Association Between Sleep Apnea Treatment and Health Care Resource Use in Patients With Atrial Fibrillation.

BACKGROUND: Obstructive sleep apnea (OSA) contributes to the generation, recurrence, and perpetuation of atrial fibrillation, and it is associated with worse outcomes. Little is known about the economic impact of OSA therapy in atrial fibrillation. This retrospective cohort study assessed the impact of positive airway pressure (PAP) therapy adherence on health care resource use and costs in patients with OSA and atrial fibrillation. METHODS AND RESULTS: Insurance claims data for ≥1 year before sleep testing and 2 years after device setup were linked with objective PAP therapy use data. PAP adherence was defined from an extension of the US Medicare 90-day definition. Inverse probability of treatment weighting was used to create covariate-balanced PAP adherence groups to mitigate confounding. Of 5867 patients (32% women; mean age, 62.7 years), 41% were adherent, 38% were intermediate, and 21% were nonadherent. Mean±SD number of all-cause emergency department visits (0.61±1.21 versus 0.77±1.55 [P=0.023] versus 0.95±1.90 [P<0.001]), all-cause hospitalizations (0.19±0.69 versus 0.24±0.72 [P=0.002] versus 0.34±1.16 [P<0.001]), and cardiac-related hospitalizations (0.06±0.26 versus 0.09±0.41 [P=0.023] versus 0.10±0.44 [P=0.004]) were significantly lower in adherent versus intermediate and nonadherent patients, as were all-cause inpatient costs ($2200±$8054 versus $3274±$12 065 [P=0.002] versus $4483±$16 499 [P<0.001]). All-cause emergency department costs were significantly lower in adherent and intermediate versus nonadherent patients ($499±$1229 and $563±$1292 versus $691±$1652 [P<0.001 and P=0.002], respectively). CONCLUSIONS: These data suggest clinical and economic benefits of PAP therapy in patients with concomitant OSA and atrial fibrillation. This supports the value of diagnosing and managing OSA and highlights the need for strategies to enhance PAP adherence in this population.

Healthcare resource utilisation and costs in patients with treated obstructive sleep apnea.

Obstructive sleep apnea (OSA) is a highly prevalent yet underdiagnosed disease that creates a large economic burden on the United States healthcare system. In this retrospective study, we tested the hypothesis that adherence to positive airway pressure (PAP) therapy, the 'gold standard' treatment for OSA, is associated with reduced healthcare resource utilisation and costs. We linked de-identified payer-sourced medical claims and objective PAP usage data for patients newly diagnosed with OSA. Inverse probability of treatment weighting was used to create balanced groups of patients who were either adherent, intermediately adherent, or non-adherent to PAP therapy. From a sample of 179,542 patients (average age 52.5 years, 61% male), 37% were adherent, 40% intermediate, and 23% non-adherent. During the first year, PAP adherence was significantly associated with fewer emergency room visits (mean [SD] adherent: 0.39 [1.20] versus intermediate: 0.47 [1.30], p < 0.001; versus non-adherent: 0.54 [1.44], p < 0.001), all-cause hospitalisations (mean [SD] adherent: 0.09 [0.43] versus intermediate: 0.12 [0.51], p < 0.001; versus non-adherent: 0.13 [0.55], p < 0.001), and lower total costs (mean [SD] adherent $5874 [8045] versus intermediate $6523 [9759], p < 0.001; versus non-adherent $6355 [10,517], p < 0.001). Results were similar in the second year of PAP use. These results provide additional evidence from a large, diverse sample to support the diagnosis and treatment of OSA and encourage long-term adherence to PAP therapy.

Blood inflammatory markers and mortality in the US population: A Health and Retirement Survey (HRS) analysis.

