Treatments Beyond Localized Skin Surgery for BCC, SCC, and Localized Melanoma
Intralesional MTX
A 38-case retrospective study and literature review concluded that intralesional MTX is a beneficial nonsurgical treatment option for keratoacanthoma. Resolution occurred in 92% of cases, after a mean of 2.1 injections at a mean of 18 days apart. There were 2 reports of pancytopenia in patients with chronic renal failure.15
Cemiplimab
Cemiplimab is a programmed death receptor-1 blocking antibody that is FDA-approved for the treatment of patients with metastatic cSCC or locally advanced cSCC who are not candidates for curative surgery or curative radiation.16 Results of phase 1 and phase 2 studies (NCT02383212 and NCT02760498) demonstrated response to cemiplimab in about half the patients with advanced cSCC. AEs associated with the study drug occurred in about 15% of the patients in the metastatic-disease cohort of the phase 2 study. These AEs included diarrhea, fatigue, nausea, constipation, and rash; 7% of the patients discontinued treatment because of an AE.17
Melanoma
Lentigo maligna is a melanoma subtype with a good prognosis. However, it also has the highest rate of recurrence of all the subtypes when treated by surgical excision alone. Neoadjuvant imiquimod has been used off-label to reduce surgical margins in lentigo maligna.18,19
Summary
Although the treatment of BCC, SCC, and localized melanoma traditionally involves skin surgery, several novel alternative treatments are available for BCC, SCC, and localized melanoma.

Nurses
Joint Provider Accreditation Statement
In support of improving patient care, this activity has been planned and implemented by Postgraduate Institute for Medicine and Global Academy for Medical Education, LLC. Postgraduate Institute for Medicine is jointly accredited by the Accreditation Council for Continuing Medical Education (ACCME), the Accreditation Council for Pharmacy Education (ACPE), and the American Nurses Credentialing Center (ANCC) to provide continuing education for the health care team.
Continuing Nursing Education
The maximum number of hours awarded for this Continuing Nursing Education activity is 2.5 contact hours. Designated for 2.4 hours of pharmacotherapy credit for advanced practice nurses.
Educational Needs
Dermatologists can benefit from education on recent developments in many areas of clinical practice. In psoriasis treatment, nearly all patients are prescribed topical therapies. New medications using improved vehicles and fixed-dose combinations have become available, and more are in development. New research linking psoriasis and risk of cardiovascular disease has provided a better understanding of the underlying pathological mechanism and the potential benefit of anti-inflammatory treatment. Recent epidemiologic data on atopic dermatitis in adults have important implications for diagnosis and treatment. In acne treatment, several efficacious systemic treatments are underutilized, and education on their risks and benefits may improve clinical practice. In the treatment of skin cancer, dermatologists should consider several systemic treatments in addition to surgery. Finally, a new botulinum toxin became available recently, and others are in development.
Learning Objectives
At the conclusion of this activity, participants should be better able to:
- Describe recent data on psoriasis treatment, including new vehicles for topical treatments, fixed-dose combination therapies, and investigational topical medications
- Review the relationship between psoriasis and cardiovascular disease (CVD) and the potential effects of psoriasis treatment on CVD risk
- Describe current research on the temporal patterns of atopic dermatitis onset and resolution and the differences in diagnosis and treatment approach for adult and pediatric patients
- Analyze the efficacy and safety of systemic therapies for acne
- Assess the current nonsurgical treatments for basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and localized melanoma
- Review the options for confirming the diagnosis and data on the use of topical and systemic treatments in the management of onychomycosis
- Assess the advantages and disadvantages of available botulinum toxins used to address patient concerns about facial aging
