Identification of Lynch Syndrome in Patients with Endometrial Cancer Based on a Germline Next Generation Sequencing Multigene Panel Test. Cancers (Basel) 2022; 14:cancers14143406. [PMID: 35884469 PMCID: PMC9316192 DOI: 10.3390/cancers14143406] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Revised: 07/11/2022] [Accepted: 07/12/2022] [Indexed: 12/04/2022] Open
Abstract
We aimed to investigate the prevalence and relative contributions of LS and non-LS mutations in patients with endometrial cancer in Korea. We retrospectively reviewed the medical records of 204 patients diagnosed with endometrial cancer who underwent a germline next generation sequencing multigene panel test covering MLH1, MSH2, MSH6, PMS2, and EPCAM at three tertiary centers. Thirty patients (14.7%) with pathogenic mutations (12 MLH1; 6 MSH2; 10 MSH6; 2 PMS2) and 20 patients (9.8%) with 22 unclassified variants (8 MLH1; 8 MSH2; 2 MSH6; 3 PMS2; 1 EPCAM) were identified. After excluding four close relatives of a proband, the prevalence of LS was 13.0% (26/200). Patients with LS were more likely than those with sporadic cancer to be younger at diagnosis (48 vs. 53 years, p = 0.045) and meet the Amsterdam II criteria (66.7 vs. 3.5%, p < 0.001). Non-endometrioid histology was more prevalent in patients with MSH6 or PMS2 mutations (41.7%) than those with MLH1 or MSH2 mutations (5.6%, p = 0.026). In this pre-selected cohort of endometrial cancer patients who underwent next generation sequencing, the prevalence of LS was 13%, thus supporting the use of gene panel testing for endometrial cancer patients.

Jung YJ, Kim HR, Kim MK, Lee EJ. A novel germline mutation in hMLH1 in three Korean women with endometrial cancer in a family of Lynch syndrome: case report and literature review. Hered Cancer Clin Pract 2021; 19:28. [PMID: 34082788 PMCID: PMC8176696 DOI: 10.1186/s13053-021-00185-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2021] [Accepted: 05/25/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Endometrial cancer is often the sentinel cancer in women with Lynch syndrome, among which endometrioid endometrial cancer is the most common. We found a Korean case of uterine carcinosarcoma associated with Lynch syndrome. And we reviewed 27 Korean women with endometrial cancer associated with Lynch syndrome already released in case report so far. CASE PRESENTATION The proband, a 45-year-old Korean woman received treatment for endometrioid adenocarcinoma. Her older sister and niece were treated for endometrioid adenocarcinoma and carcinosarcoma, respectively. Family history met the Amsterdam II criteria and immunohistochemical analysis revealed a loss of MLH1 and PMS2. They all harbored a previously unreported germline likely pathogenic variant in c.1367delC in MLH1. They underwent staging operations including total hysterectomy, bilateral salpingo-oophorectomy, pelvic/paraaortic lymph node dissection, and washing cytology. All three women were healthy without evidence of relapse for over 4 years. CONCLUSION This report indicates a novel germline c.1367delC variant in MLH1, and presents a Korean case of uterine carcinosarcoma associated with Lynch syndrome. Furthermore, the c.1757_1758insC variant in MLH1 was suggested as a founder mutation in Lynch syndrome in Korean women.
