Abstract

Background: Despite the ongoing decrease in the incidence of gastric cancer, this disease is still a major cause of death. It is still debatable whether D2 lymphadenectomy improves survival and whether this procedure should be performed routinely or selectively. Objectives: To compare the pathological and short-term results following radical D2-type gastric resection and lymphadenectomy versus the more limited D1 type resection and lymphadenectomy. Methods: We conducted a retrospective study on 4 years experience treating 164 patients suffering from gastric cancer. We compared the results between the group of patients who underwent a radical D2 type gastric resection and lymphadenectomy (n=100) and those of a relatively small group of patients who intentionally underwent the more limited D1 type (n=34). Results: The overall number of harvested lymph nodes was 9± 4 in the D1 group compared to 30±12 (range 16–69) in the D2 group (P = 0.001). Of the 100 patients undergoing a D2 lymphadenectomy, 57% had positive nodes compared to 38% of the 34 patients in the D1 group (P = 0.045). Conclusions: We showed statistically significant differences between D1 and D2 procedures in the overall number of harvested lymph nodes and the proportion of positive nodes to the overall number. Our results support the fact that D2 resection should be recommended as the standard approach of treatment for gastric cancer patients, ensuring a larger number of retrieved lymph nodes and a comparable rate of complications and mortality.
