Definition of Tumor Bio-markers and Physical-spectroscopic Differences Between Healthy Urothelial Tissue Healthy and Urothelial Cancer

Our multicenter observational study is a non-profit prospective study. The study was born from the Amplitude Project, which comprise the SOD of Minimally Invasive Robotic Urological Surgery and Renal Transplants of AOU Careggi with the University of Florence, as well as with the National Research Council (CNR) and the University of Milan Bicocca (UNIMIB) The study consists of a phase of enrollment of patients who will be admitted to the SOD of Mini Invasive Robotic Urological Surgery and Renal Transplantation of AOU Careggi. Enrollment in the study does not alter normal clinical practice and does not involve additional risks for patients. Patients will have to meet the inclusion and exclusion criteria of the study and will be enrolled sequentially, until the established sample size is reached. Patients undergoing surgery for the removal of bladder neoplasm, be it endoscopic or surgical with radical intent (cystectomy), will be taken a fragment of tumor bladder tissue, on which histopathological analysis will be performed. In patients undergoing radical cystectomy only, a fragment of healthy urothelial tissue, free from neoplasia, will also be removed. The samples will be performed in patients under general and / or spinal anesthesia in case of TURB, thus not causing pain or discomfort to the patient, or ex-vivo on the operative piece in case of radical cystectomy, without causing further damage or pain to the patient. From these samples, specially stored in solutions that keep their characteristics unaltered, a 3D culture model (organoid) will be obtained both from cells obtained from bladder cancer and from healthy tissue on which biomolecular, metabolomic and spectroscopic characterization studies will be tested and carried out. with a view to staging and grading bladder neoplasia.
