This study analysed the immunohistochemical expression of the CAF-1/p60 protein in laryngeal cancers. CAF-1/p60 assumes an independent discriminative and prognostic value in laryngeal neoplasms; the presence of this protein in carcinoma in situ compared with laryngeal precancerous and larynx infiltrating tumours. We assessed the immunohistochemical expression of CAF-1/p60 in 30 cases of moderate and/or severe dysplasia, 30 cases of carcinoma in situ and 30 cases of laryngeal squamous cell carcinoma (LSCCs). CAF-1/p60 expression increased significantly according to the high index of neoplastic cellular replication; therefore, CAF-1/p60 was overexpressed in neoplastic cells and its moderate-severe expression is correlated with poorer prognosis compared to less expression. In conclusion, overexpression of the CAF-1/p60 protein is related to a risk of higher morbidity and mortality and is a reliable independent prognostic index of laryngeal carcinoma. CAF1-p60 protein overexpression can be used in cancer management as an indicator of malignant evolution, especially in carcinoma in situ.
本研究分析了CAF-1/p60蛋白在喉癌中的免疫组化表达。CAF-1/p60在喉肿瘤中具有独立的鉴别和预后价值;与喉癌前病变和浸润性肿瘤相比,原位癌中该蛋白的存在情况。我们评估了30例中重度发育异常、30例原位癌和30例喉鳞状细胞癌(LSCC)中CAF-1/p60的免疫组化表达。根据肿瘤细胞高复制指数,CAF-1/p60表达显著增加;因此,CAF-1/p60在肿瘤细胞中过表达,与低表达相比,其中度至重度表达与较差的预后相关。总之,CAF-1/p60蛋白过表达与更高的发病率和死亡率风险相关,是喉癌可靠的独立预后指标。CAF1-p60蛋白过表达可作为恶性进展的指标用于癌症管理,尤其是在原位癌中。
