    A 62-year-old woman who had received extended hysterectomy and radium-needle insertion for cancer of the uterine corpus at 32 years of age. Following that episode, rectal bleeding persisted for several years before it spontaneously cleared up. Rectal bleeding recurred 29 years later, and a small ulcer was revealed radiographically and endoscopically. The surgically resected specimen showed well differentiated adenocarcinoma penetrating the proper muscle layer. The effect of former radiotherapy remained as around the lesion intimal thickening and obstruction of small arteries. (author)

    Vaginal cuff dehiscence is a rare but serious complication that can develop after hysterectomy. Emergent surgical intervention is required for vaginal cuff dehiscence due to the potential subsequent vaginal evisceration, which may lead to necrosis of the small bowel. A 62-year-old nulliparous woman with a 30-year history of smoking, diabetes mellitus, and rheumatoid arthritis (treated with oral steroids) presented with a vaginal cuff dehiscence. Thirty-eight days before the admission, she had undergone a radical operation including total abdominal hysterectomy for uterine corpus cancer at another hospital. We performed emergent laparoscopic surgery to reduce the prolapsed small bowel into the abdominal cavity and repaired the vaginal cuff with a two-layer continuous closure using absorbable barbed sutures. The patient experienced no postoperative complications, and no recurrence of the vaginal cuff dehiscence occurred. Vaginal cuff dehiscence and evisceration can be surgically managed using an abdominal, vaginal, or laparoscopic approach, and the choice of method should be based on patient characteristics and the surgeon's skills. Laparoscopic vaginal cuff repair with a two-layer continuous closure using absorbable barbed sutures is a minimally invasive technique that is safe and effective for medically stable patients with no small bowel injury or vascular compromise and no pelvic abscess.

    Full Text Available This paper presents a single-institution experience regarding the clinicopathologic features and treatment strategies used in uterine clear cell cancer (UCC, a rare, aggressive histologic subtype of uterine cancer with poor prognosis and discusses parameters associated with progression-free survival (PFS and overall survival (OS. A retrospective chart review was performed on all patients (=80 diagnosed with UCC and treated between 1994 and 2009 at a single academic institution. Data on demographics, FIGO stage, treatment regimens, and recurrences were collected. Patients with early-stage UCC had an excellent survival regardless of adjuvant therapy. Advanced-stage patients had a worse survival. Vaginal apex brachytherapy was associated with an increased OS (=0.02 but not PFS (=0.10. The use of platinum-based chemotherapy in combination with vaginal apex brachytherapy did not significantly improve survival. Innovative therapies still need to be identified for this uncommon uterine cancer.

    Full Text Available A 47-year-old, single, Chinese woman presented with pain on the 1st day of menses for more than 30 years. Her dysmenorrhea worsened over years and underwent a total abdominal hysterectomy and bilateral salpingooophorectomy. The myometrium showed trabeculated appearance, and there were adhesions between ovaries and fallopian tubes. A pale solid brownish mass measuring 1.5 cm and times; 1 cm and times; 0.6 cm with fibrous whitish cut surfaces was present on the lateral wall of the uterus in the lower uterine segment. Histologically, adenomyosis and left ovarian endometriosis were confirmed. The lateral uterine wall nodule showed a tubular structure lined by ciliated pseudostratified columnar epithelium. Smooth muscle bundles were found around the entire tubular structure. Lobules of salivary type glands containing both serous and mucous cells are present. The pathological diagnosis of heterotopic respiratory mucosa (HRM was made. To our knowledge, this is the first reported case of HRM of the uterine corpus.

    Full Text Available Abstract Background Teratomas are the commonest germ cell tumours and are most frequently found in the testes and ovary. Extragonadal teratomas are rare and mainly occur in midline structures. Uterine teratomas are extremely rare with only a few previous case reports, usually involving mature teratomas of the uterine cervix. Case Presentation We report an 82-year-old lady presenting with post-menopausal bleeding. Initial investigations revealed a benign teratoma of the uterus which was removed. Her symptoms persisted and a recurrent, now malignant, teratoma of the uterine corpus was resected at hysterectomy. Six months after surgery she relapsed with para-aortic lymphadenopathy and was treated with a taxane, etoposide and cisplatin-containing chemotherapy regimen followed by retroperitoneal lymph node dissection. Conclusion In this report we discuss the aetiology, diagnosis and management of uterine teratomas, and review previous case studies.

    Full Text Available The regulation of transcriptome expression level is a complex process involving multiple-level interactions among molecules such as protein coding RNA (mRNA, long noncoding RNA (lncRNA, and microRNA (miRNA, which are essential for the transcriptome stability and maintenance and regulation of body homeostasis. The availability of multilevel expression data enables a comprehensive view of the regulatory network. In this study, we analyzed the coding and noncoding gene expression profiles of 301 patients with uterine corpus endometrial carcinoma (UCEC. A new method was proposed to construct a genome-wide integrative network based on variance inflation factor (VIF regression method. The cross-regulation relations of mRNA, lncRNA, and miRNA were then selected based on clique-searching algorithm from the network, when any two molecules of the three were shown as interacting according to the integrative network. Such relation, which we call the mRNA-lncRNA-miRNA triplet, demonstrated the complexity in transcriptome regulation process. Finally, six UCEC-related triplets were selected in which the mRNA participates in endometrial carcinoma pathway, such as CDH1 and TP53. The multi-type RNAs are proved to be cross-regulated as to each of the six triplets according to literature. All the triplets demonstrated the association with the initiation and progression of UCEC. Our method provides a comprehensive strategy for the investigation of transcriptome regulation mechanism.

    To apply 3D multifrequency MR elastography (3DMMRE) to the uterus and analyse the viscoelasticity of the uterine tissue in healthy volunteers considering individual variations and variations over the menstrual cycle. Sixteen healthy volunteers participated in the study, one of whom was examined 12 times over two menstrual cycles. Pelvic 3DMMRE was performed on a 1.5-T scanner with seven vibration frequencies (30-60 Hz) using a piezoelectric driver. Two mechanical parameter maps were obtained corresponding to the magnitude (vertical stroke G* vertical stroke) and the phase angle (φ) of the complex shear modulus. On average, the uterine corpus had higher elasticity, but similar viscosity compared with the cervix, reflected by vertical stroke G* vertical stroke {sub uterine} {sub corpus} = 2.58 ± 0.52 kPa vs. vertical stroke G* vertical stroke {sub cervix} = 2.00 ± 0.34 kPa (p < 0.0001) and φ {sub uterine} {sub corpus} = 0.54 ± 0.08, φ {sub cervix} = 0.57 ± 0.12 (p = 0.428). With 2.23 ± 0.26 kPa, vertical stroke G* vertical stroke of the myometrium was lower in the secretory phase (SP) compared with that of the proliferative phase (PP, vertical stroke G* vertical stroke = 3.01 ± 0.26 kPa). For the endometrium, the value of vertical stroke G* vertical stroke in SP was 68 % lower than during PP (PP, vertical stroke G* vertical stroke = 3.34 ± 0.42 kPa; SP, vertical stroke G* vertical stroke = 1.97 ± 0.34 kPa; p = 0.0061). 3DMMRE produces high-resolution mechanical parameter maps of the uterus and cervix and shows sensitivity to structural and functional changes of the endometrium and myometrium during the menstrual cycle.

    Pure osteosarcoma arising from the uterus is extremely rare. Only 15 cases of this type of cancer have been reported to date. Most patients showed local or lung metastasis early after surgery and died within a year of treatment initiation, regardless of multimodality therapy, indicating that this tumor is aggressive with a poor prognosis. Herein, we report the first clinical experience treated with a combination of docetaxel and gemcitabine for local and lung metastasis from primary osteosarcoma of the uterus. Although the disease was considered stable after three cycles of treatment, new metastatic lesions appeared in the lungs after six cycles. The patient was asymptomatic for 13 months; however, she died two months after symptom recurrence. Our case demonstrates that a combined regimen of docetaxel and gemcitabine may be a sound therapeutic option to control primary osteosarcoma of the uterus. © 2016 Japan Society of Obstetrics and Gynecology.

    Purpose: In patients with uterine cervical cancer, pretreatment recognition of uterine extension is crucial in treatment decision-making for fertility-sparing surgery and for target delineation in radiotherapy. Although MRI is generally considered the most reliable method, its value for detecting involvement of the uterine internal os is unclear. Methods: Medline, Embase and Cochrane databases were systematically searched (January 1997–December 2012) for MRI studies that measured the accuracy of involvement of the uterine internal os compared to histopathology as reference standard in patients with uterine cervical cancer. Data were assessed using the QUADAS tool. Accuracy concerned either involvement (yes/no) of the uterine internal os, or measuring invasion distance toward the uterine corpus. Results: Two retrospective and two prospective studies described 366 patients diagnosed with uterine cervical cancer FIGO stage IIB or below, in whom 64 (17%) had uterine internal os involvement. For three studies the summary estimates of specificity, sensitivity, negative predictive value (NPV), positive predictive value (PPV), and accuracy were 91%, 97%, 99%, 79% and 95%, respectively; one study had an area under the curve (AUC) of 0.8. Conclusion: MRI has a high level of accuracy; however, data are limited and for validation a large prospective study is needed that compares actual measurements on MRI with histopathological examination.

We emphasize on uterine's cancer aetiology according to the dominant in antiquity humoural theory, on its surgical treatment suggested by Soranus of Ephesus, and in the vivid description provided by Aretaeus of Cappadocia. During that period, uterine cancer was considered as an incurable and painful malignancy and its approach was mainly palliative.

    It is currently believed that cancer procoagulant (CP), an enzymatic protein, is a product of malignant neoplastic cells. The present study was designed to test whether it is also synthesized by benign neoplastic cells, namely uterine leiomyomas. We determined the activity of CP in the blood serum of women with uterine leiomyomas (N = 24), normal women (N = 15), and genital cancer patients (N = 6) by the coagulative method according to Gordon and Benson. Also, the CP activity in 10% tissue homogenates of uterine leiomyomas, normal uterine muscle and tissues of cervical and endometrial carcinoma was determined by the chromogenic method according to Colucci et al. The mean CP activity in the sera of women with uterine leiomyomas was 181.1 seconds (s) +/- 19.9 s, in healthy women--293.2 s +/- 33.8 s, and in genital cancer patients--78.8 +/- 18.5 s (all differences: p < 0.001). Similarly, in homogenates of uterine leiomyomas the CP activity was 19.6 +/- 3.8 nmoles pNa/ml, in normal uterine muscle it was 13.2 +/- 2.2 nmoles pNa/ml, and in cancerous tissue--28.0 +/- 6.6 nmol pNa/ml (all values being significantly different from each other). There was a strong correlation (r = -0.8122; p < 0.001) between the CP activity in uterine leiomyomas and serum activity, suggesting that the source of the serum CP activity was from the leiomyoma. The coagulation time of 120 to 240 s by the Gordon and Benson method supported the diagnosis of uterine leiomyoma, and a value below 120 s--the suspicion of genital cancer. Uterine leiomyomas, representing benign genital neoplasia, synthesize CP and are the likely origin of CP activity in blood, as has been described for malignant tumors, but to a lesser degree. There may be a role for CP as a tumor marker of genital neoplasia.

    Byzantine physicians recognized uterine cancer as a distinct disease and tried to suggest a therapeutic approach. The work of Oribasius, Aetius of Amida, Paul of Aegina, Cleopatra Metrodora and Theophanes Nonnus reflects the Hippocratic-Galenic scientific ideas as well as their own concept on this malignancy. According to their writings uterine cancer was considered an incurable disease and its treatment was based mainly on palliative herbal drugs.

    Cervix cancers declined in most developed countries in recent years, but remain, the third worldwide leading cause of cancer death in women. A precise staging, based on clinical exam, an abdominal and pelvic MRI, a possible PET-CT and a possible lymph node sampling is necessary to adapt the best therapeutic strategy. In France, the treatments of tumors of less than 4 cm without nodal involvement are often based on radiotherapy followed by surgery and, whereas tumors larger than 4 cm and involved nodes are treated with concurrent chemoradiotherapy. Based on an illustrated clinical case, indications, delineation, dosimetry and complications expected with radiotherapy are demonstrated. (authors)

    To establish the association between high-grade intraepithelial lesions and cervical-uterine-cancer, and the infection by human papillomavirus, genetic antecedents, socioeconomics, sexual behavior and gynecology and obstetrics factors in women of the State of Nayarit, Mexico. With a case-control design were studied 66 cases of high-grade intraepithelial lesions and cervical-uterine-cancer, and 132 controls. The information upon the risk factors was obtained by the application of a structured questionnaire. Polymerase Chain Reaction executed the virus identification. In the statistical analysis the association was obtained by odds ratio. The statistical significance was evaluated by the chi-square-Fisher and Student t tests, and multivariate logistic regression was used to explain the factors' influence. In women with high-risk squamous intraepithelial lesions and cervical-uterine-cancer, the most frequently high-risk human papillomavirus found were: 18, 35, 58, 16, 31, 33 and 51. Familial data of cervical-uterine-cancer, socioeconomic level, number of sexual partners, data of sexual transmitted diseases, and infection due to human papillomavirus 18 and 35 are the factors related to high-risk squamous intraepithelial lesions and cervical-uterine-cancer.

    Full Text Available Abstract We present a 69-year-old woman with a chief complaint of postmenopausal bleeding. She was diagnosed as having an endometrioid adenocarcinoma by biopsy, and underwent a total abdominal hysterectomy. At the time of surgery, granulation tissue-like nodules were found on the peritoneal serosa of the uterus. In the intraoperative cytology of peritoneal washing, atypical cells were noted. The intraoperative frozen section of the peritoneal nodule revealed granulation tissue with proliferating mesothelial cells. Microscopic examination of the permanent section showed keratin granulomas without viable adenocarcinoma cells on the serosal surface of the ovaries, fallopian tubes and broad ligaments. Postoperative chemotherapy was administered. She has been alive with no evidence of recurrence for 6 months postoperatively. It should be noted that the prognosis of cases in peritoneal keratin granuloma without viable cancer cells is favorable, and that the histological examination is essential for its diagnosis.

    In this work, we report on a relationship between urinary selenium and the development of cervical uterine cancer. A simple chemical method was developed to concentrate trace amounts of selenium from relatively large urine samples by use of small activated carbon filters. When these filters are irradiated with thermal neutrons, selenium can be determined either by 77mSe (t1/2 = 17.5 s) or 75Se (t1/2 = 120 d). In this article, we report the results for 82 urine samples from women with cervical uterine cancer in several stages of development and from healthy controls. These results show a statistically significant increase of selenium excretion in cancer patients as compared to controls. Urinary selenium excretion is highest for patients in the intermediate stages of the disease.

    The purpose of this retrospective study was to evaluate the efficacy and feasibility of short-course hypofractionated radiotherapy (RT) for the palliation of uterine cervical cancer. Seventeen patients with cancer of the uterine cervix, who underwent palliative hypofractionated 3-dimensional conformal radiotherapy between January 2002 and June 2012, were retrospectively analyzed. RT was delivered to symptomatic lesions (both the primary mass and/or metastatic regional lymph nodes). The total dose was 20 to 25 Gy (median, 25 Gy) in 5 Gy daily fractions. The median follow-up duration was 12.2 months (range, 4 to 24 months). The median survival time was 7.8 months (range, 4 to 24 months). Vaginal bleeding was the most common presenting symptom followed by pelvic pain (9 patients). The overall response rates were 93.8% and 66.7% for vaginal bleeding control and pelvic pain, respectively. Nine patients did not have any acute side effects and 7 patients showed minor gastrointestinal toxicity. Only 1 patient had grade 3 diarrhea 1 week after completion of treatment, which was successfully treated conservatively. Late complications occurred in 4 patients; however, none of these were of grade 3 or higher severity. Short-course hypofractionated RT was effective and well tolerated as palliative treatment for uterine cervical cancer.

    Verbal autopsy (VA) is a standardized method for investigating causes of death. Currently, the Mexican Ministry of Health uses officially VA to reconstruct the history of women who died of cervical cancer. to describe the findings of the VA of dead women due to cervical cancer in Tijuana, Baja California, Mexico. All death certificates issued in the years 2001 and 2001 in which cervical cancer was the main cause of death were reviewed. The VA included forty-five questions exploring six domains: subjects' personal information, sociodemographic characteristics, history of the disease, timely medical care, risk factors, affiliation to social security, and information registered in the death certificate. Seventy-nine women out of 97 had VA. The mean age was 54 years; 33% completed elementary school; 32% had smoking history; 50% had more than five pregnancies; 42% started sexual activity before the age of 17, 52% had had 2 to 3 sexual partners. 60% had Papanicolau test; 90% knew about their condition; 86% received medical care and 34% knew they had cancer one year before death. Verbal autopsy revealed that 40% of women who died of cervical cancer did not have Papanicolau test before being diagnosed.

    Full text: The objective of this study was to evaluate the levels of trace elements in blood sera of uterine cervix cancer patients, analyze their alteration with respect to healthy controls, ascertain the role played by them in the initiation, promotion and inhibition of cancer, and identify the best predictors amongst these for disease occurrence and progression. Moreover, the variation of trace elemental content in the sera of cervix cancer patients with the clinical stage of disease and with therapy was also studied. Particle induced X-ray emission (PIXE), a well established method for elemental analysis, was used in this work to identify and quantify trace elements in the blood sera of uterine cervix cancer subjects and healthy control subjects. The PIXE measurements were carried out using 2.5 MeV collimated proton beam from the 3 MV Tandem Pelletron Accelerator at lon Beam Laboratory, Institute of Physics, Bhubaneswar, India. Among all the trace elements identified in this work, statistically significant alterations in serum levels of copper, zinc, and selenium were observed among the various studied groups. The observed alterations are discussed with respect to the possible mechanisms by which these elements might influence the carcinogenic process. (author)

    Uterine cervical cancer still remains an important socioeconomic issue because it largely affects women of reproductive age. Prognosis is highly depended on extent of the disease at diagnosis and, therefore, accurate staging is crucial for optimal management. Cervical cancer is clinically staged, according to International Federation of Gynecology and Obstetrics guidelines, but, currently, there is increased use of cross sectional imaging modalities [computed tomography (CT), magnetic resonance imaging (MRI), positron emission tomography-CT (PET-CT)] for the study of important prognostic factors like tumor size, parametrial invasion, endocervical extension, pelvic side wall or adjacent/distal organs involvement and lymph node status. Imaging indications also include cervical cancer follow-up, evaluation of tumor response to treatment and selection of suitable candidates for less radical surgeries like radical trachelectomy for fertility preservation. The preferred imaging method for local cervical cancer evaluation is MRI; CT is equally effective for evaluation of extrauterine spread of the disease. PET-CT shows high diagnostic performance for the detection of tumor relapse and metastatic lymph nodes. The aim of this review is to familiarize radiologists with the MRI appearance of cervical carcinoma and to discuss the indications of cross sectional imaging during the course of the disease in patients with cervical carcinoma.

    By means of re-irradiation using pepleomycin suppository in uterine cavity, we attained local control for one patient who had local recurrence in uterine cavity and suffered from uterine fluor in which viable cancer cells were confirmed. We were enlightened by this therapeutic experience, so we attempted combination therapy using pepleomycin suppositories to supplement intra-cavitary irradiation, for the 11 selected patients who were suffering from uterine fluor. We investigated the treatment results in 7 patients of stage III out of 11 patients (of all stages), in comparison with 13 patients of stage III who were treated by irradiation alone. Consequently, these treatment results were approximately equivalent, and the incidence of sigmoid complications could be decreased. Side effects which were followed by the combination therapy were not serious, and so we believe that pepleomycin suppository is a simple method and valuable to supplement radiation therapy of uterine cervical cancer.

    Purpose : The aim of this study is to analyze the survival rate, treatment failure and complication of radiation therapy alone in stage III uterine cervical cancer. Materials and Methods : From January 1980 through December 1985, 227 patients with stage II uterine cervical cancer treated with radiation therapy at Kosin Medical Center were retrospectively studied. Among 227 patients, 72 patients(31.7%) were stage IIIa, and 155 patients(68.3%) were stage IIIb according to FIGO classification. Age distribution was 32-71 years(median: 62 years). Sixty nine patients(95.8%) in stage IIIa and 150 patients(96.8%) in stage IIIb were squamous cell carcinoma. Pelvic lymph node metastasis at initial diagnosis was 8 patients (11.1%) in stage IIIa and 29 patients(18.7%) in stage IIIb. Among 72 patients with stage IIIa, 36 patients(50%) were treated with external radiation therapy alone by conventional technique (180-200 cGy/fr). And 36 patients(50%) were treated with external radiation therapy with intracavitary radiotherapy(ICR) with Cs137 sources, and among 155 patients with stage IIIb, 80 patients(51.6%) were treated with external radiation therapy alone and 75 patients(48.4%) were treated with external radiation therapy with ICR. Total radiation doses of stage IIIa and IIIb were 65-105 Gy(median : 78.5 Gy) and 65-125.5 Gy (median :83.5 Gy). Survival rate was calculated by life-table method. Results : Complete response rates were 58.3% (42 patients) in state IIIa and 56.1%(87 patients) in stage Iiib. Overall 5 year survival rates were 57% in stage IIIa and 40% in stage IIIb. Five year survival rates by radiation technique in stage IIIa and IIIb were 64%, 40% in group treated in combination of external radiation and ICR, and 50%, 40% in the group of external radiation therapy alone(P=NS). Five year survival rates by response of radiation therapy in stage IIIa and IIIb were 90%, 66% in responder group, and 10%, 7% in non-responder group (P<0.01). There were statistically no

    Full Text Available Towards the end of the past century, cancer of the corpus uteri achieved the status of leading gynecologic cancer not only in developed countries, but also in Third World countries. The leading determinants of prognosis and treatment policy are tumor extent and grade at diagnosis. It is important to search for the informative and significant indicators of biological tumor activity, which are determined by pre- and postoperative mini-invasive laboratory studies, the combination of which could additionally judge the extent and grade of a tumor. At present, there are no significant tumor markers for the screening for and evaluation of progressive cancer of the corpus uteri, which would have a high specificity and sensitivity although their search is constantly underway worldwide.

    We report on an illuminated, low-cost (Rs 1500 (US$ 36)) magnifying device (Magnivisualizer) for detecting precancerous lesions of the uterine cervix. A total of 403 women attending a maternal and child health care clinic who had abnormal vaginal discharge and related symptoms were referred for detailed pelvic examination and visual inspection by means of the device after the application of 5% (v/v) acetic acid. Pap smears were obtained at the same time. The results were compared with those obtained using colposcopy and/or histology. The Magnivisualizer improved the detection rate of early cancerous lesions from 60%, for unaided visual inspection, to 95%. It also permitted detection of 58% of cases of low-grade dysplasia and 83% of cases of high-grade dysplasia; none of these cases were detectable by unaided visual inspection. For low-grade dysplasia the sensitivity of detection by means of the Magnivisualizer was 57.5%, in contrast with 75.3% for cytological examination. However, the two methodologies had similar sensitivities for higher grades of lesions. The specificity of screening with the Magnivisualizer was 94.3%, while that of cytology was 99%. The cost per screening was approximately US$ 0.55 for the Magnivisualizer and US$ 1.10 for cytology.

    To avoid improper tumor volume contouring in radiation therapy (RT) and other invasive procedures, we report a case of uterine adenomyosis showing increased 18F-fl uorodeoxyglucose (FDG) uptake on positron emission tomography (PET)/computed tomography (CT) mimicking malignant tumor in a 44-year-old woman during concurrent chemoradiation therapy (CCRT) for uterine cervical cancer. The adenomyosis was not associated with her menstrual cycle or with normal endometrium uptake, and it resolved one month after completion of RT. This case indicates that uterine adenomyosis in a premenopausal woman may show false positive uptake of 18FDG-PET/CT associated with CCRT.

    To design clear guidelines for the staging and follow-up of patients with uterine cervical cancer, and to provide the radiologist with a framework for use in multidisciplinary conferences. Methods: Guidelines for uterine cervical cancer staging and follow-up were defined by the female imaging subcommittee of the ESUR (European Society of Urogenital Radiology) based on the expert consensus of imaging protocols of 11 leading institutions and a critical review of the literature. The results indicated that high field Magnetic Resonance Imaging (MRI) should include at least two T2-weighted sequences in sagittal, axial oblique or coronal oblique orientation (short and long axis of the uterine cervix) of the pelvic content. Axial T1-weighted sequence is useful to detect suspicious pelvic and abdominal lymph nodes, and images from symphysis to the left renal vein are required. The intravenous administration of Gadolinium-chelates is optional but is often required for small lesions (<2 cm) and for follow-up after treatment. Diffusion-weighted sequences are optional but are recommended to help evaluate lymph nodes and to detect a residual lesion after chemoradiotherapy. Expert consensus and literature review lead to an optimized MRI protocol to stage uterine cervical cancer. MRI is the imaging modality of choice for preoperative staging and follow-up in patients with uterine cervical cancer. (orig.)

    Brain metastasis from uterine cervical cancer is rare, with an incidence of 0.5%, and usually occurs late in the course of the disease. We report a case of uterine cervical cancer with brain metastasis as the initial site of presentation. A 50-year-old woman with headache, vertigo, amnesia and loss of appetite was admitted for persistent vomiting. Contrast enhanced computed tomography showed a solitary right frontal cerebral lesion with ring enhancement and uterine cervical tumor. She was diagnosed with uterine cervical squamous cell carcinoma with parametrium invasion and no other distant affected organs were detected. The cerebral lesion was surgically removed and pathologically proved to be metastasis of uterine cervical squamous cell carcinoma. The patient underwent concurrent chemoradiotherapy, followed by cerebral radiation therapy, but multiple metastases to the liver and lung developed and the patient died 7 months after diagnosis of brain metastasis. © 2015 The Authors.

    Mesonephric adenocarcinomas are rare neoplasms that most commonly arise in the uterine cervix and exceptionally rarely in the uterine corpus. Although the morphologic features of these neoplasms are well described, there has been relatively limited investigation of the immunoprofile. We report a series of 8 mesonephric adenocarcinomas arising in the uterine cervix (7 cases) and corpus (1 case) and undertake a comprehensive immunohistochemical analysis. This includes markers that have not been investigated previously in mesonephric adenocarcinomas but that are commonly used in gynecologic pathology and may be undertaken when other, mainly Mullerian, adenocarcinomas are considered in the differential diagnosis. Linear array human papillomavirus (HPV) genotyping was also performed. Our results broadly confirm the immunohistochemical profile demonstrated in previous studies with the majority of mesonephric adenocarcinomas staining positively with CD10 (6 of 8), epithelial membrane antigen (8 of 8), vimentin (8 of 8), and calretinin (7 of 8). Estrogen receptor was positive in 2, carcinoembryonic antigen in 3, and inhibin in 4 cases. p16 was positive in 5 cases (1 diffuse and strong), despite all being HPV negative (in 1 case, there was insufficient DNA for HPV analysis). Novel findings in our study were the demonstration of nuclear positivity with PAX8 and HMGA2 in 7 cases, CA125 immunoreactivity in all 8 cases, and TTF1 and hepatocyte nuclear factor 1-β staining in 3 cases. As PAX8, CA125, HMGA2, and hepatocyte nuclear factor 1-β are commonly positive in a variety of Mullerian adenocarcinomas arising in the female genital tract, this may result in diagnostic confusion. All cases were WT1 negative.

    Objective The incidence for uterine cancers has been reported to be higher among white women, whereas mortality is higher among black women. Reasons for the higher mortality among black women are not completely understood. The aim of our study is to examine the relationship between race/ethnicity, histopathologic subtype, and survival in uterine cancer. Methods We abstracted socio-demographic, treatment, and survival data for all women who were diagnosed with uterine cancer at Montefiore Medical Center from January 1999 through December 2009. Pathology records were reviewed. Results 984 patients were identified. Racial/ethnic distribution was 382 (39%) white, 308 (31%) black, 232 (24%) Hispanic, and 62 (6.3%) other races, mixed, or unknown. 592 (60%) patients had endometrioid histology. Blacks were much more likely than whites to have non-endometrioid histologies (p<0.001), including papillary serous, carcinosarcoma, and leiomyosarcoma. Blacks and Hispanics were at least as likely as whites to receive either chemotherapy or radiation therapy. The hazard ratio for death for black versus white patients was 1.94 (p<0.001) when all histological subtypes were included. The hazard ratio for Hispanics for death was 1.2 (p=0.32) compared to whites. However, when patients were divided into endometrioid and non-endometrioid histological subtypes, there was no significant difference in survival by race/ethnicity. Conclusion Black patients with uterine cancer are much more likely to die and are much more likely to have non-endometrioid histologies than white patients. There are no differences in survival among white, black, or Hispanic women with uterine cancer, after control for histological subtype. PMID:22940487

    Uterine cervical cancer is still the second largest cancer in women worldwide, despite of effective screening methods. Radiotherapy is used to treat all the stages of cervical cancer and more than 60% of cervical cancer patients receive radiotherapy. New therapeutic targets or approaches are needed to further increase the results of radiotherapy. In the present study, we demonstrated the radiation induced overexpression and nuclear export of FTS in cervical cancer cells. Furthermore, we showed that silencing of FTS expression with FTS shRNA enhanced radiosensitivity of cervical cancer cells, induced cell cycle arrest and apoptosis FTS is involved in radioresistance of cervical cancer. Targeted inhibition of FTS can shutdown the key elemental characteristics of cervical cancer and could lead to an effective therapeutic strategy.

Material and methods: All consecutive uterine cervical cancer patients who were treated by primary radiation therapy were reviewed, and those who were treated by ISBT were further investigated for clinical outcomes and related toxicities. Results : From December 2008 to October 2014, 209 consecutive uterine cervical cancer patients were treated with primary radiation therapy. Among them, 142 and 42 patients were treated by intracavitary and hybrid brachytherapy, respectively. Twenty-five patients (12% were treated by high-dose-rate (HDR-ISBT. Five patients with distant metastasis other than para-aortic lymph node were excluded, and 20 patients consisted of the analysis. Three-year overall survival (OS, progression-free survival (PFS, and local control (LC rate were 44.4%, 38.9%, and 87.8%, respectively. Distant metastasis was the most frequent site of first relapse after HDR-ISBT. One and four patients experienced grade 3 and 2 rectal bleeding, one grade 2 cystitis, and two grade 2 vaginal ulcer. Conclusions : Feasibility and favorable local control of interstitial brachytherapy for locally advanced cervical cancer was demonstrated through a single institutional experience with a small number of patients.

    Increasingly, robotic surgery is being used for total hysterectomy, bilateral salpingo-oophorectomy, and lymph node dissection for uterine cancer. The purpose of this study was to compare the costs and complications among women undergoing robotic and laparoscopic hysterectomy for uterine cancer. We carried out a cohort study using the Nationwide Inpatient Sample (NIS) database between 2008 and 2012 on all women diagnosed with uterine cancer, classifying women as either laparoscopically or robotically treated, excluding laparotomies or vaginal approaches. Logistic regression analyses were used to evaluate the adjusted effect of surgical approach on complication rates. There were 10,347 women who underwent hysterectomies for uterine cancer either laparoscopically (39%) or robotically (61%). The rate of robotic surgery consistently increased over the 5 year period. Women undergoing robotic surgery had more comorbid conditions (diabetes, hypertension, cardiovascular disease, renal disease, obesity or morbid obesity, and pulmonary disease). In adjusted analyses, women undergoing robotic surgery were more likely to have a lymph node dissection (73.01% vs 66.04%; P laparoscopic surgery. The composite endpoint of any complication was similar between both cohorts (20.56% robotic vs 21.00% laparoscopy). In overall and subset analyses, robotic surgery was more costly, with median charges of $38,161.00 compared with $31,476.00 in those undergoing laparoscopic surgery (P < .0001). Despite the considerably greater burden of comorbidities in those undergoing robotic surgery compared with laparoscopy, the former have shorter hospital admissions, a greater rate of lymph node dissection, and similar postoperative morbidity and mortality, albeit at greater total cost.

Methods: A retrospective, descriptive epidemiological analysis was conducted of all the corpus uteri cancer cases recorded in the Saudi Cancer Registry between January 2001 and December 2008. The statistical analyses were performed using descriptive statistics, analysis of variance, Poisson regression, and a simple linear model. Results: A total of 1,060 corpus uteri cancer cases were included. Women aged 60–74 years of age were most affected by the disease. The region of Riyadh in Saudi Arabia had the highest overall ASIR, at 4.4 cases per 100,000 female patients, followed by the eastern region, at 4.2, and Makkah, at 3.7. Jazan, Najran, and Qassim had the lowest average ASIRs, ranging from 0.8 to 1.4. A Poisson regression model using Jazan as the reference revealed that the corpus uteri cancer incidence rate ratio was significantly higher for the regions of Makkah, at 16.5 times (95% confidence interval [CI]: 8.0–23.0, followed by Riyadh, at 16.0 times (95% CI: 9.0–22.0, and the eastern region, at 9.9 times (95% CI: 5.6–17.6. The northern region experienced the highest changes in ASIRs of corpus uteri cancer among female Saudi patients between 2001 and 2008. Conclusion: There was a slight increase in the crude incidence rates and ASIRs for corpus uteri cancer in Saudi Arabia between 2001 and 2008. Older Saudi women were most affected by the disease.

    In vitro studies showed that lipophilic statins inhibit cell growth, adhesion, and invasion and induce apoptosis in cancer cell lines. In uterine cervical cancer, several important factors including age, stage, anemia, lymphovascular invasion, lymph node metastases, and parametrial spread were known to significantly predict survival. We investigated whether statin therapy as a prognostic factor would significantly predict survival in cervical cancer. Patients with stages IB to IV cervical cancer who received radical hysterectomy and/or para-aortic lymph node dissection were included. The statin-use group was identified as patients who were continuously prescribed with lipophilic statins from prediagnostic period of the cancer. The baseline characteristics of both statin-use group and control group were comparable. During a median follow-up of 36.6 months, progression-free survival and overall survival of the statin-use group were significantly higher than the control group (P < 0.001 and P = 0.004, respectively). In multivariate analysis, the statin-use group had an independent prognostic significance compared with other prognostic factors (progression-free survival: hazards ratio = 0.062, 95% confidence interval = 0.008-0.517, P = 0.010; overall survival: hazards ratio = 0.098, 95% confidence interval = 0.041-0.459, P = 0.032). In the present study, continuous lipophilic statin therapy from the prediagnostic period of uterine cervical cancer could reflect favorable outcome, independently.

    Recent changes in the lifestyle of young women have led to an increase in the rate of uterine cervical cancer. We investigated the clinicopathological characteristics of uterine cervical cancer in young women, and examined the expression of vascular endothelial growth factor (VEGF), matrix metalloproteinases (MMPs) and cyclooxygenase-2 (COX-2). Tumor samples from 439 patients with uterine cervical cancer, who were initially treated at Osaka City University Medical School Hospital, Japan between 1995 and 2004, were stained immunohistochemically. The patients were classified into two groups according to age at onset: group Y included women aged or =36 years. Group Y had more cases of squamous cell carcinoma, while group O had more advanced cases (Pcervical cancer in young women.

    To evaluate the outcomes of adjuvant radiotherapy (RT) and to analyze prognostic factors of survival in the International Federation of Gynecology and Obstetrics (FIGO) IB-IIA uterine cervical cancer. We retrospectively reviewed the medical records of 148 patients with FIGO IB-IIA uterine cervical cancer who underwent surgery followed by adjuvant RT at the Yonsei Cancer Center between June 1997 and December 2011. Adjuvant radiotherapy was delivered to the whole pelvis or an extended field with or without brachytherapy. Among all patients, 57 (38.5%) received adjuvant chemotherapy either concurrently or sequentially. To analyze prognostic factors, we assessed clinicopathologic variables and metabolic parameters measured on preoperative 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). To evaluate the predictive performance of metabolic parameters, receiver operating characteristic curve analysis was used. Overall survival (OS) and disease-free survival (DFS) were analyzed by the Kaplan-Meier method. The median follow-up period was 63.2 months (range, 2.7 to 206.8 months). Locoregional recurrence alone occurred in 6 patients, while distant metastasis was present in 16 patients, including 2 patients with simultaneous regional failure. The 5-year and 10-year OSs were 87.0% and 85.4%, respectively. The 5-year and 10-year DFSs were 83.8% and 82.5%, respectively. In multivariate analysis, pathologic type and tumor size were shown to be significant prognostic factors associated with both DFS and OS. In subset analysis of 40 patients who underwent preoperative PET/CT, total lesion glycolysis was shown to be the most significant prognostic factor among the clinicopathologic variables and metabolic parameters for DFS. Our results demonstrated that adjuvant RT following hysterectomy effectively improves local control. From the subset analysis of preoperative PET/CT, we can consider that metabolic parameters may hold prognostic significance

    Magnetic resonance imaging (MRI) was performed in 62 patients with uterine cervical cancer and the preoperative MRI findings were compared with the pathological findings following surgery. The surgical stages of 62 patients were 2 at stage 0, 18 at stage Ia, 19 at stage Ib, 9 at stage IIa, 11 at stage IIb, 2 at stage IIIa, and 1 at stage IIIb. The MRI findings in the present study included: (1) the existence of a high intensity area (HIA) in the uterine cervix or minimum thickness of residual normal cervical tissue, (2) necrotic cavity, (3) pyometra, (4) irregular margin of the cervix, (5) parametrial invasion, (6) vaginal invasion, (7) bladder invasion, and (8) lymph node enlargement. No HIA was observed in any patient with stage 0 or stage Ia, in 8 patients with stage Ib, and in 2 patients with stage IIa, while all patients with cancer tissues greater than 10 mm in diameter had a HIA. In 39 patients in whom hysterectomy was undergone without conization, the findings of MRI correlated significantly (r=0.929, p<0.001) with the minimum thickness of residual normal cervical tissue by the pathological measurement. When the irregular margin of the cervix was regarded as a disruption of the cervical myo-metrium by cancer tissue, accuracy was 87%. Furthermore, the degrees of accuracy for parametrial invasion, vaginal invasion and bladder invasion were 92%, 90% and 94%, respectively. When lymphnodes greater than 15 mm in diameter were regarded as a positive in MRI, accuracy was 88%. The present results indicate that MRI is clinically effective in preoperatively evaluating the extension of uterine cervical cancer. (author).

    Full Text Available Endometrial cancer is the most common female genital tract malignancy in the United States. Type I endometrial cancer is usually diagnosed at an early stage, and has a good prognosis. Type II is very aggressive, and is responsible for most uterine cancer relapses and deaths. Uterine serous adenocarcinomas (USC constitute the majority of Type II variants. They have a higher propensity for lymph node and distant metastases. They are frequently aneuploid and associated with p53 mutations. erbB2 overexpression in USC has been described. The incidence, which is higher in African Americans, ranges from 18–80%. erbB2 overexpression was found to be associated with higher stage, chemoresistance, and worse survival. Trastuzumab a humanized mAb was approved by the FDA for treatment of breast cancers that overexpress erbB2 in combination with standard chemotherapy. Evidence of trastuzumab activity in USC has been reported in vitro, as well as in case reports of advanced and recurrent cases. Promising results were obtained in these heavily pretreated patients either with trastuzumab alone or in combination with chemotherapy. This supports the hypothesis that trastuzumab may very well be an attractive and viable treatment option for advanced stage USC tumors that overexpress the erbB2, and is worthy of further study.

    The Okinawa Islands located in the southern-most part of Japan were under U.S. administration from 1945 to 1972. During that time, fluoride was added to the drinking water supplies in most regions. The relationship between fluoride concentration in drinking water and uterine cancer mortality rate was studied in 20 municipalities of Okinawa and the data were analyzed using correlation and multivariate statistics. The main findings were as follows. (1) A significant positive correlation was found between fluoride concentration in drinking water and uterine cancer mortality in 20 municipalities (r = 0.626, p divorce rate, this association was considerably significant. (3) Furthermore, the time trends in the uterine cancer mortality rate appear to be related to changes in water fluoridation practices.

    The case of a patient diagnosed with uterine cervix cancer is presented as an example of the clinical application of the radiobiological compensation method implemented at Centro Estatal de Cancerología de Durango. Radiotherapy treatment was initially modified to compensate for the chemotherapy component and, as medical complications arose during treatment delivery resulting in an 18 days gap, new compensation followed. All physical and radiobiological assumptions to calculate the Biologically Effective Dose in the external beam and brachytherapy parts of the treatment are presented. Good local control of the tumor was achieved, the theoretical tolerance limits for the organs at risk were not surpassed and the patient manifested no extensive morbidity.

She was admitted to our hospital complaining of abdominal pain in February, 1996. Contrast-enhanced computed tomographic scan and cystography showed leakage of contrast medium around the bladder. We diagnosed her with spontaneous vesical rupture, and performed conservative therapy. Two months later, she was re-admitted with recurrent vesical rupture. We again performed conservative therapy. We consider that conservative therapy can be indicated for spontaneous vesical rupture with good general condition and no severe urinary tract infection. (author)

    In intensity modulated radiation therapy (IMRT) of cervical cancer, uterine motion can be larger than cervix motion, requiring a larger clinical target volume to planning target volume (CTV-to-PTV) margin around the uterine fundus. This work simulates different motion models and margins to estimate the dosimetric consequences. A virtual study used image sets from ten patients. Plans were created with uniform margins of 1 cm (PTV{sub A}) and 2.4 cm (PTV{sub C}), and a margin tapering from 2.4 cm at the fundus to 1 cm at the cervix (PTV{sub B}). Three inter-fraction motion models (MM) were simulated. In MM1, all structures moved with normally distributed rigid body translations. In MM2, CTV motion was progressively magnified as one moved superiorly from the cervix to the fundus. In MM3, both CTV and normal tissue motion were magnified as in MM2, modeling the scenario where normal tissues move into the void left by the mobile uterus. Plans were evaluated using static and percentile DVHs. For a conventional margin (PTV{sub A}), quasi-realistic uterine motion (MM3) reduces fundus dose by about 5 Gy and increases normal tissue volumes receiving 30-50 Gy by {approx}5%. A tapered CTV-to-PTV margin can restore fundus and CTV doses, but will increase normal tissue volumes receiving 30-50 Gy by a further {approx}5%.

