Iliopelvic radionuclide lymphoscintigraphy in patients with testicular cancer
The utility of iliopelvic lymphoscintigraphy was assessed in 21 patients with testicular cancer (six seminoma patients, 15 nonseminoma patients). Normal lymphoscintiscans demonstrated symmetric uptake of technetium-99m-labeled radiocolloid throughout the lymphatic chain, from the internal iliac nodes to the level of the renal hilum. Signs of abnormality included decreased or no uptake of radionuclide in consecutive nodes of a lymphatic chain or in an entire lymphatic chain, and diminished uptake at the level of the renal hilum. In the 15 patients with nonseminomatous germ cell cancer, correlation of the results of scanning with pathologic specimens obtained upon dissection of retroperitoneal lymph nodes revealed a sensitivity of 0.89 an a specificity of 0.83. In the six patients with seminoma, there was good correlaton between scan findings and results of other radiologic tests. This study suggests that iliopelvic lymphoscintigraphy is a sensitive means of determining whether lymph node metastases are present in patients with testicular cancer.
