We evaluated the role of a collaborative specialist multidisciplinary team meeting (MDM) for familial and hereditary CRC, led by the St Mark's Hospital Centre for Familial Intestinal Cancer specifically in supporting the clinical management of uncertainty. A retrospective thematic analysis of meeting outcomes from inception in June 2020 until March 2023 was performed. Descriptive statistics were employed to ascertain clinicopathological data, clinical queries and whether MDM recommendations were outside the scope of current guidelines. In total 260 cases were discussed from 13 regional institutions. A prior personal history of cancer was present in 215 (82.6%), and a family history of CRC in 107(41.2%) and non-CRC 27(10.4%) cases. In thematic analysis uncertainty related to indications for genetic testing was considered in 148 (56.9%) of cases, with unexplained mismatch repair deficiency (u-dMMR) in 78 (30%) of cases, and resolution of molecular interpretation in 61 (23.5%). Surveillance related queries represented 55 (21.1%), and mainstreaming 29 (11%) of cases. Management was recommended beyond the scope of existing guidelines in 64 (24.6%) cases. This regional hereditary CRC MDM provides clinicians with support in areas of uncertainty in diagnosis and clinical management, supporting clinical decision-making where evidence and clinical guidelines may be limited.

The uptake of cascade testing is typically meditated by the proband's willingness to disclose their results with family members. Of which, cascade testing uptake rates in Singapore has been low, compared to global rates. Studies suggest that healthcare providers (HCPs)-meditated contact of at-risk family improves uptake, yet few have explored how receptive probands and family members are to such a model. Moreover, no studies to date have examined such a model of cascade testing in Asia. To address this gap, we interviewed 17 participants (probands and relatives) in Singapore to evaluate the acceptability and feasibility of HCP-mediated cascade testing for families with LS. Our findings show broad acceptability for HCP-mediated disclosure to relatives, driven by a sense of beneficence. However, HCP involvement introduced three unique issues to disclosure process: (i) their clinical position, which conveys expertise and authority; (ii) relational complexities within family dynamics; and (iii) the notion of family-centric privacy. We propose that HCP-mediated disclosure may be best implemented through a cooperative and flexible process, tailored to each family's unique circumstances. This approach balances the efficiency of providing accurate genetic information whilst sensitively navigating familial relationships, thereby improving uptake while respecting cultural and relational nuances.","PeriodicalId":12336,"journal":{"name":"Familial Cancer","volume":"24 1","pages":"25"},"PeriodicalIF":1.8,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143515098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CDKN1B encodes p27Kip1, a cyclin-dependent kinase inhibitor that acts as tumor-suppressor. Clinical presentation of MEN4 is similar to multiple endocrine neoplasia type 1 (MEN1) but the diagnosis of MEN4 can only be established once a germline CDKN1B pathogenic variant has been confirmed. We describe a unique case presenting with two -rare endocrine conditions. A 59-year-old female patient was diagnosed with medullary thyroid cancer (MTC) without evidence of a germline pathogenic variant in the RET proto-oncogene. Five years later, she developed Cushing's disease. A heterozygous germline variant was identified in the CDKN1B gene, specifically c.536del (p.Prol179GlnfsTer46), corresponding to a single-nucleotide deletion at position 536. This variant induces a frameshift, leading to an alternative stop codon. Immunostaining of the pituitary and thyroid tumors revealed a weak nuclear expression of p27/Kip1 without significant differences of expression between tumor and non-tumoral tissues. The NGS panel (Oncomine Comprehensive Assay v3) performed in both MTC and pituitary tissues identified the germline CDKN1B variant, as well as a pathogenic missense somatic variant c.182 A > G, p.(Gln61Arg) in HRAS in the MTC, without any RET somatic pathogenic variant. Evaluation of loss of heterozygosity (LOH) in both MTC and pituitary tissues showed compatibility with copy-neutral LOH, although further evidence is required for definitive confirmation. In conclusion, we report a clinical case of MTC coexisting with MEN4 due to a novel CDKN1B germline heterozygote frameshift variant.","PeriodicalId":12336,"journal":{"name":"Familial Cancer","volume":"24 1","pages":"24"},"PeriodicalIF":1.8,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143500102","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Family history, traditional breast cancer risk factors, and specific genetic CHEK2 variants are risk modifiers in this setting and add complexity for surveillance and risk-reduction decisions. Here, we present a case series of Brazilian CHEK2 carriers affected by breast cancer.Methods: Patients evaluated in the Oncogenetics Department of Hospital Sírio-Libanês (Brasília, Brazil) between November 2017 and September 2021, who had a personal history of breast cancer and a germline genetic test with a pathogenic or likely pathogenic CHEK2 variant, were selected for case description. Clinical pearls and knowledge gaps were highlighted for each case.Results: Twelve women were included in this descriptive analysis. All patients had early-stage breast cancer. Most of them were diagnosed with breast cancer prior to age 50 (9/12) and had a close relative affected by breast cancer (9/12). Seven patients harbored intronic pathogenic variants. Clinical pearls included the following: lack of risk estimates for intronic CHEK2 variants among non-European ancestry CHEK2 carriers, environmental exposures as a risk modifier, notable non-breast cancer diagnosis at young ages, incidental germline finding during tumor profiling, breast cancer diagnosis before the recommended age of breast cancer screening, family history of breast cancer as a risk modifier, and clinical outcomes after breast cancer treatment.Conclusions: Improvements in cancer risk assessment and cancer prevention for CHEK2 carriers are still needed to overcome current clinical challenges on the management of these patients.","PeriodicalId":12336,"journal":{"name":"Familial Cancer","volume":"24 1","pages":"23"},"PeriodicalIF":1.8,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143448730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

RPS20 pathogenic variants are very rare with only five reported cases in the literature. We report in this work the retrospective germline analysis of RPS20 for 1035 consecutive patients with a personal and/or familial history suggestive of hereditary predisposition to CRC. Within this series, a pathogenic variant in known CRC genes was found in 15% of cases and we describe one RPS20 loss-of-function variant (NM_001146227.1:c.115_116del, p.(Leu39Aspfs*33)). This frameshift is the first reported de novo variant in CRC, it was identified in in a female patient diagnosed with rectal cancer at the age of 35, 11 adenomatous polyps in 5 years and breast cancer at the age of 43. RPS20 has an intriguing role in oncogenesis, acting as an oncogene or tumour suppressor depending on the context, and is also involved in Diamond-Blackfan anemia via gain of function or dominant negative variants. This is therefore a complex gene for genetic counselling and, given the rarity of RPS20 pathogenic variants, we emphasise the need to collect data to clarify the phenotypic spectrum of RPS20-associated cancers and thus improve management.","PeriodicalId":12336,"journal":{"name":"Familial Cancer","volume":"24 1","pages":"22"},"PeriodicalIF":1.8,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143370594","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