    We examined 19 patients with post-irradiation intestinal injury in the uterine cervix cancer for 12 years between 1985 and 1996. We discuss the usefulness and complications of surgery, mainly colostomy. The patients aged from 36 to 80 (average age 61) were treated, and their disease states were 12 cases of rectovaginal fistula, 2 of small intestinal fisfula, 1 of rectum posterior membranous fistula, 3 of proctostenosis, and 14 of proctitis with hemorrhage (including duplication). Surgical methods used were 18 cases of colostomy (2 cases were treated under peritoneum mirror) and 2 of enterocolostomy (including duplication). Eleven out of 19 patients who underwent surgery are alive now. Generally the post-irradiation intestinal injury was intractable, and the method of treatments were limited due to the coexistence of various diseases. The colostomy is safe and less invasive. Therefore patients with uterine cervix cancer having various complications can obtain high quality of life (QOL) such as the improvement of anemia and/or the increase of digestion by the colostomy.

    The aim was to evaluate surgical treatment of newly diagnosed uterine cancer in a Swedish population. Data in the GynOp registry from 2008 to 2014 were analyzed. In total, 3443 cases were included: 430 (12%) were robotic-assisted laparoscopic, 272 (8%) laparoscopic, and 2741 (80%) abdominal operations. There was an increasing trend in minimally invasive surgery from 2008 to 2014 (41%). Women with lymph nodes removed in the robotic-assisted laparoscopic group experienced less blood loss (mean 105 vs. 377 mL), shorter length of hospital stay (2.4 vs. 4.1 days), and fewer days to normal activities of daily living (6.5 vs. 12.7 days) (all p laparoscopic (mean 26.0) group, but the number of women with lymph node metastases did not differ, totaling 211/960 (21.9%; 95% CI 19.4-24.7%). Isolated para-aortic lymph node metastases were found in 3.9% (95% CI 2.4-5.6%) of women. Minimally invasive surgery in uterine cancer patients reduces days to normal activities of daily living, number of days to return to work, length of hospital stay, and blood loss in patients without and with lymph node dissection and in obese patients. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

    Full Text Available Peritoneal keratin granulomatosis is a rare condition included under granulomatous lesions of the peritoneum. It can be secondary to neoplasms of the female genital tract and can mimic carcinomatosis intraoperatively. A case of a 40-year-old woman with a history of polycystic ovaries and a chief complaint of vaginal bleeding is presented. She was diagnosed with endometrioid adenocarcinoma with squamous differentiation in endometrial curettings. Intraoperatively, many peritoneal nodules were found, interpreted as peritoneal carcinomatosis. The woman underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy, omentectomy, bilateral pelvic lymphadenectomy, and appendicectomy. Multiple biopsies were taken, as well as peritoneal washings. Microscopic examination revealed multiple keratin granulomas on the serosal surface of the ovaries, fallopian tubes, appendix, and omentum. Lymph node metastasis was not found. Peritoneal keratin granulomas (PKGs have been reported in cases of endometrioid adenocarcinoma with squamous differentiation of the uterine corpus, ovary, and atypical adenomyoma. It should be noted that the prognosis of cases of peritoneal keratin granulomas without viable tumor cells is favourable and that the histologic examination is essential for its diagnosis. We report a case of PKG in a patient with endometrial carcinoma with squamous differentiation, being the first in a woman with polycystic ovaries.

    Pelvic inflammatory disease (PID) is characterized by infection and inflammation of the upper genital tract in women and is associated with health sequelae. We used a nationwide population-based retrospective cohort study to explore the relationship between PID and the subsequent development of gynecological cancers including ovarian, breast or uterine cancer. We identified subjects diagnosed with PID between January 1(st), 2000 and December 31(st), 2002 in the Taiwan National Health Insurance Research Database. A comparison cohort constructed for patients without PID were matched according to age and sex. All PID patients and control groups were observed until diagnosed with ovarian, breast or uterine cancer, or until death, withdrawal from the NHI system, or until December 31(st), 2009. The PID cohort consisted of 32,268 patients, and an equal number of matched controls without PID. The adjusted hazard ratio (HR) of ovarian, breast or uterine cancer in subjects with PID were: HR 1.326 (95 % confidence interval: 0.775-2.269), HR: 1.039 (95 % confidence interval: 0.862-1.252), and HR: 1.439 (95 % confidence interval: 0.853-2.426) respectively in comparison with controls during follow-up. This large nationwide population-based cohort study suggests that there is no increased risk for ovarian, breast or uterine cancer among women who have PID compared to a matching population.

The results obtained demonstrated that the anabolic steroid (1) enhanced the activity of macrophages and cell-mediated immune activity, (2) reduced the incidence of post-operative infection, (3) reduced pose-operative loss of weight of patients due to the intrinsic anabolic activity of the steroid, and (4) did not exert any influence on tumor growth. Judging from these results, administration of the anabolic steroid would appear to be effective for the improvement of the general condition of cancer patients following surgery or in terminal cases.

    The treatment of uterine cervical carcinoma is largely dependent on the tumor stage. Despite significant inaccuracies in the clinical examination, uterine cervical cancer remains the only gynecological form of cancer still largely staged according to clinical findings. Although imaging is still not included in the staging the recently published revised FIGO (Federation International de Gynecologie et d'Obstetrique) system encourages the use of modern cross-sectional imaging (magnetic resonance imaging MRI and computed tomography CT). Due to its high soft tissue contrast MRI allows excellent non-invasive assessment of the cervix with direct tumor delineation as well as assessment of the prognosis based on morphological factors. Studies in the literature report an accuracy of 93% for MRI in the preoperative assessment of tumor size and in the differentiation of operable from advanced cervical cancer. Therefore MRI is considered to be the optimal modality for diagnostic evaluation starting from FIGO stage IB1, for radiation therapy planning, and for exclusion of recurrence in follow-up. In this paper we give an overview of the role of magnetic resonance imaging in preoperative staging of uterine cervical cancer. (orig.) [German] Die Therapieplanung beim Zervixkarzinom ist weitgehend von der Stadieneinteilung nach FIGO (Federation International de Gynecologie et d'Obstetrique) abhaengig, die trotz erheblicher Ungenauigkeiten bei der klinischen Stadieneinteilung weiterhin aufgrund klinischer Untersuchungsbefunde erfolgt. Obwohl bildgebende Verfahren nach wie vor fuer die Stadieneinteilung nicht vorgesehen sind, wird im kuerzlich erschienen revidierten Stagingsystem der FIGO zum ersten Mal die Verwendung moderner Schnittbilddiagnostik (MRT und CT) befuerwortet. Die MRT ermoeglicht dank ihres hohen Weichteilkontrasts ein ausgezeichnetes nichtinvasives Staging des Zervixkarzinoms mit direkter Tumordarstellung sowie einer Prognoseabschaetzung anhand

    To evaluate the outcomes of adjuvant radiotherapy (RT) and to analyze prognostic factors of survival in the International Federation of Gynecology and Obstetrics (FIGO) IB-IIA uterine cervical cancer. We retrospectively reviewed the medical records of 148 patients with FIGO IB-IIA uterine cervical cancer who underwent surgery followed by adjuvant RT at the Yonsei Cancer Center between June 1997 and December 2011. Adjuvant radiotherapy was delivered to the whole pelvis or an extended field with or without brachytherapy. Among all patients, 57 (38.5%) received adjuvant chemotherapy either concurrently or sequentially. To analyze prognostic factors, we assessed clinicopathologic variables and metabolic parameters measured on preoperative {sup 18}F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). To evaluate the predictive performance of metabolic parameters, receiver operating characteristic curve analysis was used. Overall survival (OS) and disease-free survival (DFS) were analyzed by the Kaplan-Meier method. The median follow-up period was 63.2 months (range, 2.7 to 206.8 months). Locoregional recurrence alone occurred in 6 patients, while distant metastasis was present in 16 patients, including 2 patients with simultaneous regional failure. The 5-year and 10-year OSs were 87.0% and 85.4%, respectively. The 5-year and 10-year DFSs were 83.8% and 82.5%, respectively. In multivariate analysis, pathologic type and tumor size were shown to be significant prognostic factors associated with both DFS and OS. In subset analysis of 40 patients who underwent preoperative PET/CT, total lesion glycolysis was shown to be the most significant prognostic factor among the clinicopathologic variables and metabolic parameters for DFS. Our results demonstrated that adjuvant RT following hysterectomy effectively improves local control. From the subset analysis of preoperative PET/CT, we can consider that metabolic parameters may hold prognostic

    Full Text Available CONTEXT AND OBJECTIVE: Cancer of the uterine cervix is still very common in Brazil. It is important to evaluate factors that influence its prognosis. The aim here was to analyze the prevalence of prognostic anatomoclinical factors among patients with carcinoma of the uterine cervix undergoing radical hysterectomy. DESIGN AND SETTING: Cross-sectional study on 301 patients with invasive carcinoma of the uterine cervix who underwent Level III Piver-Rutledge hysterectomy surgery at São Marcos Hospital. METHODS: The following variables were analyzed: age, histological type, degree of differentiation, invasion of lymphatic, vascular and perineural space, lymph node metastasis, distance to nearest margin, tumor invasion depth, vaginal cuff size, largest diameter of the tumor, presence of necrosis and surgical margin involvement. Descriptive statistics, multiple regression analysis, Kaplan-Meier survival curves and the log-rank test were performed. A significance level of 5% was used. RESULTS: The mean age was 48.27 years. The following were not important for the prognosis, in relation to survival analysis: degree of differentiation and tumor invasion depth; presence of lymphatic, blood and perineural invasions; distance to nearest margin; and vaginal cuff size. Tumor size (P < 0.036, presence of lymph node metastasis (P < 0.0004, necrosis (P < 0.05 and surgical margin involvement (P < 0.0015 presented impacts on survival. The overall survival with 98 months of follow-up was 88.35%. CONCLUSION: The most prevalent prognostic factors were the presence of lymph node metastasis, tumor size and surgical margin involvement.

    A relation between apparent diffusion coefficient (ADC) values and tumor cellular density has been reported. The purpose of this study was to measure the ADC values of cervical cancers in the uterus and compare them with those of normal cervical tissues, and to test whether ADC could differentiate between normal and malignant cervical tissues in the uterus. Twelve consecutive female patients with cervical cancer of the uterus and ten female patients with other pelvic abnormalities were included in this study. ADC was measured at 1.5 T with b-factors of 0, 300 and 600 s/mm{sup 2} using single-shot echo-planar diffusion-weighted imaging and a parallel imaging technique. The mean ADC value of cervical cancer lesions was 1.09{+-}0.20 x 10{sup -3} mm{sup 2}/s, and that of normal cervix tissue was 1.79{+-}0.24 x 10{sup -3} mm{sup 2}/s (P<0.0001). In nine patients treated by chemotherapy and/or radiation therapy, the mean ADC value of the cervical cancer lesion increased significantly after therapy (P<0.001). The present study showed, with a small number of patients, that ADC measurement has a potential ability to differentiate between normal and cancerous tissue in the uterine cervix. Further study is necessary to determine the accuracy of ADC measurement in monitoring the treatment response. (orig.)

    Full Text Available CONTEXT AND OBJECTIVE: Pap smears are the most common and inexpensive screening method for cervical cancer. We analyzed micronucleus prevalence in exfoliated cervical mucosa cells, to investigate associations between increased numbers of micronuclei and risk factors for cervical cancer. DESIGN AND SETTING: Analytical cross-sectional study, at Instituto de Pesquisa em Oncologia (IPON. METHODS: Exfoliated cervical cells were obtained from 101 patients between September 2004 and November 2005. Patients' ages, habits (passive or active smoking, alcoholism and numbers of sexual partners, age at first sexual intercourse, contraceptive methods used, histories of sexually transmitted diseases, use of hormone replacement therapy, numbers of pregnancies and abortions, inflammatory cytology and cervical intraepithelial neoplasia (CIN were obtained. Cells were collected using Ayre spatulas, transferred to vials containing 0.9% saline solution for micronucleus tests and analyzed at 1000x magnification. The number of micronuclei in 1,000 epithelial cells per patient sample was counted. RESULTS: Comparisons between groups with active (7.9 ± 7.8 and passive (7.2 ± 10.6 smoking versus no smoking (3.7 ± 5.1; with/without alcoholism (7.8 ± 1.4 and 6.9 ± 10.1; with/without inflammatory cytology (10.7 ± 10.5 and 1.3 ± 1.7; and with CIN I, II and III and no CIN (respectively 4.3 ± 4.3, 10.6 ± 5.3, 22.7 ± 11.9 and 1.3 ± 1.4 found elevated micronucleus prevalence (P < 0.05. CONCLUSIONS: We concluded that the prevalence of micronuclei in exfoliated uterine cervical cells was greater in patients with one or more risk factors for uterine cervical cancer than in patients without risk factors.

    Today around 275000 women a year in the world keep dying from the cancer of uterine cervix due to the difficulty to meet the logistic requirements of an organized screening in the developing world. Polarimetric imaging is a new promising technique with a tremendous potential for applications in biomedical diagnostics: it is sensitive to slight morphological changes in tissues, can provide wide field images for the screening and requires light sources such as a LED for example. This work intends to characterize the polarimetric response of the uterine cervix in its healthy and pathological states. An extensive series of ex-vivo measurements is in progress the Kremlin Bicêtre hospital near Paris using an imaging multispectral Mueller polarimeter in backscattering configuration. The goal of this study is to evaluate the performances of polarimetric imaging technique in terms of sensitivity and specificity for the detection of healthy epithelia (Healthy Squamous epithelium and Malpighian Metaplasia) with respect to the diagnosis provided by pathologists from histology slides as the "gold standard". We show that, at λ=550nm, performances as high as 62% sensitivity and 64% specificity are achieved by optimizing a simple threshold on the scalar retardance values.

    Full Text Available AIMS: To find out the status of DNA, RNA and protein in human uterine, ovarian, breast and rectal carcinoma. MATERIAL AND METHODS: In this prospective study, patients of age group between late thirties and late fifties suffering from uterine, ovarian, breast and rectal cancer were taken as subjects of the present study. The total number of cases studied for each cases was ten. Pieces of human carcinomatous tissues of above mentioned cases were taken along with surrounding normal tissues. From the tissue samples, putrescine is separated by the method of Herbst et al, DNA analysed by Diphenylamine method, RNA by Orcinol method and protein by Biuret method. RESULTS: Tissue content of putrescine rises simultaneously with that of DNA, RNA and protein in carcinomatous growths as above in comparison to their respective adjacent normal tissue, the differences being statistically highly significant. CONCLUSIONS: Increase in DNA, RNA and protein concentration may be a pre-requisite for increased synthesis of putrescine in carcinomatous tissue and thereby the concentration of other di- and poly-amines.

    Efficacy, survival rates and adverse effects of the combined therapy of irradiation with intravaginal bleomycin suppositories were analyzed and discussed in 49 patients with uterine cervical cancer. The results were as follows: 1. Histological examination of biopsy specimens from the uterine cervix taken just after the completion of this treatment showed favorable control over the primary lesions. However, the efficacy of the bleomycin suppositories was too mild to form a basis for treatment without intracavitary irradiation. Because of the low concentration of bleomycin in serum after suppository administration, it is thought that bleomycin would have little effect on distant metastases. 2. Survival rates in stage III patients were 83% at 12 months, 77% at 24 months and 70% at 36 months. These were superior to those for irradiation alone. 3. The major adverse effect of bleomycin suppositories was fever, reduction of the bleomycin dose in each suppository but controlled this to some extent Lung fibrosis or severe damage to the liver, kidney and bone marrow were not found.

    Cancer procoagulant (CP) is a sulfhydryl proteinase thought to be synthesized mainly by neoplastic cells. Consequently, increased CP activity in blood serum was interpreted as being associated with the presence of a proliferative process in the host's body. To date, CP activity has not been systematically studied in cases of genital carcinoma. The present study is aimed at evaluation of CP activity in women with genital carcinoma. A case-controlled study backed up by histopathological examination. Peripheral blood was sampled preoperatively in a sterile manner from an antecubital vein, from 16 women with cervical carcinoma and 15 women with uterine carcinoma. Blood for the reference group of 12 healthy women was obtained in an identical manner after an overnight fast. The CP activity in serum was determined using the coagulative method according to Gordon and Benson, and was expressed as coagulation time in seconds (s). The CP activity in 10% tissue homogenates (in saline) of genital cancer was determined by the chromogenic method according to Colucci et al. The mean CP activity in serum of women with cervical carcinoma (78.28 +/- 15.25 s) and of women with uterine carcinoma (79.63 +/- 12.02 s) was significantly different (P < 0.0001) from the respective values found in healthy women (281.33 +/- 43.19 s). The CP activity in neoplastic tissue was 28.50 +/- 6.40 nmol pNa/mL for cervical carcinoma, and 28.31 +/- 3.92 nmol pNa/mL for uterine carcinoma, both values being significantly higher (P < 0.0009) than the activity found in the normal tissues. There was no established relationship between neoplastic CP activity and FIGO staging of the disease. This is the first study to demonstrate the concomitant presence of CP activity in serum and neoplastic tissue of women with genital carcinoma. These patients have decreased coagulation time and thus are likely to develop coagulation disturbances in the course of their cancer. There may be a role for CP as a tumor marker of

    The pyometra is a rare condition, with an incidence of less than 1%. In patients with cervical cancer, spontaneous rupture of pyometra manifests as a generalized peritonitis, which is extremely rare, in the literature only seven cases are described. This paper reports the case of a patient with a history of postmenopausal vaginal bleeding one month before her admission to the hospital; she attended because of acute abdomen. The CT scan reported air in the abdominal cavity and the uterus with air at the periphery, so she underwent an exploratory laparotomy in which purulent material was found with two perforations in the uterine fundus. She underwent total abdominal extrafacial hysterectomy with histopathological diagnosis of keratinizing squamous cell carcinoma, moderately differentiated.

    Background. Cervical carcinoma is the only gynecological tumor still being staged mainly by clinical examination and only a limited use of diagnostic radiology. Cross sectional imaging is increasingly used as an aid in the staging procedure. We wanted to assess the impact of magnetic resonance imaging (MRI) in addition to the clinical staging of patients with carcinoma of the uterine cervix. Material and methods. A retrospective single-centre analysis of 183 women referred to a tertiary referral centre for gynecological tumors (<= 65 years old) with cervical cancer diagnosed between January 1, 2003 and December 31, 2006 who have undergone an MRI investigation before start of treatment. Patient records were retrospectively reviewed and any change of the planned treatment after the MRI examination was noted. Results. In patients with cervical carcinoma FIGO stage Ia2-IIa treated surgically, the treatment plan was altered due to MRI results in 10/125 patients. In the smaller group of patients with clinically more advanced disease receiving radio-chemotherapy, the treatment plan was altered in 12/58 patients. Reasons for changing the treatment plan after MRI were findings indicating a higher (n = 8) or lower (n = 5) local tumor stage, findings of para aortic nodal disease (n = 4) or difficulty to clinically examine the patient due to obesity (n = 2). MRI was also an aid in deciding whether or not to offer fertility preserving treatment in three cases. Conclusion. The use of MRI affects treatment planning in patients with cancer of the uterine cervix. The impact is more obvious in more advanced stages of disease and in patients who are difficult to examine clinically due to, for example body constitution. The result of MRI is also an aid in deciding whether or not a fertility preserving operation is feasible

    Cervical cancer complicated by complete uterine prolapse is a rare clinical entity and uniform management recommendations have yet to be determined. The aim of the current review was to examine the effects of management patterns on survival outcomes in cervical cancer patients with complete uterine prolapse. A systematic review of the literature was conducted using three public search engines. This included case reports with detailed descriptions of tumor characteristics, cancer management, and survival outcomes. Treatment patterns and tumor characteristics were correlated to survival outcomes. There were 78 patients with cervical cancer with complete uterine prolapse. Their mean age was 63.7 years. The median duration of prolapse was 147.9 months and 22.2% of the patients experienced persistent/recurrent prolapse after cancer treatment. The mean tumor size was 8.9 cm and squamous cell carcinoma (83.9%) was the most common histologic type. The majority of patients (56.2%) had stage I cancer. Tumor characteristics were similar across the treatment patterns. Survival outcomes were more favorable with surgery-based treatment (48 patients) than with radiation-based treatment (30 patients): 5-year recurrence-free survival rate 72.0% vs. 62.9% (p = 0.057), and 5-year disease-specific overall survival rate 77.0% vs. 68.2% (p = 0.017). After controlling for age and stage, surgery-based therapy remained an independent prognostic factor for better disease-specific overall survival outcome (hazard ratio 0.32, 95% confidence interval 0.11 - 0.94, adjusted p = 0.039). Although limited in study size, our results at least suggest that surgery-based treatment may have a positive effect on survival outcome in cervical cancer patients with complete uterine prolapse.

    The association between H. pylori infection and pancreatic cancer risk remains controversial. We conducted a nested case-control study with 448 pancreatic cancer cases and their individually matched control subjects, based on the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort, to determine whether there was an altered pancreatic cancer risk associated with H. pylori infection and chronic corpus atrophic gastritis. Conditional logistic regression models were applied to calculate odds ratios (ORs) and corresponding 95% confidence intervals (CIs), adjusted for matching factors and other potential confounders. Our results showed that pancreatic cancer risk was neither associated with H. pylori seropositivity (OR = 0.96; 95% CI: 0.70, 1.31) nor CagA seropositivity (OR = 1.07; 95% CI: 0.77, 1.48). We also did not find any excess risk among individuals seropositive for H. pylori but seronegative for CagA, compared with the group seronegative for both antibodies (OR = 0.94; 95% CI: 0.63, 1.38). However, we found that chronic corpus atrophic gastritis was non-significantly associated with an increased pancreatic cancer risk (OR = 1.35; 95% CI: 0.77, 2.37), and although based on small numbers, the excess risk was particularly marked among individuals seronegative for both H. pylori and CagA (OR = 5.66; 95% CI: 1.59, 20.19, p value for interaction < 0.01). Our findings provided evidence supporting the null association between H. pylori infection and pancreatic cancer risk in western European populations. However, the suggested association between chronic corpus atrophic gastritis and pancreatic cancer risk warrants independent verification in future studies, and, if confirmed, further studies on the underlying mechanisms.

    though hyperthermia is a promising improvement of cancer treatment, multiple obstacles remain to be cleared. One of the major issues is that the tumor temperatures that must be reached for obtaining clinical efficacy are undefined (Wust et al., 2002). In the present study, we monitored the temperature transition in tumors during HIPEC in ovarian cancer patients (Figure S1). Even though the perfusion temperature at the entrance was maintained at 42.5°C, the temperature in most of the tumors was about 40°C, which is the temperature seen with just a high fever, and the clinical benefit of these lower temperatures was unclear. Also, no data on predictors of sensitivity of ovarian and uterine tumors to hyperthermia has been addressed. The purpose of the present study was to determine the molecular mechanism of response of gynecological cancer cells to hyperthermia. We hypothesized that inhibition of a critical gene of hyperthermia resistance by small interfering RNA (siRNA) can sensitize ovarian and uterine cancers to hyperthermia. To achieve this, we explored the genes that regulate hyperthermia resistance by comparing gene and protein expression between hyperthermia sensitive and resistant cells. We performed that silencing of the novel target gene could sensitize hyperthermia resistant cancer cells to hyperthermic treatment both in vitro and orthotopic ovarian cancer models in vivo with copper sulfate nanoparticles and near-infrared laser treatment.

    The purpose is to evaluate the accuracy of integrated FDG-PET/CT, compared with PET alone, for diagnosis of suspected recurrence of uterine cervical cancer. Fifty-two women who had undergone treatment for histopathologically proven cervical cancer received PET/CT with suspected recurrence. PET-alone and integrated PET/CT images were evaluated by two different experienced radiologists by consensus for each investigation. A final diagnosis was confirmed by histopathology, radiological imaging, and clinical follow-up for over 1 year. Patient-based analysis showed that the sensitivity, specificity, and accuracy of PET/CT were 92.0% (23/25), 92.6% (25/27), and 92.3% (48/52), respectively, while for PET, the corresponding figures were 80.0% (20/25), 77.8% (21/27), and 78.8% (41/52), respectively. PET/CT resolved the false-positive PET results due to hypermetabolic activity of benign/inflammatory lesions and physiological variants, and was able to detect lung metastasis, local recurrence, peritoneal dissemination, para-aortic lymph node metastasis, and pelvic lymph node metastasis missed by PET alone. However, tiny local recurrence and lymph node metastasis could not be detected even by PET/CT. FDG-PET/CT is a useful complementary modality for providing good anatomic and functional localization of sites of recurrence during follow-up of patients with cervical cancer. (orig.)

    A case of rectovesicovaginal fistula caused by pelvic radiation for uterine cancer is presented. A 62-year-old woman visited our department complaining of macroscopic hematuria, mictional pain and pollakisuria. She had a history of total hysterectomy and radiation therapy for cervical cancer 26 years earlier. Melena was noted in March 1994 and an escape of stool from the vagina followed nine months later. She consulted a surgeon about it, however no active treatment was performed before coming under our care. Computed tomography demonstrated that the posterior bladder wall was extremely thin and the possibility of the formation of vesical perforation was strongly suggested. We constructed transverse-colostomy, however, a rectovesicovaginal fistula developed seven months later. Therefore, in order to regain a dry life, an ileal conduit was constructed and her quality of life began to improve. It is probable that the rectovesicovaginal fistula could have been prevented if colostomy had been carried out soon after the appearance of melena or soon after the formation of the rectovaginal fistula.

    The expression of plasminogen activator inhibitor type 1 (PAI-1), vascular endothelial growth factor (VEGF), and transforming growth factor β1 (TGF-β1) participates in the angiogenesis of several cancer types. The goal of this study was to investigate polymorphisms in genes related to angiogenesis (PAI-1-675 4G/5G, VEGF C936T, and TGF-β1 G-800A) to evaluate the risk for developing uterine cervical cancer (UCC). In a case-control study, 100 healthy subjects and 100 patients with UCC from Mexico were included. We determined the genetic profile of the polymorphic markers, which were evaluated by polymerase chain reaction using a sequence-specific primer. There was no statistical difference in the allele distribution from the intergroup comparisons of PAI-1 675 4G/5G and VEGF C936T data; however, a significant difference was observed within TGF-β1 G-800A. The linkage disequilibrium analysis revealed that PAI-1 -675 4G and TGF-β1 -800A pair-haplotype was in strong linkage disequilibrium with a significantly increased risk (odds ratio, 3.44; 95% confidence interval, 1.66-7.25) to UCC. The polymorphisms in the genes related to angiogenesis -675 4G/5G PAI-1 and G-800A TGF-β1, segregated solely or combined, might contribute to the increased susceptibility to UCC in a Mexican population.

    The aim of this study was to develop an appropriate definition for vaginal cuff and paracolpium clinical target volume (CTV) for postoperative intensity modulated radiation therapy in patients with uterine cervical cancer. A working subgroup was organized within the Radiation Therapy Study Group of the Japan Clinical Oncology Group to develop a definition for the postoperative vaginal cuff and paracolpium CTV in December 2013. The group consisted of 5 radiation oncologists who specialized in gynecologic oncology and a gynecologic oncologist. A comprehensive literature review that included anatomy, surgery, and imaging fields was performed and was followed by multiple discreet face-to-face discussions and e-mail messages before a final consensus was reached. Definitions for the landmark structures in all directions that demarcate the vaginal cuff and paracolpium CTV were decided by consensus agreement of the working group. A table was created that showed boundary structures of the vaginal cuff and paracolpium CTV in each direction. A definition of the postoperative cervical cancer vaginal cuff and paracolpium CTV was developed. It is expected that this definition guideline will serve as a template for future radiation therapy clinical trial protocols, especially protocols involving intensity modulated radiation therapy.

  20. Cytopathologic evaluation of patients submitted to radiotherapy for uterine cervix cancer

    Directory of Open Access Journals (Sweden)

    Cátia Martins Leite Padilha

    Full Text Available Summary Cervical cancer is an important public health problem. Pap smear is the leading strategy of screening programs for cervical cancer worldwide. However, delayed diagnosis leads to more aggressive and less effective treatments. Patients with uterine cervix malignancies who are referred for radiotherapy have advanced-stage disease, which results in high rates of locoregional recurrence. The use of radiotherapy as a treatment for cervical cancer causes morphological changes in neoplastic and non-neoplastic epithelial cells, as well as in stromal cells, which make it difficult to diagnose the residual lesion, resulting in a dilemma in cytopathological routine. Based on the difficulties of cytopathologic evaluation for the follow-up of patients treated with radiotherapy for cervical cancer, our objective was to describe the actinic cytopathic effects. Our paper was based on a structured review including the period from June 2015 to April 2016, aiming at an exploratory-descriptive study. Bibliographic investigations were carried out through selection and analysis of articles, list of authors and keywords, selection of new articles focused on the analysis of bibliographic references to previously selected documents, as well as textbooks of recognized merit. The most incident actinic cytopathological alterations as described in the literature are: cellular gigantism, nuclear and cytoplasmic vacuolization, dyskeratosis, bi- and multinucleated (B/M cells, macro and multiple nucleoli, anisokaryosis, anisonucleolosis and nuclear pyknosis. To date, a protocol has not been established that can precisely differentiate the morphological characteristics between benign cells with actinic effects from recurrent malignant cells on post-radiotherapy smears.

    Full Text Available Objective. This study assesses the role of preoperative serum CA125 levels in the planning treatment options for women diagnosed with uterine cancer. Material and Method. Ninety five consecutive patients diagnosed with uterine cancer during a four-year period were identified. Age ranged from 35 to 89 years with a mean age of 69 years. The preoperative CA125 levels were dichotomised at 28 U/mL (using ROC analysis to identify the best discriminating threshold for 5-year survival. This level was then correlated with preoperative prognostic indicators: patient age, tumour grade, and histopathological tumour cell type. Survival data was plotted using Kaplan-Meier curves and analysed using the log-rank test. Univariate and multivariate analysis were performed to identify the predictors of overall survival. Results. The mean age of patients was 69 years (range: 35–89. On univariate analysis, the use of preoperative CA125 levels of greater or less than 28 U/mL correlated significantly with age (P=0.01, the grade of disease (P=0.02 and unfavourable tissue type (P=0.03. This threshold CA125 level had a sensitivity of 75%, specificity of 76%, positive predictive value of 35% and negative predicative value of 96.25%, and a likelihood ratio of 3.12 for predicting nodal disease. Using a threshold of preoperative CA125 level of 28 U/mL (area under curve: 0.60 was also a significant predictor of 5-year survival (log-rank test, P=0.01. Using Cox multivariate survival analysis to identify predictive preoperative factors overall, unfavourable cell type was the strongest predictor of survival (Chi square = 36.5, df = 4, and P=0.001, followed by preoperative CA125 level (CA125 > 28 U/mL, P=0.011 and unfavourable preoperative grade (P=0.017. Amongst patients with a favourable histological tissue type (endometrioid, preoperative CA125 levels predicted overall survival (Chi square = 6.039, df = 2, P=0.02; however unfavourable preoperative

    Aim: To investigate the ability of diffusion-weighted imaging (DWI) to predict and monitor the response of uterine cervical cancer to combined chemoradiation using apparent diffusion coefficients (ADCs). Materials and methods: Seventeen women (mean age 48.5 years) with uterine cervical cancer received conventional magnetic resonance imaging (MRI) and DWI prior to chemoradiation and after 1 and 2 months of therapy. A subgroup of eight also had MRI and DWI repeated after 15 days of therapy. Treatment response was determined according to changes in tumour size after 2 months of therapy and was classified as complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD). Pretreatment ADCs were compared between the different disease response groups, and dynamic changes of ADCs in each group were observed. Pearson's correlation test was calculated between those ADC parameters and tumour response. Results: Pretreatment ADCs for CR were significantly lower than those of PR (p = 0.005). Negative correlation was found between pretreatment ADCs and percentage size reduction after 2 months of chemoradiation (p = 0.016). The percentage ADC change after 1 month correlated positively with percentage size reduction after 2 months of therapy (p = 0.021). ADCs after 15 days of therapy increased significantly compared with pretreatment ones (p = 0.001); however, the longest tumour diameter showed no statistically significant change (p = 0.078). Conclusion: ADCs may have the potential to be used to predict and monitor the response of uterine cervical cancer to therapy.

    To explore the effect of dominant negative HIF-1alpha (dn HIF-1alpha) on biological characteristics of uterine cervix cancer cell SiHa and elucidate the related mechanism. pcDNA3. 1-dn HIF-1alpha was transfected into SiHa cells. The expression of HIF-1alpha and VEGF protein were detected by immunocytochemical method and Western Blotting. The growth proliferation of cells was surveyed by the MTT assay and cell apoptosis was detected through TUNEL after treated with CoCl2, meanwhile the results were compared with the group transfected with mock plasmid and untransfected group. After successfully transfected with relevant plasmid, there's no obvious difference of expression of HIF-1alpha among dn HIF-1alpha group, pcDNA3. 1 group, and untransfected group, however the expression of VEGF of dn HIF-1alpha group was significantly lower than that of the others (P dn HIF-1alpha group was obviously lower than that of the other two (P dn HIF-1alpha group among these three (P < 0.05). Domain negative HIF-1alpha can inhibit the proliferation of uterine cervix cancer cell and accelerate its apoptosis under hypoxia induced by CoCl2, as well as decrease the expression of VEGF protein. The implications of all this were that the domain negative HIF-1alpha may play an important role in the therapy of uterine cervix cancer.

    The aim of this study was to retrospectively compare in a series of 110 patients with early-stage endometrial cancer recurrence rate and surgical outcomes after total laparoscopic (LPS) hysterectomy with lymphadenectomy performed with or without uterine manipulator. 110 patients with clinical stage I endometrial cancer were enrolled in a retrospective study and underwent surgical staging comprised of LPS hysterectomy, bilateral salpingo-oophorectomy, and in all cases we performed systematic bilateral pelvic lymphadenectomy with uterine manipulator (Group 1, 55 patients) or without (Group 2, 55 patients). The rate of positive cytology and LVSI did not significantly differ between Group 1 and Group 2. 1 patient of the Group 1 had a bladder injury and another patient of Group 2 had an ureteral stricture temporarily treated with a stent. 1 patient of the Group 1 had a bowel occlusion due to a port site hernia under the left 10 mm port, resolved with a bowel resection and an end-to-end anastomosis. In 1 patient of the Group 1 and 2 patients of Group 2 we observed a vaginal cuff dehiscence and in 1 case of Group 2 a pelvic lymphocyst was reported. Postoperative fever was reported in 3 patients of the Group 1 and in 5 patients of group 2 (p = 0.07). Our study confirms that use of uterine manipulator for laparoscopic treatment of endometrial cancer does not increase positive peritoneal citology, LVSI and recurrence rate.

    Background: The 2009 International Federation of Gynecologists and Obstetricians elected to substage patients with positive retroperitoneal lymph nodes as IIIC 1 (pelvic lymph node metastasis only) and IIIC 2 (paraaortic node metastasis with or with positive pelvic lymph nodes). We have investigated the discriminatory ability of subgrouping patients with retroperitoneal nodal involvement based on location, number, and ratio of positive nodes. Methods: For 1075 patients with stage IIIC endometrioid corpus cancer abstracted from the Surveillance, Epidemiology, and End Results databases for 2003–2007, Kaplan–Meier analyses, Cox proportional hazard models, and other quantitative measures were used to compare the prognostic discrimination for disease-specific survival (DSS) of nodal subgroupings. Results: In univariate analysis, the 3-year DSS were significantly different for subgroupings by location (IIIC 1 vs IIIC 2; 80.5% vs 67.0%, respectively, P=0.001), lymph node ratio (⩽23.2% vs >23.2% 80.8% vs 67.6% P5; 79.5, 75.4, 62.9%, P=0.016). The ratio of positive nodes showed superior discriminatory substaging in Cox models. Conclusion: Subgrouping of stage IIIC patients by the ratio of positive nodes, either as a dichotomized or continuous parameter, shows the strongest ability to discriminate the survival, controlling for other confounding factors.

    From May 1991 through September 1992, a total of 17 previously untreated patients with invasive uterine cervix cancer and with intact uterus were treated with mid-dose rate intracavitary therapy administered with a Selectron. Early primary tumor responses for all patients were complete. No acute or subacute radiation injury was observed except one patient with aplastic anemia who developed rectal ulcer. Two patients of Stage IIIb died from tumor because of local, paraaortic lymph node and distant metastases. Our early experience concluded that Selectron MDR can be used for cervix cancer patients as safely and effectively as our previously used high-dose rate machine. (author).

    Troglitazone (TRO), a PPAR-{gamma} agonist, can reduce heat shock protein (HSP) 70 and increase the antioxidant enzymes, such as superoxide dismutase (SOD) and catalase, which might affect thermal sensitivity. Here, we investigated whether TRO modifies thermal sensitivity in uterine cervical cancer cells, which is most commonly treated by hyperthermia (HT). HeLa cells were treated with 5{mu}M TRO for 24 hours before HT at 42 .deg. C for 1 hour. Cell survival was analyzed by clonogenic assay. The expression of HSPs was analyzed by Western blot. SOD and catalase activity was measured and reactive oxygen species (ROS) was measured using 2',7'-dichlorofluorescin diacetate and dihydroethidium. The decreased cell survival by HT was increased by preincubation with TRO before HT. Expression of HSP 70 was increased by HT however, it was not decreased by preincubation with TRO before HT. The decreased Bcl-2 expression by HT was increased by preincubation with TRO. SOD and catalase activity was increased by 1.2 and 1.3 times, respectively with TRO. Increased ROS by HT was decreased by preincubation with TRO. TRO decreases thermal sensitivity through increased SOD and catalase activity, as well as scavenging ROS in HeLa cells.

    A trial comparing two different radiotherapy techniques and schedules is the treatment of 83 patients with advanced cancer of the uterine cervix (stage IIIB) employing external irradiation alone is described. The one technique, used routinely in this department, employed a conventional daily fractionation schedule while the other used a high-dose weekly fractionation regimen. The techniques are described. The aim of the trial was to compare the efficacy and morbidity of these two methods of treatment. Dose distribution curves in cross-section and midsagittal planes are shown and calculations or equivalent doses at various selected points using Ellis's nominal single-dose formula are tabulated. The 2-year survival figures were 33% for the daily fractionation technique and 22% for the weekly regimen. Serious late complication rates were 6% for the daily regimen and 22% for the weekly schedule. These differences are not statistically significant. Late complication rates in the weekly fractionation regimen appeared to be lower than figures quoted by other authors. Local control within the irradiated volume was better in the group treated by the daily fractionation method.

    To report clinical outcomes following adjuvant high-dose-rate (HDR) vaginal brachytherapy (VB) for early-stage uterine papillary serous (UPSC) and clear cell (CC) endometrial cancer. A retrospective study of Stage I and II papillary serous and clear cell endometrial cancer treated with post-operative HDR VB between October 2005 and May 2012 was performed. A total of 37 patients were identified, 26 with UPSC, 9 with CC and 2 with mixed UPSC/CC. After total hysterectomy and bilateral salpingo-oophorectomy, VB was administered without external-beam radiation with a dose of 24 Gy in 6 fractions prescribed to the vaginal surface. Chemotherapy was given to 30 patients (75%). The median follow up time was 24.8 months (range, 2.0 to 71.5 months). Four patients relapsed, 2 with UPSC and 2 with CC. The initial site of relapse was concurrent vagina, pelvic/para-aortic nodes and abdominal wall (1), pelvic/para-aortic nodes (1) and para-aortic nodes alone (2). The 2-year vaginal-control rate was 96.8%. The pelvic-control rate including vaginal and nodal relapse was 93.5%. The 2-year disease-free and overall survival rates were 89.3% and 100%, respectively. HDR VB as the sole adjuvant treatment modality for early-stage UPSC/CC is associated with a low rate of vaginal relapse and excellent survival outcomes. This novel low-dose regimen for VB is safe and effective. Copyright © 2012 Elsevier Inc. All rights reserved.

    Purpose: To prospectively investigate the changes in bone mineral density (BMD) after pelvic radiation therapy in patients with uterine cervical cancer. Methods and Materials: Of 52 cervical cancer patients who received pelvic RT in our university hospital between 2009 and 2011, 46 patients without recurrence and who were followed up for more than 12 months were included in the study. The BMD of the irradiated region and nonirradiated regions, serum estradiol, tartrate-resistant acid phosphatase-5b, and N-terminal cross-linking telopeptide of collagen 1 were measured before, at 3 months after, and at 12 months after RT. The patient cohort was divided into 2 groups according to estradiol level before RT, and the groups were defined as postmenopausal (<40 pg/mL) and premenopausal (≥40 pg/mL). Results: The mean BMDs within the irradiation field (lumbar vertebra 5) in the postmenopausal and the premenopausal groups were 0.825 and 0.910 g/cm{sup 2} before RT and 0.746 and 0.841 g/cm{sup 2} 12 months after RT, respectively. Significant decreases were observed in both groups (P<.05 and P<.01, respectively). In addition, in the premenopausal group the mean BMDs of the nonirradiated regions at thoracic vertebrae 9-12 and lumbar vertebrae 2-4 were 0.753 and 0.958 g/cm{sup 2} before RT and were significantly decreased to 0.706 and 0.921 g/cm{sup 2} 12 months after RT (P<.01 and P<.05, respectively). Estradiol significantly decreased 3 months after RT, whereas tartrate-resistant acid phosphatase-5b and N-terminal cross-linking telopeptide of collagen 1 continued to increase over time in the premenopausal group. Conclusions: A decrease in BMD in the irradiated region after RT was observed within 1 year, regardless of menopausal status. Furthermore, in premenopausal patients, pelvic RT caused a decrease in systemic BMD.

