ABSTRACT
The progress of modality therapy has improved both survival rate and quality of life of retinoblastoma(RB) patients.However,some problems are still left and unsolved.Parts of the RB relapse after they are treated for the first time.Even more remarkable,the related individuals to the RB patients run a risk of RB.Gene diagnosis and treatment are emerging and appear to solve these problems.Some researches in developed countries and Hong Kong have successfully made progress in gene diagnosis of RB.However,the detection rate of Rb1 gene mutation is very low.Researches documented for many years that gene diagnosis for RB is extremely complex,so we should go further to achieve a goal of gene diagnosis.Gene diagnosis of RB is still an initiation in China.We should strengthen relevant study and spread this technique.
