RESUMO
We aimed to explore the differences in immune checkpoint inhibitor (ICI) immunotherapy utilization for advanced melanoma by examining patient and neighborhood characteristics. We performed a retrospective cohort study using a deidentified, random sample of SEER-Medicare beneficiaries aged ≥65 years with stage III or stage IV melanoma (2011-2017). Our primary outcome was initiation of ICI immunotherapy (ipilimumab, pembrolizumab, nivolumab, or atezolizumab) after stage III or stage IV melanoma diagnosis. We analyzed ICI usage with multivariable logistic regression. After analyzing the entire 2011-2017 cohort, we conducted a secondary analysis in which we separately analyzed the 2011-2014 and 2015-2017 cohorts to assess possible differences over time. We included 3531 beneficiaries, with mean follow-up of 2.1 (SD = 2.0) years. Higher likelihood of ICI usage was associated with male sex (OR = 1.21, 95% confidence interval = 1.04-1.42) and higher density of medical oncologists (OR = 1.02, 95% confidence interval = 1.01-1.04). Lower likelihood of ICI usage was associated with older age group and Charlson comorbidity score (score ≥2; OR = 0.72, 95% confidence interval = 0.60-0.86). These associations were diminished in more recent years (no association with sex, medical oncologist density, Charlson comorbidity score, and association with only the oldest age group in years 2015-2017). We found significant sex- and age-related differences in initiation among SEER-Medicare beneficiaries with stage III or stage IV melanoma, which appear to be improving over time.
RESUMO
Importance: Many patients will develop more than one skin cancer, however most research to date has examined only case status. Objective: Describe the frequency and timing of the treatment of multiple skin cancers in individual patients over time. Design: Longitudinal claims and electronic health record-based cohort study. Setting: Vanderbilt University Medical Center database called the Synthetic Derivative, VA, Medicare, Optum Clinformatics® Data Mart Database, IBM Marketscan. Participants: All patients with a Current Procedural Terminology code for the surgical management of a skin cancer in each of five cohorts. Exposures: None. Main Outcomes and Measures: The number of CPT codes for skin cancer treatment in each individual occurring on the same day as an ICD code for skin cancer over time. Results: Our cohort included 5,508,374 patients and 13,102,123 total skin cancers treated. Conclusions and Relevance: Nearly half of patients treated for skin cancer were treated for more than one skin cancer. Patients who have not developed a second skin cancer by 2 years after the first are unlikely to develop multiple skin cancers within the following 5 years. Better data formatting will allow for improved granularity in identifying individuals at high risk for multiple skin cancers and those unlikely to benefit from continued annual surveillance. Resource planning should take into account not just the number of skin cancer cases, but the individual burden of disease.
RESUMO
BACKGROUND: Immune checkpoint inhibitors (ICIs) have revolutionized the treatment of advanced melanoma, but racial disparities in melanoma outcomes continue. These inequities are not fully explained by individual factors. OBJECTIVE: To investigate the associations of neighborhood factors with the use of ICIs in metastatic melanoma. METHODS: We conducted a retrospective cohort study of commercially insured US adults with metastatic melanoma diagnosed between January 2011 and December 2020. We examined the associations between the county-level percentage of population from racial and ethnic minority groups and the time from metastatic melanoma diagnosis to initiating ICIs using Cox proportional hazards models adjusting for patient characteristics. RESULTS: We identified 4,052 patients with metastatic melanoma, of which 49% used ICIs. We found that the adoption of ICIs in a county declined with increasing minority quintile (quintile 1: 52.4%, quintile 2: 50.4%, quintile 3: 50.1%, quintile 4: 45.8%, and quintile 5: 44.7%). The delay in ICI initiation also went up as the percentage of minorities in a county increased (log-rank test P = 0.03). Compared with the lowest quintile, the adjusted hazard ratio of ICI initiation of the second, third, fourth, and highest minority quintile was 0.94 (95% CI = 0.81-1.08), 0.88 (95% CI = 0.76-1.02), 0.81 (95% CI = 0.68-0.97), and 0.77 (95% CI = 0.66-0.91), respectively. Secondary analysis revealed that the slower initiation was driven by the counties with the highest percentage of Hispanic population (hazard ratio = 0.74; 95% CI = 0.61-0.89) in both Cox models and sensitivity analyses. High-minority counties correlated with metro areas, higher poverty levels, and a greater number of medical oncologists. CONCLUSIONS: We found that patients with metastatic melanoma living in counties with higher proportion of minorities, particularly of Hispanic origin, are more likely to experience delays in ICI treatment. This study provides important population-level data on neighborhood-level disparity in medication use. More research is needed on the underlying provider- and system-level factors that directly contributed to the lower use of cancer medicines in high-minority areas, which can help inform the development of evidence-based medication use strategies that can improve health outcomes and equity.

