Q&As

What are the clinical implications of ESR1 mutations in breast cancer?

ESR1 mutations can lead to resistance to endocrine therapies in breast cancer patients, impacting treatment outcomes.

How does ESR1 testing impact the prognosis of breast cancer patients?

ESR1 testing can provide important prognostic information by helping to predict the likelihood of a favorable response to hormone therapy.

How is ESR1 protein detected in clinical practice?

ESR1 protein can be detected through various laboratory techniques, including immunohistochemistry (IHC) and immunoblotting.

Can ESR1 mutations be targeted in breast cancer treatment?

Research is ongoing, and there are efforts to develop targeted therapies for ESR1-mutated breast cancer, but it's still an evolving field.

How is ESR1 status determined in breast cancer patients?

ESR1 status is determined through the examination of tumor tissue samples, often using IHC or molecular testing.
