OBJECTIVES: Depression is associated with high healthcare expenditures, and depression treatment may reduce healthcare expenditures. However, to date, there have not been any studies on the effect of depression treatment on healthcare expenditures among cancer survivors. Therefore, this study examined the association between depression treatment and healthcare expenditures among elderly with depression and incident cancer. METHODS: The current study utilized a retrospective longitudinal study design using the linked Surveillance, Epidemiology and End Results (SEER)-Medicare database...

Colorectal cancer is the second most common cancer in females and the third most common cancer diagnosed in males (Torre et al.(1)). In 2012, there were about 1.4 million cases and 693,900 deaths due to colorectal cancer worldwide. It is more common in developed countries, and North America, Europe, and Australia have the highest incidence rates. In the United States, adults have a 5% chance of developing colorectal cancer (Cancer of the colon and rectum-SEER stat fact sheets(2)). Due to the high prevalence of colorectal cancer, understanding the mechanism underlying its initiation and progression in order to find better therapeutic agents will have a high impact in the field of oncology and may improve the treatment of other cancers with shared mechanistic properties...

Colorectal cancer (CRC) incidence and mortality are rising among young adults. Our aim was to contrast the relative incidence and mortality of CRC to other common cancers among young adults in the USA. We used Surveillance, Epidemiology, and End Results registry data to compare cancer site-specific and age-specific mortality and incident rates for adults younger than age 50. We summarized extracted data, both overall, and stratified by sex. We found CRC was the third leading cause of cancer death among adults younger than age 50, after breast and lung cancer (1...

PURPOSE: Hereditary hemorrhagic telangiectasia (HHT) is a genetic disorder characterized by deficiency in endoglin, an angiogenic protein. We previously showed that HHT, in which systemic endoglin expression is reduced, was associated with better survival outcomes in cancer patients (Duarte et al. in Cancer Epidemiol Biomarkers Prev 23:117-125, 2014). Here, we evaluated whether HHT was associated with reduced cancer incidence. METHODS: A matched case-control analysis using SEER Medicare was conducted to evaluate the effect of HHT on diagnosis with breast, colorectal, lung, or prostate cancer between 2000 and 2007 (n = 633,162)...

BACKGROUND & AIMS: The incidence of colorectal cancer (CRC) in the U.S. is increasing among adults younger than age 50 years, but incidence has decreased among older populations after population-based screening was recommended in the late 1980s. Blacks have higher incidence than whites. These patterns have prompted suggestions to lower the screening age for average-risk populations or in blacks. At the same time, there has been controversy over whether reductions in CRC incidence can be attributed to screening...

PURPOSE: Colorectal cancer (CRC) incidence and mortality in the United States have steadily declined since the 1980s, but racial and socioeconomic disparities remain. The influence of geographic factors is poorly understood and may be affected by evolving insurance coverage and screening test uptake. We characterized temporal trends in the association between geographic and sociodemographic factors and CRC outcomes. METHODS: We used the 1973-2010 SEER-Medicare files to identify patients aged ≥65 years with and without CRC...

BACKGROUND: The predictive accuracy of the American Joint Committee on Cancer (AJCC) stages of colorectal cancer (CRC) is mediocre. This study aimed to develop postoperative nomograms to predict cancer-specific survival (CSS) and overall survival (OS) after CRC resection without preoperative therapy. METHODS: Eligible patients with stage I to IV CRC (n = 56072) diagnosed from 2004 to 2010 were selected from the Surveillance, Epidemiology, and End Results (SEER) database...

BACKGROUND: Physicians routinely factor comorbidities into diagnostic and treatment decisions. Analyses of treatment patterns and outcomes using the National Cancer Data Base (NCDB) usually adjust for comorbidities; however, the completeness of comorbidity ascertainment in the NCDB has never been assessed. We compared the prevalence of comorbidities captured in the NCDB and Surveillance, Epidemiology, and End Results (SEER)-Medicare among female breast, non-small-cell lung, and colorectal cancer patients aged ≥66...

OBJECTIVES: To use place-of-service (POS) codes in the Medicare hospice claims files to document where elderly hospice users with cancer die. DESIGN: Retrospective cohort study. SETTING: Surveillance, Epidemiology, and End Results (SEER) cancer registry areas. PARTICIPANTS: Elderly Medicare beneficiaries who died of lung, breast, colorectal, or pancreatic cancer in 2007 and 2008 (N = 46,037). MEASUREMENT: Use of hospice, place of service at death (home, nursing home, hospital, inpatient hospice, other), length of stay in hospice...

BACKGROUND: Increased life expectancy, growth of minority populations, and advances in cancer screening and treatment have resulted in an increasing number of older, racially diverse cancer survivors. Potential black/white disparities in cancer incidence, stage, and survival among the oldest old (≥85 years) were examined using data from the SEER Program of the National Cancer Institute. METHODS: Differences in cancer incidence and stage at diagnosis were examined for cases diagnosed within the most recent 5-year period, and changes in these differences over time were examined for white and black cases aged ≥85 years...

BACKGROUND: We determined whether the current SEER registries are representative of the nation's cancer cases or the socio-demographic characteristics. METHODS: We used breast cancer (BC) and colorectal cancer (CRC) cases diagnosed 2004-2009 from the US Cancer Statistics (USCS) database. Cases were classified into groups residing in SEER coverage areas and the other areas. We compared difference between SEER and non-SEER areas in: age-race-specific proportions of late-stage BC or CRC, area demographics and socioeconomic factors, and data quality...

BACKGROUND: Uninsured patients have poor access to screening colonoscopy and subsequently present with advanced stages of colorectal cancer (CRC) that beget worse outcomes and higher total costs. Providing pro bono colonoscopies to uninsured patients at high risk for CRC can detect early stage disease and be cost-effective. STUDY DESIGN: Patients considered at increased risk for CRC were offered free screening colonoscopies. Patient data from these colonoscopies were collected during a 12-month period, and the incidence of CRC was compared with a control group of uninsured patients from the Surveillance, Epidemiology, and End Results (SEER) registry...

Prognostic role of surgical resection of the primary tumor and baseline CEA among patients with synchronous stage IV colorectal cancer (CRC) remains an area of debate. The objective of this study was to determine the prognostic value of baseline CEA and surgical resection of the primary among patients with synchronous stage IV CRC in the era of modern chemotherapy and biologic therapy. The Surveillance, Epidemiology and End Results Registry was searched to identify patients with synchronous stage IV CRC diagnosed between 2004 and 2009...

INTRODUCTION: There are concerns about potential overuse of colorectal cancer (CRC) screening services among average-risk individuals older than age 75 years. MATERIALS AND METHODS: Using a 5% random noncancer sample of Medicare beneficiaries who resided in the SEER areas, we examined rates of CRC screening adherence, defined by the Medicare coverage policy, among average-risk fee-for-service beneficiaries age 76 to 95 years from 2002 to 2010. The two outcomes are the status of overall CRC screening adherence, and the status of adherence to colonoscopy (v other modalities) conditional on patient adherence...
