Sirolimus (with albumin) injection is used to treat a certain type of epithelioid cell tumor (soft tissue cancer that can form in any part of the body) that has spread to nearby tissues or to other parts of the body or can not be removed by surgery. Sirolimus is in a class of medications called kinase inhibitors. It works by blocking the action of the abnormal protein that tells the cancer cells to multiply. This may help slow the growth of tumors.
