RESUMO
OBJECTIVES: We assessed preoperative factors predicting the poor therapeutic efficacy of holmium laser enucleation of the prostate (HoLEP) in benign prostatic hyperplasia (BPH) patients. METHODS: The present study included 159 patients who underwent HoLEP between August 2015 and June 2021 at our institution. Overall therapeutic efficacy was divided into good and poor therapeutic efficacies according to changes in the international prostate symptom score (IPSS), IPSS quality of life (IPSS-QOL), and the maximum urinary flow rate. Patients were divided into good and poor therapeutic efficacy groups based on findings obtained 3 months after HoLEP, and comparative assessments were performed between the two groups. RESULTS: The therapeutic efficacy of HoLEP was poor in 53 (33.3%) out of 159 patients. Intravesical prostatic protrusion (IPP), IPSS, IPSS-QOL, post-void residual volume (PVR), and the presence of overactive bladder (OAB) were significantly higher in the poor therapeutic efficacy group than in the good therapeutic efficacy group. A multivariable analysis of several factors identified the preoperative presence of OAB and short IPP as independent risk factors for the poor therapeutic efficacy of HoLEP. When treatment efficacy was divided according to risk factors, poor therapeutic efficacy was observed in only 14% of patients with prolonged IPP and the absence of OAB. CONCLUSIONS: The therapeutic efficacy of HoLEP may be poor in patients with OAB and short IPP, resulting in the significant deterioration of lower urinary tract symptoms. Accordingly, it is important to consider the presence or absence of OAB and IPP measurements when selecting indications for HoLEP.

BACKGROUND/AIM: Anthracycline-based chemotherapies including doxorubicin monotherapy are recommended in major guidelines for patients with advanced or metastatic retroperitoneal sarcoma (RPS); however, few studies have reported the outcomes of doxorubicin monotherapy for these patients. We herein investigated the oncological efficacy and safety of doxorubicin monotherapy for patients with advanced or metastatic RPS in real-world clinical practice. PATIENTS AND METHODS: Sixteen patients diagnosed with advanced or metastatic retroperitoneal sarcoma, receiving doxorubicin monotherapy as first-line treatment between February 2017 and March 2023 at our Institution were analyzed. Response rate, progression-free survival (PFS) periods, overall survival (OS) period, and adverse event (AE) profiles were retrospectively investigated. RESULTS: The median age of patients was 69.5 years. Best responses to doxorubicin were as follows: complete response, 0 patients (0.0%); partial response, 3 (18.8%); stable disease, 9 (56.3%); and progressive disease, 4 (25.0%). The objective response rate and disease control rate were 18.8 and 75.0%, respectively. During the observation period (median, 22 months, range=2-53 months), median PFS and OS periods were 8.0 and 24.0 months, respectively. The following AEs Grade ≥3 occurred: neutropenia in 14 patients (87.5%), febrile neutropenia in 5 (31.3%), leukopenia in 2 (12.5%), thrombocytopenia in 1 (6.3%), and heart failure in 1 (6.3%). Grade ≥3 nausea and vomiting did not occur and there was no treatment-related death. CONCLUSION: The oncological outcomes of doxorubicin monotherapy for RPS in real-world clinical practice were not inferior to those of the EORTC trial. The incidence of hematological AEs was higher; however, severe gastrointestinal AEs were prevented by prophylactic antiemetics and there were no treatment-related deaths. Collectively, doxorubicin monotherapy with appropriate prophylactic agents is a valid option for patients with advanced or metastatic RPS.

OBJECTIVES: The objective of this study was to assess the clinical outcomes following combined treatment with pembrolizumab and axitinib as first-line therapy for patients with advanced RCC. METHODS: This study retrospectively included 47 consecutive Japanese patients who were diagnosed with advanced RCC and subsequently received pembrolizumab and axitinib between February 2020 and January 2022. Efficacy and safety of this combined therapy in these patients were comprehensively investigated. RESULTS: The 47 included patients were classified into the following 3 groups by the IMDC system: favorable, 7 (14.9%); intermediate, 24 (51.1%) and poor, 16 (34.0%). Responses to this combined therapy in the 47 patients were as follows: CR, 8 (17.0%); PR, 20 (42.6%); SD, 16 (34.0%) and PD, 3 (6.4%); thus, the ORR was 59.6%. During the observation period, disease progression and death occurred in 19 (40.4%) and 9 (19.1%) patients, respectively, and the median PFS and OS were 18 months and not reached, respectively. Univariate analyses identified the following significant predictors for poor prognostic outcomes: lack of nephrectomy, liver metastasis, bone metastasis, elevated CRP and IMDC poor risk for PFS; and lack of nephrectomy, non-CCC and elevated CRP for OS. AEs and those corresponding to grade ≥ 3 occurred in all (100%) and 30 (63.8%) patients, respectively. CONCLUSIONS: To our knowledge, this is the first study focusing on real-world outcomes following pembrolizumab and axitinib for treatment-naïve advanced Japanese RCC patients, which showed the efficacy and safety of this combined therapy being similar or even superior to those in clinical trial.

