RESUMEN

BACKGROUND: Cancer survivors have increased risk of endocrine complications, but there is a lack of information on the occurrence of specific endocrinopathies at the population-level. METHODS: We used data from the California Cancer Registry (2006-2018) linked to statewide hospitalisation, emergency department, and ambulatory surgery databases. We estimated the cumulative incidence of and factors associated with endocrinopathies among adolescents and young adults (AYA, 15-39 years) who survived ≥2 years after diagnosis. RESULTS: Among 59,343 AYAs, 10-year cumulative incidence was highest for diabetes (4.7%), hypothyroidism (4.6%), other thyroid (2.2%) and parathyroid disorders (1.6%). Hypothyroidism was most common in Hodgkin lymphoma, leukaemia, breast, and cervical cancer survivors, while diabetes was highest among survivors of leukaemias, non-Hodgkin lymphoma, colorectal, cervical, and breast cancer. In multivariable models, factors associated with increased hazard of endocrinopathies were treatment, advanced stage, public insurance, residence in low/middle socioeconomic neighbourhoods, older age, and non-Hispanic Black or Hispanic race/ethnicity. Haematopoietic cell transplant was associated with most endocrinopathies, while chemotherapy was associated with a higher hazard of ovarian dysfunction and hypothyroidism. CONCLUSIONS: We observed a high burden of endocrinopathies among AYA cancer survivors, which varied by treatment and social factors. Evidence-based survivorship guidelines are needed for surveillance of these diseases.

RESUMEN

BACKGROUND: Sociodemographic and clinical factors associated with diagnostic delays in pediatric, adolescent, and young adult cancers are poorly understood. METHODS: Using the Optum Labs Data Warehouse's de-identified claims data for commercial health plan enrollees, we identified children (0-14 years) and adolescents/young adults (AYAs) (15-39 years) diagnosed with one of 10 common cancers from 2001 to 2017, who were continuously enrolled for 6 months preceding diagnosis. Time to diagnosis was calculated as days between first medical encounter with possible cancer symptoms and cancer diagnosis date. Median times from first symptom to diagnosis were compared using Wilcoxon rank sum test. Multivariable unconditional logistic regression identified sociodemographic factors associated with longer time (>3 months) to cancer diagnosis (from symptom onset). RESULTS: Of 47,296 patients, 87% presented prior to diagnosis with symptoms. Patients with central nervous system (CNS) tumors were most likely to present with symptoms (93%), whereas patients with cervical cancer were least likely (70%). Symptoms varied by malignancy. Of patients with symptoms, thyroid (105 days [range: 50-154]) and cervical (104 days [range: 41-151]) cancer had the longest median time to diagnosis. Females and patients at either end of the age spectrum were more likely to experience diagnosis delays of more than 3 months. CONCLUSION: In a commercially insured population, time to diagnosis varies by cancer type, age, and sex. Further work is needed to understand the patient, provider, and health system-level factors contributing to time from symptom onset to diagnosis, specifically in the very young children and the young adult patient population going forward.

RESUMEN

PURPOSE: Breast cancer (BC) is the most common secondary cancer and has poorer survival than primary BC (pBC) after any prior malignancy. For BC survivors, developing a contralateral secondary BC (CSBC) is the most frequent second-cancer event and is currently treated similarly to pBC. Identifying survival differences between pBC and CSBC could influence future counseling and treatments for patients with CSBC. METHODS: Women (≥15 years) diagnosed with pBC from 1991 to 2015 in the California Cancer Registry (n = 377,176) were compared with those with CSBC (n = 15,586) by age group (15-39 years, n = 406; 40-64 years, n = 6814; ≥ 65 years, n = 8366). Multivariable logistic regression models assessed factors associated with CSBC. Multivariable Cox proportional hazards regression models assessed BC-specific survival (BCSS), while accounting for the competing risk of death. RESULTS: Across all ages, CSBC patients were more likely to have smaller tumors (T2 vs. T1a; 15-39 yeras: OR 0.25, CI 0.16-0.38; 40-64 years: OR 0.41, CI 0.37-0.45; ≥ 65 years: OR 0.46, CI 0.42-0.51) and lymph node-negative disease (positive vs. negative; 15-39 years: OR 0.86, CI 0.69-1.08; 40-64 years: OR 0.88, CI 0.83-0.93; ≥ 65 years: OR 0.89, CI 0.84-0.94). Additionally, CSBC was associated with worse survival compared with pBC across all ages (15-39 years: HR 2.73, CI 2.30-3.25; 40-64 years: HR 2.13, CI 2.01-2.26; ≥ 65 years: HR 1.52, CI 1.43-1.61). CONCLUSION: BCSS is worse among all women diagnosed with CSBC compared with pBC, with the strongest impact seen in adolescent and young adult women. Worse survival after CSBC, despite associations with smaller tumors and lymph node negativity, suggests that CSBC may need eventual treatment reconsideration.

