Recurrent Liver Cancer After Liver Transplant

I was wondering if anyone has gotten liver cancer HCC back after transplant and what treatments they received .My husband has recurrence 6 months after transplant hcc in only 1 lymph node in the gastro hepatic ligament .Weve read the only true cure is resection and removal of all those nodes .We are scheduled for surgery soon. Can anyone tell me what treatments they received due to already being on immunosuppressive Thank you
