RESUMO
OBJECTIVES: This study explored the impacts of peri-operative changes in the neutrophil-to-lymphocyte ratio (NLR) on the survival rate after radical nephroureterectomy. METHODS: This retrospective analysis included a multicentric cohort of patients diagnosed with upper tract urothelial carcinoma (UTUC) who had undergone radical nephroureterectomy from 2012 to 2021. We assessed the preoperative NLR, postoperative NLR, delta-NLR (difference between postoperative and preoperative NLRs), and NLR change (ratio of postoperative to preoperative NLR). Additionally, patients were categorized according to increases in their preoperative and/or postoperative NLRs. Associations of survival with peri-operative changes in the NLR were investigated using Cox multivariate regression models. RESULTS: A total of 488 patients were included in the study, with a median age of 73 years. Among the patients, 105 (21.5%) exhibited elevated preoperative and postoperative NLRs, 88 (18.0%) exhibited elevated preoperative NLR only, 53 (10.9%) exhibited elevated postoperative NLR only, and 242 (49.6%) exhibited normal NLRs. Multivariate analysis indicated significant negative correlations between both preoperative and postoperative increased NLRs and oncological outcomes, including nonurothelial tract recurrence-free survival and cancer-specific survival (hazard ratio [HR]: 1.65, P = 0.017; HR: 2.12, P = 0.014, respectively). CONCLUSION: This is the first study to evaluate the association between peri-operative changes in the NLR and the outcomes of patients with UTUC who underwent radical nephroureterectomy. Patients with elevated NLRs at both time points experienced considerably worse outcomes. Further research should explore whether increases in the NLR during long-term follow-up could indicate impending disease recurrence.
RESUMO
PURPOSE: The aim of this study was to investigate the oncologic efficacy of combining docetaxel with androgen deprivation therapy (ADT) versus nonsteroidal antiandrogen (NSAA) with ADT in patients with high-volume metastatic hormone-sensitive prostate cancer (mHSPC) with focus on the effect of sequential therapy in a real-world clinical practice setting. METHODS: The records of 382 patients who harbored high-volume mHSPC, based on the CHAARTED criteria, and had received ADT with either docetaxel (n = 92) or NSAA (bicalutamide) (n = 290) were retrospectively analyzed. The cohorts were matched by one-to-one propensity scores based on patient demographics. Overall survival (OS), cancer-specific survival (CSS), progression-free survival (PFS), including time to castration-resistant prostate cancer (CRPC), and time to second-line progression (PFS2) were compared. 2nd-line PFS defined as the time from CRPC diagnosis to progression after second-line therapy was also compared. RESULTS: After matching, a total of 170 patients were retained: 85 patients treated with docetaxel + ADT and 85 patients treated with NSAA + ADT. The median OS and CSS for docetaxel + ADT versus NSAA + ADT were not reached (NR) vs. 49 months (p = 0.02) and NR vs. 55 months (p = 0.02), respectively. Median time to CRPC and PFS2 in patients treated with docetaxel + ADT was significantly longer compared to those treated with NSAA (22 vs. 12 months; p = 0.003 and, NR vs. 28 months; p < 0.001, respectively). There was no significant difference in 2nd-line PFS between the two groups. CONCLUSIONS: Our analysis suggested that ADT with docetaxel significantly prolonged OS and CSS owing to a better time to CRPC and PFS2 in comparison to NSAA + ADT in high-volume mHSPC.

BACKGROUND: Randomized trials showed the survival benefits of the combined use of androgen receptor axis-targeted agents with androgen deprivation therapy in metastatic hormone-sensitive prostate cancer (mHSPC), regardless of the risk. However, treating patients with low-risk mHSPC with such intensive treatment is still debatable. METHODS: This retrospective study included 155 low-risk patients among 467 mHSPC patients treated in our affiliated institutions. The association between predictive factors and treatment outcomes was estimated using the Kaplan-Meier method and log-rank test. Predictive factors for castration resistant prostate cancer (CRPC)-free survival were investigated using Cox regression analyses. RESULTS: During the median follow-up of 39 months, 38.7% of patients developed CRPC and 14.2% died. In the multivariate analyses, a presence of Gleason pattern 5 (hazard ratio [HR] 2.04), high alkaline phosphatase (HR 1.007) and high lactate dehydrogenase (HR 1.009) were significant predictive factors for shorter CRPC-free survival. Finally, 155 patients were stratified into favorable- and unfavorable-risk groups based on the numbers of the predictive factors. The overall survival (OS) in the unfavorable-risk group (total scores: 2-3) was significantly worse than that of the favorable-risk group (total score: 0-1) (P = 0.02). This prognostic model was assessed with 50 low-risk mHSPC patients from the external validation dataset and found both the time to CRPC, and the OS in the unfavorable-risk group was significantly worse than that of the favorable-risk group (P < 0.01). CONCLUSIONS: The combination of Gleason pattern 5, high alkaline phosphatase and lactate dehydrogenase can predict those with worse OS in low-risk mHSPC patients.

OBJECTIVES: To identify risk factors for developing recurrent bladder cancer in patients who underwent surgical resection for urothelial carcinoma of the upper urinary tract. METHODS: We retrospectively analyzed 322 patients who underwent surgical resection for urothelial carcinoma of the upper urinary tract at the Jikei University Hospital and our affiliated hospitals between January 2005 and July 2011. Univariate and multivariate analyses by using the Cox proportional hazards model were performed to determine the risk factors for intravesical recurrence after nephroureterectomy in these 322 patients. RESULTS: Of the 322 patients, 111 patients (34.5%) developed recurrent bladder cancer after a median interval of 8.0 months. On multivariate analysis, the presence of a superficial tumor and the presence of a ureteral tumor were independent predictors for intravesical recurrence. CONCLUSION: The risk factors for developing recurrent bladder cancer were the presence of a superficial tumor and the presence of a ureteral tumor. Further investigation is required to evaluate the efficacy of perioperative intravesical therapy for the prevention of intravesical recurrence.

BACKGROUND: The critical role of radiographic assessment at the time of castration-resistant prostate cancer (CRPC) diagnosis is underscored by this study. We performed a retrospective analysis of radiographic changes in metastasis from the time of diagnosis of metastatic hormone-sensitive prostate cancer (mHSPC) to CRPC diagnosis. We also explored its impact on prognosis post-CRPC. MATERIALS AND METHODS: We retrospectively analyzed 98 men who underwent radiographic examinations (bone scans and computed tomography [CT]) at the time of CRPC diagnosis. When radiographic studies demonstrated progression at CRPC diagnosis, patients were assigned to the radiographic progressive disease (rPD) group. The remaining patients were placed in the "non-rPD" group. The overall survival (OS) post-CRPC was compared between the 2 groups. RESULTS: The median OS post-CRPC was significantly shorter in the rPD group (n = 50) compared to the non-rPD group (n = 48) (32 months vs. not reached, P = .0124). Multivariate analysis showed that radiographic progression and shorter time to CRPC were associated with a shorter OS post-CRPC (hazard ratio [HR] = 3.14; 95% confidence interval [CI], 1.21-8.12, P = .019). CONCLUSION: Radiographic progression at the point of CRPC diagnosis independently predicts a shorter OS post-CRPC in patients with mHSPC. Therefore, assessing radiographic changes at the time of CRPC diagnosis could be instrumental in managing CRPC in patients with mHSPC.
