Laparoscopic Surgery for Elderly Colorectal Cancer Patients With High American Society of Anesthesiologists Scores.

Anticancer Research 2023 December
BACKGROUND/AIM: To evaluate the safety of colorectomy in elderly colorectal cancer patients with high American Society of Anesthesiologists (ASA) scores compared to those with low scores.

PATIENTS AND METHODS: Two hundred patients with stage I-IV colorectal cancer aged ≥80 years were retrospectively analyzed. Short- and long-term outcomes were compared between 136 patients with ASA scores ≤2 (low ASA group) and 64 patients with scores ≥3 (high ASA group).

RESULTS: The incidence of postoperative complications, duration of postoperative hospital stay, and 5-year overall and cancer-specific survival rates did not differ significantly between the groups. Laparoscopic surgery was significantly associated with a lower incidence of postoperative complications than open surgery in the high ASA score group (p=0.041), whereas no difference was observed in the low ASA score group (p=0.639). In the high ASA group, open surgery (p=0.024) and higher body mass index (p=0.040) were independent risk factors for postoperative complications.

CONCLUSION: Colorectal cancer resection can be safely performed in elderly patients with high ASA scores. Moreover, laparoscopic surgery may have a stronger contribution to the reduction of postoperative complications in elderly patients with colorectal cancer with high ASA scores than in those with low ASA scores.
