Yoğunluk Ayarlı veya 3 Boyutlu Konformal Radyasyon Tedavisi Kullanılarak Definitif Kemoradyoterapi İle Tedavi Edilen Servikal Özofagus Kanserinin Sağkalım Sonuçları: Tek Merkez Deneyimi

Abstract

Abstract
 Objective: The aim of this study is to report the survival and treatment results of patients with cervical esophageal cancer treated with definitive chemoradiotherapy, whose incidence is very low in the population and there is not enough information about treatment and toxicity results in the literature. 
 Material and Method: Between 2013 and 2022, 10 patients (six males and four females) with cervical esophageal cancer treated with definitive chemoradiotherapy were included. Among these patients, seven had stage II disease, one stage III, and 2 stage IVA. All patients received radiotherapy at a median dose of 50.4 Gy and concurrent weekly chemotherapy.
 Results: The median follow-up period was 18 months. The two-year and 5-year overall survival rates were 42.2% and 21.1%, respectively. The two-year and 5-year disease-free survival rates were 45.7% and 22.9%, respectively. Disease progression was noted in 3 out of 10 patients (30%). Three patients were still alive during analyze. Percutaneous enteral gastrostomy was performed in 3 of 10 patients. These requirement occured in 1 due to local progression, and in the remaining 2 patients due to the side effect of RT. 
 Conclusions: Overall survival rates were low, as similar findings appear in the literature. It was remarkable that the need for a percutaneous enteral gastrostomy was not observed in the IMRT group. All patients with complete remission were in stage 2.
