Title: Expression and clinical significance of PTEN and CyclinD1 protein in patients with PTC
Abstract: Objective
To explore the expression and clinical significance of PTEN and CyclinD1 protein in patients with PTC, and to provide theoretic evidence on prognosis evaluation and clinical personalized treatment.
Methods
76 patients diagnosed with PCT, treated in Quhua Hospital in Zhejiang Province, from Jan. 2015 to Jan. 2017, were enrolled. The expression of PTEN and CyclinD1 protein was detected by EnVision two-step immunohistochemical method, and their correlation with clinical pathologic characteristic of PTC was analyzed.
Results
The negative rate of PTEN of the patients enrolled was 73.68% (56/76) , and compared with negative rate of tumor-adjacent tissue (19.74%, 15/76) , demonstrated statistic significance (χ2=44.429, P<0.05) . The down regulation of PTEN expression was positively related with pathological stage, tumor lymph node metastasis and sex (P<0.05) . The positive rate of CyclinD1 was 76.32% (58/76) , and compared with positive rate of tumor-adjacent tissue (13.16%, 10/76) , demonstrated statistic significance (χ2=61.311, P<0.05) . The up regulation of CyclinD1 protein was positively related with pathological stage and tumor lymph node metastasis (P<0.05) .
Conclusions
The down regulation of PTEN and up regulation of CyclinD1 are closely related with PTC pathological stage and tumor lymph node metastasis. Detection of PTEN and CyclinD1 would be benefit to early evaluation on prognosis of PTC patients.
