REVIEW
P Arenberger, M Arenbergerova
Actinic keratosis (AK) is a characteristic skin lesion on skin areas of subjects with mainly phototype I and phototype II, or with specific genetic factors and who are exposed to prolonged ultraviolet radiation. AK may be considered a precursor of in situ squamous cell carcinoma (SCC), a type of non-melanoma skin cancer (NMSC). However, it is still not possible to predict which AK lesions will develop into SCC. Early treatment of AK is therefore recommended. Despite the increasing number of patients with AK developing into SCC, to date, there is still no clear suggestion of therapeutic strategy for AK...

Targeted microbubbles has the potential to be used for ultrasound (US) therapy and diagnosis of various cancers. In the present study, US was irradiated to oral squamous cell carcinoma cells (HSC-2) in the presence of cetuximab coated albumin microbubbles (CCAM). Cell killing rate with ultrasound treatment at 0.9W/cm(2) and 1.0W/cm(2) in the presence of CCAM was greater compared to non-targeted albumin microbubbles (p < 0.05). On the other hand, selective cell killing was not observed in human myelomonocytic lymphoma cell line (U937) that had no affinity to cetuximab...

This case report describes an 86-year-old woman with dormant right buccal squamous cell carcinoma who was able to maintain a reasonable quality of life after being treated with oral low-dose S-1 (80 mg/day). The treatment regimen started in April 2014 and consisted of two weeks of S-1 followed by a one-week interval. The patient remains on this regimen while maintaining her quality of life and she has been under follow-up as an outpatient for 36 months. The outcomes for this patient indicated that low-dose S-1 is a valid anticancer therapy that may help maintain quality of life for some patients with incurable or dormant cancers...

Head and neck cancer (HNC) includes a diverse range of malignancies arising commonly from mucosal epithelia of the upper aerodigestive tract. Head and neck squamous cell carcinoma (HNSCC), the most common form of HNC, develops in the oral cavity, pharynx, and larynx and is associated with tobacco exposure, alcohol abuse, and infection with oncogenic viruses. Despite global advances in cancer care, HNSCC often presents with advanced disease and is associated with poor 5-year survival of ~50%. Genotyping tumor tissue to guide clinical decision-making is becoming commonplace in modern oncology, but in the management of HNSCC, tissue biopsies with cytopathology or histopathology remain the mainstay for diagnosis...

Cancer stem cells (CSC) have been investigated as prognostic markers in oral squamous cell carcinoma (OSCC). However, an assessment of the reporting quality of these studies has not been performed yet. The aim of this study was to describe the reporting quality of prognostic studies involving CSCs and OSCC, focusing mainly on the immunohistochemical reproducibility. By means a systematic review, 34 articles were selected. Analyses of both general reporting quality and immunohistochemistry technique were performed by using checklists for multiple aspects related to study reproducibility...

Pemphigus vulgaris (PV) is a chronic autoimmune bullous disease characterized by the formation of suprabasal cleavage and acantholysis. As this disease almost always affects the oral mucosa, conventional cytological smears of oral lesions can be used for the initial diagnosis of PV. We report two cases of PV that were initially diagnosed based on cytological smears of an oral sample. As atypical squamous cells were present even in the liquid-based cytological (LBC) smears of the oral lesion in these two cases, this ultimately led to the misinterpretation of squamous cell carcinoma...

Human papillomavirus (HPV) 16 is the most common high-risk HPV type identified in oropharyngeal and cervical neoplasia. Recently, HPV-associated oral epithelial dysplasia with specific histopathologic features and demographics similar to HPV-oropharyngeal carcinoma has been identified. The objective of this study was to evaluate histopathologically all cases of HPV-oral epithelial dysplasia seen in one center and identify HPV types in a subset of cases. Cases with specific histopathology for HPV-oral epithelial dysplasia that were positive both by immunohistochemical studies for p16 and by in situ hybridization for high-risk types of HPV were further analyzed using QIAamp DNA Tissue Kits (Qiagen, Hilden, Germany)...

PURPOSE OF REVIEW: Prognosis of advanced oral squamous cell carcinoma remains a challenge for clinicians despite progress in its diagnosis and treatment over the past decades. In this review, we assessed clinicopathological factors and potential biomarkers along with their prognostic relevance in an attempt to develop optimal treatment strategies for these patients. RECENT FINDINGS: In addition to several pathologic factors that have been proposed to improve prognostic stratification and treatment planning in the eighth edition of the American Joint Committee staging manual on cancer, we reviewed some other imaging and clinicopathological parameters demonstrated to be closely associated with patient prognosis, along with the biomarkers related to novel target or immune therapy...

