Adult-Type Granulosa Cell Tumor with Similar Clinical Findings Seen during Ovarian Cystectomy Performed at the Same Time as Laparoscopic Ovarian Drilling for Polycystic Ovarian Syndrome: An Extremely Rare Case

Polycystic ovary syndrome (PCOS) is a major cause of anovulatory infertility. Laparoscopic ovarian drilling (LOD) is a treatment for PCOS that allows the laparoscopic identification of other intra-abdominal lesions and the provision of diagnostic treatment. This study reports a case of PCOS with an ovarian mass in which LOD was aggressively used and a granulosa cell tumor (GCT) was found. A 34-year-old woman with secondary amenorrhea and irregular menstrual cycles presented to the emergency department with abdominal pain of unknown etiology. Imaging studies revealed a 6-cm left ovarian mass with an internal appearance suggestive of a hemorrhage. The patient’s secondary amenorrhea was subsequently diagnosed as PCOS, and LOD was performed to preserve her fertility. Simultaneously, a cystectomy was performed to evaluate the tumor in the left ovary;the diagnosis was adult-type GCT. Although concomitant GCT and PCOS are extremely rare, the two conditions have similar clinical manifestations. In women of reproductive age, the impact of surgery on future fertility should be considered, and the initial surgical technique should be chosen carefully.

Apoptosis and Expression of Protein TRAIL in Granulosa Cells of Rats with Polycystic Ovarian Syndrome

The relationship between apoptosis of granulosa cells and follicle development arrest in polycystic ovarian syndrome (PCOS) rats, and the contribution of tumor necrosis factor related apoptosis inducing ligand (TRAIL) in apoptosis of granulosa cells were explored. By using sodium prasterone sulfate rat PCOS model was induced. The apoptosis of granulosa cells in ovaries of rats was observed by TdT-mediated dUTP-biotin nick end-labeling (TUNEL), and the expression of TRAIL protein and mRNA in granulosa cells was detected by using immunhistochemical staining and reverse transcription polymerase chain reaction (RT-PCR) respectively. The apoptotic rate and the expression of protein TRAIL in granulosa cells were significantly higher in antral follicles from the PCOS rats than in those from the control rats (P<0.01, P<0.05). There was no significant difference in apoptotic rate and the expression of TRAIL protein in granulosa cells of preantral follicles between the PCOS rats and the control rats (P>0.05). No apoptosis and the expression of TRAIL protein in granulosa cells of primordial follicles were found in the two groups. The expression of TRAIL mRNA was significantly stronger in granulosa cells from the PCOS rats than in those from the con- trol rats (P<0.01). It was suggested that the apoptotic rate in granulosa cells was significantly higher in antral follicle from the PCOS rats than in those from the control rats. TRAIL played a role in regu- lating the apoptosis of granulosa cells in PCOS rats.

THE MODIFIED RADIOIMMUNOASSAY OF SERUM INHIBIN AND ITS VALUE IN MONITORING OVARIAN TUMOR

Objectives and Methods: A modified radioimmunoassay (RIA) of serum inhibin (INH) was developed and applied to measure serum INH contents in 39 fertile and 16 postmenopausal women. Thirty-three cases of ovarian tumors, including granulosa cell tumors and other kinds of ovarian tumors, were monitored by serum INH RIA. Results: The mean value of serum INH contents in follicular, peri-ovulatory and mid-luteal phases of fertile women were 9.48±7.10 pg/ml (2.04～18.53pg/ml), 19.04±9.73 pg/ml (3.49～33.26 pg/ml) and 131.13±110.81 pg/ml (3.49～ 341.10 pg/ml), respectively. Serum INH concentration was negatively correlated with serum FSH concentration, (rs=?0.483,P<0.01). Serum IHN contents were less than 3.6 pg/ml in normal postmenopausal women. The mean value of serum INH contents in ovarian granulosa cell tumor, thecoma, mucinous cystadenocarcinoma and malignant teratoma cases were significantly higher than that of other ovarian tumors, (P<0.01). Serum INH contents were elevated in ovarian granulosa cell tumor, thecoma, mucinous cystadenocaricinoma and endometrioid carcinoma cases with serum CA-125 values in normal range before operation, but serum INH contents decreased to normal range within one week after operation. And consecutive serum INH RIA could be a valuable tool in monitoring for therapeutic effect. Conclusion: Modified INH RIA was of convenient, time-saving and quantitative characteristics, especially with its high sensitivity (<1 pg/ml). There was a regular change of serum INH concentrations during menstrual cycle. INH could inhibit the synthesis and secretion of follicle stimulating hormone (FSH). INH would become a valuable marker for ovarian tumor. INH RIA combined with the measurement of serum CA-125 would be helpful to the early diagnosis, treatment and follow-up for ovarian cancer.

Ovarian Sex Cord-Stromal Tumors in Postmenopausal Women and Total Laparoscopical Management

BACKGROUND: Ovarian sex-cord stromal tumors (SCST) take up 5% of the ovarian neoplasm and may develop in?to?an ovarian mass or a haemoperitoneum. The surgical management of SCST in early-stage adult patients is not well?defined. CASE REPORT: A 69 year-old postmenopausal woman was admitted for metrorrhagia, a right ovary mass and?increasing pelvic pain. Preoperative clinical and instrumental examination suspected an ovarian tumor, and the?laparoscopic right ophorectomy and the frozen section suggested an ovarian SCST. To fast restore and preserve woman?integrity, total laparoscopic hysterectomy (TLH) plus left salpingo-ophorectomy (SO) were performed, without complications?in the short and long term follow-up. CONCLUSION: In the authors’ opinion, the minimally invasive management?of SCST by TLH plus bilateral SO followed by a prolonged surveillance and without intensive surgical staging,?could be an appropriate clinical and surgical choice in elder patient at early stage, since these tumors are slow at?growth, recurring locally and only a long time after initial treatment. We suggest, after a minimally invasive treatment,?a possible “wait and see” option, as in our case report.

