BACKGROUND: Patients with ovarian cancer tend to receive the highest quality of care at high-volume cancer centers with gynecologic oncologists. However, the care that they receive prior to gynecologic oncology consult has not been examined. We investigated the quantity and quality of care given to patients with ovarian cancer before being seen by a gynecologic oncologist. OBJECTIVES: We evaluated the variability, quantity, and quality of diagnostic testing and physician-referral patterns prior to consultation with a gynecologic oncologist, in women with suspicious pelvic masses seen on imaging...

Importance: Although oral contraceptive (OC) use is common, the influence of OC use on carcinogenesis is not fully understood. A recent Agency for Healthcare Research and Quality report identified a need to understand the consistency of OC use and cancer associations across subpopulations, including smokers and obese women. Objective: To determine whether associations between duration of OC use and risk of specific cancers were modified by lifestyle characteristics...

Context: Androgen excess in women is predominantly due to underlying polycystic ovary syndrome (PCOS). However there is a lack of clarity regarding patterns and severity of androgen excess that should be considered predictive of non-PCOS pathology. Objective: We examined the diagnostic utility of simultaneous measurement of serum dehydroepiandrosterone sulfate (DHEAS), androstenedione (A4) and testosterone (T) to delineate biochemical signatures and cut-offs predictive of non-PCOS disorders in women with androgen excess...

Malignant cells are not the only components of a tumor mass since other cells (e.g., fibroblasts, infiltrating leukocytes and endothelial cells) are also part of it. In combination with the extracellular matrix, all these cells constitute the tumor microenvironment. In the last decade the role of the tumor microenvironment in cancer progression has gained increased attention and prompted efforts directed to abrogate its deleterious effects on anti-cancer therapies. The immune system can detect and attack tumor cells, and tumor-infiltrating lymphocytes (particularly CD8 T cells) have been associated with improved survival or better response to therapies in colorectal, melanoma, breast, prostate and ovarian cancer patients among others...

Poly-ADP-ribosylation (PARylation) is a protein posttranslational modification (PTM) that is critically involved in many biological processes that are linked to cell stress responses. It is catalyzed by a class of enzymes known as poly-ADP-ribose polymerases (PARPs). In particular, PARP1 is a nuclear protein that is activated upon sensing nicked DNA. Once activated, PARP1 is responsible for the synthesis of a large number of PARylated proteins and initiation of the DNA damage response (DDR) mechanisms. This observation provided the rationale for developing PARP1 inhibitors for the treatment of human malignancies...

A quantitative mass spectrometry imaging (QMSI) method for absolute quantification of glutathione (GSH) in healthy and cancerous hen ovarian tissues using infrared matrix-assisted laser desorption electrospray ionization (IR-MALDESI) is presented. Using this technique, the ion abundance of GSH was normalized to that of a structural analogue, which was sprayed on the slide prior to mounting the tissue sections. This normalization strategy significantly improved the voxel-to-voxel variability; the variability is attributed to the overall ionization process...

BACKGROUND: Serous borderline tumor (SBT) of the micropapillary type (SBT-MP) became one of the major pathological SBT diagnoses in addition to typical SBT, and was also defined as "non-invasive" low-gradeserous carcinoma according to the World Health Organization (WHO) classification in 2014. In this study, we investigated the MRI appearance of SBT-MP compared to that of typical SBT in order to identify specific imaging features of SBT-MP that correspond to pathological findings. METHODS: MR images of 6 histologically proven ovarian SBT-MP in four patients and 14 typical SBT in ten patients were reviewed retrospectively...

Small intestinal tumors are rare with adenocarcinoma of the small intestine accounting for less than 2% of all gastrointestinal cancers. Primary jejunal adenocarcinoma constitutes a minute portion of small intestine adenocarcinomas. Clinically, this cancer presents at latter stages of its progression, mainly due to vague and non-specific symptoms, and the difficulty encountered in accessing the jejunum on upper endoscopy. Diagnosis of jejunal adenocarcinoma is usually inconclusive with the use of computed tomography (CT) scan, small bowel series, or upper endoscopy...

