Source link A 2016 study conducted by the National Cancer Institute has revealed good news for those affected by brain tumors; survival rates have slowly increased over the past few decades. The study looked at patients diagnosed between 1973 and 2009, and the results showed large improvements in five-year survival rates.
Brain tumors are one of the most serious and deadly forms of cancer. It is estimated that 23,000 Americans are diagnosed with a brain tumor each year, with 12,000 perishing due to the disease. The overall five-year survival rate for those diagnosed with a brain tumor between 1973 and 1998 was 34 percent, with only minor improvement in the rates for those diagnosed between 1998 and 2009. This study showed an increase in five-year survival rates of 3 percent annually; rising to a rate of 44 percent.
The study was conducted by researchers from the National Cancer Institute (NCI), as part of the Surveillance, Epidemiology, and End Results (SEER) program. It is the first study to look at national trends in brain tumor survival since 1973. NCI director Dr. Norman E. Sharpless noted that “In addition to providing vital information about the populations most likely to be diagnosed with each brain tumor type, this research highlights how improved therapies have made a difference for people over time.”
The reason for the increased five-year survival rate is currently unknown; however, the researchers believe that the growth in the use of surgery, chemotherapy, and radiation therapy to treat brain tumors may be a contributing factor. The improved treatment options may be helping to increase the overall life expectancy of those diagnosed with a brain tumor.
These findings provide hope for those affected by brain tumors and a ray of light in an otherwise dark situation. It is important to note, however, that further research needs to be done to determine the reasons for the improved survival rates. This study provides a good starting point and will no doubt pave the way for further research into the treatment and prevention of this deadly cancer.
