1. A method of treating cancer in an individual in need thereof, the method comprising administering to the individual a therapeutically effective amount of a conjugate comprising (a) an antibody that binds to a tumor-associated cell surface molecule of a cancer cell and (b) a sialidase conjugated to the antibody, whereupon, after administration to the individual, the sialidase cleaves a sialic acid from the surface of the cancer cell, wherein the sialic acid is a ligand for a sialic acid-binding Ig-like lectin (Siglec) receptor, wherein the sialidase is a prokaryotic sialidase or a eukaryotic sialidase.