    Uterine leiomyomas and endometrial pathology are both associated with abnormal uterine bleeding. We report a case in which a nulliparous woman with heavy uterine bleeding and leiomyomas had undergone two prior hysteroscopic myomectomies for benign leiomyomas. She was evaluated, but was ineligible for a clinical trial of a novel Magnetic Resonance guided High Intensity Focused Ultrasound (MRgx200B;HIFU) device. The 8 cm, prolapsed submucosal leiomyoma hindered endometrial sampling and was inaccessible to HIFU treatment. Preoperatively, neither endometrial sampling nor saline sonohysterography was technically feasible. She underwent hysterectomy, and on histological examination of specimen, stage 1A grade 1 endometrial carcinoma was found on the endometrial side of the prolapsing fibroid. Endometrial pathology is an important consideration in the evaluation of abnormal uterine bleeding, even in women with large prolapsing leiomyoma.

    There is a serious, and growing, concern about the increased risk of the emergence of a second cancer, induced by radiation associated with the radiation treatment. To assess the radiation doses to organs outside the target volume, in this work, we modeled several computational exposure scenarios, based on Monte Carlo simulation (MCNPX code). We used a VARIAN 2100c accelerator, and a female virtual anthropomorphic phantom to simulate a treatment of uterine cancer. The results presented show that the computational exposure scenario provides a versatile and accurate tool to assess the risk of secondary cancer. (author)

    The objective was to determinate the diagnostic value of manual vacuum aspiration with Karman cannula (MVA) for the detection of endometrial hyperplasia and cancer in patients with abnormal uterine bleeding. Fifty patients with abnormal uterine bleeding were evaluated with MVA prior to dilatation and curettage (D&C). The needing of cervical dilatation was noted. A matched analysis of the histological reports with Wilcoxon contrast test was performed. In order to calculate the diagnostic value, the histological examination of the tissue recollected by D&C was defined as gold-standard. Sensitivity, specificity, pre-test probability (prevalence), post-test probabilities (predictive values) and likelihood-ratios were calculated. No significant difference between either histological reports in matched analysis and the insufficient samples proportion was detected. Cervical dilatation was performed more frequently to D&C (p = 0.0002). The pre-test probability (prevalence) of endometrial hyperplasia/cancer was 20%. Two cases of hyperplasia were not detected by MVA (negative false 20%). The endometrial biopsy for MVA showed a sensitivity of 71% and specificity 93%. The post-test probabilities for an abnormal and normal biopsy (positive and negative predictive values) were 62.5% and 95.2%, respectively. The corresponding likelihood-ratios were 10.23 and 0.3, respectively. The endometrial biopsy for MVA has a high diagnostic value, similar to D&C, in the detection of endometrial hyperplasia/cancer in patients with abnormal uterine bleeding with the advantage to be an office procedure without either risks and costs of D&C.

    Objective: To evaluate the efficacy of post-treatment positron emission tomography (PET)/computed tomography (CT) for identification of tumor recurrence, and to determine whether [{sup 18}F]fluorodeoxyglucose (FDG) uptake measured as the maximum standardized uptake value (SUV{sub max}) has predictive role regarding survival in patients with uterine cervical cancer. Methods: Medical records from 276 women with uterine cervical cancer who had post-treatment [{sup 18}F]FDG PET/CT performed were retrospectively reviewed. Results of PET/CT scans were compared with histological or clinical examination. Results: Ninety-five (34.4%) of the 276 patients had documented recurrence by either surgical biopsy or clinical and imaging follow-up. Median duration from treatment to PET/CT scan was 24 months (range, 6-307). The overall sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of post-treatment PET/CT were 94.7%, 87.8%, 80.4%, 97%, and 90.2%, respectively. The PET/CT scan modified both the diagnostic or treatment plan in 67 patients (24.3%). Patients were divided into two groups according to cut-off SUV{sub max} established on the basis of ROC analysis (<5.25 vs. {>=}5.25), and there was a significant difference in OS between groups (p = 0.001). In addition, the 5-year progression-free survival (PFS) and OS rates of patients with a negative PET/CT scan for recurrence were significantly better than those with a positive PET/CT (98.62% vs. 17.83%, p < 0.0001 for PFS, 99.31% vs. 85.38%, p = 0.0015 for OS). Conclusion: Post-treatment PET/CT scan is a sensitive and accurate surveillance modality, and provides prognostic information in uterine cervical cancer. Furthermore, it may allow individualization of patient care.

    Full Text Available Serum fucose levels and fucosyl transferase activities have been designated as nonspecific markers of malignancy, and play an important role in the diagnosis of different types of malignancies. In the present study, attempts were made to determine the prognostic significance of these markers in patients with cancer of the uterine cervix after therapy. It was found that both serum fucose and fucosyl transferase, which were elevated in untreated patients declined significantly in patients responsive to therapy at different follow-up intervals, but not in patients unresponsive to therapy.

    An effect of a packing to uterine treatment of a cervical cancer using a dose-volume histogram for a point dose and a volume dose of the bladder and the rectum was analyzed by establishing a three-dimensional treatment plan using a CT image. Reference points of the bladder and the rectum were marked, respectively at a treatment plan device (plato brachytherapy V14.2.4) by photographing CT(marconi, USA) when the packing was used and removed under the same condition and a treatment plan was performed to A point depending on ICRU38. However, in case of the rectum, a maximum point was looked up and compared with the above point because the point presented from the ICRU is not proper as a representative value of a rectum point dose. Further, the volume dose depending on volume of 50%, 80% and 100% point doses of the rectum and the bladder was measured. The measured values were used to analyze the effect of the packing through a Wilcoxon Signed Rank Test (a SAS statistical analysis process program). The reference points at the bladder and rectum doses when the packing was removed were 116.94 35.42% and 117.59 21.08%, respectively. The points when the packing was used were 107.08 38.12% and 95.19 21.32%, respectively. After the packing was used, the reference points at the bladder and the rectum were decreased by 9.86% and 22.4%, respectively. When the packing was removed, the maximum points at the bladder and the rectum were 164.51 50.89%, 128.81 33.05% respectively. When the packing was used, the maximum points at the bladder and the rectum were 142.31 44.79,110.08 37.03%, respectively. After the packing was used, the maximum points at the bladder and the rectum were decreased by 22.2% and 18.73%, respectively. When the packing was removed, the bladder volume at 50%, 80%, and 100% point doses of the rectum and the bladder were 48.62{+-}18.09%, 16.12{+-}11.15%, and 7.51{+-}6.63%, respectively and its rectum volume were 23.41{+-}14.44%, 6.27{+-}4.28%, 2

    Uterine cervix cancer is one of the most prevalent women cancer in Korea. We analysed published papers in Korea with comparing Patterns of Care Study (PCS) articles of United States and Japan for the purpose of developing and processing Korean PCS. We searched PCS related foreign-produced papers in the PCS homepage (212 articles and abstracts) and from the Pub Med to find Structure and Process of the PCS. To compare their study with Korean papers, we used the internet site 'Korean Pub Med' to search 99 articles regarding uterine cervix cancer and radiation therapy. We analysed Korean paper by comparing them with selected PCS papers regarding Structure, Process and Outcome and compared their items between the period of before 1980's and 1990's. Evaluable papers were 28 from United States, 10 from the Japan and 73 from the Korea which treated cervix PCS items. PCS papers for United States and Japan commonly stratified into 3 {approx} 4 categories on the bases of the scales characteristics of the facilities, numbers of the patients, doctors. Researchers restricted eligible patients strictly. For the process of the study, they analysed factors regarding pretreatment staging in chronological order, treatment related factors, factors in addition to FIGO staging and treatment machine. Papers in United States dealt with racial characteristics, socioeconomic characteristics of the patients, tumor size (6), and bilaterality of parametrial or pelvic side wall invasion (5), whereas papers from Japan treated of the tumor markers. The common trend in the process of staging work-up was decreased use of lymphangiogram, barium enema and increased use of CT and MRI over the times. The recent subject from the Korean papers dealt with concurrent chemoradiotherapy (9 papers), treatment duration (4), tumor markers (8) and unconventional fractionation. By comparing papers among 3 nations, we collected items for Korean uterine cervix cancer PCS. By consensus meeting

    We investigated daily needle applicator displacement during multifractionated high-dose-rate interstitial brachytherapy (HDR-ISBT) for postoperative recurrent uterine cancer. Eight patients with postoperative recurrent uterine cancer received HDR-ISBT with or without external beam radiotherapy using our unique ambulatory technique. To analyze displacement, we obtained daily computed tomography (CT) images for 122 flexible needle applicators at 21, 45, 69, and 93 hours after implantation. Displacement was defined as the length between the center of gravity of titanium markers and the needle applicator tips along the daily CT axis. For cases in which displacement was not corrected, we also calculated the dose that covered 90% of the clinical target volume (D90(CTV)) using a dose-volume histogram (DVH). Median caudal needle applicator displacement at 21, 45, 69, and 93 hours was 3, 2, 4, and 5 mm, respectively. More than 15 mm displacement was observed for 2% (2 of 122) and 17% (10 of 60) of needle applicators at 21 and 93 hours, respectively. Cases in which dwell positions were not changed to correct the treatment plan, 2 of 8 patients showed more than 10% reduction in D90(CTV) values compared with the initial treatment plan. Correction of dwell positions of the treatment source improves treatment DVH for multifractionated HDR-ISBT.

    Full Text Available BACKGROUND: This study aimed to investigate the relationships of chitinase 3-like 1 (CHI3L1 single nucleotide polymorphisms (SNPs and haplotypes with the development of uterine cervical cancer in Taiwanese women. The SNPs frequencies and haplotypes were also correlated with the clinicopathologic variables of cervical cancer, cancer recurrence, and patient survival. METHODOLOGY AND PRINCIPAL FINDINGS: Ninety-nine patients with invasive cancer and 61 with pre-cancerous lesions of the uterine cervix were compared to 310 healthy control subjects. Three SNPs rs6691378 (-1371, G/A, rs10399805 (-247, G/A and rs4950928 (-131, C/G in the promoter region, and one SNP rs880633 (+2950, T/C in exon 5 were analyzed by real time polymerase chain reaction and genotyping. The results showed that the mutant homozygous genotype AA of CHI3L1 SNP rs6691378 and AA of rs10399805, and haplotypes AACC and AACT increased the risk of developing pre-cancerous lesions and invasive cancer. The patients with these risk haplotypes had higher than stage I tumors, larger tumors, and vaginal invasion. In logistic regression model, they also tended to have poor survival event [p = 0.078; odds ratio (OR: 2.99, 95% confidence interval (CI: 0.89-10.08] and a higher probability of recurrence event (p = 0.081; OR: 3.07, 95% CI: 0.87-10.81. There was a significant association between the CHI3L1 risk haplotypes and probability of recurrence (p = 0.002; hazard ratio: 6.21, 95% CI: 1.90-20.41, and a marginal association between the risk haplotypes and overall survival (p = 0.051; hazard ratio: 3.76, 95% CI: 0.99-14.29 in the patients with SCC, using Cox proportional hazard model. CONCLUSION: The CHI3L1 SNPs rs6691378 and rs10399805 and CHI3L1 haplotypes all correlated with the development of cervical pre-cancerous lesions and invasive cancer. The cervical cancer patients with the CHI3L1 haplotypes AACC or AACT had poor clinicopathologic characteristics and poor recurrence and survival

    To analyze prognostic factors for locoregional recurrence (LRR), distant metastasis (DM), and overall survival (OS) in cervical cancer patients who underwent radical hysterectomy followed by postoperative radiotherapy (PORT) in a single institute. Clinicopathologic data of 135 patients with clinical stage IA2 to IIA2 cervical cancer treated with PORT from 2001 to 2012 were reviewed, retrospectively. Postoperative parametrial resection margin (PRM) and vaginal resection margin (VRM) were investigated separately. The median treatment dosage of external beam radiotherapy (EBRT) to the whole pelvis was 50.4 Gy in 1.8 Gy/fraction. High-dose-rate vaginal brachytherapy after EBRT was given to patients with positive or close VRMs. Concurrent platinum-based chemoradiotherapy (CCRT) was administered to 73 patients with positive resection margin, lymph node (LN) metastasis, or direct extension of parametrium. Kaplan-Meier method and log-rank test were used for analyzing LRR, DM, and OS; Cox regression was applied to analyze prognostic factors. The 5-year disease-free survival was 79% and 5-year OS was 91%. In univariate analysis, positive or close PRM, LN metastasis, direct extension of parametrium, lymphovascular invasion, histology of adenocarcinoma, and chemotherapy were related with more DM and poor OS. In multivariate analysis, PRM and LN metastasis remained independent prognostic factors for OS. PORT after radical hysterectomy in uterine cervical cancer showed excellent OS in this study. Positive or close PRM after radical hysterectomy in uterine cervical cancer correlates with poor prognosis even with CCRT. Therefore, additional treatments to improve local control such as radiation boosting need to be considered.

    Full Text Available Today, the common term metabolic syndrome encompasses visceral (abdominal obesity, glucose intolerance, type 2 diabetes mellitus (DM, hypertension, and dyslipidemia. In Europe, the rate of obesity mong the women ranges from 6 to 36 %. In the USA, 65 % of the adult population is overweight and 30 % is obese. High estrogen production in adipose tissue in patients with obesity has been established to increase the risk of cancer of the corpus uteri (CCU by 4 times as compared to that in normal weight female patients. Furthermore, obese patients are at increased risk for DM that is also a risk factor for CCU. A rise in the number of obese patients leads to the population redistribution of gynecological cancer. The increasing number of patients with gynecological cancer is overweight. This patient group has an increased risk from surgery and anesthesia, a higher incidence of postoperative complications, and delayed recovery. Laparotomy increases the duration of hospital stay and the rate of wound complications. The frequency of urologic injuries in obese patients varies between 2 and 4 %. In this patient category, the rate of damage to the large vessels or bowels has also statistically significant differences. The literature highlights a number of complications specific to patients with obesity: trocar damage to anterior abdominal wall vessels, particularly to the inferior epigastric artery, urinary bladder, as well as trocar site hernia. The authors describe their experience in treating CCU patients with metabolic syndrome at the Department of Surgery for Female Reproductive System Tumors, N. N. Blokhin Russian Cancer Research Center. They demonstrate that laparoscopic extirpation of the uterus and its appendages can be performed in patients with third-degree obesity (weighing 174 kg in Stage I CCU. It should be noted that this weight was previously regarded as an absolute contraindication to surgical treatment.

    Introduction The raw incidence of cancer of the uterine cervix is Spain is 7,8 per 100.000 inhabitants (adjusted incidence is 5.6). The incidence of this tumor is still low, but a steady increase has been seen, probably related to increasing risk factors. Aim To determine the frequency of infection by different types of human papillomavirus (HPV) in Papanicolau smears from women with and without cancer of the uterine cervix in Spain. Patients and methods A case-control study was performed in women with and without cervical cancer from Zaragoza, Spain. Pap smears from 600 cases (540 women with cervical intraepithelial neoplasms (CIN) and 60 with invasive cancer) and 1200 controls (women without those lesions) were tested by polymerase chain reaction (PCR) and typed by oligonucleotide microarray-based detection. Results HPV was detected in 93.3% of all samples with invasive cancer versus 17.5% of controls. OR for invasive cancer was 55 (95% CI 21.5–140,5). Statistically significant associations were also found for different grades of cervical dysplasia. Conclusion The strong association found between HPV infection, specifically types 16 and 18 and cancer of the uterine cervix in Zaragoza, Spain, stresses the importance of ongoing efforts to institute a vaccine program with recently approved HPV vaccines in order to prevent cervical cancer in this population.

    The continued increase in incidence of some hormone-related cancers worldwide is of great concern. Although estrogen-like substances in the environment were blamed for this increase, the possible role of endogenous estrogens from food has not been widely discussed. We are particularly concerned about cows' milk, which contains a considerable quantity of estrogens. When we name cows' milk as one of the important routes of human exposure to estrogens, the general response of Western people is that "man has been drinking cows' milk for around 2000 years without apparent harm." However, the milk that we are now consuming is quite different from that consumed 100 years ago. Unlike their pasture-fed counterparts of 100 years ago, modern dairy cows are usually pregnant and continue to lactate during the latter half of pregnancy, when the concentration of estrogens in blood, and hence in milk, increases. The correlation of incidence and mortality rates with environmental variables in worldwide countries provides useful clues to the etiology of cancer. In this study, we correlated incidence rates for breast, ovarian, and corpus uteri cancers (1993-97 from Cancer Incidence in Five Continents) with food intake (1961-97 from FAOSTAT) in 40 countries. Meat was most closely correlated with the breast cancer incidence (r=0.827), followed by milk (0.817) and cheese (0.751). Stepwise multiple-regression analysis (SMRA) identified meat as the factor contributing most greatly to the incidence of breast cancer ([R]=0.862). Milk was most closely correlated with the incidence of ovarian cancer (r=0.779), followed by animal fats (0.717) and cheese (0.697). SMRA revealed that milk plus cheese make the greatest contribution to the incidence of ovarian cancer ([R]=0.767). Milk was most closely correlated with corpus uteri cancer (r=0.814), followed by cheese (0.787). SMRA revealed that milk plus cheese make the most significant contribution to the incidence of corpus uteri cancer ([R]=0

    To determine if preoperative [{sup 18}F]FDG-PET/CT imaging has prognostic significance in patients with uterine cervical cancer. Patients with FIGO stage IB to IIA cervical cancer were imaged with integrated FDG PET/CT before radical surgery. The relationship between the maximum standardized uptake value (SUV{sub max}) of FDG in the primary tumour during PET/CT and recurrence was examined. Included in the study were 75 patients. Medical records including clinical data, treatment modalities, and treatment results were retrospectively reviewed. The median duration of follow-up was 13 months (range 3 to 58 months) after treatment. Median preoperative SUV{sub max} values in the primary tumours were significantly higher in patients with higher FIGO stages (p = 0.0149), pelvic lymph node metastasis (p = 0.0068), parametrial involvement (p = 0.0002), large (>4 cm) tumour size (p = 0.0022), presence of lymphovascular space invasion (p = 0.0055), and deep cervical stromal invasion (p < 0.0001). In univariate analysis, lymph node metastasis, parametrial invasion, presence of lymphovascular space invasion, and preoperative SUV{sub max} (uncategorized values) in the primary tumour were significantly associated with recurrence. However, in multivariate analysis, preoperative SUV{sub max} (p = 0.014, HR 1.178, 95% CI 1.034-1.342), age (p = 0.021, HR 0.87, 95% CI 0.772-0.980), and parametrial involvement (p = 0.040, HR 27.974, 95% CI 1.156-677.043) by primary tumour were significantly associated with recurrence. Preoperative FDG uptake by the primary tumour showed a significant association with recurrence in patients with uterine cervical cancer. (orig.)

    We prospectively collected data on all patients with stage IB1 cervical cancer, who underwent total laparoscopic radical hysterectomy with the use of a modified uterine manipulator. From January 2000 to December 2005, 54 patients met the study criteria. The mean age was 41.8 +/- 7.47 years. Average BMI (kg/m(2)) was 27.38 +/- 3.13. Squamous carcinoma and adenocarcinoma were found in 88.88% and 11.11% of the cases, respectively. The average surgical time was 265 +/- 70.8 min. The mean estimated blood loss was 276.11 +/- 123.03 ml. The average patient lymph node count was 19.64 +/- 5.08. Positive malignant lymph nodes were identified in 11.11% of the cases. Surgical margins were free of disease in all patients. The mean hospital stay was 1.5 +/- 1 days. There was no mortality. Total laparoscopic radical hysterectomy can be considered a safe alternative to laparotomy. The use of a uterine manipulator does not pose an increased surgical risk and allows for a simpler and more feasible procedure.

    The nodal status is the strongest prognostic factor in early stage cancers. The sentinel-lymph node (S.L.N.) is defined as the first draining lymph node of an organ; the lymph node status is determined by the histological results of S.L.N.. The lymphadenectomy, with high morbidity, is realised only in case of metastatic S.L.N.. The S.L.N. identification, in most of cases, is performed using the combination of blue dye and radiocolloid {sup 99m}Tc injections. The purpose of this article is to give some practical details about the S.L.N. isotopic procedure in breast cancer, vulva and penile cancer, uterine cervix and prostate cancer. (author)

    Introduction The sentinel node technique (S.N.) was proposed in cervical cancers in order to optimise the diagnosis of metastases and the lymphatic micrometastases in the early stages while avoiding useless wide clearings out. The identification of this node is done by injection of a dye and/or a radioactive colloid and its ablation for pathological examination. Patients and methods We report the case of three patients followed for a uterine cancer having benefited from a lymphoscintigraphy before surgery. During the surgical procedure, the detection of the sentinel node was carried out after cervical injection of blue dye and using a gamma detection probe. Results The lymphoscintigraphy was positive for two cases with a positive detection for the three cases during the operation. The pathological study revealed a node metastasis for one case. The technical of the sentinel node applied to uterine cancers appears realizable essentially for uterine cancers of early stage (I). However the risk of false negative can be observed in advanced cancer (III), as it is the case of our patient having a negative lymphoscintigraphy. Conclusion The nuclear medicine is important in the detection of the sentinel node of various cancers, uterine cancer included, thus allowing an appropriate cardiologic management. (authors)

    Full Text Available Abstract Background Uterine serpins are members of the serine proteinase inhibitor superfamily. Like some other serpins, these proteins do not appear to be functional proteinase inhibitors. The most studied member of the group, ovine uterine serpin (OvUS, inhibits proliferation of several cell types including activated lymphocytes, bovine preimplantation embryos, and cell lines for lymphoma, canine primary osteosarcoma and human prostate cancer (PC-3 cells. The goal for the present study was to evaluate the mechanism by which OvUS inhibits cell proliferation. In particular, it was tested whether inhibition of DNA synthesis in PC-3 cells involves cytotoxic actions of OvUS or the induction of apoptosis. The effect of OvUS in the production of the autocrine and angiogenic cytokine interleukin (IL-8 by PC-3 cells was also determined. Finally, it was tested whether OvUS blocks specific steps in the cell cycle using both PC-3 cells and lymphocytes. Results Recombinant OvUS blocked proliferation of PC-3 cells at concentrations as low as 8 μg/ml as determined by measurements of [3H]thymidine incorporation or ATP content per well. Treatment of PC-3 cells with OvUS did not cause cytotoxicity or apoptosis or alter interleukin-8 secretion into medium. Results from flow cytometry experiments showed that OvUS blocked the entry of PC-3 cells into S phase and the exit from G2/M phase. In addition, OvUS blocked entry of lymphocytes into S phase following activation of proliferation with phytohemagglutinin. Conclusion Results indicate that OvUS acts to block cell proliferation through disruption of the cell cycle dynamics rather than induction of cytotoxicity or apoptosis. The finding that OvUS can regulate cell proliferation makes this one of only a few serpins that function to inhibit cell growth.

    The thyroid gland is a relatively uncommon site for a metastatic disease, although it is richly supplied with blood. The metastases may originate from various primary sites, mainly kidney, lung, head and neck, and breast. Thyroid metastasis from cervical carcinomas is extremely rare; and only a few cases have been previously reported in the literature. In patient with thyroid nodules and an oncological history, the possibility of thyroid metastasis should be seriously considered. Despite the rarity of the metastasis of cervical carcinoma to the thyroid, it is difficult to say appropriate treatment approach for these lesions. When managing such patients, decision-making should balance the possibility of gaining long-term survival against estimation of the aggressiveness of the disease and its possible complications. Here, a case of thyroid metastasis from a squamous cell carcinoma of the uterine cervix presenting with cervical mass and difficulty in swallowing and its treatment is reported.

    Patient: Female, 53 Final Diagnosis: Endometrial stromal sarcoma Symptoms: Abdominal distension Medication: — Clinical Procedure: — Specialty: Oncology Objective: Rare co-existance of disease or pathology Background: Paraneoplastic hypercalcemia is a well-described complication associated with a variety of malignancies. However, its incidence in gynecological malignancies is low. Case Report: A 53-year-old woman presented with progressive abdominal distention and irregular vaginal bleeding of several weeks’ duration. A contrast CT abdomen and pelvis was significant for a mass in the lower uterine/cervical region, multiple peritoneal and omental masses, enlarged pelvic and paraaortic lymph nodes, and large-volume ascites. A pelvic exam revealed a fungating vaginal mass, with biopsy showing a high-grade tumor with immunohistochemical staining positive for vimentin, CD10, and cyclin D1, consistent with endometrial stromal sarcoma. During her hospitalization, the patient became increasingly lethargic. Workup showed severe hypercalcemia and evidence of acute kidney injury. The patient did not have evidence of bony metastatic disease on imaging studies. Further laboratory evaluation revealed an elevated PTHrP of 301 pg/mL (nl 14–27), a depressed PTH level of 3 pg/mL (nl 15–65), and a depressed 25-OH vitamin D level of 16 ng/mL (nl 30–100), consistent with humoral hypercalcemia of malignancy. The patient was treated with pamidronate, calcitonin, and intravenous fluids. She eventually required temporary hemodialysis and denosumab for refractory hypercalcemia, which improved her electrolyte abnormalities and clinical status. Conclusions: Uterine malignancies of various histologies are increasingly recognized as a cause of humoral hypercalcemia. They are an important differential diagnosis in a woman with hypercalcemia and abnormal vaginal bleeding or abdominal symptoms. PMID:28057913

    Purpose To evaluate tumor shrinking kinetics in order to implement image-guided brachytherapy (IGBT) for the treatment of patients with cervix cancer. Material and methods This study has prospectively evaluated tumor shrinking kinetics of thirteen patients with uterine cervix cancer treated with combined chemoradiation. Four high dose rate brachytherapy fractions were delivered during the course of pelvic external beam radiation therapy (EBRT). Magnetic resonance imaging (MRI) exams were acquired at diagnosis (D), first (B1), and third (B3) brachytherapy fractions. Target volumes (GTV and HR-CTV) were calculated by both the ellipsoid formula (VE) and MRI contouring (VC), which were defined by a consensus between at least two radiation oncologists and a pelvic expert radiologist. Results Most enrolled patients had squamous cell carcinoma and FIGO stage IIB disease, and initiated brachytherapy after the third week of pelvic external beam radiation. Gross tumor volume volume reduction from diagnostic MRI to B1 represented 61.9% and 75.2% of the initial volume, when measured by VE and VC, respectively. Only a modest volume reduction (15-20%) was observed from B1 to B3. Conclusions The most expressive tumor shrinking occurred in the first three weeks of oncological treatment and was in accordance with gynecological examination. These findings may help in IGBT implementation. PMID:27648083

    Cervical cytology for uterine cervical cancer screening has transitioned from conventional smear (CS) to liquid-based cytology (LBC), which has many advantages. The aim of this study was to compare the proportion of unsatisfactory specimens from CS versus LBC at multiple institutions including general hospitals and commercial laboratories. Each participating institution provided a minimum of 500 Papanicolaou (Pap) test results for analysis. Pap tests were classified according to the participating institution (commercial laboratory or general hospital) and the processing method (CS, ThinPrep, SurePath, or CellPrep). The causes of unsatisfactory results were classified as technical problems, scant cellularity, or complete obscuring factors. A total of 38,956 Pap test results from eight general hospitals and three commercial laboratories were analyzed. The mean unsatisfactory rate of LBC was significantly lower than that of CS (1.26% and 3.31%, p = .018). In the LBC method, samples from general hospitals had lower unsatisfactory rates than those from commercial laboratories (0.65% vs 2.89%, p = .006). The reasons for unsatisfactory results were heterogeneous in CS. On the other hand, 66.2% of unsatisfactory results in LBC were due to the scant cellularity. Unsatisfactory rate of cervical cancer screening test results varies according to the institution and the processing method. LBC has a significantly lower unsatisfactory rate than CS.

    The aim of this study was to determine the impact of obesity on the rate of successful sentinel lymph node (SLN) mapping in patients with uterine cancer undergoing robotic surgery, and compare SLN detection rates using indocyanine green (ICG) versus blue dye. We reviewed robotic cases undergoing SLN mapping with a cervical injection from January 2011 to December 2013 using either blue dye or ICG with near-infrared (NIR) fluorescence imaging. Data were stratified by body mass index (BMI) and the dye used. Appropriate statistical tests were applied. Overall, 472 cases were identified. Bilateral mapping was successful in 352 cases (75 %), and unilateral mapping was successful in 73 cases (15 %). Bilateral mapping was achieved in 266 (85 %) of 312 ICG cases compared with 86 (54 %) of 160 blue-dye cases (p cancer. Successful mapping decreases with increasing BMI irrespective of the dye used; however, it is significantly improved with the use of ICG and NIR fluorescence imaging compared with blue dye.

    Full Text Available BACKGROUND: Uterine blood flow is an important factor in uterine viability, but the number of blood vessels required to maintain viability is uncertain. In this study, indocyanine green (ICG fluorescence imaging was used to examine uterine hemodynamics and vessels associated with uterine blood flow in cynomolgus macaque. METHODS: The uterus of a female cynomolgus macaque was cut from the vaginal canal to mimic a situation during trachelectomy or uterine transplantation surgery in which uterine perfusion is maintained only with uterine and ovarian vessels. Intraoperative uterine hemodynamics was observed using ICG fluorescence imaging under conditions in which various nutrient vessels were selected by clamping of blood vessels. A time-intensity curve was plotted using imaging analysis software to measure the T(max of uterine perfusion for selected blood vessel patterns. Open surgery was performed with the uterus receiving nutritional support only from uterine vessels on one side. The size of the uterus after surgery was monitored using transabdominal ultrasonography. RESULTS: The resulting time-intensity curves displayed the average intensity in the regions of the uterine corpus and uterine cervix, and in the entire uterus. Analyses of the uterine hemodynamics in the cynomolgus macaque showed that uterine vessels were significantly related to uterine perfusion (P=0.008, whereas ovarian vessels did not have a significant relationship (P=0.588. When uterine vessels were clamped, ovarian vessels prolonged the time needed to reach perfusion maximum. Postoperative transabdominal ultrasonography showed that the size of the uterus was not changed 2 months after surgery, with recovery of periodic menstruation. The cynomolgus macaque has got pregnant with favorable fetus well-being. CONCLUSION: Uterine vessels may be responsible for uterine blood flow, and even one uterine vessel may be sufficient to maintain uterine viability in cynomolgus macaque. Our

    This study aimed to evaluate the association between risk factors for uterine cervical neoplasms and cervical lesions by HPV by comparison of the visual inspection with acetic acid (VIA), cytology and cervicography results. A prevalence research was made with 157 women in a health center of Fortaleza in the period of June to September 2006. The SPSS program was used to codify the data. Inferences were made through statistical tests (chi2 = chi square and LR = likelihood ratio). The VIA, cervicography and cytology obtained 43.3%, 10.19% and 3.2% of altered results. The variables with important association to cervical lesions in the VIA were: aged less than 20 years old (p = 0.0001); one or more partners in the last three months (p = 0.015); use of contraceptives (p = 0.0008); presence of vaginal discharge (p = 0.0001) and moderate or accentuated inflammatory process (p = 0.0001). In the cytology: low instructional level (p = 0.0001) and high pH (p = 0.001). It wasn't found any significant association in the cervicography.

    A 65-year-old woman had received a panhysterectomy and radiation therapy for a uterine cancer in 1974 and underwent a drainage operation for a peritonitis due to rupture of the bladder associated with radiation cystitis in 1983. A rectovesical fistula was revealed and partial resection of the bladder and rectum was performed in 1996. In 1998, rectovesical fistula recurred and symptom of fecaluria and contact-type dermatitis at perineal region subsequently worsened. In February, 2000, colonoscopy and gastrograffin-enema revealed a giant recto-vagino-vesical fistula. Although we recommended ileostomy, the patient refused our offer. She gave informed consent to our proposal about the insertion of a covered expandable metallic stent (EMS) into the rectum to treat for fecaluria. After insertion of a covered EMS, fecaluria and contact-type dermatitis at perineal region subsequently improved. Three months later, fecaluria appeared again. Finally, seven months later, severe inflammation occurred at perineal and pubic region because of migration of the covered EMS into the bladder, then we removed the covered EMS and performed ileostomy. It is difficult to use the covered EMS treatment for benign rectovesical or rectovaginal fistula for a long term. (author)

  11. Interobserver variation in rectal and bladder doses in orthogonal film-based treatment planning of cancer of the uterine cervix

    2008-01-01

    Full Text Available Orthogonal film-based treatment planning is the most commonly adopted standard practice of treatment planning for cancer of the uterine cervix using high dose rate brachytherapy (HDR. This study aims at examining the variation in rectal and bladder doses when the same set of orthogonal films was given to different observers. Five physicists were given 35 pairs of orthogonal films obtained from patients who had undergone HDR brachytherapy. They were given the same instructions and asked to plan the case assuming the tumor was centrally placed, using the treatment-planning system, PLATO BPS V13.2. A statistically significant difference was observed in the average rectal (F = 3.407, P = 0.01 and bladder (F = 3.284, P = 0.013 doses and the volumes enclosed by the 100% isodose curve ( P < 0.01 obtained by each observer. These variations may be attributed to the differences in the reconstruction of applicators, the selection of source positions in ovoids and the intrauterine (IU tube, and the differences in the selection of points especially for the rectum, from lateral radiographs. These variations in planning seen within a department can be avoided if a particular source pattern is followed in the intrauterine tube, unless a specific situation demands a change. Variations in the selection of rectal points can be ruled out if the posterior vaginal surface is clearly seen.

    Objective The aim of this study was to investigate the ability of intravoxel incoherent motion (IVIM) dif usion-weighted magnetic resonance imaging (MRI) to diagnose cervical cancer and to evaluate the response of uterine cervical cancer to radiochemotherapy (CRT). Methods This prospective study was approved by the institutional review board, and informed consent was obtained from al patients. A total of 23 patients with primary cervical cancer who were undergoing CRT and 16 age-matched healthy subjects were prospectively recruited for IVIM (b = 0–800 s/mm2) and stan-dard pelvic MRI. Bi-exponential analysis was performed to derive f (perfusion fraction), D* (pseudo-dif usion coef icient), and D (true molecular dif usion coef icient) in cervical cancer (n = 23) and the normal cervix (n= 16). The apparent dif usion coef icient (standard ADC) was calculated. The independent-samples t-test and paired-samples t-test were used for comparisons. Results Pre-treatment cervical cancer had the lowest standard ADC (1.15 ± 0.13 × 10-3 mm2/s) and D (0.89 ± 0.10 × 10-3 mm2/s) values, and these were significantly dif erent from the normal cervix and post-treatment cervical cancer (P = 0.00). The f (16.67 ± 5.85%) was lowest in pre-treatment cervical cancer and was significantly dif erent from the normal cervix and post-treatment cervical cancer (p = 0.012 and 0.00, respectively). No dif erence was observed in D*. Conclusion IVIM is potential y promising for dif erentiating between the normal cervix and cervical can-cer because pre-treated cervical cancer has low perfusion and dif usion IVIM characteristics. Further, the standard ADC, D, and f of cervical cancer showed a tendency to normalize after CRT; thus, IVIM may be useful for monitoring the response to CRT in cervical cancer.

    Background: In clinical cancer research of morbidity, low associations between clinician-assessed toxicity/morbidity and patient-reported symptoms are consistently described in the literature. While morbidity grading systems are supposed to follow more or less objective criteria, patient reported symptoms inherently are based on a subjective self-evaluation of the impact on quality of life. The aim of this study was to focus on major discrepancies with high clinical relevance and to evaluate its impact with regard to underreporting of morbidity. Material and methods: Early morbidity assessed by clinicians with CTCAEv.3 and patient reported quality of life (EORTC-QLQ-C30/CX24) were compared regarding 12 overlapping symptoms in 223 patients with uterine cervical cancer 3 months after definitive radio(chemo)therapy in the ongoing EMBRACE study. Mismatches showing discrepancies between both grading systems were classified, if patients reported substantial symptoms (quite a bit/very much) and CTCAE grading was rated G0. Results: In total, 360 substantial symptoms were reported by patients by EORTC-QLQ; 159 (44%) of those were not recognized by CTCAE. Symptoms with the highest occurrence of mismatches overall are urinary frequency, fatigue, and insomnia. Large institutional differences were found, showing two centers with 4 vs. 71% of patients with at least one mismatch. Conclusion: Analysis of mismatches indicated a high risk of underestimation of early morbidity. Thus, nearly half of the patient-reported substantial symptoms were not recognized by CTCAE scoring (G0) 3 months after treatment. Prospective assessment of morbidity in clinical studies should, therefore, integrate patient reported symptoms to receive a complete and comprehensive picture. (orig.)

    Objective The purpose of this study was to compare the long-term safety, disease-free survival, and recurrence rate of total laparoscopic hysterectomy using uterine manipulator and abdominal hysterectomy in the surgical treatment in early-stage endometrial cancer. Study Design This was a cohort study of 147 patients with clinical endometrial cancer (laparoscopic surgery group, 77 women; laparotomy group, 70 women). Data were evaluated and analyzed by intention-to-treat principle, and survival data of stage I endometrial cancer (129 patients; 66 from laparoscopic surgery group and 60 from laparotomy group) were estimated by using the Kaplan-Meier curves. Results After a follow-up period of 60 months for both laparoscopic surgery and laparotomy groups, no significant difference in the cumulative recurrence rates (7.4% and 13.1%, P = 0.091) and overall survival (97.1% and 95.1%, P = 0.592) was detected between both groups of stage I endometrial cancer. Conversion to laparotomy occurred in 10.4% (8/77) of the laparoscopic procedures. Laparoscopic hysterectomy was associated with less use of pain medication (P = 0.001) and a shorter hospital stay (P manipulators did not have increased recurrence rate in patients treated with laparoscopic approach. Conclusions The laparoscopic surgery approach to early-stage endometrial cancer using uterine manipulators is as safe and effective as the laparotomic approach. PMID:27518143

    This study aims to assess use of hormone therapy (HT) after cervical cancer treatment in women of premenopause age. We identified 837 women aged 45 years or younger at diagnosis of cervical cancer in the Swedish Cancer Register from January 1, 2005 to September 30, 2009 with a minimal follow-up of 1.5 years. Information on cancer treatment (surgical operation, radiotherapy, and/or chemotherapy) was obtained through the National Patient Register. Use of HT was estimated through HT dispensing during follow-up as recorded in the Prescribed Drug Register. Percentage of recommended dose was assessed by frequency of HT dispensing at half-year intervals up to April 1, 2011 or a maximal age of 50 years. A total of 257 women (31%) received acute estrogen deprivation due to bilateral salpingo-oophorectomy and/or radiotherapy. Among these women, 171 (67%) of 257 had at least one dispensing of HT during the period 0.5 to 1 year after diagnosis, and 118 (46%) of 257 were dispensed 75% or more of the recommended dose. Proportion users decreased to 39% at 4.5 to 5 years after diagnosis (21% with ≥ 75% of the recommended dose). Women younger than 40 years had a higher prevalence of HT use at 0.5 to 1 year (79%), decreasing to 45% after 4.5 to 5 years. The results did not vary by cancer histology. Fewer than half of cervical cancer survivors with therapy-induced early menopause used HT at or close to the recommended dose, and the use decreased during follow-up. Increased awareness of the health benefits of HT for this patient group is needed among professionals and women.

