Background and purpose The aim of this study was to evaluate chronologic changes in lower urinary tract symptoms (LUTS), health-related (HR) quality of life (QOL), and disease-specific QOL during the first 12 months after salvage radiotherapy (SRT) for biochemical recurrence of prostate cancer in patients who underwent radical prostatectomy. Materials and methods In 81 patients who received SRT (70 Gy/35fr/7 weeks), International Prostate Symptom Score (IPSS), 36-Item Short Form scores, and UCLA-Prostate Cancer Index (UCLA-PCI) were recorded before, during, and immediately after SRT, and 1–12 months after the completion of SRT. Results The total IPSS and storage symptom-related sum were significantly increased following initiation of SRT, and returned to the baseline 6 months after SRT. For three of eight domains of HRQOL, and the physical component summary score showed transient deterioration in the period between completion of SRT and 1 month following SRT. The UCLA-PCI for urinary function/bother and bowel function/bother was affected until 1–6 months after SRT. Conclusions This is the first report to concurrently evaluate detailed chronologic changes in LUTS and QOL in patients who received SRT. Knowledge of changes in LUTS and QOL outcomes associated with SRT may influence treatment recommendations and enable patients to make better-informed decisions. [ABSTRACT FROM AUTHOR]

Purpose: High-neutrophil to lymphocyte ratio (NLR) values have been shown to be associated with a poor prognosis in many human malignant tumors. We evaluated the correlation of the NLR with other variables in patients with muscle-invasive bladder cancer after radical cystectomy (RC); in particular, we evaluated chronological changes in the postoperative NLR.Methods: We included the data from a total of 110 patients who underwent RC for muscle-invasive bladder cancer. The NLR was calculated using complete blood counts determined before RC. Kaplan-Meier and Cox proportional regression analyses of recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) were performed to identify significant prognostic variables.Results: The median patient age was 72 years (41-91 years). In univariate analysis, the pretreatment NLR (≥2.6 vs.<2.6) was associated with RFS (hazard ratio [HR] = 2.41, P = 0.008), CSS (HR = 2.89, P = 0.006), and OS (HR = 2.73, P = 0.002). In multivariate analysis, an NLR≥2.6 and an infiltrative growth pattern at the tumor invasion front were significantly associated with RFS (HR = 2.61, P = 0.023), CSS (HR = 2.58, P = 0.08), and OS (HR = 2.77, P = 0.004). Postoperative chronological analysis revealed that the NLR of 68 patients without recurrence remained low during follow-up, whereas the NLR of the remaining 42 patients with recurrence increased significantly in the last visit before recurrence was detected radiographically (P< 0.01).Conclusions: The NLR and tumor growth pattern were strong predictors of prognosis for patients undergoing RC. Our results suggest that an increase in the NLR during follow-up after RC is a potential marker for the early detection of recurrence. [ABSTRACT FROM AUTHOR]
