Pancreatic cancer has a dismal prognosis in the general population. However, early detection and treatment of disease in high-risk individuals can improve survival, as patients with localized disease and especially patients with lesions smaller than 10 mm show greatly improved 5-year survival rates. To achieve early detection through MRI surveillance programs, optimization of imaging is required. Advances in MRI technologies in both hardware and software over the years have enabled reliable detection of pancreatic cancer at a small size and early stage. Standardization of dedicated imaging protocols for the pancreas are still lacking. In this review we discuss state of the art scan techniques, sequences, reduction of artifacts and imaging strategies that enable early detection of lesions. Furthermore, we present the imaging features of small pancreatic cancers from a large cohort of high-risk individuals. Refinement of MRI techniques, increased scan quality and the use of artificial intelligence may further improve early detection and the prognosis of pancreatic cancer in a screening setting., (© 2024.

Colorectal cancer (CRC) has a very high incidence in the western world. Data from registries in the Middle East showed that the incidence of CRC is relatively low in these countries. However, these data also showed that CRC incidence has increased substantially over the past three decades and that a high proportion of cases are diagnosed at an early age (<50 years). In view of these findings, more attention should be paid to prevention. Because of the often limited financial resources, focused screening of individuals with hereditary CRC, in particular those with Lynch syndrome, appears to be the most cost-effective strategy. During recent meetings of the Palestinian Society of Gastroenterology and the Mediterranean Task force for Cancer Control (MTCC) in Jericho, and the Patient's Friends Society of Jerusalem in Hebron the issue of hereditary CRC in the Middle East was discussed and the idea was conceived to establish a network on hereditary colorectal cancer (HCCN-ME) with the goal of improving care for high-risk groups in the Middle East and (Eastern) Mediterranean Countries.

A family history of prostate cancer (PCa) is an established risk factor for PCa. In case of a positive family history, the balance between positive and adverse effects of prostate-specific antigen (PSA) testing might be different from the general population, for which the European Randomized Study of Screening for Prostate Cancer (ERSPC) showed a beneficial effect on mortality. This, however, went at the cost of considerable overtreatment. This study assessed Dutch physicians' knowledge of heredity and PCa and their 'post-ERSPC' attitude towards PCa testing, including consideration of family history. In January 2010, all Dutch urologists and clinical geneticists (CGs) and 300 general practitioners (GPs) were invited by email to complete an anonymous online survey, which contained questions about hereditary PCa and their attitudes towards PCa case-finding and screening. 109 urologists (31%), 69 GPs (23%) and 46 CGs (31%) completed the survey. CGs had the most accurate knowledge of hereditary PCa. All but 1 CG mentioned at least one inherited trait with PCa, compared to only 25% of urologists and 9% of GPs. CGs hardly ever counseled men about PCa testing. Most urologists and GPs discuss possible risks and benefits before testing for PCa with PSA. Remarkably, 35-40% of them do not take family history into consideration. Knowledge of urologists and GPs about heredity and PCa is suboptimal. Hence, PCa counseling might not be optimal for men with a positive family history. Multidisciplinary guidelines on this topic should be developed to optimize personalized counseling.

Endometrial cancer is frequent in MMR-mutation carriers. Estimates of annual incidence rates have, however, been based on retrospective studies. The purpose of our study was to prospectively assess the incidence rates of endometrial cancer in women either having a mutation in one of the four MMR genes MLH1, MSH2, MSH6 or PMS2 (Mut+) or belonging to families meeting the revised Amsterdam criteria in which no MMR mutation was detected (Ams+). Eight out of 80 Mut+ (10%) contracted invasive endometrial cancer compared to 1/171 (0.6%) of the Ams+ (P = 0.0006). The annual incidence rate after first control was 2.5% in Mut+ and 0.2% in Ams+. Two of the 8 Mut+ women (25%) had synchronous gynaecological tumours. The numbers included did not allow for firm conclusions, but the results are in keeping with the notion that the inherited colon-endometrial cancer syndrome may be restricted to carriers of MMR mutations.

Background: The family-link approach of case finding is considered the fastest and most efficient approach to trace people with hereditary disease. Therefore, there is a need to understand if, why, and how people with hereditary non-polyposis colorectal cancer (HNPCC) inform their biological family., Aim: To explore people's perspective on informing one's biological family regarding a hereditary predisposition for HNPCC., Method: In-depth interviews were conducted with 30 people recruited from the database of the Netherlands Foundation for Detection of Hereditary Tumours (STOET). Interviews were transcribed and analyzed thematically., Findings: Disclosure was stimulated if people felt morally obliged to do so or when they anticipated regret if something happened because it is preventable. Motivation to disclose seemed to increase if there were, especially fatal, cancer cases in the family. Presence of external cues (e.g. professionals) appeared important for disclosure as well. Disrupted and tense family relations were reasons not to disclose, as well as young age of the message recipients and negative experiences at their first attempt to disclose (a novel finding). Disclosure was merely restricted to the nuclear family. A personal approach in this respect was preferred. With respect to content of the disclosure, participants reported to solely announce the presence of the hereditary defect and the possibility of testing. It was mostly considered the recipients' responsibility and own choice to obtain further (technical/medical) information.
