BACKGROUND AND AIM

The combination of photodynamic therapy and biliary stenting seems to be beneficial in the palliative treatment of unresectable cholangiocarcinoma. We aimed to assess the accuracy of photodynamic therapy in a single centre.

METHODS

Fourteen selected patients, with jaundice related to unresectable cholangiocarcinoma, underwent photodynamic therapy and biliary stenting (with or without chemotherapy). Photofrin was injected intravenously (2 mg/kg) 2 days before intraluminal photoactivation. In case of malignant progression, photodynamic therapy was repeated. The outcome parameters were overall survival and quality of life.

RESULTS

There were eight men and six women (median age: 67 [42-81]). Unresectability was related to a low Karnofski index (n = 2), peritoneal carcinomatosis (n = 4), vascular involvement (n = 3), invasion of the hepatoduodenal ligament (n = 2) and an under-sized liver remnant (n = 3). Biliary stenting was efficient (> or = 50% total bilirubin) in 78.5% of cases. Eight patients developed cholangitis. The mean number of photodynamic therapy procedures was two (1-4). Six (43%) patients needed > or = 2 procedures. No severe toxicity was noted. Photodynamic therapy improved the Karnofski index in 64% of cases. Six (42.8%) patients received concomitant chemotherapy (gemcitabine). The median survival time was 13.8 [0.7-29.2] months. The 3-, 6- and 12-month survival rates were 85%, 77% and 77%, respectively.

CONCLUSION

These results confirm the beneficial effect of biliary drainage, photodynamic therapy and chemotherapy for unresectable cholangiocarcinoma in selected patients with jaundice.
