Neoadjuvant BRAF‐targeted therapy in regionally advanced and oligometastatic melanoma

Current management of locoregional and oligometastatic melanoma is typically with surgery; however, some patients are unable to undergo resection due to location/size of their tumors and/or the anticipated morbidity of the surgery. While there are currently no established guidelines for neoadjuvant...

description Current management of locoregional and oligometastatic melanoma is typically with surgery; however, some patients are unable to undergo resection due to location/size of their tumors and/or the anticipated morbidity of the surgery. While there are currently no established guidelines for neoadjuvant therapy in melanoma, neoadjuvant BRAF‐targeted therapy may make resection more feasible. A retrospective analysis was conducted of 23 patients with BRAFV600‐mutant, stage III/IV melanoma treated with BRAF‐targeted therapy prior to surgery, with no adjuvant treatment. Surgical specimens, preoperative imaging, and clinical outcomes were evaluated. Results: Ten of 23 patients (44%) attained a pathologic complete response (pCR), with no correlation between RECIST response based on preoperative imaging and pathologic response. After a median of 43‐month follow‐up, only 1 patient (10%) with a pCR recurred, while 8 of 13 (62%) patients without a pCR recurred. Patients with a pCR had significantly improved relapse‐free (RFS) and overall survival (OS) compared to patients with residual tumor. Neoadjuvant BRAF‐targeted therapy is associated with a high pCR rate in patients with stage III‐IV melanoma, which may correlate with improved RFS and OS.
