Background: People with HIV (PWH) diagnosed with stage-IV cancer are less likely to receive palliative care (PC) compared to those without HIV. Our objective was to evaluate inequities in PC receipt among PWH with stage IV cancer in the US.

Methods: We used the National Cancer Database (2004-2020), including adult (18-89 years) PWH with the 14 most common cancers that occur among PWH. PC was defined as treatment provided with non-curative intent. Our main exposures included % quartiles of adults without a high school degree (educational attainment) and median income quartiles within the patient's zip code. We used hierarchical multivariable Poisson regression to estimate adjusted prevalence ratios(aPR) with 95% confidence intervals (95% CI), adjusting for age, sex, year of diagnosis, race/ethnicity, and cancer type.

Results: Among the included 10,120 PWH with stage IV cancer, 72% were men, 51% were either non-Hispanic(NH)-Black or Hispanic/Latinx, 38% were aged ≥60 years, and 97% resided in urban areas. Fourteen percent received PC. NH-Black PWH living in zip-codes with lower quartiles of educational attainment were more likely to receive PC compared to those in the highest quartile (Q1vs.Q4: aPR:1.93;95% CI:1.29-2,86) For income overall, compared to those in the highest quartile (Q4) of income, those in the lowest quartile had 26% higher likelihood of receiving PC (Q1vs.Q4: aPR:1.26;95% CI:1.05-1.52), particularly among NH-Black adults (Q1vs.Q4: aPR:1.67;95% CI:1.25-2.22; Q2 vs.Q4; aPR:1.48;95% CI:1.09-2.01).

Conclusions: PC use among PWH with stage-IV cancer is low. Contextual poverty plays a role in PC delivery to PWH and cancer, particularly among NH-Black PWH.

Background: In metastatic colorectal cancer (mCRC), improvements in survival from combining leucovorin/fluorouracil/oxaliplatin/irinotecan (FOLFOXIRI) with bevacizumab have come at the risk of increased rates of high-grade toxicities. Trilaciclib is indicated to decrease the incidence of chemotherapy-induced myelosuppression in patients receiving standard-of-care chemotherapy for extensive-stage small cell lung cancer.

Methods: Patients with untreated mCRC were randomized 1:1 to trilaciclib (n = 164) or placebo (n = 162) prior to FOLFOXIRI/bevacizumab for up to 12 cycles (induction), followed by trilaciclib or placebo prior to fluorouracil/leucovorin/bevacizumab (maintenance). Co-primary endpoints were duration of severe (grade 4) neutropenia (DSN) in cycles 1-4 and occurrence of severe neutropenia (SN) during induction. Secondary endpoints included antitumor efficacy, survival, and safety.

Results: : The study met its co-primary endpoints. Administering trilaciclib prior to FOLFOXIRI/bevacizumab resulted in significant reductions in DSN in cycles 1-4 versus placebo (mean, 0.1 vs. 1.3 days; P < .001) and occurrence of SN during induction (1.3% vs. 19.7%; adjusted relative risk [96% CI], 0.07 [0.0, 0.3]; P < .001). Grade 3/4 adverse events, including neutropenia, diarrhea, and leukopenia, were less frequent with trilaciclib versus placebo (64.8% vs. 73.1%). Trilaciclib was associated with fewer chemotherapy dose reductions and delays, and reduced administration of supportive therapies, compared with placebo. Objective response rate (41.6% vs. 57.1%; P = .009) and median progression-free survival (10.3 vs. 13.1 months; P < .001) were significantly lower with trilaciclib versus placebo.

Conclusions: : Administering trilaciclib prior to FOLFOXIRI/bevacizumab protected the neutrophil lineage from the effects of chemotherapy-induced myelosuppression. However, antitumor efficacy endpoints favored placebo.

Background: Socio-economic and demographical factors contribute to disparity in prostate cancer (PCa) outcomes. We examined the impact of area of deprivation index (ADI) and race on PCa incidence and lethality in a North-American cohort.