RESUMEN

Adverse pregnancy outcomes occur frequently in women with sickle cell disease (SCD) across the globe. In the United States, Black women experience disproportionately worse maternal health outcomes than all other racial groups. To better understand how social determinants of health impact SCD maternal morbidity, we used California's Department of Health Care Access and Information data (1991-2019) to estimate the cumulative incidence of pregnancy outcomes in Black women with and without SCD-adjusted for age, insurance status, and Distressed Community Index (DCI) scores. Black pregnant women with SCD were more likely to deliver at a younger age, use government insurance, and live in at-risk or distressed neighborhoods, compared to those without SCD. They also experienced higher stillbirths (26.8, 95% confidence interval [CI]: 17.5-36.1 vs. 12.4 [CI: 12.1-12.7], per 1000 births) and inpatient maternal mortality (344.5 [CI: 337.6-682.2] vs. 6.1 [CI: 2.3-8.4], per 100 000 live births). Multivariate logistic regression models showed Black pregnant women with SCD had significantly higher odds ratios (OR) for sepsis (OR 14.89, CI: 10.81, 20.52), venous thromboembolism (OR 13.60, CI: 9.16, 20.20), and postpartum hemorrhage (OR 2.25, CI 1.79-2.82), with peak onset in the second trimester, third trimester, and six weeks postpartum, respectively. Despite adjusting for sociodemographic factors, Black women with SCD still experienced significantly worse pregnancy outcomes than those without SCD. We need additional studies to determine if early introduction to reproductive health education, continuation of SCD-modifying therapies during pregnancy, and increasing access to multidisciplinary perinatal care can reduce morbidity in pregnant women with SCD.

RESUMEN

Adolescents and young adults (AYAs, 15-39 years) are the largest uninsured population in the Unites States, increasing the likelihood of late-stage cancer diagnosis and poor survival. We evaluated the associations between the Affordable Care Act (ACA), insurance coverage, stage at diagnosis and survival among AYAs with lymphoma. We used data from the California Cancer Registry linked to Medicaid enrollment files on AYAs diagnosed with a primary non-Hodgkin (NHL; n = 5959) or Hodgkin (n = 5378) lymphoma pre-ACA and in the early and full ACA eras. Health insurance was categorized as continuous Medicaid, discontinuous Medicaid, Medicaid enrollment at diagnosis/uninsurance, other public and private. We used multivariable regression models for statistical analyses. The proportion of AYAs uninsured/Medicaid enrolled at diagnosis decreased from 13.4% pre-ACA to 9.7% with full ACA implementation, while continuous Medicaid increased from 9.3% to 29.6% during this time (P < .001). After full ACA, AYAs with NHL were less likely to be diagnosed with Stage IV disease (adjusted odds ratio [aOR] = 0.84, 95% confidence interval [CI] = 0.73-0.97). AYAs with lymphoma were more likely to receive care at National Cancer Institute-Designated Cancer Centers (aOR = 1.42, 95% CI = 1.28-1.57) and had lower likelihood of death (adjusted hazard ratio = 0.54, 95% CI = 0.46-0.63) after full ACA. However, AYAs from the lowest socioeconomic neighborhoods, racial/ethnic minority groups and those with Medicaid continued to experience worse survival. In summary, AYAs with lymphomas experienced increased access to healthcare and better clinical outcomes following Medicaid expansion under the ACA. Yet, socioeconomic and racial/ethnic disparities remain, calling for additional efforts to decrease health inequities among underserved AYAs with lymphoma.

