A nonprofit group that supported children's cancer treatment is closing in December.

The Fighting Children's Cancer Foundation is calling it quits after difficulty finding enough people to hold leadership positions in the organization.

Alice Didier, Fighting Children's director, said the nonprofit couldn't find people willing to serve in needed positions, such as secretary and treasurer.

Her son, Clint Didier, a former tight end for the Washington Redskins who ran for U.S. Senate this year, has helped with the Eltopia-based organization's golf tournament fundraisers.

But that fundraiser was facing competition from other charity golf fundraisers, Didier said. "It's getting more difficult to raise money," she said.

The nonprofit still will distribute the $67,500 raised during its eighth annual Celebrity Golf Tournament at Kennewick's Canyon Lakes Golf Course in June.

Didier said $5,000 was donated to Richland's Kadlec Medical Center to help families pay for children's cancer treatment. The rest went to support research across the nation.

The group formed about nine years ago with the goal of supporting kinder cancer treatment for children, Didier said. It was an offshoot of Citizens for Medical Isotopes, a local group that promoted production of medical isotopes.

In addition to supporting research for alternative cures, Didier said the group also has supported research into causes of cancer.
