    Pten is the most frequently mutated gene in uterine endometriod carcinoma (UEC) and its precursor complex atypical hyperplasia (CAH). Because the mutation frequency is similar in CAH and UEC, Pten mutations are thought to occur relatively early in endometrial tumorigenesis. Previous work from our laboratory using the Pten{sup +/-} mouse model has demonstrated somatic inactivation of the wild type allele of Pten in both CAH and UEC. In the present study, we injected adenoviruses expressing Cre into the uterine lumen of adult Pten floxed mice in an attempt to somatically delete both alleles of Pten specifically in the endometrium. Our results demonstrate that biallelic inactivation of Pten results in an increased incidence of carcinoma as compared to the Pten{sup +/-} mouse model. In addition, the carcinomas were more aggressive with extension beyond the uterus into adjacent tissues and were associated with decreased expression of nuclear ER{alpha} as compared to associated CAH. Primary cultures of epithelial and stromal cells were prepared from uteri of Pten floxed mice and Pten was deleted in vitro using Cre expressing adenovirus. Pten deletion was evident in both the epithelial and stromal cells and the treatment of the primary cultures with estrogen had different effects on Akt activation as well as Cyclin D3 expression in the two purified components. This study demonstrates that somatic biallelic inactivation of Pten in endometrial epithelium in vivo results in an increased incidence and aggressiveness of endometrial carcinoma compared to mice carrying a germline deletion of one allele and provides an important in vivo and in vitro model system for understanding the genetic underpinnings of endometrial carcinoma.

    The AIM of this retrospective study is to analyse the indications and the results of treatment of endometrial carcinomas by preoperative radiotherapy. MATERIAL: From 1976 to 1995, 183 patients FIGO stage I or II were treated by preoperative radiotherapy consisting in 95 cases of external radiotherapy (XRT) and brachytherapy (BT) followed by surgery (S) and, in 88 cases of BT alone before surgery, XRT was indicated in cases of grade 2 or 3 and/or cervical involvement. METHODS: XRT was delivered with a 4-fields technique to 40 Gy in 20 fractions with a medial shielding at 30 Gy. BT was done with low dose rate Cs137 and Fletcher-Suit-Delclos applicators with two intra-uterine tubes and vaginal ovoieds. Complications were scored using the French-Italian syllabus. RESULTS: Five-year actuarial survival rates per stage are: Ia=91%, Ib=83%, II=71%, and per grade: G1=80%, G2=79%, G3=90%. Failures were pelvic in 5/183 (2.7%), vaginal in 4 cases (2%) and nodal in 2 cases (1%). Twelve patients developed metastases (6.5%). Complications were analysed during the radiotherapy, after the surgery and with unlimited follow-up. After BT/S, 12 grade 1, 1 grade 2 and 1 grade 3 complications were observed. In the group of patients treated by RT/BT/S, 22 grade 1, 11 grade 2, 4 grade 3 occurred. There is no statistical correlation between complications and parameters of treatment (XRT, hwt, HWT, reference dose to the bladder and rectum, dose rate of brachytherapy). SUMMARY: Preoperative irradiation is an effective and safe treatment of high risk stage I/II endometrial carcinomas. Results seem independent of the pathology grade

    A retrospective analysis was performed of 51 patients with locoregional recurrence of endometrial carcinoma, treated by radiotherapy between 1959 and 1986. There were 17 patients (33%) with isolated vaginal recurrence, 12 patients (24%) with vaginal recurrence with pelvic extension, 7 patients (14%) with pelvic recurrence only, and 15 patients (29%) with simultaneous locoregional and distant failure. Eighty percent of the recurrences occurred within 3.5 years from primary treatment; time to relapse was shorter in patients with advanced-stage, high-grade malignancy at original diagnosis. Locoregional control was achieved in 18 patients (35%). Complete tumor regression in the vagina, irrespective of extravaginal pelvic disease status or distant metastasis, occurred in 28 of 34 patients with vaginal involvement (82%). The 5- and 10-year overall actuarial survivals for all patients were 18 and 12.5%, respectively. The 5- and 10-year progression-free survivals of patients with isolated vaginal recurrences were 40% and 29%, respectively; the 5-year progression-free survival of patients with vaginal recurrence with pelvic extension was 20%. There were no survivors beyond 1.5 years among patients with pelvic recurrence (p = 0.02). All patients with simultaneous locoregional and distant failure were dead by 3.5 years. Stage at original diagnosis, time to relapse from primary treatment, histologic pattern, and grade of malignancy were prognosticators of survival. Five patients (10%) developed a total of ten radiation-related sequelae

    The aim of the present study was to gain more insight into the natural history of endometrial carcinoma, to evaluate prognostic factors and to assess the various treatment methods and the results. Using the data of the Norwegian Radium Hospital, where treatment of gynecological cancer is centralized to a great extent, a large series of patients with long term follow-up, covering all clinical stages and recurrences of endometrial carcinoma, could be evaluated. This resulted in five articles. These articles, together with a study from the University Hospital in Groningen are presented and discussed, and recommendations for treatment are given. The relevant treatments assessed are postoperative external irradiation, preoperative uterine radium packing, preoperative low dose external irradiation and radiotherapy alone. (Auth.)

    Biopsy is the technique of choice for the definitive diagnosis of endometrial carcinoma. Since lymphatic tumor spread has been demonstrated to depend on the degree of myometrial involvement, the definition of the latter with imaging techniques may significantly affect both pfognosis and therapy. We investigated, by means of MR imaging at 0.5 T, 14 patients with endometrial carcinoma, to assess both tumor stage and myometrial involvement. FIGO staging system was employed, and M parameter evaluated (M0= no myometrial involvement; M1involvement confined to the inner third; M2= Involvement confined to the middle third; M3= involvement of the whole myometrium). Another parameter was the characteristic high signal of the tumor on PD and T2W images. The patients were then operated and MR information was correlated with surgical findings. Overall diagnostic accuracy of MR imaging was 85.7% in tumor staging, and 92.2% in defining M parameter. Tumor spread into adnexa and into cervical canal was poorly demonstrated by MR imaging

    Possible deep (more than an inner third of the uterine wall) myometrial invasion and cervical extension of endometrial carcinoma were evaluated prospectively using magnetic resonance (MR) and transabdominal real-time sonography (US) in 20 and 10 patients, respectively. The data obtained from these examinations were compared with hysterosalpingography (HSG) and clinical modalities including hysteroscopy, sounding and histopathologic findings after surgery. The concordance of outlining cervical extension was between MR and hysteroscopy 85 per cent, and between US and hysteroscopy 50 per cent. Deep myometrial tumor invasion was suggested in 4/10 patients by US and in 6/20 by MR, and was confirmed in all but one in each group at histologic examination of the resected uterus. There were no false negative US or MR examinations. Transabdominal US did not prove accurate in defining local endometrial carcinoma (distinguishing between stages I and II), but it may be used as an additional tool in revealing myometrial invasion. MR, however, seems to refine the delineation of uterine tumor growth. (orig.)

    Purpose: This study aimed to evaluate the efficacy of high-dose-rate brachytherapy (HDRB) in the primary treatment of endometrial carcinoma. The results of 12 years of experience (1981-1992) covering 280 patients (mean age 72 years) and their follow-up over 10 years (mean 55 months) are reported. Methods and Materials: Staging was based on clinical examination and fractionated curettage. There were 116 patients in clinical Stage Ia, 119 in Stage Ib, 37 in Stage II, and 8 in Stage III. HDRB was performed four to five times (8.5 Gy) with a one-channel intracavitary applicator and one to two times (7 Gy) with an intravaginal cylinder applicator. Overall and disease-specific survival, local control according to stage and histology, and late side effects were analyzed retrospectively (actuarial method). Results: At 5 years, overall survival, disease-specific survival, and local control were 52.7%, 76.6%, and 75.4% (Stage Ia: 63.9%, 84.9%, and 86.0%; Stage Ib: 47.3%, 73.3%, and 68.8%; and Stage II: 40.2%, 68.6%, and 60.5%) according to histopathologic Grade 1: 65.1%, 83.5%, and 77.7%; for Grade 2: 44.7%, 75.4%, and 75.8%; and for Grade 3: 37.7%, 63.9%, and 74.1%. Eight patients showed progressive disease, 64 developed recurrence after a median of 13 months (45 of whom had a local recurrence only, and 6 of whom had a local recurrence with distant metastases), 6 developed a lymph node recurrence only, and 7 developed distant metastases only. The calculated probability for developing a Grade III late side effect was 5.2% at 5 years. Conclusion: At Stages Ia, Ib, and II in endometrial carcinoma, HDRB is a very effective treatment modality with acceptable local control rates and disease-specific survival for patients who are not fit for surgery. During the time frame of 12 years and in 280 patients the method has proven to have a low risk of acute complications and an acceptable risk of long-term side effects

    Full Text Available Phosphatase and tensin homolog (PTEN is a protein that acts as a tumor suppressor by dephosphorylating the lipid second messenger phosphatidylinositol 3,4,5-trisphosphate. Loss of PTEN function has been implicated in the pathogenesis of a number of different tumors, particularly endometrial carcinoma (ECa. ECa is the most common neoplasia of the female genital tract. Our study evaluates an association between the morphological appearance of endometrial hyperplasia and endometrial carcinoma and the degree of PTEN alterations. A total of 45 endometrial biopsies from Slovak women were included in present study. Formalin-fixed and paraffin-embedded tissue samples with simple hyperplasia (3, complex hyperplasia (5, atypical complex hyperplasia (7, endometrioid carcinomas G1 (20 and G3 (5, and serous carcinoma (5 were evaluated for the presence of mutations in coding regions of PTEN gene, the most frequently mutated tumor suppressor gene in endometrial carcinoma. 75% of the detected mutations were clustered in exons 5 and 8. Out of the 39 mutations detected in 24 cases, 20 were frameshifts and 19 were nonsense, missense, or silent mutations. Some specimens harboured more than one mutation. The results of current study on Slovak women were compared to a previous study performed on Polish population. The two sets of results were similar.

    Endometrial carcinoma is one of the most common gynecologic malignancies and which is predominant in postmenopausal women. Clinically many patients are hospitalized in early stage due to clinical sign and symptom such as vaginal bleeding and in this case, patient's prognosis is known to be good. However, considerable number of patients with advanced and relapsed disease reveal poor prognosis. Therefore, exact staging work up is essential for proper treatment as is primary lesion detection. 18 F-FDG-PET has been widely used for the evaluation of gynecologic malignancies such as cervical carcinoma and ovarian cancer. In contrast, FDG PET application to endometrial carcinoma is limited until now and there is no sufficient data to validate the usefulness of FDG PET for this disease yet. However, several studies showed promising results that FDG PET is sensitive and specific in detection of recurrent or metastatic lesions. Therefore further active investigation in this field can facilitate the use of FDG PET for endometrial carcinoma

    Endometrial carcinoma is the most common gynaecologic malignancy in industrialised countries and the incidence is still rising. Primary treatment is based on preoperative risk classification and consists in most cases of hysterectomy with bilateral salpingo-oophorectomy. In patients with serous and clear cell histology a complete surgical staging is mandatory. However, in routine clinical practice final histology regularly does not correspond with the preoperative histological diagnosis. This results in both over and under treatment. The aim of this multicentre, prospective cohort study is to select a panel of prognostic biomarkers to improve preoperative diagnosis of endometrial carcinoma in order to identify those patients that need extended surgery and/or additional treatment. Additionally, we will determine whether incorporation of cervical cytology and comorbidity could improve this preoperative risk classification. All patients treated for endometrial carcinoma in the participating hospitals from September 2011 till December 2013 are included. Patient characteristics, as well as comorbidity are registered. Patients without preoperative histology, history of hysterectomy and/or endometrial carcinoma or no surgical treatment including hysterectomy are excluded. The preoperative histology and final pathology will be reviewed and compared by expert pathologists. Additional immunohistochemical analysis of IMP3, p53, ER, PR, MLH1, PTEN, beta-catenin, p16, Ki-67, stathmin, ARID1A and L1CAM will be performed. Preoperative histology will be compared with the final pathology results. Follow-up will be at least 24 months to determine risk factors for recurrence and outcome. This study is designed to improve surgical treatment of endometrial carcinoma patients. A total of 432 endometrial carcinoma patients were enrolled between 2011 and 2013. Follow-up will be completed in 2015. Preoperative histology will be evaluated systematically and background endometrium will be

    Purpose: To investigate the incidence and etiologic factors of pelvic fractures following radiation therapy for endometrial carcinoma. Methods and Materials: Tumor registry and radiation oncology records of patients treated for endometrial carcinoma at The Toledo Hospital between April 1989, and December 1992, were reviewed. Patients identified as having pelvic fractures without the presence of metastatic disease underwent total body mineral density measurement with dual x-ray densitometry. Results: Two of 75 patients (2.7%) were found to have pelvic fractures an average of 29 months from the completion of postoperative irradiation. One patient, who received preoperative irradiation, was also identified as having developed a fracture of the pelvis and was included in the analysis. All patients were treated prone with 10-15 MV photons in four fields daily. All three fracture patients received 45 Gy external beam radiation therapy. The two postoperative patients each received a single vaginal brachytherapy application delivering 20 Gy to 0.5 cm deep to the vaginal mucosa with a vaginal cylinder containing 30 mgRaeq 137 Cs. The preoperative patient received a single brachytherapy application with tandem and colpostats delivering 20 Gy to point A. Only one of the three fracture patients had the entire pubis included in the field of external beam treatment. One patient was taking nonsteroidal anti-inflammatory medication, one patient thyroid hormone replacement, and one patient was taking both types of medication. Conclusion: The etiology of pelvic fractures after irradiation is multifactorial. A complete medication history should be obtained, and care should be exercised in positioning the radiation fields to avoid inclusion of the entire pubis prior to the initiation of the radiation treatment

    Undifferentiated endometrial carcinomas are very aggressive high-grade endometrial carcinomas that are frequently under-recognized. This study aimed to analyze the molecular alterations underlying the development of these endometrial carcinomas, focusing on those related to dedifferentiation. We assessed a series of 120 tumors: 57 grade 1 and 2 endometrioid endometrial carcinomas, 15 grade 3 endometrioid endometrial carcinomas, 27 endometrial serous carcinomas, and 21 undifferentiated endometrial carcinomas. We found a high frequency of DNA mismatch repair deficiency (38%) and moderate rate of p53 overexpression (∼33%) in undifferentiated carcinomas. In contrast to the characteristic endometrioid phenotype, there was a dramatic downregulation of E-cadherin expression in the undifferentiated subtype. Quantitative methylation studies dismissed CDH1 promoter hypermethylation as the mechanism responsible for this change in gene expression, while immunohistochemistry revealed that the E-cadherin repressor ZEB1 was frequently overexpressed (62%) in undifferentiated endometrial carcinomas. This finding was accompanied by a sharp downregulation in the expression of the miR-200 family of microRNAs, well-known targets of ZEB1. Furthermore, there was enhanced expression of epithelial-to-mesenchymal transition markers in undifferentiated endometrial carcinomas, such as N-cadherin, cytoplasmic p120, and osteonectin. In addition, HMGA2, a regulator of epithelial-to-mesenchymal transition that is expressed in aggressive endometrial tumors, such as endometrial serous carcinomas and carcinosarcomas, was expressed in >20% of undifferentiated carcinomas. These results suggest that ZEB1 overexpression, associated with E-cadherin and miR-200s downregulation, and the expression of mesenchymal markers might enhance the metastatic potential of undifferentiated endometrial carcinomas, leading to a poor prognosis. In addition, our observations suggest that the immnohistochemical analysis

    Endometrial carcinoma usually occurs in postmenopausal women ; less than 5% occurs in women under the age of 40. Up to one quarter of endometrial carcinoma patients below this age have PCO(polycystic ovary disease, Stein-Leventhal syndrome). The increased incidence of endometrial carcinoma in patients with PCO is related to chronic estrogenic stimulation. We report MR imaging in one case of endometrial carcinoma occuring in a 23 year old woman with PCO and had complained of hypermenorrhea for about three years. On T2-weighted MR image the endometrial cavity was seen to be distended with protruded endometrial masses of intermediate signal intensity, and the junctional zone was disrupted beneath the masses. Both ovaries were best seen on T2-weighted MR imaging and showed multiple small peripheral cysts and low signal-intensity central stroma

    Randomized investigation in two patients groups suffered with endometrial carcinoma (EC) of 1-2 and 3-4 stages (FIGO, 1977) is performed. Effect of blood lymphocytes contrasuppression before and after combined treatment (operation + radiotherapy) is studied as well as delayed therapy results. A part of patients was immunized with tularemia live vaccine (TLV) before treatment. It is shown that the delayed combined treatment results in EC patients correlate with contrasuppression effect revealed in them before therapy. It is concluded that the index of contrasuppression effect revealability and delayed results of combined therapy in EC patients immunized with TLV before therapy have an expressed tendency to improving as compared to nonimmunized patients of the same stages [ru

    Introduction: Postmenopausal bleeding (PMB) is defined as bleeding that occurs after 1 year of amenorrhea in a woman who is not receiving hormone replacement therapy (HRT). About 10% of women with postmenopausal bleeding have a primary or secondary malignancy. Common malignancies among them are endometrial cancer (80%), cervical cancer or an ovarian tumour. Endometrial cancer is the second most common cancer associated with hereditary non-polyposis colorectal cancer. Ninety percent of patients have benign causes. Objective: The objective of this study was to determine the frequency of endometrial carcinoma in patients with post-menopausal bleeding. Study Design: Descriptive case series study. Setting: Department of obstetrics and gynaecology, Lady Willingdon, Lahore. Duration of Study: This study was conducted over a period of six months from January, 1 2009 to June 30, 2009. Subjects and Methods: 50 cases with postmenopausal bleeding. Results: During the period of this study a total number of 50 consecutive patients who met inclusion criteria were enrolled in the study. Ages of the patients who presented with PMB ranged between 48 years and 80 years with a mean age of 59 years. Malignancy was found in 18 out of 50 cases (36%).Cases with endometrial CA were 14 out of 50 cases (28%) and CA cervix constituted 4 out of 50 cases (8%). Benign pathology was more frequent (64%). 13 of 50 cases (26%) had hyperplasia out of which 1 case (2%) was of atypical hyperplasia. Endometrial polyp was found in 4 of 50 cases (8%). 3 of 50 cases (6%) had chronic endometritis. 5 of 50 cases (10%) had chronic cervicitis. While 7 cases (14%) had postmenopausal bleeding due to decubitus ulcer of uterovaginal prolapse. Among malignancies (36%), endometrial cancer is the most frequent malignancy in women with postmenopausal bleeding with mean age of 65 years. Conclusion: In this study it was concluded that the majority of cases of PMB would be expected to be suffering from benign problems

    Objective: To determine the accuracy of Doppler ultrasound in the diagnosis of endometrial carcinoma in patients presenting with post-menopausal bleeding while taking histopathological findings as the gold standard. Methods: The cross-sectional study was done at the Department of Radiology, Bahawal Victoria Hospital, Bahawalpur, from April 1 to September 30, 2009, and comprised 128 patients above 50 years of age having history of post-menopausal bleeding and who were referred to the department. Name, age and hospital registration number were recorded on a proforma. Doppler ultrasound was performed and endometrial thickness and uterine artery resistive index were recorded on transabdominal ultrasonography. Patients with endometrial thickness of more than 5mm and uterine artery resistive index of less than 0.7 were considered to be having endometrial carcinoma. Histopathology findings were also recorded using the hospital registration number of the patient. The findings of Doppler ultrasound scan were validated with the findings of histopathology. Results: Of the 128 patients, 48 (37.5%) were between the ages of 51 and 55 years; 46 (35.93%) were in the 56-60 age group; and 34 (26.57%) were over 65 years. On the basis of Doppler ultrasound findings, 106 (82.8%) patients were diagnosed as having endometrial carcinoma, while 22 (17.19%) were declared negative. Ultrasonography results were compared with histopathology findings. The percentages of true positive, true negative, false positive and false negative were calculated. There were 103 (80.47%) true positive; 12 (9.37%) false positive; 10 (7.81%) true negative; and 3 (2.35%) false negative. Specificity, sensitivity, positive predictive value and negative predictive value were found to be 97.16%, 76%, 89.56% and 76.92% respectively. Conclusion: The use of Doppler ultrasonography in non-invasive diagnosis of endometrial carcinoma in patients presenting with post-menopausal bleeding was quite useful with good

    The sensitivity to estrogen of various growth changes of endometrium and endometrial adenocarcinoma induced experimentally in rats was investigated comparatively by autoradiography using 3 H-estradiol. The results indicated that the rate of 3 H-estradiol uptake showed a parallel relation in non-atypical hyperplasia and atypical type I, II, and III, but in atypical type III, which is considered as a precursor of endometrial carcinoma, there was case where the uptake rate resembled that in atypical type I or II rather than that of endometrial carcinoma. In cases of endometrial carcinoma, there were marked changes in the uptake rate and these changes were different from other endometrial changes. This suggests that deviation from estrogen dependence plays an important role in the onset of endometrial carcinoma. (author)

    Among the clinical parameters that play a pivotal role in predicting the outcome of patients with endometrial carcinoma, intraperitoneal microscopic dissemination represents an important cause of recurrences. To date, peritoneal cytology has been incorporated into the current surgical staging system (International Federation of Gynecology and Obstetrics 88), although its predictive value remains a controversial issue. In this study the authors investigated the possibility of applying immunocytochemistry (ICC) to the diagnosis of peritoneal washing (PW) aimed at improving conventional cytology and verifying the prognostic value of peritoneal malignant cells. The authors analyzed 182 PWs sampled from endometrial cancer patients. The ICC analysis was performed using two monoclonal antibodies (MAbs)--AR-3 and B72.3--that in combination recognize more than 95% of endometrial carcinomas. The presence of peritoneal-free cancer cells was identified morphologically in 27 of 182 lavages (14.8%) and ICC in 50 of 182 (27.5%), with a significant improvement (p <0.0001). Five-year survival analysis, comparing results of ICC and cytodiagnosis, demonstrated a significant decrease of disease-free survival in patients with peritoneal microscopic disease. Furthermore, multivariate analysis showed that ICC diagnosis of PWs is an independent prognostic factor. Data indicate that the use of selected MAbs allows one to identify cytologically false-negative cases, providing results that are highly predictive of a worse clinical outcome.

    Uterine cancer was first subclassified based on anatomic site, separating those tumours arising from the endometrium from cervical cancers. There was then further subclassification of endometrial cancers based on cell type, and this correlated with the Type I and Type II categories identified through the epidemiological studies of Bokhman, with endometrioid carcinoma corresponding (approximately) to Type I and serous carcinoma to Type II. These histotypes are not clearly separable in practice, however, with considerable interobserver variability in histotype diagnosis, especially for high-grade tumours. There followed studies of immunomarkers and then mutational studies of single genes, in attempts to improve subclassification. While these have revealed significant differences in protein expression and mutation profiles between endometrioid and serous carcinomas, there is also considerable overlap, so that there remain challenges in subclassification of endometrial carcinoma. Gene panel testing, using next-generation sequencing, was applied to endometrial cancers and highlighted that there are tumours that show genetic alterations intermediate between classic Type I/endometrioid and Type II/serous carcinomas. The Cancer Genome Atlas studies of endometrioid and serous carcinoma offered revolutionary insight into the subclassification of endometrial carcinoma, i.e. that there are four distinct categories of endometrial carcinoma, rather than two, based on genomic architecture. In this review, we provide an overview of immunohistochemical and molecular markers in endometrial carcinoma and comment on the important future directions in endometrial carcinoma subclassification arising from The Cancer Genome Atlas results.

    Full Text Available Abstract Background Endometrial carcinoma is one of the most common gynecological malignancies in women. The diagnosis of the disease at early or premalignant stages is crucial for the patient's prognosis. To date, diagnosis and follow-up of endometrial carcinoma and hyperplasia require invasive procedures. Therefore, there is considerable demand for the identification of biomarkers to allow non-invasive detection of these conditions. Methods In this study, we performed a quantitative proteomics analysis on serum samples from simple endometrial hyperplasia, complex endometrial hyperplasia, atypical endometrial hyperplasia, and endometrial carcinoma patients, as well as healthy women. Serum samples were first depleted of high-abundance proteins, labeled with isobaric tags (iTRAQ™, and then analyzed via two-dimensional liquid chromatography and tandem mass spectrometry. Protein identification and quantitation information were acquired by comparing the mass spectrometry data against the International Protein Index Database using ProteinPilot software. Bioinformatics annotation of identified proteins was performed by searching against the PANTHER database. Results In total, 74 proteins were identified and quantified in serum samples from endometrial lesion patients and healthy women. Using a 1.6-fold change as the benchmark, 12 proteins showed significantly altered expression levels in at least one disease group compared with healthy women. Among them, 7 proteins were found, for the first time, to be differentially expressed in atypical endometrial hyperplasia. These proteins are orosomucoid 1, haptoglobin, SERPINC 1, alpha-1-antichymotrypsin, apolipoprotein A-IV, inter-alpha-trypsin inhibitor heavy chain H4, and histidine-rich glycoprotein. Conclusions The differentially expressed proteins we discovered in this study may serve as biomarkers in the diagnosis and follow-up of endometrial hyperplasia and endometrial carcinoma.

    Clinical, cytologic, histologic and X-ray procedures were used in examining 120 patients with endometrial carcinoma. The results of pre- and intraoperative determination of clinical stage were compared in 65 cases of uterine extirpation with appendages and lymphadenectomy. Errors in preoperative identification of the extent of tumor expansion were made in 9 cases (13.8+-4.3%). It was found that determinations of the site and expansion of tumor make the case for hysterocervico-angiolymphography whereas identification of tumor pattern and degree of cell differentiation-for cytologic and histologic assays

    Objective: to determine whether endometrial volume or power Doppler indices as measured by 3D ultrasound imaging can discriminate between benign and malignant endometrium in women with postmenopausal bleeding and endometrial thickness > 5 mm. Study design: Eighty-four patients with postmenopausal bleeding and endometrial thickness > 5 mm underwent 3D power Doppler ultrasound examination of the corpus uteri. The endometrial volume was calculated, along with the vascularisation index (VI), flow index and vascularisation flow index (VFI) in the endometrium. The gold standard was the histological diagnosis of the endometrium. Results: There were 56 benign and 28 malignant endometrial. Endometrial thickness and volume were significantly larger in malignant than in benign endometrial, and flow indices in the endometrium were Significantly higher. The area under the ROC curve (AUC) of endometrial thickness was 0.83, that of endometrial volume 0.73, and that of the best power Doppler variable FI 0.93. The best logistic regression model for predicting malignancy contained the variables endometrial thickness and FI. Its AUC was 0.93. Conclusion: the diagnostic performance of endometrial volume measured by 3d imaging with regard to discriminating between benign and malignant endometrium was not superior to that of endometrial thickness measured by 2D ultrasound examination, but 3D power Doppler flow indices are good diagnostic tool in predicting endometrial carcinoma

    To assess the agreement between preoperative endometrial sampling and final diagnosis for tumor grade and subtype in patients with endometrial carcinoma. MEDLINE, EMBASE, ClinicalTrials.gov, and the Cochrane library were searched from inception to January 1, 2017, for studies that compared tumor grade and histologic subtype in preoperative endometrial samples and hysterectomy specimens. In eligible studies, the index test included office endometrial biopsy, hysteroscopic biopsy, or dilatation and curettage; the reference standard was hysterectomy. Outcome measures included tumor grade, histologic subtype, or both. Two independent reviewers assessed the eligibility of the studies. Risk of bias was assessed (Quality Assessment of Diagnostic Accuracy Studies). A total of 45 studies (12,459 patients) met the inclusion criteria. The pooled agreement rate on tumor grade was 0.67 (95% CI 0.60-0.75) and Cohen's κ was 0.45 (95% CI 0.34-0.55). Agreement between hysteroscopic biopsy and final diagnosis was higher (0.89, 95% CI 0.80-0.98) than for dilatation and curettage (0.70, 95% CI 0.60-0.79; P=.02); however, it was not significantly higher than for office endometrial biopsy (0.73, 95% CI 0.60-0.86; P=.08). The lowest agreement rate was found for grade 2 carcinomas (0.61, 95% CI 0.53-0.69). Downgrading was found in 25% and upgrading was found in 21% of the endometrial samples. Agreement on histologic subtypes was 0.95 (95% CI 0.94-0.97) and 0.81 (95% CI 0.69-0.92) for preoperative endometrioid and nonendometrioid carcinomas, respectively. Overall there is only moderate agreement on tumor grade between preoperative endometrial sampling and final diagnosis with the lowest agreement for grade 2 carcinomas.

    Little data exist on the expression of epidermal growth factor receptors (EGF-Rs) in human endometrial cancer. EGF-R status was studied in 65 patients with endometrial carcinomas and in 26 women with nonmalignant postmenopausal endometria, either inactive/atrophic endometrium or adenomatous...... hyperplasia. EGF-R was identified on frozen tissue sections by means of an indirect immunoperoxidase technique with a monoclonal antibody against the external domain of the EGF-R. Seventy-one percent of the carcinomas expressed positive EGF-R immunoreactivity. In general, staining was most prominent...

    Full Text Available The aim of this study was to examine the prevalence and clinicopathological significance of KRAS point mutation in endometrial hyperplasia and carcinoma. We analysed KRAS in 11 cases of complex atypical hyperplasia and in 49 endometrial carcinomas using polymerase chain reaction associated with restriction fragment length polymorphism (PCR-RFPL. Point mutations at codon 12 of KRAS oncogene were identified in 7 of 49 (14,3% tumor specimens and in 2 of 11 (18,2% hyperplasias. No correlation was found between KRAS gene mutation and age at onset, histology, grade of differentiation and clinical stage. We conclude that KRAS mutation is a relatively common event in endometrial carcinogenesis, but with no prognostic value.

    Full Text Available This case report describes the precursor lesion of uterine papillary serous carcinoma (UPSC. A 65-year-old post-menopausal female presented with prolapse and vaginal discharge and underwent a hysterectomy revealing an atrophic endometrium, highly atypical endometrial glands, the lining cells of which showed pseudostratification, hobnailing, a high nuclear to cytoplasmic ratio, and prominent nucleoli. A p53 immunoreactivity score of 8 and a MIB-1 index of 80% was obtained leading to a diagnosis of endometrial intraepithelial carcinoma (EIC. Since serous EIC is commonly associated with extra-uterine serous carcinoma, it is a uniquely aggressive precursor lesion. Molecular studies support the hypothesis that EIC is a precursor of both uterine and extra-uterine invasive serous carcinomas. This is why the treatment protocol for EIC cases is total abdominal hysterectomy (TAH, accompanied by a staging procedure. In our patient, EIC was limited to the endometrium; associated with an excellent clinical outcome.

    The alternative forms of post-operative radiotherapy given in Rotterdam for endometrial carcinoma are described. Patients with infiltration involving less than half the thickness of the myometrium are treated with low dose-rate 137 Cs afterloading techniques. However, in patients with deep infiltration, a combination of high dose-rate Cathetron treatment and external irradiation is used. (U.K.)

    Myometrial invasion (MI) as a percentage (%MI), categorized into <50 or >/=50 %, is an important predictor of prognosis in endometrial carcinoma. Recent studies suggest that tumor-free distance (TFD) to serosa and the absolute depth of invasion (DOI) might be stronger predictors of prognosis.

    To demonstrate the benefits of magnetic resonance imaging (MRI) for the staging of endometrial carcinoma and to compare the results of the spin echo (SE) sequence in T2 with the results of the pos gadolinium intravenous study. We have studied 51 women diagnosed with endometrial carcinoma by means of a D and C and confirmed surgically using T1 equipment. All of them have had SE T1 axial sequences, SE in protonic density (PD) and T'' on an axial and sagittal plane carried out on them and 32 cases were studied after the administration of gadolinium intravenously (i. V.). We have valued the depth of the myometrial infiltration and the cervical invasion. The positive predictive value (PPV) and the negative predictive value (VPV) of the MRI to value the deep infiltration of the endometrium were 87.9% and 77.8% respectively. In the 32 cases where we administered gadolinium we obtained a PPV of 90% and a NPV of 83.8%, in both the SE T2 study and the contrast study. In the diagnosis of the cervical invasion we have obtained PPV and NPV values of 75% and 88.1% respectively. In the group of the 32 cases that had the contrast agent administered, we have obtained the same results in both the series: PPV of 80% and NPV of 85.2%. We have found a high correlation index between the staging using MRI and pathological anatomy, especially in stages I and II of the IFGO (International Federation of Gynecology and Obstretics) classification. The use of gadolinium has not varied the results obtained with the SE T2 series. (Author) 18 refs

    Histologic subclassification of high-grade endometrial carcinomas can sometimes be a diagnostic challenge when based on histomorphology alone. Here we utilized immunohistochemical markers to determine the immunophenotype in histologically ambiguous high-grade endometrial carcinomas that were initially diagnosed as pure or mixed high-grade endometrioid carcinoma, aiming to determine the utility of selected immunohistochemical panel in accurate classification of these distinct tumor types, while correlating these findings with the clinical outcome. A total of 43 high-grade endometrial carcinoma cases initially classified as pure high-grade endometrioid carcinoma (n=32), mixed high-grade endometrioid carcinoma/serous carcinoma (n=9) and mixed high-grade endometrioid carcinoma/clear cell carcinoma (n=2) were retrospectively stained with a panel of immunostains, including antibodies for p53, p16, estrogen receptor, and mammaglobin. Clinical follow-up data were obtained, and stage-to-stage disease outcomes were compared for different tumor types. Based on aberrant staining for p53 and p16, 17/43 (40%) of the high-grade endometrial carcinoma cases initially diagnosed as high-grade endometrioid carcinoma were re-classified as serous carcinoma. All 17 cases showed negative staining for mammaglobin, while estrogen receptor was positive in only 6 (35%) cases. The remaining 26 cases of high-grade endometrioid carcinoma showed wild-type staining for p53 in 25 (96%) cases, patchy staining for p16 in 20 (77%) cases, and were positive for mammaglobin and estrogen receptor in 8 (31%) and 19 (73%) cases, respectively, thus the initial diagnosis of high-grade endometrioid carcinoma was confirmed in these cases. In addition, the patients with re-classified serous carcinoma had advanced clinical stages at diagnosis and poorer overall survival on clinical follow-up compared to that of the remaining 26 high-grade endometrioid carcinoma cases. These results indicate that selected

    Approximately 1 in 20 female cancers in Europe is of the endometrium. Endometrial carcinoma is the most common gynaecologic cancer. Considering the fact that an upward tendency has recently been observed in morbidity due to this type of cancer, this is a serious medical problem. The presented report describes the results of the analysis of selected demographic factors and their effect on the incidence of endometrial cancer. Analysis of the results of treatment of endometrial cancer during 1995-2010 was also an objective of the study. Based on medical records obtained from the HDR Laboratory of Brachytherapy at the Gynaecological & Obstetrics Clinical Hospital, University of Medical Sciences in Poznań, the results of treatment of patients with endometrial cancer by brachytherapy were analyzed. The analysis covered a group of 400 patients. More than a half of the patients completed their education on the level of elementary or secondary school. Taking into consideration the weight of the patients, it appeared that most women had excessive body weight. Most frequently, concomitant hypertension was observed. Moreover, the age at menarche was 12 and 13. Demographic factors exert a significant effect on the incidence of endometrial cancer. 1. Overweight and obesity are important risk factors of endometrial cancer. 2. A strong relationship is observed between the occurrence of hypertension or diabetes, and the development of endometrial cancer. 3. Women who come from the rural environment and continue to live in this environment are more likely to contract endometrial cancer.

    Surgery with staging using FIGO (1988) classification is accepted management for stage III endometrial carcinoma. The delivery of adjuvant therapy is controversial and tends to be individualised. Retrospective review of stage III endometrial carcinoma patients who underwent radical surgery at the Royal Adelaide and Queen Elizabeth Hospitals from 1984 to 2003 was carried out. Medical records were reviewed for details of patient characteristics, surgery, histopathology, adjuvant therapy and recurrence/survival. Sixty-six patients with a median age of 69 (37-97), had a median follow-up of 26 months (1-188 ). For all stage III patients, the actuarial 5-year disease-free and overall survivals were 50 and 43% respectively. Thirty-five patients received pelvic +/- paraaortic radiotherapy, 5 whole abdominal radiotherapy, 14 vaginal brachytherapy boost, 10 chemotherapy and 13 adjuvant hormones. Forty-six percent of patients recurred in a median time of 13 months (0-95). For these patients, the sites of first recurrence were pelvis in 27%, pelvis and abdomen in 23%, abdomen alone in 13%, distant alone in 27%, distant and abdominal in 7% and all three sites in 3%. On univariate analysis disease-free survival was impacted by; age, grade, parametrial involvement, number of extrauterine sites, lymphovascular invasion, adjuvant radiotherapy to the pelvis alone and postoperative macroscopic residual disease. Lymphovascular invasion, post-operative residual disease and adjuvant pelvic radiotherapy remained significant on multivariate analysis. These outcomes for stage III endometrial carcinoma are comparable to the current literature. Ongoing research is required to establish the most appropriate adjuvant therapy in these high risk patients

    A radioimmunoassay was conducted in the pituitary-ovary and pituitary-adrenals systems in 37 cases of endometrial carcinoma treatment and 1, 3, 5 and 14 days after extirpation of the uterus and appendages. The levels of follicle - stimulating (FSH) and luteinizing (LH) hormones of the pituitary, prolactin, ACTH, estradiol, progesterone, testosterone, cortisol and aldosterone were studied. Such disturbances as decreased production of FSH, LH, progesterone and testosterone were observed before operation. Surgery was followed by a considerable rise in prolactin production and basal levels of FSH and LH, a decrease in estradiol, progesterone and testosterone concentrations and was accompanied by a sizeable release of cortisol and aldosterone

  3. Lipocalin 2 Enhances Migration and Resistance against Cisplatin in Endometrial Carcinoma Cells.

    Full Text Available Lipocalin 2 (LCN2 is a secretory protein that is involved in various physiological processes including iron transport. We previously identified LCN2 as an up-regulated gene in endometrial carcinoma, and found that the overexpression of LCN2 and its receptor, SLC22A17, was associated with a poor prognosis. However, the functions and mechanism of action of LCN2 currently remain unclear.The LCN2-overexpressing endometrial carcinoma cell lines, HHUA and RL95-2, and LCN2-low-expressing one, HEC1B, were used. The effects of LCN2 on cell migration, cell viability, and apoptosis under various stresses, including ultraviolet (UV irradiation and cisplatin treatment, were examined using the scratch wound healing assay, WST-1 assay, and Apostrand assay, respectively.LCN2-silencing using shRNA method significantly reduced the migration ability of cells (p<0.05. Cytotoxic stresses significantly decreased the viability of LCN2-silenced cells more than that of control cells. In contrast, LCN2 overexpression was significantly increased cisplatin resistance. These effects were canceled by the addition of the iron chelator, deferoxamine. After UV irradiation, the expression of phosphorylated Akt (pAkt was decreased in LCN2-silenced cells, and the PI3K inhibitor canceled the difference induced in UV sensitivity by LCN2. The cisplatin-induced expression of pAkt was not affected by LCN2; however, the expression of p53 and p21 was increased by LCN2-silencing.These results indicated that LCN2 was involved in the migration and survival of endometrial carcinoma cells under various stresses in an iron-dependent manner. The survival function of LCN2 may be exerted through the PI3K pathway and suppression of the p53-p21 pathway. These functions of LCN2 may increase the malignant potential of endometrial carcinoma cells.

    A nude mouse model for the growth of human endometrial carcinoma and hormonal modulation of the progesterone receptor (PR) was established previously. This study describes the effect of 17 beta-estradiol and tamoxifen (TAM) on growth rate and PR concentration in a hormonally responsive human endometrial tumor (EnCa 101) grown in this experimental system and presents the first characterization of human endometrial carcinoma PR. EnCa 101 was transplanted subcutaneously into ovariectomized, BALB/c, nu/nu athymic mice and grown under 17 beta-estradiol-stimulated, TAM-stimulated, and control conditions. Both 17 beta-estradiol and TAM increased the growth rate of EnCa 101 in nude mice, and a parallel increase in the cytosol PR concentration was observed. PR was partially purified by phosphocellulose and DEAE cellulose chromatography, and the DEAE eluate was analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and photoaffinity labeling with [17 alpha-methyl- 3 H]promegestone ([ 3 H]R5020). Two PR-negative tumors (EnCa K and EnCa V) were also examined in parallel. Photolabeling and sodium dodecyl sulfate-polyacrylamide gel electrophoresis of EnCa 101 grown in the presence of 17 beta-estradiol or TAM revealed incorporation of [3H]R5020 into proteins of molecular weight approximately 116,000 and 85,000. Labeled proteins of molecular weight 66,000, 45,000, and 35,000 were also observed. No incorporation of [ 3 H]R5020 was observed in EnCa 101 grown in the absence of estrogen, nor was any observed in EnCa K or EnCa V

    Between October 1988 and March 1991, 29 patients with endometrial carcinoma had both transvaginal ultrasonography (TVUS) and magnetic resonance imaging (MRI) performed following hysterectomy at the Department of Gynecology and Obstetrics, Okayama University Medical School. The findings were compared with the pathological findings to determine the usefulness of each method. The sensitivity of detecting myometrial invasion was 100% by TVUS and 96% by MRI. The accuracy was 86% by each method. The depth of myometrial invasion was classified into 3 degrees [no myometrial invasion, superficial invasion (≤1/2), deep invasion (>1/2)]. The correct diagnostic rate was 86% by TVUS and MRI. The minimum width and the minimum/maximum width ratio of the intact myometrium obtained by each method in the pathological deep invasion group were significantly lower than those obtained in the other two groups (p<0.01). The sensitivity, the accuracy and the specificity for detecting cervical invasion were 89%, 93% and 95% by both methods. There was no difference between TVUS and MRI for diagnosing myometrial and cervical invasion of endometrial carcinoma. (author)

Our study included 108 patients with endometrial carcinoma and 100 healthy participants. ERCC1 rs11615/XRCC1 rs25487/XPA rs1800975 gene polymorphisms were detected by polymerase chain reaction–restriction fragment length polymorphism. Then the chemotherapy efficacy and toxic effects of the patients were assessed. The genotype and allele frequency of ERCC1 rs11615/XRCC1 rs25487 in the case group were significantly different from that in the control group (all P<0.05. The patients with AA + GA in ERCC1 rs11615 had an increased risk of endometrial carcinoma than those with GG, and the risk of endometrial carcinoma for patients with AA + GA was also higher in comparison with patients with GG genotype in XRCC1 rs25487 (all P<0.05. GG on both ERCC1 rs11615/XRCC1 rs25487 had a higher effective rate of chemotherapy than GA + AA (all P<0.05. ERCC1 rs11615/XRCC1 rs25487 gene polymorphisms were linked with toxic effects in liver, kidney, and nervous system. ERCC1 rs11615/XRCC1 rs25487, muscular invasion, and tumor stage were independent risk factors for the prognosis of endometrial carcinoma (all P<0.05. However, no significant associations were observed between XPA rs1800975 polymorphism and chemotherapy efficacy and prognosis of endometrial carcinoma (all P>0.05. These results indicated that ERCC1 and XRCC1 but not XPA polymorphisms correlate with response to chemotherapy in endometrial carcinoma. Keywords: ERCC1, XRCC1, XPA, single nucleotide

    Screening for DNA mismatch repair (MMR) deficiency in colorectal and endometrial carcinomas identifies patients at risk for Lynch syndrome. Some patients with MMR-deficient tumors have no evidence of a germline mutation and have been described as having Lynch-like syndrome. We compared the clinicopathological features of colorectal and endometrial carcinomas in patients with Lynch-like syndrome and Lynch syndrome. Universal screening identified 356 (10.6%) of 3352 patients with colorectal carcinoma and 72 (33%) of 215 patients with endometrial carcinoma with deficient DNA MMR. Sixty-six patients underwent germline mutation analysis with 45 patients (68%) having evidence of a germline MMR gene mutation confirming Lynch syndrome and 21 patients (32%) having Lynch-like syndrome with no evidence of a germline mutation. Most patients with Lynch-like syndrome had carcinoma involving the right colon compared to patients with Lynch syndrome (93% versus 45%; P Lynch syndrome confirmed by germline mutation analysis. Synchronous or metachronous Lynch syndrome-associated carcinoma was more frequently identified in patients with Lynch syndrome compared to Lynch-like syndrome (38% versus 7%; P = .04). There were no significant differences in clinicopathological variables between patients with Lynch-like syndrome and Lynch syndrome with endometrial carcinoma. In summary, 32% of patients with MMR deficiency concerning Lynch syndrome will have Lynch-like syndrome. Our results demonstrate that patients with Lynch-like syndrome are more likely to have right-sided colorectal carcinoma, less likely to have synchronous or metachronous Lynch syndrome-associated carcinoma, and less likely to demonstrate isolated loss of MSH6 expression within their tumor.

