BACKGROUND: Both ovarian/breast cancers are the most prevalent hormone-associated gynecological-cancers, where uncontrolled cellular proliferations/genetic-errors are noticed. The cancer-antigen125 (CA125), which we assessed presently is an important biomarker in the early detection/monitoring of this disease-pathogenesis. METHODS: Serum/tissue CA125 was measured by solid-phase-Enzyme-linked-immunosorbent-assay in women with ovarian/breast tumors of different types (epithelial/non-epithelial; benign/borderline/malignant)/stages...

Most patients with early stage endometrioid adenocarcinoma are treated with hysterectomy and bilateral oophorectomy to prevent ovarian metastasis. But this surgical menopause leads to some long-term sequelae for premenopausal women, especially for young women of childbearing age. This population-based study was to evaluate the safety of ovarian preservation in young women with stage I endometrioid adenocarcinoma.Patients of age 50 or younger than 50 with stage I endometrioid adenocarcinoma were explored from the Surveillance, Epidemiology, and End Results program database during 2004 to 2013...

Ovarian cancer accounts for 3% of all female cancers and has a high mortality rate among gynecological malignancies. Early diagnosis carries a high survival rate of 93%. So, this study was carried out to assess the knowledge and awareness of Jordanian women about ovarian cancer symptoms and risk factors. A cross-sectional survey design was used; 896 women completed the survey. The mean of total symptoms recognized was low at level of 3.2 ( SD = 2.7) out of 10. The three highest known symptoms among women were as follows: extreme fatigue (43...

Issues of sexuality, intimacy, and early menopause significantly impact the quality of life of patients following the diagnosis and treatment of ovarian cancer. These are undertreated problems. Successful treatment requires the provider's awareness of the problem, ability to identify it, and willingness to treat it. Unfortunately many providers do not address these issues in the pre-treatment or perioperative period. Furthermore, patients do not often alert their providers to their symptoms. While systemic hormone therapy may improve many of the issues, they are not appropriate for all patients given their action on estrogen receptors...

Fibroblast growth factor-16 (FGF16) is a member of FGF9 subfamily, which plays key roles in promoting mitosis and cell survival, and also involved in embryonic development, cell growth, tissue repair, morphogenesis, tumor growth and invasion. However, the successful high-yield purification of recombinant human FGF16 (rhFGF16) protein has not been reported. In addition, lung cancer is a major cause of cancer-related deaths, which threats people's lives and its incidence has continued to rise. Learning pathways or proteins, which involved in lung tumor progression will contribute to the development of early diagnosis and targeted therapy...

BACKGROUND: Epithelial ovarian cancer has the highest mortality of all gynecologic cancers. The poor survival rates are often attributed to the advanced stage at which most of these cancers are detected. We sought to examine the effects of patient demographics, comorbidities and presenting symptoms on diagnostic and referral intervals by location of first presentation (emergency department v. elsewhere) and to identify factors that affect these intervals. METHODS: We performed a retrospective analysis of chart and medical record data for ovarian cancers, with the exceptions of sex cord and germ cell tumours, diagnosed between 2004 and 2010 in Manitoba, Canada...

In the last decade the use of assisted reproduction techniques (ART) significantly increased and, due to the improved quality of the procedures and management of patients, it has led to progressively better outcomes. In parallel, the latest literature data show an increased incidence of ovarian cancer, that to date does not have a protocol with high sensitivity and specificity for early diagnosis. Considering the accumulating evidence about the etiology of ovarian cancer, it has been postulated a correlation between the increasing use of necessary and propaedeutic pharmacological treatments for ART and the increased incidence of this tumor...

BACKGROUND: Constitutional mismatch repair deficiency syndrome results from bi-allelic inheritance of mutations affecting the key DNA mismatch repair genes: MLH1, MSH2, MSH6 or PMS2. Individuals with bi-allelic mutations have a dysfunctional mismatch repair system from birth; as a result, constitutional mismatch repair deficiency syndrome is characterised by early onset malignancies. Fewer than 150 cases have been reported in the literature over the past 20 years. This is the first report of the founder PMS2 mutation - NM_000535...

BACKGROUND: Although immune system plays a key role in the pathogenesis of both endometriosis and ovarian cancer, its function is different. Therefore, we hypothesized, that selected immune parameters can serve as diagnostic markers of these two conditions. The aim of this study was to compare serum and peritoneal fluid concentrations of sHLA-G, IL-10 and TNF-alpha in women with selected ovarian pathologies: benign serous cysts, endometrioma and malignant tumors. Clinical significance of using them for diagnostic purposes in women with serous ovarian cysts, endometriosis, and ovarian cancer, which in the future may improve the early diagnosis of ovarian diseases...

INTRODUCTION: We compared the disease free-survival (DFS) and overall survival (OS) rates of patients with high-grade serous primary fallopian tube cancer (HG-sPFTC) and high-grade serous epithelial ovarian cancer (HG-sEOC). METHODS: 22 early-stage cancer patients (International Federation of Gynecology and Obstetrics (FIGO) stages I-II) with HG-sPFTC were retrospectively evaluated. In addition, 44 control patients diagnosed with HG-sEOC were matched to these patients with respect to tumor stage at diagnosis...

