ABSTRACT
Objective To investigate the application value of the liquid‐based cytology test (TCT) and the DNA quantitative analysis in cervical lesions screening .Methods 2 883 cases of TCT ,1 742 cases of DNA quantitative analysis and 333 cases of TCT combined with the DNA quantitative analysis were performed the retrospective analysis for investigating their clinical significance in diagnosing the cervical lesions .Results The positive coincidence rates of TCT ,DNA quantitative analysis and their combined detec‐tion were 43 .86% ,68 .04% and 81 .16% respectively .There was statistically significant difference in the positive coincidence rates for diagnosing CIN Ⅰand above between TCT and the DNA quantitative analysis (P<0 .01);the positive coincidence rates of the combined detection had statistical difference compared with TCT and the DNA quantitative analysis (P<0 .01) .The sensitivity and the specificity of TCT for discovering the cervical lesions were 69 .44% and 92 .42% respectively ;which of the DNA quantitative a‐nalysis were 85 .71% and 87 .89% respectively ;while which of combined detection were 96 .55% and 95 .89% respectively .Conclu‐sion The DNA quantitative analysis and TCT have the higher clinical diagnostic value in the cervical lesion screening .Their com‐bined detection can more effectively increase the detection rate of cervical lesions .
ABSTRACT
Purpose To investigate the expression of TPX2 in breast cancer, analyze the correlation between its expression and clinico-pathologic characteristics and explore the significances of TPX2 in the treatment and prognosis of breast cancer. Methods Expression of TPX2 in breast cancer tissues, adjacent tissue of cancer and normal breast tissue was examined by immunohistochenistry SP method. The mRNA expression of TPX2 in breast cancer tissues, adjacent tissue of cancer and normal breast tissue was detected by reverse-transcription polymerase chain reaction ( RT-PCR) . Results The expression of TPX2 is significantly higher in breast cancer tissues (75. 86%) compared with adjacent tissue of cancer (40. 00%) and normal breast tissue (5. 00%). And the expression of TPX2 cor-related with tumor grade and lymph node metastasis (P0. 05). The expression of TPX2 mRNA is also significantly higher in breast cancer tissues ( 1. 465 7 ± 0. 136 6 ) compared with adjacent tissue of cancer (0. 923 3 ±0. 114 8) and normal breast tissue (0. 326 9 ±0. 097 3) (P<0. 01). Conclusion High expression of TPX2 in breast cancer correlated with tumor grade and lymph node metastasis, so TPX2 might be a risk factor in the tumorigenesis, progression and lymph node metastasis in breast cancer.
