Hypothesis
Are tumour thickness and level of invasion suitable parameters for a prognosis-oriented description of primary malignant melanomas?
Conclusion
Tumour thickness is the most significant predictor of survival in melanoma patients, and the TNM classification can be optimized for better prognostic accuracy.
Supporting Evidence
- Breslow's tumour thickness is the most powerful predictor of patient survival.
- Grading cutoffs at 1, 2, and 4 millimeters improve prognostic classification.
- Locoregional metastasis has a better prognosis than regional lymph node involvement.
Takeaway
This study looked at how thick a melanoma is to see how likely it is to be dangerous. Thicker melanomas are more likely to cause problems.
Methodology
Data from 2,495 patients with invasive malignant melanomas were analyzed using multivariate regression analysis to determine survival rates based on tumour thickness and other factors.
Limitations
The study only included patients from three German universities and may not be generalizable to other populations.
Participant Demographics
Patients were from three German universities, with a follow-up period of at least three months.