A potential direct correlation between systemic inflammation and physiological aging has been suggested, along with whether there is a higher expression of inflammatory markers in otherwise healthy older adults. Cross-sectional data were extracted from the publicly available 2016 Health and Retirement Survey, a nationally representative survey of older adults in the United States. A subset of participants (n = 9934) consented to a blood draw at the time of recruitment and were measured for high sensitivity C-reactive protein (hs-CRP), Interleukin (IL-6, IL-10, IL-1RA), soluble tumor necrosis factor receptor (sTNFR-1) and transforming growth factor beta 1 (TGF-ß1). We included 9,188 participants, representative of 83,939,225 nationally. After adjusting for sex and the number of comorbidities, there remained a significant positive correlation between age and ln (log adjusted) IL-6, and ln sTNFR-1, and a significant inverse correlation between age and ln IL-1RA, ln TGF-ß1, and ln hs-CRP. Among the subset of participants who reported none of the available comorbidities (n = 971), there remained an independent correlation of age with ln IL-6 and ln sTNFR-1. After adjusting for age, sex, and number of reported comorbidities, there was a statistically significant correlation between increased ln IL-6, ln IL-10, ln sTNFR-1, and ln hs-CRP with death. This study highlights the existence of a correlation between serum biomarkers of inflammation and aging, not only in the whole population, but also in the smaller subset who reported no comorbidities, confirming the existence of a presence of low-grade inflammation in aging, even in healthy elders. We also highlight the existence of a correlation between inflammatory markers and overall mortality. Future studies should address a possible threshold of systemic inflammation where mortality significantly increases, as well as explore the effectiveness of anti-inflammatory treatments on morbidity and mortality in healthy aging subjects.

Personal and clinical characteristics associated with immunotherapy effectiveness in stage IV non-small cell lung cancer.

Background: Immunotherapy response rates in metastatic non-small cell lung cancer (NSCLC) are low and survival varies significantly. Factors like age, sex, race, and histology may modulate immunotherapy response. Existing analyses are limited to clinical trials, with limited generalizability, and meta-analyses where adjustment for potential confounders cannot be performed. Here, we conduct a cohort study with patient-level analysis to explore how personal and clinical characteristics moderate chemoimmunotherapy effectiveness in metastatic NSCLC. Methods: Stage IV NSCLC patients diagnosed in 2015 were drawn from Surveillance Epidemiology, and End Results-Medicare linked data. Receipt of chemoimmunotherapy and overall survival (OS) were the primary predictor and outcome of interest respectively. Multivariable Cox-proportional hazards regression and propensity-score matching were performed to evaluate the effectiveness of immunotherapy addition to chemotherapy. Results: From a total of 1,471 patients, 349 (24%) received chemoimmunotherapy and 1,122 (76%) received chemotherapy alone. Survival was significantly better among those treated with chemoimmunotherapy compared to those receiving chemotherapy alone [adjusted hazard ratio (HRadj) =0.72, 95% confidence interval (CI): 0.63-0.83]. Males saw significantly better OS from chemoimmunotherapy (HRadj =0.62, 95% CI: 0.51-0.75) than females (HRadj =0.81, 95% CI: 0.65-1.01, Pinteraction=0.0557). After propensity-score matching, the effect of chemoimmunotherapy was borderline significant according to sex (Pinteraction =0.0414), but not age or histology. Conclusions: Males may benefit more from chemoimmunotherapy, but there is limited evidence suggesting age, histology, race, and comorbidities contribute to differences in effectiveness. Future research should elucidate who responds best to chemoimmunotherapy, and further analyses of characteristics like race can inform how to tailor different treatment regimens to distinct patient subpopulations.

Effect of stage shift and immunotherapy treatment on lung cancer survival outcomes.

OBJECTIVES: Non-small-cell lung cancer mortality has declined at a faster rate than incidence due to multiple factors, including changes in smoking behaviour, early detection which shifts diagnosis, and novel therapies. Limited resources require that we quantify the contribution of early detection versus novel therapies in improving lung cancer survival outcomes. METHODS: Non-small-cell lung cancer patients from the Surveillance, Epidemiology, and End Results-Medicare data were queried and divided into: (i) stage IV diagnosed in 2015 (n = 3774) and (ii) stage I-III diagnosed in 2010-2012 (n = 15 817). Multivariable Cox-proportional hazards models were performed to assess the independent association of immunotherapy or diagnosis at stage I/II versus III with survival. RESULTS: Patients treated with immunotherapy had significantly better survival than those who did not (HRadj: 0.49, 95% confidence interval: 0.43-0.56), as did those diagnosed at stage I/II versus stage III (HRadj: 0.36, 95% confidence interval: 0.35-0.37). Patients on immunotherapy had a 10.7-month longer survival than those who were not. Stage I/II patients had an average survival benefit of 34 months, compared to stage III. If 25%% of stage IV patients not on immunotherapy received it, there would be a gain of 22 292 person-years survival per 100 000 diagnoses. A switch of only 25% from stage III to stage I/II would correspond to 70 833 person-years survival per 100 000 diagnoses. CONCLUSIONS: In this cohort study, earlier stage at diagnosis contributed to life expectancy by almost 3 years, while gains from immunotherapy would contribute ½ year of survival. Given the relative affordability of early detection, risk reduction through increased screening should be optimized.

