Abstract

Tumor treatments have substantially advanced through various approaches, including chemotherapy, radiotherapy, immunotherapy, and gene therapy. However, efficient treatment necessitates overcoming physiological barriers that impede the delivery of therapeutic agents to target sites. Drug delivery systems (DDSs) are a prominent research area, particularly in tumor therapy. This review provides a comprehensive overview of hydrogel-based DDSs for tumor treatment, focusing on the strategies and designs of DDSs based on the unique pathophysiological characteristics of tumors. The design and preparation of hydrogel systems for DDSs are summarized and highlighted. The challenges and opportunities for translating hydrogel-based DDSs into clinical applications are discussed.
Keywords: hydrogel; drug delivery system; antitumor therapy; combination therapy hydrogel; drug delivery system; antitumor therapy; combination therapy
