ABSTRACT

BACKGROUND: Chemohormonal therapy with androgen deprivation therapy and docetaxel (ADT + D) improves overall survival (OS) and quality of life (QOL) at 12 mo versus androgen deprivation therapy (ADT) alone in men with metastatic hormone-sensitive prostate cancer (mHSPC). However, the prognostic role of QOL is unknown in this population. OBJECTIVE: To study the relationship between QOL, disease characteristics, and OS in men with mHSPC. DESIGN, SETTING, AND PARTICIPANTS: In this exploratory post hoc analysis, 790 patients with mHSPC completed the QOL instruments Functional Assessment of Cancer Therapy-Prostate (FACT-P), Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F), and Brief Pain Inventory (BPI). OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Log-rank test and Cox proportional hazard models tested the association between QOL and OS by clinical and disease characteristics. RESULTS AND LIMITATIONS: Baseline higher FACT-P trended toward improved survival after accounting for clinical variables (hazard ratio [HR] 0.80 [0.62, 1.04], p = 0.09), while higher 3-mo FACT-P was independently associated with better survival (HR 0.76 [0.58, 1.0], p = 0.05). Patients with the poorest QOL (bottom quartile) at baseline and 3 mo had longer survival if they received ADT + D rather than ADT alone (median OS 45.2 vs 34.4 mo, HR 0.75 [0.53, 1.05], p = 0.09, and 48.3 vs 29.3 mo, HR 0.69 [0.48, 0.99], p = 0.05 respectively). In contrast, patients with the best QOL (top quartile) at baseline and 3 mo had comparable survival irrespective of whether or not docetaxel was added (median OS 72.1 vs 51.7 mo, HR 0.92 [0.63, 1.36], p = 0.69, and 69.9 vs 68.9 mo, HR 1.11 [0.73, 1.67], p = 0.63, respectively). Survival was linked with baseline FACIT-F (HR 0.76 [0.57, 1.0], p = 0.05), but not BPI (HR 0.98 [0.75, 1.28], p = 0.90). CONCLUSIONS: Three-month QOL had a stronger independent association with survival. The most symptomatic patients had longer survival with the addition of docetaxel; conversely, the least symptomatic patients did not appear to benefit. Consideration of QOL may enhance decision-making and patient selection when choosing chemohormonal treatment in mHSPC. PATIENT SUMMARY: Quality of life independently forecasted the survival of men with metastatic hormone-sensitive prostate cancer in the CHAARTED study. Close tracking of quality of life could help patients and clinicians make decisions about the appropriate treatment in this setting.

ABSTRACT

BACKGROUND AND OBJECTIVE: Neoadjuvant cisplatin-based chemotherapy prior to radical cystectomy (RC) improves overall survival (OS) in muscle-invasive bladder cancer (MIBC). However, many patients are cisplatin ineligible; therefore, new treatment options are needed. Nivolumab without/with lirilumab prior to RC was investigated in cisplatin-ineligible patients in this phase 1b trial (NCT03532451) to determine its safety/feasibility. METHODS: Patients with localized MIBC received two doses of nivolumab (480 mg) alone (cohort 1) or with lirilumab (240 mg; cohort 2) prior to RC. Cohorts were enrolled sequentially. The key eligibility criteria were cT2-4aN0-1M0 stage and cisplatin ineligibility/refusal. The primary endpoint was the rate of grade (G) ≥3 treatment-related adverse events (TRAEs) as per Common Terminology Criteria for Adverse Events version 5.0. The key secondary endpoints included the proportion of patients who underwent RC >6 wk after the last dose, CD8+ T-cell density change between pretreatment transurethral resection of bladder tumor (TURBT) and post-treatment RC, ypT0N0, 6 wk. In cohorts 1 and 2, ypT0N0 rates for patients with MIBC and RC were 17% and 21%,

