Filter by:The purpose of the study is to investigate the ability of mass spectrometry imaging to locate aggregates of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) ex-vivo, and to distinguish areas containing these carcinomas from normal skin. It is suggested that non-melanoma skin cancer (NMSC) cells show a different profile of endogenous lipids than healthe skin tissue which can be used as identifying biomarkers. If that hypothesis is correct it will be possible in the future to develop real-time tissue diagnosis and treatment of NMSC using mass spectrometry guided surgery. Method between 60 and 100 patients with BCCs, SCCs, and actinic keratoses (AK) will be recruited. For patients referred for Mohs surgical procedure at the Department of Dermatology, Bispebjerg Hospital, to treat BCCs or SCCs, three skin sections (5-10 um thick) of the tissue that is already removed will be use in our study. One section will be HE stained so we know exactly where the regions of interest are. Two sections will be used for MS analysis (MSI spectrum and REIMS spectrum). When patients are referred for a procedure to have treated several actinic keratoses (grade 1, 2 or 3) at Department of Dermatology, Bispebjerg Hospital we will take an extra punch biopsy (2-4 mm) depending on the size of the lesion. The biopsy is embedded and sectioned. We will use 3 skin sections (5-10 um thick) we will again use one section for HE staining and two for MS analysis. Multivariate statistical analysis will be performed on all mass spectra using Matlab or similar program. Linear discriminant analysis will be used to identify spectral differences between pre-malignant, cancer and normal tissue. Classification performance will be recorded with a leave-one- patient- out cross- validation scheme.
The care of patients with high-risk cutaneous squamous cell carcinomas in the head-neck area is complex and requires a multidisciplinary approach. A key component in this care is the need and experience of patients. However, studies on the experiences and needs of patients with high-risk cutaneous squamous cell carcinomas in the head-neck region are lacking.
The purpose of this study is to investigate the association between time to treatment (defined as date of pathological diagnosis to date of start treatment) and disease free survival in patients with high risk cutaneous squamous cell carcinoma in the head-neck region.
Americans who work outdoors are exposed to an extreme amount of solar ultraviolet radiation over a lifetime that substantially increases their risk for developing skin cancer. In Phase I, the feasibility of a virtual learning environment (VLE) for distributing the effective Sun Safe Workplaces (SSW) intervention to American employers will be established with input from senior managers and Hispanic and African American outdoor workers and development and evaluation of a prototype of the SSW Works VLE. In Phase II, the full SSW Works will be produced and tested for effectiveness at improving outdoor workers' sun protection in a randomized trial enrolling employers nationwide.
In this study, we compared a negative pressure wound therapy, versus a conventional dressing in order to evaluate the most efficient wound therapy closure after axillary and inguinal lymph nodes dissections in the management of metastatic skin tumors. A vacuum assisted closure therapy should prevent these comorbidities.
This study is to evaluate the psychological well-being in patients diagnosed with skin cancer (melanoma and Squamous Cell Carcinoma (SCC) in the face) at the time of diagnosis and after treatment. Patients diagnosed with primary melanoma and/or SCC and/or infiltrative basal cell carcinoma on the face subjected to surgical treatment (excision or Mohs Surgery) will be included. All patients will receive questionnaires.
This randomised controlled trial will investigate the role of melanoma surveillance photography (MSP) in the surveillance of patients at high or ultra-high risk of melanoma. MSP is a comprehensive method of melanoma monitoring which includes total body photography and digital dermoscopy which is performed at prescribed intervals. The study will test whether participants under surveillance with MSP have less unnecessary biopsies (false positives) compared to those without MSP. Participants will be Australian residents with a new diagnosis of primary melanoma, who have multiple naevi and are at high or ultra-high risk of developing melanoma. Participants will be randomised 1:1 to either groups. It is hypothesised that those randomised to surveillance with MSP will have better patient outcomes. Improved diagnostic performance as measured by the number of unnecessary biopsies will be the primary outcome measure.
A unique approach for cancer treatment employing intratumoral diffusing alpha radiation emitter device for superficial cutaneous, mucosal or soft tissue neoplasia
Comprehensive approaches that combine sun protection policy and education for outdoor workers can reduce their risk for skin cancer by reducing their exposure to solar ultraviolet radiation on the job. To effectively disseminate the investigators' evidence-based sun protection policy and education intervention, Sun Safe Workplaces, a balance of effectiveness and cost of scale-up methods is required. The investigators propose to translate the intervention using a technology-based delivery method and compare the cost effectiveness of the original intervention and the intervention delivered by technology in a study that models national distribution strategies to public safety and public works sectors.
The purpose of this study is to test the effectiveness, safety, and tolerability of the drugs nivolumab plus ipilimumab with or without the addition of stereotactic body radiation therapy (SBRT). Nivolumab is an antibody (a type of human protein) that is being tested to see if it will stimulate the body's immune system to work against tumor cells. This study will test an investigational use of nivolumab.
