BUFFALO, N.Y. — The doctor treating Hall of Fame quarterback Jim Kelly for cancer says Kelly will start chemotherapy and radiation next week.

The treatment plan was outlined Tuesday by Dr. Peter Costantino of Lenox Hill Hospital in New York City, where the East Brady graduate and longtime Buffalo Bills star is being treated for a sinus cancer.

Costantino says he’s confident the regimen has a good chance of success. If not, he says Kelly’s skull-base tumor remains operable.

Kelly underwent surgery in Buffalo last June to remove cancerous cells from his upper jaw.

The chemotherapy and radiation will target cancer cells in his maxillary sinus and adjacent tissues.