OBJECTIVES: The present study comprehensively investigated the significance of several factors reflecting the therapeutic effects of anticancer treatment on overall survival (OS) in advanced urothelial cancer (UC) patients receiving sequential systemic therapy. METHODS: This study included 101 consecutive advanced UC patients who received first-line platinum-based combination chemotherapy followed by second-line pembrolizumab. The impacts of the following factors on OS in these patients were analyzed: responses to chemotherapy, responses to pembrolizumab, progression-free survival (PFS) with chemotherapy, PFS with pembrolizumab, and second PFS (PFS2). RESULTS: The median age of patients was 71 years, and 35 and 66 had UC in the upper urinary tract and bladder, respectively. objective response rate to first-line chemotherapy and second-line pembrolizumab were 37.6% and 19.8%, respectively. Median PFS with chemotherapy, pembrolizumab, and PFS2 were 5, 4, and 9 months, respectively. Uni- and multivariate analyses of the five factors examined identified PFS with pembrolizumab and PFS2 as independent surrogates for OS, with PFS2 (hazard ratio [HR] = 0.23) being more closely associated with OS than PFS with pembrolizumab (HR = 0.31). Furthermore, uni- and multivariate analyses of various prognostic parameters showed the independent impacts of baseline performance status (PS) and neutrophil-to-lymphocyte ratio (NLR) on PFS2. CONCLUSIONS: The present results suggest the potential of PFS2 as an optimal surrogate for OS in advanced UC patients receiving standard sequential systemic therapy and indicate that intensive treatment needs to be considered for those with poor PS and/or high NLR prior to the introduction of first-line chemotherapy.

OBJECTIVES: To assess the postoperative status of clinically localized prostate cancer patients who underwent robot-assisted radical prostatectomy (RARP) with a focus on de novo overactive bladder (OAB). METHODS: The present study included 156 patients who did not have preoperative OAB and underwent RARP between December 2015 and April 2020 at our institution. Patients were divided into the de novo OAB group and non-OAB group based on the findings of overactive bladder symptoms score (OABSS) 6 months after RARP, and comparative assessments were performed between the two groups. RESULTS: Six months after RARP, de novo OAB was detected in 38 (24.4%) out of 156 patients. Body mass index (BMI) and the proportion of patients with hypertension were significantly higher in the de novo OAB group than in the non-OAB group. No significant differences were observed in the other characteristics examined. Furthermore, the preoperative findings of uroflowmetry and a urodynamic study did not significantly differ between the two groups. Despite the lack of significant differences in preoperative OABSS, total international prostate symptom score, the voiding symptom score, storage symptom score, and quality of life score between the two groups, all of these findings 6 months after RARP were significantly worse in the de novo OAB group than in the non-OAB group. Among the several factors examined, only BMI was independently associated with the development of de novo OAB 6 months after RARP. CONCLUSIONS: Patients with a high BMI may develop de novo OAB after RARP, resulting in the significant deterioration of lower urinary tract symptoms.

BACKGROUND/AIM: Sexual function in patients with benign prostatic hyperplasia (BPH) could be affected by surgical intervention, such as holmium laser enucleation of the prostate (HoLEP). The objective of the present study was to investigate whether changes in erectile function (EF) after HoLEP affect postoperative outcomes in patients with BPH. PATIENTS AND METHODS: We retrospectively reviewed 54 consecutive Japanese patients with BPH undergoing HoLEP at our institution between August 2017 and December 2020, and analyzed data obtained before and 6 months after HoLEP, including the Erection Hardness Score (EHS), International Prostate Symptom Score (IPSS), IPSS-Quality of Life (IPSS-QOL), Overactive Bladder Symptom Score (OABSS), and the Medical Outcomes Study 8-Item Short-Form Health Survey consisting of a mental health component summary (MCS) and physical health component summary (PCS). RESULTS: Although no significant differences were observed between preoperative and postoperative EHS, postoperative EHS deteriorated in 19 out of 54 patients. Total IPSS, IPSS-QOL, and OABSS significantly improved after HoLEP, irrespective of the deterioration of EHS; however, despite the lack of significant changes in MCS and PCS in 19 patients with deteriorated EHS, significant improvements in MCS, but not PCS, were postoperatively observed in the remaining 35. A multivariable analysis of several factors identified a preoperative estimated prostate volume >100 cm3 as an independent risk factor associated with the postoperative deterioration of EHS. CONCLUSION: HoLEP had limited impact on postoperative EF in BPH patients; however, favorable QOL may be expected in patients without the postoperative deterioration of EF. Accordingly, it may be important to consider the prostate volume and its effect on postoperative EF when selecting indications for HoLEP.

BACKGROUND: Systemic therapy using immune checkpoint inhibitors (ICIs) has recently become prevalent in the treatment of patients with various types of advanced cancers; however, difficulties are still associated with predicting the outcomes of patients receiving ICIs due to heterogenous responses to these agents. OBJECTIVE: To develop a prognostic model for advanced cancer patients treated with ICIs. PATIENTS AND METHODS: This study retrospectively analyzed the impact of clinical parameters on overall survival (OS) in 329 patients with several advanced solid malignant tumors who received systemic therapy using ICIs. RESULTS: The primary tumors of 329 patients were as follows: lung (n = 89), kidney (n = 70), urinary tract (n = 52), skin (n = 50), stomach (n = 30), esophagus (n = 21), and head and neck (n = 17). Median OS after the introduction of ICIs was 17.3 months. Among the factors that correlated with OS in a univariate analysis, body mass index, C-reactive protein, hemoglobin, lymphocytes, and platelets were identified as independent predictors of OS in a multivariate analysis. Following the classification of patients into 3 groups based on positive numbers of these independent risk factors, median OS was not reached in the favorable risk group with 0 or 1 risk factor (n = 76), 19.5 months in the intermediate-risk group with 2 or 3 risk factors (n = 182), and 7.2 months in the poor risk group (n = 71) with 4 or 5 risk factors. CONCLUSIONS: Although this is a simple and objective model, it may be used as a reliable tool to predict the outcomes of advanced cancer patients receiving ICIs across multiple tumor types.
