Disproportionately low U.S. research funding targets gynecologic cancers

 

Key clinical point: The National Cancer Institute underfunds gynecologic cancer research.

Major finding: Ovarian cancer research funding averaged $97,000 per year of life lost per 100 new cases, compared with $1.8 million for both breast and prostate cancer.

Study details: A review of U.S. data collected by the National Cancer Institute during 2007-2014.

Drops in research funding link with worsening outcomes

The data reported by Dr. Spencer and his associates are very sobering. They present an elegant analysis that documents a lag and decline in funding for gynecologic cancers that factors in the lethality of various cancers. By several other measures as well, funding for research into gynecologic cancers has been slipping in recent years. During 2011-2016, we saw a 90% drop in enrollment into U.S. clinical trials for gynecologic cancers, and from a peak in 2012-2016 the total number of trials for gynecologic cancers fell by more than two-thirds.

These cuts in research funding appear to be having a clinical impact. U.S. data from 2010 to 2014 show a 2% annualized rise in deaths from uterine cancers in contrast to falling mortality rates for several other cancers (CA Cancer J Clin. 2017 Jan;67[1]:7-30). What we are now seeing are the consequences of underfunding gynecologic cancer research.

REPORTING FROM SGO 2018

– The National Cancer Institute is woefully underfunding gynecologic cancer research, compared with several other cancer types, when the money the institute is spending annually is factored by the incidence and lethal impact of each cancer using U.S. data from 2007 to 2014.

That period featured “systematic and pervasive underfunding of gynecologic cancers in relation to other cancer sites,” Ryan J. Spencer, MD, said at the annual meeting of the Society of Gynecologic Oncology. The trends over the period he studied worsened with time and pose the risk that progress in gynecologic cancers – uterine, cervical, and ovarian – will “lag behind” other cancers’ progress in prevention, treatment, and improved survival, said Dr. Spencer, a gynecologic oncologist at the University of Wisconsin–Madison.

To quantify the funding challenges that these three gynecologic cancers have experienced, Dr. Spencer and his associates first calculated a lethality factor for them and 10 other cancer types based on 2014 incidence and mortality data from the Surveillance, Epidemiology, and End Results database maintained by the National Cancer Institute. For example, ovarian cancer had a mortality-to-incidence ratio of 0.636. They then multiplied this by the average person-years of life lost from death attributable to ovarian cancer, 17.5 years, which calculated to about 11 years of life lost for each new case, or 1,100 years of life lost for every 100 new cases of ovarian cancer. Finally, they used this calculated value for each cancer type to divide the amount of money spent by the NCI each year during 2007-2014 to fund research into each of the 13 cancer types to derive an amount spent per year of life lost per 100 new cases, a statistic Dr. Spencer called the funding-to-lethality score.

Annual NCI research funding by cancer site, 2007-2014
In 2014, the NCI alloted about $92 million for research funding for ovarian cancer, which resulted in a funding-to-lethality score of about $83,000 per year of life lost per 100 new cases. When averaged for the entire 2007-2014 period, the funding-to-lethality score for ovarian cancer was $97,000 per year of life lost per 100 new cases, $87,000 for cervical cancer, and $57,000 for uterine cancer. These levels ranked these cancers as numbers 9, 10, and 12, respectively, in the standings for NCI research dollars spent relative to lethality. In contrast, prostate and breast cancer stood at the top of the list, with funding-to-lethality scores of $1.8 million each, followed by melanoma with a funding-to-lethality score of $519,000 per year of life lost for every 100 new cases. The lowest-funded cancer, in thirteenth place, was testicular, with $44,000 per year of life lost per 100 new cases.

Additional time trend analyses showed that the annual funding-to-lethality score for each of the three gynecologic cancers declined during the period studied.

“We must do everything we can to reverse these trends,” Dr. Spencer concluded.
