Analysis of Primary and Metastatic Tumors in Patients With Renal Cell Carcinoma and Urothelial Carcinoma
- Conditions
- Renal Cell CarcinomaUrothelial CarcinomaBladder CancerUreter CancerUrethral Cancer
- Interventions
- Biological: Immune checkpoint inhibitor targeting PD1
- Registration Number
- NCT03291028
- Lead Sponsor
- Fox Chase Cancer Center
- Brief Summary
This is a comparative study using resected/ biopsied tumors samples collected from renal cell carcinoma and urothelial carcinoma patients who underwent surgical removal of lesions, followed by immune checkpoint blockade (ICB) treatment targting programmed cell death 1 (PD1) but developed new lesions later were also removed and stored in the biosample repository (BSR). The histology and genomic analysis of the pre-treatment and metastatic samples from the same patient would be used to find out the changes that may have lead to metastasis. Also, metastatic samples from ICB naive patients would be collected and compared with those from ICB treated patients to find out if the metastasis in treated patients was due to development of reistance.

Recruitment & Eligibility
- Status
- RECRUITING
- Sex
- All
- Target Recruitment
- 16
- Eligible patients will include retrospectively identified patients with RCC or UC who have received treatment with ICB and achieved clinical benefit but subsequently developed a solitary new/progressive lesion that was removed surgically. Patients with other tumor types who otherwise meet criteria may be included at a later time
- Additionally, a group of patients with RCC who have undergone a metastasectomy but who did not receive treatment with ICB will be identified. These patients may be approached for study participation to serve as a comparator group

- Primary Outcome Measures
Name Time Method Histopathological characterization of samples from ICB treated patients 18 months To characterize differences in histopathology and patterns of genomic expression between baseline tumors and metastases exhibiting divergent growth kinetics ("escape" metastases) in patients treated with immune checkpoint blockade (ICB)
Genomic characterization of samples from ICB treated patients 18 months To characterize expression of different genes between baseline tumors and metastases exhibiting divergent growth kinetics ("escape" metastases) in patients treated with immune checkpoint blockade (ICB)
- Secondary Outcome Measures
Name Time Method Comparison of genomic characteristics of metastatic samples from ICB naive and treated patients 18 months To characterize differences in patterns of genomic expression between "escape" metastases in patients treated with ICB from patients treated with targeted therapy or observation.
