    A 20 year-old woman presented with features of a twisted ovarian cyst and had an emergency laparotomy Intraoperative findings revealed bilateral, solid ovarian tumors and a left oophorectomy with biopsy of the contralateral ovary performed. Histopathology report confirmed Burkitt lymphoma of ovary. There was no other evidence of lymphoma elsewhere. The primary Burkitt lymphoma of the ovaries was successfully managed with six courses of highly toxic chemotherapy (Berlin-Frankfurt- Munster 1986 protocol). The patient has remained disease free for the last 36 months.

    Anti-N-methyl-d-aspartate receptor encephalitis is a recently described neurological disorder and an increasingly recognized cause of psychosis, movement disorders and autonomic dysfunction. We report 20-year-old Chinese female who presented with generalized tonic-clonic seizures, recent memory loss, visual hallucinations and abnormal behavior. Anti-N-methyl-d-aspartate receptor encephalitis was diagnosed and a computed tomography scan of abdomen reviewed a left adnexal tumor. We describe the first such case report of a patient with anti-N-methyl-d-aspartate receptor encephalitis who was given a bilateral transversus abdominis plane block as the sole anesthetic for removal of ovarian tumor. We also discuss the anesthetic issues associated with anti-N-methyl-d-aspartate receptor encephalitis. As discovery of tumor and its removal is the focus of initial treatment in this group of patients, anesthetists will encounter more such cases in the near future.

    We report here a rare case of bilateral pure gonadoblastoma which accounts for only 0.2% of all ovarian tumours seen at Universiti Kebangsaan Malaysia from 1980 to 1987. This tumour occurred in an 18 year old Chinese "female" who presented with primary amenorrhoea. Examination showed a phenotypic female with poorly developed external gentalia. Exploratory laparotomy revealed a hypoplastic uterus, rudimentary fallopian tubes and streak gonads. Histological examination of the gonads showed a mixed tumour comprising large germ cells and smaller sex cord derivatives arranged in characteristic nests or islands containing hyaline material.

    INTRODUCTION: Ovarian cancer is one of leading causes of cancer related death in gynecology. CD117 is a tyrosine kinase receptor that plays an important role in regulation of apoptosis, cell proliferation and adhesion by binding to its ligand-stem cell factor. Recent studies demonstrated its aberrant overexpression in various malignancies and concluded that it may play a pivotal role in carcinogenesis.

    AIM: To evaluate CD117 expression in ovarian surface epithelial tumours.

    MATERIALS AND METHODS: This retrospective study included 30 ovarian epithelial borderline, low and highly malignant tumours' formalin-fixed paraffin-blocks (FFPE) tissue blocks. Tissue sections were subjected to the routine haematoxylin-eosin stain and with the anti-CD117 immunohistochemically.

    RESULTS: There is a high significant difference in CD117 expression between borderline and malignant groups (P = 0.001). Additionally, there was significant difference in expression in relation to histopathological type (serous versus non-serous) in low-grade and the high-grade ovarian surface epithelial tumours (p=0.04, p=0.035 respectively). Tumour grade and stage strongly correlates with CD117 expression (p=0.014, p=0.019 respectively).

    CONCLUSION: We concluded that CD117 expression was significantly correlated with higher ovarian tumour grade and stage.

    OBJECTIVE: The potential therapeutic effects of metformin on several cancers were reported. However, the evidence of the effects of metformin on ovarian cancer is still limited and inconclusive. This systematic review and meta-analysis study aim to summarize the existing evidence of the therapeutic effects of metformin on ovarian cancer.

    METHODS: We performed systematic searches using electronic databases including PubMed and EMBASE until December 2012. Key words included "metformin" AND ("ovarian cancer" OR "ovary tumor"). All human studies assessing the effects of metformin on ovarian cancer were eligible for inclusion. All articles were reviewed independently by 2 authors with a standardized approach for the purpose of study, study design, patient characteristics, exposure, and outcomes. The data were pooled using a random-effects model.

    RESULTS: Of 190 studies retrieved, only 3 observational studies and 1 report of 2 randomized controlled trials were included. Among those studies, 2 reported the effects of metformin on survival outcomes of ovarian cancer, whereas the other 2 reported the effects of metformin on ovarian cancer prevention. The findings of studies reporting the effects on survival outcomes indicated that metformin may prolong overall, disease-specific, and progression-free survival in ovarian cancer patients. The results of studies reporting the effects of metformin on ovarian cancer prevention were meta-analyzed. It indicated that metformin tended to decrease occurrence of ovarian cancer among diabetic patients with the pooled odds ratio of 0.57 (95% confidence interval, 0.16-1.99).

    CONCLUSIONS: Our findings showed the potential therapeutic effects of metformin on survival outcomes of ovarian cancer and ovarian cancer prevention. However, most of the evidence was observational studies. There is a call for further well-conducted controlled clinical trials to confirm the effects of metformin on ovarian cancer survival and ovarian cancer prevention.

