OBJECTIVE: Low-grade serous ovarian carcinomas (LGSOCs) are a histological subtype of epithelial ovarian tumors, accounting for fewer than 5% of all cases of ovarian carcinoma. Due to the chemoresistant nature of this subtype a search for more effective systemic therapies is actively ongoing, hormonal therapy showing some degree of activity in this clinical setting. The present study ought to investigate the hormone receptor status of LGSOCs, as a strategy to provide molecular support for patient-tailored hormonal treatments...

We have previously reported on life span shortening as well as increased incidence rates in several neoplasms in B6C3F1 mice that were continuously exposed to 21 mGy/day of gamma rays for 400 days. To clarify whether the life shortening was due to early appearance of neoplasms (shortened latency) or increased promotion/progression, 8-week-old female specific-pathogen-free B6C3F1 mice were gamma-ray irradiated at a low dose rate of 20 mGy/day for 400 days. At 100 days postirradiation, 60-90 mice were sacrificed, and thereafter every 100 days alongside the age-matched nonirradiated controls, for 700 days...

IMPORTANCE: A case of nasal septal perforation secondary to systemic bevacizumab therapy for ovarian cancer is reported. Bevacizumab is a vascular endothelial growth factor A (VEGF-A) inhibitor that is becoming more widely utilized in the oncologic community. There is only one prior report of septal perforation secondary to bevacizumab in the Otolaryngology specific literature. The purpose of this report is: 1) to raise awareness and discuss the literature surrounding the sinonasal complications of bevacizumab and 2) provide workup and treatment recommendations based on the sum of the available literature...

BACKGROUND: Per WHO, 2000 classification, pancreatic mucinous cystic neoplasms (MCN) are defined by presence of ovarian stroma, and are primarily located in the pancreatic body/tail of females. The incidence of MCN and associated malignancy in males, since, standardization of MCN diagnostic-criteria is unknown. METHODS: MCN resections from 2000 to 2014 at eight institutions of the Central-Pancreas-Consortium were included, and divided into early (2000-2007) and late (2008-2014) time-periods...

OBJECTIVE: To assess the ability of preoperative computed tomography scan and CA-125 to predict gross residual disease (RD) at primary cytoreduction in advanced ovarian cancer. METHODS: A prospective, non-randomized, multicenter trial of patients who underwent primary debulking for stage III-IV epithelial ovarian cancer previously identified 9 criteria associated with suboptimal (>1cm residual) cytoreduction. This is a secondary post-hoc analysis looking at the ability to predict any RD...

Mature cystic teratoma co-existing with a mucinous cystadenocarcinoma is an infrequently encountered entity with only a handful of cases reported till date. The possibilities in such a case are either a malignant transformation of a benign teratoma into adenocarcinoma or a collision tumor between a mature cystic teratoma and a mucinous tumour of either a primary ovarian surface epithelial-stromal origin or a secondary from a primary gastrointestinal tract tumour. The importance of distinguishing between the two entities has significant bearing on subsequent therapeutic management...

The cystadenoma of the testis and paratestis arising from an unequivocal oviduct-like structure, which is morphologically almost identical with those of the ovarian surface epithelium. These are very rare benign tumors of young adults. They present as asymptomatic cystic lesions. Bilateral paratesticular cystadenomas are strongly associated with von Hippel-Lindau syndrome and correlate with infertility. It is a neoplasm with low malignant potential. Most cystadenomas are benign but a few cases of malignant transformation of embryonic remnants have been reported in the appendix testis, including cases of adenocarcinoma, cystadenocarcinoma, and a low malignant müllerian-type epithelial tumor...

BACKGROUND: Pregnancy luteoma is a distinctive non-neoplastic hormone dependent lesion arising in pregnancy and mimicking an ovarian tumour. Fewer than 200 cases have been described in the English-language literature. Its clinical and morphological features are characteristic and must be considered in order to prevent diagnostic misinterpretation. To the best of our knowledge the association of pregnancy luteoma with endometriosis has not been reported in literature to date. CASE REPORT: A 30-year-old pregnant woman with no particular past medical history, consulted her gynaecologist at 17 weeks gestation for routine check-up...

Introduction Mammalian target of rapamycin is a pathway to block apoptosis. Recent studies showed that the activity of mammalian target of rapamycin pathway increases in endometriotic lesions. Aim of the present study was to study the effect of everolimus agent, a rapamycin analog, in an experimental endometriosis model. Materials and Methods Endometriosis established by the autotransplantation of uterine tissue in the peritoneal cavity was confirmed in 24 rats. The animals were then randomly divided into three groups to receive either everolimus (1...

