Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (BIOMARKERS, TUMOR) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm.

Epithelial cells lining the SKIN; the MOUTH; the NOSE; and the ANAL CANAL derive from ectoderm; those lining the RESPIRATORY SYSTEM and the DIGESTIVE SYSTEM derive from endoderm; others (CARDIOVASCULAR SYSTEM and LYMPHATIC SYSTEM) derive from mesoderm. Epithelial cells can be classified mainly by cell shape and function into squamous, glandular and transitional epithelial cells.
RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.

The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

A malignant neoplasm derived from cells that are capable of forming melanin, which may occur in the skin of any part of the body, in the eye, or, rarely, in the mucous membranes of the genitalia, anus, oral cavity, or other sites. It occurs mostly in adults and may originate de novo or from a pigmented nevus or malignant lentigo. Melanomas frequently metastasize widely, and the regional lymph nodes, liver, lungs, and brain are likely to be involved. The incidence of malignant skin melanomas is rising rapidly in all parts of the world. (Stedman, 25th ed; from Rook et al., Textbook of Dermatology, 4th ed, p2445)

PTCH2, a novel human patched gene, undergoing alternative splicing and up-regulated in basal cell carcinomas. (1/1029)

By a combination of cDNA library screening, rapid amplification of cDNA ends analysis, and BAC sequencing, a novel human patched-like gene (PTCH2) has been cloned and sequenced. The genomic organization is similar to PTCH1 with 22 exons and, by radiation hybrid mapping, PTCH2 has been localized to chromosome 1p33-34, a region often lost in a variety of tumors. Several alternatively spliced mRNA forms of PTCH2 were identified, including transcripts lacking segments thought to be involved in sonic hedgehog binding and mRNAs with differentially defined 3' terminal exons. In situ hybridization revealed high expression of PTCH2 transcripts in both familial and sporadic basal cell carcinomas in similarity to what has been observed for PTCH1, suggesting a negative regulation of PTCH2 by PTCH1. This finding tightly links PTCH2 with the sonic hedgehog/PTCH signaling pathway, implying that PTCH2 has related, but yet distinct, functions than PTCH1.  (+info)

Optimum porphyrin accumulation in epithelial skin tumours and psoriatic lesions after topical application of delta-aminolaevulinic acid. (2/1029)

Photodynamic therapy with topically applied delta-aminolaevulinic acid is used to treat skin tumours by employing endogenously formed porphyrins as photosensitizers. This study examines the time course of porphyrin metabolite formation after topical application of delta-aminolaevulinic acid. Porphyrin biosynthesis in human skin tumours (basal cell carcinoma, squamous cell carcinoma), in psoriatic lesions, and in normal skin was investigated. Skin areas were treated with delta-aminolaevulinic acid, and levels of total porphyrins, porphyrin metabolites and proteins were measured in samples excised after 1, 2, 4, 6, 9, 12 and 24 h. There was an increase in porphyrin biosynthesis in all tissues with maximum porphyrin levels in tumours between 2 and 6 h and in psoriatic lesions 6 h after treatment. The pattern of porphyrins showed no significant difference between normal and neoplastic skin, protoporphyrin being the predominant metabolite. The results suggest that optimum irradiation time for superficial epithelial skin tumours may be as soon as 2 h after application of delta-aminolaevulinic acid, whereas for treatment of psoriatic lesions an application time of 6 h is more suitable.  (+info)

A man with a prosthetic ear and multiple pulmonary nodules. (3/1029)

Basal cell carcinoma is generally regarded as a relatively indolent tumor easily controlled with local therapy. When neglected or inadequately treated this tumor can become locally aggressive and in rare circumstances metastasize. This report documents a case of basal cell carcinoma metastatic to the lung that resulted in rapidly progressive respiratory failure and death.  (+info)

Color Doppler sonography of focal lesions of the skin and subcutaneous tissue. (4/1029)

We evaluated with color Doppler sonography 71 visible and palpable nodules of the skin and subcutaneous tissue from 51 patients. The nodules were classified as avascular (type I), hypovascular with a single vascular pole (type II), hypervascular with multiple peripheral poles (type III), and hypervascular with internal vessels (type IV). Of the 32 malignant nodules, 9% showed a type I pattern, 50% had a type III pattern, and 41% had a type IV pattern; of the 39 benign nodules, 86% showed a type I pattern and 14% had a type II pattern. The sensitivity and specificity of hypervascularity in malignant lesions were 90% and 100%, respectively, whereas the sensitivity and specificity of hypovascularity in benign lesions were 100% and 90%, respectively. The authors conclude that color Doppler sonography is able to increase the specificity of ultrasonography in the evaluation of nodular lesions of the skin.  (+info)

Long-term results after surgical basal cell carcinoma excision in the eyelid region. (5/1029)

