BackgroundBoth health insurance status and race independently impact colon cancer (CC) care delivery and outcomes. The relative importance of these factors in explaining racial and insurance disparities is less clear, however. This study aimed to determine the association and interaction of race and insurance with CC treatment disparities.Study settingRetrospective cohort review of a prospective hospital-based database.Methods and findingsIn this cross-sectional study, patients diagnosed with stage I to III CC in the United States were identified from the National Cancer Database (NCDB; 2006 to 2016). Multivariable regression with generalized estimating equations (GEEs) were performed to evaluate the association of insurance and race/ethnicity with odds of receipt of surgery (stage I to III) and adjuvant chemotherapy (stage III), with an additional 2-way interaction term to evaluate for effect modification. Confounders included sex, age, median income, rurality, comorbidity, and nodes and margin status for the model for chemotherapy. Of 353,998 patients included, 73.8% (n = 261,349) were non-Hispanic White (NHW) and 11.7% (n = 41,511) were non-Hispanic Black (NHB). NHB patients were less likely to undergo resection [odds ratio (OR) 0.66, 95% confidence interval [CI] 0.61 to 0.72, p < 0.001] or to receive adjuvant chemotherapy [OR 0.83, 95% CI 0.78 to 0.87, p < 0.001] compared to NHW patients. NHB patients with private or Medicare insurance were less likely to undergo resection [OR 0.76, 95% CI 0.63 to 0.91, p = 0.004 (private insurance); OR 0.59, 95% CI 0.53 to 0.66, p < 0.001 (Medicare)] and to receive adjuvant chemotherapy [0.77, 95% CI 0.68 to 0.87, p < 0.001 (private insurance); OR 0.86, 95% CI 0.80 to 0.91, p < 0.001 (Medicare)] compared to similarly insured NHW patients. Although Hispanic patients with private and Medicare insurance were also less likely to undergo surgical resection, this was not the case with adjuvant chemotherapy. This study is mainly limited by the retrospective nature and by the variables provided in the dataset; granular details such as continuity or disruption of insurance coverage or specific chemotherapy agents or dosing cannot be assessed within NCDB.ConclusionsThis study suggests that racial disparities in receipt of treatment for CC persist even among patients with similar health insurance coverage and that different disparities exist for different racial/ethnic groups. Changes in health policy must therefore recognize that provision of insurance alone may not eliminate cancer treatment racial disparities.Scarlett Hao and colleagues utilize a national population database to investigate the association of race and health insurance in treatment disparities of colon cancer in US. 相似文献

ObjectiveUpdate information on racial disparities in ovarian cancer survival from the Surveillance, Epidemiology, and End Results (SEER) Program.MethodsData on women with epithelial ovarian cancer from the SEER Program between 1995–2015 were collected including; patient ID, age at diagnosis, year of diagnosis, surgery, chemotherapy, radiation, insurance status, region of registry, tumor grade, tumor histology, tumor summary stage, survival months, race/ethnicity, and vital status. Multivariable analyses were performed to examine overall survival, differences in survival by age at diagnosis, by year of diagnosis, risk of not receiving surgery, and risk of 12-month death across racial/ethnic groups.ResultsNon-Hispanic black women (n = 4261) had an increased risk of overall mortality (HR = 1.28, CI: 1.23–1.33) when compared to non-Hispanic white women (n = 47,475), which appears more pronounced among women diagnosed under age 50. Hispanic women (n = 7052) had no difference in survival when compared to non-Hispanic white women (HR = 1.03, CI: 0.99–1.07). Non-Hispanic Asian/PI women (n = 5008) exhibited slightly reduced risk (HR = 0.95, CI: 0.91–0.99) when compared to non-Hispanic white women. Risk of not receiving surgical intervention remains high among non-Hispanic black women and Hispanic women, when compared to non-Hispanic white women. Non-Hispanic black women, non-Hispanic Asian/PI women, and Hispanic women were all at significantly greater risk of dying within the first 12 months of cancer diagnosis when compared to non-Hispanic white women.ConclusionDisparities in survival remain across various racial/ethnic groups, when compared to non-Hispanic white women with ovarian cancer. These disparities should continue to be examined in an effort to decrease such gaps. 相似文献

