Radiation Treatment in Children with Glioma Tumors Linked to Increased Death Rates

Radiation Treatment in Children with Glioma Tumors Linked to Increased Death Rates | Cancer - Advances, Knowledge, Integrative & Holistic Treatments | Scoop.it
Almost 90 percent of children treated for low-grade gliomas are alive 20 years later and few die from the tumor as adults. However, children whose treatment included radiation had significantly lower long-term survival rates.
Graham Player Ph.D.'s insight:

Gliomas are the most common brain tumors in children. The tumors start in the brain or spine and are categorized according to their grade. Low-grade gliomas are benign, yet may recur and become high-grade malignant tumors.

A study of the long-term survival of children treated for low-grade gliomas found that almost 90% are alive 20-years later and that few die from the tumor as adults. However, children who received radiation as part of their treatment had significantly lower long-term survival rates than children who were not radiated.

The study's senior author, Peter Manley, MD, of the Brain Tumor Center at Dana-Farber/Boston Children's commented that survival of low-grade glioma in childhood means you are not likely to die of that tumor as an adult, unless radiation has been administered.

CT Scans, Children, and Cancer Risk

CT Scans, Children, and Cancer Risk | Cancer - Advances, Knowledge, Integrative & Holistic Treatments | Scoop.it
Over the last two decades CT scans in children have skyrocketed and the radiation from the CT procedures could result in thousands of future cases of cancer, according to a large, multi-center study published Monday.
Graham Player Ph.D.'s insight:

CT scans in children have increased considerably over the past 20 years. Between 1996 and 2006 CT scans in children under age 5 nearly doubled, while they almost tripled in kids aged 5 to 14 years, according to the report in JAMA Pediatrics.

CT scans are a great tool that should be used wisely after careful consideration of other safe diagnostic procedures. Bear in mind that radiation exposure is accumulated in the body throughout a lifetime.

Overuse of Radiation for Prostate Cancer Patients?

Overuse of Radiation for Prostate Cancer Patients? | Cancer - Advances, Knowledge, Integrative & Holistic Treatments | Scoop.it
Just one session is needed for effective pain relief, but many men get 10, according to researcher
Graham Player Ph.D.'s insight:

In some cancers, such as prostate, lung and breast cancer, the cancer may spread to the bones. Once cancer advances to invade the bones, radiation therapy is usually used to ease the pain it causes. Studies have shown that a single-session radiation treatment is enough for most patients.

However for older U.S. men with prostate cancer, researchers report in the Oct. 9 issue of the Journal of the American Medical Association that single-session treatments were done in only about 3% of men receiving radiation for prostate cancer that had spread to the bones, and more than 50% of the patients went through more than 10 radiation treatments.

The low rate of single treatment is surprising, said Dr. Colleen Lawton, a radiation oncologist who chairs the board of directors for the American Society for Radiation Oncology. Lawton said there are some cases where patients might need 10 or more treatments -- such as when the cancer has spread not only to the bones but also to the nearby soft tissue. But that would be only about 10% of patients. That would not explain the 50% in this study.

So one wonders, if the single-session treatment is the standard of care, then why does this seem not to be the case in practice. Of course doctors do get paid per treatment.
