In-Human CXCR4 Imaging of Hematologic and Solid Tumors Using [68Ga]-Pentixafor-PET

This study is using a specialized PET scan (called Pentixafor-PET) to image tumors in people with blood cancers or solid tumors. The scan targets a protein called CXCR4 that appears on the surface of many cancer cells, potentially helping doctors see where the cancer is more clearly than standard scans. **You may be eligible if...** - You are a patient at Memorial Sloan Kettering Cancer Center (MSKCC) - You have a blood cancer such as certain lymphomas, multiple myeloma, or a related condition, OR you have a solid tumor such as lung cancer, meningioma, or adrenal gland tumor - You are 18 or older - If you are a woman who could become pregnant, you have a recent negative pregnancy test **You may NOT be eligible if...** - You are breastfeeding - You have a history of kidney problems (eGFR < 30) - You refuse participation or decline consent Talk to your doctor to see if this trial is right for you.
