In medical practice, physicians are sometimes faced with patients who reject the gold-standard treatment for a condition. In this hypothetical clinical scenario, we present the case of a patient who refuses Mohs micrographic surgery for management of infiltrative basal cell carcinoma and instead requests off-label therapy with imiquimod. We discuss the treating dermatologist's options in response to this patient's request and the ethical considerations surrounding the case. We conclude that the physician has the right to refuse to provide treatment that deviates from standard clinical practice but that the physician should counsel the patient on all options, provide thorough informed consent, offer contact information for the patient to pursue a second opinion or a radiation oncology referral, and ensure safe transfer of care should the patient desire treatment with a different provider.

Background

The efficacy and safety of biologic and phototherapy in treating moderate-to-severe psoriasis is well known. However, some patients may not respond well to biologic agents or phototherapy on their own and may require combination therapy. Skillfully combining a biologic agent and phototherapy may provide an additive improvement without much increase in risks.

Objective

To summarize the current state of evidence for the efficacy and safety of combining biologics with phototherapy in the treatment of moderate-to-severe plaque psoriasis.

Methods

We conducted an extensive search on Pubmed database for English language literature that evaluated the use of a combination of biologic and phototherapy for the treatment of moderate-to-severe psoriasis through January 2016. The search included the following key-words: psoriasis, etanercept, adalimumab, infliximab, ustekinumab, biologics, phototherapy, and combination therapy.

Results

The primary literature included randomized controlled trials, a head-to-head study, open-label controlled and uncontrolled trials, case series, and case reports. Etanercept was used in over half of the reported cases, but other biologic agents used included ustekinumab, adalimumab, and infliximab. The vast majority of phototherapy was narrowband ultraviolet B (NBUVB) radiation. Most cases reported enhanced improvement with combination therapy. Serious adverse events throughout the study duration were reported in <3% of the patients. Long-term adverse events cannot be excluded.

Conclusion

Combination of biologic and phototherapy appears to be a viable clinical strategy in the treatment of moderate-to-severe psoriasis not responsive to monotherapy, despite limitations in the data available. NBUVB in combination with biologics appears to be especially effective. However, the long-term impact of these combinations is yet to be determined.
