Hypothesis
This study aimed to investigate p27 expression in the normal endometrium and endometrioid adenocarcinoma of the uterine corpus and the correlation of its expression with cell proliferation and clinicopathological parameters.
Conclusion
High p27 expression was linked to higher grades of endometrioid adenocarcinoma and associated with poor prognosis.
Supporting Evidence
- p27 staining was positive in 97.6% of endometrioid adenocarcinomas.
- The labelling index of p27 expression increased significantly with higher histological grades.
- High p27 expression was correlated with clinicopathological parameters such as FIGO stage and lymph node metastasis.
Takeaway
The study found that a protein called p27, which usually helps control cell growth, was found in higher amounts in more aggressive types of uterine cancer, suggesting it might be a sign of worse outcomes.
Methodology
Immunohistochemical staining for p27 and Ki-67 was performed on tissue samples from endometrioid adenocarcinomas and normal endometria.
Participant Demographics
Patients' ages ranged from 30 to 83 years, with a median age of 56 years.
Statistical Information
P-Value
P=0.03 for FIGO stage correlation
Statistical Significance
p<0.05
