RESUMO
PURPOSE: To describe the incidence and management of patients who develop a prostatic urethral (PU) urothelial carcinoma recurrence after Bacillus Calmette-Guerin (BCG) induction for non-muscle invasive bladder cancer (NMIBC). MATERIALS AND METHODS: We performed a retrospective cohort study of all patients who received BCG induction at our institution from 1996 to 2021 (Nâ¯=â¯642) for NMIBC. All patients with pathologically confirmed PU involvement following BCG induction with no known PU involvement pre-BCG were included. We describe the presentation, management, and outcomes for PU recurrence. RESULTS: Among the 642 patients, 21 (3.3%) patients had a PU recurrence after BCG induction. 8 (38%) patients received >2 cycles of BCG induction prior to the recurrence. Median time from induction to PU recurrence was 21 months and 12 (57.1%) patients had concurrent bladder recurrence. At the time of their PU recurrence, 14/21 (67%) of patients were deemed BCG Unresponsive. Nearly all (18/21) were high grade, and 10 were stage Tis, 7 Ta, and 3 T1, and 1 T2. 19/21 (90%) patients received bladder sparing treatment: 6 with TURBT and BCG, 6 with TURBT and intravesical chemotherapy, 5 with TURBT only, and 2 did not receive immediate treatment of their PU recurrence due to advanced stage of disease. 2/21 (9.5%) received a radical cystectomy for initial treatment of the post-BCG PU recurrence, of which all were >pT2. Median follow-up time from BCG induction to the patient's last visit was 64.5 months. Following treatment of PU recurrence, 15/18 patients had another recurrence at a median of 5 months: about 47% of recurrences were bladder only and 14% recurred only in the PU as well. About 1 patient received a RC after the second recurrence and was pT2. CONCLUSION: Patients with PU recurrences following intravesical BCG have a high-risk disease phenotype with a significant risk of recurrence. Conservative management may be appropriate for well-selected patients who do not desire a cystoprostatectomy.

BACKGROUND: The intravesical instillation of the paclitaxel-hyaluronan conjugate ONCOFID-P-B™ in patients with bacillus Calmette-Guérin (BCG)-unresponsive bladder carcinoma in situ (CIS; NCT04798703 phase I study), induced 75 and 40% of complete response (CR) after 12 weeks of intensive phase and 12 months of maintenance phase, respectively. The aim of this study was to provide a detailed description of the tumor microenvironment (TME) of ONCOFID-P-B™-treated BCG-unresponsive bladder CIS patients enrolled in the NCT04798703 phase I study, in order to identify predictive biomarkers of response. METHODS: The composition and spatial interactions of tumor-infiltrating immune cells and the expression of the most relevant hyaluronic acid (HA) receptors on cancer cells, were analyzed in biopsies from the 20 patients enrolled in the NCT04798703 phase I study collected before starting ONCOFID-P-B™ therapy (baseline), and after the intensive and the maintenance phases. Clinical data were correlated with cell densities, cell distribution and cell interactions. Associations between immune populations or HA receptors expression and outcome were analyzed using univariate Cox regression and log-rank analysis. RESULTS: In baseline biopsies, patients achieving CR after the intensive phase had a lower density of intra-tumoral CD8+ cytotoxic T lymphocytes (CTL), but also fewer interactions between CTL and macrophages or T-regulatory cells, as compared to non-responders (NR). NR expressed higher levels of the HA receptors CD44v6, ICAM-1 and RHAMM. The intra-tumoral macrophage density was positively correlated with the expression of the pro-metastatic and aggressive variant CD44v6, and the combined score of intra-tumoral macrophage density and CD44v6 expression had an AUC of 0.85 (95% CI 0.68-1.00) for patient response prediction. CONCLUSIONS: The clinical response to ONCOFID-P-B™ in bladder CIS likely relies on several components of the TME, and the combined evaluation of intra-tumoral macrophages density and CD44v6 expression is a potentially new predictive biomarker for patient response. Overall, our data allow to advance a potential rationale for combinatorial treatments targeting the immune infiltrate such as immune checkpoint inhibitors, to make bladder CIS more responsive to ONCOFID-P-B™ treatment.