However, the role of HMGB1 in endometrial cancer cell invasion and metastasis remains unexplored. HMGB1 expression was initially assessed by immunohistochemistry and reverse transcription-quantitative polymerase chain reaction (RT-qPCR in normal endometrial tissue and endometrial carcinoma tissue. High expressions of HMGB1 protein were detected in normal endometrial tissues; however, in endometrial cancer tissues, the expressions of HMGB1 were found to be very weak. Furthermore, HMGB1 expressions were negatively correlated with advanced stage and lymph node metastasis in endometrial cancer. Then by RT-qPCR, Western blot and immunocytochemistry, HMGB1 was also detected in primary cultured endometrial cells and four kinds of endometrial cancer cell lines (Ishikawa, HEC-1A, HEC-1B and KLE. We found that the expression of HMGB1 was much higher in normal endometrial cells than in endometrial cancer cells, and reduced expression levels of HMGB1 were observed especially in the highly metastatic cell lines. Using lentivirus transfection, HMGB1 small hairpin RNA was constructed, and this infected the lowly invasive endometrial cancer cell lines, Ishikawa and HEC-1B. HMGB1 knockdown significantly enhanced the proliferation, invasion and metastasis of endometrial cancer cells and induced the process of epithelial-to-mesenchymal transition. These results can contribute to the development of a new potential therapeutic target for endometrial cancer.

    Endometrial stromal sarcoma (ESS) is rare, representing only approximately 0.2% of all uterine malignancies. Mixed type endometrial carcinomas (MT-ECs) are rare tumors with both type I and II features, and are difficult to diagnose. Cases of ESS and MT-ECs coexisting in the same patient are extremely rare. This study aimed to describe a case of ESS in combination with MT-ECs in a 47-year-old premenopausal woman. A woman presented to the hospital complaining of occasional abdominal pain and had high tumor markers: cancer antigen (CA) 19-9 (263.6 U/mL) and CA 125 (428.0 U/mL). Transvaginal ultrasound examination revealed a complex mass (12.3 × 9.1 × 6.3 cm) with solid and cystic components on the right rear wall of the uterus. Abdominopelvic computed tomography images showed a pelvic cystic-solid mixed mass. The patient underwent an exploratory midline laparotomy. The mass was hypothesized to be malignant on the uterine posterior wall. Tumor deposits were found on bilateral parametrium. On peritoneal implantation, multiple metastases were seen on the serosal surface of the bowel and greater omentum. A frozen section revealed a spindle cell sarcoma. Pathological reports following surgery revealed concurrent ESS and MT-ECs. The patient underwent a total abdominal hysterectomy, bilateral salpingo-oophorectomy, total omentectomy, and macroscopic clearance of the tumor. Adjuvant chemotherapy was given. The patient was still alive when this report was written. Considering the rarity of ESS in combination with MT-ECs, this study presented an overview of the literature and discussed a number of histological and clinical issues. Nevertheless, etiology and pathogenesis of these tumors need further investigation.

    tissue, and tissue with endometrial carcinoma of women submitted to surgical treatment (hysterectomy, or between endometrial carcinoma and benign disease, through the PCR technique. METHODS: this is an observational control-case study where 100 women (50 with endometrial carcinoma and 50 with normal endometrial tissue were analyzed for the detection of HPV DNA in samples of endometrial tissue kept in paraffin blocks by the PCR technique. The cases of endometrial carcinoma with uncertain primary site of the lesion as well as the cases with previous or current history of pre-neoplasic lesions or carcinoma of the lower genital tract were excluded. Variables as age, smoking habit, endometrial trophism, squamous differentiation and degree of tumor differentiation were also evaluated. RESULTS: the estimated relative risk of the presence of HPV in the endometrial carcinoma and in the normal endometrial tissue was the same. HPV was detected in 8% of the cases of carcinoma and 10% in the normal endometrial tissue. In spite of HPV having been 3.5 times more detected in women with smoking habit in the group without carcinoma, there was no statistical difference. The presence of HPV was also not correlated with the women's age, endometrial trophism, squamous differentiation and degree of tumor differentiation. The HPV types 16 (5 cases and 18 (4 cases were the viruses most frequently found both in the normal endometrial tissue or in the tissue with carcinoma. No oncogenic low risk virus was detected in the samples. CONCLUSION: The same proportion of HPV is present in the endometrial tissue of women with endometrial cancer and with normal endometrium. It could not be demonstrated a possible correlation of DNA of HPV with the development of endometrial carcinoma.

    To determine whether the relative metabolic activity of pelvic or para-aortic LN compared with that of primary tumor measured by preoperative [{sup 18}F]FDG PET/CT scan has prognostic value in patients with endometrioid endometrial carcinoma. We retrospectively reviewed patients with endometrioid endometrial carcinoma who underwent preoperative [{sup 18}F]FDG PET/CT scans. Prognostic values of PET/CT-derived metabolic variables such as maximum standardized uptake value (SUV) of the primary endometrial carcinoma (SUV{sub Tumor}) and LN (SUV{sub LN}), and the LN-to-endometrial carcinoma SUV ratio (SUV{sub LN} / SUV{sub Tumor}) were assessed. Clinico-pathological data, imaging data, and treatment results were reviewed for 107 eligible patients. Median post-surgical follow-up was 23 months (range, 6-60), and 7 (6.5%) patients experienced recurrence. Regression analysis showed that SUV{sub LN} / SUV{sub Tumor} (P < 0.001), SUV{sub LN} (P = 0.003), International Federation of Gynecology and Obstetrics (FIGO) stage (P = 0.006), and tumor grade (P = 0.011) were risk factors of recurrence. Multivariate regression analysis revealed that FIGO stage (P = 0.034) was the independent risk factor of recurrence. SUV{sub LN} / SUV{sub Tumor} showed significant correlation with FIGO stage (P < 0.001), LN metastasis (P < 0.001), lymphovascular space invasion (P < 0.001), recurrence (P = 0.001), tumor grade (P < 0.001), and deep myometrial invasion of tumor (P = 0.022). Patient groups categorized by SUV{sub LN} / SUV{sub Tumor} showed significant difference in progression-free survival (Log-rank test, P = 0.001). Preoperative SUV{sub LN} / SUV{sub Tumor} measured by [{sup 18}F]FDG PET/CT was significantly associated with recurrence, and may become a novel prognostic factor in patients with endometrioid endometrial carcinoma.

    Full Text Available Abstract Background Microsatellite instability (MSI at tri- or tetranucleotide repeat markers (elevated microsatellite alterations at selected tetranucleotide repeat, EMAST has been recently described. But, the underlying genetic mechanism of EMAST is unclear. This study was to investigate the prevalence of EMAST, in type I endometrial carcinoma, and to determine the correlation between the MSI status and mismatch repair genes (MMR or p53. Methods We examined the 3 mono-, 3 di-, and 6 tetranucleotide repeat markers by PCR in 39 cases of type I endometrial carcinoma and performed the immunohistochemistry of hMSH2, hMLH1, and p53 protein. Results More than two MSI at mono- and dinucleotide repeat markers was noted in 8 cases (MSI-H, 20.5%. MSI, at a tetranucleotide repeat, was detected in 15 cases (EMAST, 38.5%. In remaining 16 cases, any MSI was not observed. (MSS, 42.1%, MSI status was not associated with FIGO stage, grade or depth of invasion. The absence of expression of either one of both hMSH2 or hMLH1 was noted in seven (87.5% of eight MSI-H tumors, one (6.3% of 16 MSS tumors, and five (33.3% of 15 EMAST tumors. (p = 0.010 The expression of p53 protein was found in one (12.5% of eight MSI-H tumors, five (31.3% of 16 MSS tumors, and seven of 15 EMAST tumors. (p = 0.247 Conclusion Our results showed that about 38.5% of type I endometrial carcinomas exhibited EMAST, and that EMAST was rarely associated with alteration of hMSH2 or hMLH1.

    Baby boomers (BB) entering retirement represent a significant burden on medical resources. The unique lifestyle characteristics engendered by the BB may lead to different endometrial cancer characteristics that bear understanding. We sought to characterize BB with endometrioid carcinoma after hysterectomy and compare the results to those of prior to the baby boomers (PB). After reviewing our prospectively maintained database of 1,450 patients with endometrial cancer, we identified 595 patients who underwent hysterectomy for 1988 International Federation of Gynecologic Oncology (FIGO) stage I-II uterine endometrioid carcinomas, who were born between 1926 and 1964. Their medical records were reviewed in this Institutional review board (IRB)-approved study. Patients with non-endometrioid carcinoma and those who received preoperative therapy were excluded. Patients were defined as BB (born 1946-1964) or PB (born in 1926-1945). The two groups were compared regarding patients' demographics, tumor characteristics and survival. Following a univariate analysis, multivariable modeling was carried out using Cox regression analysis. All patients underwent hysterectomy with a minimum of two years' follow-up. There were 234 patients (39%) in the BB group and 361 patients (61%) in the PB group. Median follow-up for the study cohort was 56 months. BB had higher body mass index (p=0.027), lower tumor grade (p=0.002), earlier FIGO stage (p=0.023), higher number of dissected lymph nodes (p=0.008), less lymphvascular space involvement (p=generation.

    Objectives: To determine the associations between serum cancer antigen 15-3 levels and prognostic factors in patients with endometrial carcinomas. Additionally, we investigated the clinical utility of serum cancer antigen 15-3 levels in the selection of low-risk patients with endometrioid type, tumor size <2 cm, myometrial invasion ≤50%, and histological grade 1-2. Methods: Ninety-six patients, who were surgically staged at Ankara Yildirim Beyazit University, Ankara, Turkey, between 2007 and 2016, were retrospectively analyzed. Demographic, clinical, and surgical characteristics were retrieved from the patients’ hospital records. A p<0.05 was considered significant. Results: Fifteen patients had advanced (≥Stage II) disease, 14 patients had Type 2 histology, 20 patients had Grade 3 tumors, 23 patients had lymphovascular space invasion, and 10 patients had positive lymph node involvement. Serum cancer antigen 15-3 levels were significantly higher in patients with advanced (≥Stage II) disease, Type 2 histology, Grade 3 tumors, lymp°hovascular space invasion, and positive lymph node involvement (p<0.05). Serum cancer antigen 15-3 levels were also significantly correlated with tumor size (p=0.006). Serum cancer antigen 15-3 levels were significantly lower (95% confidence interval: 0.57−0.79; p=0.03) in low-risk patients compared to other endometrial carcinoma patients. A cutoff of 25.0 IU/mL was used to identify high-risk patients with a specificity of 100%. Conclusion: Serum cancer antigen 15-3 levels significantly correlated with prognostic factors and were a useful diagnostic tool for endometrial carcinomas. PMID:29114696

    Full Text Available Abstract Background Endometrial cancer is the most common gynecologic malignancy in developed countries. Trop-2 is a glycoprotein involved in cellular signal transduction and is differentially overexpressed relative to normal tissue in a variety of human adenocarcinomas, including endometrioid endometrial carcinomas (EEC. Trop-2 overexpression has been proposed as a marker for biologically aggressive tumor phenotypes. Methods Trop-2 protein expression was quantified using tissue microarrays consisting of formalin-fixed paraffin-embedded specimens from 118 patients who underwent surgical staging from 2001–9 by laparotomy for EEC. Clinicopathologic characteristics including age, stage, grade, lymphovascular space invasion, and medical comorbidities were correlated with immunostaining score. Univariate and multivariate analyses were performed for overall survival, disease-free survival, and progression-free survival in relation to clinical parameters and Trop-2 protein expression. Results Clinical outcome data were available for 103 patients. Strong Trop-2 immunostaining was significantly associated with higher tumor grade (p=0.02 and cervical involvement (p Conclusions Trop-2 protein overexpression is significantly associated with higher tumor grade and serves as an independent prognostic factor for DFS in endometrioid endometrial cancer.

    There is considerable variation within and between cancer centers in the practice of appendectomy as part of cytoreductive surgery for ovarian carcinoma and in the surgical staging of endometrial carcinoma. The purpose of this study was to determine the prevalence and the type of appendiceal pathology, the morbidity associated with appendectomy in gynaecologic cancer surgery. This is a retrospective review of all cytoreductive surgery for ovarian carcinoma and surgical staging for endometrial carcinoma with appendectomy over a four year period. Two hundred and fifty-one patients (38 patients for endometrial carcinoma surgery and 213 patients for ovarian cytoreduction) had an appendectomy performed. Metastases to the appendix was present in 46 (23.2%) of primary ovarian carcinoma and one (2.6%) primary endometrial carcinosarcoma. The appendix was more likely to be involved in advanced stage ovarian cancer with positive peritoneal washings, omental deposits, grade 3 differentiation, and papillary serous histology. Sixteen (6.4%) co-incidental primary appendiceal tumours were detected. No postoperative morbidity specific to appendectomy was identified. One case of ovarian carcinoma was upstaged from IC to IIIA by the appendiceal metastases. There was no upstaging of disease in the endometrial carcinoma group. Appendectomy is an integral part of ovarian cytoreductive surgery but the authors found it did not upstage the disease in a clinically significant manner. The incidence of co-incidental appendiceal primary tumours was high in this series and may add value to the procedure in preventing further surgeries. The absence of procedure related morbidity is reassuring. The authors recommend appendectomy for all ovarian staging surgery and its consideration in type 2 endometrial cancer.

    Minimal uterine serous cancer (MUSC) or serous endometrial intraepithelial carcinoma (EIC) has been described by many different names since 1998. There have been very few cases reported in literature since EIC/MUSC was recognized as a separate entity. The World health Organization (WHO) Classification favors the term serous EIC. Although serous EIC is confined to the uterine endometrium at initial histology diagnosis, a significant number of patients could have distal metastasis at diagnosis, without symptoms. Serous EIC is considered as being the precursor of uterine serous cancer (USC), but pure serous EIC also has an aggressive behavior similar to USC. It is therefore prudent to have an accurate diagnosis and appropriate surgical staging. There are very few published articles in literature that discuss the pure form of serous EIC. The aim of this series is to share our experience and review evidence for optimum management of serous EIC. We report a series of five women treated in our institute in the last 3 years. We reviewed the relevant literature on serous EIC and various management strategies, to recommend best clinical practice. Pure serous EIC is a difficult histopathological diagnosis, which requires ancillary immunohistochemical staining. It can have an aggressive clinical behavior with early recurrence and poor survival. Optimum surgical staging, with appropriate adjuvant treatment, should be discussed when treating these patients

    To assess the diagnostic accuracy of magnetic resonance imaging in local staging of endometrial carcinoma, and to review the results and pitfalls described in the literature. Thirty women with a histological diagnosis of endometrial carcinoma underwent magnetic resonance imaging. Unenhanced T2-weighted and dynamic contrast-enhanced Ti-weighted sequences were obtained. Hysterectomy and salpingo-oophorectomy was performed in all patients. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy were calculated for the detection of deep myometrial and cervical infiltration. For deep myometrial infiltration T2-weighted sequences reached a sensitivity of 85%, specificity of 76%, PPV of 73%, NVP of 87%, and accuracy of 80%, while contrast-enhanced scans reached a sensitivity of 90%, specificity of 80%, PPV of 82%, NPV of 89%, and accuracy of 85%. For cervical infiltration T2-weighted sequences reached a sensitivity of 75%, specificity of 88%, PPV of 50%, NPV of 96%, and accuracy of 87%, while contrast-enhanced scans reached a sensitivity of 100%, specificity of 94%, PPV of 75%, NPV of 100%, and accuracy of 95%. Unenhanced and dynamic gadolinium-enhanced magnetic resonance allows accurate assessment of myometrial and cervical infiltration. Information provided by magnetic resonance imaging can define prognosis and management.

    We present the case of a 44-year-old nulliparous woman who experienced irregular menstrual cycles for about 10 years and developed both pituitary prolactinoma and endometrioid endometrial carcinoma. In premenopausal women, hyperprolactinemia causes hypogonadism by inhibiting secretion of gonadotropin-releasing hormone and thus suppressing luteinizing hormone levels, which can cause menstrual disorders ranging from amenorrhea, oligomenorrhea and chronic anovulatory cycle to short luteal phase of the menstrual cycle. A chronic anovulatory menstrual cycle is the most common cause of long-term exposure of the endometrium to endogenous estrogen without adequate opposition from progestins, which can lead to endometrioid endometrial carcinoma. In this case, pituitary prolactinoma may have caused the chronic anovulatory cycle and indirectly led to the endometrioid endometrial carcinoma. In patients for whom the cause of irregular menstruation and chronic anovulatory cycle is suspected to be hyperprolactinemia, explorations of both the hypophysis and endometrium are essential.

    Objective: To determine the diagnostic accuracy of Diffusion-Weighted Magnetic Resonance Imaging (DWMRI) in the detection of myometrial invasion in endometrial cancer taking histopathology as gold standard. Study Design: Cross-sectional validation study. Place and Duration of Study: Department of Radiology, The Aga Khan University Hospital, Karachi, from January to December 2012. Methodology: DWMRI (b-value = 50,400 and 800 s/mm2) was performed in 85 patients of biopsy-proven endometrial carcinoma before hysterectomy using body and spine coil at 1.5 Tesla. DWI was evaluated for presence of myometrial invasion by tumor with histopathology as gold standard. Sensitivity, specificity, the negative predictive value and positive predictive value and accuracy of DWI were assessed against the gold standard. Results: On DWI, superficial myometrial invasion was found in 42 patients and deep myometrial invasion in 43. On histopathology, superficial myometrial invasion was found in 53 patients and deep myometrial invasion in 32. Hence sensitivity, specificity, positive predictive value, negative predictive value and accuracy for the assessment of myometrial invasion by endometrial tumor on DW images was 90 percentage, 73 percentage, 67 percentage, 92 percentage and 80 percentage, respectively. Diagnostic accuracy of diffusion-weighted magnetic resonance imaging in detection of myometrial invasion in endometrial cancer was 80 percentage. Conclusion: DWI is highly accurate in assessing myometrial invasion and can be used as an adjunct to routine MRI for pre-operative evaluation of myometrial invasion of endometrial cancer. (author)

    Purpose Lipocalin 2 (LCN2) is a secretory protein that is involved in various physiological processes including iron transport. We previously identified LCN2 as an up-regulated gene in endometrial carcinoma, and found that the overexpression of LCN2 and its receptor, SLC22A17, was associated with a poor prognosis. However, the functions and mechanism of action of LCN2 currently remain unclear. Methods The LCN2-overexpressing endometrial carcinoma cell lines, HHUA and RL95-2, and LCN2-low-expr...

    The results of a immunomorphologic comprehensive study of epithelial-stromal relationships in the uterus hyperplasia and endometrial cancer suggest that the suppressor gene of cancer (PTEN) plays a key role in the process of neoplastic transformation of endometrial hyperplasia and adenocarcinoma development. For the first time the existence of two highly differentiated endometrial adenocarcinoma immunophenotype were detected The first one is a PTEN-negative endometrial aedenocarcinoma, characterized by an almost complete inhibition of tumor suppressor gene PTEN in the epithelium of the glands and stromal cell of the tumor The second type is a PTEN-positive endometrial adenocarcinoma, in which epithelial and stromal tumor suppressor gene PTEN activity has retained Based on these results we have formulated a hypothesis about the different types of endometrial hyperplasia morphogenesis and its possible transfer to cervical cancer associated with features of tumor suppressor gene PTEN.

    The study was to assess the usefulness of T2-weighted and enhanced T1-weighted MR images in differentiating endometrial adenocarcinoma and hyperplasia. The subjects were 21 patients with endometrial hyperplasia (Group A), consisting of 15 with cystic glandular hyperplasia and 6 with atypical hyperplasia, and 7 with endometrial adenocarcinoma (Group B). Six other patients with no evidence of abnormal endometrial findings served as controls. In Group A, the endometrium had a high signal intensity on T2-weighted images, and was 10 mm or over in thickness before menopause and 6 mm after menopause. It was also a high or intermediate signal intensity on enhanced T1-weighted images. In patiemts with cystic glandular hyperplasia, the junctional zone was 10 mm or over on T2-weighted images. Similar findings were seen on enhanced T1-weighted images. In patients with atypical hyperplasia, the junctional zone disappeared or decreased on enhanced images compared with those on T2-weighted images. In group B, the endometrium had an intermediate or high signal intensity on T2-weighted images, with the junctional zone being 10 mm or more. Enhanced T1-weighted images showed lower signal intensities in the tumorous area than in the normal endometrium and muscular layer. These findings indicated that enhanced MR imaging may be useful in diagnosing endometrial lesions. (N.K.).

    The purpose of this study was to investigate the usefulness of multislice dynamic MR imaging with Turbo FLASH in assessing myometrial invasion by endometrial carcinoma. Dynamic MR imaging was performed with bolus injection of Gd-DTPA and with 1.5-T Siemens Magnetom imager using Turbo FLASH. Thirty-six endometrial carcinomas were evaluated with pathologic correlation. Junctional zone showed more rapid contrast enhancement effects than myometrium even after menopause. Contrast to noise ratio between junctional zone and endometrial carcinoma was the highest about fifty seconds after bolus injection. Only at that time could the degree of invasion to junctional zone in post-menopausal women whose junctional zones could not be seen on T{sub 2}-weighted images or contrast-enhanced T{sub 1}-weighted images be evaluated correctly. The accuracy in assessing myometrial invasion with T{sub 2}-weighted images, postcontrast T{sub 1}-weighted images, and dynamic MR imaging was 75%, 81% and 89% respectively. Though there was no statistically significant difference, multislice dynamic imaging with Turbo FLASH technique is considered to be a useful imaging method for the pre-operative assessment of myometrial invasion by endometrial carcinoma.

    Purpose: The aggressiveness of radiation therapy for patients with medically inoperable endometrial carcinoma is controversial. Patients may die of their underlining medical disease before succumbing to cancer. We try to identify certain subgroup of patients who might benefit most from an aggressive approach and also investigate the impact of residual tumor present in dilatation and curettage (D and C) specimen obtained in second intracavitary implant (ICI). Methods and Materials: From 1965 to 1990, 101 patients were treated for clinical clinical Stage I endometrial carcinoma with RT alone due to medical problems. Ages ranged from 39 to 94 years (median 71 years). There were 18 patients with clinical Stage IA and 83 with clinical Stage IB disease. Histology included 44 well-differentiated, 37 moderately differentiated, and 20 poorly differentiated tumors. Radiation therapy consisted of external beam only in 3 patients, ICI alone in 26, whole pelvis plus ICI in 10, and whole pelvis plus split field plus ICI in 62. A second D and C was performed on 26 patients at the time of the second ICI. Minimum follow-up was 2 years (median, 6.3 years). Results: The 5-year actuarial disease-free survival (DFS) for the studied cohort is comparable to the expected survival of an age-matched population. Pelvic control was 100% for Stage IA and 88% for Stage IB with 5-year disease-free survivals of 80 and 84%, respectively. We also observed a greater disassociation of DFS and overall survival among patients older than 75 years (84 and 55%, respectively) than in younger patients (84 and 78%, respectively). This is mainly because older patients succumbed to their medical illness. Well-differentiated disease demonstrated the trend toward a better outcome than moderately or poorly differentiated lesions in Stage IB patients (p 0.05), but not in Stage IA patients. Aggressive radiation therapy approach showed the trend toward a better result in Stage IB patients 75 years of age or younger

    Although the main treatment of endometrial cancer is surgery, the gross spread of carcinoma in pelvis, elderly age of the patients and serious therapeutical diseases do not allow to operate 20% of the patients. For these patients only radical treatment decision is the combined radiation therapy. However, using various modalities of combined radiotherapy, the treatment results are not satisfying: only 52% of patients survive 5 years. There was implemented a new method of combined radiotherapy, using a three-channel applicator with two-positional locating of HDR Co-60 radioactive sources (group I). A new method of brachytherapy for endometrial carcinoma using a HDR Cf 252 sources (group II) was implemented too. For group I the medium total dose of the point A was 77.6 Gy, point I - 69.6 Gy. point 2 - 84.2 Gy, point B - 52.6 Gy, For group II the medium total dose the points A, 3 and 4 was 50 iGy. For group I 1 year overaII survival rate was 85%, 3 year - 73%. The 3 year survival rate for stage I was 79%, for stage II - 89%, for stage III - 33%. 3 year survival for highly virulent tumours - 56% and for low virulent (adenocarcinoma) - 82% was statistically different. The loss of tumour differentiation correlated with the worse prognosis: 3 year survival for G1 and G2 tumours was 92%, for G3 - 45%. Low hemoglobin level was also associated with low survival rate: 2 year survival for Hb≥120g/l was 85% and Hb<120g/l - 23%. 1 year survival rate was 87%, 3 year - 66%, 5 year - 58% for group II, treated with Cf-252. Radiation complications occurred for 13.8% of the patients for group I and 6.2% for group II. Good survival rates and a small number of complications sufficiently proofed treatment method. (author)

    To evaluate the growth pattern depicted by MR imaging and used to differentiate between uterine cervical and endometrial carcinoma where the mass involves both the uterine corpus and cervix. The tumor growth pattern observed on MR images obtained between November 1989 and January in 1999 in 37 of 784 cervical carcinomas and 9 of 47 endometrial carcinomas in which the tumor involved both the uterine corpus and cervix was analysed. The histologic type was squamous (n=29), adenocarcinomatous (n=6) or adenosquamous (n=2) in cervical carcinoma, and carcinomatous (n=8) or adenosquamous (n=1) in endometrial carcinoma. A 1.5-T (Magnetom Vision, Siemens, Germany) and a 2.0-T unit (Spectro-20000, Goldstar, Korea) were used to obtain T1-and T2-weighted axial, T2-weighted sagittal and Gd-enhanced images. Tumor involvement of the uterine cervix was classified as Cp-n, Cp-x, or Cp-b according to involvement of the endocervix, exocervix or both. Tumors of the uterine corpus were classified as involving the mucosa(U-mu), myometrium(U-my) or serosa(U-se). In 37 cases of cervical carcinoma, all three involving the endocervix(Cp-n) invaded the endometrium(U-mu), three involving both the endo- and exocervix(Cp-b) invaded the endometrium(U-mu, 1 case), myometrium(U-my, 1 case), or serosa(U-se, 1 case), and 31 involving the full-thickness of the uterine cervix(Ct) invaded the endometrium (U-mu, 6 cases) or serosa(U-se, 25 cases). In nine cases of endometrial carcinoma, three involving the endometrium(U-mu) and five involving the myometrium(U-my) invaded the endocervix(Cp-n), and one involving the serosa(U-se) invaded the full-thickness of the uterine cervix(Ct). Cervical carcinoma tended to involve the entire cervix and the full thickness of the uterine corpus, but endometrial carcinoma tended to involve the endometrium or myometrium of the uterine corpus and endocervix

    1993-10-01

    Ulex europaeus agglutinin I (UEA-I), a lectin which specifically binds L-fucose, has been shown to extensively bind endometrial carcinoma cells but not benign endometrial glands. Patterns of UEA-I binding were examined in five cases of uteri containing proliferative endometrium, five cases of endometrial hyperplasia, and 54 cases of endometrioid (typical) carcinoma of the endometrium and correlated with the histologic features of the tumor and its behavior. Whereas proliferative endometrium showed luminal staining only, diffuse cytoplasmic staining was frequently seen in hyperplasia and carcinoma. Carcinomas with a high percentage of tumor cells staining with UEA-I tended to be high-grade with a greater tendency to deep myometrial and vascular invasion than tumors with little or no staining. By univariate survival analysis, the extent of UEA-I binding was found to correlate with patient survival. By multivariate analysis, however, survival correlated most closely with the presence of deep myometrial and vascular invasion, and UEA-I binding was not found to be an independent prognostic indicator. This study suggests that increased fucosylation of proteins in endometrioid cancer cells may play a role in myometrial and vascular invasion.

    Lipocalin 2 (LCN2) is a secretory protein that is involved in various physiological processes including iron transport. We previously identified LCN2 as an up-regulated gene in endometrial carcinoma, and found that the overexpression of LCN2 and its receptor, SLC22A17, was associated with a poor prognosis. However, the functions and mechanism of action of LCN2 currently remain unclear. The LCN2-overexpressing endometrial carcinoma cell lines, HHUA and RL95-2, and LCN2-low-expressing one, HEC1B, were used. The effects of LCN2 on cell migration, cell viability, and apoptosis under various stresses, including ultraviolet (UV) irradiation and cisplatin treatment, were examined using the scratch wound healing assay, WST-1 assay, and Apostrand assay, respectively. LCN2-silencing using shRNA method significantly reduced the migration ability of cells (pendometrial carcinoma cells under various stresses in an iron-dependent manner. The survival function of LCN2 may be exerted through the PI3K pathway and suppression of the p53-p21 pathway. These functions of LCN2 may increase the malignant potential of endometrial carcinoma cells.

    Squamous cell carcinoma (SCC) of the endometrium, whether primary or secondary to cervical cancer, is a rare entity. Primary endometrial squamous cell carcinoma in situ is even more uncommon; it usually occurs in postmenopausal women and has a strong association with pyometra. We report a 60-year-old multiparous postmenopausal woman who presented to the Hakeem Abdul Hameed Centenary Hospital, New Delhi, India, in May 2014 with a lower abdominal swelling corresponding in size to a pregnancy of 26 gestational weeks and vaginal discharge of one year's duration. A total abdominal hysterectomy with a bilateral salpingooophorectomy was performed, which revealed an enlarged uterus with pyometra. Histopathology showed that the entire endometrial lining had been replaced with malignant squamous cells without invasion of the myometrium. Immunohistochemistry revealed that the tumour cells were positive for p63 with a high Ki-67 labelling index. No adjuvant therapy was required and the patient was disease-free at a seven-month follow-up.

    Full Text Available Abstract Background Endometrial carcinoma (EC is the most common malignancy of the female genital tract. Gene alterations and overexpression of various oncogenes are important in tumor development. The human HER 2 neu (c-erbB-2 gene product is a transmembrane receptor with an intracellular tyrosine kinase that plays an important role in coordinating the endometrial growth factor receptor signaling network. The aim of this study was to investigate the expression of c-erbB-2 in endometrial cancer, to study its correlation to established prognostic parameters and estrogen receptor (ER and progesterone receptor (PR status. Methods Immunohistochemical (IHC analyses of ER, PR and c-erbB-2 were performed in 72 EC cases. Results We detected a positive staining with c erbB 2 in 18.1% of the cases and determined a statistically significant relation between c-erbB-2 and PR. We could not find a statistically significant relation between c-erbB-2 staining and ER. There was not a statistically significant difference between c-erbB-2 and histological grade. The highest level of c-erbB-2 was found in grade 2 cases. There was not any statistically significant relation between c-erbB-2 and menstrual status, myometrial invasion, lymph node status, stage and survival. Conclusions Although our study provides additional evidence of the potential prognostic role of c-erbB-2, further prospective and controlled studies are required to validate their clinical usefulness.

    Purpose: To evaluate the very long-term results of the randomized Post Operative Radiation Therapy in Endometrial Carcinoma (PORTEC)-1 trial for patients with Stage I endometrial carcinoma (EC), focusing on the role of prognostic factors for treatment selection and the long-term risk of second cancers. Patients and Methods: The PORTEC trial (1990-1997) included 714 patients with Stage IC Grade 1-2 or Stage IB Grade 2-3 EC. After surgery, patients were randomly allocated to external-beam pelvic radiotherapy (EBRT) or no additional treatment (NAT). Analysis was by intention to treat. Results: 426 patients were alive at the date of analysis. The median follow-up time was 13.3 years. The 15-year actuarial locoregional recurrence (LRR) rates were 6% for EBRT vs. 15.5% for NAT (p < 0.0001). The 15-year overall survival was 52% vs. 60% (p = 0.14), and the failure-free survival was 50% vs. 54% (p = 0.94). For patients with high-intermediate risk criteria, the 15-year overall survival was 41% vs. 48% (p = 0.51), and the 15-year EC-related death was 14% vs. 13%. Most LRR in the NAT group were vaginal recurrences (11.0% of 15.5%). The 15-year rates of distant metastases were 9% vs. 7% (p = 0.25). Second primary cancers had been diagnosed over 15 years in 19% of all patients, 22% vs. 16% for EBRT vs. NAT (p = 0.10), with observed vs. expected ratios of 1.6 (EBRT) and 1.2 (NAT) compared with a matched population (p = NS). Multivariate analysis confirmed the prognostic significance of Grade 3 for LRR (hazard ratio [HR] 3.4, p = 0.0003) and for EC death (HR 7.3, p < 0.0001), of age >60 (HR 3.9, p = 0.002 for LRR and 2.7, p = 0.01 for EC death) and myometrial invasion >50% (HR 1.9, p = 0.03 and HR 1.9, p = 0.02). Conclusions: The 15-year outcomes of PORTEC-1 confirm the relevance of HIR criteria for treatment selection, and a trend for long-term risk of second cancers. EBRT should be avoided in patients with low- and intermediate-risk EC.

    Purpose : To obtain the optical treatment method in patients with endometrial carcinoma(clinical stage FIGO I, II) by comparative analysis between preoperative radiotherapy(pre-op R) and postoperative radiotherapy(post-op RT). Materials and Methods : A retrospective review of 62 endometrial carcinoma patients referred to the Yonsei Cancer Center for radiotherapy between 1985 and 1991 was undertaken. Of 62 patients, 19 patients(Stage I; 12 patients, Stage II; 7 patients) received pre-op RT before TAH(Total Abdominal Hysterectomy) and BSO(Bilateral Salphingoophorectomy) (Group 1) and 43 patients( Stage 1; 32 patients, Stage 2; 11 patients) received post-op RT after TAH and BSO (Group 2). Pre-op irradiation was given 4-6 weeks prior to surgery and post-op RT was administered on 4-5 weeks following surgery. All patients exept 1 patient(Group2; ICR alone) received external irradiation. Seventy percent(13/19) of pre-op RT group and 54 percent(23/42) of post-op RT group received external pelvic irradiation and intracavitary radiation therapy(ICR). External radiation dose was 39.6-55Gy(median 45Gy) in 5-6 week through opposed AP/PA fields or 4-field box technique treating daily, five days per week, 180cGy per fraction. ICR doses were prescribed to point A(20-39.6 Gy, median 39Gy) in Group 1 and 0.5cm depth from vaginal surface (18-30 Gy, median 21Gy) in Group2. Results : The overall 5 year survival rate was 95%. No survival difference between pre-op and post-op RT group.(89.3% vs 97.7%, p>0.1) There was no survival difference by stage, grade and histology between two groups. The survival rate was not affected by presence of residual tumor of surgical specimen after pre-op RT in Group 1(p>0.1), but affected by presence of lymph node metastasis in post-op RT group(p<0.5). The complication rate of pre-op RT group was higher than post-op RT.(16% vs 5%) Conclusion : Post-op radiotherapy offers the advantages of accurate surgical-pathological staging and low complication rate

    There have been a limited number of studies giving the incidence of pleural metastasis from female genital tract tumors. An unusual case occurred of recurrent pleural malignant effusion associated with disseminated serous papillary endometrial adenocarcinoma (EC). A total abdominal hysterectomy with bilateral salpingo-oophorectomy, pelvic lymphadenectomy, appendectomy and omentectomy was performed. Treatment of the pleural malignant effusion consisted of thoracotomy with partial decortication, systemic chemotherapy and radiotherapy. The patient died of circulatory failure 8 months after the primary diagnosis. Although the pleura is a rare site of widespread EC, one should recognize the possibility of pleural spread from female genital tract neoplasms presenting with associated symptoms. Cytopathologic examination of the pleural effusion and the finding ofcarcinoma cells mandate an investigation for the primary site of the neoplasm by a multidisciplinary group.

    To evaluate MR capacity in assessing deep myometrial and cervical infiltrations in cases of endometrial carcinoma. A series of 30 consecutively diagnosed endometrial cancer patients was pre-surgically evaluated by means of magnetic resonance (MR). TSE-T2 sequences with fat saturation and dynamic FFe sequence were used after gadolinium administration. A correlation with post-surgical histological stating was made. There were then determined sensitivity (S), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV) for the deep myometrial infiltration and cervical invasion. Cases of overestimation and underestimation were analyzed. Values obtained for myometrium and cervix were, respectively, S of 67% and 63%, SP of 89% and 91%, PPV of 80% and 71% and NPV of 80% and 87%. Two cases each were over valued for myometrial infiltration and cervix: four cases and 3 cases, respectively, were undervalues. MR stating in cases of endometrial carcinoma is a highly reliable diagnostic technique, but it does present certain limitations. (Author) 19 refs

    A new cell line of human uterine endometrial undifferentiated carcinoma, designated as TMG-L, was established from the metastatic lymph node of 56-year-old patient TMG-L cells have been cultured with Ham's F-12 medium supplemented with 10% FCS and grew as a loosely adherent monolayer with polygonal or spindle-shaped cells exhibiting poor cell-cell contact and piled up against each other, showing a tendency to grow as floating cells. The doubling time of this cell line was about 48 hours, and chromosomal analysis revealed aneuploidy at passage 25. The cells formed tumors in SCID mouse, the histology of which was similar to that of undifferentiated carcinoma component of primary tumor. TMG-L cells showed the loss of expression and membranous localization of either E-cadherin or alpha-catenin, implied corresponding loss of their adhesive function. And this dysfunction implicated the biological aggressive behavior of uterine endometrial undifferentiated carcinoma. This cell line appears to provide a useful system for studying uterine undifferentiated carcinoma in vivo and in vitro.

    Background: in advanced vaginal recurrences of cervical and endometrial carcinomas therapeutic options are rare because of preceding therapy. Patients and methods: 23 patients developing advanced vaginal recurrences of cervical and endometrial carcinomas were included. 15 patients started with external-beam therapy to the pelvis and eight patients after preceding radiotherapy underwent brachytherapy alone. All patients had ultrasound-guided implantation of transvaginal or transperineal interstitial needles for brachytherapy. Median prescribed total dose was 64 Gy. Results: 18 patients (78%) achieved complete remission. Six patients are alive without tumor and one with tumor after a median follow-up of 64 months. 14 patients died of tumor and two of intercurrent disease. 5-year disease-specific survival and local control rate were 43% and 47%, respectively, in patients with complete remission. Univariate analysis found time to relapse > 2 years, initial diameter {<=} 4 cm, initial volume < 15 cm{sup 3}, no extension to the pelvic side wall, volume before brachytherapy < 7.5 cm{sup 3}, brachytherapy coverage index > 0.8, and prescribed total dose > 64 Gy being positive predictors for local control and survival. Conclusion: the use of ultrasound guidance for placement of interstitial needles in template-based brachytherapy of advanced recurrent gynecologic malignancies is a feasible, safe, and cheap method with encouraging results. Today, ultrasound imaging can be also used to some extent for treatment planning which requires further development. Patient- and treatment-related prognostic factors can be defined. (orig.)

    Purpose: To describe an original brachytherapy technique using a dedicated intravaginal template for the treatment of vaginal vault recurrences and to evaluate the results of such a treatment. Methods and Materials: Between 1978 and 1993, 78 patients with isolated recurrence of cervical or endometrial carcinoma located in the vaginal vault have been treated in Lyon. Initial treatment was surgery alone in 49 cases and irradiation with surgery in 37 cases. Treatment of the vaginal recurrence was performed with interstitial Iridium 192 brachytherapy combined with pelvic external beam radiation therapy in 34 patients. The tumor was implanted with a dedicated intravaginal plastic template. Six parallel metallic needles were implanted in the vaginal vault and afterloaded with Iridium 192 wires of 4 to 6 cm long. The mucosa of the upper half of the vagina received the same dose as the one encompassing the tumor on the 85% isodose of the Paris system. Results: At 5 years the local control rate was 70% and the overall survival rate 56%. Grade 3 complications occurred in 10% of the cases and only in patients who had received irradiation during the initial treatment of the primary tumor. Conclusions: This brachytherapy technique makes it possible to perform Iridium 192 implants in a difficult situation with a favorable long-term control rate and an acceptable rate of complications

    MFE-280 endometrial cancer cells express PP14 (placental protein 14) in vitro. PP14 is normally found in the secretory endometrium and in placental tissue. MFE-280 cells, which are tumorigenic in nude mice, were derived from a recurrent, poorly differentiated endometrial carcinoma. The cells were initially grown in suspension culture and later transferred to monolayer cultures. Karyotyping revealed near-diploidy with a complex heterogeneous aberration pattern. MFE-280 cells were positive for the cytokeratins 7, 8, 18 and 19 as well as for vimentin. The expression of PP14 in MFE-280 cells was demonstrated by immunochemistry and reverse transcriptase--polymerase chain reaction. PP14-mRNA was also detected in one out of five endometrial cancer specimen. In tumor tissue the expression of PP14 was not dependent on progestins.

