"Doctors are used to giving IV chemotherapy, so this is a new skill set in terms of giving the drugs," she said. "It comes with different equipment and patient instructions and side effects. As individual physicians and centers become more comfortable and confident with learning how to manage the side effects, its use will increase."
Dr. Elizabeth Poynor, a gynecologic oncologist at New York City's Lenox Hill Hospital, agreed. "The toxicity and intensity is greater than with IV therapy, so some people can't tolerate it," she said. "But for those who do, survival is clearly benefited."
"It's a tradeoff," Poynor said. "There are more side effects, but there are also survival benefits. You don't know how you will tolerate it until you try -- and if it's not for you, you can back off."
Because this study was presented at a medical meeting, the data and conclusions should be viewed as preliminary until published in a peer-reviewed journal.
