RESUMO

Neuroendocrine prostate cancer (NEPC) is a histological variant of prostate cancer and is characterized by aggressiveness and poor clinical outcomes. NEPC usually develops as a mechanism of treatment resistance in patients receiving hormone therapy for advanced prostate cancer. NEPC is sensitive to primary platinum-based chemotherapy, and has a short response duration. Second-line therapy is required in many cases, but clinical data on subsequent treatment after progression to first-line chemotherapy is limited. Here we report our experience of four cases of NEPC treated with second-line chemotherapy. Progression-free and overall survival rates were very low in three of the patients. One patient received multidisciplinary therapy using systemic and local chemotherapy and radiation therapy and survived for 24 months after initiation of second-line chemotherapy. Multidisciplinary therapy with chemotherapy and radiation is a promising option for improving the survival of patients with NEPC.

RESUMO

OBJECTIVES: We clarified the effect of concomitant proton pump inhibitor use on oncological outcomes in patients with advanced urothelial carcinoma treated either with chemotherapy or immune checkpoint inhibitor. METHODS: We retrospectively reviewed patients with advanced urothelial carcinoma who received paclitaxel-gemcitabine therapy or pembrolizumab after platinum-based chemotherapy. The patients were divided into four groups based on the treatment regimen and the concomitant use of proton pump inhibitor. We compared survival outcomes between the groups and determined which factors predicted overall survival. RESULTS: Among the 60 and 75 patients treated with paclitaxel-gemcitabine and pembrolizumab, 15 and 29 used a concomitant proton pump inhibitor. Progression-free and overall survival was significantly shorter in patients who were administered pembrolizumab with concomitant proton pump inhibitor compared to those without. The use of a concomitant proton pump inhibitor had no effect on survival outcomes in patients who received paclitaxel-gemcitabine therapy. Furthermore, progression-free and overall survival were significantly shorter in patients treated with paclitaxel-gemcitabine therapy compared to those treated with pembrolizumab among patients without concomitant proton pump inhibitor. In contrast, there was no difference in survival outcomes between the two regimens among patients with concomitant proton pump inhibitor. Concomitant proton pump inhibitor use was associated with poor overall survival only in patients treated with pembrolizumab. CONCLUSION: The use of a concomitant proton pump inhibitor use had no impact on oncological outcomes in patients with advanced urothelial carcinoma treated with paclitaxel-gemcitabine therapy, different from those treated with pembrolizumab.

RESUMO

We introduced the da Vinci Xi surgical system (Intuitive Surgical G.K. CA) in January 2018, and here we report clinical statistics on outpatients, inpatients, and surgical procedures for the 3-year period from January 2017 to December 2019. The number of new outpatients since 2017 has remained almost unchanged at 1,406, 1,530, and 1,494 per year. There was an increasing trend in the number of inpatients, from 862 to 1,021 to 1,239. The main diseases of the inpatients over the 3-year period were bladder cancer in 676 (21.7%), renal cancer in 374 (12.0%), prostate cancer in 268 (8.6%), and urolithiasis in 263 (8.4%). The total number of surgeries in the three years was 1,931. The numbers of transurethral surgeries and laparoscopic surgeries, including robotic surgeries, were 1,063 (55.0%) and 396 (20.5%), respectively. The numbers of inpatients and surgery have been increasing year by year. Medical resources are limited and need to be distributed more efficiently.

RESUMO

OBJECTIVES: To evaluate the efficacy and tolerability of paclitaxel and gemcitabine therapy after platinum-based chemotherapy for patients with advanced urothelial carcinoma. METHODS: Consecutive patients with advanced urothelial carcinoma who received paclitaxel and gemcitabine therapy from December 2003 to March 2018 were retrospectively reviewed. The objective response for paclitaxel and gemcitabine therapy, progression-free survival and overall survival, and adverse events were evaluated. The reduction rate among each metastatic site and the associations between the clinical parameters and overall survival or progression-free survival were also assessed. RESULTS: We enrolled 58 patients. Complete and partial responses were observed in two (3.4%) and 15 patients (26%), respectively. The median progression-free survival and overall survival were 4.3 months (95% confidence interval 2.9-5.2) and 11.5 months (95% confidence interval 7.7-14.8), respectively. The objective response rates of primary site and metastases in lymph nodes, lung, bone, and liver were 6.0%, 37%, 23%, 0%, and 22%, respectively. Poor performance status (≥1), prior use of gemcitabine and the number of metastatic sites (≥2) were significantly associated with poor overall survival. Although three patients discontinued the treatment because of adverse events, there was no therapy-related death. CONCLUSIONS: Paclitaxel and gemcitabine therapy seems to be a valid option as a subsequent treatment after platinum-based chemotherapy for urothelial carcinoma, especially in patients with favorable performance status and no prior use of gemcitabine.

