Katherine:

What approaches are currently available to treat these more common forms of advanced non-melanoma skin cancer? 

Dr. Davar:

Right now, the most common mode of treatment is typically treating cancer that is localized.  

Again, even with the extremely increasing incidence of these cancers, the vast majority of cancers that we detect are still localized and are amenable to easy surgical eradication by a trained dermatologist or a trained mole surgeon. A trained dermatologist, a trained mole surgeon, a plastic surgeon, these are commonly the physicians that encounter these patients. Surgical removal is still the primary mode of eradications of these lesions. However, increasingly, there is a role for early systemic therapy and local regional therapy to improve patient outcomes for reasons that we can talk about. Still, the vast majority of patients are still treated surgically and then increasingly, there is the role for referral to medical oncologists and radiation oncologists to talk about alternative forms of treatment that may be needed after that. 

Katherine:

What sort of alternative therapies? Are you looking at targeted therapies? Immunotherapies? 

Dr. Davar:

The primary reason for which advances have happened in this disease is really the advent of effective systemic immunotherapy and the spillover of immunotherapy into the patient landscape in these diseases. The reason for that is as follows. Immunotherapy essentially is most effective in tumors that carry a high tumor mutation burden. For example, melanoma has a tumor mutation burden on average of about 15, and the tumor mutation burden in melanoma is driven by the fact that melanoma, cutaneous melanoma is an ultraviolet light-driven skin cancer.  

However, non-melanoma skin cancers have tumor mutation burdens that are many, many magnitudes higher than that of melanoma. For example, the median tumor mutation burden in cutaneous squamous cell carcinoma is 50. Melanoma is 15. The median tumor mutation burden in cutaneous squamous cell carcinoma is three times that of melanoma. Similarly, for Merkel cell carcinoma. A large majority of Merkel cell carcinoma is caused by an unusual virus known as a Merkel cell polyomavirus. Both the viral driven tumors and the non-viral driven tumors have high tumor mutation burdens, and the same is true of basal cell carcinoma because of ultraviolet light exposure.  

The primary reason why immunotherapy has gotten a foothold in these diseases is because the underlying etiologic agent that drives carcinogenesis, ultraviolet light for the majority of these, and the Merkel cell polyomavirus for the subcategory of non-melanoma skin cancer that is Merkel are both associated with a response to immunotherapy.   

As a result of that, immunotherapy, anti-PD-1 immunotherapy is now standard of care for patients with tumors that are either locally advanced undissectible or locally advanced and/or metastatic, that is, that they have spread. They are now available for use and FDA-approved for this indication in both Merkel, basal, as well as non-melanoma cutaneous squamous cell carcinoma. 

Advanced Non-Melanoma Skin Cancer: Who Is on Your Healthcare Team?

What experts make up an advanced non-melanoma skin cancer care team? Dr. Sunandana Chandra shares an overview of typical team members who work together for optimal patient care.

Dr. Sunandana Chandra is a medical oncologist and Associate Professor of Medicine at Robert H. Lurie Comprehensive Cancer Center of Northwestern University. Learn more about Dr. Chandra.

Katherine:

People with advanced non-melanoma skin cancer typically need a multidisciplinary team. Who all is on that team? 

Dr. Chandra:

So, typically the members of a multidisciplinary team include a dermatologist, including potentially a Mohs surgeon if one is available, a surgeon or a surgical oncologist, a pathologist, specifically, a dermatopathologist, if they’re available, because they really focus on scan pathology.  

A medical oncologist, a radiologist who could help us read the imaging, and a radiation oncologist who can actually use radiation to treat certain spots. Now, in addition, we can often also include our palliative and supportive oncology colleagues, especially in the settings where people may have some difficult-to-treat symptoms. They may have enough of an advanced disease where we need to start kind of talking about a person’s goals of care and what their own wishes are for their cancer management and for their life. So, these palliative and supportive oncology colleagues are very, very helpful in those situations. 

Katherine:

Are there also people like social workers, nutritionists? 

Dr. Chandra:

Absolutely. Absolutely.  

So, you know, our social workers, our nurse navigators, our nutritionist and dietitian colleagues, our nurses, our nurse practitioners, I mean, our pharmacists, it takes such a village to help take care of our patients. And I hope a patient or a person realizes that having this village at their fingertips and at our disposal only enhances their care. It’s not meant to complicate their care. It’s not meant to add unnecessary appointments. It’s just to really deliver expert care by each of these individuals who really have a focus on a particular aspect of the delivery of care.
