Management of Lower Limb Soft Tissue Sarcomas with Major Neurovascular Involvement: Current and Future Perspectives

Abstract

Lower limb soft tissue sarcomas are a group of rare mesenchymal tumours that may grow in close anatomical proximity to major neurovascular structures, leading to significant oncological and surgical challenges for treating physicians. This article reviews the current literature on the multidisciplinary approach of treating lower limb soft tissue sarcomas with neurovascular involvement and describes the increasing shift towards limb-sparing surgeries, with an emphasis on improved functional outcomes based on a multimodal treatment approach. In addition to identifying the histological subtype of the tumour, classifying the neurovascular involvement precisely is key in planning the appropriate treatment. Existing classification systems for both vascular and neural involvement are discussed, and a combined neurovascular classification is proposed together with a general treatment algorithm.
