Basal Cell Carcinoma

This retrospective observational study aims to develop and evaluate a convolutional neural network (CNN)-based artificial intelligence model for risk classification and histopathological subtype prediction of basal cell carcinoma (BCC) using clinical and dermoscopic images. Histopathologically confirmed BCC cases from a dermatology archive will be included. The primary objective is to assess the diagnostic performance of the CNN model in classifying BCC as low-risk or high-risk. Secondary objectives include predicting histopathological subtypes and comparing the model's performance with that of dermatology physicians. Histopathological diagnosis will serve as the reference standard. All archived data will be anonymized before analysis.

This research study is for people who have been diagnosed with a nonmelanoma skin cancer (either basal cell carcinoma or squamous cell carcinoma) and are planning to receive either Mohs surgery or ED\&C (electrodessication \& curettage) as part of clinical care. The purpose of this study is to understand how photodynamic therapy (PDT) with or without Vitamin D can promote an immune response to skin cancer. For this study, participants will be randomized (randomly assigned) and asked to take Vitamin D or placebo for 6 days and come to the clinic for a single PDT treatment 1-14 days prior to their surgery. At this visit, photographs of participant's skin cancer will be taken, and participants will undergo PDT treatment. The study team will also take photos on the day of Mohs surgery or ED\&C. There will be up to two blood draws for research. If participants do not want to come in for a PDT treatment prior to their Mohs surgery or ED\&C, they will have the option to participate by only allowing the study team to collect data about their skin cancer and their tissue from Mohs surgery or ED\&C.

This is a pilot clinical trial determining the effect of a Methionine-reduced diet on serum levels in subjects with solid tumors. These are subjects who will receive systemic standard of care cancer therapy.

To assess the feasibility and provide information on the utility of noninvasive line field confocal optical coherence tomography (LC-OCT) for the presurgical assessment of Mohs micrographic surgery sites in patients undergoing removal of cutaneous basal cell carcinomas (BCC).

This phase II trial studies whether providing cancer treatment in the home is preferred over the traditional clinic setting and if it improves treatment satisfaction in cancer patients living in the Florida Panhandle and surrounding areas. Typically, drug-related cancer care is provided at a medical center which causes patients to have to spend considerable time away from their family, friends, and familiar surroundings. This may add to the physical, emotional, social, and financial burden for patients and their families during this difficult time in their lives. The Cancer Connected Access and Remote Expertise (CARE) Beyond Walls (CCBW) program uses a specialized care team trained to provide cancer treatment in the patient's home setting. It is designed to support remote connection between the home health team and providers and Mayo clinic. This may be preferred over the traditional clinic setting which may improve treatment satisfaction in cancer patients living in the Florida Panhandle and surrounding areas.

This is an intent-to-treat, parallel design, multicenter randomized trial and the primary intervention is a double-blind comparison of Imiquimod (IMQ) vs. placebo cream for preventing basal cell carcinoma (BCC) of the skin on the face at one year and over 3 years after therapy. Participants will apply the IMQ or placebo cream to the face daily at bedtime for 12 weeks. This study will recruit 1630 Veterans at high risk of BCC from 17 VA medical centers.

Basal cell carcinoma (BCC) is the most frequent skin cancer in humans, primarily located in sun-exposed areas. The incidence of BCC increases with cumulative exposure to ultraviolet (UV) radiation and is particularly high in the elderly population, with a reported peak around 80 years of age. The new EADO classification distinguishes BCCs as 'easy-to-treat' and 'difficult-to-treat', subdivided into stages I-IV, with the aim of guiding therapeutic choices. However, in clinical practice, there is marked variability among specialists in classification and treatment selection, with potential implications for clinical outcomes. This study aims to investigate inter-operator variability in both classification and therapeutic decisions for BCC. Specifically, it analyzes how specialists from different disciplines-dermatologists, oncologists, plastic surgeons, maxillofacial surgeons, and radiation therapists-and with varying clinical experience in BCC management approach the same clinical cases.

The goal of this observational study is to find out if Raman Spectroscopy, a type of imaging, can be used to determine the size of skin cancer tumors. The main question it aims to answer is: -Can Raman Spectroscopy help figure out how far a tumor spreads? This study will take measurements using laser light from an experimental, handheld probe by lightly touching the skin.

This is a phase 2 trial assessing the efficacy of nivolumab, alone or in combination with relatlimab or ipilimumab in treating patients with locally-advanced unresectable or metastatic basal cell carcinoma.

