Ekspresja caveoliny-1 w tkance okołoguzowej jest związana ze stopniem zróżnicowania histopatologicznego w surowiczych guzach jajnika

Background: Previous studies have demonstrated that Caveolin-1 (Cav-1) can ambiguously behave as tumor suppressor or tumor promoter in different neoplasms, depending on cancer type. Some findings have also revealed that cell proliferation, migration and invasion were attenuated by the knockdown of Caveolin-1 expressions. However, the functional and prognostic significance of Caveolin-1 in most tumors remains to be fully elucidated. Objectives: The aim of the study was to investigate a possible association between tissue Caveolin-1 expression and the clinicopathologic features of ovarian serous tumors. Material and methods: Caveolin-1 expression was studied in a total of 82 formalin-fixed, paraffin-embedded specimens of ovarian serous tumors and its association with different clinicopathologic parameters was evaluated. Results: The study included 36 (43.9%) benign, 12 (14.6%) borderline and 34 (41.5%) malignant serous tumors. Mean patient age was 43.9±14.4 years (17-72 years). Statistical analysis revealed that if the tumor becomes more aggressive and invasive, it losses the stromal Caveolin-1 expression (p=0.001). Also, parallel changes between stromal and perivascular Caveolin-1 expressions were observed. Conclusions: Our findings demonstrated a link between Caveolin-1 expression and the aggressiveness of ovarian cancer. Therefore, it seems safe to suggest that Cav-1 may act as a differential diagnostic biomarker in ovarian serous tumors.Wstęp: Wcześniejsze badania wykazały, że Caveolina-1 (Cav-1) może zachowywać się niejednoznacznie w zależności od rodzaju nowotworu, jako jego supresor lub promotor. Niektóre badania pokazały, że proliferacja komórek, migracja i inwazja były osłabiane przez obniżoną ekspresję Caveoliny-1. Jakkolwiek czynnościowe i prognostyczne znaczenie Caveoliny-1 w wielu guzach pozostaje w pełni do wyjaśnienia. Cel pracy: Celem badania była ocena możliwych związków pomiędzy ekspresją Caveoliny-1 i cechami klinicznopatologicznymi surowiczych guzów jajnika. Materiał i metoda: Ekspresję Caveoliny-1 oceniono w 82 tkankach surowiczych guzów jajnika utrwalonych w formalinie i zatopionych w parafinie i skorelowano z różnymi cechami kliniczno-patologicznymi. Wyniki: Do badania włączono 36 (43,9%) niezłośliwych, 12 (14,6%) granicznych i 34 (41,5%) złośliwych guzów surowiczych. Średnia wieku wynosiła 43,9±14,4 lat (17-72 lata). Analiza statystyczna wykazała, że im bardziej agresywny i inwazyjny był guz, tym bardziej tracił ekspresje Caveoliny-1 (p=0,001). Równolegle obserwowano zmiany ekspresji Caveoliny-1 w tkance łącznej i okołonaczyniowej. Wnioski: Nasze badania pokazują związek pomiędzy ekspresją Caveoliny-1 i złośliwością raka jajnika. Wydaje się, że Caveolina-1 może pełnić rolę biomarkera w diagnostyce różnicowej surowiczych guzów jajnika

Tissue expression of human epididymal secretory protein 4 may be useful in the differential diagnosis of uterine cervical tumors

Objectives: Human Epididymal Secretory Protein 4 was firstly described as an epididymis-specific protein but more recently it has been demonstrated to be a putative serum tumor marker for different malignancies, especially ovarian epithelial cancers. The aim of this study is to investigate the association between tissue Human Epididymal Secretory Protein 4 expression and the clinicopathological features of uterine cervical tumors. Material and methods: This retrospective study was designed to evaluate the differences of tissue expressions of Human Epididymal Secretory Protein 4 protein in a spectrum of cervical neoplasms. One hundred and seven patients recently diagnosed as having cervical intraepithelial neoplasm or invasive squamous cell carcinoma, adenosquamous carcinoma and adenocarcinoma based on pathology databases. Results: Decreased or negative Human Epididymal Secretory Protein 4 expressions were determined in both normal cervical epithelia and in intraepithelial carcinomas, while increased HE4 expression was observed in invasive tumors. Conclusions: This study demonstrated that altered expression of Human Epididymal Secretory Protein 4 may involve in tumorigenesis in the uterine cervix. Our findings also suggested the presence of a correlation between Human Epididymal Secretory Protein 4 expression and the invasive potential of uterine tumors. Therefore it may be thought that the tissue expression of HE4 can be used to differentiate high grade intraepithelial tumors from carcinomas

