Journal Article
Regional location of lymph node metastases predicts survival in patients with de novo metastatic prostate cancer
2023
Overview
To report the regional locations of metastases and to estimate the prognostic value of the pattern of regional metastases in men with metastatic hormone-sensitive prostate cancer (mHSPC), we retrospectively analyzed 870 mHSPC patients between November 28, 2009, and February 4, 2021, from West China Hospital in Chengdu, China. The patients were initially classified into 5 subgroups according to metastatic patterns as follows: simple bone metastases (G1), concomitant bone and regional lymph node (LN) metastases (G2), concomitant bone and nonregional LN (NRLN) metastases (G3), lung metastases (G4), and liver metastases (G5). In addition, patients in the G3 group were subclassified as G3a and G3b based on the LN metastatic plane (below or above the diaphragm, respectively). The associations of different metastatic patterns with castration-resistant prostate cancer-free survival (CFS) and overall survival (OS) were analyzed by univariate and multivariate analyses. The results showed that patients in G1 and G2 had relatively favorable clinical outcomes, patients in G3a and G4 had intermediate prognoses, and patients in G3b and G5 had the worst survival outcomes. We observed that patients in G3b had outcomes comparable to those in G5 but had a significantly worse prognosis than patients in G3a (median CFS: 8.2 months vs 14.3 months, P = 0.015; median OS: 38.1 months vs 45.8 months, P = 0.038). In conclusion, metastatic site can predict the prognosis of patients with mHSPC, and the presence of concomitant bone and NRLN metastases is a valuable prognostic factor. Furthermore, our findings indicate that the farther the NRLNs are located, the more aggressive the disease is.
