The use of CA125, human epididymis protein 4 (HE4), risk of ovarian malignancy algorithm (ROMA), risk of malignancy index (RMI) and subjective assessment (SA) in preoperative diagnosing of ovarian tumors.

OBJECTIVES: To compare utility of CA125, human epididymis protein 4 (HE4), risk of ovarian malignancy algorithm (ROMA), risk of malignancy index (RMI) and subjective assessment (SA) in preoperative diagnosis of ovarian tumors. MATERIAL AND METHODS: Research was conducted among 456 patients qualified for surgery due to ovarian tumor. Preoperatively, CA125 and HE4 serum levels were estimated, and transvaginal ultrasound was performed. ROMA and RMI values and SA qualifications were obtained. Results were compared with pathomorphological findings. RESULTS: Receiver Operating Characteristic (ROC)-Area Under Curve (AUC) values for CA125, HE4, ROMA, RMI and SA in preoperative diagnosis of malignant lesions were 0.819, 0.909, 0.911, 0.895 and 0.895, respectively. Combinations of biochemical and sonographic methods increased sensitivity in diagnosis of ovarian tumors. Combinations utilizing serum HE4 concentrations were most useful. CONCLUSIONS: CA125, HE4, ROMA, RMI and SA proved to be useful in preoperative diagnosis of ovarian tumors. HE4 and ROMA occurred to be the most useful. Ultrasonographic methods are considerably useful in diagnosis of ovarian tumors. RMI and SA present similar overall diagnostic value.

Chemokine expression in patients with ovarian cancer or benign ovarian tumors.

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.

An Analysis of ESR2 and CYP19A1 Gene Expression Levels in Women With Endometriosis.

AIM: The analysis of oestrogen receptor (ESR2) and cytochrome P450 family 19 subfamily A member (CYP19A1) gene expression in the context of the risk for endometriosis development. MATERIALS AND METHODS: Tissue specimens, collected from patients with endometriosis (n=100) and from control patients (n=100) embedded into paraffin blocks, provided the material for genetic studies, oriented towards the expression of ESR2 and CYP19A1 genes. The gene expression was assessed by the reverse transcription-polymerase chain reaction technique. RESULTS: Higher expression levels of ESR2 gene were demonstrated in the patients with endometriosis in comparison with the healthy controls. The expression intensity of CYP19A1 gene was associated with endometriosis, manifested as abdominal wall nodules. A relationship was observed between CYP19A1 gene expression and the Revised American Society for Reproductive Medicine classification in the group with ovarian endometrioid cysts, as well as in the group with peritoneal endometriosis. CONCLUSION: This study suggests the significant role of ESR2 and CYP19A1 gene expression in the pathogenesis of endometriosis.

Analysis of the results of invasive diagnostic procedures in patients referred to gynecologic department due to abnormal uterine bleeding.

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.

Evaluation of adnexal tumours in the International Ovarian Tumor Analysis system in reference to histopathological results.

AIM OF THE STUDY: To retrospectively evaluate how the International Ovarian Tumor Analysis (IOTA) simple rules used in ultrasound examinations estimate the probability of malignant and benign tumour occurrence in the studied population. MATERIAL AND METHODS: The study was performed on a group of 425 patients with ovarian tumours operated in the Clinic of Surgical and Oncological Gynecology at the Medical University of Lodz in the years 2014-2015. Adnexal tumours were rated according to IOTA simple rules, classifying them as probably malignant, probably benign, or unclassified. The results of the study were compared with final histopathological results. The statistical analysis was performed using STATISTICA 13 PL with Medical Pack. RESULTS: We analysed data on n = 43 (11%) patients with malignant, n = 346 (86%) patients with benign, and n = 12 (3%) patients with borderline tumours, respectively. Malignant tumour patients were significantly older (mean age 61.0 ±11.6 vs. 43.6 ±16.2 years, p< 0.001), had higher BMI (mean 27.3 ±7.0 vs. 25.2 ±5.2, p< 0.05), more pregnancies (median 2 vs. 1, p = 0.001), and higher cancer antigen 125 (CA 125) concentrations (median 251.5 vs. 18.5, p< 0.001) than patients with a benign tumour. Also, they more often suffered from diabetes mellitus (19% vs. 8%, p = 0.02) and arterial hypertension (60% vs. 42%, p< 0.01) than benign tumour patients. CONCLUSIONS: In our study, IOTA performance in predicting or ruling out a malignant tumour was highly satisfactory and similar to that of CA 125. Both the methods may be complementary and used to assess the risk of malignant vs. benign ovarian neoplasm, although the context of other clinical variables may also be important.
