Note that the frequency of EGFR mutation in the unselected U.S. patients 1 of 61 appears to be low when compared with the frequency of reported gefitinib response at 10.4%. This difference has a modest statistical significance ( P = 0.025 by the chi-square test). Thus this result could still be due to chance to a fraction of responders who do not have EGFR mutations or to failure to detect EGFR mutations experimentally in this tumor collection. If the frequency of EGFR mutation in gefitinib-responsive U.S. patients (5/5) is compared with the expected frequency of gefitinib response (10.4%) the chisquare probability is again less than 10 –12 .
