Targeted Therapy for Brain Tumors
Targeted therapy is a precision cancer treatment that focuses on specific genetic changes, proteins, or molecular pathways that help cancer cells grow and survive. For certain brain tumors, targeted treatment may be considered when testing identifies a biomarker that can be matched with an appropriate medicine.
How Targeted Therapy Works
Unlike treatments that affect many rapidly dividing cells, targeted medicines are designed to act on specific characteristics of cancer cells. Depending on the medicine and tumor type, treatment may block signals responsible for tumor growth, interfere with cancer-cell survival, or help the immune system recognize abnormal cells.
Biomarker Testing and Treatment Planning
Not every brain tumor responds to targeted therapy. Your neuro-oncology team may recommend biomarker testing, molecular profiling, or genetic testing of tumor tissue to identify changes that could make a targeted treatment appropriate. The results, tumor type, location, stage, previous treatments, and overall health are considered when developing an individualized treatment plan.
Side Effects and Monitoring
Targeted therapy can still cause side effects, which vary according to the medicine. Possible effects include fatigue, diarrhea, liver problems, skin changes, mouth sores, high blood pressure, and nail changes. Regular medical reviews, blood tests, and imaging may be used to monitor treatment response and safety.
