OS and DFS curve analysis performed according to CD117/c-kit immunoreactivity in 88 adenocarcinoma of the lung. Patients with positive (≥5%) membrane decoration exhibited significantly lower OS (a) and DFS (b) rates as compared to patients with negative (<5%) tumors. Moreover, evaluation of survival by immunostaining pattern suggested a trend for decreasing OS (c) and DFS (d) in patients with tumors expressing both positive (+) patterns as compared with patients having either or both negative (−) patterns.
