Significant advances in early breast cancer detection and increased quality of care within developed countries resulted in longer than five years survival in almost 90% of women diagnosed and treated for breast cancer. One in twenty women diagnosed with breast cancer will develop a new primary non-breast malignancy within 10 years from initial diagnosis. Mutations in BRCA 1 i 2, RAD51C, MMR, p53, CDKN2A and 113insArg genes are linked with increased risk of breast cancer and other cancer sites. It seems that treatment modalities also play significant role in development of new primary malignancies. Tissues that receive higher doses of radiation during radiotherapy of breast cancer are under increased risk of developing new primary tumor, especially in younger women, ten years after the treatment. Chemotherapy may cause higher incidence of leukemia and myelodysplastic syndrome but lower overall risk for development of other malignancies. Connection between tamoxifen therapy and increased risk of endometrial cancer is well known and confirmed also in recent studies. The true mechanism of cancer development is still unclear. Significance of hereditary factors, possible common environmental risk factors or unwanted side effects of the specific anticancer treatments are yet to be discovered.

Hereditary endometrial carcinoma is associated with germline mutations in Lynch syndrome genes. The role of other cancer predisposition genes is unclear. We aimed to determine the prevalence of cancer predisposition gene mutations in an unselected endometrial carcinoma patient cohort. Mutations in 25 genes were identified using a next-generation sequencing-based panel applied in 381 endometrial carcinoma patients who had undergone tumor testing to screen for Lynch syndrome. Thirty-five patients (9.2%) had a deleterious mutation: 22 (5.8%) in Lynch syndrome genes (three MLH1, five MSH2, two EPCAM-MSH2, six MSH6, and six PMS2) and 13 (3.4%) in 10 non-Lynch syndrome genes (four CHEK2, one each in APC, ATM, BARD1, BRCA1, BRCA2, BRIP1, NBN, PTEN, and RAD51C). Of 21 patients with deleterious mutations in Lynch syndrome genes with tumor testing, 2 (9.5%) had tumor testing results suggestive of sporadic cancer. Of 12 patients with deleterious mutations in MSH6 and PMS2, 10 were diagnosed at age >50 and 8 did not have a family history of Lynch syndrome-associated cancers. Patients with deleterious mutations in non-Lynch syndrome genes were more likely to have serous tumor histology (23.1 vs 6.4%, P=0.02). The three patients with non-Lynch syndrome deleterious mutations and serous histology had mutations in BRCA2, BRIP1, and RAD51C. Current clinical criteria fail to identify a portion of actionable mutations in Lynch syndrome and other hereditary cancer syndromes. Performance characteristics of tumor testing are sufficiently robust to implement universal tumor testing to identify patients with Lynch syndrome. Germline multi-gene panel testing is feasible and informative, leading to the identification of additional actionable mutations.