Objective: The aim of our study was to compare the age-standardized incidence of esophageal cancer (EC) in Puerto Ricans (PRs) with that for non-Hispanic White (NHW), non-Hispanic Black (NHB), and Hispanic (USH), groups in the United States (US) as reported by the Surveillance, Epidemiology, and End Results program for the 1992–2005 period. Methods: We computed the age-standardized and age-specific incidence (per 100,000 individuals) of EC during 1992–2005 using the World Standard Population as reference. The percent changes for age-standardized rates (ASR), from 1992–1996 to 2001–2005, were calculated. The relative risks (RR) and the standardized rate ratios (SRR) were estimated, along with 95% confidence intervals (CIs). Results: The ASR of adenocarcinomas (AC) showed increases for most racial/ethnic groups from 1992–1996 to 2001–2005. All racial/ethnic groups showed ASR reductions for squamous cell carcinomas (SCC). For both sexes, PRs had lower AC incidences than NHW and USH but higher than NHB. For those younger than 80 years of age, PR men showed higher SCC incidences than NHW but lower than NHB (P < 0.05). The incidence of SCC was about two times higher in PR men than USH men (SRR: 2.16; 95% CI = 1.65–2.88). Among women, the RR for SCC increased with age when comparing PRs to groups in the US. Conclusion: Incidence disparities were observed between PRs and other racial/ethnic groups in the US. These differences and trends may reflect lifestyles of each racial/ethnic group. Further studies are warranted to explain these disparities. 相似文献

BackgroundThe study aimed to examine racial/ethnic differences in chemotherapy utilization by breast cancer subtype.MethodsData on female non-Hispanic white (NHW), non-Hispanic black (NHB), and Hispanic stage I-III breast cancer patients diagnosed in 2011 were obtained from a project to enhance population-based National Program of Cancer Registry data for Comparative Effectiveness Research. Hormone receptor (HR) and human epidermal growth factor receptor 2 (HER2) were used to classify subtypes: HR+/HER2-; HR+/HER2+; HR-/HER2-; and HR-/HER2 + . We used multivariable logistic regression models to examine the association of race/ethnicity with three outcomes: chemotherapy (yes, no), neo-adjuvant chemotherapy (yes, no), and delayed chemotherapy (yes, no). Covariates included patient demographics, tumor characteristics, Charlson Comorbidity Index, other cancer treatment, and participating states/areas.ResultsThe study included 25,535 patients (72.1% NHW, 13.7% NHB, and 14.2% Hispanics). NHB with HR+/HER2- (adjusted odds ratio [aOR] 1.22, 95% CI 1.04–1.42) and Hispanics with HR-/HER2- (aOR 1.62, 95% CI 1.15–2.28) were more likely to receive chemotherapy than their NHW counterparts. Both NHB and Hispanics were more likely to receive delayed chemotherapy than NHW, and the pattern was consistent across each subtype. No racial/ethnic differences were found in the receipt of neo-adjuvant chemotherapy.ConclusionsCompared to NHW with the same subtype, NHB with HR+/HER2- and Hispanics with HR-/HER2- have higher odds of using chemotherapy; however, they are more likely to receive delayed chemotherapy, regardless of subtype. Whether the increased chemotherapy use among NHB with HR+/HER2- indicates overtreatment needs further investigation. Interventions to improve the timely chemotherapy among NHB and Hispanics are warranted. 相似文献

