Study on breast carcinoma Her2/neu and hormonal receptors status assessed by automated images analysis systems: ACIS III (Dako) and ScanScope (Aperio).

Her-2/neu is overexpressed in 20-30% of breast cancer patients and is associated with a more aggressive disease. Identification of Her-2/c-erbB-2-neu overexpression is based on immunohistochemical [ihc] detection of protein and/or gene amplification in fluorescence in situ hybridization test (FISH). Also Estrogen receptors [ER] and Progesterone receptors [PR] are the prognostic and predictive biomarkers, recently analysed by ihc methods. Subjective, manual scoring of the ihc Her-2/neu expression and expression of the ER/PR reported as the percentage of immunopositive cells are the most common mode of interpretation among pathologists. Automated microscopy and computerised processing have provided increased accuracy in quantification and standardisation. The aims of our study were: to evaluate the scoring reproducibility of Her-2 /neu ihc expression tested by two automated systems: ACIS (Dako) and ScanScope (Aperio); to estimate the ER/PR expression in ihc staining methods with different anti-ER/anti-PR antibodies (the monoclonal and the ER/PR pharmDx TM Kit) by the ACIS system. Her-2/neu ihc expression was measured in 114 primary invasive breast carcinomas by the manual and the automated scoring (ACIS and Aperio system). 106 slides stained ihc with two types of anti-ER/anti-PR antibodies entered the quantisation. The results of our investigations showed very high reproducibility of Her-2/neu scores in intra- and interobserver analysis by ACIS evaluation. The major concordance was present in strong 3+ ihc cases; very small discordance was shown by cases with low expression of Her-2/neu. The accuracy of scoring by the Aperio was little lower in comparison to ACIS but it might result from the smaller and variable series of samples analysed by Aperio. The concordance in scoring of two automated systems was 86.5% (

Role of catheter-directed therapies in the treatment of acute pulmonary embolism. Expert opinion of the Polish PERT Initiative, Working Group on Pulmonary Circulation, Association of Cardiovascular Interventions, and Association of Intensive Cardiac Care

Thanks to advances in interventional cardiology technologies the catheter-directed treatment has become recently a viable therapeutic option in the treatment of patients with acute pulmonary embolism at high risk of early mortality. Current transcatheter techniques allow local fibrinolysis or embolectomy with minimal risk of complications. Therefore they can be considered in high risk patients as an alternative to surgical pulmonary embolectomy when systemic thrombolysis is contraindicated or ineffective. They are also considered in patients with intermediate — high risk with a lack of improvement or clinical deterioration despite anticoagulation. The purpose of this article is to present the role of transcatheter techniques in the treatment of patients with acute pulmonary embolism. We describe current knowledge and experts’ opinion in this field. Interventional treatment is described in the broader context of patient care organization and therapeutic modalities. We present the organization and responsibilities of pulmonary embolism response teams, the role of pre-procedural imaging, peri-procedural anticoagulation, patients selection, timing of intervention and intensive care support. Currently available catheter directed therapies are discussed in detail including standardized protocols, definitions of procedure success and failure. This expert opinion has been developed in collaboration with experts from various Polish scientific societies signifying the role of teamwork in the care for patients with acute pulmonary embolism

Rola terapii przezcewnikowych w leczeniu ostrej zatorowości płucnej — opinia Polskiej Inicjatywy PERT, Sekcji Krążenia Płucnego, Asocjacji Interwencji Sercowo-Naczyniowych i Asocjacji Intensywnej Terapii Kardiologicznej Polskiego Towarzystwa Kardiologicznego

Dzięki postępom w zakresie technologii kardiologii interwencyjnej leczenie przezcewnikowe stało się w ostatnich latach realną opcją terapeutyczną w leczeniu pacjentów z ostrą zatorowością płucną z wysokim ryzykiem wczesnej śmiertelności. Obecnie stosowane techniki przezcewnikowe umożliwiają miejscową fibrynolizę lub embolektomię przy minimalnym ryzyku powikłań. Stąd mogą być rozważane u pacjentów z grupy wysokiego ryzyka jako alternatywa dla chirurgicznej embolektomii płucnej, gdy systemowa tromboliza jest przeciwwskazana lub nieskuteczna. Rozważane są również u pacjentów z grupy średniego–wysokiego ryzyka, u których pomimo leczenia przeciwzakrzepowego nie uzyskano poprawy lub nastąpiło pogorszenie stanu klinicznego. Celem artykułu było przedstawienie roli technik przezcewnikowych w leczeniu chorych z ostrą zatorowością płucną zgodnie z aktualną wiedzą i opinią ekspertów. Leczenie interwencyjne opisano w szerszym kontekście organizacji opieki nad pacjentem. Przedstawiono organizację i zadania zespołu szybkiego reagowania w zatorowości płucnej, rolę obrazowania przedzabiegowego, zasady antykoagulacji okołozabiegowej, kryteria kwalifikacji pacjentów, wyboru odpowiedniego czasu interwencji oraz rolę intensywnej terapii. Szczegółowo omówiono dostępne terapie przezcewnikowe, w tym wystandaryzowane protokoły, definicje sukcesu i niepowodzenia procedury. Niniejszy dokument został opracowany we współpracy z ekspertami z różnych polskich towarzystw naukowych, co podkreśla rolę pracy zespołowej w opiece nad chorym z ostrą zatorowością płucną