OBJECTIVE: The evolving knowledge of ovarian carcinogenesis sets the stage for our understanding of high-grade serous pelvic carcinoma (HGSC). Findings in prophylactic surgery introduced serous tubal intraepithelial carcinoma (STIC) as potential precursor of HGSC. The present study explores whether STIC instead should already be considered as an early stage of HGSC with a need for comprehensive staging and therapy. PATIENTS AND METHODS: We identified all consecutive patients with HGSC who received first-line therapy in our referral center for gynecologic oncology from January 2011 to April 2016...

The case of a 70-year-old woman with progressive renal cell carcinoma (RCC) metastatic invasion of a L3 vertebral hemangioma treated by dual percutaneous radiofrequency ablation (RFA) and vertebroplasty is reported. The patient was surgically treated for RCC in 2001. Chemotherapy and immunotherapy were introduced in 2013 for ovarian, bladder and cerebral metastatic disease. An asymptomatic L3 benign hemangioma was noticed at this time. One-year CT and MRI follow-up studies demonstrated a nodular isolated soft tissue lesion involving the anterior edge of the hemangioma...

Deoxynivalenol (DON) is a frequently found trichothecene mycotoxin that elicits toxic effects on humans and animals. In pigs, DON induces changes in digestive and immune systems. Effects on the reproductive system are scarce and mainly based in in vitro models. The aim of this study was to evaluate, using an ex vivo model, the effects of DON on the morphology of ovaries of pigs in all stages of follicular development. Six 5-month-old pigs were used for sampling the explants. Thirty-six explants were incubated for 48 hours in culture medium (n = 18) or medium containing 10 μM of DON (n = 18)...

BACKGROUND: Ovarian cancer remains the most deadly gynecological cancer with a poor aggregate survival rate; however, the specific rates are highly dependent on the stage of the disease upon diagnosis. Current screening and imaging tools are insufficient to detect early lesions and are not capable of differentiating the subtypes of ovarian cancer that may benefit from specific treatments. METHOD: As an alternative to current screening and imaging tools, we utilized wavelength dependent collagen-specific Second Harmonic Generation (SHG) imaging microscopy and optical scattering measurements to probe the structural differences in the extracellular matrix (ECM) of normal stroma, benign tumors, endometrioid tumors, and low and high-grade serous tumors...

Bladder carcinogenesis and tumour progression is accompanied by profound alterations in protein glycosylation on the cell surface, which may be explored for improving disease management. In a search for prognosis biomarkers and novel therapeutic targets we have screened, using immunohistochemistry, a series of bladder tumours with differing clinicopathology for short-chain O-glycans commonly found in glycoproteins of human solid tumours. These included the Tn and T antigens and their sialylated counterparts sialyl-Tn(STn) and sialyl-T(ST), which are generally associated with poor prognosis...

INTRODUCTION: Retrorectal cysts are rare benign lesions which are frequently diagnosed in middle-aged females. According to their origin and histopathologic features, retrorectal cysts are classified as squamous-lined (dermoid or epidermoid) cysts, postanal gut (tailgut) cysts, and rectal duplications (enteric or enterogenous cysts, enterocystomas). Described in this case report is an extremely unusual patient, a woman who simultaneously had a retrorectal cyst and an ovarian serous cystadenoma in addition to a long history of misdiagnosis and multiple unsuccessful surgeries...

BACKGROUND: Mucosa-associated lymphoid tissue lymphomas can occur in various parts of the body, and half of mucosa-associated lymphoid tissue lymphomas occur in the gastrointestinal tract. Gastric mucosa-associated lymphoid tissue lymphoma is the most common lymphoma of the gastrointestinal tract and primary rectal mucosa-associated lymphoid tissue lymphoma is very rare. Because of the high radiosensitivity of mucosa-associated lymphoid tissue lymphomas, this condition can be controlled with radiotherapy of approximately 30 Gy alone...

REVIEW
K H Lee
Mature ovarian cystic teratoma (also known as ovarian dermoid cyst) is a slow growing encapsulated tumor which contains well differentiated derivations of at least two out of three germ cell layers (i.e., ectoderm, mesoderm and endoderm). The lesion is lined by ectodermally derived squamous epithelium containing skin appendages. The cyst content commonly consists of keratin, sebaceous materials and fat. On CT images, the intracystic globules of sebum/fat could appear as multiple free floating rounde hypoattenuating nodules, giving the classical 'sack-of-marbles' appearance...

A 52-year-old woman with abdominal pain and a feeling of incomplete evacuation visited a local clinic. Enlargement of the right ovary was detected, and the patient was referred to the gynecological department of our hospital. CT and MRI revealed a round-shaped mass, 8 cm in diameter, with cystic and solid components in the Douglas pouch. The patient underwent a laparotomy under the diagnosis of ovarian cancer. Intraoperatively, both the ovaries appeared normal and the tumor strongly adhered to the rectum and uterus...