Introduction: Tumor-related liver failure (TRLF) is the most common cause of death in patients with intrahepatic cholangiocarcinoma (ICC). Though we previously showed that liver radiotherapy (L-RT) for locally advanced ICC is associated with less frequent TRLF and longer overall survival (OS), the role of L-RT for patients with extrahepatic metastatic disease (M1) remains undefined. We sought to compare outcomes for M1 ICC patients treated with and without L-RT. Methods: We reviewed ICC patients that found to have M1 disease at initial diagnosis at a single institution between 2010 and 2021 who received L-RT, matching them with an institutional cohort by propensity score and a National Cancer Database (NCDB) cohort by frequency technique. The median biologically effective dose was 97.5 Gy (interquartile range 80.5-97.9 Gy) for L-RT. Patients treated with other local therapies or supportive care alone were excluded. We analyzed survival with Cox proportional hazard modeling. Results: We identified 61 patients who received L-RT and 220 who received chemotherapy alone. At median follow-up of 11 months after diagnosis, median OS was 9 months (95% confidence interval [CI] 8-11) and 21 months (CI: 17-26) for patients receiving chemotherapy alone and L-RT, respectively. TRLF was the cause of death more often in the patients who received chemotherapy alone compared to those who received L-RT (82% vs. 47%; p = 0.001). On multivariable propensity score-matched analysis, associations with lower risk of death included duration of upfront chemotherapy (hazard ratio [HR] 0.82; p = 0.005) and receipt of L-RT (HR: 0.40; p = 0.002). The median OS from diagnosis for NCDB chemotherapy alone cohort was shorter than that of the institutional L-RT cohort (9 vs. 22 months; p < 0.001). Conclusion: For M1 ICC, L-RT associated with a lower rate of death due to TRLF and longer OS versus those treated with chemotherapy alone. Prospective studies of L-RT in this setting are warranted.
RESUMO
BACKGROUND: Little is known about long-term treatment-related symptoms in older breast cancer survivors. We characterized long-term patient-reported symptoms and examined factors associated with the presence and severity of symptoms, and symptom interference with daily activities. METHODS: Texas Cancer Registry (TCR) Medicare linkage data was used to identify breast cancer patients age 65 and older with local/regional stage disease diagnosed between 2012-2013. Symptom burden was assessed using breast-specific items from the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE™). Demographic and clinical data also were collected. Logistic regression models were used to assess the association between symptom burden and respondent sociodemographic and clinical characteristics. RESULTS: Of 4448 eligible patients, 1594 (response-rate 35.8%) completed questionnaires. Of these, 1245 eligible respondents were included in the analysis based on self-reported data. Median time from diagnosis to survey completion was 68 months (IQR: 62-73). Most frequently reported symptoms were fatigue/lack of energy (76.8%), aching muscles (72.1%) and aching joints (72.5%). Receipt of chemotherapy was associated with higher symptom burden. Patients treated with adjuvant chemotherapy had higher risk of numbness/tingling (OR: 3.16; 95% CI: 2.36-4.24), hair loss (OR: 2.72; 95% CI: 2.05-3.60), and fatigue/lack of energy (OR: 1.80; 95% CI: 1.29-2.52). Similarly, patients who received chemotherapy were more likely to report the majority of symptoms as moderate to severe and as interfering with daily activities. CONCLUSION: Receipt of chemotherapy is associated with significant symptom burden more than 5 years after breast cancer treatment. Long-term chemotherapy impact should be discussed with patients in a shared-decision making process and approaches to symptom management during survivorship care are needed.
