Abstract
Background: Gastric cancer is one of the most common malignancies worldwide and in Vietnam. Adjuvant chemotherapy is proved to provide survival benefit for patients in stage II - III. TS-1, which is a new agent, has been more commonly used in Vietnam in this setting.
Methods: 45 gastric cancer patients stage II - III were treated with adjuvant TS-1/SOX regimen at Ho Chi Minh city Oncology Hospital from January 2020 to December 2022. Objectives: To evaluate the safety, tolerability and efficacy of TS-1/SOX regimens in adjuvant therapy for stage II-III gastric cancer in Ho Chi Minh city Oncology Hospital.
Results: 8,9% patients had grade 3 adverse effects (thrombocytopenia, peripheral neuropathy, elevated AST, neutropenia), there were no patients had grade 4 - 5. 35,6% cases delayed chemotherapy due to adverse effects (TS-1 group and SOX group is 20,8% and 52,4%, respectively, p = 0,027). Reduced dosage rate of TS-1 is 25% in TS-1 group and 23,8% in SOX group (p = 0,811). 6-month, 1 - year, 2 - year and 3 - year disease-free survival rates are 100%, 96,1%, 61,5% và 50%, respectively.
Conclusion: Adjuvant chemotherapy with TS-1 - based regimens in stage II - III gastric cancer is safe and well tolerated, with acceptable adverse effects. Due to small sample size, the efficacy of the regimens is needed to be further evaluated in other studies.
