Detailed Description

Retinoblastoma is the commonest primary intraocular malignancy in infancy and early childhood. Ophthalmologist are trying to seek other more safe and effective treatment modalities to well control the tumor and preserve the visual function. Photodynamic therapy (PDT) is a potentially therapeutic approach for retinoblastoma which has been underestimated. In this study, we are gonging to investigate the the effectiveness and safety profiles of photodynamic therapy (PDT) for the treatment of human retinoblastoma.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: PDT treatment group
All the patients received once PDT with Visudyne® as the initial treatment. Rescue treatment with systemic chemotherapy would be given to patients if tumors were insensitive to PDT treatment, the tumors became larger, or disease relapse.
PDT with Visudyne® was performed under general anesthesia according to the standard TAP study with some modifications: Verteporfin (6 mg/m2, Visudyne®; Novartis International AG, Basel, Switzerland) was injected intravenously with a standard 10-min infusion followed by followed by application of diode laser (Opal Photoactivator; Coherent Medical Group, Santa Clara, USA) (689 nm, 50 J/cm2, 600 mW/cm2) for 200 seconds to generate 120 J/cm2.
Other Names:
  • systemic chemotherapy
  • Laser photocoagulation
  • Cryotherapy
