讨论癌治疗进展,就必须看生存率的提高日本癌治疗的平均生存率仅10～20%,仍然较低。但与20年前50%的病例不能治疗,或只作姑息疗法相比,现在的确是在缓慢地进步。当前消极的治疗状况已不存在,不能治疗的病例也已很少。五年生存率已上升到30%左右。用现在水平分析妨碍提高治愈率的原因,可举出下述各因素,连同应采取的对策讨论如下。一、下咽腔是不易患癌的脏器、日本粗略统计,患癌率为0.3/10万人口,因此,关于下咽癌的卫生宣传不够。病人就诊较迟,医师采取的措施也往往缓慢。参看作者所经治的400例患者的病期分类,Ⅰ期不足10%,Ⅲ、Ⅳ期占70%,可以说未见有何进步。 To discuss the progress of cancer treatment, we must look at the increase in survival rate. The average survival rate of cancer treatment in Japan is only 10 to 20%, which is still low. However, compared with palliative care, which is not treatable in 50% of cases 20 years ago, it is indeed slowly progressing. The current negative treatment status is no longer present, and there are few cases that cannot be treated. The five-year survival rate has risen to around 30%. The factors that hinder the improvement of the cure rate with the current level of analysis include the following factors, which are discussed below along with the measures to be taken. First, the lower pharyngeal cavity is an organ that is not susceptible to cancer, and Japan has a rough statistics. The cancer-bearing rate is 0.3 per 100,000. Therefore, there is not enough health promotion about hypopharyngeal cancer. Patient visits are late, and doctors are often slow. Referring to the classification of the disease of 400 patients treated by the authors, stage I was less than 10%, and stage III and IV accounted for 70%. It can be said that no progress has been made.