Basal cell carcinoma (BCC) is the most common malignant skin tumour. The standard treatment is micrographically controlled surgery (MMS), which achieves high cure rates but requires considerable time and personnel. A key problem is the inadequate preoperative determination of tumour margins, which often leads to multiple cycles of excision. The aim of this multicentre, prospective, randomised controlled intervention study is to evaluate line-field confocal optical coherence tomography (LC-OCT) for preoperative margin determination in BCC within the framework of MMS. Research question: Can preoperative LC-OCT-assisted margin marking increase the efficiency of MMS by reducing the number of excision cycles required without compromising oncological safety? Methodology: Approximately 290 patients with histologically confirmed BCC will be enrolled at five German centres and randomly assigned to either standard MMS or MMS with upstream LC-OCT margin determination. In the intervention group, the excision margin will be specifically extended if a tumour is detected in the LC-OCT. Primary endpoint: Number of MMS cycles required to achieve R0 resection. Secondary endpoints: Total duration of surgery, size of surgical defect, cosmetic outcome (POSAS), patient satisfaction and stress, sensitivity and specificity of LC-OCT compared to histopathology. Significance: The study addresses the clinical conflict of objectives between complete tumour removal and maximum tissue preservation. Successful implementation could optimise MMS through modern imaging, conserve surgical resources and improve patient care in the long term.

This is a Phase 2 clinical trial with a 2:1 randomization comparing neoadjuvant Nivolumab + Relatlimab (Opdualag) vs neoadjuvant Nivolumab in patients with resectable high risk basal cell carcinoma (HR BCC)

Participants of this study will have a diagnosis of a solid tumor cancer that has come back to its original location or spread beyond its original location (advanced), came back (relapsed) or worsened (refractory) after standard treatments, or no standard treatments are available for the participants' cancer. The purpose of this study if to find the highest dose of MQ710 that causes few or mild side effects in participants with a solid tumor cancer diagnosis.

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.

This is a non-interventional study to prospectively test a suite of predictive biomarker models of immunotherapy resistance in patients with melanoma, non-melanoma skin cancers and other solid tumours. The study will evaluate the documentation, processes, accuracy and utility of the predictive biomarker model in clinical practice.

The aim is to use AI to assist surgeons in analyzing CLSM tissue slide images obtained during BCC surgeries with the aim to integrate it in real time. We plan to use AI to analyze CLSM images of BCCs and distinguish between tumor tissue, inflammatory tissue, and non-tumor/non-inflammatory tissue. This approach would provide surgeons with real-time feedback and automated image analysis, leading to a more targeted and efficient approach to tissue analysis. By improving the accuracy and speed of tissue analysis, our proposal could ultimately improve operative patient outcomes and benefit healthcare professionals.

This is a Phase 1/2, multi-center, open-label, dose-escalation and expansion study to evaluate safety and tolerability, PK, pharmacodynamic, and early signal of anti-tumor activity of MDNA11 alone or in combination with a checkpoint inhibitor in patients with advanced solid tumors.

The SAHARA trial assesses wether combining ultrahypofractionated accelerated radiotherapy (RT) with hyperthermia is as effective as standard hypofractionated high-dose radiation in treating non-melanoma skin cancer (NMSC).

Retrospective and Prospective Observational Study in Patients With Advanced Basal Cell Carcinoma.

Immunotherapy (IO), such as treatment with anti-PD-1, PD-L1, or CTLA-4 inhibitors, is a rapidly expanding treatment for multiple metastatic cancers with improved survival for certain cancers. However, the optimal duration of immunotherapies is currently unknown. Our hypothesis is that a reduced dose intensity of IO could be as effective as the current standard treatment in term of prevention of the disease progression. If proved right, this study will have a positive medico-economic impact by reduction of the costs associated with the treatment and the toxicity, and an increase of the patients' quality of life.

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.

The goal of this clinical trial is to compare the use of two photon fluorescence microscopy for detecting residual basal cell carcinoma during standard local excision.

This current registry study will analyze real-world data to address questions about disease characteristics and treatment patterns in NMSC patients based on the European NMSC-Registry. The overall objective is to describe characteristics, management and treatment outcomes for patients presenting with advanced NMSC (cSCC/BCC) or HR-cSCC in routine clinical practice, independent of treatments used across different European regions.

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.

The goal of this clinical trial is to evaluate the efficacy of using SP-002 in participants with locally advanced Basal cell carcinoma. The main question it aims to answer is what the objective response rate for a basal cell carcinoma tumor is following 1 or 3 cycles of SP-002 treatment given as an add-on to hedgehog pathway inhibitor therapy. Researchers will compare the objective response rate for treated Basal cell carcinoma tumors between 3 treatment Arms. * Arm 1 participants will receive daily hedgehog pathway inhibitor, and 3 cycles of SP-002 treatment. * Arm 2 participants will receive daily hedgehog pathway inhibitor, and 1 cycle of SP-002 treatment. * Arm 3 participants will receive daily hedgehog pathway inhibitor only.