Methods: Our cohort included men who received at least one PSA test within our Health System (1995-2022). An ADI score was assigned to each patient based on their residential census block, ranked as a percentile of deprivation relative to the national level. Individuals were further categorized into quartiles, where the fourth one (ADI 75-100) represented those living in the most deprived areas. We investigated PCa incidence and lethality, using cumulative incidence estimates and competing-risk regression. An ADIxRace interaction term examined whether the relationship between ADI and outcomes varied based on race.

Results: We included 134,366 patients, 25% of whom were NHB. Median (IQR) follow-up was 8.8 (5-17) years. At multivariate analysis, individuals from the third (ADI 50-74, 95% CI: 0.83-0.95) and the fourth quartile (ADI ≥ 75, 95% CI: 0.75-0.86) showed significant reduced HRs for PCa incidence, when compared with the first quartile (ADI < 25, all p < .001). In contrast to the overall cohort, PCa incidence increased with ADI in NHB men, who were persistently at higher hazard for both PCa incidence and lethality than NHW, across all ADI strata (all p < .001).

Conclusions: Living in more deprived areas was associated with lower PCa incidence and higher lethal disease rate. Conversely, PCa incidence increased with ADI for NHB, who consistently showed worse outcomes than NHW individuals, regardless of ADI.

Background: Despite evidence of the benefit of routine cancer screenings, data show a concerning decline in cancer screening uptake for multiple cancer screenings. This analysis aimed to examine rural-urban differences in recent trends for being up to date with screenings for breast, cervical, and colorectal cancers.

Methods: We used 2018, 2020, and 2022 Behavioral Risk Factor Surveillance System data to assess up-to-date cancer screening status among eligible U.S. adults. We calculated weighted prevalence estimates overall and stratified by county-level rural-urban classification. We used survey-weighted multivariable logistic regression models to examine rural-urban disparities in cancer screening up-to-date status by year.

Results: Prevalence of being up to date with each cancer screening was lower in 2022 than it was in 2018. The largest decline in screening overall was for cervical cancer that dropped from 81.89% in 2018 to 47.71% in 2022. Rural-urban disparities were observed for breast cancer screening from 2018 to 2022 with the odds of up-to-date screening being 14% to 27% lower for rural populations than urban populations. For colorectal and cervical cancer, the odds of being up to date with screenings were lower for rural populations in 2018 and 2020, but there was no significant difference observed in 2022 (colorectal screening OR = 0.96; 95% CI: 0.90, 1.02) (cervical screening OR = 0.97; 95% CI: 0.93, 1.03).

Discussion: There is a concerning trend of decreasing uptake of cancer screenings, which will challenge future efforts in cancer prevention and control efforts. Efforts are needed to better understand factors contributing to the declining uptake of cancer screenings.

Background: In patients with diabetes mellitus (DM) and monoclonal gammopathy of undetermined significance (MGUS), the impact of GLP-1 receptor agonists (GLP-1RAs) on the natural history of MGUS is unknown. We aimed to assess the association of GLP-1RA use in the progression of MGUS to multiple myeloma (MM) in patients with DM.

Methods: This is a population-based cohort study of Veterans diagnosed with MGUS from 2006-2021 with a prior diagnosis of DM. A validated natural language processing-algorithm was used to confirm MGUS and progression to MM. Gray's test was performed to detect the difference in cumulative Incidence functions (CIFs) for progression by GLP-1RA use status. The association between time-varying GLP-1RA use and progression was estimated in the 1 (exposed):2 (unexposed) matched cohort via multivariable-adjusted hazard ratio (aHR) using stratified Fine-Gray distribution hazard model with death as a competing event and stratum for the matched patient triad.

Results: Our analytic cohort included 1,097 MGUS patients who ever used GLP-1RAs, and the matched 2,194 patients who never used GLP-1RAs. Overall, 2.55% progressed in the GLP-1RA ever use group, compared to 5.01% in the GLP-1RA never use group. CIFs were significantly different between the exposed and unexposed groups (P = .02). GLP-1RA use, compared to no-use, was associated with decreased progression to MM (aHR 0.45, 95% confidence interval 0.22 to 0.93, P = .03).