RESUMO

The oncological benefit of pelvic lymph node dissection (PLND) is still debatable because data on clinical outcomes of radical prostatectomy (RP) without PLND are lacking. In this study, we reported oncological outcome in consecutive 146 patients who underwent RP without PLND. Although 27% of our patients developed biochemical recurrence, the estimated 5-year overall survival rates were 100%, 96.3%, and 95.7% in the low-, intermediate-, and high-risk groups, respectively. These data in our patients were not inferior to those in previous reports that investigated the survivals in patients who received PLND during RP. The therapeutic significance of PLND should be re-evaluated.

RESUMO

BACKGROUND: In the present study, we examined the trends of premature mortality due to kidney and bladder cancers among the Japanese population from 1980 through 2010. METHODS: Mortality data were obtained from the World Health Organization mortality database. Years of life lost (YLL) was estimated using Japanese life tables. Average lifespan shortened (ALSS) was calculated and defined as the ratio of years of life lost relative to the expected lifespan. RESULTS: Over the study period, the age-standardized rates to the World Standard Population for deaths from kidney and bladder cancers were stable. The average years of life lost (AYLL) measure shows decreases of about 4 and 6 years of life for kidney cancer in men and women, respectively, and decreases of about 2 years of life for bladder cancer in both sexes. The ALSS shows that patients with kidney cancer lost 21.0% and 24.7% of their lifespan among men and women in 1980, whereas respective losses were 15.3% and 15.8% in 2010. Also, patients with bladder cancer on average lost 13.5% in men and 14.2% in women in 1980 and 10.8% in men and 11.1% in women in 2010. CONCLUSIONS: Our study shows favorable trends in premature mortality for kidney and bladder cancers in Japan over a 30-year period; however, patients with bladder cancer on average lost a smaller proportion of their lifespan compared to those with kidney cancer. The development of a novel ALSS measure is convenient in examination of the burden of premature mortality over time.

RESUMO

We conducted a review of the literature to identify the clinical benefits of pelvic lymph node dissection (PLND) during radical prostatectomy for clinically localized prostate cancer. The most recent guidelines recommend PLND, particularly extended PLND, during radical prostatectomy for localized prostate cancer. PLND is undoubtedly the most accurate method for nodal staging, and most patients, particularly those with high-risk cancer, are likely to undergo PLND during radical prostatectomy. Although many retrospective studies have assessed oncologic outcomes after PLND, its therapeutic benefit remains controversial. Patients with positive node(s) often have other more common unfavorable prognostic factors, such as seminal vesicle invasion, extra-prostatic extension, and positive surgical margins. Oncologic outcomes in patients who have not undergone PLND and those who have undergone PLND are almost identical. If an effective standard adjuvant therapy after prostatectomy is defined, the nodal status may be important and valuable. However, adjuvant treatment strategies for patients with a positive node have not been identified thus far. Therefore, determining the nodal status at surgery may not provide therapeutic benefit. PLND requires additional surgical time and is associated with several complications. Therefore, the indication for PLND should be considered carefully until well-designed prospective randomized trials establish high-quality clinical evidence.

RESUMO

There are few data on Bacillus Calmette-Guérin (BCG) therapy for upper urinary tract carcinoma in situ (UUT CIS). We retrospectively evaluated the efficacy and tolerability of BCG therapy for 41 patients [52 renal units(RUs)] with UUT CIS. Of 52 RUs, complete response was achieved in 47 (90%). The 5-year recurrence-, progression-free survival rates were 60.2% and 74.2%, respectively. Adverse events were observed in 31 (76%) patients, but most of them were mild. The scheduled instillations were completed in 31 (74%) of 42 patients. Our results demonstrated that BCG therapy for UUT CIS was satisfactory with high efficacy and tolerability.

