BACKGROUNDBladder cancer is notable for a striking heterogeneity of disease‐specific risks. Among the approximately 75% of incident cases found to be superficial to the muscularis propria at the time of presentation (non–muscle‐invasive bladder cancer), the risk of progression to the lethal phenotype of muscle‐invasive disease is strongly associated with stage and grade of disease. Given the suggestion...
BACKGROUNDThe American Cancer Society (ACS), the Centers for Disease Control and Prevention (CDC), the National Cancer Institute (NCI), and the North American Association of Central Cancer Registries (NAACCR) collaborate annually to provide updates on cancer incidence and death rates and trends in these outcomes for the United States. This year's report includes the prevalence of comorbidity at the...
BACKGROUNDMyelodysplastic syndromes (MDS) appear to be underreported to cancer registries, with important implications for cancer and transfusion support service planning and delivery. Two population‐based databases were linked to estimate MDS incidence more accurately.
METHODSData from the statewide Victorian Cancer Registry (VCR) and Victorian Admitted Episode Dataset (VAED, capturing all inpatient...
BACKGROUNDIn American Indians (AIs), cancer is a leading cause of mortality, yet their disease burden is not fully understood due to unaddressed racial misclassification in cancer registries. This study describes cancer trends among AIs in Michigan, focusing on breast cancer, in a linked data set of Indian Health Service (IHS), tribal, and state cancer registry data adjusted for misclassification...
BACKGROUNDThe 1996 National Cancer Institute Working Group (NCI‐WG 96) guidelines classified disease in individuals who had a B‐cell clone with chronic lymphocytic leukemia (CLL) immunophenotype as CLL if their absolute lymphocyte count was ≥5 × 109/L. The 2008 International Workshop on CLL guidelines (IWCLL 2008) classified disease as CLL if the absolute B‐cell count was ≥5 × 109/L or as monoclonal...
BACKGROUNDInvasive cervical cancer is thought to decline in women over 65 years old, the age at which cessation of routine cervical cancer screening is recommended. However, national cervical cancer incidence rates do not account for the high prevalence of hysterectomy in the United States.
METHODSUsing estimates of hysterectomy prevalence from the Behavioral Risk Factor Surveillance System (BRFSS),...
BACKGROUNDThe relationship between socioeconomic status and cancer incidence in the United States has not traditionally been a focus of population‐based cancer surveillance systems.
METHODSNearly 3 million tumors diagnosed between 2005 and 2009 from 16 states plus Los Angeles were assigned into 1 of 4 groupings based on the poverty rate of the residential census tract at time of diagnosis. The sex‐specific...
BACKGROUNDAlthough rising incidence rates of testicular germ cell tumors have been well documented in white men, relatively little is known about rates in men of Hispanic origin. In the current study, the authors compared germ cell tumor trends between men of Hispanic and non‐Hispanic origin as a function of age at diagnosis.
METHODSTrends in testicular germ cell tumor incidence among white men were...
BACKGROUNDIdeally, screening detects cancer at a more curable stage and, as a result, decreases the rate of subsequent diagnosis at a late stage. Although it is suggested that some cancer screening tests have led to substantial increases in early‐stage incidence with only marginal reductions in late‐stage incidence (eg mammography), the association between temporal trends in colorectal cancer screening...
BACKGROUNDThe Childhood Cancer Research Network (CCRN) was established within the Children's Oncology Group (COG) in July 2008 to provide a centralized pediatric cancer research registry for investigators conducting approved etiologic and survivorship studies. The authors conducted an ecological analysis to characterize CCRN catchment at >200 COG institutions by demographic characteristics, diagnosis,...
BACKGROUNDCurrently, little information is available on childhood cancer incidence rates in Eastern Asia. The objective of this study was to report the first population‐based cancer surveillance of children and adolescents in Taiwan.
METHODSData from the Taiwan Cancer Registry were examined for cancer frequencies and incidence rates among individuals ages birth to 19 years from 1995 to 2009. Types...
BACKGROUND
During the Vietnam War, US and allied military sprayed approximately 77 million liters of tactical herbicides including Agent Orange, contaminated with 2,3,7,8‐tetrachlorodibenzo‐p‐dioxin. To the authors' knowledge, few studies to date have examined the association between Agent Orange exposure and cancer incidence among Korean veterans who were exposed to Agent Orange during the Vietnam...