RESUMO
BACKGROUND: There is a lack of evidence from nationwide samples on the disparity of initiating immune checkpoint inhibitors (ICIs) after metastatic lung cancer diagnosis. METHODS: We identified metastatic lung cancer patients diagnosed between 2015 and 2020 from a large, nationwide commercial claims database. We analyzed the time from metastatic lung cancer diagnosis to ICI therapy using Cox proportional hazard models. Independent variables included county-level measures (quintiles of percentage of racialized population, quintiles of percentage of population below poverty, urbanity, and density of medical oncologists) and patient characteristics (age, sex, Charlson comorbidity index, Medicare Advantage, and year of diagnosis). All tests were 2-sided. RESULTS: A total of 17â022 patients were included. Counties with a larger proportion of racialized population appeared to be more urban, have a greater percentage of its residents in poverty, and have a higher density of medical oncologists. In Cox analysis, the adjusted hazard ratio of the second, third, fourth, and highest quintile of percentage of racialized population were 0.89 (95% confidence interval [CI] = 0.82 to 0.98), 0.85 (95% CI = 0.78 to 0.93), 0.78 (95% CI = 0.71 to 0.86), and 0.71 (95% CI = 0.62 to 0.81), respectively, compared with counties in the lowest quintile. The slower ICI therapy initiation was driven by counties with the highest percentage of Hispanic population and other non-Black racialized groups. CONCLUSIONS: Commercially insured patients with metastatic lung cancer who lived in counties with greater percentage of racialized population had slower initiation of ICI therapy after lung cancer diagnosis, despite greater density of oncologists in their neighborhood.

Importance: In 2019, the Advisory Committee on Immunization Practices (ACIP) recommended patient-clinician shared decision-making for human papillomavirus (HPV) vaccination in adults aged 27 to 45 years. Less is known about the HPV vaccine administration trends in this age group before and after this recommendation update. Objective: To examine the association between the ACIP recommendation update and the HPV vaccine administration among US adults aged 27 to 45 years. Design, Setting, and Participants: This large commercial claim-based retrospective cohort study used the Optum Clinformatics database for validated claims from January 1, 2007, through December 31, 2020. A total of 22â¯600â¯520 US adults aged 27 to 45 years without previous HPV vaccination claims during the study and enrollment period were included. Main Outcomes and Measures: The first-appearing HPV vaccination claim per individual was defined as a new HPV vaccine administration. Interrupted time-series analyses were conducted to assess the association between the ACIP update and the quarterly vaccine administration rate change. The annual rate trends across race and ethnicity groups and the proportions of vaccination cases by sub-age groups and valent types were also estimated. Vaccine administration trends were assessed by race and ethnicity in this age group because HPV vaccination trends were found to differ by race and ethnicity in the initially eligible population. Results: Among 22â¯600â¯520 final study participants, the majority were men (50.9%) and non-Hispanic White (53.4%), and the mean (SD) age when first observed was 34.6 (5.8) years. In women, the ACIP update was associated with an immediate increase in vaccine administration rate (coefficient ß2, 40.18 per 100â¯000 persons; P = .01) and an increased slope (coefficient ß3, 9.62 per 100â¯000 persons per quarter; P = .03) over time postupdate. The ACIP update was only associated with an immediate increase in vaccine administration in men (coefficient ß2, 27.54; P < .001). The annual rate trends were similar across race and ethnicity groups. Age at vaccine administration shifted over time (eg, women aged 40-45 years comprised only 4.9% of vaccinations in 2017, then 19.0% in 2019, and 22.7% in 2020). The most administered HPV vaccines in 2020 were 9 valent (women, 97.0%; men, 97.7%). Conclusions and Relevance: In this population-based cohort study, there were statistically significant increases in HPV vaccine administration in adults aged 27 to 45 years after the ACIP recommendation update. Patient-clinician shared decision-making may have been the main associated factor for this increase. Further research is warranted to explore the decision-making process in receiving HPV vaccination and to develop effective decision aids to maximize the cancer prevention benefit in this age group.

