Abstract:
The authors report a case of retinocytoma showing no response to chemoreduction. A 30-month-old girl presented with Group B multifocal retinoblastoma in the right eye and Group E retinoblastoma in the left eye. After the first cycle of chemotherapy (vincristine [0.9 mg/m(2)], carboplatin [336 mg/m(2)], and etoposide [90 mg/m(2)]), there was remarkable reduction in the tumor size in the left eye, whereas the right eye tumors did not regress and were diagnosed as retinocytomas/retinomas. Retinocytoma/retinoma shows little to no response to chemoreduction.

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
