Nationwide prevalence of lymph node metastases in Gleason score 3 + 3 = 6 prostate cancer.

چکیده
Based on revisions of Gleason scoring in 2005, it has been reported that nodal metastases at radical prostatectomy in Gleason 3 + 3 = 6 (GS6) prostate cancer are extremely rare, and that GS6 cancers with nodal metastases are invariably upgraded upon review by academic urological pathologists. We analysed the prevalence and determinants of nodal metastases in a national sample of patients with GS6 cancer.We utilised the SEER database to identify patients diagnosed with GS6 prostate cancer during 2004-2010 who had radical prostatectomy and ≥1 lymph node(s) examined. We calculated the prevalence of nodal metastases and constructed a multivariable logistic regression model to identify factors associated with nodal metastases. Among 21,960 patients, the prevalence of nodal metastases was 0.48%. Older age, preoperative PSA >10 ng/mL, and advanced stage were positively associated with nodal metastases. Lymph node metastases in GS6 cancer are more prevalent in a nationwide population compared to academic centres. Revised guidelines for Gleason scoring have made GS6 cancer a more homogeneously indolent disease, which may be relevant in the era of active surveillance. We submit that lymph node metastases in GS6 cancer be used as a proxy for adherence to the 2005 ISUP consensus on Gleason grading.

Prevalence of Lymph Node Metastasis in Radical Prostatectomy; A Retrospective and Multicenter Study in Iran
Lymph node (LN) metastasis is considered an important prognostic factor in patients with prostate cancer. The aim of this study was to determine the rate of LN metastasis among an Iranian population who underwent radical prostatectomy (RP) with pelvic LN dissection (PLND). In a retrospective review of medical records, 450 RP cases were included and the data on LN metastasis were extracted from ...
متن کاملDisease-specific death and metastasis do not occur in patients with Gleason score ≤6 at radical prostatectomy.
OBJECTIVES To assess the metastasis-free survival (MFS) and disease-specific survival (DSS) in men with Gleason score ≤6 prostate cancer at radical prostatectomy (RP). PATIENTS AND METHODS We included 1101 consecutive RP patients operated between March 1985 to July 2013 at a single institution. The outcome variables were MFS and DSS. The postoperative survival was estimated by the Kaplan-Meie...
متن کاملThe impact of discordance between biopsy and pathological Gleason scores on survival after radical prostatectomy.
PURPOSE Although discordance in the Gleason score between biopsy and radical prostatectomy specimens has been well recognized, the prognostic importance of this discrepancy has not been definitively established. We investigated the association of Gleason score discordance with postoperative systemic progression and death from prostate cancer. MATERIALS AND METHODS We evaluated the records of ...
