[A Case of Conversion Surgery Following Chemotherapy in Initially Unresectable Locally Advanced Gallbladder...

A 47-year-old woman who had unresectable locally advanced gallbladder cancer(GBC)accompanied with liverinvasion, duodenum invasion, transverse colon invasion, and surrounding lymphatic metastasis received 5 courses of chemotherapy with gemcitabine plus cisplatin. Afterthe chemotherapy, imaging showed down-staging of the GBC, indicating tumor shrinkage. The initial laparoscopic examination revealed no peritoneal seeding or distant metastasis. Subsequently, we performed cholecystectomy with a partial hepatectomy at the gallbladder bed. Malignant findings were not observed in the histopathological examination and the pathological diagnosis was CR with pT0N0M0, Stage 0. The patient was discharged on day 11 after the operation. There has been no recurrence at 14 months after surgery. Although the prognosis of advanced GBC with local invasion is generally poor, chemotherapy might be an effective treatment for patients with initially unresectable locally advanced gallbladder carcinoma.
