Study objective In order to reduce the risk of vaginal recurrence, we have chosen total laparoscopic modified radical hysterectomy instead of extrafascial hysterectomy in the treatment of endometrial cancer. The aim of this study was to assess the safety of this method. Design Retrospective study of gynecological patients. Setting Yokohama City University Medical Center, Yokohama, Japan. Patients Forty-nine patients who underwent total laparoscopic modified radical hysterectomy for the treatment of endometrial cancer at our hospital between December 2011 and September 2015. Interventions Total laparoscopic modified radical hysterectomy + bilateral salpingo-oophorectomy (n = 20), total laparoscopic modified radical hysterectomy + bilateral salpingo-oophorectomy + pelvic lymphadenectomy (n = 18), or total laparoscopic modified radical hysterectomy + bilateral salpingo-oophorectomy + pelvic and para-aortic lymphadenectomy (n = 11). Measurements and Main Results The surgical outcomes were analyzed and compared to previous reports. The median operative time was 204 minutes (range, 99–504 minutes) and the median intraoperative blood loss was 150 mL (range, 0–680 mL). No patients needed a blood transfusion, conversion to laparotomy, or reoperation. Intra- and postoperative complications were observed in three patients and nine patients, respectively. The amount of blood loss and the incidence of complications in our study were almost identical to previous reports of laparoscopic hysterectomy. The operative time in our study was equivalent to previous reports of total laparoscopic modified radical hysterectomy. Conclusion Total laparoscopic modified radical hysterectomy is safe and feasible for the treatment of early stage endometrial cancer. This procedure can be an alternative to total laparoscopic hysterectomy, especially when the uterus must be removed completely.

Objective To examine the necessity and sufficiency of different types of hysterectomy for the surgical treatment of endometrial cancer. Methods This was a multicenter collaborative study conducted by 11 institutions. Among patients with stage I–III endometrial cancer who underwent surgery as the initial treatment (only chemotherapy was provided if adjuvant therapy was needed) from 2001 to 2012, we retrospectively examined the type of hysterectomy, clinicopathological factors, recurrence rate over a maximum period of 5 years, and the site of recurrence. The local recurrence rate was examined by univariate and multivariate analyses. Results Among 1335 patients, 982 (73.6%) underwent simple hysterectomy (SH) and 353 (26.4%) underwent modified radical hysterectomy (mRH) and were observed for a mean duration of 51.8 months. No significant difference was observed in the rate of local recurrence between the SH and mRH groups (p = 0.928). In multivariate analysis, clinicopathological factors independently associated with localized recurrence included postmenopausal status [hazard ratio (HR) 5.036, 95% confidence interval (CI) 1.506–16.841, p = 0.009], with stages II (HR 3.337, 95% CI 1.701–6.547, p

e18077 Background: Tissue factor pathway inhibitor 2 (TFPI2) is a novel serum biomarker that discriminates ovarian clear cell carcinomas (CCC) from borderline ovarian tumors (BD) and non-CCC epithelial ovarian cancers (EOC). We examined the prediction performances of TFPI2, including high specificity, for preoperative diagnosis of CCC in multi-center settings. Methods: We collected serum samples obtained preoperatively from patients with ovarian masses who needed surgical treatment to confirm pathological diagnoses in five hospitals in Japan. The diagnostic powers of serum levels of TFPI2 (cutoff value 270 pg/mL) and CA125 (cutoff value 35 U/mL) to discriminate CCC from BD, non-CCC-EOC, and benign lesions were compared. Results: A total of 351 patients (77 ovarian benign lesions, 65 BD and 209 EOC including 69 CCC) were analyzed. Serum TFPI2 levels were significantly higher in CCC patients (mean±SD, 508.2±812.0 pg/mL) than in patients with benign lesions (154.7±46.5), BD (181±95.5) and non-CCC EOC (265.4±289.1). TFPI2 had a high diagnostic specificity to CCC (sensitivity and specificity: 43.5% and 79.5%, respectively). The sensitivity of TFPI2 was improved to 71.1% when combined with CA125, and it was increased in Stage II–IV CCC (66.7%) compared with Stage I CCC (33.3%). In patients with benign endometriotic cysts (BEM), no patient was positive for TFPI2 but 71.4% (15/21) were CA125 positive. TFPI2 showed good performance in discriminating Stage II–IV CCC from BD and non-CCC EOC patients (AUC 0.815 for TFPI2 versus 0.505 for CA125) or from BEM (AUC 0.957 for TFPI2 versus 0.748 for CA125). Conclusions: High specificity of TFPI2 for the preoperative detection of CCC was re-verified with the defined cutoff level of TFPI2 in practice. TFPI2 and CA125 may have a substantial contribution to the precise prediction of intractable CCC. [Table: see text]

