  • Would very much welcome any shared experiences/ advice as support from my hospital for longer term side effects is virtually non existent. Also, GPs and A&Es have limited understanding of immunotherapy and related toxicities.

After stage 3B groin dissection I had 6 out of 8 scheduled Pembros but in Jan ‘23 had a PNEUMONITIS side effect. Steroids ( Prednisolone) alongside Lansoprazole antacid. During 2023 my steroid/ antacid intake was very- in fact too high as due to lack of support I was self diagnosing recurrences/ self prescribing steroids. Later, on advice of a different hospital I avoided the steroids ( as from September ‘23) but from the same advice continued the Lansoprazole. I only stopped Lansoprazole a month ago via my own research and decision and began taking low dosage B12 and magnesium supplements.

     I had several reinfections ( chest) in 2023 and in December a bad one eventually diagnosed as haemophilus influenzae. In terms of the cough/ mucus symptoms I recovered by end of January. However, I have never- if this makes sense- felt 100% ok since my pneumonitis side effect. Well, in truth since I started Pembro ( I initially had vitiligo followed by intense itching). I now have increasing periods of my body feeling very cold especially after eating. Also intermittent and uncontrollable outbursts of sadness/ tears and mild tremors in my hands/ head. In between times I can have a period of feeling pretty ok and my wife and I might attend a gig/ theatre etc but I then regress again. A rollercoaster.

     I have asked my cancer specialist nurse and my plastic surgeon for immunology and/ or endocrinology checks but they won’t refer me within my cancer hospital. I have only this week had blood tests at another hospital but such have been the huge impacts on our lives for over a year by now. We cancel over half of our bookings, can’t commit to travel/ holidays, miss seeing our grandchildren , etc as I cannot predict from one week to the next how I will be. I am now having to seriously consider private medicine for immunology/ endocrinology checks- much against my moral compass. But I’m desperate.

Any shared experiences of what my ongoing side effect symptoms might be would be immensely useful . Thanks !

  • I have now had 9 Pembro and recognise your difficulties.  If you have not discovered it yet, I recommend without reservation the FB page Melanomamates.  All are unfailingly polite and helpful fellow melanoma patients, many with real-life experience of Pembro and it's actual side effects, also of other Hospital Trusts. The page also has an excellent search function for past posts similar to your issues.  I have no personal direct answers for you but recognise the feeling cold and the tremors (I often sit with a hot water bottle on my abdomen, regardless of room temperature).  Guys Hospital has an excellent dermatology wing fortunately for me but even so I find fellow patients often much better informed about actual real life problems. Wishing you well.