RESUMEN

BACKGROUND: Adolescent and young adult (AYA) cancer survivors experience psychological distress often because of cancer and its treatment. However, no prior studies have evaluated the additional medical expenditures and health care utilization associated with psychological distress in AYA cancer survivors. METHODS: AYA cancer survivors and a comparison matched group of adults with no history of cancer were identified from 2011-2016 Medical Expenditure Panel Survey data. Medical expenditures and health care utilization were evaluated with multivariable regression models. RESULTS: AYA cancer survivors were more likely to have psychological distress (11.5% of 1757) than adults with no history of cancer (5.8% of 5227). The prevalence of psychological distress was found to be high many years after the diagnosis, with 11.2% reporting distress ≥20 years after their cancer diagnosis. AYA cancer survivors with psychological distress were more likely to smoke and have chronic conditions and were less likely to exercise regularly in comparison with AYAs with no history of psychological distress. AYA cancer survivors with psychological distress had additional annual medical expenses ($4415; 95% CI, $993-$9690), office visits (2.80; 95% CI, 0.23-6.15), and use of prescription medications/medication renewals (11.58; 95% CI, 5.70-19.47) in comparison with AYA cancer survivors without psychological distress. Additional annual medical expenses of psychological distress were $2600 higher in AYA cancer survivors than adults without a history of cancer ($1802; 95% CI, $440-$3791). CONCLUSIONS: These results highlight the substantial economic burden associated with psychological distress in AYA cancer survivors. This research could inform survivorship care plans and interventions addressing the psychological needs of AYA cancer survivors.

RESUMEN

BACKGROUND: Traditionally, conventional induction chemotherapy has been the primary frontline treatment for acute myeloid leukemia (AML); however, older adults are often poor chemotherapy candidates. Recently, several nonconventional frontline AML regimens, including hypomethylating agents, the BCL-2 inhibitor venetoclax, and targeted therapies, have emerged, and they may offer new options for older adults. This study was aimed at describing treatment patterns and outcomes of older adult AML in a modern population-based cohort. METHODS: This study evaluated patients aged ≥60 years with a first primary diagnosis of AML (2014-2017) in the California Cancer Registry linked to inpatient hospitalizations. Multivariable regression examined factors associated with the frontline treatment regimen and survival. RESULTS: In all, 3068 patients were included; 36% received frontline therapy with a conventional chemotherapy backbone, 42% received nonconventional therapy, and 22% received no treatment. The use of nonconventional therapy increased over time from 38% of patients in 2014 to 47% in 2017 (P < .001). In multivariable analyses, receipt of treatment was associated with an age younger than 80 years, fewer than 2 comorbidities, and care at a National Cancer Institute-designated cancer center (NCI-CC). Compared with conventional chemotherapy, nonconventional therapy was associated with Black race/ethnicity, public health insurance, fewer hospital admissions, and fewer inpatient days. Receiving frontline therapy at an NCI-CC was independently associated with superior overall survival. CONCLUSIONS: Using a population-based approach, this study has demonstrated that patterns of care for frontline AML treatment in older adults are changing, with increasing use of nonconventional therapies. A significant proportion of older adults remain untreated. At the population level, there remain opportunities to increase therapy access for older adults with AML.

RESUMEN

BACKGROUND: Despite efforts to increase participation of adolescents and young adults (AYAs; 15-39 years) in cancer clinical trials (CTs), enrollment remains very low. Even when provided access to CTs, AYAs are less likely to participate than children and older adults. A better understanding of oncologist- and AYA survivor-reported barriers, facilitators, and potential areas for CT enrollment improvement is needed. PROCEDURES: From December 2019 to August 2020, we conducted 43 semi-structured interviews with oncologists (n = 17) and AYA cancer survivors (n = 26) who were offered and/or participated in CTs at cancer centers in California and Utah. Thematic analyses were used to interpret the findings. RESULTS: Oncologists identified a lack of available CTs, strict eligibility criteria, lack of awareness of open CTs, and poor communication between pediatric and adult oncologists as major barriers to enrollment. AYA cancer survivors identified financial and psychosocial barriers, and a poor understanding of what a CT means and its potential benefits as barriers to enrollment. Areas for improvement identified by oncologists and AYAs include educational, financial, and psychosocial support to AYAs. Oncologists also emphasized the need to increase CT availability, improve awareness of open CTs, and better communication between both pediatric and adult oncologists and oncologists and AYAs. CONCLUSIONS: For AYAs with cancer, a lack of CT eligibility and physician awareness of open CTs likely factor into their lower CT enrollment. Potential strategies to improve AYA enrollment in CTs require comprehensive collaboration between pediatric and adult institutions, as well as educational, psychosocial, and financial support to AYAs.

