Fetal gender has a significant effect on maternal and cord blood hCG levels, particularly during the last trimester of the pregnancy. However, the reason for this difference is obscure. The aim of the present study was to investigate whether term fetal hypophyseal - adrenal - gonadal axis differs between female and male fetuses thereby causing different hCG levels. The study consisted of 60 women with singleton pregnancies in the third trimester. Thirty-one pregnant women were carrying female fetuses, whereas 29 were carrying male. Human chorionic gonadotropin (hCG), estradiol, progesterone, testosterone, dehydro-epiandrosteron-sulfate (DHEAS), prolactin and growth hormone levels were measured in maternal serum and umbilical cord blood. In female bearing pregnancies maternal and cord blood hCG levels were significantly higher than in male bearing pregnancies (P<0.001). Maternal and cord blood estradiol, progesterone, testosterone, DHEAS, prolactin and growth hormone levels were not significantly different in either fetal gender. When all patients were considered as a group there were no correlations between fetal hCG levels and any of the measured hormones. Term fetal DHEAS, estrogen, progesterone, testosterone, growth hormone and prolactin levels do not contribute to different hCG levels between female and male fetuses. It is possible that fetal hypophyseal-adrenal gonadal axis does not play a central role as the cause of different hCG levels.
Tumor volume ratio, based on preoperative MR volumetry, seems to predict deep MI independently in stage I endometrial cancer with insufficient sensitivity and specificity. Its value in clinical practice for risk stratification models in endometrial cancer has to be studied in larger cohort of patients.
Our results showed that adenomyosis is significantly associated with lower stage in endometrial cancer that may suggest a possible limiting effect on endometrial cancer spread. In addition, despite similar rates in disease-free survival and endometrial cancer-related death, overall survival rate was significantly higher in the presence of adenomyosis and might be considered as a good prognostic factor for endometrial cancer.
Our study demonstrated that a cancer antigen 125 level ≥ 35 is the only independent prognostic factor for both progression-free survival and overall survival in patients aged ≤40 years with endometrial cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
