胰腺癌是消化系统肿瘤中最恶者,如不治疗一般于半年左右死亡。其发病有逐年增高的趋势,美国近40年～50年增加3倍,每年约25000人发病,占恶性肿瘤的第8位。日本近20年也增加3倍,死亡数仅次于胃癌、肺癌、肝癌,由占肿瘤的第7位上升到第4位。北京市1982年～1984年男性胰腺癌占恶性肿瘤的第8位,占恶性肿瘤死亡的第6位。女性占恶性肿瘤的第10位,占恶性肿瘤死亡的第6位。胰腺癌早期诊断困难,至今尚无唯一有效的诊断方法。日本1988年报告8年间胰腺癌8710例,其中直径小于2cm者313例,占3.6%。但在临床上所见到的几乎全部仍为中晚期癌。手术切除率低(10%～30%),我们在手术473例中切除43例,切除
Pancreatic cancer is the most devastating of digestive system tumors, and it usually dies in about half a year if it is not treated. The incidence of the disease has increased year by year. The United States has experienced a three-fold increase in the United States in the last 40 to 50 years, with approximately 25,000 cases per year, accounting for the eighth most common malignancy. Japan has also tripled in the past 20 years. The death toll is second only to gastric cancer, lung cancer, and liver cancer. It has risen from the 7th to the 4th. From 1982 to 1984 in Beijing, male pancreatic cancer accounted for the eighth place in malignant tumors and accounted for the sixth place in the death of malignant tumors. Women accounted for 10th for malignant tumors and 6th for malignant tumors. Early diagnosis of pancreatic cancer is difficult, and there is no single effective diagnostic method. In 1988, Japan reported 8,710 cases of pancreatic cancer over 8 years, of which 313 cases were less than 2cm in diameter, accounting for 3.6%. However, almost all clinically seen are still metaphase and advanced cancers. The surgical resection rate was low (10% to 30%). We removed 43 cases in 473 cases.
