ABSTRACT
OBJECTIVES: The present study aims to specify the role of L-carnitine in the pathogenesis of endometrial cancer by comparing the serum total L-carnitine levels of endometrial cancer patients with those of healthy women. METHODS: Serum total L-carnitine concentrations were measured in patients with endometrioid-type endometrial cancer (n = 20) and healthy controls (n = 20) who were matched with respect to age and body mass index (BMI). RESULTS: Stage I endometrial cancer was diagnosed in 12 women (60.0%) whereas three women (15.0%) had stage II disease, three women (15.0%) had stage III disease and two women (10.0%) had stage IV disease. The healthy controls and endometrial cancer patients were statistically similar in aspect of age, gravidity, parity, BMI, waist-to-thigh ratio, waist-to-hip ratio, menopause, complete blood count parameters, and serum biochemistry. Serum total L-carnitine levels of women with endometrial cancer were significantly lower than those of healthy women (respectively, 5,519.4 ± 2,712.5 vs 7,940.8 ± 3,566.6 ng/dl, p = 0.021). Moreover, serum total L-carnitine levels decreased significantly and progressively with advancing stage (stage I vs II vs III vs IV; 6,294.0 ± 2,885.1 vs 5,800.0 ± 441.2 vs 4,016.0 ± 2,833.3 vs 2,560.0 ± 67.9 ng/dl; p = 0.021). CONCLUSIONS: This is the first study to hypothesize that L-carnitine deficiency participates in the pathogenesis of endometrial cancer by means of a mechanism which is unrelated with obesity and increased amount of fat in human body.

AIM: The present study aims to determine whether mean platelet volume (MPV) specified in late first trimester of pregnancy can be used to predict pre-eclampsia and intrauterine growth restriction (IUGR). METHODS: This study prospectively reviews 200 healthy women with 11-14-week-old pregnancies. RESULTS: Average pregnancy-associated plasma protein-A (PAPP-A) multiples of the median (MoM) value was significantly lower and MPV was significantly higher in pre-eclamptic pregnancies (P = 0.001 for both). MPV values of 10.5 fl or more can predict pre-eclampsia with 66.7% sensitivity and 63.8% specificity. The combination of MPV of 10.5 fl or more and PAPP-A MoM of 0.33 or less can predict pre-eclampsia with 75% sensitivity and 70.0% specificity. MPV values of 10.5 fl or more can predict IUGR with 82.4% sensitivity and 60.0% specificity. The combination of MPV of 10.5 fl or more and PAPP-A MoM of 0.33 or less can predict IUGR with 85.3% sensitivity and 62.0% specificity. CONCLUSION: Increased MPV reflects enhanced platelet activation which may be caused by impairment in uteroplacental circulation. When MPV of 10.1 or more and PAPP-A MoM of 0.33 or less are combined as a threshold, the pregnancies that are destined to develop IUGR and pre-eclampsia can be predicted with considerably high sensitivity and specificity. The MPV and PAPP-A combination can be addressed as a useful biochemical tool for the prediction of IUGR and pre-eclampsia in late first trimester.

BACKGROUND: To evaluate the incidence, diagnosis and management of GTN among 28 centers in Turkey. MATERIALS AND METHODS: A retrospective study was designed to include GTN patients attending 28 centers in the 10-year period between January 2003 and May 2013. Demographical characteristics of the patients, histopathological diagnosis, the International Federation of Gynecology and Obstetrics (FIGO) anatomical and prognostic scores, use of single-agent and multi-agent chemotherapy, surgical interventions and prognosis were evaluated. RESULTS: From 2003-2013, there were 1,173,235 deliveries and 456 GTN cases at the 28 centers. The incidence was calculated to be 0.38 per 1,000 deliveries. According to the evaluated data of 364 patients, the median age at diagnosis was 31 years (range, 15-59 years). A histopathological diagnosis was present for 45.1% of the patients, and invasive mole, choriocarcinoma and PSTTs were diagnosed in 22.3% (n=81), 18.1% (n=66) and 4.7% (n=17) of the patients, respectively. Regarding final prognosis, 352 (96.7%) of the patients had remission, and 7 (1.9%) had persistence, whereas the disease was mortal for 5 (1.4%) of the patients. CONCLUSIONS: Because of the differences between countries, it is important to provide national registration systems and special clinics for the accurate diagnosis and treatment of GTN.
