Despite its clinical resemblance to cancer, molecular drivers of its aggressiveness remain poorly defined. Recent studies highlight perilesional\u00a0angiogenesis as pivotal for lesion invasiveness, mediated by VEGF-driven pathological vascularization. VEGF not only fuels parasitic proliferation by creating nutrient-rich microenvironments but also engages crosstalk with host-parasite interactions, including immune evasion by Echinococcus multilocularis, germinal layer hyperplasia, and periparasitic inflammation.Targeting the HIF-1\u03b1\/VEGF\/VEGFR2 axis emerges as a promising therapeutic strategy. Mechanistically, VEGF\/VEGFR2 blockade may simultaneously disrupt angiogenesis-dependent parasitic expansion and survival pathways. Preclinical evidence shows that inhibiting HIF-1\u03b1 (VEGF\u2019s upstream regulator) suppresses metacestode proliferation and tissue invasion by starving lesions of vascular support while modulating immune-inflammatory responses. This dual action addresses both parasitic resource acquisition and host defence subversion.This review synthesizes molecular insights into HIF-1\u03b1\/VEGF-mediated pathogenesis with clinical observations, proposing anti-angiogenic therapy as a rational adjunct to current treatments. By delineating VEGF\u2019s role in sustaining parasitic metabolic demands and immune regulation, we underscore the translational potential of pathway-specific inhibitors. Such approaches could mitigate limitations of conventional therapies (e.g., benzimidazoles), particularly for advanced-stage AE with microvascular proliferation. Systematic analysis of angiogenesis signalling networks advances our understanding of AE\u2019s \u201cparasitic cancer\u201d paradigm while guiding development of targeted interventions to improve patient outcomes.<\/jats:p>","DOI":"10.3389\/fonc.2025.1553125","type":"journal-article","created":{"date-parts":[[2025,4,8]],"date-time":"2025-04-08T04:32:23Z","timestamp":1744086743000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":3,"title":["Progress
