The director of the Winthrop P. Rockefeller Cancer Institute at the University of Arkansas for Medical Sciences is resigning, effective July 31.
Dr. Peter Emanuel, 59, gave no reason for his departure in a two-sentence letter of resignation dated Friday and released Monday under the Arkansas Freedom of Information Act.
"Out of primary consideration of my large clinic of patients that their medical care be transitioned to appropriate physicians, my last official day at UAMS will be July 31, 2018," he wrote.
Emanuel declined to say late Monday why he resigned or what his plans are.
"I may be able to comment on why I resigned, but I'm not divulging my future plans just yet," he said.
Emanuel was not asked to resign, UAMS spokesman Leslie Taylor said Monday.
"There were challenges," Emanuel said when asked if his resignation related to recent financial problems at UAMS.
"I'm not going to say if they were financial or otherwise" at this time, he said.
In January, UAMS laid off almost 260 employees to curb an anticipated $72.3 million deficit. Those layoffs included one full-time physician -- a general ear, nose and throat doctor who did not work at the cancer institute, Taylor said.
UAMS also said in January that it was cutting 600 positions but only 258 of them were filled at the time. The eliminated positions represented 5.5 percent of UAMS' 10,900 employees.
Taylor said Monday that no unfilled physician positions were eliminated.
Founded in 1984, the cancer institute later was named after former Arkansas Lt. Gov. Winthrop P. Rockefeller, who died in 2006.
Emanuel is "widely recognized as an expert in leukemia and lymphoma," according to a UAMS website.
His resignation also follows UAMS' decision to shut down its cardiac surgical program temporarily while it searches for another surgeon to replace one who retired in late April.
Dr. Gareth Tobler, the lead cardiac surgeon, made $195,000 annually from UAMS. Taylor said Monday that she has since learned that Tobler also was paid some by the John L. McClellan Memorial Veterans Hospital in Little Rock. She did not have that hospital's salary information late Monday.
