HemOnc.org: A Collaborative Online Knowledge Platform for Oncology Professionals.
OBJECTIVE
Cancer care involves extensive knowledge about numerous chemotherapy drugs and chemotherapy regimens. This information is constantly evolving, and there has been no freely available, comprehensive, centralized repository of chemotherapy information to date.


METHODS
We created an online, freely accessible, ad-free, collaborative wiki of chemotherapy information entitled HemOnc.org to address the unmet need for a central repository of this information. This Web site was developed with wiki development software and is hosted on a cloud platform. Chemotherapy drug and regimen information (including regimen variants), as well as other information of interest to hematology/oncology professionals, is housed on the site in a fully referenced and standardized format. Accredited users are allowed to freely contribute information to the site.


RESULTS
From its inception in November 2011, HemOnc.org has grown rapidly and most recently has detailed information on 383 drugs and 1,298 distinct chemotherapy regimens (not counting variants) in 92 disease subtypes. There are regularly more than 2,000 visitors per week from the United States and international locations. A user evaluation demonstrated that users find the site useful, usable, and recommendable.


CONCLUSIONS
HemOnc.org is now the largest free source of chemotherapy drug and regimen information and is widely used. Future enhancements, including more metadata about drugs and increasingly detailed efficacy and toxicity information, will continue to improve the value of the resource.
