Abstract

Abstract -Background: Cancer is the third leading cause of deaths in the West Bank and Gaza accounting for about 10% of total deaths. Despite its importance, little research has been devoted to characterization of incidence rates and geographic variations. This study compared the incidence rates and some risk factors of cancer among governorates of Northern West Bank and among types of locality (urban, rural, and refugee camps) for the period 2005-2008.Methods: Crude and age-adjusted incidence rates were calculated using cancer data obtained from the registry files of three hospitals in Northern West Bank. Negative binomial regression analysis was performed to compare incidence rate ratios (IRR) among governorates and types of locality while adjusting for age-group, sex and year of diagnosis. Fisher’s exact test was employed to test relationships among cross tabulated variables and test homogeneity of proportions.Results: The lowest overall incidence rate was found in the governorate of Jenin (age-adjusted rate of 45.0 cases per 100,000 over the 4-yr period). With Jenin taken as a reference, the governorate of Nablus had the highest IRR (3.30) with age-adjusted incidence of 148.1 cases per 100,000. Refugee camps had higher overall incidence rate than urban and rural areas (age adjusted rates of 169.0, 103.2, and 79.3 cases per 100,000 for refugee camps, urban, and rural areas, respectively). Geographical differences were found in the distribution of patients with regard to types of environmental pollution, dietary factors, smoking, alcohol consumption, types of stress, and chronic diseases but not in dietary habits and family history.Conclusions: In Northern West Bank, large differences were found among areas of residence (governorates and locality types) in incidence of cancer. Geographical differences in risk factors were also found which could explain part of the geographic differences observed in incidence rates.

الملخص

الخلفية: يعتبر السرطان ثالث أكبر مسبب للوفيات في الضفة الغربية و غزة بنسبة 10% من مجمل الوفيات. وبالرغم من هذه الأهمية للسرطان فإن البحث العلمي لا يزال غير كاف في مجال تحديد معدلات الإصابة واختلافاتها الجغرافية. و قد هدفت هذه الدراسة إلى مقارنة معدلات الإصابة بالسرطان والعوامل المسببة له بين المحافظات وأنواع التجمع السكاني (حضر، ريف، مخيم) في شمال الضفة الغربية في الفترة من 2005-2008.المنهج: تم حساب معدلات الإصابة من المعطيات التي تم جمعها من ملفات السرطان في ثلاثة مستشفيات في شمال الضفة الغربية. وقد  تمت مقارنة معدلات الإصابة باستخدام تحليل Negative Binomial Regression مع الأخذ بعين الاعتبار عوامل العمر والجنس و سنة التشخيص. كما تم استخدام exact test Fisher's لفحص ارتباط العوامل .النتائج: أظهرت النتائج أن أقل معدل للإصابة كان في محافظة جنين ( 45 حالة لكل 100000 شخص على مدى الأربع سنوات) بينما كان أعلى معدل إصابة في محافظة نابلس ( حوالي ثلاثة أضعاف معدل الإصابة في جنين بواقع 148.1حالة لكل 100000 شخص). كما كان معدل الإصابة في المخيمات أعلى من الحضر والريف (169و 103.2، و 79.3 حالة لكل 100000 شخص، على التوالي). كما أظهرت النتائج وجود اختلافات في توزيع المرضى بين المناطق الجغرافية (المحافظة و نوع التجمع) فيما يتعلق بكل من نوع التلوث البيئي، التدخين، شرب الكحول، القلق ، والأمراض المزمنة، بينما لم تلاحظ  فروق ذات دلالة إحصائية فيما يتعلق بالعادات الغذائية و تاريخ العائلة في الإصابة بالسرطان.
