Patrick Swayze has had an "excellent" response to treatment for pancreatic cancer, the actor and his doctor said Tuesday.
"We're thrilled and grateful for the positive response Patrick has shown towards his treatment," the Dirty Dancing
star and wife Lisa Niemi tell PEOPLE.
"Also, we can't help but feel that all the prayers, meditations and good thoughts sent his way by everyone has made a difference. Thank you!" said the couple.
His physician, Dr. George Fisher, added: "Patrick Swayze continues to respond well to his treatment for pancreatic cancer. Because of his excellent response, he will continue the same therapy at Stanford."
Swayze, 55, announced last month
