    Expert Consensus on Cosmetic Outcomes After Treatment of Actinic Keratosis.
    J Drugs Dermatol 2017 Mar;16(3):260-264

    Dermatologists treat actinic keratosis (AK) primarily because these lesions have the potential to progress to invasive squamous cell carcinoma. Patients, on the other hand, generally seek treatment to remove the lesions and achieve an improved appearance of their skin following treatment. In selecting a treatment option for AK, dermatologists should consider post-treatment cosmesis, because cosmetic outcomes differ across AK treatments. Read More


    Regression Analysis of Local Skin Reactions to Predict Clearance of Actinic Keratosis on the Face in Patients Treated With Ingenol Mebutate Gel: Experience from Randomized Controlled Trials.
    J Drugs Dermatol 2017 Feb;16(2):112-114

    Ingenol mebutate gel, a topical field treatment for actinic keratosis (AK), elicits inflammatory application-site reactions in most patients.

    The importance of patient-centred care to overcome barriers in the management of actinic keratosis.
    J Eur Acad Dermatol Venereol 2017 Mar;31 Suppl 2:17-20
    Department of Cutaneous Medicine & Surgery, The Royal London Hospital & QMUL, Bart's Health NHS Trust, Whitechapel, London, UK.
    Visible actinic keratosis (AK) lesions and subclinical (non-visible) sun damage in the field of cancerization are associated with risk of both non-melanoma skin cancer, including basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), and, more rarely, melanoma. As the incidences of AK and skin cancer are increasing, effective prevention and treatment of AK is essential to minimize disease burden and improve patient quality of life. Currently, AK lesions are often left untreated and field therapies are underused. Read More

    The importance of treating the field in actinic keratosis.
    J Eur Acad Dermatol Venereol 2017 Mar;31 Suppl 2:8-11
    Klinik für Dermatologie, Venerologie und Allergologie, St. Josef-Hospital, Ruhr-Universität Bochum, Bochum, Germany.
    Actinic keratoses (AKs) are intraepithelial atypical proliferations of keratinocytes that develop in skin that has undergone long-term exposure to ultraviolet radiation. Given the ageing population and an increasing prevalence of AK, the socio-economic burden of AK is likely to rise over the coming years. Areas of subclinical (non-visible) sun damage in the periphery of visible AK lesions contain the same genetic changes as those found in the lesions themselves, and are known as areas of field cancerization.

    From actinic keratosis to squamous cell carcinoma: pathophysiology revisited.
    J Eur Acad Dermatol Venereol 2017 Mar;31 Suppl 2:5-7
    Hospital Universitari General de Catalunya-Grupo Quirón Salud, Universitat Autònoma de Barcelona, Barcelona, Spain.
    The precursor of most cutaneous invasive squamous cell carcinomas (iSCCs) is intraepithelial UV-induced damage, known as field cancerization, which can eventually transform into actinic keratosis (AK). Although AK is the most common precursor of iSCC, many AKs will either persist in the same stage or regress, while only a few will progress into iSCC. Nevertheless, because the progression of individual AKs cannot be predicted, it has been proposed that all AKs, regardless of the grade, should be carefully monitored and appropriately treated in clinical practice.

    Daylight photodynamic therapy vs. Conventional photodynamic therapy as skin cancer preventive treatment in patients with face and scalp cancerization: an intra-individual comparison study.
    J Eur Acad Dermatol Venereol 2017 Feb 21. Epub 2017 Feb 21.
    First Dermatology Department, Medical School, Aristotle University of Thessaloniki, Thessaloniki, Greece.
    Background: Individuals with medical history of non-melanoma skin cancers (NMSCs) usually develop multiple and/or recurrent malignant lesions around the site of the primary neoplasm. The latter represents the clinical expression of the 'field cancerization' theory; supporting the presence of multiple malignant clones of dysplastic keratinocytes over the entire epithelium that potentially can progress into clinical lesions. Taking into consideration that the burden of NMSCs on public health and health-care cost is high, adequate control of recurrences and management of field change is challenging. Read More
