Aim. To review strategies for prophylactic surgery in carriers of BRCA1 or BRCA2 gene mutations and their short and long-term outcomes regarding overall health and health-related quality of life.
Materials and methods. Between January 2007 and December 2018, 752 women with ovarian cancer were tested for the most common mutations of BRCA1 (5382insC, 4153delA, 185delAG, С61G, 2080delA, 3875del4, 3819del5) and BRCA2 (6174delT) genes using allele-specific PCR. Patients with suspected hereditary ovarian cancer (n = 327) or concurrent breast and ovarian cancer (n = 16) were identified. The entire coding sequences of BRCA1 and BRCA2 genes were analyzed in these patients using high-resolution analysis of melting PCR products followed by sequencing of fragments with abnormal denaturation curves.
Results. The study identified 97 patients with ovarian cancer who had common mutations of BRCA1 genes [5382insC in BRCA1 gene, 4153delA in BRCA1 gene, 185delAG in BRCA1 gene, and C61G in BRCA1 gene in 74 (76.3%), 13 (13.4%), 7 (7.2%), and 1 (1%) of patients, respectively], and BRCA1 gene C61G in 1 (1%), BRCA1 gene 2080delA in 2 (2.1%)) and two patients with the 617delLT mutation in the BRCA2 gene, as well as 19 patients with rare mutations: in the BRCA1 gene (n = 14) and the BRCA2 gene (n = 5). The following recurrent alleles of BRCA1 were identified among rare mutations: R1751X in 5 (35.7%), R1699W in 3 (21.4%), G1706E in 2 (14.3%), c.2643delA in 2 (14.3%), c.5215 + 1G> T in 2 (14.3%) (n = 2) and BRCA2: Y1762X in 2 (40%), and c. 6999dupA in 3 (60%). Among relatives who carried mutations, 2/72 (2.7%) were diagnosed with ovarian cancer and fallopian tube cancer. In healthy carriers of BRCA1 gene mutations, hysterectomy with adnexa removal and bilateral adnexectomy were performed in 5 (62.5%) and 3 (37.8%) patients, respectively. In all 8 cases of prophylactic surgery, no adenocarcinoma cells were detected in removed ovaries and fallopian tubes.
Conclusion. Thus, salpingectomy during various gynecological surgeries is safe and may offer protection against ovarian cancer without compromising endocrine function. Besides, a delayed salpingectomy strategy may also serve as an effective alternative preventive strategy for women with a genetic predisposition to ovarian cancer.
