PET or MRI scans necessary?

      Hello everyone, 

       

      I'm back with what is probably only the beginning of the newbie questions.

      The basics: fiancé diagnosed with melanoma last week. Breslow thickness 1.15 mm, Clark level 3/4, mitotic rate 1, no ulceration, melanoma excised with clear (but very narrow) margins, abdominal ultrasound, chest x-ray and bloodwork all clear. First appointment with melanoma specialist the week after next. 

      We anticipate that the next step is the wide local excision and the sentinel lymph node biopsy. We are really hoping that the SNB comes back negative.  If it doesn't, I guess we start looking at treatment options.

      If it is negative, however, are there other scans or imaging technologies we should be pushing for to ensure that there really is no melanoma elsewhere in the body? I've read about PET and MRI scans being used in more advanced cases, but it sounds like for stage 1 melanomas, if the SNB is negative, doctors usually say "congratulations" and send you home. However, fiancé is concerned that the SNB might miss some signs of spread. Would it be worthwhile to push for further scanning (in addition to the already-completed chest x-Ray and ultrasound), or would that be excessive? (I should add that we're in Canada so insurance coverage or costs are not an issue).

      Thanks  in advance for any ideas you might have.

          Hi Ocelot,

          I too am a patient from Canada (please see my profile for details) May I ask where you guys are located? I am in Ontario and even with Stage III patients like myself that are NED they do not perform scanning (PET,CT or MRI) unless there is convincing evidence of probable disease. I think the best thing to do right now is to go through with the SLNB and hopefully all is all clear. Once you have the results of that then you and your medical team can decide what to do next.

          Best of luck to your fiancée

                Sorry you have to deal with this.

                I know  how scary this whole melanoma thing is, been there done that.  For your fiance's stage, unless upstaged by the SNB, he would not need any further scans ex. PET / CT.  Both expose you to high doses of radiation and due to thier extreme sensitivity, result in MANY false positives.  Then you have more surgery to deal with that etc.

                In all probability melanoma usually comes back to the nodal basin.  That being the case, there is argument for following up with ultrasound of the basin to catch anything earlier.  The chest x-ray and bloodwork are controversial as they have a very low yeild on catching any advancement.  Chest x-rays once or twice a year are far more benign than CT so would be a happy compromise as far as scanning.  Bloodwork won't become abnormal until there is enogh disease to cause abnormalities at which point most people have symptoms that would warrant a follow up check anyway.

                A good PE and skin check is the best follow up for his stage at this time.  Hopefully the SNB is clear.

                I do realize that skip metastasis and blood stream spread occur with mel but at a much lower rate.  Unfortunately I was one of those.  Now stage IV but NED for almost 5 years after HD IL-2 and lung surgery.  I am currently pushing to drop the PET/CT all together since I have had no less than 6.  Radiation exposure never goes away and is cumulative.  I am only 46 and don't want to initiate another cancer.  Thats just me though :).
