Different expression of claudins and E-cadherin has been described in the pathogenesis and progression of breast cancer. Changes in the expression of these junctional molecules have also been described as being of prominent importance in other cancers as well. Thus, we aimed at exploring the potential prognostic relevance of these cell junctional molecules in breast carcinoma cases. ⋯ Evaluation of lymph node metastases has shown that decreased expression of claudin-1 and elevated expression of claudin-4 can predict worse prognosis in breast cancers spreading to the regional lymph nodes. The defined claudin-cadherin index provides additional prognostic information besides the routinely utilized diagnostic approaches and factors. The level of expression of certain claudins can be of prognostic significance in regional lymph node metastases.

Tailored therapy in lung cancer is one of the most exciting fields in translational research and also a nice example of fruitful collaboration between pulmonologists, clinical oncologists, pathologists and molecular biologists. This article, through a dialogue between a pathologist-clinician and a molecular biologist-pharmacologist, gives an overview about the most important questions on molecular targeted therapy in clinical practice, especially, EGFR-TKI treatment, EGFR activating mutations, as well as primary and acquired resistance.

The goal of this paper was to investigate the influence of FDG-PET/CT scan on the modification of staging and irradiation planning in patients suffering from non-small cell lung cancer (NSCLC). Fifteen patients suffering from NSCLC were analyzed by the authors from January, 2008 to July, 2009. The aim of the analysis was to examine the influence of FDG-PET/CT on irradiation planning and on decision-making of the complex oncologic therapy. ⋯ We likewise found a decrease in the mean dose load of the heart (17.3 Gy/16.8 Gy) and left ventricle (12.9 Gy/9.6 Gy). In the majority of the cases the FDG-PET/CT scan modified the therapeutic decision, the size of the irradiated volume, and the dose load of the lung, the organ at risk causing the most difficulties at irradiation planning, was also reduced. The PET/CT scan plays an essential role in the complex oncologic treatment and irradiation therapy of NSCLC.

Implementation of permanent prostate implant (PPI) brachytherapy in Hungary and presentation of initial experience. ⋯ This is a report of the first application of PPI in Hungary. The observed rate of acute proctitis was negligible, the rate and severity of acute cysto-prostatitis was tolerable. With the use of intraoperative planning, dose distributions met the dose-volume constraints in most of the cases. The biochemical control is excellent but the follow-up time is still short.

Breast screening programs along with advances in diagnostic methods and oncologic treatment have resulted in full recovery for a decisive number of patients diagnosed with early-stage breast cancer. The results of the ultra-radical-, followed by the breast conserving era pose new opportunities and challenges for the oncologic breast surgeon. ⋯ Modern procedures differ both in concept and technique from that of traditional breast surgery. This paper provides a comprehensive and detailed overview of reconstructive and oncoplastic breast surgery.
