Ovarian cancer (OC) is one of the most dangerous gynecological diseases and greatly increases the death risk worldwide. The heterogeneity of the ovarian tumors among patients and the lack of sufficient therapies for these tumors make the selection of the appropriate treatment a hard challenge. Understanding the mechanisms leading to OC becomes an urgent need in order to find out better therapeutic strategies. In this study, we have identified a point mutation (L449S) in the regulatory subunit of PI3K in an OC Lebanese patient. This genomic alteration had not been previously reported in OC and could plausibly enhance the PIK3CA amplification effect in strengthening AKT/mTOR pathway activity and leading to tumorigenesis.

Background: Polycystic ovarian syndrome (PCOS) is a condition characterized by menstrual abnormalities (oligo/amenorrhea) and clinical or biochemical features of hyperandrogenism and may manifest at any age. It is a common cause of female subfertility. All the dimensions of PCOS have not been yet completely explored. Methods: It was a cross sectional comparative study carried out at-GOPD of Shaheed Suhrawardy Medical College & Hospital from January, 2016 to December 2016 on 162 subfertile women. Among them 54 were PCOS group and 108 were non PCOS group. PCOS was diagnosed by (Rotterdam criteria 2003) (i) Oligo or anovulation (ii) hyperandrogenism (iii) Polycystic ovaries. Study was done to evaluate and compare the demographic characteristics, clinical, biochemical and ultrasoundgraphic features of sub-fertile women with and without PCOS. Results: A total of 162 sub-fertile women aged 16-36 years. Mean age was 29.5±5.4. There were significant differences between the two groups in terms of (oligo/amenorrhea), hirsutism, WHR and ovarian ultrasound features. There were no significant differences between two groups in correlations between the level of obesity with the incidence of anovulation, hyperandrogenism or with hormonal features. Conclusion: PCOS is one of the important factors causing Infertility. It is an ill-defined symptom complex needed due attention. There is a need to increase awareness regarding. The clinical features of PCOS are heterogenous thus can be investigated accordingly of selection of appropriate treatment modality. J Shaheed Suhrawardy Med Coll, June 2019, Vol.11(1); 17-23

Analysis of ultrasonic blood flow changes in uterine and ovarian arteries and veins in 92 patients with ovarian cancer and 87 patients with chronic salpingoophoritis has allowed to identify the leading differential diagnostic criteria, which include minimum diastolic blood flow velocity, resistance index, while fast hyperemia, the index of venous outflow diastolic index and index of peripheral resistance. Based on a selection of leading differential diagnostic criteria for ovarian cancer and chronic salpingoophoritis developed a network model of differentiation of these groups of patients, streamlining the differential diagnostic process

Ovarian cancer is a leading cause of death worldwide from gynecological malignancies, mainly because there are few early symptoms and the disease is generally diagnosed at an advanced stage. In addition, despite the effectiveness of cytoreductive surgery for ovarian cancer and the high response rates to chemotherapy, survival has improved little over the last 20 years. The management of patients with ovarian cancer also remains similar despite studies showing striking differences and heterogeneity among different subtypes. It is therefore clear that novel targeted therapeutics are urgently needed to improve clinical outcomes for ovarian cancer. To that end, several membrane receptors associated with pivotal cellular processes and often aberrantly overexpressed in ovarian cancer cells have emerged as potential targets for receptor-mediated therapeutic strategies including specific agents and multifunctional delivery systems based on ligand-receptor binding. This review focuses on the profiles and potentials of such strategies proposed for ovarian cancer treatment and imaging.

In cases of ovarian carcinoma, primary cytoreductive surgery (CRS) is the standard treatment up to stage IIIB, but patient selection for neoadjuvant chemotherapy (NACT) in selected cases is controversial. A total of 200 patients with advanced ovarian cancer were analyzed retrospectively, according to specific selection criteria. Primary CRS was performed in 95 patients (47.5%) and interval CRS after 3–6 cycles of NACT was performed in 105 patients (52.5%). After median follow-up of 35 months, 5-year overall survival was 53.7% in the upfront CRS group and 42.2% in the NACT group. Primary CRS is the standard in advanced stages of ovarian carcinoma, but in certain subset of patients, NACT is preferred. Identifying that group is challenging but feasible. Proper selection of patients is key to successful outcomes.