Trends in prostate cancer incidence among Black men in the Caribbean and the United States.

BACKGROUND: Prostate cancer incidence is highest for Black men of the African diaspora in the United States and Caribbean. Recent changes in recommendations for prostate cancer screening have been shown to decrease overall prostate cancer incidence and increase the likelihood of late stage disease. However, it is unclear how trends in prostate cancer characteristics among high risk Black men differ by geographic region during the changes in screening recommendations. METHODS: In this study, we used population-based prostate cancer registry data to describe age-adjusted prostate cancer incidence trends from 2008 to 2015 among Black men from six geographic regions. We obtained data on incident Black prostate cancer patients from six cancer registries (in the United States: Florida, Alabama, Pennsylvania, and New York; and in the Caribbean: Guadeloupe and Martinique). After age standardization, we used descriptive analyses to compare the demographics and tumor characteristics by cancer registry site. The Joinpoint regression program was used to compare the trends in incidence by site. RESULTS: A total of 59,246 men were analyzed. We found the highest incidence rates (per 100,000) for prostate cancer in the Caribbean countries (181.99 in Martinique and 176.62 in Guadeloupe) and New York state (178.74). Incidence trends decreased significantly over time at all sites except Martinique, which also showed significantly increasing rates of late stage (III/IV) and Gleason score 7+ tumors. CONCLUSIONS: We observed significant differences in prostate cancer incidence trends among Black men after major changes prostate screening recommendations. Future studies will examine the factors that differentially influence prostate cancer trends among the African diaspora.

Malignant pleural mesothelioma characteristics and outcomes: A SEER-Medicare analysis.

BACKGROUND: Pleural mesothelioma is rare cancer linked to asbestos exposure. Previous research has indicated that female individuals have better survival than male individuals, but this has never been examined in the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. MATERIALS AND METHODS: Malignant pleural mesothelioma cases diagnosed from 1992 to 2015 were queried from the linked SEER-Medicare database. Multivariable logistic regression was used to assess the clinical and demographic factors associated with sex. A multivariable Cox proportional hazards model and propensity matching methods were used to assess sex differences in overall survival (OS) while accounting for potential confounders. RESULTS: Among 4201 patients included in the analysis, 3340 (79.5%) were males and 861 (20.5%) females. Females were significantly older, with more epithelial histology than males were, and had significantly better OS, adjusted for confounders (adjusted hazard ratio, 0.83, 95% confidence interval: 0.76-0.90). Other variables independently associated with improved survival included younger age at diagnosis, having a spouse/domestic partner, epithelial histology, lower comorbidity score, and receipt of surgery or chemotherapy. CONCLUSIONS: The study describes sex differences in mesothelioma occurrence, treatment, and survival and is the first to examine SEER-Medicare. It provides directions for future research into potential therapeutic targets.

The Scan, the Needle, or the Knife? National Trends in Diagnosing Stage I Lung Cancer.

