A Pilot of a Microdevice For In Situ Candidate Drug Screening in Cutaneous Lesions of T-Cell Lymphoma

This study uses a tiny implantable device (a microdevice about the size of a grain of rice) that is placed directly into a tumor. The device releases tiny amounts of multiple different drugs at once, allowing researchers to see which drugs actually kill that specific patient's cancer cells — right inside the body. This could help personalize cancer treatment. **You may be eligible if...** - You have a solid tumor (such as breast, pancreatic, or other cancer) that is accessible for a biopsy or minor procedure - You are scheduled for surgery or a biopsy where the device can be inserted and retrieved - You are 18 or older and able to provide consent **You may NOT be eligible if...** - Your tumor is not accessible for the device insertion procedure - You have certain clotting problems or are on blood thinners that cannot be safely stopped - You are pregnant - You have allergies to any of the drugs being tested in the device Talk to your doctor to see if this trial is right for you.
