Spontaneous regression may occur in malignancies such as hypernephroma, neuroblastoma, malignant melanoma, choriocarcinoma, and bladder tumor, but yet it is extremely rare in carcinoma of the stomach. So far, 19 cases have been reported in the English literature and the mechanisms underlying this intriguing phenomenon remain unknown. A 48-year-old man with histologically-verified advanced gastric carcinoma had received no treatment since its diagnosis. However, gastric carcinoma was no longer detectable by endoscopy and histology after 4 years. Thus, we report a case of spontaneous regression of carcinoma of the stomach with a brief review of relevant literatures.
