RESUMEN

The coordinated action of VEGF, IGF1/2 and H19 factors influences the development of endometriosis. The aim of this study was to analyze the expression level of these genes in patients with endometriosis. The study group consisted of 100 patients who were diagnosed with endometriosis on laparoscopic and pathological examination. The control group consisted of 100 patients who were found to be free of endometriosis during the surgical procedure and whose eutopic endometrium wasnormal on histopathological examination. These patients were operated on for uterine fibroids. Gene expression was determined by RT-PCR. The expression of the VEGF gene was significantly higher in the samples classified as clinical stage 1-2 compared to the control material (p < 0.05). There was also a statistically significant difference between the samples studied at clinical stages 1-2 and 3-4 (p < 0.01). The expression of the VEGF gene in the group classified as 1-2 was significantly higher. IGF1 gene expression was significantly lower both in the group of samples classified as clinical stages 1-2 and 3-4 compared to the control group (p < 0.05 in both cases). The expression of the H19 gene was significantly lower in the group of samples classified as clinical stage 3-4 compared to the control group (p < 0.01). The reported studies suggest significant roles of VEGF, IGF and H19 expression in the pathogenesis of endometriosis.

RESUMEN

MicroRNAs (miRNAs) are short, noncoding, single-stranded RNA molecules that regulate gene expression at the post-transcriptional level by binding to mRNAs. miRNAs affect the course of processes of fundamental importance for the proper functioning of the organism. These processes include cell division, proliferation, differentiation, cell apoptosis and the formation of blood vessels. Altered expression of individual miRNAs has been shown in numerous cancers, which may indicate the oncogenic or suppressor potential of the molecules in question. This paper discusses the current knowledge about the possibility of using miRNA as a diagnostic marker and a potential target in modern anticancer therapies.

RESUMEN

Endometriosis is a disease of complex etiology. Hormonal, immunological, and environmental factors are involved in its formation. In recent years, special attention has been paid to genetic mechanisms that can have a significant impact on the increased incidence of endometriosis. The study aimed to analyze the expression of four long non-coding RNA (lncRNA) genes, UCA1, MALAT1, TC0101441, and H19, in the context of the risk of developing endometriosis. The material for genetic testing for the expression of lncRNA genes were tissue slices embedded in paraffin blocks from patients with endometriosis (n = 100) and the control group (n = 100). Gene expression was determined by the RT-PCR technique. The expression of the H19 gene in endometriosis patients was statistically significantly lower than in the control group. A statistically significant association was found between H19 gene expression in relation to The Revised American Society for Reproductive Medicine classification of endometriosis (rASRM) in the group of patients with endometriosis. Research suggests that H19 expression plays an important role in the pathogenesis of endometriosis.

RESUMEN

Endometriosis is a "mysterious" disease and its exact cause has not yet been established. Among the etiological factors, congenital, environmental, epigenetic, autoimmune and allergic factors are listed. It is believed that the primary mechanism of the formation of endometriosis foci is retrograde menstruation, i.e., the passage of menstrual blood through the fallopian tubes into the peritoneal cavity and implantation of exfoliated endometrial cells. However, since this mechanism is also observed in healthy women, other factors must also be involved in the formation of endometriosis foci. Endometriosis is in many women the cause of infertility, chronic pain and the deterioration of the quality of life. It also represents a significant financial burden on health systems. The article presents a review of the literature on endometriosis-a disease affecting women throughout the world.

RESUMEN

Endometriosis is defined as the presence of endometrial foci, localized beyond their primary site, i.e., the uterine cavity. The etiology of this disease is rather complex. Its development is supported by hormonal, immunological, and environmental factors. During recent years, particular attention has been focused on the genetic mechanisms that may be of particular significance for the increased incidence rates of endometriosis. According to most recent studies, ESR2 and CYP19A1 genes may account for the potential risk factors of infertility associated with endometriosis. The paper presents a thorough review of the latest reports and data concerning the genetic background of the risk for endometriosis development.

