Preoperative clinical characteristics for differentiating malignant transformation from torsion of mature cystic teratoma.

This retrospective study was conducted in 27 patients with malignant transformation of mature cystic teratoma（MT-MCT）and 125 ovarian teratoma patients with torsion who underwent surgery in the First Affiliated Hospital of Wenzhou Medical University from 2008 to 2019. The incidence of MT-MCT in this study was 0.79%. The 3-year overall survival (OS) rate was 69.6 ± 9.6%. The 3-year progression-free survival (PFS) rate was 58.3 ± 9.6%. Kaplan-Meier survival analysis indicated that patients with squamous cell carcinoma (SCC) had significantly shorter OS compared with non-SCC patients. Older age (OR 1.076, 95% CI 1.041-1.111), higher platelet (PLT) level (OR 1.012, 95% CI 1.005-1.020) and lower neutrophil-to-lymphocyte ratio (NLR) level (OR 0.794, 95% CI 0.647-0.915) were independent predictors of MT-MCT. The area under the curve (AUC) for the combined use of age, PLT count and NLR was 0.921 (95% confidence interval 0.877-0.964; p < 0.001), with a sensitivity of 92.6% and a specificity of 80.8%.

Clinical characteristics and prognosis analysis of uterine sarcoma: a single-institution retrospective study.

BACKGROUND: Uterine sarcomas are rare and aggressive gynaecologic malignancies, characterized by a relatively high recurrence rate and poor prognosis. The aim of this study was to investigate the clinicopathological features and explore the prognostic factors of these malignancies. METHODS: This was a single-institution, retrospective study. We reviewed the medical records of 155 patients with pathologically confirmed uterine sarcomas including uterine leiomyosarcoma (ULMS), low-grade endometrial stromal sarcoma (LG-ESS), high-grade endometrial stromal sarcoma (HG-ESS), undifferentiated uterine sarcoma (UUS) and adenosarcoma (AS) between 2006 and 2022. A total of 112 patients who underwent surgery between January 2006 and April 2019 were included in the survival analysis. The current study recorded the clinicopathological, treatment and outcome data to determine clinical characteristics and survival. RESULTS: The most common histopathological type was ULMS (63/155, 40.64%), followed by LG-ESS (56/155, 36.13%) and HG-ESS (16/155, 10.32%). The mean age at diagnosis of all patients was 49.27±48.50 years and 32.90% (51/155) of patients were postmenopausal. Fifteen patients underwent fast-frozen sectioning, 63(54.78%) were diagnosed with malignancy, 29(25.22%) were highly suspected of malignancy that needed further clarification and 23(14.84%) were diagnosed with benign disease. A total of 124(80%) patients underwent total hysterectomy (TH) and salpingo-oophorectomy. Multivariate analyses showed that histological type and tumour size were independent prognostic factors both for overall survival (OS) (p<0.001 and P=0.017, respectively) and progression-free survival (PFS) (p<0.001 and P=0.018, respectively). Tumour stage was only significantly associated with PFS (P=0.002). Elevated preoperative NLR, PLR and postmenopausal status were significantly correlated with shorter PFS and OS in univariate analysis, but no statistically significant difference was found in multivariate analysis. CONCLUSIONS: In patients with uterine sarcoma, in comparison to LMS and LG-ESS, UUS and HG-ESS tend to present as more aggressive tumour with poorer outcomes. Furthermore, larger tumour (>7.5 cm) were an important predictor of shorter PFS and OS.

Clinicalpathologic and Prognostic Significance of CGI-58 in Endometrial Cancer.

Recent studies have reported that CGI-58 played an important role in carcinogenesis and tumoral progression in several cancers. In this study, we investigated the expression and prognostic value of CGI-58 in patients with endometrail cancer. Initially, the expression of CGI-58 was analyzed in 552 cases of endometrial carcinoma from The Cancer Genome Atlas (TCGA). Then, the mRNA level of CGI-58 from 32 normal endometrium and 40 endometrial cancer tissues was determined using real-time PCR. In addition, immunohistochemical staining of CGI-58 was performed in 140 endometrial specimens including 35 normal endometrial tissues, 25 atypical endometrial hyperplasia and 80 endometrial cancers. The expression of CGI-58 was significantly up-regulated in endometrial cancer tissues compared with normal endometrial tissue both in TCGA database and clinical cohorts. Over-expression of CGI-58 was significantly correlated with poor histological differentiation. Furthermore, high levels of CGI-58 expression were significantly associated with shorter overall survival for all analyzed cases. Our findings demonstrate that CGI-58 is up-regulated in endometrial cancer and high CGI-58 expression is a poor prognostic marker for endometrial cancer. CGI-58 may be a potential contributor to endometrial cancer oncogenesis and progression.

