OBJECTIVES: Primary - To evaluate the response rate to sunitinib malate with vs without gemcitabine hydrochloride in patients with advanced renal cell carcinoma with sarcomatoid features. Secondary - To evaluate progression-free survival of these patients. - To evaluate overall survival of these patients. - To describe the toxic effects of both sunitinib malate alone and in combination with gemcitabine hydrochloride in these patients. OUTLINE: This is a multicenter study. Patients are stratified according to risk (good risk [clear cell and < 20% sarcomatoid and performance status (PS) 0] vs intermediate risk [20-50% sarcomatoid and PS 0] vs poor risk [non-clear cell or > 50% sarcomatoid or PS 1 or non-clear cell]). Patients are randomized to 1 of 2 treatment arms. - Arm I: Patients receive gemcitabine hydrochloride IV over 30 minutes on days 1, 8, 22, and 29 and oral sunitinib malate once daily on days 1-14 and 22-35. - Arm II: Patients receive oral sunitinib malate once daily on days 1-14 and 22-35. In both arms, courses repeat every 42 days for up to 1 year in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 1 year. PROJECTED ACCRUAL: A total of 100 patients (60 in arm I and 40 in arm II) will be accrued to this study.
