Hypoxia is a common feature of the tumor microenvironment, which is characterized by tissue oxygen deficiency due to an aggressive proliferation of cancer cells. Hypoxia activates hypoxia-inducible factor-dependent signaling, which in turn regulates metabolic reprogramming, immune suppression, resistance to apoptosis, angiogenesis, metastasis, and invasion to secondary sites. In this review, we provide an overview of the use of nanotechnology to harmonize intra-tumoral oxygen or suppress hypoxia-related signaling for an improved efficacy of cancer treatment. The biological background was followed by conducting a literature review on the (1) nanoparticles responsible for enhancing oxygen levels within the tumor, (2) nanoparticles sensitizing hypoxia, (3) nanoparticles suppressing hypoxia-inducing factor, (4) nanoparticles that relieve tumor hypoxia for enhancement of chemotherapy, photodynamic therapy, and immunotherapy, either individually or in combination. Lastly, the heterogeneity of cancer and limitations of nanotechnology are discussed to facilitate translational therapeutic treatment.

Berberine (BBR) is an isoquinoline alkaloid with a variety of biological activities, including anti-microbial and anti-tumoral activities. However, the cellular targets of BBR and the roles of BBR in the radiosensitivity of breast cancer cells are not well defined. In this study, we investigated the effects of BBR on the radiosensitivity of BT549 triple-negative breast cancer cells.

Ferroptosis, a controlled cell death influenced by iron-dependent lipid peroxidation, presents potential therapeutic targets for cancer treatment due to its unique molecular pathways and potential drug resistance. Natural compounds, such as polyphenols, flavonoids, terpenoids and alkaloids, can influence ferroptosis via important signalling pathways, such as Nrf2/Keap1, p53, and GPX4. These are promising for combinational therapy due to their ability to cause ferroptotic death in cancer cells, exhibit tumour-specific selectivity and reduce systemic toxicity.

Moyamoya syndrome (MMS) is a chronic vasculopathy characterized by progressive stenosis of intracerebral arteries, leading to an increased risk of stroke. Children with Down syndrome (DS) are at an increased risk of co-occurring medical conditions, including MMS and leukemia. We report four patients with the triad of DS, MMS, and acute lymphoblastic leukemia (ALL).

Acute leukaemias are the commonest cancers in children and young people (CYP). Off-treatment surveillance is assumed to improve relapse detection, but whether this affects subsequent survival and quality of life is unclear. This systematic review searched 13 databases and two trial registries in December 2022.

Background: Local control strategies in pediatric oncology are guided by disease-specific considerations. Effective communication of the goals of surgical procedure and associated intraoperative events plays a crucial role in shaping subsequent treatment decisions. However, accurately and comprehensively documenting these findings remains challenging, with considerable variability across different tumor types.