PURPOSE: Evidence suggests that mitochondrial DNA (mtDNA) copy number increases in response to DNA damage. Increased mtDNA copy number has been observed in prostate cancer (PCa) cells, suggesting a role in PCa development, but this association has not yet been investigated prospectively. METHODS: We conducted a nested case-control study (793 cases and 790 controls) of men randomized to the screening arm of the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial (PLCO) to evaluate the association between pre-diagnosis mtDNA copy number, measured in peripheral blood leukocytes, and the risk of PCa...

The lethality of epithelial ovarian cancer (EOC) may be due to common misconceptions regarding etiology and the absence of effective screening and early diagnostic tools. Reviews of histopathological surveys performed on the resected fallopian tubes of breast cancer (BRCA) mutation carriers, who underwent risk-reducing salpingo-oophorectomy, unexpectedly revealed the presence of occult carcinomas of the fallopian tubes. This finding prompted studies that demonstrated the most accredited theory of type II EOC development, which suggests that a large proportion of these tumors are derived from the fallopian tube...

PURPOSE: The survival rates for ovarian cancer patients remain very low, often as a result of late diagnosis due to the asymptomatic course of the early stage disease. Based on the important biological contribution of human chorionic gonadotropin to various key processes including; cell cycle control, DNA repair, cellular differentiation and developmental processes, we hypothesized that genetic polymorphisms in the genes promoter could be associated with ovarian cancer risk. Thus, the purpose of the study was to determine whether particular polymorphisms occur in the promoter region of the human chorionic gonadotropin polypeptide 5 encoding gene, and if so, are they associated with ovarian cancer outcome...

BACKGROUND: Long-term survival rates for most types of childhood cancers have improved dramatically over the past decades. However, because of advances in multimodality treatments, cancer survivors nowadays more often face long-term complications, including diminished gonadal and reproductive function. The aim of this study was to identify whether the use of fertility treatments among early onset (0-34 years) cancer survivors giving birth differed from that among siblings giving birth and to identify the subgroups of cancer survivors that were most likely to require fertility treatments...

STUDY QUESTION: Can controlled ovarian hyperstimulation (COH) for fertility preservation be effectively conducted in women with breast cancer without worsening their prognosis? SUMMARY ANSWER: COH with co-administration of letrozole suppresses oestradiol levels without significantly impacting oocyte yield or decreasing disease-free survival rates. WHAT IS KNOWN ALREADY: Oestradiol has the capacity to stimulate the proliferation of breast cancer cells...

OBJECTIVE: Preventive breast surgery and MRI screening are offered to unaffected BRCA mutation carriers. The clinical benefit of these two modalities has not been evaluated among mutation carriers with a history of ovarian cancer. Thus, we sought to determine whether or not BRCA mutation carriers with ovarian cancer would benefit from preventive mastectomy or from MRI screening. METHODS: First, the annual mortality rate for ovarian cancer patients was estimated for a cohort of 178 BRCA mutation carriers from Ontario, Canada...

While ovarian cancer (OC) is relatively rare, it remains one of the most fatal cancers. Lack of robust screening methods for eOC lead to detection of most cases at advanced stages, and most patients relapse following initial treatment. Areas covered: This review summarizes epidemiology and treatment patterns of epithelial ovarian cancer (eOC). MEDLINE, EMBASE, conference proceedings, and the Cochrane Library were searched using key terms and Medical Subject Headings for ovarian cancer, treatment patterns, and epidemiology to identify articles published from 2005-2015...

Adult-type granulosa cell tumor is a clinically and molecularly unique subtype of ovarian cancer. These tumors originate from the sex cord stromal cells of the ovary and represent 3-5% of all ovarian cancers. The majority of adult-type granulosa cell tumors are diagnosed at an early stage with an indolent prognosis. Surgery is the cornerstone for the treatment of both primary and relapsed tumor, while chemotherapy is applied only for advanced or non-resectable cases. Tumor stage is the only factor consistently associated with prognosis...

Syndrome of inappropriate antidiuretic hormone secretion (SIADH) has various causes including central nervous system disorders, pulmonary and endocrine diseases, paraneoplastic syndromes, and use of certain drugs. SIADH induced by chemotherapy with irinotecan-cisplatin is not a common complication. Here, we review a case of SIADH after treatment with irinotecan-cisplatin. A 45-year-old woman received adjuvant chemotherapy (paclitaxel-carboplatin) for ovarian clear cell carcinoma, but the cancer recurred within 9 months of chemotherapy...

Background: The associations between telomere length and cancer risk are equivocal, and none have examined the association between prediagnosis leukocyte telomere length (LTL) and the risk of developing ovarian cancer.Methods: We prospectively measured LTL collected from 442 ovarian cancer cases and 727 controls in the Nurses' Health Studies and the Northern Sweden Health and Disease Study. Cases were matched to one or two controls on age, menopausal status, and date of blood collection. Odds ratios (OR) and 95% confidence intervals (CI) were estimated using conditional logistic regression...