Conclusions: For patients with DM and MGUS, GLP-1RA use is associated with a 55% reduction in risk of progression from MGUS to MM, compared to no use.

Background: Young women with breast cancer (YWBC) face unique challenges that can impact their sexual health. This study aimed to identify factors associated with sexual activity, function, and satisfaction in YWBC up to five years post-diagnosis.

Methods: We conducted a prospective cohort study of 474 women aged ≤40 years diagnosed with non-metastatic breast cancer in Mexico. Sexual function and satisfaction were assessed using the Female Sexual Function Index and the Sexual Satisfaction Inventory, respectively. Factors associated with sexual health outcomes were examined using mixed-effects models.

Results: The prevalence of sexual dysfunction increased from 33.6% at baseline to 52.9% at 4-5 years post-diagnosis. Factors associated with worse sexual function included older age (mean predicted FSFI score -1.35, p = .037), treatment-induced amenorrhea (-2.86, p < .001), depression (-4.11, p < .001), and anxiety (-2.13, p < .001). Lower sexual satisfaction was associated with lower educational attainment (mean predicted SSI score -5.61, p = .002), being single (-6.41, p < .001), treatment induced amenorrhea (-3.76, p = .004), bilateral oophorectomy (-8.21, p = .017), depression (-11.29, p < .001), and anxiety (-7.50, p < .001). Quality of life, body image, and systemic therapy side effects significantly impacted both outcomes. Three distinct trajectories of sexual function were identified: high (62.2%), intermediate (24.3%), and markedly declining (13.5%). Four trajectories of sexual satisfaction were found, ranging from intermediate-to-high (57.3%) to progressively worsening (27.5%).

Conclusion: Sexual dysfunction is prevalent and persistent among YWBC. Multiple biological, psychological, and social factors influence sexual health outcomes in this population. These findings highlight the importance of routine screening and tailored interventions to address the sexual health of YWBC throughout survivorship.

Background: Local conditions where people live continue to influence prostate cancer outcomes. By examining local characteristics associated with trends in Black-White differences in prostate cancer specific mortality (PCSM) over time, we aim to identify factors driving county-level PCSM disparities over a 15-year period.

Methods: We linked county-level data (Area Health Resource File) with clinicodemographic data of men with prostate cancer (Surveillance, Epidemiology, and End Results registry) from 2005 to 2020. Generalized linear mixed models evaluated associations between race and county-level age-standardized PCSM, adjusting for age, year of death, rurality, and county-level education, income, uninsured rates, and densities of urologists, radiologists, primary care providers, and hospital beds.

Results: 185,390 patients in 1085 counties were identified, of which 15.8% were non-Hispanic Black. Racial disparities in PCSM narrowed from 2005 to 2020 (25.4 per 100,000 to 19.2 per 100,000 overall; 57.9 per 100,000 to 38 per 100,000 for Non-Hispanic Black patients and 23.4 per 100,000 to 18.3 per 100,000 for Non-Hispanic White patients). For both Non-Hispanic Black and Non-Hispanic White patients, county PCSM changes varied greatly (-65% to + 77% and -61% to + 112%, respectively). From 2016 to 2020, Non-Hispanic Black harbored greater PCSM risk (RR 2.09, 95% CI 2.01-2.18); higher radiation oncologist density was significantly associated with lower mortality risk (RR 0.93, 95% CI 0.89-0.98) while other provider densities were not.

Conclusion: Although overall rates improved, specific counties experienced worsening race-based disparities over time. Identifying locations of highest (and lowest) mortality disparities remains critical to development of location-specific solutions to racial disparities in prostate cancer outcomes.

