Gastroesophageal junction cancer has an increasing in-cidence in western countries. It is inoperable when firstmanifested in more than 50% of cases. So, palliationis the only therapeutic option for the advanced diseaseto relieve dysphagia and its consequences in weakenedpatients with an estimated mean survival under 6 mo.This article has tried to identify trends focusing on cur-rent information about the best palliative treatment,with an emphasis on the role of stenting. Self-expand-ing stent placement, either metal or plastic, is the mainmanagement option. However, this anatomical loca-tion creates some particular problems for stent safetyand effectiveness which may be overcome by properlydesigned novel stents. The stents ensure a good qual-ity of life and must be preferred over other alterna-tive methods of loco-regional modalities, i.e., externalradiation, laser thermal or photodynamic therapy. Al-though stent placement is generally a simple, safe andeffective method, there are sometimes complications,increasing the morbidity and mortality rate. Bypassoperative procedures have now been abandoned as afirst choice. The stomach instead of the colon must beused for a bypass operation when it is needed. Chemo-therapy, despite the toxicity, and intraluminal radiation(brachytherapy) have a well-defined role. It is inoperable when firstmanifested in more than 50% of cases.
