Todd Allen

Welcome to Todd’s CaringBridge website. We’re using it to keep family and friends updated about his condition. If you know of others who’d like to be kept appraised, please have them email me at and I’ll add them.

Todd has been through so much since a glioblastoma multiformae brain tumor was found in his right parietal lobe on September 21, 2004, just 4 months after we moved into a fixer-upper home in Duvall, WA. After surgery and intensive radiation treatments, he started on a chemotherapy that ended up causing a toxic reaction in his bone marrow. That first chemo was stopped after a year and he began a brand new 2-year course of a different chemotherapy. He also took part in several adjunct therapies that he and his dad researched. Finally, in 2008, after being told in 2004 he had six months to live, he was cancer free and the deadly brain tumor never returned.

He had returned to work full time at AT&T headquarters in Redmond, WA as a specialist in wireless enterprise and emerging technologies within weeks of his surgery in 2004. Seizures caused by scar tissue in the cavity left by the tumor began occurring in 2010. He tried numerous anticonvulsants to control them but had little luck. They either didn’t work well or caused side effects he couldn’t bear. At the very beginning of 2012, as he and son Sidney returned from a trip to Southern California to see one of the last performances of the remaining members of the Grateful Dead, he began to feel very unwell. On January 5th, he was diagnosed with acute myeloid leukemia, caused by that first chemo that had damaged his bone marrow.

Todd was told by his doctors that he needed to have a bone marrow transplant to save his life. He had a 1 in 3 chance of survival: one third of patients in similar situations succumbed to their illness before their transplant was performed, one third didn’t survive the transplant process, and only one third were strong enough to make it through and recover their health. After 3 rounds monthly rounds of chemo to completely destroy his bone marrow and immune system, Todd received bone marrow stem cells from an unrelated male donor in Germany on May 3, 2012.

His road back to health was long and arduous. He suffered the rejection process known as “graft vs. host disease” as his body fought the invading stem cells it was supposed to accept to begin building his new immune system. Because the

the tumor never recurred, but a benign cyst appeared in the same location in 2014 and the surgery to remove it caused Todd to become paralyzed on his left side.

We appreciate your words of hope and encouragement. Thank you for visiting.
