Introduction:

Oncological management in addition to surgery in patients with gastric cancer remains a matter of debate. We conducted a retrospective longitudinal study to compare the prognosis and complications between perioperative chemotherapy and adjuvant chemotherapy to identify the best treatment scheme.

Materials and methods:

A longitudinal, retrospective historical cohort study was carried out that included all patients who received one of the two treatment schemes. The main objectives were to evaluate overall survival and perioperative complications (fistula, bleeding, death and toxicity) in each group.

Results:

168 patients met the inclusion criteria. Compared with the adjuvant chemotherapy group, the perioperative chemotherapy group had greater survival at 2 and 5 years (80.1% vs. 61.2%, 69.8% vs. 43.6% p=0.003). There was no statistically significant difference in the rate of perioperative complications between the two groups (4.11% vs. 10.64%, p = 0.151). There was an increase in the transfusion requirement in the perioperative chemotherapy group.

Discussion:

Perioperative chemotherapy increases the long-term survival of patients with locally advanced gastric cancer, without a significant increase in the rate of perioperative complications. There is an increase in the transfusion requirement of the perioperative chemotherapy group without this worsening the prognosis of the patients.