AIMS: To evaluate the data for patients with basal cell carcinoma (BCC) in the eyelid region, to demonstrate histologically controlled tumour excision, and to prove the efficacy of the treatment on the basis of long term observations. METHODS: Retrospective analysis of 382 microscopically controlled BCC excisions in the eyelid apparatus (350 patients) in a follow up study over 5.7 (SD 1.1) years. Tumour location, tumour size, and histological results were recorded. The same procedure was followed for recurrences. Follow up examinations were carried out 1, 3, 6, and 12 months after the operation, and then annually for a further 4 years or longer. RESULTS: A recurrence rate of 5.36% was observed after the primary operation. 60.3% of first recurrences occurred in the medial canthus, 41.2% showed in depth extension, and sclerosing types were overly represented at 35.3%. After the second operation the recurrence rate increased to 14.7% and reached 50% after a third and fourth operation. CONCLUSIONS: The greatest risk of recurrence exists for BCCs of the medial canthus with in depth extension, and for sclerosing types. The recurrence rate increases after every operation. For high risk cases, consideration should be given to adjuvant treatment such as radiotherapy.  (+info)

The sebaceous nevus: a nevus with deletions of the PTCH gene. (6/1029)

Sebaceous nevi (SN) are congenital malformations of the skin with the potential to develop into basal cell carcinoma (BCC). To date, the molecular basis for their carcinogenic potential remains unknown. The genetic defect in BCC is known and involves the human homologue of Drosophila patched (PTCH) on chromosome 9q22.3. The objective of this study was to test whether allelic deletion of the PTCH gene could already be detected in SN. Twenty-one paraffin-embedded SN were investigated in this study. Basaloid cells in conjunction with mature sebaceous glands as well as epidermal layer apart from SN were microdissected and subjected to single-step DNA extraction. We performed the analysis with polymorphic markers at 9q22.3 (D9S15, D9S252, D9S287, and D9S303). Of the 20 informative SN, 8 (40%) exhibited loss of heterozygosity at least at one locus. Here, we provide the first evidence of the involvement of the tumor suppressor gene PTCH in SN. Whether PTCH deletion in SN is associated with progression to BCC and/or other appendageal tumors should be addressed in future studies.  (+info)

High levels of patched gene mutations in basal-cell carcinomas from patients with xeroderma pigmentosum. (7/1029)

Recently, hptc, a human gene homologous to the Drosophila segment polarity gene patched (ptc), has been implicated in the nevoid basal-cell carcinoma (BCC) syndrome, and somatic mutations of hptc also have been found in sporadic BCCs, the most frequent cancers found in the white population. We have analyzed the hptc gene, postulated to be a tumor suppressor gene, in 22 BCCs from patients with the hyperphotosensitive genodermatosis xeroderma pigmentosum (XP). Patients with XP are deficient in the repair of UV-induced DNA lesions and are characterized by their predisposition to cancers in sun-exposed skin. Analysis using PCR-single-strand conformation polymorphism of the hptc gene identified 19 alterations in 16 of 22 (73%) of the BCCs examined. Only two (11%) deletions of the hptc gene were found in XP BCCs compared with >30% rearrangement observed in non-XP sporadic BCCs, and 17 of 19 (89%) were base substitutions. Among the 17 base substitutions, 11 (65%) were CC --> TT tandem mutations, and 4 (23%) were C --> T substitutions, all targeted at bipyrimidine sites. Hence, a significantly higher number (15 of 19; 79%) of UV-specific alterations are seen in XP tumors, in contrast to non-XP sporadic BCCs. Interestingly, we have found that in 7 of 14 (50%) XP BCCs analyzed, both hptc and the tumor suppressor gene p53 are mutated. Not only have our data indicated the key role played by hptc in the development of BCCs, they also have substantiated the link between unrepaired UV-induced DNA lesions and skin carcinogenesis, as exemplified by the UV-specific alterations of different genes in the same tumors.  (+info)

Mutational spectrum of p53 gene in arsenic-related skin cancers from the blackfoot disease endemic area of Taiwan. (8/1029)

To understand the role of p53 tumour suppressor gene in the carcinogenesis of arsenic-related skin cancers from the blackfoot disease endemic area of Taiwan, we collected tumour samples from 23 patients with Bowen's disease, seven patients with basal cell carcinomas (BCC) and nine patients with squamous cell carcinomas (SCC). The result showed that p53 gene mutations were found in 39% of cases with Bowen's disease (9/23), 28.6% of cases with BCC (2/7) and 55.6% of cases with SCC (5/9). Most of the mutation sites were located on exon 5 and exon 8. Moreover, the results from direct sequencing indicated that missense mutations were found at codon 149 (C-->T) in one case, codon 175 (G-->A) in three cases, codon 273 (G-->C) in three cases, codon 292 (T-->A) in one case, codon 283 (G-->T) in one case, codon 172 (T-->C) in one case and codon 284 (C-->A) in one case. In addition, silent mutations were also found in four cases. These mutations were located at codons 174, 253, 289 and 298 respectively. In immunohistochemistry analysis, p53 overexpression was found in 43.5% (10/23) of cases with Bowen's disease, 14% (1/7) of cases with BCC and 44% (4/9) of cases with SSC. These findings showed that p53 gene mutation rate in arsenic-related skin cancers from the blackfoot disease endemic area of Taiwan is high and that the mutation types are different from those in UV-induced skin cancers.  (+info)