PurposeThe population of adolescent and young adult (AYA, ages 15–39 years) diffuse large B-cell lymphoma (DLBCL) survivors is growing, however long-term overall survival patterns and disparities are largely unknown.MethodsThe current study utilized the Surveillance, Epidemiology, and End Results (SEER) registry to assess the impact of race/ethnicity, sex, socioeconomic status, and rurality on long-term survival in 5-year DLBCL survivors using an accelerated failure time model.ResultsIncluded were 4767 5-year survivors of AYA DLBCL diagnosed between the years 1980 and 2009 with a median follow-up time of 13.4 years. Non-Hispanic Black survivors had significantly worse long-term survival than non-Hispanic White survivors (Survival Time Ratio (STR): 0.53, p < 0.0001). Male sex (STR: 0.57, p < 0.0001) and older age at diagnosis were also associated with reduced long-term survival. There was no evidence that survival disparities improved over time.ConclusionsRacial disparities persist well into survivorship among AYA DLBCL survivors. Studies investigating specific factors associated with survival disparities are urgently needed to better address these disparities. 相似文献

BackgroundGastrointestinal (GI) cancers represent a diverse group of diseases. We assessed differences in geographic and racial disparities in cancer-specific mortality across subtypes, overall and by patient characteristics, in a geographically and racially diverse US population.MethodsClinical, sociodemographic, and treatment characteristics for patients diagnosed during 2009–2014 with colorectal cancer (CRC), pancreatic cancer, hepatocellular carcinoma (HCC), or gastric cancer in Georgia were obtained from the Surveillance, Epidemiology, and End Results Program database. Patients were classified by geography (rural or urban county) and race and followed for cancer-specific death. Multivariable Cox proportional hazards models were used to calculate stratified hazard ratios (HR) and 95% confidence intervals (CIs) for associations between geography or race and cancer-specific mortality.ResultsOverall, 77% of the study population resided in urban counties and 33% were non-Hispanic Black (NHB). For all subtypes, NHB patients were more likely to reside in urban counties than non-Hispanic White patients. Residing in a rural county was associated with an overall increased hazard of cancer-specific mortality for HCC (HR = 1.15, 95% CI = 1.02–1.31), pancreatic (HR = 1.11, 95% CI = 1.03–1.19), and gastric cancer (HR = 1.17, 95% CI = 1.03–1.32) but near-null for CRC. Overall racial disparities were observed for CRC (HR = 1.18, 95% CI = 1.11–1.25) and HCC (HR = 1.12, 95% CI = 1.01–1.24). Geographic disparities were most pronounced among HCC patients receiving surgery. Racial disparities were pronounced among CRC patients receiving any treatment.ConclusionGeographic disparities were observed for the rarer GI cancer subtypes, and racial disparities were pronounced for CRC. Treatment factors appear to largely drive both disparities. 相似文献

BackgroundThere are documented racial/ethnic and sex differences in pediatric cancer survival; however, it is unknown whether pediatric cancer survival disparities exist when race/ethnicity and sex are considered jointly.MethodsUsing SEER data (2000–2017), we estimated survival differences by race/ethnicity within sexes and by sex within race/ethnicity (White, Black, Hispanic, and Asian/Pacific Islander [API]) for 17 cancers in children aged (0–19 years). Kaplan-Meier curves (Log-Rank p-values) were assessed. Cox regression was used to estimate hazards ratios (HRs) and 95 % confidence intervals (95 % CIs) between race/ethnicity/sex and cancer.ResultsWe included 51,759 cases (53.6 % male, 51.9 % White). There were statistically significant differences in 18-year survival by race/ethnicity-sex for 12/17 cancers. Within sexes, minorities had an increased risk of death compared to Whites for various cancers including acute lymphoblastic leukemia (ALL) (females: HispanicHR: 1.78, 95 % CI: 1.52, 2.10; BlackHR: 1.70, 95 % CI: 1.29, 2.24; APIHR: 1.42, 95 % CI: 1.07–1.89; males ALL: HispanicHR: 1.58, 95 % CI: 1.39,1.79; BlackHR: 1.57, 95 % CI: 1.26,1,95; API-HR: 1.39, 95 % CI: 1.11, 1.75) and astrocytoma (females: HispanicHR: 1.49, 95 % CI: 1.19, 1.85; BlackHR: 1.67, 95 % CI: 1.29, 2.17; API-HR: 1.51, 95 % CI: 1.05, 2.15; males: HispanicHR:1.27, 95 % CI: 1.04, 1.56; BlackHR: 1.69, 95 % CI: 1.32, 2.17; API-HR: 1.92, 95 % CI: 1.43, 2.58). Sex differences in survival within racial/ethnic groups were observed for White (ALL, osteosarcoma), Hispanic (medulloblastoma), and API (Primitive Neuro-Ectodermal Tumor [PNET]) children.ConclusionsThere are disparities in survival by both race/ethnicity and sex highlighting the societal and biologic influences these features have on survival in children with cancer. 相似文献

