We focused on Glasgow Prognostic Score (GPS), which reflects systemic inflammatory and nutritional status as well as disease control by chemotherapy immediately before nivolumab (DCBC). Patients and Methods: AGC patients with measurable lesions who were treated with nivolumab in the third- or later-line were included. DCBC was defined as a best overall response of complete response (CR), partial response, stable disease, or non-CR/non-progressive disease achieved by chemotherapy immediately before nivolumab. Results: Eighty patients were analyzed. Among the various clinical factors, multivariable analysis revealed that a GPS of 2 was significantly associated with a shorter overall survival and DCBC was significantly associated with a longer progression-free survival. Conclusion: We present the potential of GPS and DCBC as efficient biomarkers of nivolumab for AGC, that warrants further evaluation. ER -
