[Radiotherapy in the multimodality treatment of retinoblastomas in children]
Abstract:
The results of multimodality therapy of 50 children with uni- or bilateral retinoblastoma were assessed. Gamma-beam therapy with the application of a special protective collimator and polychemotherapy were used as modalities supplementing eye extirpation. Some patients were irradiated prior to operation, the others following it. Despite a slight decrease in a tumor radiation dose in the first group, 2-year survival rates in both groups were the same. Of 32 patients 30 (94%) in both groups have been alive for 2 yrs. without signs of disease after multimodality therapy. Patients with Stage I retinoblastoma were subjected to chemo- and radiotherapy; 16 out of 18 patients have been alive for 2 yrs. It has been stressed that radiation therapy is an important component in multimodality therapy. It can be used as a modality of the combined method of tumor surgical removal or as a method of radical therapy in early forms of the disease.

02:49Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
