Observation and/or Combination Chemotherapy After Surgery or Biopsy in Treating Young Patients With Extracranial Germ Cell Tumors

Phase 3
Conditions
Childhood Germ Cell Tumor
Extragonadal Germ Cell Tumor
Ovarian Cancer
Registration Number
NCT00274950
Lead Sponsor
Children's Cancer and Leukaemia Group
Brief Summary

RATIONALE: Sometimes, after surgery, the tumor may not need additional treatment until it progresses. In this case, observation may be sufficient. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug (combination chemotherapy) may kill more tumor cells. Giving combination chemotherapy after surgery may kill any remaining tumor cells.

PURPOSE: This phase III trial is studying how well observation and/or combination chemotherapy works after surgery or biopsy in treating young patients with extracranial germ cell tumors.

Detailed Description

OBJECTIVES:

* Stratify and reduce treatment for pediatric patients with extracranial germ cell tumors while maintaining event-free survival.

* Treat newly diagnosed patients with extracranial germ cell tumors requiring chemotherapy with a carboplatin-based strategy.

* Develop a common strategy for the treatment of patients with recurrent or progressive extracranial germ cell tumors.

* Register all cases of mature and immature teratoma.

* Develop a common strategy for the management of immature and mature teratoma, including follow-up strategies to permit early detection of yolk sac recurrence.

OUTLINE: This is a multicenter study.

Patients who have not had prior biopsy or surgical resection undergo biopsy (if feasible) or surgical resection. Patients with mature or immature teratoma undergo observation. These patients who relapse (i.e., tumor regrowth) may undergo further surgical resection unless tumor markers are significantly elevated. If the tumor markers are significantly elevated, these patients proceed to JEB chemotherapy according to risk group. Patients with all other malignant germ cell tumors are assigned to 1 of 3 treatment groups according to risk.

* Low-risk group: Patients with normal tumor markers undergo observation. Patients with rising tumor markers only AND no imageable tumor proceed to treatment as in the intermediate-risk group. Patients with rising tumor markers AND/OR imageable tumor are considered to have relapsed and proceed to treatment as in the intermediate- or high-risk group.

* Intermediate-risk group: Patients receive JEB chemotherapy comprising etoposide IV over 4 hours on days 1-3, carboplatin IV over 1 hour on day 2, and bleomycin IV over 30 minutes on day 3. Treatment repeats every 21 days for 4 courses. Patients with residual tumors after completion of chemotherapy may undergo second-look surgery.

* High-risk group: Patients receive JEB chemotherapy as in the intermediate-risk group for 6 courses. Patients with residual tumors after completion of chemotherapy may undergo second-look surgery.

* Relapse therapy: Patients in the intermediate- or high-risk group who relapse after completion of JEB chemotherapy receive vinblastine IV on days 1 and 2, ifosfamide IV over 1 hour on days 1-5, and cisplatin IV on days 1-5. Treatment repeats every 21 days for 6 courses.

PROJECTED ACCRUAL: A total of 105 patients will be accrued for this study.
