Merkel Cell Carcinoma: I'd like to hear from others

I'm finding it hard to find more current information about merkel cell carcinoma. It's traveling from my forearm and up into the lymphatic system under my right arm.

Hello @hunter59 and welcome to Mayo Connect. I appreciate you sharing your journey with Merkel Cell carcinoma. It sounds like your treatment was quite effective and that your medical team was able to assist with the side effects. You mentioned that the Keytruda affected your thyroid. Has the thyroid problem been treated with medication?

How are you feeling now?

I was diagnosed with stage 4 Merkel cell carcinoma in Jan 2022 when I developed a lump in my neck. Biopsy confirmed the type of cancer and further test indicated it spread to my liver as well. I started immunotherapy in March on Keytruda and have been getting this every three weeks since. The liver is clear today and the lump in my neck has reduced in size to where it cannot be felt but scans still show it is present. We have no idea where this cancer started never noticed anything on the skin. I previously had esophageal cancer and had my esophagus removed and stomach pull up along with chemo and radiation. That was seven years ago and there has been no recurrence. The Keytruda affected my thyroid but it is now under control and I have had no other side affects. So the plan is to continue on the Keytruda as long as I continue to tolerate it. Keep positive thoughts as treatment options are always improving outcomes as research continues.

Hi - sorry to hear that. I, too am Stage 3 Merkle cell carcinoma, diagnosed in April.

I am 57 year old woman - survived breast cancer in 2015. I am otherwise healthy and very active. I wasn't sick one day with the chemo I received. This immunotherapy has made me very sick. I started a two drug (IPI & Nevo) regimen immediately after diagnosis. I didn't get sick until after the third treatment, pancreatitis and colitis. This forced me to stop the cancer treatment until the steroids (really high dose prednisone could get it under control)
After more than 3 months, I finally received another immunotherapy treatment since my pancreas numbers were close enough to normal. Yikes, right back to pancreatitis. Back on prednisone 🙁

This is my first post as well.

Hi. I’m a 72 year old male. I was diagnosed with Merkel cell on my right forearm 11 years ago. It just appeared as a bump under my skin. Luckily I already had a dermatologist appointment scheduled a week later. The biopsy revealed Merkel. Even more rare at that time, there was no specific treatment. I had a PET scan that showed a few affected lymph nodes under my arm. We did surgery almost immediately, followed by 30 radiation treatments. Other than some fluid buildup under my arm I had no other complications. The incision on my arm took almost a year to heal because of the radiation treatment I get scans every 3 months due to this and another cancer. No signs of any reoccurrence. I wish everyone diagnosed, the same good outcome I had. And RIP JB 🏝️

I just found this group and read the comments. Because this is such a rare cancer, I thought I'd add my story for what it's worth. I've just had my latest check-up two years out from finding out I had Merkel Cell - a little purple spot on my forehead that my dermatologist did not at first think anything of. I have been going in two or three times a year for dermatologist sessions for about ten years as I've had several instances of melanoma, squamous and basal cell carcinomas - probably from years of sailing. I didn't like the purple bump on my forehead and asked him to remove it more out of vanity than concern, but he was happy to send it in for a biopsy and found out it was serious. He told me he hadn't seen one in twenty years of practice and he sent me immediately to MD Anderson for treatment. Everyone here has experienced or knows about what's next with Merkel Cell - lots of doctors and excision surgery followed by decisions about follow-on therapies. I was terrified after I read up on what Merkel Cell was all about. The MD Anderson folks were really great about calming me down and dealing with what I needed. I was VERY lucky as the excision surgery and sentinel lymph node removal showed that I had gotten treatment early enough to be "stage 0" (in situ) and the very large incision site healed very well and ended up looking like an extra frown line on my face. Even with that, I am still going back to MD Anderson regularly for a CT scan and a chest x-ray and blood work to monitor things. This will continue this for three more years minimum they say. My dermatologist still talks about my case with me when I go back for my regular 4 month check up because it is so rare. Bottom line, I think, is to get regular exams but also be your own advocate. If you see something on your skin that you are worried about, get it removed and get a biopsy. There are worse things than finding out it's nothing after the lab takes a look. I also have become really really vigilant about limiting outdoor exposure (no more sailing) sun screen, sun glasses (it can appear in eyes too), hats and fishing shirts with long sleeves when I go outdoors. I look like a dork in the pool when I'm with my grandkids (and even then I sit under an umbrella mostly), but I'm alive and that's a fair trade in my book. I have real empathy for people going through this and appreciate finding this group. I wish everyone the best.
