Endometrial carcinoma (EC) is the most common malignant tumor of the female genital tract in developed countries. The prognosis of early stage EC is favorable, but a subset faces high risk of cancer progression or recurrence. EC has a poor prognosis upon progression to advanced or metastatic stages. Therefore, our goal is to build a robust prognostic model for predicting overall survival (OS) in EC patients. In this study, 1571 genes were identified as being associated with OS based on genomewide expression profiles using a training dataset...

INTRODUCTION: Gynecologic oncology patients represent a distinct patient population with a variety of surgical risks. The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database provides an opportunity to analyze large cohorts of patients over extended periods with high accuracy. Our goal was to develop a postoperative risk assessment calculator capable of providing a standardized, objective means of preoperatively identifying high-risk patients in the gynecologic oncology population...

OBJECTIVE: Randomized studies have not demonstrated a survival benefit of routine lymph node dissection in early-stage endometrial cancer. Many surgeons nevertheless perform lymph node dissection in all patients with early-stage endometrial cancer. This study aimed to ascertain the survival outcomes of very low-risk endometrial cancer patients (by the Korean Gynecologic Oncology Group [KGOG] criteria) who did not undergo lymph node dissection. MATERIALS AND METHODS: Medical records of 156 consecutive patients who underwent surgical staging without lymph node dissection were collected from 10 institutions...

Objective: We aimed to investigate the correlation of the size and volume of uterine tumors obtained using positron emission tomography/computed tomography (PET/CT) and pathology specimens in patients with endometrioid-type endometrial cancer (EEC) in the premenopausal period, and to compare the results with those of postmenopausal women. In the premenopausal period, the endometrium uses more glucose than in the postmenopausal period. Therefore, the measurement of uterine tumor size using PET/CT in the premenopausal period may normally be different...

BACKGROUND: Platelet-derived growth factor alpha (PDGFRA) is a gene encoding tyrosine kinase receptor and both EGFR and PDGFRA activate tyrosine kinase. The implication of PGFRA in many cancers and its prognostic significance irrespective to EGFR status in spinal chordoma, gliomas and uterine cancers has shown a need for its investigation in oral squamous cell carcinoma (OSCC). We investigated the prognostic value of PDGFRA mRNA expression in OSCC. PATIENTS AND METHODS: The study was conducted in the department of oral maxillofacial surgery-head and neck oncology, at a tertiary hospital...

INTRODUCTION: The cornerstone of treatment for endometrial carcinoma is total abdominal hysterectomy and bilateral salpingo-oophoprectomy. Pelvic lymphadenectomy, with or without para-aortic lymphadenectomy, plays an important role in the surgical staging of endometrial carcinoma, and provides more accurate prognostic information. AIMS: We aimed to evaluate the value and techniques for SLN mapping in early stage endometrial cancer with low risk for lymph node metastasis and whether selective or systematic lymphadenectomy is needed according to the results of proposed algorithm...

Uterine leiomyosarcoma (u{\hyphen}LMS) and endometrial stromal sarcoma (ESS) are among the most frequent soft tissue sarcomas, which, in adults, lead to fatal lung metastases and have an extremely poor prognosis. Due to their rarity and heterogeneity, there are no suitable biomarkers for diagnosis and prognosis, though some biomarker candidates have appeared. Recently, The Cancer Genome Atlas (TCGA) projects dealing with u{\hyphen}LMS confirmed mutations and deletions in RB1, TP53, and PTEN. In addition, whole{\hyphen}exome sequencing of u{\hyphen}LMS has confirmed and demonstrated frequent alterations in TP53, RB1, α-thalassemia/mental retardation syndrome X-linked (ATRX), and mediator complex subunit 12 (MED12)...

Breast, ovarian, and uterine corpus cancers are common female cancers and categorized as hormone-related diseases. Previous studies reported a unidirectional relationship for each cancer, but few studied the reciprocal association in the same cohort. A population-based study was carried out in Taiwan to test the hypothesis that there are pairwise bidirectional associations among these cancers. Using the same cohort of 110,112 cases with primary female cancers including uterine corpus cancer (11,146 cases), ovarian cancer (12,139 cases), or breast cancer (86,827 cases) from the Taiwan Cancer Registry from 1979 to 2008, the pairwise risks of second cancer among uterine corpus, ovary, and breast cancer cases were evaluated by standardized incidence ratios (SIRs) and the corresponding 95% confidence intervals (CIs) to quantify the excess of second malignancies...

Autophagy is a survival process that maintains homeostasis in all eukaryotic cells. Recent studies show an abnormal autophagic activity in endometriosis, but the role of autophagy is controversial. Homeobox A10 (HOXA10) is a transcription factor necessary for embryonic and adult uterine development, and studies indicate that its expression decreases in endometriosis. Homeobox A10 may negatively regulate autophagy in endometriosis. To test this hypothesis, we measured the expression levels of autophagic biomarkers (beclin-1 and LC3-II) and HOXA10 proteins by Western blotting and messenger RNA (mRNA) by quantitative real-time polymerase chain reaction...

Adverse event (AE)-related costs represent an important component of economic models for cancer care. However, since previous studies mostly focused on specific AEs, treatments, or cancer types, limited information is currently available. Therefore, this study assessed the incremental healthcare costs associated with a large number of AEs among patients diagnosed with some of the most prevalent types of cancer. Data were obtained from a large US claims database. Adult patients were included if diagnosed with and treated for one of the following cancer types: breast, digestive organs and peritoneum, genitourinary organs (including bladder and ovary and other uterine adnexa), lung, lymphatic and hematopoietic tissue, and skin...

After 26 years, we followed up 7348 participants in a 1979-1984 health screening survey in the Jinzu River basin, the heaviest cadmium-polluted area in Japan. We assessed the associations of cadmium exposure levels and mortality from cancer and renal damage, indicated by records of proteinuria and glucosuria in the original survey. Mortality risks (hazard ratios) were analyzed using the Cox proportional hazards model, stratified by sex, after adjusting for age, smoking status, and hypertension, as indicated in the original survey records...

INTRODUCTION: Improvement in preoperative care for the ageing population has resulted in an increasing number of elderly patients to be considered for surgery. With an increased incidence of endometrial cancer, it is inevitable that a significant number of elderly patients are referred for surgery, despite the concerns over co-morbid conditions and diminished cardiopulmonary reserves. AIM: To evaluate the clinical outcomes of laparoscopic hysterectomy for elderly women operated on for endometrial cancer with comparison to younger patients...

Menopause is an important transition in the life of women. It has been estimated that by the year 2030, worldwide 1.2 billion women will be menopausal. The most bothersome symptoms of menopause are believed to be due to declines in estrogen levels in postmenopausal women. Thus, hormone therapy is an effective treatment option for menopausal women, although prolonged use of hormone therapy is associated with a slightly increased risk of breast cancer, thromboembolism, and stroke. A literature search for studies evaluating the effects of hormone therapy in menopausal women with asymptomatic fibroids demonstrated variable effects of hormone therapy on the volume and size of the fibroids...

Combination of chemotherapy and radiotherapy is used to enhance local drug delivery while reducing off-target tissue effects. Anticancer drug doxorubicin (DOX) is loaded into l-cysteine modified G4.5 dendrimer (GC/DOX) and released at different pH values in the presence and absence of γ-radiation. Presence of γ-radiation significantly improves DOX release from the GC/DOX under acidic pH conditions, suggesting that GC dendrimer is a radiation-sensitive drug delivery system. GC/DOX is further evaluated by determining cytotoxicity in uterine cervical carcinoma HeLa cells...
