Cutaneous beta-papillomaviruses are associated with non-melanoma skin cancers that arise in patients who suffer from a rare genetic disorder, Epidermodysplasia verruciformis (EV) or after immunosuppression following organ transplantation. Recent studies have shown that the E6 proteins of the cancer associated beta human papillomavirus (HPV) 5 and HPV8 inhibit NOTCH and TGF-β signaling. However, it is unclear whether disruption of these pathways may contribute to cutaneous HPV pathogenesis and carcinogenesis...

We report the rare occurrence of a small bowel perforation secondary to a metastatic cutaneous squamous cell carcinoma (cSCC). A 70-year-old woman, who had previously undergone renal transplantation, presented with severe, sudden-onset abdominal pain. She was peritonitic on initial examination, with evidence of free intra-abdominal air on radiographic imaging. During an exploratory laparotomy, she was found to have a perforated jejunum secondary to disseminated metastases seen throughout her peritoneum. Following histopathological analysis, as well as further imaging studies, the primary malignancy was eventually identified as a cSCC on her upper back...

Non-melanoma cutaneous carcinomas, or skin cancers, predominantly squamous cell carcinomas (SCCs), are the most common malignancies occurring in kidney transplant recipients (KTRs). Squamous cell carcinoma risk is dramatically elevated in KTRs, occurring at rates of up 45-250 times those reported in general populations. New non-melanoma skin cancers in KTRs with a prior non-melanoma skin cancer also develop at 3-times the rate reported in non-KTRs with the same clinical history. The unique aggressiveness of SCCs in KTRs increases patient morbidity, due to the high rate of new lesions requiring treatment, frequently surgical excision...

Malignancies are one of the three major causes of renal recipient´s death with a functioning graft after cardiovascular diseases and infections. Among the variety of risk factors, including conventional and specific to transplant recipients, the duration of immunosuppressive therapy, the intensity of therapy, and the type of immunosuppressive agent all have an impact on development of post-transplant malignancy. The aim of our retrospective study was to document the incidence, the type of malignancies, the patient/graft survival in the group of kidney transplant recipients in Slovak Republic, and to identify the factors which influenced the outcome...

BACKGROUND: Organ transplant recipients have a highly increased risk of cutaneous squamous cell carcinomas. Sensation of pain in cutaneous tumours is a powerful patient-reported warning signal for invasive cutaneous squamous cell carcinomas in organ transplant recipients. OBJECTIVES: The impact of painful compared to painless skin lesions and cutaneous squamous cell carcinoma (SCC) compared to other skin lesions on the overall mortality risk in organ transplant recipients (OTR) was investigated...

The objective of this study was to investigate the role of ErbB3-binding protein 1 (Ebp1) in the growth of esophageal squamous cell carcinoma (ESCC) cells and the underlying mechanism. Eca109 and KYSE150 cells were transfected with lentiviral vector carrying Ebp1 gene. The mRNA levels of Ebp1 in esophageal cancer tissues and paired adjacent normal tissues were examined by real-time PCR. The growth and viability of esophageal carcinoma cells were assessed using MTT and crystal violet assays, respectively. Clone-forming abilities of Eca109 and KYSE150 cells were analyzed by soft agar assay...

PURPOSE: Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide. Although improvements in surgical techniques, chemotherapy and radiation delivery, and supportive care have improved quality of life for patients with HNSCC, regional and distant recurrence remain common. Recent evidence suggests that cancer stem-like cells (CSCs) play a significant role in recurrence and chemo-resistant. We previously observed that c-Fos was highly up-regulated in the HNSCC sphere forming cells...

Hereditary epidermolysis bullosa (EB) is a heterogeneous group of rare genetic diseases characterized by fragile skin and/or mucous membrane, and it may be either local or generalized. It is caused by mutations in genes encoding different proteins involved mainly in the structure and function of the dermal-epidermal junction. Nineteen genes have so far been identified. They are classified by level of skin cleavage (from top to bottom) into four groups: EB simplex, junctional EB, dystrophic EB and Kindler syndrome...

In the oral cavity, the tongue is the anatomic subsite most commonly involved by invasive squamous cell carcinoma. Current treatment protocols often require significant tissue resection to achieve adequate negative margins and optimal local tumor control. Reconstruction of the tongue while preserving and/or restoring its critical vocal, chewing, and swallowing functions remains one of the major challenges in head and neck oncologic surgery. We investigated the in vitro feasibility of fabricating a novel combinatorial construct using porcine small intestinal submucosa extracellular matrix (SIS-ECM) and human gingiva-derived mesenchymal stem cells (GMSCs) as a GMSC/SIS-ECM tissue graft for the tongue reconstruction...

Cutaneous squamous cell carcinomas (SCCs) account for up to 10,000 deaths annually in the United States. Most of the more than 700,000 SCCs diagnosed are cured by excision with clear margins; however, metastasis can occur despite seemingly adequate treatment in some cases. Immune-suppressed organ transplant recipients are 60 to 100 times more likely to develop SCC than immune-competent individuals. Transplant-associated SCCs occur more frequently and behave more aggressively, showing higher risk of recurrence and metastasis...

CD24 expression has been implicated in the oncogenesis of multiple types of cancer and high tumor expression is considered a poor prognosis factor; however, the role of CD24 in oral cancer progression is unknown. Unlike other cancer types, we found that higher CD24 levels in human oral cancers are correlated to lower clinical stage and better overall survival. We then dissected the role of CD24 and mechanisms in oral cancer pathogenesis in mice using a genetic strategy and demonstrated that CD24 deficiency increased the oral cavity tumor burden in response to the carcinogen 4-nitroquioline 1-oxide (4-NQO)...

BACKGROUND: Antiepidermal growth factor receptor (EGFR)-targeted therapy is widely used in many epithelial cancer types. We investigated lapatinib effects on cutaneous squamous cell carcinoma (cSCC) scheduled for resection and in coexisting precursor lesions (actinic keratosis (AK) and Bowen's disease (BD)) in a phase 2 mode of action clinical trial including a histological workup of the cSCC. PATIENTS AND METHODS: We initiated a prospective single-centre, open-label, non-controlled clinical study with translational intentions to investigate changes in size and histopathological features in cSCC after a 14-day period of neoadjuvant lapatinib therapy at a dose of 1500 mg/day prior to surgery, to quantify the impact on AK and BD in the same patient after 56 days and to evaluate the tolerability in patients with cSCC and precursor lesions...

Fanconi anemia (FA) is a rare genetic disease characterized by chromosomal instability and impaired DNA damage repair. FA patients develop oral squamous cell carcinoma (OSCC) earlier and more frequently than the general population, especially after hematopoietic stem cell transplantation (HSCT). Although evidence of an etiological role of the local microbiome and carcinogenesis has been mounting, no information exists regarding the oral microbiome of FA patients. The aim of this study was to explore the salivary microbiome of 61 FA patients regarding their oral health status and OSCC risk factors...
