High-grade serous carcinoma (HGSC) is the most common and lethal ovarian cancer subtype. PARP inhibitors (PARPi) have become the mainstay of HGSC-targeted therapy, given that these tumors are driven by a high degree of genomic instability (GI) and homologous recombination (HR) defects. Nonetheless, approximately 30% of patients initially respond to treatment, ultimately relapsing with resistant disease.

The benefit of MGPT for many common malignancies remains to be determined. In this study, we evaluated up-front MGPT in unselected patients with endometrial cancer (EC) to determine the frequency of PVs in cancer susceptibility genes.

Background: Induction abortion in the second trimester may be favored in some instances, such as in women with compounding medical conditions or when skilled providers are not available. Various methods of pre-induction cervical preparation have been used to shorten the length of induction and decrease the risk of complications. The benefits of cervical preparation with laminaria before D&E have been well studied, but the benefits of laminaria before medical induction are less clear.

The structural, molecular, and biological basis by which the most recurrent endometrial carcinoma-specific mutation site P179 facilitates features of endometrial carcinoma malignancy has yet to be fully determined. Here, we used a series of structural, biochemical, and biological approaches to investigate the impact of the P179R missense mutation on PP2A function.

Methods: Patients who underwent surgery for EMCA from 2011 to 2012 were identified from the American College of Surgeons - Nastional Surigical Quality Improvement Project (ACS-NSQIP) database. Current Procedural Terminology (CPT) codes were used to identify surgical characteristics.
Background: Malignant ovarian germ cell tumors are rare, and often treatable with surgery and chemotherapy. Few data are available for treatment of platinum-resistant tumors.
Case: A 31 year old gravida 0 with a 20 cm pelvic mass was found to have a malignant ovarian germ cell tumor after she underwent debulking surgery.
Objective: To examine the impact of operative time on the development of post-operative medical and surgical complications in patients undergoing minimally-invasive surgery for endometrial cancer.
Methods: Patients who underwent laparoscopic surgery for endometrial cancer from 2005 to 2014 were identified from the ACS-NSQIP database. Operative times were initially divided into hour-long intervals and complication rates were determined.
In patients with Lynch syndrome, gynecologic cancer often can be the first presenting malignancy. In this review, we summarize the genetics of Lynch syndrome and review the various modalities of identifying patients at risk for this syndrome. The clinical characteristics of Lynch-associated endometrial cancer and screening and risk-reducing strategies also are described.

Materials/methods: We performed a retrospective review of patients with Stage II to IV high-grade epithelial ovarian, tubal, and peritoneal carcinoma who underwent primary debulking surgery followed by adjuvant chemotherapy from 2005 to 2013. Patients were divided into 2 groups: Control (those who received their first cycle of chemotherapy within 6weeks of debulking surgery) vs.
Background/aims: The aim of this study is to compare the distribution of anatomic sites of first recurrence in African American (AA) patients with ovarian carcinoma compared to Caucasians.
Methods: Patients diagnosed with high-grade epithelial ovarian, fallopian tube or peritoneal carcinoma from 2007 to 2013 were identified. Patterns of recurrence were compared for AA and Caucasian patients.

Resistance to platinum-based chemotherapy is the major barrier to treating epithelial ovarian cancer. To improve patient outcomes, it is critical to identify the underlying mechanisms that promote platinum resistance. Emerging evidence supports the concept that platinum-based therapies are able to eliminate the bulk of differentiated cancer cells, but are unable to eliminate cancer initiating cells (CIC).

Methods: This is a multi-institutional retrospective study for 115 patients with stage IA non-invasive UPSC (confined to endometrium) treated between 2000 and 2012. Kaplan-Meier and multivariable Cox proportional hazards regression modeling were used.
Objectives: To investigate the impact of adjuvant vaginal brachytherapy on vaginal recurrence in stage I non-invasive uterine papillary serous carcinoma (UPSC).
Methods: This is a retrospective multi-institutional study from 2000-2012. 103 patients who underwent surgical treatment with non-invasive stage IA UPSC were included.

Most cases are diagnosed at an early stage and have low-grade histology, portending an overall excellent prognosis. There exists a subgroup of patients with early, high-risk disease, whose management remains controversial, as current data is clouded by inclusion of early stage tumors with different high-risk features for recurrence, unstandardized protocols for surgical staging, and an evolving staging system by which we are grouping these patients.

Methods: In a retrospective study of women with a body mass index (BMI) of greater than or equal to 35 who underwent gynecologic oncology surgery at Thomas Jefferson University Hospital, Philadelphia, between January 2005 and August 2011, patients were divided into 2 cohorts: those who had surgery with concurrent panniculectomy, and those who had surgery via standard laparotomy. Postoperative complications and lymph node (LN) yield were compared between the groups.
Objective: To determine whether potassium chloride (KCl)-induced feticide prior to termination by dilation and evacuation (D&E) improves surgical outcome.
Methods: We conducted a retrospective study of women who underwent second-trimester (13 0/7 to 23 6/7 weeks) D&E at an urban university-based hospital between January 2000 and July 2010. Women were divided into 3 cohorts: (1) D&E for termination of pregnancy after feticide, (2) D&E without feticide, and (3) D&E for spontaneous pregnancy loss.
We demonstrate that the unique green algal iron assimilatory protein, FEA1, is able to complement the Arabidopsis iron-transporter mutant, irt1, as well as enhance iron accumulation in FEA1 expressing wild-type plants. Expression of the FEA1 protein reduced iron-deficient growth phenotypes when plants were grown under iron limiting conditions and enhanced iron accumulation up to fivefold relative to wild-type plants when grown in iron sufficient media. Using yeast iron-uptake mutants, we demonstrate that the FEA1 protein specifically facilitates the uptake of the ferrous form of iron.
