Active clinical trials for "Carcinoma, Basal Cell"

To readdress basal cell carcinoma (BCC) in the periocular region to prove histologically controlled surgical treatment efficacy and to identify high-risk characteristics.

The primary purpose for this multi-center, non-interventional study is to evaluate the duration of response defined as duration from first documented response of complete response (CR) or partial response (PR) until disease progression (as determined by the treating physician) for participants with laBCC.

This study aims establish the effectiveness of Image Analysing Algorithm (DERM) to identify melanoma, Squamous Cell Carcinoma (SCC) and Basal Cell Carcinoma (BCC) when used to analyse dermoscopic images of skin lesions within the US and European population.

This prospective study of 60 slides of basal and squamous cell carcinomas of the skin aims to determine whether: The process of cryofixation prior to generating formalin fixed paraffin embedded (FFPE) H&E sections alters the histology in skin tumor specimens. Which specific histologic parameters are altered between previously cryofixed versus routine FFPE sections. Histologic observations will be recorded by two dermatopathologists and two Mohs surgeons and statistically analyzed.

The aim of this study was to compare histologically observed tumour infitration of basal cell carcinoma (bcc) lesions before and after curretage.A significant reduction of tumour depth would enable further bcc's included for superficial non-invasive treatment modalities such as topical photodynamic therapy.

A multi-centre randomized non-inferiority trial investigating the (cost-)effectiveness of Optical Coherence Tomography (OCT) versus regular punch biopsy in the diagnosis and subtyping of Basal Cell Carcinoma (BCC).

A patient decision aid (PDA) was tested in a population of patients with superficial basal cell carcinoma. This study evaluates whether the use of a PDA improved outcomes like decisional conflict and knowledge.

The aim of this non-interventional study is to provide further data on the utilization, effectiveness, safety and clinical benefit including duration of response of Vismodegib for treatment of locally advanced basal cell carcinoma (laBCC), inappropriate for surgery or radiotherapy under real world clinical conditions.

The investigators hope to compare two different methods of closing skin wounds using sutures. One of these methods (the set-back technique) was recently described in 2010 and has been reported to be technically easier and reduces the chance of spitting sutures (deep sutures that are pushed to the surface of the skin as the wound heals). The other method (the vertical mattress technique) has been used for many years with good results. However, no controlled studies have been performed to clearly demonstrate a difference between the two methods. We hope to find differences in the height of the wound edges immediately after surgery(5 minutes following the procedure) as well as the appearance of the scar and symptoms associated with the scar 3 months after surgery.

The overall aim of this population-based screening study is to assess whether the skin cancer screening training of family physicians and dermatologists leads to improved screening outcomes. The training course aims to increase the accuracy of detecting early stages of skin cancer. Screening outcomes of an intervention region (Calgary, Canada) in which physicians receive training will be compared with screening outcomes of a control region (Edmonton, Canada) where no physician training is administered. The investigators will determine whether: clinical screening outcomes are more favorable in the group of trained physicians compared to non trained physicians there is an increase of knowledge about skin cancer screening among trained physicians, compared to non trained physicians skin cancer screenings are associated with psycho-social harms population-based screening has an effect on the overall incidence and stage-specific-incidence of skin cancer in Alberta The investigators are aiming to recruit 100 physicians per region (total of 200 physicians) who will screen 40,000 to 80,000 individuals over a period of 20 months.