OBJECTIVE: Indeterminate lung nodules have been increasingly discovered since the expansion of lung cancer screening programs. The diagnostic approach for suspicious nodules varies based on institutional resources and preferences. The aim of this study is to analyze factors associated with diagnostic modalities used for early-stage non-small cell lung cancer (NSCLC). METHODS: The National Cancer Database was queried for all patients with stage I NSCLC from 2004 to 2015. Four diagnostic modalities were identified, including clinical radiography alone (CRA), bronchial cytology (BC), procedural biopsy (PB), and surgical biopsy (SB). A multivariable multinomial logistic regression was used to assess associations of patient demographics, cancer characteristics, and facility characteristics with these modalities. RESULTS: Of 250,614 patients, 4,233 (1.7%) had CRA, 5,226 (2.1%) had BC, 147,621 (59.9%) had PB, and 93,534 (37.3%) had SB. Older patients were more likely to receive CRA (adjusted odds ratio [ORadj] = 5.3) and less likely to receive SB (ORadj = 0.73). Black patients were less likely to receive SB (ORadj = 0.83) and more likely to receive BC (ORadj = 1.31). Private insurance was associated with SB (ORadj = 1.11), whereas Medicaid was associated with BC (ORadj = 1.21). Patients more than 50 miles from the facility were more likely to undergo SB (ORadj = 1.25 vs PB; ORadj = 1.30 vs CRA; ORadj = 1.38 vs BC). Patients receiving SB had shorter days from diagnosis to treatment (23.0 vs 53.5 to 64.7 for other modalities, P < 0.001). CONCLUSIONS: Diagnostic SB to confirm early-stage NSCLC was associated with younger age, greater travel distance, and shorter time to treatment in comparison with other modalities. Black race and non-private insurance were less likely to be associated with SB.

Methodological Considerations on COVID-19 Mortality in Cancer Patients: A Systematic Review and Meta-Analysis.

BACKGROUND: Patients with cancer are at risk for severe COVID-19. Previous studies examining mortality in cancer patients with COVID-19 have produced inconclusive results. Several published meta-analyses have aimed to estimate this association; however, because of methodological limitations in study selection and data aggregation, these studies do not reliably estimate the independent association between cancer and COVID-19 mortality. We conducted this systematic review and meta-analysis to determine whether cancer is an independent risk factor for COVID-19 mortality. METHODS: A literature search was performed in PubMed to identify studies that compared COVID-19 mortality in adult patients with and without cancer. Selection criteria included polymerase chain reaction-confirmed COVID-19, multivariate adjustment and/or matching for mortality risk estimates, and inclusion of hospitalized noncancer controls. Adjusted odds ratios and/or hazard ratios for mortality based on cancer status were extracted. Odds ratio and hazard ratio estimates were pooled using a random effects model. RESULTS: The analysis included 42 studies comprising 129 840 patients: 8612 cancer patients and 121 228 noncancer patients. Of these studies, 18 showed a null difference in survival between cancer and noncancer patients with COVID-19, and 24 studies showed statistically significantly worse survival in cancer patients with COVID-19. Meta-analysis revealed an increased risk of mortality in patients with cancer compared with noncancer patients with COVID-19 (odds ratio = 1.93, 95% confidence interval = 1.55 to 2.41; hazard ratio = 1.54, 95% confidence interval = 1.29 to 1.84). CONCLUSION: We conclude that cancer is an independent risk factor for mortality in unvaccinated patients admitted for or diagnosed with COVID-19 during hospitalization.

Association of Personal Characteristics and Effectiveness of Immunotherapy in Late-Stage Non-Small Cell Lung Cancer: A Systematic Review.

BACKGROUND: Although immunotherapy can increase survival in non-small cell lung cancer (NSCLC), response rates are low. It is unclear which characteristics contribute to variability in immunotherapy efficacy and survival. Research is needed to identify reasons for heterogeneity in response rates to better tailor treatments. METHODS: Web of Science, Ovid EMBASE, and MEDLINE were queried from 2013 to January 2021, and all studies reporting overall or progression-free survival for patients treated with immunotherapy for NSCLC of at least stage IIIB were screened. RESULTS: Included were 18 randomized controlled trials (RCTs; 6534 immunotherapy RCTs; 11 192 nonimmunotherapy RCTs) and 16 observational studies (n = 9073 immunotherapy patients). Among RCTs, there was improved survival with the addition of immunotherapy in patients aged younger than 65 years in 10 of 17 studies; smokers in 8 of 15 studies; and males in 10 of 17 studies and 6 of 17 females. Only 5 studies reported outcomes by race. Among observational studies, younger patients (aged younger than 60, younger than 65, or younger than 70 years in most studies) had better survival than older patients (aged 60 years and older, 65 years and older, or 70 years and older) in 4 of 13 studies, ever-smokers in 7 of 13, and females in 2 of 14. Three studies reported race with mixed results. CONCLUSION: Although evidence is mixed, younger patients, smokers, and males may derive more benefit from immunotherapy. Evidence on racial differences is limited. Physicians should be mindful of personal characteristics when formulating treatment plans. Further research is needed to understand underlying mechanisms and to identify the best immunotherapy candidates and alternative treatments for those unlikely to benefit.