    Cyclooxygenase (COX)-2 inhibitors have been reported to potentially modulate the resistance of cancer cells to chemotherapeutic drugs by affecting multidrug resistance 1 (MDR1) expression. In the present study, we investigated the association between COX-2 and MDR1 expression in endometrial cancers and evaluated the effects of the COX-2 inhibitor, etodolac, in combination with paclitaxel on paclitaxel-resistant endometrial cancer cells. The relationship between COX-2 and MDR1 mRNA expression was examined by quantitative PCR in 36 endometrial cancer specimens. The paclitaxel-resistant cell line OMC-2P was established from OMC-2 cells. Paclitaxel (1 µg/ml) with or without etodolac (10 µg/ml) was added to OMC-2 and OMC-2P cells, and COX-2 and MDR1 mRNA expression levels were examined. The concentration of prostaglandin E2 (PGE2) in the supernatant of each cell line was examined by enzyme-linked immunosorbent assay. The function of MDR1 was determined by intracellular accumulation of rhodamine 123 using flow cytometry, and the concentration of intracellular paclitaxel was determined by high-performance liquid chromatography. We found a positive relationship between COX-2 and MDR1 mRNA expression in endometrial cancer. Both COX-2 mRNA expression and PGE2 production were elevated in resistant OMC-2P cells when compared to non-resistant OMC-2 cells. Additionally, MDR1 mRNA expression was markedly upregulated in OMC-2P cells. In OMC-2 cells, COX-2 and MDR1 mRNA levels were significantly upregulated by paclitaxel treatment and downregulated by co-administration with etodolac. In OMC-2P cells, COX-2 mRNA expression was also significantly upregulated by paclitaxel treatment and tended to be downregulated by co-administration with etodolac. Moreover, co-administration of paclitaxel and etodolac suppressed the induction of MDR1 mRNA. Rhodamine 123 efflux was increased in OMC-2P cells when compared to the efflux in the OMC-2 cells and was increased in response to paclitaxel

    Full Text Available Abstract Background It has been hypothesised that increased VEGF-D expression may be an independent prognostic factor for endometrial cancer progression and lymph node metastasis; however, the mechanism by which VEGF-D may promote disease progression in women with endometrial cancer has not been investigated. Our aim was to describe the distribution of lymphatic vessels in mouse uterus and to examine the effect of VEGF-D over-expression on these vessels in a model of endometrial cancer. We hypothesised that VEGF-D over-expression would stimulate growth of new lymphatic vessels into the endometrium, thereby contributing to cancer progression. Methods We initially described the distribution of lymphatic vessels (Lyve-1, podoplanin, VEGFR-3 and VEGF-D expression in the mouse uterus during the estrous cycle, early pregnancy and in response to estradiol-17beta and progesterone using immunohistochemistry. We also examined the effects of VEGF-D over-expression on uterine vasculature by inoculating uterine horns in NOD SCID mice with control or VEGF-D-expressing 293EBNA tumor cells. Results Lymphatic vessels positive for the lymphatic endothelial cell markers Lyve-1, podoplanin and VEGFR-3 profiles were largely restricted to the connective tissue between the myometrial circular and longitudinal muscle layers; very few lymphatic vessel profiles were observed in the endometrium. VEGF-D immunostaining was present in all uterine compartments (epithelium, stroma, myometrium, although expression was generally low. VEGF-D immunoexpression was slightly but significantly higher in estrus relative to diestrus; and in estradiol-17beta treated mice relative to vehicle or progesterone treated mice. The presence of VEGF-D over-expressing tumor cells did not induce endometrial lymphangiogenesis, although changes were observed in existing vessel profiles. For myometrial lymphatic and endometrial blood vessels, the percentage of profiles containing proliferating

    Cervical cancer has been identified as the third leading cause of average years of life lost per person dying of cancer. Since essentially all cervical cancers contain copies of human papillomavirus (HPV) DNA, we propose a treatment that targets HPV-infected cells using strategies that re-introduce normal functions into the infected cells while sparing healthy cells. We propose the use of focused ultrasound in combination with microbubbles as means to deliver antibodies against the E6 protein present only in HPV positive cells. We conducted in vitro studies with cell cultures of SiHa cervical carcinoma cells seeded into Opticell™ chambers. An in-house ultrasound excitation apparatus was used to control and explore the optimal acoustic parameters in order to maximize delivery. We first validated the possibility of delivering the EX-EGFP-M02 vector (Genecopoeia) into the cells; 1.2 μL of activated microbubbles (Definity®) and 50 μg of the vector were mixed in media and then injected into the Opticell™ chamber. We used 32 μs pulses at a central frequency of 930 KHz with a repetition frequency of 1.5 kHz and total exposure duration of 30 s; six pressure values were tested (0 to 1 MPa). Fluorescence imaging was used to determine the levels of intracellular proteins and assess delivery. The delivery of an anti-α-Tubulin antibody was next tested and confirmed that the delivery into HPV16 positive cells was successful.

    Estrogen-related receptor (ERR)α presents structural similarities with estrogen receptor (ER)α. However, it is an orphan receptor not binding to naturally occurring estrogens. This study was designed to investigate the role of ERRα in endometrial cancer progression. Immunohistochemistry analysis on 50 specimens from patients with endometrial cancer showed that ERRα was expressed in all examined tissues and the elevated expression levels of ERRα were associated with advanced clinical stages and serous histological type (p < 0.01 for each). ERRα knockdown with siRNA suppressed angiogenesis via VEGF and cell proliferation in vitro (p < 0.01). Cell cycle and apoptosis assays using flow cytometry and western blot revealed that ERRα knockdown induced cell cycle arrest during the mitotic phase followed by apoptosis initiated by caspase-3. Additionally, ERRα knockdown sensitized cells to paclitaxel. A significant reduction of tumor growth and angiogenesis was also observed in ERRα knockdown xenografts (p < 0.01). These findings indicate that ERRα may serve as a novel molecular target for the treatment of endometrial cancer. PMID:27153547

    About 30% of endometrial cancer (EC) patients are diagnosed at an advanced stage of the disease, which is associated with a drastic decrease in the 5-year survival rate. The identification of biomarkers in uterine aspirate samples, which are collected by a minimally invasive procedure, would improve early diagnosis of EC. We present a sequential workflow to select from a list of potential EC biomarkers, those which are the most promising to enter a validation study. After the elimination of confounding contributions by residual blood proteins, 52 potential biomarkers were analyzed in uterine aspirates from 20 EC patients and 18 non-EC controls by a high-resolution accurate mass spectrometer operated in parallel reaction monitoring mode. The differential abundance of 26 biomarkers was observed, and among them ten proteins showed a high sensitivity and specificity (AUC > 0.9). The study demonstrates that uterine aspirates are valuable samples for EC protein biomarkers screening. It also illustrates the importance of a biomarker verification phase to fill the gap between discovery and validation studies and highlights the benefits of high resolution mass spectrometry for this purpose. The proteins verified in this study have an increased likelihood to become a clinical assay after a subsequent validation phase.

    Perfusion lymphoscintigraphy was performed by subcutaneous injection of 7.4 MBq (0.2mCi) {sup 99m}Tc-human serum albumin ({sup 99m}Tc-HSA) on 18 patients with uterine cancer treated by operation and/or irradiation. Radioactivity at the injection site was counted for 3 min at 10 min (a) and at 3 hr (b) after injection, and the clearance of {sup 99m}Tc-HSA was defined as (1-(b)/(a)) x 100(%) ((a) and (b) were corrected for decay of the isotope). The clearance in 6 legs with lymphedema was significantly more delayed than that in 16 legs without lymphedema in the patients treated with both surgery and irradiation (16.6 +- 7.7% vs 34.9 +- 9.3%: P< 0.01). The clearances in edematous legs in a case which had developed a venous occulusion after operation were 44.2% and 41.7%, which were almost the same as those in the non-edematous patients treated with surgery alone. The clearance in patients treated with both operation and irradiation was significantly more delayed than that in patients treated with the signle modality of operation or irradiation (29.7 +- 11.9% vs 41.1 +- 7.2%, 44.5 +- 7.7%, respectively: P< 0.01). These data suggest that perfusion lymphoscintigraphy using {sup 99m}Tc-HSA is useful for evaluating patients with lymphedema and for differentiating it from edema caused by other mechanisms.

    Perfusion lymphoscintigraphy was performed by subcutaneous injection of 7.4 MBq (0.2 mCi) {sup 99m}Tc-human serum albumin ({sup 99m}Tc-HSA) in 25 patients with uterine cancer treated by operation and/or irradiation. Radioactivity at the injection site was counted for 3 min at 10 min (a) and at 3 hr (b) after injection, and the clearance of {sup 99m}Tc-HSA was defined as (1-(b)/(a))x100(%) ((a) and (b) were corrected for decay of the isotope). The clearance in legs with lymphedema was significantly more delayed than those in legs without lymphedema in patients treated with both operation and irradiation (16.6{+-}7.7% vs 34.9{+-}9.3%; p<0.01) and in patients treated with radiation therapy alone (33.1{+-}7.4 vs 48.0{+-}5.6; p<0.01). The clearances in edematous legs in a case which had developed venous occulusion after operation were 44.2% and 41.7%, which were almost the same as those in the non-edematous patients treated with operation alone. Clearance in patients treated with both operation and irradiation were significantly more delayed than those in patients treated with a single modality of operation or irradiation (30.1{+-}11.4% vs 41.9{+-}8.9%, 42.0{+-}9.7%, respectively; p<0.01). Radiation doses at points B were well correlated with clearance of {sup 99m}Tc-HSA (p<0.05). These data suggest that perfusion lymphoscintigraphy using {sup 99m}Tc-HSA is useful for evaluating the patients with lymphedema and for differentiating it from the edema caused by the other mechanisms. It is also suggested that radiation dose is one of factors in the occurrence of lymphedema. (author).

    Full Text Available Background. Three nomogram models for early stage uterine cervical cancer have been developed (KROG 13-03 for overall survival [OS], SNUH/AMC for disease-free survival [DFS], and KROG 12-08 for distant metastases-free survival [DMFS] after radical hysterectomy (RH and pelvic lymph node dissection (PLND. This study aimed to validate these models using our cohort with adjuvant radiotherapy. Methods. According to the eligibility criteria of nomogram studies, patients were enrolled in Group A (N=109 for the two KROG models (RH with PLND and whole pelvic irradiation and Group B (N=101 for the SNUH/AMC model (RH with PLND and squamous histology. Using Cox-regression hazard models, the prognostic factors of our cohorts were evaluated. The risk probabilities induced from published nomogram scores were calculated and the concordance indices were evaluated. Results. Group A had 88.1% 5-year OS and 86.0% 5-year DMFS. Group B had 83.0% 5-year DFS. In multivariate analyses, large tumor size for OS (HR 8.62, P<0.001 and DMFS (HR 5.13, P=0.003, young age (≤40 versus 41–64 years for OS (HR 4.63, P=0.097 and DFS (HR 3.44, P=0.051, and multiple lymph node metastases (0 versus ≥3 for DMFS (HR 4.03, P=0.031 and DFS (HR 3.90, P=0.038 were significantly correlated. The concordance indices for OS, DMFS, and DFS were 0.612 (P=0.002, 0.597 (P=0.014, and 0.587 (P=0.020, respectively. Conclusion. The developed nomogram models after RH and PLND are clinically useful in predicting various types of survival with significance.

    The purpose is to evaluate the accuracy of integrated {sup 18}F-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) with intravenous contrast medium in detecting pelvic and paraaortic lymph node metastasis in patients with uterine cancer, with surgical and histopathological findings used as the reference standard. Forty-five patients with endometrial or uterine cervical cancer underwent radical hysterectomy, including pelvic lymphadenectomy with or without paraaortic lymphadenectomy, after PET/CT. PET/CT findings were interpreted by two experienced radiologists in consensus. The criterion for malignancy on PET/CT images was increased tracer uptake by the lymph node, independent of node size. The overall node-based sensitivity, specificity, PPV, NPV and accuracy of PET/CT for detecting nodal metastases were 51.1% (23/45), 99.8% (1,927/1,931), 85.2% (23/27), 98.9% (1,927/1,949) and 98.7% (1,950/1,976), respectively. The sensitivity for detecting metastatic lesions 4 mm or less in short-axis diameter was 12.5% (2/16), that for between 5 and 9 mm was 66.7% (16/24), and that for 10 mm or larger was 100.0% (5/5). The overall patient-based sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were 50% (6/12), 90.9% (30/33), 66.7% (6/9), 83.3% (30/36) and 80.0% (36/45), respectively. Integrated FDG-PET/contrast-enhanced CT is superior to conventional imaging, but only moderately sensitive in predicting lymph node metastasis preoperatively in patients with uterine cancer. (orig.)

    To evaluate the accuracy of integrated positron emission tomography and computed tomography (PET/CT) with iodinated contrast agent and {sup 18}F-fluorodeoxyglucose (FDG) in the diagnosis of suspected uterine cancer recurrence and to assess the impact of PET/CT findings on clinical management, compared with PET alone and enhanced CT alone. Of 103 women who had undergone treatment for histopathologically proven uterine cervical or endometrial cancer, 90 underwent FDG-PET/contrast-enhanced CT examination for suspected recurrence. PET-alone, CT-alone, and fused PET/CT images were interpreted by two radiologists by consensus for each investigation. Lesion status was determined on the basis of histopathology, radiological imaging and clinical follow-up for longer than 6 months. Differences among the three modalities were tested using the Cochran Q test, followed by multiple comparisons using the McNemar test with Bonferroni adjustment. Patient-based analysis showed that the sensitivity, specificity, and accuracy of PET alone were 79.5% (35/44), 73.9% (34/46), and 76.7% (69/90), respectively, whereas those of CT alone were 68.2% (30/44), 87.0% (40/46), and 77.8% (70/90), respectively, and those of PET/CT were 90.9% (40/44), 93.5% (43/46), and 92.2% (83/90), respectively. PET/CT findings resulted in a change of management in 38 of the 90 patients (42%) with an additional effect on patient management in 13 patients (14%) diagnosed by CT alone and 14 patients (16%) diagnosed by PET alone. FDG-PET/contrast-enhanced CT is a more accurate modality for assessing recurrence of uterine cancer, and led to more appropriate subsequent clinical management than that resulting from PET alone or enhanced CT alone.

    Using integrated PET/CT, we evaluated the prognostic relevance in uterine cervical cancer of preoperative pelvic lymph node (LN) [{sup 18}F]FDG uptake. Patients with FIGO stage IB to IIA uterine cervical cancer were imaged with FDG PET/CT before radical surgery. We used Cox proportional hazards regression to examine the relationship between recurrence and the FDG maximum standardized uptake value (SUV{sub max}) in the pelvic LN (SUV{sub LN}) on PET/CT. Clinical data, treatment modalities, and results in 130 eligible patients were reviewed. The median postsurgical follow-up was 34 months (range 6 to 109 months). Receiver operating characteristic analysis identified SUV{sub LN} 2.36 as the most significant cut-off value for predicting recurrence. SUV{sub LN} was correlated with SUV{sub tumour} (P = 0.002), primary tumour size (P = 0.004), and parametrial invasion (P = 0.013). Univariate analyses showed significant associations between recurrence and SUV{sub LN} (P = 0.001), SUV{sub tumour} (P = 0.007), pelvic LN metastasis (P = 0.002), parametrial invasion (P < 0.001), primary tumour size (P = 0.007), suspected LN metastasis on MRI (P = 0.024), and FIGO stage (P = 0.026). Multivariate analysis identified SUV{sub LN} (P = 0.013, hazard ratio, HR, 4.447, 95 % confidence interval, CI, 1.379 - 14.343) and parametrial invasion (P = 0.013, HR 6.728, 95 % CI 1.497 - 30.235) as independent risk factors for recurrence. Patients with SUV{sub LN} ≥2.36 and SUV{sub LN} <2.36 differed significantly in terms of recurrence (HR 15.20, P < 0.001). Preoperative pelvic LN FDG uptake showed a strong significant association with uterine cervical cancer recurrence. (orig.)

    There are two evidence based therapeutic options for locally advanced cervical cancer: Radiotherapy and concurrent chemotherapy (cisplatin alone or combined with other drugs) or radiation and hyperthermia, documented in randomised trials. The weight of evidence is less for the most advanced stages. Combination of all three options are currently tested in several centres with good clinical response and acceptable toxicity. Based on a pragmatic approach we propose to proceed with a trial selecting cisplatin concurrent with radiation therapy as the standard arm to be compared with the same regimen with the addition of hyperthermia once a week.

    The CALBC initiative aims to provide a large-scale biomedical text corpus that contains semantic annotations for named entities of different kinds. The generation of this corpus requires that the annotations from different automatic annotation systems be harmonized. In the first phase, the annotation systems from five participants (EMBL-EBI, EMC Rotterdam, NLM, JULIE Lab Jena, and Linguamatics) were gathered. All annotations were delivered in a common annotation format that included concept identifiers in the boundary assignments and that enabled comparison and alignment of the results. During the harmonization phase, the results produced from those different systems were integrated in a single harmonized corpus ("silver standard" corpus) by applying a voting scheme. We give an overview of the processed data and the principles of harmonization--formal boundary reconciliation and semantic matching of named entities. Finally, all submissions of the participants were evaluated against that silver standard corpus. We found that species and disease annotations are better standardized amongst the partners than the annotations of genes and proteins. The raw corpus is now available for additional named entity annotations. Parts of it will be made available later on for a public challenge. We expect that we can improve corpus building activities both in terms of the numbers of named entity classes being covered, as well as the size of the corpus in terms of annotated documents.

    Full Text Available Cervix neoplasm prevention is a practice of a nurse in the health care of women, which should be performed through qualified nursing appointment. Thus, the study aims at identifying the significance of nursing appointment on the prevention of cervix neoplasm held according to the precepts of humanistic nursing for women who have had it. It is a qualitative study that uses methodological referential convergent-search through assisted interviews. Then the perceptions of the patients regarding the experience of nursing consultation in humanistic perspective are described. Thus, the study sees the possibility of a new way to perform rigorous assistance in Humanistic Theory of Paterson and Zderad, which provides a dialogue with the nurses regarding the prevention of cervical cancer.

    Full Text Available Uterine sarcomas account for 3–7% of all uterine cancers. Because of their rarity, unknown etiology, and highly divergent genetic aberration, there is a lack of consensus on risk factors for occurrence and predictive poor outcomes as well as optimal therapeutic choices. Tumor types according to the World Health Organization classification include leiomyosarcoma, endometrial stroma sarcoma, and undifferentiated sarcoma. Staging is done using the 2014 Federation International Gynecology and Obstetrics and 2010 American Joint Committee on Cancer tumor, lymph node, and metastases systems. Tumor grade can be classified based on the French Federation of Cancer Centers Sarcoma Group system or the Broder’s system that incorporates tumor differentiation, mitotic count, and tumor necrosis. This review is a series of articles discussing uterine sarcoma, and this is Part I, which focuses on one of the subtypes of uterine sarcomas—uterine leiomyosarcoma. The clinical characteristics, diagnosis, outcome, and recent advances are summarized in this article.

    To evaluate the value of apparent diffusion coefficient (ADC) histogram analysis for predicting tumor recurrence in patients with uterine cervical cancer treated with chemoradiation therapy (CRT). Our institutional review board approved this retrospective study and waived informed consent from each patient. Forty-two patients (mean age, 56 ± 14 years) with biopsy-proven uterine cervical squamous cell carcinoma who underwent both pre-treatment pelvic magnetic resonance imaging with a 3.0 T magnetic resonance scanner and concurrent CRT were included. All patients were followed-up for more than 6 months (mean, 36.4 ± 11.9 months; range 9.0-52.8 months) after completion of CRT. Baseline ADC parameters (mean ADC, 25th percentile, 50th percentile, and 75th percentile ADC values) of tumors were calculated and compared between the recurrence and no recurrence groups. In the recurrence group, the mean ADC and 75th percentile ADC values of tumors were significantly higher than those of the no recurrence group (p = 0.043 and p = 0.008, respectively). In multivariate analysis, the 75th percentile ADC value of tumors was a significant predictor for tumor recurrence (p = 0.009; hazard ratio, 1.319). When the cut-off value of the 75th percentile ADC (0.936 x 10{sup -3} mm{sup 2}/sec) was used, the overall recurrence free survival rate above the cut-off value was significantly lower than that below the cut-off value (51.9% vs. 91.7%, p = 0.003, log-rank test). Pre-CRT ADC histogram analysis may serve as a biomarker for predicting tumor recurrence in patients with uterine cervical cancer treated with CRT.

    Full Text Available Background and Objective: The present study was done to analyze the immunoexpression of diagnostic markers (MIB-1: molecular immunology borstel and PCNA: proliferating cell nuclear antigen in grading cervical intraepithelial lesion (CIN and squamous cell carcinoma (SCC in cervix. Setting and Design: Total 150 cervical biopsies were divided into four groups respectively; Group I-Normal (n = 32, Group II- CIN (n = 60, Group III- SCC (n = 44, Group IV- CA cervix (n = 14 respectively. Materials and Methods: These biopsies were stained with monoclonal antibodies by streptavidin--biotin method. Mean labeling index was calculated and grading was performed using the I--III scoring system. Statistical Analysis: Findings were correlated with age and menopausal status. Statistical analysis was done by using student sample′t′ test and analysis of variance (ANOVA by SPSS 10 package. Results: MIB-1 immunostaining was positive in 112/150 (74.6% cases and PCNA in 118 /150 (78.6% cases. Labeling indices showed linear progression from normal to CIN to SCC to cancer lesion. Few cases of low-grade CIN lesion had high proliferative index. A significant positive correlation was found between age and PCNA and MIB-1 values (P < 0.05 when comparison was made for all the cases. Conclusion: These markers may be useful in identifying low-grade CIN lesion with high proliferative index. These cases should be kept for follow up studies so that proper intervention can be taken at an early stage. This method is simple and cost effective and can easily be done in formaline-fixed paraffin embedded tissues in a clinical laboratory for grading CIN and SCC lesions in cervix.

    Absorbed dose determination is an important step for risk assessment related to an exposure to ionizing radiation. However, physical dosimetry cannot be always performed, principally in the case of retrospective estimates. In this context, the use of bioindicators (biological effects) has been proposed, which defines the so-called biological dosimetry. In particular, scoring of unstable chromosomes aberrations (dicentrics, centric rings and fragments) of peripheral blood lymphocytes, while is the most reliable biological method for estimating individual exposure to ionizing radiation. In this work, blood samples from 5 patients, with cervical uterine cancer, were evaluated after partial-body radiotherapy with a source of {sup 69} Co. For this, conventional cytogenetic method was employed, based on Giemsa coloration and fluorescence in situ hybridization, in order to correlate the frequency of unstable chromosome aberrations of blood lymphocytes with absorbed dose, as a result of the radiotherapy. A good agreement was observed between the frequency of chromosome aberrations scored and the values of dose previously calculated by physical dosimetry during patient's radiotherapy. The results presented in this work point out the importance of concerning analyses of unstable chromosome aberrations as biological dosimeter in the investigation of partial-body exposure to ionizing radiation.

    Brachytherapy plays an important role in the treatment of patients with cervical carcinoma. Technical modalities have evolved during the last years and have benefited from imaging modalities development, specially MRI. Imaging modalities contribute to a better knowledge of tumoral extension and critical organs. Ultrasound during brachytherapy has led to the almost complete eradication of uterine perforation. In the future, a more systematic use of systems allowing optimization may induce a better dose distribution in the tumor as well as in the critical organs. Recent data provided information in favor of a better analysis in the relative role of dose-rate, total dose and treated volume and their influence on the local control and complication incidence. Concomitant radio-chemotherapy represents a standard in the treatment of patients with tumoral size exceeding 4 cm. Some questions still remain: is concomitant chemotherapy of benefit during brachytherapy? Is there any place for complementary surgery, specially in patients with complete response after external irradiation with concomitant chemotherapy and brachytherapy? In order to answer the former question, a phase III randomized trial is going to start, with the Federation Nationale des Centres de Lutte Contre le Cancer as a promoter. (authors)

    Treatment outcomes of patients with pelvic recurrence after hysterectomy alone for uterine cervical cancer who received salvage radiotherapy (RT) with or without concurrent chemotherapy were investigated. Salvage RT for recurrent cervical cancer confined to the pelvic cavity after hysterectomy alone was received by 33 patients. The median interval between initial hysterectomy and recurrence was 26 months. Whole-pelvic irradiation was delivered to median dose of 45 Gy, followed by a boost with a median dose of 16 Gy to the gross tumor volume. Cisplatin-based concurrent chemotherapy was administered to 29 patients. The median follow-up period was 53 months for surviving patients. Most patients (97.0%) completed salvage RT of ≥45 Gy. Complete response (CR) was achieved in 23 patients (69.7%). Pelvic sidewall involvement and evaluation with positron-emission tomography-computed tomography were significantly associated with CR. The 5-year progression-free survival (PFS), local control (LC), distant metastasis-free survival (DMFS), and overall survival (OS) rates were 62.7, 79.5, 72.5, and 60.1%, respectively. Initial International Federation of Gynecology and Obstetrics stage, pelvic sidewall involvement, and CR status were significant factors for PFS and OS rates in multivariate analysis. The incidence of severe acute and late toxicities (≥grade 3) was 12.1 and 3.0%, respectively. Aggressive salvage RT with or without concurrent chemotherapy for recurrent cervical cancer confined to the pelvic cavity was feasible, with promising treatment outcomes and acceptable toxicities. However, even more intensive novel treatment strategies should be investigated for patients with unfavorable prognostic factors. (orig.)

    The time course of human papillomavirus (HPV) DNA clearance was studied in patients with carcinoma of the cervix during follow-up after primary radical radiotherapy (RT). This study investigated the relationship between timing of HPV clearance and RT effectiveness. A total of 71 consecutive patients who were treated for cervical cancer with primary radical radiotherapy and high-dose rate intracavitary brachytherapy with or without chemotherapy were enrolled in the study. Samples for HPV DNA examination were taken before (1) treatment, (2) every brachytherapy, and (3) every follow-up examination. The times when HPV DNA was undetected were analyzed for association with recurrence-free survival. HPV DNA was not detected in 13 patients (18 %) before RT. Of the 58 patients with HPV DNA detected before treatment, HPV DNA was not detected in 34 % during treatment and in 66 % after the treatment. Within 6 months after RT, HPV DNA was detected in 0 % of all patients. The patients were followed up for a median period of 43 months (range 7-70 months). In all, 20 patients were found to develop recurrence. The 3-year cumulative disease-free survival (DFS) rate was 71 ± 5.4 % for all 71 patients. In multivariate analysis, DFS was significantly associated with HPV (detected vs. not detected) with a hazard ratio of 0.07 (95 % confidence interval 0.008-0.6, p = 0.009). In this study, patients in whom HPV was not detected had the worst prognosis. Six months after RT, HPV DNA was detected in 0 % of the patients. Patients in whom HPV DNA could not be detected before treatment need careful follow-up for recurrence and may be considered for additional, or alternative treatment. (orig.)

    Full Text Available Introduction Uterine torsion has been defined as a rotation of more than 45 degrees of the uterus around its long axis that occurs at the junction between the cervix and the corpus. The extent of the rotation is usually 180 degrees, although cases with torsion from 60 to 720 degrees have been reported. Aetiopathogenesis of this condition is still unclear. Establishing clinical diagnosis of this condition is difficult, but very important for reducing maternal and fetal morbidity and mortality. Clinical symptoms are either absent or nonspecific, and the diagnosis is usually made at laparotomy. Case outlineA 31-year old patient was admitted to the Institute of Gynecology and Obstetrics, Clinical Center of Serbia, Belgrade, as an emergency, seven days upon the established intrauterine fetal demise in the 40th gestation week. On uterine examination, the cervical length of 1.5 cm and dilatation of 3 cm were determined, as well as a palpable soft tissue formation, not resembling placenta praevia. Ultrasound examination confirmed fetal demise and exclusion of the presence of placenta praevia. The labor was completed by caesarean section. During surgery, uterine torsion of 180 degrees to the right was diagnosed. There was a stillborn male baby, and the cause of death was intrauterine asphyxia. A fibrosing and calcified accessory lobe 9x6x2.5 cm in size was observed on placental examination, which is a possible sign of initial gemellary pregnancy. Conclusion The clinical presentation of uterine torsion is variable and clinical examination and ultrasonographic scanning may be insufficient for diagnosis. The method of choice for establishing the diagnosis is magnetic resonance imaging. Once the diagnosis of uterine torsion in pregnancy is established, emergency laparotomy is indicated. Following caesarean delivery, it is necessary to surgically remove all the anatomical causes of torsion, and rotate the uterus back to its normal position. There are some

    To evaluate the operative and oncologic outcomes of an innovative technique for organ morcellation in patients scheduled for laparoscopic treatment of uterine malignancies. Endoscopy is currently considered the standard of care for the operative treatment of endometrial cancer; however, the use of minimal invasive surgery (MIS) is restricted in patients with a bulky uterus or narrow vagina. Conventional unprotected intraperitoneal uterine fragmentation is indeed contraindicated in these cases. Consequently, oncologically safe methods to render these patients eligible for MIS are urgently needed. Prospective study of women with histologically proven endometrial cancer in which uterus removal was a realistic concern owing to both organ size and proportionality. The patients underwent laparoscopic staging, including retroperitoneal lymphadenectomy, total hysterectomy, and bilateral salpingo-oophorectomy, followed by vaginal morcellation of the uterus inside a protective pouch (LapSac). In our series of 30 cases, we achieved successful completion in all patients, without conversion to laparotomy. No surgery-related casualty or intraoperative morbidity was observed. The mean organ size was 246 g (range, 148-420 g), and the average additional operative time related to vaginal morcellation was 16 minutes (range, 9-28 minutes). Proper histopathological staging according to 2009 FIGO staging guidelines could be performed in all specimens. Two patients (6%) presented with significant postoperative complications, 1 each with vesicovaginal fistula and vaginal vault dehiscence. Fourteen patients (46%) needed adjuvant therapy. After a median follow-up of 20 months (range, 6-38 months), the 12-month and 24-month overall survival was 100% and 73.4% (95% confidence interval, 51%-96%), respectively. Four patients with positive lymph nodes died of distant metastasis. No case of pelvic or local relapse was observed. Vaginal morcellation following oncologic principles is a feasible

    OBJECTIVE: Determine the risk of late gastrointestinal (GI) and bladder toxicities in women treated for Stage I uterine cancer with postoperative beam, implant, or combination radiation. METHODS: The Surveillance, Epidemiology, and End Results (SEER) tumor registry and Medicare claims were used to estimate the risk of developing late GI and bladder toxicities by type of radiation received. Bladder and GI diagnoses were identified 6-60 months after cancer diagnosis. Cox-proportional hazard models were used to estimate risk of any late GI or bladder toxicity due to type of radiation received. RESULTS: A total of 3,024 women with uterine cancer diagnosed from 1992-2005 were identified for analysis with a mean age of 73.9 (Standard Deviation (SD) ± 6.5). Bladder and GI toxicities occurred most frequently in the combination group, and least in the implant group. After controlling for demographic characteristics, tumor grade, diagnosis year, SEER region, comorbidities, prior GI and bladder diagnosis, and chemotherapy, women receiving implant radiation had a 21% absolute decrease in GI toxicities compared to women receiving combination radiation (Hazard Ratio (HR) 0.79, 95% confidence interval (CI) 0.68-0.92). No differences were observed between those receiving beam and combination in GI (HR 1.01 (0.89-1.14)) and bladder (HR 0.95 (0.80-1.11)) toxicities. CONCLUSIONS: Older women receiving combined radiation had the highest rates of GI and bladder toxicities, while women receiving implant radiation alone had the lowest rates. When selecting type of radiation for a patient, these toxicities should be considered. Counseling older women surviving cancer on late toxicities due to radiation must be a priority for physicians caring for them.

    Cervical cancer is strongly related to certain high-risk types of human papilloma virus infection. Breast cancer metastasis suppressor 1 (BRMS1) is a tumor suppressor gene, its expression being regulated by DNA promoter methylation in several types of cancers. This study aims to evaluate the methylation status of BRMS1 promoter in relation to high-risk types of human papilloma virus infection and the development of pre-cancerous lesions and describe the pattern of BRMS1 protein expression in normal, high-risk types of human papilloma virus-infected pre-cancerous and malignant cervical epithelium. We compared the methylation status of BRMS1 in cervical smears of 64 women with no infection by high-risk types of human papilloma virus to 70 women with proven high-risk types of human papilloma virus infection, using real-time methylation-specific polymerase chain reaction. The expression of BRMS1 protein was described by immunohistochemistry in biopsies from cervical cancer, pre-cancerous lesions, and normal cervices. Methylation of BRMS1 promoter was detected in 37.5% of women with no high-risk types of human papilloma virus infection and was less frequent in smears with high-risk types of human papilloma virus (11.4%) and in women with pathological histology (cervical intraepithelial neoplasia) (11.9%). Methylation was detected also in HeLa cervical cancer cells. Immunohistochemistry revealed nuclear BRMS1 protein staining in normal high-risk types of human papilloma virus-free cervix, in cervical intraepithelial neoplasias, and in malignant tissues, where staining was occasionally also cytoplasmic. In cancer, expression was stronger in the more differentiated cancer blasts. In conclusion, BRMS1 promoter methylation and aberrant protein expression seem to be related to high-risk types of human papilloma virus-induced carcinogenesis in uterine cervix and is worthy of further investigation.

    Full Text Available Background: While immunotherapy moved to the forefront of treatment of various cancers, it remains underexplored for uterine cancer. This might be due to the small patient population with advanced endometrial carcinoma and uterine sarcoma. Data about immunotherapeutic targets are scarce in endometrial carcinoma and lacking in uterine sarcoma. Methods: Expression of five tumor-associated antigens (TAA (BORIS, MUC1, hTERT, MAGE-A3 and Sp17 was validated in uterine tumor samples by immunohistochemistry (IHC and/or quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR. TAA immunogenicity was analyzed by determining spontaneous T cell responses towards overlapping peptide pools covering the whole TAA in patient blood. Results: At mRNA level, MAGE-A3 and Sp17 were overexpressed in a minority of patients and BORIS was moderately overexpressed (26% in endometrial carcinoma and 62% in uterine sarcoma. hTERT was overexpressed in the vast majority of tumors. On protein level, MUC1 was upregulated in primary, recurrent and metastatic EMCAR and in metastatic US tumors. hTERT protein was highly expressed in both normal and malignant tissue. Spontaneous TAA-specific T cell responses were detected in a minority of patients, except for hTERT to which T cell responses occurred more frequently. Conclusions: These data point to MUC1 and hTERT as most suitable targets based on expression levels and T cell immunogenicity for use in immunotherapeutic regimens.

    Full Text Available Problem statement: Speech corpus is one of the major components in corpus-based synthesis. The quality and coverage in speech corpus will affect the quality of synthesis speech sound. Approach: This study proposes a corpus design for Malay corpus-based speech synthesis system. This includes the study of design criteria in corpus-based speech synthesis, Malay corpus based database design and the concatenation engine in Malay corpus-based synthesis system. A set of 10 millions digital text corpuses for Malay language has been collected from Malay internet news. This text corpus had been analyzed using word frequency count to find out all high frequency words to be used for designing the sentences for speech corpus. Results: Altogether 381 sentences for speech corpus had been designed using 70% of high frequency words from 10 million text corpus. It consists of 16826 phoneme units and the total storage size is 37.6Mb. All the phone units are phonetically transcribed to preserve the phonetic context of its origin that will be used for phonetic context unit. This speech corpus had been labeled at phoneme level and used for variable length continuous phoneme based concatenation. Speech corpus is one of the major components in corpus-based synthesis. The quality and coverage in speech corpus will affect the quality of synthesized speech sound. Conclusion/Recommendation: This study has proposed a platform for designing speech corpus especially for Malay Text to Speech which can be further enhanced to support more coverage and higher naturalness of synthetic speech.

    The purpose of this study was to prospectively determine the diagnostic accuracy of PET/CT in the detection of recurrence in patients with treated uterine cancers. Twenty-five women, ranging in age from 37 to 79 years (mean 58.9 years), who underwent primary surgical treatment for either a cervical or an endometrial cancer met the inclusion criterion of the study, which was suspicion of recurrence based on results of routine follow-up procedures. PET/CT was performed after administration of {sup 18}F-fluorodeoxyglucose (FDG); two readers interpreted the images in consensus. Histopathological findings or correlation with results of subsequent clinical and imaging follow-up examinations served as the reference standard. Diagnostic accuracy of PET/CT was reported in terms of the proportion of correctly classified patients and lesion sites. Tumour recurrence was found at histopathological analysis or follow-up examinations after PET/CT in 14 (56%) of the 25 patients. Patient-based sensitivity, specificity, positive predictive value, negative predictive value and accuracy of PET/CT for detection of tumour recurrence were 92.9%, 100.0%, 100.0%, 91.7% and 96.0%, respectively. Lesion site-based sensitivity, specificity, positive predictive value, negative predictive value and accuracy of PET/CT were 94.7%, 99.5%, 94.7%, 99.5% and 99.0%, respectively. This preliminary study shows that PET/CT may be an accurate method for the evaluation of recurrence in patients who have been treated for uterine cancers and are undergoing follow-up. (orig.)

    Serum pepsinogen I and II are considered as indicators of changes in gastric morphology. Important publications from the last decades are reviewed with regard to the serum level of these biomarkers for the diagnosis of normal gastric mucosa, diffuse gastritis and its change to atrophic gastritis and intestinal metaplasia as well as gastric cancer. Due to the low sensitivity of serum biomarkers for diagnosis of gastric cancer, especially at its early stage and the poor prognosis of the tumor at the time of diagnosis, its prevention by eradication of H. pylori remains the mandatory strategy. On the other hand, the severity of regression and non-reversibility of precancerous lesions and intestinal metaplasia in gastric mucosa through eradication of H. pylori make it necessary to diagnose diffuse gastritis at its early stage. Increased serum pepsinogen II compared to normal serum pepsinogen I seems to indicate the presence of diffuse gastritis without precancerous lesions suitable for eradication of H. pylori infection, when it is serologically positive. A diagram illustrates the strategy of this therapeutic measure depending on the age of people and the level of serum biomarkers in areas with high gastric cancer prevalence.

    To evaluate low-dose non-enhanced CT (ldCT) and full-dose contrast-enhanced CT (ceCT) in integrated {sup 18}F-fluorodeoxyglucose (FDG) PET/CT studies for restaging of uterine cancer. A group of 100 women who had undergone treatment for uterine cervical (n=55) or endometrial cancer (n=45) underwent a conventional PET/CT scans with ldCT, and then a ceCT scan. Two observers retrospectively reviewed and interpreted the PET/ldCT and PET/ceCT images in consensus using a three-point grading scale (negative, equivocal, or positive) per patient and per lesion. Final diagnoses were obtained by histopathological examination, or clinical follow-up for at least 6 months. Patient-based analysis showed that the sensitivity, specificity and accuracy of PET/ceCT were 90% (27/30), 97% (68/70) and 95% (95/100), respectively, whereas those of PET/ldCT were 83% (25/30), 94% (66/70) and 91% (91/100), respectively. Sensitivity, specificity and accuracy did not significantly differ between two methods (McNemar test, p=0.48, p=0.48, and p=0.13, respectively). There were 52 sites of lesion recurrence: 12 pelvic lymph node (LN), 11 local recurrence, 8 peritoneum, 7 abdominal LN, 5 lung, 3 supraclavicular LN, 3 liver, 2 mediastinal LN, and 1 muscle and bone. The grading results for the 52 sites of recurrence were: negative 5, equivocal 0 and positive 47 for PET/ceCT, and negative 5, equivocal 4 and positive 43 for PET/ldCT, respectively. Four equivocal regions by PET/ldCT (local recurrence, pelvic LN metastasis, liver metastasis and muscle metastasis) were correctly interpreted as positive by PET/ceCT. PET/ceCT is an accurate imaging modality for the assessment of uterine cancer recurrence. Its use reduces the frequency of equivocal interpretations. (orig.)

    Full Text Available The development of acute myeloid leukaemia after low-dose radioiodine therapy and its presentation as a myeloid sarcoma of the uterine cervix are both rare events. We report a case of acute myeloid leukaemia revealed by a myeloid sarcoma of the uterine cervix in a 48-year-old woman, 17 months after receiving a total dose of 100 mCi 131I for papillary thyroid cancer. A strict hematological follow-up of patients treated with any dose of 131I is recommended to accurately detect any hematological complications which might have been underestimated. Unusual presentations, such as chloroma of the uterine cervix, may reveal myeloid malignancy and should be kept in mind.

    Limiting surgical morbidity while maintaining staging adequacy is a primary concern in obese patients with uterine malignancy. The goal of this study was to compare the surgical adequacy and postoperative morbidity of three surgical approaches to staging the disease of obese women with uterine cancer. The records of all patients with a body mass index (BMI) of >or=35 undergoing primary surgery for uterine corpus cancer at our institution from January 1993 to May 2006 were reviewed. Patients were assigned to three groups on the basis of planned surgical approach-standard laparotomy, laparoscopy, or laparotomy with panniculectomy. Standard statistical tests appropriate to group size were used to compare the three groups. In all, 206 patients with a BMI of >or=35 were grouped as follows: laparotomy, 154 patients; laparoscopy, 25 patients; and laparotomy with panniculectomy, 27 patients. Median BMI was 41 (range, 35-84). Regional lymph nodes were removed in 45% of the laparotomy patients, 40% of the laparoscopy patients, and 70% of the panniculectomy patients (P = .04). Compared with laparotomy, both laparoscopy and panniculectomy yielded higher median pelvic and total lymph node counts (P = .001). Operative time was shortest after standard laparotomy, and blood loss was greatest after panniculectomy. The incidence of all incisional complications was lower for panniculectomy (11%) and laparoscopy (8%) compared with standard laparotomy (35%) (P = .002). On multivariate analysis, a significantly lower risk of total incisional complications was seen for patients undergoing panniculectomy (risk ratio, .25; 95% confidence interval, .071-.88) and laparoscopy (risk ratio, .19; 95% confidence interval, .04-.94). Both laparoscopic staging and panniculectomy in a standardized fashion were associated with an improved lymph node count and a lower rate of incisional complications than laparotomy alone. Although definitive conclusions are limited by low patient numbers, the

    Evidences indicate that tumor development and progression towards a malignant phenotype depend not only on cancer cells themselves, but are also deeply influenced by tumor stroma reactivity. The present study uses mesenchymal stem cells from normal human uterine cervix (hUCESCs), isolated by the minimally invasive method of routine Pap cervical smear, to study their effect on the three main cell types in a tumor: cancer cells, fibroblasts and macrophages. Administration of hUCESCs-conditioned medium (CM) to a highly invasive breast cancer MDA-MB-231 cell line and to human breast tumors with high cell proliferation rates had the effect of reducing cell proliferation, modifying the cell cycle, inducing apoptosis, and decreasing invasion. In a xenograft mouse tumor model, hUCESCs-CM reduced tumor growth and increased overall survival. In cancer-associated fibroblasts, administration of hUCESCs-CM resulted in reduced cell proliferation, greater apoptosis and decreased invasion. In addition, hUCESCs-CM inhibited and reverted macrophage differentiation. The analysis of hUCESCs-CM (fresh and lyophilized) suggests that a complex paracrine signaling network could be implicated in the anti-tumor potential of hUCESCs. In light of their anti-tumor potential, the easy cell isolation method, and the fact that lyophilization of their CM conserves original properties make hUCESCs good candidates for experimental or clinical applications in anticancer therapy.

  17. Inappropriate cervical injection of radiotracer for sentinel node mapping in a uterine cervix cancer patient: importance of lymphoscintigraphy and blue dye injection

    Full Text Available Herein, we report a case of sentinel lymph node mapping in a uterine cervix cancer patient, referring to the nuclear medicine department of our institute. Lymphoscintigraphy images showed inappropriate intra‐cervical injection of radiotracer. Blue dye technique was applied for sentinel lymph node mapping, using intra‐cervical injection of methylene blue. Two blue/cold sentinel lymph nodes, with no pathological involvement, were intra‐operatively identified, and the patient was spared pelvic lymph node dissection. The present case underscores the importance of lymphoscintigraphy imaging in sentinel lymph node mapping and demonstrates the added value of blue dye injection in selected patients. It is suggested that preoperative lymphoscintigraphy imaging be considered as an integral part of sentinel lymph node mapping in surgical oncology. Detailed results of lymphoscintigraphy images should be provided for surgeons prior to surgery, and in case the sentinel lymph nodes are not visualized, use of blue dye for sentinel node mapping should be encouraged.

