Lynch Syndrome –Associated Ovarian Cancer Presents Early, Has Good Prognosis

An analysis of Lynch syndrome –associated ovarian cancer found that the malignancy tends to present at an early stage and has a generally good prognosis.

With a great deal of interest we read the article entitled ” Hormone Replacement Therapy Prescription After Premature Surgical Menopause” by Garg et al [1]. They analysed a cohort of Sixty-three of which 20.6% had operation for gynaecological cancer including cervical cancer (1.6%), uterine cancer (14.2%), and ovarian cancer (4.8%).Other indications wer e BRCA carrier (17.4%), breast cancer (9.5%), Lynch syndrome (4.8%). Women treated for gynaecological or breast cancer or had BRCA gene mutations were less likely to use HRT.

In conclusion, somatic mutational signatures suggest that conventional MMR status of tumor tissues is likely to underestimate the significance of the predisposing MMR defects as contributors to breast tumorigenesis in LS. PMID: 32292574 [PubMed]

Mismatch repair deficiency (MMRD) is involved in the initiation of both hereditary and sporadic tumors. MMRD has been extensively studied in colorectal cancer and endometrial cancer, but not so in other tumors, such as ovarian carcinoma. We have determined the expression of mismatch repair proteins in a large cohort of 502 early-stage epithelial ovarian carcinoma entailing all the 5 main subtypes: high-grade serous carcinoma, endometrioid ovarian carcinoma (EOC), clear cell carcinoma (CCC), mucinous carcinoma, and low-grade serous carcinoma. We studied the association of MMRD with clinicopathologic and immunohistochemical ...

(Abstracted from Gynecol Oncol 2020;156:140–146) The 2 most common germline mutations causing cancer in the United States are BRCA1/2 mutations associated with hereditary breast and ovarian cancer (HBOC) and mismatch repair (MMR) gene mutations associated with Lynch syndrome (LS). A first-degree relative of a patient with one of these mutations incurs a 50% chance of inheriting the same mutation, and early detection can inform treatment and preventive procedures.

AbstractThe aims of the Prospective Lynch Syndrome Database (PLSD) are to provide empirical prospectively observed data on the incidences of cancer in different organs, survival following cancer and the effects of interventions in carriers of pathogenic variants of the mismatch repair genes (path_MMR) categorized by age, gene and gender. Although PLSD is assumption-free, as with any study the ascertainment procedures used to identify the study cohort will introduce selection biases which have to be declared and considered in detail in order to provide robust and valid results. This paper provides a commentary on the method...

Abstract About 23% of adnexal tumors are related to a hereditary syndrome, most often hereditary breast and ovarian cancer syndrome or Lynch syndrome, responsible of epithelial tumors. However, the pathologist should be aware of rare hereditary syndromes responsible of non-epithelial ovarian tumors. Ovarian tumors associated with germline mutation of BRCA genes are essentially high-grade serous carcinomas of tubal origin, while those seen in Lynch syndrome are most often endometrioid or clear cell carcinomas. Sex-cord tumors associated with a familial predisposition are Sertoli-Leydig cell tumors in DICER syndrome...

ConclusionThe patient presented represents the first reported case where both next generation sequencing (NGS) forBRCA LOH and MMR IHC testing of her breast cancer were performed and underscores the importance of using NGS including the reported mutational allelic frequency (MAF) and IHC use to predict the likely responsiveness to the recently approved PARP inhibitors and checkpoint inhibitor therapies (Robson et al in N Engl J Med 377:523 –533, 2017, Lemery et al in 377(15):1409–1412,https://doi.org/10.1056/NEJMp1709968, 2017), key because the gatekeeper transforming event for tumors related to inherited cance...

Eleven genes have been identified that increase the lifetime risk of developing ovarian cancer. The cumulative cancer risk of ovarian cancer varies with the mutation type and age. Ovarian cancer risk management options include surgical risk reduction with salpingo-oophorectomy and a newer step-wise approach with interval salpingectomy and delayed oophorectomy. Women should be counseled on the pros and cons of hysterectomy in the setting of reducing the risk of other cancers; eliminating the risk of endometrial cancer in Lynch Syndrome, potential risk of serous/serous-like endometrial cancer in BRCA1 carriers, and eliminati...
