Introduction. Thymoma is the most common tumour of the anterior mediastinum. Video-Assisted Thoracic Surgery technique of thymoma resection is spreading world-wide, but the thoracoscopic method is still contentious in many ways.

Completion pneumonectomy (CP) means the removal of the entire residual lung tissue after previously performed lung resection. Mortality and morbidity of CP are higher when compared to those of standard pneumonectomy. In this article, we give an overview on indications and perioperative results of CP.

Infrequent solitary fibrous tumours of the pleura are associated with hypoglycaemia only in a few percent of the cases; this condition is called Doege-Potter syndrome, named after its first descriptors. Our 63 years old male patient has previously undergone clinical treatment for intrathoracic fluid accumulation on the left side caused by a giant tumour-like mass in the lower left lobe detected by CT scan. In the course of further investigations performed due to increasing load-induced dyspnoea, lung core biopsy verified low grade sarcoma in the tumour.

Surgery of mostly benign giant tumours involving large part of the chest is a special surgical challenge. The problems comprise difficulties of surgical technique, management of the narcosis and postoperative intensive care. An additional peculiarity of our case is the extreme confliction of the otherwise presumably evident indication for surgery.

Aims: To assess the expression of the following cell cycle regulatory proteins in primary metastatic breast carcinomas (MBCs) and on availability in matched distant metastases (DMs): Ki67, cyclin A, geminin and aurora-kinase A (aurkA); and to compare the expression of these markers in early MBC (EMBC) and late MBC separated into groups according to median time point on metastatic event occurred (28 months).

Methods: The expression of the above mentioned markers was analysed in a total of 47 primary MBCs and 59 DMs (out of which 37 were pairs) by immunohistochemistry. Fourteen breast carcinomas with no relapse over a 10-year follow-up period were utilised as control cases (CBC).

Lung cancer rate in Hungary is one of the highest in the world among men and also very high among women, for reasons not clearly understood yet. The aim of the study was to explore characteristics of DNA damage and TP53 gene mutations in lung cancer from Hungary. Tissue samples from 104 lung resections for lung cancer patients, both men and women, operated on for non-small cell lung cancer, specifically, primary squamous cell carcinoma or adenocarcinoma were studied.

Background: Primary pulmonary choriocarcinoma (PPC) is an extremely rare clinical entity. In contrast with gestational trophoblastic tumors that show an extreme sensitivity for chemotherapy, extragonadal choriocarcinomas are mostly unresponsive to surgical and chemotherapeutic treatment and are associated with poor prognosis. The reason non-gestational choriocarcinomas behave so differently from gestational tumors is unknown.

Purpose: Claudins are the main constituents of tight junctions. Little is known about their expression and localization in the normal bronchial epithelium and in lung cancer.

Patients And Methods: One hundred four lung cancer tissue blocks were studied including 46 adenocarcinomas (ADC), 30 squamous cell carcinomas (SCC), 15 small cell lung cancers (SCLC), 8 typical and 5 atypical carcinoids.

The aim of this study was to test whether donor and recipient gender influence the development of obliterative airway disease in an established rat model of human bronchiolitis obliterans. Rat tracheas were transplanted from male and female Brown-Norway donors into male and female Lewis recipients. Grafts were harvested at days 7, 14 and 21 for morphometric studies and molecular analysis by real-time PCR.

Purpose: Recent experimental studies have revealed that lymphangiogenesis plays an important role in cancer progression, but its clinical significance in the case of non-small cell lung cancer (NSCLC) remains unclear. Our aim was to assess the lymphangiogenesis of human NSCLC, and to correlate this with angiogenic phenotype (angiogenic versus nonangiogenic growth pattern) and clinical behavior.

Experimental Design: One hundred and three patients with NSCLC and complete follow-up information were included.

Smoking is a major risk factor for lung cancer. This comparative study of smoking-related carcinogen-DNA adducts in pulmonary tissues and peripheral blood lymphocytes aims to further explore the primary DNA damaging processes by cigarette smoke in target and surrogate tissues. Samples of tumour and normal peripheral lung tissue, normal bronchial tissue and peripheral blood lymphocytes were obtained from a total of 85 lung cancer patients who underwent lung resection.
