Kaplan-Meier curves for Recurrence-Free Survival (RFS) in nuclear grade I DCIS, as a function of positive staining intensity. A shows that 1 of 7 GS-1-negative subjects had a recurrence in their 4th year of follow-up, while 4 of 6 GS-positive subjects had recurrences in their 6th and 7th year of follow-up (log-rank P = 0.15). B shows that none of the 6 VVA-negative subjects had recurrences during follow-up, whereas 5 of the 7 VVA-positive subjects had recurrences in their 4th, 6th, and 7th year of follow-up (log-rank P = 0.02).
