Hello

My brother has just turned 60 and has been  diagnosed with oesophageal cancer and the  hospital has said that they will treat  the oesophageal cancer with view to operation but they suspect that he has a small area in the liver that could be cancer.
Basically they are saying that he will receive chemotherapy treatment with view to operate the oesophagus

but because they have not done a biopsy to confirm the  liver cancer they  told us that if after the first 4 treatments if the spot  in the liver shows to have become smaller they  will not continue with chemotherapy to operate the oesophageal cancer but then only proceed with palliative treatment instead as we have been told that  is not their practice.at that hospital ? Or perhaps the trust ? 
I was wondering if this is  a wide practice in all other NHS Trusts or is this an approach to this specific hospital ? Or NHS Trust for this specific area ? 
please can someone tell me if  anyone is familiar with this practice? I would like to hear if liver cancer has been addressed and treated if another cancer is  present in another part of the body ?
i am wondering if is it unique to this specific hospital? Or Trust ?
we are all aware that it is not curable but to give up treatment and go into palliative care and not operate the oesophageal cancer but to just leave and provide just palliative care leaving a 60 years  old  with only a few months? 
thanks
