North Carolina ? A North Carolina high schooler beat out 1,600 others nationwide to win a $100,000 scholarship Tuesday for developing a model she used to identify stage II colon cancer patients at a high risk for recurrence.

The model created by Shivani Sud, 17, also focused on identifying what may be the most effective drugs for treatment for those with a high risk of recurring tumors, according to organizers of the annual Intel Science Talent Search.

Sud, a senior at Jordan High School in Durham, was named the winner of the competition at an awards banquet in Washington, D.C., where 40 finalists have been showing their projects in competition for top honors.

Sud developed a 50-gene model for predicting recurrences of stage II colon cancer, in which the cancer has spread into nearby tissue. She identified genetic markers that allowed her to characterize various types of tumors.
