Docetaxel Resistance in Breast Cancer: Current Insights and Future Directions

Area of Science:

• Oncology
• Pharmacology
• Molecular Biology

Background:

• Docetaxel is a vital chemotherapy for breast cancer.
• Drug resistance and toxicity limit its clinical effectiveness.
• Understanding resistance mechanisms is crucial for improving patient outcomes.

Purpose of the Study:

• To review molecular mechanisms of docetaxel resistance in breast cancer.
• To discuss advances and future directions for overcoming resistance.
• To highlight the multifactorial nature of resistance.

Main Methods:

• Literature review of molecular mechanisms of drug resistance.
• Analysis of recent advances in therapeutic strategies.
• Examination of evolutionary perspectives on resistance.

Main Results:

• Identified key resistance mechanisms: target alteration, drug efflux, apoptosis suppression, EMT, and cancer stem cells.
• Highlighted intrinsic vs. acquired resistance and need for adaptive therapies.
• Reviewed advances in genomics, non-coding RNAs, drug combinations, and biomarkers.

Conclusions:

• Docetaxel resistance is multifactorial, requiring multifaceted interventions.
• Targeting resistance mechanisms with novel agents and combinations can improve outcomes.
• Further research into biomarkers and adaptive therapies is essential for enhancing breast cancer treatment.