RESUMEN

INTRODUCTION: Abnormal uterine bleeding (AUB) is one of the most common reason for visits to gynecologists. Endometrial biopsy is a routine procedure in gynecological practice to detect the etiology of AUB and to exclude precancerous and cancerous lesions of the endometrium. The aim of this study was to assess the causes of AUB among women, who had undergone invasive diagnostics due to AUB. MATERIAL AND METHODS: This study was carried among 531 women, who had undergone invasive diagnostics due to AUB between January 2018 and December 2018. Women were divided into premenopausal (with perimenopausal) and postmenopausal groups. Transvaginal ultrasound was performed. Endometrial thickness was compared with histopathological results in each subgroup and statistically analyzed. The incidence of histopathological findings and rate of anemia were also analyzed. RESULTS: In our series of patients the most common cause of AUB based on histopathological results was endometrial polyp, both before and after menopause. The most frequent pathologies at ultrasound findings were leiomyomas and endometrial polyps. The incidence of taken together: atypical hyperplasia and endometrial cancer was significantly higher in postmenopausal group (8.58%) than in pre- and perimenopausal (1.35%, p = 0.0001). The median endometrial thickness, both before and after menopause, was significantly greater in patients with pathological than with nonpathological endometrium. 31% of women with abnormal uterine bleeding before menopause and 10% after menopause had anemia. CONCLUSIONS: Measurements of endometrial thickness seems to be acceptable initial diagnostic tool to distinguish between benign and pathological endometrial changes both before and after menopause.

RESUMEN

INTRODUCTION: Long-term infection with human papillomavirus (HPV) is the cause of cervical cancer and its precursor - cervical intraepithelial neoplasia (CIN). The presence of HPV infection can be presumed in more than 99% of cases of cervical cancer worldwide. The introduction of DNA testing for the presence of HPV has increased the effectiveness of screening programs for the detection of this cancer. This study aimed to analyze the prevalence of high risk HPV DNA (HR HPV) in females from Poland. MATERIAL AND METHODS: The study was performed on 280 cervical smear samples. In this work we used the Roche Cobas 4800 HPV test to detect the HR HPV in cervical smear samples. RESULTS: 56 patients (20%) proved to be positive regarding HPV-16 DNA and 40 patients (14.28%) regarding HPV-18 DNA. In overall assessment, in 94 patients (33.57%) we detected oncogenic HPV subtypes, other than the two mentioned above. In 90 patients (32.14%) no high risk HPV was detected. CONCLUSIONS: The Roche Cobas 4800 HPV test is a viable, effective, easy and quick tool in detecting high risk HPV DNA.

RESUMEN

Endometrial cancer is one of the most common cancers experienced by women throughout the world. It is also the most common malignancy within the female reproductive system, representing 37.7% of all disorders. The incidence increases with age, and is diagnosed most frequently in women between 45 and 65 years old. In the last few years, numerous studies have been performed to identify tumour biomarkers. Biomarkers include not only protein routinely used as tumour markers but also genes and chromosomes. The limiting factor in the use of markers in the diagnosis of endometrial cancer is their lack of specificity. However, specific markers for endometrial cancer are the subject of much research attention. Although moderately elevated levels of markers are present in a number of inflammatory or non-malignant diseases, significantly increased levels of markers indicate the development of cancer. Recently, research has been focused on the identification of molecular changes leading to different histological subtypes of endometrial cancer. In this paper the authors reviewed several currently investigated markers. Progress in these investigations is very important in the diagnostics and treatment of endometrial cancer. In particular, the identification of novel mutations and molecular profiles should enhance our ability to personalise adjuvant treatment with genome-guided targeted therapy.

