Staging of melanoma

In the 2010 AJCC staging of melanoma, which of the following feature replaces Clark’s level as a primary criterion for defining T1b in thin melanomas? Thin melanoma is <1mm in thickness with 95% 5 year survival. Increasing primary tumor mitotic rates, expressed per square millimeter, were found to be associated with declining survival rates, particularly in thin melanomas, as reflected in the most recent AJCC staging scheme.

Breslow used a lot more now. Clark levels really only useful if you’re dealing with a thin melanoma (if it’s Clark 4 or 5, then it’s still a bad prognosis).
