Background: Recently, lung cancer representing 5-7% of all cancers in Egypt with unavailable accurate epidemiological data. This study aims to identify characteristics, risk factors and histopathological types of bronchogenic carcinoma among a group of Egyptian patients.Methods: A cross sectional study was conducted on 123 cases of histopathological confirmed bronchogenic carcinoma presented to chest diseases department, Al-Zahraa Hospital, Al-Azhar University, Egypt in the period from July 2013 to May 2017. Statistical analysis of patients’ database was done using SPSS version 17.Results: Male to female ratio was 3.2:1; the majority of cases presented in their fifth (55.3%) and sixth (29.3%) decades of life, and urban: rural residence ratio was 2.1:1. Smoking was the most significant risk factor among 93.5% of cases, among them 65.9% were current smokers, 13.0% were ex-smokers and 14.6% were passive smokers. Occupational exposure to cement dust were reported among 47.2% of cases, 16.3% were farmers, 13.0% were employees, 8.9% were house wives, 8.1% were shoe makers and 6.5% were drivers. COPD was reported among 54.5% of cases. The commonest histopathological types were squamous cell carcinoma (31.7%), adenocarcinoma (30.9%), and large cell carcinoma (26.0%). Adenocarcinoma was the predominant type among females (55.3%), passive smokers (31.6%) and non-smokers (15.8%).Conclusions: Small cell lung cancer and squamous cell carcinoma subtypes were predominant among males, active smokers and workers exposed to cement dust. Adenocarcinoma was the commonest type among females, passive smokers and non-smokers. Conduction of anti-smoking campaigns; reduction of environmental pollution with regulation of occupational exposures to cement dust are recommended.

AbstractThe control of distant metastasis in oral squamous cell carcinoma is an important determinant of improved prognosis. The study aimed to identify risk factors for distant metastasis in patients with locoregionally controlled oral carcinoma. We identified 982 patients with oral squamous cell carcinoma treated at our hospital between January 2008 and December 2017. After excluding patients with distant metastasis at initial treatment, patients with metastasis to the oral cavity, those receiving palliative treatment, and those lacking follow-up data, 941 patients were selected. Finally, among these 941 patients, 887 with locoregionally controlled oral squamous cell carcinoma were included in the study. Among the 887 patients, 36 had confirmed distant metastasis (4.1%), and the lung was the most common site (31/36 patients, 86.1%). Multivariate analysis showed that the incidence of primary intraosseous carcinoma of the mandible, cervical lymph node metastasis at levels IV and V, and the presence of pathological extranodal extension were significant risk factors for distant metastasis. When treating patients with oral squamous cell carcinoma who are positive for the aforementioned risk factors, the possibility of developing distant metastases must be accounted for, and aggressive treatment should be planned accordingly.

Background and Aim. The relative frequency of histological subtypes of lung cancer in Europe has changed dramatically during the 20th century. The aim of this study was to explore the changing epidemiology of lung cancer in Northern Greece over the last two decades. Methods. From the extensive database of the Bronchoscopy Unit of the G. Papanicolaou General Hospital, Thessaloniki, Greece, we identified all patients with a histologic and/or cytologic report positive for lung cancer over two consecutive decades. Results. Between 1/1/1986 and 31/12/2005 we identified 9981 patients with specimens positive for lung cancer. A significant increase in mean patient age was observed during the second decade (64.8±9.4 vs. 62.1±8.9, p=0.001). Men developed lung cancer ten times more often than women. The predominant histological type was squamous cell cancer in males (4203 cases, 45.7%) and adenocarcinoma (418 cases, 52.6%) in females. The number of lung cancer cases was significantly higher during the second decade compared to the first decade (5766 cases [57.8%] vs. 4215 cases [42.2%], respectively, p<0.001). There was a significant decrease in the percentage of squamous cell carcinoma in males in the second decade (2317 cases [44.1%] vs. 1886 cases [48.0%], p<0.001), and an increase in adenocarcinoma (1021 cases [19.4%] vs. 609 [11.6%], p<0.001). In females, the relative incidence of adenocarcinoma was decreased and that of squamous cell carcinoma was increased, but not significantly. There was no obvious change in the incidence of small cell lung cancer. Neoplastic lesions were most often located in the upper lobes. Conclusion. The number of lung cancer cases has increased in the last decade. Squamous lung cancer appears to be decreasing in men and increasing in women. Adenocarcinoma appears to be increasing in men and decreasing in women. There appears to be no change in small cell lung cancer. During the second decade there has been a significant decrease in the male: female ratio.

Certain risk factors appear to separate subjects with repeated primary carcinomas of the lip from the general population of patients with carcinoma of the lip. Factors that were found statistically significant in increasing the chance of recurrent carcinoma of the lip include outdoor occupations requiring prolonged exposure to sunlight or the use of tobacco on a regular basis. Significant risk factors of a clinical nature include a positive serologic reaction for syphilis; the presence of leukoplakia, hyperkeratosis, or actinic cheilitis; or the presence of a basal cell or squamous cell carcinoma of the facial skin.