RESUMEN

OBJECTIVES: Endometrioid and clear cell ovarian adenocarcinomas are suspected to derive from ectopic endometrial foci. The aim of the study was to determine PTEN and MMP-2 immunoexpression in endometrial ovarian cysts, endometrioid and clear cell ovarian carcinomas and to assess the relationship between the abovementioned values and clinical data of patients in order to find the marker of increased risk of malignant proliferation based on ovarian endometriotic lesions. Detailed analysis of the collected data was conducted to investigate the correlation between immunohistochemical expression of the examined antigens, histopathological diagnosis and clinical condition of patients. MATERIAL AND METHODS: 20 endometrial adenocarcinomas, 21 clear cell ovarian cancers and 26 endometrial cysts were included in the study The control group consisted of 29 specimens of physiological endometrium: 16 samples of the proliferative phase and 13 samples of the secretory phase. Protein expression of PTEN and MMP-2 was evaluated by immunohistochemistry Protein immunoexpression in the collected specimens was estimated with the use of light microscope and MultiScan software. Immunoreactivity of the PTEN antigen was assessed by the quantitative method, whereas MMP-2 immunoexpression was evaluated by the semi-quantitative method. Two-sided tests were used for statistical inference. Generalized linear models were used to compare the studied groups. Error distributions were selected using the Akaike criterion (AIC). Statistical analysis was conducted with the use of the R Statistical Package. RESULTS: MMP-2 immunoreactivity differed significantly between the study groups and controls (p<0.001). PTEN immunoexpression was the strongest in endometrial cysts (53.7 %), lower in clear cell cancers (50.2%) and the lowest in endometrioid adenocarcinomas (43.88%), but the differences were not statistically significant (p=0.17). PTEN reactivity in the group of endometrioid carcinomas was significantly higher (p=0.02), while MMP-2 expression had a falling tendency (p=0.076) in obese women. CONCLUSIONS: Increased MMP-2 expression in the successive groups may imply a rising invasive potential of the epithelial cells in endometrial cysts, endometrioid and clear cell adenocarcinomas. Strong immunoreactivity for PTEN in proliferative endometrium implies its role in the regulation of endometrial proliferation. PTEN activity may reduce MMP-2 expression in insulin resistant women suffering from endometrial ovarian cancer Simultaneous evaluation of PTEN and MMP-2 immunoexpression in ectopic endometrial foci cannot be used to identify women with an increased risk of neoplastic transformation.

RESUMEN

BACKGROUND: Endometriosis is a chronic disease of the genital organs that mainly affects women of reproductive age. The analysis of long non-coding RNA (lncRNA) in endometriosis is a novel field of science. Recently, attention has been drawn to SNHG4, which is incorrectly expressed in various human diseases, including endometriosis. AIM: The aim of this pilot study was to analyze the expression of lncRNA small nucleolar RNA host gene 4 (SNHG4) and to investigate its significance in endometriosis. MATERIAL AND METHODS: LncRNA SNHG4 expression was investigated in paraffin blocks in endometriosis patients (n = 100) and in endometriosis-free controls (n = 100) using a real-time PCR assay. RESULTS: This study revealed a higher expression of SNHG4 in endometriosis patients than in controls. A statistically significant relationship between expression level and SNHG4 was found in relation to The Revised American Society for Reproductive Medicine classification of endometriosis, 1996, in the group of patients with endometriosis. CONCLUSION: This pilot study has revealed that gene expression in SNHG4 plays an important role in the pathogenesis of endometriosis.

RESUMEN

Endometriosis is a disease of the female genital organs, the causes of which are not fully understood. Recent studies have shown that non-coding RNAs (ncRNAs) like long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) can contribute to the pathogenesis of endometriosis. Profiling of miRNA and lncRNA expression is carried out using state-of-the-art molecular biology techniques (RT-PCR, sequencing, microarray analysis). The use of the latest technologies may make it possible to establish a genetic profile, which is a promising prospect for early diagnosis of endometriosis. In the future, genetic testing may become the gold diagnostic standard and eliminate invasive laparoscopy. In the case of endometriosis, it is important to extend the research to molecular aspects, which may facilitate the diagnosis of the disease or indicate new (based for example ncRNA) treatment methods. The paper presents the latest data on the importance of miRNA/lncRNA in endometriosis.

