BACKGROUND: Lung cancer stem cells (CSCs) are considered to be the seed of lung cancer, and CD133 is a marker of lung CSCs. Here, we developed gefitinib-loaded poly(ethylene glycol) 2000-distearoylphosphatidylethanolamine nanomicelles with CD133 aptamers (M-Gef-CD133) to eliminate CD133(+) lung CSCs. METHODS: M-Gef-CD133 was prepared using a lipid-film-based approach. The targeting and activity of M-Gef-CD133 towards lung CSCs were evaluated. RESULTS: M-Gef-CD133 were small (25 nm) and showed enhanced cytotoxic effect towards CD133(+) lung CSCs compared with non-targeted M-Gef and gefitinib...

BACKGROUND: The role of colonoscopy in the screening of colorectal cancer (CRC) has been unequivocally established. In Germany, screening colonoscopy with full insurance reimbursement is available for individuals aged 55 and above, and/or for persons with well-known risk factors for CRC. However, advanced CRC is not uncommon in individuals below 55 years. This study was designed to investigate the incidence of advanced CRC in patients < 55 years. METHODS: A retrospective analysis of data from a prospectively maintained CRC database of a university hospital in Germany was performed...
