Objective: This study examined subsite-specific colorectal cancer incidence rates and stage distributions for Asians and Pacific Islanders (API) and compared the API data with data for Whites and African Americans.

Methods: Data included 336,798 invasive colorectal cancer incident cases for 1995 to 1999 from 23 population-based central cancer registries, representing about two thirds of API population in the United States. Age-adjusted rates, using the 2000 U.

Background: Central cancer registries provide data to monitor incidence rates of cutaneous melanoma.

Objective: The aim of this study was to assess the completeness of melanoma reporting in the United States.

Methods: Data provided by central cancer registries were used to calculate age-adjusted, average annual incidence rates and were compared by time period (1992-1994, 1995-1997), stage, and program (Surveillance Epidemiology and End Results [SEER] and National Program of Cancer Registries [NPCR]).

Reliable information about comparative cancer incidence in the Middle East has been lacking. The Middle East Cancer Consortium (MECC) has formed a network of population-based registries with standardized basic data. Here the age-adjusted cancer incidences are compared for four populations: Israeli Jews, Israeli non-Jews, Jordanians and the US Surveillance Epidemiology and End Results (SEER) population, for the years 1996-1997 (Israel) and 1996-1998 (other populations).

Purpose: To examine cancer incidence patterns among adolescents and young adults in the United States.

Methods: Cancer incidence data from 26 population-based central cancer registries for 1992-1997 were used. Individual cancers were grouped into specific diagnostic groups and subgroups using an integrated classification scheme.