Basal cell carcinoma is a slow growing non-melanoma skin cancer. It is thought to be caused by over exposure to the harmful ultraviolet (UV) rays of the sun. It can be highly disfiguring if allowed to grow, but almost never spreads beyond the original tumor site. Only in rare cases can basal cell carcinoma spread to other parts of the body and become life-threatening. This disease should be treated promptly due to its ability to destroy tissue in the areas that it infiltrates.. What do basal cell carcinomas look like?. Basal cell carcinomas are abnormal, uncontrolled growths or lesions that arise in the skins basal cells, which line the deepest layer of the outermost layer of the skin, known as the epidermis. Basal cell carcinomas often look like open sores, red patches, pink growths, shiny bumps, or scars.. What are the consequences of basal cell carcinomas?.

BACKGROUND: Cutaneous basal cell carcinoma (BCC) is the commonest cancer worldwide. BCC is locally invasive and the surrounding stromal microenvironment is pivotal for tumourigenesis. Cancer associated fibroblasts (CAFs) in the microenvironment are essential for tumour growth in a variety of neoplasms but their role in BCC is poorly understood.. METHODS: Material included facial BCC and control skin from the peritumoural area and from the buttocks. With next-generation sequencing (NGS) we compared mRNA expression between BCC and peritumoural skin. qRT-PCR, immunohistochemical and immunofluorescent staining were performed to validate the NGS results and to investigate CAF-related cyto-and chemokines.. RESULTS: NGS revealed upregulation of 65 genes in BCC coding for extracellular matrix components pointing at CAF-related matrix remodeling. qRT-PCR showed increased mRNA expression of CAF markers FAP-α, PDGFR-β and prolyl-4-hydroxylase in BCC. Peritumoural skin (but not buttock skin) also ...
The aim of this study was to evaluate the effect of photodynamic therapy with topical methylaminolevulinate for the treatment of basal cell carcinomas in a single dermatological department. Ninety patients (34.4% men and 65.6% women) with a total of 157 basal cell carcinomas (111 superficial, 40 nodular, 6 unknown) were treated. Primary endpoint was clinically observed recurrence verified by biopsy 3, 6 and 12 months after treatment, then once a year. Estimated patient recurrence rates were 7% at 3 months, 19% at 6 months, 27% at 12 months and 31% at 24 months. Patients aged over 60 years had significantly higher estimated recurrence rates compared with patients aged 60 years or under (at 12 months, 35% vs. 19%, p = 0.01). Estimated recurrence rates for tumours was 4% at 3 months, 11% at 6 months, 16% at 12 months and 19% at 24 months. There were significantly higher estimated recurrence rates for nodular basal cell carcinomas compared with superficial basal cell carcinomas (at 12 months, 28% ...
Melanoma gets the headlines, and for good reason, with a mortality rate at around 10% it is far higher than all other forms of skin cancer, sitting at less than 1% overall.. However, this focus on mortality rates has made people think that only melanoma is serious and that other forms of skin cancer are nothing to worry about.. So, you might be surprised to hear that as many Australians die from non-melanoma skin cancers each year as they do from melanoma.. What are non-melanoma skin cancers? Non-melanoma skin cancer includes basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Typically, BCC account for 70% and SCC for 29%, with rare forms of non-melanoma skin cancers making up the remaining 1%.. PWC predicts that around 1,700 Australians will die from non-melanoma skin cancer in 2020 (this compares to 1,400-2,000 melanoma related deaths in Australia per annum). Sadly, that translates to around 4 people dying each day in Australia due to non-melanoma skin cancer. You might be ...
Objectives: To evaluate the safety of two applications of PEP005 (ingenol mebutate) gel in superficial basal cell carcinoma. Efficacy was a secondary end-point. Methods: Randomized, vehicle-controlled, phase IIa study conducted at eight private dermatology clinics in Australia. A total of 60 patients with histologically confirmed superficial basal cell carcinoma (lesion size, 4-15 mm) were randomized to treatment on days 1 and 2 (Arm A) or days 1 and 8 (Arm B) and, within each arm, to ingenol mebutate gel, 0.0025%, 0.01% or 0.05%, or vehicle gel. The main outcome measures were the incidence and severity of adverse events and local skin responses in Arms A and B; lesion clearance at day 85 was a secondary measure. Results: The incidence of adverse events was low. One patient treated with ingenol mebutate gel, 0.05% in Arm A experienced severe flaking/scaling/dryness extending beyond the application site. Non-severe, potentially treatment-related events included erythema extending beyond the application
Author(s): Xu, Ann; Patel, Viraat; Sutton, Leigh; Orengo, Ida | Abstract: The diagnosis of infiltrative basal cell carcinoma (BCC) can be delayed owing to its often subtle clinical findings. A 90-year-old woman presented with an asymptomatic annular pink plaque on her left shin that was clinically diagnosed as tinea corporis. After years of not responding to topical anti-fungal therapy, biopsies confirmed a diagnosis of infiltrative BCC. We discuss the differential diagnosis of the case, the difficulties in identifying infiltrative BCC, and the pathologic features of infiltrative BCC.

