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

thank you ....you are correct ....he had the radiation 30 treatments on Head neck for original diagnoses ....then when it spread to the thoracic lymph nodes he had another 30 rounds of radiation and then he started Avelumab ....immune therapy ....and his tumor was 12.7 cm ...now is 5.4 after the completion of radiation and 8 rounds of Avelumab....so we are hoping

I have recently visited a specialist in MCC who told me that immunotherapy along with radiation was the most effective therapy .
I encourage you to ask your oncologist about it.

Thank you so much for responding. I also had esophageal cancer three years ago and it was caught early. Then two years ago I had prostrate cancer surgery.
Some how this Merkel has me much more concerned. So thanks again for sharing with me.

My husband was diagnosed with stage 3B merkel cell on his nose .....they removed it in July 2021 with complications due to heart issues landing him on Life support ...but after 1 month in the hospital he was doing well. He then had 30 lymph nodes on Right side of his neck removed.... 1 showing merkel cell as well.
followed by 30 rounds of radiation .....then in Sept 2023 the seen on CT scan showed an enlarged lymph node in thoracic region (Left / centre towards back of Stomach) encasing the descending Aorta.....they watched that too long ....it went from 2.4 cm to 12.7 cm in 5 months ...had a biopsy that confirmed Pathological Merkel Cell ....which again was 30 rounds of radiation ....followed by at present ....Avelumab ....Immune therapy ....4 months following completion of radiation with 3 months of Avelumab the tumor has shrunk to 5.4 cm ...but now that the merkel cell has spread to a distant location ...I believe it is now Stage 4 ...and I am really worried...since Merkel cell is aggressive.....my sister in law is stage 4 Melanoma and My brother in law is stage 3 lung cancer ....all siblings ..to my husband who also survived prostate cancer 12 yrs ago ....sorry for the rambling and so much to take in .

I was diagnosed with MCC 2+ years ago in my R forearm. Tumor removed, all was good. Petscan was clear. January of this year BANG ! TUMOR via lymphnodes R Axillary. 36 rounds of radiation, again all was right with testing. No signs of the cancer. 2 weeks ago MMCC has advanced to my pancreas and some weird lymphnodes in the core of my body that they say can't be checked as they can't get to them via needle biopsy. My tumor DNA bloodwork has gone crazy high.
Has anyone ever been treated with Keytruda and how did it effect you. I start treatments on Monday, every 3 weeks. A bit nervous but hopeful. Would love to here any other experiences with this treatment. Best wishes for all.

Hello @penlandr1,

I see that you are interested to hear from others who have been treated with Keytruda. In a post above, @lenny48ca, mentions Keytruda. Here is a link to his post on May 20, discussing this: https://connect.mayoclinic.org/comment/1071523/.

Feel free to read his post and then ask him questions about his treatment.

You said that you were going to start Keytruda on Monday for three weeks. Will you be having the treatments every day?

I am a caretaker for my partner that has been diagnosed with MCC last month. Currently working on a treatment plan that should start in 2 weeks. She had basal and squamous in situ numerous times in the last 10 years. Never any skin issues that were deemed MCC in pathology. Suddenly had a golf ball size lump in axillary left lymph node. Biopsy revealed MCC. PET showed metastatic to left humerus bone only. Stage 4 diagnosis, and seems that the universal treatment for this is immunotherapy...not sure yet what medication will be recommended. Leaning toward Keytruda (pembrolizumab)....or Bavencio (avelumab). Has anyone taken these meds that would share their experience?