Diabetes Mellitus and Cancer

Diabetes and cancer are frequent diseases with important impact on human health all the world. Last epidemiologic studies suggests that patients with diabetes are at significantly higher risk for many forms of cancer. Type 2 diabetes and cancer share many risk factors. Increased insulin-like growth factor I (IGF-I) and reactive oxygen species can rol play in carcinogenesis. The systemic chronical inflammation which can result in a protumorigenic conditions. Hyperinsulinemia increases the risk of cancer in healthy people and it can partly explain obesity-cancer risk. The other point of view very important and difficult issue the medical treatment and dietary of diabetic patients with cancer

Renal "hyperfiltrators" are at elevated risk of death and chronic diseases

Background: The definition of glomerular hyperfiltration has not been agreed upon and the pathophysiological mechanisms have not been well explored. Low serum creatinine concentrations may be associated with increased risk of coronary heart disease (CHD) or cardiopulmonary events the impact of which needs further study

A Pitfall in Transrectal Prostate Biopsy: Malakoplakia Evaluation of Two Cases Based on the Literature Review

Malakoplakia is a rarely seen inflammatory condition that is considered to develop secondary to a chronic Escherichia coli infection. Although malakoplakia usually affects the genitourinary tract, it may also be observed in the colon, stomach, lungs, liver, bones, uterus, and skin. Malakoplakia of the genitourinary system usually involves the bladder, whereas it may also affect the prostate along with the bladder. Malakoplakia of the prostate is very rare, and it may be clinically mistaken for prostatic malignancies. Definitive diagnosis is only possible through histopathological examination. This study elaborates on two patients who presented to our hospital in 2013 with high PSA levels. The primary clinical consideration was prostate carcinoma. However, these two cases were diagnosed as malakoplakia based on the results of histopathological analysis of the transrectal prostate biopsy specimen

Preoperative Magnetic Resonance Volumetry in Predicting Myometrial Invasion, Lymphovascular Space Invasion, and Tumor Grade: Is It Valuable in International Federation of Gynecology and Obstetrics Stage I Endometrial Cancer?

WOS: 000431413200004Objective The aim of this retrospective single-center study was to evaluate the relationship between maximum tumor size, tumor volume, tumor volume ratio (TVR) based on preoperative magnetic resonance (MR) volumetry, and negative histological prognostic parameters (deep myometrial invasion [MI], lymphovascular space invasion, tumor histological grade, and subtype) in International Federation of Gynecology and Obstetrics stage I endometrial cancer. Methods/Materials Preoperative pelvic MR imaging studies of 68 women with surgical-pathologic diagnosis of International Federation of Gynecology and Obstetrics stage I endometrial cancer were reviewed for assessment of MR volumetry and qualitative assessment of MI. Volume of the tumor and uterus was measured with manual tracing of each section on sagittal T2-weighted images. Tumor volume ratio was calculated according to the following formula: TVR = (total tumor volume/total uterine volume) x 100. Receiver operating characteristics curve was performed to investigate a threshold for TVR associated with MI. The Mann-Whitney U test, Kruskal-Wallis test, and linear regression analysis were applied to evaluate possible differences between tumor size, tumor volume, TVR, and negative prognostic parameters. Results Receiver operating characteristics curve analysis of TVR for prediction of deep MI was statistically significant (P = 0.013). An optimal TVR threshold of 7.3% predicted deep myometrial invasion with 85.7% sensitivity, 46.8% specificity, 41.9% positive predictive value, and 88.0% negative predictive value. Receiver operating characteristics curve analyses of TVR, tumor size, and tumor volume for prediction of tumor histological grade or lymphovascular space invasion were not significant. The concordance between radiologic and pathologic assessment for MI was almost excellent ( value, 0.799; P < 0.001). Addition of TVR to standard radiologic assessment of deep MI increased the sensitivity from 90.5% to 95.2%. Conclusions Tumor volume ratio, based on preoperative MR volumetry, seems to predict deep MI independently in stage I endometrial cancer with insufficient sensitivity and specificity. Its value in clinical practice for risk stratification models in endometrial cancer has to be studied in larger cohort of patients