    Torsion of ovarian tumors occurred predominantly in the reproductive age group. The majority of the cases presented in pregnant (22.7%) than in non-pregnant (6.1%) women. The major presenting symptom was pain but an abdominal mass was palpable in 79.4% of cases. Torsion was more common on the right ovary and 50% were gangrenous at laparotomy. Most of the tumors were benign cystic teratomas. Only 8.7% of the tumors were malignant.

    The primary retroperitoneal serous adenocarcinoma (PRSAC) is a rare malignant tumor of the retroperitoneum. It shares the same pathological and biological behavior with ovarian serous carcinoma. Most of the cases develop as peritoneal adenocarcinoma and rarely occur in the retroperitoneum. It is reported as serous surface papillary carcinoma of the peritoneum and extraovarian peritoneal serous papillary carcinoma. We present a case of PRSAC in a 60-year-old woman. Only 11 cases of PRSAC have been reported from 1983 to 2019. Histopathological features with immunohistochemical expressions are important to diagnose PRSAC. The outcome and survival mainly depend on the possibility of surgical resection. Molecular genetics of PRSAC should also be studied in relation with its ovarian counterpart.

    Primary peritoneal carcinoma (PPC) is a rare tumor that is histologically and immunohistochemically indistinguishable from epithelial ovarian carcinoma. The diagnosis is usually made after excluding gross ovarian involvement or the ovarian involvement is only confined to the surface. A 68-year-old lady presented with right iliac fossa pain and increasing CA125. The CT scan showed bilateral pelvic adnexal masses with peritoneal deposits within the right side of abdomen. She was initially diagnosed as carcinomatosis peritonei from the omental cake removed after exploratory surgery. She was managed as advanced ovarian tumor with peritoneal metastasis and was then administered six cycles of chemotherapy. Surgical intervention included debulking surgery consisting of total abdominal hysterectomy, bilateral salpingooophorectomy and omentectomy and also with right hemicolectomy. The histopathological findings were of primary peritoneal serous carcinoma with only minimal involvement of the serosal surface of the right ovarian capsule. No microscopic invasion into underlying ovarian cortex and stroma was observed. Multiple tumor deposits were also seen over the right paratubal and paraovarian tissue, both parametrium as well as serosal surface of the terminal ileum and periappendicular tissue. Immunohistochemically, the malignant cells were positive to CA125, focally positive to CK7 and negative to CD20 and Calretinin. PPC is one of important differential diagnosis which needs to be considered in cases of advanced ovarian tumor, although the former can only be ascertained after excluding the ovarian involvement microscopically.

    Endometriosis and its complications are not uncommon in Malaysian women. Two cases of ureteric obstruction due to endometriosis are reported and the literature on ureteric obstruction and endometriosis reviewed. It is emphasized that the possibility of ureteric obstruction must be suspected when there is extensive endometriotic disease or if the patient presents with loin pain or pain on one side of the abdomen. Ultrasound scan of the kidneys and, if necessary, an intravenous pyelogram will have to be done on the slightest suspicion. Patients with endometriosis will have to be followed up until the menopause or even later if they are on hormone replacement therapy.

    Protein glycosylation, particularly N-linked glycosylation, is a complex posttranslational modification (PTM), which plays an important role in protein folding and conformation, regulating protein stability and activity, cell-cell interaction, and cell signaling pathways. This review focuses on analytical techniques, primarily MS-based techniques, to qualitatively and quantitatively assess N-glycosylation while successfully characterizing compositional, structural, and linkage features with high specificity and sensitivity. The analytical techniques explored in this review include LC-ESI-MS/MS and MALDI time-of-flight MS (MALDI-TOF-MS), which have been used to analyze clinical samples, such as serum, plasma, ascites, and tissue. Targeting the aberrant N-glycosylation patterns observed in MALDI-MS imaging (MSI) offers a platform to visualize N-glycans in tissue-specific regions. The studies on the intra-patient (i.e., a comparison of tissue-specific regions from the same patient) and inter-patient (i.e., a comparison of tissue-specific regions between different patients) variation of early- and late-stage ovarian cancer (OC) patients identify specific N-glycan differences that improve understanding of the tumor microenvironment and potentially improve therapeutic strategies for the clinic.

