There are several classification systems available for retinoblastoma. As the treatment of the tumor has evolved, a new classification system has been introduced. For intraocular disease, the available grouping systems include International Intraocular<unk>  (IIRC), Intraocular Classification of Retinoblastoma (ICRB), and cTNMH systems. For extraocular disease, the International Retinoblastoma Staging System (IRSS) and cTNMH schemes can be used.
