Abstract:
e22009 Background: According to the clinical studies, the frequency of melanoma brains metastasis reaches 43%, and according to autopsy data, this percentage is even higher - up to 75%. New drugs in clinical practice has significantly improved the prognosis of the metastatic melanoma, however, patients with metastases in the brain are often excluded from large clinical studies, which limits the evidence base of the effectiveness of new therapy methods in this category of patients. Methods: 44 patients with advanced melanoma were treated in SPb Clinical Oncology Dispensary from 2012 till now: 19 male and 25 female, median age is 54y.o. (from 26 to 81). 31 (70%) patients received combination of BRAF and MEK inhibitors, 13 (30%) patients received only BRAF inhibitors. 26 (59%) of patients received target therapy (TT) as 1st line of therapy. Initial performance status (PS) assessed by ECOG scale was following; 8 patient had PS = 0 by ECOG, 29 patients – PS = 1 by ECOG and 6 patients had PS = 2/3 status by ECOG. 8 (18%) patients with brain metastasis has radiation before the TT: 6 patients received at least 1 session of stereotactic radiotherapy and 2 patients underwent radiation of the entire brain. Results: Group of patients without brain metastases: median PFS is 10.0 month (95% CI: 6.0;15.0). The average PFS is 16,90 ± 3,19 month (95% CI:10,64;23,16). Median OS is 15.0 months (95% CI: 11.0;64.0). The average OS is 33,16 ± 5,89 month (95% CI: 21,62 – 44,70). Group of patients with brain metastases: median PFS and OS is not reached. The average PFS is 17,86 +/- 3,3 month (95% CI: 11,42-24,33). The average OS is 20,31 ±2,86 month (95% CI: 14,71 - 25,92). Only 3 from 8 patients have PD after TT on the time of analysis. 5 patients are still alive. Conclusions: Our clinical experience demonstrates comparable efficacy of TT (PFS and OS) in patients with melanoma, regardless of the presence of metastatic brain disease. In the treatment of this category of patients, an integrated approach is very important, including both the use of targeted drugs and the conduct of surgical and radiotherapy. An equally important factor is the rapid onset of treatment.
