ABSTRACT

Objective:

To investigate the efficacy and safety of DOS regimen in adjuvant chemotherapy after D2 radical resection for advanced gastric adenocarcinoma.

Methods:

The clinical data of 130 patients who received adjuvant chemotherapy after D2 radical resection for advanced gastric adenocarcinoma in Jincheng People's Hospital from January 2017 to January 2019 were retrospectively analyzed. According to treatment regimens, the patients were divided into DOS regimen chemotherapy group (DOS group, 63 cases) and SOX (oxaliplatin, S-1) regimen chemotherapy group (SOX group, 67 cases). The short-term efficacy and adverse reactions of the two groups were compared.

Results:

Due to the irregular treatment time, 2 cases in each group were removed. Finally, there were 61 cases in DOS group and 65 cases in SOX group. The 1-, 2- and 3-year disease-free survival (DFS) rates of the DOS group were 80.33%, 73.77% and 62.30%, and the DFS rates of the SOX group were 73.85%, 55.38% and 41.54%. The difference in DFS between the two groups was statistically significant ( χ2 = 5.43, P = 0.022). The 1-, 2- and 3-year overall survival (OS) rates of the DOS group were 93.44%, 80.33% and 70.50%, and the OS rates of the SOX group were 96.92%, 73.85% and 52.31%. The difference in OS between the two groups was statistically significant ( χ2 = 4.38, P = 0.045). There were no statistical differences in the incidence rates of grade Ⅰ-Ⅱ nausea, vomiting, diarrhea, bone marrow suppression and fatigue between the two groups (all P > 0.05). There were no statistical differences in the incidence rates of grade Ⅲ-Ⅳ nausea, vomiting and fatigue (both P > 0.05), but there were statistical significances in the incidence rates of grade Ⅲ-Ⅳ diarrhea and bone marrow suppression (both P < 0.05).

Conclusions:

Adjuvant DOS regimen in the treatment of advanced gastric adenocarcinoma after D2 radical resection has good curative efficacy and can improve the survival of patients, and the adverse reactions can be tolerated.