    To evaluate the misdiagnosis between endometrial biopsy and definitive surgical pathology and to assess whether the failure in recognizing preoperatively high-risk endometrial carcinoma (EC) can impact oncological outcomes. A retrospective study was conducted to evaluate patients with EC diagnosed by preoperative endometrial biopsy who subsequently underwent surgical staging between 2006 and 2013 at our institution. In patients with a surgical diagnosis of high-risk EC, histotype and grade change between the endometrial biopsy and surgical specimen (discordance diagnosis) were evaluated and correlated to survival outcomes. Cox's regression model for multivariable analysis was used to evaluate the effect of several variables (age, stage, discordance in diagnosis, co-morbidities, frozen section, extensive surgical staging and adjuvant chemotherapy) on the survival rate. Data from 447 patients were reviewed. Among 109 women with surgical diagnosis of high-risk EC, 35 (32.1%) were preoperatively misdiagnosed. Of these 35 women, 24 (68.6%) cases were upgraded to grade 3, and 11 (3.4%) were upgraded to serous or clear cell type in the definitive specimen. The 5-year overall survival (OS; 70.2 vs. 86.8%; p=0.029), disease-specific survival (DSS; 72.5 vs. 88.2%; p=0.039) and recurrence free survival (RFS; 62.6 vs. 82.5%; p=0.024) were significantly lower in the high-risk EC patients who were preoperatively undiagnosed in the endometrial biopsy compared with patients with an appropriate preoperative histological diagnosis. Controlling for age, stage, co-morbidities, frozen section, extensive surgical staging and adjuvant chemotherapy, multivariable analysis revealed that discordance in diagnosis was associated with poorer survival outcomes. Failure to recognize preoperatively high-risk ECs is associated with worse outcomes. Copyright © 2015 The Authors. Published by Elsevier Ireland Ltd.. All rights reserved.

    Endometrial cancer is a clinically heterogeneous disease and it is becoming increasingly clear that this heterogeneity may be a function of the diversity of the underlying molecular alterations. Recent large-scale genomic studies have revealed that endometrial cancer can be divided into at least four distinct molecular subtypes, with well-described underlying genomic aberrations. These subtypes can be reliably delineated and carry significant prognostic as well as predictive information; embracing and incorporating them into clinical practice is thus attractive. The road towards the integration of molecular features into current classification systems is not without obstacles. Collaborative studies engaging research teams from across the world are working to define pragmatic assays, improve risk stratification systems by combining molecular features and traditional clinicopathological parameters, and determine how molecular classification can be optimally utilized to direct patient care. Pathologists and clinicians caring for women with endometrial cancer need to engage with and understand the possibilities and limitations of this new approach, because integration of molecular classification of endometrial cancers is anticipated to become an essential part of gynaecological pathology practice. This review will describe the challenges in current systems of endometrial carcinoma classification, the evolution of new molecular technologies that define prognostically distinct molecular subtypes, and potential applications of molecular classification as a step towards precision medicine and refining care for individuals with the most common gynaecological cancer in the developed world.

    Objective: To analyse the effect of preoperative persistent infusion chemotherapy via uterine artery on endometrial carcinoma and followed by hysterectomy. Methods: According to the Seldinger's technique, polyethylene catheter was super selected into the uterine artery. The drugs were infused with cisplatin 100 mg and doxorubicin 50 mg in a consecutive low-dose method for five days. Radical surgery was performed about three or four weeks after NAC. The NAC group (n = 20) underwent surgery following intra-arterial chemotherapy, while the control group (n = 40) was randomly selected among the patients of endometrial carcinoma performed operations in the hospital. Results: One (5.0%) patient showed complete response in NAC group, the rates of complete response plus partial response were 60.0%. There were no significant differences in bleeding amounts, the operation time, the function recovery of bladder and bowel, the healing time of the incision between the two groups. Compared with the control group, infiltration larger than half of myometrium and lymph nodes involvement were statistically significant lower in NAC group (P < 0.05). Conclusions: Preparing intra-arterial chemotherapy may reduce tumor volume and possibly eradicate subclinical metastases without increasing the incidence of operative complications

    A high dose-rate afterloading technique ( 60 Co) was compared with a low dose-rate packing method ( 226 Ra) in the treatment of endometrical carcinoma stage I. In all, 1021 patients treated during the period 1977-1986 at two Swedish gynecologic oncology centers were analyzed regarding treatment set-up, histopathologic outcome in the operative specimens, recurrence rates, survival rates and radiation side effects. Complete tumor eradication in the operative specimen was achieved in 80% after radium therapy and in 60% after irradiation by the high dose-rate technique. The overall recurrence rate was 15.7% in the radium packing series and 11.5% after cobalt afterloading treatment. The risk of pelvic recurrences increased by 2.1-2.6 if hysterectomy was replaced by dilatation and curettage. The two radiation techniques seemed t be comparable with regard to the risk of both pelvic recurrences and distant metastases. The 5-year crude survival rates were 85% in the afterloading series and 82% in the radium series. The corrected survival rates were similar (90%) for the two techniques. Age, tumor grade and uterine size were significant prognostic factors with regard to the probability of death due to cancer. Early radiation reactions had quite similar rates in the two series, whereas late radiation reactions were more frequent in the high dose-rate afterloading group in the 10-12 Gy dose fraction range, but not in the 5-8 Gy range. The radium packing method seemed to give a higher frequency of tumor-free operative specimens in this study, but with regard to recurrence rates and survival probabilities the techniques were comparable. Since the different proportion of surgery in the two series and the histopathologic evaluation might have influenced the rate of local tumor eradication in the operative specimens and the risk of pelvic recurrences the results must be assessed with great caution and only a crude comparison of the two treatment techniques could be made.

    Magnetic resonance imaging (MRI) provides precise staging of endometrial carcinoma. However, we have sometimes experienced patients with microscopic extrauterine extension in whom MRI showed the disease as being limited to the uterus. We studied indirect MRI signs for microscopic extrauterine spread of endometrial carcinoma which outwardly seemed to be limited to within the uterus. MRI studies and the clinical records of 100 patients with surgically proven endometrial carcinoma were retrospectively reviewed. We evaluated: MRI staging, tumor growing at the orifices of the fallopian tube in the uterine fundus, hydrosalpinx, and ascites, in each MRI study. Surgical specimens showed that 12 of the 100 patients had extrauterine spread, with 1 patient showing both ovarian extension and omental metastasis; there ovarian extension in 3, extension to the fallopian tubes in 3, omental metastasis in 1, and positive peritoneal cytology in 4. Tumor growing at the orifices of the fallopian tubes with deep myometrial invasion showed higher accuracy for predicting microscopic intrauterine spread (82.0%) although it was not significantly different from the accuracy of deep myometrial invasion anywhere within the uterus (75.0%). However, tumor growing at the orifices of the fallopian tubes in patients with stage Ia disease showed a high negative predictive value (89.7%). Hydrosalpinx had the highest specificity (98.9%) and accuracy (88.0%); however, it did not seem to be practical because it was observed in only 2 patients. Ascites in postmenopausal patients showed higher specificity (93.5%), although it was not considered to be useful in the premenopausal patients. Tumor extension at the orifices of the fallopian tubes in patients with stage Ia disease, and ascites in postmenopausal patients on MRI seemed to be predictive factors for microscopic extrauterine spread.

    Background: To investigate the diagnostic efficacy of preoperative lymphoscintigraphy (LS), Ga-67 scintigraphy (GS) and computed tomography (CT) for detection of lymph node metastasis in patients with endometrial or ovarian carcinoma. Methods: The results of preoperative LS, GS and CT used to detect lymph node metastasis were compared to the postoperative histopathological results of lymph node dissection materials of a total of 37 patients, including 16 patients with endometrial and 21 patients with ovarian carcinomas. The diagnostic efficacy of these methods for detecting lymph node metastasis were calculated. Results: When the results of all of the patients were taken into account, the preoperative LS, GS and CT were found to have sensitivities of 50%, 20% and 40% and specificities of 51.8%, 96.3%, and 92.6%, respectively, for detection of pelvic lymph node metastasis. The same methods had sensitivities of 27.3%, 27.3% and 72.7% and specificities of 88.5%, 88.5%, 84.6%, respectively, for detecting para-aortic lymph node metastasis in all patients. Conclusion: These data suggested that although LS, GS and CT had relatively high specificity, low sensitivity of these imaging methods precluded their routine preoperative use for diagnosis of lymph node metastasis of ovarian or endometrial carcinoma.

    Purpose: Adjuvant radiation therapy (RT) has been shown to improve local control in patients with endometrial carcinoma. We analyzed the impact of the time interval between hysterectomy and RT initiation in patients with endometrial carcinoma. Methods and Materials: In this institutional review board-approved study, we identified 308 patients with endometrial carcinoma who received adjuvant RT after hysterectomy. All patients had undergone hysterectomy, oophorectomy, and pelvic and para-aortic lymph node evaluation from 1988 to 2010. Patients' demographics, pathologic features, and treatments were compared. The time interval between hysterectomy and the start of RT was calculated. The effects of time interval on recurrence-free (RFS), disease-specific (DSS), and overall survival (OS) were calculated. Following univariate analysis, multivariate modeling was performed. Results: The median age and follow-up for the study cohort was 65 years and 72 months, respectively. Eighty-five percent of the patients had endometrioid carcinoma. RT was delivered with high-dose-rate brachytherapy alone (29%), pelvic RT alone (20%), or both (51%). Median time interval to start RT was 42 days (range, 21-130 days). A total of 269 patients (74%) started their RT <9 weeks after undergoing hysterectomy (group 1) and 26% started ≥9 weeks after surgery (group 2). There were a total of 43 recurrences. Tumor recurrence was significantly associated with treatment delay of ≥9 weeks, with 5-year RFS of 90% for group 1 compared to only 39% for group 2 (P<.001). On multivariate analysis, RT delay of ≥9 weeks (P<.001), presence of lymphovascular space involvement (P=.001), and higher International Federation of Gynecology and Obstetrics grade (P=.012) were independent predictors of recurrence. In addition, RT delay of ≥9 weeks was an independent significant predictor for worse DSS and OS (P=.001 and P=.01, respectively). Conclusions: Delay in administering adjuvant RT after

    Fifteen patients who developed cancer of the endometrium 10 or more years after pelvic irradiation for carcinoma were selected for study from a group of 64 cases of postirradiation malignant pelvic tumors diagnosed during a 48-year span. The average interval between radiotherapy and diagnosis of the subsequent endometrial cancer was 17.2 years. Irradiation initially had been done for squamous cell carcinoma of the cervix in 13 cases (87%) and for ovarian tumors in two instances. Almost all patients had received megavoltage external radiation combined with radium implants. Two-thirds of the tumors were adenocarcinomas and one-third were carcinosarcomas (either homologous or heterologous). Although the risk of second primary malignant tumors following therapeutic irradiation for pelvic tumors probably is very low, the emergence of new genital tract cancers in long-term survivors must be anticipated, regardless of whether the postirradiation cancers are spontaneous or radiation-induced

    To determine the clinicopathological significance of the DNA methyltransferase 3B (DNMT3B) overexpression in endometrial carcinomas and to evaluate its correlation with hormone receptor status. Immunohistochemistry was performed to assess the expression of DNMT3B and hormone receptors in 104 endometrial carcinomas. DNMT3B overexpression occurred frequently in endometrioid carcinoma (EC, 54.8%) more than in nonendometrioid carcinoma (NEC, 30.0%) with statistical significance (P=0.028). Furthermore, there was a trend that EC with worse clinico-pathological variables and shorter survival had a higher DNMT3B expression, and the correlation between DNMT3B and tumor grade reached statistical significance (P=0.019).A negative correlation between DNMT3B and estrogen receptor (ER) or progesterone receptor (PR) expression was found in EC. NMT3B overexpression occurred frequently in the ER or PR negative subgroups (78.9%, 86.7%) more than in the positive subgroups (47.7%, 47.8%) with statistical significance (P=0.016, P=0.006). In addition, the DNMT3B overexpression increased in tumors with both ER and PR negative expression (92.9%, P=0.002). However, no such correlation was found in NEC (P>0.05). Sequence analyses demonstrated multiple ER and PR binding sites in the promoter regions of DNMT3B gene. This study showed that the expression of DNMT3B in EC and NEC was different. DNMT3B overexpression in EC was associated with the worse clinicopathological variables and might have predictive value. The methylation status of EC and NEC maybe different. In addition, in EC, DNMT3B overexpression negatively correlated with ER or PR expression. In NEC, the correlation between DNMT3B and ER or PR status was not present.

    Full Text Available Squamous cell carcinoma (SCC of the endometrium, whether primary or secondary to cervical cancer, is a rare entity. Primary endometrial squamous cell carcinoma in situ is even more uncommon; it usually occurs in postmenopausal women and has a strong association with pyometra. We report a 60-year-old multiparous postmenopausal woman who presented to the Hakeem Abdul Hameed Centenary Hospital, New Delhi, India, in May 2014 with a lower abdominal swelling corresponding in size to a pregnancy of 26 gestational weeks and vaginal discharge of one year’s duration. A total abdominal hysterectomy with a bilateral salpingooophorectomy was performed, which revealed an enlarged uterus with pyometra. Histopathology showed that the entire endometrial lining had been replaced with malignant squamous cells without invasion of the myometrium. Immunohistochemistry revealed that the tumour cells were positive for p63 with a high Ki-67 labelling index. No adjuvant therapy was required and the patient was disease-free at a seven-month follow-up.

    The purpose of this study was to determine the incidence of, and risk factors for, surgical site infections in a contemporary cohort of women with endometrial carcinoma. We retrospectively studied 1164 women treated for endometrial carcinoma by hysterectomy at a single institution in 2007-2013. In all, 912 women (78.4%) had minimally invasive hysterectomy. Data on surgical site infections were collected from medical records. Univariate and multivariate analyses were used to identify risk factors for incisional and organ/space infections. Ninety-four women (8.1%) were diagnosed with a surgical site infection. Twenty women (1.7%) had an incisional infection and 74 (6.4%) had an organ/space infection. The associations of 17 clinico-pathologic and surgical variables were tested by univariate analyses. Those variables that were identified as potential risk factors in univariate analyses (p infections as dependent variables. Obesity (body mass index ≥ 30 kg/m(2)), diabetes, and long operative time (>80th centile) were independently associated with a higher risk of incisional infection, whereas minimally invasive surgery was associated with a smaller risk. Smoking, conversion to laparotomy, and lymphadenectomy were associated with a higher risk of organ/space infection. Organ/space infections comprised the majority of surgical site infections. Risk factors for incisional and organ/space infections differed. Minimally invasive hysterectomy was associated with a smaller risk of incisional infections but not of organ/space infections. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

    Full Text Available Mechanisms governing the metastasis of endometrial carcinoma (EC are poorly defined. Recent data support a role for the cell surface receptor tyrosine kinase TrkB in the progression of several human tumors. Here we present evidence for a direct role of TrkB in human EC. Immunohistochemical analysis revealed that TrkB and its secreted ligand, brain-derived neurotrophic factor (BDNF, are more highly expressed in EC than in normal endometrium. High TrkB levels correlated with lymph node metastasis (p<0.05 and lymphovascular space involvement (p<0.05 in EC. Depletion of TrkB by stable shRNA-mediated knockdown decreased the migratory and invasive capacity of cancer cell lines in vitro and resulted in anoikis in suspended cells. Conversely, exogenous expression of TrkB increased cell migration and invasion and promoted anoikis resistance in suspension culture. Furthermore, over-expression of TrkB or stimulation by BDNF resulted in altered the expression of molecular mediators of the epithelial-to-mesenchymal transition (EMT. RNA interference (RNAi-mediated depletion of the downstream regulator, Twist, blocked TrkB-induced EMT-like transformation. The use of in vivo models revealed decreased peritoneal dissemination in TrkB-depleted EC cells. Additionally, TrkB-depleted EC cells underwent mesenchymal-to-epithelial transition and anoikis in vivo. Our data support a novel function for TrkB in promoting EMT and resistance to anoikis. Thus, TrkB may constitute a potential therapeutic target in human EC.

    Introduction Hypoxia-Inducible Factor 1α (HIF-1α) is one of the major adaptive responses to hypoxia, regulating the activity of glucose transporter -1 (GLUT-1), responsible for glucose uptake. Aim To evaluate the immunohistochemical expression of both HIF-1α and GLUT-1 in type I and II endometrial carcinoma and their correlation with the available clinicopathologic variables in each type. Materials and Methods A retrospective study was conducted on archival blocks diagnosed from pathology department between April 2010 and August 2014 included 9 cases of atypical hyperplasia and 67 cases of endometrial carcinoma. Evaluation of both HIF-1α and GLUT-1 expression using standard immunohistochemical techniques performed on cut sections from selected paraffin embedded blocks. Statistical Analysis Descriptive analysis of the variables and statistical significances were calculated by non-parametric chi-square test using the Statistical Package for the Social Sciences version 12.0 (SPSS). Results HIF-1α was expressed in epithelial (88.9%, 52.2%, 61.2% and 50%) and stromal (33.3%, 74.6%. 71.4% and 83.3%) components of hyperplasia, total cases of EC, type I and II EC, respectively. GLUT-1 was expressed in the epithelial component of 88.9%, 98.5%, 98% and 100% of hyperplasia, total EC cases, type I and II EC, respectively. The necrosis related pattern of epithelial HIF-1α expression was in favour of type II (p=0.018) and grade III (p=0.038). HIF-1α H-score was associated with high apoptosis in both type I and total cases of EC (p=0.04). GLUT-1 H-score was negatively correlated with apoptotic count (p=0.04) and associated with high grade (p=0.003) and advanced stage in total EC (p=0.004). GLUT-1 H-score was correlated with the pattern of HIF-1α staining in all cases of EC (p= 0.04). Conclusion The role of HIF-1α in epithelial cells may differ from that of stromal cells in EC; however they augment the expression of each other supporting the crosstalk between them. The

    Introduction: In a retrospective analysis side effects, relapse rates and the value of in vivo dosimetry for vaginal HDR-brachytherapy (BT) in women with endometrial carcinoma are evaluated. Material and Methods: From 1987 to 1993 124 women received vaginal HDR-BT (Ir-192) only for adjuvant treatment of early endometrial carcinoma. The usual fractionation was 1x7 Gy per week applied to the surface of the vaginal cylinder to a total dose of 21 Gy. During BT we performed in vivo dosimetry using bladder and rectal probes. The measured doses per patient in the bladder ranged from 1.5 to 9.8 Gy, 6.7 Gy in the mean. In the rectum the mean dose was 8.2 Gy (1.7 to 13.8 Gy). Results: The analysis of side effects shows that only 23 of 124 women (18 %) reported any problems at all. 13 women (10 %) noticed dysuria or pollakisuria for a maximum of 6 weeks. The average measured bladder dose in those patients was 5.3 Gy, (below the average bladder dose of 6.7 Gy). Diarrhea was reported in 3 patients (2 %), in those the average measured rectal dose was 6.8 Gy (lower than the average rectal dose of 8.2 Gy). 6 women (5 %) received antibiotic treatment because of bacteriuria. Of all patients 10 (8%) had a pelvic relapse, 3 in the vagina only. 5 women showed distant metastases during follow-up (3 of those having also a local relapse). Discussion and Conclusion: With only 2 % vaginal relapses HDR-BT is a save method to reduce the probability of vaginal metastases of endometrial carcinoma in an adjuvant setting. Moreover the incidence of acute side effects is low, no lasting complications were seen in our patients. There existed no correlation between the incidence of side effects and the measured in vivo doses in bladder and rectum, questioning the future usage in the era of well advanced BT-planning systems

    We evaluated the efficacy and safety of the aromatase inhibitor exemestane in patients with advanced, persistent or recurrent endometrial carcinoma. We performed an open-label one-arm, two-stage, phase II study of 25 mg of oral exemestane in 51 patients with advanced (FIGO stage III-IV) or relapsed endometrioid endometrial cancer. Patients were stratified into subsets of estrogen receptor (ER) positive and ER negative patients. Recruitment to the ER negative group was stopped prematurely after 12 patients due to slow accrual. In the ER positive patients, we observed an overall response rate of 10%, and a lack of progression after 6 months in 35% of the patients. No responses were registered in the ER negative patients, and all had progressive disease within 6 months. For the total group of patients, the median progression free survival (PFS) was 3.1 months (95% CI: 2.0-4.1). In the ER positive patients the median PFS was 3.8 months (95% CI: 0.7-6.9) and in the ER negative patients it was 2.6 months (95% CI: 2.1-3-1). In the ER positive patients the median overall survival (OS) time was 13.3 months (95% CI: 7.7-18.9), in the ER negative patients the corresponding numbers were 6.1 months (95% CI: 4.1-8.2). Treatment with exemestane was well tolerated. Treatment of estrogen positive advanced or recurrent endometrial cancer with exemestane, an aromatase inhibitor, resulted in a response rate of 10% and lack of progression after 6 months in 35% of the patients.

    Background and purpose: The vagina is the site most commonly affected by loco-regional failure in endometrial carcinoma (EC). The aim of this study was to evaluate the efficacy of vaginal brachytherapy (BT) combined or not with whole pelvic external radiotherapy (RT) for the treatment of patients with vaginal recurrences from endometrial cancer. Patients and methods: Between 1986 and 1999 25 women were treated at the Institut Gustave Roussy (IGR) for a vaginal relapse (VR) from EC. Patient characteristics were as follows: median age 65 years (range 43-84), histologic type: adenocarcinoma (21 patients); endometrioid carcinoma (three patients); adenoacanthoma (one patient); FIGO staging for initial disease: Ia, three; Ib, eight; Ic, four; II, seven; IIIa, two; IVa, one. The initial tumor was treated by surgery alone in 18 patients, or surgery combined with RT and/or BT in seven patients. A VR occurred in a median interval of 21 months (range 2-89); 10/25 (40%) occurred within the first year following initial treatment. The recurrence was exclusively in the vagina in 18 patients and was associated with parametrial and or nodal involvement in seven patients; it was localized in the upper 1/3 of the vagina in nine patients, in the upper 2/3 or the entire vagina in 11 patients or in the lower 1/3 in five patients. The largest tumor diameter ranged from 10 to 70 mm (median: 25 mm). The treatment of the VR included low-dose rate endocavitary BT in all cases: three patients received endocavitary BT alone, or it was associated with external RT in 22 patients or delivered after surgical removal of the lesion in nine patients. Seven patients were submitted to further irradiation combining endocavitary and interstitial BT. Results: Local control was achieved in 23 patients (92%). With a follow-up ranging from 4 to 154 months, 13 patients have died (ten due to metastasis, two of intercurrent disease and two due to local tumor progression) and ten patients are alive and disease

Materials and Methods: Between January 1991 and December 2006, 35 patients with FIGO stages I and II disease, who received adjuvant radiation therapy following surgery for endometrial cancer at Ewha Womans University Hospital, were enrolled in this study. A total of 17 patients received postoperative pelvic external beam radiation therapy; whereas, 12 patients received vaginal brachytherapy alone, and 6 patients received both pelvic radiation therapy and vaginal brachytherapy. Results: The median follow-up period for all patients was 54 months. The 5-yr overall survival and disease-free survival rates for all patients were 91.4% and 81.7%, respectively. The 5-yr overall survival rates for low-risk, intermediate-risk, and high-risk groups were 100%, 100% and 55.6%, respectively. In addition, the 5-yr disease-free survival rates were 100%, 70.0%, and 45.7%, respectively. Although no locoregional relapses were identified, distant metastases were observed in 5 patients (14%). The most common site of distant metastases was the lung, followed by bone, liver, adrenal gland, and peritoneum. A univariate analysis revealed a significant correlation between distant metastases and risk-group (p=0.018), pathology type (p=0.001), and grade (p=0.019). A multivariate analysis also revealed that distant metastases were correlated with pathology type (p=0.009). Papillary, serous and clear cell carcinoma cases demonstrated a poor patient survival rate compared to cases of endometrioid adenocarcinoma or adenosquamous carcinoma. The most common complication of pelvic external beam radiation therapy was enteritis (30%), followed by proctitis, leucopenia, and lymphedema. All these complications were of RTOG grades 1 and 2; no grades 3 and 4 were observed. Conclusion: For the low-risk and intermediate-risk groups (stages 1 and 2) endometrial

    High-voltage irradiation of four ovarial carcinomas, four endometrial carcinomas and two carcinomas of the cervix is reported on which were transplanted subcutaneously to nu/nu mice. In all cases, the growth was stopped and the tumour receded under irradiation; in 8 cases, after stopping the irradiation with a dose of 30 to 60 Gy the growth went on. Of two carcinomas with decrease in the size and a stopped growth over 20 weeks, in one case no vital cells could be found any more while in the other one there were still numerous vital cells. These showed also after irradiation an unchanged radionucleotid incorporation in the single cell suspension. The effect of a high-voltage irradiation seems to be independent on the histologic picture, but dependent on the dose and the fractioning. The incorporation rates of 3 H-thymidine and 3 H-uridine in the single cell suspension reamined inchanged both before and after irradiation. Irradiation of the xenotransplantate of one side showed the exclusively local effect of this measure. This is confirmed by comparative examinations of the same tumours with a chemotherapy. Thus the nude mouse model offers the possibility of observing the effects of a high-voltage irradiation of human tissue in vivo without involving the total organism of the tumourous animal like in chemotherapy. This shows another field for future questions with nude mice. (orig.) [de

In endometrial carcinoma, it is important to accurately assess invasion depth and preoperative staging. Fusion of T2-weighted magnetic resonance imaging (T2WI and diffusion-weighted magnetic resonance imaging (DWI may contribute to the improvement of anatomical localization of lesions.Materials and methods: In our study, a total of 58 endometrial carcinoma cases were included. Based on the revised 2009 International Federation of Gynecology and Obstetrics staging system, a fusion of T2WI and DWI was utilized for the evaluation of invasion depth and determination of the overall stage. Postoperative pathologic assessment was considered as the reference standard. The consistency of T2WI image staging and pathologic staging, and the consistency of fused T2WI and DWI and pathologic staging were all analyzed using Kappa statistics.Results: Compared with the T2WI group, a significantly higher diagnostic accuracy was observed for myometrial invasion with fusion of T2WI and DWI (77.6% for T2WI; 94.8% for T2WI-DWI. For the identification of deep invasion, we calculated values for diagnostic sensitivity (69.2% for T2WI; 92.3% for T2WI-DWI, specificity (80% for T2WI; 95.6% for T2WI-DWI, positive predictive value (50% for T2WI; 85.7% for T2WI-DWI, and negative predictive value (90% for

    To explore the effect of demethylating drug 5-Aza-2'-deoxycytidine (5-Aza-CdR) on methtylation status of the Ras-association domain familylA gene (RASSF1A) in human endometrial carcinoma. Randomly'assign the human endometrial carcinoma cell line HEC-1-B into groups and use demethylating drug 5-Aza-CdR of different concentration to treat them. Then Methylation-specific polymerase chain reaction (MSP), real-time PCR, Western blot, TUNEL technology were used to analyze methylation status of RASSF1A promoter CpG islands, RASSF1A mRNA expression, RASSF1A protein expression and apoptosis of HEC-1-B cell. High DNA methylation in RASSF1A gene promoter region, low RASSF1A mRNA level and protein expression and out of control of human endometrial carcinoma cell HEC-1-B apoptosis were observed. 5-Aza-CdR of different concentration could reverse RASSF1A gene's methylation status, recover the expression of mRNA and protein, and control the growth of HEC-1-B by inducing apoptosis. Aberrant methylation of RASSF1A in endometrial cancer as a therapeutic target, demethylating agent 5-Aza-CdR could be an effective way of gene therapy.

    To detect the expression of Pokemon in endometrial carcinoma (EC), to provide preliminary theoretical basis for clarifying pathogenesis and searching for effective targets. Ninety-eight cases of endometrial tissue paraffin specimens form July 2012 to July 2014 in West China Second University Hospital, Sichuan University, were collected, including: EC group, consisting of adenocarcinoma 23 cases, adenosquamous 12 cases, serous 3 cases, mucinous 11 cases and clear cell 9 cases, and control group, consisting of atypical hyperplasia endometrium 20 cases and normal endometrium 20 cases (secretory 10 cases, hyperplasia 10 cases). Immunohistochemistry was used to detect the expression of Pokemonin each section, analyzing the correlation of Pokemon expression with clinicopathologic characteristics and p53 expression. The positive rate of Pokemon in normal endometrium was 25% (5/20), significantly lower than that in atypical hyperplasia endometrium (60.0%, 12/20) and EC (93.1%, 54/58) (P Pokemon in III-IV stage, type II and Ki-67 ≥ 50 EC tissue was much higher (P = 0.012, 0.023, 0.029). In type II EC tissue, the correlation index between Pokemon and p53 is 0.669 (P = 0.000). The over expression of Pokemon upregulates the expression of mutant p53, which may be one of the carcinogenesis modes in type II EC.

    We compared concentrations of cytosolic estrogen receptors (ERc) measured in 35 postmenopausal endometrial carcinomas by ligand binding method (LBA) (dextran-coated charcoal assay) and enzyme immunoassay (EIA). Correlations between ERc, nuclear estrogen receptors (ERn) determined by EIA......, and cytosolic progesterone receptors (PR) measured by LBA were also studied. While ERc concentrations determined by LBA and EIA were highly correlated (r: 0.94), ERc values detected by LBA were approximately twice those found by EIA (median values of ERc: 155 vs. 64 fmol/mg cytosol protein, DCC vs. EIA......). The percentages of ERc positive tumors were 89% by LBA and 77% by EIA. The median fraction of total ER present as ERn was 63%. PR levels correlated positively with ERn concentrations (r: 0.73). We explore possible reasons why greater concentrations of ERc are determined by estradiol binding than by the ER-EIA kit...

    Background: Loss of E-cadherin is a critical step for development and progression of malignant tumors. CD10; a marker of non-neoplastic and neoplastic endometrial stroma, is associated with aggressiveness of many epithelial malignancies. Aims: To evaluate expression and correlation of E-cadherin and CD10 in endometrial lesions and their possible role in differentiating atypical endometrial hyperplasia from endometrial carcinoma. The association of E-cadherin and CD10 expression with clinico-pathological parameters of endometrial carcinoma was also investigated. Materials and methods: Fifty four cases including 28 endometrial carcinomas; 19 endometrial hyperplasia and 7 cases of normal endometrial changes were enrolled for this study. The expression of E-cadherin and CD10 was evaluated by immunohistochemistry using the streptavidin–biotin technique. Results: There was a strong association between malignant change of endometrial glands and membrano- cytoplasmic localization of E-cadherin (p< 0.001). Expression of E-cadherin but not CD10 was significantly higher in endometrial carcinomas compared to atypical endometrial hyperplasia (p < 0.01). Expression of E-cadherin was not associated with CD10 expression in different endometrial lesions. High grade tumors expressed low levels of both E-cadherin (p<0.01) and CD10 (p < 0.05) and serous endometrial carcinoma had low E-cadherin and CD10 expression compared to endometrioid carcinoma (p< 0.01 and <0.05, respectively). Expression of both molecules showed no association with depth of tumor invasion or FIGO stage. Tumors with lower E-cadherin or CD10 expression had higher rates of vascular tumor emboli (p< 0.01 and <0.07, respectively). Conclusions: Although expression of E-cadherin and CD10 in endometrial lesions was not correlated, reduced expression of both molecules could be critical for progression of endometrial carcinoma.

    The present study was designed to determine the accuracy of Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) in evaluating the extent of the tumor in 36 patients with endometrial carcinoma. The CT and MRI findings were compared with the microscopic pathologic characteristics in all cases. Linear regression analysis for measurements of residual normal myometrium revealed significant positive correlations (p<0.001) between MRI (r=0.861) and CT (r=0.826) findings and pathologic evaluation. Thirty-six patients were divided into two groups according to our previous CT and MRI criteria: the superficial myometrial invasion group and advanced tumor group. In MRI findings, higher incidences of deep (≥1/2) myometrial invasion (p<0.001), vessel permeation (p<0.05) and cervical involvement (p<0.05) were observed in the advanced group. In CT findings, deep myometrial invasion (p<0.001) was observed in the advanced group. The incidence of extrauterine extension of the tumor did not differ significantly between CT and MRI findings. The accuracy figures for cervical involvement evaluated by CT and MRI were 83%, and 86%, respectively. In four of 6 patients, in whom an intact Junctional zone (j-zone) was detected by MRI, the tumor was localized in the endometrium. The remaining 2 patients had only superficial myometrial invasion histologically. In all 16 patients, in whom the j-zone was interrupted in MRI findings, myometrial invasion was confirmed pathologically. In conclusion, the present study demonstrates that the overall accuracy of MRI staging in patients with endometrial carcinoma is 61.1%, and CT, as well as MRI, is effective preoperatively in evaluating the extent of the tumor.

    Inherited ABO blood groups have been shown to play possible contributions in the pathogenesis of various gynecologic and non-gynecologic carcinomas. With regard to gynecologic carcinomas, there is a confined number of studies that explored the relationship between ABO blood group and endometrial carcinoma (EC) in the PubMed-indexed literature. To the best of our knowledge, no such study has ever been conducted in Saudi Arabia. Our study has two objectives: (I) to determine the prevalence of ABO blood groups among Saudi patients with EC, and (II) to explore the relationship between ABO blood group and several clinico-pathological prognostic parameters (namely: menopausal status [age], body mass index [BMI], tumor grade, FIGO [Fédération Internationale de Gynécologie et d'Obstétrique] stage and recurrence) in Saudi patients with EC. A retrospective cross-sectional study from 01-January-2010 to 31-July-2014 was conducted at King Faisal Specialist Hospital & Research Centre, Riyadh, Saudi Arabia - a referral tertiary healthcare institute. One-hundred and fourteen patients (n=114) were included in the study. Clinico-pathological data were extrapolated from medical records, and their association with ABO blood groups were evaluated. Categorical data were presented as number of cases (n) and percentages (%). Two-tailed Chi-square test was used for univariate analysis. For all purposes, p values 28 kg/m 2 (84.2%), diagnosed with early FIGO stage I-II (76.3%) and developed no recurrence (86.8%). The frequencies of ABO blood group types A, B, AB, and O were 28.1%, 12.3%, 3.5% and 56.1%, respectively. When ABO blood groups were analyzed as four different types (A, B, AB and O), O-type was the most common ABO blood group in pre- and post-menopausal EC patients (43.8% and 58.2%, respectively; p=0.14). There were no statistically significant correlations between ABO blood groups and all the examined clinico-pathological factors. Moreover, when ABO blood groups were

    The in vitro microculture kinetic (MiCK) apoptosis assay has been used to predict single or combination chemotherapy response in leukemia patients. This feasibility study addressed MiCK in endometrial cancer specimens. Endometrial cancer specimens from total abdominal hysterectomies were processed at a central laboratory. Single cell suspensions of viable endometrial cancer cells were plated in individual wells. Single and combination regimens were tested: combinations of doxorubicin, cisplatin, and paclitaxel and carboplatin and paclitaxel (Gynecologic Oncology Group [GOG] 209 endometrial cancer phase III trial arms) as well as single agent testing with paclitaxel, carboplatin, doxorubicin, cisplatin, ifosfamide, and vincristine (active agents in GOG trials). Apoptosis was measured continuously over 48 hours. Fifteen of nineteen patients had successful assays. The highest mean chemo sensitivity was noted in the combination of cisplatin, doxorubicin, and paclitaxel with lower mean chemosensitivity for carboplatin and paclitaxel. Combination chemotherapy had higher chemosensitivity than single drug chemotherapy. However, in 25% of patients a single drug had higher chemosensitivity than combination chemotherapy. As single agents, ifosfamide, cisplatin, and paclitaxel had the highest kinetic unit values. Using a panel of agents simulating clinical dose regimens, the MiCK assay was feasible in evaluating in vitro chemosensitivity of endometrial cancer. MiCK assay results correlated with GOG clinical trial results. However, 25% of patients might be best treated with single agent chemotherapy selected by MiCK. Ifosfamide, cisplatin, and paclitaxel appear to have high activity as single agents. MiCK may be useful in future new drug testing and individualizing endometrial cancer patient's chemotherapy management.

    Our objective was to identify the most accurate method of endometrial sampling for the diagnosis of complex atypical hyperplasia (CAH), and the related risk of underestimation of endometrial cancer. We conducted a systematic literature search in PubMed and EMBASE (January 1999-September 2013) to identify all registered articles on this subject. Studies were selected with a 2-step method. First, titles and abstracts were analyzed by 2 reviewers, and 69 relevant articles were selected for full reading. Then, the full articles were evaluated to determine whether full inclusion criteria were met. We selected 27 studies, taking into consideration the comparison between histology of endometrial hyperplasia obtained by diagnostic tests of interest (uterine curettage, hysteroscopically guided biopsy, or hysteroscopic endometrial resection) and subsequent results of hysterectomy. Analysis of the studies reviewed focused on 1106 patients with a preoperative diagnosis of atypical endometrial hyperplasia. The mean risk of finding endometrial cancer at hysterectomy after atypical endometrial hyperplasia diagnosed by uterine curettage was 32.7% (95% confidence interval [CI], 26.2-39.9), with a risk of 45.3% (95% CI, 32.8-58.5) after hysteroscopically guided biopsy and 5.8% (95% CI, 0.8-31.7) after hysteroscopic resection. In total, the risk of underestimation of endometrial cancer reaches a very high rate in patients with CAH using the classic method of evaluation (i.e., uterine curettage or hysteroscopically guided biopsy). This rate of underdiagnosed endometrial cancer leads to the risk of inappropriate surgical procedures (31.7% of tubal conservation in the data available and no abdominal exploration in 24.6% of the cases). Hysteroscopic resection seems to reduce the risk of underdiagnosed endometrial cancer. Copyright © 2016 AAGL. Published by Elsevier Inc. All rights reserved.

    Purpose: This retrospective study was designed to evaluate the role of adjuvant radiotherapy for surgically treated endometrial carcinoma. Patients and methods: From 1980 through 1988, 541 patients were treated with either intravaginal cuff irradiation with a high-dose-rate (HDR) Iridium-192 remote afterloading technique (n=294) or with combined HDR-brachytherapy and additional external pelvic irradiation to 54 Gy (n=247) after surgery for endometrical cancer. Afterloading irradiation was administered in 4 fractions 4 to 6 weeks after surgery. A dose of 30 Gy was delivered at a depth of 0,5 cm from the vaginal mucosa. Results: Patients with HDR-brachytherapy alone showed a 5-year survival of 94.3% for Stage I and 73.6% for Stage II (p=0.0007). Patients who received both brachytherapy and additional pelvic irradiation had a 5-year survival of 94.1% for Stage I, 81.1% for Stage II, 70.4% for Stage III and 46.9% for Stage IV (p=0.0001). The main predictors for survival in a multivariate analysis were stage and grading. Patients with combined readiotherapy had a local recurrence rate of 3.2%, whereas patients with brachytherapy alone who were better selected and had more favorable prognostic factors showed a recurrence rate of 2%. Low-risk patients (Stage I, Grade 1, low infiltration) in the HDR-brachytherapy group had 6 relapses, mainly caused by insufficient treatment on the basis of papillary histology. High-risk patients with poorly differential tumors, which infiltrate more than half the myometrial wall might benefit from additional external radiotherapy in terms of reduction of local recurrence and better survival. Five-year actuarial survival rate was 93.6% after combined radiotherapy vs 86.7% after brachytherapy alone. Complications were graded according to the RTOG scoring system. Severe late complications were fistulas of bladder and/or bowel, which occurred in 2.8% in the combined radiotherapy group, and 0.7% in the HDR brachytherapy group. (orig.) [de

    The epithelial-mesenchymal transition is the key process driving cancer metastasis. MicroRNA-194 inhibits epithelial-mesenchymal transition in several cancers and its downregulation indicates a poor prognosis in human endometrial carcinoma. Self-renewal factor Sox3 induces epithelial-mesenchymal transition at gastrulation and is also involved epithelial-mesenchymal transition in several cancers. We intended to determine the roles of Sox3 in inducing epithelial-mesenchymal transition in endometrial cancer stem cells and the possible role of microRNA-194 in controlling Sox3 expression. Firstly, we found that Sox3 and microRNA-194 expressions were associated with the status of endometrial cancer stem cells in a panel of endometrial carcinoma tissue, the CD133+ cell was higher in tumorsphere than in differentiated cells, and overexpression of microRNA-194 would decrease CD133+ cell expression. Silencing of Sox3 in endometrial cancer stem cell upregulated the epithelial marker E-cadherin, downregulated the mesenchymal marker vimentin, and significantly reduced cell invasion in vitro; overexpression of Sox3 reversed these phenotypes. Furthermore, we discovered that the expression of Sox3 was suppressed by microRNA-194 through direct binding to the Sox3 3'-untranslated region. Ectopic expression of microRNA-194 in endometrial cancer stem cells induced a mesenchymal-epithelial transition by restoring E-cadherin expression, decreasing vimentin expression, and inhibiting cell invasion in vitro. Moreover, overexpression of microRNA-194 inhibited endometrial cancer stem cell invasion or metastasis in vivo by injection of adenovirus microRNA-194. These findings demonstrate the novel mechanism by which Sox3 contributes to endometrial cancer stem cell invasion and suggest that repression of Sox3 by microRNA-194 may have therapeutic potential to suppress endometrial carcinoma metastasis. The cancer stem cell marker, CD133, might be the surface marker of endometrial cancer stem

    To investigate the tumorigenesis of mutant [12Asp]-K-ras in endometrial carcinoma and its relationship with ER. We constructed pcDI-[12Asp]K-ras4B by inserting full-length [12Asp]K-ras4B from human endometrial carcinoma Hec-1A cells, into pcDI vector. Cell proliferation of NIH3T3 after transfection with pcDI-[12Asp]K-ras4B was measured by MTT assay. The cell transformation was determined by colony formation and tumor nodule development. [12Asp]-K-ras4B-NIH3T3 cells were transfected with constitutively active pCMV-RafCAAX and dominant-negative pCMV-RafS621A. Cell growth was measured by MTT assay and [3H]thymidine incorporation. After transfected with pcDI-[12Asp]K-ras4B or pCMV-RafS621A, the cells were harvested for Western blot and reporter assay to determine the expression and transcriptional activity of ERalpha and ERbeta, respectively. [12Asp]-K-ras4B enhanced NIH3T3 cells proliferation after 48 h post-transfection (P ras4B-NIH3T3 cells (13.48%) than pcDI-NIH3T3 (4.26%) or untreated NIH3T3 (2.33%). The pcDI-[12Asp]-K-ras4B-NIH3T3 cells injected to the nude mice Balb/C developed tumor nodules with poor-differentiated cells after 12 days. An increase of ERalpha and ERbeta was observed in pcDI-[12Asp]-K-ras4B-NIH3T3 cells. RafS621A downregulated ERalpha and ERbeta expression. Estrogen induced the ER transcriptional activity by 5-fold in pcDI-NIH3T3 cells, 13-fold in pcDI-[12Asp]K-ras4B-NIH3T3 and 19-fold in HEC-1A. RafS621A suppressed the ER transcriptional activity. K-ras mutation induces tumorigenesis in endometrium, and this malignant transformation involves Raf signaling pathway and ER.