Importance: In January 2023, the US Centers for Disease Control and Prevention and the US Food and Drug Administration noted a safety concern for ischemic stroke among adults aged 65 years or older who received the Pfizer-BioNTech BNT162b2; WT/OMI BA.4/BA.5 COVID-19 bivalent vaccine. Objective: To evaluate stroke risk after administration of (1) either brand of the COVID-19 bivalent vaccine, (2) either brand of the COVID-19 bivalent plus a high-dose or adjuvanted influenza vaccine on the same day (concomitant administration), and (3) a high-dose or adjuvanted influenza vaccine. Design, Setting, and Participants: Self-controlled case series including 11â¯001 Medicare beneficiaries aged 65 years or older who experienced stroke after receiving either brand of the COVID-19 bivalent vaccine (among 5â¯397â¯278 vaccinated individuals). The study period was August 31, 2022, through February 4, 2023. Exposures: Receipt of (1) either brand of the COVID-19 bivalent vaccine (primary) or (2) a high-dose or adjuvanted influenza vaccine (secondary). Main Outcomes and Measures: Stroke risk (nonhemorrhagic stroke, transient ischemic attack, combined outcome of nonhemorrhagic stroke or transient ischemic attack, or hemorrhagic stroke) during the 1- to 21-day or 22- to 42-day risk window after vaccination vs the 43- to 90-day control window. Results: There were 5â¯397â¯278 Medicare beneficiaries who received either brand of the COVID-19 bivalent vaccine (median age, 74 years [IQR, 70-80 years]; 56% were women). Among the 11â¯001 beneficiaries who experienced stroke after receiving either brand of the COVID-19 bivalent vaccine, there were no statistically significant associations between either brand of the COVID-19 bivalent vaccine and the outcomes of nonhemorrhagic stroke, transient ischemic attack, nonhemorrhagic stroke or transient ischemic attack, or hemorrhagic stroke during the 1- to 21-day or 22- to 42-day risk window vs the 43- to 90-day control window (incidence rate ratio [IRR] range, 0.72-1.12). Among the 4596 beneficiaries who experienced stroke after concomitant administration of either brand of the COVID-19 bivalent vaccine plus a high-dose or adjuvanted influenza vaccine, there was a statistically significant association between vaccination and nonhemorrhagic stroke during the 22- to 42-day risk window for the Pfizer-BioNTech BNT162b2; WT/OMI BA.4/BA.5 COVID-19 bivalent vaccine (IRR, 1.20 [95% CI, 1.01-1.42]; risk difference/100â¯000 doses, 3.13 [95% CI, 0.05-6.22]) and a statistically significant association between vaccination and transient ischemic attack during the 1- to 21-day risk window for the Moderna mRNA-1273.222 COVID-19 bivalent vaccine (IRR, 1.35 [95% CI, 1.06-1.74]; risk difference/100â¯000 doses, 3.33 [95% CI, 0.46-6.20]). Among the 21â¯345 beneficiaries who experienced stroke after administration of a high-dose or adjuvanted influenza vaccine, there was a statistically significant association between vaccination and nonhemorrhagic stroke during the 22- to 42-day risk window (IRR, 1.09 [95% CI, 1.02-1.17]; risk difference/100â¯000 doses, 1.65 [95% CI, 0.43-2.87]). Conclusions and Relevance: Among Medicare beneficiaries aged 65 years or older who experienced stroke after receiving either brand of the COVID-19 bivalent vaccine, there was no evidence of a significantly elevated risk for stroke during the days immediately after vaccination.

OBJECTIVE: To compare the cost-utility of initial management of high-grade T1 non-muscle invasive bladder cancer (HGT1 NMIBC) with intravesical BCG vs immediate radical cystectomy. High-risk NMIBC patients may climb a costly ladder of treatments, culminating in radical cystectomy for oncologic or symptomatic benefit in up to one-third. This high healthcare resource utilization presents a challenging dilemma in balancing sufficiently aggressive management with cost, toxicity, and quality-of-life. METHODS: Cost-utility of initially managing HGT1 with intravesical BCG and early radical cystectomy with ileal conduit urinary diversion was compared using decision-analytic Markov models. Five-year oncologic outcomes, adverse event rates, and published utility values were extracted from literature. Costs were calculated from a US Medicare perspective in 2021 US dollars. Sensitivity analysis identified drivers of cost and break-even points for recurrence and progression. RESULTS: Mean costs were $26,093 for intravesical BCG and $39,720 for immediate radical cystectomy, though cystectomy generated a gain of 2.2 quality-adjusted life years (QALYs) compared to intravesical BCG. Immediate cystectomy was a more cost-effective management strategy for HGT1 NMIBC with an incremental CE ratios (ICER) of $7120/QALY. The costs associated with cystectomy, TURBT, and BCG toxicity had the greatest impact on ICER. One-way sensitivity analysis demonstrated that intravesical BCG became a cost-effective management strategy if the 5-year recurrence rate of HG T1 was less than 56% or the 5-year progression rate to MIBC was less than 4%. CONCLUSION: At current prices, treatment of high-grade T1 NMIBC with early radical cystectomy is more cost-effective management strategy than initial treatment with intravesical BCG.

