自1982年全国开展血卟啉(光卟啉)与激光相结合诊治恶性肿瘤以来,各地研制成功不少血卟啉衍生物,为了对国产血卟啉衍生物作出科学的评价,我们对其疗效与毒性作了考查,并与美国第二代血卟啉衍生物——Photofrin Ⅱ进行了比较。现将评价疗效及毒性的二项简便方法和结果报告如下: Since 1982, hematoporphyrin (porphyrin) combined with laser diagnosis and treatment of malignant tumors around the successful development of many hematoporphyrin derivatives, in order to make a scientific evaluation of domestic hematoporphyrin derivatives, we have its efficacy And toxicity were examined, and with the United States second generation hematoporphyrin derivative Photofrin Ⅱ were compared. Two simple methods and results to evaluate efficacy and toxicity are now reported as follows:
