Tony Perri, the President of The Darren Daulton Foundation, posted an update on the foundation's website Wednesday afternoon.
"He has returned to his Clearwater area home to continue recuperating amongst his immediate family and friends," Perri writes.
Daulton, 51, will begin treatments in Florida.
A Glioblastoma is the most common and most aggressive malignant brain tumor. They typically spread quickly with tentacle-like projections.
On July 1st, neurosurgeon Dr. Kevin Judy at Thomas Jefferson University Hospital said the surgery to remove two tumors was successful. It was a delicate procedure as one of the tumors was in the language area of the brain.
Dr. Judy said then even if the tumors are completely removed, there can still be malignant cells left behind, so Daulton will likely also need radiation.
Standard protocol for Glioblastoma is surgery followed by oral chemotherapy along with radiation. However there is no cure.
Even with treatment, the average survival time is 15 months.
If most of the tumor is able to be removed during surgery, patients typically stay healthier longer.
The statement goes on to say, "Darren and his family wish to thank everyone for their loving support throughout this difficult time. He is deeply touched. In typical fashion, he again said, 'Right on; Fight on.'"
The September 9th golf tournament that benefits the Foundation will continue as planned at the urging of Daulton, Perri says.
A 3-time All Star, Daulton played 14½ of his 15 seasons with the Phillies and was a key part of the NL championship team in 1993. He finished his career with the 1997 World Series champion Florida Marlins.
