激光是一种光电子学新技术,我们应用CO_2激光对实验动物移植性肿瘤作实验治疗观察,同时用激光合并化疗、化疗、单纯激光对移植性肿瘤作了治疗效果比较。本实验结果表明CO_2激光对不同的移植性肿瘤有一定效果,小鼠黑色素瘤经激光照射后肿瘤消失率为80%,小鼠S_(180)肉瘤肿瘤消失率为80%,大白鼠瓦克癌肿瘤消失率为47.6%。同时激光合并化疗比单纯激光疗效有显著提高。大白鼠瓦克癌经激光照射,同时给予化疗,肿瘤消失率为77.8%(X~2=6.210,P<0.05),而单纯激光治疗,肿瘤消失率为47.6%,表明激光合并化疗,明显地增加其对瘤体的破坏作用,使疗效显著提高。激光是一种光电子学新技术,1963年Mcguff首先用红宝石激光照射移植在田鼠身上的Pitt_4黑瘤,使肿瘤消失,其后Goldman用二氧化碳激光在临床上治疗二例恶性肿瘤病人,一例是基底细胞上皮瘤,另一例是分叶的血管肉瘤均获得成功,分别随访八个月和九个月未见复发。随着我国社会主义建设事业的飞跃发展,激光技术在临床医学上的应用范围日益扩大。我们应用CO_2激光对不同的移植性肿瘤作实验治疗观察,同时用激光合并化疗,化疗、单纯激光对移植性肿瘤作了治疗效果比较,为了这目的进行实验研究,从结果表明CO_2激光对不同的移植性肿瘤有一定效果,同时激光合并化疗比单纯激光疗效有显著提高,现将实验结果报导如下,供临床应用激光治疗肿瘤提供参考。
Laser is a new technology of optoelectronics. We used CO 2 laser to observe the transplanted tumors of experimental animals. At the same time, we compared the therapeutic effects of laser with chemotherapy, chemotherapy, and laser alone on transplanted tumors. The results of this experiment show that the CO 2 laser has a certain effect on different transplanted tumors. The tumor disappearance rate of mouse melanoma after laser irradiation is 80%, the tumor disappearance rate of mouse S 180 sarcoma is 80%, and rat WACKER cancer The tumor disappearance rate was 47.6%. At the same time, laser combined chemotherapy has a significant increase in efficacy compared with laser alone. In rats WACKER treated with laser irradiation and chemotherapy, the tumor disappearance rate was 77.8% (X~2=6.210, P<0.05), while the laser treatment alone, the tumor disappearance rate was 47.6%, indicating laser combined chemotherapy, obviously Increase its destruction of the tumor, so that significantly improved efficacy. Laser is a new technology of optoelectronics. In 1963, Mcguff first used a ruby laser to irradiate Pitt_4 melanoma implanted in a voles. The tumor disappeared. Later, Goldman used a CO2 laser to treat two patients with malignant tumors. One case was a basal cell. Epithelial neoplasia, another case of segmental hemangiosarcoma, was successful, with no recurrence after follow-up of eight months and nine months, respectively. With the rapid development of China’s socialist construction, the scope of application of laser technology in clinical medicine is expanding. We used CO 2 laser to observe different transplanted tumors for experimental treatment. At the same time, we used laser combined with chemotherapy, chemotherapy, and simple laser to compare the therapeutic effects of transplanted tumors. We conducted an experimental study for this purpose. The results showed that CO 2 lasers were different. The transplanted tumor has a certain effect. At the same time, the laser combined chemotherapy has a significant improvement over the laser therapeutic effect. Now the experimental results are reported as follows, for clinical application of laser treatment for tumors to provide a reference.
