Distribution of lymph node metastases on FDG PET/CT in inoperable or unresectable oesophageal cancer patients and the impact on target volume definition in radiation therapy
Definitive chemoradiotherapy (dCRT) is standard care for localised inoperable/unresectable oesophageal tumours. Many surgical series have reported on distribution of lymph node metastases (LNM) in resected patients. However, no data is available on the distribution of at risk LN regions in this more unfavourable patient group. This study aimed to determine the spread of LNM using FDG PET/CT, to compare it with the distribution in surgical series and to define its impact on the definition of elective LN irradiation (ENI)
