Abstract:
Objective To evaluate the effect of radiochemotherapy for unresectable extra-hepatic bile duct cancinoma. Methods Form June 1993 to August 2003, 28 unresectable extra-hepatic bile duct carcinoma treated by radiochemotherapy were analyzed. There were 13 gallbladder carcinoma and 15 bile duct carcinoma. The radiotherapy regimen consisted of conventional radiation therapy group(15 patients,with a median dose of 45Gy, range 30-60Gy) and three-dimensional conformal radiation therapy group(13 patients, with a median dose of 55Gy , range 50-70Gy). Among these patients, 12 patients were treated by radiotherapy alone( RT), 16 patients treated by radiochemotherapy(CRT), with a chemotherapy regimen consisting of 5-Fu 500mg twice weekly or 5-Fu 500mg + DDP 30mg once weekly for 3-6 cycles. Results The CR+PR, SD and PD rate was 14%, 64%, and 21%, respectively. The overall 1-,2-year survival rate was 38% and 15%, with a median survival time of 9.4 months. The 1-year survival of gallbladder cancer and extra-hepatic bile duct cancer was 46% and 27%;of 3DCRT and conventional radiotherapy was 42% and 33%;of those radiation dose less than 50Gy and more than 50Gy was 29% and 45%;of RT alone and radiochemotherapy was 37% and 31%, respectively. There was significance difference in overall survival between those RT dose less than 50Gy and more than 50Gy,(P=0.023). Grade 1-2 and Grade 3 acute gastrointestinal toxicity was 57% and 18%, respectively. Only 25% patients suffered grade 1-2 hematology toxicity. Conclusion Radiochemotherapy shows moderate effect for unresectable extra-hepatic bile duct cancer with acceptable side effects.
