Among the PC patients, the MSMB levels in serum were not associated with Gleason score in prostatectomy or biopsy specimens (p = 0.6621; 0.819, respectively; Table 6), but serum MSMB levels and pT-stage (p = 0.0288) and age at diagnosis (p = 0.0452) tended to be weakly associated in prostatectomy cases (Table 6). This evidence concerns the gene MSMB and pachyonychia congenita.
