本文报道我院应用激光血卟啉衍生物(HPD)诊活体表恶性肿瘤6例(18个瘤灶)的方法和结果。5例获得了较满意的近期效疗,1例因激光照相时局部疼痛而中止治疗。本组病例按18个瘤灶计算,瘤体完全消失14个,部分消失3个,无反应1个。本法对癌肿组织选择性高,但对癌肿附近近正常组织无明显损伤,在治疗过程中未见有全身反应,而且操作简便、安全,说明本疗法是治疗体表恶性肿瘤一种很有前途的疗法。本文并对激光HPD诊治恶性肿瘤的机理、诊断和治疗用光源等有关问题进行了讨论。
In this paper, we report the method and results of 6 cases (18 tumors) of malignant surface tumors treated with laser hematoporphyrin derivative (HPD) in our hospital. Five patients received satisfactory near-term efficacy and one patient discontinued treatment due to local pain during laser photography. In this group of cases, 18 tumor foci were counted, 14 disappeared completely, 3 disappeared partially, and 1 did not respond. This method has high selectivity for cancerous tissue, but it has no obvious damage to the near normal tissues near the cancer. There is no systemic reaction during the course of treatment, and the operation is simple and safe. This shows that this therapy is a very good treatment for malignant tumors of the body surface. Promising therapies. This article discusses the issues related to the mechanism of laser HPD diagnosis and treatment of malignant tumors, and the diagnosis and treatment of light sources.
