BackgroundCopeptin, a surrogate marker for arginin vasopressin production, is evaluated as an osmo-dependent stress and inflammatory biomarker in different diseases. We investigated copeptin during the menstrual cycle and its relationship to sex hormones, markers of subclinical inflammation and estimates of body fluid.MethodsIn 15 healthy women with regular menstrual cycles, blood was drawn on fifteen defined days of their menstrual cycle and was assayed for copeptin, progesterone, estradiol, luteinizing hormone, high-sensitive C-reactive protein, tumor necrosis factor-alpha and procalcitonin. Symptoms of fluid retention were assessed on each visit, and bio impedance analysis was measured thrice to estimate body fluid changes. Mixed linear model analysis was performed to assess the changes of copeptin across the menstrual cycle and the relationship of sex hormones, markers of subclinical inflammation and estimates of body fluid with copeptin.ResultsCopeptin levels did not significantly change during the menstrual cycle (p = 0.16). Throughout the menstrual cycle, changes in estradiol (p = 0.002) and in the physical premenstrual symptom score (p = 0.01) were positively related to copeptin, but changes in other sex hormones, in markers of subclinical inflammation or in bio impedance analysis-estimated body fluid were not (all p = ns).ConclusionAlthough changes in estradiol and the physical premenstrual symptom score appear to be related to copeptin changes, copeptin does not significantly change during the menstrual cycle.
PurposeThe stage of disease is one of the strongest prognostic factors in epithelial ovarian cancer. The International Federation of Gynecology and Obstetrics (FIGO) classification was revised in 2013; stage IC was subdivided into IC1 (intraoperative surgical spill), IC2 (capsule rupture before surgery or tumor on surface), and IC3 (positive peritoneal washing or ascites). Our aim was to compare the outcome of patients in the new FIGO stage I subgroups, as this might influence adjuvant therapy decisions.Patients and methodsPatient databases of three gynecological oncology centers were retrospectively analyzed. Patients with FIGO stage I ovarian cancers were restaged according to the revised classification, based on operative and pathological reports, and determined patient outcomes.ResultsWe analyzed 128 patients with ovarian cancers. In FIGO IA, we found 11.3% recurrences and 4.2% deaths. In FIGO IC, 21.8% of the patients recurred and 7.3% died. There was a trend toward a shorter time to recurrence when comparing IA to IC (P=0.076). Within all new subgroups of FIGO IC, there was no difference in time to recurrence (P=0.59). There was also no significant difference in survival when FIGO IA was compared to FIGO IC in comparison with the new individual classifications (IA to IC, IA to IC1, 2, or 3; P=0.60, P=0.15, P=0.61, P=0.66, respectively) or within the different subgroups (P=0.56). Platinum-based chemotherapy was given to the majority (82.6%, n=38/46) of the FIGO IC patients compared to 30.9% in FIGO IA (n=17/55). There was no significant difference within the new subgroups of FIGO IC (P=0.88).ConclusionIn our retrospective analysis, the new FIGO staging of IC ovarian cancers did not predict prognosis, but the use of adjuvant chemotherapy in 82.6% of the stage IC patients may have biased the outcome.
Peritoneal biopsies (PB) and peritoneal washing (PW) are routine measures in abdominal staging of gynecological malignancies and are used particularly for the assessment of occult microscopic tumor spread to the peritoneal surface including the diaphragm. Cytological diaphragmatic smears (DS) have been suggested as a supplemental tool; however, they are not routinely taken and their usefulness is still unclear. The present study retrospectively evaluated whether DS provide an additional benefit over PB and PW for the detection of peritoneal malignancies in patients with gynecological cancer. The data from patients who underwent laparotomy for suspected gynecological cancer and had DS and either PB, PW or ascites were reviewed. Sensitivity and specificity, and the number upstaged patients were determined. A total of 43 patients were excluded due to benign diagnosis (those with negative DS or PW) and 2 out of the remaining had 2 carcinomas simultaneously. Among these 41 malignancies, DS were positive in 12, PW in 18 and PB in 19 cases. No case was DS-positive while negative for both PB and PW. Four cases were missed when only PB and 5 when only PW was performed. Notably, no case of peritoneal disease was identified solely on positive DS, indicating that all 23 positive cases (presence of occult peritoneal disease in 56.1%) were identified by PB and PW together (100% sensitivity; 62% specificity). In addition, none of the cases was upstaged solely on positive DS results. Taken together, these data demonstrated that DS do not present an additional benefit to PW and PB in the detection of peritoneal gynecological disease.
