ABSTRACT BACKGROUND: The research goals of the Cancer Care Outcomes Research and Surveillance (CanCORS) Consortium are to determine how characteristics and beliefs of patients, providers, and health care organizations influence the treatments and outcomes of individuals with newly diagnosed lung and colorectal cancers. As CanCORS results will inform national policy, it is important to know how they generalize to the United States population with these cancers. RESEARCH DESIGN: This study assessed the representativeness of the CanCORS cohort of 10,547 patients with lung cancer (LC) or colorectal cancer (CRC) enrolled between 2003 and 2005. We compared characteristics (sex, race, age, and disease stage) with the Surveillance, Epidemiology, and End Results (SEER) population of 234,464 patients with new onset of these cancers during the CanCORS recruitment period. RESULTS: The CanCORS sample is well matched to the SEER Program for both cancers. In CanCORS, 41% LC/47% CRC were female versus 47% LC/49% CRC in SEER. African American, Hispanic, and Asian cases differed by no more than 5 percentage points between CanCORS and SEER. The SEER population is slightly older, with the percentage of patients older than 75 years 33.1% LC/37.3% CRC in SEER versus 26.9% LC/29.4% in CanCORS, and also has a slightly higher proportion of early stage patients. We also found that the CanCORS cohort was representative within specific SEER regions that map closely to CanCORS sites. CONCLUSIONS: This study demonstrates that the CanCORS Consortium was successful in enrolling a demographically representative sample within the CanCORS regions.

    ABSTRACT: BACKGROUND Current literature suggests that racial/ethnic minority survivors may be more likely than whites to experience economic hardship after a cancer diagnosis; however, little is known about such hardship.METHODS Patients with lung cancer (LC) and colorectal cancer (CRC) participating in the Cancer Care Outcomes Research and Surveillance (CanCORS) Consortium were surveyed approximately 4 months (baseline) and 12 months (follow-up) after diagnosis. Economic hardship at follow-up was present if participants 1) indicated difficulty living on household income; and/or 2) for the following 2 months, anticipated experiencing hardships (inadequate housing, food, or medical attention) or reducing living standards to the bare necessities of life. The authors tested whether African Americans (AAs) and Hispanics were more likely than whites to experience economic hardship controlling for sex, age, education, marital status, cancer stage, treatment, and economic status at baseline (income, prescription drug coverage).RESULTSOf 3432 survivors (39.7% with LC, 60.3% with CRC), 14% were AA, 7% were Hispanic, and 79% were white. AAs and Hispanics had lower education and income than whites. Approximately 68% of AAs, 58% of Hispanics, and 44.5% of whites reported economic hardship. In LC survivors, the Hispanic-white disparity was not significant in unadjusted or adjusted analyses, and the AA-white disparity was explained by baseline economic status. In CRC survivors, the Hispanic-white disparity was explained by baseline economic status, and the AA-white disparity was not explained by the variables that were included in the model.CONCLUSIONS Economic hardship was evident in almost 1 in 2 cancer survivors 1 year after diagnosis, especially AAs. Research should evaluate and address risk factors and their impact on survival and survivorship outcomes. Cancer 2015. © 2015 American Cancer Society.

    ABSTRACT: Purpose This study aims to evaluate the relationship between survivorship care planning (SCP) and survivorship care and health outcomes reported by long-term lung and colorectal cancer survivors. Methods Participants (n = 832) were diagnosed and enrolled during 2003-2005. In 2012, patient-reported outcomes (survivorship care and health outcomes) and two patient-reported SCP measures (receipt of written summary of cancer treatment and receipt of instructions on who to see for routine cancer follow-up) were collected. Analyses controlled for SCP predictors collected from medical records and an interview 1 year after diagnosis. Results One in four survivors reported receiving both SCP elements. Those receiving both were more certain which doctor was in charge (odds ratio (OR) 7.0; 95 % confidence intervals (95 % CI) 3.9-12.5), more likely to report follow-up checkup (OR 5.1; 95 % CI 3.3-8.0), and had an MRI/PET/CT scan in the past 2 years (OR 2.8; 95 % CI 1.7-4.7) compared to those receiving neither. Physician communication experiences were significantly more positive and having physical exams (OR 2.0; 95 % CI 1.2-3.4) and meeting exercise guidelines (OR 1.6; 95 % CI 1.004-2.4) more likely. Physical health (p = 0.012) and good-to-excellent self-perceived health status (OR 2.2; 95 % CI 1.3-3.9) were better for those receiving both elements. Conclusion SCP may lead to better cancer follow-up care, long-term physical health, and physician-patient communication experiences. Implications for Cancer Survivors The positive association between outcomes and SCP suggests that efforts to implement SCP should be fruitful.