ABSTRACT

Purpose: To examine circulating tumor DNA (ctDNA) and its association with residual cancer burden (RCB) using an ultrasensitive assay in patients with triple-negative breast cancer (TNBC) receiving neoadjuvant chemotherapy (NAT). Patients and Methods: We identified responders (RCB-0/1) and matched non-responders (RCB-2/3) from the phase II TBCRC 030 prospective study of neoadjuvant paclitaxel vs. cisplatin in TNBC. We collected plasma samples at baseline, three weeks, and twelve weeks (end of therapy). We created personalized ctDNA assays utilizing MAESTRO mutation enrichment sequencing. We explored associations between ctDNA and RCB status and disease recurrence. Results: Of 139 patients, 68 had complete samples and no additional NAT. Twenty-two were responders and 19 of those had sufficient tissue for whole-genome sequencing. We identified an additional 19 non-responders for a matched case-control analysis of 38 patients using a MAESTRO ctDNA assay tracking 319-1000 variants (median 1000) to 114 plasma samples from 3 timepoints. Overall, ctDNA positivity was 100% at baseline, 79% at week 3, and 55% at week 12. Median tumor fraction (TFx) was 3.7 × 10 -4 (range: 7.9 × 10 -7 to 4.9 × 10 -1 ). TFx decreased 285-fold from baseline to week 3 in responders and 24-fold in non-responders. Week 12 ctDNA clearance correlated with RCB: clearance was observed in 10/11 patients with RCB-0, 3/8 with RCB-1, 4/15 with RCB-2, and 0/4 with RCB-3. Among 6 patients with known recurrence five had persistent ctDNA at week 12. Conclusion: NAT for TNBC reduced ctDNA TFx by 285-fold in responders and 24-fold in non-responders. In 58% (22/38) of patients, ctDNA TFx dropped below the detection level of a commercially available test, emphasizing the need for sensitive tests. Additional studies will determine if ctDNA-guided approaches can improve outcomes.

ABSTRACT

OBJECTIVE: This study is a follow-up to a study in 2020 that reviewed changes in the racial and ethnic composition of public health students, graduates, and faculty among Association of Schools and Programs of Public Health (ASPPH)-member institutions. In the current study, we evaluated how the racial and ethnic composition among biostatistics and epidemiology students, graduates, and faculty changed from 2010 to 2020. METHODS: We analyzed data on race and ethnicity of enrolled graduate students, graduates (master's and doctoral), and faculty at ASPPH-member institutions by using institutionally reported data from the ASPPH Data Center. We tabulated frequencies, percentages, and percentage-point changes by race and ethnicity. We measured differences between groups by using a test for difference in 2 proportions. RESULTS: The number of enrolled students, graduates, and faculty in all departments increased during the study period, while the number of tenure-track faculty in biostatistics decreased. The percentage of enrolled Hispanic/Latino biostatistics graduate students increased from 5.6% in 2010 to 10.2% in 2020 (P = .007), and the percentage of epidemiology graduates increased from 8.8% to 13.8% (P = .008). We found no differences among other underrepresented racial and ethnic groups. Most biostatistics and epidemiology professors at all ranks were non-Hispanic White, despite substantial decreases. The percentage of underrepresented racial and ethnic minority biostatistics and epidemiology professors was constant across all ranks. CONCLUSION: Although more Hispanic/Latino students are enrolled in and graduating from biostatistics and epidemiology departments at ASPPH-member institutions, we found no change among faculty. More work is needed to recruit and retain other (American Indian/Alaska Native, Black or African American, Native Hawaiian/Other Pacific Islander) underrepresented students and faculty.

