Filter by:Superficial basal cell carcinoma (sBCC) can be treated non-invasively, but follow-up is necessary because lesions can reoccur. This study aims to evaluate the additional value of optical coherence tomography (OCT) for the detection of recurrent BCC lesions, that may remain unrecognized by clinical and dermoscopic examination (CDE). This study compared the diagnostic accuracy of CDE and CDE combined with OCT for detection of recurrent basal cell carcinoma (BCC) after non-invasive treatment of sBCC.
Locally advanced basal cell carcinoma (BCC) are large BCCs or BCCs located in areas subject to functional and aesthetic risk following surgery or radiotherapy. In these particular situations, surgery and radiotherapy are sometimes not appropriate, and Sonic Hedgehog inhibitors (SHHi) (Vismodegib and Sonidegib) can be proposed. SHHi are effective treatments in laBCC but most CR patients discontinue treatment because of tolerability. Approximately 65% of the population experience a relapse after discontinuation. A few cases of patients treated concomitantly by radiotherapy and vismodegib have been reported in the literature, suggesting that combining vismodegib and concomitant radiotherapy results in an improved overall response compared to a single modality treatment. There is no study evaluating a "consolidation radiotherapy" after complete response to SHHi. We carry out a prospective multicenter study in order to evaluate consolidation radiotherapy in patients with laBCC after achieving complete response with SHHi, with the hypothesis of reducing recurrence after discontinuation of SHHi.
Vitamin D has a crucial role in cancer control and prevention.vitamin D receptor (VDR) and its heterodimer Retinoid X receptor (RXR) are equally important in the cell. This ligand (vitamin D) and receptors (VDR-RXR) complex together triggers downstream DNA damage response in the cell. Retinoid receptors are a superfamily of nuclear receptors. The preferred receptor that attaches to VDR is RXR, with its subunits α, β and γ. RXR α is more frequent in the skin than other tissues, while β occurs in internal organs and γ is frequently related to neural disorders. the investigator hopes to assess prognosis of SCC & BCC by using RXR-α biomarker & attempts to use it in the treatment.
The purpose of this study is to find out more about how Basal Cell Carcimonas/BCCs grow and to learn more effective ways to monitor and treat these common cancers. This study will not provide any type of treatment for the participants' cancer; it is a 3-year observational study to monitor participants' cancer.
Background: Oral hedgehog inhibitors vismodegib and sonidegib have been used for the treatment of locally advanced (laBCC), metastatic basal cell carcinoma (mBCC) and in basal cell nevus syndrome (BCNS) patients. In the Netherlands, targeted therapy with vismodegib and sonidegib has been available since 2013 and 2021, respectively. No direct comparative studies have been performed between the two oral hedgehog inhibitors (HHI) vismodegib and sonidegib yet . In addition, data for sonidegib are not yet available. Objective: The aim of this study is 1) to evaluate the effectiveness of oral HHIs in the treatment of laBCC, mBCC and BCNS patients and 2) to compare the oral HHIs vismodegib and sonidegib. Study design: prospective registration study that includes all patients, regardless of age and gender, with histologically proven basal cell carcinoma receiving treatment with either vismodegib or sonidegib in the Netherlands. Patient, tumor and treatment information was gathered from patient records. Main study parameters/endpoints: The primary outcome for measuring efficacy/tumor response was median progression free survival (PFS) where the decrease, stagnation or increase in tumor size is measured by maximum diameter. Secondary outcomes are frequency, severity and reversibility of treatment-emergent adverse events and disease-specific quality of life expressed as mean scores on the EORTC-QLQ-C30 and aBCCdex questionnaires.
A Multicenter, Prospective, Low-interventional Clinical Study Evaluating on mobile application validation ("ProRodinki") in assessing the risk of skin malignant neoplasms
The investigators will compare the application of two different creams for the treatment of low-risk skin cancers-superficial basal cell carcinoma (sBCC) and squamous cell carcinoma in situ (SCCis). 5-Fluorouracil cream is currently FDA approved for the treatment of superficial basal cell carcinoma and is routinely used by dermatologists across the country and at Boston Medical Center (BMC) for SCCis. The normal treatment regimen is 4 weeks of the 5-fluorouracil cream for both skin cancers. The application of a compounded cream consisting of 1:1 ratio 5-fluorouracil with calcipotriene will be tested. This combination cream has been shown to clear pre-skin cancers called actinic keratoses and prevent future skin cancers from developing. This combination cream for 7-14 days to see if this shorter treatment course provides clearance of the 2 types of skin cancer. This combination cream is successfully used in this manner to treat other subtypes of related skin cancers. This will be a pilot study with The primary endpoint for this pilot randomized single blinded clinical trial will be the response to treatment (yes versus no). The lesions will be assessed clinically for clearance of cancer, as would normally be done and is consistent with how comparable studies have assessed clearance. Participants will be followed closely afterwards for three years with visits at 6 months, which does not vary from standard practice. If the lesions are not clear of cancer or equivocal clinically, the lesions will be re-biopsied and normal standard of care procedure will take place.
This 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.
Phase II, open label, multicentric, proof-of-principle basket trial in patients with malignant tumors of the skin amenable to intratumoral injection, and in a curative or neoadjuvant or palliative intention.
The aim of this study is to show that the Nd:YAG laser could be a promising alternative treatment option in the management of low-risk basal cell carcinomas with similar high efficacy rates to surgery, and low recurrence rates evaluated over a time period of one year. Reflectance confocal microscopy, optical coherence tomography and clinical examination are used prior to confirm the clinical diagnosis of the basal cell carcinoma and for premargination of the tumor. The optical coherence tomography will also be used post treatment to confirm clearance of the basal cell carcinoma and to monitor treatment response.
