Purpose: This study aimed to evaluate outcomes and toxicity in patients with endometrial cancer per our institutional adjuvant vaginal cuff brachytherapy (VBT) fractionation scheme.
Methods And Materials: We identified women with International Federation of Gynecology and Oncology stages I and II endometrial cancer who underwent surgical staging and adjuvant high-dose-rate VBT without external beam radiation. All patients received 30 Gy in 6 fractions to the upper one-third of the vagina, prescribed to a depth of 5 mm and delivered twice weekly.
Aggressive angiomyxoma (AA) is a rare mesenchymal tumour that is characterised by increased incidence in women compared with men, local invasion to the surrounding tissue and high recurrence rate. A premenopausal woman presented to clinic with pelvic pressure, intermittent tingling in the thigh and pressure emptying the bladder. CT scan, vaginal and gluteal biopsies, and MRI scan were performed to conclude a final diagnosis of AA.

However, some will require salvage radiation therapy for recurrence. The purpose of this study was to evaluate our experience using salvage radiation for recurrent endometrial cancer in patients who did not receive upfront adjuvant therapy.

Methods And Materials: We retrospectively identified 162 patients with The International Federation of Gynecology and Obstetrics (FIGO) stage I-IVA USC treated at our institution.
Objectives: Radiation is frequently added to chemotherapy for adjuvant treatment of advanced stage endometrial cancer. Multiple adjuvant therapy sequencing options exist, and little data is available to compare these. We compared outcomes and toxicities after "sandwich" chemoradiation (chemotherapy, then radiation, then chemotherapy) and nonsandwich sequences (chemotherapy then radiation, radiation then chemotherapy, or concurrent chemoradiation).

Objective: To determine whether metabolomic based biomarkers can detect EC overall and early-stage EC.
Objectives: Clear cell carcinoma (CCC) comprises a rare yet an aggressive subtype, accounting for less than 5% of all uterine carcinomas. Several clinicopathologic features have been predictive of poor prognosis; however, data remain controversial. The aim of this study was to evaluate the clinicopathologic features of a multi-institutional cohort of endometrial CCC in order to identify which, if any, have prognostic significance.

The HER family, GATA4, and SMAD3 genes are reportedly involved in GCT proliferation and apoptosis and may serve as new predictors of recurrence. The aim of the study was to evaluate novel predictors of recurrence in GCT from a large single institution cohort.

PARP inhibitors target DNA repair and provide a second hit to BRCA mutated tumors, resulting in "synthetic lethality". We investigated a combination of metformin and olaparib to provide "synthetic lethality" in BRCA intact ovarian cancer cells.

In a previous study, we showed that Nanoceria (NCe), nanoparticles of cerium oxide, significantly inhibited production of reactive oxygen species, cell migration and invasion of ovarian cancer cells in vitro, without affecting cell proliferation and significantly reduced tumor growth in an ovarian cancer xenograft nude model. Increased expression of folate receptor-α, an isoform of membrane-bound folate receptors, has been described in ovarian cancer.

CR resulted in activation of energy regulating enzymes adenosine monophosphate activated kinase (AMPK) and sirtuin 1 (SIRT1) followed by downstream inhibition of Akt-mTOR. In the present study, we investigated the effects of metformin on ovarian cancer growth in mice fed a high energy diet (HED) and regular diet (RD) and compared them to those seen with CR in an immunocompetent isogeneic mouse model of ovarian cancer.

Methods: Retrospective analysis of patients with SCC (148 patients) and ADC (130 patients) stages IA1-IB2 who underwent surgery at our three institutions (two from Detroit, one from Mexico) from 2000-2010 was performed for: age, stage, tumor size, lymphovascular invasion (LVI), invasion depth, lymph node status (LN), recurrence and survival.
The incidence of endometrial cancers diagnosed on biopsy that have no residual cancer identified at hysterectomy is not well studied. The aim of our study was to determine the incidence and long-term follow-up of this "vanishing cancer" phenomenon. All slides from the initial biopsy/curettage and hysterectomy specimens were reviewed and the diagnosis confirmed by a gynecologic pathologist.

