We retrospectively analyzed progression\u2010free survival and overall survival from the initiation of avelumab maintenance therapy. Best overall response was evaluated based on the\n RECIST<\/jats:italic>\n guidelines v1.1. To investigate factors potentially associated with response to avelumab maintenance therapy and overall survival, we conducted an assessment of markers that have been previously reported as prognostic factors, including urothelial carcinoma and other cancers.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n The median overall survival by best overall response of first\u2010line chemotherapy was not reached for complete response, partial response, or 15\u2010month stable disease (\n p<\/jats:italic>\n \u2009=\u20090.27). As for avelumab maintenance therapy, median overall survival by best overall response was not reached for complete response, partial response, and not evaluable; it was 18\u2009months for stable disease and 13\u2009months for progressive disease, with significant differences (\n p<\/jats:italic>\n \u2009=\u20090.04). In multivariable analysis, lactate dehydrogenase level below the upper limit of normal prior to first\u2010line chemotherapy was a significant independent factor in predicting disease control rate (\n p<\/jats:italic>\n \u2009<\u20090.01) and overall survival (\n p<\/jats:italic>\n \u2009=\u20090.04) in avelumab maintenance therapy.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Normal serum lactate dehydrogenase level prior to first\u2010line chemotherapy was a significant predictor of favorable response or prognosis for avelumab maintenance therapy in our
