Conditions

Clear Cell Renal Cell Carcinoma, Stage I Renal Cell Cancer

Brief summary

This pilot phase 0 trial studies how well enzalutamide works before surgery in treating patients with kidney cancer. Androgens are a type of hormone produced by the body that may cause kidney tumors to grow. Anti-hormone therapy, such as enzalutamide, may lessen the amount of androgens produced by the body and keep kidney tumors from growing.

Detailed description

PRIMARY OBJECTIVES: I. To investigate the effects of neoadjuvant enzalutamide on clear cell renal cell carcinoma (ccRCC). OUTLINE: Patients receive enzalutamide orally (PO) daily for 90 days in the absence of disease progression or unacceptable toxicity. Patients then undergo partial or radical nephrectomy. After completion of study treatment, patients are followed up every 3 months.

Intracrine androgen signaling levels of testosterone and dihydrotestosterone assessed in tissueUp to 36 monthsPre- and post-treatment tissue levels of testosterone and dihydrotestosterone will be compared to their respective serum levels to assess intracrine androgen signaling in ccRCC following enzalutamide treatment.
AR expression measured in pre- and post-treatment tissue samples by immunohistochemistry (IHC)Up to 36 monthsPre- and post-treatment ccRCC samples will be used to purify mRNA, construct cDNA, and perform qPCR to quantify expression of mRNA. IHC staining will be performed on ccRCC pre- and post-treatment.