Empty follicle syndrome (EFS) has been defined as a condition where no oocytes can be retrieved for in vitro fertilization (IVF) even though ultrasound findings and estradiol (E2) levels suggest the presence of potential follicles. The EFS is a rare condition with an incidence of 0.5–7 % of women undergoing IVF treatments. Although there are many hypotheses as to the cause of EFS, including advanced ovarian age, drug‐related problems, and dysfunctional folliculogenesis, its cause remains unknown. A 37‐year‐old woman with endometriosis and a 5‐year history of primary infertility underwent IVF treatment for 4 cycles. No oocytes were retrieved in 2 cycles and no fertilized eggs were obtained in the other 2 cycles. We assumed that endometriosis adversely affected folliculogenesis and fertilization. Aspiration of an endometrial cyst in the right ovary and subsequent administration of oral contraceptives resulted in successful folliculogenesis and fertilization. Thereafter, she conceived and delivered a 2,662 g female infant at 38 weeks of gestation. Here, we report a case of EFS who conceived in the 5th IVF cycle after aspiration of an endometrial cyst. We assumed that endometriosis might have been involved in the dysfunction of folliculogenesis and EFS.

Study Objectives: The aim of this study is to evaluate the effects of vaginal estriol therapy in total laparoscopic hysterectomy (TLH) with gonadotropin-releasing hormone agonist (GnRH-a) treatment. Design: Retrospective analysis. Design Classification: Canadian Task Force classification II-2. Settings: Department of Gynecology, Yokohama City University Medical Center, Japan. Methods: We retrospectively investigated 50 fibroid cases that had TLH with preoperative GnRH-a treatment and compared the surgical outcome with or without vaginal estriol use (1mg). Estriol was used administered for two weeks before TLH. Measurements and Main Results: A total of 12 patients (27%) received vaginal estriol (1 mg) for 14 days before TLH. As a result of vaginal estriol treatment, there were no group differences in uterus size reduction with GnRH-a treatment (22% vs. 15%, P = 0.20), uterine removal time through the vagina (12.5 min vs. 18.5 min, P = 0.18), rate of vaginal dehiscence (3% vs. 0%, P = 0.76) or in the rate of perineal laceration (33% vs. 34%, P = 0.55). Conclusion: The use of vaginal estriol treatment before TLH with GnRH-a therapy did not improve surgical outcomes.

The management of acute leukemia during pregnancy is challenging. Delays in treatment for acute leukemia can adversely affect maternal prognosis, but chemotherapy during pregnancy may induce severe adverse effects on the fetus. Here, we report a case of a pregnant woman with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph(+)ALL) who underwent remission induction therapy and successfully delivered a live infant after chemotherapy. The case is a 36-year-old woman diagnosed with Ph(+)ALL in the 27th week of pregnancy. She underwent remission induction therapy including daunorubicin, vincristine, cyclophosphamide, and prednisolone. Imatinib was not used in the induction therapy. She delivered the infant after one course of chemotherapy. The infant and the patient are both alive now, without any major complications.
