Metastases to the brain from ovarian and endometrial carcinoma are uncommon and to the authors' knowledge consensus regarding optimal management is lacking. Stereotactic radiosurgery (SRS) has proven useful for the treatment of many benign and malignant brain tumors. In the current study, the authors evaluated outcomes after SRS in patients with ovarian and endometrial carcinoma.
Twenty-seven patients with brain metastases underwent gamma-knife SRS. Six patients had endometrial carcinoma, whereas 21 patients had ovarian carcinoma. Eighteen patients also received whole-brain radiotherapy. A total of 68 tumors were treated with gamma-knife SRS.
At the time of last follow-up, 1 patient was still alive and 26 had died. The median survival was 7 months after the initial diagnosis of brain metastasis and 5 months after SRS. The 1-year survival rate after radiosurgery was 15% and that from the diagnosis of brain metastases was 22%. On final imaging, all tumors were controlled without further growth. Two patients (7.4%) developed new or progressive neurologic deficits after SRS.
SRS is an acceptable choice for the treatment of brain metastases resulting from ovarian and endometrial carcinoma, and provides local tumor control with limited morbidity. Careful patient selection is warranted in the setting of patients with uncontrolled systemic disease in whom a limited survival benefit is expected.
卵巢癌和子宫内膜癌脑转移并不常见,据作者所知,目前对于其最佳治疗方案仍缺乏共识。立体定向放射外科治疗(SRS)已被证明对许多良性和恶性脑肿瘤的治疗有效。在本研究中,作者评估了SRS治疗卵巢癌和子宫内膜癌脑转移患者的疗效。
27例脑转移患者接受了伽玛刀SRS治疗。其中6例为子宫内膜癌,21例为卵巢癌。18例患者还接受了全脑放疗。总共68个肿瘤接受了伽玛刀SRS治疗。
在最后一次随访时,1例患者仍存活,26例已死亡。脑转移初始诊断后的中位生存期为7个月,SRS治疗后的中位生存期为5个月。放射外科治疗后1年生存率为15%,脑转移诊断后的1年生存率为22%。在最后一次影像学检查时,所有肿瘤均得到控制,无进一步生长。2例患者(7.4%)在SRS治疗后出现新的或进行性神经功能缺损。
SRS是治疗卵巢癌和子宫内膜癌脑转移的一种可接受的选择,可实现局部肿瘤控制,且并发症发生率有限。对于全身疾病未得到控制、预期生存获益有限的患者,需要谨慎选择。
