Immediate Results of Concurrent Chemoradiotherapy with Inoperable Esophageal Squamous Cell Carcinoma
Background: The incidence of esophageal cancer is increasing. In this connection, the search for the most effective methods of treating this disease continues. In most patients, esophageal cancer is diagnosed at III- IV stages of the disease. Currently, the standard of treatment for inoperable patients is chemo radiotherapy. Brachytherapy is one of the perspective methods of radiation therapy. Using of brachytherapy in the complex treatment of patients with esophageal cancer makes possible to increase the radiation dose without increasing the risk of complications after treatment.Methods: The study included 20 patients with inoperable esophageal cancer (most of them with III stages, 60 %). The age of the patients is from 51 to 89 years, ECOG performance status ½ (25 %/75 %), dysphagia score 1/2/3-4 (25 %,50 %, 25 %). All patients were diagnosed with esophageal squamous cell carcinoma. Most patients were with tumor in the middle third of the esophagus (70 %). The greatest length of the tumor was 10 cm. On the first stage of treatment patients underwent external-beam radiation therapy 46 Gy in 2 Gy fractions with simultaneous chemotherapy. After that, brachytherapy was performed (single dose of 5 Gy, 2 fractions with an interval of 6-7 days, 62,8 Gy (EQD2, α/β = 10 Gy).Results: Patients received therapy support for cardiovascular and lung diseases and nutritional support before, during and following chemoradiotherapy. There were no patients with hematological toxicity grade 3-4. Esophagitis grade 2 was noted in 40 % of patients, grade 1 in 60 % of patients. Esophagitis resolved on its own 2 weeks after completion of therapy. Complete tumor regression was observed in 10 % of patients, partial regression in 80 % of patients, stabilization of tumor process was observed in 10 % of patients. All patients have a poor QOL due to physical and psychological disorders. The general health situation and physical function after 3 months of treatment was improved compared to the prior to treatment period.
