HAUPPAUGE - A Long Island man who donated 60 percent of his liver to a friend stricken with cancer is suing the hospital where the operation was done.

Dominick Gagliano says doctors at Mount Sinai in Manhattan promised him they wouldn't do the surgery if the cancer had spread beyond his friend's liver.

"They came and got me and told me everything was clean, it didn't spread and they did the surgery," Gagliano says.

Now Gagliano is suing the hospital after his friend died three weeks ago, claiming doctors knew the cancer had in fact already spread at the time of the operation.

A Mount Sinai hospital spokesman wouldn't comment specifically on Gagliano's lawsuit, but said in general that doctors follow national guidelines on transplants and have no reason to violate that policy.
