The role of bipedal lymphangiography in testicular seminoma.
Determining the extent of intra-abdominal spread of testicular seminoma by radiographic studies is an essential step in planning rational treatment following orchidectomy. CT scanning is generally accepted as being superior to lymphangiography in assessing the retroperitoneal space. We reviewed the relative contribution of these two procedures in a retrospective analysis of 73 consecutive patients with testicular seminoma managed at Westmead Hospital between January 1980 and September 1987. Abdominal CT scans and bipedal lymphangiography (LAG) were carried out in 72 and 51 patients respectively, 50 patients undergoing both procedures. We found concordance between the two techniques to be 88%. Upstaging occurred in 5 patients using CT (10%), 7 patients using LAG (14%), and in 8 patients (16%) when both tests were utilised. Four patients were upstaged by both techniques while the remaining 4 patients were upstaged using one technique alone. Serum beta-HCG was not a reliable screen for residual disease. Residual disease in the few patients with an elevated serum beta-HCG was easily detected by CT scanning. We conclude that there is a continuing role for LAG in assessing patients with clinical Stage I seminoma when the abdominal CT scan is equivocal or normal.
