Abstract

Background Prostate cancer (CaP) is the most commonly diagnosed non cutaneous cancer and the third most common cause of death from cancer in males. PSA is considered the most useful tumor marker currently available for diagnosis and management of the CaP. The digital rectal examination is still the basis in the suspicion of CaP in males with normal or minimally high PSA levels. Aim the aim of the study is to evaluate the effectiveness of PSA versus digital rectal examination (DRE) in identifying cases of prostate cancer among men presenting with symptoms of bladder outflow obstruction. Patients and methods A cross sectional study was conducted at Azadi Teaching Hospital in Dohuk on 400 patients with bladder outflow obstruction above 50 years were selected between January 2005 and October 2007. DRE and serum PSA done for all patients and prostate biopsy for abnormal results. Results The mean age 69.63±8.3 years. All cases of documented prostate cancer with positive DRE had PSA ≥ 4 ng/ml. Conclusions In conclusion, DRE is still the basic step in the suspecting prostate cancer. Combination of DRE and PSA has the highest detection rate for CaP than each alone.

خلفية البحث: سرطان الموثة هو اكثر الامراض الخبيثة المشخصة شيوعا (بعد استبعاد الأورام الجلدية) وتعتبر السبب الثالث للوفاة من الاورام عند الذكور. ان مولد المضاد النوعي للموثة (PSA) هو الاكثر اعتمادا للاستخدام في تشخيص المرضى المصابين بمرض الموثة الخبيث. فحص الموثة عن طريق المستقيم (DRE) وارتفاع مستوى مولد المضاد النوعي للموثة هي الاشارات الاولية المعتمدة لتشخيص ورم الموثة الخبيث.الهدف: الغرض من الدراسة هو لتقييم مدى فعاليةPSA مع فحص الموثة عن طريق المستقيم فى تشخيص مرض سرطان الموثة لدى المرضى المصابين بأعراض انسداد المجرى البولي. المرضى و طرق البحث: اجري البحث فى مستشفى أزادي التعليمى العام على 400 مريض المصابين بأعراض انسداد المجرى البولي والذين أعمارهم تتجاوز 50 سنة خلال الفترة ما بين كانون الأول 2005- تشرين الثاني 2007, وأجري فحصPSA وفحص الموثة عن طريق المستقيم لكل المرضى مع أخذ خزعة من الموثة للنتائج الغير الطبيعية.النتائج: معدل العمر للمرضى 69.63 سنة, كل المرضى المصابين بسرطان الموثة والذين لديهم عقدة فى الموثة عن طريق فحص المستقيم ثبت ان لديهم PSA أكثر من .4 ng/mlالأستنباطات: فحص الموثة عن طريق المستقيم لا يزال الخطوة الاساسية لتشخيص سرطان الموثة. فحص الموثة عن طريق المستقيم مع PSA مع أخذ أو عدم أخذ خزعة من الموثة تعتبر الطريقة المثلى لتشخيص سرطان الموثة.

Abstract

Background and objective: To determine the difference of acquired skills of how to perform Digital Rectal Examination and Urethral Catheterization, by medical students of two groups. Group (A) large group (traditional teaching group) and Group (B) small teaching groupMethods: A questionnaire containing information related to digital rectal examination (DRE) and urethral catheterization was given to all year six medical students at College of Medicine, University of Sulaimanyia , in June 2004 and 2007, just before their fina examination. The questionnaire focused on the important points in relation to ways of teaching.Results: Responses to all given questions in the questionnaire from the two groups were different, 54% of students from traditional teaching group responded as oppose to 53% from small group . Up to 93% of traditional teaching group student were taught how to perform Digital Rectal Examination, while approximately 80% of students from small teaching group have been taught to do DRE. Only 23% of those among traditional teaching group have done more than 3 DRE, while that of small teaching group was only 8%. In both groups, their findings were uncommonly checked by senior doctor. In both groups nearly 80% of the students had never felt a clinically malignant prostate and nearly the same for rectal tumor. Students from traditional teaching group, who did Digital Rectal Examination, 22% of them were not sure about their ability to give an opinion based on their clinical findings, while 33% of the small teaching groups were unable to give opinion. Nearly 73% in traditional reaching group have been taught how to perform male urethral catheterization, while that of small teaching group was 78%. In traditional teaching group, only 23% have performed 2 and less male urethral catheterization on qualification while 44% in small teaching group. 39% of small teaching group were not confident at all to do male urethral catheterization, while that of traditional teaching group was 27% only.Conclusion: There was obvious similarity between the two groups regarding the lack of basic skill in conducting DRE, urethral catheterization. This was probably due lack of objectives in the teaching curriculum.
