Brief summary:
RATIONALE: Drugs used in chemotherapy, such as doxorubicin and gemcitabine, use different ways to stop tumor cells from dividing so they stop growing or die. Combining more than one drug may kill more tumor cells.

PURPOSE: This phase II trial is studying how well giving doxorubicin together with gemcitabine works in treating patients with locally recurrent or metastatic unresectable renal cell carcinoma (kidney cancer).

Detailed description:
OBJECTIVES:

* Determine the response rate of patients with locally recurrent or metastatic unresectable renal cell cancer with sarcomatoid features treated with doxorubicin and gemcitabine.
* Determine the progression-free survival and overall survival of patients treated with this regimen.
* Determine the toxic effects of this regimen in these patients.

OUTLINE: This is a multicenter study.

Patients receive doxorubicin intravenously (IV) and gemcitabine IV over 30 minutes on day 1. Patients also receive filgrastim (G-CSF) subcutaneously (SC) on days 2- or 3-10 or pegfilgrastim SC on day 2. Courses repeat every 2 weeks in the absence of disease progression or unacceptable toxicity.

After 6 courses, patients undergo a MUGA scan. Patients with a stable\* left ventricular ejection fraction (LVEF) continue therapy as above. Patients who reach a total doxorubicin dose of 450 mg/m\^2 and are found to have unstable cardiac function or who have an abnormal LVEF continue therapy with gemcitabine alone.

NOTE: \*Stable cardiac function is defined as no decrease more than 15% of LVEF in absolute number and LVEF at least 35% in total function by MUGA.

Patients are followed every 3 months for 2 years and then every 6 months for 1 year.

ACTUAL ACCRUAL: A total of 39 patients were accrued for this study.

Arms: arm 1: Doxorubicin was given at 50 mg/m² by IV slow push, followed by gemcitabine 1500 mg/m² IV infusion over 30 minutes on day 1. Patients will receive G-CSF at a subcutaneous dose of 5mcg/kg/day on days 2 or 3 to 10 or neulasta at a dose of 6mg on day 2. Growth factor must be administered as close as possible to 24 hours after the completion of chemotherapy. It is recommended that neulasta be administered only on day 2 due to its prolonged half-life. Cycles were repeated every 2 weeks.
Interventions: intervention 1: Doxorubicin intervention 2: Gemcitabine intervention 3: G-CSF (granulocyte-colony stimulating factor) intervention 4: Neulasta