A Retrospective Study of Ovarian Sex Cord Stromal Tumors at the Egyptian National Cancer Institute

Background: Ovarian sex cord-stromal tumors are an uncommon heterogeneous group of tumors with different biological behaviors and clinico-patho- logic aspects. Aim of the Work: This study will review the clinico-pathologic aspects of sex-cord stromal ovarian tumors at the National Cancer Institute (NCI), Cairo University, Egypt, as well as their management and follow-up regarding disease free survival and overall survival. Patients and Methods: This retrospective study was conducted at the National Cancer Institute Cairo University, Egypt on female patients with ovarian sex cord stromal tumors in the period from January 2008 to December 2012 with a follow-up period of 24 to 84 months. The age of the patients, different clinical presentations, radiological findings, associated uterine bleeding (need for endometrial biopsy), pre-operative CA125 levels, surgical management done, different histopathological types, different biological behaviors, presence of ascites (and its correlation with the histopathology), Adjuvant chemotherapy (according to biological behavior and pathological type), and follow-up of non-benign cases for up to 84 months will all be documented and studied. Results: The mean age at presentation was 47.34;abdominal pain and mass were the commonest presentations 54.5% and 53.2% respectively;the main radiologic findings were a pelvic mass +/- ascites which had no correlation to the pathological type (p = 0.075). Endometrial hyperplasia and endometrial carcinoma were associated with 22% and 2.5% of cases respectively. Stages I and II represented 95% of patients with non-benign tumors (48 patients). Panhysterectomy +/- infracolic omentectomy or fertility sparing surgery were done in 70.1% and 29.9% of patients respectively. AGCTs were the commonest pathological type (49.4%). Adjuvant chemotherapy was given to 14 patients (46.7%) with non-benign tumors. 6 recurrences (20%) in 30 patients with non-benign tumors on regular follow-up were documented. The median of disease free survival (DFS) was 50.5 months. The median overall survival was 49.5 months. Conclusion: Ovarian SCSTs are uncommon neoplasms with different biological behaviors where AGCTs are the commonest among Egyptian females. Hormonal manifestations are uncommon where abnormal vaginal bleeding is the commonest one. The presence of ascitic fluid has no correlation with the pathological type of the tumor. Early stages (I and II) represented about 95% of non-benign tumors. Surgical management without lymphadenectomy +/- adjuvant chemotherapy is the main line of treatment at our institute. The OS was shorter than that documented in the literature. A small number of patients, reluctance of follow-up and unavailability of some patients’ data were the main drawbacks in this study.

复发性卵巢颗粒细胞瘤的治疗选择及预后

目的探讨复发性卵巢颗粒细胞瘤(ovarian granulosa cell tumor,OGCT)的临床特征,分析其预后影响因素,评估治疗方案。方法回顾性研究38例复发性OGCT患者的临床特征、复发后治疗方法及生存情况。结果38例复发性OGCT患者的中位复发时间为62.5个月(12~308个月),复发后中位生存时间为33个月(9~106个月)。复发性OGCT患者的1年生存率92%,3年生存率71.9%,5年生存率55.5%。单因素分析显示,复发病灶数目、复发后手术治疗是复发性OGCT患者生存预后的影响因素(P>0.05),多因素生存分析结果显示,复发后手术治疗是复发性OGCT患者生存预后的影响因素(P<0.05)。对27例接受手术治疗的复发性患者单因素分析显示,手术残留病灶是复发性OGCT患者术后再次复发的独立危险因素(P<0.05)。结论复发性OGCT的化疗敏感性较低,手术是复发性OGCT最主要的治疗方法,尽可能完整切除可以降低再次复发风险,提高生存率。

Clinicopathological Evaluation of Ovarian Juvenile Granulosa Cell Tumor: Is Fertility-Sparing Surgery Safe?

Objective:To retrospectively investigate the clinicopathological characteristics of ovarian juvenile granulosa cell tumors(JGCTs)and to evaluate the safety of fertility-sparing surgery.Methods:In this study,surgically treated patients with JGCTs diagnosed between January 2004 and October 2018 in our center were identified.Clinicopathological data,survival outcomes,and recurrence rates were examined in these patients.Results:A total of 8 patients were included.All patients were premenarchal girls or young women(age range,9-32 years).Irregular vaginal bleeding was the most common presenting symptom.Of them,seven patients were classified with Stage I JGCTs,and they underwent fertility-sparing surgery.One patient who had Stage IIIC JGCT and had completed childbearing underwent complete surgery.Seven patients received adjuvant chemotherapy.The median follow-up duration in the total cohort was 64 months(range,2-117 months).The overall survival rate in the fertility-sparing group was 100%,whereas the patient with Stage IIIC JGCT died 1 month after the treatment.Conclusions:Fertility-sparing surgery might not show a negative impact on oncologic outcomes.Fertility sparing could be considered a modified option for patients with Stage I JGCTs.However,due to the limited number of patients,the conclusion must be interpreted with caution,and larger or multicenter studies are needed before conclusions can be drawn.
