Abstract:
Brain metastases (BM) are an increasing challenge in the management of patients with advanced cancer. Treatment options for BM are limited and mainly focus on the application of local therapies. Systemic therapies including targeted therapies are only poorly investigated, as patients with BM were frequently excluded from clinical trials. Several targeted therapies have shown promising activity in patients with BM. In the present review we discuss existing and emerging targeted therapies for the most frequent BM primary tumor types. We focus on challenges in the conduction of clinical trials on targeted therapies in BM patients such as patient selection, combination with radiotherapy, the obstacles of the blood-brain barrier and the definition of study end points.
Insights
Targeted therapies show promise for brain metastases (BM) in advanced cancer. This review explores existing and emerging treatments, focusing on challenges in clinical trials for BM patients.
Area of Science:
- Oncology
- Neurology
- Pharmacology
Background:
- Brain metastases (BM) pose a significant challenge in advanced cancer care.
- Current treatment options for BM are limited, primarily relying on local therapies.
- Systemic therapies, particularly targeted therapies, are under-investigated in BM due to trial exclusions.
Purpose of the Study:
- To review existing and emerging targeted therapies for common primary tumor types of BM.
- To discuss the challenges and considerations for conducting clinical trials on targeted therapies in BM patients.
Main Methods:
- Literature review of targeted therapies for brain metastases.
- Analysis of challenges in clinical trial design for BM patients.
Main Results:
- Several targeted therapies demonstrate promising activity in patients with BM.
- Key challenges include patient selection, combination with radiotherapy, overcoming the blood-brain barrier, and defining study endpoints.
Conclusions:
- Targeted therapies represent a growing area of interest for managing brain metastases.
- Addressing clinical trial challenges is crucial for advancing systemic treatment options for BM.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