ABSTRACT

OBJECTIVE: To evaluate messages about infant feeding on breastmilk substitute (BMS) manufacturer websites directed at US caregivers and compare information and portrayals of breast-feeding/breastmilk with that of infant formula (IF) feeding. DESIGN: We conducted a content analysis of US BMS companies' websites. A codebook was created through an iterative process to identify messages and images about breast-feeding/breastmilk and IF feeding, including benefits or issues associated with each, and direct-to-consumer marketing practices that could discourage breast-feeding. SETTING: Data were collected in 2019-2020 and analysed in 2020-2021 for US websites of five IF manufacturers. PARTICIPANTS: The websites of Similac, Enfamil and Gerber, which collectively represent approximately 98 % of the US IF market, and two US organic brands, Earth's Best and Happy Baby. RESULTS: Websites contained more messages about breast-feeding/breastmilk than IF but were significantly more likely to mention benefits to baby of IF (44 %) than breast-feeding/breastmilk (<26 %), including significantly more statements that IF provides brain, neural and gastrointestinal benefits; 40 % of breast-feeding/breastmilk content was dedicated to breast-feeding problems (e.g. sore nipples). Twice as many screenshots compared IF brands favourably to breastmilk than as superior to other brands. Certain companies displayed images indicating ease of IF feeding and difficulty of breast-feeding. CONCLUSIONS: Substantial messaging on BMS manufacturer websites encouraged IF feeding and discouraged breast-feeding. Health professionals should discourage their patients from visiting these websites and the US government should regulate misleading claims. Companies should refrain from providing breast-feeding advice and align their US marketing with the International Code of Marketing of Breast-milk Substitutes.

ABSTRACT

Importance: Clinical decision support (CDS) algorithms are increasingly being implemented in health care systems to identify patients for specialty care. However, systematic differences in missingness of electronic health record (EHR) data may lead to disparities in identification by CDS algorithms. Objective: To examine the availability and comprehensiveness of cancer family history information (FHI) in patients' EHRs by sex, race, Hispanic or Latino ethnicity, and language preference in 2 large health care systems in 2021. Design, Setting, and Participants: This retrospective EHR quality improvement study used EHR data from 2 health care systems: University of Utah Health (UHealth) and NYU Langone Health (NYULH). Participants included patients aged 25 to 60 years who had a primary care appointment in the previous 3 years. Data were collected or abstracted from the EHR from December 10, 2020, to October 31, 2021, and analyzed from June 15 to October 31, 2021. Exposures: Prior collection of cancer FHI in primary care settings. Main Outcomes and Measures: Availability was defined as having any FHI and any cancer FHI in the EHR and was examined at the patient level. Comprehensiveness was defined as whether a cancer family history observation in the EHR specified the type of cancer diagnosed in a family member, the relationship of the family member to the patient, and the age at onset for the family member and was examined at the observation level. Results: Among 144 484 patients in the UHealth system, 53.6% were women; 74.4% were non-Hispanic or non-Latino and 67.6% were White; and 83.0% had an English language preference. Among 377 621 patients in the NYULH system, 55.3% were women; 63.2% were non-Hispanic or non-Latino, and 55.3% were White; and 89.9% had an English language preference. Patients from historically medically undeserved groups-specifically, Black vs White patients (UHealth: 17.3% [95% CI, 16.1%-18.6%] vs 42.8% [95% CI, 42.5%-43.1%]; NYULH: 24.4% [95% CI, 24.0%-24.8%] vs 33.8% [95% CI, 33.6%-34.0%]), Hispanic or Latino vs non-Hispanic or non-Latino patients (UHealth: 27.2% [95% CI, 26.5%-27.8%] vs 40.2% [95% CI, 39.9%-40.5%]; NYULH: 24.4% [95% CI, 24.1%-24.7%] vs 31.6% [95% CI, 31.4%-31.8%]), Spanish-speaking vs English-speaking patients (UHealth: 18.4% [95% CI, 17.2%-19.1%] vs 40.0% [95% CI, 39.7%-40.3%]; NYULH: 15.1% [95% CI, 14.6%-15.6%] vs 31.1% [95% CI, 30.9%-31.2%), and men vs women (UHealth: 30.8% [95% CI, 30.4%-31.2%] vs 43.0% [95% CI, 42.6%-43.3%]; NYULH: 23.1% [95% CI, 22.9%-23.3%] vs 34.9% [95% CI, 34.7%-35.1%])-had significantly lower availability and comprehensiveness of cancer FHI (P < .001). Conclusions and Relevance: These findings suggest that systematic differences in the availability and comprehensiveness of FHI in the EHR may introduce informative presence bias as inputs to CDS algorithms. The observed differences may also exacerbate disparities for medically underserved groups. System-, clinician-, and patient-level efforts are needed to improve the collection of FHI.
