Summary

The objective of the TransValid-KFO179/GRCSG-Trial-A is the validation of potential biomarkers. These are predictive (Prediction of probability of response to a certain therapy) / prognostic (predicting long-term outcome) microarray-based gene expression signatures and immunohistochemically evaluated biomarkers. The evaluation was done within the KFO179 (www.kfo179.de) - the validation is implemented in this trial.

Therefore tumor material of patients undergoing standard radiochemotherapy will be analyzed from pretreatment biopsies an residual tissue from the resection specimen after surgery. This validation and the biomaterial asservation will be incorporated into clinical routine in all participating centers as a model for the treatment of solid tumors. The obtained biomarkers with a predictive and prognostic power will be used to develop an algorithm to predict patients at high risk of local and distant cancer recurrence.

Translational Research and multimodal treatment

Blood/biopsy samples (tumor \& mucosa) are taken pretherapeutically. Blood samples (serum \& plasma) are drawn at 11 time points during RCTx (e.g. for analysis of 5-FU metabolism, genomic DNA extraction). After pathohistological workup of the TME specimen, the formalin-fixed material will be transferred to the central biobank of KFO179. Blood samples (plasma \& serum) will be drawn during 5y-follow-up. Treatment (based on CAO/ARO/AIO-94- and CAO/ARO/AIO-04-phase-III trials of the GRCSG): Preoperative RCT: 28x1.8 Gy (total: 50.4 Gy, 5 fractions per week on d1-d38) combined with 5-FU (1000 mg/m2/d) as 120 h civ during 1st and 5th week. TME-surgery is performed 6 weeks after RCTx. 4 to 8 weeks after surgery, patients receive either 4 cycles 5-FU (500 mg 5-FU/m2 iv, d1-5, repeat d 29-33) or 3 cycles (6 single appl.) of FOLFOX regimen \[(400 mg FA/m2, 2-h civ, d 1; 100 mg oxaliplatin/m2, 2-h civ in 500 ml Glucose 5%, d 1; 2400 mg 5-FU/m2 as 46-h civ) on d1+d15, d30+d45 and d60+d75\].
