CCND1 and breast cancer: Likewise, cyclin D1 expression was shown to correlate with increased breast cancer-specific survival (P = 0.020; HR = 4.26; 95.0% CI = 1.12, 16.1) (Figure 3A) and increased overall survival (P = 0.013; HR = 3.93; 95.0% CI = 1.23, 12.6) (Figure 3B), but it had no significant association with disease-free survival (data not shown).
