A Case of Spontaneous Regression of Advanced Gastric Cancer

ABSTRACT

An 84 yr-old male with a history of nausea and vomiting for 3 weeks was admitted to our hospital. Esopahgogastroduodenoscopy showed the diffuse infiltrative type of gastric cancer encircling from the cardia to the lower body. On abdominal computerized tomography, the gastric wall was diffusely thickened with overlying mucosal enhancement without lymph node involvement. Histologic examination revealed poorly differentiated adenocarcinoma. So surgical resection was planned. However, patient refused all medical care, and then he was discharged. He lived without any medical support and then he revisited our hospital and showed relieved symptoms on the follow-up exam. On esophagogastroduodenoscopy, the gastric mucosa of the body looked normal without any dysplastic change. Abdominal CT revealed a decreased thickening of the gastric wall of the body. The histology from the endoscopic forceps biopsy showed no evidence of malignancy. The patient is alive without any sign of tumor recurrence after 14 months.
