ABSTRACT

Cretostimogene grenadenorepvec is a serotype-5 oncolytic adenovirus designed to selectively replicate in cancer cells with retinoblastoma pathway alterations, previously tested as monotherapy in bacillus Calmette-Guérin (BCG)-experienced non-muscle-invasive bladder cancer. In this phase 2 study, we assessed the potential synergistic efficacy between intravesical cretostimogene and systemic pembrolizumab in patients with BCG-unresponsive non-muscle-invasive bladder cancer with carcinoma in situ (CIS). Thirty-five patients were treated with intravesical cretostimogene with systemic pembrolizumab. Induction cretostimogene was administered weekly for 6 weeks followed by three weekly maintenance infusions at months 3, 6, 9, 12 and 18 in patients maintaining complete response (CR). Patients with persistent CIS/high-grade Ta at the 3-month assessment were eligible for re-induction. Pembrolizumab was administered for up to 24 months. The primary endpoint was CR at 12 months as assessed by cystoscopy, urine cytology, cross-sectional imaging and mandatory bladder mapping biopsies. Secondary endpoints included CR at any time, duration of response, progression-free survival and safety. The CR rate in the intention-to-treat population at 12 months was 57.1% (20 out of 35, 95% confidence interval (CI) 40.7-73.5%), meeting the primary endpoint. A total of 29 out of 35 patients (82.9%, 95% CI 70.4-95.3%) derived a CR at 3 months. With a median follow-up of 26.5 months, the median duration of response has not been reached (95% CI 15.7 to not reached). The CR rate at 24 months was 51.4% (18 out of 35) (95% CI 34.9-68.0%). No patient progressed to muscle-invasive bladder cancer in this trial. Adverse events attributed to cretostimogene were low grade, self-limiting and predominantly limited to bladder-related symptoms. Immune-related adverse effects were exclusively associated with pembrolizumab. A total of 5 out of 35 patients (14.3%) developed grade 3 treatment-related adverse effects, all related to pembrolizumab. There was no evidence of overlapping or synergistic toxicities. Combination intravesical cretostimogene and systemic pembrolizumab demonstrated enduring efficacy. With a toxicity profile similar to its monotherapy components, this combination may shift the benefit-to-risk ratio for patients with BCG-unresponsive CIS.

ABSTRACT

Background and objective: Patients with intermediate-risk non-muscle-invasive bladder cancer (IR NMIBC) have a high risk of recurrence and need effective therapies to reduce the risk of disease recurrence or progression. This phase 1b study (NCT02720367) assessed the safety and tolerability of TAR-200, an intravesical drug delivery system, in participants with IR NMIBC. Methods: Participants with recurrent IR NMIBC were eligible. Participants received either two 7-d or two 21-d TAR-200 dosing cycles over a 4-6-wk period in a marker lesion/ablation design. TAR-200 was placed in the window between the cystoscopy showing recurrent papillary disease and the subsequent complete transurethral resection of the bladder tumour. The primary endpoint was TAR-200 safety. The secondary endpoints included TAR-200 tolerability, pharmacokinetics, and preliminary efficacy. Key findings and limitations: Twelve participants received TAR-200 treatment. No TAR-200-related serious or grade ≥ 3 treatment-emergent adverse events (TEAEs) occurred. Nine participants had grade ≤ 2 TAR-200-related TEAEs, with urgency, dysuria, and haematuria being most common. Two participants refused a second dosing cycle due to urinary urgency and frequency. Insertion and removal of TAR-200 was successful in all cases. Plasma gemcitabine concentrations remained below the lower limit of detection. Five participants (42%) had complete response (CR): four had pathological CR and one had CR based on visual assessment. Conclusions and clinical implications: TAR-200 appears to be safe and well tolerated, with encouraging preliminary efficacy in participants with IR NMIBC. This study lays the groundwork for the multiple phase 2 and 3 global studies that are currently on-going for TAR-200. Patient summary: In this study, researchers evaluated the safety of the novel drug delivery system TAR-200 in participants with intermediate-risk non-muscle-invasive bladder cancer. They concluded that TAR-200 was safe and well tolerated with promising antitumour activity.

