Background The efficacy of intensity-modulated radiotherapy (IMRT) for cervical esophageal cancer has not been determined. Methods Eighty patients with cervical esophageal cancer treated with definitive chemoradiotherapy from 2002 to 2014 were analyzed. Overall survival (OS), failure patterns, and toxicity incidence were compared between the IMRT (N = 32) and 3D conformal radiotherapy (RT; N = 48) groups. Results The median follow-up was 35.9 months. The 3-year OS of the IMRT, 3D conformal RT, and total groups was 81.6%, 57.2%, and 66.6%, respectively. Pulmonary toxicity was not observed with IMRT. Six of 62 cases (9.6%) with nodal involvement developed upper cervical node recurrence outside the prophylactic region. Ten patients in the IMRT group were salvaged, and 60% survived without recurrence; 20% of the 3D conformal RT group was salvaged. Conclusion The IMRT group was comparable with 3D conformal RT group, with a better salvage rate. We recommend extended cervical irradiation for nodal involvement. [ABSTRACT FROM AUTHOR] |