BackgroundObesity prevalence remains high among children of Pacific Islander (PI) origin, Filipino (FI), and American Indian/Alaska Native (AIAN) origins in the United States. While school nutrition policies may help prevent and reduce childhood obesity, their influences specifically among PI, FI, and AIAN children remain understudied. We evaluated the association of the California (CA) state school nutrition policies for competitive food and beverages and the federal policy for school meals (Healthy, Hunger-Free Kids Act of 2010 (HHFKA 2010)) with overweight/obesity among PI, FI, and AIAN students.Methods and findingsWe used an interrupted time series (ITS) design with FitnessGram data from 2002 to 2016 for PI (78,841), FI (328,667), AIAN (97,129), and White (3,309,982) students in fifth and seventh grades who attended CA public schools. Multilevel logistic regression models estimated the associations of the CA school nutrition policies (in effect beginning in academic year 2004 to 2005) and HHFKA 2010 (from academic year 2012 to 2013) with overweight/obesity prevalence (above the 85 percentile of the age- and sex-specific body mass index (BMI) distribution). The models were constructed separately for each grade and sex combination and adjusted for school district-, school-, and student-level characteristics such as percentage of students eligible for free and reduced price meals, neighborhood income and education levels, and age. Across the study period, the crude prevalence of overweight/obesity was higher among PI (39.5% to 52.5%), FI (32.9% to 36.7%), and AIAN (37.7% to 45.6%) children, compared to White (26.8% to 30.2%) students. The results generally showed favorable association of the CA nutrition policies with overweight/obesity prevalence trends, although the magnitudes of associations and strengths of evidence varied among racial/ethnic subgroups. Before the CA policies went into effect (2002 to 2004), overweight/obesity prevalence increased for White, PI, and AIAN students in both grades and sex groups as well as FI girls in seventh grade. After the CA policies took place (2005 to 2012), the overweight/obesity rates decreased for almost all subgroups who experienced increasing trends before the policies, with the largest decrease seen among PI girls in fifth grade (before: log odds ratio = 0.149 (95% CI 0.108 to 0.189; p < 0.001); after: 0.010 (−0.005 to 0.025; 0.178)). When both the CA nutrition policies and HHFKA 2010 were in effect (2013 to 2016), declines in the overweight/obesity prevalence were seen among White girls and FI boys in fifth grade. Despite the evidence of the favorable association of the school nutrition policies with overweight/obesity prevalence trends, disparities between PI and AIAN students and their White peers remained large after the policies took place. As these policies went into effect for all public schools in CA, without a clear comparison group, we cannot conclude that the changes in prevalence trends were solely attributable to these policies.ConclusionsThe current study found evidence of favorable associations of the state and federal school nutrition policies with overweight/obesity prevalence trends. However, the prevalence of overweight/obesity continued to be high among PI and AIAN students and FI boys. There remain wide racial/ethnic disparities between these racial/ethnic minority subgroups and their White peers. Additional strategies are needed to reduce childhood obesity and related disparities among these understudied racial/ethnic populations.Dr. Mika Matsuzaki and co-authors found evidence of favorable associations between state and federal school nutrition policies with overweight/obesity prevalence trends among children of Pacific Islander origin, Filipino, and American Indian/Alaska Native origins in the United States. 相似文献

