BACKGROUND Lung carcinoma has a poor prognosis that is mainly predicted by the stage of the disease. Despite evaluation of various prognostic factors, the role of autophagy, a self-degradative process involved in the turnover of cytoplasmic material, remains unexplored in lung malignancy. METHODS Autophagic activity was investigated in 115 patients with(More)
Endocervicosis is considered a form of Mülleriosis affecting mainly the bladder and is comprised of endocervical-type glands and cysts. It has been rarely described in the uterine cervix where the extensive involvement of cervical and paracervical tissue poses the suspicion of malignancy, mostly minimal-deviation adenocarcinoma. We describe a case of(More)
BACKGROUND The survival of patients with malignant pleural effusion is considered generally poor. Most of the studies reporting results of prognostic factors are retrospective, using pleural thoracentesis for diagnosis. The objectives of our study were to reveal possible prognostic factors in patients initially presenting with undiagnosed pleural effusion(More)
Different histopathology and prognosis characterise the human papillomavirus (HPV)-related oropharyngeal tumours, but squamous cell carcinomas (SCC) of other localisations have not been exhaustively studied. Tissues from 120 patients with a head and neck SCC were studied for the expression of p16 and p53, and the Brandwein-Gensler (BG) histological risk(More)
This study was set to investigate the relation between autophagic activity and the aggressiveness of cutaneous squamous cell carcinomas (SCC), as indicated by tumor thickness and proliferative activity. The anti-LC3A antibody, recognizing both the soluble and the autophagosome-bound forms of the protein, and a standard immunohistochemical technique were(More)
BACKGROUND Immune system affects prognosis of various malignancies. Anti-immune pathways like PD-L1 and CTLA4 are used by the tumor to overcome immune system and they serve as immunotherapy targets. The immune microenvironment of head-and-neck squamous cell carcinoma (SCCHN) has not been sufficiently studied. PATIENTS AND METHODS 152 SCCHN were(More)
BACKGROUND/PURPOSE Malignant pleural effusion is a frequent situation in pulmonary medicine. However, it is sometimes difficult to recognize the underlying etiology. The aim of this review is to provide the key characteristics of primary and metastatic pleural neoplasms. METHODS A review of the recent literature regarding pleural neoplasia is provided. (More)
Primary pleural lymphoma is rare. It occurs in only 7% of lymphoma cases. We report herein two cases of primary pleural Hodgkin and non-Hodgkin follicular lymphomas diagnosed by thoracoscopy under local anesthesia. Both patients presented initially with dyspnea revealing pleural effusions. The pleural findings during thoracoscopy differed in the two cases(More)
Morphology, as confronted in the everyday practice, often correlates with specific molecular features, which have important implications not only in pathogenesis and in diagnosis but also in prognosis and therapy. Thus, it is important that the classical pathology includes a sound knowledge of molecular aspects of disease. These molecular concepts are(More)
