What is the primary purpose of sanctuary chemotherapy?

The primary purpose of sanctuary chemotherapy is to administer chemotherapy to areas with malignant cells that are not directly accessible. This type of chemotherapy is specifically used to target tumors located in "sanctuary sites," where traditional chemotherapy may not adequately penetrate due to physical barriers or the unique biological environment of those areas, such as the central nervous system or certain lymphatic tissues.

By focusing treatment on these less accessible regions, sanctuary chemotherapy aims to effectively eliminate malignant cells that may otherwise evade standard systemic treatments. This approach recognizes that certain cancers can hide or persist in these protected areas, necessitating a tailored strategy to ensure comprehensive treatment and improve overall outcomes for the patient.