RESUMEN

Stressful environments have been associated with earlier menarche. We hypothesized that anxiety, and possibly other internalizing symptoms, are also associated with earlier puberty in girls. The Lessons in Epidemiology and Genetics of Adult Cancer From Youth (LEGACY) Girls Study (2011-2016) included 1,040 girls aged 6-13 years at recruitment whose growth and development were assessed every 6 months. Prepubertal maternal reports of daughter's internalizing symptoms were available for breast onset (n = 447), pubic hair onset (n = 456), and menarche (n = 681). Using Cox proportional hazard regression, we estimated prospective hazard ratios and 95% confidence intervals for the relationship between 1 standard deviation of the percentiles of prepubertal anxiety, depression, and somatization symptoms and the timing of each pubertal outcome. Multivariable models included age, race/ethnicity, study center, maternal education, body mass index percentile, and family history of breast cancer. Additional models included maternal self-reported anxiety. A 1-standard deviation increase in maternally reported anxiety in girls at baseline was associated with earlier subsequent onset of breast (hazard ratio (HR) = 1.22, 95% confidence interval (CI): 1.09, 1.36) and pubic hair (HR = 1.15, 95% CI: 1.01, 1.30) development, but not menarche (HR = 0.94, 95% CI: 0.83, 1.07). The association of anxiety with earlier breast development persisted after adjustment for maternal anxiety. Increased anxiety in young girls may indicate risk for earlier pubertal onset.

RESUMEN

BACKGROUND: Hodgkin lymphoma (HL) is a treatable tumor affecting children, adolescents and young adults (AYAs; 15-39 years old). Population-based studies report worse survival for non-White children and AYAs but have limited data on individual therapeutic exposures. This study examined overall and HL-specific survival in a population-based cohort of patients while adjusting for sociodemographic factors and treatment. METHODS: Data for 4807 patients younger than 40 years with HL (2007-2017) were obtained from the California Cancer Registry. Individual treatment information was extracted from text fields; chemotherapy regimens were defined by standard approaches for pediatric and adult HL. Multivariable Cox models examined the influence of patient and treatment factors on survival. RESULTS: At a median follow-up of 4.4 years, 95% of the patients were alive. Chemotherapy differed by age, with 70% of 22- to 39-year-olds and 41% of <22-year-olds receiving doxorubicin, bleomycin, vinblastine, and dacarbazine (P < .001). In multivariable models, older patients (22-39 vs < 21 y; hazard ratio [HR], 1.53; 95% confidence interval [CI], 1.11-2.10), Black (vs White patients); HR, 1.90; 95% CI, 1.25-2.88), and Hispanic patients (HR, 1.45; 95% CI, 1.06-1.99) experienced worse survival; among those < 21 y, Black race was associated with a 3.3-fold increased risk of death (HR, 3.26; 95% CI, 1.43-7.42). CONCLUSIONS: In children and AYAs with HL, older age and non-White race/ethnicity predicted worse survival after adjustments for treatment data. Further work is needed to identify the biological and nonbiological factors driving disparities in these at-risk populations.

RESUMEN

PURPOSE: Through screening and HPV vaccination, cervical cancer can mostly be prevented or detected very early, before symptoms develop. However, cervical cancer persists, and many women are diagnosed at advanced stages. Little is known about the degree to which U.S. women may begin their diagnostic workup for cervical cancer in Emergency Departments (ED). We sought to quantify the proportion of women presenting symptomatically in the ED prior to their diagnosis with cervical cancer and to describe their characteristics and outcomes. METHODS: We identified women diagnosed from 2006 to 2017 with cervical cancer in the California Cancer Registry. We linked this cohort to statewide ED discharge records to determine ED use and symptoms present at the encounter. Multivariable logistic regression models examined associations with ED use and multivariable Cox proportional hazards regression models examined associations with survival. RESULTS: Of the more than 16,000 women with cervical cancer in the study cohort, 28% presented symptomatically in the ED prior to diagnosis. Those presenting symptomatically were more likely to have public (odds ratio [OR] 1.16; 95% confidence interval [CI] 1.06-1.27) or no insurance (OR 4.81; CI 4.06-5.71) (vs. private), low socioeconomic status (SES) (OR 1.76; CI 1.52-2.04), late-stage disease (OR 5.29; CI 4.70-5.96), and had a 37% increased risk of death (CI 1.28-1.46). CONCLUSION: Nearly a third of women with cervical cancer presented symptomatically, outside of a primary care setting, suggesting that many women, especially those with low SES, may not be benefiting from screening or healthcare following abnormal results.

