NOVEL MARKER FOR SENSITIVITY AGAINST SULFONAMIDE COMPOUND

摘要

The sensitivity of a tumor cell to a sulfonamide compound or the anti-tumor effect of a sulfonamide compound can be examined by determining the expression level of EGFR1 in the tumor cell and employing the variation in the EGFR1 expression level as a measure. Thus, a method for determination of the sensitivity of a tumor cell to a sulfonamide compound; a method for determination of the anti-tumor effect of a sulfonamide compound; and a test kit for use in these methods are provided.
