Preoperative Cardiac Risk Assessment and Surgical Outcomes of Patients with Gastric Cancer
To evaluate the incidence of major adverse cardiac events (MACE) and long-term surgical outcomes after gastrectomy for gastric cancer using the revised cardiac risk index (RCRI), which is based on preoperative insulin use, serum creatinine >2.0 mg/dL, and history of ischemic or congestive heart failure or cerebrovascular disease.
We allocated 1000 patients who underwent elective gastrectomy to three groups with ≥3 (group A, n = 32), 2 (group B, n = 142), or 1 (group C, n = 826) of these factors and compared surgical complications and prognoses.
Groups A and B had older patients than group C. Group B had more male patients than groups A and C. Tumor staging and gastrectomy type were similar among all groups. D1 lymph node dissection was more frequent in group A than in groups B or C. The incidence of MACE in groups A, B, and C was 25.0, 9.9, and 1.1 %, respectively. RCRI was associated with MACE. Furthermore, the incidence of pneumonia and in-hospital mortality was associated with RCRI risk factors. However, the incidence of anastomotic leakage, intra-abdominal abscess, wound infection, and pancreas-related infection were similar among the groups. The 5-year overall survival rates of the three groups were 44.3, 65.2, and 80.8 %, which were significantly different.
Patients with RCRI factors have an increased risk of MACE, pneumonia, and higher mortality after gastrectomy; thus, careful patient selection and meticulous perioperative care are crucial for successful gastrectomy.
