The technique called intra-arterial chemotherapy for retinoblastoma is used to treat an intraocular tumor
The Hospital of Clinics of the Federal University of Pernambuco (UFPE) performed a surgical procedure unheard of in the north-north-east. This is the intra-arterial chemotherapy for retinoblastoma (Quiare), intended to treat intraocular tumors, which appears most often in children. The technique had already been performed in hospitals in São Paulo and Rio de Janeiro. With this advance, the HC became the fourth hospital to occur at Quiare.
The beneficiary of the proceedings, which occurred in the second half of December, was a 3-year-old child who had undergone an operation in the left eye because of a retinoblastoma and whose disease had progressed to the right eye. With the procedure, the chances of tumor control have increased, which prevents the final blindness of the child, according to the project coordinator Quiare, the oncological ophthalmologist Virgínia Torres. "The treatment was performed using a delicate catheter inserted into the femoral artery of the groin, penetrating so finely into the ophthalmic artery where chemotherapy had been injected , allowing high concentrations in the ocular tumor region, without the side effects of systemic chemotherapy. "
Malignant neoplasm
Retinoblastoma is the malignant intraocular tumor that comprises 10 to 15% of cancers occurring during the first month of life. The appearance of cancer is related to mutations in the affected child's cells and can affect one or both eyes. According to a study by the National Cancer Institute (Inca), the incidence of retinoblastoma in Brazil is twice as high as in the United States and Europe.
Leucocoria is the most common form of clinical presentation, with 75%, also called "cat's eye", followed by strabismus. The pediatrician or ophthalmologist makes the diagnosis by ultrasound and ocular ultrasound
. The Hospital das Clínicas has recently acquired a wide field RetCam® digital camera that allows for greater accuracy in the initial documentation of retinoblastoma as well as periodic monitoring. treatment
