Filter by:Basal cell carcinoma (BCC) is the most common malignant skin lesion in white adults. It is a slow-growing tumour which despite low metastatic potential may cause significant local tissue destruction and patient morbidity. Methyl aminolevulinate cream plus photodynamic therapy (MAL-PDT) for BCC is currently approved for a procedure using 2 treatment sessions 1 week apart. This procedure is considered quite time- and resource-consuming. Introducing a single treatment session, with a new PDT session for treatment failures after 3 months, might represent an attractive simplification. This randomised controlled single-blinded multi-centre study primarily aims to compare BCC lesion response rate of two treatment schedules: (a) 1 single treatment of Metvix-PDT with re-treatment of non-complete responders by 3 months, and (b) the usual schedule of 2 standard Metvix(R) PDT treatments 1 week apart. Secondary objectives are to investigate the treatment response in relation to clinical and histological tumour characteristics such as tumour thickness, subtype and immunohistochemical markers.
Human Basal Cell Carcinomas (BCCs) can be ablated by treating them with nanosecond pulsed electric fields (nsPEF)
The investigators aim to test the hypothesis and to proof thank to laser speckle contrast imaging that post-occlusive reactive hyperemia (PORH) can be induced through a tumor, in this case, through a basal cell carcinoma, which will be used as a model of study of tumor vasculature. This new concept of tumor perfusion artificial increase could be used in the future for malignant tumors treatment, in order to increase tumor mean oxygen partial pressure (thus decreasing tumor hypoxia, hallmark of malignant tumors) during cancerology therapies, like radiotherapy and/or chemotherapy, and increase their efficacy. This clinical trial will use skin flap model for trunk and facial basal cell carcinoma (BCC), with respect the classical excision margin of BCC surgery (3-4mm): after local anesthesia, a little random pattern skin flap will be raised around the BCC, then the cutaneous pedicle will be clamped with surgical clamp for 3 minutes and clamp released. In case of limb BCC, limb tourniquet will be used, and occluded during 3 minutes upstream to the BCC location. During all steps of experimentation, laser speckle imaging will be used to measure continuously the peri-tumoral and tumoral perfusion, start from tumor excision, up to10 minutes after tumor pedicle clamp or tourniquet release.
Basal Cell Carcinoma (BCC) is the most common malignant growth in the world. Treatment is primarily surgical with the goal of excising the growth in its entirety. When pathology results show that this has not been achieved, a re-excision is routinely performed. This study examines retrospectively the percentage of re-excisions of BCC that actually proved to be positive (exhibited growth) among those re-excisions performed at Rambam Healthcare Campus and Zvulun Community Medical Center during the years 2008-10.
Skin cancer is the most common cancer in Caucasians. Basal cell carcinoma (BCC) is the most frequent skin cancer with around 44.000 new tumours per year in the Netherlands, and its incidence is still rising. Prior to treatment, a punch biopsy (PB) is taken from the suspected lesion, in order to determine the subtype of BCC. There are three different histological subtypes of BCC, from least to most aggressive: superficial, nodular and aggressive. Based on the most aggressive subtype seen in the PB, a suitable surgical margin is chosen. Surgical excision (SE) is the treatment of first choice in all BCC subtypes according to the Dutch guidelines. Recent developments of non-invasive therapies for superficial BCC might be the first choice of treatment in the future. These non-invasive treatments (photodynamic therapy (PDT), Imiquimod and 5-fluorouracil (5-FU)) have better cosmetic results than SE and are therefore also used in the Maastricht University Medical Center. Drawback is a higher recurrence rate than SE. As nodular and aggressive subtypes grow deeper into the dermis, they have to be treated with SE with a 3 mm and 5 mm margin respectively. If BCC are located in the H-zone, the treatment will be Mohs micrographic surgery (MMS). Unfortunately, 30% of subtypes seen in the PB do not correspond with the subtype seen in the subsequent SE/MMS. The consequence is overtreatment and undertreatment. A potential better or equal way to determine the BCC subtype might be the clinical diagnosis. To our knowledge, there is no literature about the diagnostic value of the clinical diagnosis to determine the subtype of BCC seen in the SE/MMS specimen. We want to confirm the hypothesis that the clinical diagnosis is as good as, or even better than the histological diagnosis by PB to determine the BCC subtype in the subsequent SE/MMS. In this case, patients don't have to undergo an extra procedure, diagnostic route is shortened. - Primary objective: to establish the observed agreement of clinical diagnosis compared to histological diagnosis by to determine the most aggressive subtype of BCC - Secondary objectives: inter-observer and intra-observer variability of dermatologists and pathologists to determine subtype BCC.