Data from National Health and Nutrition Examination Survey for the period 2011–2012 were used to determine normal reference ranges and percentile distributions for manganese (Mn) and selenium (Se) in blood by gender, age, race/ethnicity, socioeconomic status as determined by annual family income, and smoking status. The effect of gender, age, race/ethnicity, family income, and smoking status on the levels of Mn and Se was also determined by fitting regression models. Males had lower adjusted levels of Mn and higher adjusted levels of Se than females. Adjusted levels of Mn decreased with increase in age but adjusted levels of Se were lower in adolescents aged 12–19 years than adults aged 20–64 years. Non-Hispanic black (NHB) had the lowest levels of both Mn and Se and non-Hispanic Asians (NHAS) had the highest levels of both Mn and Se. Non-Hispanic white (NHW) and NHB had lower levels of Mn than Hispanics (HISP) and NHAS. NHB and HISP had lower levels of Se than NHW and NHAS. Low annual income (<$20,000) was associated with lower levels of Se than high annual income (≥$55,000). Smoking negatively affected the adjusted levels of Se among seniors aged ≥65 years but this was not observed in other age groups. Mn levels were not affected by smoking. 相似文献

ObjectiveThe incidence of thyroid cancer has been steadily increasing. Several studies have identified gender and racial/ethnic differences in the incidence and prognosis of thyroid cancer. In this study, we sought to determine if the stage of presentation and survival rate of patients with thyroid cancer in the United States is affected by geographic region.MethodsUsing the Surveillance, Epidemiology, and End Results (SEER) database, we identified 100,404 patients diagnosed with thyroid cancer from 1973 through 2009. We assessed historical stage of diagnosis and cancer-free survival rate according to geographic region. To compare stages of diagnosis, we used multinomial logistic regression. To compare survival rates, we used Cox proportional hazards regression. Models were adjusted for age, year of diagnosis, cancer type, registry site, race/ethnicity, and stage.ResultsOf 100,404 patients, 52,902 (52.7%) were from the West, 17,915 (17.8%) from the East, 15,302 (15.2%) from the South, and 14,285 (14.2%) from the Midwest. Overall, most patients presented with localized disease. Those from the West had a higher risk of presenting with regional and distant metastases. When we double-stratified by cancer subtype and racial group, we found no significant associations between geographic region and cancer-free survival rate.ConclusionThe presentation stage and survival rate of patients with thyroid cancer differs by geographic region, but not within separate racial/ethnic groups.

BackgroundBoth minority race and lack of health insurance are risk factors for lower survival in colorectal cancer (CRC) but the interaction between the two factors has not been explored in detail.MethodsOne to 5-year survival by race/ethnic group and insurance type for patients with CRC diagnosed in 2007-13 and registered in the Surveillance Epidemiology, and EndResultsdatabase were explored. Shared frailty models were computed to further explore the association between CRC specific survival and insurance status after adjustment for demographic and treatment variables.ResultsAge-adjusted 5-year survival estimates were 70.4% for non-Hispanic whites (nHW), 62.7% for non-Hispanic blacks (nHB), 70.2% for Hispanics, 64.7% for Native Americans, and 73.1% for Asian/Pacific Islanders (API). Survival was greater for patients with insurance other than Medicaid for all races, but the differential in survival varied with race, with the greatest difference being seen for nHW at +25.0% and +20.2%, respectively, for Medicaid and uninsured versus other insurance. Similar results were observed for stage- and age-specific analyses, with survival being consistently higher for nHW and API compared to other groups. After confounder adjustment, hazard ratios of 1.53 and 1.50 for CRC-specific survival were observed for Medicaid and uninsured. Racial/ethnic differences remained significant only for nHB compared to nHW.ConclusionsRace/ethnic group and insurance type are partially independent factors affecting survival expectations for patients diagnosed with CRC. NHB had lower than expected survival for all insurance types. 相似文献

