Hypothesis
Can micrometastases be identified in histologically negative groin nodes and is there an association between clinical recurrence and micrometastases?
Conclusion
Women with micrometastases are at a significantly increased risk of recurrence compared to those without.
Supporting Evidence
- 42% of women in the study had micrometastases detected.
- Women with micrometastases had a 20-fold higher risk of recurrence.
- Only one of the 18 women without micrometastases recurred.
Takeaway
This study found that some women with vulvar cancer who seemed cancer-free actually had tiny cancer cells that could lead to a higher chance of getting sick again.
Methodology
Retrospective analysis of women with node-negative SCC, using immunohistochemistry to detect micrometastases.
Potential Biases
Potential bias due to the retrospective nature of the study and exclusion of cases with missing data.
Limitations
The study had a small sample size and relied on historical data, which may not reflect current practices.
Participant Demographics
Median age at diagnosis was 70 years, with a range from 30 to 94.

Confidence Interval
