Corticosteroids (CSs), widely used in oncology for their anti-inflammatory and immunosuppressive properties, help manage cancer-related symptoms and side effects. However, their long-term use may negatively affect patient survival and exacerbate tumor progression.

• Elevated glucose and glutamine metabolism,
• disruption of vitamin D levels, and
• alterations in the microbiome

are some of the key factors contributing to these adverse outcomes.
Approaches such as ketogenic diets, fasting, sartans, and vitamin D supplementation have shown promise in providing similar benefits to CSs while mitigating the risks associated with the mechanisms identified as contributing to tumor progression. This perspective underscores the necessity for a reevaluation of CSs use in cancer care and advocates for further research into safer, more effective therapeutic strategies.
