Abstract
早期膵癌を発見するためのスクリーニング法を確立するため,1986年6月1日から1990年6月30日までの期間のprospective studyを行った。対象は,人間ドックを目的として来院した患者を主とする三朝分院の外来患者1,748名である。一次スクリーニング検査として,血清アミラーゼ,エラスターゼI,腹部超音波検査(US)を施行し155名の要精検者が得られ,要精検率は8.9%であった。155名の要精検者に,二次検査として,USの再精査,ERCP,腹部CTを施行した。その結果,早期膵癌患者1名,進行膵癌患者4名を発見し,膵癌発見率は0.29%と良好な成績であった。加えて,一次スクリーニングの検査項目を限定することによりcost-benifitを改善することができた。発見された膵癌患者の3名は60歳代であった。また,年代別要精検率は加齢とともに上昇した。1年以後にfollow-up検査を受けた患者の数は641名でfoilow-up率は36.7%であり,そのなかから膵癌は発見されなかった。60歳代のfollow-up率は40歳以上60歳未満のそれにくらべて有意の低値をとった。早期膵癌の見逃しを少なくするためには,今後,60歳代を中心とする患者のfollow-up率をさらに高めることが必要である。
Abstract Alternative
To find an effective mass screening method for detecting early pancreatic cancer among asymptomatic populations and patients with vague abdominal symptoms, a prospective study was attempted on 1748 patients who came to Medical Clinic of Misasa Branch Hospital, Okayama University Medical School mostly for a routine annual chek-up from June 1, 1986 through June 30, 1990. These patients underwent first-step screeing tests including serum amylase, elastase I and routine abdominal ultrasonography (US). Consequently 155 patients (8.9% of the total 1748 patients) showed abnormal findings and underwent secondstep tests including US, ERCP and computed tomography. Final diagnosis was early pancreatic cancer in one patient and advanced pancreatic cancer in four. Three of the 5 patients with pancreatic cancer were in their sixties. Detection rate of pancreatic cancer (0.29%) in this series was satisfactory as compared with the results of previous reports with US alone. The rate of second-step examination increased with age. Six hundred and forty-one patients (36.7% of the 1748 patients) underwent follow-up examinations more than one year after the previous test. No pancreatic cancer was detected in the 641 patients. The rate of follow-up examination in patients in their sixties was significantly lower than in those in their forties or fifties. It is important to improve the follow-up rate in patients in their sixties, because they are at a high risk for pancreatic cancer as suggested by the present study.