    As part of our ongoing study of the specialised metabolites present in brown algae belonging to the Cystophora genus, eight new steroids including three pairs of diastereoisomers were isolated from Cystophora xiphocarpa (Harvey) (Sargassacea, Fucales). The metabolites identified by standard spectrometric methods are (16S,22S)-16,22-dihydroxyergosta-4,24(28)-dien-3-one and (16S,22R)-16,22-dihydroxyergosta-4,24(28)-dien-3-one, (16S,22S,24R)-16,22,24-trihydroxyporifera-4,28-dien-3-one and (16S,22S,24S)-16,22,24-trihydroxystigma-4,28-dien-3-one along with (16S,22S,24E)-16,22-dihydroxystigma-4,24(28)-dien-3-one and (16S,20S)-16,20-dihydroxyergosta-4,24(28)-dien-3-one. (16S,22S,24E)-16,22-Dihydroxystigma-4,24(28)-dien-3-one possessed the most potent cytotoxicity of the steroids in this series with cell growth inhibitions of GI50 8.7 ± 0.7 μM against colon cancer HT29, GI50 5.6 ± 0.8 μM against the breast cancer line MCF-7 and GI50 4.5 ± 0.2 μM against the ovarian cancer cell line A2780. (16S,22R)-16,22-dihydroxyergosta-4,24(28)-dien-3-one was found to be active against the ovarian cancer cell line A2780 with a GI50 of 6.2 ± 0.1 μM.

    A dinuclear gold(I) pyrrolidinedithiocarbamato complex (1) with a bidentate carbene ligand has been constructed and shows potent in vitro cytotoxic activities towards cisplatin-resistant ovarian cancer cells A2780cis. Its rigid scaffold enables a zinc(II)-based metal-organic framework (Zn-MOF) to be used as a carrier in facilitating the uptake and release of 1 in solutions. Instead of using a conventional dialysis approach for the drug-release testing, in this study, a set of transwell assay-based experiments have been designed and employed to examine the cytotoxic and antimigratory activities of 1@Zn-MOF towards A2780cis.

    Cancers of the ovary and corpus uteri afflict 5% and 3.6% Malaysian women respectively. Ovarian cancer (OC) remained the deadliest gynaecological malignancy in perimenopausal women mainly due to the lack of symptoms until the disease had spread. Ultrasonography could provide a preliminary screening allowing the clinician to tailor subsequent management and counselling for these women.  To support the basis for selective screening, a study on 517 urban disease free women aged 45 years and above, uterus-intact, non-users of HRT was undertaken. This study presented normograms of ovary, uterus and endometrium derived from entry ultrasound assessment. The sample comprised of 58.0% premenopaused and 42.0% postmenopaused women with an average age of 51.27±5.35 years old. Over two thirds were Chinese followed by Malays and Indians. The findings indicated that the average uterine size and endometrial thickness (ET) was 7.21±1.67x4.36±1.30cm and 6.36±3.73mm respectively. Premenopausal women had larger uterus compared to those postmenopaused (p

    471 ovarian tumours were available for study from 1980 to 1987. Epidemiological breakdown by race, age and the histological type of the tumours was obtained. The diagnosis of the individual tumours was based on the World Health Organisation (WHO) histological classification of ovarian tumours. There were 324 (68.8%) benigh and 147 (31.2%) malignant tumours. 253 (53.7%) of the tumours were seen in the Malays. The third decade was the peak age for the benigh tumours, and for the malignant tumours, the fourth and fifth decades. 138 (42.6%) of the benign ovarian tumours were cystic teratomas and 45 (30.6%) of the malignant tumours were cystadenocarcinoma.

    Background: Accuracy of diagnosis with intra-operative frozen sections is extremely important in the evaluation of ovarian tumors so that appropriate surgical procedures can be selected. Study design: All patients who with intra-operative frozen sections for ovarian masses in a tertiary center over nine years from June 2008 until April 2017 were reviewed. Frozen section diagnosis and final histopathological reports were compared. Main outcome measures: Sensitivity, specificity, positive and negative predictive values of intra-operative frozen section as compared to final histopathological results for ovarian tumors. Results: A total of 92 cases were recruited for final evaluation. The frozen section diagnoses were comparable with the final histopathological reports in 83.7% of cases. The sensitivity, specificity, positive predictive value and negative predictive value for benign and malignant ovarian tumors were 95.6%, 85.1%, 86.0% and 95.2% and 69.2%, 100%, 100% and 89.2% respectively. For borderline ovarian tumors, the sensitivity and specificity were 76.2% and 88.7%, respectively; the positive predictive value was 66.7% and the negative predictive value was 92.7%. Conclusion: The accuracy of intra-operative frozen section diagnoses for ovarian tumors is high and this approach remains a reliable option in assessing ovarian masses intra-operatively.

    Leydig cell tumours (LCTs) of the ovary are rare ovarian tumours that usually present with hyperandrogenism. Conventional radiological imagings are helpful in localising these tumours. However, some tumours may be too small to be localised before curative surgical removal. It is important to identify these androgen-secreting neoplasms which originate mostly from adrenals or ovaries because they are potentially malignant and require specific treatment. When conventional imagings are unrevealing, selective ovarian and adrenal venous sampling (SOAVS) is the next option. We report a case of LCT that was localised by SOAVS after results from other imaging modalities remained inconclusive.
