[Current treatment of retinoblastoma. 153 children treated between 1995 and 1998].

PURPOSE

Treatment of retinoblastoma has changed significantly over the past few years. There are fewer indications for external beam radiation and a new treatment modality, chemotherapy, has appeared.

MATERIAL

and methods: We reviewed a series of 153 children treated for retinoblastoma between 1995 and 1998. There were 67 boys and 86 girls: 76 unilateral and 77 bilateral retinoblastomas. Indications for treatments and outcome were reviewed for 230 eyes and for each tumor. Age at diagnosis varied from 0 to 94 months with a median age of 12 months. A family history of retinoblastoma was found in 24 cases. Three children were seen for treatment of recurrence.

RESULTS

Among the 76 cases of unilateral retinoblastoma, 56 were enucleated and 20 were treated conservatively (5 with external beam radiation). Among the 154 eyes with bilateral retinoblastoma, 48 were enucleated and 106 were treated conservatively (49 by external beam radiation). Local treatments included chemothermotherapy, laser alone, cryotherapy, and (125)I plaques. Conservative management other than external beam radiation was used for 81 eyes and was successful in 72 (89%).

CONCLUSION

We discuss the indications and results of primary chemotherapy and local treatments. External beam radiation is still often indicated in bilaterally advanced cases. In other forms of retinoblastoma, chemothermotherapy is a very reliable and useful treatment.
