Toxicity and Efficacy After Adjuvant Vaginal Brachytherapy Using 30 Gy in 6 Fractions for Stages I and II Endometrial Cancer.

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 of left buttock.

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.

Outcomes After Salvage Radiation Therapy for Recurrent Endometrial Cancer in Patients With No Prior Adjuvant Therapy: An Institutional Review.

Purpose: After definitive surgery, women with early-stage, low-risk endometrial cancer are observed. 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.

Combined Adjuvant Chemotherapy and Radiation Therapy Improves Disease-Free Survival for Uterine Serous Cancer.

Purpose: Uterine serous carcinoma (USC) is a rare but aggressive endometrial cancer histology. We reviewed outcomes for patients with USC to identify the best adjuvant treatment strategy.

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.

Sequencing of Adjuvant Chemoradiation for Advanced Stage Endometrial Cancer: Outcomes and Toxicity Profiles.

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).

Metabolomic prediction of endometrial cancer.

Introduction: Endometrial cancer (EC) is associated with metabolic disturbances including obesity, diabetes and metabolic syndrome. Identifying metabolite biomarkers for EC detection has a crucial role in reducing morbidity and mortality.

Objective: To determine whether metabolomic based biomarkers can detect EC overall and early-stage EC.

Clear Cell Carcinoma of the Endometrium: Evaluation of Prognostic Parameters in a Multi-institutional Cohort of 165 Cases.

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.

Granulosa Cell Tumors: Novel Predictors of Recurrence in Early-stage Patients.

Granulosa cell tumors (GCTs) comprise 2% to 5% of ovarian neoplasms, with unpredictable patterns of recurrence. 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.

Folic acid tagged nanoceria as a novel therapeutic agent in ovarian cancer.

Background: Nanomedicine is a very promising field and nanomedical drugs have recently been used as therapeutic agents against cancer. 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.

Metformin prevents aggressive ovarian cancer growth driven by high-energy diet: similarity with calorie restriction.

Caloric restriction (CR) was recently demonstrated by us to restrict ovarian cancer growth in vivo. 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.

The prognostic significance of histologic type in early stage cervical cancer - A multi-institutional study.

Background: Cervical adenocarcinomas (ADC) have been viewed as more aggressive than squamous cell carcinoma (SCC). We analyzed an international cohort of early stage cervical cancer to determine the impact of histologic type.

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.

Vanishing endometrial cancer in hysterectomy specimens: a myth or a fact.

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.

Recurrence patterns and survival endpoints in women with stage II uterine endometrioid carcinoma: a multi-institution study.

Objective: There is paucity of data in regard to prognostic factors and outcome of women with 2009 FIGO stage II disease. The objective of this study was to investigate prognostic factors, recurrence patterns and survival endpoints in this group of patients.

Methods: Data from four academic institutions were analyzed.

Significance of lymphovascular space invasion in uterine serous carcinoma: what matters more; extent or presence?

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.

Dietary energy balance modulates ovarian cancer progression and metastasis.

A high energy balance, or caloric excess, accounts as a tumor promoting factor, while a negative energy balance via caloric restriction, has been shown to delay cancer progression. 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).

Racial disparities in uterine clear cell carcinoma: a multi-institution study.

Objective: The aim of this study was to evaluate the impact of race on the overall survival (OS) and progression-free survival (PFS) of white and African-American patients with uterine clear cell carcinoma (UCCC).

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.

Is the two-tier ovarian serous carcinoma grading system potentially useful in stratifying uterine serous carcinoma? A large multi-institutional analysis.

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.

Outcomes of patients with uterine serous carcinoma using the revised FIGO staging system.

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.

Role of 12-lipoxygenase in regulation of ovarian cancer cell proliferation and survival.

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.

The impact of race on survival in uterine serous carcinoma: a hospital-based study.

Objective: Although less common than endometrioid carcinoma, uterine serous carcinoma (USC) accounts for a disproportionate number of endometrial cancer-related deaths. It is relatively more common in black compared to white women. The aim of our study is to analyze the impact of race on survival in USC.
