Hello and thanks for your post,

I am sorry to hear about your situation. 

Immunotherapy uses are immune system to fight cancer. It works by helping the immune system to recognise and attack cancer cells.

From what I have read there does not seem to be enough information from clinical trials that have looked at the safety aspects of using immunotherapy with patients and autoimmune diseases. This may be the reason that your doctor is reluctant to consider immunotherapies. There are NICE (National Institute for health and Care Excellence) guidelines that doctors follow which may exclude patients with autoimmune conditions.

If you have a rheumatologist who is monitoring your psoriatic arthritis you could also ask their opinion.

You may find that other patients post with their experiences or you could always post  on a different thread where you may get more responses. Everyone's situation is slightly different though and it is difficult to compare one persons situation with another.

You could also consider getting a second opinion from another oncologist but you may have to pay for it. We have information on getting a second opinion here

I am sorry not to be able to help more but you are more then welcome to ring and discuss any of this with one of the helpline nurses. Our number is Freephone 0808 800 4040.

All the Best,

Catherine