Global DNA methylation of WTC prostate cancer tissues show signature differences compared to non-exposed cases.

There is increased incidence of prostate cancer (PC) among World Trade Center (WTC)-exposed responders and community members, with preliminary evidence suggestive of more aggressive disease. While previous research is supportive of differences in DNA methylation and gene expression as a consequence of WTC exposure, as measured in blood of healthy individuals, the epigenetics of WTC PC tissues has yet to be explored. Patients were recruited from the World Trade Center Health Program. Non-WTC PC samples were frequency matched on age, race/ethnicity and Gleason score. Bisulfite-treated DNA was extracted from tumor tissue blocks and used to assess global DNA methylation with the MethylationEPIC BeadChip. Differential and pathway enrichment analyses were conducted. RNA from the same tumor blocks was used for gene expression analysis to further support DNA methylation findings. Methylation data were generated for 28 samples (13 WTC and 15 non-WTC). Statistically significant differences in methylation were observed for 3,586 genes; on average WTC samples were statistically significantly more hypermethylated (P = 0.04131). Pathway enrichment analysis revealed hypermethylation in epithelial mesenchymal transition (EMT), hypoxia, mitotic spindle, TNFA signaling via NFKB, WNT signaling, and TGF beta signaling pathways in WTC compared to non-WTC samples. The androgen response, G2M and MYC target pathways were hypomethylated. These results correlated well with RNA gene expression. In conclusion, long-term epigenic changes associated with WTC dust exposure were observed in PC tissues. These occurred in genes of critical pathways, likely increasing prostate tumorigenesis potential. This warrants analysis of larger WTC groups and other cancer types.

Modulation of chemoimmunotherapy efficacy in non-small cell lung cancer by sex and histology: a real-world, patient-level analysis.

BACKGROUND: It has been postulated that patient's sex impacts response to immunotherapy. Sex modulation of immunotherapy benefit, however, has not yet been explored using patient-level data, where potential confounders, as well as histologic type, can be accounted for. Here we investigated the association between sex and chemoimmunotherapy efficacy for non-small cell lung cancer (NSCLC) using a large, nation-wide dataset. PATIENTS & METHODS: Stage IV NSCLC patients diagnosed in 2015 were identified in the National Cancer Database (NCDB). Patients were treated with either chemoimmunotherapy or chemotherapy alone. The efficacy of the addition of immunotherapy treatment by sex was investigated using both an adjusted Cox proportional hazards model and propensity-score matching, in both the overall cohort and stratified by histological subtype. RESULTS: 2064 (16%) patients received chemoimmunotherapy and10,733 (84%) received chemotherapy alone. Adjusted survival analysis in the overall cohort showed that both males (hazards ratio (HR)adj: 0.80, 95% CI: 0.74-0.87) and females (HRadj: 0.83, 95% CI: 0.76-0.90) had better OS when treated with chemoimmunotherapy than chemotherapy alone, with no statistically significant interaction between sex and receipt of immunotherapy (p = 0.63). Propensity matching confirmed these results. However, for those with squamous cell histology, male patients derived more benefit from chemoimmunotherapy treatment than females (HRadj: 0.73, 95% CI: 0.58-0.91 vs HRadj: 1.03, 95% CI: 0.76-1.38; p for interaction = 0.07). CONCLUSION: Male patients with squamous cell carcinoma may derive more benefit from chemoimmunotherapy treatment. Histology likely plays an important role in how sex modulates immunotherapy efficacy.

Disparities in clinical and demographic characteristics among Asian/Pacific Islander and Non-Hispanic White newly diagnosed lung cancer patients.

