Advancement in researches of mechanism of nervous invasion of pancreatic cancer and its countermeasures / 中华肝胆外科杂志

ABSTRACT

Perineural invasion(PNl) is regarded as a factor associated with local recurrence and an important prognostic factor in pancreatic cancer.Little is known about the mechanism of PNI in Pancreatic cancer.This review summarizes the role of innervation, clinicopathologic factors, lymhatic vessels, vascularity, cytokines, adhesion molecules, some immunoglobulin superfamily members and mucin in PNI.Because PNI is often followed by poor survival.An ear-lier diagnosis can improve pancreatic cancer prognosis.IPEUS,CT scan and immunostaining CK-19, K-ras gene a-nalysis can be used to diagnose perineural invasion pre-, in-tra-or postoperatively.A wide surgical exeresis with an enough lymph nodes clearance together with surrounding connective and nervous tissue can get a better long term survival rate.
