Surgical resection following combination chemotherapy with oral S-1 and biweekly docetaxel in a patient with advanced gastric cancer and a prior coronary artery bypass graft with the right gastroepiploic artery: Report of a case

Cardiothoracic surgeons commonly use the internal thoracic artery (ITA) and the right gastroepiploic artery (RGEA) when performing a coronary artery bypass graft (CABG). Although the development of CABG surgery has enabled long-term survival in patients with coronary artery disease, malignant diseases are more common in older patients. We present the case of a 75-year-old man who had previously undergone CABG with the RGEA and had later developed advanced gastric cancer. We treated this patient with two courses of combination chemotherapy using S-1 and docetaxel as induction therapy, followed by successful tumor resection. Therefore, neoadjuvant chemotherapy was effective for preserving the CABG with the RGEA in a patient with advanced gastric cancer.