    Background Minimally invasive surgery (MIS) is associated with decreased complication rates, length of hospital stay, and cost compared with laparotomy. Robotic-assisted surgery—a method of laparoscopy—addresses many of the limitations of standard laparoscopic instrumentation, thus leading to increased rates of MIS. We sought to assess the impact of robotics on the rates and costs of surgical approaches in morbidly obese patients with uterine cancer. Methods Patients who underwent primary surgery at our institution for uterine cancer from 1993 to 2012 with a BMI ≥40 mg/m2 were identified. Surgical approaches were categorized as laparotomy (planned or converted), laparoscopic, robotic, or vaginal. We identified two time periods based on the evolving use of MIS at our institution: laparoscopic (1993–2007) and robotic (2008–2012). Direct costs were analyzed for cases performed from 2009 to 2012. Results We identified 426 eligible cases; 299 performed via laparotomy, 125 via MIS, and 2 via a vaginal approach. The rates of MIS for the laparoscopic and robotic time periods were 6 % and 57 %, respectively. The rate of MIS was 78 % in this morbidly obese cohort in 2012; 69 % were completed robotically. The median length of hospital stay was 5 days (range 2–37) for laparotomy cases and 1 day (range 0–7) for MIS cases (P < 0.001). The complication rate was 36 and 15 %, respectively (P < 0.001). The rate of wound-related complications was 27 and 6 %, respectively (P < 0.001). Laparotomy was associated with the highest cost. Conclusions The robotic platform provides significant health and cost benefits by increasing MIS rates in this patient population. PMID:26744108

    Full Text Available Uterine neoplasms composed of an admixture of smooth muscle and adipose tissue are rare and have been designated as lipoleiomyomas. The origin of this tumor is stil controversial and it has not been sufficiently studied. The aim of our study was to investigate the immunohistochemical phenotype of fat cells in uterine lipoleiomyomas so as to clarify their origin. Archived tissue samples of 10 uterine lipoleiomyomas were selected and analyzed immunohistochemically for vimentin, desmin, and HMB-45 expression. The patients ranged from 31 to 63 years of age (mean age 53.5±9.9. Seven tumors which affected the uterine corpus, showed intramural location; while two cases were subserosal, and one was in the cervix. All tumors were constituted by irregular bundles of smooth cells and mature large adipose cells. The amount of adipose component varied from 5 to 95% of the tumor mass. Cytological atypia and necrosis were not seen. Immunohistochemical investigations revealed obvious reactivity to vimentin and desmin in perivascular immature mesencyhmal cells and tumoral smooth muscle cells. Adipose cells in the tumors demonstrated uniform vimentin expression and inconsistent desmin immunoreactivity. All adipose cells were negative for HMB-45 antigen. However, HMB-45 antigen was weakly positive in spindle shaped tumor cells of two cases. In our study, the immunohistochemical findings suggest a complex histogenesis for these tumors, which may arise from perivascular immature mesencyhmal cells or direct transformation of smooth muscle cells into adipocytes by means of progressive intracellular storage of lipids.

    Involvement of the aryl hydrocarbon receptor (AHR) in carcinogenesis has been suggested in many studies. Upregulation of AHR has been reported in some cancer species, and an association between single-nucleotide polymorphisms (SNPs) of AHR and cancer risk or cancer development has also been reported. This evidence suggests the involvement of some specific SNPs in AHR transcriptional regulation in the process of carcinogenesis or cancer development, but there have been no studies to elucidate the mechanism involved. In this study, we identified the transcription factor Nuclear Factor 1-C (NF1C) as a candidate to regulate AHR transcription in a polymorphism-dependent manner. SNP rs10249788 was included in a consensus binding site for NF1C. Our results suggested that NF1C preferred the C allele to the T allele at rs10249788 for binding. Forced expression of NF1C suppressed the activity of the AHR promoter with C at rs10249788 stronger than that with T. Moreover, expression analysis of human uterine endometrial cancer (HEC) specimens showed greater upregulation of AHR and downregulation of NF1C than those of normal endometrium specimens. Sequence analysis showed HEC patients at advanced stages tended to possess T/T alleles more frequently than healthy women. We also demonstrated that NF1C suppressed proliferation, motility and invasion of HEC cells. This function was at least partially mediated by AHR. This study is the first to report that a polymorphism on the AHR regulatory region affected transcriptional regulation of the AHR gene in vitro. Because NF1C is a tumor suppressor, our new insights into AHR deregulation and its polymorphisms could reveal novel mechanisms of genetic susceptibility to cancer.

    Effect of ischemia of the uterine artery supplying with blood the main rhythmogenic zone (the ovarian region) of the uterine horn on parameters of activity both of this locus and of all subsequent pacemaker areas up to the uterine cervix was studied in non-pregnant rats. The most pronounced changes in characteristics of the activity (amplitude, frequency, and burst genesis duration) were revealed in the ovarian horn end. The uterine corpus and the horn cervical end were less affected by ischemia. Meanwhile, under these conditions, amplitude of the slow-wave oscillations rose more than 1.5 times. The obtained data allow us to conclude about the presence of a certain connection between the horn ovarian end and the uterine cervix. Morphological studies have revealed strong vascularization of the upper part of uterine horn.

    In this paper, we describe the construction of a semantically annotated corpus of clinical texts for use in the development and evaluation of systems for automatically extracting clinically significant information from the textual component of patient records. The paper details the sampling of textual material from a collection of 20,000 cancer patient records, the development of a semantic annotation scheme, the annotation methodology, the distribution of annotations in the final corpus, and the use of the corpus for development of an adaptive information extraction system. The resulting corpus is the most richly semantically annotated resource for clinical text processing built to date, whose value has been demonstrated through its use in developing an effective information extraction system. The detailed presentation of our corpus construction and annotation methodology will be of value to others seeking to build high-quality semantically annotated corpora in biomedical domains.

    We describe a recently developed corpus annotation scheme for evaluating parsers that avoids shortcomings of current methods. The scheme encodes grammatical relations between heads and dependents, and has been used to mark up a new public-domain corpus of naturally occurring English text. We show how the corpus can be used to evaluate the accuracy of a robust parser, and relate the corpus to extant resources.

    Multidrug resistance (MDR) mediated by P-glycoprotein (Pgp) remains one of the major obstacles to effective cancer chemotherapy. Several chemosensitizers have been used in vivo and in vitro to reverse MDR but have exhibited several unwanted side effects. Antipsychotics are often administered to treat psychiatric disorders such as delirium, anxiety and sleep disorders in cancer patients during chemotherapy. The present in vitro study, examined the effects of two common antipsychotic compounds, haloperidol and risperidone, and a natural compound such as theobromine on reversing MDR Pgp-mediated, to evaluate their potential use as chemosensitizing agents. The human doxorubicin (doxo) resistant uterine sarcoma cells (MES-SA/Dx5) that overexpress Pgp (100-fold), were treated with the antipsychotic alone (1, 10 and 20 μM) or in combination with different concentrations of doxo (2, 4 and 8 μM). The accumulation and cytotoxicity of doxo (MTT assay) and cellular GSH content (GSH assay) in comparison with verapamil, a well-known Pgp inhibitor, used as reference molecule were examined. It was found that the three compounds significantly enhanced the intracellular accumulation of doxo in resistant cancer cells, when compared with cells receiving doxo alone (p 30%) in resistant cells, when compared to untreated control cells (peffective Pgp inhibitor with the lowest toxicity.

    To evaluate the prognostic utility of volume-based parameters of fluorine-18 fludeoxyglucose positron emission tomography ((18)F-FDG PET) and apparent diffusion coefficient (ADC) histogram analysis for tumour response to therapy and event-free survival (EFS) in patients with uterine cervical cancer receiving chemoradiotherapy. The study included 21 patients diagnosed with locally advanced uterine cervical cancer who underwent pre-treatment MRI and (18)F-FDG PET and were treated with concurrent chemoradiotherapy. (18)F-FDG parameters: maximum and mean standardized uptake value; metabolic tumour volume (MTV); total lesion glycolysis (TLG); ADC parameters: maximum, mean and minimum values; percentile ADC values (10-90%); skewness and kurtosis of ADC were measured and compared between the responder and non-responder groups using a Wilcoxon rank-sum test. The Cox regression analysis and Kaplan-Meier survival curves were performed for EFS analysis. MTV and TLG of the primary tumour were significantly higher in the non-responder group than in the responder group (p = 0.04 and p = 0.01). Applying Cox regression multivariate analysis, MTV [hazard ratio (HR), 4.725; p = 0.036], TLG (HR, 4.725; p = 0.036) and 10-percentile ADC (HR, 5.207; p = 0.048) showed a statistically significant association with EFS. With the optimal cut-off value, the EFS rates above the cut-off value for MTV and TLG were significantly lower than that below the cut-off value (p = 0.002 and p = 0.002). Pre-treatment volume-based quantitative parameters of (18)F-FDG PET may have better potential than ADC histogram for predicting treatment response and EFS in patients with locally advanced cervical cancer. Advances in knowledge: In this study, pre-treatment volume-based quantitative parameters of (18)F-FDG PET had better potential than ADC histogram for predicting treatment response and survival in patients with locally advanced cervical cancer.

    Full Text Available Endometrial cancer is the most common gynecologic malignancy, and its incidence and associated mortality are increasing. Despite the immediate need to detect these cancers at an earlier stage, there is no effective screening methodology or protocol for endometrial cancer. The comprehensive, genomics-based analysis of endometrial cancer by The Cancer Genome Atlas (TCGA revealed many of the molecular defects that define this cancer. Based on these cancer genome results, and in a prospective study, we hypothesized that the use of ultra-deep, targeted gene sequencing could detect somatic mutations in uterine lavage fluid obtained from women undergoing hysteroscopy as a means of molecular screening and diagnosis.Uterine lavage and paired blood samples were collected and analyzed from 107 consecutive patients who were undergoing hysteroscopy and curettage for diagnostic evaluation from this single-institution study. The lavage fluid was separated into cellular and acellular fractions by centrifugation. Cellular and cell-free DNA (cfDNA were isolated from each lavage. Two targeted next-generation sequencing (NGS gene panels, one composed of 56 genes and the other of 12 genes, were used for ultra-deep sequencing. To rule out potential NGS-based errors, orthogonal mutation validation was performed using digital PCR and Sanger sequencing. Seven patients were diagnosed with endometrial cancer based on classic histopathologic analysis. Six of these patients had stage IA cancer, and one of these cancers was only detectable as a microscopic focus within a polyp. All seven patients were found to have significant cancer-associated gene mutations in both cell pellet and cfDNA fractions. In the four patients in whom adequate tumor sample was available, all tumor mutations above a specific allele fraction were present in the uterine lavage DNA samples.

    The first reported application of uterine artery embolization, in 1979, was to treat life-threatening hemorrhage after a failed hysterectomy. Since then, uterine artery embolization has been used very successfully to control acute or delayed post-partum hemorrhage, post-surgical hemorrhage and hemorrhage from ectopic pregnancy, to treat uterine arteriovenous malformations and as prophylaxis before high-risk surgery, such as cesarean delivery in women with placenta previa. In contrast to these proven but underutilized applications, uterine embolization for fibroids has, in a short time, achieved significant notice in the lay press and is being widely offered. Ravina and colleagues, first reported uterine fibroid shrinkage after embolization for the treatment of acute bleeding. Since then, his group has performed over 100 procedures with up to a 6-year follow-up. The cumulative clinical success rate for the treatment of abnormal uterine bleeding due to fibroids is reported to be approximately 85% and for treatment of pain or pressure symptoms, about 75%. Six-month follow-up sonography reveals an average reduction of fibroid size of approximately 40%. However, to date, no studies have compared patients who undergo embolization with a nontreatment cohort or with surgical intervention. (author)

    Diarylheptanoids from Curcuma comosa, of the Zingiberaceae family, exhibit diverse estrogenic activities. In this study we investigated the estrogenic activity of a major hydroxyl diarylheptanoid, 7-(3,4 -dihydroxyphenyl)-5-hydroxy-1-phenyl-(1E)-1-heptene (compound 092) isolated from C. comosa. The compound elicited different transcriptional activities of estrogen agonist at low concentrations (0.1-1 μM) and antagonist at high concentrations (10-50 μM) using luciferase reporter gene assay in HEK-293T cells. In human breast cancer (MCF-7) cells, compound 092 showed an anti-estrogenic activity by down-regulating ERα-signaling and suppressing estrogen-responsive genes, whereas it attenuated the uterotrophic effect of estrogen in immature ovariectomized rats. Of note, compound 092 promoted mouse pre-osteoblastic (MC3T3-E1) cell differentiation and the related bone markers, indicating its positive osteogenic effect. Our findings highlight a new, nonsteroidal, estrogen agonist/antagonist of catechol diarylheptanoid from C. comosa, which is scientific evidence supporting its potential as a dietary supplement to prevent bone loss with low risk of breast and uterine cancers in postmenopausal women.

The present investigation aimed to determine the activity of cancer procoagulant (CP) in subtypes of leiomyomas, including cellular leiomyomas, and to verify whether these activities correlate with immunoexpression of cell proliferation markers: the proliferating cell nuclear antigen (PCNA) and Ki-67. Preoperative peripheral venous blood and postoperative tissue material were obtained from 24 women operated on in a tertiary referral academic department. The activity of CP in serum was measured with the use of a coagulative method according to Gordon and Benson, and in tissue homogenates with the use of a spectrophotometric method according to Colucci et al. The control serum values were obtained from 20 healthy women without any gynecological disease, and the control solid tissue values from histologically confirmed postoperative normal reproductive tissues obtained from six patients. PCNA and Ki-67 expression were determined immunohistochemically using monoclonal antibodies. Both the tissue and serum activity for CP was considerably higher for common leiomyomas and cellular leiomyomas than for control tissues, but did not differ significantly between the leiomyoma subtypes. Intratumor CP activity significantly correlated with PCNA expression but not with Ki-67 expression. Cellular leiomyomas do not differ substantially in the serum and intratumor CP activity from common leiomyomas. There is a relationship of intratumor CP activity with PCNA expression, a finding which requires further investigation.

    Full Text Available Abstract Background Human papillomavirus (HPV infection plays an etiological role in the development of cervical dysplasia and cancer. Amplification of human telomerase gene (hTERC and over expression of telomerase were found to be associated with cervical tumorigenesis. This study was performed to analyze genomic amplification of hTERC gene, telomerase activity in association with HPV infection in different stages of cervical intraepithelial neoplasia (CIN and cervical cancer. We were studying the role of hTERC in the progression of uterine cervical dysplasia to invasive cancer, and proposed an adjunct method for cervical cancer screening. Methods Exfoliated cervical cells were collected from 114 patients with non neoplastic lesion (NNL, n=27, cervical intraepithelial neoplasia (CIN1, n=26, CIN2, n=16, CIN3, n=24 and cervical carcinoma (CA, n=21, and analyzed for amplification of hTERC with two-color fluorescence in situ hybridization (FISH probe and HPV-DNA with Hybrid Capture 2. From these patients, 53 were taken biopsy to analyze telomerase activity by telomeric repeat amplification protocol (TRAP and expression of human telomerase reverse transcriptase (hTERT, with immunohistochemistry (IHC. All biopsies were clinically confirmed by phathologists. Results Amplification of hTERC was significantly associated with the histologic diagnoses (p Conclusions hTERC ampliffication can be detected with FISH technique on exfoliated cervical cells. Amplification of hTERC and HPV infection are associated with more progressive CIN3 and CA. The testing of hTERC amplification might be a supplementary to cytology screening and HPV test, especially high-risk patients.

    Full Text Available Uterine sarcomas are rare tumors accounting for 3,4% of all uterine cancers. Even after radical hysterectomy, most patients relapse or present with distant metastases. The very limited clinical benefit of adjuvant cytotoxic treatments is reflected by high mortality rates, emphasizing the need for new treatment strategies. This review summarizes rising potential targets in four distinct subtypes of uterine sarcomas: leiomyosarcoma, low-grade and high-grade endometrial stromal sarcoma, and undifferentiated uterine sarcoma. Based on clinical reports, promising approaches for uterine leiomyosarcoma patients include inhibition of VEGF and mTOR signaling, preferably in combination with other targeted or cytotoxic compounds. Currently, the only targeted therapy approved in leiomyosarcoma patients is pazopanib, a multitargeted inhibitor blocking VEGFR, PDGFR, FGFR, and c-KIT. Additionally, preclinical evidence suggests effect of the inhibition of histone deacetylases, tyrosine kinase receptors, and the mitotic checkpoint protein aurora kinase A. In low-grade endometrial stromal sarcomas, antihormonal therapies including aromatase inhibitors and progestins have proven activity. Other potential targets are PDGFR, VEGFR, and histone deacetylases. In high-grade ESS that carry the YWHAE/FAM22A/B fusion gene, the generated 14-3-3 oncoprotein is a putative target, next to c-KIT and the Wnt pathway. The observation of heterogeneity within uterine sarcoma subtypes warrants a personalized treatment approach.

    OBJECTIVE To investigate the short-term and long-term therapeutic efficacy of preoperative intra-arterial infusion chemo-embolization on stage IB2-IIB Uterine cervix cancer (UCC). METHODS A total of 143 patients with Stage IB2-lIB UCC were divided into a clinical trial group and a control group. The patients in the clinical trial group (n/=86) were treated with a combined therapy, i.e. preoperative intra-arterial infusion chemo-embolization, surgical therapy and postoperative radiotherapy, and those in the control group(n=57)were given surgical therapy and post-operative radiotherapy. The adverse effects, changes in local lesion and pathological examinations of the cancer, and the state during the surgery were observed after the intra-arterial infusion chemo-embolization. The survival rate and recurrence rate between the two groups were compared. RESUITS The total effective rate of the intra- arterial infusion chemo-embolization on Stage IB2-IIB UCC was 93.02%. The treatment could reduce tumor size, bring about retro-conversions of the clinical stage of the tumors and pathological grade of the cancer cells, and decrease the quantity, of intra-operative blood loss as well as the operating time. It could significantly improve the 5-year survival rate (P<0.05), and reduce the 2 and 5-yeartumor recurrence rates(P<0.05). Moreover, its side effects were little. CONCLUSIOAN Preoperative intra-arterial infusion chemo-embolization can create conditions for radical operation, lower the postoperative recurrence rate, and improve the prognosis in the patients with UCC. It is an effctive therapy in treating UCC.

    We investigated daily needle applicator displacement during high-dose-rate interstitial brachytherapy. Ten patients with previously untreated uterine cervical cancer received 30Gy in five fractions during 3 days of high-dose-rate interstitial brachytherapy combined with external beam radiotherapy using our unique ambulatory technique. To analyze displacement, we obtained daily computed tomography (CT) images for 147 flexible needle applicators at 21 and 45h after implantation. The distance was defined as the length between the center of gravity of titanium markers and the needle applicator tips along the daily CT axis. We adapted dwell positions of the treatment source to cover clinical target volume with a 15-mm cranial margin. The median displacement was 1mm (range, -6 to 12mm) at 21h and 2mm (range, -9 to 14mm) at 45h, respectively. Statistically significant caudal displacement was observed only between the displacement at 0 and 21h (pBrachytherapy Society. Published by Elsevier Inc. All rights reserved.

    Peritumoral desmoplastic stromal reaction (DSR) with myofibroblastic phenotype may be of prognostic impact in uterine cervical carcinoma. The present study evaluates the immunostaining (CD34 and smooth muscle actin; SMA) of 97 squamous cell cancers. Staining was scored as low/negative (50%) and DSR as negative/weak and moderate/strong. The staining results were correlated to patient survival. Of the cases, 78.3% showed a decreased of CD34 (SMA staining with more than 50% SMA positive stromal cells. Tumors representing moderate/strong DSR showed a significant decreased CD34 (P=.001) and an increased but not statistically significant SMA staining (P=0.345). Cases with low CD34 and high SMA staining showed reduced 5-year overall survival when compared to cases with high CD34 and low SMA positivity (59.9 vs 81.0%; P=0.025 and 64.6 vs 81.1%; P=0.243). Peritumoral stromal response in cervical carcinoma is immunohistochemically characterized by CD34(low)/SMA(high) and associated reduced overall survival. © 2013.

    Objective: to evaluate, by means of magnetic resonance imaging, the standardized field borders in radiotherapy for malignant neoplasm of uterine cervix, and to determine the role of this method in the reduction of possible planning errors related to the conventional technique. Materials and methods: magnetic resonance imaging studies for planning of treatment of 51 patients with uterine cervix cancer were retrospectively analyzed. The parameters assessed were the anterior and posterior field borders on sagittal section. Results: The anterior field border was inappropriate in 20 (39.2%) patients and geographic miss was observed in 37.3% of cases in the posterior border. The inappropriateness of both field borders did not correlate with clinical parameters such as patients' age, tumor staging, histological type and degree. Conclusion: the evaluation of standardized field borders with the use of magnetic resonance imaging has demonstrated high indices of inappropriateness of the lateral field borders, as well as the relevant role of magnetic resonance imaging in the radiotherapy planning for patients with uterine cervix cancer with a view to reduce the occurrence of geographic miss of the target volume.

    In this article, we propose an automatic process to build multi-lingual lexico-semantic resources. The goal of these resources is to browse semantically textual information contained in texts of different languages. This method uses a mathematical model called Atlas s\\'emantiques in order to represent the different senses of each word. It uses the linguistic relations between words to create graphs that are projected into a semantic space. These projections constitute semantic maps that denote the sense trends of each given word. This model is fed with syntactic relations between words extracted from a corpus. Therefore, the lexico-semantic resource produced describes all the words and all their meanings observed in the corpus. The sense trends are expressed by syntactic contexts, typical for a given meaning. The link between each sense trend and the utterances used to build the sense trend are also stored in an index. Thus all the instances of a word in a particular sense are linked and can be browsed easily...

    Full Text Available Over recent years, the use of corpora in stylistic analysis has grown in popularity. However, questions still remain over the remit of corpus stylistics, its distinction from corpus linguistics generally and its capacity to explain complex stylistic effects. This article argues in favour of an integrated corpus stylistics; that is, an approach to corpus stylistics that integrates it with other stylistic methods and analytical frameworks. I suggest that this approach is needed for two main reasons: (i it is analytically necessary in order to fully explain stylistic effects in texts, and (ii integrating corpus methods with other stylistic tools is what will distinguish corpus stylistics from corpus linguistics. My argument is supported by reference to examples from Mark Haddon’s no vel The Curious Incident of the Dog in the Night-time and the HBO TV series Deadwood. Both these examples rely for their explanation on a combination of corpus stylistic analytical techniques and other stylistic methods of analysis.

    The originator and founder of hermetism was the mythical Hermes Trismegistos, a deity of the syncretic Hellenistic religion that came into being through the identification of the Greek god Hermes with the Egyptian god Thot. In later Hellenistsic times various hermetic writers considered Hermes Trismegistos to have been a historical personage, a king, prophet and philosopher (physician), as well as author of many widely disseminated writings that made up the so-called Corpus Hermeticum (eighteen separate treatises from the 2nd-4th centuries AD) and the so-called Emerald Table (Tabula Smaragdina). The Corpus Hermeticum is a collection of treatises of a philosophical, religious, theological as well as theosophical nature. The collection played an important role in the development of the philosophy of alchemy and hermetism, and formed the basis for an alchemist philosophy of nature. There are currently two views among scholars on the origins of hermetism. According to one, hermetism derived directly from Egypt, while according to the other it orginated in Greece. In the years 1945-46 a number of hermetic texts forming part of the now famous gnostic "library" were discovered in Nag-Hammadi (Chenosboskion) in Upper Egypt. The Coptic texts from Nag-Hammadi date from the middle of the 4th century AD, and according to experts are translations from the Greek. Some authors (R. Reitzenstein and T. Zieliński) have suggested that along with the appearance in Egypt of the Hermetic Books, attributed to Hermes Trismegistos, there also appeared a new god in Egypt, Poimandres, and a new religion was established, hermetism, which competed for influence with Christianity. The present article discusses the main of the hermetic treatises, including Poimandres, which contains an account of the creation of the world. The article also discusses the reasons for the decline of hermetism as a religion and stresses that in spite of this decline the doctrine managed to survive in the form of

    Primitive neuroectodermal tumors are fairly rare in uterus. A case of uterine body primitive neuroectodermal tumor in a 32-year-old Iranian woman is presented. The patient was admitted with abdominal pain and fever and underwent emergency exploratory surgery with total abdominal hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymph node dissection. Posterior wall of the uterus was necrotic and ruptured and a huge tumor disrupted the uterine body. The tumor was strongly positive for CD99, NSE, and chromogranin; No reaction was seen for CD10, CD45 and myogenin. To the best of our knowledge, this is the first report of an uterine body primitive neuroectodermal tumor and the second report of uterine primitive neuroectodermal tumor from Iran.

  6. Universum Inference and Corpus Homogeneity

    Science.gov (United States)

    Vogel, Carl; Lynch, Gerard; Janssen, Jerom

    Universum Inference is re-interpreted for assessment of corpus homogeneity in computational stylometry. Recent stylometric research quantifies strength of characterization within dramatic works by assessing the homogeneity of corpora associated with dramatic personas. A methodological advance is suggested to mitigate the potential for the assessment of homogeneity to be achieved by chance. Baseline comparison analysis is constructed for contributions to debates by nonfictional participants: the corpus analyzed consists of transcripts of US Presidential and Vice-Presidential debates from the 2000 election cycle. The corpus is also analyzed in translation to Italian, Spanish and Portuguese. Adding randomized categories makes assessments of homogeneity more conservative.

    The aim of this study was to compare the dosimetric parameters of whole-pelvic radiotherapy (WPRT) for cervical cancer among plans involving 3D conformal radiotherapy (3D-CRT), intensity-modulated radiotherapy (IMRT), or spot-scanning proton therapy (SSPT). The dose distributions of 3D-CRT-, IMRT-, and SSPT-based WPRT plans were compared in 10 patients with cervical cancer. All of the patients were treated with a prescribed dose of 50.4 Gy in 1.8-Gy daily fractions, and all of the plans involved the same planning target volume (PTV) constrictions. A 3D-CRT plan involving a four-field box, an IMRT plan involving seven coplanar fields, and an SSPT plan involving four fields were created. The median PTV D95% did not differ between the 3D-CRT, IMRT and SSPT plans. The median conformity index 95% and homogeneity index of the IMRT and SSPT were better than those of the 3D-CRT. The homogeneity index of the SSPT was better than that of the IMRT. SSPT resulted in lower median V20 values for the bladder wall, small intestine, colon, bilateral femoral heads, skin, and pelvic bone than IMRT. Comparing the Dmean values, SSPT spared the small intestine, colon, bilateral femoral heads, skin and pelvic bone to a greater extent than the other modalities. SSPT can reduce the irradiated volume of the organs at risk compared with 3D-CRT and IMRT, while maintaining excellent PTV coverage. Further investigations of SSPT are warranted to assess its role in the treatment of cervical cancer. PMID:27380800

    A polymorphism at codon 72 in the p53 gen has been reported as a potential risk factor to cervical cancer (CC) because human papillomavirus (HPV) is more effective at degrading p53 Arg-72 than p53 Pro-72, making individuals homozygous for p53 Arg-72 seven times more likely to develop HPV-associated CC. As In Mexico the CC is a health public problem, we designed this study to determinate whether the p53 codon 72 polymorphism represent a risk factor to CC in our population. A case-controls study was performed. DNA was obtained from paraffin-embedded cervical fixed tissue samples. Analysis of the p53 genotype at position 72 was performed by polymerase chain reaction using specific primers and Accll digestion. Among cases with CC the proportions of the p53 genotypes at codon 72 were 0.05 to proline homozygous, 0.5 to heterozygous, and 0.45 to arginine-homozygous. In controls the proportions were 0.08, 0.62, and 0.31. X2 test showed no significant difference In the proportions. We conclude than In our population, as other worldwide countries, the homozygous for arginine at codon 72 of the p53 gene is not a risk factor to cervical cancer.

    In codon 72 of the p53 antioncogene there are two alleles, arginine and proline; the arg/arg genotype has recently been identified as a risk factor for developing of cervicouterine cancer (CuCa) associated to human papillomavirus (HVP) infection. The aim of this work was to determine in a sample of women the frequency of proline-arginine alleles and genotypes of p53 codon 72. The study was conducted in a sample of inpatient women at the hospital. p53 codon 72 alleles were determined in genomic ADN by amplification of specific sequences by chi 2 test. From 102 analyzed samples, p53-arginine allele corresponded to 67.64% and p53-proline allele corresponded to 32.36%; 47 women (46.10%) were arg/arg homocygotes, 11 women (10.77%) were pro/pro homocygotes, 44 women (43.13%) were arg/pro heterocigotes; the genotype distribution was within the Hardy-Weinberg equilibrium. The detection of a high percentage of arginine homocygotes suggests that this genotype, considered as a risk factor for cancer associated to oncogenic HPV, has a high prevalence in the north of Mexico. The determination of this kind of polymorphisms is important as preventive action with regard to identification of risk factors for CaCu associated to HPV infection.

    Full Text Available Abstract Backgroud Bone mineral density (BMD is a marker of long-term estrogen exposure. BMD measurement has been used in this context to investigate the association of estrogen with breast cancer risk in three cohorts. In order to assess further BMD as a predictor of estrogen related cancer risk, the association of BMD with colorectal and corpus uteri cancer was investigated in the NHANES I Epidemiologic Followup Study (NHEFS cohort along with breast cancer and prostate cancer. Methods Participants were members of the NHEFS cohort who had BMD measurement in 1974–1975. Age, race, and BMI adjusted rate ratios and 95% confidence intervals were calculated for incidence of cancers of the corpus uterus, breast, colorectum, prostate, and of osteoporosis and hip fracture related to baseline BMD. Results Data were available for 6046 individuals. One hundred cases of breast cancer, 94 prostate cancers, 115 colorectal cancers, 29 uterine cancers, 110 cases of hip fracture and 103 cases of osteoporosis were reported between 1974 and 1993. Hip fracture and osteoporosis were both significantly inversely associated with BMD. Uterine cancer was positively associated (p = 0.005, test for linear trend and colorectal cancer negatively associated (p = 0.03 with BMD. No association was found between elevated BMD and incidence of breast cancer (p = 0.74 or prostate cancer (p = 0.37 in the overall cohort, although a weak association was seen between BMD and subsequent breast cancer incidence when BMD was measured in post-menopausal women (p = 0.04. Conclusion The findings related to cancers of the uterus and colorectum as well as the weak association of BMD with breast cancer strengthen the use of BMD as a marker of estrogen exposure and cancer risk.

    The best dose-fractionation regimen of the definitive radiotherapy for cervix cancer remains to be clearly determined. It seems to be partially attributed to the complexity of the affecting factors and the lack of detailed information on external and intra-cavitary fractionation. To find optimal practice guidelines, our experiences of the combination of external beam radiotherapy (EBRT) and high-dose-rate intracavitary brachytherapy (HDR-ICBT) were reviewed with detailed information of the various treatment parameters obtained from a large cohort of women treated homogeneously at a single institute. The subjects were 743 cervical cancer patients (Stage IB 198, IIA 77, IIB 364, IIIA 7, IIIB 89 and IVA 8) treated by radiotherapy alone, between 1990 and 1996. A total external beam radiotherapy (EBRT) dose of 23.4 {approx} 59.4 Gy (Median 45.0) was delivered to the whole pelvis. High-dose-rate intracavitary brachytherapy (HDR-ICBT) was also performed using various fractionation schemes. A Midline block (MLB) was initiated after the delivery of 14.4{approx} 43.2 Gy (Median 36.0) of EBRT in 495 patients, while in the other 248 patients EBRT could not be used due to slow tumor regression or the huge initial bulk of tumor. The point A, actual bladder and rectal doses were individually assessed in all patients. The biologically effective dose (BED) to the tumor ({alpha} / {beta} = 10) and late-responding tissues ({alpha} /{beta} = 3) for both EBRT and HDR-ICBT were calculated. The total BED values to point A, the actual bladder and rectal reference points were the summation of the EBRT and HDR-ICBT. In addition to all the details on dose-fractionation, the other factors (i.e. the overall treatment time, physicians preference) that can affect the schedule of the definitive radiotherapy were also thoroughly analyzed. The association between MD-BED Gy{sub 3} and the risk of complication was assessed using serial multiple logistic regressions models. The associations between R

    Full Text Available The paper discusses several key concepts related to the development of corpora and reconsiders them in light of recent developments in NLP. On the basis of an overview of present-day corpora, we conclude that the dominant practices of corpus design do not utilise adequately the technologies and, as a result, fail to meet the demands of corpus linguistics, computational lexicology and computational linguistics alike.We proceed to lay out a data-driven approach to corpus design, which integrates the best practices of traditional corpus linguistics with the potential of the latest technologies allowing fast collection, automatic metadata description and annotation of large amounts of data. Thus, the gist of the approach we propose is that corpus design should be centred on amassing large amounts of mono- and multilingual texts and on providing them with a detailed metadata description and high-quality multi-level annotation.We go on to illustrate this concept with a description of the compilation, structuring, documentation, and annotation of the Bulgarian National Corpus (BulNC. At present it consists of a Bulgarian part of 979.6 million words, constituting the corpus kernel, and 33 Bulgarian-X language corpora, totalling 972.3 million words, 1.95 billion words altogether. The BulNC is supplied with a comprehensive metadata description, which allows us to organise the texts according to different principles. The Bulgarian part of the BulNC is automatically processed (tokenised and sentence split and  annotated at several levels: morphosyntactic tagging, lemmatisation, word-sense annotation, annotation of noun phrases and named entities. Some levels of annotation are also applied to the Bulgarian-English parallel corpus with the prospect of expanding multilingual annotation both in terms of linguistic levels and the number of languages for which it is available. We conclude with a brief evaluation of the quality of the corpus and an outline of

    Objective: To evaluate an alternative brachytherapy technique for uterine cervix cancer involving the distal vagina, without increasing the risk of toxicity. Materials And Methods: Theoretical study comparing three different high-dose rate intracavitary brachytherapy applicators: intrauterine tandem and vaginal cylinder (TC); tandem/ring applicator combined with vaginal cylinder (TR+C); and a virtual applicator combining both the tandem/ring and vaginal cylinder in a single device (TRC). Prescribed doses were 7 Gy at point A, and 5 Gy on the surface or at a 5 mm depth of the vaginal mucosa. Doses delivered to the rectum, bladder and sigmoid colon were kept below the tolerance limits. Volumes covered by the isodoses, respectively, 50% (V50), 100% (V100), 150% (V150) and 200% (V200) were compared. Results: Both the combined TR+C and TRC presented a better dose distribution as compared with the TC applicator. The TR+C dose distribution was similar to the TRC dose, with V150 and V200 being about 50% higher for TR+C (within the cylinder). Conclusion: Combined TR+C in a two-time single application may represent an alternative therapy technique for patients affected by uterine cervix cancer involving the distal vagina. (author)

    To explore the dosimetric advantage of target volume and surrounding normal tissue by using interstitial (IS) brachytherapy (BT) based on three-dimensional CT in locally advanced cervical cancer, as a simple and effective clinical treatment approach. Fifty-two patients with poor tumor response to external beam radiotherapy and a residual tumor >5 cm at the time of the first BT were included. IS BT was performed using a "hybrid" applicator combining uterine tandem and free metal needles based on three-dimensional CT. The high-risk clinical target volume (HR-CTV), intermediate-risk clinical target volume, and organs at risk were contoured. The total dose, including external beam radiotherapy (45 Gy in 25 fractions) and high-dose-rate BT (30 Gy in 5 fractions), was biologically normalized to conventional 2-Gy fractions. D90 and D100 for HR-CTV and intermediate-risk clinical target volume and D2cc for the bladder, rectum, and sigmoid were analyzed. The mean D90 value for HR-CTV was 88.4 ± 3.5 Gy. Totally, 88.5% of the patients received D90 for HR-CTV ≥87 Gy. The D2cc for the bladder, rectum, and sigmoid were 81.1 ± 5.6, 65.7 ± 5.1, and 63.1 ± 5.4 Gy, respectively. The mean number of needles was 6.9 ± 1.3 for each application. IS BT was associated with minor complications. IS BT using the "hybrid" applicator provides a dosimetric advantage for target volume and organs at risk in large-volume (>5 cm) tumors and is, thereby, clinically feasible. However, the long-term curative effect and possible toxicity need further clinical observation. Copyright © 2016 American Brachytherapy Society. Published by Elsevier Inc. All rights reserved.

    Full Text Available Uterine mesenchymal tumors are a heterogeneous group of neoplasms that can frequently be diagnostically challenging. Differentiation between the benign and malignant counterparts of mesenchymal tumors is significant due to differences in clinical outcome, and the role of the surgical pathologist in making this distinction (especially in the difficult cases cannot be underestimated. Although immunohistochemical stains are supportive toward establishing a final diagnosis, the morphologic features trump all the other ancillary techniques for this group of neoplasms. This review therefore emphasizes the key morphologic features required to diagnose and distinguish uterine mesenchymal tumors from their mimics, with a brief description of the relevant immunohistochemical features.

  6. DEVELOPING SOFTWARE FOR CORPUS RESEARCH

    Oliver Mason

    2008-06-01

    Full Text Available Despite the central role of the computer in corpus research, programming is generally not seen as a core skill within corpus linguistics. As a consequence, limitations in software for text and corpus analysis slow down the progress of research while analysts often have to rely on third party software or even manual data analysis if no suitable software is available. Apart from software itself, data formats are also of great importance for text processing. But again, many practitioners are not very aware of the options available to them, and thus idiosyncratic text formats often make sharing of resources difficult if not impossible. This article discusses some issues relating to both data and processing which should aid researchers to become more aware of the choices available to them when it comes to using computers in linguistic research. It also describes an easy way towards automating some common text processing tasks that can easily be acquired without knowledge of actual computer programming.

    Upregulation of lncRNA H19 expression is associated with an unfavorable prognosis in some cancers. However, the prognostic value of H19 in female-specific cancers has remained uncharacterized. In this study, the prognostic power of high H19 expression in female cancer patients from the TCGA datasets was analyzed using Kaplan-Meier survival curves and Cox's proportional hazard modeling. In addition, in a meta-analysis of non-female cancer patients from TCGA datasets and 12 independent studies, hazard ratios (HRs) with 95% confidence interval (CI) for overall survival (OS) and disease-free survival (DFS)/relapse-free survival (RFS)/metastasis-free survival (MFS)/progression-free survival (PFS) were pooled to assess the prognostic value of high H19 expression. Kaplan-Meier analysis revealed that patients with uterine corpus cancer and higher H19 expression had a shorter OS (HR=2.710, p<0.05), while females with cervical cancer and increased H19 expression had a shorter RFS (HR=2.261, p<0.05). Multivariate Cox regression analysis showed that high H19 expression could independently predict a poorer prognosis in cervical cancer patients (HR=4.099, p<0.05). In the meta-analysis, patients with high H19 expression showed a poorer outcome in non-female cancer (p<0.05). These results suggest that high lncRNA H19 expression is predictive of an unfavorable prognosis in two female cancers (uterine corpus endometrioid cancer and cervical cancer) as well as in non-female cancer patients.

    The aim of the present study was to evaluate the effect of the embryo transfer (ET) maneuvers on plasma progesterone concentrations in recipient Lama glama females and the relationship between the site the embryo was transferred to and corpus luteum (CL) localization. Experiment I (effect of transcervical threading): adult non-pregnant, non-lactating llama females were randomly assigned into two groups: control group (without cervical threading, n=10) and group A (with cervical threading, n=10). In both groups, CL activity was evaluated through measurement of progesterone plasma concentrations. In group A, on Day 6 after inducing ovulation with buserelin, the cervix was threaded to evaluate the effect of the maneuver on CL viability. No significant differences were observed in mean progesterone concentrations between groups (P>0.05). Experiment II (effect of depositing PBS): females (n=66) were randomly assigned into six groups (n=10 per group and control group: n=6) to evaluate the effect of depositing PBS in different sites in the uterus in relation to the localization of the CL: group 'Left-Ipsilateral': transcervical placing of PBS in the left uterine horn (CL in left ovary); group 'Left-Contralateral': transcervical placing of PBS in the left uterine horn (CL in right ovary); group 'Right-Ipsilateral': transcervical placing of PBS in the right uterine horn (CL in right ovary); group 'Body-Left': transcervical placing of PBS in the uterine body (CL in left ovary); group 'Body-Right': transcervical placing of PBS in the uterine body (CL in right ovary) and control group. Corpus luteum activity was evaluated in all groups by measuring plasma progesterone concentrations. On Day 6 post-buserelin, the corresponding maneuver was carried out according to the group. No significant differences were found for the mean plasma progesterone concentrations between groups (P>0.05). Experiment III (effect of ET on CL viability): females (n=22) were used as embryo donors and 50

    Objective. To characterize the radiologic features of postradiation sarcomas arising in the pelvic bones following treatment for uterine cervical carcinoma. Design and patients. Five patients who developed postradiation sarcomas in the pelvic bones following radiation therapy for carcinoma of the uterine cervix within the irradiated field were evaluated. Pelvic radiographs, computed tomography (CT) and magnetic resonance (MR) imaging were undertaken in all patients. Histologic confirmation of the tumor type was obtained. Results. Three patients whose tumors were characterized as an osteosarcoma, an angiosarcoma and a malignant fibrous histiocytoma (MFH) showed a large round or oval mass mainly in the sacroiliac joint which extended into the posterior gluteal soft tissues. In a fourth patient an osteosarcoma developed in the central ilium extending widely into the soft tissues both anteriorly and posteriorly, with calcified areas within the extraosseous mass. The fifth patient had a MFH which showed osteolytic destruction of the cortex of the acetabulum, and minimal soft tissue extension. There were no specific features or signal intensity changes on MR imaging to differentiate these cases from primary sarcomas. Conclusion. Postradiation sarcoma must be considered in patients with uterine carcinoma when a soft tissue mass is seen in the previously irradiated field, especially if the mass is posterior to the sacroiliac joint and the latent period is more than 5 years.

