NCIt definition : A fucosylated derivative of monosialotetrahexosylganglioside (GM1) and tumor antigen
associated with small-cell lung cancer (SCLC). Fucosyl-GM1 is specifically expressed
in SCLC while minimally or not expressed on healthy, normal cells; it plays a key
role in tumor cell proliferation and may be a biomarker to detect the presence of
these cancer cells.;
