Choroid plexus tumors (CPTs) are rare neuroepithelial tumors primarily affecting the pediatric population. CPTs usually occur in the ventricles of the brain. At Alfa Cytology, we are committed to pioneering new therapeutic approaches for choroid plexus tumors therapy for our clients.
Introduction to Choroid Plexus Tumors
The cerebrospinal fluid produced by choroid plexus tissue surrounds the brain and spinal cord, so as choroid plexus tumors grow, they block the flow of cerebrospinal fluid. CPT can be classified as benign or malignant.
Choroid Plexus Papillomas (CPP)
CPP is the most common. Approximately 80% of choroid plexus tumors are CPP. These tumors are slow growing and have a low likelihood of spreading.
Choroid Plexus Carcinoma (CPC)
CPC is a cancerous form of choroid plexus tumor. About 10-20% of choroid plexus tumors are CPCs, which grow more rapidly and are more likely to spread to other tissues through the cerebrospinal fluid.
CPTs are particularly significant due to their association with genetic syndromes, such as Li-Fraumeni syndrome (LFS), characterized by germline mutations in the TP53 gene. Epidemiological studies indicate that approximately 40% of children diagnosed with CPC may have underlying LFS, highlighting the importance of genetic predisposition in tumor development.
Therapeutic Development for Choroid Plexus Tumors
The therapeutic landscape for CPTs has improved with advances in chemotherapy and surgery. High-dose chemotherapy (HDCx) followed by autologous hematopoietic progenitor cell rescue (AuHPCR) has shown promising survival rates, with about 58% of children remaining CPC-free at ten years. Additionally, targeted therapies are emerging as vital advancements in CPT treatment. Preclinical studies have identified key molecular targets, such as mTOR, ATR, and CDK, involved in tumor growth and survival.