RESUMEN

Significant relationships with endometrial cancer were demonstrated, both for CCL2, CCL5, and CXCL8 chemokines and for the chemokine receptor CXCR2. The reported case-control study of genetic associations was designed to establish the role of selected single nucleotide polymorphisms (SNPs) of the CCL2, CCL5, CXCL8, and CXCR2 genes in the onset and progression of endometrial cancer. This study was conducted on 282 women, including 132 (46.8%) patients with endometrial cancer and 150 (53.2%) non-cancerous controls. The genotypes for CCL2 rs4586, CCL5 rs2107538 and rs2280789, CXCL8 rs2227532 and -738 T>A, and CXCR2 rs1126580 were determined, using PCR-RFLP assays. The AA homozygotes in CCL5 rs2107538 were associated with more than a quadruple risk of endometrial cancer (p ≤ 0.050). The GA heterozygotes in the CXCR2 SNP were associated with approximately threefold higher cancer risk (p ≤ 0.001). That association also remained significant after certain adjustments, carried out for age, diabetes mellitus, arterial hypertension, or endometrial thickness above 5 mm (p ≤ 0.050). The A-A haplotypes for the CCL5 polymorphisms and T-A-A haplotypes for the CCL2 and CCL5 SNPs were associated with about a twofold risk of endometrial cancer (p ≤ 0.050). In conclusion, CCL2 rs4586, CCL5 rs2107538 and rs2280789, and CXCR2 rs1126580 demonstrated significant associations with an increased risk of endometrial cancer.

RESUMEN

Deep infiltrating endometriosis (DIE) is characterized by the presence of endometrial tissue outside the uterine cavity that infiltrates at least 5-mm deep below the peritoneal layer. Imagining examinations are the first-choice methods to detect DIE. The aim of this study is to assess whether rectal water contrast transvaginal sonography (RWC-TVS) can be a useful tool for the estimation of the size of deep bowel endometriotic nodules. This retrospective study includes 31 patients subjected to RWC-TVS who underwent surgery due to deep bowel endometriosis between January 2021 and December 2022. Nodule dimensions measured via ultrasound were compared to those of histopathological samples taken after surgery. In total, 52% of patients had endometriosis limited only to the intestines, 19% had endometriotic nodules located at uterosacral ligaments and posterior vaginal fornix, 6% at the anterior compartment, and 13% at a different location. Additionally, 6% of patients had nodules at more than two locations. In all but one case, the intestinal nodules could be seen on RWC-TVS images. The largest nodule dimension measured via RWC-TVS and the size of the equivalent histopathological sample correlated (R = 0.406, p = 0.03). Thus, RWC-TVS allows for the detection of DIE and moderate estimation of the nodule sizes and should be practiced during a diagnostic process.

RESUMEN

Endometriosis is defined by endometrial glands and stroma outside of the endometrial cavity Three types of endometriosis have been described: peritoneal endometriosis, ovarian endometriosis and deep infiltrating endometriosis. Endometriosis afflicts 6-15% of women population. It occurs mainly in the group of women in reproductive age, but also in the group of minors and approximately 3% of women after menopause. Within the group of women suffering from infertility the frequency of endometriosis increased to 35-50% of cases. Endometriosis is associated with pain symptoms which can bear the character of pain occurring periodically and altering into constant pain, dysmenorrhea, dyspareunia, dysuria and dyschezia. The correlation between the stage of endometriosis and intensity of pain symptoms not always has to be proportionate. Laparoscopy can be perceived as a standard procedure in endometriosis diagnostics as it allows simultaneous treatment. Profound interview as well as visual diagnostics (USG, MRI) should precede laparoscopy Treatment of endometriosis can be divided into pharmacological and surgical treatment, which can be invasive or non-invasive. The type of treatment depends on patient's age and her procreation plans, occurring ailments and endometriosis type. Important role is played by adjuvant treatment such as appropriate diet and lifestyle. Treatment of advanced endometriosis should be conducted in reference centres that are appointed with adequate equipment and have the possibility of interdisciplinary treatment. Presented standards can digest and outline the order of proceedings both in diagnostics and endometriosis treatment. The research group believes that the above compilation will facilitate undertaking appropriate decision in diagnosis and treatment of the disease, which will subsequently contribute to therapeutic success.

