Prospective, Open, Multicentre Phase I/II Study to Evaluate the Safety and Efficacy of a Neoadjuvant Radiochemotherapy With Docetaxel and Oxalipaltin in Patients With Adenocarcinoma of the Gastric-oesophageal Junction

Brief Summary

Detailed Description

Radiotherapy starts on day 1 of chemotherapy after the application of Docetaxel and Oxaliplatin and will be administered in single doses of 1.8 Gy once daily and five times a week for 5 weeks. In the sixth treatment week a boost of 3 further radiations with 1.8 Gy will be applied. Simultaneous chemotherapy: Initially, in part A of the study the maximum tolerable dose (MTD) for the simultaneous chemotherapy will be identified with a 3-step dose escalation scheme: Level 1: Docetaxel: 20 mg/m2 Oxaliplatin 40 mg/m2 i.v., Level 2: Docetaxel: 20 mg/m2 Oxaliplatin 50 mg/m2 i.v., Level 3: Docetaxel: 25 mg/m2 Oxaliplatin 50 mg/m2 i.v., The treatment starts with 3 patients in level 1. If no dose limiting toxicities appear, it will be switched to dose level 2. The same applies for the switch from level 2 to level 3. If a DLT appears on one level, a further 3 patients will be treated within this dose level. If in one level at least 2 of 6 patients show DLT, the subjacent level will be defined as the maximum tolerable dose (MTD).