    The reliability of an IUD was examined in 9 women 1-7 days prior to hysterectomy or supracervical amputation of the uterus. An extra large Dana, Dana super, or Dana cor was inserted. All the women complained of hypogastric pains; in 2 cases, the IUD was removed after only a few hours. After the surgery, the uterus was prepared for histological verification of the effects of the IUD. Significant deformation of the uterine wall was found, especially in the region of the cervix and corpus uteri. This was particularly marked with the Dana super, which also caused a rotary deformation. There were changes seen in the IUD itself as well. The results show that an excessively large or incorrectly positioned IUD will cause pronounced deformation of the corpus, uterine cavity and of the cervix with subsequent pains, staining, and expulsion.

    Curie-therapy conventionally comes before surgery in the treatment of cervical cancer, either alone or after a concomitant chemotherapy. The authors report a study of the impact of a reverse sequence (surgery before curie-therapy) on the exeresis quality and on the evolution of operable tumours. Among women treated between 2004 and 2009, 40 have been identified who had surgery before curie-therapy. Ages, tumour stages, average doses, and treatment procedures are discussed. The notably high rate of vaginal sections could be reduced or avoided by using the conventional protocol (curie-therapy before surgery). Short communication

    Purpose : In spite of recent remarkable improvement of diagnostic imaging modalities such as CT, MRI, and PET and radiation therapy planing systems, ICR plan of uterine cervix cancer, based on recommendation of ICRU38(2D film-based) such as point A, is still used widely. A 3-dimensional ICR plan based on CT image provides Dose-Volume Histogram(DVH) information of the tumor and normal tissue. In this study, we compared tumor-dose, rectal-dose and bladder-dose through an analysis of DVH between CTV plan and ICRU38 plan based on CT image. Method and Material : We analyzed 11 patients with a cervix cancer who received the ICR of Ir-192 HDR. After 40Gy of external beam radiation therapy, ICR plan was established using PLATO(Nucletron) v.14.2 planning system. CT scan was done to all the patients using CT-simulator(Ultra Z, Philips). We contoured CTV, rectum and bladder on the CT image and established CTV plan which delivers the 100% dose to CTV and ICRU plan which delivers the 100% dose to the point A. Result : The volume(average{+-}SD) of CTV, rectum and bladder in all of 11 patients is 21.8{+-}6.6cm{sup 3}, 60.9{+-}25.0cm{sup 3}, 111.6{+-}40.1cm{sup 3} respectively. The volume covered by 100% isodose curve is 126.7{+-}18.9cm{sup 3} in ICRU plan and 98.2{+-}74.5cm{sup 3} in CTV plan(p=0.0001), respectively. In (On) ICRU planning 22.0cm{sup 3} of CTV volume was not covered by 100% isodose curve in one patient whose residual tumor size is greater than 4cm, while more than 100% dose was irradiated unnecessarily to the normal organ of 62.2{+-}4.8cm{sup 3} other than the tumor in the remaining 10 patients with a residual tumor less than 4cm in size. Bladder dose recommended by ICRU 38 was 90.1{+-}21.3% and 68.7{+-}26.6% in ICRU plan and in CTV plan respectively(p=0.001) while rectal dose recommended by ICRU 38 was 86.4{+-}18.3% and 76.9{+-}15.6% in ICRU plan and in CTV plan, respectively(p=0.08). Bladder and rectum maximum dose was 137.2{+-}50.1%, 101.1{+-}41.8% in ICRU plan

    Uterine myoma is a common benign tumour in women and most cases do not require treatment. Excessive uterine bleeding is usually due to a submucous myoma or an intramural myoma that is encroaching into the uterine cavity. After eliminating endometrial malignancy, perimenopausal women could be managed expectantly or with gonadotrophin-releasing hormone agonist until menopause. Hysteroscopic myomectomy is highly effective in controlling menorrhagia that is related to submucous myoma. Concomitant endometrial ablation improves menorrhagia; however, the subsequent hysterectomy rate remains the same. For those with an intramural myoma, abdominal myomectomy results in good bleeding control. It could also be done by laparoscopic approach; however, the surgeon should have expertise in laparoscopic suturing and the uterine incision should be properly sutured. In women who have completed their family, hysterectomy remains the most effective treatment for excessive uterine bleeding. Compared with uterine artery embolization (UAE), it is associated with better improvement in pelvic pain. Nevertheless, UAE is a good alternative to hysterectomy.

    To report the first uterine transposition for fertility preservation in a patient with rectal cancer. Case report. Community hospital. A 26-year-old patient with stage cT3N1M0 rectal adenocarcinoma located 5 cm from the anal margin. Laparoscopic transposition of the uterus to the upper abdomen, outside of the scope of radiation, was performed to preserve fertility. After the end of radiotherapy, rectosigmoidectomy was performed and the uterus was repositioned into the pelvis. Uterine and ovarian function preservation. The patient had two menstrual periods and exhibited normal variation in ovarian hormones throughout the course of neoadjuvant therapy. Menstruation began 2 weeks after reimplantation into the pelvis, and the cervix exhibited a normal appearance on clinical examination after 6 weeks. Eighteen months after the surgery, the uterus was normal and there was no sign of disease. Uterine transposition might represent a valid option for fertility preservation in women who require pelvic radiotherapy and want to bear children. However, studies that assess its viability, effectiveness, and safety are required. Copyright © 2017 American Society for Reproductive Medicine. Published by Elsevier Inc. All rights reserved.

    Uterine fibroid is a benign tumour of uterine smooth muscle. The purpose of this review is to bring to light the current spectra of presentation and management status of this benign and very important cause of menstrual and fertility disturbance in African women and the Black race in general. This is especially so with the trivialization of its aetological factors and treatment by claims from alternative medical practitioners. This review, therefore sought to document what is currently known about the condition and what could possibly be done to achieve better results in its management. Literature on the subject above was reviewed using manual library search, electronic books such as CD-ROMS and journals articles published by various local and international authors on the subject; it also included internet search on relevant aspects of the topic. Fibroid is the commonest benign tumour of the female genital tract, it contributes about 70 to 80% of new growths in the female genital tracts, it is a cause of significant morbidity in women of reproductive age group and when complicated could be a significant cause of mortality. Spectrum of presentation mainly involves disturbance of menstruation, reduction in fertility, pressure and obstructive symptoms and rarely malignant presentations. When recognized early effective conservative and definitive therapies are available to offer relief for women and to make their menstrual and reproductive life more meaningful. From the literature reviewed, it was obvious that the subject of uterine fibroid is still not fully exhausted and there were a lot of research questions waiting to be answered on the aetiopathogenesis of the disease. There is also the need to fashion out better treatment alternatives that will reduce morbidity in the process of managing the patient as well as those that will further enhance reproductive potentials after treatment.

    2011-01-01

    Procedures aimed at the treatment of precancerous lesions and ectopia on the uterine cervix are frequently linked to lesions of anatomical structures. The application of hyaluronic acid (Cicatridine vaginal ovules) promotes accelerated healing of the uterine cervix and acquisition of a normal shape in the uterine cervix canal. Local application of hyaluronic acid in the vagina following radiotherapy due to cancer in the uterine cervix or endometrium favourably affects the healing of post-irradiation lesions in the vagina and improves quality of life. Over 90% of patients responded positively to the application of hyaluronic acid in the form of a cream on dystrophic lesions in the vulva. Hyaluronic acid aids the healing process of post-procedural wounds in the uterine cervix, following radiotherapy applied due to cancer of the uterine cervix, endometrium and in vulvar dystrophy.

    Primary uterine non-Hodgkin's lymphoma is extremely rare accounting for CT findings in a patient with primary uterine peripheral T-cell lymphoma.A 27-year-old female presented with intermittent fever with neutropenia for 7 months. MRI showed an ill-defined mass involved both the uterine corpus and cervix, resulting in diffuse enlargement of the uterus. This mass showed inhomogeneous hypointensity on unenhanced T1-weighted images, hyperintensity on diffusion-weighted imaging, relative hypointensity compared to the surrounding myometrium on T2-weighted images and lower enhancement than the surrounding myometrium on enhanced T1-weighted images. FDG PET/CT showed intense FDG uptake in the thickened wall of the uterine corpus and cervix with SUVmax of 26.9. There were multiple hypermetabolic lymph nodes in the pelvis and retroperitoneum. Uterine curettage and CT-guided biopsy of the uterine mass revealed peripheral T-cell lymphoma. Bone marrow biopsy revealed no evidence of lymphomatous involvement. The imaging and pathologic findings were consistent with primary uterine lymphoma. After 3 circles of chemotherapy, follow-up enhanced MRI showed decreased thickness of the uterine wall.Despite its rarity, primary uterine non-Hodgkin's lymphoma should be taken into consideration when a uterine tumor shows large size, relative hypointesity on both T2-weighted images and enhanced T1-weighted images compared to the surrounding myometrium, and intense FDG uptake on PET/CT. MRI may be helpful for describing the relationship between the tumor and adjacent structures. FDG PET/CT may be useful for tumor detection and staging.

  19. Glandular epithelial AR inactivation enhances PTEN deletion-induced uterine pathology.

    Phosphatase and tensin homolog (PTEN) deletion induces uterine pathology, whereas androgen actions via androgen receptor (AR) support uterine growth and therefore may modify uterine cancer risk. We hypothesized that the androgen actions mediated via uterine glandular epithelial AR could modify PTEN deletion-induced uterine pathology. To test our hypothesis, we developed uterine glandular epithelium-specific PTEN and/or AR knockout mouse models comparing the uterine pathology among wild-type (WT), glandular epithelium-specific AR inactivation (ugeARKO), PTEN deletion (ugePTENKO), and the combined PTEN and AR knockout (ugePTENARKO) female mice. The double knockout restricted to glandular epithelium showed that AR inactivation enhanced PTEN deletion-induced uterine pathology with development of intraepithelial neoplasia by 20 weeks of age. In ugePTENARKO, 6/10 (60%) developed intraepithelial neoplasia, whereas 3/10 (30%) developed only glandular hyperplasia in ugePTENKO uterus. No uterine pathology was observed in WT (n=8) and ugeARKO (n=7) uteri. Uterine weight was significantly (P=0.002) increased in ugePTENARKO (374±97 mg (mean±s.e.)) compared with WT (97±6 mg), ugeARKO (94±12 mg), and ugePTENKO (205±33 mg). Estrogen receptor alpha (ERα) and P-AKT expression was modified by uterine pathology but did not differ between ugePTENKO and ugePTENARKO, suggesting that its expressions are not directly affected by androgens. However, progesterone receptor (PR) expression was reduced in ugePTENARKO compared to ugePTENKO uterus, suggesting that PR expression could be regulated by glandular epithelial AR inactivation. In conclusion, glandular epithelial AR inactivation (with persistent stromal AR action) enhanced PTEN deletion-induced uterine pathology possibly by downregulating PR expression in the uterus.

    Building a training system for medical personnel to properly interpret fetal heart rate tracing requires developing accurate models that can relate various signal patterns to certain pathologies. In addition to modeling the fetal heart rate signal itself, the change of uterine pressure that bears strong relation to fetal heart rate and provides indications of maternal and fetal status should also be considered. In this work, we have developed a group of parametric models to simulate uterine contractions during labor and delivery. Through analysis of real patient records, we propose to model uterine contraction signals by three major components: regular contractions, impulsive noise caused by fetal movements, and low amplitude noise invoked by maternal breathing and measuring apparatus. The regular contractions are modeled by an asymmetric generalized Gaussian function and least squares estimation is used to compute the parameter values of the asymmetric generalized Gaussian function based on uterine contractions of real patients. Regular contractions are detected based on thresholding and derivative analysis of uterine contractions. Impulsive noise caused by fetal movements and low amplitude noise by maternal breathing and measuring apparatus are modeled by rational polynomial functions and Perlin noise, respectively. Experiment results show the synthesized uterine contractions can mimic the real uterine contractions realistically, demonstrating the effectiveness of the proposed algorithm.

    The uterine atony are the most common cause of postpartum hemorrhage. Manual compression and pharmacologic methods are usually used with a successful result. When pharmacologic methods fail to control hemorrhage from atony, surgical measures should be undertaken to arrest the bleeding before it becomes life-threatening. We presents the utilization of electrical uterine defibrillation in two cases with acute hemorrhage confirming the effectivity of the proceeding.

    To determine the efficacy and clinical outcome of uterine arterial embolization as a new approach to the management of uterine leiomyomas. Uterine arterial embolization was performed in 21 patients aged 26-62(mean, 42) years. Twenty of these had menorrhagia, dysmenorrhea, and mass-related symptoms (low abdominal discomfort, backache, urinary frequency, etc.) and one was diagnosed incidentally. Bilateral uterine arteries were selected individually and polyvinyl alcohol and/or gelfoam was used as an embolic material. Nineteen patients were followed up after embolization. Seventeen (89.5 %)reported satisfactory improvement of symptoms and follow-up sonography three months later showed a 58.5 % reduction in mean myoma volume. In 17 patients (89.5 %), the menstrual cycle returned to normal. All patients experienced pain after the procedure and other complications were vaginal bleeding (26.3 %) and fever (23.8 %). Uterine arterial embolization represents a new approach to the management of uterine leiomyoma-related symptoms. Further investigations and long-term follow-up are, however, enquired.

    Background. Polycystic ovary syndrome (PCOS) is associated with chronic oligo-anovulation and high circulating sex hormone levels. Women with PCOS have an increased risk of developing endometrial cancer. In anovulatory women with PCOS a positive relationship between endometrial thickness and endometrial hyperplasia has been observed. Uterine peristalsis, which has been suggested to be of importance for female fertility, has not previously been studied in PCOS. Purpose. To assess whether women with PCOS have altered endometrial thickness, uterine wall morphology, and peristalsis. Material and Methods. In this prospective case-control study 55 women with PCOS (mean age, 29.5 years {+-} 4.5 SD) and 28 controls (27.6 {+-} 3.2) were examined using magnetic resonance imaging (MRI), assessing thickness of endometrium, junctional zone (JZ), and myometrium, and evaluating the occurrence, frequency (waves/min), strength (amplitude), pattern, and direction of peristalsis. Uterine morphology was also assessed by transvaginal ultrasonography (TVUS). Results. The endometrium was thinner in PCOS with oligo-amenorrhea compared to controls, also after adjustments for age and BMI (adjusted P = 0.043). There was no difference in thickness of the JZ or the myometrium in cases versus controls. Uterine peristalsis was less commonly observed in women with PCOS than in controls (adjusted P = 0.014). Conclusion. There were no differences in myometrial morphology between PCOS and controls, but the endometrium was thinner in PCOS with oligo-amenorrhea. Based on cine MRI, uterine peristalsis was less common in PCOS than in controls.

    Full Text Available Perivascular epithelioid cell tumors (PEComa are mesenchymal tumors composed of histologically and immunohistochemically distinctive perivascular epithelial cells. Although the uterine corpus seems to be one of the most prevalent sites of involvement, PEComa of the uterine cervix are very rare. Only four cervical PEComa cases have been described, and were treated with hysterectomy and radiotherapy. We report a case of a 24-year-old nulli­gravida woman who presented with acute abdominal pain and was diagnosed with a rupture of an ovarian chocolate cyst. Subsequent surgery revealed that the tumor arose in the uterus, and the histological diagnosis was uterine PEComa with low potential malignancy. Recurrent PEComa in the uterine cervix were excised twice, and she remains disease free 12 months after the last operation. To the best of our knowledge, this is the first report of recurrent cervical PEComa with fertility-preserving surgery. Estimating the malignant potential and appropriate surgery are essential for young patients with uterine PEComa.

We found that in a significant number of cases, the uterine cavity is colonized with potentially pathogenic organisms...... which may play a causative role in endometritis. The results indicate that inflammation of the uterine cavity should be evaluated by hysteroscopic examination before hysterectomy is undertaken in patients with persistent irregular vaginal bleeding.

  15. Postpartum uterine health in cattle.

    Sheldon, I M; Dobson, H

    2004-07-01

    Uterine health is often compromised in cattle because postpartum contamination of the uterine lumen by bacteria is ubiquitous, and pathogenic bacteria frequently persist causing clinical disease. The subfertility associated with uterine infection involves perturbation of the hypothalamus, pituitary and ovary, in addition to the direct effects on the uterus, and appears to persist even after clinical resolution of the disease. Absorption of bacterial components from the uterus can prevent the follicular phase LH surge and ovulation. In addition, the first postpartum dominant follicle has a slower growth rate and secretes less estradiol at the end of the growth phase. There are also localised ovarian effects of high uterine bacterial growth density, because fewer first dominant follicles are selected in the ovary ipsilateral than contralateral to the previously gravid uterine horn. Thus, it is important to diagnose and treat uterine disease promptly and effectively. Examination of the contents of the vagina for the presence of pus is the most useful method for diagnosis of endometritis. The character and odor of the vaginal mucus can be scored and this endometritis score is correlated with the growth density of pathogenic bacteria in the uterus, and is prognostic for the likely success of treatment. The challenge for the future is to design prevention and control programs to reduce the incidence of disease, and understand how the immune and endocrine systems are integrated.

    Traditionally, vaginal hysterectomy and Manchester repair were the surgical approaches to treating uterine prolapse; however, both are associated with a relatively high subsequent vaginal vault recurrence. Laparoscopic uterine suspension is a new way of maintaining uterine support. Many women are keen to keep their uterus for a variety of reasons, including maintaining reproductive capability and the belief that the uterus, cervix, or both, may play a part of their gender identity. Non-removal of the uterus may retain functional (e.g. bowel, bladder and sexual) benefits. Therefore, the concept of uterine preservation for pelvic-organ prolapse has been of interest to pelvic-floor surgeons for many decades. In this review, we provide an overview of the available evidence on treating uterine prolapse surgically. We describe techniques to support the vault during hysterectomy, and examine the evidence for uterine-sparing surgery. Comparative outcomes for vaginal, abdominal and laparoscopic routes will be made. Copyright © 2012 Elsevier Ltd. All rights reserved.

    子宫是孕育胚胎、胎儿和产生月经的器官.同时,子宫也是容易发生恶性肿瘤的器官.从子宫颈到子宫体,子宫内膜到子宫肌层,各部位均可发生恶性肿瘤.宫颈癌是最常见的妇科恶性肿瘤,高危型人乳头瘤病毒(HPV)的持续性感染是引起宫颈癌前病变和宫颈癌的主要原因.宫颈癌的主要病理类型为鳞状细胞癌和腺癌,确诊依赖于宫颈病灶的活体组织病理检查,对病变程度的判断采用国际妇产科联盟(FIGO)的临床分期.宫颈癌的治疗早期以手术为主,中、晚期以放疗为主,辅以化疗的综合治疗.近年来靶向治疗为局部晚期、复发性、转移性宫颈癌提供了新的治疗途径.HPV疫苗也已开始应用于宫颈癌的预防.%The uterus is an organ which nurtures the embryo,fetus and produces menstruation. At the same time.it is also an organ which is likely to suffer from malignant tumor. Each part of the uterus including cervix,corpus uteri,endometrium,myometrium is prone to malignant tumor. Cervical cancer is the most common gynecological malignancies. Persistent infection of high risk papillomavirus is the main reason of precancerous and cervical cancer. The main pathological type was squamous cell carcinoma and adenocarcinoma. Definite diagnosis can depend on cervix biopsy and histopathology. We can judge the severity from the FICO clinical staging. The treatment of early stage cervical cancer is surgery,while in treatment of the middle and advanced stage cervical cancer,radiaotherapy is the core and chemotherapy is the complement. Nowadays targeted therapy provides a new approach to local advanced,recurrent and metastasis cervical cancer. HPV vaccine has been used to prevent the cervical cancer now.

    Full Text Available Carotenoids and retinyl esters are the source of vitamin A in the human body and its natural derivatives takes part in the regulation of cell replication and differentiation in the human endometrium, may induce the leiomyoma growth and has a role in differentiation of endometrial adenocarcinoma. The aim of the study was to demonstrate the presence of carotenoids in tissues from the normal uterus and from various tumors of the uterine corpus, as well as to compare the total content, major carotenoids and % of carotenoids belonging to the provitamin A group between the tissues examined. Using three independent methods of chromatography (CC, TLC, HPLC we analysed 140 human samples. We identified 13 carotenoids belonging to the eg. provitamin A group and epoxy carotenoids. In all the samples beta-carotene, beta-cryptoxanthin, lutein, neoxanthin, violaxanthin and mutatoxanthin were isolated. In normal tissues, the mean carotenoid content was the highest in the follicular phase endometrium (9.9 microg/g, while the highest percentage of carotenoids belonging to provitamin A group was found in the luteal phase (18.2%. In the pathological group, the highest mean values were demonstrated for epithelial lesions (8.0 microg/g, and within this group - in endometrioid adenocarcinoma (10.8 microg/g. In both groups, violaxanthin, beta-cryptoxanthin, lutein epoxide and mutatoxanthin were the predominant carotenoids. We have demonstrated that all uterine tissues show a concentration of beta-carotene and beta-cryptoxanthin, being the source of vitamin A. The highest total values of carotenoids obtained in the group of endometrioid adenocarcinoma seem to confirm certain enzymatic defects in carotenoid metabolism in the course of the neoplastic process or some metabolic modifications. The finding of astaxanthin - the major antioxidant among carotenoids - in 63% of tissues examined is also significant.

    Full Text Available Abstract The corpus luteum (CL is a site of intense angiogenesis. Within a short period, this is followed either by controlled regression of the microvascular tree in the non-fertile cycle, or maintenance and stabilisation of the new vasculature a conceptual cycle. The molecular regulation of these diverse aspects is examined. The CL provides a unique model system in which to study the cellular and molecular regulation of angiogenesis. Vascular endothelial growth factor (VEGF has been found to have a major role in the CL. By targeting its action at specific stages of the luteal phase in vivo by antagonists, profound inhibitory effects on luteal angiogenesis and function are observed.

  6. Target Therapies for Uterine Carcinosarcomas: Current Evidence and Future Perspectives

    2017-05-01

    Full Text Available Carcinosarcomas (CS in gynecology are very infrequent and represent only 2–5% of uterine cancers. Despite surgical cytoreduction and subsequent chemotherapy being the primary treatment for uterine CS, the overall five-year survival rate is 30 ± 9% and recurrence is extremely common (50–80%. Due to the poor prognosis of CS, new strategies have been developed in the last few decades, targeting known dysfunctional molecular pathways for immunotherapy. In this paper, we aimed to gather the available evidence on the latest therapies for the treatment of CS. We performed a systematic review using the terms “uterine carcinosarcoma”, “uterine Malignant Mixed Müllerian Tumors”, “target therapies”, “angiogenesis therapy”, “cancer stem cell therapy”, “prognostic biomarker”, and “novel antibody-drug”. Based on our results, the differential expression and accessibility of epithelial cell adhesion molecule-1 on metastatic/chemotherapy-resistant CS cells in comparison to normal tissues and Human Epidermal Growth Factor Receptor 2 (HER2 open up new possibilities in the field of target therapy. Nevertheless, future investigations are needed to clarify the impact of these new therapies on survival rate and medium-/long-term outcomes.

    The purposes of this study were to estimate the infection frequency of Human Papilomavirus (HPV) and to identify the viral types in patients with diagnosis of uterine cervical cancer (UCC) and High Grade Squamous Intraepitelial lesions (HGSILs), and to correlate the molecular findings versus HPV infection suggestive clinical findings. Biopsies from 50 patients (37 HGSILs and 13 UCC) histopathologically diagnosed were studied. The presence of HPV were detected by means of the polymerase chain reaction (PCR) using consensus primers for types 6, 11, 16, 18, 31, 33, 35, and 58 among others, as well as specific primers for some of them. The frequencies for HPV 16, 18, 33, 35, and 58 in HGSIL samples were 24.3, 2.7, 0, 5.4 and 16.2% respectively. In UCC samples were 61.5, 7.7, 0, 0 and 15.4% with significative differences only for HPV 16. Clinical findings (histologic, colposcopic and histopathologic), showed deficient diagnostic accuracy in the identification of HPV 16 in HGSIL, wich resulted less frequent and there is a high frequency of HPV. These results are similar to those previously described in our country and the other populations, with the exception of HPV16 in HGSIL, wich resulted less frequent and there is a high frequency of HPV 58 in our region. When analyzing clinical features with the presence of HPV DNA, we conclude that these are insufficient to discard or establish the possibility of HPV infection in patients with HGSIL's and UUC.

    Uterine fibroids or uterine leiomyomas are the most common benign tumors of the uterus among women of fertile age, while the etiology is still incompletely elucidated. The occurrence and development of the fibromatosis may be related to certain risk factors and genic mechanisms, although the exact causes are not yet fully known. The development of uterine fibroids is correlated not only with the metabolism and with the level of female sexual hormones, estrogen, and progesterone, but also with the number of these hormone receptors expressed on the surface of the myometrium. Proliferative effects of estrogen and progesterone may be exercised through proinflammatory factors (TNF alpha), growth factors (IGF1, IGF2, TGFbeta3 and betaFGF) or inhibitors of apoptosis (p53 suppression). A number of predisposing factors such as ethnicity – black skin, early menarche, nulliparity, caffeine and alcohol, chronic inflammation, obesity, were also identified. Approximately 40% of the uterine fibroids are caused by the same cytogenetic alterations found in the other tumor types such as kidney, lung, or leiomyosarcoma. As part of a system dysfunction, uterine fibromatosis was connected to other disorders such as AHT (arterial hypertension), endometrium adenocarcinoma, adenomyosis, endometriosis, diabetes mellitus, breast tumors, seemingly with a common causality. The action and effect of some hormonal imbalances over the various organs depend on the histological and local expression particularities of the various receptors, being the cause for many disorders, among which the uterine fibromatosis, coexisting or accompanying the later. This article examines and summarizes the latest data refreshed literature etiopathogenesis offering indicators of uterine fibroids. PMID:27974911

    Site-specific cancer incidence rats were computed by sex, age, and marital status for whites and blacks separately for ages 35-64 years with the use of population-based incidence data from the Third National Cancer Survey (1969-71) and with demographic data from the 1970 U.S. Census. Although rates were presented for all cancer sites combined and for 44 specific sites or rubrics, discussion focused on the 17 most common cancers. Within age, race, and sex groups, patterns of cancer incidence by marital status were compared by means of standardized incidence ratios, and the consistency of marital status patterns across age groups was assessed statistically. Among the most notable findings were: excess cancer rates across most sites and age groups in single black males, consistently high rates for cancer of the lung and bronchus in divorced white males and in single black females, low rates for the hormone-dependent reproductive tumors (prostate gland, breast, uterine corpus, and ovary) in separated white males and females, and high rates for cervical cancer among separated white women. Marital status patterns, where found, frequently differed between whites and blacks and between males and females.

    controle locorregional da doença na pelve.PURPOSE: to assess to what extent the surgical staging differs from the clinical staging among cases of advanced uterine cervix carcinoma, and also to assess the percentage of cases with positive para-aortic ganglia in this group of patients. METHODS: this is a descriptive prospective study in which 36 patients with histological diagnosis of uterine cervix carcinoma considered locally advanced were included (stages IB2, IIB, IIIA and B, and IVA. The cases were submitted to clinical staging, according to FIGO criteria. All patients were to be treated with neoadjuvant chemotherapy. Age ranged from 40 to 73 years, with a mean of 56.2±7.9. The procedure started with pelvic lymphadenectomy followed by para-aortic lymphadenectomy, in case the pelvic lymph nodes were positive on surgical examination. Examination of the abdominal cavity and lymphadenectomy were done either through laparotomy or laparoscopy, chosen at random. In each case, the clinical staging was compared to the surgical staging, considered the gold standard. RESULTS: in the clinical staging (CS, 7 cases were classified as IB2 (tumors larger than 4 cm, 22 cases as CSII and 7 cases as CSIII. The surgical assessment changed the clinical staging as follows: the stage was decreased in six cases, and increased in 13. There was agreement only in 18 cases (50%. The para-aortic lymph nodes were affected in six cases. CONCLUSIONS: clinical staging of locally advanced uterine cervix carcinoma is incorrect in most of the cases. Such inconsistency may lead to excessive treatment in some cases, but about one fourth of the patients with positive para-aortic ganglia would not be adequately treated with the current standard treatment radiotherapy with chemosensitization, which aims at the local regional control of the pelvic disease.

    Full Text Available OBJECTIVE: To evaluate pregnancy outcomes, complications and neonatal outcomes in women who had previously undergone uterine arterial embolization. METHODS: A retrospective study of 187 patients treated with uterine arterial embolization for symptomatic uterine fibroids between 2005-2008 was performed. Uterine arterial embolization was performed using polyvinyl alcohol particles (500-900 mm in diameter. Pregnancies were identified using screening questionnaires and the study database. RESULTS: There were 15 spontaneous pregnancies. Of these, 12.5% were miscarriages (n = 2, and 87.5% were successful live births (n = 14. The gestation time for the pregnancies with successful live births ranged from 36 to 39.2 weeks. The mean time between embolization and conception was 23.8 months (range, 5-54. One of the pregnancies resulted in twins. The newborn weights (n = 14 ranged from 2.260 to 3.605 kg (mean, 3.072 kg. One (7.1% was considered to have a low birth weight (2.260 kg. There were two cases of placenta accreta (12.5%, treated with hysterectomy in one case [6.3%], one case of premature rupture of the membranes (PRM (6.3%, and one case of preeclampsia (6.3%. All of the patients were delivered via Cesarean section. CONCLUSION: In this study, there was an increased risk of Cesarean delivery. There were no other major obstetric risks, suggesting that pregnancy after uterine arterial embolization is possible without significant morbidity or mortality.

    Conclusion: Many studies have been reported that uterine artery embolization for postpartum hemorrhage did not affect subsequent pregnancy outcomes. However, we report that this procedure contains a potential risk for asymptomatic uterine rupture in a subsequent pregnancy. Although it is difficult to diagnose uterine rupture without symptoms, the obstetrician should be aware of the possibility of uterine rupture.

    2009-05-15

    Background: Accumulation of 18F-fluorodeoxyglucose (18F-FDG) in the uterine endometrium and uterine motility are dependent on menstrual cycle. However, the relationship between them remains unknown. Purpose: To investigate the relationship between radiometabolic activity of 18F-FDG in the uterus and uterine motility observed by cine magnetic resonance imaging (MRI). Material and Methods: The study population consisted of 65 healthy, fertile women, selected from 229 women who underwent positron emission tomography (PET), computed tomography (CT), and MRI for cancer screening at our facility. They were divided into three groups according to their menstrual cycle phases: menstrual, follicular-periovulatory, and luteal. Regions of interest (ROIs) were placed over the endometrium and myometrium to calculate the standardized uptake value (SUV). Uterine peristalsis and contraction shown by cine MR imaging were evaluated visually, and the correlation between FDG uptake and uterine movements was assessed. Results: After excluding nine patients due to inadequate images, 56 patients (19 follicular-periovulatory, 27 luteal, and 10 menstrual) were analyzed. FDG uptake of the endometrium, frequency of peristalsis, and the presence of sustained contraction varied according to the menstruation cycle, with a tendency toward greater uptake in the menstrual phase, but there was little relationship between the frequency of uterine peristalsis and FDG accumulation in the uterus. Significantly higher FDG accumulation in the endometrium was observed in patients with sustained contractions (3.32+-1.47) than in those without contractions (2.45+-0.66). Conclusion: Our preliminary data suggest that FDG accumulation in the endometrium tends to be higher in patients with uterine contraction, although there was no significant correlation between uterine peristalsis and FDG uptake in the uterine myometrium or endometrium

  17. Infertility and uterine fibroids.

    2016-07-01

    Uterine fibroids are the most common tumors in women and their prevalence is higher in patients with infertility. At present, they are classified according to their anatomical location, as no classification system includes additional parameters such as their size or number. There is a general agreement that submucosal fibroids negatively affect fertility, when compared to women without fibroids. Intramural fibroids above a certain size (>4 cm), even without cavity distortion, may also negatively influence fertility. However, the presence of subserosal myomas has little or no effect on fertility. Many possible theories have been proposed to explain how fibroids impair fertility: mechanisms involving alteration of local anatomical location, others involving functional changes of the myometrium and endometrium, and finally endocrine and paracrine molecular mechanisms. Nevertheless, any of the above mentioned mechanisms can cause reduced reproductive potential, thereby leading to impaired gamete transport, reduced ability for embryo implantation, and creation of a hostile environment. The published experience defines the best practice strategy, as not many large, well-designed, and properly powered studies are available. Myomectomy appears to have an effect in fertility improvement in certain cases. Excision of submucosal myomas seems to restore fertility with pregnancy rates after surgery similar to normal controls. Removal of intramural myomas affecting pregnancy outcome seems to be associated with higher pregnancy rates when compared to non-operated controls, although evidence is still nοt sufficient. Treatment of subserosal myomas of reasonable size is not necessary for fertility reasons. The results of endoscopic and open myomectomy are similar; thus, endoscopic treatment is the recommended approach due to its advantages in patient's postoperative course.

    Uterine fluid was obtained from eight clinical cases of pyometra with retained corpus luteum and nine additional samples of fluid were collected from animals slaughtered at an abattoir. These samples, along with uterine flushes from normal cows in their luteal phase were analyzed for prostaglandin of the F (PGF) and E (PGE) groups. Blood samples were also obtained from the clinical cases for analysis of 13,14-dihydro-15-keto PGF (PGFM) the major metabolite of PGF. Pyometrial exudate from clinical cases of abattoir samples had high concentrations of PGF (17.9 ng/mL) and PGE (33.2 ng/mL) and the total amount of PGF and PGE in the uterus was calculated to be several hundred times as great as in normal cows. Furthermore, clinical cases had elevated PGFM in their blood compared to that of controls, which suggests that at least some of the PGF was being absorbed from the uterus. These results are discussed in light of our current understanding of the maternal recognition of pregnancy in cattle. PMID:4075244

    Uterine prolapse during pregnancy is an uncommon condition. It can cause preterm labor, spontaneous abortion, fetal demise, maternal urinary complication, maternal sepsis and death. We report the case of uterine prolapse in a 32-year-old healthy primigravid woman. She had no risk factors associated with uterine prolapse. She was conservatively treated, resulting in a successful vaginal delivery. This report is a very rare case of uterine prolapse in a young healthy primigravid woman, resulting in a successful vaginal delivery.

    Full Text Available Spontaneous uterine rupture is a life-threatening obstetrical emergency carrying a high risk for the mother and the fetus. Spontaneous uterine rupture in early pregnancy is very rare complication and it occurs usually in scarred uterus. Uterine anomalies are one of the reasons for spontaneous unscarred uterine rupture in early pregnancy. Obstetricians must consider this diagnosis when a pregnant patient presented with acute abdomen in early pregnancy. We present a case of spontaneous uterine rupture at 12 weeks of gestation in 24-year-old multigravida who had uterine anomaly presenting as an acute abdomen. Our preoperative diagnosis was ectopic pregnancy. Emergency laparotomy confirmed a spontaneous uterine rupture. Uterine anomaly is a risk factor for spontaneous uterine rupture in the early pregnancy. Clinical signs of uterine rupture in early pregnancy are nonspecific and must be distinguished from acute abdominal emergencies.

    Full Text Available The Bulgarian-Polish-Russian parallel corpus The Semantics Laboratory Team of Institute of Slavic Studies of Polish Academy of Sciences is planning to begin work on the creation of a Bulgarian-Polish-Russian parallel corpus. The three selected languages are representatives of the main groups of Slavic languages: Bulgarian represents the southern group of Slavic languages, Polish – the western group of Slavic languages, Russian – the eastern group of Slavic languages. Our project will be the first parallel corpus of these three languages. The planned corpus will be based on material, dating from one period (the 20th century and will have a synchronous nature. The project will not constitute the sum of the separate corpora of selected languages. One of the problems with creating multilingual parallel corpora are different proportions of translated texts between the selected languages, for example, Polish literature is often translated into Bulgarian, but not vice versa. Bulgarian, Russian and Polish differ typologically – Bulgarian is an analytic language, Polish and Russian are synthetic. The parallel corpus should have compatible annotation, while taking into account the characteristic features of the selected languages. We hope that the Bulgarian-Polish-Russian parallel corpus will serve as a source of linguistic material of contrastive language studies and may prove to be a big help for linguists, translators, terminologists and students of linguistics. The results of our work will be available on the Internet.

    Full Text Available Background: medical translation has countless documentary sources; the major difficulty lies in knowing how to assess them. The corpus is the ideal tool to perform this activity in a rapid and reliable way, and to define the learning objectives based on text typology and oriented towards professional practice.Objective: to compile an electronic corpus that meets the requirements of the professional practice to perform specialized medical translation. Methods: a pedagogical research was conducted in the province of Cienfuegos. The units of analysis involved records from translators of the Provincial Medical Sciences Information Center and specialized translators in this field, who completed a questionnaire to accurately determine their information needs, conditioning the corpus design criteria. The analysis of a set of texts extracted from highly reputable sources led to the text selection and final compilation. Subsequently, the validation of the corpus as a documentary tool for teaching specialized medical translation was performed. Results: there was a concentration of translation assignments in the topics: malignant tumors, hypertension, heart disease, diabetes mellitus and pneumonias. The predominant text typologies were: evaluative and dissemination of current research, with plenty original articles and reviews. The text corpus design criteria were: unannotated, documented, specialized, monitor and comparable. Conclusions: the corpus is a useful tool to show the lexical, terminological, semantic, discursive and contextual particularities of biomedical communication. It allows defining learning objectives and translation problems. Key words: teaching; translating; medicine

    Full Text Available The use of PGF2 α is based on its luteolytic effect causing regression of corpus luteum and allows development of dominant follicle on the ovary that result in estrus and ovulation in 72 to 96 hours after its administration. Moreover, the PGF2 α also causes relaxation of cervix and smooth muscle contractions of uterus. The use of PGF2 α may provide microbial resistance in uterine environment, on one hand and can favour and enhance body defense mechanism / phagocytic activity on the other hand. PGF2 α is widely used to get rid of from the conditions like luteal cystic ovarian disease, persistent corpus luteum, endometritis, abnormal pregnancy, pyometra, retention of placenta and mummification. It has been now in vogue to administer PGF2 α or its analogue in early postpartum cows and buffaloes in order to hasten early resumption of cyclic ovarian activity and thereby to increase the reproductive efficiency.

    Purpose: To determine the efficacy of a definitive radiotherapy protocol using high-dose-rate intracavitary brachytherapy (HDR-ICBT) with a low cumulative dose schedule in nonbulky early-stage cervical cancer patients, we conducted a prospective multi-institutional study. Methods and Materials: Eligible patients had squamous cell carcinoma of the intact uterine cervix, Federation of Gynecologic Oncology and Obstetrics (FIGO) stages Ib1, IIa, and IIb, tumor size <40 mm in diameter (assessed by T2-weighted magnetic resonance imaging), and no pelvic/para-aortic lymphadenopathy. The treatment protocol consisted of whole-pelvis external beam radiotherapy (EBRT) of 20 Gy/10 fractions, pelvic EBRT with midline block of 30 Gy/15 fractions, and HDR-ICBT of 24 Gy/4 fractions (at point A). The cumulative biologically effective dose (BED) was 62 Gy{sub 10} ({alpha}/{beta} = 10) at point A. The primary endpoint was the 2-year pelvic disease progression-free (PDPF) rate. All patients received a radiotherapy quality assurance review. Results: Between September 2004 and July 2007, 60 eligible patients were enrolled. Thirty-six patients were assessed with FIGO stage Ib1; 12 patients with stage IIa; and 12 patients with stage IIb. Median tumor diameter was 28 mm (range, 6-39 mm). Median overall treatment time was 43 days. Median follow-up was 49 months (range, 7-72 months). Seven patients developed recurrences: 3 patients had pelvic recurrences (2 central, 1 nodal), and 4 patients had distant metastases. The 2-year PDPF was 96% (95% confidence interval [CI], 92%-100%). The 2-year disease-free and overall survival rates were 90% (95% CI, 82%-98%) and 95% (95% CI, 89%-100%), respectively. The 2-year late complication rates (according to Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer of Grade {>=}1) were 18% (95% CI, 8%-28%) for large intestine/rectum, 4% (95% CI, 0%-8%) for small intestine, and 0% for bladder.

Os resultados mostraram discreta redução da mortalidade por câncer do colo do útero, queda da mortalidade por câncer de útero não especificado e aumento da mortalidade por câncer do corpo do útero. Conclui-se que a queda da mortalidade por câncer do útero não especificado sinaliza uma melhora na precisão do diagnóstico clínico e na qualidade do preenchimento do atestado de óbito, e indica aumento de cobertura do teste de Papanicolaou.Uterine cervical cancer shows a higher incidence in some Brazilian cities. It is a common cause of death in women from developing countries, despite the longstanding availability of an effective screening test, the Pap smear. This study aimed to evaluate the temporal trends of crude, age-adjusted, and age-specific mortality rates from cervical cancer, endometrial cancer, and cancer of the uterus not otherwise specified (NOS in the city of São Paulo from 1980 to 1999. Results showed a slight reduction in cervical cancer rates, a decrease in NOS uterine cancer rates, and an increase in endometrial cancer mortality rates. The fall in mortality from NOS uterine cancer indicates an improvement in diagnostic accuracy and quality of information on death certificates and may point to an increase in coverage of cervical cancer screening using the Pap smear.

