BACKGROUND: Topical methyl-aminolevulinate photodynamic therapy (MAL-PDT) with 3 hours incubation is recommended as a field directed treatment. Skin pretreatment with ablative CO2 fractional laser (AFXL) prior to MAL-PDT enhances drug penetration and could minimize incubation time. OBJECTIVES: To evaluate and compare the safety and the preventive effect in the development of new non-melanocytic skin cancers (NMSCs) of AFXL-assisted MAL-PDT with one hour incubation with that of conventional MAL-PDT in patients with clinical and histological signs of field cancerization...

BACKGROUND: Topical methyl aminolevulinate photodynamic therapy (MAL-PDT) is highly effective for the treatment of superficial basal cell carcinoma (sBCC). Current European treatment protocol requires two hospital visits, which is costly and unpractical. The aim of this study was to evaluate the efficacy of fractionated MAL-PDT, using two light fractions at 3 and 4 hours compared to illumination at 3 and 5 hours after MAL-application. METHODS: Thirty patients were randomized into two groups...

BACKGROUND: Actinic keratoses (AK) are proliferations of neoplastic keratinocytes in the epidermis resulting from cumulative exposure to ultraviolet radiation (UVR), which are liable to transform into squamous cell carcinoma (SCC). Organ Transplant Recipients (OTR) have an increased risk of developing SCC as a consequence of long-term immunosuppressive therapy. The aim of this study was to determine the molecular signature of AKs from OTR prior to treatment with methyl aminolevulinate-photodynamic therapy (MAL-PDT), and to assess what impact the treatment has on promoting remodeling of the photo-damaged skin...

REVIEW
Colin A Morton, Lasse R Braathen
Topical photodynamic therapy (PDT) using daylight is effective in the treatment of actinic keratoses (AKs), offering the potential for treatment of large fields such as full face and balding scalp, but with minimal therapy-associated pain. Comparison with conventional PDT indicates similar efficacy for thin and moderate-thickness AKs, but with significantly less discomfort/pain, driving a patient preference for daylight-mediated PDT (DL-PDT) compared with conventional PDT using high-intensity office/hospital-based light sources...

Clinical Question: Are light therapies effective and safe for treating acne? Bottom Line: The evidence for all light therapies remains weak and inconclusive. Red-light methyl aminolevulinate-photodynamic therapy (MAL-PDT) was the only treatment associated with a small though clinically insignificant reduction in the number of inflamed lesions and in global improvement as assessed by an investigator in moderate to severe acne. Red-light MAL-PDT was not associated with higher rates of severe adverse effects than placebo or no treatment...

BACKGROUND: Basal cell carcinoma (BCC) represents the most common non-melanoma skin cancer worldwide affecting mainly adult, fair-skinned individuals. The WHO distinguishes aggressive and non-aggressive forms of which prototypical variants of the latter are primary nodular and superficial BCC. OBJECTIVES: To demonstrate non-inferiority of BF-200 ALA (a nanoemulsion gel containing 5-aminolaevulinic acid) compared to MAL (a cream containing methyl-aminolevulinate) in the treatment of non-aggressive BCC with photodynamic therapy (PDT)...

Photodynamic therapy (PDT) with topical 5-aminolevulinic acid (ALA) or methyl aminolevulinate (MAL) has proven to be a highly effective conservative method for the treatment of actinic keratosis (AK), Bowen's disease (BD), and superficial basal cell carcinoma (sBCC). PDT is traditionally performed in association with broad-spectrum continuous-wave light sources, such as red or blue light. Recently, intense pulsed light (IPL) devices have been investigated as an alternative light source for PDT in the treatment of nonmelanoma skin cancers (NMSC)...

OBJECTIVE: We treated two patients with recalcitrant lichen sclerosus (LS) of the penis with a combination of 1927 nm thulium fiber laser and methyl-aminolevulinate (MAL) photodynamic therapy (PDT). BACKGROUND DATA: Therapy of LS is based on topical potent steroids, emollients, and topical calcineurin inhibitors. Circumcision is effective, but not always accepted. PDT represents a valid therapeutic option in refractory cases, but there are no reports about the association with 1927 nm thulium laser in the treatment of this pathology...

Photodynamic therapy (PDT) has received high attention in cancer treatment due to its minimal side effects, specific cancer-targeting, non-invasion and low cost. It utilizes a specific group of anti-cancer drugs called photosensitizers (PS), which can be only activated under a certain wavelength light illumination and kills cancer cells. To screen the potential of PS and setup of PDT treatment protocol, it is essential to assess the PDT efficacy in vitro. In this study, a light-emitting diode- (LED-) based illumination system at two wavelengths (red & blue) with homogeneous and stable irradiation, and constant temperature conditions in 96-well plates was provided...

PDT is widely applied for the treatment of non-melanoma skin cancer pre-malignant and malignant lesions (actinic keratosis, basal cell carcinoma and in situ squamous cell carcinoma). In photodynamic therapy (PDT) the interaction of a photosensitizer (PS), light and oxygen leads to the formation of reactive oxygen species (ROS) and thus the selective tumor cells eradication. Xeroderma pigmentosum (XP) and Gorlin-Goltz Syndrome (GS) patients are at high risk of developing skin cancer in sun-exposed areas. Therefore, the use of PDT as a preventive treatment may constitute a very promising therapeutic modality for these syndromes...

For the treatment of superficial basal cell carcinoma, a prospective, noninferiority, randomized controlled multicenter trial with 601 patients showed that 5% imiquimod cream was superior and 5-fluorouracil cream not inferior to methyl aminolevulinate photodynamic therapy (MAL-PDT) at 1 and 3 years after treatment. No definite conclusion could be drawn regarding the superiority of imiquimod over 5-fluorouracil. We now present the 5-year follow-up results according to the intention-to-treat analysis. Five years after treatment, the probability of tumor-free survival was 62...

BACKGROUND: Basal cell carcinoma (BCC) is the most common type of skin cancer and incidence rates are increasing. Photodynamic therapy (PDT) is a frequently used treatment, especially for superficial BCC (sBCC). Two topical photosensitizing agents are currently used to treat sBCC, namely 5-aminolaevulinic acid (ALA) and its ester, methyl aminolaevulinate (MAL). Previous research showed a high efficacy for ALA-PDT using a twofold fractionated illumination scheme in which two light fractions of 20 J cm-2 and 80 J cm-2 were delivered 4 h and 6 h after ALA application...

Several immune-related markers have been implicated in basal cell carcinoma (BCC) pathogenesis. The BCC inflammatory infiltrate is dominated by Th2 cytokines, suggesting a specific state of immunosuppression. In contrast, regressing BCC are characterized by a Th1 immune response with IFN-γ promoting a tumor suppressive activity. IL-23/Th17-related cytokines, as interleukin (IL)-17, IL-23 and IL-22, play a significant role in cutaneous inflammatory diseases, but their involvement in skin carcinogenesis is controversial and is poorly investigated in BCC...
