胰腺癌是一种极具侵犯性的肿瘤,其病死率几乎同于发病率,西方世界研究表明,胰腺癌所致死亡在所有肿瘤相关死亡中占第四位。平均生存时间仅为6个月,五年生存率仅3%～5%左右,通过辅助治疗,平均生存期或可提高至20个月左右,而胰腺癌恶性程度高,早期易发生转移,且早期诊断非常困难,仅有10%的患者在诊断时有手术条件。胰腺癌因其恶性程度高、早期症状隐匿、早期诊断率低而成为致死性极高的恶性肿瘤之一。研究有效的分
Pancreatic cancer is a highly aggressive tumor with a similar case-fatality rate. Western studies show that the death from pancreatic cancer ranks fourth for all cancer-related deaths. The average survival time is only 6 months, and the 5-year survival rate is only 3% ~ 5%. The mean survival time can be increased to about 20 months through adjuvant therapy. However, pancreatic cancer is highly malignant and is prone to metastasis in early stage. Early diagnosis is very difficult, only 10% of patients at the time of diagnosis of surgical conditions. Pancreatic cancer due to its high degree of malignancy, early symptoms of concealment, low early diagnosis and become one of the extremely lethal malignancy. Study effective points
