Cancer patients with previously incurable tumors have received hope through life-prolonging treatment that can double the length of time a person can live without cancer.
The new global medical trial involving the Beatson Cancer Center in Glasgow has uncovered high-precision radiation therapy that can extend the life of a patient over one year old.
Patients who had been diagnosed with metastatic tumors – a cancer that had spread to other parts of the body – were considered incurable, but clinical trial researchers found that radiotherapy aggressive could significantly increase life expectancy.
Hailing research as a "game changer," scientists have prescribed to a hundred cancer patients from Scotland, Canada, the Netherlands and Australia "significantly higher doses of radiation." In areas where their cancerous tumors had spread.
Patients receiving the treatment, called ablative stereotactic radiotherapy, lived an average of 13 months longer.
Dr. Stephen Harrow, a researcher at the Beatson West Cancer Research Center in Scotland, and co-author of the study, said, "We are very pleased with these results and I am confident that this could change gives it for a lot.
"Traditionally, when a cancer had spread to other organs than the site of the disease's origin, patients were considered incurable.
"However, there is a theory called oligométastatique theory: according to which a patient recovers only a few points of cancer, they can be eliminated by radiotherapy or surgery to improve their survival. But this has never been shown in a randomized trial before now. "
The 99 patients included in the trial had all previously been treated for cancer and had returned with tumors appearing in five different locations.
The study, published in the Lancet, was developed by Dr. David Palma, a clinical researcher at the Ontario Institute for Cancer Research, and used a number of cancer patients in Scotland.
Dr. Harrow added, "Scottish patients have been fortunate to participate in this innovative clinical trial and we have now been able to show that, if a patient's cancer has spread that ## 147 ## In a few places, tumors can be targeted with high-dose radiation, which has been shown to increase the median survival by 13 months. "
Albert Anderson, 83, originally from Dunure in Ayrshire, was diagnosed seven years ago with a cancerous lesion on the trachea, followed three years later by two small lung tumors.
After receiving treatment as part of the study, Anderson said, "With the test, my cancer has been completely eradicated.
"My treatment was excellent, just excellent. I still go to Dr. Harrow's clinic: first every three months, then every six months. They now only need to see me once a year, which is good and I feel good.
"I hope that the treatment that this trial brings will become normal for everyone and will bring hope to those with secondary cancers."