RESUMEN

PURPOSE: To assess changes in health insurance coverage for young cancer patients pre- and post- the Affordable Care Act-Dependent Care Expansion (ACA-DCE) implementation in California. Further, we examined differences in insurance coverage by socioeconomic and race/ethnicity. METHODS: Data were obtained from the California Cancer Registry and Medicaid enrollment files, from 2005 to 2014. We conducted difference-in-difference analyses among 7042 cancer patients aged 22-25 years ("intervention group") and 25,269 aged 26-34 years ("control group"). We also examined the independent and combined effects of race/ethnicity and neighborhood socioeconomic status (nSES) on insurance coverage. RESULTS: After the ACA-DCE implementation, we observed a 52.7% reduction in the proportion of uninsured and a 35.7% increase in the proportion of privately insured patients. There was also a 17.3% reduction in Medicaid at cancer diagnosis and a 27.5% reduction in discontinuous Medicaid enrollment. However, these benefits were limited to patients of non-Hispanic White, Hispanic and Asian/Pacific Islander race/ethnicity living in higher nSES, with no differences in insurance enrollment among young adults who lived in low nSES or those of Black race/ethnicity. CONCLUSION: The ACA-DCE broadened insurance coverage for young adults with cancer in California. Yet, only certain subgroups of patients have benefited from this policy.

RESUMEN

BACKGROUND: Secondary cancers account for 16% of all new cancer diagnoses, with breast cancer (BC) the most common secondary cancer. We have shown that secondary BC has unique characteristics and decreased survival compared with primary BC in adolescent and young adults (AYA; 15-39 years old). However, older BC populations are less well studied. METHODS: Females (age ≥ 15 years) diagnosed with primary BC during 1991-2015 (n = 377,167) and enrolled in the California Cancer Registry were compared with those with secondary BC (n = 37,625) by age (15-39, 40-64, ≥ 65 years). We examined BC-specific survival (BCSS) accounting for other causes of death as a competing risk using multivariable Cox proportional hazards regression. RESULTS: Most secondary BC patients were of older age (15-39, n = 777; 40-64, n = 15,848; ≥ 65, n = 21,000). Compared with primary BC treatment, secondary BCs were more often treated with mastectomy and less often with chemotherapy and/or radiation. BCSS was shorter in secondary BC patients than primary BC patients, but the survival difference between secondary and primary BC diminished with age [15-39 hazard ratio (HR): 2.09, 95% confidence interval (CI) 1.83-2.39; 40-64 HR: 1.51; 95% CI 1.44-1.58; ≥ 65 HR: 1.14; 95% CI 1.10-1.19]. Survival differences were most pronounced in women with hormone receptor positive disease and Hispanic and Asian/Pacific Islanders 40-64 years of age. CONCLUSIONS: When BC is diagnosed following a prior cancer of any organ site, BCSS is worse than when compared with patients for whom BC is the primary diagnosis, suggesting that we may need to tailor our treatments for women with secondary BC.

RESUMEN

Little is known about the incidence of late effects following non-Hodgkin lymphoma (NHL) among adolescent and young adult (AYA, 15-39 years) survivors. Using data from the California Cancer Registry linked to hospital discharge, we estimated the cumulative incidence of late effects at 10 years among AYAs diagnosed with NHL during 1996-2012, who survived ≥2 years. Cox proportional-hazards models were used to investigate the influence of sociodemographic and clinical factors on the occurrence of late effects. Of 4392 HIV-uninfected patients, the highest incident diseases were: endocrine (18·5%), cardiovascular (11·7%), and respiratory (5·0%), followed by secondary primary malignancy (SPM, 2·6%), renal and neurologic (2·2%), liver/pancreatic (2·0%), and avascular necrosis (1·2%). Among the 425 HIV-infected survivors, incidence was higher for all late effects, especially over threefold increased risk of SPM, compared to HIV-uninfected patients (8·1% vs. 2·6%). In multivariable models for HIV-uninfected patients, public or no health insurance (vs. private), residence in lower socioeconomic neighbourhoods (vs. higher), and receipt of a haematopoietic stem cell transplant were associated with a greater risk of most late effects. Our findings of substantial incidence of late effects among NHL AYA survivors emphasise the need for longterm follow-up and appropriate survivorship care to reduce morbidity and mortality in this vulnerable population.

