The purpose is to investigate the diagnostic value (sensitivity and specificity) of dermal-Optical Coherence Tomography (D-OCT, VivoSight Dx), in patients with clinically suspected BCC lesions inside the periocular region and compare these results to previous reports using D-OCT in diagnosing lesions outside the periocular area. The Hypotheses: - The sensitivity and specificity of D-OCT in diagnosing BCC inside the periocular region is comparable to previous reports on BCC lesions outside the periocular region when the standard D-OCT probe is used. - The sensitivity and specificity of D-OCT in diagnosing BCC inside the periocular region is increased when the customised D-OCT probe is used. - The sensitivity and specificity of D-OCT in diagnosing periocular BCC is comparable to punch biopsy when both standard and the customised D-OCT probes are used. - D-OCT with the 10 and 20-millimeter standoff is capable of subtyping periocular BCC. - The inter-observer variation in diagnosing and sub-typing periocular BCC decreases with increasing experience in the scanning procedure. - The number of scans to correctly interpret D-OCT decreases with increasing experience in the scanning procedure. - Delineation of periocular BCC tumour extension is possible using both D-OCT probes
The current gold standard for diagnosing basal cell carcinoma (BCC) is the histopathological examination of biopsy specimen. However, non-invasive imaging modalities such as optical coherence tomography (OCT) may replace biopsy if BCC presence and its subtype can be established with high confidence. Subtype differentiation is crucial; while superficial BCCs (sBCC) can be treated topically, nodular (nBCC) and infiltrative BCCs (iBCC) require excision. Dynamic OCT (D-OCT) is a functionality integrated within the OCT device, enabling the visualization of vascular structures through speckle variance. Descriptive studies have unveiled vascular shapes and patterns associated with BCC and its respective subtypes. These findings suggest that D-OCT could contribute to the accuracy of BCC detection and subtyping. Yet comparative clinical studies between OCT and D-OCT are lacking. In the proposed diagnostic cohort study, we aim to assess whether D-OCT assessment is superior to OCT in terms of accuracy for BCC detection and subtyping.
Basal cell carcinoma (BCC) is the most common form of cancer and entails approximately 80% of all cutaneous malignancies. This locally destructive neoplasm is commonly diagnosed by punch biopsy which is considered painful, causes procedural scarring and carries a small risk of infection and re-bleeding associated with invasive procedures. Moreover, awaiting the results of the subsequent histopathological examination causes treatment delay and can be stressful for the patient. The drawbacks of biopsy could be overcome by optical coherence tomography (OCT), a non-invasive diagnostic modality that may replace biopsy in up to 66% of patients. However, OCT assessors are scarce which hinders the implementation of OCT. This problem may be addressed by teledermatology in which remote OCT assessment by an assessor facilitates simultaneous assessment for multiple clinics. Remote OCT assessment withholds the OCT assessor from visually inspecting the lesion. But the effect of visual inspection on the diagnostic accuracy remains unknown and the question arises whether visual inspection is necessary for accurate OCT assessment. In this diagnostic case-control study we will determine whether distant OCT assessment without visual information on the lesion is non-inferior to distant OCT assessment with clinical and dermoscopic photographs (CDP-OCT).
This is a comparative, randomized, prospective, multicenter clinical investigation aimed at evaluating the efficiency and economic impact of LC-OCT (Line-field Confocal Optical Coherence Tomography) for the diagnosis and management of basal cell carcinomas.
Basal cell carcinoma (BCC) is the most prevalent form of cancer among the Caucasian population. There are several subtypes of BCC with different clinical characteristics and treatment strategies. Superficial and nodular BCCs are low-risk BCC subtypes. The diagnosis and subtype of BCC can be confirmed by means of punch biopsy, but non-invasive diagnosis by means of Optical Coherence Tomography (OCT) is proven to be a non-inferior alternative diagnostic instrument. Besides, non-invasive topical treatment is recommended as valuable treatment alternative to surgical excision for low-risk BCC. Since non-invasive diagnosis and treatment for low-risk BCC is being implemented into daily practice, we want to evaluate the real-world effectiveness of different invasive and non-invasive diagnostic and treatment strategies in the management of low-risk BCC. This real-world evidence will enhance our understanding of these management strategies for low-risk BCC in daily practice.
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 investigators want to assess the safety and efficacy of using intralesional 5-FU for the management of different types of BCC (including all the types EXCEPT the infiltrative one), by estimating different outcomes after the intralesional administration of 5-FU to BCC patient. Patients are randomly selected from the outpatient dermatologic clinic in the Aleppo University Hospital (AUH) over a period of 12 months and then these patients are followed up over another 12 months.
his is a Phase 2, Single-Arm, Open-Label, Single Center, to Assess Efficacy and Safety of Tirbanibulin Ointment 1% in Adult Subjects with superficial basal cell carcinoma (sBCC) not arising on the face or scalp
The aim of this clinical study is to find out how well Patidegib Gel 2% works in preventing new basal cell carcinomas (BCCs) developing on the face of adults with Gorlin syndrome, and how safe Patidegib Gel 2% is to use. Participants will apply either Patidegib Gel 2% or a Vehicle Gel (with no active drug substance) to their face twice a day for a year (12 months). The number of new BCCs on the face will be compared between participants who used Patidegib Gel 2% or Vehicle Gel after 12 months.
