Der Klatskin-Tumor: Moderne radiologische Diagnostik, Interventions- und Therapiemöglichkeiten

The multimodal treatment of central and peripheral cholangiocarcinoma - analysis based on a single center experience

The hilar and intrahepatic location represents the most frequent positioning of cholangiocarcinoma. Late diagnosis, tumour resection - as the sole method of radical treatment require a multimodal approach of this form of malignancy.

Effect of 103Pd radioactive stent on caspase-9, cholangiocarcinoma cell growth and its radiosensitivity

BACKGROUND

To investigate the effect of (103)Pd radioactive stent on Caspase-9, cholangiocarcinoma cell growth and its radiosensitivity.

METHODS

Cholangiocarcinoma was treated with (103)Pd radioactive stent at different period. Radiosensitivity of the cells was detected by methyl thiazolyl tetrazolium (MTT) method. Apoptosis of cholangiocarcinoma cells was detected by immunohistochemistry and electron microscope. The activity of Caspase-9 was detected by non-radioimmunoprecipitation, while its protein expression was detected by Western blot.

RESULTS

(103)Pd radioactive stent had significant inhibitive effect on cholangiocarcinoma cells and it could induce apoptosis. After treatment by (103)Pd radioactive stent for 10 days, the activity of Caspase-9 was gradually enhanced, which was markedly decreased in common stent group. Cholangiocarcinoma cells had relatively high sensitivity to (103)Pd radiation.

CONCLUSION

(103)Pd radioactive stent can activate caspase-9 gene to induce apoptosis of cholangiocarcinoma cell, inhibit its growth and enhance its radiosensitivity.
