LOS ANGELES - Actor Martin Milner is seeking the public's help in finding a bone marrow donor for his leukemia-stricken daughter.

Milner, who starred in the TV series "Route 66" and "Adam 12," said a marrow transplant may be the only hope for Amy Milner, and locating a match requires widespread blood testing.

Amy Milner, 45, a single mother who lives in Encinitas in San Diego County, was diagnosed with acute myeloid leukemia in February 2003.

"It was right out of the blue," said Martin Milner. "She had no suspicions there was anything wrong with her when she went in for a regular checkup."

The disease, which Milner called one of the more virulent types of leukemia, was treated with chemotherapy and seemed to be in remission for several months. But it returned, he said.

Amy, who has an 11-year-old son, visits the hospital every other day for blood work and, if needed, transfusions. Milner and his wife, Judy, live nearby in Carlsbad and take her in for treatment.

Blood drives to find a match are scheduled in San Diego and Carlsbad this month and one is set for the Screen Actors Guild in Los Angeles on July 16. Kent McCord, Milner's friend and "Adam 12" co-star, is heading the SAG drive.

A donor was not found among family members or on the national registry, said Milner, adding that the effort for his daughter probably will help others.

"There's a good likelihood that somebody else could be saved, somebody not related to us at all. … There are a lot of people waiting for good news," Milner said.

Amy remains "very upbeat," he said. "She really feels like it's going to work, they're going to find a match and she'll be cured."