    Purpose/Objective(s): To determine the impact of adjuvant radiation treatment (RT) on recurrence-free survival (RFS), disease-specific survival (DSS), and overall survival (OS) in patients with high-risk 2009 International Federation of Gynecology and Obstetrics stage I-II endometrial carcinoma. Methods and Materials: We identified 382 patients with high-risk EC who underwent hysterectomy. RFS, DSS, and OS were calculated from the date of hysterectomy by use of the Kaplan-Meier method. Cox regression modeling was used to explore the risks associated with various factors on survival endpoints. Results: The median follow-up time for the study cohort was 5.4 years. The median age was 71 years. All patients underwent hysterectomy and salpingo-oophorectomy, 93% had peritoneal cytology, and 85% underwent lymphadenectomy. Patients with endometrioid histology constituted 72% of the study cohort, serous in 16%, clear cell in 7%, and mixed histology in 4%. Twenty-three percent of patients had stage II disease. Adjuvant management included RT alone in 220 patients (57%), chemotherapy alone in 25 patients (7%), and chemoradiation therapy in 27 patients (7%); 110 patients (29%) were treated with close surveillance. The 5-year RFS, DSS, and OS were 76%, 88%, and 73%, respectively. On multivariate analysis, adjuvant RT was a significant predictor of RFS (P<.001) DSS (P<.001), and OS (P=.017). Lymphovascular space involvement was a significant predictor of RFS and DSS (P<.001). High tumor grade was a significant predictor for RFS (P=.038) and DSS (P=.025). Involvement of the lower uterine segment was also a predictor of RFS (P=.049). Age at diagnosis and lymphovascular space involvement were significant predictors of OS: P<.001 and P=.002, respectively. Conclusion: In the treatment of patients with high-risk features, our study suggests that adjuvant RT significantly improves recurrence-free, disease-specific, and overall survival in patients with early-stage endometrial carcinoma

    Endometrial biopsy (EMBx) and colonoscopy performed under the same sedation is termed combined screening and has been shown to be feasible and to provide a less painful and more satisfactory experience for women with Lynch syndrome (LS). However, clinical results of these screening efforts have not been reported. The purpose of this study was to evaluate the long-term clinical outcomes and patient compliance with serial screenings over the last 10.5 years. We retrospectively analyzed the data for 55 women with LS who underwent combined screening every 1-2 years between 2002 and 2013. Colonoscopy and endometrial biopsy were performed by a gastroenterologist and a gynecologist, with the patient under conscious sedation. Out of 111 screening visits in these 55 patients, endometrial biopsies detected one simple hyperplasia, three complex hyperplasia, and one endometrioid adenocarcinoma (FIGO Stage 1A). Seventy-one colorectal polyps were removed in 29 patients, of which 29 were tubular adenomas. EMBx in our study detected endometrial cancer in 0.9% (1/111) of surveillance visits, and premalignant hyperplasia in 3.6% (4/111) of screening visits. No interval endometrial or colorectal cancers were detected. Combined screening under sedation is feasible and less painful than EMBx alone. Our endometrial pathology detection rates were comparable to yearly screening studies. Our results indicate that screening of asymptomatic LS women with EMBx every 1-2 years, rather than annually, is effective in the early detection of (pre)cancerous lesions, leading to their prompt definitive management, and potential reduction in endometrial cancer.

    Current guidelines on germline mutation testing for patients suspected of having Lynch syndrome are not entirely clear in patients with tumors demonstrating isolated loss of PMS2 immunohistochemical expression. We analyzed the clinical and pathologic features of patients with tumors demonstrating isolated loss of PMS2 expression in an attempt to (1) determine the frequency of germline MLH1 and PMS2 mutations and (2) correlate mismatch-repair protein immunohistochemistry and tumor histology with germline mutation results. A total of 3213 consecutive colorectal carcinomas and 215 consecutive endometrial carcinomas were prospectively analyzed for DNA mismatch-repair protein expression by immunohistochemistry. In total, 32 tumors from 31 patients demonstrated isolated loss of PMS2 immunohistochemical expression, including 16 colorectal carcinomas and 16 endometrial carcinomas. Microsatellite instability (MSI) polymerase chain reaction was performed in 29 tumors from 28 patients with the following results: 28 tumors demonstrated high-level MSI, and 1 tumor demonstrated low-level MSI. Twenty of 31 (65%) patients in the study group had tumors demonstrating histopathology associated with high-level MSI. Seventeen patients underwent germline mutation analysis with the following results: 24% with MLH1 mutations, 35% with PMS2 mutations, 12% with PMS2 variants of undetermined significance, and 29% with no mutations in either MLH1 or PMS2. Three of the 4 patients with MLH1 germline mutations had a mutation that results in decreased stability and quantity of the MLH1 protein that compromises the MLH1-PMS2 protein complex, helping to explain the presence of immunogenic but functionally inactive MLH1 protein within the tumor. The high frequency of MLH1 germline mutations identified in our study has important implications for testing strategies in patients suspected of having Lynch syndrome and indicates that patients with tumors demonstrating isolated loss of PMS2 expression

    We explored the role of histogram analysis of apparent diffusion coefficient (ADC) maps for discriminating uterine carcinosarcoma and endometrial carcinoma. We retrospectively evaluated findings in 13 patients with uterine carcinosarcoma and 50 patients with endometrial carcinoma who underwent diffusion-weighted imaging (b = 0, 500, 1000 s/mm(2) ) at 3T with acquisition of corresponding ADC maps. We derived histogram data from regions of interest drawn on all slices of the ADC maps in which tumor was visualized, excluding areas of necrosis and hemorrhage in the tumor. We used the Mann-Whitney test to evaluate the capacity of histogram parameters (mean ADC value, 5th to 95th percentiles, skewness, kurtosis) to discriminate uterine carcinosarcoma and endometrial carcinoma and analyzed the receiver operating characteristic (ROC) curve to determine the optimum threshold value for each parameter and its corresponding sensitivity and specificity. Carcinosarcomas demonstrated significantly higher mean vales of ADC, 95th, 90th, 75th, 50th, 25th percentiles and kurtosis than endometrial carcinomas (P Histogram analysis of ADC maps might be helpful for discriminating uterine carcinosarcomas and endometrial carcinomas.

    A high dose-rate (cobalt-60) afterloading technique was used for postoperative vaginal irradiation in a series of 404 women with endometrial carcinoma stage I. The total recurrence rate was 3.7% with 0.7% vaginal lesions. The crude 5-year survival rate for the complete series was 91.8% compared to 13.3% for those with recurrences. Depth of myometrical infiltration (>1/3 of the uterine wall) and nuclear grade were the most important prognostic factors. Clinically significant late radiation reactions (bladder and/or rectum) were recorded in 6.9%. The absorbed dose per fraction and the size of the treatment volume were significantly related to the occurrence of both early and late radiation reactions. Vaginal shortening was closely related to the dose per fraction, length of the referce isodose and the applicator diameter. The shape of the vaginal applicator versus the isodose contours and the importance of the source train geometry and relative activity for absorbed dose inhomogeneitis within the treatment volume are discussed. Cumulative radiation effect (CRE) and linear-quadratic (LQ) calculations have been performed and related to tissue reactions within the target volume and in the risk organs. An alpha-beta quotient of 8.8 Gy for vaginal shrinkage effect and 2.0 Gy for late rectal complications are suggested on the basis of calculations using a maximum likelihood method for quantal radiation data.

    A high dose rate ( 60 Co) afterloading technique was used for postoperative prophylactic vaginal irradiation in a series of 404 women with endometrial carcinoma Stage I. The total recurrence rate was 3.7% with 0.7% vaginal deposits. The crude 5-year survival rate for the complete series was 91.8% compared to 13.3% for those with recurrences. Depth of myometrial infiltration (greater than 1/3 of the uterine wall) and nuclear grade were the most important prognostic factors. Clinically significant late radiation reactions (bladder and/or rectum) were recorded in 6.9%. Dose per fraction and the size of the target volume were highly significantly related to the occurrence of both early and late radiation reactions. Vaginal shortening is closely related to the dose per fraction, length of the reference isodose, and the applicator diameter. The shape of the vaginal applicator versus the isodoses and the importance of the source train geometry and relative activity for dose gradient inhomogeneities within the target volume are discussed. Cumulative radiation effect (CRE) and linear-quadratic (LQ) calculations have been performed and related to tissue reactions within the target volume and in the risk organs.

    To assess the efficacy and pathological change of fertility-sparing treatment with progestin for endometrial carcinoma (EC) of stage I a and complex atypical hyperplasia (CAH) and to observe the prognosis of the treatment. Nine EC patients of stage I a and 21 CAH patients aged under 40 years who desired childbearing and retaining their fertility were enrolled into this study. All patients were given a daily oral high-dose of progestin with duration of treatment ranging from 6 to 9 months. Diagnostic curettage was performed every 3 months as a modality for seeing the histologic change of neoplastic tissues and endometrial tissue. A careful and long- term follow- up is necessary for patients with complete response (CR). During the first period of fertility-sparing management, according to histologic change, 5 EC patients and 18 CAH patients showed CR with no evidence of endometrial adenocarcinoma or hyperplasia, 2 EC patients and 2 CAH patients showed partial response with a regression to complex or simple hyperplasia without atypia, 2 EC patients and 1 CAH patient showed stable disease or progressive disease. Accordingly, a total of 26 patients showed CR (26 of 30 patients). The median time to CR was 6 months (range, 3 to 21 months) of progestin treatment. The median follow-up time was 55.5 months (range, 24 to 104 months) and all patients were alive. During follow-up, among the 26 patients with CR, 3 of 6 EC patients achieved CR recurred disease after a median time interval of 10 months (range, 6 to 51 months), 7 of 20 CAH patients achieved CR had recurrent disease after a median time interval of 12 months (range, 6 to 55 months). Four of 7 CAH with recurrent disease achieved CR to progestin re-treatment. Eight of 26 patients achieved CR continued a further 3 or 6 months of consolidation therapy, 3 of them had recurrent disease, the remaining 18 stopped progesterone treatment after CR and 7 patients had recurrent disease; there was no significant statistical

    Full Text Available Background: Cell proliferation and motility require actin reorganization, which is under control of various signalling pathways including ras-related C3 botulinum toxin substrate 1 (RAC1, p21 protein-activated kinase 1 (PAK1 and actin related protein 2 (ARP2. Tumour cell proliferation is modified by 1α,25-Dihydroxy-Vitamin D3 (1α,25(OH2D3, a steroid hormone predominantly known for its role in calcium and phosphorus metabolism. The present study explored whether 1α,25(OH2D3 modifies actin cytoskeleton in Ishikawa cells, a well differentiated endometrial carcinoma cell line. Methods: To this end, actin cytoskeleton was visualized by confocal microscopy. Globular over filamentous actin ratio was determined utilizing Western blotting and flow cytometry, transcript levels by qRT-PCR and protein abundance by immunoblotting. Results: A 24 hour treatment with 1α,25(OH2D3 (100 nM significantly decreased RAC1 and PAK1 transcript levels and activity, decreased ARP2 protein levels and depolymerized actin. The effect of 1α,25(OH2D3 on actin polymerization was mimicked by pharmacological inhibition of RAC1 and PAK1. Conclusions: 1α,25(OH2D3 leads to disruption of RAC1 and PAK1 activity with subsequent actin depolymerization of endometrial carcinoma cells.

    At time of presentation, fewer than 10% of patients have metastatic breast cancer. The most common sites of metastasis in order of frequency are bone, lung, pleura, soft tissue, and liver. Breast cancer metastasis to the uterus or gallbladder is rare and has infrequently been reported in the English literature. A 47 year old female with a recent history of thrombocytopenia presented with abnormal vaginal bleeding. Pelvic ultrasound revealed multiple uterine fibroids and endometrial curettings revealed cells consistent with lobular carcinoma of the breast. Breast examination revealed edema and induration of the lower half of the right breast. Biopsy of the right breast revealed invasive lobular carcinoma. Bone marrow aspiration obtained at a previous outpatient visit revealed extensive involvement by metastatic breast carcinoma. Shortly after discharge, the patient presented with acute cholecystitis and underwent cholecystectomy. Microscopic examination of the gallbladder revealed metastatic infiltrating lobular carcinoma. The final diagnosis was invasive lobular carcinoma of the right breast with metastasis to the bone marrow, endometrium, gallbladder, regional lymph nodes, and peritoneum. The growth pattern of invasive lobular carcinoma of the breast is unique and poses a challenge in diagnosing the cancer at an early stage. Unlike other types of breast cancer, it tends to metastasize more to the peritoneum, ovary, and gastrointestinal tract. Metastasis to the endometrium or gallbladder is rare. Metastatic spread should be considered in the differential diagnosis of patients with invasive lobular breast carcinoma presenting with abnormal vaginal bleeding or acute cholecystitis.

    Purpose: To compare the outcomes for endometrial carcinoma patients treated with either high-dose-rate (HDR) or low-dose-rate (LDR) brachytherapy. Methods and Materials: This study included 1,179 patients divided into LDR (1,004) and HDR groups (175). Patients with International Federation of Gynecology and Obstetrics (FIGO) surgical Stages I-III were included. All patients were treated with postoperative irradiation. In the LDR group, the postoperative dose applied to the vaginal cuff was 60-70 Gy surface doses to the vaginal mucosa. The HDR brachytherapy prescription was 6 fractions of 2 Gy each to a depth of 0.5 cm from the surface of the vaginal mucosa. Overall survival, disease-free survival, local control, and complications were endpoints. Results: For all stages combined, the overall survival, disease-free survival, and local control at 5 years in the LDR group were 70%, 69%, and 81%, respectively. For all stages combined, the overall survival, disease-free survival, and local control at 5 years in the HDR group were 68%, 62%, and 78%, respectively. There were no significant differences in early or late Grade III and IV complications in the HDR or LDR groups. Conclusion: Survival outcomes, pelvic tumor control, and Grade III and IV complications were not significantly different in the LDR brachytherapy group compared with the HDR group

    To evaluate MR capacity in assessing deep myometrial and cervical infiltrations in cases of endometrial carcinoma. A series of 30 consecutively diagnosed endometrial cancer patients was pre-surgically evaluated by means of magnetic resonance (MR). TSE-T2 sequences with fat saturation and dynamic FFe sequence were used after gadolinium administration. A correlation with post-surgical histological stating was made. There were then determined sensitivity (S), specificity (SP), positive predictive value (PPV) and negative predictive value (NPV) for the deep myometrial infiltration and cervical invasion. Cases of overestimation and underestimation were analyzed. Values obtained for myometrium and cervix were, respectively, S of 67% and 63%, SP of 89% and 91%, PPV of 80% and 71% and NPV of 80% and 87%. Two cases each were over valued for myometrial infiltration and cervix: four cases and 3 cases, respectively, were undervalues. MR stating in cases of endometrial carcinoma is a highly reliable diagnostic technique, but it does present certain limitations. (Author) 19 refs.

    Endometrial neoplasia is the most common malignant tumor of female genital system in developed countries. The incidence of endometrial cancer has increased in the last years and despite advances in diagnosis and treatment, the death rates have steadily been increasing over the past 20 years. Therefore aspects of endometrial cancer development, pathogenesis and effective treatment is especially urgent to this day, as much of the risk for endometrial cancer development is influenced by the environment and lifestyle. Endometrial stem cells take the special place among somatic stem cells of female reproductive system-the detection of them and identification of their location in the complex cellular hierarchy still remains challenging. Further study of endometrial stem cells will clarify their role in gynecologic pathologies associated with hyper-proliferative states of endometrium. The aim of our study was to explore the specificities of endometrial proliferative/stem cell index distribution under endometrioid carcinoma of different grade of malignancy. The study represents a retrospective research. The coded and depersonalized material data from Acad. N. Kipshidze Central University Clinic was used in the study. 3 study groups - 1st study group "Endometrioid Carcinoma Grade 1" (14 cases), 2nd study group "Endometrioid Carcinoma Grade 2" (23 cases) and 3rd study group "Endometrioid Carcinoma Grade 3" were selected from routine histopathology tissue specimens of uterus. Hematoxilyn-eosin technology and immunohistochemistry with proliferation marker ki67 and stem cell marker CD146 was performed. The proliferative/stem cell index was calculated by the ratio of Ki67-positive cell percentage value divided by CD146-positive cell percentage value. The study showed that in the 1st study group labeled as "Endometrioid Carcinoma Grade 1", the proliferative/stem cell index ranges between 21.7 and 25.5. Its mean average value in the age distribution subgroups accounts for: 1

    Purpose. The depth of myometrial invasion by endometrial carcinoma strongly affects the incidence of metastasis to regional nodes and influences the surgical strategies. The aim of this paper is to compare the results of FSE T2-w and Gadolinium-enhanced FMPSGR MR sequences in assessing the depth of myometrial invasion by endometrial cancer. Materials and methods. Forty-five women with histopathologically-proven endometrial carcinoma underwent preoperative MRI. Axial SE TI w, axial, sagittal and para-coronal FSE T2w and para-coronal Gadolinium enhanced FMPSGR sequences were performed using a high field strength magnet (1.5T). Within one month of MR all patients underwent hysterectomy, and anatomical evaluation of the surgical specimen was done sectioning the uterus along the short axis. Based upon the results of the histological evaluation the results of the FSE T2w and Gadolinium-enhanced sequences were compared and the statistical difference between the results obtained was statistically evaluated. Results. The histological evaluation showed intra mucosal neoplasm in 11 patients, myometrial infiltration less than 50% in 31 patients, myometrial infiltration more than 50% in 12 patients and transmural cancer 1 patient. Statistical evaluation showed that the FSE T2w sequence had a global sensitivity and specificity of 80.6% and 87.6%, respectively, with a mean Negative Predictive Value of 92.6% and a mean Positive Predictive Value of 86%. Gadolinium-enhanced FMPSPGR sequence had a global sensitivity and specificity of 90.6% and 93.3%, respectively, with a mean Negative Predictive Value of 96,3% and a mean Positive Predictive Value of 88%. The staging accuracy (χ 2 test) on FMPSPGR images (95%) was higher than that on FSE T2w images (78%). Conclusions. In our experience Gadolinium-enhanced dynamic sequences increase the accuracy of MR imaging in diagnosing the depth of myometrial invasion. In particular they improve the visualisation of the inner myometrium, the so

    A total of 91 patients with stage 1 endometrial adenocarcinoma who were referred for radiation prior to hysterectomy were randomly allocated to receive either intracavitary or external beam irradiation. Total abdominal hysterectomy was done 4--8 weeks later. The 53 patients who received intracavitary irradiation had an actuarial 5 year disease-free survival rate of 75 percent; the survival rate of the 38 patients in the external beam group was 48 percent. Nine patients in the external beam group had recurrence or metastases compared to two in the intracavitary group. These recurrences were predominantly pelvic. Complications were also more frequent in the external beam group. These results demonstrate that intracavitary radiation is superior to external beam radiation using the regimens described

    Full Text Available Background. Bardet-Biedl Syndrome (BBS is a rare genetic condition characterized by cognitive impairment, dysmorphism, central obesity, and diabetes mellitus, among other abnormalities. Although some of these characteristics are known independent risk factors for endometrial cancer and its precursors, the association between BBS and endometrial cancer is underreported. Case. We present the case of a 26-year-old patient with BBS and clinical signs of hyperestrogenism who presented with abnormal uterine bleeding and was diagnosed with endometrioid adenocarcinoma. She ultimately underwent definitive surgical treatment with hysterectomy and bilateral salpingectomy. Conclusions. This is one of only a few reports in the literature describing the association of BBS and endometrioid endometrial adenocarcinoma. Given the association of BBS with risk factors for hyperestrogenism such as truncal obesity, hyperinsulinemia, and ovulatory dysfunction, providers should have increased suspicion for endometrial cancer in young patients with BBS and abnormal uterine bleeding.

    Full Text Available Background: Post-menopausal hemorrhage is one of the most common complains in gynecologic clinics. More than 60% of these cases have abnormal findings in diagnostic work ups. There is contraversy about the best diagnostic method for evaluating post-menopausal hemorrhage. The aim of this study was to evaluate the results of Trans-Vaginal Ultrasonography and compare its result to ones derived from direct endometrial biopsy and Hysteroscopy findings.Methods: In a cross-sectional study, menopausal women who attended the outpatient clinic of Arash Hospital, Tehran University of medical Sciences, from April 2005 to March 2006 with the complain of hemorrhage were evaluated. In all of these patients, after getting informed consent, Trans-Vaginal Ultrasonography, Dilatation and Curettage and Hysteroscopy were performed.Results: The total number of 90 women was recruited to the study with the age range of 41-80 years. The mean age of participants was 53.84 ± 6 years and 4.3 ± 5.1 years had passed from their menopause. The mean thickness of endometrium, measured by Trans Vaginal ultrasonography was 6.25 ± 3.7 millimeter. In the biopsy derived specimens, the most finding pathological presentation was atrophy (48.9% and the Proliferative endometrium had the second prevalence (36.7%. Atrophy (44.4% and Proliferative endometrium (33.3% were the most prevalent finding in Hysteroscopy. There was a significant difference in endometrial thickness between groups of different pathological findings. A significant difference in endometrial thickness was also seen between groups with different Hysteroscopic finding. By grouping the data according to endometrial thickness, it became evident that endometrial thickness can predict the outcome of endometrial biopsy and Hysteroscopic finding efficiently. We used ROC curves to find the best grouping threshold for endometrial thickness to achieve the best sensitivity and specificity.Conclusion: Measuring the endometrial

    Thickened or indistinct junctional zone (JZ) is a problematic finding in staging endometrial carcinoma. We studied the incidence, pathological cause of this condition correlated to microcirculation, and the utility of dynamic contrast MRI for differential diagnosis. T2-weighted images were analyzed in 119 cases with endometrial carcinoma. The enhancement of the JZ during the dynamic contrast MRI, histopathological causes, and the density of arterioles in the JZ were retrospectively analyzed in cases with thickened or indistinct JZ. The MRI histopathological correlation of all 31 patients with a thickened or indistinct JZ were analyzed, in which it was corresponded to myometrial cancer invasion only in 22%. The sensitivity of a poor early enhancement pattern on dynamic study for detecting myometrial invasion was 71.4%, the specificity was 100%, and the overall accuracy was 92.5%. Although only weak relationship between the contrast enhancement and the arteriole density was revealed, the arteriole density within the JZ with cancer invasion was significantly decreased. Poor enhancement of JZ in early dynamic phase was correlated with the decreased density of arterioles within the myometrium which was invaded by endometrial carcinoma. Dynamic contrast study should be performed in staging endometrial carcinoma especially when JZ was thickened or indistinct. (orig.)

    Full Text Available We examined the association between HNF1B variants identified in a recent genome-wide association study and endometrial cancer in two large case-control studies nested in prospective cohorts: the Multiethnic Cohort Study (MEC and the Women's Health Initiative (WHI as part of the Population Architecture using Genomics and Epidemiology (PAGE study. A total of 1,357 incident cases of invasive endometrial cancer and 7,609 controls were included in the analysis (MEC: 426 cases/3,854 controls; WHI: 931 cases/3,755 controls. The majority of women in the WHI were European American, while the MEC included sizable numbers of African Americans, Japanese and Latinos. We estimated the odds ratios (ORs per allele and 95% confidence intervals (CIs of each SNP using unconditional logistic regression adjusting for age, body mass index, and four principal components of ancestry informative markers. The combined ORs were estimated using fixed effect models. Rs4430796 and rs7501939 were associated with endometrial cancer risk in MEC and WHI with no heterogeneity observed across racial/ethnic groups (P ≥ 0.21 or between studies (P ≥ 0.70. The OR(per allele was 0.82 (95% CI: 0.75, 0.89; P = 5.63 × 10(-6 for rs4430796 (G allele and 0.79 (95% CI: 0.73, 0.87; P = 3.77 × 10(-7 for rs7501939 (A allele. The associations with the risk of Type I and Type II tumors were similar (P ≥ 0.19. Adjustment for additional endometrial cancer risk factors such as parity, oral contraceptive use, menopausal hormone use, and smoking status had little effect on the results. In conclusion, HNF1B SNPs are associated with risk of endometrial cancer and that the associated relative risks are similar for Type I and Type II tumors.

    Full Text Available The aqueous extracts of the leaves and fruit of Camptotheca acuminata have long been used in traditional Chinese medicine (TCM for treating cancer patients. The chemotherapeutic drug, camptothecin (CPT, and related analogs were first isolated from C. acuminata in the 1970s. Although the antitumor effects of CPT have been characterized in recent years, the antitumor effects of aqueous extracts of C. acuminata have not been clarified. The aims of our current study were to determine the tumor-suppression efficiency of an aqueous extract of the fruit of C. acuminata (AE-CA in the human endometrial carcinoma cell lines, HEC-1A, HEC-1B, and KLE, and compare its antitumor effects with those of CPT. Cell viability assays indicated that a dosage of AE-CA containing 0.28 mg/mL of CPT demonstrated enhanced cytotoxicity, compared with CPT treatment. The effects of AE-CA on the induction of cell cycle arrest, the accumulation of cyclin-A2 and -B1, and the activation of caspase-3 and caspase-7 were similar to those of CPT. Furthermore, AE-CA exhibited a synergistic effect on the cytotoxicity of cisplatin in HEC-1A and HEC-1B cells. These results indicated that AE-CA is a potent antitumor agent and can be combined with cisplatin for the treatment of human endometrial cancer.

    Categorization and risk stratification of endometrial carcinomas is inadequate; histomorphologic assessment shows considerable interobserver variability, and risk of metastases and recurrence can only be derived after surgical staging. We have developed a Proactive Molecular Risk classification tool for Endometrial cancers (ProMisE) that identifies four distinct prognostic subgroups. Our objective was to assess whether molecular classification could be performed on diagnostic endometrial specimens obtained prior to surgical staging and its concordance with molecular classification performed on the subsequent hysterectomy specimen. Sequencing of tumors for exonuclease domain mutations (EDMs) in POLE and immunohistochemistry for mismatch repair (MMR) proteins and p53 were applied to both pre- and post-staging archival specimens from 60 individuals to identify four molecular subgroups: MMR-D, POLE EDM, p53 wild type, p53 abn (abnormal). Three gynecologic subspecialty pathologists assigned histotype and grade to a subset of samples. Concordance of molecular and clinicopathologic subgroup assignments were determined, comparing biopsy/curetting to hysterectomy specimens. Complete molecular and pathologic categorization was achieved in 57 cases. Concordance metrics for pre- vs. post-staging endometrial samples categorized by ProMisE were highly favorable; average per ProMisE class sensitivity(0.9), specificity(0.96), PPV(0.9), NPV(0.96) and kappa statistic 0.86(95%CI, 0.72-0.93), indicating excellent agreement. We observed the highest level of concordance for 'p53 abn' tumors, the group associated with the worst prognosis. In contrast, grade and histotype assignment from original pathology reports pre- vs. post-staging showed only moderate levels of agreement (kappa=0.55 and 0.44 respectively); even with subspecialty pathology review only moderate levels of agreement were observed. Molecular classification can be achieved on diagnostic endometrial samples and accurately

    The aim of this study was to evaluate the diagnostic ability of magnetic resonance imaging (MRI) in premenopausal women with G1 endometrial carcinoma. Twenty-six patients underwent T2W, diffusion weighted, and dynamic contrast-enhanced 3-T MRI. The degree of myometrial invasion was pathologically classified into no invasion, shallow (3 mm or less), and more. Two radiologists assessed myometrial invasion on MRI. Diagnostic accuracy, sensitivity, specificity, positive and negative predictive values, AUC, and interobserver agreement were analyzed. For assessing myometrial invasion, mean accuracy, sensitivity, specificity, positive predictive values, negative predictive values, and AUC, respectively, were as follows: 63%, 42%, 85%, 79%, 47%, and 0.75. Mean interobserver agreement was fair (k = 0.36). Shallow invasions were underestimated as no invasion on MRI in all 6 cases. Magnetic resonance imaging produced false-negative result on half of patients. The misjudgments tended to happen in patients with shallow invasion.

    Purpose: The current study was conducted to investigate the incidence and risk factors for medical complications associated with low dose rate brachytherapy in patients with medically inoperable Stage I endometrial cancer treated with irradiation alone. Methods and Materials: From 1965 through 1991 at Mallinckrodt Institute of Radiology, 150 implants were performed on 96 patients who were deemed medically unfit for hysterectomy because of advanced age, obesity, and various medical problems. The records of these patients were examined retrospectively to determine the incidence of medical complications that occurred in the first 30 days following the initiation of brachytherapy. The association of risk factors that precluded major surgery and the occurrence of brachytherapy-related complications was examined by logistic regression. Results: Of these 96 patients, 40 patients were older than 75 years, and 31 patients were deemed morbidly obese. Medical problems included hypertension in 45 patients, and diabetes in 37; there was a history of congestive heart failure in 23, stroke in 11, myocardial infarction in 10, and thromboembolism in 8. There were concurrent malignancies in five patients. Implants were performed using intrauterine Simon-Heyman capsules, tandems, and vaginal ovoids in all patients. General anesthesia was used for 98 implants, spinal anesthesia for 26, local anesthesia for 25, and epidural anesthesia for 1. The duration of anesthesia ranged from 30 to 120 min (median, 60 min). The duration of radioisotope application ranged from 11 to 96 h (median, 46 h). Preventive measures included low dose subcutaneous heparin in 55 patients (since 1978), and intermittent pneumatic compression boots in 29 (since 1985). Four patients developed life-threatening complications including myocardial infarction (two patients), congestive heart failure (one patient), and pulmonary embolism (one patient). Two of these four patients died; one with a myocardial infarction and

      "nAbnormal uterine bleeding, whether in peri menopausal or postmenopausal patients, is an important clinical concern and results in much medical intervention. When bleeding occurs in women over 40 years of age as well as any postmenopausal women, endometrial assessment is mandatory.

    Purpose: Cylindrical applicators are often used for postoperative HDRbrachytherapy in endometrial carcinoma. It has been considered that dosimetric variation between fractions for this treatment is minimal and might not be necessary to perform treatment planning for every fractions. At our institute, it is traditional to perform treatment planning with CT simulation on the first fraction and uses this plan for the rest of treatment. This study was aim to evaluate the errors of critical structure doses between the fractions when simulation and planning were done for first fraction only. Methods: Treatment plans of 10 endometrial carcinoma patients who received postoperative HDR-brachytherapy and underwent CT-simulation for every HDR-fractions at our department were retrospectively reviewed. All of these patients were treated with cylindrical applicator and prescribed dose 15Gy in 3 fractions to 0.5cm from vaginal surface. The treatment plan from the first fraction was used to simulate in second and third CT-simulation. Radiation dose for critical structures in term of Dose-to-2cc (D2cc) were evaluated and compared between planning CT. Results: The D2cc for bladder and rectum were evaluated. For bladder, the mean error of D2cc estimation for second and third fractions was 7.6% (0.1–20.1%, SD=5.7). And the mean error for D2cc of rectum was 8.5% (0.1–29.4%, SD=8.5). Conclusion: The critical structure doses could be significant difference between fractions which may affects treatment outcomes or toxicities. From our data, image-guided brachytherapy at least with CT-Simulation should be done for every treatment fractions.

    Hyaluronan accumulation correlates with the degree of malignancy in many solid tumor types, including malignant endometrial carcinomas. To elucidate the mechanism of hyaluronan accumulation, we examined the expression levels of the hyaluronan synthases (HAS1, HAS2 and HAS3) and hyaluronidases (HYAL1 and HYAL2), and correlated them with hyaluronan content and HAS1-3 immunoreactivity. A total of 35 endometrial tissue biopsies from 35 patients, including proliferative and secretory endometrium (n = 10), post-menopausal proliferative endometrium (n = 5), complex atypical hyperplasia (n = 4), grade 1 (n = 8) and grade 2 + 3 (n = 8) endometrioid adenocarcinomas were divided for gene expression by real-time RT-PCR, and paraffin embedded blocks for hyaluronan and HAS1-3 cytochemistry. The mRNA levels of HAS1-3 were not consistently changed, while the immunoreactivity of all HAS proteins was increased in the cancer epithelium. Interestingly, HAS3 mRNA, but not HAS3 immunoreactivity, was increased in post-menopausal endometrium compared to normal endometrium (p = 0.003). The median of HYAL1 mRNA was 10-fold and 15-fold lower in both grade 1 and grade 2+3 endometrioid endometrial cancers, as compared to normal endometrium (p = 0.004-0.006), and post-menopausal endometrium (p = 0.002), respectively. HYAL2 mRNA was also reduced in cancer (p = 0.02) and correlated with HYAL1 (r = 0.8, p = 0.0001). There was an inverse correlation between HYAL1 mRNA and the epithelial hyaluronan staining intensity (r = -0.6; P = 0.001). The results indicated that HYAL1 and HYAL2 were coexpressed and significantly downregulated in endometrioid endometrial cancer and correlated with the accumulation of hyaluronan. While immunoreactivity for HASs increased in the cancer cells, tumor mRNA levels for HASs were not changed, suggesting that reduced turnover of HAS protein may also have contributed to the accumulation of hyaluronan

    DNA repair and G2-phase cell cycle checkpoint responses are involved in the manifestation of hyper-radiosensitivity (HRS). The low-dose radioresponse of MSH2 isogenic endometrial carcinoma cell lines was examined. Defects in cell cycle checkpoint activation and the DNA damage response in irradiated cells (0.2 Gy) were evaluated. HRS was expressed solely in MSH2+ cells and was associated with efficient activation of the early G2-phase cell cycle checkpoint. Maintenance of the arrest was associated with persistent MRE11, γH2AX, RAD51 foci at 2 h after irradiation. Persistent MRE11 and RAD51 foci were also evident 24 h after 0.2 Gy. MSH2 significantly enhances cell radiosensitivity to low dose IR.

    In a prospective bacteriological and clinical study the vaginal bacterial flora of 35 patients with endometrial carcinoma, who underwent surgery 4 to 6 weeks earlier, was investigated prior to and following intracavitary vaginal irradiation with 10 Gy in 0,75 cm (Ir-192, afterloading device, Buchler). Bacteriological swabs were taken prior to and following the insertion of a tube applicator. Anaerobic transport-media were used and cultures were performed aerobically and anaerobically. The mean number of aerobic species per patient increased slightly from 3.26 to 3.60 (n.s.), anaerobic species remained constant (1.36 before and 1.30 after irradiation). Also the frequency of isolation of most aerobic and of all anaerobic species was statistically not altered following irradiation. Staphylococcus epidermidis decreased from 51.4% to 22.8% significantly (2p [de

    Background MicroRNAs (miRNAs, miRs) are small non-coding RNAs that negatively regulate gene expression at the post-transcriptional level. MicroRNAs are dysregulated in cancer and may play essential roles in tumorigenesis. Additionally, miRNAs have been shown to have prognostic and diagnostic value in certain types of cancer. The objective of this study was to identify dysregulated miRNAs in endometrioid endometrial adenocarcinoma (EEC) and the precursor lesion, complex atypical hyperplasia (CAH). Methodology We compared the expression profiles of 723 human miRNAs from 14 cases of EEC, 10 cases of CAH, and 10 normal proliferative endometria controls using Agilent Human miRNA arrays following RNA extraction from formalin-fixed paraffin-embedded (FFPE) tissues. The expression of 4 dysregulated miRNAs was validated using real time reverse transcription-PCR. Results Forty-three miRNAs were dysregulated in EEC and CAH compared to normal controls (p<0.05). The entire miR-200 family (miR-200a/b/c, miR-141, and miR-429) was up-regulated in cases of EEC. Conclusions This information contributes to the candidate miRNA expression profile that has been generated for EEC and shows that certain miRNAs are dysregulated in the precursor lesion, CAH. These miRNAs in particular may play important roles in tumorigenesis. Examination of miRNAs that are consistently dysregulated in various studies of EEC, like the miR-200 family, will aid in the understanding of the role that miRNAs play in tumorigenesis in this tumour type.

    Full Text Available Endometrial cancers exhibit a different mechanism of tumorigenesis and progression depending on histopathological and clinical types. The most frequently altered gene in estrogen-dependent endometrioid endometrial carcinoma tumors is PTEN. Microsatellite instability is another important genetic event in this type of tumor. In contrast, p53 mutations or Her2/neu overexpression are more frequent in non-endometrioid tumors. On the other hand, it is possible that the clear cell type may arise from a unique pathway which appears similar to the ovarian clear cell carcinoma. K-ras mutations are detected in approximately 15%–30% of endometrioid carcinomas, are unrelated to the existence of endometrial hyperplasia. A β-catenin mutation was detected in about 20% of endometrioid carcinomas, but is rare in serous carcinoma. Telomere shortening is another important type of genomic instability observed in endometrial cancer. Only non-endometrioid endometrial carcinoma tumors were significantly associated with critical telomere shortening in the adjacent morphologically normal epithelium. Lynch syndrome, which is an autosomal dominantly inherited disorder of cancer susceptibility and is characterized by a MSH2/MSH6 protein complex deficiency, is associated with the development of non-endometrioid carcinomas.

    From March of 1979 through December of 1982, 84 patients with supraglottic carcinoma were seen and evaluated in the Department of Therapeutic Radiology, Seoul National University Hospital. Of these, 68 patients were treated with a curative intent by employing either radiotherapy alone or a combined approach of radiotherapy plus surgery. Sixteen patients refused to complete the treatment program. Seventy-three per cent of patients had T3 and T4 lesions and 63% of patients had lymph node metastasis at the time of diagnosis. Actuarial recurrence-free survival at 3 year was: Stage I-III 62%, Stage III 54%, Stage IV 18%. For T1-2, T3 and T4 lesions, the actuarial recurrence free survival at 3 years were 50%, 34% and 9% respectively. Of 39 patients with treatment failure, 29 patients (78%) had uncontrol or ultimate recurrence at the primary site while 9 patients having lymph node recurrence, 14 patients(21%) had lymph node recurrence, and 5 patients had distant metastasis. It is suggested that planned combined radiotherapy is indicated for advanced but respectable supraglottic carcinoma

    Hypoxia inducible factor 1α (HIF-1α) plays an essential role in the adaptive response of cells to hypoxia and is associated with aggressive tumour behaviour. We have shown p27 kip1 , which is generally reduced in endometrial cancer, to be re-expressed in hypoxic regions. This possibly contributes to survival of cancer cells. The aim of this study was to evaluate the prognostic value of HIF-1α and p27 kip expression in patients with endometrioid endometrial cancer. Expression levels of HIF-1α, CAIX, Glut-1, and p27 kip1 were analyzed by immunohistochemistry. Percentage of positive cells, staining pattern (perinecrotic, diffuse, or mixed) and presence of necrosis were noted. Necrosis was correlated with shortened disease free survival (DFS) (p = 0.008) and overall survival (OS) (p = 0.045). For DFS, perinecrotic HIF-1α expression was also prognostic (p = 0.044). Moreover, high p27 kip1 expression was an additional prognostic factor for these patients with perinecrotic HIF-1α expression. In multivariate Cox regression, perinecrotic HIF-expression emerged as an independent prognostic factor. Perinecrotic HIF-1α expression was significantly associated with CAIX and Glut-1 expression, pointing towards functional HIF-1. In patients with endometrioid endometrial cancer, necrosis and necrosis-related expression of HIF-1α are important prognostic factors. More aggressive adjuvant treatment might be necessary to improve the outcome of patients with these characteristics

    Carcinoma of the endometrium is the most common invasive gynecologic malignancy of the female genital tract. Clinically, patients with endometrial carcinoma present with abnormal uterine bleeding. The role of magnetic resonance imaging (MRI) in endometrial carcinoma is disease staging and treatment planning. MRI has been shown to be the most valuable imaging mod-ality in this task, compared with endovaginal ultrasound and computed tomography, because of its intrinsic contrast resolution and multiplanar capability. MRI protocol includes axial T1-weighted images; axial, sagittal, and coronal T2-weighted images; and dynamic gadolinium-enhanced T1-weighted imaging. MR examination is usually performed in the supine position with a phased array multicoil using a four-coil configuration. Endometrial carcinoma is isointense with the normal endometrium and myometrium on noncontrast T1-weighted images and has a variable appearance on T2-weighted images demonstrating heterogeneous signal intensity. The appearance of noninvasive endometrial carcinoma on MRI is characterized by a normal or thickened endometrium, with an intact junctional zone and a sharp tumor-myometrium interface. Invasive endometrial carcinoma is characterized disruption or irregularity of the junctional zone by intermediate signal intensity mass on T2-weighted images. Invasion of the cervical stroma is diagnosed when the low signal intensity cervical stroma is disrupted by the higher signal intensity endometrial carcinoma. MRI in endometrial carcinoma performs better than other imaging modalities in disease staging and treatment planning. Further, the accuracy and the cost of MRI are equivalent to those of surgical staging.

Here we report a uterine neoplasm with a unique combination of endometrioid adenocarcinoma and mixed germ cell malignant elements. A 28-year-old woman with abnormal vaginal bleeding, an abdominal mass, and elevated alfa-fetoprotein and beta-human chorionic gonadotropin (ß-hCG levels had a history of biopsy of an omental mass and chemotherapy in another hospital one month before her referral to our department. Histologic examination of the mass removed from the omentum revealed an endometrioid adenocarcinoma with yolk sac tumor-like differentiation. Total abdominal hysterectomy, bilateral salpingo-oophorectomy, infracolic omentectomy, and removal of metastatic disease were then undertaken at our hospital. Postoperative chemotherapy was given. Eight months postoperatively, serum alfa-fetoprotein and ß-hCG rose again. Cases with primary yolk sac tumors of the endometrium or endometrial carcinoma with trophoblastic differentiation in the literature were reviewed.

    Objective: Dose prescription and definition of target volume in brachytherapy of cervical and endometrial cancer are calculated to standard points as Manchester point A or point My(ometrium) in most centers. Calculation of doses to organs at risk mainly relies on ICRU-report 38. But standard dose prescription neglects individual patient anatomy. While MRI and CT had widespread impact on individual planning in external beam radiotherapy, there is still a minor influence on brachytherapy. The impact of individual anatomy on dose distribution in target volume and organs at risk demonstrates the objective of individual brachytherapy planning. Materials and Methods: 8 patients with cervical and 4 patients with endometrial carcinoma underwent MRI of the pelvis with in-situ applicators (ring-tandem applicators for cervical carcinoma and modified Heyman-capsules for endometrial carcinoma). T1w slices were angulated coronal and sagittal to get rectangular reproductions to applicator axis. Orthogonal or isocentric X-ray films for conventional treatment planning were done. MRI-information on target and organs at risk was transformed into coordinates relative to applicator axis and dose calculation on the database of conventional treatment planning was performed by Nucletron Planning System PLATO. Isodoses were projected into MRI slices. Prescribed dose to patients with cervical cancer was 8.5 Gy to point A resp. 10 Gy to point My (2cm below fundal myometrium and 2cm lateral applicator axis) in endometrial cancer. Results: Dose prescription to Manchester point A or point My represented in only 50% of cases uterine serosa. Instead of 2cm lateral of applicator axis, uterine surface ranged from 1.0 cm to 3.9 cm at the level of point A (mean 2.25 cm coronal and 1.77 cm sagittal) and from 1.5 cm to 4.4 cm at the level of point My (mean 2.7 cm coronal and 2.1 cm sagittal). Uterine volume ranged from 69 cc to 277 cc, mean volume was 150cc. Dose-volume histograms of patients with

    The management of endometrial carcinoma is constantly evolving. The SFOG and the CNGOF decided to jointly update the previous French recommendations (Institut national du cancer 2011) and to adapt to the French practice the 2015 recommendations elaborated at the time of joint European consensus conference with the participation of the three concerned European societies (ESGO, ESTRO, ESMO). A strict methodology was used. A steering committee was put together. A systematic review of the literature since 2011 has been carried out. A first draft of the recommendations has been elaborated, with emphasis on high level of evidence. An external review by users representing all the concerned discipines and all kinds of practice was completed. Three hundred and four comments were sent by 54 reviewers. The management of endometrial carcinoma requires a precise preoperative workup. A provisional estimate of the final stage is provided. This estimation impact the level of surgical staging. Surgery should use a minimal invasive approach. The final pathology is the key of the decision concerning adjuvant therapy, which involves surveillance, radiation therapy, brachytherapy, or chemotherapy. The management algorithms allow a fast, state of the art based, answer to the clinical questions raised by the management of endometrial cancer. They must be used only in the setting of a multidisciplinary team at all stages of the management. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Do fertility drugs influence the subsequent risk of endometrial cancer in a manner that is independent of other risk predictors, such as parity? In this follow-up of a large cohort of women evaluated for infertility and for whom information was captured on fertility drugs, indications for usage and other risk factors that might influence cancer risk, we found no evidence for a substantial relationship between fertility drug use and endometrial cancer risk. Although the hormonal etiology of endometrial cancer has been well established, it remains unclear whether the use of fertility drugs has an influence on risk. Results regarding the effects of fertility drugs on endometrial cancer risk have been inconsistent, although several studies have shown some evidence for possible increases in risk. The relationship is of particular interest given that clomiphene, a commonly prescribed drug, is a selective estrogen receptor modulator, with chemical properties similar to tamoxifen, another drug linked to an increase in endometrial cancer risk. In a retrospective cohort of 12 193 women evaluated for infertility between 1965 and 1988 at five US sites, follow-up was pursued through 2010 via both passive as well as active (questionnaire) means. Among the 9832 subjects for whom follow-up was allowed and achieved, 259 346 at-risk person-years (i.e. prior to hysterectomy) were accrued, and 118 invasive endometrial cancers identified. Cox regression determined hazard ratios (HRs) and 95% confidence intervals (CIs) for fertility treatments adjusted for endometrial cancer risk factors and causes of infertility. Although we observed slight increases in endometrial cancer risk associated with clomiphene (HR = 1.39, 95% CI: 0.96-2.01) and the less commonly prescribed gonadotrophins (1.34, 0.76-2.37), there were no convincing relationships of risk with either cycles of use or cumulative exposures for either drug.

