Potential Therapeutic Response In Urogenital Tumors

Preclinical models of urogenital carcinoma have been emerging as a way to pre-determine drug resistance before therapy is targeted. The implantation of tumor specimens in the chorioallantoic membrane (CAM) of the chicken embryo results in a high-efficiency graft, thus allowing large-scale studies of "tumor avatar". The aim of the study is to develop a tumor culture platform for treatment evaluation. Biopsies will be collected from primary tumors of patients and grafted onto the chorioallantoic membrane of chicken embryos. After tumor implantation at the CAM, tumor growth will be accompanied by imaging that will quantify tumor vascularization, tumor volume, and tumor blood flow. Following tumor growth, "avatars" will be divided into different treatments. Using the "tumor avatar" model together with patient tumors, the investigators will be able to observe the individualized tumor response for each patient in a treatment context, as well as determine the potential drug to be used in each case. These results may support a phenotype-based reading within 7-10 days.
