RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Bone marrow transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells.
PURPOSE: Phase II trial to study the effectiveness of combination chemotherapy plus radiation therapy followed by bone marrow transplantation in treating patients who have retinoblastoma.
- Evaluate the feasibility of sequential therapy with carboplatin, etoposide, cyclophosphamide, doxorubicin, topotecan and radiotherapy followed by autologous bone marrow transplantation in patients with extrachoroidal or metastatic retinoblastoma.
- Assess this treatment regimen in terms of response and toxicity before and after autologous bone marrow transplantation in this patient population.
OUTLINE: Patients receive carboplatin IV on day 1 and etoposide IV over 1 hour daily on days 1-3 of weeks 0, 6, and 12, plus cyclophosphamide IV or orally daily on days 1-7, doxorubicin IV on day 8 and carboplatin IV over 1 hour on day 10 on weeks 3, 9, and 15. Beginning on week 6, patients receive concurrent radiotherapy 5 days a week over 4-6 weeks. Patients with meningeal involvement receive topotecan intrathecally twice weekly for 3 weeks and then weekly for 3 weeks before starting radiotherapy. Beginning one day after each treatment course, patients receive filgrastim (G-CSF) subcutaneously daily for 10 days.
Patients undergo bone marrow collection before or after week 6. Following hematologic recovery, patients receive several days of high dose chemotherapy consisting of cyclophosphamide and topotecan followed by bone marrow reinfusion.
Patients are followed at 6, 9, and 12 months, and then every 6 months for 4 years.
PROJECTED ACCRUAL: A total of 10 patients will be accrued for this study.

A pharmaceutical preparation of sitagliptin phosphate and metformin hydrochloride that is used in the treatment of TYPE 2 DIABETES.
A semisynthetic derivative of PODOPHYLLOTOXIN that exhibits antitumor activity. Etoposide inhibits DNA synthesis by forming a complex with topoisomerase II and DNA. This complex induces breaks in double stranded DNA and prevents repair by topoisomerase II binding. Accumulated breaks in DNA prevent entry into the mitotic phase of cell division, and lead to cell death. Etoposide acts primarily in the G2 and S phases of the cell cycle.
A benzamide derivative that is used as a dopamine antagonist.
