First postoperative PSA is associated with outcomes in patients with node positive prostate cancer: Results from the SEARCH database.

Journal Article

OBJECTIVE:To analyze factors associated with metastases, prostate cancer-specific mortality, and all-cause mortality in pN1 patients. MATERIALS AND METHODS:We analyzed 3,642 radical prostatectomy patients within the Shared Equal Access Regional Cancer Hospital (SEARCH) database. Pathologic Gleason grade, number of lymph nodes (LN) removed, and first postoperative prostate-specific antigen (PSA) (<0.2 ng/ml or ≥0.2 ng/ml) were among covariates assessed. Cox regression was used to analyze the association between characteristics and survival outcomes. Kaplan-Meier was used to estimate survival in pN1 patients stratified by first postoperative PSA. RESULTS:Of 3,642 patients, 124 (3.4%) had pN1. There were 71 (60%) patients with 1 positive LN, 32 (27%) with 2 positive LNs, and 15 (13%) with ≥3. Among men with pN1, first postoperative PSA was<0.2ng/ml in 46 patients (51%) and ≥0.2ng/ml in 44 patients (49%). Univariable Cox regression determined pathological Gleason grade (P = 0.021), seminal vesicle invasion (P = 0.010), and first postoperative PSA ≥0.2 ng/ml (P = 0.005) were associated with metastases. First postoperative PSA ≥0.2ng/ml was associated with metastasis on multivariable analysis (P = 0.046). Log-rank analysis revealed a more favorable metastases-free survival in patients with a first postoperative PSA<0.2ng/ml (P = 0.001). Estimated 5-year metastases-free survival rate was 99% for patients with a first postoperative PSA<0.2ng/ml and 87% for ≥0.2ng/ml. CONCLUSIONS:pN1 patients with a first postoperative PSA ≥0.2ng/ml were more likely to develop metastases. First postoperative PSA may be useful in identifying pN1 patients who harbor distant disease and aid in secondary treatment decisions.
