This paper summarizes the current knowledge of gynecological care aspects in women with inherited predisposition to breast and ovarian cancer, i.e. BRCA1 and BRCA2 mutation carriers, and proposes guidelines for furher management of these women, addressing follow-up recommendations, prophylactic surgery indications and preimplantation genetic conseling. It evaluates cancer risk and severity of ovarian cancer in particular with regards to its high mortality resulting from aggressive biological behavior of the tumor and late detection rates. BRCA-positive women should be enrolled in prevention programs including carefull surveillance, prophylactic surgery or pre-implantation genetic counseling. Follow-up care consists of gynecological examination, expert oncogynecological ultrasound and tumor marker CA125 examination every six months. However, the most effective strategy for mortality reduction in ovarian cancer is prophylactic surgery--salpingo-oophorectomy (and hysterectomy). The optimal age for surgery is between 35 to 40 years. Prophylactic salpingo-oophorectomy performed in premenopausal women was proved to reduce the risk of ovarian as well as breast cancer. Symptoms of estrogen deficiency after prophylactic surgery can be suppressed by administration of hormone replacement therapy without increasing the risk of breast cancer. Preimplantation genetic diagnosis is an effective way to prevent the trans--mission of hereditary predisposition to the next generation. The management of patients with hereditary suspceptibility to ovarian cancer should be confined to specialized centres.
本文总结了遗传性乳腺癌和卵巢癌易感性女性(即BRCA1和BRCA2突变携带者)在妇科护理方面的现有知识,并针对这些女性的进一步管理提出了指导方针,涉及随访建议、预防性手术指征和植入前遗传咨询。本文特别评估了卵巢癌的癌症风险和严重程度,这与其肿瘤侵袭性生物学行为导致的高死亡率以及低检出率有关。BRCA阳性女性应纳入预防计划,包括仔细监测、预防性手术或植入前遗传咨询。随访护理包括每六个月进行一次妇科检查、专业的肿瘤妇科超声检查和肿瘤标志物CA125检查。然而,降低卵巢癌死亡率的最有效策略是预防性手术——输卵管卵巢切除术(及子宫切除术)。手术的最佳年龄在35至40岁之间。事实证明,对绝经前女性进行预防性输卵管卵巢切除术可降低卵巢癌和乳腺癌的风险。预防性手术后雌激素缺乏的症状可通过激素替代疗法得到缓解,而不会增加乳腺癌风险。植入前基因诊断是防止遗传易感性传给下一代的有效方法。对卵巢癌遗传易感性患者的管理应局限于专业中心。
