Although occupying pillar position in clinical cancer treatments, surgery itself and surgical trauma would elicit series of local/systemic inflammation-related responses that resulted in high rate of tumor recurrence. Herein, chitosan with conjugated gallic acid (CSG) molecules were coordinated with Fe3+ to form CSG/Fe3+ hydrogel for filling the tumor-resected cavity with considerable wet-adhesion ability and anti-inflammatory performance. With the assistance of doxorubicin hydrochloride (DOX center dot HCl), CSG/Fe3+/DOX hydrogel exhibited synergistic photothermal-chemo tumor-inhibited performance under near-infrared (NIR) light irradiation for eradicating residual and/or surgical trauma-recruited cancer cells. Thus, our study attempts to show a paradigm that realizes quick surgical trauma healing, inflammation inhibition and prevention of postsurgical tumor recurrence.
