BACKGROUND: Immunotherapy can become a crucial therapeutic option to improve the prognosis of patients with non-small-cell lung cancer (NSCLC). Here, we evaluated the impact of programmed cell death ligand-1 (PD-L1) expression in surgically resected NSCLCs. METHODS: We estimated PD-L1 expression in 229 consecutive NSCLC specimens using rabbit polyclonal antibodies to human PD-L1 in a SP263 immunohistochemical assay and evaluated PD-L1 expression for potential associations with clinicopathological parameters and survival time...

BACKGROUND: Radioresistance is a common feature of head and neck squamous cell carcinoma (HNSCC). We previously showed that the irradiation- activated vascular endothelial growth factor (VEGF)-extracellular signal-regulated kinase (ERK)-axis is fundamental for the survival of resistant tumors. In this study, we examined if treatment with potent multikinase (MK) inhibitors, sorafenib and sunitinib, could radiosensitize tumor cells. METHODS: Cultured HNSCC cell lines were treated with inhibitors and subsequently irradiated...

A 63-year-old woman presented with a large, ulcerokeratotic mass in her right lower eyelid that had grown over the last 2 months in a burn scar. She had experienced a thermal burn involving both inferior periorbital areas 35 years ago and received medical treatment. The lesion was excised with wide margins. The histologic diagnosis was squamous cell carcinoma. No recurrence was observed during a 22-month follow up. In the previous literature, a total of 10 cases of eyelid burn scar neoplasm, of which 9 were basal cell carcinoma, have been reported...

Bmi-1, CD133, Nanog and Oct-4 have been reported as cancer stem cell (CSC) markers in head and neck squamous cell carcinoma (HNSCC). However, the prognostic value of them in HNSCC remains controversial. Hence, this meta-analysis was conducted to access the association between the four CSC markers and survival outcome of HNSCC patients. A total of 22 articles with 27 studies met the inclusion criteria and the combined hazard ratio (HR) and 95% confidence intervals (95% CI) were calculated. Data analysis showed that high expression of CSC markers was associated with poor overall survival (OS) (HR = 1...

BACKGROUND: Cancer incidence typically increases with age, but it is not known whether ethnic characteristics influence the age dependence of squamous cell carcinoma of the skin (SCC). OBJECTIVES: (i) To determine the age dependence of SCC in the black African, coloured and white population groups of South Africa (SA); and (ii) to show whether any differences in the rate of change of age dependence could be influenced by diversity in behaviour and lifestyle, especially with regard to the prevalence of HIV infection, rather than by a fundamental variation in cancer biology between the populations...

CDK8, a member of the transcriptional subtype of the cyclin-dependent kinases (CDKs) family, shows remarkable cancer tissue specific expression profile and rather more selective contribution to the regulation of gene expression levels involved in some signaling pathways. However, the effect of CDK8 on the malignant phenotype of human laryngeal squamous cell carcinoma (LSCC) cells and the potential molecular mechanisms remain unclear. In the present study, we evaluated the expression levels of CDK8 by quantitative real-time reverse-transcriptase polymerase chain reaction (qRT-PCR) and immunohistochemistry in tissue samples of 60 LSCC patients...

PURPOSE: Denosumab reduces the incidence of skeletal-related events (SREs) in solid tumor patients with bone metastases (BM). However, there have been no detailed reports of the efficacy of denosumab in untreated non-squamous non-small cell lung cancer (NSCLC) patients with BM. METHODS: The medical records of patients with untreated non-squamous NSCLC and BM at diagnosis at our institution were reviewed retrospectively. The overall survival (OS) and the time to SREs were analyzed according to the treatment for the BM...

Squamous cell carcinoma of thyroid is an uncommon, very aggressive neoplasm, having a poor prognosis and poor response to chemotherapy and radiotherapy. Surgery is the initial treatment of choice, although it often presents as a widespread disease at the time of diagnosis, usually with cervical swelling that causes most of the symptoms due to local infiltration or metastasis. Local infiltration from adjacent tumour and metastatic disease needs to be excluded from other primary epidermoid carcinomas, in order to make a correct diagnosis...

OBJECTIVES: In renal transplant recipients, the risk of developing bladder cancer and rate of diagnosis of advanced staged bladder cancer are generally higher than the general population. Also, it is more challenging to treat renal transplant recipients than the regular patient population. We aimed to evaluate the efficacy and safety of radical cystectomy (RC) and urinary diversion with ileal conduit in renal transplant recipients. METHODS: We identified 2 patients with prior history of renal transplantation who underwent RC and ileal conduit urinary diversion for bladder cancer...