RESUMO

The prognostic value of squamous differentiation (SD) in urothelial carcinoma (UC) of the bladder is unclear. The aim of this study was to identify the clinical significance of SD in UC in terms of oncological outcomes in patients undergoing radical cystectomy (RC). We evaluated consecutive patients with muscle-invasive bladder cancer (MIBC; clinical T2-4aN0M0) treated with RC at our institution from March 2003 to March 2017. We enrolled 20 and 81 patients with UC with SD (UCSD) and pure UC, respectively. Postoperative survival outcomes were compared between the patients with UCSD and pure UC using the Kaplan-Meier method. Pre- and postcystectomy factors that influenced the overall survival (OS) and recurrence-free survival (RFS) were investigated in these patients. Multivariate Cox regression models were used to identify the predictors of OS and RFS. With a median follow-up time of 31 months, the 5-year OS rate of the UCSD and pure UC groups was 41.1% and 69.7% ( P = .002) and the 5-year RFS rate was 51.8% and 59.5% ( P = .027), respectively. The shape of the Kaplan-Meier curves for UCSD suggested a more rapid course of the disease within the first 2 years than observed in pure UC. Multivariate analyses suggested that SD in UC was significantly associated with OS (hazard ratio [HR]: 4.22; 95% confidence interval [CI]: 1.20-14.8; P = .024) and close to significance for a lower RFS (HR: 2.13, 95% CI: 0.74-6.15, P = .064). Our results indicate that SD may be an independent predictor of OS and RFS in UC of MIBC in patients undergoing RC.

RESUMO

BACKGROUND/AIM: In recent years, switch maintenance after platinum-based chemotherapy has been a standard of care. However, the appropriate number of systemic chemotherapy cycles against advanced-stage urothelial carcinoma (UC) remains unclear. This study assessed the survival outcomes of first-line platinum-based chemotherapy according to treatment cycles in patients with metastatic disease. PATIENTS AND METHODS: We retrospectively evaluated patients with metastatic bladder and upper urinary tract cancer who received platinum-based combination therapy. Overall survival (OS) was evaluated using the Kaplan-Meier method and the log-rank test. RESULTS: Of 179 patients, 47 (26.3%) were women, and 73 (40.8%) had upper urinary tract cancer. Furthermore, 47 (26.3%) who were not eligible for cisplatin received carboplatin. The median number of treatment cycles was 3 (range=1-14 cycles). The rates of progressive disease within two cycles, from two to four cycles, and from four to six cycles were 18.4%, 19.2%, and 30.6%, respectively. The median OS of patients with 2, 3, 4, 5-6, and ≥7 treatment cycles were 8.6, 14.3, 21.3, 24.4, and 26.1 months, respectively. The OS did not significantly differ between patients receiving four treatment cycles and those receiving ≥5 treatment cycles. In patients with disease control (complete or partial response or stable disease) receiving ≥4 treatment cycles, there was no significant difference in terms of OS between patients receiving four cycles and those receiving six cycles. CONCLUSION: Four cycles of first-line platinum-based chemotherapy can be effective in patients with metastatic UC.

RESUMO

BACKGROUND/AIM: The association between clinical outcomes and posttreatment changes in the neutrophil-to-lymphocyte ratio (NLR) and neutrophil-to-eosinophil ratio (NER) in patients receiving avelumab maintenance therapy for advanced urothelial carcinoma (UC) is unclear. PATIENTS AND METHODS: We retrospectively analyzed data from advanced UC patients who received avelumab and had not progressed with first-line platinum-based chemotherapy. The association between the changes in NLR and NER from pretreatment to week 6 of avelumab treatment and therapeutic efficacy was evaluated. RESULTS: Thirty-two patients were enrolled in this study (male, n=25; female, n=7; median age, 71 years). At six weeks, 19 patients (59.4%) had a decreased NLR and 18 patients (56.3%) had a decreased NER. When the change in NER from pretreatment to six weeks was compared, there was a significant decrease in responders (without progressive disease) (p=0.008); however, there was no significant decrease in non-responders (progressive disease) (p=0.855). The NLR showed no significant change in either group (p=0.099, 0.358). When patients were compared according to the change in the NLR at six weeks, progression-free survival (PFS) and overall survival (OS) did not differ between the decreased NLR and increased NLR groups (p=0.116, 0.256). When patients were compared according to the change in the NER, the decreased and increased groups showed significant differences in PFS and OS (p<0.001, 0.030). CONCLUSION: In the present real-world study, the responders showed a significantly decreased NER at six weeks. This was associated with improved PFS and OS in patients with advanced UC.

