A novel lynch syndrome kindred with hereditary adrenal cortical carcinoma. (PubMed, Cancer Genet)
A review of the literature identifies an association between germline MSH2 mutations and ACC, suggesting a potential biological basis for carcinogenesis. This case highlights the importance of ACC screening for patients with Lynch Syndrome and a family history of adrenal cortical carcinoma due to the high mortality from this malignancy. This case also highlights the importance of separate germline and somatic testing for patients with a concerning personal or family history of cancers.

The guidelines for clinical practice for carriers of germline mutations in the Lynch syndrome predisposition genes MLH1, MSH2, MSH6, PMS2 and large deletions of EPCAM (4.2024). (PubMed, Klin Onkol)
The drafting of the guidelines was organized by the Oncogenetics Working Group of the Society for Medical Genetics and Genomics of J. E. Purkyně Czech Medical Society, in cooperation with representatives of oncology, oncogynecology, and gastroenterology. The guidelines are based on the current recommendations of the National Comprehensive Cancer Network (NCCN), European Society of Medical Oncology (ESMO) and take into account the capacity of the Czech healthcare system.

Germline mismatch repair gene mutations in children with tumors: a case series from two centers. (PubMed, Transl Pediatr)
A better diagnostic approach is to perform genetic testing to rule out the risk as early as possible when a newborn presents with cafe-au-lait spots, which are a typical feature of hereditary syndromes. Therefore, it is important to use germline genetic testing, combined with clinical phenotypic observation, to establish a diagnosis of a cancer susceptibility syndrome caused by an MMR gene mutation.

Endometrial Cancers with Low Level Microsatellite Instability: Classification Pitfalls and Practical Recommendations for Assigning Mismatch Repair Status by Next Generation Sequencing with MSIsensor and Ancillary Tests (USCAP 2024)
MSIsensor scores as low as 3.5% may represent true MMRd in EC tested by NGS. Further testing for MMRd is advised for MSIsensor scores between 3% and 30%, particularly if there is low tumor content or associated high TMB. In this setting, MMR IHC may have superior sensitivity for detection of MMRd compared to DNA-based assays.

Rare germline mutation and MSH2-&MSH6 + expression in a double primary carcinoma of colorectal carcinoma and endometrial carcinoma: a case report. (PubMed, Diagn Pathol)
In the case of a patient with double primary EC and CRC, a careful evaluation of the IHC and the genetic data was presented. The patient carried rare compound heterozygous variants, a germline missense mutation, and a somatic frameshift mutation of MSH6, combined with a novel somatic null variant of MSH2. Our study broadened the variant spectrum of double primary cancer and provided insight into the molecular basis for abnormal MSH2 protein loss and double primary carcinoma.

Construction of a risk stratification model integrating ctDNA to predict response and survival in neoadjuvant-treated breast cancer. (PubMed, BMC Med)
In this study, we established a chemotherapy predictive model with a non-invasive tool that is built based on genomic features, ctDNA status, as well as clinical characteristics for predicting pCR to recognize the responders and non-responders to NAC, and also predicting prognosis for DFS in breast cancer. Adding pretreatment ctDNA levels to a model containing gene profile mutation and clinical characteristics significantly improves stratification over the clinical variables alone.

Molecular and clinical characteristics of POLE/POLD1 alterations among patients with colorectal cancer. (ASCO-GI 2024)
POLE/POLD1 mutations frequently co-exist with MSI-H disease in CRC. Patients with MSS-CRC harboring POLE/POLD1 mutations represent a smaller subgroup of CRC (~1%). The incidence of POLE/POLD1 somatic mutations was more common among patients with colon cancer than those with rectal cancer.
