TVEC with mucosal melanoma of the mouth

I started TVEC injections in my mouth in November 2019. This is the first time my oncologist at the James has tried this procedure in the mouth. I have not found anything anywhere that can give me any information about anyone out there that has had this treatment done in their mouth and the outcome. I have positive changes occuring, but they could not do a sentinel node biopsy due to the location, and the PET scan is not that reliable for detecting lymph nodes in that area. I did not have metastasis to any organs or brain at the time of the PET scan at the end of October.

History: I went to my dentist after my mastectomy with a sore in my mouth in June 2019. She gave me medication for infection. Went back 3 weeks later and it was worse. She sent me to the periodontist, and a few weeks later he said he didn’t know what it was and was going to do a biopsy. My rheumatologist instead wanted it performed by a dermatologist. A few weeks later I went to my regular dermatologist who said that the area was too vascular and wanted a surgeon in their office to do it. A few days later I went in and he said the lesion looked vascular and no worries. Did the biopsy. He called me a week later and apologized because he said he only has seen two of these in his entire career, and mine was the second. It was a blow, because I knew how serious and aggressive this cancer is. It had grown significantly between June and October, when I was finally diagnosed.

I am telling this story to help others who may not take a sore in their mouth seriously. I thought I had an infection, as well. Has anybody on this forum had mucosal melanoma and TVEC injections? Thank you!
