Fig. 1 Kaplan-Meier plot of progression free survival stratified by presence (n=29) or absence (n=37) of ulceration on biopsy. Log-rank test identified a statistically significant decrease in survival for patients with ulceration on biopsy (p=0.002).
Fig. 2 Kaplan-Meier plot of progression free survival stratified by presence (n=52) or absence (n=10) of tumor-infiltrating lymphocytes. Log-rank test identified a statistically significant decrease in survival for patients with absent TILs on biopsy (p=0.044).
Supplementary Figure 1: Kaplan-Meier plot of progression free survival stratified by present-brisk (n=7), present-nonbrisk (n=45), or absent (n=10) tumor-infiltrating lymphocytes at biopsy. Log-rank did not identify statistically significant differences between the groups (p=0.129).