INTRODUCTION: Bacillus Calmette-Guerin (BCG) is the most effective therapy available to treat high-risk nonmuscle invasive bladder cancer (NMIBC) patients. However, for patients with immunomodulating conditions BCG is a relative contraindication due to efficacy and safety concerns. To our knowledge, no population-level study evaluating the efficacy and safety profile of BCG for immunomodulated patients exists. METHODS: NMIBC patients aged 66 years or older were identified in the Surveillance, Epidemiology, and End Results (SEER) - Medicare database from 1975-2013. All patients completed adequate BCG (at least 5 plus 2 treatments completed within 12 months of diagnosis). Two groups were defined: an immunomodulated population identified by immunomodulating conditions such as solid-organ transplantation, HIV, and autoimmune conditions, and an immunocompetent group. The primary endpoint was 5-year progression-free survival defined as progression to systemic chemotherapy, checkpoint inhibitors, radical or partial cystectomy, metastasis, or cancer-specific death. A safety analysis was performed as a secondary outcome. RESULTS: In a total of 4,277 patients with NMIBC who completed adequate BCG, 606 (14.2%) were immunomodulated. The immunomodulated group was older at diagnosis (P < 0.001), more likely to be female (P < 0.001), more likely to live in a metropolitan area (P < 0.001), and had higher Charlson comorbidity scores (P < 0.001). There were no differences in progression to chemotherapy (Pâ¯=â¯0.17), checkpoint inhibitors (P > 0.99), radical cystectomy (Pâ¯=â¯0.40), partial cystectomy (Pâ¯=â¯0.93), metastasis (Pâ¯=â¯0.19), cancer-specific death (Pâ¯=â¯0.18) or 5-year total bladder cancer progression (Pâ¯=â¯0.30) between the groups. For the safety analysis, rates of disseminated BCG were similar between immunomodulated and immunocompetent patients (0.7% vs. <1.8%, Pâ¯=â¯0.51). On multivariable analysis 5-year total bladder cancer progression (HR 1.07 [CI 0.88-1.30]) was similar between the groups. CONCLUSION: Rates of bladder cancer progression and disseminated BCG complications 5-years after BCG therapy were similar regardless of immunomodulation status. These findings suggest that BCG intravesical therapy can be offered to immunomodulated patients with high-risk NMIBC although theoretical infectious complication risks remain.

Introduction: Perioperative (neoadjuvant and adjuvant) pembrolizumab has shown favorable efficacy in patients with early-stage non-small cell lung cancer (NSCLC). This study aims to evaluate the cost-effectiveness of this treatment from the perspective of the United States healthcare payers. Methods: We established a Markov model to compare the cost-effectiveness of perioperative pembrolizumab with that of neoadjuvant chemotherapy in 21-day cycles, utilizing data from the phase 3 KEYNOTE-671 trial. Additional data were extracted from other publications or online sources. Sensitivity analyses were conducted to evaluate the robustness of the findings. A willingness-to-pay threshold of $150,000 per quality-adjusted life-years (QALYs) gained was established. The main outcomes of this study were the measurement of QALYs, overall costs, incremental cost-effectiveness ratio (ICER), and net monetary benefit (NMB). Results: During a 10-year time horizon, the total costs of perioperative pembrolizumab and the control treatment were $224,779.1 and $110,026.3, respectively. The QALYs were 4.19 and 2.97 for the two treatments, respectively, which led to an ICER of $94,222.29 per QALY gained. The NMB at the WTP threshold at $150,000 per QALY gained was $67,931.3. One-way sensitivity analysis identified the cost of pembrolizumab as the primary factor influencing cost-effectiveness. Probabilistic sensitivity analysis indicated a 97.7% probability of perioperative pembrolizumab being cost-effective at the WTP threshold. Conclusions: From the perspective of the United States healthcare payers, perioperative pembrolizumab is a cost-effective treatment for patients with early-stage NSCLC.

