BACKGROUND: Acute Lymphoblastic Leukemia (ALL) has a high survival rate, but cancer-related late effects in the early post-treatment years need documentation. Hospitalizations are an indicator of the burden of late effects. We identify rates and risk factors for hospitalization from five to ten years after diagnosis for childhood and adolescent ALL survivors compared to siblings and a matched population sample. METHODS: 176 ALL survivors were diagnosed at ≤22 years between 1998 and 2008 and treated at an Intermountain Healthcare facility...

BACKGROUND: Women with higher serum calcium may be more likely to be diagnosed and die of ovarian cancer. We evaluated that finding in a large, prospective cohort. METHODS: We conducted a nested case-control study using a population-based biobank from Norway. We compared 202 ovarian cancer cases and 202 controls, matched for age, date at blood draw, and county of residence, with respect to serum calcium and albumin, adjusted for anthropometric variables. We evaluated risks using the entire follow-up period as well as 2-15 years and 16-25 years ("early" and "late", respectively)...

BACKGROUND: Though the association between parental age at child's birth and the risk of childhood cancer has been previously investigated, the evidence to date is inconclusive and scarce for rarer cancer types. METHODS: Cancer cases (N=5,856) were selected from all children born from 1968 to 2014 and diagnosed from 1968 to 2015 in Denmark at less than 16 years of age listed in the nationwide Danish Cancer Registry. Cases were individually matched to controls (1:100) on sex and year of birth with a total of 585,594 controls randomly sampled from all live births in Denmark from the Danish Central Population Registry...

#4
Henry Jensen, Peter Vedsted
BACKGROUND: Implementation of standardised cancer patient pathways (CPPs) has provided faster diagnosis of cancer. Cancer survival has improved during the same time period. Concern has been raised that the faster diagnosis may have introduced lead-time bias by elongating the period from diagnosis to death. AIM: We aimed to analyse the possible effect of lead time on survival due to expedited cancer diagnosis after the implementation of national CPPs among incident cancer patients diagnosed through Danish primary care...

BACKGROUND: The experiences of patients with recurrent cancer are assumed to reflect those of patients with de novo stage IV disease; yet, little is truly known because most registries lack recurrence status. Using two databases with excellent recurrence and death information, we examined determinants of survival duration after recurrence of breast (BC), colorectal (CRC), and lung cancers (LC). METHODS: Recurrence status was abstracted from the medical records of patients who participated in the Cancer Care Outcomes Research and Surveillance study and who received care at two Cancer Research Network sites-the Colorado and Northwest regions of Kaiser Permanente...

BACKGROUND: Numerous studies have been conducted among farmers, but very few of them have involved large prospective cohorts, and few have included a significant proportion of women and farm workers. Our aim was to compare cancer incidence in the cohort (overall, by sex, and by work on farm, occupational status and pesticide use) within the general population. METHODS: More than 180,000 participants in the AGRICAN cohort were matched to cancer registries to identify cancer cases diagnosed from enrolment (2005-2007) to 31st December 2011...

BACKGROUND: Mammographic density is a known heritable risk factor for breast cancer, but reports how tumor characteristics and family history may modify this association are inconsistent. METHODS: Dense and total breast areas were assessed using Cumulus™ from pre-diagnostic mammograms for 820 invasive breast cancer cases and 820 matched controls nested within the French E3N cohort study. To allow comparisons across models, percent mammographic density (PMD) was standardized to the distribution of the controls...

Eva Morris, Tom Treasure
INTRODUCTION: An analysis of NHS data published in by Morris et al. in 2010 is widely used as evidence in support of liver metastasectomy for colorectal cancer and its wider application. Recent evidence concerning better overall survival for patients with metastatic colorectal cancer challenges the notional assumptions about what survival would be without metastasectomy. Earlier detection of metastases for local treatments has not resulted in a survival benefit. MATERIALS AND METHODS: The interpretation of its central graphical display is critically reviewed and the common the limitations of the analysis of registry data and resulting immortal time bias are explored...