BackgroundWhile racial disparity in colorectal cancer survival have previously been studied, whether this disparity exists in patients with metastatic colorectal cancer receiving care at safety net hospitals (and therefore of similar socioeconomic status) is poorly understood.MethodsWe examined racial differences in survival in a cohort of patients with stage IV colorectal cancer treated at the largest safety net hospital in the New England region, which serves a population with a majority (65%) of non-Caucasian patients. Data was extracted from the hospital’s electronic medical record. Survival differences among different racial and ethnic groups were examined graphically using Kaplan-Meier analysis. A univariate cox proportional hazards model and a multivariable adjusted model were generated.ResultsBlack patients had significantly lower overall survival compared to White patients, with median overall survival of 1.9 years and 2.5 years respectively. In a multivariate analysis, Black race posed a significant hazard (HR 1.70, CI 1.01–2.90, p = 0.0467) for death. Though response to therapy emerged as a strong predictor of survival (HR = 0.4, CI = 0.2-0.7, p = 0.0021), it was comparable between Blacks and Whites.ConclusionsDespite presumed equal access to healthcare and socioeconomic status within a safety-net hospital system, our results reinforce findings from previous studies showing lower colorectal cancer survival in Black patients, and also point to the importance of investigating other factors such as genetic and pathologic differences. 相似文献

It has not been determined whether implementation of combined prevention programming for persons who inject drugs reduce racial/ethnic disparities in HIV infection. We examine racial/ethnic disparities in New York City among persons who inject drugs after implementation of the New York City Condom Social Marketing Program in 2007. Quantitative interviews and HIV testing were conducted among persons who inject drugs entering Mount Sinai Beth Israel drug treatment (2007–2014). 703 persons who inject drugs who began injecting after implementation of large-scale syringe exchange were included in the analyses. Factors independently associated with being HIV seropositive were identified and a published model was used to estimate HIV infections due to sexual transmission. Overall HIV prevalence was 4%; Whites 1%, African-Americans 17%, and Hispanics 4%. Adjusted odds ratios were 21.0 (95% CI 5.7, 77.5) for African-Americans to Whites and 4.5 (95% CI 1.3, 16.3) for Hispanics to Whites. There was an overall significant trend towards reduced HIV prevalence over time (adjusted odd ratio = 0.7 per year, 95% confidence interval (0.6–0.8). An estimated 75% or more of the HIV infections were due to sexual transmission. Racial/ethnic disparities among persons who inject drugs were not significantly different from previous disparities. Reducing these persistent disparities may require new interventions (treatment as prevention, pre-exposure prophylaxis) for all racial/ethnic groups. 相似文献

IntroductionThe Affordable Care Act's (ACA) preventive services provision (PSP) removes copayments for preventive services such as cancer screening. We examined: 1) whether a shift in breast cancer stage occurred, and 2) the impact of the provision on racial/ethnic disparities in stage.Materials and methodsData from the National Cancer Database were used. The pre- and post-PSP periods were identified as 2007–2009 and 2011–2013, respectively. Proportion differences (PDs) and 95% confidence Intervals (CIs) were calculated.ResultsAll three racial/ethnic groups experienced a statistically significant shift toward Stage I breast cancer. Pre-PSP, the black:white disparity in Stage I cancer was −9.5 (95% CI: −8.9, −10.4) and the Latina:white disparity was −5.2 (95% CI: −4.0, −6.1). Post-PSP, the disparities improved slightly.DiscussionPreliminary data suggest that the ACA's PSP may have a meaningful impact on cancer stage overall and by race/ethnicity. However, more time may be needed to see reductions in disparities. 相似文献

The racial/ethnic disparities in DNA methylation patterns indicate that molecular markers may play a role in determining the individual susceptibility to diseases in different ethnic groups. Racial disparities in DNA methylation patterns have been identified in prostate cancer, breast cancer and colorectal cancer and are related to racial differences in cancer prognosis and survival. 相似文献

