Although colorectal cancer is not a common cancer in Egypt, the age distribution of the disease shows that a high proportion occurs in children and adults under 40 years of age.
We reviewed the records of 1,608 colorectal cancer patients treated in 4 cancer hospitals in Egypt during a period of 3 to 10 years.
The hospitals in which about 85% of all colorectal cancer cases in Egypt were seen included Egypt's 2 major cancer centers, The National Cancer Institute (NCI) in Cairo and Tanta Cancer Center (TCC) in the mid-Nile Delta region, and 2 major university hospitals, Assiut University in South Egypt and Ain Shams University in Cairo.
Our review showed that patients younger than 40 years represented 35.6% of all patients in the 4 cancer hospitals, and that these rates were similar among the hospitals and for the years reviewed.
The male-to-female ratio increased from 1.0 to 1.7 for the age groups ranging from 0-9 and 30-39 years, and increased from 1.0 to 1.5 for the age groups ranging from 40-49 to over 60 years.
More than half of all the patients had rectal tumors, and about 90% of the cancers were adenocarcinomas ; 30.6% of patients younger than 40 years, compared with 13.8% of older patients, had mucin-producing tumors.
This study confirmed the occurrence of a high colorectal cancer rate in young Egyptians, and it opens the door to future epidemiologic studies to identify causes and risk factors of this disease pattern in Egypt.