There are various forms of basal cell carcinoma.. Nodular basal cell carcinomas present as elevated lumps in the skin with a shiny surface, which often develop a small sore at the centre. Other, more superficial basal cell carcinomas appear as thin, brown or red patches of skin. They can easily be mistaken for dry skin patches, actinic keratosis, eczema or psoriasis, but they do not respond to moisturising creams or topical steroids. Patients typically notice that they have a sore that wont heal.. ...

Frequent localization of the disease are exposed skin - face and scalp area of the head. Only in 20% of cases the tumor appears in closed clothing areas (trunk, limbs). Basal cell carcinoma of skin, usually occurs in older people, but in recent years the disease is diagnosed in younger people. Experts explain this growing popularity of travel to tropical countries and the Vogue for tanning. What is basal cell carcinoma Basal cell skin cancer is common among Europeans kind of a malignant tumor. Basal cell carcinoma occurs in the cells of the skin layer, which is responsible for the regeneration of the epithelium or at the base of hair follicles. Despite the fact that the disease is considered as malignant type of tumor, it practically never leads to the development of distant metastases. The tumor tend to increase invasive manner, it spreads into the surrounding tissues and destroys them. Starts as skin cancer?

In 2012 alone, it was estimated that over 5 million cases of non-melanoma skin cancer, including both basal cell carcinoma and squamous cell carcinoma, were treated in at least 3 million Americans.. Skin cancer is on the rise as well. Between 1976 and 2010, incidences of basal cell carcinoma increased by 145%. Squamous cell carcinoma increased by over 260% in the same time period.. The Latest Treatment Option for Non-Melanoma Skin Cancers. To combat this large increase in the incidence of non-melanoma skin cancers, Sensus Healthcare developed the SRT-100™, a system that uses precise, calibrated doses of Superficial Radiation Therapy to destroy cancer cell DNA, effectively disrupting their ...
Basal cell carcinoma (BCC) is the most common cancer among skin cancers. The incidence of cutaneous malignant melanoma (CMM) and non-melanoma skin cancer (NMSC) has increased more than 600% worldwide since the 1940s. Carcinogenesis is a multi-step process involving multiple genetic alterations. The connection between cell cycle proliferation and cancer resulting in deregulated cellular proliferation leads to cancer. Cancer has been associated with disturbances in cell cycle regulation. Recent studies have shown that p16, CDK6 and CCND1 mRNA genes and protein expression are involved in the tumorgenesis of skin cancer. These genes play a role in cell cycle proliferation. In this study, we assessed the expression of a cyclin, a cyclin dependent kinase, and a cyclin kinase inhibitor in skin BCC tissue. Reverse Transcription in situ polymerase chain reaction (RT in situ PCR) and immunohistochemistry (IHC) were used to detect the expression of p16, CDK6 and CCND1 mRNA genes through them of protein ...
Basal cell carcinomas in elderly patients treated by cryotherapy Anca Chiriac,1 Doina Mihaila,2 Liliana Foia,3, Caius Solovan4 1Department of Dermatology, Nicolina Medical Center, 2Department of Pathology, St Maria Children's Hospital, 3Surgical Department, Grigore T Popa University of Medicine and Pharmacy, Iaşi, Romania; 4Victor Babe University of Medicine, Timişoara, Romania Abstract: Basal cell carcinoma is a malignant skin tumor with high incidence in our country, especially in rural areas, on sun-exposed skin (particularly on the face) in elderly patients. We present three cases of basal cell carcinoma with good results with cryotherapy. This report aims to outline and to prove that in some difficult situations, a simple, inexpensive, easy-to-perform procedure with no contraindications and with minimal side effects (erythema, mild pain) can be applied and resolve such cases.

Epidemiologic studies suggest that exposure to sunlight is the primary etiologic agent for basal cell carcinoma. Formation of UV-induced DNA damage is believed to be a crucial event in the process leading to skin cancer. In this study, repair of photoproducts in DNA was followed in the skin of patients with basal cell carcinoma and control subjects. The subjects were exposed to 800 J/m(2) Commission Internationale de 1Eclairag of solar-simulating radiation on buttock skin. Biopsies were taken at 0 hour, 24 hours, and 3 weeks after the exposure. Two cyclobutane pyrimidine dimers, TT=C and TT=T, were measured using a sensitive (32)P-postlabeling assay. Initial levels of both TT=C and TT=T differed between individuals in both groups. The levels of TT=T in patients with basal cell carcinoma and controls were similar (9.9 +/- 4.0 and 9.2 +/- 2.9 products per 10(6) normal nucleotides), whereas the level of TT=C was significantly lower in controls than in patients with basal cell carcinoma (6.2 +/- ...