    We evaluated the clinical feasibility of a new injection technique for sentinel detection in endometrial carcinoma (EC), transcervical subepithelial injection into the isthmocervical region of the myometrium. We compared detection of sentinel lymph nodes (SLN) by single photon emission computed tomography with CT (SPECT/CT) with planar lymphoscintigraphy. This is a unicentric prospective study. In all patients, transcervical injection of 10 MBq Technetium-99m-nanocolloid was performed into the isthmocervical myometrium without anaesthesia. After 40 (30-60) min, lymphoscintigraphy and SPECT/CT were performed. Patent blue was administered before surgery. The number and localisation of SLN detected in SPECT/CT and lymphoscintigraphy were recorded and compared to the SLN and non-SLN dissected intra-operatively. Between August 2008 and March 2012, 31 patients with EC were enrolled. The new transcervical injection of labelling substances led to high intra-operative (90.3%) detection rates, pelvic bilateral (57%), para-aortic (25%). SPECT/CT significantly identified more SLN than lymphoscintigraphy (mean 2.2 (1-8) to 1.3 (1-7)) in more patients (29/31 (93.5%) to 21/31 (68%), pnegative predictive value (NPV) 100%, and false negative results 0%. Transcervical SLN marking in combination with SPECT/CT is easily applicable and leads to high physiologic detection rates in pelvic and para-aortic lymphatic drainage areas. Non-affected SLN truly predicted a non-affected LN basin. Combining both methods SLN dissection may be a safe and feasible staging technique for clinical routine in EC. Copyright © 2014 Elsevier Inc.

    Full Text Available SWI/SNF chromatin-modification complexes use the energy of ATP hydrolysis to remodel nucleosomes and to affect transcription and several cellular processes. Accordingly, their loss of function has been associated with malignant transformation. ARID1A (the expression of whose product, BAF250a, a key complex component, is lost when mutated has recently been identified as a tumor suppressor gene that is mutated in 46-57% of ovarian clear cell carcinoma (CCC. The purposes of this study are to assess the frequency of loss of BAF250a expression in endometrial CCC and whether this loss has any discernable clinicopathologic implications. 34 endometrial carcinomas with a CCC component (including 22 pure CCC, 8 mixed carcinomas with a 10% CCC component, and 4 carcinosarcomas with a CCC epithelial component, were evaluated by immunohistochemistry using a monoclonal antibody directed against the human BAF250a protein. 5 (22.7% of the 22 pure CCC were entirely BAF250a negative, whereas the remainder showed diffuse immunoreactivity. None of 4 carcinosarcomas and only 1 (12.5% of the 8 mixed carcinomas were BAF250a negative. There was no discernable relationship between BAF250a immunoreactivity status and tumor architectural patterns (solid, papillary or tubulocystic areas or cell type (flat, hobnail or polygonal. Of the 22 patients with pure CCC, 14, 2, 3, and 3 were International Federation of Gynecology and Obstetrics stages 1, II, III and IV respectively. Interestingly, all 5 BAF250a negative cases were late stage [stages III or IV] as compared with 1 of 17 BAF250a positive cases (p=0.0002. Thus, 83% (5/6 of all late stage cases were BAF250a [-], as compared with 0 (0% of the 16 early stage (I or II cases (p=.0002. BAF250a negative and positive cases did not show any statistically significant difference regarding patient age and frequency of lymphovascular invasion or myometrial invasion. As may be anticipated from the concentration of late stage cases in

    The observation of peritumoral granulomatous reactions (PGRs) in two endometrial carcinomas (ECs) with a PMS2-deficient/MLH1-intact expression pattern led us to investigate whether PGRs in EC were specifically associated with DNA mismatch repair (MMR) protein deficiency, particularly PMS2 loss. Hysterectomy specimens from 22 MMR protein-intact and 54 MMR protein-deficient ECs were reviewed with specific attention to the presence of a PGR and a tumour-associated lymphoid reaction [including tumour-infiltrating lymphocytes (TILs) and stromal lymphoid infiltrates]. The MMR protein-deficient ECs included 22 cases with combined MLH1/PMS2 loss, 11 with combined MSH2/MSH6 loss, 11 with isolated MSH6 loss, and 10 with PMS2 loss but intact MLH1 staining (including the two 'index' cases). Overall, PGRs were identified in seven of 54 (13%) MMR protein-deficient ECs, five of which showed a PMS2-deficient/MLH1-intact immunophenotype; three of these patients had germline PMS2 mutations and one additional patient had a germline MSH6 mutation. None of the MMR protein-intact tumours showed a PGR. Although five of the seven PGR-positive ECs had a high-grade histological component, six were stage I. Most ECs with PGRs also showed TILs and stromal lymphoid reactions, similarly to MMR protein-deficient ECs in general. MMR protein-deficient ECs, particularly those with PMS2 loss, occasionally show PGRs in addition to stromal lymphoid infiltrates and TILs. Therefore, PGRs could be considered to constitute a histological prompt for consideration of Lynch syndrome. The potential prognostic significance of PGRs in EC requires further study. © 2018 John Wiley & Sons Ltd.

    L1CAM was originally identified as an adhesion molecule involved in neural development. In many human carcinomas L1CAM is over-expressed and is associated with a bad prognosis. We previously reported that L1CAM was absent in the vast majority of endometrioid endometrial carcinomas (ECs) (type 1) but was strongly expressed in the more aggressive serous and clear-cell ECs (termed type 2). The differential regulation of L1CAM in ECs is not well understood. Recent evidence suggests that it can be regulated by epigenetic mechanisms. Here we investigated the role of DNA-methylation of the L1CAM promoter for expression. We also studied the relationship to cancer testis (CT-X) antigens that co-localize with L1CAM on chromosome Xq28, a region that is often activated in human tumors. We used EC cell lines and primary tumor tissues for our analysis. For expression analysis we employed RT-PCR and Western blotting. DNA-Methylation of the L1CAM promoter was determined after bisulfite conversation and DNA sequencing. Tumor tissues were examined by immunohistochemical (IHC) staining. We demonstrate that the treatment of L1CAM low/negative expressing EC cell lines with 5 ′ -Azacytidine (5-AzaC) or knock-down of DNMT1 (DNA methyltransferase 1) as well as the HDAC (histone deacetylase) inhibitor Trichostatin A (TSA) up-regulated L1CAM at the mRNA and protein level. The L1CAM gene has two promoter regions with two distinct CpG islands. We observed that the expression of L1CAM correlated with hypermethylation in promoter 1 and 5-AzaC treatment affected the DNA-methylation pattern in this region. The CT-X antigens NY-ESO-1, MAGE-A3 and MAGE-A4 were also strongly up-regulated by 5-AzaC or knock-down of DNMT1 but did not respond to treatment with TSA. Primary EC tumor tissues showed a variable methylation pattern of the L1CAM promoter. No striking differences in promoter methylation were observed between tumor areas with L1CAM expression and those without expression. L1CAM expression

    Endometrial hyperplasia is a precancerous lesion of the endometrium, commonly presenting with uterine bleeding. If managed expectantly, it frequently progresses to endometrial carcinoma, rates of which are increasing dramatically worldwide. However, the established treatment for endometrial hyperplasia (progestogens) involves multiple side effects and leaves the risk of recurrence. Metformin is the most commonly used oral hypoglycaemic agent in type 2 diabetes mellitus. It has also been linked to the reversal of endometrial hyperplasia and may therefore contribute to decreasing the prevalence of endometrial carcinoma without the fertility and side effect consequences of current therapies. However, the efficacy and safety of metformin being used for this therapeutic target is unclear and, therefore, this systematic review will aim to determine this. We will search the following trials and databases with no language restrictions: Cochrane Gynaecology and Fertility Specialised Register; Cochrane Central Register of Controlled Trials (CENTRAL); MEDLINE; EMBASE; EBSCO Cumulative Index to Nursing and Allied Health Literature; PubMed; Google Scholar; ClinicalTrials.gov; the WHO International Trials Registry Platform portal; OpenGrey and the Latin American and Caribbean Health Sciences Literature (LILACS). We will include randomised controlled trials (RCTs) of use of metformin compared with a placebo or no treatment, conventional medical treatment (eg, progestogens) or any other active intervention. Two review authors will independently assess the trial eligibility, risk of bias and extract appropriate data points. Trial authors will be contacted for additional data. The primary review outcome is the regression of endometrial hyperplasia histology towards normal histology. Secondary outcomes include hysterectomy rate; abnormal uterine bleeding; quality of life scores and adverse reactions to treatments. Dissemination of the completed review will be through the Cochrane

    Epithelial-stroma interactions in the endometrium are known to be responsible for physiological functions and emergence of several pathologic lesions. Periglandular stromal cells act on endometrial cells in a paracrine manner through sex hormones. In this study, we immunohistochemically evaluated the expression of epithelial-mesenchymal transition regulators (SNAIL/SLUG, TWIST, ZEB1), adhesion molecules (β-catenin and E-cadhenin), estrogen (ER)-progesterone (PR) receptor and their correlation with each other in 30 benign, 148 hyperplastic (EH), and 101 endometrioid-type endometrial carcinoma (EC) endometria. In the epithelial component, loss of expression in E-cadherin, ER and PR, and overexpression of TWIST and ZEB1 were significantly higher in EC than in EH (P<0.01). In the periglandular stromal component, β-catenin and SNAIL/SLUG expression were significantly higher in normal endometrium and simple without atypical EH compared with complex atypical EH and EC (P<0.01). In addition, periglandular stromal TWIST expression was significantly higher in EH group compared with EC (P<0.05). There was significantly negative correlation between β-catenin and ER, TWIST and ER, and TWIST and PR in hyperplastic and carcinomatous glandular epithelium, whereas there was a significantly positive correlation between β-catenin and SNAIL-SLUG, β-catenin and TWIST, β-catenin and ER, β-catenin and PR, SNAIL-SLUG and ER, SNAIL-SLUG and PR, TWIST and ER, TWIST and PR, in periglandular/cancer-associated stromal cells (P<0.01). In conclusion, the pattern of positive and negative correlations in the expression of epithelial-mesenchymal transition regulators (SNAIL-SLUG and TWIST), sex hormone receptors (ER and PR), and β-catenin between ECs and hyperplasia, as well as between epithelium and stroma herein, is suggestive of a significant role for these proteins and their underlying molecular processes in the development of endometrial carcinomas.

    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.

    This study reports on 5 years experience of the treatment of carcinoma of the cervix and poor-risk carcinoma of the body of the uterus using a combination of external beam radiotherapy and high-dose-rate intracavitary 60Co-brachytherapy using the Cathetron since 1979 at the Middlesex Hospital, London. Despite a reduction in external beam dose of 20% since 1979, survival rates for both diseases remain unchanged and also compare favourably with those of other centres; they are 70.02% for carcinoma of the cervix of all stages except Ia, and 81.17% for 'poor-risk' carcinoma of body of uterus of all stages. The complication rates were acceptable. Analysis of the results of treatment by stage of disease in those patients with carcinoma of the cervix revealed that, except for Stage I cases, the results were comparable with those reported in the literature. The reason for the poor results in Stage I was found to be due to the high proportion of patients of 35 years of age and under with Stage I disease who fared significantly worse than older patients.

    Purpose: The aim of this study was to evaluate dose distribution within uterus (clinical target volume [CTV]) and tumor (gross tumor volume [GTV]) and the resulting clinical outcome based on systematic three-dimensional treatment planning with dose-volume adaptation. Dose-volume assessment and adaptation in organs at risk and its impact on side effects were investigated in parallel. Methods and Materials: Sixteen patients with either locally confined endometrial carcinoma (n = 15) or adenocarcinoma of uterus and ovaries after bilateral salpingo-oophorectomy (n = 1) were included. Heyman packing was performed with mean 11 Norman-Simon applicators (3-18). Three-dimensional treatment planning based on computed tomography (n = 29) or magnetic resonance imaging (n = 18) was done in all patients with contouring of CTV, GTV, and organs at risk. Dose-volume adaptation was achieved by dwell location and time variation (intensity modulation). Twelve patients treated with curative intent received five to seven fractions of high-dose-rate brachytherapy (7 Gy per fraction) corresponding to a total dose of 60 Gy (2 Gy per fraction and α/β of 10 Gy) to the CTV. Four patients had additional external beam radiotherapy (range, 10-40 Gy). One patient had salvage brachytherapy and 3 patients were treated with palliative intent. A dose-volume histogram analysis was performed in all patients. On average, 68% of the CTV and 92% of the GTV were encompassed by the 60 Gy reference volume. Median minimum dose to 90% of CTV and GTV (D90) was 35.3 Gy and 74 Gy, respectively. Results: All patients treated with curative intent had complete remission (12/12). After a median follow-up of 47 months, 5 patients are alive without tumor. Seven patients died without tumor from intercurrent disease after median 22 months. The patient with salvage treatment had a second local recurrence after 27 months and died of endometrial carcinoma after 57 months. In patients treated with palliative intent

    Purpose: To evaluate the long-term results of treatment using adjuvant whole abdominal irradiation (WAPI) with a pelvic/vaginal boost in patients with Stage I-III endometrial carcinoma at high risk of intra-abdominopelvic recurrence, including clear cell (CC) and serous-papillary (SP) histologic features. Methods and Materials: In a prospective nonrandomized trial, 119 patients were treated with adjuvant WAPI between November 1981 and April 2000. All patients were analyzed, including those who did not complete therapy. The mean age at diagnosis was 66 years (range 39-88). Thirty-eight patients (32%) had 1989 FIGO Stage I-II disease and 81 (68%) had Stage III. The pathologic features included the following: 64 (54%) with deep myometrial invasion, 48 (40%) with positive peritoneal cytologic findings, 69 (58%) with high-grade lesions, 21 (18%) with positive pelvic/para-aortic lymph nodes, and 44 (37%) with SP or CC histologic findings. Results: The mean follow-up was 5.8 years (range 0.2-14.7). For the entire group, the 5- and 10-year cause-specific survival (CSS) rate was 75% and 69% and the disease-free survival (DFS) rate was 58% and 48%, respectively. When stratified by histologic features, the 5- and 10-year CSS rate for adenocarcinoma was 76% and 71%, and for serous papillary/CC subtypes, it was 74% and 63%, respectively (p=0.917). The 5- and 10-year DFS rate for adenocarcinoma was 60% and 50% and was 54% and 37% serous papillary/CC subtypes, respectively (p=0.498). For surgical Stage I-II, the 5-year CSS rate was 82% for adenocarcinoma and 87% for SP/CC features (p=0.480). For Stage III, it was 75% and 57%, respectively (p=0.129). Thirty-seven patients had a relapse, with the first site of failure the abdomen/pelvis in 14 (38%), lung in 8 (22%), extraabdominal lymph nodes in 7 (19%), vagina in 6 (16%), and other in 2 (5%). When stratified by histologic variant, 32% of patients with adenocarcinoma and 30% with the SP/CC subtype developed recurrent disease. Most

    To assess clinicopathologic outcomes between two nodal assessment approaches in patients with endometrioid endometrial carcinoma and limited myoinvasion. Patients with endometrial cancer at two institutions were reviewed. At one institution, a complete pelvic and para-aortic lymphadenectomy to the renal veins was performed in select cases deemed at risk for nodal metastasis due to grade 3 cancer and/or primary tumor diameter>2cm (LND cohort). This is a historic approach at this institution. At the other institution, a sentinel lymph node mapping algorithm was used per institutional protocol (SLN cohort). Low risk was defined as endometrioid adenocarcinoma with myometrial invasion <50%. Macrometastasis, micrometastasis, and isolated tumor cells were all considered node-positive. Of 1135 cases identified, 642 (57%) were managed with an SLN approach and 493 (43%) with an LND approach. Pelvic nodes (PLNs) were removed in 93% and 58% of patients, respectively (P<0.001); para-aortic nodes (PANs) were removed in 14.5% and 50% of patients, respectively (P<0.001). Median number of PLNs removed was 6 and 34, respectively; median number of PANs removed was 5 and 16, respectively (both P<0.001). Metastasis to PLNs was detected in 5.1% and 2.6% of patients, respectively (P=0.03), and to PANs in 0.8% and 1.0%, respectively (P=0.75). The 3-year disease-free survival rates were 94.9% (95% CI, 92.4-97.5) and 96.8% (95% CI, 95.2-98.5), respectively. Our findings support the use of either strategy for endometrial cancer staging, with no apparent detriment in adhering to the SLN algorithm. The clinical significance of disease detected on ultrastaging and the role of adjuvant therapy is yet to be determined. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available Background: Hypoxia-inducible factor 1α (HIF-1α plays an essential role in the adaptive response of cells to hypoxia, triggering biologic events associated with aggressive tumor behavior. Methods: Expression of HIF-1α and proteins in the HIF-1α pathway (Glut-1, CAIX, VEGF in paraffin-embedded specimens of normal (n = 17, premalignant (n = 17 and endometrioid endometrial carcinoma (n = 39 was explored by immunohistochemistry, in relation to microvessel density (MVD. Results: HIF-1α overexpression was absent in inactive endometrium but present in hyperplasia (61% and carcinoma (87%, with increasing expression in a perinecrotic fashion pointing to underlying hypoxia. No membranous expression of Glut-1 and CAIX was noticed in inactive endometrium, in contrast with expression in hyperplasia (Glut-1 0%, CAIX 61%, only focal and diffuse and carcinoma (Glut-1 94.6%, CAIX 92%, both mostly perinecrotically. Diffuse HIF-1α was accompanied by activation of downstream targets. VEGF was significantly higher expressed in hyperplasias and carcinomas compared to inactive endometrium. MVD was higher in hyperplasias and carcinomas than in normal endometrium (p < 0.001. Conclusion: HIF-1α and its downstream genes are increasingly expressed from normal through premalignant to endometrioid adenocarcinoma of the endometrium, paralleled by activation of its downstream genes and increased angiogenesis. This underlines the potential importance of hypoxia and its key regulator HIF-1α in endometrial carcinogenesis.

    Full Text Available BACKGROUND Hysteroscopic-guided biopsy is the gold standard for endometrial sampling, but it carries risk of general anaesthesia, infection and perforation, whereas Pipelle does not require anaesthesia or cervical dilatation and it allows outpatient and painless endometrial sampling. The aim of the study is to determine the reliability and accuracy of Pipelle aspiration in acquiring an adequate and representative endometrial sample and to compare its histopathology with hysteroscopic-directed biopsy. MATERIALS AND METHODS A prospective observational comparative study evaluating the role of Pipelle aspiration as an outpatient procedure in endometrial sampling of perimenopausal women with AUB. 150 perimenopausal women with clinical diagnosis of abnormal uterine bleeding were selected from the Gynaecology OPD of IOG, Chennai, between October 2014 and September 2015. They were subjected to endometrial sampling by Pipelle followed by hysteroscopic-directed biopsy. The efficacy of Pipelle was determined by correlating the histopathological results obtained from it and the hysteroscopic-directed biopsy. RESULTS The histopathology of the endometrium obtained using Pipelle’s curette showed a sensitivity of 93%, specificity of 90% in the detection of abnormal findings with PPV of 88% and NPV of 94%. However, accuracy of Pipelle is found to be less in the diagnosis of polyps and submucous fibroids with accuracy of nearing 100% when using hysteroscopy. CONCLUSION Pipelle endometrial sampling is convenient, easy, painless and safe in obtaining an adequate sample for histopathology with high sensitivity and specificity for endometrial pathologies and endometrial carcinoma.

    Lysophosphatidic acid (LPA) has potent growth-regulatory effect in many cell types and has been linked to the in vivo tumor growth and metastasis in several malignancies. The goal of this study was to assess the regulation of (EC) microenvironment by LPA through the examination of its effect on cell proliferation, migration, invasion, uPA activity, and matrix metalloproteinase (MMP) secretion/activation. All experiments were performed in vitro using an EC cell line, HEC-1A. Cell proliferation was determined using the Promega MTS proliferation assay following 48 h of exposures to different concentrations of LPA (0.1, 1.0 and 10.0 microM). Cell invasion was assessed using a modified Boyden chamber assay with collagen I coated on the membrane. HEC-1A motility was examined by Boyden chamber migration assay as well as the scratch wound closure assay on type I collagen. MMP secretion/activation in HEC-1A conditioned medium was detected by gelatin zymography. MMP-7 mRNA expression was determined using real-time PCR. uPA activity was measured using a coupled colorimetric assay. LPA, at the concentrations of 0.1 and 1.0 microM, significantly induced the proliferation of HEC-1A cells (p0.05). Gelatin zymogram showed that HEC-1A cells secreted high levels of MMP-7, while MMP-2 and MMP-9 are barely detectable. In addition, LPA significantly enhanced uPA activity in HEC-1A conditioned medium in a concentration-dependent manner. LPA is a potent modulator of cellular proliferation and invasion for EC cells. It also has the capacity to stimulate the secretion/activity of uPA and MMP-7. Those results suggest that LPA is a bioactive modulator of EC microenvironment and may have a distinct regulation mechanism as observed in epithelial ovarian cancer. Copyright 2009.

    Objective: The aim of this study was to develop a new reporting format for endometrial cytology that would standardize the diagnostic criteria and the terminology used for reporting. Methods: In previous studies, cytoarchitectural criteria were found to be useful for the cytological assessment of endometrial lesions. To apply these criteria, an appropriate cytological specimen is imperative. In this article, the requirements of an adequate endometrial cytological specimen for the new diagnostic criteria are first discussed. Then, the diagnostic criteria, standardized on a combination of conventional and cytoarchitectural criteria, are presented. Third, terminology that could be used, not only for reporting the histopathological diagnosis, but also for providing better guidance for the gynaecologist to determine further clinical action, is introduced. The proposed reporting format was investigated using endometrial cytology of 58 cases that were cytologically underestimated or overestimated compared to the histopathological diagnosis made on the subsequent endometrial biopsy or surgical specimens. Results: Of the 58 cases, 12 were reassessed as being unsatisfactory for evaluation. Among the remaining 46 cases, 25 of the 27 cases, which had been underestimated and subsequently diagnosed as having endometrial carcinoma or a precursor stage on histopathological examination,were reassessed as recommended for endometrial biopsy. On the other hand, 19 cases overestimated by cytology were all reassessed as not requiring biopsy. Conclusions: The reporting format for endometrial cytology proposed in this article may improve diagnostic accuracy and reduce the number of patients managed inappropriately. PMID:18657157

    Stage IIIC endometrial carcinoma (EC) represents pathologically heterogenous patients with single/multiple pelvic (stage IIIC1) or paraaortic (stage IIIC2) lymph nodes (LNs). There is an increasing trend to offer adjuvant chemotherapy (CT) +/- radiation (RT) uniformly to these patients, regardless of substage. We investigate the prognostic significance of positive LN (pLN) number, ratio (%pLN), location (IIC1 vs. IIC2), and adjuvant treatment on patterns of failure and survival in a large collaborative multi-institutional series. Clinical data for stage III EC patients such as patient characteristics, surgery/pathologic details, adjuvant therapies (including CT, RT, and chemotherapy and radiation), and outcomes (including pelvic control [PC], disease-free survival [DFS], distant DFS, and overall survival [OS]) were collected from 3 academic institutions. Log-rank analyses, Cox regression univariate and multivariate analyses were performed. Of the 264 patients queried for stage III disease, 237 (73%) had pLN, and complete LN sampling for analysis. The mean number of pLN in the combined data were 3.9, with 26.1% of all LN sampled positive; 121 patients (51%) staged IIIC1, and 116 patients (49%) staged IIIC2. There was a significant difference in number of pLN (P=0.0006) and total LN sampled by institution (range, 13 to 35; P=0.0004), without a difference in %pLN (P=0.35). Ninety-seven of 220 (44.1%) have ≥20% pLN. While controlling for substage and institution, a decrease in DFS (hazard ratio [HR], 1.1; P=0.007), and OS (HR, 1.1; P=0.01) was observed with every increase of 10% in the pLN ratio. There was a significant difference in DFS (HR, 1.8; P=0.003), PC (HR, 1.9; P=0.004), and distant DFS (HR, 1.6; P=0.03), as well as a trend for decreased OS (HR, 1.6; P=0.08) for substage IIIC2 versus IIIC1 disease; 5 years DFS 40% versus 45%, OS 50% versus 57%. Patients received no adjuvant therapy (10%), CT alone (27%), RT alone (16%), or chemotherapy and radiation (47

    Given that endometrial cancer (EC) is often the sentinel cancer for female Lynch syndrome patients, we have successfully implemented universal screening of ECs and have previously shown that this is the preferred method to identify these patients. However, during the course of universal screening of EC, we encountered 6 cases with an unusual pattern of mismatch-repair protein immunohistochemistry that has not been previously described in this setting. In these 6 cases, there was an abrupt loss of MLH1 and PMS2 expression in a portion of the tumor. In 3 cases, marked histologic differences were identified between the areas of the tumor with retained expression and areas with loss of expression. In 2 cases, the areas with loss of expression were of higher grade (1 demonstrated solid growth and the other demonstrated increased nuclear atypia with diffuse p53 expression). In 4 tumors, histologic features associated with microsatellite instability (MSI) were present, including increased intraepithelial lymphocytes. The areas with loss of and retained MLH1/PMS2 expression were separately microdissected and assessed for MSI and MLH1 promoter methylation. The areas with loss of MLH1 and PMS2 more commonly demonstrated MSI compared with the areas with intact expression (83% vs. 33%). MLH1 promoter methylation analysis demonstrated heterogenous hypermethylation, as all areas with loss of MLH1/PMS2 expression had more extensive methylation of MLH1 compared with those areas with retained expression. In summary, we describe the histologic and molecular features of 6 cases of EC with abrupt loss of MLH1 and PMS2 expression and demonstrate that heterogenous methylation of the MLH1 promoter results in this distinct and unusual pattern of immunohistochemical expression.

    To provide an update for nurses involved in the care of women at risk or being treated for endometrial cancer. Review articles, research reports, and medical and nursing text-books. Endometrial cancer is the most common gynecologic malignancy. Although most women with endometrial cancer present with early stage disease and have an excellent chance of cure, approximately 6,600 women in the United States are expected to die from the disease in 2002. Treatment of patients with advanced or recurrent disease remains challenging, with no proven best standard of treatment. Nursing plays an important role in prevention and early detection of endometrial cancer, patient education, patient care, and rehabilitation.

    A total of 47 patients with a diagnosis of nasopharyngeal carcinoma was treated in Department of Therapeutic Radiology, Seoul National University Hospital during last 4 years. Of the 47 patients, 23(49%) had undifferentiated carcinoma, 20(43%) had squamous cell carcinoma, while 4(8%) had lymphoepithelioma. Most of the patients(71%) has Stage IV disease, cervical lymph node metastases were found in 36(77%) and distant metastasis was found in 1 at the time of diagnosis. Complete response rate after radiotherapy for 47 patients of nasopharyngeal carcinoma was 85.1%. The overall actuarial 3 year survival rates was 0.718 and the disease free actuarial 3 year survival rates was 0.468. Nodal involvement and symptom duration were statistically significant influencing factors for actuarial survival rate. Treatment failures were found in 20 patients (42.6%), local recurrence only in 6(30%), local and neck recurrence in 3(15%), local recurrence with metastasis in 4(20%) and distant metastasis only in 7(35%). Local failures were more frequent in the patients with cranial nerve symptoms (P=0.032). Distant metastases were more frequent with T4 lesions (P=0.047), and with nodal involvement (P<0.01). Retreatment after the tumor recurrence was chemotherapy and/or radiotherapy, two patients retreated for local recurrence were alive without evidence of disease for more than 19 and 44 months after retreatment

    Purpose/objective: Whole “conventional” pelvic irradiation (up to 45–50 Gy) following hysterectomy is associated with a high rate of adverse gastro-intestinal (GI) adverse events, of which around 60% correspond to acute grade 2 toxicity. The phase II RTCMIENDOMETRE trial was designed to test the hypothesis that IMRT could reduce the incidence of grade 2 or more acute GI toxicity to less than 30% in patients irradiated post-operatively for an endometrial cancer. Materials/methods: Patients with post-operative stage Ib G3, Ic or II endometrial carcinomas with no history of chronic inflammatory bowel disease were eligible. Guidelines for volume delineation and dose prescription were detailed in the protocol. The investigators were advised to use a web-based atlas developed for the RTOG 0418 study. The dose of the vaginal and nodal PTV was 45 Gy in 25 fractions. To assess the ability of the participating centres to comply with the protocol guidelines, they were requested to complete a dummy run procedure before inclusion of their 1st patient. GI and genito-urinary (GU) toxicity were graded according to the CTCAE V 3.0 classification and were prospectively recorded every week during irradiation, as well as at time of brachytherapy insertions and during the follow-up visit at week 15 (W15). Special attention was given to note any changes to the grade of adverse events between W5 and W15. Results: From May 2008 to April 2010, 49 patients from 6 centres were recruited for the trial. One patient could not be treated, one patient died of vascular stroke at W3 without toxicity, and 1 patient refused to be followed-up after treatment. Thus, 46 cases were available for analysis at W15. The distribution by stage was as follows: Ib 16.3%, Ic 64.2%, II 20.4%. Thirty six patients (75%) received an additional vaginal vault boost of 6–10 Gy delivered by HDR brachytherapy in 1 or 2 fractions. Among the 47 patients who completed IMRT, 27% (95% CI 14.5–39.7%) developed at

    To determine if a sentinel lymph node (SLN) mapping algorithm will detect metastatic nodal disease in patients with intermediate-/high-risk endometrial carcinoma. Patients were identified and surgically staged at two collaborating institutions. The historical cohort (2004-2008) at one institution included patients undergoing complete pelvic and paraaortic lymphadenectomy to the renal veins (LND cohort). At the second institution an SLN mapping algorithm, including pathologic ultra-staging, was performed (2006-2013) (SLN cohort). Intermediate-risk was defined as endometrioid histology (any grade), ≥50% myometrial invasion; high-risk as serous or clear cell histology (any myometrial invasion). Patients with gross peritoneal disease were excluded. Isolated tumor cells, micro-metastases, and macro-metastases were considered node-positive. We identified 210 patients in the LND cohort, 202 in the SLN cohort. Nodal assessment was performed for most patients. In the intermediate-risk group, stage IIIC disease was diagnosed in 30/107 (28.0%) (LND), 29/82 (35.4%) (SLN) (P=0.28). In the high-risk group, stage IIIC disease was diagnosed in 20/103 (19.4%) (LND), 26 (21.7%) (SLN) (P=0.68). Paraaortic lymph node (LN) assessment was performed significantly more often in intermediate-/high-risk groups in the LND cohort (P<0.001). In the intermediate-risk group, paraaortic LN metastases were detected in 20/96 (20.8%) (LND) vs. 3/28 (10.7%) (SLN) (P=0.23). In the high-risk group, paraaortic LN metastases were detected in 13/82 (15.9%) (LND) and 10/56 (17.9%) (SLN) (%, P=0.76). SLN mapping algorithm provides similar detection rates of stage IIIC endometrial cancer. The SLN algorithm does not compromise overall detection compared to standard LND.

    Based on The Cancer Genome Atlas, we previously developed and confirmed a pragmatic molecular classifier for endometrial cancers; ProMisE (Proactive Molecular Risk Classifier for Endometrial Cancer). ProMisE identifies four prognostically distinct molecular subtypes, and can be applied to diagnostic specimens (biopsy/curettings), enabling earlier informed decision-making. We have strictly adhered to the Institute of Medicine (IOM) guidelines for the development of genomic biomarkers, and herein present the final validation step of a locked-down classifier prior to clinical application. We assessed a retrospective cohort of women from the Tübingen University Women's Hospital treated for endometrial carcinoma between 2003-13. Primary outcomes of overall, disease-specific and progression-free survival were evaluated for clinical, pathological, and molecular features. Complete clinical and molecular data were evaluable from 452 women. Patient age ranged from 29 - 93 (median 65) years, and 87.8% cases were endometrioid histotype. Grade distribution included 282 (62.4%) G1, 75 (16.6%) G2, and 95 (21.0%) G3 tumors. 276 (61.1%) patients had stage IA disease, with the remaining stage IB (89 (19.7%)), stage II (26 (5.8%)), and stage III/IV (61 (13.5%)). ProMisE molecular classification yielded 127 (28.1%) MMR-D, 42 (9.3%) POLE, 55 (12.2%) p53abn, and 228 (50.4%) p53wt. ProMisE was a prognostic marker for progression-free (P=0.001) and disease-specific (P=0.03) survival even after adjusting for known risk factors. Concordance between diagnostic and surgical specimens was highly favorable; accuracy 0.91, kappa 0.88. We have developed, confirmed and now validated a pragmatic molecular classification tool (ProMisE) that provides consistent categorization of tumors and identifies four distinct prognostic molecular subtypes. ProMisE can be applied to diagnostic samples and thus could be used to inform surgical procedure(s) and/or need for adjuvant therapy. Based on the IOM

    To report on the unique, innovative management of a super morbidly obese patient presenting for fertility preservation in the setting of Grade 2 endometrioid endometrial adenocarcinoma. A back-to-back oocyte retrieval and robot-assisted total laparoscopic hysterectomy (RA-TLH) with bilateral salpingo-oophorectomy (BSO) was performed in a 37-year-old nulligravid woman with super morbid obesity (BMI 63 kg/m 2 ) with endometrial cancer. the successful retrieval of oocytes for fertility preservation and oncologic intervention via RA-TLH with BSO in the same operative and anesthetic episode. This combined procedure strategy was successful in our case and is a feasible option for similar high-risk patients in the future. Identifying safe and effective approaches for oocyte retrieval in morbidly obese patients represents a pressing need as obesity rates rise among reproductive-aged women. Back-to-back oocyte retrieval and RA-TLH with BSO are not only feasible, but could also decrease significant anesthetic risks for morbidly obese patients.

    Full Text Available Background/Aim. The prevalence of endometrial polyps (EPs in the general female population is about 24%. Abnormal uterine bleeding is frequently the presenting symptom of EPs. The aim of this study was to determine the prevalence and characteristics of EPs in patients with abnormal uterine bleeding. Methods. The prevalence and characteristics of EPs were investigated in 961 patients with abnormal uterine bleeding who underwent dilatation and curettage between January and December 2006. Regarding histopathological features of EPs (presence of atypical hyperplasia or endometrial carcinoma, patients were divided into two groups: group A - patients who had EPs and EPs with hyperplasia without atypia (n = 204 and group B - patients who had EPs with atypical hyperplasia and EPs with carcinoma (n = 7. Results. In 211 (21.94% patients EPs were found with abnormal uterine bleeding. Histopathologically, there were 175 (82.94% EPs, 29 (13.74% EPs with hyperplasia without atypia, 5 (2.37% EPs with atypical hyperplasia, and 2 (0.95% EPs with endometrial carcinoma. Contrary to the patients with EPs and EPs with hyperplasia without atypia (group A, patients who had EPs with atypical hyperplasia and EPs with carcinoma (group B were older (p < 0.05, and more commonly postmenopausal (p < 0.05 and with hypertension (p < 0.05, all of statistical significance. Conclusion. The prevalence of endometrial polyps in patients with abnormal uterine bleeding according to our data was 21.95%. Atypical hyperplasia and endometrial carcinoma were rarely confined to a polyp. Older age, postmenopausal period and hypertension may increase the risk of premalignant and malignant changes in endometrial polyps.

    Patients and Method: At Jena University, Department of Radiotherapy, from 1981 to 1990 108 patients with endometrical carcinoma were postoperatively treated with high dose radiation brachytherapy of the vagina without additional percutaneous radiotherapy. Histology showed more or less differenciated adenocarcinoma in 90% of all patients, all patients were postoperatively stage I or II without proven lymphatic metastases. Dependent on individual figures patients were distributed to 3 different gorups: group A: 4 x 10 Gy, tissue-thickness of 1 cm (vaginal apex) respectively 0.5 cm (lower vaginal walls); group B: 4 x 10 Gy, tissue thickness of 1 cm (upper vaginal wall); group C: 4 x 10 Gy, tissue-thickness of 0.5 cm (both excluding the lower vaginal walls). Results: Both 3-year survival rates (group A: 96.6%, group B: 96.9%, group C: 97.7%) and tumor relapse rates of the vaginal apex (group A: 0, group B: 3.1%, group C: 2.2%) don't show significant differences. No case of local tumor recurrence was seen in the upper 2/3 of the vagina and the pelvic walls. Late side effects concerning bladder and rectum (grade III to IV, EORTC/RTOG) could be minimized by reducing the treatment volume (group A: 6.8%/12.6%, group B: 6,2%/3.1%, group C: 2.2%/0).

    This hundred and sixteen patients with carcinoma of the maxillary sinus received primary therapy consisting of external beam irradiation alone or in combination with surgery and/or chemotherapy at the Department of Radiology, Tokyo Medical and Dental University Hospital, between 1953 and 1982. In our institution, methods of treating cancer of the maxillary sinus have been changed from time to time and showed different control rates and clinical courses. An actuarial 10-year survival rate of 21% has been obtained by the megavoltage irradiation alone as well as 34% actuarial 10-year survival rate by megavoltage irradiation with surgery. After the introduction of conservative surgery followed by conventional trimodal combination therapy, the local control rate has been improved. The amount of functional, cosmetic, and brain damages have been remarkably decreased by this mode of therapy. The actuarial five year survival rate was 67%. In addition, along with the improvement of the local control rate, the control of nodal and distant organ metastases have been emerging as one of the important contributions to the prognosis of this disease

    To study endometrial histopathology in women presenting with postmenopausal bleeding. A two-year study from January 2003 to December 2004 of 100 cases of postmenopausal bleeding was conducted at Combined Military Hospital, Sialkot. The histopathology of endometrial biopsy specimens was done to find out the causes of postmenopausal bleeding in these ladies. All these 100 patients had confirmed menopause and the average age was 55 years and above. The most common histopathological diagnosis was senile endometrial atrophy (27%), followed by simple cystic hyperplasia in (17%). Three cases of simple cystic hyperplasia had coexistent ovarian tumors. Glandular hyperplasia without atypia was seen in 6% and with atypia in 4%. Other causes were endometritis (13%), endometrial polyps (8%), proliferative phase endometrium (6%) and secretary phase endometrium (5%). Endometrial carcinoma was seen in (6%) cases, (8%) biopsy specimens were non-representative. Although senile endometrial atrophy was most commonly found in these ladies but a significant percentage of endometrial hyperplasia and endometrial cancer implies the need for investigating all cases of postmenopausal bleeding. Bimanual examination and pelvic ultrasonography should be combined with endometrial sampling so that rare pelvic pathologies may not be missed. (author)

    Purpose: To determine the feasibility of pelvic intensity modulated radiation therapy (IMRT) for patients with endometrial cancer in a multi-institutional setting and to determine whether this treatment is associated with fewer short-term bowel adverse events than standard radiation therapy. Methods: Patients with adenocarcinoma of the endometrium treated with pelvic radiation therapy alone were eligible. Guidelines for target definition and delineation, dose prescription, and dose-volume constraints for the targets and critical normal structures were detailed in the study protocol and a web-based atlas. Results: Fifty-eight patients were accrued by 25 institutions; 43 were eligible for analysis. Forty-two patients (98%) had an acceptable IMRT plan; 1 had an unacceptable variation from the prescribed dose to the nodal planning target volume. The proportions of cases in which doses to critical normal structures exceeded protocol criteria were as follows: bladder, 67%; rectum, 76%; bowel, 17%; and femoral heads, 33%. Twelve patients (28%) developed grade {>=}2 short-term bowel adverse events. Conclusions: Pelvic IMRT for endometrial cancer is feasible across multiple institutions with use of a detailed protocol and centralized quality assurance (QA). For future trials, contouring of vaginal and nodal tissue will need continued monitoring with good QA and better definitions will be needed for organs at risk.

    Thickened uterine endometrium with abnormal uterine bleeding highly suggests endometrial hyperplasia or endometrial carcinoma. A case of 35-year-old nulliparous woman came to our department with endometrial mass manifesting as endometrial cancer. Transrectal ultrasonography and magnetic resonance imaging (MRI) showed an 8x6 cm multicystic, ill-defined mass compacted at the uterine endometrium, the anterior wall of the uterus, and 3x3 cm heterogenous mass at the left adnexa. The edometrial mass showed multiple septations with enhancement and low-signal intensity on T2-weighted images. After endometrial biopsy was done and simple hyperplasia without atypia was observed at the histopathologic finding, the patient underwent robot-assisted laparoscopy and diagnosed as adenomyoma at the frozen pathology. After adenomyomectomy, permanent pathologic analysis revealed the same result and she recovered without any complications and responded well to gonadotropin-releasing hormone (GnRH) agonist therapy.

    Purpose: The aim of this study was to evaluate the effectiveness of low-dose-rate brachytherapy for local control and relapse-free survival in squamous cell and basal cell carcinomas of the lips. We compared two groups: one with tumors on the skin and the other with tumors on the lip. Patients and methods: All patients had been treated at Claudius Regaud Cancer Centre from 1990 to 2008 for squamous cell or basal cell carcinoma. Low-dose-rate brachytherapy was performed with iridium 192 wires according to the Paris system rules. On average, the dose delivered was 65 Gy. Results: 172 consecutive patients were included in our study; 69 had skin carcinoma (squamous cell or basal cell), and 92 had squamous cell mucosal carcinoma. The average follow-up time was 5.4 years. In the skin cancer group, there were five local recurrences and one lymph node recurrence. In the mucosal cancer group, there were ten local recurrences and five lymph node recurrences. The 8-year relapse-free survival for the entire population was 80%. The 8-year relapse-free survival was 85% for skin carcinoma 75% for mucosal carcinoma, with no significant difference between groups. The functional results were satisfactory for 99% of patients, and the cosmetic results were satisfactory for 92%. Maximal toxicity observed was Grade 2. Conclusions: Low-dose-rate brachytherapy can be used to treat lip carcinomas at Stages T1 and T2 as the only treatment with excellent results for local control and relapse-free survival. The benefits of brachytherapy are also cosmetic and functional, with 91% of patients having no side effects.

