Cytogenetic changes in large-cell NEC cell lines.

Abstract

<p>DNA was isolated from the cell lines, primary tumors (PT) and hepatic or lymphatic metastases (M) and genetic aberrations were analyzed by aCGH analysis. Amplitudes over the midline reflect chromosomal gains, amplitudes under the midline losses. M I and M II represent the atypically resected liver metastases of the gastroesophageal NEC.</p
