Geographic distribution of hematopoietic cancers in the Nile delta of Egypt.

Background: Previous evidence indicated that incidence rates of non-Hodgkin's lymphoma (NHL) are high in Egypt although little is known about risk factors.

Materials And Methods: Using data from the population-based cancer registry of Gharbiah governorate in Egypt, we assessed the 1999-2005 incidence of hematopoietic cancers (HCs) based on the ICD-O3 by age- and sex-specific urban-rural distribution.

Results: NHL showed the highest incidence among all HCs (11.

Geographic patterns of cancer in the population-based registry of Egypt: Possible links to environmental exposures.

Background: We investigated the variation in cancer incidence in Gharbiah, Egypt to explore geographic differences in relation to demographic and environmental exposures.

Methods: Using data from the only population-based cancer registry of Gharbiah, we studied the 10 most common cancers in men and women over 4 years (1999-2002). Census data provided denominators and urban-rural definitions.

Urban-rural differences in breast cancer incidence in Egypt (1999-2006).

Objective: To describe urban-rural differences in breast cancer incidence in Gharbiah, Egypt and to investigate if these differences could be explained by known risk factors of breast cancer.

Methods: We used data from the population-based cancer registry of Gharbiah, Egypt to assess breast cancer incidence from 1999 through 2006. The Egyptian census provided data on district-specific population, age, and urban-rural classification.

Urban-rural differences of gynaecological malignancies in Egypt (1999-2002).

Objective: In previous studies, we have shown a three to four times higher urban incidence of breast cancer and estrogen receptor-positive breast cancers in the Gharbiah Province of Egypt. We investigated the urban-rural incidence differences of gynaecologic malignancies (uterine, ovarian and cervical cancers) to explore if they show the same trend that we found for breast cancer.

Design: Cancer registry-based incidence comparison.

Urban-rural differences in breast cancer incidence by hormone receptor status across 6 years in Egypt.

Breast cancer incidence is higher in developed countries with higher rates of estrogen receptor positive (ER+) tumors. ER+ tumors are caused by estrogenic exposures although known exposures explain approximately 50% of breast cancer risk. Unknown risk factors causing high breast cancer incidence exist that are estrogenic and development-related.

Patterns of hepatocellular carcinoma incidence in Egypt from a population-based cancer registry.

Aim: Hepatocellular carcinoma (HCC) is increasing worldwide, and is frequently attributed to rising rates of hepatitis C virus infection and interactions between viral and environmental risk factors. Because of Egypt's unique risk factor profile, we analyzed data from the Gharbiah Population-Based Cancer Registry for the period 1999-2003 to characterize demographic and geographic patterns of cases in this province.

Methods: We calculated age- and sex-specific and age- and sex-standardized HCC incidence rates for the eight districts in Gharbiah.