PURPOSE: Racial disparities persist among lung cancer patients but have not been adequately studied among Asian/Pacific Islander (API) subgroups, which are heterogeneous. This study compared clinical and demographic characteristics at diagnosis of API subgroups and NHW patients. METHODS: NHW and API adults diagnosed with lung cancer were identified from the Surveillance, Epidemiology, and End Results database (1990-2015). API was divided into eight subgroups: Chinese, Japanese, Filipino, Hawaiian/Pacific Islander, Korean, Vietnamese, Asian Indian/Pakistani, and Other. Multivariable multinomial logistic regression models were used to assess adjusted associations of clinical and demographic factors with API/subgroups. RESULTS: There were 522,702 (92.6%) NHW and 41,479 (7.4%) API lung cancer patients. API were less likely to be diagnosed at the age of ≥ 80 years (ORadj 0.53, 95% CI 0.48-0.58 for ≥ 80 vs. ≤ 39 years) than NHW. However, Japanese patients were more often diagnosed at ≥ 80 years compared to other ethnic subgroups. API were less often female (ORadj 0.85, 95% CI 0.83-0.86), and unmarried (ORadj 0.71, 95% CI 0.68-0.74); however, among API, Japanese, Hawaiian/Pacific Islander, Korean, and Vietnamese were more often unmarried, compared to Chinese patients. API were more frequently diagnosed at stage IV, compared to stage I (ORadj 1.31, 95% CI 1.27-1.35). API had significantly less squamous cell carcinoma (ORadj 0.54, 95% CI 0.52-0.56, compared to adenocarcinoma); among API, Japanese, Filipino, Hawaiian/Pacific Islander, Korean, Asian Indian/Pakistani, and Other were more likely than Chinese patients to present with squamous cell histology (range: ORadj[Other] 1.24, 95% CI 1.09-1.41; ORadj[Hawaiian/Pacific Islander] 2.47, 95% CI 2.22-2.75). CONCLUSION: At diagnosis, there are significant differences in demographic and clinical characteristics between NHW, API, and API subgroups. Treating API patients as a single population may overlook biological, environmental, and behavioral differences that might be beneficial in designing prevention strategies and treatment.

Trends for In- and Outpatient Thyroid Cancer Surgery in Older Adults in New York State, 2007-2017.

BACKGROUND: In view of the 2013 American Thyroid Association consensus statement on outpatient thyroidectomy, the present study assessed the trends and factors associated with thyroid cancer surgery setting in older adults, using the New York Statewide Planning and Research Cooperative System database. MATERIALS AND METHODS: There were 14,495 patients with surgically treated thyroid cancer in New York State between 2007 and 2017. Trends were plotted over time and stratified by surgery type. Significance of the trend was assessed using the Mann-Kendall test. Multivariable logistic regression was used to assess independent associations with surgical setting. RESULTS: The overall outpatient surgery rate significantly increased over time (correlation coefficient 0.82; P < 0.001), for both total thyroidectomy (P < 0.001) and lobectomy (P < 0.001). Factors associated with increased odds of inpatient surgery were medium- and high-volume hospitalization (adjusted odds ratio [ORadj] 2.12, 95% confidence interval [CI] 1.93-2.32; ORadj 1.69, 95% CI 1.55-1.85, respectively) versus low volume, undergoing total thyroidectomy (ORadj 1.75, 95% CI 1.61-1.90), as well as having Medicare insurance (ORadj 1.13, 95% CI 1.02-1.24) versus private insurance. CONCLUSIONS: The present study shows that outpatient thyroidectomy is increasingly favored over inpatient thyroidectomy over time in an older patient population. A clear changepoint following 2011 preceded the publication of the American Thyroid Association statement on outpatient thyroidectomy in 2013 and was likely associated with multiple publications reporting safety of outpatient thyroid surgery and clear economic benefits.

A national profile of health-focused caregiving activities prior to a new cancer diagnosis.

