ALDH1 expression predicts outcome in node-negative rectal cancer By Kirsty Oswald, medwireNews Reporter Expression of the tumor stem cell marker aldehyde dehydrogenase 1 is an independent predictor for poor prognosis in node-detrimental rectal cancer, experts say. And also being connected with shorter survival, the results claim that ALDH1 expression in rectal cancer cells may predict resistance to radiotherapy and chemotherapy.After randomization, all trial participants were to undergo PCI according to their randomized assignment. The timing of the index PCI treatment depended on individual case acuity, the need to perform PCI on a different day time than the check out to the catheterization laboratory to minimize procedural risk , and scheduling and transportation constraints, but the procedure was to be performed as as possible for each participant soon. All treatments, products, and drugs had been administered and laboratory research carried out regarding to routine practice; no specific PCI process was prescribed. Nevertheless, the use of cutting balloons was limited to in-stent restenosis and atherectomy products were not permitted at hospitals without on-site cardiac surgery.
