Complete response to chemoradiotherapy in a patient with synchronous double gastric and esophageal cancer.

UNLABELLED: A 77-year-old man with early synchronous double primary gastric and esophageal cancer showed complete response (CR) to chemoradiotherapy (CRT) with fluorouracil (5-FU) and cis-diamminedichloroplatinum (CDDP) and 60 Gy total dose of radiation. Gastrointestinal endoscopy had revealed type IIc squamous cell carcinoma in the lower oesophagus and type IIc adenocarcinoma in the mid-stomach region. Synchronous double primary early-stage esophageal and gastric cancer was diagnosed. The patient's age and chronic obstructive pulmonary disease (COPD) contraindicated radical esophageal surgery. Therefore, we decided to first administer CRT with 5-FU and CDDP for the esophageal cancer, and subsequently perform partial gastrectomy for the gastric cancer. After the CRT, neither of the tumors recurred. CR to CRT for the esophageal cancer and CR to chemotherapy for the gastric cancer were achieved.

CONCLUSION

CRT with 5-FU and CDDP can produce CR in cases of early esophageal and gastric cancer.
