Immunohistochemical Profile

The etiological factors of squamous cell carcinomas of the head and neck have been well known for a long time. It is also well known that the incidence of oral cancer diagnosed in younger patients is on the rise. Due to the young age of these patients, the increase in the number of these cases and the fact that many of them neither smoke nor drink alcohol it has been suggested that other factors might be at play in the carcinogenesis of oral cancer. Thus, along the classic etiological factors of smoking and alcohol abuse certain molecular marker anomalies and the human papilloma virus (HPV) have emerged as potential factors. The aim of the present study is to verify the potential prognostic factors and to map the differences in biomarker expression between the young and the old patient groups. In the present study the immunohistochemical profile of samples obtained from oral squamous cell carcinomas was studied and compared with various clinico-pathological parameters. In 88 samples the expressions of p16, p53, Ki67, EGFR were studied with a tissue microarray technique under standard reaction conditions as well as the detection and typing of HPV infection with the Full Spectrum HPV DNA method. The biomarker expression profile of young patients with oral squamous cell carcinoma was compared to that of older patients (above 50). A significant difference was found between the immunohistochemical profile of the young and old patient groups in p16, Ki67 expression. The overall survival and progression free survival were influenced by p16 expression in young age.

Biological Behaviour

It is common knowledge that apparently similar tumors often show different responses to therapy. This experience has generated the idea that histologically similar tumors could have biologically distinct behaviour. The development of effective therapy therefore, has the explicit challenge of understanding biological behaviour of a tumor. The question is which parameters in a tumor could relate to its biological behaviour ? It is now recognised that the development of malignancy requires an alteration in the program of terminal differentiation in addition to aberrant growth control. In this study therefore, ultrastructural markers that relate to defective terminal differentiation and possibly invasive potential of cells have been identified in human oral leukoplakias, erythroleukoplakias and squamous cell carcinomas of the tongue.

There were studied 92 somatically healthy persons of young age (18-25 years old), with generalized periodontitis (GP) of initial-I degree of development, among them: 30 patients with chronic generalized periodontitis (CGP), who were included into group І; and 32 patients with exacerbation of the chronic generalized periodontitis (ECGP) – into group II; and 30 healthy patients. The carbohydrate metabolism indexes were studied, namely: the content of glucose, pyruvate (pyruvic acid) and lactate (lactic acid) and lactate dehydrogenase activity (LDG) in the oral liquid.We have determined that in the presence of CGP of the initial-I degree of development, and especially in its exacerbation, there is a significant increase of indicators of carbohydrate metabolism. In young patients with CGP indicators of glucose, pyruvate, lactate and LDG activity in the oral liquid increased by 2.0, 1.34, 1.58 and 1.37 (p<0.001, p<0.01) times respectively, and in case of ECGP they grew even more: by 2.71, 1.98, 1.76 and 2.07 (p<0.001) times, respectively.Among all the indicators, that characterize the carbohydrate metabolism, in addition to the level of pyruvate, in case of different course of GP a significant difference was revealed: in patients with ECGP compared with the data in CGP, glucose and lactate levels and LDG activity in the oral liquid were significantly higher - at 35.75% (p<0.05), 34.29% (p<0.01) and 36.59% (p<0.001) respectively.Detected violations of carbohydrate metabolism indeces in the oral liquid indicate the involvement of these processes in the pathogenesis of GP and the necessity of their correction.

P16 Expression

Abstract Context.—Distinguishing between keratoacanthoma (KA) and squamous cell carcinoma (SCC) is not an uncommon histologic diagnostic dilemma. Objective.—To determine if p16 expression is useful in the differential diagnosis of SCC and KA. Design.—We studied the expression of p16 by immunohistochemistry in 24 KAs, 24 infiltrating SCCs of the skin, 4 histologically indeterminate lesions, and 8 nonmalignant keratoses. Results.—A range of immunohistochemical p16 expression was seen in KAs and SCCs in terms of the thickness of lesional staining and the percentage of cells staining. No significant difference in measures of p16 expression was identified among the KAs, the SCCs, the indeterminate lesions, or the benign keratoses. Conclusions.—These findings suggest that p16 is not a useful marker to distinguish between KA and SCC, supporting the similarity between the 2 lesions; p16 alterations appear to play a role in the pathogenesis of both KA and SCC.

Objective. Oral squamous cell carcinoma (OSCC) has a remarkable incidence over the world and a fairly strenuous prognosis, encouraging further research on the prognostic factors and new techniques for diagnosis that might modify disease outcome. Data Sources. A web-based search for all types of articles published was initiated using Medline/Pub Med, with the key words such as oral cancer, prognostic factors of oral cancer, diagnostic method of oral cancer, and imaging techniques for diagnosis of oral cancer. The search was restricted to articles published in English, with no publication date restriction (last update April, 2013). Review Methods. In this paper, I approach the factors of prognosis of OSCC and the new advances in diagnostic technologies as well. I also reviewed available studies of the tissue fluorescence spectroscopy and other noninvasive diagnostic aids for OSCC. Results. The outcome is greatly influenced by the stage of the disease (especially TNM). Prognosis also depends or varies with tumour primary site, nodal involvement, tumour thickness, and the status of the surgical margins. Conclusion. Tumour diameter is not the most accurate when compared to tumour thickness or depth of invasion, which can be related directly to prognosis. There is a wide agreement on using ultrasound guided fine needle aspiration biopsies in the evaluation of lymph node metastasis.