PURPOSE: To assess associations between adherence to and persistence with adjuvant hormone therapy and mortality among older women with breast cancer. METHODS: The surveillance, epidemiology, and end results data linked with U.S. Medicare claims was used. This study included older women diagnosed with stage I-III hormone receptor-positive breast cancer from 2009 through 2017. Adherence was defined as having proportion of days covered (PDC) ≥ 0.80. Persistence was defined as having no discontinuation, i.e., no break of ≥ 180 continuous days. Length of persistence was calculated as time from therapy initiation to discontinuation. Cox models with time-dependent covariates were used to assess associations between adherence and persistence with mortality. RESULTS: This study included 25,796 women. Adherence rates were 78.1 percent, 75.2 percent, 72.4 percent, 70.0 percent, and 61.5 percent from year 1 to year 5 after hormone therapy initiation. Persistence rates were 87.5 percent, 81.7 percent, 77.1 percent, 72.9 percent, and 68.9 percent through cumulative intervals of 1 year up to 5 years. Adherence was associated with all-cause mortality but not associated with breast cancer-specific mortality. Persistent women had lower risk of all-cause mortality and breast cancer-specific mortality. Each additional year of persistence had additional contributions to survival benefits (11% decreased risk of all-cause mortality and 37% decreased risk of breast cancer-specific mortality). CONCLUSION: This study confirms the detrimental effect of nonadherence to adjuvant hormone therapy across up to 5 years on all-cause survival in older U.S. women. It also reveals the survival benefits associated with having longer persistence across up to 5 years.

OBJECTIVE: Among patients diagnosed with non-muscle invasive bladder cancer (NMIBC), those with high risk disease have the greatest risk of recurrence and disease progression. The underutilization of intravesical immunotherapy with Bacillus Calmette-Guérin (BCG) has been a longstanding concern in clinical practice. This study aimed to determine the disparities present in receipt of adjuvant intravesical chemotherapy and immunotherapy in treatment of patients with high grade NMIBC following initial transurethral resection of a bladder tumor (TURBT). METHODS: The California Cancer Registry data was used to identify 19,237 patients diagnosed with high grade NMIBC who underwent TURBT. Treatment variables include re-TURBT, re-TURBT and intravesical chemotherapy (IVC) and/or BCG. Independent variables include age, sex, race/ethnicity, neighborhood socioeconomic status (nSES), primary insurance payer and marital status at diagnosis. Multiple logistic regression and multinomial regression models were used to examine variation in the treatments received following TURBT. RESULTS: The proportion of patients receiving TURBT followed by BCG was similar across all racial and ethnic groups (28%-32%). BCG therapy was higher in patients belonging to the highest nSES quintile (37% for highest vs. 23%-26% for the 2 lowest quintiles). In multiple variable analyses, receipt of any intravesical therapy (IVT) was influenced by nSES, age, marital status, race/ethnicity, and insurance type. Patients in the lowest nSES quintile had a 45% less likelihood of receiving IVT compared to the highest nSES group (OR [95%CI]: 0.55[0.49, 0.61]). Race/ethnicity differences in receipt of any adjuvant therapy were noted in the middle to lowest nSES quintile for Hispanic and Asian/Pacific Islander patients when compared to non-Hispanic White patients. When comparing variation in treatment by insurance type at diagnosis, those with Medicare or other insurance were 24% and 30% less likely to receive BCG after TURBT compared to those with private insurance, (OR [95%CI]: 0.76 [0.70, 0.82] and 0.70[0.62, 0.79]) respectively. CONCLUSION: In patients with a diagnosis of high risk NMIBC, disparities in utilization of BCG are seen based on SES, age, and insurance type.