RESUMO

BACKGROUND/AIM: Variant urothelial carcinoma (VUC, defined herein as urothelial carcinoma with any histological variant) is frequently observed at an advanced stage. However, the efficacy of systemic chemotherapy against VUC in metastatic disease has rarely been reported. This study assessed the therapeutic response and survival outcomes of platinum-based chemotherapy as first-line treatment in patients with metastatic VUC. PATIENTS AND METHODS: We retrospectively analyzed consecutive patients with metastatic bladder and upper urinary tract cancer who received gemcitabine plus cisplatin (or carboplatin) at the University of Occupational and Environmental Health Hospital between November 2008 and November 2022. Progression-free survival and overall survival were evaluated using the Kaplan-Meier method and Cox proportional hazard models. RESULTS: Out of 131 patients recorded, 86 (65.6%) had pure urothelial carcinoma (PUC) and 45 (34.4%) had VUC. The most common variant element was squamous differentiation (44.4%). Compared to those with PUC, patients with VUC showed a comparable objective response rate (33.3% vs. 41.9%, p=0.451) and disease control rate (64.5% vs. 75.6%, p=0.221). They also had poorer progression-free survival (median=4.9 months vs. 7.9 months, p=0.014) and overall survival (median=10.9 months vs. 18.2 months, p=0.037) than those with PUC. On multivariate analysis, VUC was an independent predictor of progression (hazard ratio=1.79; 95% confidence interval=1.19-2.69; p=0.005) and mortality (hazard ratio=1.64; 95% confidence interval=1.08-2.48; p=0.020). CONCLUSION: Although the response of metastatic VUC to platinum-based chemotherapy was not inferior to that of PUC, VUC had progressed faster than PUC. VUC was significantly associated with a poor prognosis after platinum-based chemotherapy as first-line treatment.

RESUMO

Subtype of urothelial carcinoma (SUC), defined here as urothelial carcinoma with any histologic subtype or divergent differentiation, is a clinically aggressive disease. However, the efficacy of enfortumab vedotin (EV) against SUC remains unclear. Hence, this study aimed to assess the oncological outcomes of patients with SUC treated with EV for metastatic disease. We retrospectively evaluated consecutive patients with advanced lower and upper urinary tract cancer who received EV after platinum-based chemotherapy and immune checkpoint blockade therapy at six institutions. The objective response rate (ORR), progression-free survival (PFS), and overall survival (OS) were compared between patients with pure urothelial carcinoma (PUC) and those with SUC. We identified 44 and 18 patients with PUC and SUC, respectively. Squamous differentiation was the most common subtype element, followed by glandular differentiation and sarcomatoid subtype. Although patients with SUC had a comparable ORR to those with PUC, the duration of response for SUC was short. Patients with SUC had poorer PFS than those with PUC; however, no significant difference was observed in OS. Multivariate analysis revealed that SUC was significantly associated with shorter PFS. Although the response of metastatic SUC to EV was similar to that of PUC, SUC showed faster progression than PUC.

RESUMO

BACKGROUND/AIM: The clinical outcomes associated with cutaneous toxicity and changes in the renal function of patients receiving enfortumab vedotin (EV) for advanced urothelial carcinoma (UC) is unclear. PATIENTS AND METHODS: We retrospectively analyzed the relationship between clinical outcomes and EV-related cutaneous toxicity, and the influence on the renal function in 58 patients with advanced UC who received EV after the failure of platinum-based chemotherapy and immune checkpoint inhibitors from December 2021 to July 2023. RESULTS: There were no differences in the overall response and disease control rates between patients with any grade of EV-related cutaneous toxicity and without (p=0.605 and p>0.99, respectively) nor of grade ≥3 (p>0.99 and p=0.173, respectively). Progression-free survival was not significantly associated with EV-related cutaneous toxicity of any grade (5.4 vs. 5.6 months, p=0.557) nor of grade ≥3 (2.7 vs. 5.6 months, p=0.053). Overall survival was not significantly associated with EV-related cutaneous toxicity of any grade (11.8 vs. 8.9 months, p=0.389), nor of grade ≥3 (4.6 vs. 11.4 months, p=0.168). The incidence of EV-related cutaneous toxicity of any grade was significantly higher in patients with any grade of ICI-related cutaneous toxicity (88.9% vs. 36.7%, p=0.008). There was no significant difference in the serum creatinine levels after EV treatment (p=0.211). Divided into two groups according to their renal function, using a serum creatinine cut-off of 2 mg/dl, there were no significant changes after EV treatment in either group (p=0.187 and p=0.938). CONCLUSION: EV-related cutaneous toxicity did not affect clinical outcomes, although it occurred in patients who experienced immune checkpoint inhibitor-related cutaneous toxicity. EV did not affect renal function.

