A Case of Lymph Node Metastasis of Intrahepatic Bile Duct Cancer Successfully Treated Using Multidisciplinary Therapy
Abstract
We report a case of lymph node metastasis of intrahepatic bile duct cancer that was successfully treated using chemotherapy and radiation therapy.A man in his 70s underwent hepatic resection for intrahepatic bile duct cancer, and abdominal CT 1 year 8 months after surgery revealed lymph node swelling(25mm in diameter)along the common hepatic artery.He was diagnosed with lymph node metastasis and began to receive chemotherapy.We administered gemcitabine(GEM), cisplatin, and S-1 for 6 months, and GEM and S-1 for 1 year 4 further months as combination therapy.One year 10 months after the start of chemotherapy, the size of the lymph node decreased to 13 mm.However, as FDG uptake was seen on FDG-PET, radiation targeted to the lymph node was applied(50 Gy/25 Fr).After completion of radiation therapy, the lymph node has not regrown even in the absence of treatment, and the patient survives 6 years after the primary operation(4 years 4 months since the start of chemotherapy for recurrence).This case suggested that multidisciplinary therapy might be useful for lymph node metastasis of intrahepatic bile duct cancer.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
