胰腺癌早期诊断困难,恶性程度高,进展迅速,预后极其不良,其病死率居恶性肿瘤的第四位。本文就小胰腺癌的诊断与治疗等有关问题综合介绍如下。一、小胰腺癌与早期胰腺癌小胰腺癌是指肿瘤最大径在2cm 以下者(T_1)。T_1可有淋巴结(N)转移,癌可浸润胰腺被膜(S)、胰后面组织(Rp)、系膜上静脉(SMV)及门静脉(PV),甚至可有血行转移,T_1故未必是早期癌。T_1为全部胰腺癌的3.3～5.0%。早期胰腺癌有两种解
The early diagnosis of pancreatic cancer is difficult, the degree of malignancy is high, the progress is rapid, and the prognosis is extremely poor. The mortality rate ranks fourth in malignant tumors. This article gives a comprehensive overview of the issues related to the diagnosis and treatment of small pancreatic cancer. First, small pancreatic cancer and early pancreatic cancer Small pancreatic cancer is the tumor whose maximum diameter is less than 2cm (T_1). T_1 may have lymph node (N) metastasis. The cancer may infiltrate the pancreas capsule (S), the posterior pancreatic tissue (Rp), the superior mesangial vein (SMV) and the portal vein (PV), and may even have blood metastasis. T_1 may not be early cancer. . T_1 is 3.3-5.0% of all pancreatic cancers. There are two solutions to early pancreatic cancer
