Reduction in Radiotherapy for Childhood Brain Tumours Unsucessful


A research study, Radiotherapy after high-dose chemotherapy with autologous hematopoietic cell rescue: Quality assessment of Head Start III, published in Paediatric Blood & Cancer, shows that reduced Radiation Therapy results in worse outcomes.

This study shows that attention to the timing, dose, and location of radiation therapy is crucial,” Kenneth K. Wong, MD, a radiation oncologist at Children’s Hospital Los Angeles and first author on the study.

The paper is a qualitative assessment of the Head Start III trial which avoids or delays Radiation Therapy in children with brain tumours. The studies represent an innovative approach to the treatment of malignant brain tumours – using high dose Chemotherapy followed by transfusion of blood stem cells – as a substitute for radiation in younger children, where the late side effects of radiation to the developing brain can be particularly detrimental. If disease persists after this course of treatment or if the child is older, they receive radiation therapy.

In the latest Head Start III study, only 31 of 220 children received radiation – of those, a subset (8 of 25), consisting of  children 6 years of age or younger, had deviations from the treatment plan.

Parents or providers may want to delay the start of radiation or reduce the dose or area of exposure – particularly in very young children,” said Wong. “But in a study already limiting radiation exposure – patients with these kinds of protocol violations experienced worse outcomes.”

Patients that received radiation therapy treatment according to protocol and within 11 weeks of recovery from stem cell transfusion showed improved overall survival.

About LFCT

This is a blog about CHILDHOOD CANCER and CHILDHOOD CANCER AWARENESS Little Fighters Cancer Trust is a non-profit organisation that offers support and aid to Children with Cancer and their families. When a child is diagnosed with cancer it affects the whole family. One of the parents, usually the mother, must give up their job to care for the child and this creates financial problems for the family. In South Africa especially the majority of these families are not well-to-do; many of them are rural. A diagnosis of cancer can wipe out any family’s finances, let alone a poor family. The costs of special medications, special diets, hospital stays, transport to and from the hospital or clinic and accommodation and food costs for the mother who spends most of the time at her child’s bedside are astronomical. These are the people and problems that fall through the cracks, and these are the people that Little Fighters Cancer Trust has pledged to help in any way possible. LFCT takes a holistic approach to assisting the Children with Cancer and their Families, with the main aim to be the preservation of individual dignity and pride. Little Fighters Cancer Trust also focuses on promotion and advocacy of National Childhood Cancer Awareness in an effort to increase awareness of Early Warning Signs of Childhood Cancer. This would result in earlier diagnosis, giving the Child with Cancer more of a chance at Treatment and Survival. See "About" for more Background info
