title: Alterations in plasma sialyltransferase associated with successful chemotherapy of a disseminated tumor. Case report.
abstract: Levels of plasma sialyltransferase were measured in a  patient with disseminated carcinoma of the testes. Initial enzyme values, elevated six fold above those in normal controls, were among the highest thus far encountered in a population of patients with various stages and types of malignancy. During a remarkable respose to chemotherapy with cis-diaminodichloroplatinum, plasma sialyltransferase levels fell markedly. Serial measurement of this enzyme may aid in evaluation of tumor responsiveness to therapy in patients whose disease is not readily measurable.
