GOOD MORNING: The sad news divulged Wednesday that Ryan O’Neal has leukemia is encouraged by good news in the fight against breast and ovarian cancer. “Because of Hollywood, we have a new treatment,” Lilly Tartikoff told me. Through the research funded by the Revlon UCLA (and Hollywood!) team, Lilly says herceptin was created by Dr. Dennis Slamon as the first nontoxic treatment for breast cancer. “It was a collaboration among Hollywood, science and Ron Perelman,” Lilly reminds. It took the efforts of the entire world for the first nontoxic new prescription. It has been tested globally — it is that big an effort. Lilly also enumerated upcoming events she will be heading. Starting Saturday, the Revlon Run/Walk for Women begins in Times Square (42nd Street closed for the start) and winding up in Central Park, where Kristin Davis hosts a program including Queen Latifah, Halle Berry and Karen Duffy. Lilly returns to L.A. for the May 12 Run/Walk winding up in the L.A. Coliseum, with Dylan McDermott as host, Megan Mullally singing “Amazing Grace,” Karen Duffy and Melanie Griffith as Revlon spokespersons. Perelman co-chairs with Tartikoff the Revlon/UCLA Women’s Cancer Research Program. Lilly then wings to Monaco for the QVC “Cure By The Shore” live show under the patronage of Prince Albert. It airs May 19 (4 p.m. ET) benefiting the National Women’s Cancer Research, with an expected sale of over a million $ in sunglasses and other items; Sela Ward again hosts. With the QVC in Monaco “next door to Cannes,” Lilly says, “it will be like a home away from home for us.” Lilly’s teamed with Lisa Paulsen and the Entertainment Industries Foundation in all these efforts.MIRAMAX DID NOT KNOW about Ryan O’Neal’s leukemia as of Wednesday, when his condition was revealed.
