Melanoma: What are your tips about immunotherapy (Keytruda)?

Posted by williamfh @williamfh, Dec 29, 2024

It started a year ago, nodular melanoma on my right arm. Had incision to remove. Stated they got it all. Checked two lymph nodes. One negative, 1 small traces of cancer cells. A year later, two pumps come up very near the same spot. Its cancer again. Doctor wants to try Keytruda, Neoadjuvant immunotherapy. Starting the drug before the tumor is taken out. I'm concerned the tumor will grow in 6 weeks and may spread while getting treatment, which could make things worse. She states I'm a good candidate because of my positive TPS 6-10% and my TMB 52.6. After reading up on this drug I'm very nervous about the side effects, many that are permanent and non reversible. Latest stage diagnose is melanoma stage 3C because it recurred. I'm kinda at a loss with direction to go. Any experience using this drug out there?

Just had the 2nd tumor taken out on my arm. After a pet scan nothing showed up in my body, other than a small, small spot on my arm again, but so small they couldn’t feel it or couldn’t pick it up on the ultra sound… so nothing happened at that spot. Will be doing a biopsy on the tumor to see if the immunal therapy is working.

@williamfh, have you had the biopsy? Any update? How are you doing?

I was diagnosed with melanoma had the middle lobe of my right lung removed. The oncologist is going to start me on immunotherapy keytruda. Everyone asks three weeks does anyone have any experience with this drug. And how do you cope with all of this

To Charlene 9. I have been on Keytruda for kidney cancer for a year now with 5 more infusions to go for a total of 18. For me the only side effect up until now has been severe skin rash. The malignant tumor has reduced in size slightly and cancer has not spread.

Thanks I will. I'm going in every 6 weeks with 400 MG

PS Best of luck with your surgery! I've read there are excellent results with this type of approach. Be sure to keep us posted.

I go for my 5th infusion of 200 mg tomorrow, another 3 weeks after that then I graduate to 6 weeks 400 mg.

The way I see thus metastatic melanoma and can explain it is it’s as if Freddie Krueger is lurking around in my body. I won this first installment but he might be hiding somewhere stirring up some trouble where he remains undetected and I’ve got to keep my defenses up, ready to pounce in case he strikes again - or hopefully prevent him from getting strong or courageous enough to strike again!

Oh Wow!!! YEA! I just had my second one yesterday and am scheduled for resection to take out the tumor March 4th. So they are saying immunotherapy for 2 years? And you have only had 3 so far? Are yours 3 weeks apart at 200mg or 6 weeks apart at 400mg? Seems if it had a full resolution after the scan you would just finish out the year? What's the reasoning?

REPLY

Amazingly, thanks for asking. After 3 infusions I had a follow up CT that incredibly revealed full resolution of my 11 mm metastatic lung nodule! I still have to continue with immunotherapy for up to 2 years but obviously this is so encouraging.

Welcome @williamfh to the club no one wants to be in, however, I have to say I find the support to be tremendous and much needed. Hope we can provide the same to you, although it helps to keep in mind of course every case is individual and what works for some - or how some react - may not be the same for everyone.

As a retired medical professional myself, I also did quite a bit of online research. One thing I learned is advances in melanoma are taking place so rapidly that treatments and prognoses we find by google searches may be outdated. It helps to always check for more recent data and/or for participating in sessions offered by reliable organizations. For example, I've participated in zoom sessions conducted by the Melanoma Research Alliance and will be attending one at a nearby university in a few weeks. This is due to my own diagnosis of Stage 4 metastatic melanoma nearly 5 years status post WLE of a 1A amelatonic skin lesion. I am due for my third Keytruda infusion next week; to date, I've experienced no untoward side effects despite being informed and reading of several potential ones online prior to treatment. The infusion staff has been very reassuring about the low incidence they've observed with this form of immunotherapy.

I'm also a candidate for possible surgical removal of my identified lung nodule once I undergo a CT scan later this month. The rationale for this is based on a SWOG study my oncologist referenced and I found more readilyy explained in an NIH document Immunotherapy before Surgery Appears Effective for Some with Melanoma.

I hope these references provide you with some additional resources.

How are your infusions going? Have you noticed any change in your prognosis?
