Are there any other lymph nodes involved ? Has the patient been fully staged with PET and also laparoscopy ?
Of course this would have been M1a on TNM 6 but this is no longer the categorisation. However this patient must have a very high risk of occult micrometatstatic disease given the distribution of the cancer
PET is quite important you would think as somewhere between 10-30 % of these patients may have additional updtaging after PET in this scenario.
For upper SCC we normally treat with definitive CRT if local disease. Were you considering surgery as part of the treatment depending on the coeliac node staging ?
