Operation and tumor metastasis / 国际肿瘤学杂志

Prior to the formation of new metastases,a large number of cancer cells released from the primary tumor enter the dormancy period.Once the dorruancy is broken,tumor cells will recover the capability of proliferation.In recent years,various hypotheses and mechanisms of tumor metastasis have been studied.Primary tumor resection is considered to be an important factor to break tumor dormancy state.It is recognized as an important reason to promote tumor metastasis.The improvement of surgical technique and further study on the mechanism of dormancy may provide new ideas for the treatment of metastatic tumor.

Research progress of Dickkopf-1 related tumor metastasis / 国际肿瘤学杂志

As a secreted glycoprotein,Dickkopf-1 (DKK1) is closely related to tumor metastasis,and it is highly or lowly expressed in tumor.The high expression of DKK1 promotes the metastasis of a variety of malignant tumors including liver cancer,gastric cancer,non-small cell lung cancer and breast cancer.Recent studies have found that DKK1 is inextricably bound up with the latent metastasis of tumor.