  18. Microvascular endothelial cells of the corpus luteum

    2003-11-01

    Full Text Available Abstract The cyclic nature of the capillary bed in the corpus luteum offers a unique experimental model to examine the life cycle of endothelial cells, involving discrete physiologically regulated steps of angiogenesis, blood vessel maturation and blood vessel regression. The granulosa cells and theca cells of the developing antral follicle and the steroidogenic cells of the corpus luteum produce and respond to angiogenic factors and vasoactive peptides. Following ovulation the neovascularization during the early stages of corpus luteum development has been compared to the rapid angiogenesis observed during tumor formation. On the other end of the spectrum, the microvascular endothelial cells are the first cells to undergo apoptosis at the onset of corpus luteum regression. Important insights on the morphology and function of luteal endothelial cells have been gained from a combination of in vitro and in vivo studies on endothelial cells. Endothelial cells communicate with cells comprising the functional unit of the corpus luteum, i.e., other vascular cells, steroidogenic cells, and immune cells. This review is designed to provide an overview of the types of endothelial cells present in the corpus luteum and their involvement in corpus luteum development and regression. Available evidence indicates that microvascular endothelial cells of the corpus luteum are not alike, and may differ during the process of angiogenesis and angioregression. The contributions of vasoactive peptides generated by the luteal endothelin-1 and the renin-angiotensin systems are discussed in context with the function of endothelial cells during corpus luteum formation and regression. The ability of two cytokines, tumor necrosis factor alpha and interferon gamma, are evaluated as paracrine mediators of endothelial cell function during angioregression. Finally, chemokines are discussed as a vital endothelial cell secretory products that contribute to the recruitment of

    Tissue inhibitor of matrix metalloproteinase-2 (TIMP-2) has high affinity for matrix metalloproteinase-2 (MMP-2). Few studies simultaneously investigate their implication in prognosis of patients with cervical cancer. We used reverse transcription-polymerase chain reaction and immunohistochemical method for cervical tissues and microarrays to investigate the association among TIMP-2, MMP-2, clinicopathological parameters, and prognosis of patients with cancer. Our results showed that cancer tissues exhibited less TIMP-2 expression and patients with pelvic lymph node metastasis had less TIMP-2 expression. Positive TIMP-2 constellated with negative MMP-2 indicated lower recurrence probability and better overall survival. The protective effect of TIMP-2 expression may overcome the adverse effect of MMP-2 expression in terms of disease-free interval and overall survival while neither TIMP-2 nor MMP-2 alone can be used to predict outcome. We suggest that following patients other than those with positive TIMP-2 and negative MMP-2 expression more closely and intensely may improve their prognosis.

    To define and classify cervical elongation, to compare uterine measurements after prolapse hysterectomy with a non-prolapse control group, and to associate stage of prolapse and degree of cervical elongation. This was a single-centre retrospective case-control study conducted at the University Hospital, Urogynaecological Unit, with a certified urogynaecological surgeon. Data were collected from patients with and without pelvic organ prolapse (POP) who underwent laparoscopically assisted vaginal hysterectomy. Post-hysterectomy uterine cervical elongation was examined using the corpus/cervix ratio (CCR), calculated from measurements taken on photographs. Cervical elongation was classified as physiological (grade 0, CCR>1.5) grade I (CCR>1 and ≤1.5) grade II (CCR>0.5 and ≤1), and grade III (CCR≤0.5). Cervical elongation was detected in 288/295 (97.6%) patients in the prolapse group (grade I, 44/288 [15.2%]; grade II, 212 [73.6%]; grade III, 32 [11.1%]). Mean CCR was greater among those with stage II/III than among those with stage IV prolapse (1.0±0.4 vs. 0.8±0.2; pprolapse stages were associated (pprolapse group compared to the control group (puterine length did not differ between the prolapse and control groups (8.0±1.6 vs. 8.2±1.3cm), but mean calculated cervical length was greater in the prolapse group than in the control group (4.4±1.1 vs. 3.1+0.8cm; pUterine cervical elongation is found in patients undergoing hysterectomy for pelvic organ prolapse. Cervical elongation grades and prolapse stages are correlated. Defining uterine cervical elongation based on corpus/cervix ratio with grades I-III could be a valuable basic tool for further research.

    The purpose of the study was to perform a node-by-node comparison of an ADC-based diagnosis and various size-based criteria on T2-weighted imaging (T2WI) with regard to their correlation with PET/CT findings in patients with uterine cervical cancer. In 163 patients with 339 pelvic lymph nodes (LNs) with short-axis diameter >5 mm, the minimum apparent diffusion coefficient (ADC), mean ADC, short- and long-axis diameters, and ratio of long- to short-axis diameters (L/S ratio) were compared in PET/CT-positive and -negative LNs. On PET/CT, 118 (35%) LNs in 58 patients were positive. The mean value of minimum and mean ADCs, short- and long-axis diameters, and L/S ratio were different in PET/CT-positive (0.6436 x 10{sup -3} mm{sup 2}/s, 0.756 x 10{sup -3} mm{sup 2}/s, 10.3 mm, 13.2 mm, 1.32, respectively) and PET/CT-negative LNs (0.8893 x 10{sup -3} mm{sup 2}/s, 1.019 x 10{sup -3} mm{sup 2}/s, 7.4 mm, 11.0 mm, 1.49, respectively) (P<0.05). The Az value of the minimum ADC (0.864) was greater than those of mean ADC (0.836), short-axis diameter (0.764), long-axis diameter (0.640) and L/S ratio (0.652) (P<0.05). The sensitivity and accuracy of the minimum ADC (86%, 82%) were greater than those of the short-axis diameter (55%, 74%), long-axis diameter (73%, 58%) and L/S ratio (52%, 66%) (P<0.05). ADC showed superior correlation with PET/CT compared with conventional size-based criteria on T2WI. (orig.)

    Full Text Available Aim. To describe a new technique of uterine manipulation in laparoscopic management of pelvic cancers. Material and Methods. We used a novel uterine hitch technique in 23 patients from May 2008 to October 2008. These patients underwent pelvic oncologic surgery including laparoscopic radical hysterectomy (n=7, laparoscopic anterior resection (n=4, laparoscopic abdominoperineal resection (n=3, laparoscopic posterior exenteration (n=4, or laparoscopic anterior exenteration (n=5. The uterus was hitched to the anterior abdominal.wall by either a single suture in the fundus or by sutures through the round ligaments. Results. The uterine hitch technique was successfully accomplished in all procedures. It was performed in less than 5 minutes in all cases. It obviated the need for vaginal manipulation. An extra port for retraction could be avoided. There were no intraoperative complications. Conclusion. A practical, cheap and reproducible method for uterine manipulation, during pelvic oncologic surgery is described. It improves the stability of the uterus and also obviates the need for keeping an additional assistant for vaginal manipulation in any of the procedures.

    Progesterone is a key hormonal regulator of the female reproductive system. It plays a major role to prepare the uterus for implantation and in the establishment and maintenance of pregnancy. Actions of progesterone on the uterine tissues (endometrium, myometrium and cervix) are mediated by the combined effects of two progesterone receptor (PR) isoforms, designated PR-A and PR-B. Both receptors function primarily as ligand-activated transcription factors. Progesterone action on the uterine tissues is qualitatively and quantitatively determined by the relative levels and transcriptional activities of PR-A and PR-B. The transcriptional activity of the PR isoforms is affected by specific transcriptional coregulators and by PR post-translational modifications that affect gene promoter targeting. In this context, appropriate temporal and cell-specific expression and function of PR-A and PR-B are critical for normal uterine function. Relevant studies describing the role of PRs in uterine physiology and pathology (endometriosis, uterine leiomyoma, endometrial cancer, cervical cancer and recurrent pregnancy loss) were comprehensively searched using PubMed, Cochrane Library, Web of Science, and Google Scholar and critically reviewed. Progesterone, acting through PR-A and PR-B, regulates the development and function of the endometrium and induces changes in cells essential for implantation and the establishment and maintenance of pregnancy. During pregnancy, progesterone via the PRs promotes myometrial relaxation and cervical closure. Withdrawal of PR-mediated progesterone signaling triggers menstruation and parturition. PR-mediated progesterone signaling is anti-mitogenic in endometrial epithelial cells, and as such, mitigates the tropic effects of estrogen on eutopic normal endometrium, and on ectopic implants in endometriosis. Similarly, ligand-activated PRs function as tumor suppressors in endometrial cancer cells through inhibition of key cellular signaling pathways

    Objective : To explore the expressions of RhoC and ROCK Ⅰ in cervical intraepithelial neoplasia ( CIN ) and cervical cancer as well as their relationship with the genesis of cervical cancer. Methods : The expressions of RhoC and ROCK Ⅰ in cervical cancers( n = 27 ) , CIN Ⅲ( n = 28 ) , CIN Ⅱ ( n = 28 ) , CIN Ⅰ ( n = 25 )and chronic inflammations( n = 28 )were detected by immunohistochemistry. Results : The expressions of RhoC and ROCK Ⅰ in CIN Ⅱ ,CIN Ⅲand cervical cancer were significantly higher than that of CIN Ⅰ and chronic inflammation ( P < 0. 01 ). The severer the cervical lesion was, the higher expression level of Rhoc and ROCK Ⅰ .And the expression level of RhoC was of positive correlation with that of ROCK Ⅰ in CIN Ⅱ and above stages( rs = 0. 605 . P < 0. 001 ).Conclusion: RhoC/ROCK Ⅰ pathway may play an important role in the progression of prec:ancerous lesions of uterine cervix and the genesis of cervical cancer when RhoC expression is at a high level. RhoC/ROCK Ⅰ would be a new target of clinical therapy. RhoC expression may be a good marker for improving treatment scheme and evaluating the risk of canceration.%目的:探讨RhoC和ROCKⅠ基因在不同等级宫颈上皮内瘤变(cervical intraepithelial neoplasia,CIN)和宫颈癌中的表达情况及二者与宫颈癌发生的相关性.方法:采用免疫组化的方法检测慢性炎症28例、CINⅠ25例、CINⅡ28例、CINⅢ28例、宫颈癌27例中RhoC和ROCKⅠ基因的表达情况.结果:RhoC和ROCKⅠ在CINⅡ、CINⅢ和宫颈癌中的表达水平显著高于CINⅠ和慢性炎症,病变程度越重,表达水平越高,差异有统计学意义(P<0.01).RhoC和ROCKⅠ的表达在CINⅡ及以上病变中成正相关(rs=0.605,P<0.001).结论:RhoC在表达水平较高时可能通过ROCKⅠ促进宫颈癌前病变的进展和宫颈癌的发生,RhoC/ROCKⅠ可能成为早期治疗的新靶点.宫颈组织中RhoC的表达水平有助于完善宫颈病变患者的治

  12. Co-operative radical pelvic surgery: a role for the gynecologist in vaginal reconstruction using a uterine myoserosal flap in urological and anorectal cancer surgery.

    This study describes a new technique for reconstructing the vagina and vestibule after radical extirpative surgery for urological and anorectal malignancy. The uterus is always excised when exenterative surgery is performed for gynecological cancer. The use of the uterus as a graft gives the gynecologic oncologist/reconstructive surgeon a role in the multidisciplinary team with urologists when the anterior vaginal wall and vestibule are excised and with the anorectal surgeons when the posterior vaginal wall and perineum are excised for nongynecological cancers. In some such cases, only the anterior or posterior wall of the vagina may be excised, leaving a healthy full-length, one-third, or half-circumference vaginal sleeve. A myoserosal flap is raised from the in situ uterus. The ectocervix is excised, and the adnexa are detached or excised. The uterus is opened to generate a hexagonal flap. The endometrium and endocervix are excised/ablated with electrocautery. The flap is advanced to the edge of the remaining anterior vestibule or reconstituted perineum. The serosal surface of the uterus forms the new wall of the vagina and undergoes metaplastic transformation to squamous epithelium within 3 months. The very satisfactory anatomical and functional outcome means that this technique merits further evaluation.

  13. INTEGRATING CORPUS CONSULTATION IN LANGUAGE STUDIES

    Full Text Available Alongside developments in language research, the potential of corpora as a resource in language learning and teaching has been evident to researchers and teachers since the late 1960s. Despite publications which emphasise the benefits of corpus consultation for language learners (Bernardini, 2002; Kennedy & Miceli, 2001, there is little evidence to suggest that direct corpus consultation is coming to be seen as a complement or alternative to consultation of a dictionary, course book, or grammar by the majority of learners. There is thus a need for research to underpin the integration of corpora and concordancing in the language-learning environment.This study begins with an account of published research relating to course design and structure in the area of corpus consultation by language learners. The focus then narrows to the initial training of learners in corpus consultation, using as an example a course involving undergraduate students on several language degree programmes. The results of the students' consultation of the corpora are examined, including choice of search word(s, analytical skills, the problems encountered, and their evaluation of the activity. The results reveal how corpus consultation can complement traditional language-learning resources, while also raising questions concerning its integration in the language-learning environment.

    Purpose: To investigate pelvic insufficiency fractures (IF) after definitive pelvic radiation therapy for early-stage uterine cervical cancer, by analyzing subjects of a prospective, multi-institutional study. Materials and Methods: Between September 2004 and July 2007, 59 eligible patients were analyzed. The median age was 73 years (range, 37-84 years). The International Federation of Gynecologic Oncology and Obstetrics stages were Ib1 in 35, IIa in 12, and IIb in 12 patients. Patients were treated with the constant method, which consisted of whole-pelvic external-beam radiation therapy of 50 Gy/25 fractions and high-dose-rate intracavitary brachytherapy of 24 Gy/4 fractions without chemotherapy. After radiation therapy the patients were evaluated by both pelvic CT and pelvic MRI at 3, 6, 12, 18, and 24 months. Diagnosis of IF was made when the patients had both CT and MRI findings, neither recurrent tumor lesions nor traumatic histories. The CT findings of IF were defined as fracture lines or sclerotic linear changes in the bones, and MRI findings of IF were defined as signal intensity changes in the bones, both on T1- and T2-weighted images. Results: The median follow-up was 24 months. The 2-year pelvic IF cumulative occurrence rate was 36.9% (21 patients). Using Common Terminology Criteria for Adverse Events version 3.0, grade 1, 2, and 3 IF were seen in 12 (21%), 6 (10%), and 3 patients (5%), respectively. Sixteen patients had multiple fractures, so IF were identified at 44 sites. The pelvic IF were frequently seen at the sacroileal joints (32 sites, 72%). Nine patients complained of pain. All patients' pains were palliated by rest or non-narcotic analgesic drugs. Higher age (>70 years) and low body weight (<50 kg) were thought to be risk factors for pelvic IF (P=.007 and P=.013, Cox hazard test). Conclusions: Cervical cancer patients with higher age and low body weight may be at some risk for the development of pelvic IF after pelvic radiation therapy.

    The aim of the present study was to assess and compare the diagnostic performance of integrated PET/MRI and MRI alone for local tumor evaluation and whole-body tumor staging of primary cervical cancers. In addition, the corresponding impact on further patient management of the two imaging modalities was assessed. A total of 53 consecutive patients with histopathological verification of a primary cervical cancer were prospectively enrolled for a whole-body 18F-FDG PET/MRI examination. Two experienced physicians analyzed the MRI data, in consensus, followed by a second reading session of the PET/MRI datasets. The readers were asked to perform a dedicated TNM staging in accordance with the 7th edition of the AJCC staging manual. Subsequently, the results of MRI and PET/MRI were discussed in a simulated interdisciplinary tumor board and therapeutic decisions based on both imaging modalities were recorded. Results from histopathology and cross-sectional imaging follow-up served as the reference standard. PET/MRI allowed for a correct determination of the T stage in 45/53 (85%) cases, while MRI alone enabled a correct identification of the tumor stage in 46/53 (87%) cases. In 24 of the 53 patients, lymph node metastases were present. For the detection of nodal-positive patients, sensitivity, specificity and accuracy of PET/MRI were 83%, 90% and 87%, respectively. The respective values for MRI alone were 71%, 83% and 77%. In addition, PET/MRI showed higher values for the detection of distant metastases than MRI alone (sensitivity: 87% vs. 67%, specificity: 92% vs. 90%, diagnostic accuracy: 91% vs. 83%). Among the patients with discrepant staging results in the two imaging modalities, PET/MRI enabled correct treatment recommendations for a higher number (n = 9) of patients than MRI alone (n = 3). The present results demonstrate the successful application of integrated PET/MRI imaging for whole-body tumor staging of cervical cancer patients, enabling improved treatment

    The staging of endometrial cancer requires surgery which carries the risk of morbidity. FDG PET/CT combined with anatomical imaging may reduce the number of unnecessary lymphadenectomies by demonstrating the risk of extrapelvic infiltration. The purpose of this study was to optimize FDG PET/CT diagnostic criteria for risk assessment in endometrial cancer after first-line risk triage with MRI. The study population comprised 37 patients who underwent curative surgery for the treatment of endometrial cancer. First, the risk of extrapelvic infiltration was triaged using MRI. Second, multiple glucose metabolic profiles of the primary lesion were assessed with FDG PET/CT, and these were correlated with the histopathological risk of extrapelvic infiltration including lymphovascular space invasion (LVSI) and high-grade malignancy (grades 2 and 3). The results of histological correlation were used to adjust FDG PET/CT diagnostic criteria. Presurgical assessment using MRI was positive for deep (>50 %) myometrial invasion in 17 patients. The optimal FDG PET/CT diagnostic criteria vary depending on the results of MRI. Specifically, SUVmax (≥16.0) was used to indicate LVSI risk with an overall diagnostic accuracy of 88.2 % in patients with MRI findings showing myometrial invasion. High-grade malignancy did not correlate with any of metabolic profiles in this patient group. In the remaining patients without myometrial invasion, lesion glycolysis (LG) or metabolic volume were better indicators of LVSI than SUVmax with the same diagnostic accuracy of 80.0 %. In addition, LG (≥26.9) predicted high-grade malignancy with an accuracy of 72.2 %. Using the optimized cut-off criteria for LVSI, glucose metabolic profiling of primary lesions correctly predicted lymph node metastasis with an accuracy of 73.0 %, which was comparable with the accuracy of visual assessment for lymph node metastasis using MRI and FDG PET/CT. FDG PET/CT diagnostic criteria may need adjustment based on the

    A five-year-old female cat weighing 3 kg was presented by the owner after noticing a large pink, bilobed mass protruding through the vulva during labour. The cat was in good condition, with appropriate lactation, and the newborn kittens were nursing normally. The uterus was not reverted or invaginated at examination, and there was rupture of the mesovarium, mesometrium and uterine-vaginal connection around the cervix. Manual reduction of the prolapsed uterus was not possible because of torn ligaments. A coeliotomy was performed to remove the ovaries, and the apex of the uterine horns was passed by the vaginal route. The remaining part of the mesometrium was disconnected, and the prolapsed uterus was removed. The queen and kittens were discharged from the hospital on the second day after surgery. An unusual feature of this case is that the prolapse was complete, without eversion of any part of the uterus through a vaginal tear.

    While indications of modulated intensity radiation therapy (I.M.R.T.) are perfectly defined in head and neck and prostate cancer patients, this technique remains under evaluation for gynecologic tumours. The implementation of conformal three dimensional radiotherapy in the late 1990 has been the first important step for optimisation of treatment of cervix carcinomas, as it permitted a better target coverage with a significant reduction of the bladder dose. However, this technique often leads to an irradiation of a larger volume of rectum in locally advanced stages and could only spare a limited amount of intestine. I.R.M.T. is one of the optimisation methods potentially efficient for a better sparing of digestive tract during irradiation of cervix carcinomas. The aim of this literature review is to provide the arguments supporting this hypothesis, and to define the place of this technique for dose escalation. (authors)

There are excep- tional difficulties of making the diagnosis of epithelial damages due to the incomplete reproducibility of cytological abnormal ities and the low informative value of a histological study of scrapes from the cervical canal. To avoid hypodiagnosis, it is justifiable to prefer human papillomavirus testing (Hybrid Capture 2 (HC2 to repeat smears for the choice of a management tactic. Conization is recommend ed as a diagnostic and/or therapeutic procedure when the viral load is high in over 35-year-old patients with abnormal smears anda hidden transformation area.

  1. KoralQuery -- A General Corpus Query Protocol

    Bingel, Joachim; Diewald, Nils

    2015-01-01

    The task-oriented and format-driven development of corpus query systems has led to the creation of numerous corpus query languages (QLs) that vary strongly in expressiveness and syntax. This is a severe impediment for the interoperability of corpus analysis systems, which lack a common protocol....... In this paper, we present KoralQuery, a JSON-LD based general corpus query protocol, aiming to be independent of particular QLs, tasks and corpus formats. In addition to describing the system of types and operations that KoralQuery is built on, we exemplify the representation of corpus queries in the serialized...

    Dietary soy intake is associated with protection from breast cancer, but questions persist on the potential risks of the major soy isoflavone genistein (GEN) on female reproductive health. Here, we evaluated intermediate markers of cancer risk in uteri of cycling, young adult Sprague-Dawley rats lifetime exposed to one of three AIN-93G semipurified diets: casein (CAS), soy protein isolate (SPI+ with 276 mg GEN aglycone equivalents/kg) and CAS+GEN (GEN at 250 mg/kg). Postnatal day 50 (PND50) rats lifetime exposed to GEN or SPI+ had similar uterine luminal epithelium height, myometrial thickness, endometrial gland numbers, endometrial immunoreactive proliferating cell nuclear antigen (PCNA), and serum estrogen and progesterone, as CAS-fed rats. GEN-fed rats showed modestly increased apoptosis in uterine glandular epithelium, compared to those of CAS- or SPI+-fed groups. Diet had no effect on the uterine expression of genes for the tumor suppressors PTEN, p53 and p21, and the apoptotic-associated proteins Bcl2, Bax and progesterone receptor. Uterine tissue and serum concentrations of total GEN were higher in rats fed GEN than in those fed SPI+. Human Ishikawa endocarcinoma cells treated with GEN-fed rat serum tended to exhibit increased apoptotic status than those treated with CAS-fed rat serum. Exogenously added GEN (0.2 and 2 microM) increased, while estradiol-17beta (0.1 microM) decreased Ishikawa cell apoptosis, relative to untreated cells. Results suggest that lifetime dietary exposure to soy foods does not alter uterine cell phenotype in young adult rats, while GEN, by enhancing uterine endometrial glandular apoptosis in vivo and in vitro, may confer protection against uterine carcinoma. Given its limited influence on uterine phenotype of young adult females, GEN, when taken as part of soy foods or as supplement, should be favorably considered for other potential health benefits.

  5. Evaluation and management of abnormal uterine bleeding in premenopausal women.

    Sweet, Mary Gayle; Schmidt-Dalton, Tarin A; Weiss, Patrice M; Madsen, Keith P

    2012-01-01

    Up to 14 percent of women experience irregular or excessively heavy menstrual bleeding. This abnormal uterine bleeding generally can be divided into anovulatory and ovulatory patterns. Chronic anovulation can lead to irregular bleeding, prolonged unopposed estrogen stimulation of the endometrium, and increased risk of endometrial cancer. Causes include polycystic ovary syndrome, uncontrolled diabetes mellitus, thyroid dysfunction, hyperprolactinemia, and use of antipsychotics or antiepileptics. Women 35 years or older with recurrent anovulation, women younger than 35 years with risk factors for endometrial cancer, and women with excessive bleeding unresponsive to medical therapy should undergo endometrial biopsy. Treatment with combination oral contraceptives or progestins may regulate menstrual cycles. Histologic findings of hyperplasia without atypia may be treated with cyclic or continuous progestin. Women who have hyperplasia with atypia or adenocarcinoma should be referred to a gynecologist or gynecologic oncologist, respectively. Ovulatory abnormal uterine bleeding, or menorrhagia, may be caused by thyroid dysfunction, coagulation defects (most commonly von Willebrand disease), endometrial polyps, and submucosal fibroids. Transvaginal ultrasonography or saline infusion sonohysterography may be used to evaluate menorrhagia. The levonorgestrel-releasing intrauterine system is an effective treatment for menorrhagia. Oral progesterone for 21 days per month and nonsteroidal anti-inflammatory drugs are also effective. Tranexamic acid is approved by the U.S. Food and Drug Administration for the treatment of ovulatory bleeding, but is expensive. When clear structural causes are identified or medical management is ineffective, polypectomy, fibroidectomy, uterine artery embolization, and endometrial ablation may be considered. Hysterectomy is the most definitive treatment.

  6. Whole Genome Pathway Analysis Identifies an Association of Cadmium Response Gene Loss with Copy Number Variation in Mutant p53 Bearing Uterine Endometrial Carcinomas.

    Directory of Open Access Journals (Sweden)

    Joe Ryan Delaney

    Full Text Available Massive chromosomal aberrations are a signature of advanced cancer, although the factors promoting the pervasive incidence of these copy number alterations (CNAs are poorly understood. Gatekeeper mutations, such as p53, contribute to aneuploidy, yet p53 mutant tumors do not always display CNAs. Uterine Corpus Endometrial Carcinoma (UCEC offers a unique system to begin to evaluate why some cancers acquire high CNAs while others evolve another route to oncogenesis, since about half of p53 mutant UCEC tumors have a relatively flat CNA landscape and half have 20-90% of their genome altered in copy number.We extracted copy number information from 68 UCEC genomes mutant in p53 by the GISTIC2 algorithm. GO term pathway analysis, via GOrilla, was used to identify suppressed pathways. Genes within these pathways were mapped for focal or wide distribution. Deletion hotspots were evaluated for temporal incidence.Multiple pathways contributed to the development of pervasive CNAs, including developmental, metabolic, immunological, cell adhesion and cadmium response pathways. Surprisingly, cadmium response pathway genes are predicted as the earliest loss events within these tumors: in particular, the metallothionein genes involved in heavy metal sequestration. Loss of cadmium response genes were associated with copy number changes and poorer prognosis, contrasting with 'copy number flat' tumors which instead exhibited substantive mutation.Metallothioneins are lost early in the development of high CNA endometrial cancer, providing a potential mechanism and biological rationale for increased incidence of endometrial cancer with cadmium exposure. Developmental and metabolic pathways are altered later in tumor progression.

  8. Corpus-Assisted Creative Writing: Introducing Intermediate Italian Learners to a Corpus as a Reference Resource

    Directory of Open Access Journals (Sweden)

    Claire Kennedy

    2010-02-01

    Full Text Available In much of the literature on the exploitation of corpora for language learning, the learners are viewed as researchers, who formulate and test their own hypotheses about language use. Having identified difficulties encountered in corpus investigations by our intermediate-level students of Italian in a previous study, we have designed a semester-long apprenticeship in corpus use which does not demand of them the high level of language proficiency, attention to detail in observation, and logical rigour that we consider necessary for rewarding work in the learner-as-researcher role. Instead, we introduce a corpus initially as an aid to the imagination in writing, and then to achieving accuracy through specific grammatical problem solving. We see this as the groundwork for subsequent development of the students’ research skills with corpus data. This paper describes the approach we have adopted to the corpus apprenticeship and reports on an evaluation of its effectiveness through case studies of three students and their use of a corpus and bilingual dictionary as reference resources when writing. Drawing on insights from the case studies, we outline a working definition of corpus-consultation literacy for our learning context and identify some refinements to be made to our apprenticeship.

    1995-01-01

    This paper reports on the preliminary phase of our ongoing research towards developing an intelligent tutoring environment for Turkish grammar. One of the components of this environment is a corpus search tool which, among other aspects of the language, will be used to present the learner sample sentences along with their morphological analyses. Following a brief introduction to the Turkish language and its morphology, the paper describes the morphological analysis and ambiguity resolution used to construct the corpus used in the search tool. Finally, implementation issues and details involving the user interface of the tool are discussed.

    From January 1, 1947, through December 31, 1971, 219 patients with primary adenocarcinoma of the intact uterine cervix were treated at the M.D. Anderson Hospital and Tumor Institute. Two modes of therapy were primarily used, namely, irradiationtherapy alone and irradiation therapy plus operation. The 5 year survival resultsare 83.7 per cent for patients with Stage i disease, 48.0 per cent for patients with Stage ii disease, 29.2 per cent for patients with Stage iii disease, and 0.0 per cent for patients with Stage iv disease. The group with irradiation plus operation had a better over-all survival rate. In addition, the incidence of central and pelvic recurrent disease was remarkably lower (fourfold difference). The urologic and bowel complications are discussed. This review lends support for our practice of preoperative irradiation followed by simple (constructive) hysterectomy for selected patients eith adenocarcinoma of the uterine cervix.

    To evaluate the usefulness of 'bridging vascular sign' in the diagnosis of a subserosal/exophytic uterine leiomyoma and the helpfulness of this sign in the differentiation of a uterine leiomyoma from adnexal masses on pelovic magnetic resonance (MR) imaging. Of 20 women with a solitiary pelvic mass in whom pelvic MR imaging was performed during recent three years to differentiate a uterine leiomyoma from an adnexal mass, 12 with surgicopathologically proven subserosal/exophytic uterine leiomymas were included in this study. The other eight women were proved to have tubo-ovarian abscess (n=3D3), ovarian endometrioma (n=3D2), ruptured corpus luteum cyst (n=3D2), and ovarian fibroma (n=3D1). A 1.5 T unit was used to obtain axial/saittal T1- and T2-weighted and gadolinum-enhanced sagittal T1-weighted images. Positive 'bridging vascular sign' was defined through the retrospective review and analysis of MR findings as the presence of intervening curvilinear or tortuous signal-void vascular structures crossing the uterus and the pelvic mass. Using this sign in the diagnosis and differentiation of a uterine leiomyoma from adnexal masses, statistical significance was evaluated. 'Bridging vascular sign' was present in eight of 12 leiomyomas, but no in adnexal masses. Using this sign in the diagnosis and differentiation of a uterine leiomyoma from adnexal masses, sensitivity was 66.7%, specificity 100%, positive predictive value 100%, negative predictive value 66.7%, and accuracy 80%. 'Vascular bridging sign' on MR imaging may be a useful radiologic sign in the diagnosis and differentiation of a subserosal/exophytic uterine leiomyoma from adnexal masses.=20.

    The aim of this pictorial review was to illustrate the normal cervix appearance on T2-weighted images, and give a review of common or less common disorders of the uterine cervix that appear as high signal intensity lesions on T2-weighted sequences. Numerous aetiologies dominated by cervical cancer are reviewed and discussed. This gamut is obviously incomplete; however, radiologists who perform MR women's imaging should perform T2-weighted sequences in the sagittal plane regardless of the indication for pelvic MR. Those sequences will diagnose some previously unknown cervical cancers as well as many other unknown cervical or uterine lesions. (orig.)

    Cervical and endometrial uterine carcinomas are heterogeneous groups of cancers, which are preceded by preneoplastic lesions. More accurate tools are needed to improve the diagnosis and to define markers which may be relevant for the diagnosis, prediction of disease progression and therapeutic response.High throughput technologies for testing and validating molecular targets in cancer lesions and in their precursors are presently available. Among them, the tissue microarray (TMA) presents the advantage of a morphological control of the analyzed tissue fragment. In this article, we review the different aspects of the TMA technology with a special consideration to a uterine carcinogenesis model.

    Full Text Available Carcinosarcoma of the uterus is a rare gynaecological neoplasm, which is also known as malignant mixed mesodermal tumor. Traditionally this tumour has been regarded as a subtype of uterine sarcoma, and its origin remains controversial. The exact nature and prognosis was not clear in the past. It is believed that uterine carcinosarcoma have a Mullerian duct origin and have a capacity to differentiate into various mesenchymal and epithelial components. Regarding the histogensis, various theories have been given; of which ′conversion theory′ was broadly accepted. Carcinosarcoma are mostly of monoclonal origin with the carcinomatous component being the driving force. This type of tumor is broadly divided into two groups, homologous and heterologous, depending on the characteristics of the stroma or mesenchymal components of endometrial tissue. It is more frequent in black women and postmenopausal women. Radiation is a possible etiological factor but the exact etiology is not known yet. However, tamoxifen may induce carcinogenesis in some patients. Its clinical feature is very similar to endometrial carcinoma i.e. postmenopausal vaginal bleeding, have a very aggressive behavior and a poor prognosis. This pelvic malignancy is treated by multimodality therapy including surgery, chemotherapy and radiotherapy. Here we are reviewing old concepts about the disease and modern understandings of the origin, classification, pathogenesis and recent advances in the treatment of the uterine carcinosarcoma.

    We evaluated the role of NM_001024924.1:c.1330+1646C>T (rs13117307) single nucleotide polymorphism (SNP), situated in the intronic region of exocyst complex component 1 (EXCO1), in the development and spreading of cervical squamous cell carcinoma (SCC). Utilizing high resolution melting curve analysis, we analyzed this polymorphism in patients with cervical SCC (n=485) and controls (n=509) in the Polish Caucasian population. Logistic regression analysis was used to adjust for age, parity, oral contraceptive use, tobacco smoking, and menopausal status. The influence of this polymorphism on the expression of EXCO1 was assessed by reverse transcription and real-time quantitative PCR analysis. For all patients with SCC, the p trend value calculated for rs13117307 was statistically significant (ptrend=0.0158). The adjusted odds ratio (OR) for T/T vs. C/C was 1.434 (95 % CI 1.105-1.861, p=0.007). We also found a significant contribution of rs13117307 to tumor stages III, IV and grade of differentiation G3. Other contributors are parity, oral contraceptive use, smoking, and women of postmenopausal age. We observed significant upregulation of EXCO1 transcript levels in the non-cancerous cervical tissues in carriers of the T/T vs. C/C (p=0.016), as well as an increase in the EXCO1 transcript levels in the cervical SCC tissue in carriers of the T/T vs. C/C (p=0.029) and for T/T vs C/T (p=0.0032). The rs13117307 SNP variants may upregulate the transcription of EXCO1, as well as the risk of development and spreading of cervical SCC. Copyright © 2017. Published by Elsevier B.V.

    2014-12-01

    Full Text Available Corpus linguistics has been closely intertwined with digital technology since the introduction of university computer mainframes in the 1960s. Making use of both digitized data in the form of the language corpus and computational methods of analysis involving concordancers and statistics software, corpus linguistics arguably has a place in the digital humanities. Still, it remains obscure and fi gures only sporadically in the literature on the digital humanities. Th is article provides an overview of the main principles of corpus linguistics and the role of computer technology in relation to data and method and also off ers a bird's-eye view of the history of corpus linguistics with a focus on its intimate relationship with digital technology and how digital technology has impacted the very core of corpus linguistics and shaped the identity of the corpus linguist. Ultimately, the article is oriented towards an acknowledgment of corpus linguistics' alignment with the digital humanities.

    2017-09-01

    To determine the true incidence of complete uterine rupture and uterine dehiscence among women delivered by cesarean section after a previous cesarean section. Medical records of all women who delivered at University Hospital in Malmö, Sweden, during 2005-2009 (n = 21 420) were retrieved from the electronic patient record system (EPRS). After adjustment for inaccuracies, 716 women who had undergone repeat cesarean section were identified and their operation reports were reviewed. Descriptions of complete uterine rupture or uterine dehiscence in operation reports were compared with diagnoses registered in EPRS with International Classification of Diseases codes version 10 (ICD-10). Sensitivity and specificity of complete uterine rupture registration were calculated. There were 13 women with a registered diagnosis of uterine rupture. After reviewing medical records of women with repeat cesarean section, seven additional cases of complete uterine rupture, 33 cases of uterine dehiscence and 39 cases of extremely thin myometrium were identified. The incidence of complete uterine rupture and uterine dehiscence for women who delivered by repeat cesarean section was 2.8% and 10.1%, respectively. Diagnosis of complete uterine rupture was underreported in the EPRS by 35% and diagnosis of uterine dehiscence was missing in 100% of cases.

    2009-02-01

    Sufficient uteroplacental blood flow is essential for normal pregnancy outcome and is accomplished by the coordinated growth and remodeling of the entire uterine circulation, as well as the creation of a new fetal vascular organ: the placenta. The process of remodeling involves a number of cellular processes, including hyperplasia and hypertrophy, rearrangement of existing elements, and changes in extracellular matrix. In this review, we provide information on uterine blood flow increases during pregnancy, the influence of placentation type on the distribution of uterine vascular resistance, consideration of the patterns, nature, and extent of maternal uterine vascular remodeling during pregnancy, and what is known about the underlying cellular mechanisms.

    Acute and chronic renal failure secondary to bilateral severe hydroureteronephrosis is a rare sequela of uterine prolapse. We report a case of neglected complete uterine prolapse in a 72-year-old patient resulting in bilateral hydroureter, hydronephrosis, and chronic renal failure. In an attempt to diminish the ureteral obstruction a vaginal pessary was used to reduce the uterine prolapse. Finally, surgical repair of prolapse by means of a vaginal hysterectomy was performed. In conclusion, all patients presenting with complete uterine prolapse should be screened to exclude urinary tract obstruction. If present, obstructive uropathy should be relieved by the reduction or repair of the prolapse before irreversible renal damage occurs.

    Full Text Available The Yale-Classical Archives Corpus (YCAC contains harmonic and rhythmic information for a dataset of Western European Classical art music. This corpus is based on data from classicalarchives.com, a repository of thousands of user-generated MIDI representations of pieces from several periods of Western European music history. The YCAC makes available metadata for each MIDI file, as well as a list of pitch simultaneities ("salami slices" in the MIDI file. Metadata include the piece's composer, the composer's country of origin, date of composition, genre (e.g., symphony, piano sonata, nocturne, etc., instrumentation, meter, and key. The processing step groups the file's pitches into vertical slices each time a pitch is added or subtracted from the texture, recording the slice's offset (measured in the number of quarter notes separating the event from the file's beginning, highest pitch, lowest pitch, prime form, scale-degrees in relation to the global key (as determined by experts, and local key information (as determined by a windowed key-profile analysis. The corpus contains 13,769 MIDI files by 571 composers yielding over 14,051,144 vertical slices. This paper outlines several properties of this corpus, along with a representative study using this dataset.

  4. Uterine epithelial cell proliferation and endometrial hyperplasia: evidence from a mouse model.

    In the uterus, epithelial cell proliferation changes during the estrous cycle and pregnancy. Uncontrolled epithelial cell proliferation results in implantation failure and/or cancer development. Transforming growth factor-β (TGF-β) signaling is a fundamental regulator of diverse biological processes and is indispensable for multiple reproductive functions. However, the in vivo role of TGF-β signaling in uterine epithelial cells remains poorly defined. We have shown that in the uterus, conditional deletion of the Type 1 receptor for TGF-β (Tgfbr1) using anti-Müllerian hormone receptor type 2 (Amhr2) Cre leads to myometrial defects. Here, we describe enhanced epithelial cell proliferation by immunostaining of Ki67 in the uteri of these mice. The aberration culminated in endometrial hyperplasia in aged females. To exclude the potential influence of ovarian steroid hormones, the proliferative status of uterine epithelial cells was assessed following ovariectomy. Increased uterine epithelial cell proliferation was also revealed in ovariectomized Tgfbr1 Amhr2-Cre conditional knockout mice. We further demonstrated that transcript levels for fibroblast growth factor 10 (Fgf10) were markedly up-regulated in Tgfbr1 Amhr2-Cre conditional knockout uteri. Consistently, treatment of primary uterine stromal cells with TGF-β1 significantly reduced Fgf10 mRNA expression. Thus, our findings suggest a potential involvement of TGFBR1-mediated signaling in the regulation of uterine epithelial cell proliferation, and provide genetic evidence supporting the role of uterine epithelial cell proliferation in the pathogenesis of endometrial hyperplasia.

    At present, there is no standard technique that allows surgeons performing total laparoscopic radical hysterectomy to complete the colpotomy and remove an adequate (2-cm) margin of upper vaginal tissue while maintaining adequate pneumoperitoneum. We evaluated the feasibility and safety of using a modified uterine manipulator for total laparoscopic radical hysterectomy in patients with cervical or endometrial cancer. A retrospective review was performed in all patients who underwent total laparoscopic radical hysterectomy using a modified uterine manipulator at our institution during the period April 2004 to December 2006. This analysis included 30 patients who underwent surgery with the modified uterine manipulator. There were no reports of difficulty with placement of the instrument, multiple attempts at placement, difficulty with uterine manipulation, or uterine perforation. In no patient was a vaginal incision or episiotomy required to fit the instrument through the introitus. In no case was there loss of pneumoperitoneum during colpotomy. Additional upper vaginal tissue had to be removed after intraoperative assessment of the adequacy of the surgical specimen in five (16.7%) of 30 patients. Use of the modified uterine manipulator according to our technique is safe and feasible, allowing for adequate vaginal resection and maintenance of pneumoperitoneum.

    2013-04-01

    Full Text Available Problem Statement: Using corpora is still in its infancy in foreign language classes in spite of its great benefits and potential to offer solutions to the various challenges in foreign language instruction both for teachers and learners. This partly stems from a lack of interest and practical knowledge about the pedagogic role that the corpora can play. There is a pressing need to convince teachers of the great benefits of corpora with empirical data.Purpose of Study: This research aims to explore the feasibility of using a corpus to help students differentiate between close synonyms which have similar meanings but cannot be substituted one for the other.Method: This is quasi-experimental research based on a pre and post-test (one shot design design. To this end, participants were introduced to the Corpus of Contemporary American English (COCA and asked to refer to the corpus when deciding the appropriate close synonym in the 50 sentences given. Participants were also interviewed upon completion of the task with the COCA about their use of corpus.Findings and Results: The t-test showed that the use of corpus for deciding on close synonyms proved to be very effective as there was a statistically significant difference in participants‟ performance on the vocabulary portion of the pretest and post-test.Conclusion and Recommendations: The present paper suggests that corpora can be a very rich and effective source of empirical data both for teachers and students to make foreign language learning more meaningful and enjoyable. Providing learners more exposure to authentic examples, corpora can be utilized for pedagogic purposes from syllabus design to materials development. Yet, it needs to be integrated into language courses. Teachersshould be made fully aware of what corpora offer for language teaching.