PURPOSE: The rapidly rising costs of targeted oral anticancer medicines (TOAMs) raise concerns over their affordability. Our goal was to examine recent trends in the uptake of TOAMs among cancer patients with Medicare Part D, the share of TOAM users who reached catastrophic coverage, and the annual spending on TOAMs in the catastrophic phase. METHODS: Using the 5% SEER-Medicare, we included patients age 65 years and older who had one primary cancer diagnosis between 2011 and 2016. We included person-years where patients were enrolled in a Part D plan for the entire year, did not receive the low-income subsidy at any time of the year, and received anticancer systemic therapies. We estimated the trends in the share of patients who used TOAMs, the percentage of TOAM users reaching catastrophic coverage, and the total and patient out-of-pocket spending on TOAMs in the catastrophic phase in a year. RESULTS: From 2011 to 2016, the uptake of TOAMs among our study population increased from 3.6% to 8.9%. The percentage of non-low-income subsidy TOAM users who reached catastrophic coverage increased from 54.6% to 60.3%. Among those who reached the catastrophic phase, mean total gross spending on TOAMs in the catastrophic phase increased from $16,074 (USD) to $64,233 (USD) and mean patient out-of-pocket spending from $596 (USD) to $2,549 (USD). The mean 30-day total spending increased from $4,011 (USD) to $8,857 (USD), and the mean 30-day out-of-pocket spending from $154 (USD) to $328 (USD). CONCLUSION: The high and growing burden from TOAMs highlighted the need for reining in drug prices and capping out-of-pocket spending.

Purpose: In patients treated with chemoradiation for esophageal cancer (EC), randomized trial data demonstrate that proton beam therapy (PBT) reduces toxicities and postoperative complications (POCs) compared with intensity-modulated radiation therapy (IMRT). However, whether radiation therapy modality affects postoperative health care resource utilization remains unknown. Materials and Methods: We examined 287 patients with EC who received chemoradiation (prescribed 50.4 Gy/GyE) followed by esophagectomy, including a real-world observational cohort of 237 consecutive patients treated from 2007 to 2013 with PBT (n = 81) versus IMRT (n = 156); and an independent, contemporary comparison cohort of 50 patients from a randomized trial treated from 2012 to 2019 with PBT (n = 21) versus IMRT (n = 29). Postoperative complications were abstracted from medical records. Health care charges were obtained from institutional claims and adjusted for inflation (2021 dollars). Charge differences (Δ = $PBT - $IMRT) were compared by treatment using adjusted generalized linear models with the gamma distribution. Results: Baseline PBT versus IMRT characteristics were not significantly different. In the observational cohort, during the neoadjuvant chemoradiation phase, health care charges were higher for PBT versus IMRT (Δ = +$71,959; 95% confidence interval [CI], $62,274-$82,138; P < .001). There was no difference in surgical charges (Δ = -$2234; 95% CI, -$6003 to $1695; P = .26). However, during postoperative hospitalization following esophagectomy, health care charges were lower for PBT versus IMRT (Δ = -$25,115; 95% CI, -$37,625 to -$9776; P = .003). In the comparison cohort, findings were analogous: Charges were higher for PBT versus IMRT during chemoradiation (Δ = +$61,818; 95% CI, $49,435-$75,069; P < .001), not different for surgery (Δ = -$4784; 95% CI, -$6439 to $3487; P = .25), and lower for PBT postoperatively (Δ = -$27,048; 95% CI, -$41,974 to -$5300; P = .02). Lower postoperative charges for PBT were especially seen among patients with any POCs in the contemporary comparison (Δ = -$176,448; 95% CI, -$209,782 to -$78,813; P = .02). Conclusion: Higher up-front chemoradiation resource utilization for PBT in patients with EC was partially offset postoperatively, moderated by reduction in POC risks. Results extend existing clinical evidence of toxicity reduction with PBT.