INTRODUCTION: Treatment naïve patients with high-risk non-muscle invasive bladder cancer (NMIBC) are treated with bacillus Calmette-Guérin (BCG) therapy as the standard of care. Recently, intravesical sequential gemcitabine-docetaxel in the BCG-naïve setting was shown to be well-tolerated and effective, raising the possibility of a new first line intravesical therapy. Cost effectiveness of this intervention remains unknown; therefore, we designed a cost effectiveness study evaluating BCG vs. sequential gemcitabine-docetaxel in patients with high risk NMIBC. METHODS: Using TreeAgePro 2019 software, we developed a Markov model to evaluate BCG vs. gemcitabine-docetaxel from the U.S. Medicare perspective with a 2-year time horizon. Model probabilities and utilities were derived from published literature. Direct costs were obtained from Medicare cost databases. Our primary outcomes were effectiveness (measured in quality adjusted life years [QALYs]), cost and the incremental cost-effectiveness ratio with a willingness to pay threshold of $100,000. RESULTS: Our results indicate that while both treatments resulted in similar QALYs of 1.76, the mean costs per patient at 2 years were $12,363 and $7,090 for BCG and gemcitabine-docetaxel, respectively. Therefore, the BCG strategy was dominated by the gemcitabine-docetaxel strategy as it was equally effective and less costly. One way sensitivity analyses were completed and gemcitabine-docetaxel remained a cost-effective strategy. CONCLUSIONS: The findings of this preliminary cost-effectiveness analysis are novel in that they highlight a well tolerated, efficacious drug that is less expensive than the traditional gold standard therapy. In modern medicine, we are more often challenged by agents with marginally increased efficacy but at significantly higher costs; gemcitabine-docetaxel represents a rare entity which is a success for both patients and healthcare systems alike.

INTRODUCTION: The KEYNOTE-054 trial found that adjuvant treatment with pembrolizumab improved recurrence-free survival versus placebo in completely resected high-risk stage III melanoma patients. We assessed the cost-effectiveness of adjuvant pembrolizumab in Colombia compared with watchful waiting, a widely used strategy despite the high risk of recurrence with surgery alone. METHODS: A four-health state [recurrence-free (RF), locoregional recurrence (LR), distant metastases (DM), and death) Markov model was developed to assess the lifetime medical costs and outcomes (3% annual discount), along with cost-effectiveness ratios (ICERs). The transitions from the RF and LR states were modeled using KEYNOTE-054 data, and those from the DM state were modeled using data from the KEYNOTE-006 trial and a network meta-analysis of advanced treatments received after adjuvant pembrolizumab and watchful waiting. The health state utilities were derived from KEYNOTE-054 Euro-QoL data and literature. Costs are expressed in 2021 Colombian pesos (COP). RESULTS: Over a 46-year time horizon, patients on adjuvant pembrolizumab and watchful waiting were estimated to gain 9.69 and 7.56 quality-adjusted life-years (QALYs), 10.83 and 8.65 life-years (LYs), and incur costs of COP 663,595,726 and COP 563,237,206, respectively. The proportion of LYs spent in RF state was 84.63% for pembrolizumab and 72.13% for watchful waiting, yielding lower subsequent treatment, disease management, and terminal care costs for pembrolizumab. Adjuvant pembrolizumab improved survival by 2.18 LYs and 2.13 QALYs versus watchful waiting. The ICER per QALY was COP 47,081,917, primarily driven by recurrence rates and advanced melanoma treatments. The deterministic sensitivity analysis results were robust and consistent across various reasonable inputs and alternative scenarios. At a willingness-to-pay threshold of COP 69,150,201 per QALY, the probability of pembrolizumab being cost-effective was 65.70%. CONCLUSION: Pembrolizumab is cost-effective as an adjuvant treatment compared to watchful waiting among patients with high-risk stage III melanoma after complete resection in Colombia.

