AIM:To study the epidemiology of gastric malignancies inJordan as a model for Middle East countries where suchdata is scarce.METHODS:Pertinent epidemiological and clinicopathologicaldata for 201 patients with gastric malignancy in north ofJordan between 1991 and 2001 were analyzed.RESULTS:Male:female ratio was 1.8:1.The mean agewas 61.2 years,and 8.5% of the patients were youngerthan 40 years of age.The overall age-adjusted incidencewas 5.82/100 000 population/year.The age specificincidence for males raised from 1.48 in those aged 30-39years to 72.4 in those aged 70-79 years.Adenocarcinomas,gastric lymphomas,malignant stromal tumors,andcarcinoids were found in 87.5%,8%,2.5%,and 2%respectively.There was an average of 10.1-month delaybetween the initial symptoms and the diagnosis.Only 82patients underwent“curative”gastrectomy.Amongadenocarcinoma groups,Lauren intestinal type was thecommonest(72.2%)and the distal third was the mostcommon localization(48.9%).The mean follow up forpatients with gastric adenocarcinoma was 25.1 mo(range1-132mo).The 5-year survival rates for stages Ⅰ(n=15),Ⅱ(n=41),Ⅲ(n=59),and Ⅳ(n=53) were 67.3%,41.3%,5.7%,and 0% respectively(P=0.0001).The overall 5 yearsurvival was 21.1%.CONCLUSION:Despite low inddence,some epidemiologicalfeatures of gastric cancer in Jordan mimic those of high-risk areas.Patients are detected and treated after arelatively long delay.No justification in favor of a possiblegastric cancer screening effort in Jordan is supported byour study;rather,the need of an earlier diagnosis andsubsequent better care.
AIM: To study the epidemiology of gastric malignancies in Jordan as a model for Middle East countries where such data is scarce. METHODS: Pertinent epidemiological and clinicopathological data for 201 patients with gastric malignancy in north of Jordan between 1991 and 2001 .RESULTS: Male: female ratio was 1.8: 1. The mean age was 61.2 years, and 8.5% of the patients were youngerthan 40 years of age. The overall age-adjusted incidencewas 5.82 / 100,000 population / year. The age specificincidence for males raised from 1.48 in those aged 30 -39years to 72.4 in those aged 70-79 years. Adenocarcinomas, gastric lymphomas, malignant stromal tumors, and carcinomas were found in 87.5%, 8%, 2.5%, and 2% respectively. There was an average of 10.1-month delay between the initial symptoms and the diagnosis. Ofly 82patients underwent “curative” gastrectomy. Amongadenocarcinoma groups, Lauren intestinal type was the comone (72.2%) and the distal third was the most common localization (48.9%). The mean follow up forpatie nts with gastric adenocarcinoma was 25.1 mo (range1-132mo) .The 5-year survival rates for stagesⅠ (n = 15), Ⅱ (n = 41), Ⅲ (n = 59) The overall incidence of gastric cancer in Jordan mimic those of high-risk areas. Patients are 67.3%, 41.3%, 5.7%, and 0% respectively detected and treated after are relatively long delay. No justification in favor of a possiblegastric cancer screening effort in Jordan is supported byour study; rather, the need of an earlier diagnosis andsubsequent better care.