RESUMEN

Endometriosis is a common gynaecological disease of unknown etiology. Angiogenesis appears to be one of the processes involved in its pathogenesis. Angiogenic factors VEGF level is increased in patients with endometriosis. Studies have shown that endometriosis maybe associated with VEGF single nucleotide polymorphism (SNP) polymorphisms. Results from studies that assayed VEGF polymorphism in endometriosis are reviewed. Data in the literature suggest that VEGF SNPs such as: -460C/T +405G/C and 936C/T seem to be a risk factor for endometriosis.

RESUMEN

Introduction: Chemokines play a crucial role in tumor growth and progression according to proangiogenic and immunosuppressive action. The aim of this study was to investigate the serum levels of selected chemokines in patients with ovarian cancer or benign ovarian tumors to assess their role in tumorigenesis and their potential use in preoperative diagnosis of an adnexal mass. Material and methods: The study group consisted of 59 women with ovarian cancer: 17 epithelial ovarian cancer (EOC) patients and 42 women with benign ovarian tumors. We measured in sera obtained preoperatively the level of CA125 and a panel of 5 chemokines - CX3CL1/fractalkine, CXCL1/GRO-α, CXCL12/SDF-1, CCL20/MIP-3α and IL-17F - using the chemiluminescence method with multiplexed bead based immunoassay. Results: CX3CL1 was significantly elevated in sera of advanced ovarian cancer patients compared to women with benign ovarian tumors. The significant elevation of CXCL1 was also observed (both early and advanced stages). A similar pattern was present with the standard ovarian cancer marker CA125. In our patients with endometriotic cysts CA125 levels were significantly higher than in women with other benign tumors, whereas all analyzed chemokines had similar serum titers in patients with endometriotic vs. other benign ovarian cysts. Conclusions: CX3CL1 and CXCL1 are elevated in sera of EOC patients, which indicates their role in cancer development. Moreover, they might be useful in preoperative differential diagnosis of ovarian tumors, especially as they were not elevated in cases of endometriosis.

RESUMEN

BACKGROUND: Polymorphisms in the human oxoguanine glycosylase 1 ( hOGG1 ) and X-ray repair cross-complementing 1 ( XRCC1 ) genes have been extensively studied in the association with various human cancers such as endometrial cancer. MATERIAL AND METHODS: The genotype analysis of hOGG1 Ser326Cys and XRCC1 Arg399Gln gene polymorphisms for 150 endometrial cancer patients and 150 controls of cancer-free subjects, in the Polish population, were performed using PCR-based restriction fragment length polymorphism (PCR-RFLP). RESULTS: Although there were no significant (p > 0.05) differences in the frequencies of genotypes or alleles of hOGG1 genes between patients and controls, the frequency of the XRCC1 399Gln allele was significantly greater in endometrial cancer patients compared with controls (p = 0.033) with an odds ratio of 1.39 (95% confidence interval 0.99 to 1.95). The distributions of genotypes and alleles of the genes hOGG1 and XRCC1 were not significantly associated with different grades of endometrial cancer (p > 0.05). CONCLUSION: In conclusion, these findings indicated that XRCC1 Arg399Gln polymorphism may be a genetic determinant for developing endometrial cancer. The hOGG1 Ser326Cys may not play an important role in susceptibility to endometrial cancer in Polish women.

