Summary
Vascular endothelial growth factor (VEGF) levels are significantly elevated in cervical cancer tissues compared to benign tissues. Higher VEGF concentrations correlate with advanced tumor size, invasion, and metastasis, suggesting its role as a marker for disease severity.
Area of Science:
- Oncology
- Molecular Biology
- Gynecologic Pathology
Background:
- Cervical carcinoma is a significant global health concern.
- Vascular Endothelial Growth Factor (VEGF) is implicated in tumor angiogenesis and progression.
Purpose of the Study:
- To quantify intratumoral vascular endothelial growth factor (VEGF) protein levels in cervical cancer.
- To investigate the correlation between VEGF levels and clinical-pathological characteristics of cervical carcinoma.
Main Methods:
- Intratumoral VEGF protein concentrations were measured in 104 cervical cancer patients.
- 30 benign cervical tissue specimens served as controls.
- VEGF levels were correlated with tumor size, invasion depth, lymphovascular emboli, and lymph node metastasis.
Main Results:
- Cervical cancer tissues exhibited significantly higher median VEGF levels than benign tissues (180.0 vs. 0.0 pg/mg, P < .001).
- Elevated VEGF concentrations were associated with larger tumor size (>4 cm), deep stromal invasion, lymphovascular emboli, parametrial invasion, and pelvic lymph node metastasis.
- VEGF protein levels positively correlated with tumor size (r = 0.340, P < .001).
Conclusions:
- Intratumoral VEGF levels in cervical cancer correlate strongly with local tumor progression and metastasis.
- VEGF may serve as a valuable biomarker for assessing the severity of cervical cancer.
- Further research into VEGF's role in cervical cancer progression is warranted.
