In which type of cancers is the presence of hormone receptors a key prognostic indicator?

The presence of hormone receptors is particularly relevant and serves as a key prognostic indicator in breast cancer. Breast cancer can be classified based on the presence of specific hormone receptors, such as estrogen receptors (ER) and progesterone receptors (PR). Patients whose tumors test positive for these receptors typically have a better prognosis and may benefit from hormone therapies, such as tamoxifen or aromatase inhibitors, which can significantly reduce the risk of recurrence and improve survival. This reliance on hormone receptor status in guiding treatment decisions and anticipating disease outcomes makes it a central focus in the management of breast cancer.

In contrast, other cancers listed, such as liver cancer, pancreatic cancer, and lung cancer, do not have a similar reliance on hormone receptor status for prognostic evaluation or treatment decisions. While some may express certain receptors, they are not routinely used as a standard prognostic tool in the same way as in breast cancer.