Background: Oral cavity is a common site for various non-neoplastic and neoplastic lesions. Majority of lesions were neoplastic. Tobacco chewing, smoking and alcohol consumption were the common risk factors implicated in the etiology of malignant oral lesions. Squamous cell carcinoma was the most common lesion of the oral cavity. Aims&Objectives: To study the clinicopathological lesions of the oral cavity with respect to age, gender, location, clinical presentation, histopathological patterns and various risk factors. Materials And Methods: A retrospective study of 274 oral cavity lesions conducted for period of 2 years from January 2019 to December 2020 in the department of pathology, Andhra Medical College, Visakhapatnam, Andhra Pradesh. Results: In our study, the age range of the patients was from 3 years to 87 years. Majority of cases were seen in age group of 41- 50 years. Males were more commonly affected than females with a male to female ratio of 2.51:1. Majority of oral lesions were malignant. Squamous cell carcinoma was the most common oral lesion. Tongue was the most common site involved in oral lesions. Mucocele was the commonest non-neoplastic lesion and squamous papilloma was the most common benign lesion. Leucoplakia was the most common premalignant lesion and Squamous cell carcinoma was the commonest malignant lesion. Conclusion: Majority of oral lesions were malignant. Squamous cell carcinoma was the most common oral lesion. Early and accurate identication of potentially malignant oral lesions is important and essential for prevention of morbidity, mortality and for proper treatment of cases. Along with clinical examination and laboratory investigations, histopathological examination is still the gold standard to establish a denitive diagnosis and for conrmation of the nature and origin of oral lesions.

7211 Background: The purpose of this study is to use a large patient population to identify immunohistochemical (IHC) biomarkers to enable improved prognostication in patients with non-small cell lung cancer (NSCLC). Methods: A tissue microarray was constructed using duplicate 0.6 mm cores of formalin-fixed paraffin embedded tissue blocks from 609 patients with NSCLC. IHC was used to detect 11 biomarkers including EGFR, HER2, HER3, p53, p63, Bcl-1, Bcl-2, TTF-1, CEA, Ch, and SNP. A clinical database was created prospectively at the time of tissue collection. Survival outcomes were obtained from a Provincial Cancer Registry database. Results: Male to female ratio was 400:209; median age 63yrs (range 35–82); median survival 3.5yrs (mean 5.7). All specimens were reviewed: 243 adenocarcinoma (ACA), 272 squamous cell carcinoma (SCC), 35 large cell carcinoma, 32 non-small cell carcinoma NOS, and 6 other (giant cell carcinoma). 21 patients with other histologies were excluded. Survival data for 535 cases was available. As of June 2005, 429 patients (80%) had died; of these 286 (54%) died of lung cancer, 117 (22%) died of other known causes, and for 26 (5%) the cause of death was not available. Bcl-2 (p = 0.007) was the only biomarker to predict better overall survival (OS). Bcl-2 (p = 0.021) and p63 (p = 0.025) were significant for disease specific survival (DSS) in all NSCLC. Analysis of the subgroups indicated that p63 was significant (p = 0.039) for DSS in squamous cell carcinoma (SCC) but not for adenocarcinoma (ACA) (p = 0.81). Bcl-2 was not significant for DSS in either subgroup (p = 0.28 for SCC, p = 0.112 for ACA). EGFR expression was associated with improved DSS in SCC (p = 0.012) but not for ACA. Co-expression of EGFR-HER3 was more likely in SCC then in ACA (p = 0.033). There was no correlation between outcome and any combination or clustering of biomarkers. Conclusions: The biomarkers p63 and Bcl-2 are predictive of DSS in NSCLC. EGFR expression is predictive of DSS in SCC. Sub-classification of NSCLC by histopathology is important as the relevance of some biomarkers (EGFR) would be lost if pooled. p63, Bcl-2, and EGFR may be used as prognostic markers in patients with NSCLC. Co-expression of EGFR-HER3 is more likely in SCC then in ACA. This may help explain the differential response to EGFR inhibitors in SCC versus ACA. No significant financial relationships to disclose.

Background: Lung cancer is the most common cancer causing deaths in men and women world-wide, responsible for over 1 million deaths annually. Although, advances in surgical techniques and combined therapies lung cancer remains a disease with a poor prognosis. Aim of the study was to evaluate the clinico-epidemiological and pathological profile in diagnosed case of lung cancer patients, presenting in the K N Chest hospital.Methods: Initial evaluation after obtaining informed consent, demography, history, clinicoradiological findings of patients and relevant investigations was recorded. Histopathological reports reviewed.Results: Our study included 108 patients with confirmed cases of lung cancer.The mean age of the patients was 57.50 years. The male:  female ratio was 5.8:1. Cough was the most common presenting symptom (77.78%) followed by chest pain (62.33%). Clubbing was most commonly associated with squamous cell carcinoma. Most common radiological presentation was consolidation (42.59%) followed by mass lesion (30.55%). Most common histopathological type of lung cancer found in this study was squamous cell carcinoma 47(43.52%) followed by adenocarcinoma 42 (38.89%). Small cell carcinoma was present in 15 (13.89%) and large cell carcinoma was present in 4 (3.70%) study group. The most common pathological cell type in silica dust exposed patient in this study was squamous cell carcinoma followed by adenocarcinoma with occupational history of > 10 years of silica dust exposure in stone mines.Conclusions: Squamous cell carcinoma still remains the commonest histological subtype followed by adenocarcinoma.
