Typographical Errors. Because of a printer output problem, errors occurred in the typesetting of some symbols in the article titled "Serum Carcinoembryonic Antigen Concentration Doubling Time Correlates With Tumor Biology and Life Expectancy in Patients With Recurrent Gastrointestinal Carcinoma" (1997;132:188-194), published in February. The errors appear in Tables 3 and 6 on page 192 and are as follows: in the last column of both tables, the expression ">1.00" should read "≈1.00"; in Table 6, first column, the expression "pN2;" should read "pN2∼" and "≥2.7 C\" should read "≥2.7∥"; in the third footnote, the beginning symbol should be a double dagger (not a dagger) and in the same footnote, "pN2;" should read "pN2∼"; and the last footnote's beginning symbol should be a parallel sign (not a back slash). The journal regrets these errors.