RESUMO

BACKGROUND/AIM: Hyaluronic acid (HA) is a large glycosaminoglycan composed of an extracellular matrix. The HA-rich microenvironment and receptors of HA have been suggested to play roles in cancer progression. The biological and clinical significance of receptor for HA-mediated motility (RHAMM), known as CD168 in prostate cancer (PC) remains unknown. This study aimed to investigate the expression of RHAMM, as well as its functional and clinical relevance in PC. MATERIALS AND METHODS: HA concentration and RHAMM mRNA expression were examined in 3 PC cell lines (LNCaP, PC3 and DU145). We investigated the effect of HA and RHAMM on the migratory ability of PC cells using a transwell migration assay. Immunohistochemistry was also used to evaluate the RHAMM expression pattern in pre-treatment tissue samples from 99 patients with metastatic hormone-sensitive PC (HSPC) who received androgen deprivation therapy (ADT). RESULTS: HA was secreted in all cultured PC cell lines. Among the total HA, low-molecular-weight HA (LMW-HA) (<100 kDa) was detected all examined cell lines. The number of migration cells was significantly increased by adding LMW-HA. RHAMM mRNA expression was increased in DU145 cells. Knockdown of RHAMM using small-interfering RNA resulted in decreased cell migration. Immunohistochemical analysis revealed strong RHAMM expression in 31 (31.3%) patients with metastatic HSPC. A strong RHAMM expression was significantly associated with short ADT duration and poor survival in univariate and multivariate analyses. CONCLUSION: The size of HA is important in terms of PC progression. LMW-HA and RHAMM enhanced PC cell migration. RHAMM could be used as a novel prognostic marker in patients with metastatic HSPC.

RESUMO

Neuroendocrine prostate cancer (NEPC) is generally an aggressive form of prostate cancer that can arise de novo or develop as a castration-resistant mechanism. While first-line platinum-based chemotherapy is effective against NEPC, its limited response duration and subsequent treatments pose significant clinical challenges. Standard second-line treatments have not been established due to the limited data available. The aim of this review was to reveal the current status of second-line therapy for NEPC. A literature search was conducted using PubMed and Web of Science and a total of 13 articles were included in this review. Prospective and retrospective studies demonstrated that treatment outcome of second-line therapy using platinum with etoposide or docetaxel was unfavorable and progression-free survival was 3 months or shorter. Amrubicin and irinotecan were also frequently used as second-line therapy, however, efficacy of these agents was modest and response duration was less than 6 months. NEPC patients with homologous recombination repair gene alterations may benefit from treatment with poly (ADP-ribose) polymerase (PARP) inhibitors. Ongoing clinical studies investigate various agents, including immune checkpoint inhibitors, molecularly targeted agents, and PARP inhibitors. With the increasing recognition and active biopsy of NEPC lesions, the number of NEPC patients is anticipated to rise. Accumulating more knowledge and experience is crucial in developing novel treatment strategies to combat this disease.

RESUMO

BACKGROUND/AIM: The organ-specific therapeutic effects of avelumab for the maintenance treatment of advanced urothelial carcinoma (UC) are unclear. PATIENTS AND METHODS: Patients who received avelumab for advanced UC that had not progressed with first-line platinum-based chemotherapy and who had measurable disease were retrospectively analyzed. The organ-specific response was evaluated, and progression-free survival (PFS) and overall survival (OS) were estimated. RESULTS: We analyzed 42 patients (male, n=31; median age, 72 years). The overall response rate [complete response (CR)+ partial response (PR)] and disease control rate (CR+PR+stable disease) were 2.4% and 47.6%, respectively. In total, 27, 11, 8 and 5 patients had measurable lymph node [organ-specific response rate (OSRR) 7.4%, organ-specific disease control rate (OSDCR) 59.3%], lung (OSRR 18.2%, OSDCR 36.4%), primary tumor organ (OSRR 0%, OSDCR 100%) and liver (OSRR 0%, OSDCR 100%) disease, respectively. The median PFS and OS was 3.8 months and 20.2 months, respectively. Regarding organ-specific PFS, a log-rank test confirmed significant differences between patients with and without primary tumor organ disease (p=0.009) and patients with and without liver metastasis (p=0.015). Regarding organ-specific OS, a log-rank test revealed no significant differences between patients with and without metastatic disease for all organs (lung: p=0.835; lymph node: p=0.914; bone: p=0.257; primary tumor: p=0.057; liver: p=0.893). CONCLUSION: In patients receiving avelumab maintenance therapy, no significant differences in OS were observed between patients with and without metastasis to any organ, including the primary organ, although metastases and the primary tumor organ disease showed different responses.