ABSTRACT

PURPOSE: Half of patients with muscle-invasive bladder cancer worldwide may not receive curative-intent therapy. Elderly or frail patients are most affected by this unmet need. TAR-200 is a novel, intravesical drug delivery system that provides sustained, local release of gemcitabine into the bladder over a 21-day dosing cycle. The phase 1 TAR-200-103 study evaluated the safety, tolerability, and preliminary efficacy of TAR-200 in patients with muscle-invasive bladder cancer who either refused or were unfit for curative-intent therapy. MATERIALS AND METHODS: Eligible patients had cT2-cT3bN0M0 urothelial carcinoma of the bladder. TAR-200 was inserted for 4 consecutive 21-day cycles over 84 days. The primary end points were safety and tolerability at 84 days. Secondary end points included rates of clinical complete response and partial response as determined by cystoscopy, biopsy, and imaging; duration of response; and overall survival. RESULTS: Median age of the 35 enrolled patients was 84 years, and most were male (24/35, 68.6%). Treatment-emergent adverse events related to TAR-200 occurred in 15 patients. Two patients experienced treatment-emergent adverse events leading to removal of TAR-200. At 3 months, complete response and partial response rates were 31.4% (11/35) and 8.6% (3/35), respectively, yielding an overall response rate of 40.0% (14/35; 95% CI 23.9-57.9). Median overall survival and duration of response were 27.3 months (95% CI 10.1-not estimable) and 14 months (95% CI 10.6-22.7), respectively. Progression-free rate at 12 months was 70.5%. CONCLUSIONS: TAR-200 was generally safe, well tolerated, and had beneficial preliminary efficacy in this elderly and frail cohort with limited treatment options.

ABSTRACT

OBJECTIVES: Neoadjuvant chemotherapy and radical cystectomy (RC) are underutilized standards of care for the treatment of muscle-invasive bladder cancer (MIBC) due to high patient burden from systemic toxicities and postoperative complications, respectively. TAR-200 is a novel intravesical drug delivery system developed to release gemcitabine into the bladder urine continuously, resulting in distribution of drug into stromal layers of the bladder. The primary aim of the TAR-200-101 study was to evaluate the safety of TAR-200 in patients with MIBC prior to RC (NCT02722538). METHODS AND MATERIALS: This phase I, open-label study was conducted across 6 US and European sites. Eligible patients were aged ≥18 years with histologically confirmed T2a-T3b N0-N1 M0 urothelial cancer and had refusal or were ineligible to receive cisplatin-based combination chemotherapy. Two arms were enrolled serially. Patients in Arm 1 had residual tumor >3 cm after transurethral resection of bladder tumor (TURBT); those in Arm 2 had undergone maximal TURBT (residual tumor <3 cm). Patients received two 7-day cycles of intravesical gemcitabine delivery via TAR-200 before undergoing RC. Primary outcome was safety; secondary outcomes were tolerability, pharmacokinetics, and preliminary efficacy. RESULTS: Of 23 patients in the intention-to-treat population (11 in Arm 1, 12 in Arm 2), 20 completed both dosing cycles of TAR-200. No patients were classified as intolerant to TAR-200. Ten patients (4 in Arm 1, 6 in Arm 2) experienced ≥1 treatment-emergent adverse events (TEAEs). The most common TAR-200-related TEAEs were pollakiuria (n = 3) and urinary incontinence (n = 2). All TEAEs prior to RC were grade ≤2; 1 patient in Arm 2 experienced a grade 3 non-treatment-related TEAE. Plasma gemcitabine levels were undetectable. In Arm 1, those with residual tumor, 4 of 10 patients exhibited pathologic downstaging; 1 experienced a complete response (CR) and 3 a partial response (PR). In Arm 2, those undergoing maximal TURBT, 6 of 10 patients exhibited downstaging; 3 experienced a CR and 3 a PR. CONCLUSION: Controlled intravesical gemcitabine release via TAR-200 was safe and well tolerated in patients with MIBC.

