La composizione del microbiota può influenzare la fertilità di uomini e donne

Transcription-replication conflicts (TRCs) are a key source of replication stress in cancer, with pancreatic ductal adenocarcinoma (PDAC) showing uniquely high levels. This study investigates the mechanism, oncogene dependency, subtype specificity, and preclinical activity of the TRC-targeting molecule AOH1996 in PDAC models. Initial clinical evidence of AOH1996 activity in PDAC patients is also provided.

Introduction
Pancreatic cancer is a devastating disease and one of the top causes of cancer death worldwide. Over 30% of cases are potentially avoidable, and while screening for this disease should be possible, the current methods, without risk stratification to detect high-risk groups, are unlikely to detect these individuals. A tailored screening pathway could be applied to individuals with a germline genetic cause of pancreatic cancer, which may account for around 10% of cases.

Methods and analysis
EUROPAC, although having international reach, is described here in relation to the UK only. This national prospective observational study has run for several decades but was modified into the current trial in 2019, which aims to recruit and screen 10 000 individuals with either familial pancreatic cancer or hereditary pancreatitis (HP). Applicants are assessed for eligibility by generating an individual pedigree and by attributing a family risk score (FR). Individual risk is assessed according to age. Individuals over 40 with an FR >30 are offered baseline imaging and then three yearly triplets of annual endoscopic ultrasound (EUS) and an MRI (in the third year). Those with an FR >60 are offered both EUS and MRI yearly. HP patients are screened by CT and/or MRI dependent on risk stratification using the presence of diabetes, smoking or alcohol consumption. Low-risk (absence of these factors) patients have a CT every 2 years, and high-risk (one or more of the above factors) patients have alternate yearly screening with CT, then MRI. Biospecimens are collected at pragmatic intervals with first sampling at registration to support future biomarker development to detect pancreatic cancer early. Detection of early-stage pancreatic cancer and actionable lesions will be evaluated.

Ethics and dissemination
The EUROPAC study has been reviewed and approved by the Yorkshire and Humber Research Ethics Committee (Ref 19/YH/0250). Study results will be disseminated through national and international symposium presentations and published in peer-reviewed, open-access journals. All participants provided informed consent prior to entering the study.

Metastatic cancers arise from a decades-long succession of increasingly virulent precursor lesions, each of which represents prospective targets for therapeutic intervention. This evolutionary process has been particularly vivid in esophageal adenocarcinoma (EAC), as this cancer and associated precursor lesions, including Barrett’s esophagus (BE), low-grade dysplasia (LGD), and high-grade dysplasia (HGD), co-exist in an accessible, two-dimensional pattern in esophageal mucosa. Given the durability of these precursor lesions, it is likely that they, like EAC, rely on stem cells for their regenerative growth.
