Summary of "BRCA Germline Mutations in Women With Uterine Serous Carcinoma-Still a Debate."


OBJECTIVE:
: To determine the incidence of BRCA1 and BRCA2 mutations in an enlarged series of uterine serous carcinoma (USC) patients and to determine whether patients with USC are associated with a personal or familial history of breast or ovarian carcinoma.
METHODS:
: A cohort of all consecutive patients with diagnosed USC was identified for 9 years. Family pedigrees were drawn as far back and laterally as possible. In all patients, genomic DNA was extracted from peripheral blood samples and analyzed for the 3 mutations common in Ashkenazi Jewish patients. All patients went through total abdominal hysterectomy, bilateral salpingo-oophorectomy, and omentectomy. Tubal, ovarian, and peritoneal carcinoma were ruled out clinically and pathologically in all patients.
RESULTS:
: Of 51 consecutive patients with USC in Ashkenazi Jews studied, we identified 13 patients (25.5%) who were previously found to have breast carcinoma, 17 patients (33.3%) who had a first-degree relative with breast or ovarian carcinoma, and 8 patients (15.7%) who were found to be carriers of 1 of the 3 BRCA germline mutations.
CONCLUSIONS:
: This series of USC patients, the largest consecutive series to date, suggests a higher incidence of BRCA carriers among Ashkenazi Jews as compared with the general population. This high rate of BRCA germline mutations in USC patients coupled with a high rate of personal and familial cancer histories may suggest that USC is associated with the hereditary breast-ovarian syndrome. This potential association of USC to the BRCA-associated cancer spectrum may have implications for the clinical management and intervention of unaffected BRCA1-2 germline mutation carriers. However, at the current time, there are insufficient data to provide evidence-based guidelines regarding the optimal timing or specific intervention to prevent cancers in these high-risk women.

Medical and Biotech [MESH] Definitions

A variant of well-differentiated epidermoid carcinoma that is most common in the oral cavity, but also occurs in the larynx, nasal cavity, esophagus, penis, anorectal region, vulva, vagina, uterine cervix, and skin, especially on the sole of the foot. Most intraoral cases occur in elderly male abusers of smokeless tobacco. The treatment is surgical resection. Radiotherapy is not indicated, as up to 30% treated with radiation become highly aggressive within six months. (Segen, Dictionary of Modern Medicine, 1992)

Any drug treatment modality designed to inhibit UTERINE CONTRACTION. It is used in pregnant women to arrest PREMATURE LABOR.

A malignancy arising in uterine cervical epithelium and confined thereto, representing a continuum of histological changes ranging from well-differentiated CIN 1 (formerly, mild dysplasia) to severe dysplasia/carcinoma in situ, CIN 3. The lesion arises at the squamocolumnar cell junction at the transformation zone of the endocervical canal, with a variable tendency to develop invasive epidermoid carcinoma, a tendency that is enhanced by concomitant human papillomaviral infection. (Segen, Dictionary of Modern Medicine, 1992)

Inflation of a balloon catheter within the uterine cavity to control UTERINE HEMORRHAGE.

Genes encoding the different subunits of the IMMUNOGLOBULINS, for example the IMMUNOGLOBULIN LIGHT CHAIN GENES and the IMMUNOGLOBULIN HEAVY CHAIN GENES. The heavy and light immunoglobulin genes are present as gene segments in the germline cells. The completed genes are created when the segments are shuffled and assembled (B-LYMPHOCYTE GENE REARRANGEMENT) during B-LYMPHOCYTE maturation. The gene segments of the human light and heavy chain germline genes are symbolized V (variable), J (joining) and C (constant). The heavy chain germline genes have an additional segment D (diversity).