RESUMO
BACKGROUND: Brainstem toxicity after radiation therapy (RT) is a devastating complication and a particular concern with proton radiation (PBT). We investigated the incidence and clinical correlates of brainstem injury in pediatric brain tumors treated with PBT. METHODS: All patients <21 years with brain tumors treated with PBT at our institution from 2007-2019, with a brainstem Dmean >30 Gy and/or Dmax >50.4 Gy were included. Symptomatic brainstem injury (SBI) was defined as any new or progressive cranial neuropathy, ataxia, and/or motor weakness with corresponding radiographic abnormality within brainstem. RESULTS: A total of 595 patients were reviewed and 468 (medulloblastoma = 200, gliomas = 114, ependymoma = 87, ATRT = 43) met our inclusion criteria. Median age at RT was 6.3 years and median prescribed RT dose was 54Gy [RBE]. Fifteen patients (3.2%) developed SBI, at a median of 4 months after RT. Grades 2, 3, 4, and 5 brainstem injuries were seen in 7, 5, 1, and 2 patients respectively. Asymptomatic radiographic changes were seen in 51 patients (10.9%). SBI was significantly higher in patients with age ≤3 years, female gender, ATRT histology, patients receiving high-dose chemotherapy with stem cell rescue, and those not receiving craniospinal irradiation. Patients with SBI had a significantly higher V50-52. In 2014, our institution started using strict brainstem dose constraints (Dmax ≤57 Gy, Dmean ≤52.4 Gy, and V54≤10%). There was a trend towards decrease in SBI from 4.4% (2007-2013) to 1.5% (2014-2019) (P = .089) without affecting survival. CONCLUSION: Our results suggest a low risk of SBI after PBT for pediatric brain tumors, comparable to photon therapy. A lower risk was seen after adopting strict brainstem dose constraints.

PURPOSE: Non-white cancer patients receive more aggressive care at the end-of-life (EOL). This may indicate low quality EOL care if discordant with patient preferences. We investigated preferred potential place of death and preferences regarding use of mechanical ventilation in a cohort of Texas cancer patients. METHODS: A population-based convenience sample of recently diagnosed cancer patients from the Texas Cancer Registry was surveyed using a multi-scale inventory between March 2018 and June 2020. Item responses to questions about preferences regarding location of death and mechanical ventilation were the outcome measures of this investigation. Inverse probability weighting analysis was used to construct multivariable logistic regression examining the associations of covariates. RESULTS: Of the 1460 respondents, a majority (82%) preferred to die at home compared to 8% who preferred dying at the hospital. In total, 25% of respondents expressed a preference for undergoing mechanical ventilation at the EOL. Adjusted analysis showed increased preference among Black (OR = 1.81; 95% CI: 1.19-2.73) and other non-white, non-Hispanic race individuals (OR = 3.53; 95% CI: 1.99-6.27) for dying at a hospital. Males, married individuals, those of higher education and poor self-reported health showed significantly higher preference for dying at home. Non-white respondents of all races were more likely to prefer mechanical ventilation at the EOL as were individuals who lived with another person at home. CONCLUSION: Non-white cancer patients were more likely to express preferences coinciding with aggressive EOL care including dying at the hospital and utilizing mechanical ventilation. These findings were independent of other sociodemographic characteristics, including decisional self-efficacy.