Press Release issued Feb 10, 2015: Non-melanoma skin cancers develop in the outermost layer of skin, known as epidermis. It is caused by increased exposure of genetic mutations, UV rays and ozone layer depletion. Non-melanoma skin cancer is mainly classified into two types. They are basal cell carcinoma and squamous cell carcinoma. Basal cell carcinoma is one of the most common types of skin cancers. It accounts about 70% of all skin cancers. Basal cell carcinoma starts underneath of the epidermis. Basal cell carcinoma usually appears as a red or pink lump. It usually develops on ears, face and neck. Squamous cell carcinoma accounts 20% of skin cancer. It starts on the upper side of epidermis. Squamous cell carcinoma appears as a red lump which develops into tumors. This type of cancer usually appears on that parts of the body which are directly exposed to the sun. It includes hands, face, ears, lips and legs.
Smoothened (SMO) inhibitors are under clinical investigation for the treatment of several cancers. Vismodegib is approved for the treatment of locally advanced and metastatic basal cell carcinoma (BCC). Most BCC patients experience significant clinical benefit on vismodegib, but some develop resistance. Genomic analysis of tumor biopsies revealed that vismodegib resistance is associated with Hedgehog (Hh) pathway reactivation, predominantly through mutation of the drug target SMO and to a lesser extent through concurrent copy number changes in SUFU and GLI2. SMO mutations either directly impaired drug binding or activated SMO to varying levels. Furthermore, we found evidence for intra-tumor heterogeneity, suggesting that a combination of therapies targeting components at multiple levels of the Hh pathway is required to overcome resistance. ...

Nonmelanoma skin cancer is the most common cancer worldwide (melanoma skin cancer is much more rare - though increasing at a very fast rate). Recent studies suggest that nonmelanoma skin cancer is becoming much more common among women, and the increase is especially dramatic among young women. According to the Canadian Dermatology Association, a person born in 1930 faces a 1-in-500 chance of developing nonmelanoma skin cancer in his or her lifetime, whereas a person born after 1994 faces a 1-in-7 chance.. This increase has occurred because more people are overexposed to ultraviolet (UV) radiation. People are living longer. People of this generation have often been exposed to the sun more than their parents because they tend to have more opportunity for leisure activities in the sun. The thinning of the earths ozone layer (caused by pollution and chemicals) also contributes to the increased occurrence of nonmelanoma skin cancer.. The two most common types of nonmelanoma skin cancer are basal ...
Skin cancer as a single entity is the most common malignancy in North America, accounting for half of all human cancers. It comprises two types: melanoma and nonmelanoma skin cancers. Of the nonmelanomas, basal cell carcinoma (BCC) constitutes about 80% of the cancers diagnosed every year. BCC usually occurs in sun-exposed areas such as the face and extremities. Occurrence in the nipple areolar complex is very rare. We present a case of a Caucasian woman who presented with what was initially thought to be invasive carcinoma of the breast involving the nipple areolar complex (NAC); however, the diagnosis was revealed to be a basal cell carcinoma after histopathological examination. The tumor was treated with modified radical mastectomy, with negative margins. The importance of this case lies in the rare site of presentation of basal cell carcinoma and the importance of early detection.
Basal Cell Carcinoma Approximately more than one million new basal cell carcinoma diagnosis are currently recognized each year in the United States, and the incidence is rising. Basal cell carcinoma usually appears on skin that has been exposed to the sun such as the face, ears, chest, back, legs, and scalp. The appearance of BCC is that of a pink, slightly elevated growth, a reddish patch of skin, a raised, shiny, skin-colored bump with tiny blood vessels, or a sore that continuously heals and then re-opens. BCC grows slowly and usually does not metastasize. It occurs more often in fair-skinned individuals. In the past, BCC usually appeared in older individuals, but has been appearing more in younger people because of sun exposure at an earlier age.. Moles and Melanoma. Squamous Cell Carcinoma.

The human homologue of the Drosophila segment polarity gene patched (PTCH) has recently been identified as the tumor suppressor gene responsible for the nevoid basal cell carcinoma (BCC) syndrome (H. Hahn et al., Cell, 85: 841-851, 1996; R. L. Johnson et al., Science (Washington DC), 272: 1668-1671, 1996). In addition to multiple BCCs, patients with nevoid BCC syndrome have a predisposition for the development of primitive neuroectodermal tumors (PNETs) of the central nervous system. We have analyzed 9 sporadic BCCs and 37 PNETs for mutation and expression of the PTCH gene. PTCH mutations were found in 3 BCCs (33.3%) and in 5 PNETs (14%), including 1 of 5 cerebral PNETs, 2 of 15 medulloblastomas, and 2 of 17 desmoplastic medulloblastomas. The sequence changes in six of these tumors (four PNETs, two BCCs) were mutations predicted to result in truncated proteins. Missense mutations were detected in one PNET and one BCC each. In addition, novel sequence polymorphisms were found in exon 2, intron 5, ...

