Overall, median time to brain recurrence was 25 months (range 1-274). see more All 290 patients received at least one up-front

Whole brain radiotherapy (WBRT) was the first chosen option in the majority of cases (n = 136, 47%), followed by chemotherapy (n = 66, 23%), surgery (n = 60, 21%) and SRS (n = 28, 10%) respectively. Among the 145 patients receiving a second-line WH-4-023 supplier treatment for BMs, chemotherapy and WBRT were the most used approach (51% and 36.5% respectively).

as first treatment, namely surgery or SRS, those with ≤ 3 brain lesions were 92% (n = 55/60) and 100% (n = 28/28) respectively. Among patients receiving WBRT and chemotherapy as up-front therapy, patients with > 3 BMs were 62% (n = 84/136) and 41% (n = 27/66).

Only Grape seed extract patients with BMs from the four most frequent primary cancers (NSCLC, breast, colorectal cancer, and melanoma, n = 253) were considered for analyses of time to brain progression and survival. At a median follow-up of 25 months (range 1-104) from detection of BMs, time to brain progression was 26 months (C.I. 95%: 23-29) and survival was 13 months (C.I. 95%: 10-16). At 1, 2 and 3 years, 52%, 26% and 12% of patients were still alive respectively. Median time to brain tumor progression was 11 months for either breast cancer (C.I. 95%: 7-14) and melanoma (C.I. 95%: 6-17), 9 months for NSCLC (C.I. 95%: 7-10) and 5 months (C.I. 95%: 2-8) for colorectal cancer (P =.03). The corresponding 1- and 2-year survival rate were 58 % and 36% for breast cancer (median survival 16 months, C.I. 95%: 11-20), 51% and 20% for NSCLC (median survival 12 months, C.I.95%: 9-16), 40% and 18% for melanoma (median survival 10 months, C.I. 95%:9-14) and 18% and 9% for colorectal cancer (median survival 6 months, C.I. 95%:1-12) respectively (P =.01) (Figure 1). Figure 1 Kaplan-Meier survival curves at 2 years according to primary tumor. Local approaches (surgery or SRS) demonstrated to be superior in terms of time to BM progression and survival compared to either WBRT and chemotherapy (P =.02 and P =.0001 respectively) (Table 4; Figure 2).
