胰腺癌的发病率有逐年增高的趋势,其恶性度高,进展迅速,自然病程一般不超过半年。目前胰腺癌的治疗效果是不满意的,手术切除率低,五年生存率亦为消化道癌最低者。这主要是由于胰腺癌诊断上的困难所致。为了提高疗效,国内外学者正在努力发现早期小胰癌。胰腺癌的诊断方法很多,但至今还没有象肝癌那样有效的普查方法。实验室检查多无确诊意义,各种物理检查也有其局限性。如何提高胰腺癌的早期诊断,仍是临床研究的课题。目前重要的是临床医生对胰腺癌要有高度的警惕性。胰腺及壶腹周围癌的早期临床症状虽然多是非特异性的,但认识和诊断胰腺癌仍必须首先根据它所表现的症状和体征,并进一步做全面检查。根据我们多年临床经验应注意以 The incidence of pancreatic cancer has increased year by year, with a high degree of malignancy and rapid progress. The natural course of disease generally does not exceed six months. At present, the therapeutic effect of pancreatic cancer is not satisfactory, and the surgical resection rate is low. The five-year survival rate is also the lowest in gastrointestinal cancer. This is mainly due to the difficulty in the diagnosis of pancreatic cancer. In order to improve curative effect, scholars at home and abroad are trying hard to find early small pancreatic cancer. There are many methods for diagnosing pancreatic cancer, but there is no effective screening method for liver cancer yet. Many laboratory tests have no confirmed significance, and various physical tests also have their limitations. How to improve the early diagnosis of pancreatic cancer is still the subject of clinical research. It is important for clinicians to have a high degree of vigilance against pancreatic cancer. Although most of the early clinical symptoms of pancreatic and periampullary cancer are non-specific, understanding and diagnosing pancreatic cancer must first be based on the symptoms and signs it exhibits, and further examination should be performed. According to our many years of clinical experience, we should pay attention to
