European PCa patients with shorter BTLs (< 3200 bp) and TTLs (< 2861 bp), were at greater risk for earlier BCR (P = 0.021 and P = 0.0099, respectively; Fig. 4A,B), while no statistical association was found between BTL or TTL and metastasis (Fig. 4C,D). This evidence concerns the gene BCR and posterior cortical atrophy.
