Problem: Studies have shown a relationship between endometriosis and ovarian cancer. Our aims were to evaluate and compare the dosages of cytokines IL-2, IL-5, IL-6, IL-8, IL-10, and TNF-α in serum, intracystic fluid, and peritoneal fluid of patients with ovarian endometrioma, malignant and benign ovarian neoplasms, and non-neoplastic ovarian tumors; to verify if there is a correlation between the values of these cytokines between ovarian endometrioma and ovarian malignancy; and to determine the best cut-off point for serum cytokines that can be used to differentiate patients with ovarian malignancy and endometrioma.

Method Of Study: The concentrations of cytokines were quantified by enzyme-linked immunosorbent assay (ELISA), analyzed by Kruskal-Wallis test with the Dunn post-test.

Purpose: The aim was to investigate the systemic levels of cytokines and the expression of the chemokine receptor CXCR2 in circulating neutrophils in patients with non-neoplastic ovarian lesions, benign neoplasia or malignant neoplasia.

Materials And Methods: Controls and patients with ovarian tumours were pre-operatively compared for the production of cytokines (IL-2, IL-5, IL-6, IL-8, IL-10 and TNF-α) by ELISA, and for the expression of the chemokine receptor, CXCR2, in neutrophils, by flow cytometry. Randomly selected patients within the malignant group were re-evaluated for the inflammatory parameters at 30 days after surgery.

The objectives of the study were to analyze the dosage of a cytokine panel (IL2, IL5, IL6, IL8, IL10, and TNF-α) in the peritoneal fluid and relate the dosage of these cytokines to prognostic para- meters and survival in ovarian cancer. Peritoneal fluid was collected intraopera- tively from 29 patients with primary malignant ovarian neoplasia. Cytokine panel dosing was performed with ELISA.

The aim of this study was to evaluate cytokine levels (IL-2, IL-8, TNF-α, IL-5, IL-6 and IL-10) in the peritoneal fluid in non-neoplastic tumours, benign ovarian neoplasms and malignant ovarian neoplasms. Peritoneal fluid or ascites was collected from 117 patients with neoplastic and non-neoplastic ovarian tumours. Cytokine levels were assessed by ELISA.

The aims of the study were to compare the levels of tumor necrosis factor alpha (TNF-α) and its soluble type I (sTNF-R1) and type II (sTNF-R2) receptors detected in intracystic liquid and serum from benign and malignant ovarian neoplasms and to relate them to prognostic factors in epithelial ovarian cancer. The patients were divided into benign ovarian neoplasms (n = 46) and malignant ovarian neoplasms (n = 17). The serum and intracystic samples were collected before and during surgery for ovarian cyst, respectively.

The aim of the study was to correlate serum levels of IL-2, IL-5, IL-6, IL-8, IL-10, and TNF-α with clinical, laboratory, and pathological prognostic factors in patients with primary ovarian malignancy. Patients treated at the Pelvic Mass Ambulatory of the Discipline of Gynecology and Obstetrics/Oncology Research Institute (IPON) of the UFTM with confirmed diagnosis of malignant ovarian neoplasia (n = 26) were evaluated. Serum collection was performed preoperatively for the determination of tumor markers.

Objective: To characterize the inflammatory profiles of patients with systemic lupus erythematosus receiving standard treatment compared to healthy controls.

Patients And Methods: Peripheral venous blood was collected from systemic lupus erythematosus patients (n=14) and controls (n=18) at enrollment. Blood samples were used for quantification, by flow cytometry, of CD11b (integrin) and Chemokine receptor CXCR2 expression surface antigen in neutrophils and lymphocytes, while cytokines were assayed in serum samples.

Aim: To verify if patients with cervical neoplasia produce mediators that reduce leukocyte function.

Methods: Control neutrophils incubated with normal serum or serum from pre-invasive or invasive neoplasia patients were assayed for chemotaxis. Mediators were assayed in serum and in leukocyte supernatants.

Aims And Background: Our aim was to evaluate the effect of treatment on the in vitro migration of circulating mononuclear cells in cervical cancer patients at different stages.

Methods: We prospectively investigated 24 patients with cervical neoplasia, without prior treatment, submitted to surgery or chemotherapy as therapeutic conduct. Controls were healthy volunteer women (n = 23).
