This study highlights the effectiveness of a multidisciplinary approach for treating primitive neuroectodermal tumors (PNET) in pediatric patients. Early chemotherapy is crucial for achieving remission and avoiding extensive surgery.

Area of Science:

  • Pediatric Oncology
  • Surgical Oncology
  • Radiation Oncology

Background:

  • Primitive neuroectodermal tumors (PNET) are aggressive soft tissue neoplasms primarily affecting children and adolescents.
  • Effective treatment strategies are crucial for improving patient outcomes.

Purpose of the Study:

  • To review the therapeutic experience with a multidisciplinary approach for PNET.
  • To evaluate the efficacy of combining surgery, chemotherapy, and radiation therapy.

Main Methods:

  • Retrospective review of 13 pediatric patients treated between 1986 and 1998.
  • Treatment followed the German Society of Pediatric Oncology's soft tissue protocol (CWS).
  • Multimodal therapy included neoadjuvant chemotherapy, surgical excision, and adjuvant radiotherapy.

Main Results:

  • Neoadjuvant chemotherapy achieved partial remission in all patients, enabling less mutilating surgery.
  • Eight out of 13 patients achieved full remission with long-term follow-up.
  • Five patients died, with an average survival of 20 months.

Conclusions:

  • A multidisciplinary approach integrating chemotherapy, surgery, and radiotherapy is essential for PNET management.
  • Chemotherapy as the initial treatment is mandatory to prevent mutilating surgery and intraoperative tumor spread.
  • Close collaboration among pediatric oncologists, surgeons, and radiation oncologists is vital for optimal PNET care.
