“…In our study, two cases of simultaneous CABG and tumor surgery, including one case each of colon cancer and malignant thymoma, were performed without complications related to perioperative incisional infection, severe bleeding, or a lung infection. Patients with tumors undergoing staged CABG and tumor surgery had the advantage of a low incidence of adverse cardiovascular events, the interval between the two procedures ranged from 5 to 60 days, and it was also considered that there was no significant correlation between the recurrence or metastasis of the tumor and no correlation to the time between staged procedures [23]. In this study, four patients underwent coronary artery bypass surgery (esophageal cancer, bladder cancer, lung cancer, and rectal cancer) and staged radical tumor surgery, with an interval of approximately 1-3 months between the two procedures, and there were no in-hospital deaths, and no tumor metastasis or recurrence was found during the follow-up periods, and no cardiovascular adverse events such as angina pectoris, acute myocardial infarction, ventricular arrhythmia, sudden cardiac death or heart failure occurred.…”