    Endometrial carcinoma (EC) is the most common gynecologic malignancy with increasing morbidity in recent years. MicroRNAs (miRNAs), a type of non-coding RNA, have been proven to be critical in the process of tumorigenesis. miR-424 has been reported to play a protective role in various type of cancer including endometrial carcinoma. It has been reported that high levels of estrogen increase morbidity of EC by promoting cell growth ability. The current research was designed to delineate the mechanism of miR-424 in regulating E2 (17β-estradiol)-induced cell proliferation in endometrial cancer. In this study, we confirmed that cell proliferation is increased significantly in E2-treated endometrial cancer cell lines. Moreover, miR-424 overexpression dramatically decreased E2-induced cell proliferation, indicating a pivotal role in endometrial cancer cell growth. In addition, the results suggest that miR-424 up-regulation inactivated the PI3K/AKT signaling, which was mediated by G-protein-coupled estrogen receptor-1 (GPER) in endometrial cancer. Furthermore, the luciferase report confirmed the targeting reaction between miR-424 and GPER. After transfection with the GPER overexpression vector into E2-induced endometrial cancer cells, we found that GPER significantly attenuated the inhibition effect of miR-424 in E2-induced cell growth in EC. Taken together, our study suggests that increased miR-424 suppresses E2-induced cell growth, and providing a potential therapeutic target for estrogen-associated endometrial carcinoma.

    To describe the sonohysterographic findings of endometrial abnormalities, and to determine the usefulness of sonohysterography (SH) for predicting endometrial abnormalities in women with polycystic ovarian disease(PCOD). 82 patients with PCOD who had vaginal bleeding or endometrial thickening and lesion mass on baseline transvaginal sonography were prospectively examined with SH. The SH findings were evaluated for endometrial thickness, the presence of endometrial thickening and lesion mass, echogenicity and surface contour, distensibility of the endometrial cavity, and disruption of endometrial-myometrial interface. These findings were compared with the pathologic findings and the diagnostic accuracy of SH for predicting endometrial abnormalities was assessed. Endometrial abnormalities were identified in 47 (57.3%) of 82 PCOD patients, and their pathologic diagnosis included endometrial carcinoma in 7 cases, hyperplasia in 19 cases (atypical hyperplasia, n=5), and polyp in 21 cases. Of the 35 patients who did not have endometrial abnormalities, there was disordered proliferative endometrium in 18 cases and normal proliferative or secretory endometrium in 17 cases. The SH findings of endometrial carcinoma were endometrial thickening in 5 cases, endometrial thickening and lesion mass in 2 cases, and the endometrial thickness ranged from 6 mm to 15 mm (mean 9.5 mm). They were characterized as a diffuse polyploid endometrial thickening or a sessile endometrial mass with irregular surface, homogeneous hyperechogenicity, and obliteration of the endometrial cavity. Endometrial hyperplasia appeared as endometrial thickening in 14 cases, endometrial lesion mass in 3 cases, and endometrial thickening and lesion mass in 2 cases, and the endometrial thickness was between 6.5-10.7 mm (mean 8.2 mm). They showed a diffuse uniform endometrial thickening or a polyploid endometrial lesion mass with homogeneous hyperechogenicity and a regular surface. Endometrial polyps appeared as

    Thermal balloon endometrial ablation is a new operative technique recently proposed in the treatment of dysfunctional uterine bleeding. To evaluate the efficacy of thermal balloon endometrial ablation in the treatment of dysfunctional uterine bleeding, and to identify the possible predictive factors for a successful outcome. A prospective study was conducted including 152 patients with chronic abnormal uterine bleeding refractory to medical treatment. All patients were treated by thermal balloon endometrial ablation (Thermachoice, Gynecare) between January 1, 1996 and December 31, 2003. patients were included if their uterine cavities sounded to less than 12 cm and had undergone hysteroscopy, pelvic ultrasound and endometrial biopsie showing no structural or (pre) malignant endometrial abnormalities. A balloon catheter was placed through the cervix and after inflation in the endometrial cavity with 5% dextrose in water, was heated to 87 +/- 5 degrees C. No one required cervical dilatation. Balloon pressures were 160 to 170 mm Hg. All patients underwent 8 minutes of therapy. The average patient was 47 years (range: 30-62 years) and was followed for a mean of 3 years and 7 months (range: 6 months - 8 years). 31.6% of women reported amennorhea, 16.5% hypomenorrhea and 21% eumenorrhea. Menorrhagea persisted in 11.2% of patients. No intraoperative complications and minor postoperative morbidity occured in 10.5% of patients. Three prgnancy complicated by spontaneous abortions were reported after the treatment. A total of 78% of women reported overall satisfaction with the endometrial ablation procedure and 18% were dissatisfied. 17.8% of patients underwent hysterectomy within 1 to 5 years of balloon endometrial ablation. Increasing age and menopause were significantly associated with increased odds of success (p < 0.05). Thermal balloon endometrial ablation is a simple, easy, effective, and minimally invasive procedure in menhorragic women with no desire for further

    A total of 25 cases with early gastric carcinoma, of which 10 cases were followed by gastrectomy, were given a combined radiotherapy with 5-Fu, Ft 207 or MFC at Miyagi Seijinbyo Center. Histologic examinations of biopsy specimens revealed the disappearance of cancer cells in five (42%) of 12 cases and those of serial specimens of the resected stomach showed the complete disappearance of cancer cells in three (27%) of 11 lesions (10 cases). Five year survival rate in 15 non-resected cases was only 30%. From these results, it was suggested that a combined radiotherapy of early gastric carcinoma should not be chosen as a curative treatment procedure but it might be valuable, if early carcinoma was thought to be inoperable because of other medical reasons.

    Full Text Available Abstract Background Extracellular matrix metalloproteinase inducer (Emmprin/CD147 is a transmembrane glycoprotein that belongs to the immunoglobulin superfamily. Enriched on the surface of many tumor cells, emmprin promotes tumor growth, invasion, metastasis and angiogenesis. We evaluated the clinical importance of emmprin and investigated its role in endometrial cancer. Methods Emmprin expression was examined in uterine normal endometrium, endometrial hyperplasia and cancer specimens by immunohistochemistry. In addition, the biological functions and inhibitory effects of an emmprin knockdown were investigated in HEC-50B and KLE endometrial cancer cell lines. Results The levels of emmprin expression were significantly increased in the endometrial cancer specimens compared with the normal endometrium and endometrial hyperplasia specimens (p p p  Conclusions The present findings suggest that low emmprin expression might be a predictor of favorable prognosis in endometrial cancer patients, and that emmprin may represent a potential therapeutic target for endometrial cancer.

    Cytology of the endometrium is an underused technique in diagnostic pathology. It has been used in the past for endometrial hyperplasia and carcinoma. Only few studies have used cytology in the diagnosis of dysfunctional uterine bleeding (DUB). Endometrial imprint cytology has been rarely used except for application of immunocytochemistry in diagnosis of endometrial carcinoma. The present study was conducted to evaluate whether it is possible to assign histopathology-like diagnosis by imprint cytology and also to evaluate its usefulness in the assessment of patients of dysfunctional uterine bleeding of low clinical suspicion. Imprint smears were made from 93 curettage materials during a study of DUB. Blinded analysis of imprint smears was performed by using McKenzie's criteria and some criteria devised for the requirements of this study. Results of cytology were correlated with histopathology. Statistical analysis was carried out by GraphpadInStat Demo. Majority of the patterns classifiable in histopathology could also be classified in this study on imprint cytology. The overall sensitivity and specificity of cytology in the detection of endometrial patterns in DUB patients were 91.23% and 83.87%, respectively, although the sensitivities and specificities differ according to the phase of endometrium. Histopathology-like categories can be assigned on imprint smears in the diagnosis of DUB. Endometrial imprint cytology can be helpful in centers where histopathology laboratories are not available and even in well-established institutes. It is possible to improve the sensitivity and specificity with better imprinting techniques.

However, the role of hsa-miR-181a in the pathogenesis of endometrial carcinoma (EC and its clinical significance are unclear. This study aimed to search for the molecular targets of hsa-miR-181a using bioinformatic tools and then determine the expression levels of hsa-miR-181a in normal, hyperplasia, and EC samples from humans. To predict the targets of hsa-miR-181a, ten different algorithms were used, including miRanda-mirSVR, DIANA microT v5.0, miRDB, RNA22 v2, TargetMiner, TargetScan 6.2, PicTar, MicroCosm Targets v5, and miRWALK. Two algorithms, TarBase 6.0 and miRTarBase, were used to identify the validated targets of hsa-miR-181a-5p (a mature product of hsa-miR-181a, and the web-based Database for Annotation, Visualization and Integrated ­Discovery (DAVID 6.7 was used to provide biological functional interpretation of the validated targets of hsa-miR-181a-5p.

    Background: Magnetic resonance imaging (MRI) has been frequently used to determine a preoperative treatment plan for gynecologic cancers. However, the MR accuracy for staging an endometrial cancer is not satisfactory based on the old FIGO staging system. Purpose: To evaluate MR accuracy for staging endometrial cancer using the new FIGO staging system. Material and Methods: Between January 2005 and May 2009, 199 women underwent surgery due to endometrial cancer. In each patient, an endometrial cancer was staged using MR findings based on the old FIGO staging system and then repeated according to the new FIGO staging system for comparison. Histopathologic findings were used as a standard of reference. Results: The accuracy of MRI in the staging of endometrial carcinoma stage I, II, III, and IV using the old FIGO staging system were 80% (159/199), 89% (178/199), 90% (179/199), and 99% (198/199), respectively, compared to 87% (174/199), 97% (193/199), 90% (179/199), and 99% (198/199), respectively, when using the new FIGO staging criteria. The overall MR accuracy of the old and new staging systems were 51% (101/199) and 81% (161/199), respectively. Conclusion: MRI has become a more useful tool in the preoperative staging of endometrial cancers using the new FIGO staging system compared to the old one with increased accuracy

    Full Text Available Subcutaneous metastases from endometrial cancer are rare situations, only few cases being described so far. The main incriminated mechanisms leading to the apparition of such lesions include hematogenous and lymphatic spread. We present the case of a 66-year-old patient known with previous history of stage IIIA endometroid endometrial carcinoma initially treated by surgery and adjuvant chemotherapy who developed at 18 months follow-up a distant subcutaneous oligometastasis. At this time the patient was resubmitted to surgery, the lesion being successfully removed. The histopathological result confirmed the endometrial cancer origin of this lesion. Subcutaneous and cutaneous metastases from endometrial cancer are rare eventualities which are usually diagnosed as part of systemic dissemination of this malignancy; in these cases, the patient is only candidate for oncological treatment with palliative intent. In some cases, in which the lesions occur as oligometastatic disease, surgery might be performed with curative intent. In our case the diagnostic of the subcutaneous lesion as oligometastatic disease transformed the patient in a perfect candidate for curative oncological surgery.

    Urethral carcinoma in women is uncommon. This study was undertaken to evaluate the role of radiotherapy in the treatment of these tumors. The hospital records of 34 women with primary urethral carcinoma were retrospectively reviewed. There were 15 squamous cell carcinomas, 13 transitional cell carcinomas, and six adenocarcinomas. The primary tumor was >4 cm in size in eight patients, involved the proximal urethra in 19 and extended to adjacent organs in 22. Inguinal or iliac lymphadenopathy was present in nine patients. There were eight TNM stage I/II tumors, 11 stage III tumors and 15 stage IV tumors. Radiotherapy was administered only to the primary tumor in 15 patients, and to the primary tumor and regional lymph nodes in the remaining 19 patients. Brachytherapy with or without external radiation was used to treat the primary tumor in 20 patients. Tumor recurred in 21 patients. The 7-year actuarial overall and cause-specific survivals were 41 and 45%, respectively. Large primary tumor bulk and treatment with external beam radiation alone (no brachytherapy) were independent adverse prognostic factors for local tumor recurrence. Brachytherapy reduced the risk of local recurrence by a factor of 4.2. The beneficial effect of brachytherapy was most prominently seen in patients with bulky primary disease. Large tumor size was the only independent adverse predictor of overall disease recurrence and death from cancer. Radiotherapy is an effective treatment for carcinoma of the female urethra and preserves normal anatomy and function. Brachytherapy improves local tumor control, possibly as a result of the higher radiation dose that can safely be delivered. (author)

    Lynch syndrome is an autosomal dominant inherited disease caused by germline mutations in mismatch repair genes. Analysis for microsatellite instability (MSI) and immunohistochemistry (IHC) of protein expressions of disease-associated genes is used to screen for Lynch syndrome in endometrial cancer patients. When losses of both MLH1 and PMS2 proteins are observed by IHC, MLH1 promoter methylation analysis is conducted to distinguish Lynch syndrome-associated endometrial cancer from sporadic cancer. Here we report a woman who developed endometrial cancer at the age of 49 years. She had a family history of colorectal cancer (first-degree relative aged 52 years) and stomach cancer (second-degree relative with the age of onset unknown). No other family history was present, and she failed to meet the Amsterdam II criteria for the diagnosis of Lynch syndrome. Losses of MLH1 and PMS2, but not MSH2 and MSH6, proteins were observed by IHC in endometrial cancer tissues. Because MLH1 promoter hypermethylation was detected in endometrial cancer tissue samples, the epigenetic silencing of MLH1 was suspected as the cause of the protein loss. However, because of the early onset of endometrial cancer and the positive family history, a diagnosis of Lynch syndrome was also suspected. Therefore, we provided her with genetic counseling. After obtaining her consent, MLH1 promoter methylation testing and genetic testing of peripheral blood were performed. MLH1 promoter methylation was not observed in peripheral blood. However, genetic testing revealed a large deletion of exon 5 in MLH1; thus, we diagnosed the presence of Lynch syndrome. Both MLH1 germline mutation and MLH1 promoter hypermethylation may be observed in endometrial cancer. Therefore, even if MLH1 promoter hypermethylation is detected, a diagnosis of Lynch syndrome cannot be excluded.

    Full Text Available Mitotane (o,p'-DDD acts mainly as an inhibitor of intramitochondrial pregnenolone and cortisol synthesis. Its adrenolytic effect depends on metabolic activation due to conversion to o,p'-DDA and o,p'-DDE. The drug has been used for 40 years in the treatment of adrenocortical carcinoma, mainly its regional and metastatic stage, as an adjuvant to surgical resection of the tumor. In the medical literature there are controversial opinions about its efficacy for the treatment of adrenocortical carcinoma. In our experience, mitotane administered immediately after surgery appeared to be much more efficient than when administered later. We have administered this drug in all cases of microscopically confirmed adrenocortical carcinoma, irrespectively of stage at the time of surgery, for fear of a false too optimistic classification. In our series of 82 patients with adrenocortical carcinoma, 59 patients have been treated with mitotane, 32 of them immediately after surgery, and 27 with a delay of 2 to 24 months. Today there are 18 survivors in the group of patients treated with mitotane soon after the operation and only 6 survivors in the group receiving mitotane with a delay. All patients were simultaneously given replacement therapy. Undesired effects of mitotane administration included increased aminotransferase and alkaline phosphatase activity, decreased white cell, platelet or red cell number, and myasthenia. Furthermore, we used mitotane with good results in Cushing's syndrome of non-malignant origin as pre-treatment before surgery or in long-term treatment for patients with poor tolerance of other adrenal inhibitors.

    Purpose: To retrospectively evaluate the outcome after radical radiotherapy (RT) and surgical salvage and assess the risk of late toxicity for patients with primary subglottic squamous cell carcinoma treated at our center. Methods and Materials: Between 1971 and 1996, 43 patients with primary squamous cell carcinoma of the subglottis (35 men, 8 women) were treated with radical RT. All received megavoltage irradiation, most commonly to a dose of 50-52 Gy in 20 fractions during 4 weeks (39 patients). The median follow-up was 4.2 years. Results: Local control was achieved with RT alone in 24 (56%) of the 43 patients: 7 of 11 with T1, 8 of 12 with T2, 4 of 8 with T3, and 5 of 12 with T4. The 5-year actuarial local relapse-free rate was 52%. Subsequent local control was achieved in 11 of the 13 patients with failed RT and attempted surgical salvage, for an ultimate local control rate of 81.4% (35 of 43). The 5-year overall and cause-specific actuarial survival rate was 50.3% and 66.9%, respectively. No patients developed Grade 3 or 4 late radiation morbidity. Conclusion: These data support the use of primary RT in the treatment of patients with primary squamous cell carcinoma of the subglottis as an appropriate treatment approach providing an option for laryngeal conservation

    To analyze various parameters affect local control, we reviewed the results of radiotherapy for early glottic carcinoma. Between 1977 and 1997, 64 patients with untreated early glottic carcinoma and four patients with recurrent early glottic carcinoma were analyzed retrospectively. All tumors were classified as follows; T1 (n=56), T2 (n=12); well differentiated (n=33), moderately (n=25), poorly (n=1), unknown (n=9); very small tumor (VST) (n=46), small tumor (ST) (n=22). All patients were treated utilizing a cobalt-60 unit to a total dose that ranged from 56 Gy to 64 Gy (mean 60 Gy). The mean treatment time was 44 days (range 38-49). The local control rates at 2 years and 5 years for all patients were 85% and 78%, respectively. On univariate analysis, tumor size (p=0.0146) and recurrent or untreated tumor (p=0.0226) affected local control. On multivariate analysis, tumor size (p=0.0273) and recurrent or untreated tumor (p=0.0495) were also significant factors that affected local control. (author)

    We aimed to investigate the association of metabolic syndrome and metabolic risk factors with endometrial hyperplasia and carcinoma among women with abnormal uterine bleeding (AUB). This study included 199 patients who had undergone endometrial curettage due to abnormal uterine bleeding. We divided the patients into two groups according to whether they had an abnormal (n = 53) or normal endometrium (n = 146). Waist circumference, blood pressure, fasting glucose and serum lipid levels were measured and statistically analyzed. The women in each group were matched with regard to mean age, gravidity, parity and menopausal status. We found increased prevalence of metabolic syndrome, diabetes, general and abdominal obesity, hypertension, elevated levels of glucose, total cholesterol and LDL-cholesterol and reduced levels of HDL-cholesterol among women with endometrial carcinoma and hyperplasia. These results were detected particularly in postmenopausal (>50 years) women compared to pre-menopausal cases (<50 years). All metabolic parameters were similar between hyperplasia and cancer groups. Metabolic syndrome and its components have been shown to have profound impacts on initiation and progession of endometrial pathology, particularly during post-menopausal period.

    To investigate the effect of mutant-type [(12)Asp]K-ras4B gene on the expression of estrogen receptor (ER) alpha and beta and their transcriptional activity as a transcription factor in endometrial carcinoma HEC-1A cell line. (1) Effect of [(12)Asp]K-ras4B on the expression of ER alpha and beta were determined using Western blot assay. (2) Eukaryotic expression plasmid pGL3-luciferase-ERE containing luciferase report gene and estrogen receptor element (ERE) was constructed, and co-transfected into NIH3T3 and HEC-1A cell lines with pEGFP-N1 to examine the effect of [(12)Asp]K-ras4B on ER transcription that is regulated by estradiol. In addition, they were transfected into pSV5-HER0 (containing full length wide type ERalpha cDNA) and pCMV-rafS621A (inhibiting raf kinase) plasmids to test the effect of [(12)Asp]K-ras4B/raf signal pathway on transcriptional activity of ER proteins. (1) Protein level of ERs expressed in pcDI transfected control cells was low while it was increased for 3.6-fold (97 +/- 25, 349 +/- 67, P ras4B NIH3T3 cells after transfection. (2) In pcDI-[(12)Asp]K-ras4B NIH3T3 cells, the ratios for ERalpha and and ERbeta levels before transfection of rafS621A plasmids to that after the transfection, were 2.4:1 (724 +/- 45, 310 +/- 46, P HEC-1A cells, these ratios were 2.1:1 (566 +/- 22, 279 +/- 30, P ras4B NIH3T3 cells, 19-fold (141 +/- 39, 2644 +/- 331, P HEC-1A cells, respectively, when compared with those in the absence of E(2). (4) In pSV5-HER0 transfected pcDI-[(12)Asp] K-ras4B NIH3T3 cells and HEC-1A cells, compared to the untransfected cells, the ER transcriptional activity in the transfected cells increased markedly. The luciferase activity was increased for 8-fold (1048 +/- 91, 8099 +/- 452, P HEC-1A cells and pcDI-[(12)Asp]K-ras4B NIH3T3 cells. The ratio of luciferase activities in pcDI-[(12)Asp]K-ras4B NIH3T3 and HEC-1A cells, before and after transfection was 7.8:1 (1184 +/- 168, 152 +/- 27, P ras4B can enhance the expression of ERalpha and

    Full text: Aim: Cell membrane-specific somatostatin receptors are usually expressed by neuroendocrine tumors. Radiolabelled receptor-binding somatostatin analogues target tissues expressing these receptors and can be used for visualization and treatment. After the localization of tumors bearing somatostatin receptors with 111In or 99mTc labeled somatostatin analogues, in the case of high tumor uptake related to non target tissues, different radioisotopes have been used for their treatment. Thus, application of high doses of 111In- DTPA-octreotide had an impact on improvement of the clinical symptoms, without significant reduction of the tumor mass. However, 90Y somatostatin analogues (DOTA TOC, lanreotide) may be more effective for reduction of the tissue of the larger tumors while 177Lu labeled ones may be applied in smaller tumors. Combination of both of them seems to be the most effective therapy, particularly in tumors bearing both small and large lesions. The aim of this work is presentation of the preliminary results of the therapy of NETs with another octreotide analogue, 90Y DOTA TATE, which so far has been proved to have high therapeutic potential when labeled with 177Lu. Patients and methods: We investigated 7 patients with neuroendocrine tumors (two patients had neuroendocrine pancreatic carcinomas with liver metastases (one of them had metastases in peritoneal lymph nodes), one patient with operated (resected) bronchial carcinoid and liver metastases, three patients with neuroendocrine carcinomas of unknown origin and hepatic metastases (one with skeletal metastases) and one with pancreatic gastrinoma without metastases (surgery was impossible to perform). In all of them, together with other laboratory analyses and imaging methods, scintigraphy with somatostatin analogues was performed (in 3 with 111In Octreoscan and in the other 4 with 99mTc HYNIC TOC) and high tumor uptake was observed. The therapy was performed with 2- 4,5 GBq 90Y DOTA TATE per

    Body mass index (BMI) is a major risk factor for endometrial cancer incidence but its impact on post-treatment survival is unclear. We investigated the relationships of BMI (categorised using the WHO definitions) with clinico-pathological characteristics and outcome in women treated within the MRC ASTEC randomised trial, which provides data from patients who received standardised allocated treatments and therefore reduces biases. The impact of BMI on both recurrence-free survival (RFS) and overall survival (OS) was analysed using the Cox regression models. An apriori framework of evaluating potential biases was explored. From 1408 participants, there were 1070 women with determinable BMI (median=29.1 kg/m(2)). Histological types were endometrioid (type 1) in 893 and non-endometrioid (type 2) in 146 women; the proportion of the latter decreasing with increasing BMI (8% versus 19% for obese III WHO category versus normal weight, p(trend)=0.003). For type 1 carcinomas, increasing BMI was associated with less aggressive histopathological features (depth of invasion, p=0.006; tumour grade, p=0.015). With a median follow-up of 34.3 months, there was no influence of BMI on RFS - adjusted HRs per 5 kg/m(2) were 0.98 (95% CI 0.86, 1.13) and 0.95 (0.74, 1.24), for type 1 and 2 carcinomas; and no influence on OS - adjusted HRs per 5 kg/m(2) were 0.96 (0.81, 1.14) and 0.92 (0.70, 1.23), respectively. These findings demonstrate an important principle: that an established link between an exposure (here, obesity) and increased incident cancer risk, does not necessarily translate into an inferior outcome following treatment for that cancer.

    The endometrial cavity may demonstrate various imaging manifestations such as normal, reactive, inflammatory, and benign and malignant neoplasms. We evaluated usual and unusual magnetic resonance imaging (MRI) findings of the uterine endometrial cavity, and described the diagnostic clues to differential diagnoses. Surgically proven pathologies of the uterine endometrial cavity were evaluated retrospectively with pathologic correlation. The pathologies included benign endometrial neoplasms such as endometrial hyperplasia and polyp, malignant endometrial neoplasms such as endometrial carcinoma and carcinosarcoma, endometrial-myometrial neoplasm such as endometrial stromal sarcoma, pregnancy-related lesions in the endometrial cavity such as gestational trophoblastic diseases (hydatidiform mole, invasive mole and choriocarcinoma) and placental polyp, myometrial lesions simulating endometrial lesions such as submucosal leiomyoma and some adenomyosis, endometrial neoplasms simulating myometrial lesions such as adenomyomatous polyp and endometrial lesions arising in the hemicavity of a septate/bicornate uterus, and fluid collections in the uterine cavity (hydro/hemato/pyometra). It is important to recognize various imaging findings in these diseases, in order to make a correct preoperative diagnosis. (orig.)

    Extracellular matrix metalloproteinase inducer (Emmprin/CD147) is a transmembrane glycoprotein that belongs to the immunoglobulin superfamily. Enriched on the surface of many tumor cells, emmprin promotes tumor growth, invasion, metastasis and angiogenesis. We evaluated the clinical importance of emmprin and investigated its role in endometrial cancer. Emmprin expression was examined in uterine normal endometrium, endometrial hyperplasia and cancer specimens by immunohistochemistry. In addition, the biological functions and inhibitory effects of an emmprin knockdown were investigated in HEC-50B and KLE endometrial cancer cell lines. The levels of emmprin expression were significantly increased in the endometrial cancer specimens compared with the normal endometrium and endometrial hyperplasia specimens (p emmprin expression were significantly higher than those of patients with low emmprin expression (DFS: p Emmprin knockdown by the siRNA led to cell proliferation, migration and invasion through TGF-β, EGF, NF-κB, VEGF, MMP-2, and MMP-9 expression, which in turn resulted in increased levels of E-cadherin and reduced levels of Vimentin and Snail in endometrial cancer. The present findings suggest that low emmprin expression might be a predictor of favorable prognosis in endometrial cancer patients, and that emmprin may represent a potential therapeutic target for endometrial cancer.

    Molecular alterations preceding endometrial and ovarian cancer and the sequence of events are unknown. Consecutive specimens from lifelong surveillance for Lynch syndrome provides a natural setting to address such questions. To molecularly define the multistep gynecological tumorigenesis, DNA mismatch repair gene mutation carriers with endometrial or ovarian carcinoma or endometrial hyperplasia were identified from a nation-wide registry and endometrial biopsy specimens taken from these individuals during 20 years of screening were collected. A total of 213 endometrial and ovarian specimens from Lynch syndrome individuals and 197 histology-matched (non-serous) samples from sporadic cases were available for this investigation. The specimens were profiled for markers linked to endometrial and ovarian tumorigenesis, including ARID1A protein expression, mismatch repair status, and tumor suppressor gene promoter methylation. In Lynch syndrome-associated endometrial and ovarian carcinomas, ARID1A protein was lost in 61-100% and mismatch repair was deficient in 97-100%, compared to 0-17% and 14-44% in sporadic cases (P = 0.000). ARID1A loss appeared in complex hyperplasia and deficient mismatch repair and tumor suppressor gene promoter methylation in histologically normal endometrium. Despite quantitative differences between Lynch syndrome and sporadic cases, ARID1A expression, mismatch repair, and tumor suppressor gene promoter methylation divided endometrial samples from both patient groups into three categories of increasing abnormality, comprising normal endometrium and simple hyperplasia (I), complex hyperplasia with or without atypia (II), and endometrial cancer (III). Complex hyperplasias without vs. with atypia were molecularly indistinguishable. In conclusion, surveillance specimens from Lynch syndrome identify mismatch repair deficiency, tumor suppressor gene promoter methylation, and ARID1A loss as early changes in tumor development. Our findings are

    The incidence of post-operative complications and treatment results of 60 cases of hypopharynx carcinoma receiving laryngo-pharyngo-esophagectomy followed by reconstruction with jejunum after chemoradiotherapy (CRT) from 1997 to 2006 in 6 hospitals was analyzed. The overall complication rate was 57%. There were 3 cases with carotid artery rupture (5%), 4 with jejunum necrosis (6%), 6 with major salivary fistula (10%), 8 with minor salivary fistula (13%), 8 with abscess alone (13%), 3 with trachea stoma necrosis (5%), and 3 with skin flap necrosis (5%). The death rate due to surgical complications was 3% (2/60). When the cases were divided into two groups, namely the cases with fistula and the cases without fistula, the number of days that permitted drinking was 18.1 in the latter and 81.8 in the former. The 5-year overall survival rate among all cases was 37%. We found that salvage surgery after CRT was effective for recurrent cases. These findings suggest that reconstruction with jejunum is a suitable type of operation with better surgical results. Care is required to reduce the incidence of post-operative complications.

    The purpose of the present paper was to review the results of treating early stages glottic, squamous cell carcinoma by radiotherapy in the Department of Radiation Oncology, Prince of Wales Hospital, Sydney. A retrospective review was carried out of all patients seen in the department from 1967 to 1994, inclusive. To be eligible, patients had to have newly diagnosed cancer and to have been treated with curative intent by radiotherapy alone. Three hundred and sixty-nine patients satisfied the eligibility requirements. The mean follow-up time was 12.2 years (maximum: 28 years). At 5 years the actuarial local control rate was 80% (84% for stage T 1 and 72% for T 2 ). The ultimate local control rate was 96%. The overall survival rates at 5 and 10 years were 73% and 52%, respectively. The risk of nodal recurrence was much higher after persisting disease or local recurrence. Our results confirm the high cure rates achieved with this modality of treatment and are comparable with those reported in the literature. Copyright (1999) Blackwell Science Pty. Ltd

  7. Endometrial haemostasis and menstruation.

    Under normal physiological circumstances menstruation is a highly regulated, complex process that is under strict hormonal control. During normal menstruation, progesterone withdrawal initiates menstruation. The cessation of menstrual bleeding is achieved by endometrial haemostasis via platelet aggregation, fibrin deposition and thrombus formation. Local endocrine, immunological and haemostatic factors interact at a molecular level to control endometrial haemostasis. Tissue factor and thrombin play a key role locally in the cessation of menstrual bleeding through instigation of the coagulation factors. On the other hand, fibrinolysis prevents clot organisation within the uterine cavity while plasminogen activator inhibitors (PAI) and thrombin-activatable fibrinolysis inhibitors control plasminogen activators and plasmin activity. Abnormalities of uterine bleeding can result from imbalance of the haemostatic factors. The most common abnormality of uterine bleeding is heavy menstrual bleeding (HMB). Modern research has shown that an undiagnosed bleeding disorder, in particular von Willebrand disease (VWD) and platelet function disorders, can be an underlying cause of HMB. This has led to a change in the approach to the management of HMB. While full haemostatic assessment is not required for all women presenting with HMB, menstrual score and bleeding score can help to discriminate women who are more likely to have a bleeding disorder and benefit from laboratory haemostatic evaluation. Haemostatic agents (tranexamic acid and DDAVP) enhance systemic and endometrial haemostasis and are effective in reducing menstrual blood loss in women with or without bleeding disorders. Further research is required to enhance our understanding of the complex interactions of haemostatic factors in general, and specifically within the endometrium. This will lead to the development of more targeted interventions for the management of abnormal uterine bleeding in the future.

    The methods and results of treatment for cancer of the cervical esophagus differ from those for cancer of the thoracic esophagus. Our objective was to retrospectively review the outcome for cervical esophageal cancer patients treated with radiotherapy. Twenty-seven patients with carcinoma of the cervical esophagus treated with definitive radiotherapy from 1988 to 2002 were enrolled in the study. Clinical stage (UICC 1997) was stage I in five, II in six, III in 12 and IV in four. Concurrent head and neck malignancy was found in six patients (22%). The mean radiation dose was 66 Gy. Concurrent chemotherapy (cisplatin and 5-fluorouracil) was performed in 23 patients. The actuarial overall survival rates at 1, 3 and 5 years were 55.6%, 37.9% and 37.9%, respectively, with a median survival of 13.9 months. In the patients with stage I, the 3-year and 5-year survival rates were 75% and 75%, respectively. With univariate analysis, only two of the possible prognostic factors were found to actually influence survival: performance status (p<0.01) and tumor length (p<0.01). The survival of patients with cervical esophageal cancer remains poor. It is thought that organ preservation is possible by definitive chemoradiation for early cancer

    Full Text Available Type II endometrial carcinoma typically exhibits aggressive metastasis and results in a poor prognosis. Siegesbeckia orientalis Linne is a traditional Chinese medicinal herb with several medicinal benefits, including the cytotoxicity against various cancers. This study investigates the inhibitory effects of S. orientalis ethanol extract (SOE on the migration and invasion of endometrial cancer cells, which were stimulated by transforming growth factor β (TGFβ. The inhibitory effects were evaluated by determining wound healing and performing the Boyden chamber assay. This study reveals that SOE can inhibit TGFβ1-induced cell wound healing, cell migration, and cell invasion in a dose-dependent manner in RL95-2 and HEC-1A endometrial cancer cells. SOE also reversed the TGFβ1-induced epithelial-mesenchymal transition, including the loss of the cell-cell junction and the lamellipodia-like structures. Western blot analysis revealed that SOE inhibited the phosphorylation of ERK1/2, JNK1/2, and Akt, as well as the expression of MMP-9, MMP-2, and u-PA in RL95-2 cells dose-dependently. The results of this investigation suggest that SOE is a potential anti-metastatic agent against human endometrial tumors.

    A 59-year-old woman was admitted to the hospital with a one-month history of hemoptysis, generalized fatigue, and a high fever. A chest X-ray film obtained on admission showed a massive right-sided pleural effusion. Examination of an aspirate showed a high level of amylase, and bacteria that were the same as oral bacteria. Closed drainage yielded ichorous pus and food residues, which led us to the diagnosis of empyema caused by esophageal perforation. Esophagography and fiberoptic esophagoscopy revealed that an esophagobronchial fistula related to an advanced esophageal carcinoma had caused the empyema. Surgical resection was done, and the patient was alive at the time of this writing, 7 months after she was first treated. Esophageal carcinoma is sometimes accompanied by esophagobronchial fistula. Patients with this condition usually have severe respiratory symptoms; those presenting with empyema are rare. Esophageal carcinoma must be carefully ruled out as the cause of empyema.

    Purpose : Patients with cervical cancer who have positive resection margins after radical hysterectomy are at increased risk for local recurrence. The results of postoperative pelvic radiotherapy for cervix cancer with positive resection margins were analyzed to evaluated the role of radiotherapy. Materials and Methods : Between 1979 and 1992, 60 patients of cervix carcinoma were treated with postoperative radiotherapy after radical hysterectomy because of positive vaginal(48 patients) or parametrial resection margins(12 patients). Patients were treated with external beam radiation therapy(EBRT) alone (12 patients) or EBRT plus vaginal ovoid irradiation (VOI) (48 patients). The median follow-up period was 5 months. Results : The 5-year actuarial disease free and overall survival rates for all patients were 75.2%, 84.1%, respectively. The overall recurrence rate was 23%(14/60). In 48 patients with positive vaginal resection margins, the pelvic recurrence was 8%(4/48). Distant metastasis was 15%(7/48). Of the 43 patients with positive vaginal resection margins treated with EBRT and VOI, recurrence rate was 21%(9/43), while recurrence rate was 40%(2/5) in the EBRT only treated group. In 12 patients with positive parametrial margins, three patients (25%) had distant metastases. The most significant prognostic factor was lymph node metastasis. Complications resulting from radiotherapy occurred at a rate of 32%(19/60) and grade III complications occurred in three patients (5%). Conclusion : Postoperative radiotherapy can produce excellent pelvic control rates in patients with positive resection margins. In patients with positive vaginal margins, whole pelvic EBRT and BOI is recommended

    Purpose: Nasopharyngeal carcinoma (NPC) has a bimodal age distribution. In contrast to the adult variant, little is known about the juvenile form. This study examined the treatment results between adult (aNPC) and juvenile NPC (jNPC) patients for future treatment considerations in jNPC. Methods and Materials: The jNPC population included 53 patients treated at two institutions between 1972 and 2004. The aNPC population included 84 patients treated at one institution. The patients had received a median dose of 66 Gy of external beam radiotherapy and 72% underwent chemotherapy. The mean follow-up for surviving patients was 12.6 years for jNPC and 6.6 years for aNPC. Results: The jNPC patients presented with more advance stages than did the aNPC patients (92% vs. 67% Stage III-IV, p = .006). However, jNPC patients had significantly better overall survival (OS) than did aNPC patients. The 5-year OS rate was 71% for jNPC and 58% for aNPC (p = .03). The jNPC group also demonstrated a trend for greater relapse-free survival than the aNPC group (5-year relapse-free survival rate, 69% vs. 49%; p = .056). The pattern of failure analysis revealed that the jNPC patients had greater locoregional control and freedom from metastasis but the differences were not statistically significant. Univariate analysis for OS revealed that age group, nodal classification, and chemotherapy use were significant prognostic factors. Age group remained significant for OS on multivariate analysis, after adjusting for N classification and treatment. Conclusion: Despite more advance stage at presentation, jNPC patients had better survival than did aNPC patients. Future treatment strategies should take into consideration the long-term complications in these young patients.

    The subject of this work is the therapeutic success of radiation therapy, respectively operation, with uterine carcinoma. For the evaluation 938 patients of the Marburg University Radiation Clinic from the years 1960 to 1979 were included. The 5-year survival rate with collum carcinoma was 56.99% (stage I 79.62%, II 57.29%, III 31.13%, IV 5.88%). With patients with corpus carcinoma the 5-year survival rate was 74.27% (stage II 80.79%, I 77.50%, III 57.50%, IV 30.00%). The results of various radiotherapeutic methods ('Duesseldorf method', 'Marburg method') were discussed. With respect to the international results published in 'Annual Report' the Marburg results for the treatment of collum carcinoma (the 5-year survival rates) are at world level, and the successes in the treatment of corpus carcinoma are clearly better.

    Full Text Available BACKGROUND Abnormal Uterine Bleeding (AUB is one of the most common menstrual complaints and a frequent indication for hysterectomy. It can be a manifestation of any number of pathological entities. Causes of AUB ranges from organic pathologies like leiomyoma, polyps, adenomyosis and malignancy to conditions like coagulopathy and drug-induced AUB and aetiologies vary in different age groups. Histopathological evaluation of endometrium is very vital to identify the cause of AUB. The objectives of this study are to, 1. To evaluate the endometrial histopathology in AUB, and 2. To estimate the incidence of endometrial polyp in AUB. MATERIALS AND METHODS This is a prospective study carried out on 120 women who presented with AUB. Endometrial samples collected were analysed for their histopathological pattern. RESULTS Out of 120 endometrial samples analysed among women of 30-39 years, proliferative endometrium was seen in 43.3% and secretory endometrium in 33.3% and endometrial polyp in 13.3%. In women of 40-49 years, proliferative endometrium in 36.8%, secretory endometrium in 30.9% and disordered proliferative endometrium was seen in 19% of women. The incidence of endometrial polyp was found to be 8.3% in our study. CONCLUSION There is an age-specific relation of abnormal endometrial histopathology. Among abnormal endometrial pathology, disordered proliferative endometrium was more common in perimenopausal age group and endometrial polyps in reproductive age group. The results of this study indicate that benign endometrial histopathology is common in AUB suggesting a role for more conservative therapeutic strategies.

    Full Text Available We performed RNA-seq on an Illumina platform for 7 patients with endometrioid endometrial carcinoma for which both tumor tissue and adjacent noncancer tissue were available. A total of 66 genes were differentially expressed with significance level at adjusted p value < 0.01. Using the gene functional classification tool in the NIH DAVID bioinformatics resource, 5 genes were found to be the only enriched group out of that list of genes. The gene IGSF9 was chosen for further characterization with immunohistochemical staining of a larger cohort of human endometrioid carcinoma tissues. The expression level of IGSF9 in cancer cells was significantly higher than that in control glandular cells in paired tissue samples from the same patients (p=0.008 or in overall comparison between cancer and the control (p=0.003. IGSF9 expression is higher in patients with myometrium invasion relative to those without invasion (p=0.015. Reanalysis of RNA-seq dataset from The Cancer Genome Atlas shows higher expression of IGSF9 in endometrial cancer versus normal control and expression was associated with poor prognosis. These results suggest IGSF9 as a new biomarker in endometrial cancer and warrant further studies on its function, mechanism of action, and potential clinical utility.

    At the Radiotherapeutic Department of the Faculty of Medicine in Istanbul, 35 masculine patients with microcellular bronchial carcinoma, limited disease, were treated for two years, i.e. between 1980 and 1981, with a combination of radiotherapy and chemotherapy. Nine out of these patients are tumor-free after at least 46 months, i.e. about four years. This corresponds to a tumor-free survival rate of 25.7%. (orig.) [de

    Small cell carcinoma is a rare malignant tumor of the larynx. Since this lesion was first described, only 58 cases have been reported in the literature. Between December 1985 and March 1992, five patients with small cell carcinoma of the larynx were treated at the Hospital de la Santa Creu i Sant Pau in Barcelona, Spain. One patient was treated with radiation therapy alone, three patients with chemotherapy and radiation therapy, and one patient with surgery, chemotherapy and radiation therapy. Local and distant control was achieved in only one patient who was observed for 12 months after radiation therapy. Four patients died, one of local disease without distant metastasis at 6 months following treatment, one of local and distant disease at 53 months after radiation therapy, and two of distant metastasis without local disease at 22 and 36 months following treatment. In spite of the fact that only one of the five patients presented in this series is alive and free of disease 12 months following treatment, recent published information suggests that chemotherapy and radiotherapy are currently the most effective form of therapy for small cell carcinoma of the larynx. 16 Refs

    Thirty cases with recurrent gastric carcinoma were treated with a combination of high energy x-ray and some anti-cancer drugs at Miyagi Seijinbyo Center between 1967 and 1977. Twenty three cases of them tolerated well such treatment; the irradiated dose was more than 4000 rad without any serious complication. The response of recurrent tumor to irradiation was marked in 11 lesions of 21 local recurrences and 4 metastases of the lymph node. The survival rates of those irradiated more than 4000 rad were 22% at one year, 15% at two years and 5% at three years. The median survival month was 6,9 months. These rates obtained in a combined radiation therapy seemed to be well matched for those reported by other authors in a surgical management of recurrent gastric carcinoma. As a conclusion, it was suggested that a combined radiation therapy with some anticancer drugs should be an effective procedure to prolong the life of a patient of recurrent gastric carcinoma.

