Abstract: The present invention provides an anti-cancer agent comprising anti-glypican 3 antibody wherein the anti-cancer agent is administered after a cancer treatment, Preferably, after a cancer treatment is after a treatment for liver cancer, and the treatment for liver cancer is in particular a resection of liver cancer cells. The anti-cancer agent according to the present invention is preferably administered if glypican 3 is expressed in the resected liver cancer cells. The anti-glypican 3 antibody is preferably a monoclonal antibody. The anti-cancer agent according to the present invention is useful for preventing cancer and for preventing the recurrence of cancer.

Abstract: An anti-glypican-3 antibody comprising one or more amino acid substitutions introduced in the Fc region is disclosed. Preferably, in the anti-glypican-3 antibody, one or more of the amino acid residues at the positions 239, 298, 326, 330 and 332 in the Fc region are substituted with other amino acid residues. Since the Fc-modified anti-glypican-3 antibody of the invention exhibit enhanced ADCC activity, it is useful in treating cancers, such as hepatic cancer. Also disclosed are an anticancer agent comprising the anti-glypican-3 antibody of the invention and a pharmaceutically acceptable carrier, as well as a method of treating a patient with cancer comprising administering to the patient the anticancer agent of the invention.

Abstract: The present invention relates to a scoring system for the prediction of cancer recurrence. More particularly, the present invention concerns with the selection of genes and/or proteins, and generation of formulae with the selected genes and/or proteins for the prediction of cancer recurrence by measuring the expression of genes and/or proteins of human tumor tissues, and comparing their patterns with those of the gene and/or protein expression of human primary tumors from patients who have cancer recurrence and those who do not have cancer recurrence.

Abstract: The present invention relates to a method for identification of enzymes that are preferentially expressed in certain tumor tissue as compared with rapidly growing normal cells or tissue, use of said enzymes for the compound design to generate an active anti-cancer substance selectively in tumor tissue, compounds designed based on said enzymes, their pharmaceutically acceptable salts as well as pharmaceutical composition thereof.
