Prognosis in stage D‐1 prostate cancer relative to anatomic sites of nodal metastases

Academic Article

Abstract

  • The investigators of the National Prostatic Cancer Treatment Group (NPCTG) have entered 212 patients with surgically confirmed stage D‐1 prostate cancer in studies to determine the efficacy of adjuvant therapy after either definitive surgery (Protocol 900) or definitive radiotherapy (Protocol 1000). Follow‐up indicates that this group represents 70% of all patients with recurrent disease. Because patients with less than 20% nodal involvement were found to have a statistically significant better progression‐free‐survival (PFS) than those with greater than 20% nodal involvement, we examined the exact anatomic sites of nodal metastases. The status of obturator, external iliac, internal iliac, and common iliac nodes was compared to PFS and overall survival in 198 patients with D‐1 disease in both protocols. Results demonstrate no significant difference in either PFS or overall survival relative to anatomic sites of positive nodes. These data suggest that although minimal pelvic nodal metastasis is consistent with improved PFS, there is no predictable anatomic distribution of disease consonant with that better prognosis.
