BACKGROUND: Studies on the association between obesity and ovarian cancer survival have had conflicting results. We reviewed and quantitatively summarized the existing evidence, exploring potentially important sources of variability, such as the timing of body mass index (BMI) assessment, BMI cut points, references used in multivariate analysis, and ovarian cancer stage. METHODS: Eligible studies were searched using MEDLINE (PubMed), EMBASE, and Cochrane Central Register of Controlled Trials, re

Objectives: Human epidermal growth factor receptor-2 (HER2) and 3 (HER3) belong to the epidermal growth factor receptor (EGFR) family of transmembrane receptor tyrosine kinases. In this study, we assessed HER2/HER3 expression levels in specimens of epithelial ovarian cancer and determined their correlation with clinical features of ovarian cancer. Methods: Tissue microarrays (TMAs) were prepared from paraffin blocks of 105 ovarian tumour samples. HER2, HER3, PI3K, Akt, p-Akt, mTOR, p-mTOR, S6, a

Due to improvements in chemotherapeutic agents, cancer treatment efficacy and cancer patient survival rates have greatly improved, but unfortunately gonadal damage remains a major complication. Gonadotoxic chemotherapy, including alkylating agents during reproductive age, can lead to iatrogenic premature ovarian insufficiency (POI), and loss of fertility. In recent years, the demand for fertility preservation has increased dramatically among female cancer patients. Currently, embryo and oocyte c

HPV load before treatment and infection with multiple hrHPV types were predictors of postoperative hrHPV persistence. HPV 53 was the type most likely to persist, but HPV 16 was the type that was most closely associated with residual/recurrent CIN-2/3.

Surgical proficiency could significantly affect the oncologic outcome in MIS. A prospective study regarding sufficient surgical competence is necessary for elaborate analysis of the feasibility of minimally invasive radical hysterectomy.

AIM: The aim of the present study was to examine the accuracy of high-risk human papillomavirus (HR-HPV) DNA detection as a predictor of residual or recurrent cervical intraepithelial neoplasia (CIN) after treatment of high-grade CIN. METHODS: Ninety-five women treated by conization and loop electrosurgical excision procedure (LEEP) for high-grade CIN were followed-up with HR-HPV DNA testing (Hybrid Capture II test, Digene Diagnostics, Gaithersburg, MD, USA) and cytology at 3, 6, 12, 18 and 24 m

The incidence of vaginal cuff dehiscenceand eviscerationwas significantly higher in TLH than LAVH. The intra-corporeal cuff suture was superior to the vaginal suture to prevent the vaginal cuff complications in TLH.

AIM: Variants of CD44 have been proposed to be important in cancer invasion and metastasis. The purpose of this study was to evaluate the diagnostic and prognostic value of CD44v6 expression in gynecologic malignancies. METHODS: Immunohistochemistry was used to determine the expression of CD44v6 in samples from a series of 65 cases of early cervical cancer, 76 cases of endometrial samples and 57 cases of serous epithelial ovarian tumors. We analyzed the expression of CD44v6 and correlated the fi

BACKGROUND: To compare the vaginal route and laparoscopic suture for vaginal cuff closure (VCC) in patients undergoing a total laparoscopic hysterectomy (TLH). METHODS: A total of 471 women who required hysterectomy were allocated to two groups. 261 women had TLH via VCC by the vaginal route and 210 women had TLH via VCC by laparoscopic suture. All TLHs were performed by the same laparoscopic surgeon. RESULTS: The cuff-related complications included vaginal disruption (3.4%), dehiscence (1.27%),

BACKGROUND AND OBJECTIVES: Only a few studies have reported the learning curve for sentinel lymph node (SLN) detection in gynecologic malignancies. We investigated the learning curve for SLN detection during robot-assisted laparoscopic surgery for endometrial and cervical carcinomas. METHODS: This retrospective analysis included patients with stage IA to IIA1 cervical cancer or stage I to III endometrial cancer who underwent SLN mapping using indocyanine green during robot-assisted laparoscopic
