Aims and objectives:
In clinical staging T0 means that a primary tumour was not found by any clinical methods. In post-surgical staging, however, pT0 means that the surgical specimen does not contain a tumour which has been detected by clinical methods and/or by a biopsy. Basically the cause of such discrepancies can be a diagnostic error of the clinician or the pathologist, a sampling error of the pathologists dissecting the surgical specimen and a spontaneous regression of the tumour. In uropathological tumours the most common causes of diagnostic discrepancies vary markedly from organ to organ.The majority of pT0 testicular tumours are burned out germ cell tumours. In cystectomy specimens pT0 bladder carcinomas are encountered after neoadjuvant therapy. pT0 in radical prostatectomies after a positive biopsy are mostly due to inadequate sampling.The majority of pT0 in nephrectomy specimens are pseudoneoplastic lesions which appear as a mass in radiological image. In adrenal gland pathology the problem of pT0 is not usually addressed.
