Zusammenfassung
When preceding surgery, neoadjuvant radiochemotherapy can decrease local recurrence and has become standard treatment modality in specialized surgical centers. However, there is a wide spectrum of tumor responsiveness ranging from complete response to complete resistance. Pre-therapeutic predictors would therefore be of considerable clinical significance for stratification of patients into groups of responders or non-responders of radiochemotherapy. Pre-therapeutic biopsies from 23 locally advanced rectal carcinomas (determined by rectal ultrasound as uT3 and uT4) were analyzed for gene expression signatures usi…
