Hi Pam, I don’t know if I have P53 gene deletion but despite having both velcade and lenalidomide, since September 2015, my light chains and paraproteins are stubbornly high (1000 & 38) . My consultant never mentioned fish, cytogenics or deletions. I asked him about it but he said he didn’t think it was necessarily important!? His response now is to apply to the cancer fund in Northern Ireland for pomalidamide. Has VTD pace worked for you and what has it brought it down to?
