Efforts to reduce global cancer disparities begin with an understanding of geographic patterns in cancer incidence, mortality, and prevalence. Using the GLOBOCAN (2002) and Cancer Incidence in Five Continents databases, we describe overall cancer incidence, mortality, and prevalence, age-adjusted temporal trends, and age-specific incidence patterns in selected geographic regions of the world. For the eight most common malignancies-cancers of lung, breast, colon and rectum, stomach, prostate, liver, cervix, and esophagus-the most important risk factors, cancer prevention and control measures are briefly reviewed. In 2002, an estimated 11 million new cancer cases and 7 million cancer deaths were reported worldwide; nearly 25 million persons were living with cancer. Among the eight most common cancers, global disparities in cancer incidence, mortality, and prevalence are evident, likely due to complex interactions of nonmodifiable (ie, genetic susceptibility and aging) and modifiable risk factors (ie, tobacco, infectious agents, diet, and physical activity). Indeed, when risk factors among populations are intertwined with differences in individual behaviors, cultural beliefs and practices, socioeconomic conditions, and health care systems, global cancer disparities are inevitable. For the eight most common cancers, priorities for reducing cancer disparities are discussed.

REATMENT OF HODGKIN DISease (HD) represents one of the major medical successes of the 20th century. Fifty years ago, the typical patient survived only a few years, 1 whereas the current 5-year relative survival rate is 85%. 2 In the United States alone, approximately 120000 survivors of HD 2 are at risk for the serious late sequelae of curative therapies, including the occurrence of new primary cancers. 3,4 Second malignant neoplasms are now the leading cause of death in longterm survivors of HD, 5,6 with breast cancer representing the most frequent solid tumor among women. 7,8 Estimates of breast cancer risk appear inversely related to age at treat-Author Affiliations are listed at the end of this article.

Since 2001, the World Health Organization classification for hematopoietic and lymphoid neoplasms has provided a framework for defining acute leukemia (AL) subtypes, although few populationbased studies have assessed incidence patterns and patient survival accordingly.We assessed AL incidence rates (

Testicular cancer survivors are at statistically significantly increased risk of solid tumors for at least 35 years after treatment. Young patients may experience high levels of risk as they reach older ages. The statistically significantly increased risk of malignant mesothelioma in testicular cancer survivors has, to our knowledge, not been observed previously in a cohort of patients treated with radiotherapy.

Significantly increased risks of second cancers were observed in all HD age groups. Although significantly elevated risks of stomach, female breast, and uterine cervix cancers persisted for 25 years, an apparent decrease in relative risk and AER of solid tumors at other sites is suggested.

Multivariable modeling demonstrates for the first time temporal changes in SC risk not evident in unadjusted analyses, and can facilitate the development of individualized risk assessment and the creation of screening strategies for early detection.

Breast cancer projections varied considerably by type of HL therapy, time since HL diagnosis, and age at end of follow-up. These estimates are applicable to HL survivors treated with regimens of the past and can be used to counsel such patients and plan management and preventive strategies. Projections should be used with caution, however, in patients treated with more recent approaches, including limited-field radiotherapy and/or ovary-sparing chemotherapy.

Background: Carcinomas of the major salivary glands (M-SGC) comprise a morphologically diverse group of rare tumors of largely unknown cause. To gain insight into etiology, we evaluated incidence of M-SGC using the WHO classification schema (WHO-2005
