Momentous Melanoma Marker Modality?
Clarke et al published a study online on March 2 in the Journal of Cutaneous Pathology regarding a novel diagnostic test for melanoma....
What does your patient need to know at the first visit?
Melanoma patient visits and communications are complicated. When possible, you can preview the surgical and prognostic expectations with the patient when you see the lesion clinically for the first time, especially for a lesion that you’re sure is melanoma before it even hits the specimen cup. Sometimes you have to convey important biopsy and treatment information over the telephone, or sometimes you have the luxury of an extra clinic visit to discuss it with the patient and perhaps a family member in person.
During the first set of conversations, I explain the things that are tangible: the depth of the lesion, the relationship it has to prognosis, surgical options based on staging, further testing/referrals, and known risk factors. Then I wait. The digestion phase is critical before you hang up and schedule a surgery.
Probably the most important thing I tell patients is that melanoma is unpredictable. Not everyone has the same kind of “surgery,” we don’t say “remission,” we don’t have a certain “chemo” that we know will be best, and not everyone will need “CAT scans.” I tell patients that they’re stuck with me. Skin examinations, talk of sun protection, photography of nevi, upkeep of health maintenance visits with other specialists (eg, primary care physician, optometry/ophthalmology, gynecology, dentistry), and education of family members on melanoma risk factors will be the norm.
What are your go-to treatments?
In the past, surgical management was perhaps streamlined, but as we learn more about melanoma tumor biology, the less we can form generalizable guidelines for surgery, margin control, and lymph node perusal. Wide local excision is paramount, but the evidence that guidelines for 0.5-cm, 1-cm, and 2-cm margins or greater fit for all types of tumors is lacking, and many have challenged the recommended margins, particularly for lentigo maligna subtypes (Kunishige et al).
The 0.75-mm Breslow depth threshold guides my sentinel lymph node (SLN) discussion, with upstaging based on primary tumor mitotic index and/or ulceration. But SLN biopsy is always still a discussion and not a foregone conclusion because the risk-benefit ratio and prognostic/survival data are very difficult to dissect for some cases. Certainly, mention of SLN biopsy morbidity, including lymphedema, is warranted before the patient consents. Then there is further explanation that more invasive lymphadenectomy could occur based on SLN findings. If applicable in advanced cases, options for imaging and adjuvant therapy are introduced by us but then primarily led by oncologists.
Patients are generally pleased that the approach to melanoma surgery, reconstruction, SLN biopsy, and oncologic care is increasingly becoming (almost) harmoniously multidisciplinary. Larger institutions have streamlined their melanoma providers into shared clinics or at least regional networks—dermatologists, plastic/otolaryngology/oncologic surgeons, oncologists, and radiation oncologists, for instance—and simplified patient access based on individual tumor treatment plans. Dr. Christopher J. Miller at Penn Medicine (Philadelphia, Pennsylvania) is excelling at a collaborative surgical approach for melanoma between dermatologic surgery and specialties such as otolaryngology and also spearheading the Mohs micrographic surgery approach for primary melanoma as possible standard of care for some cases (Etzkorn et al).
Also evolving is the access to clinical trials and care coordination regarding the most novel metastatic melanoma therapies, which can now be a short drive away for most patients as the National Cancer Institute broadens its clinical trial reach.
After the diagnosis of melanoma is made, care is becoming much more individualized for surgery and beyond, but true morbidity and mortality benefit for the more complicated regimens has become anybody’s guess as this research field grossly and rapidly swells. Then these discussions with the patient become longer and more open-ended.
How do you keep patients compliant with treatment?
Initial surgery and multidisciplinary management requires meticulous communication between providers to ensure that pathology reports, surgical findings, imaging, wound care, and follow-up are transparent. The easier it is for patients to navigate the medical system(s), the more likely they are to comply. Voicemail, e-mails, text messages, and/or mailings are standard for different offices for reminders, but an old-fashioned telephone call goes a long way for a patient who has melanoma on his/her mind. Adherence to sun protection, health maintenance, and skin examination appointments is then the challenge.
Sun protection strategies were well-represented in the Cutis July issue’s Practical Pearls featuring Dr. Vincent A. DeLeo. My script for sunscreen-averse patients as I leave the room is “Take a mosey through the sunscreen aisle. You may be surprised at what you find.” And sporting goods stores are chock full of UPF (UV protection factor) clothing options. I’m not a scolder, but I do utilize the power of repetition/the squeaky wheel.
