摘要: 目的 探讨热化疗对颌面部鳞癌细胞热休克蛋白(HSP)70表达的影响。方法 12例鳞癌患者给予每周2 次,5周10次为1个疗程的热化疗处理。12例患者均静脉注射平阳霉素8 mg,43℃微波热疗40 min。于患者治疗 前及治疗5次后取肿瘤组织制作标本。用SP免疫组织化学法观察肿瘤细胞HSP70的表达。结果 热化疗1疗程 结束后12例患者肉眼未见明显包块,免疫组织化学染色提示治疗中癌细胞HSP70表达增多。结论 热化疗可以 明显提高HSP70在肿瘤细胞中的表达,HSP70通过其抗原递呈等系列免疫效应,发挥抗肿瘤作用。

Abstract:

Objective To study the influence of themochemotheraphy on the expression of HSP70 in maxillofacial squamous cell carcinoma.Methods 12 patients were treated with themochemotheraphy twice a week,altogether 10 times.After 8 mg of Pingyangmycin infused, the patients were treated with microwave hyperthermia at 43℃for 40 min.The part of carcinoma tissue was removed with surgical operations at before treatment and aftre five times of treatment. The expression ofHSP70 in tumor cells was determined by SP immunohitochemcial method.Results The expression of HSP70 in tumor cells was enhanced obviously by thermochemotherapy.Conclusion Special high expression of HSP70 in the tumor cells was induced by thermochemotherapy. With the antigen presenting action and other action,HSP70 have special antitumor effect.
