Are there any situations in which you would treat a cutaneous in-situ squamous cell carcinoma of the head and neck with radiation?
Primary radiotherapy (RT) is generally not indicated for carcinoma in-situ (CIS) or pre-invasive malignancies for which surgical resection aimed at achieving negative margin is the mainstay approach. Even if the patient were inoperable or the tumor was unresectable (two distinct scenarios), active s...
What circumstances would drive you to consider using an oral IL-23 inhibitor over parenteral options for the management of psoriasis and/or psoriatic arthritis?
Psoriatic arthritis is a heterogeneous disease and the choice of therapy is driven by many factors.The most important factors in the decision tree are whether the patient has 1) axial disease and/or 2) severe psoriasis.Additional Considerations include: prior therapies, extramusculoskeletal manifest...
How do you approach postoperative radiation therapy in a patient with head and neck cancer who has high risk of recurrence in the setting of active epidermolysis bullosa?
Epidermolysis bullosa is a rare genetic entity characterized by collagen mutations affecting the attachment of epithelial cells to the basement membrane of the skin and mucosa, manifesting in blistering and non-healing skin wounds and mucosal strictures in the GI tract. There is a risk of non-healin...
How should medical oncologists and dermatologists communicate about patients with at least Stage IIB/III cutaneous melanoma regarding neoadjuvant immunotherapy?
Only melanoma patients with stage III or resectable stage IV disease should be treated with standard-of-care neoadjuvant immunotherapy. These patients should see a medical oncologist first (and no longer last, as is the current process). I would recommend that the schedulers at your institution be e...
In what situations would you recommend adjuvant radiation therapy for patients with locally advanced and/or recurrent basal cell carcinoma that receive vismodegib followed by surgery?
Adjuvant radiation therapy should be considered for locally advanced basal cell carcinomas when surgical margins are positive, or when there is perineural invasion, particularly in high-risk anatomical locations such as the face. This recommendation is endorsed by both the NCCN and the American Acad...
How would you approach the radiation treatment of multiple recurrent lentigo maligna on the sole of the foot in an active patient not desiring further surgery?
While surgery remains the gold standard in the management of lentigo maligna (LM), radiotherapy has been used for decades as an alternative, particularly in those patients with surgical comorbidities or where surgery may result in poor functional or cosmetic outcomes. Additionally, radiotherapy is o...
Would you give lung SBRT to a patient with bullous pemphigoid on the chest and torso?
If this patient has a clinically relevant lung cancer (which, by the clinical description, it sounds like it is felt they do) then I would feel comfortable treating them with SBRT. The very focal nature of SBRT makes this a very different scenario than large-field radiation. There is minimal data ov...
Is there a role for phenotyping patients with CSU outside of a research setting by ordering IgG-anti-TPO, IgG-anti-FceRI , total IgE, total IgA etc.?
I do think it can be helpful in patients who have difficult-to-control disease. Many of these (e.g. IgG-anti-TPO, total IgE, anti-thyroglobulin antibody) have been shown to help predict responsiveness to omalizumab treatment or have been associated with disease activity (Højgaard Pedersen et al., PM...
Would you be comfortable using isotretinoin in a female teenage patient who has a history of depression that is now stable but with a prior suicide attempt two years ago?
Yes. There is ample evidence that isotretinoin does not cause depression. In the large Canadian study, there was a slightly negative association with suicide. As the good doctors noted above, using appropriate step therapy, with informed consent (especially regarding pregnancy and birth defects), is...
What’s your immediate post-procedure protocol for fractionated laser resurfacing (i.e., Sciton Pro-fractional Laser)?
My immediate post procedure protocol for fractionated laser resurfacing is to decrease stinging with the Zimmer chiller (approximately 10-30 minutes followed by the application of Vaseline. I have not seen significant pinpoint bleeding while treating acne scarring (Lumenis Encore laser) but have see...