CYLD is a deubiquitination enzyme that regulates different cellular processes, such as cell proliferation and cell survival. Mutation and loss of heterozygosity of the CYLD gene causes development of cylindromatosis, a benign tumour originating from the skin. Our study shows that CYLD expression is dramatically downregulated in basal cell carcinoma (BCC), the most common cancer in humans. Reduced CYLD expression in basal cell carcinoma was mediated by GLI1-dependent activation of the transcriptional repressor Snail. Inhibition of GLI1 restored the CYLD expression-mediated Snail signaling pathway, and caused a significant delay in the G1 to S phase transition, as well as proliferation. Our data suggest that GLI1-mediated suppression of CYLD has a significant role in basal cell carcinoma progression.

Basal cell nevus syndrome (BCNS; MIM 109400) also known as Gorlin syndrome, is an autosomal dominant disease characterized by basal cell tumors, palmar and plantar pits, jaw cysts and skeletal anomalies. Radiological findings include calcification of the falx cerebri, bridged sella, bifid ribs, hemivertebrae, and flame-shaped lucencies of the phalanges, metacarpal, and carpal bones of the hands. These patients can also have medulloblastoma, ovarian calcification or fibroma and cardiac fibroma. Craniofacial findings may include coarse facies, macrocephaly, hypertelorism, frontal bossing and cleft palate. BCNS can be caused by mutations in the PTCH1, PTCH2 or SUFU genes. These genes code for protein patched homolog 1, protein patched homolog 2 and suppressor of fused homolog.. The basal cell nevus syndrome NGS panel consists of three genes: PTCH1, PTCH2 and SUFU..

BACKGROUND The Hedgehog pathway inhibitor vismodegib has shown clinical benefit in patients with advanced basal cell carcinoma and is approved for treatment of patients with advanced basal cell carcinoma for whom surgery is inappropriate. STEVIE was designed to assess the safety of vismodegib in a situation similar to routine practice, with a long follow-up. METHODS In this multicentre, open-label trial, adult patients with histologically confirmed locally advanced basal cell carcinoma or metastatic basal cell carcinoma were recruited from regional referral centres or specialist clinics. Eligible patients were aged 18 years or older with an Eastern Cooperative Oncology Group (ECOG) performance status of 0-2, and adequate organ function. Patients with locally advanced basal cell carcinoma had to have been deemed ineligible for surgery. All patients received 150 mg oral vismodegib capsules once a day on a continuous basis in 28-day cycles. The primary objective was safety (incidence of adverse ...
Basal cell nevus syndrome is caused by changes in a tumor suppressor gene, called PTCH1, located on chromosome 9. Mutations in this gene may increase the risk of some cancers. Molecular genetic testing of PTCH1 is available on a clinical basis.. Tumor suppressor genes usually control cell growth and cell death. Every person is born with two copies of each tumor supressor gene, one inherited from his or her mother and one from his or her father. Both copies of a tumor suppressor gene must be altered, or mutated, before a person may develop cancer. With basal cell nevus syndrome, the first mutation is inherited from either the mother or the father in 70 to 80 percent of cases. In 20 to 30 percent of cases, the first mutation is not inherited and arises de novo (for the first time) in the affected person. Whether de novo or inherited, this first mutation is present in all of the cells of the body from conception and is called a germline mutation.. Whether a person who has a germline mutation will ...

Cancer of the skin is the most common cancer in Caucasians and basal cell carcinomas (BCC) account for 90% of all skin cancers. The vast majority of BCC cases are sporadic, though there is a rare familial syndrome basal cell nevus syndrome (BCNS, or Gorlin syndrome) that predisposes to development of BCC. In addition, there is strong epidemiological and genetic evidence that demonstrates UV exposure as a risk factor of prime importance. The development of basal cell carcinoma is associated with constitutive activation of sonic hedgehog signaling. The mutations in SMOH, PTCH1, and SHH in BCCs result in continuous activation of target genes. At a cellular level, sonic hedgehog signaling promotes cell proliferation. Mutations in TP53 are also found with high frequency (>50%) in sporadic BCC ...

Basal cell carcinoma is the most common skin cancer mainly caused by prolonged exposure to ultraviolet rays. It is also known as rodent ulcer or basal cell epithelioma. The main mechanism suggested is prolonged exposure to high intensity ultraviolet rays, which causes DNA damage. Pigmented basal cell carcinoma is a rare variety of basal cell carcinoma. Usually, it presents as pigmented nodular mass over the nose or malar region. Other differential diagnoses of this mass, are malignant melanoma and seborrheic keratosis. Treatment of choice is surgical excision with 2 mm of margins.

