回复1楼:18世纪西方就开始尝试用砒霜治癌症了。
这次香港做到存活率97%以上，毫无疑问是科学突破。
没有科学过程，谁都可以用砒霜，顶多算个idea。
计量还得看手抖不抖。

有进步要表扬，但是还不够。中医的低剂量砒霜制剂已经能治病了，上海肿瘤医院里是很普通的药物。如果进一步研究应该向靶药方向前进，砒霜直接送到癌细胞里。显然还没有。

The first reports of the anticancer activity of arsenic trioxide date back to 1878, when a report from Boston City Hospital described Fowler's solution lowering leukocyte levels in the blood of two healthy individuals and one patient.[4][11] Arsenic trioxide continued to be used in the treatment of leukemia until the introduction of radiotherapy. It made a resurgence in the 1930s when the first studies confirmed the high efficacy of arsenic trioxide in treating chronic myelogenous leukemia.[12]
