Due to a typesetter's error, the incorrect version of the thirdparagraph from the end of "Tamoxifen Pharmacogenetics MovesCloser to Reality" (Vol. 97, No. 6, p. 412) was printed. Thefourth sentence should read as follows: "He points out thatthe response rate for Herceptin (trastuzumab) is only 25%, evenfor patients with multiple copies of the Her-2/neu gene."