RESUMO

BACKGROUND/AIM: This study retrospectively investigated the impact of enfortumab vedotin (EV) monotherapy on the oncological outcome, safety profile, and health-related quality of life (HRQoL) in patients with metastatic urothelial carcinoma. PATIENTS AND METHODS: We assessed 26 consecutive patients who had received EV monotherapy after failure of platinum-based chemotherapy and immune checkpoint blockade therapy at our single institution from December 2021 to January 2023. The objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), overall survival (OS), incidence of adverse events (AEs), and EORTC QLQ-C30 as an HRQoL instrument were evaluated. RESULTS: The ORR and DCR were 57.7% and 80.8%, respectively. EV was effective regardless of the patient and tumor characteristics, including the efficacy of previous systemic therapy, performance status, number of Bellmunt risk factors, and presence of variant histology. With a median follow-up time of 7.5 months, the median durations of PFS and OS were 5.4 months and 10.3 months, respectively. Grade ≥3 AEs included neutropenia (15.4%), fatigue (7.7%), appetite loss (7.7%), rash (3.8%), febrile neutropenia (3.8%), hyperglycemia (3.8%), and interstitial pneumonia (3.8%). AEs resulting in withdrawal of EV, interruption of EV, and dose reduction occurred in two (7.7%), nine (34.6%), and 13 patients (50.0%), respectively. The EORTC QLQ-C30 scores from baseline to post-EV introduction remained stable. CONCLUSION: EV monotherapy demonstrated promising anti-tumor activity and tolerability in patients with metastatic urothelial carcinoma.

RESUMO

BACKGROUND/AIM: We aimed to clarify the association between body mass index (BMI) and clinical outcomes of pembrolizumab treatment for advanced urothelial cancer (UC). PATIENTS AND METHODS: We retrospectively reviewed the records of patients with advanced UC who received pembrolizumab after chemotherapy between March 2018 and December 2021. Patients were divided according to BMI into the non-overweight group (BMI <25 kg/m2) and the overweight group (BMI ≥25 kg/m2). We compared the two groups' tumour response, survival rates, and incidence of immune-related adverse events (irAEs) and investigated the factors predicting survival. RESULTS: Of 84 eligible patients, 63 (75%) and 21 (25%) were in the non-overweight and overweight groups, respectively. Although the objective response rate was higher in the overweight group (55%) than that in the non-overweight group (29%), the difference was not significant. Progression-free survival (PFS) was significantly longer in the overweight group (median 15.2 months) than that in the non-overweight group (median 4.8 months; p=0.01). Overall survival was also longer in the overweight group (median 36.1 months) compared to that in the non-overweight group (13.4 months), but the difference was not significant (p=0.11). Multivariable analysis showed that overweight was significantly associated with favourable PFS. Any and severe (grade 3) irAEs were observed in 15 (24%) and 5 (7.9%) patients in the non-overweight group, respectively, and in 8 (38%) and 2 (9.5%) patients in the overweight group, respectively, but the differences were not significant. CONCLUSION: BMI was associated with oncological outcomes in patients with advanced UC who received pembrolizumab but not with the development of irAEs.

RESUMO

BACKGROUND/AIM: The association of clinical outcomes with posttreatment persistent changes in eosinophils and other white blood cell (WBC) subtypes in patients with advanced urothelial cancer (UC) treated with pembrolizumab after the failure of platinum-based chemotherapy is unclear. PATIENTS AND METHODS: We retrospectively analyzed 87 patients with advanced UC who received pembrolizumab after the failure of platinum-based chemotherapy. The changes in WBC subtypes from pretreatment were evaluated three and six weeks after pembrolizumab administration. The association between the changes in the WBC subtypes and clinical outcomes was then evaluated using the Kaplan-Meier method and a Cox regression model. RESULTS: Among WBC subtypes, significant changes in the absolute (AEC) and relative eosinophil count (REC) and the neutrophil-to-eosinophil ratio (NER) were observed at three and six weeks compared with pretreatment (p<0.001). Multivariable Cox regression analyses revealed that a persistent decrease in AEC and REC and a persistent increase in NER were associated with poor overall survival. CONCLUSION: Persistent increase in AEC and REC and decrease in NER in the early phase after pembrolizumab may be significant early predictive markers of improved clinical outcomes in patients with advanced UC receiving pembrolizumab.
