    Alphafetoprotein is a useful tumor marker for primary intracranial germ-cell tumors. Its levels in serum and cerebrospinal fluid can predict tumor type and monitor treatment effectiveness, aiding in early detection of recurrence.

    Area of Science:

    • Neuro-oncology
    • Biomarker Discovery
    • Pediatric Oncology

    Background:

    • Primary intracranial germ-cell tumors (GCTs) are rare but serious malignancies in children.
    • Accurate diagnosis and monitoring of treatment response are crucial for patient outcomes.
    • Alphafetoprotein (AFP) is a known tumor marker, but its role in intracranial GCTs requires further elucidation.

    Observation:

    • A case study of a 12-year-old girl with an AFP-producing pineal region brain tumor is presented.
    • AFP levels were measured in serum and cerebrospinal fluid (CSF).
    • Tumor recurrence was associated with rising AFP levels.

    Findings:

    • The patient's tumor was histopathologically diagnosed as an endodermal sinus tumor.
    • AFP was detected within the tumor cells via immunofluorescence.

  • AFP levels decreased with irradiation and chemotherapy, and increased upon tumor recurrence.

    • Implications:

    • Alphafetoprotein can serve as a specific and sensitive biomarker for intracranial GCTs.
    • AFP monitoring can aid in predicting tumor histopathology.
    • AFP levels are valuable for assessing therapeutic response and detecting recurrence in pediatric GCT patients.
