RESUMO

Pancreatic neuroendoerine tumors (PNET) is a complicated and heterogeneous group of neoplasia,and the incidence of PNET is growing rapidly recently.The current study on PNET lags behind what is known of other pancreatic tumors.Therefore,understanding of the molecular pathology is important for improving the early diagnosis,treatment and prognosis.With the development of molecular biology,there are already several potential targets proved to have application role in treatment of PNET.Here,the authors present the current knowledge about the molecular alterations of PNET.

RESUMO

Objective To screen the risk factors of liver metastasis in patients with postoperative colorectal cancer and to set up a mathematic model.Methods One hundred and sixty-eight patients received radical surgery were retrospectively analyzed.Logistics model regression was used to identify the risk factors and ROC test to complete a mathematic model.Results The 3 and 5-year incidence rate of liver metastasis was 25.0% and 33.3%,respectively.The risk factors of liver metastasis were lymph node metastasis (LNM),tumor invasive depth (TID),histological grading (G) and preoperative serum tumor markers (PSMs).The mathematic model was:logit (P) =-0.931 + 0.973 × LNM + 0.302 x TID + 0.637 x G + 0.042 x PSMs.Conclusion The risk factors of liver metastasis were LNM,TID,G and PSMs,and the mathematic model could be set up.
