Comparative Marker Assessment in Small Cell Lung Cancer with Good and Poor Prognosis
Introduction: Small cell lung cancers (SCLC) are highly aggressive and poorly differentiated neuroendocrine neoplasms which comprise ̴̴̴15 % of all lung malignancies.
Aim(s): In a panel of patients with diagnosed SCLC with poor and good prognosis we investigated the prognostic impact by analyzing protein and mRNA expression levels of 9 molecular markers. Furthermore we studied the influence of therapeutic interventions on the prognosis.
Materials and methods: Formalin-fixed, paraffin-embedded tumor samples of 27 SCLC patients with good prognosis (survival ≥ 30 months) and 19 patients with poor prognosis (survival < 30 months) were analyzed for the receptors SSTR1, 2A, 3, 4, 5, CXCR4 and the proliferation markers Ki-67, TOP2A and RacGAP1 by means of immunohistochemistry and RT-qPCR.
