Summary

This study aimed to create lab models of a rare and aggressive cancer of the upper urinary tract. Researchers took tumor samples from 20 patients and tried to grow them in mice and on chicken egg membranes. The goal was to develop tools to test new treatments for this cancer, which often comes back after standard surgery.

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

The study population consists of patients treated consecutively at the Urology Andrology department of Nîmes University Hospital for high-grade carcinomas of the pelvis or renal ureter for whom a total nephroureterectomy has been indicated during a multidisciplinary meeting. The tumor samples used for our study come from specimens removed surgically. Patients must not have undergone any prior systemic treatment.

Inclusion Criteria: * Patients treated consecutively at the Urology Andrology Department of Nîmes University Hospital for high grade carcinoma of the pelvis or renal ureter with an indication for total nephroureterectomy decided during a multidisciplinary meeting. * Patient with a diagnosis of high-grade urothelial carcinoma of the pelvis or renal ureter confirmed by histology (biopsy, biopsy of the ureteroscopic) or by cytology with the presence of : * High-grade disease on ureteroscopic biopsy OR ; * High grade disease on urinary cytology AND infiltrating appearance of the renal pelvic wall / ureter on the scanner (the presence of hydronephrosis will be considered as pervasive by definition) with a negative cytoscopy. Exclusion Criteria: * Any patient who has undergone previous systemic treatment.
