Abstract:

Objective: To investigate the clinical characteristics, treatment modalities and prognostic factors affecting patients with brain metastasis from ovarian epithelial cancer. Methods: A retrospective analysis was conducted on the clinical data of 20 patients with brain metastasis from epithelial ovarian cancer treated in the Affiliated Cancer Hospital of Zhengzhou University from September 2010 to March 2022. The clinical characteristics, treatment modalities and prognostic data of the patients were analyzed. Results: The average age of the 20 patients was(53.5±9.6) years old at the time of diagnosis of ovarian cancer and (55.7±10.4) years old at the time of diagnosis of brain metastasis, and the median time between diagnosis of ovarian cancer and diagnosis of brain metastasis was 25 (2~116) months. 15 cases (75%) of ovarian plasma carcinoma and 2 cases (10%) of clear cell carcinoma were diagnosed, 15 cases (75%) were stage Ⅲ-Ⅳ, 19 cases (95%) underwent tumor cytoreduction, and 13 cases (65%) had residual tumor ≥1 cm in diameter after the initial surgery. Platinum sensitivity at the time of diagnosis of brain metastases was observed in 12 patients (60%), and clinical symptoms were observed in 16 patients (80%), with the most common symptoms being headache (7 cases) and vertigo (6 cases). 6 patients (30%) received single-modality therapy, and 14 patients (70%) received multimodal therapy. The median survival time of patients after brain metastasis was 12 (1~80) months. Univariate Cox regression analysis showed that clear cell carcinoma of the ovary, residual tumor≥1 cm in diameter after initial surgery, platinum resistance at the time of diagnosis of brain metastases, and extracranial tumors at progression at the time of brain metastases increased the risk of death; multimodal treatment reduced the risk of death. The results of multivariate Cox regression analysis showed that platinum resistance at the time of diagnosis of brain metastasis was an independent risk factor affecting patient survival. Conclusions: The prognosis of patients with brain metastases from ovarian epithelial cancer is affected by multiple factors, and multimodal treatment strategies can reduce the risk of death.