ABSTRACT

BACKGROUND: Earlier studies on the cost of muscle-invasive bladder cancer treatments are limited to short-term costs of care. We determined the 2- and 5-year costs associated with trimodal therapy (TMT) vs. radical cystectomy (RC). METHODS: We performed a retrospective cohort study using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. Total Medicare costs at 2 and 5 years following RC vs. TMT were compared using inverse probability of treatment-weighted propensity score models. RESULTS: A total of 2,537 patients aged 66 to 85 years were diagnosed with clinical stage T2-4a muscle-invasive bladder cancer. Total median costs for patients that received no definitive treatment(s) were $73,780 and $88,275 at 2-and 5-years. Costs were significantly higher for TMT than RC at 2-years ($372,839 vs. $191,363, Median Difference $127,815, Hodges-Lehmann Estimate (H-L) 95% Confidence Interval (CI), $112,663-$142,966) and 5-years ($424,570 vs. $253,651, Median Difference $124,466, H-L 95% CI, $105,711-$143,221). TMT had higher outpatient costs than RC (2-years: $318,221 vs. $100,900; 5-years: $367,092 vs. $146,561) with significantly higher costs with radiology, medications, pathology/laboratory, and other professional services. RC had higher inpatient costs than TMT (2-years: $62,240 vs. $33,631, Median Difference $-29,174, H-L 95% CI, $-32,364-$-25,984; 5-years: $75,499 vs. $45,223, Median Difference $-29,843, H-L 95% CI, $-33,905-$-25,781). CONCLUSIONS AND RELEVANCE: The excess spending associated with trimodal therapy vs. radical cystectomy was largely driven by outpatient expenditures. The relatively high long-term trimodal therapy costs are prime targets for cost containment strategies to optimize future value-based care.

ABSTRACT

A recent phase 3 trial of intravesical nadofaragene firadenovec reported a promising complete response rate for patients with bacillus Calmette-Guérin-unresponsive non-muscle-invasive bladder cancer. This study examined the ability of antiadenovirus antibody levels to predict the durability of therapeutic response to nadofaragene firadenovec. A standardized and validated quantitative assay was used to prospectively assess baseline and post-treatment serum antibody levels among 91 patients from the phase 3 trial, of whom 47 (52%) were high-grade recurrence free at 12 mo (responders). While baseline titers did not predict treatment response, 3-mo titer >800 was associated with a higher likelihood of durable response (p = 0.026). Peak post-treatment titers >800 were noted in 42 (89%) responders versus 26 (59%) nonresponders (p = 0.001; assay sensitivity, 89%; negative predictive value, 78%). Moreover, 22 (47%) responders compared with eight (18%) nonresponders had a combination of peak post-treatment titers >800 and peak antibody fold change >8 (p = 0.004; assay specificity, 82%; positive predictive value, 73%). A majority of responders continued to have post-treatment antibody titers >800 after the first 6 mo of therapy. In conclusion, serum antiadenovirus antibody quantification may serve as a novel predictive marker for nadofaragene firadenovec response durability. Future studies will focus on large-scale validation and clinical utility of the assay. PATIENT SUMMARY: This study reports on a planned secondary analysis of a phase 3 multicenter clinical trial that established the benefit of nadofaragene firadenovec, a novel intravesical gene therapeutic, for the treatment of patients with bacillus Calmette-Guérin (BCG)-unresponsive high-risk non-muscle-invasive bladder cancer. Prospective assessment of serum anti-human adenovirus type-5 antibody levels of patients in this trial indicated that a combination of post-treatment titers and fold change from baseline can predict treatment efficacy. While this merits additional validation, our findings suggest that serum antiadenovirus antibody levels can serve as an important predictive marker for the durability of therapeutic response to nadofaragene firadenovec.