RESUMEN

INTRODUCTION: The impact of splenectomy on venous thrombosis (VTE), abdominal thrombosis (abVTE) and sepsis in autoimmune hemolytic anemia (AIHA) is unclear. METHODS: Using the California Discharge Dataset 1991-2014, 4756 AIHA patients were identified. Cumulative incidences (CI) of VTE, abVTE, and sepsis were determined in patients with and without splenectomy. Using propensity score matching adjusted for competing risk of death, the association between VTE, abVTE and sepsis with splenectomy was determined. RESULTS: In those without splenectomy, the CIs of VTE, abVTE, and sepsis were 1.4%, 0.2%, and 4.3% respectively, compared to 4.4%, 3.0% and 6.7% with splenectomy. Splenectomy was associated with increased risk for VTE in immediate (HR 2.66, CI 1.36-5.23) and late (HR 3.29, CI 2.10-5.16) post-operative periods. AbVTE was increased in immediate post-operative period (HR 34.11, CI 4.93-236.11). Sepsis was only increased in late post-operative period (HR 2.20, CI 1.75-2.77). In multivariate models, older age, having >1 comorbidity and having VTE, abVTE, and sepsis were associated with increased mortality. Splenectomy was not associated with increased mortality. DISCUSSION: Splenectomy in AIHA was associated with significant early thrombotic risk and long-term morbidity. Future research should evaluate the role of splenectomy in AIHA patients, and potential long-term thrombotic and antibiotic prophylaxis.

RESUMEN

PURPOSE: The impact of gynecologic cancer on health-related quality of life (HRQOL) is not fully understood. To our knowledge, this is the first longitudinal study to measure HRQOL changes from before to after gynecologic cancer diagnosis in older women. METHODS: Data were obtained from the Surveillance, Epidemiology, and End Results - Medicare Health Outcomes Survey database. Women aged 65 and older who were diagnosed with cervical, ovarian, or uterine cancer between baseline and follow-up surveys (n = 248; mean time from diagnosis = 12.54 ± 7.11 months) were propensity-matched to cancer-free controls (n = 1240). Logistic regression was used to assess risk of functional impairments and depressive symptoms at follow-up. Changes in HRQOL, as measured by the Medical Outcomes Study Short Form-36 and Veterans RAND 12-Item Survey, were estimated with mixed effects linear models. RESULTS: Women who were within 12 months of diagnosis and women diagnosed with regional/distant disease had significantly greater odds than controls of impairment at follow-up. HRQOL declines were greatest in those with advanced disease, with the most notable changes from baseline to follow-up observed for role limitations due to emotional problems (-8.60 vs. -3.42 in controls), general health (-7.76 vs 0.10), and physical functioning (-7.70 vs. -1.67). There were significant decreases in physical functioning and role limitations due to emotional problems for all cancer patients regardless of time since diagnosis. CONCLUSIONS: Gynecologic cancer has significant impacts on physical and mental aspects of HRQOL in older women. Interventions are needed to reduce pain, provide support, and prepare patients for changes in functioning and health.

RESUMEN

BACKGROUND: Adolescents and young adults (AYAs) with public or no insurance experience later stage at diagnosis and worse overall survival compared with those with private insurance. However, prior studies have not distinguished the survival impact of continuous Medicaid coverage prior to diagnosis compared with gaining Medicaid coverage at diagnosis. METHODS: We linked a cohort of AYAs aged 15-39 who were diagnosed with 13 common cancers from 2005 to 2014 in the California Cancer Registry with California Medicaid enrollment files to ascertain Medicaid enrollment, with other insurance determined from registry data. We used Cox proportional hazards regression to evaluate the impact of insurance on survival, adjusting for clinical and demographic characteristics. RESULTS: Among 62 218 AYAs, over 65% had private/military insurance, 10% received Medicaid at diagnosis, 13.2% had continuous Medicaid, 4.1% had discontinuous Medicaid, 1.7% had other public insurance, 3% were uninsured, and 2.6% had unknown insurance. Compared with those with private/military insurance, individuals with Medicaid insurance had significantly worse survival regardless of when coverage began (received Medicaid at diagnosis: hazard ratio [95% confidence interval]: 1.51 [1.42-1.61]; continuously Medicaid insured: 1.42 [1.33-1.52]; discontinuous Medicaid: 1.64 [1.49, 1.80]). Analyses of those with Medicaid insurance only demonstrated slightly worse cancer-specific survival among those with discontinuous Medicaid or enrollment at diagnosis compared with those with continuous enrollment, but results were not significant stratified by cancer site. CONCLUSIONS AND RELEVANCE: AYAs with Medicaid insurance experience worse cancer-specific survival compared with those with private/military insurance, yet continuous enrollment demonstrates slight survival improvements, providing potential opportunities for future policy intervention.

