食管癌的病程很长,一般来讲,由癌前病变发展为晚期浸润癌,整个病程约需20-30年。在如此长的病程中,似乎我们有足够多的时间着手阻断癌前病变的进展,甚至将其逆转为较轻的病变或正常。这种想法似乎有些天真。一名长期从事肿瘤研究的医务工作者对记者说:“我觉得现在是‘两头凉,中间热’。上头不关心这事儿,下头也不关心,中间是我们搞肿瘤防治的医疗工作者,激动
The course of esophageal cancer is very long, in general, from advanced precancerous lesions to advanced invasive carcinoma, the entire course of about 20-30 years. In such a long course of disease, it seems that we have enough time to start blocking the progression of precancerous lesions, even reversing them to lesser lesions or normal. This idea seems a bit naive. A medical worker who has been engaged in oncology research for a long time told reporters: "I think it is now ’cool on both sides, middle heat’. Do not care about this matter at the top and do not care at the bottom. The middle is the medical worker who works on tumor prevention and treatment, excitement
