Relationship between p27^Kip1 Levels and Depth of Tumor Growth of Primary Melanomas

Tumor type	Immunohisto- chemistry^*	Number of patients	Depth of growth^† (mm)
Superficial	High	24	1.15 P = 0.56
	Low	55	1.15
Nodular	High	13	2.30 P = 0.05
	Low	21	5.20

*Scored as described in Materials and Methods: <50% cells stained, low expression; >50% cells stained, high expression. Changing the cutoff to high when more than 50% of the cells were p27 positive did not alter the outcome. A total of 113 tumors were analyzed.

^†Measured as the median thickness in each group.