Recent studies have shown that de novo metastatic prostate cancer incidence in the United States increased from 2010 to 2019. Plausible explanations include delayed detection after recommendations against prostate cancer screening or upstaging associated with use of more sensitive imaging technologies. Using Surveillance, Epidemiology, and End Results patient cases and controlling for aging of the population, we found the median age and prostate-specific antigen (PSA) level at prostate cancer diagnosis increased by 1.4 years of age (95% CI = 1.3 to 1.5 years) and 1.4 ng/mL (95% CI = 1.4 to 1.5 ng/mL) over this period, consistent with the delayed detection hypothesis. Racial differences were noted, with 75th percentiles of PSA at diagnosis increasing by 4.3 ng/mL (95% CI = 3.7 to 4.8 ng/mL) over this time period for non-Hispanic Black men compared with 3.0 ng/mL (95% CI = 2.8 to 3.2 ng/mL) for non-Hispanic White men. Overall, patient characteristics at diagnosis suggest that delayed detection contributed at least in part to increases in de novo metastatic disease.

Background: Posttreatment surveillance affects millions of cancer survivors, but empiric data to guide clinical practice are lacking. This study assessed whether the intensity of surveillance testing after radical prostatectomy or radiation therapy for localized prostate cancer is associated with overall survival.

Methods: Men diagnosed with localized prostate cancer between 2005 and 2010 who underwent radical prostatectomy or radiation therapy at a Commission on Cancer-accredited facility were randomly sampled. Primary data collected from 10 147 patients sampled across 1007 facilities were linked with existing data from the National Cancer Database. Analysis examined whether intensity of surveillance measured as the number of prostate-specific antigen (PSA) tests in the first year after primary treatment (categorized as 0-1 [low intensity], 2 [medium], or ≥3 [high intensity] PSA tests) was associated with overall survival. Secondary outcomes included recurrence-free survival (RFS) and subsequent use of imaging tests, biopsy procedures, and salvage treatment.

Results: Median follow-up exceeded 8 years from prostate cancer diagnosis. Overall survival was not statistically significantly different across surveillance intensity groups among radiation therapy (P = .59) or radical prostatectomy (P = .29) patients. RFS was not statistically significantly different across surveillance intensity groups for radiation therapy (P = .13) patients but was for radical prostatectomy (P = .01) patients with high intensity associated with the worst RFS. In both treatments, higher surveillance intensity was associated with more procedures and salvage treatments.

Conclusions: In patients with localized prostate cancer, more frequent PSA surveillance testing after radical prostatectomy or radiation therapy was associated with increased procedures and salvage treatments but not overall survival.

Background: Chemo-immunotherapy is standard of care for women with recurrent or advanced mismatch repair deficient endometrial carcinoma. However, it is uncertain whether patients with mismatch repair deficient advanced or recurrent endometrial carcinoma derive less benefit from chemotherapy than those with mismatch repair proficient endometrial carcinoma.

Methods: We performed a meta-analysis of randomized controlled trials (RCTs) in advanced or recurrent endometrial carcinoma to determine the difference in the benefit of chemotherapy in mismatch repair deficient vs mismatch repair proficient endometrial carcinoma. Data on chemotherapy outcomes including objective response rate, progression-free survival (PFS), and overall survival were retrieved. We pooled these data using the inverse variance method and examined subgroup difference by mismatch repair status. We also compared differences in PFS and overall survival outcomes by creating individual patient data from the Kaplan-Meier curves of trial publications for sensitivity analyses.

Results: A total of 5 RCTs with 1137 participants (mismatch repair deficient, 26%; mismatch repair proficient, 74%) were included. All participants were treated with carboplatin-based chemotherapy. There was no difference between the mismatch repair deficient and mismatch repair proficient subgroups for objective response rate (66.5% vs 64.0%; P = .20 for subgroup difference), PFS (hazard ratio [HR] = 0.93, 95% confidence interval [CI] = 0.77 to 1.12; P = .44; median PFS = 7.6 vs 9.5 months) or overall survival (HR = 1.03, 95% CI = 0.73 to 1.44; P = .88; median overall survival = not reached vs 28.6 months).

Conclusions: Objective response rate, PFS, and overall survival were similar among those with mismatch repair deficient vs mismatch repair proficient endometrial cancer treated with front-line, platinum-doublet chemotherapy in RCTs. These findings reinforce the importance of combining chemotherapy together with immune checkpoint inhibitors until the results of trials comparing immune checkpoint therapy alone with combination therapy are available.
