Alternate Title

Cisplatin and Etoposide Prior to Radiation Therapy in Treating Patients With CNS Tumors

Basic Trial Information

Phase	Type	Status	Age	Sponsor	Protocol IDs
Phase II	Treatment	Closed	3 and over	NCI	MAYO-891351 NCI-T92-0208D, NCT00002472, T92-0208

Objectives

1. Determine the response rate of patients with newly diagnosed CNS germ cell tumors treated with cisplatin and etoposide.
2. Determine the survival of patients with CNS germ cell tumors treated with cisplatin and etoposide followed by cranial radiotherapy.
3. Determine endocrine and cognitive function in these patients before and after receiving this regimen.

Entry Criteria

Disease Characteristics:

• Histologically proven CNS germ cell tumor of 1 of the following subtypes:
  • CNS germinoma
  • Immature teratoma
  • Embryonal cell carcinoma
  • Yolk sac tumor
  • Endodermal sinus tumor
  • Choriocarcinoma

  OR




• Pineal or suprasellar mass associated with elevated CSF alpha fetoprotein or beta-human chorionic gonadotropin allowed



• Patients 18 years and over with localized pure germinomas ineligible



• Evaluable CT or MRI of brain and/or spinal cord required

Prior/Concurrent Therapy:

Biologic therapy:

• Not specified

Chemotherapy:

• No prior chemotherapy for CNS germ cell tumor

Endocrine therapy:

• Concurrent corticosteroids allowed except as antiemetics

Radiotherapy:

• No prior cranial or spinal radiotherapy

Surgery:

• Not specified

Patient Characteristics:

Age:

• 3 and over

Hematopoietic:

• Age 18 and over:
  • WBC at least 4,000/mm³
  • Platelet count at least 100,000/mm³
• Under age 18:
  • Absolute neutrophil count at least 1,000/mm³
  • Platelet count at least 100,000/mm³

Hepatic:

• Not specified

Renal:

• Creatinine no greater than 0.3 mg/dL above upper limit of normal for age

Other:

• No uncontrolled infection
• Not pregnant or nursing
• Negative pregnancy test
• Fertile patients must use effective contraception

Expected Enrollment

A total of 12-25 patients with germinoma will be accrued for this study within 3-6 years. A total of 12-25 patients with nongerminoma will be accrued for this study within 6-12 years.

Outcomes

Response rate
Survival
Endocrine and cognitive function

Outline

Patients are stratified by histology (germinoma vs nongerminoma).

Patients receive cisplatin IV over 4 hours followed by etoposide IV over 30-60 minutes on days 1-5. Treatment continues every 3 weeks for 4 courses in the absence of disease progression or unacceptable toxicity. After completion of 4 courses, patients with nongerminoma who achieve complete response (CR) and all patients with germinoma proceed to radiotherapy. After completion of 4 courses, patients with nongerminoma who achieve less than CR undergo resection of any residual cranial masses, if feasible, and then proceed to radiotherapy. Patients who experience disease progression or unacceptable toxicity during chemotherapy are restaged and proceed directly to radiotherapy.

Beginning a minimum of 3 weeks after completion of the last course of chemotherapy and after recovering from any toxic effects of chemotherapy, eligible patients undergo a regimen of craniospinal axis irradiation and/or localized cranial or spinal field irradiation based on histology, extent of disease, and response to chemotherapy. Patients with gross spinal meningeal disease after completion of chemotherapy undergo radiotherapy boost.

Patients are followed every 2 months for 1 year, every 4 months for 1 year, every 6 months for 1 year, and then annually for 2 years.