BACKGROUND: Sedentary behaviour is a potential risk factor for colorectal cancer. We examined the association between sedentary work, based on body position, and colorectal cancer risk in Canadians. METHODS: A working body position category (a. sitting; b. standing and walking; c. sitting, standing, and walking; d. other) was assigned to occupations reported by 1991 Canadian Census respondents based on national occupational counselling guidelines. Adjusted hazard ratios (HRs) and 95% confidence intervals (CI) were estimated for cancers of the colon (overall, proximal, and distal) and rectum in men and women newly diagnosed from 1992 to 2010...

INTRODUCTION: The 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 METHODS: Data 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...

BACKGROUND: To investigate breast cancer prognosis (disease-free (DFS) and overall survival (OS)) among carriers of germline BRCA mutations (BRCAm) in Denmark. METHODS: We identified all women in Central and Northern Denmark diagnosed with breast cancer during 2004-2011. We retrieved information on germline BRCAm testing from Clinical Genetics departments and clinical/treatment characteristics from population-based medical registries. Follow-up for recurrence, new primary cancer, and mortality extended from 180days after diagnosis until 31/12/2012...

INTRODUCTION: The aims of this study were to identify counties in the United States (US) with high rates of lung cancer mortality, and to characterize the associated community-level factors while focusing on particulate-matter pollution. METHODS: We performed a descriptive analysis of lung cancer deaths in the US from 2004 through 2014. We categorized counties as "clustered" or "non-clustered" - based on whether or not they had high lung cancer mortality rates - using novel geospatial autocorrelation methods...

BACKGROUND: While previous studies have identified low socioeconomic status as a risk factor for metastatic disease in patients with high-grade osteosarcoma, the influence of socioeconomic status on overall survival remains unclear. The present study aims to investigate the relationship between survival and socioeconomic status in patients with high-grade conventional osteosarcoma. METHODS: The National Cancer Data Base (NCDB) was queried from 1998-2012 to identify all patients <40years of age with a diagnosis of high-grade conventional osteosarcoma...

BACKGROUND: Accumulating data has revealed a rapidly rising incidence of pancreatic cancer in Western countries, but convincing evidence from the East remains sparse. We aimed to quantify how the incidence and mortality rates of pancreatic malignancy changed over time in Taiwan, and to develop future projection for the next decade. METHODS: This nationwide population-based study analyzed the Taiwan National Cancer Registry and the National Cause of Death Registry to calculate the annual incidence and mortality rates of pancreatic malignancy from 1999 to 2012 in this country...

BACKGROUND: Population based cancer registration provides a critical role in disease surveillance in terms of incidence, survival, cancer cluster investigations and prevalence trends, and therefore high levels of completeness and timeliness are required. This study estimates completeness and variation between early and late registrations in the N. Ireland Cancer Registry (NICR) and assesses the implications for reporting cancer incidence and for registry-based research. METHODS: Two main approaches assessed completeness...

BACKGROUND: No previous Australian population-based studies have described or quantified the progression of colorectal cancer (CRC) to metastatic disease. We describe patterns of progression to metastatic disease for an Australian cohort diagnosed with localised or regional CRC. METHODS: All localised and regional CRC cases in the New South Wales Cancer Registry diagnosed during 2000-2007 were followed to December 2011 for subsequent metastases (identified by subsequent disease episode notifications) or CRC death...

BACKGROUND: To assess the impact of comorbidity, measured by the Charlson Comorbidity Index (CCI), on survival in breast, colorectal and lung cancer. METHODS: We identified 3455 breast cancer, 3336 colorectal cancer and 2654 lung cancer patients through the Hospital del Mar cancer registry. The prevalence of comorbidities according to the CCI was calculated. Kaplan-Meier curves and the log-rank test were used to compare survival curves for each cancer location. Cox regression was used to calculate survival hazard ratios and 1-, 3- and 5-year mortality rate ratios adjusted by age, sex, CCI, place of first consultation, stage, treatment and period of diagnosis...
