Abstract:
83 Background: As a result of ATTRACTION2, nivolumab was added to the third line treatment in advanced gastric cancer (AGC), but the response rate was about 10%. As there is no predictive biomarker and no comparison with cytotoxic regimen, it is difficult to choice the regimen. Therefore, we examined the treatment outcome of cytotoxic regimen in third line treatment in the real world retrospectively. Methods: We retrospectively evaluated efficacy and safety of cytotoxic regimen as third-line treatment in patients with AGC between July 2015 and December 2017. Results: Among 138 patients received chemotherapy as first line, 29 patients (21%) received third line therapy. The characteristics were as follows; the median age, 70 years old (range 34-80); male/female, 19 (66%)/10 (34%); performance status (PS) 0/1/2, 7/18/4. The overall response rate was 19% and the disease control rate was 38%. The median overall survival (OS) was 6.6 months and the progression free survival was 3.8 months. The most common grade 3/4 hematological toxicities were neutropenia (27%), followed by anemia (27%) and febrile neutropenia (13.7%). Grade 3/4 nonhematological toxicities included anorexia (27.6%), diarrhea (10%), nausea (10%). Conclusions: Cytotoxic regimen as third line showed acceptable activity, but only 21% of patients could received the third line chemotherapy. The further investigation of predictive biomarker of nivolumab is expected.