ABSTRACT

OBJECTIVES: To investigate the relationship between gender, body mass index (BMI), and prognosis in renal cell carcinoma (RCC) patients. MATERIALS AND METHODS: We retrospectively reviewed 1353 patients with RCC who underwent a partial or radical nephrectomy between 1988 and 2015. The association among sex, BMI, stage, grade, overall survival (OS), and recurrence-free survival (RFS) was analyzed. RESULTS: The median age of the patients was 59.4 ± 11.9 years. Female patients had proportionally lower grade tumors than male patients (Grade I-II in 75.5% vs. 69.3% in women and men, respectively, P = 0.022). There was no relationship between Fuhrman grade and BMI when substratified by gender (p > 0.05). There was a nonsignificant trend toward more localized disease in female patients (p = 0.058). There was no relationship between T stage and BMI when stratified by gender (p > 0.05). Patients with higher BMI had significantly better OS (p = 0.0004 and P = 0.0003) and RFS (P = 0.0209 and P =0.0082) whether broken out by lower 33rd or 25th percentile. Male patients with higher BMI had significantly better OS and RFS rates. However, there was no relationship between BMI and OS or RFS for female patients (P > 0.05). Multivariate analysis of the entire cohort demonstrated that a BMI in the lower quartile independently predicts OS (hazard ratio 1.604 [95% confidence interval: 1.07-2.408], P = 0.022) but not RFS (P > 0.05). When stratified by gender, there was no relationship between BMI and either OS or RFS (P > 0.05). CONCLUSIONS: Increasing BMI was associated with RCC prognosis. However, the clinical association between BMI and oncologic outcomes may be different between men and women.

ABSTRACT

INTRODUCTION: To assess and improve quality of care, the Commission on Cancer developed 3 evidence-based quality measures for the treatment of muscle invasive bladder cancer. We sought to assess performance of these measures prior to their implementation, whether compliance was associated with survival and whether patient factors influenced compliance. METHODS: We assessed all patients 18 to 90 years old diagnosed with invasive, nonmetastatic bladder cancer between 2004 and 2015 using the National Cancer Database. Both univariable and multivariable analyses were utilized to determine the effect of compliance on survival and identify patient level predictors of compliance. RESULTS: Of the 46,502 patients identified 22,218 underwent surgical management and 5,282 received trimodal therapy. All quality measures were achieved in 45.7% of the surgical cohort, which was associated with lower all cause mortality (HR 0.89, 95% CI 0.85-0.93, p <0.01). Time less than 90 days to trimodal therapy was achieved in 35.0% and was not associated with lower all cause mortality (HR 0.93, 95% CI 0.85-1.01, p=0.07). In the surgical cohort compliance was associated with higher income (OR 1.27, 95% CI 1.13-1.46, p <0.01), living in a higher educated zip code area (OR 1.15, 95% CI 1.02-1.30, p=0.02) and living 10 or more miles from the place of treatment (OR 1.38, 95% CI 1.29-1.47, p <0.01). CONCLUSIONS: Quality measure compliance is associated with improved survival in patients undergoing surgical management of muscle invasive bladder cancer. Despite this benefit, achievement of all 3 metrics was observed in less than half of patients prior to quality measure implementation.

ABSTRACT

BACKGROUND: BCG is the most effective therapy for high-risk non-muscle-invasive bladder cancer. Nadofaragene firadenovec (also known as rAd-IFNa/Syn3) is a replication-deficient recombinant adenovirus that delivers human interferon alfa-2b cDNA into the bladder epithelium, and a novel intravesical therapy for BCG-unresponsive non-muscle-invasive bladder cancer. We aimed to evaluate its efficacy in patients with BCG-unresponsive non-muscle-invasive bladder cancer. METHODS: In this phase 3, multicentre, open-label, repeat-dose study done in 33 centres (hospitals and clinics) in the USA, we recruited patients aged 18 years or older, with BCG-unresponsive non-muscle-invasive bladder cancer and an Eastern Cooperative Oncology Group status of 2 or less. Patients were excluded if they had upper urinary tract disease, urothelial carcinoma within the prostatic urethra, lymphovascular invasion, micropapillary disease, or hydronephrosis. Eligible patients received a single intravesical 75 mL dose of nadofaragene firadenovec (3 × 1011 viral particles per mL). Repeat dosing at months 3, 6, and 9 was done in the absence of high-grade recurrence. The primary endpoint was complete response at any time in patients with carcinoma in situ (with or without a high-grade Ta or T1 tumour). The null hypothesis specified a complete response rate of less than 27% in this cohort. Efficacy analyses were done on the per-protocol population, to include only patients strictly meeting the BCG-unresponsive definition. Safety analyses were done in all patients who received at least one dose of treatment. The study is ongoing, with a planned 4-year treatment and monitoring phase. This study is registered with ClinicalTrials.gov, NCT02773849. FINDINGS: Between Sept 19, 2016, and May 24, 2019, 198 patients were assessed for eligibility. 41 patients were excluded, and 157 were enrolled and received at least one dose of the study drug. Six patients did not meet the definition of BCG-unresponsive non-muscle-invasive bladder cancer and were therefore excluded from efficacy analyses; the remaining 151 patients were included in the per-protocol efficacy analyses. 55 (53·4%) of 103 patients with carcinoma in situ (with or without a high-grade Ta or T1 tumour) had a complete response within 3 months of the first dose and this response was maintained in 25 (45·5%) of 55 patients at 12 months. Micturition urgency was the most common grade 3-4 study drug-related adverse event (two [1%] of 157 patients, both grade 3), and there were no treatment-related deaths. INTERPRETATION: Intravesical nadofaragene firadenovec was efficacious, with a favourable benefit:risk ratio, in patients with BCG-unresponsive non-muscle-invasive bladder cancer. This represents a novel treatment option in a therapeutically challenging disease state. FUNDING: FKD Therapies Oy.