Methods: Data from four academic institutions were analyzed.
To analyze the clinical significance of the extent of lymphovascular space invasion (LVI) in patients with uterine serous carcinoma. After IRB approval, 232 patients with uterine serous carcinoma from the pathology databases of 4 large academic institutions were included. Patients were divided into 3 groups based on extent of LVI.

The effect of energy balance on ovarian cancer progression was investigated in an isogeneic immunocompetent mouse model of epithelial ovarian cancer kept on a regimen of regular diet, high energy diet (HED) and calorie restricted diet (CRD), prior to inoculating the animals intraperitoneally with the mouse ovarian surface epithelial ID8 cancer cells. Tumor evaluation revealed that mice group on HED displayed the most extensive tumor formation with the highest tumor score at all organ sites (diaphragm, peritoneum, bowel, liver, kidney, spleen), accompanied with increased levels of insulin, leptin, insulin growth factor-1 (IGF-1), monocyte chemoattractant protein-1 (MCP-1), VEGF and interleukin 6 (IL-6).

Methods: A retrospective review was conducted of all primary UCCC cases treated at 1 of 4 major gynecologic cancer centers between 1982 and 2012. Patients and tumor characteristics were retrieved from the cancer databases of the respective institutions and based on a retrospective review of the medical records.
Objective: A subset of uterine serous carcinoma (USC) may have better clinical behavior bringing up the possibility that there may be morphologic features, which would help in their categorization. The aim of this study is to evaluate the potential use of the MD Anderson Cancer Center 2-tier grading system for ovarian carcinoma in USC.
Methods: Tumors assigned a combined score included in this analysis were 1) low-grade: tumors without marked atypia and 12 mitoses/10 high power field (HPF) and 2) high grade: tumors with severe nuclear atypia and >12 mitoses/10 HPF.
Objective: To determine the 30-day prevalence of venous thromboembolism (VTE) after minimally invasive surgery (MIS) for endometrial (EC) and cervical cancers (CC).
Methods: A retrospective cohort study at two large tertiary care centers between 2006 and 2011. Patients having MIS for EC or CC were included.
Objective(s): To evaluate the benefit of adding pelvic radiation treatment (EBRT) to vaginal cuff brachytherapy (VB) for women with early stage uterine serous carcinoma (USC) treated with adjuvant chemotherapy.
Materials And Methods: After institutional review board (IRB) approval, the authors retrospectively identified 56 patients with 2009 International Federation of Gynecology and Obstetrics (FIGO) Stage I-II USC treated with hysterectomy, bilateral oophorectomy +/- lymphadenectomy, adjuvant chemotherapy, and radiation therapy with either VB alone (n = 33) or VB + EBRT (n = 23) between July 1998 and August 2009.
Results: Median age and follow-up were 68.
Objective: To estimate the survival impact of lymphadenectomy in women diagnosed with uterine serous cancer.
Design: Women with a diagnosis of uterine serous cancer were identified from the Surveillance, Epidemiology and End Results Program (SEER) from 1988 to 2007. Only surgically treated women were included.
Objective: Our aim was to evaluate the prognostic significance of the revised 2009 International Federation of Gynecology and Obstetrics (FIGO) staging criteria in patients with uterine serous carcinoma (USC).
Materials And Methods: We retrieved clinical and histopathologic data on women with USC from 2 large academic centers. Age, race, stage, myometrial invasion, angiolymphatic invasion, and adjuvant therapy were analyzed using Kaplan-Meier and Cox regression models.

Purpose: Eicosanoid-related enzymes have been implicated in the pathogenesis of various cancers. Little is known about the relevance of lipoxygenase pathway to ovarian cancer growth. In this study, we examined the role of 12-lipoxygenase (12-LOX), the main human 12-HETE generating enzyme, in the regulation of proliferation and survival in epithelial ovarian cancer.
