The relationship between serum CA-125 level and recurrence in surgical stage I endometrial cancer patients.

BACKGROUND: The majority of patients diagnosed with early stage endometrial cancer have a favorable prognosis; however, approximately 10% to 15% experience a recurrence. Therefore, the aim of the present study was to evaluate whether postoperative carbohydrate antigen 125 (CA-125) levels could be used to predict recurrence and recurrence-free survival (RFS) in patients with surgical stage I endometrial cancer. METHODS: We enrolled a total of 518 patients with stage I endometrial cancer who underwent surgical treatment between January 2010 and March 2019. Serum CA-125 levels were measured prior to surgery, as well as 6 to 12 months after surgery. Subsequently, the correlations between the CA-125 levels, cancer recurrence, and RFS were analyzed. RESULTS: Although the preoperative CA-125 level was not associated with the risk of cancer recurrence, the postoperative CA-125 level was found to be the only independent predictor of recurrence in both univariate and multivariate analyses. Additionally, we found that a postoperative CA-125 cutoff value of 13.75 U/mL yielded the best sensitivity and specificity for predicting cancer recurrence. Patients with a postoperative CA-125 level ≥13.75 U/mL, and those with a level <13.75 U/mL, had a median time to recurrence and a 5-year RFS rate of 35.5 vs 50.5 months and 84.7 vs 94.4%, respectively. Additionally, postoperative CA-125 levels were not found to be correlated with preoperative levels. CONCLUSION: In patients with stage I endometrial cancer, a postoperative CA-125 level ≥13.75 U/mL was found to be significantly correlated with a higher recurrence rate, as well as a shorter RFS. Therefore, obtaining a follow-up CA-125 level within 6 to 12 months after staging surgery may be a promising noninvasive biomarker for predicting recurrence.

Late Menarche, Not Reproductive Period, Is Associated with Poor Cognitive Function in Postmenopausal Women in Taiwan.

Female sex hormones such as estrogen and progesterone play an important role in the regulation of a woman's body, including cognition and neurogenesis. However, the effects of age at menarche and reproductive period on cognitive function are still controversial. The aim of this study was to investigate the relationships between age at menarche and reproductive period with cognitive impairment. Data were obtained from the Taiwan Biobank. Cognitive function was assessed using the Mini Mental State Examination (MMSE) and its five subdomains. Multivariable linear regression analysis revealed that an old age at menarche (per one year; coefficient ß, -0.189; p = 0.020) was significantly associated with a low total MMSE score, whereas reproductive period (p = 0.733) was not significantly associated with total MMSE score. Furthermore, an old age at menarche was significantly associated with low MMSE G2 (registration) (per one year; coefficient ß, -0.022; p = 0.035) and G5 (language, construction and obey) scores (per one year; coefficient ß, -0.054; p = 0.047). However, age at menarche was not significantly associated with MMSE G1 (orientation), G3 (attention and calculation) and G4 (recall) scores. In addition, reproductive period was not significantly associated with any MMSE subscores. Late menarche was associated with poor cognitive function, including low total MMSE score and low MMSE G2 and G5 scores. However, reproductive period was not associated with cognitive function in postmenopausal women.
