Purpose: This study aimed at analysing long-term oncologic outcomes in prostate cancer patients with limited nodal disease (1-2 positive lymph nodes) without adjuvant therapy after radical prostatectomy (RP). Methods: We retrospectively analysed data of 209 pN1 patients who underwent RP between January 1998 and 2010 with one (160) or two (49) histologically proven positive lymph nodes (LNs) without adjuvant treatment. Biochemical recurrence-free survival, metastasis-free survival and cancer-specific survival (CSS) were reported. In multivariable regression analyses further prognosticators of oncologic outcome in these patients were analysed. Results: Median follow-up was 60.2 months. There was no significant difference in oncologic outcome between patients with one and two positive LNs. 73.1% (76.7%) of patients with one (two) positive LNs had biochemical recurrence during the follow-up period, 20.0% (25.6%) developed metastasis and 8.1% (6.1%) died of their disease. The only factors significantly associated with oncologic outcome in multivariable analysis were Gleason score and pT-stage. Conclusions: Patients with limited nodal disease (1-2 positive LNs) without adjuvant therapy showed favourable CSS-rates above 94% after 5 years. A subgroup of these patients (37%) remained metastasis-free without need of salvage treatment.

    The article reports that as of 2013, the radical treatment options for high risk prostate cancer (Pca) are radiotherapy (RT) and radical prostatectomy (RP). Since 10-year cancer specific survival (CSS) rates of more than 90% have been described, surgery for high risk Pca is gaining popularity. A...

    Lymph node metastases associated with prostate cancer (PCa) has been shown to be a poor prognostic factor. The role of pelvic lymph node dissection (PLND) itself in relation to survival remains unclear, however. A Medline search was conducted to address this issue. The following conclusions were...
