TL;DR: The sharp decrease in incidence from 2002 to 2003 that occurred in women 50 to 69 years old who predominantly, but not exclusively, had ER+ tumors may reflect the early benefit of the reduced use of hormone replacement therapy.
Abstract: A recent abstract presented in a breast cancer symposium attributed the sharp decrease in female breast cancer incidence rates from 2002 to 2003 in the Surveillance, Epidemiology, and End Results (SEER) cancer registries of the United States to the reduced use of hormone replacement therapy since July 2002. However, this hypothesis does not explain the decrease that began in 1999 in the age-standardized incidence rate of invasive breast cancer in the nine oldest SEER cancer registry areas, although the trend through 2003 was not statistically significant. In this paper, we examine temporal trends in invasive and in situ female breast cancer by age, stage, tumor size, and estrogen receptor/progestin receptor (ER/PR) status in the nine oldest SEER cancer registry areas and consider the implication of these trends in relation to risk factors and screening. We performed a joinpoint regression analysis to fit a series of joined straight lines to the trends in age-adjusted rates and described the resultant trends (slope) by annual percentage change (two-sided, P < 0.05). A plot of the age-specific rates of invasive breast cancer shows a decrease in all 5-year age groups from 45 years and above between 1999 and 2003 and sharp decreases largely confined to ER+ tumors in age groups from 50 to 69 years between 2002 and 2003. In joinpoint analyses by tumor size and stage, incidence rates decreased for small tumors (less than or equal to 2 cm) by 4.1% (95% confidence interval [CI], 0.2% to 7.8%) per year from 2000 through 2003 and for localized disease by 3.1% (95% CI, 1.2% to 5.0%) per year from 1999 through 2003. No decrease in incidence was observed for larger tumors or advanced-stage disease during the corresponding periods. Rates for in situ disease were stable from 2000 through 2003 after increasing rapidly since 1981. Two distinct patterns are observed in breast cancer trends. The downturn in incidence rates in all age groups above 45 years suggests a period effect that is consistent with saturation in screening mammography. The sharp decrease in incidence from 2002 to 2003 that occurred in women 50 to 69 years old who predominantly, but not exclusively, had ER+ tumors may reflect the early benefit of the reduced use of hormone replacement therapy.

TL;DR: The American Cancer Society has updated historical cancer mortality statistics using the 2000 U.S. standard population for the age adjustment of death rates to reflect the new standard.
Abstract: BACKGROUND
Progress against cancer can be examined by analyzing long-term trends in cancer incidence and mortality. The recent directive from the U.S. Department of Health and Human Services to adopt the 2000 U.S. standard population for the age adjustment of death rates prompted the American Cancer Society to update historical cancer mortality statistics using the new standard.
METHODS
Mortality data were abstracted by race, gender, year, and age at death for 1930 through 1959 from annual volumes of Vital Statistics of the United States. For 1960 through 1998, these data were obtained from data tapes provided by the National Center for Health Statistics. Two U.S. standard million populations (1970 and 2000) were used to calculate age-adjusted rates. Average annual percent change was estimated for each decade by site, gender, and age, and the statistical significance of the change was assessed at p < 0.05.
RESULTS
After long-term increases or mostly level trends that date from the 1930s for some sites, death rates for cancers of the lung (in males), prostate, female breast, colon-rectum, pancreas, leukemia, and ovary were decreasing in the 1990s. Liver cancer death rates were increasing in the 1990s. Throughout the study period, death rates for female lung cancer increased, while death rates for stomach and uterine cancers declined.
CONCLUSIONS
The trends of decreasing cancer death rates for the leading cancer sites in the 1990s are encouraging. However, surveillance researchers must continue to monitor these declines to assess whether the progress seen in this decade persists. Efforts also must be made to study the sites with increasing trends and identify potential underlying causes. Cancer 2003;97(12 Suppl):3133–3275. Published 2003 by the American Cancer Society.

TL;DR: The Asia Pacific Working Group on Colorectal Cancer and international experts launch consensus recommendations aiming to improve the awareness of healthcare providers of the changing epidemiology and screening tests available, as well as reviewing the literature and regional data.
Abstract: Colorectal cancer (CRC) is rapidly increasing in Asia, but screening guidelines are lacking. Through reviewing the literature and regional data, and using the modified Delphi process, the Asia Pacific Working Group on Colorectal Cancer and international experts launch consensus recommendations aiming to improve the awareness of healthcare providers of the changing epidemiology and screening tests available. The incidence, anatomical distribution and mortality of CRC among Asian populations are not different compared with Western countries. There is a trend of proximal migration of colonic polyps. Flat or depressed lesions are not uncommon. Screening for CRC should be started at the age of 50 years. Male gender, smoking, obesity and family history are risk factors for colorectal neoplasia. Faecal occult blood test (FOBT, guaiac-based and immunochemical tests), flexible sigmoidoscopy and colonoscopy are recommended for CRC screening. Double-contrast barium enema and CT colonography are not preferred. In resource-limited countries, FOBT is the first choice for CRC screening. Polyps 5-9 mm in diameter should be removed endoscopically and, following a negative colonoscopy, a repeat examination should be performed in 10 years. Screening for CRC should be a national health priority in most Asian countries. Studies on barriers to CRC screening, education for the public and engagement of primary care physicians should be undertaken. There is no consensus on whether nurses should be trained to perform endoscopic procedures for screening of colorectal neoplasia.

TL;DR: Most established risk factors were more strongly associated with nonserous carcinomas, which demonstrate challenges for risk prediction of serous cancers, the most fatal subtype.
