Predicting outcome in melanoma: where are we now?

Melanoma incidence continues to rise in most countries. This is of grave concern, given the mortality rate in a relatively young population.

This overview comprehensively reviews relevant literature, with the focus on the last 5 years, and discusses the current state of traditional and emerging novel methods of staging for melanoma and their effect on prognosis in this population.
