For Physicians
The Clear Cell Sarcoma Foundation is committed to helping bring together physicians knowledgeable about Clear Cell Sarcoma. We want to partner with physicians to offer support and connection with other physicians as well as CCS patients. Since CCS is ultra-rare, it is difficult to access up-to-date information quickly. CCS patients and caregivers have participated in FDA listening sessions, Focus Groups and Industry webinars. CCS is our main focus so please reach out to us, we are here for you.

Clear Cell Sarcoma Physician Resources
Clear cell sarcoma (CCS) is an ultra-rare cancer with no established standard of care and limited clinical trial data. To support oncologists and researchers, the Clear Cell Sarcoma Foundation has developed a series of concise, literature-based resources of available treatments and disease features.
These include a new summary of the 2025 Ibero-American Consensus for the Management of Liver Metastases of Soft Tissue Sarcoma, providing international guidance relevant to CCS cases where the liver is a site of metastasis.
In addition, a detailed white paper provides a comprehensive review of chemotherapy use in CCS.
Surgery remains the standard of care for CCS and offers the best chance for durable disease control whenever possible. Systemic therapies may be considered when surgery is not feasible, when clear margins are not achieved, or in the setting of metastatic disease, but to date they have shown only limited effectiveness.
Disclaimer: The Clear Cell Sarcoma Foundation provides summaries of published evidence and expert consensus for educational purposes. These materials do not constitute medical advice, clinical directives, or treatment recommendations. Clinical decisions should be made based on each patient's individualized circumstances, the treating clinician's judgement, and current standards of care.

Quick Reference Summaries
Expanded Resource
This white paper is an evidence-based review of chemotherapy in CCS that examines available data on outcomes and harms, explains why chemotherapy persists despite limited efficacy, and details the ethics of informed consent. It provides practical information to support decision-making for clinicians and patients while recommending steps toward disease-specific treatment guidelines and expanded access to more appropriate alternatives.
Here are the Clinical Trials from National Institute of Health focused on Clear Cell Sarcoma. SARC (Sarcoma Alliance for Research through Collaboration) will occasionally post active trials on CCS as well.
