There were 14 patients with a mean age of 65 years (ranged from 47 to 77) who had severe coronary artery disease associated with cancer of other organs. Stomach cancer was in 8 patients, breast cancer in 2, lung cancer in 2, rectum cancer in 1, and esophagus cancer in 1. They were treated with sequence of coronary artery revascularization and surgery for cancer; 9 patients in a two-staged fashion and 5 recent patients in a simultaneous one. In the series of simultaneous procedure, A-C bypass was combined with left ventricular aneurysmectomy in one patient and closure of ASD in another. There was no cardiac complication in both series, but one death from the complication of surgery for cancer in the staged series. Three patients in the staged series could not help being postponed the surgery for cancer by slow recovery from A-C bypass. In conclusion, coronary artery revascularization should anticipate surgery for cancer and simultaneous combined procedures should be chosen when possible.
