Melanoma; Renal Cell Carcinoma Clinical Trial
Official title:
Blood Drawing for Study of Peripheral Blood T-lymphocytes and Other Parameters in Patients With Metastatic Melanoma and Renal Cell Cancer With Spontaneous Regression
The purpose of this study is to collect blood and clinical data from patients with metastatic melanoma and renal cell cancer who have experienced spontaneous regression for studies of immune response and other factors that may influence these occurrences.
Spontaneous regression in patients with metastatic cancer is an incredibly rare event. It has been described after infection in cancer patients and also rarely in patients with renal cell cancer (usually after resection of the renal primary) and, less commonly, in patients with metastatic melanoma. Primary Objective To collect peripheral blood from patients with metastatic melanoma and renal cell cancer and spontaneous regression for studies of immune response and other studies. Secondary Objective To collect clinical data from subjects registered to this study. Clinical data collection will include demographics and cancer characteristics, history and treatment. ;
