摘要: Small cell lung cancer (SCLC) is distinguished by excessive numbers of circulating tumor cells (CTCs) in extended and recurring disease. This malignancy has a poor prognosis due to rapid emergence chemoradioresistant relapses after first-line chemotherapy. In vitro expansion several CTC lines allowed for detailed study the contribution these metastasis. Generation CTCs involves establishment co-cultures recruitment macrophages specific cytokines. All show E-cadherin-positive epithelial-like spontaneous assembling into very large tumorospheres. Such multicellular aggregates seem be responsible observed broad resistance limited access drugs, quiescent layers, hypoxic cores.
