ABSTRACT
Objective:
To investigate the efficacy and adverse reactions of simultaneous integrated boost intensity-modulated radiotherapy (SIB-IMRT) combined with chemotherapy in the treatment of superior mediastinal lymph node metastasis after esophageal cancer surgery.Methods:
The clinical data of 72 patients with concurrent chemoradiotherapy for superior mediastinal lymph node metastasis after esophageal cancer surgery in Tai'an Cancer Prevention and Treatment Hospital from January 2019 to May 2021 were retrospectively analyzed, and they were divided into intensity-modulated radiotherapy (IMRT) group (36 cases) and SIB-IMRT group (36 cases) according to different radiotherapy methods. The short-term efficacy, long-term survival rate and adverse reactions of the two groups were compared.Results:
The response rate in the IMRT group was 66.7% (24/36), the response rate in the SIB-IMRT group was 86.1% (31/36), and the difference between the two groups was statistically significant ( χ2 = 3.77, P = 0.047). The 1-, 2- and 3-year overall survival rates in the IMRT group were 75.0%, 44.4% and 27.8%, and the 1-, 2- and 3-year overall survival rates in the SIB-IMRT group were 83.3%, 52.8% and 33.3%; the difference in the overall survival between the two groups was not statistically significant ( χ2 = 0.70, P = 0.401). There were statistical differences in the incidence of leukopenia, radiation esophagitis and radiation pleural gastritis between the two groups (all P < 0.05). There were no statistical differences in the incidence of radiation pneumonia and gastrointestinal reactions between the two groups (both P > 0.05).Conclusions:
SIB-IMRT combined with chemotherapy in patients with superior mediastinal lymph node metastasis after esophageal cancer surgery has good local control rate and mild adverse reactions.