The nevoid basal cell carcinoma syndrome (NBCCS), or Gorlin syndrome, is a multisystem autosomal dominant disorder. The salient features of this syndrome include multiple basal cell carcinomas, palmar and/or plantar pits, odontogenic keratocysts, skeletal and developmental anomalies, and ectopic calcification. Other features include such tumors as ovarian fibromas and medulloblastomas. There is extensive interfamilial as well as intrafamilial variability with respect to the manifestation and severity of the phenotype. Alterations in the human homologue (PTCH) of the Drosophila segment polarity gene patched have been identified in NBCCS patients as well as tumors associated with this syndrome. We report several mutations in this gene in NBCCS patients and present the clinical phenotypes of the individuals in whom these mutations were identified.. ...

Skin cancer is often categorized as melanoma or non-melanoma. Melanoma is a cancer that begins in melanocytes. It is less common than non-melanoma skin cancer, but tends to be more aggressive. In 2006 an estimated 62,000 individuals in the U.S. will be diagnosed with melanoma, and close to 8,000 will die of the disease.1. The most common type of non-melanoma skin cancer is basal cell carcinoma. This type of cancer rarely spreads to distant sites in the body, but it can be disfiguring and may invade nearby tissues.. The second most common type of non-melanoma skin cancer is squamous cell carcinoma. Although this type of cancer is more likely to metastasize (spread to lymph nodes or other sites in the body) than basal cell carcinoma, metastasis is still rare. Both basal cell carcinoma and squamous cell carcinoma most commonly develop on sun-exposed parts of the skin, but can develop on other parts of the skin as well.. An alarming trend in both melanoma and non-melanoma skin cancers is that the ...

Among the group with metastatic basal cell cancer, overall response rate was 30%, and stable disease was observed in 63%. For those with locally advanced basal cell carcinoma, overall response rate was 43% and stable disease was observed in 40%. Median progression-free survival at 10 months was identical in the two groups. Absence of basal cell cancer on biopsy was reported in 54% of the cohort with locally advanced disease.. Few serious adverse events were attributed to vismodegib. Of 26 (25%) serious adverse events, 4 (4%) were deemed drug-related.

Author(s): Siddiqui, Fariha T | Abstract: Basal Cell Carcinoma Nevus Syndrome (BCCNS) is a multi-system genetic disease characterized by the development of multiple basal cell carcinomas (BCCs), macrocephaly, medulloblastomas, jaw keratocysts, and coarse facial features, amongst other symptoms. The major and minor criteria for adults with BCCNS are often extrapolated for children, however, little is known about the disease presentation of children with BCCNS. Our study focused on bringing the pediatric presentation of BCCNS to light. To the best of our knowledge, we are the first to investigate BCCNS and its medical impact on children. Using an internet accessible survey, we asked parents and guardians about the presenting symptoms of BCCNS in their children. It was found that at least 75% of children were diagnosed with BCCNS by the age of ten or earlier, which suggests that the presentation of disease starts much earlier than previously reported. Moreover, at least 19% of parents or guardians reported
Basal cell carcinoma is a common cutaneous malignancy.[1] It is considered as a disease of the fair skinned population, explaining the paucity of studies from developing countries. Jina et al. reported that skin changes were more common in males due to increased sun and chemical exposure.[9] Al-Zou et al. reported an increasing trend of basal cell carcinoma in southern governorates of Yemen.[10] A male preponderance with ulceroproliferative type of disease as the most common variety was found in a study conducted in 21 patients.[9] Kumar et al. noticed an increasing trend of BCC with female preponderance and involvement of nose.[11] Ammasaigoundan et al. also observed a female preponderance. They reported predominance of nodular variety of BCC in their study conducted in 30 patients.[12] Our findings of nodular type being the most common clinical form and nose being the most common site were consistent with the literature.[11-13]. We observed a higher number of females in our study and they did ...
A biopsy is often used to confirm a diagnosis of basal cell carcinoma. Once confirmed, basal cell carcinomas can be treated through:. Mohs micrographic surgery - Uses local anesthesia to remove tumors. Advantages of Mohs surgery include its ability to spare healthy tissue and a high cure rate of approximately 90 percent.. Excisional surgery - Unlike Mohs surgery, this procedure calls for the removal of small areas of surrounding healthy tissue as a preventive measure. Cure rates average about 90 percent.. Electrodessication and curettage - Also uses local surgery. Here, the growth is scraped off and cauterized to destroy any remaining tumor cells and to stop bleeding. Usually not suitable for advanced cases or for growths in hard-to-reach areas.. X-ray - Over the course of several weeks, beams are aimed precisely at the tumor. This option has the risk of radiation exposure.. Cryosurgery - Destroys tumors through freezing with liquid nitrogen.. Topical ointments - There are also ointments ...

