Leptomeningeal disease (LMD) occurs in 5 % of breast cancer patients. The aim of this study was to identify risk factors related to survival and time to development of LMD in breast cancer patients. A retrospective analysis of breast cancer patients with LMD, evaluated in MDACC between 1995 and 2011. 103 patients with diagnosis of breast cancer and LMD were identified (one male). The median age at LMD diagnosis was 49.2 years. 78.2 % had invasive ductal carcinoma. Hormone receptors (HRs) were positive in 55.3 % of patients, 47.4 % were human epidermal growth factor receptor 2-positive and 22.8 % were triple negative. 52 % of the patients were treated with WBRT, 19 % with spinal radiation, 36 % with systemic chemotherapy and 55 % with intrathecal chemotherapy. Estimated median overall survival from time of breast cancer diagnosis was 3.66 years. Median survival from time of LMD diagnosis was 4.2 months. Time from breast cancer diagnosis to LMD was 2.48 years. In multivariate analysis, HR status and stage at diagnosis were significantly associated with time to LMD diagnosis (p < 0.05). In triple negative patients, time to LMD was shorter. In patients who were HR positive, time to LMD was longer. Survival from LMD diagnosis was significantly associated with both treatment, as well as positive HR status (multivariate analysis p < 0.05). In conclusion LMD has dismal prognosis in breast cancer patients. HR status contributes to time to LMD diagnosis and survival from LMD diagnosis. The impact of treatment aimed at LMD cannot be ascertained in our retrospective study due to the inherent bias associated with the decision to treat.

Patients with gliomas are at risk of cerebrovascular accidents (CVA) with potential consequences on survival, function, and local tumor control. Our objective was to provide information about CVA in patients with gliomas and to estimate survival in this group. We reviewed all adult glioma patients with ischemic CVA at the University of Texas-M.D. Anderson Cancer Center from 2003 through 2014. We extracted demographic, clinical, imaging, treatment and outcome data. We used descriptive summary data and estimated or compared survival rates where appropriate. 60 of 6500 patients (0.1%) with high-grade (HGG, n = 47) or low-grade glioma (LGG, n = 13) had ischemic CVA Thirty-two (53%) patients had postoperative strokes, and 20 (33%) had CVA after 2 weeks of surgery. Forty-one patients (68%) had gross total resection. For HGG and CVA, the poststroke median overall survival was 17 months versus 61 months in LGG and CVA (P = 0.03; hazard ratio (HR): 2.8; 95% CI 1.07-4.60). Survival stratified by modified Rankin Scale grade was significant (X(2) = 9.8, P = 0.007). Five patients received bevacizumab before stroke onset; none responded to antiangiogenic therapy. There was no stroke-related death. At our institution for 10 years, ischemic CVA in glioma patients was a rare complication, clearly associated in half of cases to surgery, and with a variable negative impact on performance status and neurologic function. In this group, patients with more neurological deficits lived less. The survival difference between and within subgroups was most likely due to tumor grade. More research is necessary to improve prevention of postoperative stroke in glioma patients.
