As shown in Table 4, 41 of the 49 DCIS recurrence patients showed both FAP-a positive in stromal fibroblasts and GOLPH3 positive in carcinoma cells (FAP-a+GOLPH3+), three of them showed FAP-a−GOLPH3+, five showed FAP-a−GOLPH3−, while none of them showed FAP-a+GOLPH3−. This evidence concerns the gene FAP and ductal breast carcinoma in situ.