Natural products with medicinal value are gradually gaining importance in clinical research due to their well-known property of no side effects as compared to drugs. Tinospora cordifolia (Guduchi) has been used for centuries in Ayurvedic system of medicine for treating various ailments including cancer. In present study, we found that the Tinospora cordifolia extracts (TCE) induced inhibition of proliferation of KB cells was associated with arrest of G0/G1-phase of cell cycle. The effectiveness of TCE in checking the growth of KB cells without altering the growth of normal peripheral blood mononuclear cells (PBMC) indicates that Tinospora cordifolia has differential effect on normal and malignant cells hence, it may have therapeutic potential in cancer...

OBJECTIVES: Conditional relative survival (CRS) describes the survival chance of patients who have already survived for a certain period of time after diagnosis and treatment of cancer. Thus, CRS can complement the conventional 5-year relative survival, which does not consider the time patients have survived after their diagnosis. This study aimed to assess the 5-year CRS among Korean patients with oral cancer and the related risk factors. MATERIALS AND METHODS: We identified 15,329 oral cavity cancer cases with a diagnosis between 1993 and 2013 in the Korea Central Cancer Registry...

Over the years, several tumor biomarkers have been suggested to foresee the prognosis oral squamous cell carcinoma (OSCC) patients. Here, we present a systematic review to identify, evaluate and summarize the evidence for OSCC reported markers. Eligible studies were identified through a literature search of MEDLINE/PubMed until January 2016. We included primary articlesreporting overall survival, disease-free survival and cause-specific survival as outcomes. Our findings were analysed using REporting recommendations for tumor MARKer prognostic studies (REMARK), QuickGo tool and SciCurve trends...

OBJECTIVE: Squamous cell carcinomas (SCC) are the most common malignancies in the oral mucosa; these carcinomas have been preceded by potentially malignant oral disorders (PMODs), mostly oral leukoplakia (OL). No specific biomarker has been widely accepted for predicting the risk of malignant transformation of PMODs. The aim of this study was to develop an accurate prediction model for the malignant transformation of OL using clinical variables and candidate biomarkers. MATERIALS AND METHODS: To achieve this goal, 10 candidate biomarkers that had previously been reported as useful molecules were investigated: P53, Ki-67, P16, β-catenin, c-jun, c-met, insulin like growth factor II mRNA-binding protein (IMP-3), cyclooxygenase (COX-2), podoplanin (PDPN) and carbonic anhydrase 9 (CA9)...

INTRODUCTION: Immunosuppression after solid organ transplant prevents graft rejection, but leads to increased incidence of various malignancies including head and neck squamous cell carcinoma (HNSCC). Outcomes of patients with post-transplant HNSCC are unknown. MATERIALS AND METHODS: We retrospectively identified patients who developed HNSCC after solid organ transplant between 1995 and 2010. Adults with pathology-proven HNSCC and adequate follow up were included...

Radiotherapy is one of the most effective non-surgical treatments for oral squamous cell carcinoma. However, radioresistance remains a major impediment to radiotherapy. Although BetA (Betulinic acid) can induce radiosensitization, the underlying mechanism and whether it could induce radiosensitization in oral squamous cell carcinoma are not fully understood. In this study, we showed that BetA increased radiosensitization in CAL-27 and Tca-83 cells. Radiation-triggered Sp1 overexpression was responsible for radioresistance of OSCC (oral squamous cell carcinoma) cells...

NOTCH1 is known as an oncogenic or tumor suppressive gene in solid cancer. NOTCH1 mutations in oral squamous cell carcinoma (OSCC) frequently occur near the ligand-binding region. These mutations change the domain structure of this protein and affect the ligand binding activity. When NOTCH1 is activated by ligand binding, NOTCH1 intracellular domain (NICD) is cleaved from the cell membrane. This study investigated the functional change induced by a NOTCH1 mutation detected in OSCC clinical samples using stable transformant analysis...

Oral squamous cell carcinoma (OSCC) is one of the most common malignancies worldwide. Diphenyldifluoroketone (EF24) is a curcumin analog that has been demonstrated to improve anticancer activity; however, its therapeutic potential and mechanisms in oral cancer remain unknown. In the present study, the effect of EF24 on apoptosis induction and its potential underlying mechanism in the CAL‑27 human OSCC cell line was investigated. To achieve this, various concentrations of cisplatin or EF24 were administrated to CAL‑27 cells for 24 h, and cell viability, apoptotic DNA fragmentation, and cleaved caspase 3 and 9 levels were evaluated...
