Abstract:
A staging programme for detection of lymph node involvement before radical cystectomy has been carried out in 22 patients. The programme includes: intravenous pyelography, chest X-ray, abdominal sonography, bone scan, CT and MRI. Also an immunoscintigraphic examination using monoclonal anti-CEA antibody (TUMAK BW 421/26) was done in every patient. Preoperative lymph node staging using CT, MRI and immunoscintigraphy was compared with post-operative histological staging: a total of 5 patients were found to have lymph node involvement. In none of them had lymph node involvement been predicted on the basis of CT, MRI or immunoscintigraphy.
