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.

Abstract. Qena is the southernmost governorate of Egypt included in the Epidemiology 1, 2, 3 national study. A probability sample selected 17,822 individuals from 2,950 households in 34 ezbas and 10 villages from a total rural target population of 1,731,252 (based on the most recent 1986 census of the population by the Egyptian Central Agency for Public Mobilization And Statistics). Parasitologic examination of urine and stool were made for Schistosoma haematobium and S. mansoni, respectively, and physical and ultrasound examinations were made on a 20% subsample. The overall estimated prevalence of S. haematobium was 4.8 Ϯ 0.7% (ϮSE) and geometric mean egg count (GMEC) was 7.0 ova per 10 ml of urine. Considerable variation in prevalence was observed between the villages and ezbas, ranging from 0.0% to 20%, with the smaller ezbas having a slightly higher overall prevalence. The age-and sex-specific patterns of S. haematobium showed typical peak prevalence in early adolescence, with males having a higher prevalence than females. A history of hematuria was associated with current infection (odds ratio ϭ 3.6, 95% confidence interval ϭ 2.32-5.63). Hepatomegaly and splenomegaly determined by physical examination present in 7.9% and 3.0%, respectively. Ultrasonography-determined hepatomegaly of the left liver lobe was found in 10.1%. Ultrasonography-detected hepatomegaly in both the left and right lobes increased in prevalence from approximately 5% in children to 15-20% in adults. The prevalence of ultrasonography-detected splenomegaly increased slightly with age. Grade III periportal fibrosis was detected in only 2 individuals in the sample. Bladder wall lesions and obstructive uropathy were also very infrequent. Other associations with these measures are given. Most villages and ezbas had an S. mansoni prevalence of less than 1%. The exception was Nag'a El-Sheikh Hamad, where the prevalence was 10.3 Ϯ 0.5% (GMEC ϭ 57.4 Ϯ 2.6). Two other communities also had a prevalence Ͼ1% (Ezbet Sarhan and Kom Heitin).The Qena governorate, in Upper Egypt, is best known as the location of some of Egypt's most famous Pharaonic temples, such as Karnek and Dendera, and its Pharaonic tombs, the Valley of the Kings, in Tebes on the west bank of Luxor. The governorate is located about 535-650 km south of Cairo on the Nile River, as shown on the map in Figure 1 of the report in this supplement by El-Khoby and others. 1 Qena is bordered on the north by Sohag and on the south by the Aswan governorate. The Nile valley is at its narrowest in Egypt here and the arable land, a green strip only 1 or 2 km on either side of the river, is bordered by barren desert on both sides. The governorate is perennially irrigated throughout by principal main and distributory canals (Egyptian Ministry of Irrigation, unpublished data). The major crop is sugar cane, which requires large quantities of water drawn by pumps from surrounding canals. Other food crops are grown in small plots adjacent to the villages and are irrigated manually. In this region where the...
