Partial or complete spontaneous regression (SR) of cancer is unusual, particularly in patients with oesophageal cancer. This case report describes a patient with biopsy-proven squamous cell carcinoma of the oesophagus which spontaneously regressed without any treatment. Regression of the primary tumour was confirmed on histological examination of the resected specimen. The process of SR remains an enigma, but potential mechanisms are considered.
癌症的部分或完全自发消退(SR)是不常见的,特别是在食管癌患者中。本病例报告描述了一例经活检证实的食管鳞状细胞癌患者,未经任何治疗即自发消退。原发性肿瘤的消退在切除标本的组织学检查中得到证实。SR 的发生机制仍然是一个谜,但考虑了一些潜在的机制。