A 32-year-old woman consulted for an evaluation of pelvic pain following intrauterine insemination (IUI). Vaginal and abdominal sonography, septic workup were performed and laparoscopic surgery was scheduled after failure to respond to a course of antibiotics. During laparoscopic surgery, bilateral tubo-ovarian abscesses arising on the endometriotic cysts of both ovaries were identified with a vast amount of brownish peritoneal fluid under the adhesion of the greater omentum. Bilateral ovarian cystectomy, right salpingectomy and lysis adhesion were performed...

OBJECTIVE: Women with type 1 diabetes have increased risk of infertility compared to women without diabetes even after adjustment for irregular menses, but etiologies are incompletely understood. Our aim was to examine the prevalence of abnormalities in ovarian markers consistent with polycystic ovary syndrome in women with type 1 diabetes and associations with irregular menses and diabetes-specific variables. DESIGN, PATIENTS, AND MEASUREMENTS: We conducted a secondary analysis of women in the Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications Study (DCCT/EDIC), a randomized trial and observational follow-up of intensive insulin therapy for type 1 diabetes...

RATIONALE: Leiomyomas arising from the anterolateral abdominal wall are uncommon, and their pathogenesis remains unknown. We present the 15th case of such a tumor, having this unique tumor morphology, followed by a detailed discussion on disease pathogenesis. PATIENT CONCERNS: A 48-year-old, asymptomatic perimenopausal, multiparous Japanese woman presented with a left-sided pelvic mass. She had no history of previous surgeries or uterine leiomyomas. Although a transabdominal ultrasonogram raised suspicions of an ovarian tumor, a transvaginal ultrasonogram confirmed normal ovaries...

A 15 months-old Simmental heifer (SH) and a 18 months-old Marchigiana heifer (MH) were referred to the Faculty of Veterinary Medicine of Teramo (Italy). In the rst heifer, clinical examination of the vulva, vestibulum, and vagina showed no signs of disease and no discharge was detected. Palpation per rectum revealed a mass in the left portion of the abdominal cavity, closely attached to the tip of the left uterine horn. The mass was mainly rm and brous and its surface was slightly lobulated. The second heifer had a history of a regular cycle from the 11th to the 14th month of age followed by an anoestrus state...

Reproductive functions in female mammals can be significantly affected by the actions of dietary polyunsaturated fatty acids (PUFAs) on steroid hormone secretion rates. Nevertheless, the effects of plasma free PUFAs on the oestrous cycle have seldom been considered. Therefore, in the present study, the diet of domestic guinea pigs was supplemented with high concentrations of different PUFAs and the effects of altered plasma PUFA patterns on steroid hormone concentrations, measured non-invasively, and body mass during oestrus and dioestrus were analysed...

Purpose: In 75% of ovarian cancer patients the tumor mass is completely eradicated by established surgical and cytotoxic treatment; however, the majority of the tumors recur within 24 months. Here we investigated the role of circulating tumor cells (CTCs) indicating occult tumor load, which remains inaccessible by established diagnostics. Experimental design: Blood was taken at diagnosis (baseline samples, n = 102) and six months after completion of adjuvant first-line chemotherapy (follow-up samples; n = 78)...

Small cell carcinoma of ovary-hypercalcemic type is an undifferentiated carcinoma. We describe two cases in women aged 32 and 29. Both presented with large masses and complete surgical extirpation was impossible. Histologically, the images were similar, with diffuse cell proliferation, accompanied by the presence of follicle-like spaces. In both cases it was necessary to make a differential diagnosis with entities such as adult or juvenile granulosa cell tumour, small cell carcinoma of pulmonary type, dysgerminoma and even peripheral neuroectodermal tumour...
