The ongoing federal shutdown in the United States could block care, including last-ditch clinical trials for treatment, for hundreds of cancer patients, many of whom include children, a National Institutes of Health spokesman told the AFP.
About three quarters of the staff at the NIH, which operates the largest research hospital in the world, has been placed on unpaid leave indefinitely.
While the NIH Clinical Center is continuing to treat patients, it is operating at "roughly 90 percent of normal patient load," said an agency memo.
That means about 200 patients will be turned away from treatment at the Clinical Center each week the shutdown persists, including about 30 children, a spokesman told AFP.
About 10 of those children have cancer, he added.
There are some 1,400 clinical trials ongoing at the NIH center, and four new ones ready to start next week will have to be postponed until the government resumes work, he said.
"Just to be clear, we aren?t turning patients away permanently -? we would be delaying their admission, since we are not enrolling new patients at this time," spokesman John Burklow said in an email.
The NIH has furloughed 14,700 employees, but more than 2,500 staff are staying on to manage patient care, said the agency memo.
The Clinical Center is a place where patients are admitted "only when standard medical treatments have failed, and other treatment options are not available. As a result, they have no other alternatives," the memo said.
Some 800,000 federal workers across the US capital region and beyond have been told to stay home from work without pay, in the first US government shutdown in 17 years.
The shutdown came after Democrats refused to give in to Republican lawmakers' demands for a rollback of President Barack Obama's healthcare reform law, which Congress passed in 2010 and was subsequently upheld by the Supreme Court.
