we conclude that ( a ) mixed sclc-non-sclc differentiation is frequent and can be assessed by immunohistochemistry , ( b ) neuroendocrine differentiation in non-sclc is mainly observed in poorly differentiated tumors and in advanced clinical stages , and that ( c ) this heterotopic phenotype is correlated with aneuploidy and has clinical implications .