Squamous cell carcinomas occurring at transition zones are highly malignant tumors with poor prognosis. The identity of the cell population and the signaling pathways involved in the progression of transition zone squamous cell carcinoma are poorly understood, hence representing limited options for targeted therapies. Here, we identify a highly tumorigenic cancer stem cell population in a mouse model of transitional epithelial carcinoma and uncover a novel mechanism by which loss of TGFβ receptor II (Tgfbr2) mediates invasion and metastasis through de-repression of ELMO1, a RAC-activating guanine exchange factor, specifically in cancer stem cells of transition zone tumors...

EGFR tyrosine kinase inhibitors (TKIs) treatment has been established as standard therapy for EGFR-mutated adenocarcinomas. In the studies which published prospective randomized trials comparing EGFR TKIs with chemotherapy, a very low percentage of EGFR-mutated non-adenocarcinomas was enrolled in clinical trials. The efficacy of TKIs treatment for EGFR-mutated non-adenocarcinomas and their relationship with clinicopathological characteristics remain debatable. The results of retrospective studies show that the frequency of EGFR mutation is lower in non-adenocarcinoma than that of adenocarcinoma and efficacy of TKIs treatment for non-adenocarcinoma is inferior to adenocarcinoma...

Circulating tumor cells are tumor cells from the primary tumor or metastatic tumor to fall off into the circulatory system. They are closely related to the recurrence and metastasis of tumor. Detection of circulating tumor cells as a "liquid biopsy" , to get the tumor information through non-invasive sampling method. It has the advantages of short time of tumor diagnosis, repeatable operation, and has gradually replaced the traditional biopsy. In this paper, the enrichment and detection of circulating tumor cells and its application in head and neck squamous cell carcinoma were reviewed...

Head and neck squamous cell carcinoma(HNSCC) is the sixth most common malignancies of human beings. The prognosis of advanced HNSCC is poor despite improvements in traditional treatment strategies including surgery, chemotherapy, and radiotherapy. Cancer immunotherapy is the use of the immune system to treat cancer, which provides a sustained antitumor reaction but an absense of chemoresistance. Cancer immunotherapy is becoming the forth treatment strategy towards cancer. Therefore, we reviewed the current state of immunotherapy for HNSCC...

Soft palatal melanosis can be detected by visual inspection during routine physical examination or even personally in a mirror. The aim of this study was to evaluate the association between squamous cell neoplasia in the upper aerodigestive tract (UAT) and the soft palatal melanosis. We reviewed digitalized records of high-quality endoscopic images of the soft palate of 1786 Japanese alcoholic men who underwent endoscopic screening. Soft palatal melanosis was observed in 381 (21.3%) of the subjects (distinct, 6...

Up-to-date, several molecular markers of prognosis have been studied in Oral Squamous Cell Carcinoma (OSCC), but none entered in the clinical setting. Therapy of OSCC tumors mainly relies on surgery, radiotherapy and partially on chemotherapy; there is an urgent need for biomarkers able to better stratify OSCC patients' risk to address targeted therapeutic strategies. The role of immune response in the pathogenesis and biological behavior of OSCC has been investigated by several authors, and promising results have been obtained with immune checkpoint inhibitors...

BACKGROUND: Skin cancer is one of the most common cancers in the UK. Patients with suspicious skin lesions are assessed clinically with/without dermoscopy, and lesions still considered suspicious are then surgically removed or have the diagnosis confirmed by a punch biopsy. AIM: To evaluate the diagnostic accuracy of the in vivo VivaScope(©) reflective confocal microscopy (RCM) system, a noninvasive technology designed to provide a more accurate presurgical diagnosis, leading to fewer biopsies of benign lesions, or to provide greater accuracy for lesion margins...

There is uncertainty about the risk of developing non-melanoma skin cancer (NMSC), including basal cell carcinoma and squamous cell carcinoma (SCC), in patients with atopic dermatitis (AD) treated with oral immunosuppressive drugs. A total of 557 patients with AD treated with these drugs in the University Medical Center Utrecht and Groningen, the Netherlands, were analysed. NMSC after oral immunosuppressive treatment was reported in 18 patients (3.2%). The standardized incidence ratio for developing SCC was 13...
