[Multimodal Therapy for Stage Ⅳ Gallbladder Carcinoma Achieved Long-Term Survival-A Case Report]

A 75-year-old man with a chief complaint of abdominal pain visited our hospital and was diagnosed with Stage Ⅳ gallbladder carcinoma that infiltrated the transverse colon with distant lymph node metastases. He received gemcitabine plus cisplatin chemotherapy, which led the primary lesion to shrink. However, transverse colon obstruction occurred, and semi- urgent right hemicolectomy and extended cholecystectomy were performed. A year and 2 months after first diagnosis, an inferior pancreatic head lymph node swelling was detected. Chemoradiotherapy was performed using S-1, and the lymph node swelling was reduced. Despite continuous S-1 therapy, the lymph node gradually started to swell again, which led to duodenum obstruction by compression. He underwent gastrojejunal bypass; however, his general condition gradually worsened, and he died 2 years and 6 months after the first diagnosis. Even in cases of unresectable gallbladder carcinoma, multimodal therapy, such as surgery, chemoradiotherapy, and palliative gastrointestinal bypass, may archive a long prognosis of 2 years and 6 months.