This single-arm, open-label, multi-center study will evaluate the safety and efficacy of vismodegib (GDC-0449) in patients with locally advanced or metastatic basal cell carcinoma. Patients will receive oral doses of vismodegib 150 mg once daily until disease progression or unacceptable toxicity.
Basal cell carcinoma (BCC) is the most frequent malignant tumor in Caucasians and the incidence is still increasing with 3-8% each year. Since BCCs generally occur on sun-exposed areas of the skin, the rice in incidence is mainly explained by the increasing exposure to (intermittent) ultraviolet radiation. Surgical excision is still the standard treatment for (micro)nodular BCCs. The costs as well as the increased workload are stressing the health care system even further and posing BCC an important health care problem. Since half of the BCCs arise primarily on the face & (bald) head and treatment by surgical excision may result in disfiguring scars, patients often experience a dramatic decrease of their quality of life. Hence, there is an urgent medical and societal need for a simple and cheap (targeted) treatment, preferably to be performed by the patients themselves. This treatment must be safe and effective. Such treatment is not available yet. BCC tumorigenesis is complex and must be multifactorial. Genetic alterations of multiple components of the Sonic Hedgehog (SHH) pathway are involved in sporadic BCC pathogenesis; inactivating mutations in Patched-1 (PTCH1) and activating mutations of Smoothened (SMO) and Suppressor of Fused (SU(FU)). With this knowledge, inhibition of the SHH pathway by SMO antagonists was successfully administered, however treatment resulted only in partial clinical response ofBCC. Recently, involvement of the Wingless (Wnt) pathway has been proven to be essential in BCC tumorigenic response. Moreover, a recent study of our own department provides the first evidence that epigenetic alterations, particularly promoter hypermethylation, influence both the SHH and Wnt pathway (own data, not published), which can serve as therapeutic targets. Both non-steroidal anti-inflammatory drugs (NSAlDS) and vitamin D derivatives are able to directly or indirectly target the Wnt pathway. Furthermore, vitamin D3 is able to inhibit Smoothened (SMO) in vitro, resulting in inhibition of the SHH pathway. Although in vivo studies are lacking, the investigators assume that topical application of these drugs may inhibit BCC growth and/or may cure BCC and thus might provide very promising future perspectives. Calcitriol and NSAlDs ointments are both already available for other indications and save in use. Eventually, our approach may result in a systematic approach to BCC, targeting (epi)genetic changes to treat and/or prevent further tumour growth.
This was a phase II, double-blind, randomized, proof-of-concept, dose-ranging trial evaluating the efficacy, safety and pharmacokinetics of oral LDE225 in treatment of adult patients with NBCCS. This was an exploratory study designed to demonstrate preliminary efficacy of LDE225 in this indication. This study included a Screening period of approximately 4 weeks, treatment period duration of 12 weeks with initial follow-up of approximately 6-8 weeks followed by a long-term follow-up period.
This study assessed the efficacy and safety of oral treatment with two dose levels of LDE225 in patients with locally advanced or metastatic BCC.
This study is primarily designed to investigate whether treatment, once daily for up to three consecutive days, with PEP005 (ingenol mebutate) Gel, 0.05% will be safe and tolerable in patients with superficial Basal Cell Carcinoma (sBCC) lesions on the trunk and extremities.
