Often poor as are usually advanced on time of diagnosis therefore resection options are poor. In addition, metastatic rate is high: malignant tumours are locally invasive and metastasis occurs via draining lymph nodes, haematogenous spread to distant areas.

Often poor as usually in advanced stages on time of diagnosis therefore limiting resection options. In addition, metastatic rate is high: malignant tumours are locally invasive and metastasis occurs via draining lymph nodes (Cervical and Prescapular lymph nodes in the cervical oesophagus and Mediastinal in the thoracic oesophagus) and haematogenous spread to distant areas.
