The management and treatment of tumor complications pose continuous challenges due to the inherent complexity. However, the advent of drug delivery systems (DDSs) brings promising opportunities to address the tumor complications using innovative technological approaches. This review focuses on common oncological complications, including cancer thrombosis, malignant serous effusion, tumor-associated infections, cancer pain, and treatment-related complications. Emphasis was placed on the application and potential of DDSs in mitigating and treating these tumor complications, and we delved into the underlying mechanisms of common cancer-associated complications, discussed the limitations of conventional treatments, and outlined the current status and potential development of DDSs for various complications in this review. Moreover, we have discussed the existing challenges in DDSs research, underscoring the need for addressing issues related to biocompatibility and targeting of DDSs, optimizing drug delivery routes, and enhancing delivery efficiency and precision. In conclusion, DDSs offer promising avenues for treating cancer complications, offering the potential for the development of more effective and safer drug delivery strategies, thereby improving the quality of life and survival rates of cancer patients.

This study investigates a multifunctional hydrogel system integrating carboxymethyl cellulose (CMC) in a 3D-printed limonene (LIM) scaffold coated with poly(3,4-ethylenedioxythiophene): polystyrene sulfonate (PEDOT:PSS). The system allows to enhance wound healing, prevent infections, and monitor the healing progress. CMC is crosslinked with citric acid (CA) to form the hydrogel matrix (CMC-CA), while the 3D-printed limonene (LIM) scaffold is embedded within the hydrogel to provide mechanical support.

Persistent bacterial infections remain a major challenge in wound management. Although drug-loaded wound dressings have gained increasing attention, their therapeutic efficacy is often hindered by uncontrolled drug release and a lack of electrical signal responsiveness. Herein, an antibacterial dressing (CCS-PC) with electroactivity and stimulus-responsive drug release properties was fabricated via electro-assembly, wherein chitosan and ciprofloxacin hydrochloride (CIP) were co-deposited onto polypyrrole (PPy)-coated gauze.

Triple-negative breast cancer (TNBC) remains a formidable clinical challenge due to its aggressive behavior, lack of therapeutic targets, and poor prognosis. The PI3K/AKT/mTOR pathway is highly activated in TNBC, making it a promising therapeutic target. Conventional PEGylated nanocarriers often face challenges, such as accelerated blood clearance and lysosomal trapping.

Covalent organic frameworks (COFs) have been emerging as versatile reticular materials due to their tunable structures and functionalities, enabled by precise molecular engineering at the atomic level. While the integration of multiple components into COFs has substantially expanded their structural complexity, the strategic engineering of diverse functionalities within a single framework the random distribution of linkers with varying lengths remains largely unexplored. Here, we report a series of highly crystalline mixed-length multivariate COFs synthesized using azobenzene and bipyridine as linkers, where tuning the ratio of linkers and incorporating palladium effectively modulates the balance between near-infrared (NIR) light absorption and catalytic sites for NIR-generation of hydrogen peroxide (HO).