AIMS: Approximately 75% of bladder cancer (BC) cases present as non-muscle-invasive BC (NMIBC). In patients with high-risk NMIBC, the mainstay treatment is intravesical Bacillus Calmette-Guérin (BCG), with immediate radical cystectomy (RC) as an alternative treatment option. The aim of the present study was to evaluate the cost-utility of BCG versus RC in patients with high-risk NMIBC from the UK healthcare payer perspective. MATERIALS AND METHODS: A six-state Markov model was developed that covered controlled disease, recurrence, progression to muscle-invasive BC, metastatic disease, and death. The model included adverse events of BCG and RC and monitoring and palliative care. Drug costs were obtained from the British National Formulary. Intravesical delivery, RC, and monitoring costs were sourced from the National Tariff Payment System and the literature. Utility data were obtained from the literature. Analyses were run over a 30-year time horizon, with future costs and effects discounted at 3.5% per annum. One-way and probabilistic sensitivity analyses were performed. RESULTS: The base case analysis comparing BCG with RC showed that BCG would increase life expectancy by 0.88 years versus RC, from 7.74 to 8.62 years. BCG resulted in an increase of 0.76 quality-adjusted life years (QALYs) versus RC, from 5.63 to 6.39 QALYs. Patients incurred lower lifetime costs if treated with BCG (£47,753) than with RC (£64,264). Cost savings were mainly driven by the lower cost of BCG versus RC, and palliative care costs. Sensitivity analyses showed that results were robust to assumptions. LIMITATIONS: The evidence base informing efficacy estimates of BCG is heterogeneous as different BCG administration schedules were reported in the literature, while incidence and cost data on some BCG-associated adverse events were sparse. CONCLUSIONS: Intravesical BCG led to increased QALYs and reduced costs versus RC for patients with high-risk NMIBC from the UK healthcare payer perspective.
Intravesical Bacillus Calmette-Guérin (BCG) is a recommended immunotherapy option for patients with high-risk non-muscle invasive bladder cancer (NMIBC) who have undergone transurethral resection of bladder tumor (TURBT). BCG is known for its high efficacy and good safety profile. However, current evidence on its effectiveness against other comparators such as radical cystectomy (RC) is limited, mainly because different BCG schedules are used, particularly with regard to maintenance therapy. Given this lack of evidence, we conducted the first cost-utility analysis which considers adequate BCG therapy relative to RC for the UK. We developed a Markov model that captured the effects of the intravesical BCG and RC on NMIBC, in addition to incidences of adverse events associated with either treatment. Costs of the two treatments, their administration, maintenance, and of treatments for adverse events were modelled alongside the quality-of-life effects of NMIBC, adverse events, and palliative care. We used published clinical data and UK cost data to inform our model. Our results show that BCG was associated with higher quality-adjusted life expectancy than RC and lower total costs from the healthcare system perspective. These results imply that adequate BCG immunotherapy is likely valuable for the National Healthcare System in terms of its effects on patients and indeed cost-saving relative to RC.

OBJECTIVE: To measure the changes in treatment patterns for non-muscle invasive bladder cancer before and during the Bacillus Calmette-Guerin (BCG) drug shortage. MATERIALS AND METHODS: We used a 5% random sample of Medicare beneficiaries and identified 7971 bladder cancer patients (2648 pre-BCG shortage and 5323 during the shortage) ≥66â¯years of age who received intravesical treatment within 1â¯year of diagnosis between 2010 and 2017. The BCG shortage period was defined from July 2012 ongoing. Full induction treatment with BCG, mitomycin C, gemcitabine, or other intravesical agents was defined as receiving ≥5 of 6 treatments within 60â¯days. State-level BCG use before and during the drug shortage was compared in US states reporting at least 50 patients in each period. Independent variables included year of index date, age, sex, race, rurality, and region of residence. RESULTS: BCG utilization rates decreased 5.9% in the shortage period (95% CI (-8.2%)-(-3.7%)). The proportion of patients that completed a full induction course of BCG decreased from 31.0% in the pre-shortage period to 27.6% in the shortage period (Pâ¯=â¯.002). 84% of reporting states (16 of 19) had decreased BCG utilization ranging between 5% and 36% compared to pre-shortage rates. CONCLUSION: During the BCG drug shortage, eligible bladder cancer patients were less likely to receive gold standard intravesical BCG with a large variation in treatment patterns between US states.

INTRODUCTION: Early initiation of chemotherapy after surgery for colon cancer has survival benefits. Immediate adjuvant chemotherapy (IAC) involves giving chemotherapy during surgical resection and immediately postoperatively. This novel approach has been shown to be safe, eliminating delays in adjuvant treatment that could increase the risk of micro-metastatic spread. The aim of this study was to assess the willingness of the general public to accept IAC. MATERIALS AND METHODS: Between March and April 2021, 800 telephone interviews were conducted with a sample of adult New York State residents. The Survey Research Institute of Cornell University conducted all surveys. Kruskal-Wallis, chi-squared, and Fisher's tests were conducted using R 4.0.2. RESULTS: Three scenarios were presented: (1) receiving IAC resulting in improved survival and quality of life, (2) finishing chemotherapy earlier without survival impact, and (3) finishing chemotherapy earlier but with possible side effects. Respondents with higher education were more likely to accept (1) & (2), males were more likely to accept (2) & (3), higher income respondents were more likely to accept (1) & (3), and those with more work hours were more likely to accept (2). Lastly, 16% responded they would be very or extremely likely, and 52% respondents would be somewhat likely or likely to accept intraoperative chemotherapy, even if it may not be necessary. CONCLUSIONS: Respondents were likely to accept IAC if offered. Given the known risk of delayed adjuvant chemotherapy (AC) in colon cancer, further research is warranted to determine the survival and quality of life (QOL) benefits of IAC.

