Abstract:
OBJECTIVES:To evaluate the predictive value of growth patterns in patients undergoing sorafenib treatment for metastatic clear cell renal cell carcinomas (CCRCCs). METHODS:Forty-eight patients were analyzed, each of whom underwent nephrectomy and received sorafenib treatment for metastatic CCRCC. Progression-free survival (PFS) was predicted using pathologic parameters, including pathologic stage, Fuhrman nuclear grade (FNG), the presence of a sarcomatoid component, lymphovascular invasion, tumor necrosis, and growth pattern. RESULTS:Three (6%) patients showed partial response, 20 (42%) patients showed stable disease, and 25 (52%) patients showed progressive disease. Univariate analyses demonstrated that FNG, the presence of a sarcomatoid component, tumor necrosis, and growth pattern were significantly associated with PFS. In the multivariate analysis, growth pattern was the only parameter that was significantly and independently predictive of PFS. CONCLUSIONS:As a novel histologic prognostic parameter, growth pattern may be useful for predicting response to sorafenib treatment.