A prospective randomized controlled trial comparing two different treatments of intrauterine adhesions.

RESEARCH QUESTION: Intrauterine adhesions (IUA) are primarily caused by trauma to the endometrium, and hysteroscopy is presently the main treatment for IUA. However, high rates of post-operative adhesion re-formation remain a problem. In this study, the combination of an intrauterine device (IUD) with a Foley catheter and the balloon uterine stent were investigated to evaluate their efficacy in preventing adhesion re-formation and the subsequent reproductive outcomes in patients with moderate to severe adhesions. DESIGN: A prospective randomized controlled study was conducted in a university-affiliated hospital. A total of 171 women with Asherman's syndrome were initially recruited between August 2016 and December 2017 and were randomized to undergo either balloon uterine stent insertion or placement of a contraceptive IUD plus a Foley catheter after hysteroscopic adhesiolysis. Reduction of adhesion scores, incidence of adhesion re-formation, changes in menstrual flow and reproductive outcomes were analysed. RESULTS: A total of 118 participants were eligible for analysis. The American Fertility Society (AFS) scores were not significantly different between groups before hysteroscopic adhesiolysis. At the second-look hysteroscopy, the AFS scores and adhesion recurrence rates were significantly higher in the balloon uterine stent group compared with the combination group (P < 0.01 and P = 0.024, respectively). There were no statistically significant differences in pregnancy and live birth rates between the two groups. CONCLUSIONS: The combination of an IUD and a Foley balloon catheter had better efficacy in preventing adhesion re-formation than the balloon uterine stent alone; however, it did not produce better reproductive outcomes.

Use of cancer antigen 125, cancer antigen 19-9, and the neutrophil-to-lymphocyte ratio to diagnose mature cystic teratoma with torsion.

OBJECTIVE: To determine the efficacy of serum levels of cancer antigen 125 (CA125) and cancer antigen 19-9 (CA19-9), and the neutrophil-to-lymphocyte ratio (NLR) for diagnosis of mature cystic teratoma (MCT) with torsion. METHODS: A retrospective medical record review was conducted of data for women who had undergone surgery for ovarian MCT at the First Affiliated Hospital of Wenzhou Medical University, China, between January 1, 2008, and January 1, 2015. Patients with torsion and a control group who underwent surgery on the same days were identified. Clinical characteristics and the serum levels of CA125, CA19-9, and the NLR were assessed. RESULTS: The serum levels of CA125, CA19-9, and the NLR were higher in the torsion group (n=68) than in the control group (n=120; P≤0.001 for all). Receiver operating characteristic analysis indicated that the area under the curve for the combined use of CA125, CA19-9, and NLR was 0.978 (95% confidence interval 0.954-1.000; P<0.001). This combination had a diagnostic sensitivity of 93.9% and a specificity of 98.3%. Moreover, levels of these inflammatory markers were significantly increased among patients with large tumor diameters (P<0.01 for all). CONCLUSION: The combined measurement of CA125, CA19-9, and the NLR provided an efficient method for the diagnosis of MCT with torsion.

A novel prognostic inflammation score predicts outcomes in patients with ovarian cancer.

BACKGROUND: Systemic inflammation and host immunological nutritional status play important roles in the tumorigenesis of malignant cancer. A novel prognostic inflammation score (PIS) based on preoperative serum albumin and neutrophil to lymphocyte ratio (NLR) was designed. We explored its prognostic value in ovarian cancer. METHODS: 143 patients with ovarian cancer were enrolled in this retrospective study. The association of the PIS with clinicopathologic parameters was analyzed. The prognostic significance was determined by univariate and multivariate cox survival analyses. RESULTS: Both univariate and multivariate analyses showed that NLR and albumin were independent prognostic factors for overall survival (OS) and progression-free survival (PFS). An inverse correlation was observed between the NLR and serum albumin concentration. The novel prognostic inflammation score (PIS) was shown to be a significant predictor for OS and PFS (both P<0.001) according to multivariate analysis. Additionally, low PIS was associated with advanced tumor stage (P<0.001), metastasis (P<0.001) and preoperative high PLR (P<0.001). CONCLUSIONS: The PIS is a novel but promising prognostic score in ovarian cancer. It is a significant prognostic marker adjusted for clinicopathologic characteristics to further identify patients' survival differences.
