Objective : To investigate the therapeutic effects of Hang-Am-Dan(HAD) on gallbladder cancer patients. Method : We prescribed HAD three times a day(3,000-6,000 mg/day) during a treatment period of 8 and 34 months respectively. Computed tomography(CT) was taken to evaluate the therapeutic efficacy. Results : Two patients diagnosed with gallbladder cancer were recommended to go through chemotherapy. However, they refused the standard regimen due to their old age and the fear of side effects, and chose to go with Oriental medicine treatments instead. The patients were treated for 8 and 34 months respectively. Each patient showed stable disease(SD) state during the treatment period. Conclusion : According to these cases, it could be concluded that HAD may offer potential benefits in treating gallbladder cancer patients.