RESUMEN

BACKGROUND: Despite advanced diagnostic and therapeutic procedures, endometrial cancer (EC) is still responsible for high morbidity and mortality of women. The genetic variability in RAD51 may contribute to the appearance and progression of various cancers including EC. AIM: We investigated the association of polymorphisms in the DNA repair genes RAD51 135G>C and 172G>T with endometrial cancer risk. MATERIAL AND METHODS: The genotypes of RAD51 135G>C and 172G>T polymorphism were determined by PCR-RFLP methods in endometrial tissue of 240 cancer subjects and 240 healthy subjects who served as controls. RESULTS: In the present work we demonstrated a significant positive association between the RAD51 C/C genotype and endometrial carcinoma, with an adjusted odds ratio (OR) of 13.0 (p < 0.0001). The distribution of genotypes for 135G>C SNP in endometrial cancer patients vs. controls was: 10% vs. 27% for GG, 13% vs. 58% for GC and 77% vs. 15% for CC genotype, respectively. Variant 135C allele of RAD51 increased the cancer risk (OR = 1.81; 95% CI 0.11-2.93, p = 0.022). The higher risk of EC occurrence was associated with the combined C135C-G172T genotype (OR = 7.69; 95% CI 3.45-17.12). CONCLUSION: The results indicated that the polymorphism 135G>C of the RAD51 gene may be positively associated with endometrial carcinoma in the Polish population. Further studies, conducted on a larger group, are required to clarify this point.

RESUMEN

OBJECTIVE: To analyze the profiles of interleukin-2 (IL-2), IL-6, IL-8, IL-10, tumor necrosis factor-alpha (TNF-alpha), transforming growth factor-beta1 (TGF-beta1) and interferon-gamma (IFN-gamma) in serum and the tumor microenvironment (cyst fluid, ascites) in women with ovarian cancer or benign ovarian tumors to find the differences in their immunological status. We also estimated serum cytokines as biomarkers to distinguish preoperatively between malignant or benign character of tumors. DESIGN: Prospective study. SETTING: Tertiary referral hospital. POPULATION: 51 women with epithelial ovarian cancer, 26 with benign ovarian tumors of epithelial origin and 21 healthy controls. METHODS: The levels of cytokines were measured using ELISA sets. RESULTS: We did not found differences in the levels of IFN-gamma, TNF-alpha and IL-2 in all fluids isolated from patients with malignant or benign tumors. Women with advanced cancer had significantly higher serum IL-6, IL-10 and TGF-beta1 levels than women with early stages or benign tumors. Moreover, women with very advanced cancer in whom the optimal cytoreduction was disabled had the highest serum levels of IL-10, TGF-beta1 and IL-8. The concentrations of IL-6 and IL-8 were higher in ascites of cancer patients than in ascites of women with benign tumors. The areas under curves constructed for the selected cutoff serum cytokines levels (AUC-ROC) showed good predictive values for IL-6 (0.87), IL-10 (0.836) and IL-8 (0.797). CONCLUSIONS: Our results indicate on intensified inflammatory process in women with ovarian cancer (accompanied by their immunosuppression).

RESUMEN

INTRODUCTION: Cervical Cancer Screening Program has been operational in Poland for over four years. Colposcopy and guided biopsy methods constitute an essential part of population-based screening, enable stating right diagnosis and planning treatment procedures. AIM: The aim of the following study was to analyse the diagnostic acuity of cyto- and histopathological examination. RESULTS: We examined 510 patients with the following result of cytological smear: ASCUS--265 women (51.96%), LSIL--167 cases (35.75%), HSIL--78 women (15.29%). Complete agreement between cytological smear and guided biopsy histopathology was observed among 81.13% cases of ASCUS, in 88.02% of women with LSIL and in 76.92% cases with the diagnosis of HSIL. As with cytology-biopsy comparisons, discordant cases were significantly more frequent in the group with stated HSIL than among patients with the diagnosis of ASCUS or LSIL (p<0.001). CONCLUSIONS: 1. High cyto-histopathological accordance (82%) has been obtained, what is comparable with the data in literature. 2. The highest cyto- histopathological compatibility was obtained in the group of patients with LSIL--over 88%, and the lowest in the group of patients with HSIL--less than 77%. 3. Failure to confirm the histopathological diagnosis of cytological HSIL requires further molecular and morphological evaluation.
