An old chemotherapy drug used to kill leukemia may have the ability to help cure cancer, according to University of Missouri researchers.  

Update at 3:05 ET: The Connecticut Supreme Court ruled unanimously Thursday afternoon that the state can require Cassandra to continue treatment.

Her mother, Jackie Fortin, said she's disappointed by the decision. "She knows I love her and I'm going to keep fighting for her because this is her decision," Fortin said. "I know more than anyone, more than DCF, that my daughter is old enough, mature enough to make a decision. If she wasn't, I'd be making that decision."
