Résumé
Date de début de l'étude : 26 décembre 2005
Date à laquelle le premier participant a commencé l'étude.PRIMARY OBJECTIVES: I. Determine the 2-year event-free survival of patients with Group B intraocular retinoblastoma treated with neoadjuvant chemoreduction comprising carboplatin and vincristine and standardized local ophthalmic therapy. SECONDARY OBJECTIVES: I. Determine the response rate after one course of chemoreduction (before standardized local ophthalmic therapy) in these patients. II. Correlate response rate with event-free survival in patients treated with this regimen. III. Determine the incidence of toxic effects in patients treated with this regimen. OUTLINE: This is a multicenter study. Patients receive chemoreduction comprising carboplatin IV over 60 minutes followed by vincristine IV over 1-2 minutes on day 1. Treatment repeats every 28 days for 6 courses in the absence of disease progression or unacceptable toxicity. After the first course of chemoreduction, patients undergo standardized local ophthalmic therapy comprising local laser therapy, cryotherapy, and/or radioactive plaque comprising iodine I 125 or ruthenium Ru 106. Patients are followed every 3-4 weeks until there is no active tumor seen on a minimum of 3 ophthalmic exams under anesthesia, every 6-8 weeks until 3 years of age, every 4-6 months until 10 years of age, and then annually thereafter.
