Castleman Disease Collaborative Network

Quest would not have been possible without the incredible support of our sponsors.

Thank you to every organization, family and partner who helped make this event such a success for our community. Your support created opportunities for connection, education, advocacy, and community throughout the entire event.

We’d also like to extend a very special thank you to Rare Diseases, our headline sponsor, for your partnership, generosity, and commitment to this work. Your support played a major role in bringing Quest to life and is a constant reminder that we are stronger together! 💙

Still riding the energy from such an inspirational night!

What an unforgettable experience bringing together advocates, community members, partners, and leaders all in one space. From meaningful conversations to inspiring moments on stage, Quest for a Cure reminded us exactly why this community matters so much.

Thank you to everyone who showed up, shared their stories, supported the Ruxolitinib trial, and made this event so special.

We are stronger together. 💙

Castleman disease can be difficult to recognize because its symptoms often overlap with other conditions.

Understanding the signs and how the disease is diagnosed can help patients and physicians identify it sooner.

If you or a loved one has been diagnosed with Castleman disease, or are still searching for answers, the CDCN community is here to help.
