The optimal treatment for localized squamous cell cancer of the oesophagus is controversial.
For stages IIB, III and IVa, the general consensus currently is for trimodal therapy (i.e., three different treatments). This consists of preoperative chemo and radiotherapy followed by surgical resection, if that is possible.
For early stage cancer (Stage 1, IIA), surgery is the best option and the benefit of preoperative chemoradiotherapy is less clearcut.
You should feel free to discuss all these options with your oncologist and thoracic surgeon.
