胰腺癌发病率近年来有不断增高的趋势。据统计,在美国胰腺癌是第二位最常见的胃肠道恶性肿瘤,居癌症死因的第四位。由于胰腺癌首发症状很不明确,特异性不强,胰腺又难于检查,病程早期即可转移扩散,早期诊断和有效的治疗一直是问题。确诊后最多只有20%的病人有肯定疗效的手术机会。尽管临床诊断、外科和麻醉技术以及全身支持疗法有了进展,但此病根治术后五年生存率也不过1—2%。
The incidence of pancreatic cancer has been increasing in recent years. According to statistics, pancreatic cancer is the second most common gastrointestinal cancer in the United States, ranking fourth in cancer death causes. Because the initial symptoms of pancreatic cancer are unclear and specificity is not strong, the pancreas is difficult to check, and the disease can spread and spread early in the course of the disease. Early diagnosis and effective treatment have always been problems. Only a maximum of 20% of patients have confirmed surgical outcomes after diagnosis. Although clinical diagnosis, surgical and anesthetic techniques, and systemic support therapy have advanced, the 5-year survival rate after radical resection of this disease is still only 1-2%.
