黑色素瘤不同器官转移机制的研究进展及展望OA

Melanoma is a highly aggressive skin tumor and the leading cause of skin cancer related death.It can spread from a relatively small primary tumor and metastasize to multiple sites,including lymph nodes,liver,lung,brain,and bone,among others.Metastatic melanoma occurs when tumor cells separate from the primary lesion,migrate with circulating blood flow,penetrate the extracellular matrix and invade blood vessels and/or lymphatics,and form tumors at a distance.The ability of melanoma to metastasize is one of the key factors in the treatment and prognosis of this disease.In recent years,important progress has been made in the study of the mechanism of malignant melanoma metastasis.For instance,activation of signaling pathways promotes the formation of vasculogenic mimicry,thereby inducing the growth of metastatic foci,while genetic mutations drive metabolic adaptation and reprogramming of the tumor microenvironment.This review aims to summarize the relevant literature in recent years and explore the key mechanisms of malignant melanoma metastasis to different organs,including gene mutation,epithelial-mesenchymal transition,tumor microenvironment,and signal transduction pathways.By gaining insight into these mechanisms,we can better understand the metastatic process of malignant melanoma and provide a theoretical basis for the development of new therapeutic strategies.