Role of extended histological examination in the assessment of local recurrence of tongue and floor of the mouth cancer

AimThe aim is to find out why the rate of recurrence of tongue and floor of the mouth cancer is so high despite radical surgical treatment combined with radiochemotherapy.BackgroundOropharyngeal cancer is the second most common head and neck cancer in Poland. Tongue cancers account for 40% of all oral cavity tumours. A frequent reason for a failure in treatment of tongue and floor of the mouth cancers is local recurrence. Based on that examination, cancer treatment can be precisely planned.Materials and methodsThe study comprised a group of 56 tongue and floor of the mouth cancer patients. 9 patients who showed local recurrence were given an extended histopathological examination. The infiltration of the vessels, nerves and muscles was examined. The examination also checked the largest dimension of the tumour, the greatest depth of invasion from the mucous membrane, invasive front of the cancer, vessel embolisms, intra- and perineural infiltrations in the cancer invasive front. Tumour aggressiveness was assessed according to M. Brandwein-Gensler.ResultsIn five patients, primary tumours were found to be histologically aggressive as indicated by the infiltration of the vessels, nerves and muscles. Tumours which penetrate these structures were characterized with peri- and intraneural infiltration and were correlated with the depth of invasion from the mucous membrane, the occurrence of embolisms, and a high risk assessment as proposed by M. Brandwein-Gensler.ConclusionThe progression of cancer depends strongly on histopathological traits. The incidence of penetration of the vessels, nerves and muscles correlates with aggressiveness of the tumour front

Post-Effort Changes in Autophagy- and Inflammation-Related Gene Expression in White Blood Cells of Healthy Young Men

Acute, strenuous physical exertion requiring high levels of energy production induces the production of reactive oxygen species and metabolic disturbances that can damage the mitochondria. Thus, selective autophagic elimination of defective mitochondria may improve resistance to oxidative stress and potentially to inflammation. The main goal of this study was to evaluate the impacts of intense effort on changes in the expression of select genes related to post-effort inflammation and autophagy. Thirty-five men aged 16–21 years were recruited to the study. The impacts of both aerobic (endurance) and anaerobic (speed) efforts on selected genes encoding chemokines (CXCL5, 8–12) were analyzed. Significant increases in the expression of all studied genes excluding CXCL12 were observed. Moreover, both types of effort induced an increase in the expression of genes encoding IL-2, -4, -6, -10, IFN-γ and TNF-α, excluding IL-17A. Generally, these efforts caused a significant increase in the relative expression of apoptosis- (BCL2 and BAX) and autophagy- (BNIP3, BECN1, MAP1LC3B, ATG5, ATG7, ATG12, ATG16L1 and SQSTM1) related genes. It seems that the duration of physical activity and its bioenergetic cost has an important impact on the degree of increase in expression of this panel of autophagy-related genes. Anaerobic effort is more strenuous than aerobic effort and requires a higher bioenergetic investment. This may explain the stronger impact of anaerobic effort on the expression of the studied genes. This observation seems to support the protective role of autophagy proposed in prior studies

Her-2/neu ihc expression was measured in 114 primary invasive breast carcinomas by the manual and the automated scoring (ACIS and Aperio system). 106 slides stained ihc with two types of anti-ER/anti-PR antibodies entered the quantisation. The results of our investigations showed very high reproducibility of Her-2/neu scores in intra- and interobserver analysis by ACIS evaluation. The major concordance was present in strong 3+ ihc cases; very small discordance was shown by cases with low expression of Her-2/neu. The accuracy of scoring by the Aperio was little lower in comparison to ACIS but it might result from the smaller and variable series of samples analysed by Aperio. The concordance in scoring of two automated systems was 86.5% (p<0.0001; gamma=0.887); the discordance was referred only to the lower expression of Her-2/neu. The concordance in manual scoring performed by the single observer and the panel was 84.2% (p<0.0001, gamma = 0.99); the discordance comprised a few cases with strong expression (2+ vs 3+). Very high intra- and interobserver reproducibility of the ER/PR ihc measurements was present in the readers results (referred to the percentage of immunoreactive carcinomatous cell population in the breast carcinomas acc. to the ACIS algorithm). No differences were disclosed in the percentage of ER-immunoreactive and PR-immunoreactive carcinomatous cell populations when used 2 different type of antibodies, in the ACIS automated method
