Univariate comparative analysis according to biochemical response after RP (Table 4) shows no difference between age (p = 0.359), mortality (p = 0.965), PSA (p = 0.081), Gleason score (p = 0.526), grade group (p = 0.599), weight (p = 0.465), BMI (p = 0.127) and obesity rate (p = 0.161) at diagnosis between patients in remission and patients with BCR after RP. This evidence concerns the gene BCR and obesity disorder.
