Although postsurgical chemotherapy is frequently used for the treatment of breast cancer, tumor recurrence is still a frequent event. Enhancing the efficacy of chemotherapy via localized drug delivery may help to prevent breast cancer recurrence. To achieve this goal, we designed a hydrogel nanocarrier that could be injected at the tumor site by coassembly of tailor-made hexapeptide and doxorubicin. Evidently, on the basis of our findings, the sustained release of drug from the hydrogel led to a reduction in cancer recurrence, including the suppression of primary regrowth and distant metastasis. This localized chemotherapy strategy did not show any obvious side effects in vivo and represents a promising adjuvant therapeutic strategy for breast cancer recurrence.