BACKGROUND: The authors analyzed the incidence and types of second malignant neoplasms (SMNs) in patients treated for medulloblastoma. METHODS: The authors compared the incidence of SMNs after radiotherapy (RT) for medulloblastoma in patients treated in 1973-2014 with the incidence in the general population with the multiple primary-standardized incidence ratio function of Surveillance, Epidemiology, and End Results 9. Observed-to-expected incidence (O/E) ratios and 95% confidence intervals (CIs) were reported for the entire cohort and by disease site according to age at diagnosis, treatment era, and receipt of chemotherapy. P values < .05 were considered statistically significant. RESULTS: Of the 1294 patients with medulloblastoma who received RT, 68 developed 75 SMNs. The O/E ratio for SMNs among all patients was 4.49 (95% CI, 3.53-5.62; P < .05). The site at highest risk was the central nervous system (CNS; O/E, 40.62; 95% CI, 25.46-61.51), which was followed by the endocrine system (O/E, 15.95; 95% CI, 9.12-25.91), bone (O/E, 14.45; 95% CI, 1.75-52.21), soft tissues (O/E, 9.01; 95% CI, 1.09-32.56), the digestive system (O/E, 5.03; 95% CI, 2.51-9.00), and the lymphatic/hematopoietic system (O/E, 3.37; 95% CI, 1.35-6.94). The O/E ratio was higher for patients given chemotherapy and RT (O/E, 5.52; 95% CI, 3.75-7.83) than for those given RT only (O/E, 3.96; 95% CI, 2.88-5.32). CONCLUSIONS: Patients with medulloblastoma are at elevated risk for SMNs in comparison with the general population. Variations in O/E for SMNs by organ systems were found for treatment modality, age at diagnosis, and time of diagnosis. The most common site, the CNS, was involved more often in younger patients and those given chemotherapy with RT.

INTRODUCTION: Levels of medical mistrust have historically been higher among racial/ethnic minority patients compared with whites, largely owing to societal and health system inequities and history of discrimination or experimentation. However, recently trust in physicians has declined in the United States in general. We investigated trust in physicians among a large cohort of cancer patients residing in Texas. METHODS: A sample of recently diagnosed cancer patients in Texas were identified from the Texas Cancer Registry with 1344 patients returning surveys between March 2017 and March 2020. The multiscale inventory was mailed to each individual and included the Trust in the Medical Profession Scale which assesses levels of agreement with 11 trust-related statements. Multivariable linear regression models were constructed to assess the adjusted relationship between trust in the medical profession aggregate score and sociodemographic and clinical factors. RESULTS: A total of 1250 surveys were evaluable for trust in the medical profession. The mean aggregate trust score for all patients was 37.3 (95% confidence interval: 36.8-37.7). Unadjusted trust scores were higher for Hispanic (40.5) and black (38.2) respondents compared with white (36.4) (P<0.001). Multivariable analyses showed white, younger, more-educated, or those with lower levels of self-reported health estimated toward lower adjusted scores for trust in the medical profession. CONCLUSIONS: We observed relatively higher levels of medical mistrust among white, younger, more-educated individuals with cancer or those with poorer health. While the relatively higher trust among minority individuals is encouraging, these findings raise the possibility that recent societal trends toward mistrust in science may have implications for cancer care.

CONTEXT: Minority patients receive more aggressive and potentially suboptimal care at the end of life (EOL). We investigated preferences about pharmacologic interventions at the EOL and their potential variation by sociodemographic factors among recently diagnosed cancer patients. METHODS: A population-based cross-sectional survey of cancer patients identified through the Texas Cancer registry was conducted using a multi-scale inventory between March 2018 and June 2020. Item responses to questions about potential pharmacologic interventions at the EOL were the focus of this investigation. Inverse probability weighted multivariate analysis examined associations of sociodemographic characteristics, health literacy, and trust in medical professionals with pharmacologic preferences. RESULTS: Of the 1480 included responses, 13.3% stated they would take a medication that may prolong life at the cost of feeling worse. Adjusted analyses showed Black or Hispanic race/ethnicity, living with another person, and having a higher trust score were more likely to express this preference. In contrast, 41-65 years (vs. 21-40 years), living in a rural area, and adequate or unknown health literacy were less likely to express this preference. Overall 16% of respondents were opposed to potentially life shortening palliative drugs. In adjusted analysis Black or Hispanic respondents were more likely to be opposed to potentially life shortening drugs although age 65-79 and ≥college education were associated with a decreased likelihood of opposition to this item. CONCLUSION: Black and Hispanic cancer patients were more likely to express preferences toward more aggressive EOL pharmacologic care. These findings were independent of other sociodemographic characteristics, health literacy and trust in the medical profession.

