Background: The efficacy and safety of treating elderly patients with colorectal cancer (CRC) is of concern. This study aimed to compare the short- and long-term outcomes of elective laparoscopic vs. open surgery to treat CRC in very elderly patients.
Methods: All patients aged >80 years and who had undergone a colectomy for CRC without metastasis between July 2005 and April 2012 were considered for inclusion. Demographic, clinical, operative, and postoperative data, plus overall and disease-free survival rates, were retrospectively collected and compared between two groups of patients that underwent an open procedure (OP group) or laparoscopy (LG).
Results: 123 patients were enrolled (55 OPG, 68 LG). Median age was similar between the groups (84 vs. 83 years, respectively; NS). Duration of surgery was significantly lower in OPG (170 vs. 200min; p=0.030). Overall mortality at 3 months was 8.3%: it tended to be greater in the OPG (16.5% vs. 1.5%, NS). Morbidity was significantly greater in the OPG compared to the LG (52.7% vs. 27.5%; p=0.021), resulting in significantly longer hospital stay (12 vs. 8 days, respectively; p<0.001). Pathological findings were similar between the two groups. Cumulative overall survival rates at 3 and 5 years were significantly greater after laparoscopy (85% and 72%) compared to open surgery (58.2% and 48%, respectively; p<0.001).
Conclusions: Our study suggests that laparoscopy is safe and could increase overall survival compared to open surgery in elderly patients suffering from CRC.
Summary: This retrospective study compared the short- and longer-term outcomes of patients aged >80 years and undergoing elective laparoscopic or open surgery for CRC between 2005 and 2012.
