Gender and Race/Ethnicity Affect the Cost-Effectiveness of Colorectal Cancer Screening. METHODS

California Cancer Registry collects information on every case of diagnosed or treated in California. Standard data are abstracted from the medical record for each case by trained tumor registrars, according to Cancer Reporting in California: Volume 1, Abstracting and Coding Procedures for Hospitals and computerized using C/NET, a software package developed for tumor registries. C/NET meets all reporting requirements of the Surveillance, Epidemiology and End Results (SEER) program, the American College of Surgeons and the California Cancer Reporting System. The quality of data is maintained through periodic training programs for hospital registrars and field abstractors, reabstraction of a 10% sample of case finding, and computer edits for completion and consistency. Additional audits of case finding and data abstraction are conducted by the California Department of Health Services. Completeness of coverage is Completeness is estimated to be higher than 99% annually from 1988 through 1998.

Recorded data includes demographic information [age, gender, race/ethnicity (white, black, Latino or Asian)], pathology, site of disease, stage of disease, treatment during the first four months and survival status. Tumor site and histology are coded according to criteria specified by the World Health Organization in International Classification of Diseases for Oncology (ICD-O). All cases included in this paper were primary invasive adenocarcinomas of the colon or rectum, and >99% were confirmed histologically. Tumors from the cecum to the transverse colon were considered ascending and transverse colon tumors (right-sided cancers), while tumors from the splenic flexure to the rectum were considered left-sided cancers. Invasive cancers localized to the colon or rectum (node-negative without metastases) were considered localized. Node-positive or metastatic cancers were considered nonlocalized. Average annual age-specific colorectal cancer incidence rates for each race or ethnicity were calculated by dividing the age-specific number of incident colorectal cancers cases from 1988-1995 in California by the age-specific population over the same period.

SEER data for colorectal cancer survival were obtained from the SEER Cancer Incidence Public-Use Database 1992-1998. Age-specific colorectal cancer survival tables were available for white and black men and women. Age-specific colorectal cancer survival tables of “other than white” were used for Latino and Asian men and women. When you need your medication buy celecoxib 200

Life expectancy tables for Californians from 1989-1991 were obtained from the National Center for Health Statistics at the Centers for Disease Control and Prevention. Life expectancy tables were available for white and black men and women. Life expectancy tables of “other than white” were used for Latino and Asian men and women.
