Abstract:
Objective To explore the value of seeking tumor cells through cerebrospinal fluid in the metastasis and prognosis of retinoblastoma.Methods Two hundred and fifty-six cases clinic diagnosed retinoblastoma were collected,154 cases were boys and 102 cases were girls.There were 85 children with bilateral disease and 171 children with unilateral disease.Lumbar puncture was examined before treatment,compare the result and prognosis.Children who were found tumor cells in their cerebrospinal fluid were treated with 6 to 9 cycles of systemic chemotherapy with CTV(carboplatin,teniposide and vincristine)protocol and 8 to 10 intrathecal injections with cytrarabine,methotrexate and dexametha-sone.Follow-up were between 8 to 23 months,the mean time was 14.6 months.Results There were 8 cases found tumor cells in their cerebrospinal fluid in all 256 children,one of them died of wide spread intracranial metastasis;the other patient was given high dose chemotherapy with autologous perip-heral stem cell transplantation(APBSCT) because of intracranial metastasis,follow-up to now the patient′s condition was stable.The rest 6 children were enucleated in follow-up period,there were 4 cases(67%) with the histopathology of the eye indicates spread of tumour cells beyond the lamina cribrosa,and 2 cases with invading the cut end of the optic nerve.Six children were no metabasis evidences at other tissues.Conclusions Intracranial metastasis is the common metastasis style in retinoblastoma,so lumbar puncture to seeking tumor cells was important to evaluate intracranial metastasis,early treatment and prognosis.
