Neuro endocrine cancer

Hi all, has anyone on here got experience of neuro endocrine cancer. I had a tumour in my bowel which was removed in 2020. Eight months remission after Cisplatin and etoposide. Recurrence so 35 cycles of Folfiri which has now stopped working. Can anyone suggest a good neuroendocrine oncologist for a 2nd opinion,mine is a bit negative not to mention slow to respond to anything.
