Low Dose vs High Dose Chemotherapy: Pros and Cons Explored

Chemotherapy is a widely used treatment for cancer, with varying dosages employed to achieve desired outcomes. In recent years, low-dose chemotherapy has gained attention as a new strategy for controlling cancer. A meta-analysis comparing low-dose and conventional-dose chemotherapy found that low-dose chemotherapy can achieve the same desired potency as conventional doses, with no differences in overall survival, progression-free survival, and objective response rate. Additionally, low-dose chemotherapy resulted in significantly fewer severe adverse events, such as mucositis, thrombocytopenia, anemia, and febrile neutropenia.

However, there is a lack of standardization in terms of drug quantization, dose fractionation, repetition frequency, and duration of treatment for low-dose chemotherapy. This lack of consistency can hinder the effectiveness of low-dose chemotherapy in the long-term by allowing drug-resistant tumor cells to spread. As an alternative approach, adaptive therapy, which involves administering high initial doses followed by progressively lower doses, has shown promise in controlling cancer growth and preventing relapses.

To fully exploit the potential of low-dose chemotherapy in curing chronic and complicated diseases, further research and standardization of low-dose metronomic therapy are needed. These efforts will help optimize treatment outcomes and ensure the best possible care for cancer patients.

Key Takeaways:

  • Low-dose chemotherapy achieves the same potency as conventional doses with no significant differences in overall survival, progression-free survival, and objective response rate.
  • Low-dose chemotherapy results in significantly fewer severe adverse events, such as mucositis, thrombocytopenia, anemia, and febrile neutropenia.
  • There is a lack of standardization in drug quantization, dose fractionation, repetition frequency, and duration of treatment for low-dose chemotherapy.