ABSTRACT

INTRODUCTION: The treatment landscape for patients with metastatic hormone-sensitive prostate cancer (mHSPC) has changed dramatically in the past five years, despite little change in the preceding 20 years. Such rapid change can make it difficult for clinicians to remain abreast of the current literature and synthesize the relevant data to inform evidence-based treatment decisions. METHODOLOGY: We performed a narrative, comprehensive review of treatment options for patients with mHSPC as of December 31, 2019. Specifically, we focused on phase II and III randomized controlled trials assessing the role of chemotherapy, novel androgen axis targeting agents, local-(prostate) directed therapy, and metastasis-directed therapy. RESULTS: The data support a survival benefit with the addition of four different agents to androgen deprivation among men with newly diagnosed prostate cancer-docetaxel, abiraterone acetate, enzalutamide, and apalutamide. While not directly compared, the efficacy of these agents appears similar. That said, there are differences in their toxicity profiles and notable differences in cost between agents. Although analyses encompassing men with low- and high-volume metastases failed to demonstrate a significant survival benefit for radiotherapy treatment to the prostate, new data demonstrates a benefit for men with low-volume metastatic disease. Ongoing trials will assess whether this applies to local surgical treatment. Similarly, metastasis-directed therapy appears beneficial among carefully selected patients. CONCLUSION: Treatment options for patients with mHSPC are rapidly changing following years of stagnation. A number of systemic therapies offer benefit without significant clinical differences between them. The role for local treatment of the prostate as well as metastatic sites continues to evolve.

ABSTRACT

PURPOSE: Provide evidence- and expert-based recommendations for optimal use of imaging in advanced prostate cancer. Due to increases in research and utilization of novel imaging for advanced prostate cancer, this guideline is intended to outline techniques available and provide recommendations on appropriate use of imaging for specified patient subgroups. METHODS: An Expert Panel was convened with members from ASCO and the Society of Abdominal Radiology, American College of Radiology, Society of Nuclear Medicine and Molecular Imaging, American Urological Association, American Society for Radiation Oncology, and Society of Urologic Oncology to conduct a systematic review of the literature and develop an evidence-based guideline on the optimal use of imaging for advanced prostate cancer. Representative index cases of various prostate cancer disease states are presented, including suspected high-risk disease, newly diagnosed treatment-naïve metastatic disease, suspected recurrent disease after local treatment, and progressive disease while undergoing systemic treatment. A systematic review of the literature from 2013 to August 2018 identified fully published English-language systematic reviews with or without meta-analyses, reports of rigorously conducted phase III randomized controlled trials that compared ≥ 2 imaging modalities, and noncomparative studies that reported on the efficacy of a single imaging modality. RESULTS: A total of 35 studies met inclusion criteria and form the evidence base, including 17 systematic reviews with or without meta-analysis and 18 primary research articles. RECOMMENDATIONS: One or more of these imaging modalities should be used for patients with advanced prostate cancer: conventional imaging (defined as computed tomography [CT], bone scan, and/or prostate magnetic resonance imaging [MRI]) and/or next-generation imaging (NGI), positron emission tomography [PET], PET/CT, PET/MRI, or whole-body MRI) according to the clinical scenario.