PURPOSE: We describe large-scale demographic, initial treatment, and outcomes data for pediatric grade II gliomas included in the National Cancer Database from 2004 to 2014. METHODS: Our cohort included cases less than 21 years of age with pathology-confirmed disease. Logistic regressions were used to evaluate the use of chemotherapy (CT) and radiation therapy (RT). Overall survival (OS) rates were determined using Kaplan-Meier estimates and the log-rank test. RESULTS: We identified 803 cases with astrocytoma (56.2%), oligodendroglioma (26.0%), and mixed glioma/glioma NOS (17.8%) histologies. Most cases underwent surgical resection (n = 661). Whereas cases 16 to 21 years of age were more likely than cases 0 to 5 years to receive RT (OR = 7.38, 95% CI 3.58-15.21, p < 0.001), they were less likely to receive CT (OR = 0.34, 95% CI 0.22-0.52, p < 0.001). The 5-year OS rates for all cases, cases that underwent surgical resection, and cases managed with biopsy were 87.5%, 92.7%, and 63.6%, respectively. CONCLUSION: In one of the largest series of pediatric grade II gliomas, astrocytoma was the most common histology. Patterns of care and OS outcomes were similar to grade I gliomas, with surgical resection being the most common initial treatment and associated with a favorable rate of OS. Younger patients were more likely to receive post-operative CT and the use of RT increased with age.

Background. Screening with low-dose computed tomography scans can reduce lung cancer deaths but uptake remains low. This study examines psychosocial factors associated with obtaining lung cancer screening (LCS) among individuals. Methods. This is a secondary analysis of a randomized clinical trial conducted with 13 state quitlines' clients. Participants who met age and smoking history criteria were enrolled and followed-up for 6 months. Only participants randomized to the intervention group (a patient decision aid) were included in this analysis. A logistic regression was performed to identify determinants of obtaining LCS 6 months after the intervention. Results. There were 204 participants included in this study. Regarding individual attitudes, high and moderate levels of concern about overdiagnosis were associated with a decreased likelihood of obtaining LCS compared with lower levels of concern (high levels of concern, odds ratio [OR] 0.17, 95% confidence interval [CI] 0.04-0.65; moderate levels of concern, OR 0.15, 95% CI 0.05-0.53). In contrast, higher levels of anticipated regret about not obtaining LCS and later being diagnosed with lung cancer were associated with an increased likelihood of being screened compared with lower levels of anticipated regret (OR 5.59, 95% CI 1.72-18.10). Other potential harms related to LCS were not significant. Limitations. Follow-up may not have been long enough for all individuals who wished to be screened to complete the scan. Additionally, participants may have been more health motivated due to recruitment via tobacco quitlines. Conclusions. Anticipated regret about not obtaining screening is associated with screening behavior, whereas concern about overdiagnosis is associated with decreased likelihood of LCS. Implications. Decision support research may benefit from further examining anticipated regret in screening decisions. Additional training and information may be helpful to address concerns regarding overdiagnosis.
RESUMO
In the treatment of localized Ewing sarcoma (EWS), delays in local therapy are known to adversely impact overall survival (OS). However, the role of treatment center volume in EWS outcomes, and the interaction between center volume and local therapy timing with definitive radiotherapy, remains unknown. Using the National Cancer Database, we demonstrate that treatment at the lowest EWS volume centers is associated with reduced OS, explained partly by higher rates of delayed local therapy. Treatment at the highest volume centers results in improved OS, but appears independent of radiotherapy timing. Future efforts to improve care for EWS patients across treatment centers are imperative.

