AbstractObjective To evaluated the efficacy of biomarker-guided concurrent chemoradiotherapy in unrescetable esophageal squamous cell carcinoma patients. Methods 54 cases of unrescetable esophageal squamous cell carcinoma were enrolled in the prospective non-randomized clinical study and divided into study group and control group. All cases were treated with concurrent chemoraditherapy. Intensity-modulated radiation therapy was used with a dose of 60-66 Gy. Chemotherapy was perfromed on day 1 and d29.In the study group the selection of the chemotherapy drug was based on the excision repair cross-complementation 1(ERCC1),thymidylate synthetase (TYMS),ribonucleotide reductase M1(RRM1),and the β-tubulin isotype Ⅲ(TUBB3) mRNA expression levels. In the control group,the regiment for chemotherapy was Cisplatin plus Fluorouracil. TheObjective response rate and overall survival (OS) were calculated using Kaplan-meier method and log-rank test was used for between-group comparison. The survival rate was calculated using Kaplan-Meier method and analyzed using log-rank method,other comparison was performed by χ2 test. Results The follow-up rate was 100% in the study group and 96% in the controll group. The Objective response rate of the study group and the control group were 85% and 86(P=0.483),respectively. The median survival time (MST) in the study group was 35.5 months and that in the control group was 25.8 months. The 1-,2-,and 3-year OS rates of the study group and the control group were 84%,68%,46% and 71%,59%,28% respectively (P=0.047).No significant differences were observed in the incidence of side-effects in the two groups. Conclusions Selecting the chemotherapy drug according to biomarker,combined with radiation therapy,could improve survival.in unrescetable esophageal squamous cell carcinoma. The value needs further investigation.
