摘要
探讨肝癌肝动脉栓塞化疗后肿瘤的病理及某些分子生物学的变化。方法:从1992年1月到1997年12月,结合临床对手术切除的原发性肝癌术前曾接受肝动脉栓塞化疗的117例标本作大体病理、镜下病理、免疫组化方法的肿瘤增殖细胞核抗原(PCNA),p53蛋白及抑癌基因p53PCR技术的检测。结果:肉眼见坏死组织约占肿瘤体积不到50%的有32例,坏死占50%~90%的有54例,90%以上而有未完全坏死的有18例,100%的有13例。镜下仍见有肿瘤细胞的有111例,全部为坏死组织而未见肿瘤细胞的有6例。肿瘤增殖细胞核抗原(PCNA)高指数的有72例(649%),p53表达强阳性的有85例(766%)。结论:本组资料表明,肝动脉栓塞化疗能使大部分肿瘤细胞坏死,但仅有极少部分全部坏死。
Objective: To observe the pathological and molecular changes of the primary liver carcinoma after chemoembolization. Methods: From June 1992 to December 1997,hepatectomy had been performed in 117 patients whom were treated with TACE before operation.Pathological study,PCNA and p53 assessment of these specimens had been done. Results:Only 5% cases displayed a complete tumor cell necrosis, 73% cases displayed a necrosis in more than of half of tumor cells.High labeling index of PCNA appeared in 64 9% and over expression of p53 protein in 76 6%,mutations of p53 alterations in 36% of the patients.Conclusion: TACE can cause the tumor cells necrosis completely.When the tumor cells were still alive,most of them were in proliferation active stage.
