Nimotuzumab is an anti-EGFR monoclonal antibody which has been widely used in cancer treatment. However, the safety and efficacy of nimotuzumab combined with chemotherapy in locally advanced or metastatic esophageal cancer patients remain unclear.
MATERIAL AND METHODS: To address this open question, we collected a total data of 21 patients diagnosed with locally advanced or metastatic esophageal cancer between 2012 and 2016 in a, retrospective study. The patient characteristics, efficacy safety, and toxicity were evaluated in our study.
RESULTS: We observed 1 (4.8%) patient with complete response, 7 (33.3%) patients with partial response, 9 (42.9%) patients with stable response and 4 (19%) patients with progression response. The objective response rate was 38.1% and disease control rate was 81%. The mean progression-free-survival was 7 months and the 18-month overall survival (OS) was 10%. The incidence rate of anemia and leukopenia was 71.4% and 81%, respectively. Two patients showed the serious adverse event of myelosuppression, with nausea, fatigue, and anorexia. No long-term drug-related toxicity was observed during the follow-up.
CONCLUSIONS: Nimotuzumab combined with chemotherapy can achieve promising clinical outcomes in locally advanced or metastatic esophageal cancer, without accumulation of toxicity and was well-tolerated.
