Nobody should beat cancer
only to die from the cure.

Holly Patz's vow was to do everything she could to advance research into treatments and a cure for lung Graft-Versus-Host Disease (GVHD), known as Bronchiolitis Obliterans Syndrome (BOS) — a rare, highly morbid condition that occurs after an allogeneic bone marrow transplant. Ten to fifteen percent of all blood cancer patients who receive such a transplant will develop BOS, which lacks treatment and is ultimately fatal.

"Her animating wish was to find a cure for BOS to ensure that others did not have to suffer the way she did."

Holly beat blood cancer with a successful bone marrow transplant but later developed BOS and died in the hospital thirteen months after receiving a lung transplant. During the decade she fought BOS, she never refused an opportunity to participate in clinical trials or otherwise advance knowledge about lung GVHD.

The Mission

Holly's Vow is her legacy — a fund to provide hope for those affected by lung GVHD. Our objective is to become a key funding source for research into treatments for BOS, as well as a clearinghouse for the best research in this field. Despite its morbidity and high mortality, research into BOS is severely underfunded. We are committed to changing that.

Holly's fight should be celebrated. Nobody should beat cancer only to die from the cure. Please join us in carrying out Holly's Vow.

About BOS

Bronchiolitis Obliterans Syndrome is characterized by progressive narrowing of the small airways, leading to worsening shortness of breath, recurrent respiratory infections, and ultimately respiratory failure. Its estimated five-year survival rate is approximately 40%.

BOS often develops insidiously and may initially be mistaken for general post-transplant debilitation, resulting in delayed diagnosis. By the time it is identified, irreversible lung damage in the form of fibrosis has often already occurred. There are currently no reliably effective treatments.

Current research — including work at Stanford's Lung GVHD Clinic — is focused on improving early detection and developing novel therapeutic strategies to improve long-term outcomes in bone marrow transplant recipients. Learn more about the disease →
