Abstract:
Esophageal cancer is thought to be the most malignant neoplasm due to its biological aggressiveness. The most effective treatment modality for esophageal cancer, particularly T4 esophageal cancer, is chemoradiotherapy (CRT). Some T4 patients show long-term survival after receiving CRT, suggesting that even T4 esophageal cancer can be cured with this modality. Although surgery is performed after CRT in some T4 cases, its prognostic benefit is controversial. In this paper, we review the status of CRT and conversion surgery as well as the development of new regimens and discuss the future prospects of CRT in the treatment of T4 esophageal cancer in Japan.
