Conditions

Summary

The goal of this trial is to see if active surveillance monitoring and hormonal therapy in patients diagnosed with ductal cell carcinoma in situ (DCIS), an early stage of breast cancer, can be an effective management of the disease. Participants will be asked to receive control hormonal therapy or an investigational hormonal therapy treatment. Participants will be asked to return for evaluation with MRI at three months and six months. Depending on the evaluation participants will have the option to continue on the treatment. If the evaluation suggests surgery is recommended, the participant will discontinue the study treatment and will undergo surgery. In addition to the treatment and MRI evaluation, participants will be asked to provide blood sample to understand their immune status, provide saliva sample for genetic testing, provide the study with a portion of the tissue or slides generated from tissue removed during surgery performed as part of their standard of care.


Eligibility

Sex: FEMALEMin Age: 18 Years

Plain Language Summary

Simplified for easier understanding

This study (RECAST) is exploring whether active surveillance — careful monitoring without immediate surgery — is a safe option for certain women with DCIS (ductal carcinoma in situ), a very early form of breast cancer where abnormal cells are confined to the milk ducts. **You may be eligible if...** - You are a woman aged 18 or older - You have been diagnosed with hormone receptor-positive DCIS (at least 50% ER or PR positive), with or without very small areas of invasion - If you previously took hormonal therapy (like tamoxifen), you have completed a 4–6 week washout period **You may NOT be eligible if...** - Your DCIS is hormone receptor-negative - You have invasive breast cancer (not just DCIS) - You are currently on hormonal therapy without a washout period Talk to your doctor to see if this trial is right for you.
