Regarding the nuclear expression of LDOC1 (Figure 1b), 11% of the vulvar carcinoma tissue sections showed a weak color reaction (IRS 1–2), 33.1% showed a moderate color reaction (IRS 3, 4, 6), and 3.1% of the specimens showed a strong color reaction (IRS 8). This evidence concerns the gene LDOC1 and vulvar carcinoma.
