Patrick Kishi, Cynthia J Price
A 67-year-old man developed a suspected adverse drug reaction during treatment with topical 5-fluorouracil (5-FU) for multiple actinic keratosis of the face, neck, and forearms. The man received topical 5-FU at a dosage of 0.5% for the actinic keratoses. After 1 week, he developed extreme lethargy, fatigue, fever, and mouth erosions. Several days later, and after discontinuation of 5-FU, painful mucositis and systemic side effects occurred, meeting criteria for hospitalization because of dehydration and a 6...

Few satisfactory treatment options are available for widespread areas affected by multiple actinic keratoses (AKs). Our primary objective was to assess the response rate to weekly 5-fluorouracil (5-FU) chemowraps on widespread AK lesions, and secondarily to assess tolerability, the percentage of patients with recurrence and time to recurrence, the response rate for patients with associated Bowen's disease (BD), and the percentage of squamous cell carcinomas (SCCs) identified after treatment. We conducted an open study which included all the patients who had been treated with weekly 5-FU chemowraps in our department over the course of five years for areas of widespread AKs...

BACKGROUND: The most widely used topical agents for the field-based treatment of multiple actinic keratoses (AKs) are 5-fluorouracil and imiquimod, but their comparative effectiveness has not been assessed in a real-world setting. OBJECTIVE: We compared the effectiveness of 5-fluorouracil and imiquimod in reducing risk of subsequent AKs in a large, integrated healthcare delivery system in Northern California. METHODS: In this cohort study, we identified adult health plan members that had an AK diagnosed in 2007 and subsequently filled a prescription for 5-fluorouracil or imiquimod (n=5,700)...

INTRODUCTION AND OBJECTIVES: Imiquimod is an excellent option for patients with actinic keratosis, although its use may be limited by the long course of treatment required (4 weeks) and the likelihood of local skin reactions. The objectives of the present study were to demonstrate the effectiveness of a 12-day course of imiquimod 5% for the treatment of actinic keratosis and to examine the association between treatment effectiveness and severity of local reactions. PATIENTS AND METHODS: We included patients with at least 8 actinic keratoses treated with imiquimod 5% cream for 12 consecutive days...

BACKGROUND: Actinic keratoses (AK) arise on sun-exposed regions of the skin. If left untreated, AK may progress to invasive squamous cell carcinoma (SCC), although the rate of progression is low. A practical treatment algorithm for the treatment of AK in standard situations has been published by the AKTeam™ expert panel. However, management of particular situations of AK with increasing/higher carcinoma risk or AK progressing into carcinomas with increased aggressiveness due to their anatomical location (risky areas), or in patients with an increased risk of SCC requires further discussion...

OBJECTIVE: To evaluate the ability of two-step irradiance to maintain pain control during red light 5-aminolevulinic acid (ALA) photodynamic therapy (PDT) for actinic keratoses (AK) and assess factors influencing pain. BACKGROUND: PDT provides excellent clinical and cosmetic results in the treatment AK and early basal cell carcinomas (BCC). Widespread use of PDT is limited, in part, by pain. A two-step irradiance method for PDT has previously been shown to significantly reduce PDT-associated pain during the treatment of BCC, but the ability of this method to limit pain during the treatment of AKs has not been reported...

Daylight photodynamic therapy (dl-PDT) is as effective as conventional PDT (c-PDT) for treating actinic keratoses but has the advantage of reducing patient discomfort significantly. Topical dl-PDT and white light-PDT (wl-PDT) differ from c-PDT by way of light sources and methodology. We measured the variables associated with light dose delivery to skin surface and influence of geometry using a radiometer, a spectral radiometer and an illuminance meter. The associated errors of the measurement methods were assessed...

BACKGROUND: Histological examination is the gold standard for actinic keratosis diagnosis; however, it is not always a feasible approach. Reflectance confocal microscopy (RCM) is a non-invasive technique that may be an alternative for monitoring actinic keratoses treatment response. Topical 5-fluorouracil is indicated for actinic keratosis multiple lesions and for field cancerization treatment. OBJECTIVES: To assess the RCM accuracy, sensibility and specificity for actinic keratosis, considering as a gold-standard the histopathological examination; as well as to evaluate the efficacy of 5% 5-fluorouracil treatment...

