Tumors consist of a heterogeneous population of cancer cells carrying multiple genetic mutations. During the past few decades, efforts have focused on curing cancer using various methods. However, traditional cancer therapies still carry some drawbacks, such as limited application for only a few cancer types, killing of normal cells, poor specificity, and associated toxicity. To overcome these disadvantages, drug-delivery methods that emphasize biomaterials have been developed and applied to optimize cancer treatments. Hydroxyapatite (HAP) is a biocompatible inorganic material that can be applied in biomedical drug-delivery applications. This review discusses the features and properties of HAP that make it an effective biomaterial and provides a comprehensive summary of recent studies in which HAP and composites containing HAP were applied as anticancer drug carriers. We believe that HAP-based composites show great promise for cancer treatment using controlled release of therapeutic agents, leading to enhanced efficiency, selective release of drugs, and prohibition of cancer cell proliferation.

Background: The Arp2/3 complex is a key regulator of tumor metastasis, and targeting its subunits offers potential for anti-metastatic therapy. However, the expression profiles, prognostic relevance, and diagnostic value of its subunits across cancers remain poorly understood. This study aims to investigate the clinical relevance of Arp2/3 complex subunits, particularly ARPC1A, in pan-cancer, and to further analyze the potential biological mechanisms of ARPC1A, as well as its association with immune infiltration and chemotherapy drug sensitivity.

Despite significant strides in improving cancer survival rates, the global cancer burden remains substantial, with an anticipated rise in new cases. Immune checkpoints, key regulators of immune responses, play a crucial role in cancer evasion mechanisms. The discovery of immune checkpoint inhibitors (ICIs) targeting PD-1/PD-L1 has revolutionized cancer treatment, with monoclonal antibodies (mAbs) becoming widely prescribed.

Chemotherapy is widely recognized as a highly efficacious modality for cancer treatment, involving the administration of chemotherapeutic agents to target and eradicate tumor cells. Currently, oral administration stands as the prevailing and widely utilized method of delivering chemotherapy drugs. However, the majority of anti-tumor medications exhibit limited solubility and permeability, and poor stability in harsh gastrointestinal environments, thereby impeding their therapeutic efficacy for chemotherapy.
