description | PURPOSE: To evaluate and analyze the efficacy and prognostic factors of intensity-modulated radiotherapy in 250 patients with cervical and upper esophageal carcinoma. PATIENTS AND METHODS: From September 2009 to September 2016, we retrospectively analyzed 250 patients with cervical and upper esophageal carcinoma treated with intensity-modulated radiotherapy (IMRT). In our study, all patients received IMRT, 54 patients with cervical esophageal carcinoma and 196 patients with upper esophageal carcinoma. Treatment response, survival status and failure modes of treatment were observed, and prognostic factors were analyzed. RESULTS: The median survival time was 22.60 months and 3-year survival rate was 42%. The median progress-free survival time was 14.52 months and 3-year progress-free survival rate was 29.3%. The median survival time and the median progress-free survival time for cervical esophageal carcinoma were 20.40 and 15.15 months, respectively. The median survival time and the median progress-free survival time for upper esophageal carcinoma were 25.80 and 14.52 months, respectively (P>0.05). The significant clinical factors associated with survival were patient age, radiotherapy dose and T stages (P<0.05). Radiotherapy dose and concurrent chemoradiotherapy were the significant clinical factors related to progression-free survival (P<0.05). Recurrence appeared in 55.2% patients, including local recurrence in 22.40%, region relapse in 10.40% and distant metastasis in 12.40%. Local recurrence was the main mode of treatment failure. During treatment, the main treatment-related acute toxicity was leukocytopenia and anemia. CONCLUSION: In this study, IMRT demonstrated clinical benefit and well-tolerated toxicity in patients with cervical and upper esophageal carcinoma. |