    Between 1969 and 1985, 73 patients with maxillary sinus cancers underwent surgical excision and postoperative radiotherapy. The clinical stage distribution by the AJC system was 3T{sub 1}, 16T{sub 2}, 32T{sub 3} and 22 T{sub 4}. Six patients had palpable lymphadenopathy at diagnosis. Surgery for the primary tumor consisted of partial or radical maxillectomy, and if disease stage indicated it, ipsilateral orbital exenteration. This was followed by radiation treatment delivered through a wedge-pair or three-field technique. All but 3 patients received 50-60 Gy in 2 Gy fractions to an isodose line defining the target volume. Elective neck irradiation (ENI) was nor routinely given. Clinically involved nodes were treated with definitive radiotherapy (5 patients) or combined treatment (1 patient). Forty-five patients had no evidence of disease at the last follow-up. The 5-year relapse-free survival for the whole group was 51 percent. The overall local control rate was 78 percent, Patients with larger tumors, particularly if they also had histological signs of nerve invasion, had a higher recurrence rate than others. The overall nodal recurrence rate without ENI was 38 percent for squamous and undifferen-tiated carcinoma, and only 5 for adenoid cystic carcinomas. Therefore, the current recommendation is to deliver elective nodal irradiation routinely to patients with squamous or undifferentiated carcinoma, except for those who have T{sub 1} lesions. Treatment complications were vision impairment, brain and bone necrosis, trismus, hearing loss, and pituitary insufficiency. The incidence of major side effects was determined by disease extent and treatment technique. Many technical refinements were introduced in order to limit the dose to normal tissues in an attempt to reduce the complication rate. To what extent such practice influences the outcome will be determined from subsequent analysis. (author). 23 refs.; 2 figs.; 5 tabs.

    Alterations of mTOR gene expression have been implicated in the pathogenesis of endometrioid endometrial cancer however only few studies explored the cause of increased mTOR activation in this malignancy. miRNAs are small, noncoding RNAs, which were proven to regulated gene expression at the posttranscriptional level. The study aimed to explore deregulation of miRNAs targeting mTOR kinase (miR-99a, miR-100 and miR-199b) as a possible cause of its altered expression in EEC tissues. In addition expression of the three miRNAs was investigated in plasma of EEC patients and was assessed in terms of diagnostic and prognostic utility. We investigated expression of mTOR kinase transcripts in 46 fresh tissue samples. Expression of miR-99a, miR-100 and miR-199b was investigated in the same group of fresh samples, and in additional 58 FFPE sections as well as in 48 plasma samples using qPCR. Relative quantification was performed using experimentally validated endogenous controls. mTOR kinase expression was increased in EEC tissues and was accompanied by decreased expression of all three miRNAs. Down-regulation of the investigated miRNAs was discovered in plasma of EEC patients and miRNA signatures classified EEC tissues (miR-99a/miR-100/miR-199b) and plasma (miR-99a/miR-199b) samples with higher accuracy in comparison to single miRNAs. We also revealed that miR-100 was an independent prognostic marker of overall survival. We conclude that increased expression of mTOR kinase coexists with down-regulation of its targeting miRNAs, which could suggest a new mechanism of mTOR pathway alterations in EEC. In addition, our findings implicate that miRNA signatures can be considered promising biomarkers for early detection and prognosis of endometrioid endometrial carcinoma

    A method is suggested that permits specifying the primary tumor size on the basis of clinical examination of patients with cervix uteri carcinoma. The values of tumor size have been correlated with long-term results of concomitant radiotherapy in 1358 patients with cervix uteri carcinoma. The data obtained have shown that the primary tumor size is a factor that determines to a large extent radiotherapeutic results in patients with cervix uteri carcinoma. The specification of tumor size values makes it possible to considerably lessen prognostic uncertainty of present-day staging classifications. The structure of radiotherapeutic failures also turned out to be closely associated with the primary tumor size

    Obesity is a prominent risk factor for endometrial cancer (EC) and can impede on surgical and hormonal treatments. Markers of EC, estrogen receptor (ER), progesterone receptor (PR), phospho(Ser473)-AKT (pAKT) and 14-3-3 sigma (14-3-3σ) were measured in EC tissues in both the tumor and stroma and grouped by body mass index (BMI). Immunohistochemical scoring of 82 cases of Type 1 and Type II EC tissues revealed a significantly increased tumor expression of ER, PR and 14-3-3σ in women with Type I (BMI PR and 14-3-3σ in the tumor epithelium was significantly higher in Type I than Type II. In particular, Type I EC exhibited significantly increased levels of only PR from patients with BMI > 40 compared to BMI PR, PIK3CA, PTEN and SFN (gene for 14-3-3σ) confirmed increased PR expression in EC of obese women. In conclusion, ER, PR and 14-3-3σ are differentially regulated in Type I compared to Type II EC while PR is dysregulated in obese women with Type I EC. These findings have potential implications for efficacy of progestin treatment in obese women.

    Among a variety of phytocannabinoids, Δ 9 -tetrahydrocannabinol (THC) and cannabidiol (CBD) are the most promising therapeutic compounds. Besides the well-known palliative effects in cancer patients, cannabinoids have been shown to inhibit in vitro growth of tumor cells. Likewise, the major endocannabinoids (eCBs), anandamide (AEA) and 2-arachidonoylglycerol (2-AG), induce tumor cell death. The purpose of the present study was to characterize cannabinoid elements and evaluate the effect of cannabinoids in endometrial cancer cell viability. The presence of cannabinoid receptors, transient receptor potential vanilloid 1 (TRPV1), and endocannabinoid-metabolizing enzymes were determined by qRT-PCR and Western blot. We also examined the effects and the underlying mechanisms induced by eCBs and phytocannabinoids in endometrial cancer cell viability. Besides TRPV1, both EC cell lines express all the constituents of the endocannabinoid system. We observed that at concentrations higher than 5 μM, eCBs and CBD induced a significant reduction in cell viability in both Ishikawa and Hec50co cells, whereas THC did not cause any effect. In Ishikawa cells, contrary to Hec50co, treatment with AEA and CBD resulted in an increase in the levels of activated caspase -3/-7, in cleaved PARP, and in reactive oxygen species generation, confirming that the reduction in cell viability observed in the MTT assay was caused by the activation of the apoptotic pathway. Finally, these effects were dependent on TRPV1 activation and intracellular calcium levels. These data indicate that cannabinoids modulate endometrial cancer cell death. Selective targeting of TPRV1 by AEA, CBD, or other stable analogues may be an attractive research area for the treatment of estrogen-dependent endometrial carcinoma. Our data further support the evaluation of CBD and CBD-rich extracts for the potential treatment of endometrial cancer, particularly, that has become non-responsive to common therapies.

    Full Text Available Abstract Background Lymphadenectomy is debated in early stages endometrial cancer. Moreover, a new FIGO classification of endometrial cancer, merging stages IA and IB has been recently published. Therefore, the aims of the present study was to evaluate the relevance of the sentinel node (SN procedure in women with endometrial cancer and to discuss whether the use of the 2009 FIGO classification could modify the indications for SN procedure. Methods Eighty-five patients with endometrial cancer underwent the SN procedure followed by pelvic lymphadenectomy. SNs were detected with a dual or single labelling method in 74 and 11 cases, respectively. All SNs were analysed by both H&E staining and immunohistochemistry. Presumed stage before surgery was assessed for all patients based on MR imaging features using the 1988 FIGO classification and the 2009 FIGO classification. Results An SN was detected in 88.2% of cases (75/85 women. Among the fourteen patients with lymph node metastases one-half were detected by serial sectioning and immunohistochemical analysis. There were no false negative case. Using the 1988 FIGO classification and the 2009 FIGO classification, the correlation between preoperative MRI staging and final histology was moderate with Kappa = 0.24 and Kappa = 0.45, respectively. None of the patients with grade 1 endometrioid carcinoma on biopsy and IA 2009 FIGO stage on MR imaging exhibited positive SN. In patients with grade 2-3 endometrioid carcinoma and stage IA on MR imaging, the rate of positive SN reached 16.6% with an incidence of micrometastases of 50%. Conclusions The present study suggests that sentinel node biopsy is an adequate technique to evaluate lymph node status. The use of the 2009 FIGO classification increases the accuracy of MR imaging to stage patients with early stages of endometrial cancer and contributes to clarify the indication of SN biopsy according to tumour grade and histological type.

    Histone deacetylase inhibitors such as Vorinostat display anti-neoplastic activity against a variety of solid tumors. Here, we have investigated the anti-tumoral activity of Vorinostat on endometrial cancer cells. We have found that Vorinostat caused cell growth arrest, loss of clonogenic growth and apoptosis of endometrial cancer cells. Vorinostat-induced the activation of caspase-8 and -9, the initiators caspases of the extrinsic and the intrinsic apoptotic pathways, respectively. Next, we investigated the role of the extrinsic pathway in apoptosis triggered by Vorinostat. We found that Vorinostat caused a dramatic decrease of FLIP mRNA and protein levels. However, overexpression of the long from of FLIP did not block Vorinostat-induced apoptosis. To further investigate the role of extrinsic apoptotic pathway in Vorinostat-induced apoptosis, we performed an shRNA-mediated knock-down of caspase-8. Surprisingly, downregulation of caspase-8 alone caused a marked decrease in clonogenic ability and reduced the growth of endometrial cancer xenografts in vivo, revealing that targeting caspase-8 may be an attractive target for anticancer therapy on endometrial tumors. Furthermore, combination of caspase-8 inhibition and Vorinostat treatment caused an enhancement of apoptotic cell death and a further decrease of clonogenic growth of endometrial cancer cells. More importantly, combination of Vorinostat and caspase-8 inhibition caused a nearly complete inhibition of tumor xenograft growth. Finally, we demonstrate that cell death triggered by Vorinostat alone or in combination with caspase-8 shRNAs was inhibited by the anti-apoptotic protein Bcl-XL. Our results suggest that combinatory therapies using Vorinostat treatment and caspase-8 inhibition can be an effective treatment for endometrial carcinomas.

    Full Text Available Endometrial cancer is the most common gynecologic malignancy in the United States, with yearly rates continuing to increase. Most women present with early stage disease; however, advanced disease carries a grave prognosis. As a result, novel therapies are currently under investigation for the treatment of endometrial cancer. These advances include a better understanding of the genetic basis surrounding the development of endometrial cancer, novel surgical therapies, and new molecular targets for the treatment of this disease. This review explores the literature regarding these advancements in endometrial cancer.

    Full Text Available Abstract Background Management of endometrial precancerous lesions has been of much debate due to inconsistencies in their classification, natural history and histologic diagnosis. Endometrial hyperplasia constitutes a wide range of histomorphologic features associated with high intra and interobserver diagnostic variability. Although traditional microscopic diagnosis is by far the most applicable method and the gold standard for histomorphologic diagnosis, digitized image analysis has been used as a powerful adjunct to maximize the histologic data retrieval and to add some detailed objective criteria for correct diagnosis in difficult cases. Methods A series of 100 endometrial curettage specimens with diagnosis of endometrial hyperplasia or well differentiated adenocarcinoma were blindly reviewed by 5 pathologists; their intra and interobserver reproducibility determined and further compared to the objective morphometric data i.e. D-score and volume percent of stroma (VPS. Results The results were assessed using the weighted kappa statistics. Mean intraobserver kappa value was 0.8690 (99.44% agreement. Mean interobserver kappa values by diagnostic category were: simple hyperplasia without atypia: 0.7441; complex hyperplasia without atypia: 0.3379; atypical hyperplasia: 0.3473, and well-differentiated endometrioid carcinoma: 0.6428; with a kappa value of 0.5372 for all cases combined. Interobserver agreement was in substantial rate for simple hyperplasia (SH and well differentiated adenocarcinoma (WDA but was in fair limit for complex hyperplasia (CH and atypical hyperplasia (AH. Intraobserver agreement was almost perfect. The specimens were divided in two groups according to the computerized morphometric analysis: Endometrial Hyperplasia (EH ( D Score ≥ 1 or VPS ≥ 55% and Endometrial Intraepithelial Neoplasia (EIN (D-Score Conclusion It may be necessary to make some revisions in WHO classification for endometrial hyperplasia and

    From 1965 through 1985, 85 patients with carcinoma of the nasopharynx were irradiated with curative intent at the Department of Radiation Therapy, Aichi Cancer Center Hospital. The observed 5-year survival rate was found to be 34 %. Local recurrence was observed in 15 cases, regional lymph node recurrence in 10 cases, local and regional lymph node recurrence in 2 cases and distant metastases in 24 cases. Most manifestations of recurrence appeared within 2 years after treatment. Local recurrence was often observed in the base of skull in patients in advanced stages of their disease (T 3 - 4). The likelihood of a distant metastasis was stronger in patients with a bilateral neck nodes metastases and/or a lower neck metastases. (author)

    To evaluate the predictive factors for treatment response and prognostic factors affecting survival outcomes after concurrent chemoradiotherapy (CCRT) for patients with anal squamous cell carcinoma. Medical records of forty two patients with histologically confirmed analsquamous cell carcinoma, who had complete CCRT between 1993 and 2008, were reviewed retrospectively. Median age was 61.5 years (39-89 years), and median radiotherapy (RT) dose was 50.4 Gy (30.0-64.0 Gy). A total of 36 patients had equal to or less than T2 stage (85.7%). Fourteen patients (33.3%) showed regional nodal metastasis, 36 patients (85.7%) were treated with 5-fluorouracil (5-FU) plus mitomycin, and the remaining patients were treated by 5-FU plus cisplatinum. The median follow--up time was 62 months (2-202 months).The 5-year overall survival, locoregional relapse-free survival, disease-free survival, and colostomy-free survival rates were 86.0%, 71.7%, 71.7%, 78.2%, respectively. Regarding overall survival, the Eastern Cooperative Oncology Group (ECOG) performance status and complete response were found to be significant prognostic factors on univariate analysis. For multivariate analysis, only the ECOG performance status was significant. No significant factor was found for locoregional relapse-free survival or disease-free survival and similarly for treatment response, no significant factor was determined on logistic regression analysis. There were 7 patients who had local or regional recurrences and one patient with distant metastasis. The only evaluable toxicity in all patients was radiation dermatitis of perianal skin (grade 3), which developed in 4 patients (9.5%) and grade 2 in 22 patients (52.4%). This study revealed that patients with a performance score of ECOG 0-1 survived significantly longer than those with a poorer score. Finally, there was no significant predicting factors tested for treatment response.

    Studies focusing on the impact of obesity on survival in endometrial cancer (EC) have reported controversial results and few data exist on the impact of obesity on recurrence rate and recurrence-free survival (RFS). The aim of this study was to assess the impact of obesity on surgical staging and RFS in EC according to the European Society of Medical Oncology (ESMO) risk groups. Data of 729 women with EC who received primary surgical treatment between January 2000 and December 2012 were abstracted from a multicenter database. RFS distributions according to body mass index (BMI) in each ESMO risk group were estimated using the Kaplan-Meier method. Survival was evaluated using the log-rank test, and the Cox proportional hazards model was used to determine influence of multiple variables. Distribution of the 729 women with EC according to BMI was BMI women with a BMI ≥ 35 (72 %) than for those with a BMI obese women in the low-/intermediate-risk groups, but a BMI ≥ 35 was independently correlated to a poorer RFS (hazard ratio 12.5; 95 % confidence interval 3.1-51.3) for women in the high-risk group. Severe obesity negatively impacts RFS in women with high-risk EC, underlining the importance of complete surgical staging and adapted adjuvant therapies in this subgroup of women.

    Full Text Available BACKGROUND Abnormal uterine bleeding is defined as any bleeding not conforming to the normal cyclical pattern as well as to the normal amount and frequency of menstrual cycle. Abnormal uterine bleeding can occur due to gynaecological as well as medical causes. Gynaecological causes include organic and nonorganic factors. It has various clinical presentations such as menorrhagia, polymenorrhagia, metrorrhagia and intermenstrual bleeding. Dilatation and Curettage (D and C is a safe and effective outpatient procedure performed in patients with AUB. It provides endometrial tissue for examination of histological variations of endometrium thus guiding in further management. MATERIALS AND METHODS This is a retrospective study of patients presenting with AUB over a period of one year (2015-2016 done in the Department of Obstetrics and Gynaecology at a tertiary care hospital. 89 patients with complaints of AUB attributable to isolated endometrial cause were included in the study. Patients with AUB due to vaginal, cervical causes, leiomyomas, adnexal pathology, medical causes and complications of pregnancy were excluded from the study. A structured proforma regarding the patient’s complaints, pattern of bleeding, medical, surgical history and a general systemic and pelvic examination was used to evaluate all patients. RESULTS Among all the patients who presented with AUB during the study period, 89 patients were identified to have isolated endometrial pathology as a cause of abnormal uterine bleeding. In our study, age of patients presenting with AUB ranged from 24 years to 70 years. AUB was most commonly seen in the age group of 41-50 years (42.6%. Menorrhagia in 32.5% was the most common presentation of AUB. The commonest histopathological finding was proliferative phase endometrium (25.84% followed by secretory phase endometrium (19.1%. Hyperplasia was observed in 19.1%, which included simple hyperplasia (6.74%, complex hyperplasia without atypia in

    From January 1975 to August 1988, 40 patients with extrahepatic bile duct carcinoma were treated by external irradiation at Chiba University Hospital and the National Medical Center Hospital. Thirty-four patients (male: 20, female: 14) were evaluable. Eighteen patients were postoperative cases because the surgical margin was positive for tumor cells in the postoperative pathological examination; the other 16 were inoperable cases. Survival in postoperative and inoperable cases was not significantly different, with median survival times of 13.8 and 8.1 months, respectively. Survival in the recanalization-positive and negative-groups was significantly different (p<0.05) after irradiation, with median survival times of 13.5 and 6.0 months, respectively. Complications of therapy were recognized in 68% of all cases. They were mainly gastrointestinal symptoms such as nausea, vomiting, erosive gastritis and loss of appetite, but they were not severe. Distant metastasis was recognized in only 4 patients (10%): three had bony metastasis and one had supraclavicular and pulmonary hilar lymph node metastasis. Ninety percent of all cases died from hepatic failure or peritonitis carcinomatosa due to failure to obtain local control by external irradiation. A more effective modality of treatment is necessary to cure these patients. (author).

    BACKGROUND: Endometrial cancer is mainly dependent on oestrogen exposure. Preeclampsia has shown to reduce oestrogen levels hence preeclampsia may affect later endometrial cancer risk. METHODS: We conducted a case-control study of 523 Danish women with endometrial cancer and 52 299controls during...... 1978-2010. The association between preeclampsia and later endometrial cancer was evaluated overall and according to preeclampsia onset and type of endometrial cancer in conditional logistic regression models. RESULTS: We observed no overall association between preeclampsia and endometrial cancer risk...... (OR=1.11 (95% CI 0.68-1.81)). This was true for all endometrial cancer subtypes. In an analysis of preeclampsia onset, however, we report a markedly increased risk of endometrial cancer following early-onset preeclampsia (OR=2.64 (95% CI 1.29-5.38)). CONCLUSIONS: Although we report no obvious...

    To investigate the effect and mechanism of mifepristone on the migration of human endometrial carcinoma cells. A human endometrial carcinoma cell line, Ishikawa cells, was cultured in vitro and treated with mifepristone at different concentrations. Wound healing assay was applied to detect the migration of Ishikawa cells. RT-PCR and methylation-specific PCR (MSP) were used to detect the levels of H19 mRNA and its DNA methylation. Western-blot was used to detect the expressions of HMGA2 and epithelial to mesenchymal transition (EMT) related proteins. When treated with different concentrations of mifepristone for 48 hours, the width of scratch of the the control group, the 5 mg/L and the 10 mg/L mifepristone treatment groups were (4.18±0.07)mm, (4.68±0.07)mm, and(4.99±0.07)mm, respectively (Pendometrial carcinoma cells partially through methylation-induced of transcriptional inhibition of H19, which results in the down-regulation of HMGA2 and vimentin and upregulation of E-cadherin.

    Purpose: To evaluate the long-term health-related quality of life (HRQL) after external beam radiation therapy (EBRT) or vaginal brachytherapy (VBT) among PORTEC-2 trial patients, evaluate long-term bowel and bladder symptoms, and assess the impact of cancer on these endometrial cancer (EC) survivors. Patients and Methods: In the PORTEC-2 trial, 427 patients with stage I high–intermediate-risk EC were randomly allocated to EBRT or VBT. The 7- and 10-year HRQL questionnaires consisted of EORTC QLQ-C30; subscales for bowel and bladder symptoms; the Impact of Cancer Questionnaire; and 14 questions on comorbidities, walking aids, and incontinence pads. Analysis was done using linear mixed models for subscales and (ordinal) logistic regression with random effects for single items. A two-sided P value <.01 was considered statistically significant. Results: Longitudinal HRQL analysis showed persisting higher rates of bowel symptoms with EBRT, without significant differences in global health or any of the functioning scales. At 7 years, clinically relevant fecal leakage was reported by 10.6% in the EBRT group, versus 1.8% for VBT (P=.03), diarrhea by 8.4% versus 0.9% (P=.04), limitations due to bowel symptoms by 10.5% versus 1.8% (P=.001), and bowel urgency by 23.3% versus 6.6% (P<.001). Urinary urgency was reported by 39.3% of EBRT patients, 25.5% for VBT, P=.05. No difference in sexual activity was seen between treatment arms. Long-term impact of cancer scores was higher among the patients who had an EC recurrence or second cancer. Conclusions: More than 7 years after treatment, EBRT patients reported more bowel symptoms with impact on daily activities, and a trend for more urinary symptoms, without impact on overall quality of life or difference in cancer survivorship issues.

    avaliar os fatores que poderão futuramente influenciar na indicação do procedimento em casos selecionados.PURPOSE: To evaluate the clinical outcomes after a minimum period of 5 years of follow-up of patients with abnormal uterine bleeding of benign etiology who underwent endometrial ablation, analyzing the success rate of treatment defined as patient satisfaction and improvement in uterine abnormal bleeding, as well as late complications and factors associated with recurrence of symptoms. METHODS: A cross-sectional survey was conducted after a minimum period of 5 years after surgery in patients who underwent the procedure between 1999 and 2004. We analyzed the following data: age at the time of surgery, immediate and late complications and associated factors. Logistic regression with Odds Ratio (OR calculation was performed to evaluate possible associations between the success rate of surgery and the analyzed variables. RESULTS: A total of 114 patients underwent endometrial ablation between March 1999 and April 2004. The median follow-up was 82 months. The logistic regression model allowed the correct prediction of the success of endometrial ablation in 80.6% of cases. Age was directly related to the success of the procedure (OR=1.2; p=0.003 and previous tubal ligation showed a negative association with the success of endometrial ablation (OR=0.3; p=0.049. Among the patients with treatment failure, 21 (72.4% underwent hysterectomy. In one of the hysterectomy cases, hydro/hematosalpinx was confirmed by the anatomopathological exam, characterizing the postablation-tubal sterilization syndrome. CONCLUSION: Endometrial ablation has proven to be a worthwhile treatment option, maintaining high rates of patient satisfaction, even over long-term follow-up. The age at endometrial ablation influenced the therapeutic success. Further studies are needed to evaluate the factors that may influence the future indication for the procedure in selected cases.

    Full Text Available Purpose. The purpose of this study was to analyze the expression of zinc-finger E-box-binding homeobox 1 (ZEB1 in endometrial biopsy and its correlation with preoperative characteristics, including lymph node metastases in patient with endometrial cancer. Methods. Using quantitative RT-PCR, ZEB1 expressions in endometrial biopsy from 452 patients were measured. The relationship between ZEB1 expression and preoperative characteristics was analyzed. Results. ZEB1 expressions were significantly associated with subtype, grade, myometrial invasion, and lymph node metastases. Lymph node metastases could be identified with a sensitivity of 57.8% at specificity of 74.1% by ZEB1 expression in endometrial biopsy. Based on combination of preoperative characteristics and ZEB1 expression, lymph node metastases could be identified with a sensitivity of 62.1% at specificity of 96.2% prior to hysterectomy. Conclusion. ZEB1 expression in endometrial biopsy could help physicians to better predict the lymph node metastasis in patients with endometrial cancer prior to hysterectomy.

    Purpose To determine the efficacy and complications of adjuvant vaginal high-dose-rate brachytherapy alone for patients with Stage I endometrial cancer in whom complete surgical staging had been performed. Methods and Materials Between April 1998 and March 2004, 100 patients with Stage I endometrial cancer underwent surgical staging (total abdominal hysterectomy and bilateral salpingo-oophorectomy with pelvic ± paraaortic nodal sampling) and postoperative vaginal high-dose-rate brachytherapy at our institution. The total dose was 2100 cGy in three fractions. Results With a median follow-up of 23 months (range 2-62), no pelvic or vaginal recurrences developed. All patients underwent pelvic dissection, and 42% underwent paraaortic nodal dissection. A median of 29.5 pelvic nodes (range 1-67) was removed (84% had >10 pelvic nodes removed). Most patients (73%) had endometrioid (or unspecified) adenocarcinoma, 16% had papillary serous carcinoma, and 11% had other histologic types. The International Federation of Gynecology and Obstetrics stage and grade was Stage IA, grade III in 5; Stage IB, grade I, II, or III in 6, 27, or 20, respectively; and Stage IC, grade I, II, or III in 13, 17, or 10, respectively. The Common Toxicity Criteria (version 2.0) complications were mild (Grade 1-2) and consisted primarily of vaginal mucosal changes, temporary urinary irritation, and temporary diarrhea. Conclusion Adjuvant vaginal high-dose-rate brachytherapy alone may be a safe and effective alternative to pelvic external beam radiotherapy for surgical Stage I endometrial cancer

    Background Understanding the molecular basis of embryonic implantation is of great clinical and biological relevance. Little is currently known about the adhesion receptors that determine endometrial receptivity for embryonic implantation in humans. Methods and Principal Findings Using two human endometrial cell lines characterized by low and high receptivity, we identified the membrane receptor CD98 as a novel molecule selectively and significantly associated with the receptive phenotype. In human endometrial samples, CD98 was the only molecule studied whose expression was restricted to the implantation window in human endometrial tissue. CD98 expression was restricted to the apical surface and included in tetraspanin-enriched microdomains of primary endometrial epithelial cells, as demonstrated by the biochemical association between CD98 and tetraspanin CD9. CD98 expression was induced in vitro by treatment of primary endometrial epithelial cells with human chorionic gonadotropin, 17-β-estradiol, LIF or EGF. Endometrial overexpression of CD98 or tetraspanin CD9 greatly enhanced mouse blastocyst adhesion, while their siRNA-mediated depletion reduced the blastocyst adhesion rate. Conclusions These results indicate that CD98, a component of tetraspanin-enriched microdomains, appears to be an important determinant of human endometrial receptivity during the implantation window.

    Laparoscopic hysterectomy (LH) is increasingly used for the management of endometrial malignancy. Its benefits may be particularly pronounced as these women are more likely to be older or obese. The aim of this study was to determine whether outcomes for LH are comparable to the open hysterectomy (OH). This was a prospective cohort study nested within the multicenter ASTEC (A Study in the Treatment of Endometrial Cancer) randomized controlled trial (1998-2005). Women with presumed early endometrial cancer were included. Laparoscopic hysterectomy was compared with OH with or without systematic lymphadenectomy. Overall survival, time to first recurrence, complication rates, and surgical outcomes were the main outcome measures. Of 1408 women, 1309 (93%) received OH, and 99 (7%) had LH. LH was associated with longer operating time (median, LH 105 minutes [interquartile range (IQR), 60-150] vs OH 80 minutes [IQR, 60-95]; P < 0.001) but 50% shorter hospital stay (median, LH 4 days [IQR, 3-5] vs OH 6 days [IQR, 5-7]). The number of harvested lymph nodes was similar (median, LH 13 [IQR, 10-16] vs OH 12 [IQR, 11-13]; P = 0.67). LH had fewer intraoperative and postoperative adverse events (9% difference, LH 21% vs OH 30%; borderline significance; P = 0.07). The rate of conversion to laparotomy for the LH group was high (27%). The median follow-up was 37 months. After adjusting for significant prognostic factors, the hazard ratio for overall survival in those who underwent LH compared with those who underwent OH was 0.67 (95% confidence interval, 0.31-1.43) (P = 0.30). Laparoscopic hysterectomy for early endometrial cancer is safe. Although it requires longer operating time it is associated with shorter hospital stay and favorable morbidity profile. Further studies are required to assess the long-term safety.

    To assess and compare efficacy, pain, and the learning curve associated with diagnostic therapeutic hysteroscopy using mechanical tissue removal versus bipolar electrical resection in the management of endometrial polyps in an ambulatory care setting. A randomized controlled clinical trial (Canadian Task Force classification I). Hospital de Igulada, Barcelona, Spain. A total of 133 patients diagnosed with endometrial polyp(s) were included and randomly assigned to 1 of the 2 hysteroscopic methods. Criteria assessed were total hysteroscopy time, full polypectomy procedure time, pain experienced by patients, and learning curve of staff in training. The average time to perform total hysteroscopy using the mechanical tissue removal system (TRUCLEAR 5.0 System; Smith & Nephew Inc., Andover, MD) was 6 minutes 49 seconds versus 11 minutes 37 seconds required for the bipolar electrosurgery system (GYNECARE VERSAPOINT; Ethicon Inc, Somerville, NJ) (p .05). A study of the residents' learning curve showed a higher level of autonomy with hysteroscopy using the TRUCLEAR Tissue Removal System with which residents showed a higher level of confidence compared with hysteroscopy with the VERSAPOINT Bipolar Electrosurgery System. In hysteroscopic polypectomy, the mechanical tissue removal system was significantly faster, achieved a greater success rate for complete polypectomy, and required a shorter learning curve from staff being trained in the management of endometrial polyps when compared with bipolar electrical resection.

    Small intestinal volvulus is a rare complication following Roux-en-Y anastomosis. A 63-year-old woman was diagnosed with small intestinal volvulus following laparotomy for clear cell carcinoma of the endometrium. Her past medical history included a total gastrectomy and antecolic Roux-en-Y anastomosis for Duke's B gastric carcinoma. Operative findings were of transmesenteric herniation of the ileum through the Roux-en-Y small intestinal mesenteric window, with metastatic deposits fixing the hernia at its base to create a volvulus. The proximal transverse colon was very dilated and thin due to partial obstruction by the volvulus. Her treatment involved adhesiolysis and unraveling of the small intestinal volvulus. This is the first case report of a small intestinal volvulus following a Roux-en-Y anastomosis involving a metastatic gynacological malignancy.

    Full Text Available Because epigenetic alterations are believed to be involved in the repression of tumor suppressor genes and promotion of tumorigenesis in endometrial cancers, novel compounds endowed with a histone deacetylase (HDAC inhibitory activity are an attractive therapeutic approach. In this review, we discuss the biologic and therapeutic effects of HDAC inhibitors (HDACIs in treating endometrial cancer. HDACIs were able to mediate inhibition of cell growth, cell cycle arrest, apoptosis, and the expression of genes related to the malignant phenotype in a variety of endometrial cancer cell lines. Furthermore, HDACIs were able to induce the accumulation of acetylated histones in the chromatin of the p21WAF1 gene in human endometrial carcinoma cells. In xenograft models, some HDACIs have demonstrated antitumor activity with only few side effects. In this review, we discuss the biologic and therapeutic effects of HDACIs in treating endometrial cancer, with a special focus on preclinical studies.

    Purpose: To evaluate the survival benefit of adding vaginal brachytherapy (BT) to pelvic external beam radiation therapy (EBRT) in women with stage III endometrial cancer. Methods and Materials: The National Cancer Data Base was used to identify patients with stage III endometrial cancer from 2004 to 2013. Only women who received adjuvant EBRT were analyzed. Women were grouped according to receipt of BT. Logistic regression modeling was used to identify predictors of receiving BT. Log–rank statistics were used to compare survival outcomes. Cox proportional hazards modeling was used to evaluate the effect of BT on survival. A propensity score–matched analysis was also conducted among women with cervical involvement. Results: We evaluated 12,988 patients with stage III endometrial carcinoma, 39% of whom received EBRT plus BT. Women who received BT were more likely to have endocervical or cervical stromal involvement (odds ratios 2.03 and 1.77; P<.01, respectively). For patients receiving EBRT alone, the 5-year survival was 66% versus 69% with the addition of BT at 5 years (P<.01). Brachytherapy remained significantly predictive of decreased risk of death (hazard ratio 0.86; P<.01) on multivariate Cox regression. The addition of BT to EBRT did not affect survival among women without cervical involvement (P=.84). For women with endocervical or cervical stromal invasion, the addition of BT significantly improved survival (log–rank P<.01). Receipt of EBRT plus BT was associated with improved survival in women with positive and negative surgical margins, and receiving chemotherapy did not alter the benefit of BT. Propensity score–matched analysis results confirmed the benefit of BT among women with cervical involvement (hazard ratio 0.80; P=.01). Conclusions: In this population of women with stage III endometrial cancer the addition of BT to EBRT was associated with an improvement in survival for women with endocervical or cervical stromal invasion.

Cox proportional hazards modeling was used to evaluate the effect of BT on survival. A propensity score–matched analysis was also conducted among women with cervical involvement. Results: We evaluated 12,988 patients with stage III endometrial carcinoma, 39% of whom received EBRT plus BT. Women who received BT were more likely to have endocervical or cervical stromal involvement (odds ratios 2.03 and 1.77; P<.01, respectively). For patients receiving EBRT alone, the 5-year survival was 66% versus 69% with the addition of BT at 5 years (P<.01). Brachytherapy remained significantly predictive of decreased risk of death (hazard ratio 0.86; P<.01) on multivariate Cox regression. The addition of BT to EBRT did not affect survival among women without cervical involvement (P=.84). For women with endocervical or cervical stromal invasion, the addition of BT significantly improved survival (log–rank P<.01). Receipt of EBRT plus BT was associated with improved survival in women with positive and negative surgical margins, and receiving chemotherapy did not alter the benefit of BT. Propensity score–matched analysis results confirmed the benefit of BT among women with cervical involvement (hazard ratio 0.80; P=.01). Conclusions: In this population of women with stage III endometrial cancer the addition of BT to EBRT was associated with an improvement in survival for women with endocervical or cervical stromal invasion.

    Postmenopausal bleeding (PMB) can be the first sign of endometrial cancer. In case of thickened endometrium, endometrial sampling is often used in these women. In this systematic review, we studied the accuracy of endometrial sampling for the diagnoses of endometrial cancer, atypical hyperplasia and endometrial disease (endometrial pathology, including benign polyps). We systematically searched the literature for studies comparing the results of endometrial sampling in women with postmenopausal bleeding with two different reference standards: blind dilatation and curettage (D&C) and hysteroscopy with histology. We assessed the quality of the detected studies by the QUADAS-2 tool. For each included study, we calculated the fraction of women in whom endometrial sampling failed. Furthermore, we extracted numbers of cases of endometrial cancer, atypical hyperplasia and endometrial disease that were identified or missed by endometrial sampling. We detected 12 studies reporting on 1029 women with postmenopausal bleeding: five studies with dilatation and curettage (D&C) and seven studies with hysteroscopy as a reference test. The weighted sensitivity of endometrial sampling with D&C as a reference for the diagnosis of endometrial cancer was 100% (range 100-100%) and 92% (71-100) for the diagnosis of atypical hyperplasia. Only one study reported sensitivity for endometrial disease, which was 76%. When hysteroscopy was used as a reference, weighted sensitivities of endometrial sampling were 90% (range 50-100), 82% (range 56-94) and 39% (21-69) for the diagnosis of endometrial cancer, atypical hyperplasia and endometrial disease, respectively. For all diagnosis studied and the reference test used, specificity was 98-100%. The weighted failure rate of endometrial sampling was 11% (range 1-53%), while insufficient samples were found in 31% (range 7-76%). In these women with insufficient or failed samples, an endometrial (pre) cancer was found in 7% (range 0-18%). In women with

    Objective: In this study, the authors discussed the feasibility and value of diffusion-weighted (DW) MR imaging in the detection of uterine endometrial cancer in addition to conventional nonenhanced MR images. Methods and materials: DW images of endometrial cancer in 23 patients were examined by using a 1.5-T MR scanner. This study investigated whether or not DW images offer additional incremental value to conventional nonenhanced MR imaging in comparison with histopathological results. Moreover, the apparent diffusion coefficient (ADC) values were measured in the regions of interest within the endometrial cancer and compared with those of normal endometrium and myometrium in 31 volunteers, leiomyoma in 14 patients and adenomyosis in 10 patients. The Wilcoxon rank sum test was used, with a p < 0.05 considered statistically significant. Results: In 19 of 23 patients, endometrial cancers were detected only on T2-weighted images. In the remaining 4 patients, of whom two had coexisting leiomyoma, no cancer was detected on T2-weighted images. This corresponds to an 83% detection sensitivity for the carcinomas. When DW images and fused DW images/T2-weighted images were used in addition to the T2-weighted images, cancers were identified in 3 of the remaining 4 patients in addition to the 19 patients (overall detection sensitivity of 96%). The mean ADC value of endometrial cancer (n = 22) was (0.97 {+-} 0.19) x 10{sup -3} mm{sup 2}/s, which was significantly lower than those of the normal endometrium, myometrium, leiomyoma and adenomyosis (p < 0.05). Conclusion: DW imaging can be helpful in the detection of uterine endometrial cancer in nonenhanced MR imaging.

    From 1973 to 1977, 20 patients who had histologically proven unresectable adenocarcinoma of the pancreas with no distant metastases were irradiated at the Medical College of Wisconsin Affiliated Hospitals. The patients received megavoltage external irradiation to minimum tumor doses ranging between 3000 rad in 4 weeks and 5700 rad in 7 weeks (median 4600 rad in 6 weeks); their actuarial survival was 54% at 12 months and 21% at 24 months. Fourteen patients who received 4500 rad or more in 6 to 7 weeks had a median survival of 13 months. Six patients received less than 4500 rad in 3 to 6 weeks, and their median survival was 7 months. At this writing, three patients are alive and apparently disease free more than 2 years after treatment. Complications were seen in two patients. One died from GI bleeding 2 months after completion of radiation therapy, and the other patient developed pancreatic insufficiency. These results and recent reports in the literature show that aggressive irradiation can result in long-term disease free survival in a small proportion of patients with unresectable pancreatic adenocarcinoma. Further exploitation of this approach alone or combined with chemotherapy is warranted

    Uterine factors influence reproduction at the macro-anatomy level, and the effects of hormonal steroids on endometrial morphology are well recognized in the histopathological diagnosis of dysfunctional bleeding and infertility. During the past decade, attention has been paid to endometrial protein synthesis and secretion with respect to endocrine stimuli and implantation, and to the paracrine/autocrine effects of endometrial peptide growth factors, their binding proteins and other factors. The emphasis of this presentation is on protein secretion of the secretory endometrium, in which progesterone plays a pivotal role. Insulin-like growth factors have receptors on the endometrium, and IGF-binding proteins, stimulated by progesterone, modulate the effects of IGFs locally. Also other protein products of the secretory endometrium have been reviewed in this communication, with special emphasis on studies of a progesterone-associated endometrial protein which has many names in the literature, such as PEP, PP14, alpha 2-PEG and AUP. Extensive studies are ongoing in many laboratories to elucidate the regulation, function, interplay at tissue and cellular levels, and clinical significance of these proteins.

    Grading and histologic typing of endometrial cancer in biopsy material has a direct impact on the decision to perform lymphadenectomy and/or omentectomy in many cancer centers. Endometrial biopsies are among the most common general surgical pathology specimens. Multiple studies have shown...... that biopsy diagnosis suffers from a lack of reproducibility. Although many biomarkers have been proposed, none have been demonstrated to improve the diagnosis in the biopsy setting.

    Full Text Available The most important prognostic factors for clear cell carcinoma (CCC are clinical and morphological signs and clinical stage of the disease. Analyses of 5-year survival in patients with I stage of CCC is 69 %, in II stage – 55 %, in III stage – 14 % and in IV stage – 4 % patients. We analyzed distant results of treatment of 71 patients with CCC and of 25 patients with mixed malignant ovaries neoplasm with obligatory clear cell component taking into consideration main clinical and morphological sings of disease. On the base of performed reseal we revealed that morphological structure of the tumors and stage of the disease exerted heist influence on the exponent of survival of the patients with clear CCC ovaries neoplasm. Besides, there is a correlation between exponent of patients’ survival and radicalized of surgery, character of tumor growth, differentiation degree, cell anaplasia and mitotic activity of tumor cells.

    The renal cell cancer incidence is relatively low in younger patients, encompassing 3% to 7% of all renal cell cancers. While young patients may have renal tumors due to hereditary syndromes, in some of them sporadic renal cancers develop without any family history or known genetic mutations. Our recent observations from clinical practice have led us to hypothesize that there is a difference in histological distribution in younger patients compared to the older cohort. We queried the SEER (Surveillance, Epidemiology and End Results) 18-registry database for all patients 20 years old or older who were surgically treated for renal cell carcinoma between 2001 and 2008. Patients with unknown race, grade, stage or histology and those with multiple tumors were excluded from study. Four cohorts were created by dividing patients by gender, including 1,202 females and 1,715 males younger than 40 years old, and 18,353 females and 30,891 males 40 years old or older. Chi-square analysis was used to compare histological distributions between the cohorts. While clear cell carcinoma was still the most common renal cell cancer subtype across all genders and ages, chromophobe renal cell cancer was the most predominant type of nonclear renal cell cancer histology in young females, representing 62.3% of all nonclear cell renal cell cancers (p renal cell cancer remained the most common type of nonclear renal cell cancer. It is possible that hormonal factors or specific pathway dysregulations predispose chromophobe renal cell cancer to develop in younger women. We hope that this work provides some new observations that could lead to further studies of gender and histology specific renal tumorigenesis.

    Stroma-tumor communication participates in the pathogenesis of endometrial carcinomas. In previous studies, we found that normal stromal cells inhibited the growth of endometrial carcinoma cells. Here, we investigated the role of normal stromal cells in the epithelial-mesenchymal transition (EMT) of endometrial carcinoma cells and explored the possible mechanism implied. We found that conditioned medium (CM) by normal endometrial stromal cells (NSC) reduced cell growth and induced cell apoptosis in Ishikawa cells. CM by NSC inhibited 17β-estradiol-induced cell growth and apoptosis decrease in Ishikawa cells. Moreover, CM by NSC inhibited the migration and invasion, and 17β-estradiol-induced migration and invasion in Ishikawa cells. Meanwhile, CM by NSC decreased Slug expression and 17β-estradiol-induced Slug expression, increased E-cadherin expression and abolished 17β-estradiol-induced E-cadherin reduction in Ishikawa cells. In conclusion, normal stromal factors can inhibit 17β-estradiol-induced cell proliferation and apoptosis inhibition, and abolished 17β-estradiol-induced EMT in endometrial cancer cell via regulating E-cadherin and Slug expression.

  11. Benign endometrial proliferations mimicking malignancies: a review of problematic entities in small biopsy specimens.

