Editorial: Managing cancer metastasis by tackling anticancer drug resistance.

This document is an editorial published in Frontiers in Pharmacology discussing the challenges of drug resistance and tumor metastasis in cancer treatment. It emphasizes the importance of understanding the underlying mechanisms to develop effective therapeutic strategies. The document includes summaries of three research articles on drug resistance in metastatic colorectal cancer, ovarian cancer treatment, and small molecule therapies targeting estrogen receptors in breast cancer. The goal of the research is to overcome drug resistance, alleviate the burden of metastatic cancers, and improve patient outcomes. The document acknowledges the contributions of the authors and reviewers and declares financial support for the research. [Extracted from the article]
