ARTICLE HIGHLIGHTS
Research background

An increasing number of patients over 85 years old are receiving surgical treatment for gastric cancer (GC) and colorectal cancer (CRC). The number of surgical patients in 2016-2021 was nearly eight times that of patients in 2001-2005 in China. TNM stage and the number of tumor prone sites changed significantly, and the incidence of perioperative complications significantly decreased. Perioperative mortality in the last period was 71.97% lower than it was in the first period. Laparoscopic technology is increasingly used in elderly patients with CRC, but its uptake in the field of GC is slow. In patients with TNM I stage, radical rather than limited lymphadenectomy should be prioritized.

Research motivation

Whether patients over 85 years old with gastrointestinal cancer should undergo surgery remains controversial.

Research objectives

describe the changing trends of characteristics to provide more information to decision makers, and strive to find appropriate surgical plan.

Research methods

Retrospective analysis.

Research results

Only 14 GC patients underwent laparoscopic surgery where 219 CRC patients had this procedure. Cardia and esophagogastric junction cancer increased in GC patients, and the proportion of sigmoid colon cancer decreased in CRC patients. Pulmonary infection gradually became the most common postoperative complication, its incidence in period 4 reached 48.79%. However, the incidence of anastomotic leakage decreased from 26.79% to 9.38% (P < 0.01). Additionally, 30-d mortality significantly decreased from 32.14% to 9.01%. Increases were observed in 5-year OS in GC patients from period 1 to period 4 (18.18% vs 33.32%, respectively) and CRC patients (0 vs 36.32%, respectively). DFS also increased in GC and CRC patients (7.14% vs 27.74% and 0 to 36.03%, respectively). The average survival time of GC patients following radial lymphadenectomy was higher than in patients that underwent limited lymphadenectomy (26 vs 22 mo, respectively), the same was seen in CRC patients (44 vs 33 mo, respectively). This advantage was particularly evident in patients with TNM I, but not in patients with TNM II/III period cancer.

Research conclusions

The safety as well as effectiveness of surgery in ultra-elderly patients is increasing. Radical lymphadenectomy has advantages in patients with TNM I gastrointestinal cancer, but not TNM II/III.

Research perspectives

Gastric cancer, colorectal cancer.
