ObjectiveTo explore the safety and feasibility of surgical treatment of simultaneous multiple primary cancer–hepatocellular carcinoma and esophageal squamous cell carcinoma.MethodThe clinical data of one patient with simultaneous multiple primary cancer of hepatocellular carcinoma and esophageal squamous cell carcinoma, who treated in the First Affiliated Hospital of Guangxi Medical University in April 2019 was analyzed retrospectively. ResultsThe patient was diagnosed as hepatocellular carcinoma and esophageal squamous cell carcinoma on admission. After MDT in the hospital, the patient underwent anterior right hepatectomy + cholecystectomy and radical resection of esophageal carcinoma in turn. The procedure of anterior right hepatectomy + cholecystectomy was smooth, the duration of the surgery was 270 min, and the total blood loss was 500 mL, and postoperative pathology showed that hepatocellular carcinoma was in grade Ⅱ. The operation process of radical resection of esophageal cancer was smooth too, the duration of the surgery was 176 min, and the total blood loss was 100 mL, and postoperative pathology showed moderately differentiated squamous cell carcinoma. No related surgical complications occurred after the operation. Thirteen months after the operation of liver cancer and 10 months after the operation of esophageal cancer, the patient was generally in good condition, well wound healing, and no clinical recurrence. The follow-up of the patient was continued.ConclusionIn allusion to simultaneous multiple primary cancers, it is safe and feasible to evaluate the location, pathological stage, and general condition of the patient by combining multi-disciplinary diagnosis and treatment and then performing radical operations in turn.
