Stage IV adult primary liver cancer
Stage IV is divided into stage IVA and IVB. In stage IVA, there is more than one tumor, which may have spread to nearby lymph nodes, and the tumors (1) are in both lobes of the liver; or (2) are affecting a major branch of blood vessels in the liver; or (3) have spread to nearby organs (besides the gallbladder); or (4) have broken through the lining of the peritoneal cavity. In stage IVB, the cancer has spread beyond the liver to other places in the body. The tumors may be of any size and may have also spread to nearby blood vessels and lymph nodes.