PURPOSE: Over 50% of breast cancer patients prescribed a 5-year course of daily oral adjuvant endocrine therapy (ET) are nonadherent. We investigated the role of costs and cancer medication delivery mode and other medication delivery factors on adherence. METHODS: We conducted a retrospective cohort study of commercially insured and Medicare advantage patients with newly diagnosed breast cancer in 2007-2015 who initiated ET. We examined the association between 12-month ET adherence (proportion of days covered by fills ≥ 0.80) and ET copayments, 90-day prescription refill use, mail order pharmacy use, number of pharmacies, and synchronization of medications. We used regression models to estimate nonadherence risk ratios adjusted for demographics (age, income, race, urbanicity), comorbidities, total medications, primary cancer treatments, and generic AI availability. Sensitivity analyses were conducted using alternative specifications for independent variables. RESULTS: Mail order users had higher adherence in both commercial and Medicare-insured cohorts. Commercially insured patients who used mail order were more likely to be adherent if they had low copayments (< $5) and 90-day prescription refills. For commercially insured patients who used local pharmacies, use of one pharmacy and better synchronized refills were also associated with adherence. Among Medicare patients who used mail order pharmacies, only low copayments were associated with adherence, while among Medicare patients using local pharmacies both low copayments and 90-day prescriptions were associated with ET adherence. CONCLUSION: Out-of-pocket costs, medication delivery mode, and other pharmacy-related medication delivery factors are associated with adherence to breast cancer ET. Future work should investigate whether interventions aimed at streamlining medication delivery could improve adherence for breast cancer patients.

OBJECTIVE: To evaluate the associations of socioeconomic characteristics with the management of non-muscle invasive bladder cancer (NMIBC). METHODS: We identified adult patients aged 18 to 89 years with Ta, T1, or Tis NMIBC in the NCDB. We then examined the associations of patient and socioeconomic characteristics with the guidelines-based management of high-risk NMIBC using multivariable logistic regression. RESULTS: 163,949 patients were included in the study cohort, including 64% with Ta, 32% with T1, and 4% with Tis disease. Among those diagnosed with bladder cancer, male (OR 1.24, 95%CI 1.21-1.27), uninsured (OR 1.10, 95%CI 1.01-1.19 vs. private), and non-White (OR 1.34, 95%CI 1.28-1.41 for Black; OR 1.10; 95%CI 1.03-1.18 for Other vs. White) patients were more likely to be diagnosed with high-risk disease, as well as patients from lower education level areas. Among those with high-risk NMIBC, patients who were older, non-White, Hispanic, uninsured or insured with Medicaid were less likely to receive guideline recommended intravesical BCG, while those residing in rural and higher education level areas were more likely to receive BCG. When examining non-guidelines based use of radiotherapy for HGT1 disease, older age (OR 1.06; 95% CI 1.04-1.07) and VA/Military insurance (OR 2.73; 95%CI 1.07, 6.98 vs. private) were associated with radiotherapy use. CONCLUSION: There are strong disparities in the prevalence and management of high-risk NMIBC. These observations highlight important targets for future strategies to reduce such healthcare disparities and provide more equitable bladder cancer treatment to patients.

BACKGROUND: Many patients with recurrent high-risk non-muscle invasive bladder cancer after intravesical bacillus calmette-guerin (BCG) face a difficult decision between radical cystectomy (RC) or salvage intravesical therapy (IVT). We sought to determine if there is a difference in overall survival RC and IVT after previous treatment with BCG. METHODS: We performed a retrospective cohort study of patients with Ta, T1, and Tis bladder cancer treated with induction BCG in the SEER-Medicare dataset from 2000 to 2015. We used a proportional hazards regression model to compare differences in survival between patients having RC and IVT. We adjusted for confounding using a propensity score and stratified our analysis according to timing of treatment and stage at diagnosis. RESULTS: We identified 3940 patients who received either IVT (79%) or RC (21%) following induction BCG. Among patients treated within 12 months of BCG, there was no significant difference in survival between RC and IVT (HR 0.92, 95% CI 0.81-1.04) and 17% of patients having early IVT ultimately required RC. Among patients treated at least 12 months after BCG, RC was associated with worse survival than IVT (HR 1.19, 95% CI 1.06-1.35) and 10% of patients having late IVT ultimately required RC. CONCLUSION: Among patients with bladder cancer who required additional treatments after induction BCG, we did not observe a difference in overall survival between IVT and RC within 12 months of starting BCG. While RC remains the gold-standard for high risk recurrent NMIBC after BCG, bladder preservation with IVT may be appropriate for well-selected patients.

