Abstract

|
The effects of a combination of radiation and aggressive resection on survival, local control and patterns of recurrence were analyzed in 93 consecutive patients with stage Ⅳ(TNM) gallbladder cancer. Operative morbidity and mortality rates were 17.2% and 5.4%, respectively. and adjuvant radiotherapy yielded a significantly higher 5-year survival rate (n=.50; 13.2%) than resection alone (n=43; 4.4%). Significant improvement in long-term survival was exhibited when radiation was used appropriately on patients with microscopic residues or without microscopic residues failed to improve. The local control. rate was significant higher in the adjuvant radiation group than in the group that underwent resection alone(61.7% vs 34.1%). There was no statistical difference in the frequency of distant metastasis between the 2 groups.