This medical exhibit depicts a patch of skin with multiple basal cell carcinoma lesions. A single title label identifies basal cell carcinoma.
In 2012, two landmark phase II studies were reported in the New England Journal of Medicine investigating the use of the firstin- class, small-molecule SMO inhibitor vismodegib (GDC-0449, Genentech) for treatment of advanced BCC (both metastatic and locally advanced) and for management of patients with basal cell nevus syndrome (BCNS). By targeting the HH pathway, it was hoped that these medications could lead to lesion resolution and prevent the development of new BCC lesions. Both studies met their primary endpoints in terms of anti-BCC efficacy, although the studies demonstrated a moderate toxicity profile for the medication.. Sekulic and coworkers evaluated the efficacy and safety profile of vismodegib in BCC patients who were inappropriate surgical candidates given the low likelihood of cure or potential disfigurement of surgery. Of the 104 patients enrolled in the nonrandomized study, 33 had metastatic BCC, while 71 had locallyadvanced disease. Patients received vismodegib 150 mg daily by ...
Chemopreventive agents. Chemoprevention is the use of drugs, vitamins, or other agents to try to reduce the risk of cancer. The following chemopreventive agents have been studied to find whether they lower the risk of nonmelanoma skin cancer:. Beta carotene. Studies of beta carotene (taken as a supplement in pills) have not shown that it prevents nonmelanoma skin cancer from forming or coming back.. Isotretinoin. High doses of isotretinoin have been shown to prevent new skin cancers in patients with xeroderma pigmentosum. However, isotretinoin has not been shown to prevent nonmelanoma skin cancers from coming back in patients previously treated for nonmelanoma skin cancers. Treatment with isotretinoin can cause serious side effects.. Selenium. Studies have shown that selenium (taken in brewers yeast tablets) does not lower the risk of basal cell carcinoma, and may increase the risk of squamous cell carcinoma.. Celecoxib.

In normal development, Wnt5a is secreted and directs the migration of target cells along concentration gradients. The effect of Wnt5a on target cells is regulated by many factors, including the expression level of inhibitors and receptors. Dysregulated Wnt5a signalling facilitates invasion of multiple tumor types into adjacent tissue. However, the expression and distribution of Wnt5a in cutaneous squamous cell carcinoma (SCC) and basal cell carcinoma (BCC), as well as the effect ...

A method of treating a mammal for a condition of the skin or exposed tissue selected from the group consisting of basal cell carcinoma and actinic keratosis is provided. The method consists essentially of topically administering to the site of the condition, more than once per day over a period of days sufficient to treat the condition, a non-toxic effective dosage amount of a composition consisting essentially of (a) a non-steroidal anti-inflammatory drug (NSAID) in an amount sufficient to block prostaglandin synthesis, (b) hyaluronic acid or a pharmaceutically acceptable salt thereof in an amount effective to transport said NSAID into the skin or exposed tissue at the site of the condition. The concentration of the hyaluronic add or salt thereof is between 1-3% by weight of the composition. The molecular weight of the hyaluronic acid or salt thereof is between 150,000 and 750,000 Daltons. A pharmaceutical excipient suitable for topical application is included. The NSAID in the composition may be

BACKGROUND Oral hedgehog inhibitors (HHIs) have shown significant efficacy in the treatment of basal cell carcinoma (BCC). The evaluation of tumor regression has been performed using clinical photography and radiographic scans. Noninvasive imaging techniques, such as reflectance confocal microscopy (RCM) and high-definition optical coherence tomography (HD-OCT), have been shown to be valuable in detecting BCC in the skin. OBJECTIVE We monitored HHI-treated BCC using RCM and HD-OCT in vivo and correlated morphologic changes seen on imaging to changes in traditional histopathology. METHODS Six BCCs in 5 patients receiving HHIs (vismodegib or sonidegib) were examined by RCM and HD-OCT before and during treatment. Characteristic features were compared to histopathologic findings, including immunohistochemical analysis. RESULTS Characteristic features of BCC in RCM and HD-OCT decreased or disappeared completely during HHI treatment. Half of the clinically complete responding tumors still featured tumor
Normally, every cell has 2 copies of each gene: one inherited form the mother and one inherited from the father. NBCCS follows an autosomal dominant inheritance pattern, in which a mutation needs to happen in only 1 copy of the gene for a person to have the increased risk. This means that a parent with a gene mutation may pass along a copy of the normal gene or a copy of the gene with the mutation. Therefore, a child who has a parent with a mutation has a 50% chance of inheriting that mutation. A brother, sister, or parent of a person who has a mutation also has up to a 50% chance of having the same mutation. However, if the parents test negative for the mutation (meaning each persons test results found no mutation), the risk to the siblings significantly decreases but their risk may still be higher than an average risk. It is also possible that the NBCCS in an individual was caused not by an inherited mutation but, rather, by a spontaneous gene mutation (see below).. Options exist for people ...
