Cancer Drug Trials Often Halted Early An increasing number of clinical trials for new cancer treatments are being halted before the risks and benefits have been fully evaluated， say Italian researchers， who warn that this growing trend could put patients at risk of harm from new therapies rushed into use.

When we analyzed 25 trials over a 10-year period between 1997 and 2007， we found a consistent increase in prematurely stopped trials - more than 50 percent were stopped within the last three years， study co-author Giovanni Apolone said at a news conference Tuesday. |
