Abstract

Purpose: To evaluate the feasibility and safety of adenovirus-mediated gene therapy as a treatment for tumor seeds in the vitreous of children with retinoblastoma. Patients and Methods: An Institutional Biosafety Committee–, Institutional Review Board–, Recombinant DNA Advisory Committee–, and US Food and Drug Administration–approved phase I study used intrapatient dose escalation of adenoviral vector containing a herpes simplex thymidine kinase gene (AdV-TK) followed by systemic administration of ganciclovir to treat bilateral retinoblastoma with vitreous tumor seeding refractory to standard therapies. Vitreous tumor seeds were treated by intravitreous injection of AdV-TK adjacent to disease sites. Each injection was followed by ganciclovir delivered intravenously every 12 hours for 7 days. Results: Eight patients with vitreous tumor seeds were enrolled. One patient who was treated with 10 8 viral particles (vp) had resolution of the tumor seeds around the injection site. The seven patients who were treated with doses ≥ 10 10 vp had resolution of their vitreous tumor seeds documented by fundoscopy. Toxicity included mild inflammation at 10 10 vp and moderate inflammation, corneal edema, and increased intraocular pressure at 10 11 vp. One patient was free of active vitreous tumor seeds 38 months after therapy. There has been no evidence of extraocular spread of tumor along the needle tract in any patient. Conclusion: AdV-TK followed by ganciclovir can be administered safely to children with retinoblastoma. Suicide gene therapy may contribute to the treatment of children with retinoblastoma tumor seeds in the vitreous, a resistant complication of retinoblastoma.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
