BACKGROUND: Non-melanoma skin cancer (NMSC) and actinic keratosis (AK) are very common among fair-skinned individuals. A disease continuum from AK to squamous cell carcinoma (SCC) has been frequently postulated. AK and NMSC may influence quality of life (QL) of patients, and it can be suspected that disease progression entails a QL reduction. The purpose of this study was to document QL in patients with NMSC and AK using the health-outcome questionnaire EQ-5D-5L. METHODS: The study was designed as a non-interventional, prospective, cross-sectional study...

BACKGROUND: Actinic keratoses (AKs) are commonly diagnosed clinically. Actinic keratosis area and severity index (AKASI) is a new easy-to-use tool to assess the severity of AK on the head. OBJECTIVE: To determine the association between chronically UV-induced tumours such as basal cell carcinomas (BCC) or squamous cell carcinomas (SCC) and AKASI. METHODS: We performed a retrospective analysis of patients who had undergone oncological surgery due to UV-induced tumours and who were assessed for AKASI and Physician's Global Assessment (PGA) prior to surgery...

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...

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...

Basal cell carcinoma (BCC) comprising several lesions is not uncommon, but nonsyndromic multiple BCCs with parotid invasion are rare entities. We present two cases of multiple sporadic, nonsyndromic BCCs, and one of these cases is a unique case of parotid invasion associated purely with actinic keratosis. In Case 1, a 79-year-old female presented with multiple skin lesions on the face and left hand. All lesions were completely removed by surgery. The pathologic results showed lesions consistent with BCC and some lesions consistent with actinic keratosis...

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...

In recent years, due to the development of nanotechnology new horizons in treatment and diagnosis of cancer open up. Development of nano-systems for simultaneous transfer of active substances and imaging of tumor regions gathers an important amount of scientific interest. This new category of nano-systems is called Theranostics. Theranostics methods can provide multiple benefits by inserting nanoparticles into the patient and using photodynamic therapy and pave the way for personalized medicine. The objective of this paper is to study the use and application of Theranostics in the diagnosis and treatment of cancer, in order to achieve personalized anticancer treatment...
