Abstract 4099

Background

The aim of this study was to analyze the safety and effectiveness of different preoperative preparation time in the neoadjuvant chemotherapy (SOX) regimen in patients with advanced gastric cancer.

Methods

From June 1 2010 to June 1 2017, 120 patients aged from 25 to 80 with clinical stage IIA-IIIC gastric cancer received neoadjuvant chemotherapy with S-1 and oxaliplatin and radical gastrectomy in Chinese PLA General Hospital. They were eligible for inclusion and they were randomly assigned to either the 3-weeks group, which received radical gastrectomy 3 weeks after neoadjuvant chemotherapy (n = 60), or the 5-weeks group, which received radical gastrectomy 5 weeks after neoadjuvant chemotherapy (n = 60). We compared short-term surgical outcomes between the two groups.

Results

There were no significant differences between the two groups regarding the clinical pathological characteristics. However, the 5-weeks group had less intraoperative blood loss (229 ml vs 240 ml, P = 0.031) and less Clavien-Dindo grade II to IV complications (P = 0.006) than the 3-weeks group. Baseline clinicopathologic characteristics, and short-term outcomes of the patients treated in the two groups were similar.

Conclusions

Patients with advanced gastric cancer undergoing advanced neoadjuvant chemotherapy after neoadjuvant chemotherapy require a certain amount of time to adjust and prepare for gastrectomy. Considering the general condition of the patients, the preoperative interval can be shortened and the efficacy can be improved.
