Objective: To evaluate the correlative factors of radiation pneumonitis ( RP) induced by radiotherapy for patients with esophageal cancer who were treated with precise radiotherapy.Methods: Clinical data of 110 patients with esophageal cancer who were treated with precise radiotherapy were retrospectively analyzed, with the incidence of radiation pneumonitis observed and correlative factors analyzed.Results: Of the 110 cases, 10 cases got complete remission(CR), accounting for 9.09 %, 66 cases got partial remission (PR), accounting for 60.00 %, 26 cases had no change (NC), accounting for 23.64 %, and 8 cases were in progressive disease ( PD), accounting for 7.27 %. The clinical benefit rate was 69.96 %. Clinical symptoms of RP were found in 22 cases(20 %) of the 110 patients. Single factor analysis showed Karnofsky performance score (KPS), chronic obstructive pulmonary disease(COPD).Conclusion: chemotherapy, the radiation dose for gross tumor volume(GTV), lung V20, mean lung dose (MLD) and target volume of radiation (PTV) were associated with RP.Conclusion: KPS.Conclusion chemotherapy, COPD, lung V20, MLD, PTV, GTV and PTV are main risk factors of RP induced by radiotherapy for patients with esophageal cancer .
