[Updated: 2:15 pm Pacific, 12/8/09 with larger fundraising numbers from this year’s gala.] The Fred Hutchinson Cancer Research Center, the Seattle-based nonprofit, said it raised $8.85 million at its annual Hutch Holiday Gala on Saturday night. Most of the money, $7.95 million, was directed toward research to boost people’s immune systems to fight cancer cells. The effort was sparked by the parents of Amazon.com founder Jeff Bezos, who agreed to pledge $10 million last month to the immunotherapy effort. The center raised $2.2 million at last year’s fundraiser.
