title: Esophageal carcinoma: current staging strategies.
abstract: A patient with suspected esophageal carcinoma represents a challenge to the treating physicians. Most patients present with an advanced stage of disease, and in the majority of cases only palliative treatment can be offered. Various treatment modalities are available, which are applied according to the TNM stage of the disease and the performance status of the patient. A precise histological diagnosis and highly accurate tumor staging of a patient with esophageal carcinoma is a prerequisite for the selection of the most suitable treatment option. Endoscopic ultrasound (EUS) has emerged as the most accurate diagnostic modality for locoregional staging. Problems in identifying early tumor stages or tumor strictures can be generally overcome by using miniprobe sonography (MPS). EUS/fine-needle aspiration biopsy (FNA) technology provides a valuable means of identifying suspicious locoregional lymph nodes. Patients with a proximal tumor (trachea bifurcation) should undergo bronchoscopy to rule out infiltration of the tracheobronchial system. Ultrasound (US), computed tomography (CT), and possibly magnetic resonance imaging (MRI) are the diagnostic tools of choice for extended tumor staging. After excluding extended tumor stage and severe concomitant diseases, diagnostic laparoscopy with intra-abdominal ultrasound should be performed in patients with adenocarcinoma of the esophagus prior to esophagectomy. Intra-abdominal metastases which can be missed preoperatively in some cases have to be ruled out in order to avoid unnecessary surgery.