    Full Text Available Abstract Background Manually annotated corpora are critical for the training and evaluation of automated methods to identify concepts in biomedical text. Results This paper presents the concept annotations of the Colorado Richly Annotated Full-Text (CRAFT Corpus, a collection of 97 full-length, open-access biomedical journal articles that have been annotated both semantically and syntactically to serve as a research resource for the biomedical natural-language-processing (NLP community. CRAFT identifies all mentions of nearly all concepts from nine prominent biomedical ontologies and terminologies: the Cell Type Ontology, the Chemical Entities of Biological Interest ontology, the NCBI Taxonomy, the Protein Ontology, the Sequence Ontology, the entries of the Entrez Gene database, and the three subontologies of the Gene Ontology. The first public release includes the annotations for 67 of the 97 articles, reserving two sets of 15 articles for future text-mining competitions (after which these too will be released. Concept annotations were created based on a single set of guidelines, which has enabled us to achieve consistently high interannotator agreement. Conclusions As the initial 67-article release contains more than 560,000 tokens (and the full set more than 790,000 tokens, our corpus is among the largest gold-standard annotated biomedical corpora. Unlike most others, the journal articles that comprise the corpus are drawn from diverse biomedical disciplines and are marked up in their entirety. Additionally, with a concept-annotation count of nearly 100,000 in the 67-article subset (and more than 140,000 in the full collection, the scale of conceptual markup is also among the largest of comparable corpora. The concept annotations of the CRAFT Corpus have the potential to significantly advance biomedical text mining by providing a high-quality gold standard for NLP systems. The corpus, annotation guidelines, and other associated resources are

    Uterine fibroids are the most common type of benign, gynecologic neoplasm and are the primary indication for performance of a hysterectomy, accounting for >200,000 hysterectomies annually in the USA. At present, females are younger and exhibit larger leiomyomas at the time of diagnosis. Cancer-associated fibroblasts in tumor microenvironments have emerged as an important target for cancer therapy. Repeated stimulation by infectious or non-infectious agents in the uterine tissues, including inflammation, mechanical forces or hypoxia, stimulate the resident fibroblasts to undergo specific activation and, thus, are significant in tumorigenesis. Furthermore, complex signaling pathways regulate the mechanisms of fibroblastic activation. The current review focuses on the molecular mechanisms of fibroblastic activation and the potential association with uterine leiomyoma pathogenesis, enabling an integrated pathogenic analysis for review of the therapeutic options.

    2002-01-01

    In searching of differentially expressed genes in human uterine leiomyomas, differential display was used with twelve pairs of primers to compare human uterine leiomyomas with matched myometrium. False positives were eliminated by reverse Northern analysis. Positives were confirmed by Northern blot analysis.RESULTS: [1] Four of 69 cDNA fragments (3 up-regulated named L1, L2 and L3 and 1 down-regulated named M1 in leiomyoma) were confirmed by Northern analysis. [2] Sequence comparison and Northern analysis proved that L1 is exactly the human ribosomal protein S19. [3] It was present ubiquitously in 13tissues tested but in various levels and even in different size. [4] L1 was highly expressed in parotidean cystadenocarcinoma, pancreatic cancer and breast cancer examined. [5] No mutations have been found in human uterine leiomyomas (n=6). CONCLUSIONS: hRPS19 overexpression might be a universal signal in rapid cell growth tissues.

    Full Text Available Completion of uterine curettage may be challenging following uterine perforation even under sonographic and laparoscopic monitoring. This report illustrates the use of a flexible intubating stylet as a guide to place the suction curette into the uterine cavity when sonography and laparoscopy alone are not successful. Use of a malleable instrument such as an intubating stylet as a guide should be considered an option when insertion of the suction curette into the uterine cavity is complicated by anatomic variation and uterine perforation.

The study aims to known the impact of single versus double layer uterine closure to uterine rupture in the history of cesarean section (CS. In this case report, the clinical question is single versus double-layer uterine closure on the previous CS, gives better outcome to reduce the risk of uterine rupture. To answer this question, we search the evidence from Pub Med and Cochrane database with the keywords: and ldquo;cesarean section" and "uterine rupture" and and ldquo;uterine closure and rdquo;. The inclusion criteria are written in English and focused comparing single and double layer uterine closure to uterine rupture in the previous CS. From the searching literature, we found 3 systematic reviews and 23 articles which were relevant to the topic. After screening the abstract and language, we got 2 systematic reviews and 4 articles. At the end, only 4 articles consisting of 1 systematic review and 3 articles were included to be appraised. Based on evidences, single layer uterine closure did not increase the risk of uterine rupture. Apart from that, shorter operative times and lower estimated blood loss became the superiority of single-layer uterine closure. [Int J Reprod Contracept Obstet Gynecol 2016; 5(7.000: 2074-2078

    Next Generation Sequencing (NGS) is playing a key role in therapeutic decision making for the cancer prognosis and treatment. The NGS technologies are producing a massive amount of sequencing datasets. Often, these datasets are published from the isolated and different sequencing facilities. Consequently, the process of sharing and aggregating multisite sequencing datasets are thwarted by issues such as the need to discover relevant data from different sources, built scalable repositories, the automation of data linkage, the volume of the data, efficient querying mechanism, and information rich intuitive visualisation. We present an approach to link and query different sequencing datasets (TCGA, COSMIC, REACTOME, KEGG and GO) to indicate risks for four cancer types - Ovarian Serous Cystadenocarcinoma (OV), Uterine Corpus Endometrial Carcinoma (UCEC), Uterine Carcinosarcoma (UCS), Cervical Squamous Cell Carcinoma and Endocervical Adenocarcinoma (CESC) - covering the 16 healthy tissue-specific genes from Illumina Human Body Map 2.0. The differentially expressed genes from Illumina Human Body Map 2.0 are analysed together with the gene expressions reported in COSMIC and TCGA repositories leading to the discover of potential biomarkers for a tissue-specific cancer. We analyse the tissue expression of genes, copy number variation (CNV), somatic mutation, and promoter methylation to identify associated pathways and find novel biomarkers. We discovered twenty (20) mutated genes and three (3) potential pathways causing promoter changes in different gynaecological cancer types. We propose a data-interlinked platform called BIOOPENER that glues together heterogeneous cancer and biomedical repositories. The key approach is to find correspondences (or data links) among genetic, cellular and molecular features across isolated cancer datasets giving insight into cancer progression from normal to diseased tissues. The proposed BIOOPENER platform enriches mutations by filling in

  16. Oxytocin modulates the onset of murine parturition by competing ovarian and uterine effects.

    Imamura, T; Luedke, C E; Vogt, S K; Muglia, L J

    2000-09-01

    Recent analysis of mice deficient in both oxytocin (OT) and cyclooxygenase-1 has shown that OT exerts significant effects on both the ovarian corpus luteum and the uterine myometrium during pregnancy. To better define the roles of OT during pregnancy, we evaluated OT action and OT receptor regulation in wild-type and OT-deficient knockout (KO) mice. Continuous infusion of OT revealed that OT can either delay labor at low doses or initiate preterm labor at high doses. The infusion rates of OT necessary for these effects were reduced in OT KO mice. The dose of OT that delayed labor also delayed the normal decrease in plasma progesterone late in gestation, implicating a primary effect on the corpus luteum. Consistent with this hypothesis, luteal OT receptor expression exceeded that of the myometrium until luteolysis occurred. We propose that the downregulation of OT receptors in the corpus luteum and induction of OT receptors in the myometrium serve to shift the predominant consequence of OT action during murine pregnancy from labor inhibition to labor promotion.

    Full Text Available Uterine sarcomas are rare tumours of mesodermal origin. Malignant change occurring in uterine fibroid is termed as leiomyosarcoma. They constitute around 2-6 % uterine malignancies and 25-36% of uterine sarcomas1. The tumour is common in women between the age group 40-50 years. It has an aggressive course and usually metastasis goes to the lungs. The prognosis for women with uterine sarcoma primarily depends on the extent of disease at the time of diagnosis and mitotic index3. Women with tumor size >5 cm in maximum diameter have poor prognosis. These tumours should be diagnosed and managed with no delay and must be followed vigilantly as the rate of recurrence and metastasis is very high.

    2015-01-01

    Corpus Christi Bay and Nueces Bay comprise the middle estuarine portion of Texas’ Coastal Bend region (Figure 1; Burgan and Engle, 2006). Aransas Bay is part of the upper estuarine portion of the region. These bays make up part of the Coastal Bend Bays and Estuaries Program, one of the many estuarine areas in the U.S. Environmental Protection Agency’s National Estuary Program (Holt, 1998). The Coastal Bend region is sub-humid and sub-tropical. Summers are long, hot, and humid, and winters are short and mild. The landscape around the estuaries is dominated by row crops, pastures, and brushy rangeland (Handley and others, 2007). The Nueces River, along with other smaller rivers and creeks, provides freshwater inflow—along with essential nutrients and sediment— into Nueces Bay, which feeds into Corpus Christi Bay (Holt, 1998). Freshwater inflow into the Aransas Bay comes from Mission River, Aransas River, and Copano Creek. The region is relatively dry otherwise and prone to droughts. Corpus Christi receives an average of 76.2 cm (30 in) of rain annually; evaporation usually exceeds 177.8 cm (70 in) (Holt, 1998; Handley and others, 2007). The San Antonio-Nueces Coastal Basin drains into Aransas Bay. The Nueces River basin covers 43,253 km2 (16,700 miles2 ), from northwest of San Antonio, flowing southeast to where it drains into Nueces and Corpus Christi Bays (Holt, 1998).

    We investigated systematic differences in corpus callosum morphology in periventricular nodular heterotopia (PVNH). Differences in corpus callosum mid-sagittal area and subregional area changes were measured using an automated software-based method. Heterotopic gray matter deposits were automatically labeled and compared with corpus callosum changes. The spatial pattern of corpus callosum changes were interpreted in the context of the characteristic anterior-posterior development of the corpus callosum in healthy individuals. Individuals with periventricular nodular heterotopia were imaged at the Melbourne Brain Center or as part of the multi-site Epilepsy Phenome Genome project. Whole brain T1 weighted MRI was acquired in cases (n=48) and controls (n=663). The corpus callosum was segmented on the mid-sagittal plane using the software "yuki". Heterotopic gray matter and intracranial brain volume was measured using Freesurfer. Differences in corpus callosum area and subregional areas were assessed, as well as the relationship between corpus callosum area and heterotopic GM volume. The anterior-posterior distribution of corpus callosum changes and heterotopic GM nodules were quantified using a novel metric and compared with each other. Corpus callosum area was reduced by 14% in PVNH (p=1.59×10(-9)). The magnitude of the effect was least in the genu (7% reduction) and greatest in the isthmus and splenium (26% reduction). Individuals with higher heterotopic GM volume had a smaller corpus callosum. Heterotopic GM volume was highest in posterior brain regions, however there was no linear relationship between the anterior-posterior position of corpus callosum changes and PVNH nodules. Reduced corpus callosum area is strongly associated with PVNH, and is probably associated with abnormal brain development in this neurological disorder. The primarily posterior corpus callosum changes may inform our understanding of the etiology of PVNH. Our results suggest that

  2. Uterine metrology devices for IUD selection.

    Science.gov (United States)

    1981-11-01

    Accurate measurements of the length of the uterine cavity would make it feasible to select an IUD that is compatible with a given cavity size. Considerable evidence exists to indicate that selecting an IUD on the basis of accurate longitudinal measurements of the uterine cavity improves IUD performance. There are study findings to suggest that as more data are available, specific IUDs can be prescribed for defined ranges of uterine cavity length. Metrology (uterine measuring) devices improve the ability of the clinican to measure accurately longitudinal and, in some instances, lateral dimensions of the uterine cavity. Longitudinal measurements depend on identifying the location of the internal os in order to determine the total length of the cervical canal. Lateral metrology devices also provide a measurement of uterine cavity width. Pain and discomfort associated with the use of the prototype lateral measurement instruments developed thus far is a major deterrent to their wide-scale use. 2 metrology devices -- the Crochet Hook Sound and the Hasson Wing Sound -- are designed to obtain longitudinal measurements of total uterine cavity length and of the length of the cervical canel. 2 new instruments -- the Cavimeter and the Hasson Wing Sound 2 -- designed to obtain both lateral and longitudinal measurements are now available for evaluation. The Hasson Wing Sound appears to be the only uterine metrology device available for service programs that could affect continuation rates of IUD users. It can measure the length of the uterine cavity directly, thus permitting improved IUD selection of individual women or the ability to exclude women who should not be IUD users because of small uterine size. An illustration of the prescriptive approach is included in a table.

    1998-01-01

    Resolution of lexical ambiguity, commonly termed ``word sense disambiguation'', is expected to improve the analytical accuracy for tasks which are sensitive to lexical semantics. Such tasks include machine translation, information retrieval, parsing, natural language understanding and lexicography. Reflecting the growth in utilization of machine readable texts, word sense disambiguation techniques have been explored variously in the context of corpus-based approaches. Within one corpus-based framework, that is the similarity-based method, systems use a database, in which example sentences are manually annotated with correct word senses. Given an input, systems search the database for the most similar example to the input. The lexical ambiguity of a word contained in the input is resolved by selecting the sense annotation of the retrieved example. In this research, we apply this method of resolution of verbal polysemy, in which the similarity between two examples is computed as the weighted average of the simi...

    2008-12-01

    Full Text Available Information technologies have now matured to the point of enabling researchers to create a repository of language resources, especially for those languages facing the crisis of endangerment. The development of an online platform of corpora, made possible by recent advances in data storage, character-encoding and web technology, has profound consequences for the accessibility, quantity, quality and interoperability of linguistic field data. This is of particular significance for Formosan languages in Taiwan, many of which are on the verge of extinction. As a response to the recognition of this burgeoning problem, the key objectives of the establishment of the NTU Corpus of Formosan Languages aim to document and thus preserve valuable linguistic data, as well as relevant ethnological and cultural information. This paper will introduce some of the theoretical bases behind this initiative, as well as the procedures, transcription conventions, database normalization, in-house system and three special features in the creation of this corpus.

    1998-01-01

    This paper describes a method for asking statistical questions about a large text corpus. We exemplify the method by addressing the question, "What percentage of Federal Register documents are real documents, of possible interest to a text researcher or analyst?" We estimate an answer to this question by evaluating 200 documents selected from a corpus of 45,820 Federal Register documents. Stratified sampling is used to reduce the sampling uncertainty of the estimate from over 3100 documents to fewer than 1000. The stratification is based on observed characteristics of real documents, while the sampling procedure incorporates a Bayesian version of Neyman allocation. A possible application of the method is to establish baseline statistics used to estimate recall rates for information retrieval systems.

    2011-01-01

    Full Text Available Problem statement: The identification of collocations is very important part in natural language processing applications that require some degree of semantic interpretation such as, machine translation, information retrieval and text summarization. Because of the complexities of Arabic, the collocations undergo some variations such as, morphological, graphical, syntactic variation that constitutes the difficulties of identifying the collocation. Approach: We used the hybrid method for extracting the collocations from Arabic corpus that is based on linguistic information and association measures. Results: This method extracted the bi-gram candidates of Arabic collocation from corpus and evaluated the association measures by using the n-best evaluation method. We reported the precision values for each association measure in each n-best list. Conclusion: The experimental results showed that the log-likelihood ratio is the best association measure that achieved highest precision.

    Full Text Available This article has two main purposes. The first is to provide a short panorama of existing trends within computer-assisted stylistics. The second is to analyse a prize winning novel by English writer Julian Barnes, by resorting to the tenets and working tools of one of the newest branch of Stylistics, the so-called Corpus stylistics. To this end, the article starts by looking at various attempts at defining what style is and their implications to the definition of the discipline known as Stylistics. Then the paper presents recent work within the field of Corpus stylistics, as it describes the uses of computational tools as part of the stylistician tool kit. Finally, the paper provides a variety of ways with which a literary work may be approached digitally with a view to showing how computational tools can aid the stylistician in acts of interpretation.

    Full Text Available English for Specific Purposes (ESP educators often face dilemma in deciding what lexical items to teach their students. In the field of English for Nursing Purposes (ENP, there is no exception on this issue as well. Only by analyzing the nursing corpus made up of essential core textbooks that can provide better insights and guide to both nursing students and educators. This research aims to highlight the 2,000 most frequently used nursing words across the core textbooks of nursing and to profile the types of ‘low frequency’ lexis which comprise the nursing corpus in terms of the General Service List (GSL and Academic Word List (AWL lexis coverage. By knowing the frequently used nursing words would further reduce students’ reading deficiency if the students use the 2000-word list.

    This paper presents an algorithm for selecting an appropriate classifier word for a noun. In Thai language, it frequently happens that there is fluctuation in the choice of classifier for a given concrete noun, both from the point of view of the whole spe ech community and individual speakers. Basically, there is no exect rule for classifier selection. As far as we can do in the rule-based approach is to give a default rule to pick up a corresponding classifier of each noun. Registration of classifier for each noun is limited to the type of unit classifier because other types are open due to the meaning of representation. We propose a corpus-based method (Biber, 1993; Nagao, 1993; Smadja, 1993) which generates Noun Classifier Associations (NCA) to overcome the problems in classifier assignment and semantic construction of noun phrase. The NCA is created statistically from a large corpus and recomposed under concept hierarchy constraints and frequency of occurrences.

    2006-08-01

    Full Text Available Abstract Background The uterus is exposed to changes such as enlargement and distension during pregnancy and labor. In these processes and in the process of cervical ripening, proprioceptive information is likely to be of great importance. Therefore, we wanted to study the possible existence of sensory nerve corpuscles in uterine corpus and cervix during pregnancy and labor. Studies on this aspect have not previously been perfomed. Methods Biopsies were taken from the upper edge of the hysterotomy during caesarean section at term (n = 8, in labor (n = 5 and from the corresponding area in the non-pregnant uterus after hysterectomy (n = 7. Cervical biopsies were obtained transvaginally from the anterior cervical lip. Serial cryostat sections were prepared for immunohistochemistry using polyclonal antibodies against nerve growth factor receptor p75, protein gene product 9.5 and S-100. Results Structures with the characteristics of sensory nerve corpuscles were observed in several specimens after staining for p75, PGP 9.5 and S-100. They were observed in specimens of the non-pregnant corpus and cervix and also in specimens of the pregnant cervix before onset of labor. However, they were absent in all specimens during labor. Conclusion Sensory corpuscles have here for the first time been detected in the human corpus and cervix uteri. Studies on the importance of the corpuscles in relation to the protective reflex actions that occur in the uterus during pregnancy should be performed in the future.

    1977-01-01

    A uterine caliper and sound consisting of an elongated body having outwardly biased resilient caliper wings and a spring-loaded slidable cervical stop. A slide on the body is operatively connected to the wings by a monofilament and operates with respect to a first scale on the body as a width indicator. A rod extending longitudinally on the body is connected to the cervical stop and cooperates with a second scale on the body as a depth indicator. The instrument can be positioned to measure the distance from the outer cervical ostium to the fundus, as read on said second scale. The wings may be allowed to open by moving the slide, and when the wings engage the utero-tubal junctions, the width may be read on said first scale. By adjustment of the caliper wings the instrument may be retracted until the resistance of the inner ostium of the cervix is felt, enabling the length of the cervical canal to be read directly by the position of the longitudinal indicator rod with respect to said second scale. The instrument may be employed to measure the width of the uterine cavity at any position between the inner ostium of the cervix and the fundus.

    AIM: To determine the long-term prevalence of Helicobacter pylori (H pylori) gastritis in patients after partial gastric resection due to peptic ulcer, and to compare the severity of H pylori-positive gastritis in the corpus mucosa between partial gastrectomy patients and matched controls.METHODS: Endoscopic biopsies were obtained from 57 patients after partial gastric resection for histological examination using hematoxylin/eosin and Warthin-Starry staining. Gastritis was graded according to the updated Sydney system. Severity of corpus gastritis was compared between H pylori-positive partial gastrectomy patients and H pylori-positive duodenal ulcer patients matched for age and gender.RESULTS: In partial gastrectomy patients, surgery was performed 20 years (median) prior to evaluation. In 25 patients (43.8%) H pylori was detected histologically in the gastric remnant. Gastric atrophy was more common in H pylori-positive compared to H pylori-negative partial gastrectomy patients (P<0.05). The severity of corpus gastritis was significantly lower in H pylori-positive partial gastrectomy patients compared to duodenal ulcer patients (P<0.01). There were no significant differences in the activity of gastritis, atrophy and intestinal metaplasia between the two groups.CONCLUSION: The long-term prevalence of H pylorigastritis in the gastric corpus of patients who underwent partial gastric resection due to peptic ulcer disease is comparable to the general population. The expression of H pylori gastritis in the gastric remnant does not resemble the gastric cancer phenotype.

    2008-04-01

    Full Text Available In linguistics a corpus typically involves a finite body of texts which are considered to be representative of a particular variety of language at a specific time (McEnery & Wilson, 2001. Those are the assumptions we have had in mind in this metaphor corpus based on business press headlines. Our body of texts is a finite number of headlines drawn from the specific field of the business sections of three newspapers: Financial Times, El País and El Mundo, published over a period running from January to July 2003. Compiling a small corpus of non-literal instantiations as different authors have done (Cortés de los Ríos, 2001; Kövecses, 2002; Charteris-Black, 2003; Koller, 2004; Deignan, 2005; and others will enable us first to identify whether the contextual meaning of a word or a multiword unit of headline contrasts with its basic meaning and whether the contextual meaning can be understood by comparison with that basic meaning, and then to categorize, both in the Spanish and in the British press, the different linguistic realizations of a headline in terms of their syntactic structure, metaphor foci and source domains.

Methods Human uterine cervix cancer cells lines HeLa were used for the current project. Expression,intracellular localization and function of the XIAP in HeLa cells were observed by Laser scanning confocal microscope after transfection. HeLa cells were induced by mifepristone. At the same time,the apoptosis were analyzed for different groups by FCM. Results Expression of DsRed2 - XIAP fusion proteins in HeLa cells were observed in both nucleus and cytoplasm of HeLa cells. HeLa cells which were induced by mifepristone showed partly apoptosis. The DsRed2 - XIAP fusion protein can inhibit apoptosis of HeLa cells by inducing of mifepristone. Conclusion The mifepristone can promote apoptosis of HeLa cells. The DsRed2 - XIAP fusion protein can inhibit apoptosis of HeLa cells by inducing of mifepristone.

    2004-07-01

    Full Text Available Abstract Implantation is a complex spatio-temporal interaction between the growing embryo and the mother, where both players need to be highly synchronized to be able to establish an effective communication to ensure a successful pregnancy. Using our in vivo baboon model we have shown that Chorionic Gonadotropin (CG, as the major trophoblast derived signal, not only rescues the corpus luteum but also modulates the uterine environment in preparation for implantation. This response is characterized by an alteration in both the morphological and biochemical activity in the three major cell types: luminal and glandular epithelium and stromal fibroblasts. Furthermore, CG and factors from the ovary have a synergistic effect on the receptive endometrium. Novel local effects of CG which influence the immune system to permit the survival of the fetal allograft and prevent endometrial cell death are also discussed in this review. An alternate extracellular signal-regulated kinase (ERK activation pathway observed in epithelial endometrial cells and the possibility of differential expression of the CG/LH-R isoforms during gestation, open many questions regarding the mechanism of action of CG and its signal transduction pathway within the primate endometrium.

    2015-06-01

    Full Text Available Myometrial cysts of the uterus are extremely rare. Uterine leiomyomas commonly undergo degenerative changes, which can lead to variable imaging features. Diffuse hydropic change is an unusual form that presents a considerable diagnostic challenge to both radiologists and pathologists. A 27-year old nulliparous patient admitted to our hospital for antenatal care and left sided pelvic pain. Transvaginal ultrasonographic examination revealed a 20 cm intramural cystic lesion in the left region of the corpus uteri suspicious of degenerated myoma. Repeated aspiration was done. Spontaneous abortion occurred in the first trimester. Rapid distension of the abdomen despite repeated aspirations occurred. MRI revealed degenerated myoma. Ultrasound performed one day before surgery revealed a turbid content instead of the clear fluid. Laparotomy was performed revealing a huge interstitial myoma with bloody collection inside so, myomectomy was performed. Histopathology showed hydropic degenerated myoma. Although fibroids usually have a characteristic sonographic appearance, degenerating myomas have variable patterns and can pose a diagnostic dilemma. Extensive cystic degeneration can mimic an ovarian tumour.

    Leiomyomas are the most common benign uterine tumor; however, this entity is relatively uncommon in the pediatric population. Although leiomyomas most commonly present as solitary uterine masses, unusual patterns of growth have been described including diffuse leiomyomatosis. In this condition, the myometrium of the uterus is symmetrically expanded by innumerable confluent leiomyomas; this pattern of growth is quite uncommon and has never been reported in a pediatric patient. This case report illustrates the imaging appearance of diffuse uterine leiomyomatosis in an otherwise healthy 16-year-old girl. (orig.)

    Uterine prolapse is commonly seen in the geriatric age group. Congenital vaginouterine prolapse is a rare condition occurring in neonates and is usually associated with spinal cord malformations in about 85% of cases. Several modalities of treatment have been described for neonatal uterine prolapse. Conservative treatment in the form of simple digital reposition, use of pessary or other self-retaining device is usually sufficient to treat this condition, which is self-limiting and regressive. Here we report our first case of neonatal uterine prolapse, managed successfully with simple digital reposition.

  5. COUP-TFII mediates progesterone regulation of uterine implantation by controlling ER activity.

    Directory of Open Access Journals (Sweden)

    Isao Kurihara

    2007-06-01

    Full Text Available Progesterone and estrogen are critical regulators of uterine receptivity. To facilitate uterine remodeling for embryo attachment, estrogen activity in the uterine epithelia is attenuated by progesterone; however, the molecular mechanism by which this occurs is poorly defined. COUP-TFII (chicken ovalbumin upstream promoter transcription factor II; also known as NR2F2, a member of the nuclear receptor superfamily, is highly expressed in the uterine stroma and its expression is regulated by the progesterone-Indian hedgehog-Patched signaling axis that emanates from the epithelium. To further assess COUP-TFII uterine function, a conditional COUP-TFII knockout mouse was generated. This mutant mouse is infertile due to implantation failure, in which both embryo attachment and uterine decidualization are impaired. Using this animal model, we have identified a novel genetic pathway in which BMP2 lies downstream of COUP-TFII. Epithelial progesterone-induced Indian hedgehog regulates stromal COUP-TFII, which in turn controls BMP2 to allow decidualization to manifest in vivo. Interestingly, enhanced epithelial estrogen activity, which impedes maturation of the receptive uterus, was clearly observed in the absence of stromal-derived COUP-TFII. This finding is consistent with the notion that progesterone exerts its control of implantation through uterine epithelial-stromal cross-talk and reveals that stromal-derived COUP-TFII is an essential mediator of this complex cross-communication pathway. This finding also provides a new signaling paradigm for steroid hormone regulation in female reproductive biology, with attendant implications for furthering our understanding of the molecular mechanisms that underlie dysregulation of hormonal signaling in such human reproductive disorders as endometriosis and endometrial cancer.

  6. How strong is the evidence that solar ultraviolet B and vitamin D reduce the risk of cancer?: An examination using Hill's criteria for causality.

    Science.gov (United States)

    Grant, William B

    2009-01-01

    The ultraviolet-B (UVB)-vitamin D-cancer hypothesis was proposed in 1980. Since then, several ecological and observational studies have examined the hypothesis, in addition to one good randomized, controlled trial. Also, the mechanisms whereby vitamin D reduces the risk of cancer have been elucidated. This report aims to examine the evidence to date with respect to the criteria for causality in a biological system first proposed by Robert Koch and later systematized by A. Bradford Hill. The criteria of most relevance are strength of association, consistency, biological gradient, plausibility/mechanisms and experimental verification. Results for several cancers generally satisfy these criteria. Results for breast and colorectal cancer satisfy the criteria best, but there is also good evidence that other cancers do as well, including bladder, esophageal, gallbladder, gastric, ovarian, rectal, renal and uterine corpus cancer, as well as Hodgkin's and non-Hodgkin's lymphoma. Several cancers have mixed findings with respect to UVB and/or vitamin D, including pancreatic and prostate cancer and melanoma. Even for these, the benefit of vitamin D seems reasonably strong. Although ecological and observational studies are not generally regarded as able to provide convincing evidence of causality, the fact that humanity has always existed with vitamin D from solar UVB irradiance means that there is a wealth of evidence to be harvested using the ecological and observational approaches. Nonetheless, additional randomized, controlled trials are warranted to further examine the link between vitamin D and cancer incidence, survival and mortality.

    To compare uterine and ovarian volumes and uterine artery (UA) Doppler blood flow among women who were treated with antineoplastic regimens when pediatric aged versus healthy controls. Case-control study. Tertiary obstetric and gynecologic center. One hundred twenty-seven women who were treated for childhood cancer with bone marrow transplantation (BMT) and∖or chemotherapy and total body irradiation (TBI) and 64 age-matched healthy controls. Ultrasonographic and clinical evaluations. Uterine and ovarian volume, detection of follicles, and UA pulsatility index (PI). Median uterus and ovarian volumes were reduced by 64% (95% CI, 56.6-70.6) and 83.6% (95% CI, 79.6-86.7), respectively, among cases compared with controls. Median UA PI among cases was increased by 30.3% (95% CI, 19.6-40.8) compared with controls. Ovarian follicles were identified in 24 (18.9%) of 127 cases and 25 (39%) of 64 controls. Uterine volume was reduced after TBI (percent reduction 81.9%; 95% CI, 71.8-87.8) or busulfan (percentage reduction 67.4%; 95% CI, 58.5-75.6) compared with those who had not received a conditioning regimen (percentage reduction 24.4%; 95% CI, 7.6-38.2). The only factors independently associated with reduced uterine and ovarian volumes compared with controls were TBI, busulfan, and BMT.

    Full Text Available Cervical agenesis or dysgenesis is an extremely rare congenital anomaly. Patients with congenital absence of the cervix present with primary amenorrhea and infertility. Though it poses a diagnostic challenge to the clinician, correct diagnosis prior to surgery is possible with the help of ultrasound. Early diagnosis offers significant advantages in patient care and effective presurgical planning. This case report reviews two cases of cervical agenesis diagnosed with the help of ultrasound and later confirmed with the help of MRI. Ultrasonography is the modality of choice to define the internal genital anatomy and helps us to classify the level of obstruction or aplasia in obstructive uterine anomalies.

    Uterine prolapsed is a significant public health problem in Nepal. The study was conducted in 50 women having second and third degree of uterus prolapse who were admitted in Dhulikhel Hospital for vaginal hysterectomy. A total 200 individual were taken as a control groups who were OPD attendants of Dhulikhel hospital without any sign or had no any sign and symptom of uterus prolapse . Data were collected by structured and semi-structured questionnaires and analysis done by using z test. The occurrence of uterus prolapse had significant difference among ethnicity (p value-prolapse were parity, gravida and age at last birth and work after delivery. Therefore civil society and concerned authority should work to raise awareness on the preventive measure of uterus prolapsed.

    Purpose. To evaluate the value of {sup 18}F-fluoro-2-deoxyglucose (F.D.G.) PET-CT and maximal standardized uptake value (SUV{sub max}) of the primary tumor for lymph node staging in cervical cancer. Materials and methods. This retrospective study involved a series of 18 consecutive patients who had benefited from PET-CT and MRI at initial staging for a stage IB or higher cervical carcinoma. The SUV{sub max} of each primary tumor was measured retrospectively. All patients had been previously treated by radio chemotherapy. Lymph node status was obtained in 12 of 18 cases. Results. The sensitivity and specificity for determining lymph node status was 80 and 86%, respectively, for PET-CT, and 80 and 71% for MRI. In 16.6% of cases, PET-CT revealed unknown sus-diaphragmatic lesions. SUV{sub max} of the primary tumor was significantly higher in the N+ than in the N- group (15.6 {+-}1.6 vs 8.5{+-}3.9, p < 0.01). The optimal threshold was determined to be 10.8 from ROC analysis. Conclusion. When staging with F.D.G. PET-CT, SUV{sub max} of a primary cervical cancer seems to be a good predictor of lymph node status. This could lead to an intensification of treatment for patients whose SUV{sub max} is higher than 10.8. A prospective study would allow to assess a potential benefit of treatment intensification for patients with SUV{sub max} higher than 10.8. (authors)

    Full Text Available Isolated skeletal metastasis to the bony calvarium is extremely rare in patients with squamous cell carcinoma of the uterine cervix. We describe the clinical and imaging findings in a case of squamous cell carcinoma of the uterine cervix with metastases tothe bony calvarium as the sole site of metastasis. The patient was a 65-year-old woman with squamous cell carcinoma of the uterine cervix, FIGO stage IIIb, whose initial treatement was chemoradiation therapy. After 22 sessions of external-beam radiation,she developed headaches. On physical examination she had skull bone tenderness. On plain skull X-ray, there were osteolytic bony lesions. Brain MRI showed multiple enhancing skull bone metatstses. Eventually, a whole body bone scintigraphy revealed isolated diffuse increased activity in the bony calvarium. In the literature review, wefound only three similar cases of cervical cancer with scalp metastases and involvement of the bony calvarium.

    The corpus callosum, with its ∼200 million axons, remains enigmatic in its contribution to cognition and behaviour. Agenesis of the corpus callosum is a congenital condition in which the corpus callosum fails to develop; such individuals exhibit localized deficits in non-literal language comprehension, humour, theory of mind and social reasoning. These findings together with parent reports suggest that behavioural and cognitive impairments in subjects with callosal agenesis may overlap with t...

    The prevalence of obstructive uropathy linked to uterine prolapse ranges between 4% and 80%, depending on the series, probably due to the varying degree of severity of the prolapses under consideration. Renal failure or anuria is an unusual complication. Several etiopathogenic theories regarding obstructive uropathy secondary to prolapse have been put forward: ureteral compression by the uterine vessels, severe urethral angulation, ureteral compression against levator ani muscles and the elongation and narrowing of the distal ureter. The major radiological exploration used in studying the urinary tract of these patients is intravenous urography in bipedestation. Emergency treatment for obstructive anuria resulting from a uterine prolapse consists of manually replacement of the prolapse. Surgery is considered to be the definitive ideal treatment, although in the case of surgical or anaesthetic high risk patients, inserting a permanent pessary may constitute a satisfactory solution. We present a case of obstructive anuria resulting from uterine prolapse, which was successfully treated with the insertion of a ring pessary.

    Carcinoma of the uterine cervix and endometrium are common gynecologic malignancies. Both carcinomas are staged and managed by means of the International Federation of Gynecology and Obstetrics (FIGO) staging system. In uterine cervical cancer, the FIGO staging system is determined preoperatively by limited conventional procedures. Although this system is effective for early stage disease, it has inherent inaccuracies in advanced stage diseases and does not address nodal involvement. CT and MR imaging are widely used as comprehensive imaging modalities to evaluate tumor size and extent, and nodal involvement. MR imaging is an excellent modality for depicting invasive cervical carcinoma and can provide objective measurement of tumor volume, and provides high negative predictive value for parametrial invasion and stage IVA disease. In contrast, endometrial cancer is surgically staged. Beside recognition of the important prognostic factors, including histologic subtype and grade, accurate assessment of the tumor extent on preoperative MR imaging is expected to greatly optimize surgical procedure and therapeutic strategy. Contrast-enhanced MR imaging can offer ''one stop'' examination for evaluating the depth of myometrial invasion cervical invasion and nodal metastases. Evaluation of myometrial invasion on MR imaging may be an alternative to gross inspection of the uterus during the surgery. (orig.)

    Taking advantage of vast electronic text resources, the corpus-based approach has contributed a lot to linguistic research. It can be applied to almost all areas of investigations in linguistics (Biber, Conrad and Reppen, 1998) . At the same time the role of corpora in the language classroom remains a great controversy. Some linguists believe that corpora are of great help to the language teachers whereas some others hold a negative view on its application to language teaching. As this argument is still under debate , many language teachers are applying corpora to their own teaching and this is the best way to evaluate the adoption of corpora in language classroom.

    Uterine artery embolisation has been described as successful only when both arteries are embolised. However, results in patients with one congenitally absent or previously ligated artery are unknown. Women suffering from symptomatic uterine myomata were treated at a university teaching hospital, a community hospital and an outpatient surgery centre. Retrospective review of patient response to embolisation was assessed by chart review and questionnaire. Uterine and dominant fibroid size response was assessed by comparing pre- and post-embolisation ultrasound examinations. This study analysed three patient groups within the general population: those who underwent unilateral embolisation because of technical failure, those who ultimately underwent bilateral embolisation after initial technical failure and those who underwent unilateral embolisation because of an absent uterine artery. 12 patients underwent unilateral embolisation, 4 of whom underwent this procedure because of an absent uterine artery. Three of these four patients had a congenitally absent uterine artery arising from the internal iliac artery and all three experienced successful outcomes. The fourth patient had a previously ligated internal iliac artery and her symptoms worsened after the procedure. Eight patients had unilateral embolisation due to technical failure. Five of these patients underwent a subsequent procedure during which the contralateral uterine artery was embolised. Four of these five patients had successful outcomes and one was lost to follow-up. Another of the eight patients suffered an arterial injury leading to technical failure, and was lost to follow-up. Of the two remaining patients with unilateral technical failure, only one had a successful outcome. This study concluded that patients who undergo unilateral embolisation for technical reasons should be offered a second embolisation procedure shortly after the initial procedure. Patients with a congenitally absent uterine artery

    Short Message Service (SMS) messages are largely sent directly from one person to another from their mobile phones. They represent a means of personal communication that is an important communicative artifact in our current digital era. As most existing studies have used private access to SMS corpora, comparative studies using the same raw SMS data has not been possible up to now. We describe our efforts to collect a public SMS corpus to address this problem. We use a battery of methodologies to collect the corpus, paying particular attention to privacy issues to address contributors’ concerns. Our live project collects new SMS message submissions, checks their quality and adds the valid messages, releasing the resultant corpus as XML and as SQL dumps, along with corpus statistics, every month. We opportunistically collect as much metadata about the messages and their sender as possible, so as to enable different types of analyses.

    2011-01-01

    This paper introduces a named entity recognition approach in textual corpus. This Named Entity (NE) can be a named: location, person, organization, date, time, etc., characterized by instances. A NE is found in texts accompanied by contexts: words that are left or right of the NE. The work mainly aims at identifying contexts inducing the NE's nature. As such, The occurrence of the word "President" in a text, means that this word or context may be followed by the name of a president as President "Obama". Likewise, a word preceded by the string "footballer" induces that this is the name of a footballer. NE recognition may be viewed as a classification method, where every word is assigned to a NE class, regarding the context. The aim of this study is then to identify and classify the contexts that are most relevant to recognize a NE, those which are frequently found with the NE. A learning approach using training corpus: web documents, constructed from learning examples is then suggested. Frequency representatio...

    Full Text Available Temporal Expressions in Polish Corpus KPWr This article presents the result of the recent research in the interpretation of Polish expressions that refer to time. These expressions are the source of information when something happens, how often something occurs or how long something lasts. Temporal information, which can be extracted from text automatically, plays significant role in many information extraction systems, such as question answering, discourse analysis, event recognition and many more. We prepared PLIMEX — a broad description of Polish temporal expressions with annotation guidelines, based on the state-of-the-art solutions for English, mainly TimeML specification. We also adapted the solution to capture the local semantics of temporal expressions, called LTIMEX. Temporal description also supports further event identification and extends event description model, focusing at anchoring events in time, ordering events and reasoning about the persistence of events. We prepared the specification, which is designed to address these issues and we annotated all documents in Polish Corpus of Wroclaw University of Technology (KPWr using our annotation guidelines.

    Full Text Available Towards an event annotated corpus of Polish The paper presents a typology of events built on the basis of TimeML specification adapted to Polish language. Some changes were introduced to the definition of the event categories and a motivation for event categorization was formulated. The event annotation task is presented on two levels – ontology level (language independent and text mentions (language dependant. The various types of event mentions in Polish text are discussed. A procedure for annotation of event mentions in Polish texts is presented and evaluated. In the evaluation a randomly selected set of documents from the Corpus of Wrocław University of Technology (called KPWr was annotated by two linguists and the annotator agreement was calculated. The evaluation was done in two iterations. After the first evaluation we revised and improved the annotation procedure. The second evaluation showed a significant improvement of the agreement between annotators. The current work was focused on annotation and categorisation of event mentions in text. The future work will be focused on description of event with a set of attributes, arguments and relations.

The treatment plans of 15 patients have been compared. The clinical target volume (CTV) comprises the gross target volume, the cervix, the upper third of the vagina, and ganglionary areas. The previsional target volume comprises the clinical target volume and a one centimetre margin. Organs at risk are rectum, bladder, intestine and bone marrow. Arc-therapy seems to provide a better sparing of intestine that IMRT, while maintaining a good coverage of the previsional target volume and decreasing treatment duration. Short communication

The Hi varied from 0.052 for RA to 0.163 for 3D-Crt-Fin F (p = 0.009), and the CI between 1.005 and 1.35 (p = 0.26), the S-index from 1.2 to 3.7 (p = 0.001) and the H-index of 1.08 to 1.15 (p = 0.24). All dose limits in risk organs were met with a significant difference in the RA plans versus 3D-Crt-Fin F. In patients with cervical cancer the treatment plans quality with the indices aforementioned seems to be better with the RA technique, being observed a significant reduction of radiation to surrounding organs.
