Background: There is debate on the timing and outcome of coronary artery bypass surgery in patients with coincident malignancy. In this study, we compared the outcome of coronary artery bypass graft (CABG) in such patients with those without malignancy. Methods: The patients were selected from those who had undergone coronary artery bypass surgery in the last decade. The study group (group I) included the patients with malignancy in remission. The control group comprised those patients who were selected randomly from those without any malignancy. The patients were retospectively examined with regard to preoperative, operative, and postoperative data from personal files, computerized recording system, and operation reports. Results: Group I included 48 patients (age 48 to 69; 29 male) while group II included 50 patients (age = 38 to 73; 35 male). In group I, comorbidity rates were: renal dysfunction in 12 (25%), obstructive lung disease 10 (21%), congestive failure in four (8%) patients. The malignancy rates were: lung in 15 (31%), breast in 10 (21%), stomach in five (10%), colon in four (8%), renal in one (2%), Hodgkin's lyphoma in three (6%), leukemia in two (4%), ovarian in three (6%), and prostate in five (10%) patients. In group II, the comorbidity rates were: diabetes mellitus 18 (36%), renal dysfunction in five (10%) and obstructive lung disease in 13 (26%) patients. In group I, chemotherapy and radiotherapy were performed in 38 and 34 patients, respectively. In groups I and II, the CABG was elective in 47 (98%) and in 45 patients (90%); the off-pump surgery was performed in 27 (56%) and 12 (24%) patients, respectively. The total duration of bypass was 37 ± 6 minutes and 44 ± 5 minutes; the duration of aortic clamp was 26 ± 4 and 29 ± 7 minutes, respectively, in groups I and II. Posoperative complication rates were: infection in 12 (25%), bleeding in eight (17%), acute renal insufficiency in eight (17%), prolonged air escape in five (10%), and prolonged entubation in 17 (35%) patients in group I and atrial fibrillation in 11 (22%) patients in group II. Mortality rates in both groups were two (4%). Conclusion: CABG in patients with comorbid malignancy is as safe as the other patients. In patients with full remission of malignancy, the surgeons should be encouraged about the safety of CABG. (J Card Surg 2009;24:151-155) © 2009 Wiley Periodicals, Inc.
