I want to get another opinion on my melanoma. Seeing as how I got cheated badly when I did this before, I think I need some advice before I proceed to send the slides to another lab. I’ve seen others on this board mention Dr. Mihm.
Can anyone help me?November 5, 2012 at 10:48 pm #57405Catherine PooleKeymaster
Do you just want another opinion on your pathology? Then by all means go to http://www.drmihm.comand you can have your slides sent for his evaluation. If you want a complete exam etc, that would be different. Where do you live? I can suggest some places for you.November 5, 2012 at 10:51 pm #57406 Is this on your melanoma from 2011? Not another new one, right?November 5, 2012 at 10:52 pm #57407 Can always send to Dr Mihm for another opinion: Contact them first before sending your slides, though, I think there is a form to also fill out with demographics, billing info, etc…

I live in Mississippi. I sent Dr. Mihm an email via his website. Nobody has replied just yet. I don’t want a physical exam or anything like that. A re-evaluation of my slides with an opinion (ie, prognosis) is what I’m looking for.
Thanks to both of you for the help.November 6, 2012 at 2:32 pm #57409
You might have better luck and a quicker response by sending an email directly to this person:

Thanks for the tip. I wonder if Dr. Mihm’s report would reveal the actual percentage of regression my melanoma had.November 6, 2012 at 3:51 pm #57412
I don’t know if he states % or not, but I know he addresses it. This is my exact report from Mihm from July:
A: Malignant melanoma, superficial spreading type, invasive to level II and a measured thickness of 0.3 mm. Close to lateral margin.
A: This lesion, in my opinion is definitely a malignant melanoma. It is microinvasive and it is in radial growth phase. I find no mitoses, no evidence of true ulceration or regression. I consider the lesion to be a pT1a. I would suggest a re-excision with 1.0 cm. margin. Thank you for the opportunity to review this interesting case and please accept my warm personal regards.November 6, 2012 at 4:46 pm #57413
Sounds good to me. I think if he wrote that much for yours, he would definitely have something to say about the severe regression that mine unfortunately toted.November 7, 2012 at 3:34 am #57414Lisa PParticipant What exactly is regression?November 7, 2012 at 10:20 am #57415 Regression: An attribute that may be either absent or present in the radial growth phase (which is adjacent to the vertical growth phase). Regression is evidence of destruction (probably by immune factors) of some of the melanoma cells in the radial growth phase. Immunologically mediated regression of this sort is a weakly negative factor.November 7, 2012 at 3:31 pm #57416Lisa P wrote:
What exactly is regression?
It’s something you don’t want to see in the same sentence with “prominent” or “extensive” on a pathology report. Up until about ten years ago, extensive regression was thought to be a very ominous sign that indicates a lesion with greater potential for metastasis.
For some reason, the issue is ignored by a lot of people who should be interested. It wasn’t even taken into consideration when the 2009 staging criteria were being decided. No one really even agrees on how to measure it. I do know of one respectable study on the matter that has taken place in the last couple of years, but it only included lesions with a vertical growth phase. The conclusion was that lymphovascular invasion was more prevalent in lesions showing “complete regression” of the radial growth phase.
Some melanomas are completely erased by regression. Those are nearly guaranteed to metastasize.November 7, 2012 at 5:43 pm #57417Lisa PParticipant
Thanks for the info. So, am I correct in assuming that regression can result in the visible melanoma/pigmentation disappearing from sight, but heading downward (vertically)?November 7, 2012 at 6:11 pm #57418
This is the best study on regression I’ve seen. Alas, as I mentioned earlier, only vertical growth phase lesions are included.
” In complete regression melanoma cells are absent in the overlying epidermis; whereas in partial regression they are present in the epidermis.9 RGP regression is common, particularly in thin lesions. The incidence of regression in melanomas of all thicknesses has been estimated at about 10–35%, and as up to 58% in melanomas with thicknesses of <0.75 mm.3,18"
“RGP regression has been shown to be associated with an adverse clinical outcome, both in lesions without and with an adjacent VGP.9 The presence of complete regression in the RGP of lesions with VGP was associated with poorer survival in a prognostic model published by Clark et al.4 The extent of regression in thin melanomas also has been associated with poorer prognosis.”