BACKGROUND: The role of adjuvant radiation after gross total resection (GTR) for grade II meningioma is evolving, prompting further evaluation in NRG-BN003, a phase 3 national trial. Furthermore, the relationship between facility volume and outcomes in patients with grade II meningioma after GTR has not been examined at a national level. We aim to assess overall survival (OS) of patients with grade II meningioma after GTR by surgical case volume and OS by receipt of adjuvant radiation. METHODS: We used the National Cancer Database to identity 2823 patients diagnosed with grade II meningioma who underwent GTR. Propensity score matching was applied to balance covariates in patients with grade II meningioma after GTR stratified by adjuvant radiation status. Multivariable logistic regression was used to assess factors associated with radiation receipt. Kaplan-Meier and log-rank tests were used to assess OS by facility volume. RESULTS: As facility volume increased, OS increased, with a 5-year OS of 72.8% for facilities with GTR grade II meningioma volumes of ≤8 cases per decade and 87.5% for >8 cases per decade (P < 0.0001). There was no difference in 5-year OS between GTR alone and GTR with adjuvant radiation (84.8% vs. 86.4%; P = 0.151). Covariates significantly associated with radiation receipt included facility location, facility volume, distance, and tumor size. CONCLUSIONS: Treatment at higher surgical case volume facilities is associated with improved OS for GTR grade II meningioma. These facilities also have more patients receiving adjuvant radiation. However, we observed no difference in OS between adjuvant radiation and surgery alone.

BACKGROUND: As treatment modalities for medulloblastoma have developed and overall survival (OS) has improved, there are relatively limited data on the impact of long-term effects such as risk of second primary tumors (SPT). To address the knowledge gap, we analyzed factors associated with the risk of SPT and OS by treatment modality for medulloblastoma. METHODS: We queried the Surveillance, Epidemiology, and End Results (SEER)-18 database for patients diagnosed with medulloblastoma in 1973-2014. Patients were then grouped by age, gender, race, geographic region, histology, adjuvant treatment (no radiation [RT] and no chemotherapy [CT], RT and CT, RT alone, or CT alone), era of diagnosis (1973-1994 or 1995-2014), and survival time. Cumulative incidence, factors associated with SPT and OS were analyzed. RESULTS: Of 2271 patients, 146 developed SPT, of which 42 were benign. The incidence of SPT was 3.1% and 4.9% at 10 and 15 years, respectively. The incidence of SPT was 3.1% with RT + CT versus 3.7% with RT alone at 10 years. The most common site for an SPT was the central nervous system. Female gender (P = 0.01) and longer OS of ≥21 years (P < 0.01) were associated with higher risk of SPT. RT + CT led to better OS than RT only (66.1% and 61.4% vs 55.6% and 49.7% at 10 and 15 years) (P < 0.01). CONCLUSIONS: Medulloblastoma patients have a relatively low risk of SPT at 10 years with treatment. Use of RT + CT led to better OS with no statistical difference in SPT compared with the RT alone.

PURPOSE: Although rates of hospice use have increased over time, insurance plan- and racial/ethnic-based disparities in rates have been reported in the USA. We hypothesized that increased rates of hospice use would reduce or eliminate insurance plan-based disparities and that racial/ethnic disparities would be eliminated in managed care (MC) insurance plans. METHODS: We studied the use of hospice care in the final 30 days of life among 40,184 elderly Texas Medicare beneficiaries who died from primary breast, colorectal, lung, pancreas, or prostate cancer between January 1, 2007 and December 31, 2013, using statewide Medicare claims linked to cancer registry data. Rates of hospice use were computed by race/ethnicity and insurance plan (MC or fee-for-service (FFS)). We used logistic regression to account for the impact of confounding factors. RESULTS: Rates of hospice use increased significantly over time, from 68.9% in 2007 to 76.1% in 2013. By 2013, differences in hospice use rates between MC and FFS plans had been reduced from 10% to < 5%. However, after accounting for insurance plan and confounding factors, racial/ethnic minority beneficiaries' hospice use was significantly lower than non-Hispanic white beneficiaries' (p < 0.0001). This disparity was observed among both FFS and MC beneficiaries. CONCLUSIONS: Hospice use in the final 30 days of life has increased among elderly cancer patients in Texas, virtually eliminating the difference between FFS and MC insurance plans. Despite these positive trends, racial/ethnic-based disparities persist. These disparities are not explained by confounding factors. Future research should address social and behavioral influences on end-of-life decisions.
