Treatment options

Evidence-based approaches to managing this condition.

First-line treatments

1

Maximal Safe Resection

Aggressive surgical debulking when feasible remains a cornerstone treatment, aiming to remove the maximum safe amount of tumor tissue. Intraoperative mapping and monitoring help preserve critical neurological functions during resection.

3

Craniospinal Irradiation

Full craniospinal radiation with boost to the tumor bed is standard for adult PNETs. Treatment planning uses advanced techniques to conform radiation to target volumes while sparing normal brain and spinal cord tissue.

Additional treatment options

Adjuvant Chemotherapy

Multi-agent chemotherapy regimens, often including vincristine, lomustine, and cyclophosphamide, may be used adjuvantly. Treatment requires regular hematologic monitoring and supportive care for side effects.

Neurorehabilitation

Comprehensive rehabilitation including physical, occupational, and speech therapy helps patients recover functional abilities affected by tumor or treatment. Programs are tailored to individual deficits and progressive goals.
