Long-term survival of a young woman with peripheral cholangiocarcinoma: a case report

Cholangiocarcinoma is the second most common primary tumor of the liver after hepatocellular carcinoma and accounts for 5 to 25% of primary hepatic malignancies. Patients with intrahepatic or peripheral cholangiocarcinoma (ICC) most often present at an advanced stage leading to a poor prognosis. A review of the literature has produced only 10 patients who have survived over five years. We review the case of a young woman with a large cholangiocarcinoma, who has been disease free for eight years. The patient was treated with a right hepatic lobectomy, and received 4 cycles of 5-fluorouracil and levamisole postoperatively. Known factors associated with longer survival in patients with ICC include lack of evidence of local invasion (i.e. capsular, lymphatic, or vascular), negative margins, mucoblia, and well differentiation of the tumor, as well as the absence of lymph node metastases. Our patient had negative margins and lymph nodes, and showed no local invasion. However, no mucobilia was noted, and the tumor was only moderately differentiated. Young age has never been associated with increased survival. ICC remains a relatively uncommon tumor with an insidious onset and late presentation contributing to poor survival. Surgical resection remains the only therapeutic option. Since few patients are potentially resectable at the time of presentation, efforts at early diagnosis and options for adjuvant therapy are imperative.
