Safety of Laparoscopic Oncologic Resection in Elderly Patients with Colorectal Cancer: A Multicenter Retrospective Study Based on Perioperative Short-Term Outcomes

摘要

Objectives: Over the last century, unthinkable goals have been achieved in health care and medical sciences, leading to longer life expectancy. Although cancer affects all ages, it disproportionately targets older individuals. Thus, surgical oncologists are confronted with increasing numbers of older patients presenting with multiple chronic conditions. We intended to investigate the safety of oncologic resection in older patients with colorectal cancer (CRC) based on perioperative outcomes. Materials and Methods: We retrospectively collected and analyzed data from older patients (>85 years) who underwent curative resection for stage II or III CRC between January 2007 and August 2017 at four hospitals (St. Vincent's Hospital, Incheon St. Mary's Hospital, Seoul St. Mary's Hospital, and Yeouido St. Mary's Hospital). Results: A total of 140 patients were enrolled in this study. The mean age was 87.1, the mean stay in the intensive care unit after surgery was 1.6 +/- 3.8 days, and the mean postoperative hospital stay was 10.5 +/- 3.8 days, D3 lymph node dissection was performed in 67.0% of patients, and D2 lymph node dissection was performed in 33.0%. Postoperative complications occurred in 38 patients (27.9%). In the univariate analysis, the risk factors for postoperative complications were the omission of mechanical bowel preparation (P = .039) and open surgery (P = .031). Conclusions: Oncologic resection in selected older patients with CRC might be a relatively safe treatment option. In particular, a laparoscopic approach might be a safer surgical method than open surgery in older patients with CRC.