BackgroundThere are well-known racial/ethnic disparities in maintaining healthy lifestyle behaviors throughout cancer survivorship among US-born women. Less is known about these associations among women born outside the US, as these women may experience disparities in survivorship care due to the lack of access to culturally appropriate health services. We evaluated disparities in the associations between race/ethnicity and US nativity and the likelihood of meeting recommendations for maintaining a healthy lifestyle during cancer survivorship.Methods2044 female cancer survivors contributed data from the National Health and Nutrition Examination Survey (NHANES) (1999–2018). Adjusted odds ratios (aORs) and 95 % confidence intervals (CIs) were calculated with multivariable logistic regression models to measure the association between independent variables (race/ethnicity, US nativity, length of time in the US) and outcomes (obesity, meeting weekly physical activity (PA) recommendations, smoking history, alcoholic drinks/day) overall and by comorbidity.ResultsMost survivors were breast cancer survivors (27.6 %), non-Hispanic white (64.2 %), and US native (84.5 %). Compared to US native survivors, foreign-born survivors were less likely (aOR, 0.30, 95 % CI, 0.10–0.87) to not meet PA recommendations, while foreign-born survivors living in the US ≥ 15 years were 2.30 times more likely (95 % CI, 1.12–4.73) to not meet PA recommendations. Having at least one comorbidity modified (p-interaction< 0.05) the relationships between US nativity and length of time in the US.ConclusionOur findings provide new evidence for disparities in maintaining healthy lifestyle behaviors among female cancer survivors and can help inform lifestyle interventions for female cancer survivors from different racial/ethnic backgrounds. 相似文献

AimTo determine the differential effect of the treatment periods on the survival of patients with stage IV serous papillary peritoneal carcinoma (SPPC), fallopian tube cancers, and epithelial ovarian cancers (EOC).MethodsThis was an exploratory, population-based observational study of all patients with stage IV SPPC, fallopian tube cancers, and EOC collected from the SEER Research Data 1973–2017. The study period was divided into three time-periods: platinum combinations before the taxane era (1990–1995), platinum plus taxane chemotherapy era (1996–2013), and bevacizumab era (2014–2017).ResultsA total of 9828 patients were eligible for analyses: SPPC (3898 patients; 39.7%), fallopian tube cancers (1290 patients; 13.1%) and EOC (4640 patients, 47.2%). In the 1990–1995 era, the 3-year cause-specific survival was 40% for SPPC, 53% for fallopian tube cancers, and 40% for POC. In the following era 1993–2013, the 3-year cause-specific survival increased to 55% for SPPC, 74% for fallopian tube cancers, and 45% for POC. The last era 2014–2017 showed a 3-year cause-specific survival of 64%, 67%, and 45% for patients with SPPC, fallopian tube cancers, and POC, respectively. The differences in cause-specific survival were statistically significant for patients with SPPC (p=0.004). Multivariable analysis showed that the treatment eras and age at diagnosis were associated with cause-specific survival.ConclusionThe results of this study are hypothesis-generating and cannot be considered conclusive given the inherent limitations of registry analysis. Subgroup analyses of the phase III randomized controlled trials, by tumor subset (EOC, fallopian tube cancer, and SPPC) would shed more light on the differential effects of novel therapies. 相似文献

