Hypothesis
The study aims to evaluate the cytosol activity of thymidine phosphorylase in tumor samples from patients with endometrial cancer.
Conclusion
The cytosol TP activity in endometrial cancer is significantly higher than in normal endometrium and correlates with PD-ECGF/TP protein expression and microvessel density.
Supporting Evidence
- The mean activity of TP in tumor samples was significantly higher than in normal endometrial samples.
- A positive correlation was found between cytosol TP activity and PD-ECGF/TP protein expression.
- Microvessel density was significantly higher in malignant tumors compared to normal endometrium.
Takeaway
This study found that a substance called thymidine phosphorylase is much more active in endometrial cancer than in normal tissue, which might help doctors understand how to treat the cancer better.
Methodology
TP activity was measured using a spectrophotometric method in tumor samples, and PD-ECGF/TP protein expression and microvessel density were assessed by immunohistochemical staining.
Limitations
The study did not find significant correlations between TP activity and clinical stages or histopathological grades of endometrial cancer.
Participant Demographics
Patients were postmenopausal women aged 50 to 88 years with histologically confirmed endometrial tumors.