RESUMEN

PURPOSE: Health-related quality of life (HRQOL) is an important prognostic factor in cancer patients. To date, no other studies have assessed the association between HRQOL measured before diagnosis and survival in older women with endometrial cancer. METHODS: The Surveillance, Epidemiology, and End Results - Medicare Health Outcomes Survey linked database was used to identify 995 women who were at least 65 years old and completed a survey before diagnosis with endometrial cancer. We obtained scores for 10 HRQOL scales, as measured by Medical Outcomes Study Short Form-36 and Veterans RAND 12-Item Survey, and data on activities of daily living (ADLs) impairments and depressive symptoms. Fine and Gray competing risks regression and Cox proportional hazards were used to estimate the association of HRQOL with endometrial cancer-specific and overall survival, respectively. RESULTS: Women who died had worse pre-diagnosis HRQOL than women who were still alive at the end of the study period. For every five-point increase in HRQOL score, overall survival improved by 5-9%. The strongest associations were observed for vitality (HR = 0.91, 95% CI 0.86, 0.97, p = 0.0021) and physical functioning (HR = 0.92, 95% CI 0.87, 0.97, p = 0.0010). ADL impairments were generally not predictive of survival, though depressive symptoms were significantly associated with increased hazard of death from all causes (HR = 1.34, 95% CI 1.00, 1.79, p = 0.0466). CONCLUSION: HRQOL measured before diagnosis with endometrial cancer has prognostic value. Having measures of HRQOL available at diagnosis may facilitate timely supportive care to improve survival.

RESUMEN

Sickle cell disease (SCD) patients have a higher incidence of certain cancers, but no studies have determined the impact of cancer on survival among SCD patients. SCD patients (n = 6423), identified from state-wide hospitalisation data, were linked to the California Cancer Registry (1988-2014). Multivariable Cox proportional hazards regression was used to examine survival. Among SCD patients, a cancer diagnosis was associated with a 3-fold increased hazard of death. Compared to matched cancer patients without SCD, SCD was associated with worse overall survival, but not cancer-specific survival, suggesting that SCD cancer patients should be treated with similar therapeutic intent.

RESUMEN

BACKGROUND: This population-based study considered the influence of rituximab on the survival of children (0-19 years), adolescents, and young adults (AYAs, 20-39 years) with diffuse large B-cell lymphoma (DLBCL), including patients with human immunodeficiency virus (HIV) infection. METHODS: Data on 642 children and AYAs diagnosed with DLBCL during 2001-2014 were obtained from the Greater Bay Area Cancer Registry in California. Facility-level reports provided treatment details. The Kaplan-Meier method estimated survival and Cox regression models examined the association between survival and rituximab use, adjusting for sociodemographic and clinical factors. RESULTS: Rituximab use increased from 2001-2007 to 2008-2014 among children (from 32% to 48%), AYAs (from 68% to 84%), and HIV patients (from 57% to 67%). Five-year survival was higher among children (91%) than AYAs (82%). On multivariable analysis, the hazard of death was 44% lower among rituximab recipients, and higher among uninsured patients, those with HIV, and those with advanced stage at diagnosis. HIV patients who received rituximab were 60% less likely to die than nonrecipients. CONCLUSIONS: Our study suggests a benefit of rituximab on the treatment of AYAs and HIV patients with DLBCL. The worse survival observed among HIV-positive and uninsured patients is of concern and calls for further investigation. Careful consideration should be given on whether to recommend rituximab more often on the front-line treatment of children and HIV-positive patients with DLBCL.
