Abstract
To determine the incidence of vinca alkaloid (VA)-induced cardiovascular autonomic neuropathy (CAN), neoplastic patients were studied. Thirty-three of them were receiving chemotherapy regimens including VA and 30 were receiving chemotherapy without VA and were considered controls. Abnormal variations in blood pressure on standing, heart rate during deep breathing and heart rate on standing was found in 27 (82%), 16 (48%) and 16 (48%) patients receiving VA vs. 9 (30%; P < 0.01), 3 (10%; P < 0.05) and 1 (P < 0.001) controls, respectively. Of 198 tests performed, 100 were abnormal in patients receiving VA (51%) vs. 33 of 180 tests in the controls (18%: P < 0.001). Although abnormal clinical or electrocardiographic tests for CAN appeared significantly more frequently in patients who received high doses of VA (P < 0.01), their incidence was not significantly different in patients .gtoreq. 60 yr of age, in those who received doxorubicin, or in those who showed abnormal deep tendon reflexes. The consequences of VA-induced CAN might be especially important for potentially curable cancer patients.
