BACKGROUND: Ewing family of tumors (EFT) represents the second-most common primary bone malignancy in children and adolescents. Approximately 25% of patients have radiographically detectable metastatic disease at presentation and experience poorer five-year survival, yet risk factors for metastatic disease at presentation are poorly characterized. We sought to study patient characteristics associated with metastatic disease upon presentation for patients with EFT. METHODS: We identified EFT cases in the Surveillance, Epidemiology, and End Results Program (SEER) registry from 2004 to 2012...

OBJECTIVE: Although overall childhood cancer survival has improved, survivors may still have an elevated risk for second primary neoplasm (SPN) and excess mortality. The aim of the current study was to estimate the risks for SPN and mortality in childhood cancer survivors in Israel as compared to the general population. METHODS: All children aged 0-19 diagnosed with primary neoplasm between 1980-2007 who survived at least 5 years following diagnosis were included in the study...

BACKGROUND: Oral and oropharyngeal cancers are among the most common cancers globally. This study aimed to assess the incidence and mortality trends of oral and oropharyngeal cancers in China between 2005 and 2013. METHODS: Estimates of national trends of oral and oropharyngeal cancers were based on the data from Chinese Cancer Registry Annual Reports. The crude incidence rates of oral and oropharyngeal cancers between 2015 and 2035 were evaluated. The age-standardized rate was based on the world standard population...

Christian Stock, Ute Mons, Hermann Brenner
BACKGROUND: Cancer incidence projections are of major interest for resource allocation in healthcare and medical research. Previous reports of cancer incidence projections have often been deterministic, i.e. lacking quantification of uncertainty. We project cancer incidence in Germany by applying an approach that allows for probabilistic interpretation of outcomes. MATERIAL AND METHODS: German cancer registry data from 1999 to 2013 are used to predict cancer incidence for 27 sites until the year 2030...

BACKGROUND: Smoking and alcohol consumption are potential risk factors for breast cancer (BC) and may modify the risk of radiotherapy-associated second primary cancer (SPC) occurrence and total mortality. We explored the joint effect of smoking, or alcohol drinking, and radiotherapy on the risk of SPC and overall mortality among BC survivals. METHODS: We conducted a cancer registry-based study of 10,676 BC cases (stage 0-III) with data on smoking and alcohol consumption at time of diagnosis and clinical and therapeutics characteristics...

BACKGROUND: The paucity of population-based research indicates that the application of intensive chemotherapy (ICT) among elderly acute myeloid leukemia (AML) patients, as well as their accrual to randomized controlled trials (RCTs) remains low for several decades. Therefore, a contemporary, comprehensive apprehension on patient-, disease-, and treatment-specific characteristics of elderly AML patients at the population level can inform treatment choices and facilitate increased patient accrual in upcoming RCTs...

BACKGROUND: Melanoma and renal-cell carcinoma (RCC) are known to be immunological neoplasms. Previous studies have shown increased risks in patients with melanoma of developing RCC and in those with RCC of developing melanoma. However, data regarding immunocompromised status in these patients are lacking. METHODS: We conducted a retrospective review of patients who had a diagnosis of melanoma and/or RCC. Using summary statistics, we calculated total person-years at risk for developing melanoma among patients with RCC and for developing RCC among patients with melanoma, and compared the results with the SEER data...

BACKGROUND: Barriers such as language and literacy might complicate the participation procedure for immigrants in screening programs. We investigated the delivery of a suitable stool sample for participation in the Danish colorectal cancer screening by immigration background. METHODS: National administrative registers were used to link results of faecal blood screening with immigrant status, age, sex, education, income, and marital status. Univariate and multivariate logistic regression models were used to estimate the odds of submitting an ineligible sample...

BACKGROUND: Individual patient data, e.g. from clinical trials, often need to be extrapolated or combined with additional evidence when assessing long-term impact in cost-effectiveness modeling studies. Different modeling methods can be used to represent the complex dynamics of clinical practice; the choice of which may impact cost-effectiveness outcomes. We compare the use of a previously designed cohort discrete-time state-transition model (DT-STM) with a discrete event simulation (DES) model...

BACKGROUND: Case-control studies remain an important study design for aetiologic research on cancer, particularly when cohorts are not available. In addition to the potential biases inherent in this design, conducting fieldwork in settings with weak health care and information systems for cancer, such as in sub Saharan Africa, confer additional challenges which we present here with the aim to share experience to guide future studies. METHODS: We undertook a hospital-based case-control study of squamous cell esophageal cancer at the Moi Teaching and Referral Hospital in Eldoret, West Kenya...

BACKGROUND: The rising incidence of colorectal cancer in sub-Saharan Africa may be partly caused by changing dietary patterns. We sought to establish the association between dietary patterns and colorectal cancer in Zimbabwe. METHODS: One hundred colorectal cancer cases and 200 community-based controls were recruited. Data were collected using a food frequency questionnaire, and dietary patterns derived by principal component analysis. Generalised linear and logistic regression models were used to assess the associations between dietary patterns, participant characteristics and colorectal cancer...

BACKGROUND: Epidermal Growth Factor Receptor (EGFR) mutation testing is recommended for patients with non-squamous non-small cell lung cancer (NSCLC) but not all eligible patients get tested, which may bias the mutation prevalence estimated. This study aims to examine trends in the uptake of EGFR mutation testing in patients with non-squamous NSCLC in New Zealand; to develop a composite metric that quantifies the influences of demographic and clinico-pathological factors on the testing uptake; and to estimate the prevalence of EGFR mutation if all patients were tested...
