IMPACT OF PREOPERATIVE STAGING OF PROSTATIC CANCER ON POSITIVE SURGICAL MARGIN INCIDENCE FOLLOWING RADICAL PROSTATECTOMY
Background Despite improvement of the equipment for polyfocal biopsy of the prostate gland (PBPG), a sufficient percent of data divergence in morphological characteristics of the prostate cancer (PC) at preoperative and postoperative stages is noted. Besides data of PBPG and clinical stage are quite...

| description | Background Despite improvement of the equipment for polyfocal biopsy of the prostate gland (PBPG), a sufficient percent of data divergence in morphological characteristics of the prostate cancer (PC) at preoperative and postoperative stages is noted. Besides data of PBPG and clinical stage are quite important part of nomograms applied for indication detections for lymphadenectomy and neuro-sparing technique during radical prostatectomy (RPE). Regarding this fact error limits in clinical assessment of the primary tumor could influence surgical outcomes. Aim The aim of the present study was assessment of coincidence frequency of morphological characteristics of PC according to transrectal PBPG and clinical examination with morphological assessment of operational material after radical prostatectomy (RPE). Evaluation of errors influence on frequency of positive surgical margin (PSM) at clinical staging of PC was performed. Materials and methods Data of transrectal PBPG and operational material after RPE in 276 patients with PC were studied. Both biopsy and operative materials were exposed to preservation in 10% buffering solution of formalin, and after automatic conducting was painted by hematoxylin-eozinom. Each histologic conclusion was formed by at least two pathologists who estimated PBPG and samples after RPE in the same structure. The interrelation between staging errors and frequency of PSM was studied. Outcomes Analysis For patients with locally-advanced PC the adequate staging according to TPFB was noted only in 18,7% cases. Errors for clinical staging of the localized PC had no significant influence on PSM frequency: 3.7% in patients with correct staging and 6,5% in patients with poor staging with stage migration within pT2b - pT2c (p = 0,07). With down-staging of locally-advanced PC which was observed in 81,3% patients, significant increase in PSM frequency reached 23,1% in comparison with proper staging - 6.6% patients (p |