BackgroundRacial (Black vs. White) disparities in breast cancer survival have proven difficult to mitigate. Targeted strategies aimed at the primary factors driving the disparity offer the greatest potential for success. The purpose of this study was to use multiple mediation analysis to identify the most important mediators of the racial disparity in breast cancer survival.MethodsThis was a retrospective cohort study of non-Hispanic Black and non-Hispanic White women diagnosed with invasive breast cancer in Florida between 2004 and 2015. Cox regression was used to obtain unadjusted and adjusted hazard ratios (HR) with 95% confidence intervals (CI) for the association of race with 5- and 10-year breast cancer death. Multiple mediation analysis of tumor (advanced disease stage, tumor grade, hormone receptor status) and treatment-related factors (receipt of surgery, chemotherapy, radiotherapy, and hormone therapy) was used to determine the most important mediators of the survival disparity.ResultsThe study population consisted of 101,872 women of whom 87.0% (n = 88,617) were White and 13.0% were Black (n = 13,255). Black women experienced 2.3 times (HR, 2.27; 95% CI, 2.16–2.38) the rate of 5-year breast cancer death over the follow-up period, which decreased to a 38% increased rate (HR, 1.38; 95% CI, 1.31–1.45) after adjustment for age and the mediators of interest. Combined, all examined mediators explained 73% of the racial disparity in 5-year breast cancer survival. The most important mediators were: (1) advanced disease stage (44.8%), (2) nonreceipt of surgery (34.2%), and (3) tumor grade (18.2%) and hormone receptor status (17.6%). Similar results were obtained for 10-year breast cancer death.ConclusionThese results suggest that additional efforts to increase uptake of screening mammography in hard-to-reach women, and, following diagnosis, access to and receipt of surgery may offer the greatest potential to reduce racial disparities in breast cancer survival for women in Florida. 相似文献

Purpose
To examine the associations between area-level socioeconomic attributes and stage of esophageal adenocarcinoma diagnoses in 16 SEER cancer registries during 2000-2007.Methods
Odds ratios (OR) and 95% confidence intervals (CI) were calculated using multivariable logistic regression models to assess the relationship between distant-stage esophageal adenocarcinoma and individual, census tract, and county-level attributes.Results
Among cases with data on birthplace, no significant association was seen between reported birth within versus outside the United States and distant-stage cancer (adjusted OR=1.02, 95% CI: 0.85-1.22). Living in an area with a higher percentage of residents born outside the United States than the national average was associated with distant-stage esophageal adenocarcinoma; census tract level: >11.8%, (OR=1.10, 95% CI:1.01–1.19), county level: >11.8%, (OR=1.14, 95% CI:1.05-1.24). No association was observed between median household income and distant-stage cancer at either census tract or county levels.Conclusion
The finding of greater odds of distant-stage esophageal adenocarcinoma among cases residing in SEER areas with higher proportion of non-U.S. Natives suggests local areas where esophageal cancer control efforts might be focused. Missing data at the individual level was a limitation of the present study. Furthermore, inconsistent associations with foreign birth at individual- versus area-levels cautions against using area-level attributes as proxies for case attributes. 相似文献20.

ObjectivesTo assess outcomes and treatment patterns as a function of time in stage IS pure testicular seminoma patients using a population-based analysis.MethodsOne thousand one hundred and fifty-two stage I testicular seminoma patients with normal alpha-fetoprotein levels were identified in the Surveillance, Epidemiology, and End Results (SEER) database between 1998 and 2005. Three hundred and twenty-three of these patients had persistent elevations of their serum lactate dehydrogenase (LDH) and/or beta subunit of human chorionic gonadotropin (bHCG) level post-orchiectomy, i.e., “stage IS” disease.ResultsMedian follow-up was 86 months. There was persistent elevation of LDH or bHCG levels post-orchiectomy in 19% and 15% stage I patients, respectively. Post-orchiectomy LDH and bHCG did not predict overall survival (OS) or cause-specific survival (CSS) in stage IS patients. There was a decrease in utilization of adjuvant RT in stage IS patients from 1998 (100%) to 2005 (58%, p = .01). The annual percentage decrease in RT utilization for stage IS patients was −5.4% (95% confidence interval: −7.7% to −3.9%). Modern, linear accelerator-based RT was associated with an improvement in OS. However, longer follow up is necessary to determine if the OS benefit persists.ConclusionsPost-orchiectomy LDH and bHCG did not predict OS or CSS in stage IS patients. There was a steady decrease in utilization of adjuvant RT in the United States in stage IS testicular seminoma patients between 1998 and 2005. This may be due to the increasing popularity of chemotherapy or active surveillance. 相似文献
