In contrast, no significant differences in sex (P = 0.815), age (P = 0.247), tumor size (P = 0.791), depth (P = 0.807), FNCLCC histological grade (P = 0.113), tumor differentiation (P = 1.000), degree of tumor necrosis (P = 0.615), cyclinD1-positive (P = 0.1623), or ErbB2/HER2-positive (P-value, not calculable). Here, CCND1 is linked to neoplasm.
