Using MC1R Genotype to Impact Melanoma Risk Behavior
Melanoma (Skin)Squamous Cell Carcinoma4 moreThe purpose of this study is to examine how different messages about risk of melanoma can impact the way people protect themselves against developing these diseases.
French National Database of Rare Dermatological Cancers
Adnexal Tumor of SkinMerkel Cell Carcinoma1 moreMerkel cell carcinoma, advanced basal cell carcinoma requiring systemic treatment, and cutaneous adnexal carcinomas are 3 types of rare skin cancers for which much remains unknown in terms of natural behavior, prognosis, treatment and outcomes. CARADERM is a French prospective national cohort enrolling patients with either one of these 3 tumor types, whose objectives are : to provide epidemiological, clinical and socio-economic characteristics of patients to identify new clinical or epidemiological prognostic factors for these rare cancers to evaluate the impact of various treatments on outcomes
Structural Description of Skin Biopsies With Dynamic Full-field Optical Coherence Tomography on...
Basal Cell CarcinomaTomography1 moreBasal cell carcinoma (BCC) are the most frequent skin cancers. Their incidence is constantly increasing. BCC diagnosis is first clinically suspected and then confirmed following histological examination of either a skin biopsy or the excisional specimen. Surgery is the first-line treatment and some procedures (notably Mohs surgery) require extemporaneous histological analysis of the edges to ensure a complete excision. Such on-site histopathological examination can be time consuming and associated with decreased sensitivity. Skin imaging techniques have already been tested to overcome these limitations and seem promising. Although some of them - such as confocal microscopy - are already even used in vivo, there is to date no report of the use of full-field optical coherence tomography for the diagnosis of BCC. The DOCTOBA study intends to describe direct histopathological examination of fresh skin biopsy or excisional specimen with dynamic full-field optical coherence tomography.
Curettage Versus Excision in Nodular and Superficial Basal Cell Carcinomas
CarcinomaBasal CellBasal cell carcinoma (BCC) is the most frequent skin cancer. Uncontrolled growth destroys local anatomic structures. There are various treatment alternatives with different recurrence rates and expenses. After surgical excision, the recurrence rate is in between 3 and 4% and the procedure is relatively expensive. Photodynamic therapy as well as imiquimod 5% are expensive therapies with high recurrence rates, that lack histologic evidence of BCC. Cryosurgery and curettage are inexpensive, although the recurrence rates are higher than after surgical excision. This prospective, randomized trial compares recurrence rates, cosmetic outcome, and surgery-related complications after curettage versus surgical excision in nodular and superficial BCC. About 600 tumors will be included. One half is treated by curettage, the other half by surgical excision. The follow-up period is four years. If the difference between recurrence rates is ≤7% and the cosmetic outcome as well as the surgery-related complications are not worse after curettage, surgical excision must be considered an overtreatment.
Complications and Recurrences After Mohs Micrographic Surgery and Slow Mohs
Skin CancerComplication8 moreMohs micro-graphic surgery (Mohs) is a tissue-sparing, surgical treatment for different types of skin cancer (e.g. basal cell carcinoma, squamous cell carcinoma, lentigo maligna (melanoma). It is a procedure performed with frozen sections. Slow Mohs, a variant of micro-graphic surgery, is performed by formalin fixation and paraffin-embedded sections. Both in Mohs and Slow Mohs tumor margins are assessed to achieve complete removal. This study aims to investigate the clinical presentation and outcomes (i.e. complications and recurrence rates) in patients treated with Mohs or Slow Mohs in the dermatology department of the Maastricht University Medical Center+ in Maastricht, the Netherlands.
Pathological Characteristics of Basal Cell Carcinoma
Dermatological TumorsA hospital based cross-sectional study was conducted from 2017 to February 2021. Clinical history, examination and histopathological variants were collected from medical files and pathology reports. Confirmation of pathology was done in all the patients visiting skin and plastic surgery department with suspected lesions.
Ex-vivo Examination of Excisions of Skin Tumors by Confocal Optical Coherence Tomography (LC-OCT)...
Cutaneous TumorOptical Coherence Tomography3 moreThis project aims to validate ex vivo the use of the OCTAV® prototype integrating the "dermoscope" function before an in vivo application, by comparing images obtained by the OCTAV® prototype integrating the "dermoscope" function with the histological sections of a skin tumor excision corresponding to them exactly, at the same level.
Familial Investigations of Childhood Cancer Predisposition
Acute LeukemiaAdenomatous Polyposis44 moreNOTE: This is a research study and is not meant to be a substitute for clinical genetic testing. Families may never receive results from the study or may receive results many years from the time they enroll. If you are interested in clinical testing please consider seeing a local genetic counselor or other genetics professional. If you have already had clinical genetic testing and meet eligibility criteria for this study as shown in the Eligibility Section, you may enroll regardless of the results of your clinical genetic testing. While it is well recognized that hereditary factors contribute to the development of a subset of human cancers, the cause for many cancers remains unknown. The application of next generation sequencing (NGS) technologies has expanded knowledge in the field of hereditary cancer predisposition. Currently, more than 100 cancer predisposing genes have been identified, and it is now estimated that approximately 10% of all cancer patients have an underlying genetic predisposition. The purpose of this protocol is to identify novel cancer predisposing genes and/or genetic variants. For this study, the investigators will establish a Data Registry linked to a Repository of biological samples. Health information, blood samples and occasionally leftover tumor samples will be collected from individuals with familial cancer. The investigators will use NGS approaches to find changes in genes that may be important in the development of familial cancer. The information gained from this study may provide new and better ways to diagnose and care for people with hereditary cancer. PRIMARY OBJECTIVE: Establish a registry of families with clustering of cancer in which clinical data are linked to a repository of cryopreserved blood cells, germline DNA, and tumor tissues from the proband and other family members. SECONDARY OBJECTIVE: Identify novel cancer predisposing genes and/or genetic variants in families with clustering of cancer for which the underlying genetic basis is unknown.
To Assess The Efficacy And Safety Of Vismodegib And Radiotherapy In Advanced Basal Cell Carcinoma...
CarcinomaBasal CellThis is a Fleming-A' Hern, single arm, multicenter, no-profit, phase II study of radiotherapy and Vismodegib in adult patients with high risk or locally advanced basal cell carcinoma not amenable to radical surgery cell carcinoma (BCC) (comparator: not applicable). The recruitment period is expected to be approximately 24 months. The trial will consist of a Screening/Baseline period (Day -28 to -1), a Treatment Period when patients will be treated with radiotherapy (4 weeks) followed by Vismodegib 150 mg/die continuously for six cycles (24 weeks). The study will end 14 months after start of treatment of the last patient enrolled and evaluable according to primary end point.