BACKGROUND: Little is known about how unpaid family caregivers may already be engaged in caregiving activities prior to their care recipient's cancer diagnosis. We examined pre-cancer diagnosis caregiving patterns and their association with caregiving strain. METHODS: We conducted a population-based analysis of 2011-2017 National Health and Aging Trends Study (NHATS) linked with the National Study of Caregiving (NSOC) and Medicare claims data. Latent class analysis was used to examine patterns of 16 health-focused caregiving tasks (e.g., tracking medications, making appointments) of family caregivers assisting adults ≥65 years prior to an incident cancer diagnosis. High caregiving strain was defined as a total score ≥ 85th percentile of 6 caregiving strain items (e.g., financial difficulty, no time for self). Association between caregiving patterns and strain were examined using multivariable logistic regression, adjusting for care recipient and caregiver characteristics. RESULTS: An estimated 4.2 million caregivers cared for older adults prior to care recipients' new cancer diagnoses during 2011-2017. They engaged in a median of four health-focused caregiving activities. Nearly 1-in-5 (18.7%) pre-cancer caregivers had high caregiving strain. Caregivers were classified into 3 health-focused caregiving activity classes: Low-level (41.2%), Moderate-coordination (29.3%), and High-intensity (29.4%). Higher caregiving activity was associated with higher caregiving strain (adjusted odds ratio (aOR) = 3.85, 95% CI: 2.34-6.33). Caregivers in the High-intensity class had the highest caregiving strain (39.9%), and included more spouses (28.1% vs <18%). CONCLUSION: One-third of U.S. caregivers who help older adults prior to their cancer diagnoses are already highly strained and engaged in high-level health-focused caregiving tasks. Oncology clinicians should assess the capacity and strain of family caregivers who may already be supporting patients with new cancer diagnoses and refer caregivers to additional supportive care services.

Patient-reported outcomes following total thyroidectomy and lobectomy in thyroid cancer survivors: an analysis of the PROFILES Registry data.

PURPOSE: Patient-reported outcomes are important in the surgical decision-making process for low-risk, differentiated thyroid cancer. Current study aimed to assess patient-reported outcomes in thyroid cancer survivors comparing total thyroidectomy (TT) and lobectomy (LT) using the Patient Reported Outcomes Following Initial treatment and Long term Evaluation of Survivorship (PROFILES) registry. METHODS: European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) scales, illness perception questions, Beliefs about Medicines Questionnaire (BMQ) scales and questions about thyroid surgery-related medication use were compared between thyroid cancer patients who underwent TT versus LT using descriptive analyses. RESULTS: In total, 58 thyroid cancer patients who underwent TT or LT were included in this study. None of the EORTC QLQ-C30 scales or questions regarding illness perception were significantly different between the surgical groups. Patients in the TT group had significantly higher belief in the necessity of their medication (21.0 vs 15.4; p = 0.003) and greater concerns about taking their medicines (14.7 vs 11.1; p = 0.008) versus patients in the LT group. CONCLUSION: Concerns about post-surgical medication use specifically in the TT group may indicate that clinicians should consider LT in patients with low-risk, differentiated thyroid cancer when LT and TT are viable surgical options. Clinicians should be aware of the impact of post-surgical medication use in particular following TT and use this knowledge to align goals of treatment with the extent of surgery, allowing for a better-informed decision-making process.

Association of Stage Shift and Population Mortality Among Patients With Non-Small Cell Lung Cancer.

Importance: Early detection by computed tomography and a more attention-oriented approach to incidentally identified pulmonary nodules in the last decade has led to population stage shift for non-small cell lung cancer (NSCLC). This stage shift could substantially confound the evaluation of newer therapeutics and mortality outcomes. Objective: To investigate the association of stage shift with population mortality among patients with NSCLC. Design, Setting, and Participants: This retrospective cohort study was performed from October 2020 to June 2021 and used data from the Surveillance, Epidemiology, and End Results (SEER) registries to assess all patients from 2006 to 2016 with NSCLC. Main Outcomes and Measures: Incidence-based mortality was evaluated by year-of-death. To assess shifts in diagnostic characteristics, clinical stage and histology distributions were examined by year using χ2 tests. Trends were assessed using the average annual percentage change (AAPC), calculated with JoinPoint software. Kaplan-Meier survival analysis assessed overall survival according to stage and compared those missing any stage with those with a reported stage. Results: The final sample contained 312 382 patients; 166 657 (53.4%) were male, 38 201 (12.2%) were Black, and 249 062 (79.7%) were White; the median (IQR) age was 68 (60-76) years; 163 086 (52.2%) had adenocarcinoma histology. Incidence-based mortality within 5 years of diagnosis decreased from 2006 to 2016 (AAPC, -3.7; 95% CI, -4.1 to -3.4). When assessing stage shift, there was significant association between year-of-diagnosis and clinical stage, with stage I/II diagnosis increasing from 26.5% to 31.2% (AAPC, 1.5; 95% CI, 0.5 to 2.5); and stage III/IV diagnosis decreasing significantly from 70.8% to 66.1% (AAPC, -0.6; 95% CI, -1.0 to -0.2). Missing staging information was not associated with year-of-diagnosis (AAPC, -1.6; 95% CI, -7.4 to 4.5). Year-of-diagnosis was significantly associated with tumor histology (χ2 = 8990.0; P < .001). There was a significant increase in adenocarcinomas: 42.9% in 2006 to 59.0% in 2016 (AAPC, 3.4; 95% CI, 2.9 to 3.9). Median (IQR) survival for stage I/II was 57 months (18 months to not reached); stage III/IV was 7 (2-19) months; and missing stage was 10 (2-28) months. When compared with those with known stage, those without stage information had significantly worse survival than those with stage I/II, with survival between those with stage III and stage IV (log-rank χ2 = 87 125.0; P < .001). Conclusions and Relevance: This cohort study found an association between decreased mortality and a corresponding diagnostic shift from later to earlier stage. These findings suggest that studies investigating the effect of treatment on lung cancer must take into account stage shift and the confounding association with survival and mortality outcome.