ABSTRACT

BACKGROUND: To evaluate the impact of salvage therapy (ST) on overall survival (OS) in recurrent primary urethral cancer (PUC). PATIENTS: A series of 139 patients (96 men, 43 women; median age = 66, interquartile range: 57-77) were diagnosed with PUC at 10 referral centers between 1993 and 2012. The modality of ST of recurrence (salvage surgery vs. radiotherapy) was recorded. Kaplan-Meier analysis with log-rank was used to estimate the impact of ST on OS (median follow-up = 21, interquartile range: 5-48). RESULTS: The 3-year OS for patients free of any recurrence (I), with solitary or concomitant urethral recurrence (II), and nonurethral recurrence (III) was 86.5%, 74.5%, and 48.2%, respectively (P = 0.002 for I vs. III and II vs. III; P = 0.55 for I vs. II). In the 80 patients with recurrences, the modality of primary treatment of recurrence was salvage surgery in 30 (37.5%), salvage radiotherapy (RT) in 8 (10.0%), and salvage surgery plus RT in 5 (6.3%) whereas 37 patients did not receive ST for recurrence (46.3%). In patients with recurrences, those who underwent salvage surgery or RT-based ST had similar 3-year OS (84.9%, 71.6%) compared to patients without recurrence (86.7%, P = 0.65), and exhibited superior 3-year OS compared to patients who did not undergo ST (38.0%, P<0.001 compared to surgery, P = 0.045 to RT-based ST, P = 0.29 for surgery vs. RT-based ST). CONCLUSIONS: In this study, patients who underwent ST for recurrent PUC demonstrated improved OS compared to those who did not receive ST and exhibited similar survival to those who never developed recurrence after primary treatment.

ABSTRACT

Physician-led perioperative surgical home models are developing as a method for improving the American health care system. These models are novel, team-based approaches that help to provide continuity of care throughout the perioperative period. Another avenue for improving care for surgical patients is the use of enhanced recovery after surgery pathways. These are well-described methods that have shown to improve perioperative outcomes. An established perioperative surgical home model can help implementation, efficiency, and adherence to enhanced recovery after surgery pathways. For these reasons, the Tennessee Valley Healthcare System, Nashville Veterans Affairs Medical Center created an Anesthesiology Perioperative Care Service that provides comprehensive care to surgical patients from their preoperative period through the continuum of their hospital course and postdischarge follow-up. In this brief report, we describe the development, implementation, and preliminary outcomes of the service.

ABSTRACT

INTRODUCTION: The study aimed to investigate oncological outcomes of patients with concomitant bladder cancer (BC) and urethral carcinoma. METHODS: This is a multicenter series of 110 patients (74 men, 36 women) diagnosed with urethral carcinoma at 10 referral centers between 1993 and 2012. Kaplan-Meier analysis was used to investigate the impact of BC on survival, and Cox regression multivariable analysis was performed to identify predictors of recurrence. RESULTS: Synchronous BC was diagnosed in 13 (12%) patients, and the median follow-up was 21 months (interquartile range 4-48). Urethral cancers were of higher grade in patients with synchronous BC compared to patients with non-synchronous BC (p = 0.020). Patients with synchronous BC exhibited significantly inferior 3-year recurrence-free survival (RFS) compared to patients with non-synchronous BC (63.2 vs. 34.4%; p = 0.026). In multivariable analysis, inferior RFS was associated with clinically advanced nodal stage (p < 0.001), proximal tumor location (p < 0.001) and synchronous BC (p = 0.020). CONCLUSION: The synchronous presence of BC in patients diagnosed with urethral carcinoma has a significant adverse impact on RFS and should be an impetus for a multimodal approach.

