Expression of CyclinD1 in the tissue of endometrial lesions
Pathological type Cases assessed CyclinD1
+ - Positive Rate%*
Simple hyperplasia 27 8 19 30%
Atypical complex hyperplasia 41 20 21 49%
Endometrioid carcinoma 103 54 49 52%
Endometrial serous carcinoma 21 8 13 38%
Clear cell carcinoma 9 6 3 67%

*: Grade and score by the intensity of immunoreactivity staining: 0 point for absent, 1 point for weak, 2 points for moderate and 3 points for strong; then grade by the extent of tissue staining: 0 point for no positive staining cells, 1 point for positive ratio <25%, 2 points for 25%-49%, 3 points for 50%-79% and 4 points for ≥ 80%. Finally, multiply the two score systems: ≤3 points for negative, >3 points for positive.
