From 1974 to 1980, 69 patients with ith diffuse malignant mesothelioma were prospectively evaluated. The initial site of involvement was the pleura in 57 patients and the peritoneum in 12. Previous asbestos exposure was found in 53 patients (77%), with a shorter period of latency for peritoneal (mean, 28 years) than for ith pleural mesothelioma (mean, 35 years) than for pleural mesothelioma (mean, 35 years). Other associated exposure or diseases included talc, mica, familial Mediterranean fever, and diffuse lymphocytic lymphoma (one patient each). Thrombocytosis was common, as were thromboembolic episodes. Survival was significantly better for patients with an epithelial subtype, with pleural versus peritoneal mesothelioma, and for those under 65 years of age. Surgery was never curative, but its extent was correlated with survival and earlier diagnosis. Results of chemotherapy with doxorubicin and 5-azacytidine yielded a somewhat better survival rate than a combined program with doxorubicin and radiotherapy. Survival after chemotherapy was correlated with performance status, response to chemotherapy, and extent of previous surgery.
A patient with lymphosarcoma treated with weekly injections of vincristine developed an acute myocardial infarction immediately after the second injection of vincristine. After he recovered from the infarction, the treatment was continued and he developed an additional myocardial infarction. I n vivo and in vitro studies have not revealed any effect of vincristine on the clotting mechanism. T h e possible causes for the association of vincristine-treated lymphoma and myocardial infarction are discussed.Cancer 36:1979-1982, 1975. H E TOXIC EFFECT OF VINCRISTINE IS MAINLYT neurologic,4 manifesting as muscle weakness, paresthesia, loss of deep tendon reflexes, ptosis, diplopia, a n d hoarseness. Alopecia a n d constipation commonly occur. O t h e r rare side effects are inappropriate ADH secretion9 orthostatic hypotension,z a n d thrombocytosis.8To the best of o u r knowledge, myocardial infarction has n o t been mentioned i n t h e literature as a complication of vincristine administration.In this study we describe n case of myocardial infarction which developed i n a patient with lymphosarcoma after vincristine administration. CASE REPORTF.Z., a 58-year-old male originating from Rumania, was admitted to the Department because of lymphadenopathy and weakness of 1 month's duration. Two years previously, he had suffered a myocardial infarction and since then from mild angina pectoris. On physical examination the patient was found to be in good general condition, weighing 76 kg. He had no fever. Enlarged lymph T h e authors thank Miss van-der-Lyjn for her excellent technical assistance.Received for publication March 25. 1975. nodes, u p to 2 cm in diameter, firm, nontender, and nonadherent to skin were palpated in the neck and inguinal areas. T h e spleen and liver were not palpable. All laboratory findings, including complete blood count, renal and liver function tests were within normal limits. Electrocardiogram (ECG) on admission showed an absence of R waves in leads V, V, and Q wave in leads L,, aVF ( Fig. 1). A lymph node was hiopsied and the diagnosis of lymphosarcoma was established.Treatment with weekly injections of vincristine, according to an increasing dose schedule, was started. T h e first weekly injection of 3.8 mg was tolerated well. One hour after the second intravenous injection of 7.6 mg vincristine (0.1 mg/kg body weight) the patient complained of severe pressing precordial pain radiating to the left arm which lasted for 2 hours. His blood pressure was 130/80 mm mercury, the pulse rate 100 per minute with occasional extrasystoles. An ECG recording revealed T wave inversion in leads L, L,, aVL, V,V,, S T depression in V,-V,, S T elevation in L,, and premature ventricular contractions (Fig. 2).Examination of blood enzyme levels showed serum creatin phosphokinase (CPK) 5.0 Menashe-Gaist units (normal 0.9-3.0 units), lactic dehydrogenase (LDH) 476 King units (normal 100-250 units), and serum glutamic oxnloacetic transaminase (SGOT) 28 Sigms units (normal 15-40 units).T h e possibility of a vincrist...
