[Case of Long-Term Survival after Definitive Chemoradiotherapy for Unresectable Locally Advanced Esophageal Squamous Cell Carcinoma].

67-year-old woman underwent definitive chemoradiotherapy( dCRT) with cisplatin( CDDP) and 5-fluorouraci(l 5-FU)(FP) for locally advanced unresectable squamous cell carcinoma of the thoracic esophagus. During treatment, the patient developed grade 3 pharyngitis and esophagitis as adverse events. She was administered maintenance chemotherapy with 2 courses of FP and achieved complete response. Currently, she experiences esophageal stenosis; however, she remains alive and recurrence-free 9 years after initial treatment. While dCRT is effective for locally advanced esophageal cancer, its adverse effects may persist. Herein, we report our case and have included relevant literature considerations.
