Histologically confirmed squamous cell carcinoma (including basaloid-squamous cell and adenosquamous carcinoma) or adenocarcinoma of the thoracic esophagus or the esophagogastric junction (from 5 cm below the entrance of the esophagus into the thorax to the gastric cardia (=esophagogastric junction), types I and II according to the Siewert staging system). Resectable, locally advanced disease (the stage is determined by the combination of CT scan, EUS and PET and by a multidisciplinary team discussion) Age: 18-75 years Health status: WHO performance status (PS) ≤ 1 Patient is considered operable (appropriate organ functions) Adequate renal function: creatinine clearance > 60 mL/min, calculated according to the formula of Cockroft-Gault Adequate pulmonary function: FEV1 > 1.5L or, if < 1.5L at least 75% of the reference value Adequate hepatic function: bilirubin ≤ 1.0 x ULN, AP ≤ 2.5 x ULN, AST ≤ 1.5 x ULN Adequate hematologic values: neutrophils ≥ 1.5 x 109/L, platelets ≥ 100 x 109/L Patient compliance and geographic proximity allow proper staging and follow-up. Women are not breastfeeding, are using effective contraception if sexually active, are not pregnant and agree not to become pregnant during participation in the trial and during the 12 months thereafter. Men agree not to father a child during participation in the trial and during the twelve months thereafter. |
