CA-125 concentration in serum and peritoneal fluid in patients with endometriosis - preliminary results

Introduction Cancer antigen 125 (CA-125), known as a biomarker for women genital tract malignancies, could be also useful in detecting and monitoring endometriosis. The aim of this study was to evaluate CA-125 in serum and peritoneal fluid (PF) as an indicator of endometriosis. Material and methods Fifty-six patients admitted to the First Department of Obstetrics and Gynaecology for diagnostic or therapeutic laparoscopy conducted for infertility, pelvic pain, suspected endometriosis or ovarian cysts entered the study. Those with laparoscopically confirmed endometriosis were assigned to group A, those without this condition to group B. Blood for CA-125 was taken prior to surgery, centrifuged and assayed in accordance with the manufacturers instructions (VIDAS CA-125 II). Peritoneal fluid and an endometrial biopsy were taken during laparoscopy. Statistical comparisons were performed using Statistica 7.1. Results Group A consisted of 44 women with laparoscopically confirmed diagnosis; 15 patients served as a control group. The mean value of CA-125 concentration in the endometriosis group was 33.98 U/ml, vs. 9.3 U/ml in the control group. The mean value of CA-125 in peritoneal fluid was 1241.88 U/ml in the non-endometriosis group versus 2640.23 U/ml in the study group; both results were statistically significant (p < 0.05). There was a significant correlation between the stage of endometriosis and CA-125 plasma concentration (R = 0.5993, p < 0.001). Cancer antigen 125 concentration in serum was a moderate predictor to distinguish between patients with and without endometriosis (AUC 0.794; 95% CI 0.668-0.921; p = 0.001). Conclusions Cancer antigen 125 is a well-known biomarker for endometriosis and helpful in daily clinical practice when endometriosis is suspected. The cut-off value in serum suggesting endometriosis with 68% sensitivity is 11 U/ml. This value is normal range for Ca-125 concentration.

Evaluation of selected angiogenic and inflammatory markers in endometriosis before and after danazol treatment.

Angiogenesis and inflammation are pivotal processes in developing endometriosis in the peritoneal cavity. The aim of the present study was to evaluate these two processes in women with endometriosis who had been treated with danazol to determine the sensitivity of a non-invasive test in diagnosing endometriosis. The clinical follow-up study was conducted in a group of 103 women diagnosed laparoscopically with endometriosis. Thirty-five patients qualified for danazol treatment. Pain was assessed using a visual analogue scale, whereas endometriosis was assessed using the revised American Society of Reproductive Medicine (rASRM) scale. Cancer antigen (CA)-125 and C-reactive protein (CRP) concentrations in plasma and peritoneal fluid were determined by immunoenzymatic methods, whereas vascular endothelial growth factor (VEGF) and interleukin (IL)-1β concentrations in plasma and peritoneal fluid were determined by ELISA. Endometrial expression of IL-8 and platelet-derived growth factor alpha polypeptide (PDGF-A) was determined using real-time polymerase chain reaction (PCR). Women with endometriosis (68.9% of patients) had higher plasma concentrations of CA-125, as well as higher concentrations of both CA-125 and VEGF in the peritoneal fluid. Endometrial expression of IL-8 mRNA was significantly higher, whereas that of PDGF-A was significantly lower, in contrast. After danazol treatment the patients reported lower pain scores; in addition, CA-125 concentrations in the plasma were decreased (P<0.001), whereas VEGF concentration in the plasma increased (P=0.009). For the diagnosis of endometriosis, none of the combinations of given markers had a sensitivity >60%. Danazol treatment is highly effective in relieving pain and decreasing CA-125 concentrations in the plasma. Higher plasma concentrations of VEGF after treatment could imply stimulation of angiogenesis.

Conservative treatment of deep infiltrating endometriosis: review of existing options

Abstract Endometriosis with its estimated incidence rate of ∼7–10% of women of reproductive age is a disease with the wide spectrum of symptoms depending on form and localization of endometrial foci. One clinical form of endometriosis is deep infiltrating endometriosis (DIE), most difficult to manage and generating a lot of direct and indirect treatment costs. We search the literature from PubMed database to establish the role of conservative treatment of DIE. Randomised controlled trials are lacking but in experts opinion hormonal treatment should be the first-line treatment in DIE. After evaluation of pain or other symptoms, second-line therapy with GnRH analogs or danazol should be offered or minimally invasive surgery. Consensus is not made whether surgery is the best therapeutic treatment for affected patients. Strong depending on surgeon’s experience conservative surgery should be offered if the total excision of DIE foci is possible, which is essential for a successful outcome. If available treatment options do not release pain associated with DIE, experimental treatment in clinical trials should be discussed with patients.

Clear cell ovarian cancer and endometriosis: is there a relationship?

Introduction Ovarian clear cell carcinoma is a rare type of ovarian cancer. In recent years, issues of the common genetic origin of endometriosis and ovarian clear cell carcinoma have been raised. Aim of this study Aim of this study was to evaluate the prevalence of this type of cancer, risk factors, prognosis and its potential aetiological association with endometriosis. Material and methods In a retrospective study, we analysed histopathological data of patients operated in the First Department of Gynaecology and Obstetrics (MU, Lodz) due to ovarian cancer in 2004-2014. Among the 394 patients operated on for ovarian cancer, clear cell carcinoma was found in 0.02% (9/394). Menstrual history, parity, comorbidities, data from physical examination, operational protocols and histopathological diagnoses were analysed. Follow-up was obtained from 77.8% of patients. Statistical analysis was performed using Microsoft Excel 2013. Results The mean age of patients at diagnosis was 57.6 years; the BMI in the study group was 27.2; the majority of patients were multiparous (77.8%). Clear cell carcinoma was detected mostly at stage Ia (n = 4). The concentration of Ca125 in the study group had an average of 142.75 U/ml and a median of 69.3 U/ml. The coexistence of endometriosis could not be clinically or histologically confirmed amongst our patients. The most common comorbidity in the study group was hypertension. Conclusions In our clinical material, ovarian clear cell carcinoma is a rare histopathological specimen with a prognostic value comparable to that of serous ovarian cancer. Due to the rarity of this histopathological subtype, proving a cause-and-effect relationship between it and endometriosis can only be elucidated through statistical studies of the entire population.
