally, no statistically significant role of neither the self-declared expertise nor the accrual rate was observed. The GARIBALDI study suggests that the self-declared center expertise and the academic brand are not associated to OS in patients with mPDAC, while center commitment warrants further exploration.

Caveolin-1 expression is a predictor of survival and recurrence patterns in resected pancreatic ductal adenocarcinoma
Hirose Y, Oba A, Takamatsu M, Hamada T, Takeda T, Suzuki T, Maekawa A, Kitano Y, Sato S, Kobayashi K, Omiya K, Ono Y, Sato T, Ito H, Sasaki T, Ozaka M, Takeuchi K, Sasahira N, Inoue Y, Wakai T and Takahashi Y
Caveolin-1 (Cav1) expressed in cancer cells (cCav1) or cancer-associated fibroblasts (fCav1) exerts either pro- or anti-tumorigenic effects depending on the cancer type or stage of cancer. We aimed to clarify the impact of cCav1 or fCav1 on survival, recurrence patterns, and efficacy of neoadjuvant chemotherapy (NAC) in resected pancreatic ductal adenocarcinoma (PDAC).

Timing of lumen-apposing metal stents removal in pancreatic fluid collections: Could we go beyond?
Stigliano S, Marocchi G, Baldaro F, Neri B, Del Vecchio Blanco G, Troncone E and Di Matteo FM
Lumen-apposing metal stents (LAMS) are the mainstay treatment for pancreatic fluid collections (PFC). A 4-weeks interval for LAMS removal has been suggested to avoid adverse events (AEs). Primary aim is to evaluate the AEs rate in patients with LAMS removal <4 and >4 weeks from placement and possible associated factors.
Rs1347093 regulates microRNA-216/-217 expression and is associated with pancreatic cancer risk
Huang HH, Shiu TY, Chan DC, Chang CF, Lin HH, Lin JC, Chen PJ, Shih YL, Chang WK and Hsieh TY
Single nucleotide polymorphism (SNP) rs1347093 shows statistically significant association with lung cancer risk, but there is no further rs1347093 expression quantitative trait loci (eQTL) effect information. SNP rs1347093 is located in microRNA-216/-217 (miR-216/-217) locus. In addition, miR-216/-217 have pancreas-enriched expressions. In this study, we examined a potential miR-216/-217 promoter region, and investigated the effect of rs1347093-A allele on the miR-216/-217 promoter activity.
Early detection of pancreatic cancer: Study design and analytical considerations in biomarker discovery and early phase validation studies
Smith LM, Mahoney DW, Bamlet WR, Yu F, Liu S, Goggins MG, Darabi S, Majumder S, Wang QL, Coté GA, Demeure MJ, Zhang Z, Srivastava S, Chawla A, Izmirlian G, Olson JE, Wolpin BM, Genkinger JM, Zaret KS, Brand R, Koay EJ and Oberg AL
Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal disease that is challenging to detect at an early stage. Biomarkers are needed that can detect PDAC early in the course of disease when interventions lead to the best outcomes. We highlight study design and statistical considerations that inform pancreatic cancer early detection biomarker evaluation.
