摘要
Surgical resection remains a mainstay in the treatment of malignant solid tumors.However,the use of neoadjuvant treatments,including chemotherapy,radiotherapy,phototherapy,and immunotherapy,either alone or in combination,as a preoperative intervention regimen,have attracted increasing attention in the last decade.Early randomized,controlled trials in some tumor settings have not shown a significant difference between the survival rates in long-term neoadjuvant therapy and adjuvant therapy.However,this has not hampered the increasing use of neoadjuvant treatments in clinical practice,due to its evident downstaging of primary tumors to delineate the surgical margin,tailoring systemic therapy response as a clinical tool to optimize subsequent therapeutic regimens,and decreasing the need for surgery,with its potential for increased morbidity.The recent expansion of nanotechnology-based nanomedicine and related medical technologies provides a new approach to address the current challenges of neoadjuvant therapy for preoperative therapeutics.This review not only summarizes how nanomedicine plays an important role in a range of neoadjuvant therapeutic modalities,but also highlights the potential use of nanomedicine as neoadjuvant therapy in preclinical and clinic settings for tumor management.
