Economic outcomes in patients with chemotherapy-naive metastatic castration-resistant prostate cancer treated with enzalutamide or abiraterone acetate plus prednisone
Introduction: Prostate cancer (PC) is the second leading cause of cancer death among US men and accounts for considerable healthcare expenditures. We evaluated economic outcomes in men with chemotherapy-naı¨ve metastatic castration-resistant PC (mCRPC) treated with enzalutamide or abiraterone acetate plus prednisone (abiraterone). Methods: We performed a retrospective analysis on 3174 men (18 years or older) utilizing the Veterans Health Administration (VHA) database from 1 April 2014 to 31 March 2018. Men with mCRPC were included if they had at least one pharmacy claim for enzalutamide or abiraterone (first claim date = index date) following surgical or medical castration, had no chemotherapy treatment within 12 months prior to the index date, and had continuous VHA enrollment for at least 12 months pre- and post-index date. Men were followed until death, disenrollment, or end of study and were 1:1 propensity score matched (PSM). All-cause and PC-related resource use and costs per patient per month (PPPM) in the 12 months post index were compared between matched cohorts. Results: We identified 1229 men with mCRPC prescribed enzalutamide and 1945 prescribed abiraterone with mean ages of 74 and 73 years, respectively. After PSM, each cohort had 1160 patients. The enzalutamide cohort had fewer all-cause (2.51 vs 2.86; p\0.0001) and PC-related outpatient visits (0.86 vs 1.03; p\0.0001), with corresponding lower all-cause (3115; p\0.0001) and PC-related (1775; p\0.0001) PPPM outpatient costs compared with the abiraterone cohort. Allcause total costs (medical and pharmacy) PPPM (9092; p = 0.0002) and PC-related total costs PPPM (7280; p\0.0001) were significantly lower in the enzalutamide cohort compared with the abiraterone cohort. Conclusions: Enzalutamide-treated men with chemotherapy-naı ¨ve mCRPC had significantly lower resource utilization and healthcare costs compared with abiraterone-treated men.

Quality of life in QUILT 3.032 study: Patients with BCG-unresponsive non-muscle invasive bladder cancer (NMIBC) receiving IL-15RαFc superagonist N-803 plus BCG
495 Background: Patients (pts) with BCG-unresponsive NMIBC have limited treatment options and are at an increased risk for cystectomy. Nogapendekin alfa inbakicept (NAI, also known as N-803), is an interleukin-15 superagonist (IL-15RαFc), which synergizes with BCG to elicit innate immune memory resulting in durable complete responses (CRs) in this patient population. In an open-label, 3-cohort, multicenter Phase 2/3 study of intravesical BCG plus NAI in BCG-unresponsive high-grade NMIBC (QUILT 3.032; NCT03022825), pts with carcinoma in situ (CIS; Cohort A) have a CR rate of 71% (median duration 26.6 months), 89.2% cystectomy avoidance and 100% bladder cancer specific survival at 24 months. We submit here the first quality of life (QOL) data report in the same pts cohort. Methods: Cohort A: 86 pts (median age 73 years; 87% male) with histologically confirmed BCG-unresponsive CIS with or without Ta/T1 disease, treated with intravesical BCG 50 mg plus NAI 400 μg. Mean baseline ECOG score was 0.183, with 82% of pts having score = 0. QOL was measured by the EORTC QOL Questionnaire Core 30 (QLQ-C30) and QOL NIMBC-Specific 24 Questionnaire (QLQ-NMIBC24). Results: Multivariate analyses have shown no significant changes over time for any of the measured QOL domains. Mild worsening vs. baseline in feeling ill was reported by 6% and 3% of pts by week 27 and 52, while 4% and 6% reported improvement. By week 78 and 104, 7% and 9% of pts reported improvement vs. baseline in their wellbeing with the majority being stable (non-significant). No statistically significant variations were detected in the physical function (PF) score (baseline vs. week 27, 52, 78 and 104). Higher PF scores were observed in pts responding to the therapy vs. non-responders; however, baseline value of PF was also higher in responders vs. non-responders. In contrast to historical results of BCG alone, week 27 physical function scores were numerically higher than baseline, with a subsequent nadir at week 78 and recovery to baseline by week 104 (non-significant). Hospitalizations for any reason remained low (0% - 6% per assessments) during the study. Conclusions: QOL measurement supports good tolerability of the intravesical NAI plus BCG in BCG-unresponsive, high-grade NMIBC pts with CIS. These results further strengthen the evidence of a favorable benefit: risk ratio of this novel combination immunotherapy, in a challenging disease. Clinical trial information: NCT03022825
