Background:
Conversion surgery for initially unresectable gallbladder cancer is rarely performed due to the low response rate for systemic chemotherapy, and a pathological complete response is seldom achieved.
Case Presentation:
A 67-year-old woman with jaundice was referred to our hospital and diagnosed with unresectable gallbladder cancer with extra-regional lymph node metastasis after examinations. After biliary decompression, gemcitabine plus cisplatin therapy was started. The tumor marker levels markedly decreased, and imaging studies revealed a reduction in the primary tumor and metastatic lymph nodes. The primary tumor and metastatic lymph node were still shrunk at 4 years after the start of gemcitabine plus cisplatin therapy, so we decided to perform conversion surgery. Gallbladder bed resection and lymph node dissection were performed. The pathological findings of the resected specimen showed only partial fibrosis in the gallbladder wall and no malignant findings in the dissected lymph nodes, indicating a pathological complete response. As of 24 months after the operation, she is alive without recurrence.
Conclusion:
Although there have been only a few reports of conversion surgery for initially unresectable gallbladder cancer, it may be worthwhile to perform chemotherapy with the potential goal of subsequent conversion surgery.