Andrés Már Erlendsson
Non-melanoma skin cancer is the most frequently occurring cancer in Caucasians today. Incidence rates in Europe have increased steadily since the 1960s and more than tripled over the last 50 years. Despite primary preventative efforts, incidences of non-melanoma skin cancer continue to rise and development of effective chemopreventative strategies is needed. In 2013, ingenol mebutate was approved in Denmark as a new topical drug for field-directed treatment for actinic keratoses. Ingenol mebutate has a dual mechanism of action, causing initial cell death, followed by an immune activation...

BACKGROUND: Photodynamic therapy with daylight (DL-PDT) is efficacious in treating actinic keratosis (AK), but the efficacy of field-directed, repetitive DL-PDT for the treatment and prophylaxis of AK in photodamaged facial skin has not yet been investigated. METHODS/DESIGN: In this multicenter, prospective, randomized, controlled, two-armed, observer-blinded trial, patients with a minimum of 5 mild-to-moderate AK lesions on photodamaged facial skin are randomly allocated to two treatment groups: DL-PDT with methyl aminolevulinate (MAL) and cryosurgery...

BACKGROUND: Actinic keratoses (AKs) prevalence was estimated at 39.5 million Americans in 2004, and the cost to treat AKs that year was approximately 1 billion dollars. Photodynamic therapy (PDT) is an FDA-approved therapy for the treatment of AK. Recent studies have focused on reducing PDT treatment time while maintaining efficacy. OBJECTIVE: To investigate the use of thermal modulation to improve the efficacy of ultra short aminolevulinic acid (ALA) incubation PDT...

BACKGROUND: Actinic keratoses (AKs) are proliferations of abnormal keratinocytes, which may progress into non-melanoma skin cancers. Although multiple treatment modalities exist for AKs, their incidence continues to rise, making new methods of both prevention and treatment necessary. DNA repair enzymes have been shown to reverse sun-damage, resulting in reduced rates of AKs and non-melanoma skin cancer (NMSC) in specific patient populations. OBJECTIVE: We investigated the efficacy of a topical DNA repair enzyme lotion as a field therapy for AKs...

Non-melanoma skin cancer (NMSC) is the most common malignancy of the light-skinned population with an enormous socioeconomic impact. Historically known as incurable under the term noli me tangere (transl. do not touch me), today various non-melanocytic cutaneous neoplasms are grouped as NMSC. The most common of these, basal cell carcinoma, squamous cell carcinoma and actinic keratoses as carcinomas in situ, are increasingly called keratinocyte carcinoma. Today, the pathogenesis and risk factors of NMSC are relatively well understood, which has led to multiple treatment options, the recognition of NMSC as an occupational disease in Germany and a variety of prevention approaches...

BACKGROUND: Ingenol mebutate gel 0.05% once daily for two consecutive days provides high clearance rates for actinic keratosis on a 25cm(2) area of the chest. However, it may cause intense local skin responses. OBJECTIVE: The objective of this study was to determine whether a lower dose of ingenol mebutate gel 0.015% could clear actinic keratosis on the chest with acceptable tolerability and a possible beneficial effect on photodamage and cosmesis. DESIGN: This was a noncomparative, open-label study (NCT02446223)...

INTRODUCTION: Daylight PDT (DLPDT) is a new PDT procedure. Several trials demonstrate that DLPDT achieves similar response rates with conventional PDT (CPDT) in the treatment of nonhyperkeratotic actinic keratoses (AKs) in a nearly painless way. It seems that DLPDT represents a more convenient and equally effective treatment modality. Data on long-term efficacy of DLPDT are limited. OBJECTIVE: To compare short- and long-term efficacy, safety and tolerability of DLPDT with that of CPDT in face and scalp AKs...