Trends of hospitalizations among patients with both cancer and dementia diagnoses in New York 2007-2017.

BACKGROUND: Cancer and dementia have often been studied in isolation. We aimed to examine the spatiotemporal trend of inpatient admissions with both cancer and dementia diagnoses. METHODS: Using state-wide inpatient claims data, we identified all hospital admissions for patients aged ≥50 years with both cancer and dementia diagnoses in New York State, 2007-2017. We examined the spatiotemporal trend of the admission using a novel Bayesian hierarchical model adjusting for socioeconomic factor, as measured by Yost index. RESULTS: Admissions with the presence of both cancer and dementia diagnoses represented 8.5% of all admissions with a cancer diagnosis, and the proportion increased from 7.1% in 2007 to 9.7% in 2017. The median admission rate was 3.5 (interquartile range: 2.2-5.2) hospitalizations per 1000 population aged ≥50 years, which increased from 2.9 in 2007 to 3.7 in 2017. The admission rate peaked first in 2010 followed by a smaller peak in 2014, before stabilizing at a level higher than the pre-2010 period. Taking into account the spatiotemporal heterogeneity, we found that hospitalizations among those with both cancer and dementia diagnoses were associated with a higher socioeconomic status (the posterior median relative risk for Yost index = 1.046 (95% credible interval: 1.033-1.058)). CONCLUSIONS: Hospitalizations of patients with both cancer and dementia increased over time. Cancer care providers and healthcare systems should be prepared to provide prevention and management strategies and engage in complex medical decision-making for this increasingly common patient population comprised of individuals with cancer and dementia.

Changes in E-Cigarette Perceptions Over Time: A National Youth Tobacco Survey Analysis.

INTRODUCTION: This multiyear, cross-sectional study explores the changes over time in how U.S. middle- and high-school students perceive the harm and addiction risk of E-cigarettes. METHODS: This study analyzed 83,779 participants in the National Youth Tobacco Survey from 2015 to 2019. Associations of survey year with perceived harm and addiction risk of E-cigarettes were assessed using multivariable multinomial logistic regression models, adjusted for sociodemographic characteristics. RESULTS: Smoking decreased over the 5 years (-1.85 percentage points, p=0.07); vaping increased (9.03 percentage points, p<0.01). Perceived harm of both combustible cigarettes and E-cigarettes increased with time. Male, older, and non-White students perceived less harm from smoking or vaping. Perceptions of the addictiveness of E-cigarettes increased over time: 26.31% of students considered E-cigarettes to be more addictive than combustible cigarettes in 2019, compared with 7.26% in 2016. Female and non-White students were more likely to think that E-cigarettes were at least as addictive as combustible cigarettes but also reported less knowledge about them. CONCLUSIONS: The perceptions of both harm and addictiveness of E-cigarettes have increased over time, independent of current use. Perceptions vary on the basis of age, sex, race/ethnicity, and current use. Efforts should be made to further educate adolescents about E-cigarettes and to regulate their sale and advertisement. Efforts to reduce the uptake of combustible cigarettes among adolescents have been successful and should be duplicated for E-cigarettes.
