Ki-67 index and percentage of sarcomatoid differentiation were two independent prognostic predictors in sarcomatoid renal cell carcinoma

Sarcomatoid Transrormation of Chromophobe Renal Cell Carcinoma

Sarcomatoid differentiation in renal cell carcinoma: prognostic implications.

INTRODUCTION Renal cell carcinoma with sarcomatoid differentiation is a tumor with aggressive behavior that is poorly responsive to immunotherapy. The objective of this study is to report our experience in the treatment of 15 patients with this tumor. MATERIALS AND METHODS We retrospectively analyzed 15 consecutive cases of renal cell carcinoma with sarcomatoid differentiation diagnosed betwe...

Chromophobe Renal Cell Carcinoma with Sarcomatoid Differentiation

We report chromophobe renal cell carcinoma (CRCC) with sarcomatoid dedifferentiation in a sixty-five year old male. CRCC is a prognostically better, distinctive subtype of renal cell carcinoma (RCC), histologically characterized by cells containing translucent and reticulated cytoplasm with distinct cell borders. Sarcomatoid component accompanies 9% of CRCC which alters its prognostic implicati...

Sarcomatoid Chromophobe Renal Cell Carcinoma with Heterologous Component

Clear cellrenal cell carcinoma (RCC) is the most common malignant renal tumor in adults, while chromophobe RCC (CRCC) is the third most common. Any subtypes of RCC can undergo sarcomatoid differentiation, but heterologous differentiation in sarcomatoid area is very rare in RCC. Here a61-year male is presented with hematuria and palpable mass. Clinicoradiologically, RCC was considered and left r...
