在肝、胆道、胰癌根治治疗中,现在首推外科手术;放疗仅居辅助治疗的位置。肝癌的放疗: 进行性肝癌别无他法治疗时可试行放疗。但其有效性至今未能通过统计分析得出结论。以前曾报告一次大剂量照射,最近盛行进行性肝癌在导管栓塞治疗基础上予以放疗。胆道、胰癌放疗的意义: 日本统计1975年胰癌1819例的切除率仅为18.3%。胆道癌切除率仅14.3～40%。进行放疗的病例几乎都是不能切除的病例,治疗目的是延长生命、减轻症状。以往世界文献记载胰癌五年生存仅6例(0.3%),最近世界61家报告五年生存率0.4%。放疗是否有意义,就看能否使症状减轻或消
In the treatment of liver, biliary tract, and pancreatic cancer, surgery is now the first choice; radiotherapy is only the location of adjuvant therapy. Radiotherapy for liver cancer: Radiotherapy can be performed when there is no other treatment for progressive liver cancer. However, its effectiveness has so far failed to reach conclusions through statistical analysis. A large dose of radiation has been previously reported, and recent advancement of progressive liver cancer has been based on catheter embolization therapy. Significance of radiotherapy for biliary tract and pancreatic cancer: In Japan, the resection rate of 1819 cases of pancreatic cancer in 1975 was only 18.3%. Resection rate of biliary cancer is only 14.3 to 40%. Most cases of radiotherapy are cases that cannot be removed. The purpose of treatment is to prolong life and reduce symptoms. In the past world literature, only six cases (0.3%) of pancreatic cancer survived in the past five years, and 61 of the world’s 61 reported five-year survival rates of 0.4%. Does radiotherapy make sense, depends on whether the symptoms can be reduced or eliminated
