- Abstract
To elucidate the relationship between del(5q) and the clinical and histological features of small cell neuroendocrine lung carcinoma, 33 tissue samples from patients with this tumor were evaluated. By using fluorescence in situ hybridization, del(5q) was identified in almost 50% of cases (15/33, 45%). Clinically, patients with tumors showing del(5q) were older (mean age = 71 years) with a correspondingly greater pack-year smoking history (mean = 61) than patients with tumors (mean age = 59 years, mean pack-years = 44) without del(5q). Histologically, tumors with del(5q) had a greater frequency of spindle cell morphology (11/14 [79%] vs 6/16 [38%], P < .025) than those without del(5q). This is the first study to find an association between del(5q) and tumor histology in small cell neuroendocrine lung carcinoma.
