Stage III cancer of esophagus
would mean that the the cancer has progressed beyond the wall of the esophagus and nearby lymph
nodes to surrounding tissues, but other organs are not yet affected. Usually for this stage III, chemotherapy
and radiotherapy are the main stay of treatment. However some oncologists also prefer to combine this with curative surgery which follows chemo-radiation
therapy,however the risk from such surgeries is quite high at this stage. Chemotherapy along with radiotherapy alone has shown a survival rate
of 3-5 years for around 30 percent of the stage III patients. Therefore the survival would depend on overall factors including the form of treatment. Hope this will answer you in someway. Regards.
