Hypothesis
Can the expression of p53 and mdm2 predict lymph node metastases in squamous cell carcinoma of the vulva?
Conclusion
Overexpression of p53 is a late event in vulvar carcinoma, and neither p53 nor mdm2 expression can predict lymph node metastases.
Supporting Evidence
- Overexpression of p53 was seen in 56% of lymph node metastases.
- No relation was found between overexpression of p53 in primary tumors and lymph node metastases.
- Expression of mdm2 was seen in 14% of primary tumors, but none in lymph node metastases.
Takeaway
This study looked at two proteins, p53 and mdm2, in vulvar cancer to see if they could help predict if the cancer had spread to lymph nodes, but they found they couldn't.
Methodology
The study analyzed archival material of 141 T1 and T2 vulvar tumors and their lymph node metastases, using immunohistochemistry to detect p53 and mdm2 expression.
Limitations
The study may be limited by the retrospective nature and the specific population studied.
Participant Demographics
Patients with squamous cell carcinoma of the vulva.