Importance: Adjuvant therapies are often approved based on improvements in disease-, progression-, or relapse-free survival (ie, an event). An important estimate in adjuvant therapies is the cost per event averted. Objective: To characterize the costs per event averted of anticancer drugs approved by the US Food and Drug Administration (FDA) between January 2018 and March 2022. Design, Setting, and Participants: In this cross-sectional study, all approvals were reviewed from the FDA website. Approvals selected for the analysis needed to be drawn from randomized trials involving anticancer drugs studied in the adjuvant treatment of solid tumors. Treatments of nonsolid tumors; nonrandomized, noncontrolled trials; and unpublished trials were excluded. Approvals between January 2018 and March 2022 were included, and 11 trials met inclusion criteria. The monthly costs of each agent were abstracted from the Micromedex RED BOOK database. All variables included in calculations were derived from the original trial publication. Information abstracted for each approval included the name of the drug approved, name of the trial, primary end point, dosing regimen in the trial, median duration of treatment, tumor type, monthly costs per drug, and the number needed to treat for the primary end point. Data were analyzed in March 2022. Main Outcomes and Measures: The cost per event averted for each agent studied in each clinical trial; the monthly cost of each drug, the cost per patient for each drug, the primary clinical end point studied in each trial; the study's design and setting. Results: A total of 11 approvals were included in the study. From January 2018 to March 2022, all approvals were based on a surrogate end point as the primary end point, with no trials demonstrating, to date, an overall survival benefit. The median cost per event averted of drugs in the adjuvant setting was $1â¯610â¯000 (range, $820â¯000 to $2â¯640â¯000). The median cost of a complete adjuvant treatment was $158â¯000 per patient. Conclusions and Relevance: In this cross-sectional study, anticancer agents in the adjuvant setting were approved based on disease-, progression-, event-, or relapse-free survival. Costs per event averted were high. These findings suggest that these drugs may not achieve wide or global use unless their efficacy improves or their prices decrease.

A DOENÇA: O câncer de próstata (CP) é uma doença heterogênea com diversos subtipos, que acomete a glândula próstata. A função dessa glândula é a produção do líquido prostático e do líquido seminal, que juntos são capazes de nutrir os espermatozoides e auxiliá-los na sua mobilidade. No adulto jovem a próstata possui o tamanho aproximado de uma ameixa, e pode de modo fisiológico aumentar de tamanho, de acordo com o envelhecimento. Na maioria dos casos o CP apresenta evolução silenciosa, podendo não apresentar sinais e sintomas em sua fase inicial. Entretanto, as manifestações clínicas mais comuns são: dificuldade de urinar, demora em iniciar ou finalizar o jato urinário, diminuição do jato urinário, necessidade de urinar mais vezes durante o dia ou a noite e presença de sangue na urina. Como esses sinais e sintomas são inespecíficos é necessário a avaliação médica para fins de diagnóstico diferencial. TRATAMENTOS SISTÊMICOS DE PRIMEIRA LINHA DISPONÍVEIS: As Diretrizes Diagnósticas e Terapêuticas (DDT) do adenocarcinoma de próstata, publicadas em 2016, estão em processo de atualização no momento. Para pacientes assintomáticos ou pouco sintomáticos é recomendado como tratamento de primeira linha a utilização de novos agentes inibidores do eixo de sinalização androgênica, preferencialmente, abiraterona ou enzalutamida (nível de evidência 1 e força de recomendação A). Para pacientes sintomáticos é recomendado como tratamento de primeira linha a quimioterapia com docetaxel e o radiofármaco Radium-223 (nível de evidência 1 e força de recomendação A). ESTRATÉGIA DE BUSCA: Os medicamentos em fase de desenvolvimento para o tratamento de primeira linha de pacientes com câncer de próstata metastático