ABSTRACT

PURPOSE: To evaluate risk factors for survival in a large international cohort of patients with primary urethral cancer (PUC). METHODS: A series of 154 patients (109 men, 45 women) were diagnosed with PUC in ten referral centers between 1993 and 2012. Kaplan-Meier analysis with log-rank test was used to investigate various potential prognostic factors for recurrence-free (RFS) and overall survival (OS). Multivariate models were constructed to evaluate independent risk factors for recurrence and death. RESULTS: Median age at definitive treatment was 66 years (IQR 58-76). Histology was urothelial carcinoma in 72 (47 %), squamous cell carcinoma in 46 (30 %), adenocarcinoma in 17 (11 %), and mixed and other histology in 11 (7 %) and nine (6 %), respectively. A high degree of concordance between clinical and pathologic nodal staging (cN+/cN0 vs. pN+/pN0; p < 0.001) was noted. For clinical nodal staging, the corresponding sensitivity, specificity, and overall accuracy for predicting pathologic nodal stage were 92.8, 92.3, and 92.4 %, respectively. In multivariable Cox-regression analysis for patients staged cM0 at initial diagnosis, RFS was significantly associated with clinical nodal stage (p < 0.001), tumor location (p < 0.001), and age (p = 0.001), whereas clinical nodal stage was the only independent predictor for OS (p = 0.026). CONCLUSIONS: These data suggest that clinical nodal stage is a critical parameter for outcomes in PUC.

ABSTRACT

The effect of radical cystectomy and extended pelvic lymph node dissection (RC/PLND) on the survival of patients with locally advanced and/or regionally metastatic bladder cancer is unknown. However, emerging evidence suggests that there may be survival benefit to a subset of select patients with this disease who demonstrate a response to chemotherapy. This article will review the current literature on the role of RC/PLND in the consolidative treatment of locally advanced and regionally metastatic bladder cancer.

ABSTRACT

BACKGROUND AND PURPOSE: Liposomal bupivacaine is a delayed-release preparation providing up to 72 hours of local analgesia. It costs much more than standard bupivacaine, however. A prospective, randomized, patient-blinded, controlled trial was performed to assess the efficacy of liposomal bupivacaine versus 0.25% bupivacaine when injected into surgical incisions during laparoscopic and robot-assisted urologic surgery. METHODS: A total of 206 adults were randomized to receive liposomal bupivacaine or 0.25% bupivacaine. All surgical incisions were injected with liposomal bupivacaine or 0.25% bupivacaine with systematic dosing. The primary outcome was total opioid consumption during the postoperative hospital stay. All opioid doses were converted to morphine equivalents. Secondary end points included pain scores using visual analog pain scales, duration of hospital stay, and the time to first opioid use. A subgroup analysis was performed for renal surgery patients. RESULTS: There was no significant difference in median total opioid use during the hospital stay between those who received liposomal bupivacaine (15 [interquartile range (IQR) 6.7-27] mg) and 0.25% bupivacaine (17.3 [IQR 8.3-30.5] mg) (P=0.39). Furthermore, pain scores, length of hospital stay, and time to first opioid use did not differ between groups. Subgroup analysis of laparoscopic renal surgery revealed no difference between liposomal bupivacaine and 0.25% bupivacaine. CONCLUSIONS: For laparoscopic and robot-assisted urologic surgery, there is no significant difference between liposomal bupivacaine and 0.25% bupivacaine for local analgesia at the incision sites.

ABSTRACT

PURPOSE: There are growing concerns regarding the overtreatment of localized prostate cancer. It is also relatively unknown whether there has been increased uptake of observational strategies for disease management. We assessed the temporal trend in observation of clinically localized prostate cancer, particularly in men with low risk disease, who were young and healthy enough to undergo treatment. MATERIALS AND METHODS: We performed a retrospective cohort study using the SEER-Medicare database in 66,499 men with localized prostate cancer between 2004 and 2009. The main study outcome was observation within 1 year after diagnosis. We performed multivariable analysis to develop a predictive model of observation adjusting for diagnosis year, age, risk and comorbidity. RESULTS: Observation was performed in 12,007 men (18%) with a slight increase with time from 17% to 20%. However, there was marked increase in observation from 18% in 2004 to 29% in 2009 in men with low risk disease. Men 66 to 69 years old with low risk disease and no comorbidities had twice the odds of undergoing observation in 2009 vs 2004 (OR 2.12, 95% CI 1.73-2.59). Age, risk group, comorbidity and race were independent predictors of observation (each p <0.001), in addition to diagnosis year. CONCLUSIONS: We identified increasing use of observation for low risk prostate cancer between 2004 and 2009 even in men young and healthy enough for treatment. This suggests growing acceptance of surveillance in this group of patients.