Current status of endemic goiter in Croatia: The results of a nationwide study (1995)
In the beginning of the nineties, 40 years after introduction of iodine prophylaxis in Croatia, on a basis of a frequent reports coming from general practitioners about the presence of a rather high prevalence of goiter among schoolchildren, a nationwide study was initiated with the aim to determine the real prevalence of goiter in the country. A total of 2856 schoolchildren of both sexes, aged 7-15 years, were included into the study. Investigations were designed in a way to cover most of geographical regions in Croatia and subjects were randomly selected. The prevalence of goiter in schoolchildren was assessed by palpation and in part by ultrasonography of the neck. At the same time urinary iodine excretion was measured and iodine content in salt samples was determined. The results have revealed the persistence of mild endemic goiter in inland parts of Croatia with the prevalence of 6-29% in the age group 7-11 years and those of 10-43% among the age group 12-15 years. The overall goiter prevalence in schoolchildren in Croatia fluctuates from 8% to 35%. Such prevalence, most probably due to less than optimum iodine intake, is unlikely to change until iodine content of the salt is increased from its present level of 10 mg of Kl per kg of salt.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Does race predict the development of metastases in men who receive androgen-deprivation therapy for a biochemical recurrence after radical prostatectomy?
BackgroundIn this study among men who underwent radical prostatectomy (RP), African American men (AAM) were 28% more likely to develop recurrent disease compared with Caucasian men (CM). However, among those who had nonmetastatic, castration-resistant prostate cancer (CRPC), race did not predict metastases or overall survival. Whether race predicts metastases among men who receive androgen-deprivation therapy (ADT) after a biochemical recurrence (BCR) (ie, before CRPC but after BCR) is untested.MethodsThe authors identified 595 AAM and CM who received ADT for a BCR that developed after RP between 1988 and 2015 in the Shared Equal-Access Regional Cancer Hospital (SEARCH) database. Univariable and multivariable Cox models were used to test the association between race and the time from ADT to metastases. Secondary outcomes included the time to CRPC, all-cause mortality, and prostate cancer-specific mortality.ResultsDuring a median follow-up of 66 months after ADT, 62 of 354 CM (18%) and 38 of 241 AAM (16%) developed metastases. AAM were younger at the time they received ADT (63 vs 67 years; P < .001), had received ADT in a more recent year (2008 vs 2006; P < .001), had higher prostate-specific antigen levels at RP (11.1 vs 9.2 ng/mL; P < .001), lower pathologic Gleason scores (P = .004), and less extracapsular extension (38% vs 48%; P = .022). On multivariable analysis, there was no association between race and metastases (hazard radio, 1.20; P = .45) or any of the other secondary outcomes (all P > .5).ConclusionsAmong veterans who received ADT post-BCR after RP, race was not a predictor of metastases or other adverse outcomes. The current findings suggest that research efforts to understand racial differences in prostate cancer biology should focus on early stages of the disease (ie, closer to the time of diagnosis)

Validating the total illness burden index for prostate cancer (TIBI-CaP) in men with castration-resistant prostate cancer: data from TRUMPET
AIM:To validate the total illness burden index for prostate cancer (TIBI-CaP) in castration-resistant prostate cancer (CRPC) patients. PATIENTS & METHODS:Baseline comorbidity scores collected using the TIBI-CaP were compared with the baseline patient-reported health-related quality of life using the SF-12v2 and FACT-P questionnaires in 302 patients enrolled in the Treatment Registry for Outcomes in CRPC Patients (TRUMPET). RESULTS:Baseline TIBI-CaP scores were negatively correlated with all baseline SF-12v2 domain/composite (p < 0.001) and FACT-P subscale/total (p < 0.020) scores. There was a significant decreasing linear trend in SF12v2 and FACT-P scores over the categories based on TIBI-CaP quartiles of comorbidity burden (from 'least' to 'severe'). CONCLUSION:The TIBI-CaP is a valid measure of comorbidity burden in patients with CRPC in the real world
