摘要Melanoma,the most aggressive form of skin cancer,remains a significant clinical challenge due to the high metastatic potential and drug resistance.This review explores the pivotal roles of angiogenesis and vasculogenic mimicry in melanoma progression and treatment resistance.Angiogenesis,driven primarily by VEGF/VEGFR signaling,is critical for tumor sustenance but is often insufficient under hypoxic conditions,prompting melanoma cells to adapt by forming vascular-like structures(i.e.,vasculogenic mimicry).These structures enable melanoma cells to mimic endothelial functions and are linked to increased metastasis and poor prognosis.Molecular drivers,including VE-cadherin,EphA2,and hypoxia-inducible factors,have been identified as key regulators of these processes.Current anti-angiogenic agents have limited efficacy in advanced/metastatic melanoma due to tumor plasticity and the interplay between angiogenesis and vasculogenic mimicry.The review highlights the need for therapeutic strategies targeting both mechanisms,emphasizing the importance of combination treatments to overcome resistance.Future research should aim to elucidate the molecular underpinnings of angiogenesis and vasculogenic mimicry to improve melanoma management and patient outcomes.