    Ip, Philip Pun-Ching

    Benign proliferations that mimic malignancies are commonly encountered during the course of assessment of small and fragmented endometrial samples. Although benign, endometrial epithelial metaplasias often coexist with premalignant or malignant lesions causing diagnostic confusion. The difficulty with mucinous metaplasia lies in its distinction from atypical mucinous glandular proliferations and mucinous carcinomas, which are associated with significant interobserver variability. Papillary proliferation of the endometrium is commonly associated with hormonal drugs and endometrial polyps and is characterised by papillae with fibrovascular cores covered by epithelial cells without cytologic atypia. They are classified into simple or complex papillary proliferations depending on the architectural complexity and extent of proliferation. Complex papillary proliferations are associated with a high risk of concurrent or subsequent hyperplasia with atypia/carcinoma. Papillary proliferations may have coexisting epithelial metaplasias and, most commonly, mucinous metaplasia and syncytial papillary change. Those with striking mucinous metaplasia overlap morphologically with papillary mucinous metaplasia. The latter has been proposed as a precursor of endometrial mucinous carcinoma. Misinterpreting the Arias-Stella reaction as a malignant or premalignant lesion is more likely to occur if the pathologist is unaware that the patient is pregnant or on hormonal drugs. Endometrial hyperplasia with secretory changes may occasionally be difficult to distinguish from the torturous and crowded glands of a late secretory endometrium. Endometrial polyps may have abnormal features that can be misinterpreted as endometrial hyperplasia or Mullerian adenosarcoma. Awareness of these benign endometrial proliferations and their common association with hormonal medication or altered endogenous hormonal levels will help prevent the over-diagnosis of premalignant and malignant lesions.

    Early endometrial cancer with low-risk pathological features can be successfully treated by surgery alone. External beam radiotherapy added to surgery has been investigated in several small trials, which have mainly included women at intermediate risk of recurrence. In these trials, postoperative radiotherapy has been shown to reduce the risk of isolated local recurrence but there is no evidence that it improves recurrence-free or overall survival. We report the findings from the ASTEC and EN.5 trials, which investigated adjuvant external beam radiotherapy in women with early-stage disease and pathological features suggestive of intermediate or high risk of recurrence and death from endometrial cancer. Between July, 1996, and March, 2005, 905 (789 ASTEC, 116 EN.5) women with intermediate-risk or high-risk early-stage disease from 112 centres in seven countries (UK, Canada, Poland, Norway, New Zealand, Australia, USA) were randomly assigned after surgery to observation (453) or to external beam radiotherapy (452). A target dose of 40-46 Gy in 20-25 daily fractions to the pelvis, treating five times a week, was specified. Primary outcome measure was overall survival, and all analyses were by intention to treat. These trials were registered ISRCTN 16571884 (ASTEC) and NCT 00002807 (EN.5). After a median follow-up of 58 months, 135 women (68 observation, 67 external beam radiotherapy) had died. There was no evidence that overall survival with external beam radiotherapy was better than observation, hazard ratio 1.05 (95% CI 0.75-1.48; p=0.77). 5-year overall survival was 84% in both groups. Combining data from ASTEC and EN.5 in a meta-analysis of trials confirmed that there was no benefit in terms of overall survival (hazard ratio 1.04; 95% CI 0.84-1.29) and can reliably exclude an absolute benefit of external beam radiotherapy at 5 years of more than 3%. With brachytherapy used in 53% of women in ASTEC/EN.5, the local recurrence rate in the observation group at 5 years

    To evaluate the biological outcomes of plasma rich in growth factors (PRGF) on human endometrial fibroblasts in culture. PRGF was obtained from three healthy donors and human endometrial fibroblasts (HEF) were isolated from endometrial specimens from five healthy women. The effects of PRGF on cell proliferation and migration, secretion of vascular endothelial growth factor (VEGF), procollagen type I and hyaluronic acid (HA) and contractility of isolated and cultured human endometrial fibroblasts (HEF) were analyzed. Statistical analysis was performed in order to compare the effects of PRGF with respect to control situation (T-test or Mann-Whitney U-test). We report a significantly elevated human endometrial fibroblast proliferation and migration after treatment with PRGF. In addition, stimulation of HEF with PRGF induced an increased expression of the angiogenic factor VEGF and favored the endometrial matrix remodeling by the secretion of procollagen type I and HA and endometrial regeneration by elevating the contractility of HEF. These results were obtained for all PRGF donors and each endometrial cell line. The myriad of growth factors contained in PRGF promoted HEF proliferation, migration and synthesis of paracrine molecules apart from increasing their contractility potential. These preliminary results suggest that PRGF improves the biological activity of HEF in vitro, enhancing the regulation of several cellular processes implied in endometrial regeneration. This innovative treatment deserves further investigation for its potential in "in vivo" endometrial development and especially in human embryo implantation. Copyright © 2016 Elsevier Ireland Ltd.

    We analyzed the results of radiotherapy in 36 patients with hypopharyngeal carcinoma. The overall 2-year and 5-year survival rates were 45.3% and 31.1%, respectively. For 23 patients given radical irradiation, the corresponding figures were 37.8% and 28.3%. However, in 16 patients receiving a combined therapy of radical irradiation and chemotherapy, mainly an intraarterial injection of cisplatin, the survivals were better; the 2-year survival rate was 50.0% and four patients have survived for more than three years without recurrence. In managing patients with hypopharyngeal carcinoma, this combined therapy would improve therapeutic outcome and also assist in larynx preservation. (J.P.N.)

    The use of third-line targeted therapy (TTT) in metastatic renal cell carcinoma (mRCC) is not well characterized and varies due to the lack of robust data to guide treatment decisions. This study examined the use of third-line therapy in a large international population. To evaluate the use and efficacy of targeted therapy in a third-line setting. Twenty-five international cancer centers provided consecutive data on 4824 mRCC patients who were treated with an approved targeted therapy. One thousand and twelve patients (21%) received TTT and were included in the analysis. Patients were analyzed for overall survival (OS) and progression-free survival using Kaplan-Meier curves, and were evaluated for overall response. Cox regression analyses were used to determine the statistical association between OS and the six factors included in the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC) prognostic model. Subgroup analysis was performed on patients stratified by their IMDC prognostic risk status. Everolimus was the most prevalent third-line therapy (27.5%), but sunitinib, sorafenib, pazopanib, temsirolimus, and axitinib were all utilized in over ≥9% of patients. Patients receiving any TTT had an OS of 12.4 mo, a progression-free survival of 3.9 mo, and 61.1% of patients experienced an overall response of stable disease or better. Patients not receiving TTT had an OS of 2.1 mo. Patients with favorable- (7.2%) or intermediate-risk (65.3%) disease had the highest OS with TTT, 29.9 mo and 15.5 mo, respectively, while poor-risk (27.5%) patients survived 5.5 mo. Results are limited by the retrospective nature of the study. TTT remains highly heterogeneous. The IMDC prognostic criteria can be used to stratify third-line patients. TTT use in favorable- and intermediate-risk patients was associated with the greatest OS. Patients with favorable- and intermediate-prognostic criteria disease treated with third-line targeted therapy have an associated

    The principle of the therapy of carcinoma cervicis uteri in the Research Institute of Clinical and Experimental Oncology in Brno is the combination of betatron megavoltage irradiation and cobalt 60 irradiation with intracavital radium irradiation. On the basis of many years' study concerning the therapy and therapeutic results of this tumor accurate directions of total therapy were elaborated. Carcinoma is diagnosed and classified precisely according to valid international directions. In addition to basic examination, limb lymphography was introduced giving the strategy of irradiation when lymphatic system is involved and in early stages of the disease. By preliminary evaluation of the obtained data a certain improvement of therapeutic results is proven. About 15% more patients are alive till 5 years without any signs of the disease than in precedent years. In spite of a high dose summation given by the extent of megavoltage irradiation the number of postirradiation reaction, nor early late, is increased to much. Complex therapy of this tumor is performed by a team of physicians composed of gynecologist, radiologist, rentgendiagnosticist, pathologist, and radiation physicist. By increasing the number of cured patients and their return and enclosure into further working process the savings in state budget are achieved. The effectiveness of the carcinoma cervicis uteri therapy is therefore dependent not only on earlier diagnosis and modern irradiation technique, but also on the cooperation of a team of physicians who plan, perform and follow the therapy.

    Ultrasound offers essential details and an overall view of the anatomic features of the reproductive organs, as well as physiologic assessment. There is still a great gap, however, in our understanding and interpretation of endometrial sonographic findings. Endometrial thickness, growth, and sonographic patterns have been repeatedly tested and compared with pregnancy rates in IVF cycles, yielding conflicting results. Generally, the data accrued so far suggest refraining from clinical decisions based solely on endometrial thickness. The three-layer ultrasound pattern reflects normal follicular/proliferative dynamics, and its presence in the pre-hCG period was reported to carry a better outcome: Significantly higher clinical pregnancy rates were found in patients with this pattern on the day of hCG administration among IVF cohorts. Subendometrial contractility (endometrial "waves") offers a tool that can be used in cases of repeated implantation failure in patients reporting cramps around the planned time of embryo transfer, or as a reassuring modality to assess uterine quiescence during preparations for embryo transfer. We support the creation of an integrated endometrial score incorporating conservative endometrial measurements, endometrial-myometrial junction studies, and endometrial contractility, as well as new concepts that remain to be tested, such as endometrial surface area. Such scores may enable us to improve the effectiveness of endometrial ultrasound imaging in the clinical setting. Copyright © 2016 American Society for Reproductive Medicine.

    New reliable approaches to stratify patients with endometrial cancer into risk categories are highly needed. We have recently demonstrated that DJ-1 is overexpressed in endometrial cancer, showing significantly higher levels both in serum and tissue of patients with high-risk endometrial cancer compared with low-risk endometrial cancer. In this experimental study, we further extended our observation, evaluating the role of DJ-1 as an accurate serum biomarker for high-risk endometrial cancer. A total of 101 endometrial cancer patients and 44 healthy subjects were prospectively recruited. DJ-1 serum levels were evaluated comparing cases and controls and, among endometrial cancer patients, between high- and low-risk patients. The results demonstrate that DJ-1 levels are significantly higher in cases versus controls and in high- versus low-risk patients. The receiver operating characteristic curve analysis shows that DJ-1 has a very good diagnostic accuracy in discriminating endometrial cancer patients versus controls and an excellent accuracy in distinguishing, among endometrial cancer patients, low- from high-risk cases. DJ-1 sensitivity and specificity are the highest when high- and low-risk patients are compared, reaching the value of 95% and 99%, respectively. Moreover, DJ-1 serum levels seem to be correlated with worsening of the endometrial cancer grade and histotype, making it a reliable tool in the preoperative decision-making process.

    A 35 year old woman with endometrial cancer and cervical extension underwent F18 FDG PET CT and MRI studies after resection of a cervical mass presumed to be cervical myoma. The patient underwent cervical myomectomy and the histopathologic report revealed poorly differentiated invasive carcinoma. Cervical cancer was ruled out because the patient had no history of sexual intercourse and was negative for human papilloma virus infection. The patient underwent radical hysterectomy, bilateral salpingo oophorectomy, pelvic and para aortic lymph node dissection, and multiple biopsies. F18 FDG PET CT showed intense FDG uptake along the cervix wall. T2 weighted MRI also revealed a mass lesion with high SI involving the anterior and posterior lips of the uterine cervix. Another area of focal increased uptake above the endometrial lesion in the left pelvic cavity was observed on PET CT and MRI, possibly due to a functioning ovary. PET CT and MRI were interpreted as showing a dual concordant malignant lesion due to separated FDG uptakes and high SI without any connection between the cervical and endometrial lesions. F18 FDG PET CT showed intense FDG uptake along the endometrium. Given the patient's history and the fact that she was not menstruating at the time of imaging, this intense uptake was interpreted as another pathologic lesion, suggesting dual primary lesions. A suspected heterogeneous mass lesion along the endometrium suggesting concordant endometrial cancer was found on MRI. Endometrial cancer with cervical extension is sometimes difficult to differentiate from primary cervical cancer. The final histopathologic report showed poorly differentiated endometrial adenocarcinoma with cervical extension, although the FDG PET CT and MRI findings were suggestive of concordant cervical and endometrial cancer. Although histopathologic confirmation is necessary for final diagnosis, MRI and FDG PET CT studies may aid in the differential diagnosis. A metastatic cervical mass from

    Full Text Available Patients diagnosed with an endometrial cancer precursor lesion on biopsy may be found to have endometrial cancer at the time of subsequent surgery. The current study seeks to identify patients with endometrial intraepithelial neoplasia (EIN on biopsy that may be harboring an occult carcinoma. Immunohistochemical stains for gene loss of expression (LOE for 6 genes, PTEN, ARID1A, MSH6, MSH2, MLH1, and PMS2, were performed on 113 biopsy specimens with EIN. For the 95 patients with follow-up histology, 40 patients had cancer, 41 had EIN, and 14 had normal endometrium. PTEN LOE was found frequently in both EIN and endometrial cancer, and therefore had low positive predictive value. All specimens with ARID1A, MSH6, MSH2, MLH1, or PMS2 LOE on biopsy were subsequently found to have cancer. LOE of any gene was associated with modest sensitivity (0.78 in identifying patients with endometrial cancer who had EIN on biopsy. Further investigation is warranted to determine if gene LOE is a useful clinical tool when evaluating patients with EIN on biopsy.

    Full Text Available Perimenopausal menopausal hemorrhage can be due to by a variety of causative factors. One of its dangerous causes is atypical hyperplasia and endometrial carcinoma. There are a number of risk factors for the occurrence of endometrial carcinoma. The group that has this risk belongs to high-risk group. In this high-risk group, it is necessary to have a method to identify the changes in endometrial abnormality. One of the alternatives is the examination of endometrial cytology. The objective of this study was to evaluate the sensitivity, specificity and correlation test between endometrial cytology and endometrial histology. This study was a diagnostic test of cytological examination of the endometrium as compared with endometrial histology. Endometrial cytology was performed with a modification of cytubrush and IUD shell. Specimen was dissolved into the centrifuged NaCl, and its deposits were then processed for cytological examination with Papanicolaou and Giemsa staining. After the taking of cytology, the process was continued with curettage of the endometrium, and the specimens were processed for cytological examination. Both of them were examined by anatomic pathologist. Statistical analysis used diagnostic test using histological examination of curetage specimens as gold standard. During the period of study 45 study samples were collected, among which 12 (26.66% were endometrial adenocarcinoma, 6 (13.33% with atypical hyperplasia, 11 (24.44% with non-atypical hyperplasia, 15 (33.33% were samples without abnormality, and one sample with endometritis. Actual correlation value was 57.8%, correlation because of possibility 3.38%, and correlation not because of possibility 54.42%, potential correlation not because of possibility 96.62%, and Kappa value 0.56. It was concluded that cytological examination of the endometriurn with cytobrush could be employed as a screening method in the abnormalities of endometrial thickness, with

    Full Text Available Endometrial intraepithelial neoplasia (EIN is a monoclonal neoplastic cell proliferation of the endometrium associated with a significantly increased risk of endometrioid endometrial adenocarcinoma. We herein present the case of a 58-year-old female patient who underwent a hysterectomy with bilateral salpingo-oophorectomy because of the existence of endometrial intraepithelial neoplasia in an endometrial polyp. The patient had irregular uterine bleeding, which lasted 10 days. An endometrial polyp was diagnosed by ultrasound examination. The polyp was located in the isthmus of the uterus, on the back wall, and measured 32 mm × 25 mm. The patient underwent fractional dilation and curettage, and the specimens were subjected to a histopathological examination. The histopathological findings were EIN, endometrioid type, a focus of which was found within the endometrial polyps, as well as the endometrial polyp and proliferative endometrium. The endocervical tissue was normal. Given the age of the patient and the histopathological findings, she underwent a total abdominal hysterectomy with bilateral salpingo-oophorectomy. The final histopathological findings were EIN, endometrioid type with a focus found within the endometrial polyp; endometrial polyp; simple hyperplasia; chronic inflammation of the uterine cervix; hyperkeratosis of the cervical squamous epithelium; and cervicitis chronica. There was also hydrosalpinx of the left fallopian tube, and cystic follicles in the left ovary. There was no significant morphological change in the right ovary or fallopian tube. The surgical and postoperative course were normal. The patient was sent home on the fifth postoperative day in good general condition. A check-up performed one month after surgery showed normal findings.

    Inflammation is a key process in the establishment and progression of endometriosis. Resistin, an adipocytokine, has biological properties linked to immunologic functions, but its role in endometriosis is unclear. Resistin gene expression was examined in eutopic and ectopic endometrial tissues from women with (n=25) or without (n=25) endometriosis. Resistin mRNA and protein levels were determined in endometrial tissue using quantitative real-time reverse transcription PCR and Western blotting, following adipokine profiling arrays. Resistin protein was detected in human endometrial tissues using an adipokine array test. Resistin mRNA and protein levels were significantly higher in ectopic endometrial tissue of patients with endometriosis than in normal eutopic endometrial tissue. Our results indicate that resistin is differentially expressed in endometrial tissues from women with endometriosis and imply a role for resistin in endometriosis-associated pelvic inflammation. © 2017 John Wiley & Sons A/S.

    The results of the treatment of 28 patients with an anaplastic thyroid gland carcinoma are investigated, to see whether an optimal therapy is indicated. The execution of an operation before radiotherapy does not appear to improve the prognosis (statistically this conclusion is not wholly justified). The presence of metastases at the beginning of the therapy gave rise to a worse prognosis than the absence of metastases. The combination treatment of chemotherapy and either surgery or radiotherapy was only applied to two patients so no conclusions can be made about its benefit. (C.F.)

    In the years 1962-1966 225 patients with carcinoma of the rubor labiorum were observed in the Institute of Oncology in Gliwice. The patients were treated surgically or with X-rays. In the group of 204 treated patients the 5-year survival rate was 86% without signs of recurrence (after taking into consideration the natural mortality in the population). Advanced cases were treated mostly with X-rays. Evaluation of nominal standard dose on tissues showed best results in the group in which this dose was about 1700 r.

    The effectiveness of elevated temperature (hyperthermia) in cancer treatment is a well-known issue. However, due to technical problems with generating hyperthermia within the tumour and, at the same time, sparing the healthy tissues, in practice this modality is not widely used. Local hyperthermia was induced by a computer-controlled generator (500 kHz) with three amplifiers transmitting energy to the lesion via a modified uterine brachytherapy applicator. Temperature was measured with 3 thermocouples.Total treatment time was 60-90 minutes. 10 patients with cervical and endometrial cancer were enrolled into this study and 11 procedures were performed. Prior to hyperthermia all patients were treated with external field irradiation to the pelvis to the dose of 45-46 Gy. Intracavitary LDR/HDR brachytherapy (dose of 45 Gy/point Ai n two fractions) with colpostat used for the hyperthermia procedure was than performed. In all cases, except one, caused by equipment failure, biologically stable temperature was observed. No severe side effects of treatment were observed. There was no need to terminate treatment due to high temperature intolerance. (author)

    Full Text Available Endometrial evaluation is generally indicated in cases presenting with abnormal uterine bleeding (AUB, especially in women more than 35 years of age. AUB encompasses a variety of presentation, for example, heavy menstrual bleeding, frequent bleeding, irregular vaginal bleeding, postcoital and postmenopausal bleeding to name a few. Many methods are used for the evaluation of such cases, with most common being sonography and endometrial biopsy with very few cases requiring more invasive approach like hysteroscopy. Endometrial aspiration is a simple and safe office procedure used for this purpose. Materials and Methods: We retrospectively analyzed cases of AUB where endometrial aspiration with Pipette (Medgyn was done in outpatient department between January 2015 and April 2016. Case records (both paper and electronic were used to retrieve data. Results: One hundred and fifteen cases were included in the study after applying inclusion and exclusion criteria. Most cases were between 46 and 50 years of age followed by 41–45 years. No cases were below 25 or more than 65 years of age. Heavy menstrual bleeding was the most common presentation of AUB. Adequate samples were obtained in 86% of cases while 13.9% of cases' sample was inadequate for opinion, many of which were later underwent hysteroscopy and/or dilatation and curettage (D and C in operation theater; atrophic endometrium was the most common cause for inadequate sample. Uterine malignancy was diagnosed in three cases. Discussion: Endometrial aspiration has been compared with traditional D and C as well as postoperative histopathology in various studies with good results. Many such studies are done in India as well as in western countries confirming good correlation with histopathology and adequate tissue sample for the pathologist to give a confident diagnosis. No complication or side effect was noted with the use of this device. Conclusion: Endometrial aspiration is a simple, safe, and

  13. Successful treatment of low-grade endometrial cancer in premenopausal women with an aromatase inhibitor after failure with oral or intrauterine progesterone

    2017-08-01

    Full Text Available Introduction: Young women with endometrial intraepithelial hyperplasia or low-grade endometrial carcinoma are potential candidates for conservative fertility sparing therapy utilizing progesterone rather than hysterectomy. High-dose progesterone treatment is associated with 55–80% initial response but high relapse rates. Using aromatase inhibitors in conjunction with high-dose progesterone has largely been unstudied. Case descriptions: Three obese premenopausal women with endometrial cancer failed to respond to oral or intrauterine progesterone as first line therapy. Due to their desire to continue to pursue fertility sparing treatment options, an aromatase inhibitor was added to their treatment regimen. This resulted in resolution of their malignancy in each case. Discussion: In obese premenopausal women, the mechanism of malignant transformation in endometrial carcinoma is considered to be an association with relatively high levels of serum estrogen from peripheral conversion of androgens to estrone in adipose tissue with a deficiency in progesterone exposure due to chronic anovulation. Using aromatase inhibitors seems reasonable as an adjunct to progesterone given the high likelihood that this population has a significant proportion of their estrogen production coming from peripheral conversion in adipose tissue. This case series is unique in that each woman initially failed to respond to progesterone but had resolution when an aromatase inhibitor was added to their treatment regimen. This would suggest that obese women with low grade malignancy or hyperplasia who have no radiographic evidence of deep myometrial invasion, ovarian or retroperitoneal metastases and who wish to retain their fertility may be treated with intrauterine progesterone and an aromatase inhibitor.

    The purpose of this study was to evaluate the clinicopathological characteristics and survival outcomes of women with simultaneous endometrial and ovarian carcinomas having the same histopathologic type. A review of medical records from 1997 to 2015 identified 72 patients with simultaneous carcinomas of the endometrium and ovary with the same histopathologic type. Patients with synchronous primary cancers of endometrium and ovary (SCEOs) were compared with patients with primary endometrial cancer with ovarian metastasis (ECOM). Clinical and pathological data were obtained from the patients' medical records. Clinicopathological variables including categorical data were analyzed by χ(2) or Fisher exact test and continuous data by a Student t test. A Kaplan-Meier survival analysis was performed and compared by using the log-rank test. A univariate and multivariate analysis of 72 patients with SCEO with the same histopathologic type revealed that SCEO is an independent prognostic factor of 10-year overall survival. There were 31 patients in the SCEO group and 41 patients in the ECOM group. With a mean follow-up time of 68.2 months, the 10-year overall survival rates were 61.3% and 36.6% in SCEO and ECOM groups, respectively (P = 0.029). Age, menopausal status, stage of ovarian cancer, performing lymphadenectomy, grade of endometrial tumor, omental metastasis, and residual tumor were found to be significant risk factors for recurrence in the synchronous group. The differentiation between SCEO and ECOM is of great clinical importance while our results showed a better prognosis for patients with SCEO compared with patients with ECOM. More aggressive therapeutic approaches may be considered for patients with SCEO who are older, postmenopausal, and/or have advanced grade of endometrial tumor, omental metastasis, and residual tumor. Lymphadenectomy should be performed in every patient with SCEO.

    Highlights: • IL-6 could promote endometrial cancer cells proliferation. • IL-6 promotes its own production through an autocrine feedback loop. • ERK and NF-κB pathway inhibitors inhibit IL-6 production and tumor growth. • IL-6 secretion relies on the activation of ERK–NF-κB pathway axis. • An orthotopic nude endometrial carcinoma model confirms the effect of IL-6. - Abstract: Interleukin (IL)-6 as an inflammation factor, has been proved to promote cancer proliferation in several human cancers. However, its role in endometrial cancer has not been studied clearly. Previously, we demonstrated that IL-6 promoted endometrial cancer progression through local estrogen biosynthesis. In this study, we proved that IL-6 could directly stimulate endometrial cancer cells proliferation and an autocrine feedback loop increased its production even after the withdrawal of IL-6 from the medium. Next, we analyzed the mechanism underlying IL-6 production in the feedback loop and found that its production and IL-6-stimulated cell proliferation were effectively blocked by pharmacologic inhibitors of nuclear factor-kappa B (NF-κB) and extra-cellular signal-regulated kinase (ERK). Importantly, activation of ERK was upstream of the NF-κB pathways, revealing the hierarchy of this event. Finally, we used an orthotopic nude endometrial carcinoma model to confirm the effects of IL-6 on the tumor progression. Taken together, these data indicate that IL-6 promotes endometrial carcinoma growth through an expanded autocrine regulatory loop and implicate the ERK–NF-κB pathway as a critical mediator of IL-6 production, implying IL-6 to be an important therapeutic target in endometrial carcinoma.

    Full Text Available Abstract Background The treatment strategy of central lung tumors is not established. Intraluminal brachytherapy (ILBT is widely used for palliative treatment of endobronchial tumors, however, it is also a promising option for curative treatment with limited data. This study evaluates the results after ILBT for endobronchial carcinoma. Method Sixteen-endobronchial carcinoma of 13 patients treated with ILBT in curative intent for 2000 to 2008 were retrospectively reviewed. ILBT using high dose rate 192 iridium thin wire system was performed with 5 Gy/fraction at mucosal surface. The patient age ranged from 57 to 82 years old with median 75 years old. The 16 lesions consisted of 13 central endobronchial cancers including 7 roentgenographically occult lung cancers and 3 of tracheal cancers. Of them, 10 lesions were treated with ILBT of median 20 Gy combined with external beam radiation therapy of median 45 Gy and 6 lesions were treated with ILBT alone of median 25 Gy. Results Median follow-up time was 32.5 months. Two-year survival rate and local control rate were 92.3% and 86.2%, respectively. Local recurrences were observed in 2 lesions. Three patients died due to lung cancer (1 patient and intercurrent disease (2 patients. Complications greater than grade 2 were not observed except for one grade 3 dyspnea. Conclusions ILBT combined with or without EBRT might be a curative treatment option in inoperable endobronchial carcinoma patients with tolerable complication.

    The results of radiotherapeutic treatment in 71 patients with squamous cell carcinoma of the cheek mucosa were reviewed. The actuarial 5-year local control rate was 100% for T1 (8 patients), 62% for T2 (43), 65% for T3 (17) and 0% for T4 (3). The patients were divided into four groups according to treatment modality; group 1 was treated by radiotherapy alone (R), group 2 by radiotherapy combined with chemotherapy of BLM or PEP (R + C), group 3 by external radiotherapy followed by surgery (R + S) and group 4 by a combination of radiotherapy, chemotherapy and surgery (R + C + S). The 5-year local control rate was 44% for R (11 patients), 61% for R + C (39), 63% for R+ S (6) and 80% for R + C + S (15). Nine of 14 cases or 64% of the surgical specimens in the R + C + S group showed no tumor cells microscopically, a rate comparable with the 5-year local control rate of the R + C group. Including the results of secondary treatment by surgery for recurrent cases, the ultimate local control rate was 83% in both the R and R + C groups. The local control rate was 88% for carcinoma located in the anterior half of the cheek and 53% for that in the posterior cheek. The results suggested that tumors extending to the bucco-alveolar sulci would be more difficult to control by radiotherapy alone, with or without chemotherapy. (author)

    The aim of this study was to assess the utility of liquid-based cytologic preparation (LP) compared with conventional preparation (CP) for the assessment of nuclear findings in endometrial glandular and stromal breakdown (EGBD) which may be misdiagnosed as carcinoma in EGBD cases. The material consists of cytologic smears including 20 cases of proliferative endometrium (PE), 20 cases of EGBD, and 20 cases of endometrioid adenocarcinoma grade1 (G1) for which histopathological diagnosis was obtained by endometrial curettage at the JA Suzuka General Hospital. Nuclear findings were examined in PE cells, EGBD-stromal cells, EGBD-metaplastic cells, and G1 cells, respectively. It was examined about the following items; (1) nuclear shape; (2) A long/minor axis ratio in cell nuclei; (3) an area of cell nuclei; (4) overlapping nuclei. Results are as follows: (1) nuclear shape; as for the reniform shape of EGBD-stromal cells and spindle shape of EGBD-metaplastic cells, the ratio of the LP method was a higher value than the CP method. (2) The long axis and area of cell nuclei; LP in all groups was a recognizable tendency for nuclear shrinkage. (3) The long/minor axis ratio in cell nuclei; only EGBD-metaplastic cells recognize a significant difference between CP and LP. (4) Overlapping nuclei; LP was a higher value in comparison with CP in the other groups except PE cells, and the degree of overlapping nuclei was enhanced about three times. Therefore, although a cell of LP has a shrinking tendency, (1) it is excellent that LP preserves a characteristic of nuclear shape than CP; (2) a cellular characteristic becomes clearer, because three-dimensional architecture of LP is preserved of than CP. As for the standard preparation method for endometrial cytology samples, we considered that a concrete introduction of the LP method poses no problems. Copyright © 2011 Wiley Periodicals, Inc.

    Endometrial cancer is one of the more frequent and most lethal gynaecological cancer types. Since it occurs more frequently in elderly and overweight patients, a pre-operative staging method would be beneficial. The growth of solid neoplasms is always accompanied by neovascularisation. Tumour endothelial markers (TEMs) are a group of recently described endothelial cell surface markers that appear to be specific to neoplastic tissue. This study aimed to investigate the potential usefulness of TEM assessment in the endometrium by comparing the transcriptional expression of TEMs in the normal endometrium with endometroid adenocarcinoma tissue. Tissues were lysed and the RNA was extracted, assessed and reverse transcribed in one batch. Real-time quantitative PCR was performed for TEM-1, -2, -6, -7, -7r and -8. GAPDH, β-actin and ribosomal protein L13A (RPL13A) were used as control genes. TEM-8 showed the highest expression level in all of the groups. TEM-1 showed higher expression levels in the normal endometrium than in the tumour tissues. For the remaining TEMs, we found a higher expression in the cancer samples than in the normal endometria. Statistical significance of this difference was achieved for TEM-1, -2 and-7. No clear correlation was noted between the tumour stage and the level of TEM-1, -6 and -8 expression. Apart from TEM-6, the highest expression in FIGO I cancer stages was noted in the remaining TEMs. Our results showed that for most of these tumour endothelial markers, gene expression was slightly higher in the endometrial carcinoma tissue samples than in the endometrium of normal cycling women. However, with the possible exception of TEM-8 and -6, absolute expression levels were generally low, indicating that most TEMs may only be specifically expressed in a restricted number of cancer types (e.g., colorectal). Therefore, TEMs may not be useful in the context of endometrial cancer. PMID:22966283

    Purpose We retrospectively analyzed anatomo-clinic, therapeutic and progressive particularities of 74 young patients (= 20 years) with nasopharyngeal carcinoma treated between 1993 and 2005. Patients and methods Initial work-up included a fiberoptic naso-fiberscopy with biopsy, computed tomography and/or MRI of nasopharynx and neck, chest X-ray, abdominal ultrasonography and bone scan. Patients were treated with either primary chemotherapy (epirubicin and cisplatin) followed by radiotherapy or concomitant radio chemotherapy (five fluorouracil and cisplatin). Radiotherapy was delivered to a total dose of 70 to 75 Gy to nasopharynx and involved cervical lymph nodes and 50 Gy to the remainder cervical areas. Results The median age was 16 years. Sixty-three percent of patients had undifferentiated tumors. Sixty-six percent had locally advanced tumor. With a median follow-up of 107 months, one patient presented a local relapse, 24 patients developed distant metastases with a median delay of 7 months. The 5 years overall survival and disease-free survival were 66 and 65 %. Late complications were dominated by dry mouth and endocrine disorders. Comments Pediatric nasopharyngeal carcinoma is characterized by an early metastatic diffusion. Local control is excellent but with severe late toxicities. New techniques of radiotherapy and new molecules of chemotherapy could improve these results. (authors)

    Purpose: P53 gene mutations are the common genetic changes encountered in human cancers, and there is extensive evidence that the P53 status may determine tumor response to therapy. This study was carried out to investigate whether there is any correlation between accumulation (overexpression) of P53 protein and poor prognosis in patients with head and neck carcinomas treated with radical radiotherapy. Methods and Materials: Seventy-nine patients with head and neck carcinomas who were diagnosed and treated in 1989-90 with curative radiotherapy were studied retrospectively. Paraffin sections from archival material were studied using immunohistochemical staining (IHC) with mouse monoclonal antibodies (D0-7) to human P53 protein. Univariate and multivariate analysis of loco-regional tumor control and patient survival were performed on possible prognostic factors. Results: Forty-two (53%) patients showed positive IHC staining in their tumors. Fifty-three percent of the laryngeal, 64% of the oropharyngeal, and 43% of the oral cavity carcinomas showed P53 overexpression. All tumor specimens with vascular, lymphatic, and/or sarcolemmal invasion showed P53 overexpression. The proportion of tumor-stained nuclei was higher in the poorly differentiated than in the well and moderately differentiated tumors (p < 0.05), but there was no correlation with the patient overall or disease-free 5-year actuarial survival. There was no difference in the 5-year actuarial survival and disease-free survival between patients with P53 immunostaining in their tumors and those with no immunostaining (59% vs. 65% and 57% vs. 51%, respectively). The TNM tumor stage was the most significant prognostic factor with 5-year actuarial survival of 87% for early and 14% for late stages (p << 0.0001). There was a significant correlation between immunostaining and history of smoking (p = 0.02). Conclusion: The data demonstrate that the P53 accumulation as detected by immunohistochemical staining in a

    This study evaluates the data of noninvasive (in situ) lobular (ISLC) and ductal (ISDC) carcinoma, collected from 498 hospitals in a National Breast Cancer Survey, carried out by the American College of Surgeons in 1978. ISLC and ISDC were identified in 323 (3.2%) of 10,054 female patients with lobular and ductal carcinoma, of the total of 23,972 patients with histologically proven breast cancer surveyed (1.4%). The frequency of ISLC was significantly higher (18.5%) than ISDC (2.1%) suggesting a less agressive nature of ISLC, with a slower progression to invasion than ISDC. There was a different age distribution of ISLC and ISDC: about 80% of ISLC and 50% of ISDC were diagnosed in patients who were less than 54 years old, and the incidence showed a marked decrease in the older age groups in ISLC, whereas the incidence remained high in the following decade in ISDC. In this series there was a distinctly better five-year cure rate in the patients with ISLC (83.5%) than in the patients with ISDC (68.8%), in spite of the fact that radical surgery was performed more frequently in ISDC (67.8%) than ISLC (36.3%). The recurrence rate was five times higher (10.5%) in ISDC than in ISLC (2.5%). In black patients the recurrence rate (21.3%) was significantly higher in ISDC than in white patients (9.3%). In the present study there were no statistically significant differences in the five-year cure and recurrence rate in patients with noninvasive carcinoma, treated by more conservative procedures (72.9% and 8.5%) and those treated by more extensive surgeries (76.2% and 7.7%). The results of this study suggests that the biologic behavior of ISLC and ISDC may be different with regard to their propensity to invade and their overall prognosis. In contrast, the infiltrative form of lobular and ductal carcinoma, were found to have the same prognosis, regardless of the type of operative procedure performed. PMID:6250497

    Endometrial cancer is the fourth most common cancer in European women. The major risk factors for endometrial cancer are related to the exposure of endometrium to estrogens not opposed to progestogens, that can lead to a chronic endometrial inflammation. Diet may play a role in cancer risk by modulating chronic inflammation. In the framework of a case-control study, we recruited 297 women with newly diagnosed endometrial cancer and 307 controls from Northern Italy. Using logistic regression, we investigated the role of fruit and vegetable intake, adherence to the Mediterranean diet (MD), and the dietary inflammatory index (DII) in endometrial cancer risk. Women in the highest quintile of vegetable intake had a statistically significantly lower endometrial cancer risk (adjusted OR 5th quintile vs 1st quintile: 0.34, 95% CI 0.17-0.68). Women with high adherence to the MD had a risk of endometrial cancer that was about half that of women with low adherence to the MD (adjusted OR: 0.51, 95% CI 0.39-0.86). A protective effect was detected for all the lower quintiles of DII, with the highest protective effect seen for the lowest quintile (adjusted OR 5th quintile vs 1st quintile: 3.28, 95% CI 1.30-8.26). These results suggest that high vegetable intake, adherence to the MD, and a low DII are related to a lower endometrial cancer risk, with several putative connected biological mechanisms that strengthen the biological plausibility of this association.

    The early carcinoma of the uterine cervix may be treated by either radical surgery or radical radiotherapy according to the patient characteristics, and the survival is high with either treatment. But, because of the size of the lesion, metastasis to lymph nodes, and vascular space invasion by tumor have all been shown to influence recurrence and survival, postoperative radiotherapy may be considered as their histopathologic finding after radical surgery. However, there are still debates on the increasing survival rates with postoperative radiotherapy. Two hundreds and three patients with carcinoma of the uterine cervix who were treated with postoperative radiotherapy from February 1979 to September 1982 in the Department of Therapeutic Radiology, Seoul National University were analyzed and following results were obtained. 3-year actuarial survival rate and 3-year disease free survival rate were 83.4% and 73.4% respectively and 3-year actuarial survival rates by stages were 90.7% for I B, 69.6% for II A, and 85.2% for II b. The overall acute complication rate was 57.6%; tolerable cases was 50.2% and severe cases was 7.4%, Late complication rate was 7.9% and the major late complication were intestinal obstruction, aggravated urinary symptom, radiation cystitis in ORDER of frequency

    The prospective record of acute and late toxicity after treatment of cervix carcinomas is a part of the description of treatment outcome as well as local control and survival. Due to the large number of scales and glossaries used, the comparison of the results from one study to another is often difficult. The French-Italian syllabus seems to be the most reliable scale, providing implementation of quality of life assessment. The main predictive factor of complications, which is not related to the treatment type, is the previous history of abdominal or pelvic surgery. The incidence and severity of complications occurring after surgery are related to the surgical procedure and to the amount of peri-uterine tissues removed. The increase in dose and volume of external irradiation and brachytherapy and the increase in dose rate of the low-dose rate brachytherapy are responsible for the radiotherapeutic morbidity. The significant decrease of severe complication rates during the last 15 years was obtained by the implementation of individual adjustments in treatment planning. The treatment strategies of early bulky and advanced carcinomas are changing. Concurrent radiotherapy and chemotherapy is becoming a standard, but its late toxicity needs to be documented by a longer follow-up. The optimisation of radiation therapy should remain a reference to evaluate the outcome and morbidity of the new combined strategies: the addition of chemotherapy will never compensate for less than optimal radiotherapy/brachytherapy planning.

    The goal of the current study was to understand and document contemporary treatment approaches in the management of ductal carcinoma in situ (DCIS). An original questionnaire was designed to assess radiation oncologists' management of breast carcinoma, including 26 questions specifically addressing DCIS. A postal survey was conducted of members of the American and European Societies of Therapeutic Radiology and Oncology. The results of 702 responses from North America were compared with 435 responses from Europe, to determine treatment recommendations and variability by type of institution and geographic region. There were strong correlations between the grade of DCIS and/or the margin status and the use of radiotherapy (RT; P variations in physician recommendations for tamoxifen (P < 0.001), but not in the tendency to recommend RT. North American academic physicians were less likely to recommend RT for favorable DCIS than nonacademic physicians (P < 0.01). There were marked differences in physician opinions regarding the management of DCIS, with significant international differences in patterns of care. The survey quantified and highlighted areas of agreement and controversy regarding the use of RT and tamoxifen in the management of DCIS. It provided support for large international trials to evaluate the optimal management of DCIS in the areas identified as most controversial.

    From February 1982-June 1986, 25 consecutive patients with surgical stage I endometrial adenocarcinoma (no evidence of metastasis at surgery or occult cervical or adnexal involvement on histopathologic review) and malignant peritoneal cytologic washings were treated with progesterone therapy. Twenty-two patients have undergone a second look laparoscopy and repeat cytologic washings, one of those also underwent a third look laparoscopy. Two patients refused second look laparoscopy, and in a third patient laparoscopy was medically contraindicated; all three have no evidence of disease (NED) at 15, 46, and 64 months respectively and are off therapy. Of the 22 patients who underwent second look laparoscopy, 21 (95%) had no macroscopic evidence of recurrent endometrial carcinoma and repeat negative peritoneal cytology; 1 patient (5%) had persistent malignant peritoneal cytology but was NED at third look laparoscopy one year later. All 25 patients are off progesterone therapy and remain clinically NED from 12-64 months. Although progesterone therapy for malignant peritoneal cytology resulted in a 100% reversal of malignant peritoneal cytology to normal in the 22 patients who underwent second or third look laparoscopy and all 25 patients remain clinically NED, the true value of progesterone therapy can only be ascertained by a randomized trial of progesterone versus no therapy.

    Endometrial adenocarcinomas rank third as tumoral sites en France. The tumors are confined to the uterus in 80% of the cases. Brachytherapy has a large place in the therapeutic strategy. The gold standard treatment remains extra-fascial hysterectomy with bilateral annexiectomy and bilateral internal iliac lymph node dissection. However, after surgery alone, the rate of locoregional relapses reaches 4-20%, which is reduced to 0-5% after postoperative brachytherapy of the vaginal cuff. This postoperative brachytherapy is delivered as outpatients treatment, by 3 or 4 fractions, at high dose rate. The utero-vaginal preoperative brachytherapy remains well adapted to the tumors which involve the uterine cervix. Patients presenting a localized tumor but not operable for general reasons (< 10%) can be treated with success by exclusive irradiation, which associates a pelvic irradiation followed by an utero-vaginal brachytherapy. A high local control of about 80-90% is obtained, a little lower than surgery, with a higher risk of late complications. Last but not least, local relapses in the vaginal cuff, or in the perimeatic area, can be treated by interstitial salvage brachytherapy, associated if possible with external beam irradiation. The local control is reached in half of the patients, but metastatic dissemination is frequent. We conclude that brachytherapy has a major role in the treatment of endometrial adenocarcinomas, in combination with surgery, or with external beam irradiation for not operable patients or in case of local relapses. It should use new technologies now available including computerized after-loaders and 3D dose calculation. (authors)

    Restaging in epithelial ovarian carcinoma after primary therapy has proven difficult by standard noninvasive methods and commonly requires second-look laparotomy. In the authors' study to date preoperative abdominopelvic CT (CBT) results and operative findings have been compared in 24 patients (25 studies) with ovarian adenocarcinoma currently clinically free of disease originally graded as FIGO stage III or IV, except for one patient with stage IC, undergoing second-look laparotomy to determine tumor status. There were ten true-negative, three false-negative, 12 true-positive, and no false-positive CBTs. Negative studies were associated with positive findings at laparotomy, including microscopic foci, in only 12% of all cases; thus, CBT in the series has shown a better correlation with surgery than in previous studies. Currently the authors are combining monoclonal antibody scanning with the CBT results with the goal of possibly avoiding second-look surgery in certain patients

    In 1979 the Cancer Control Agency of British Columbia changed from radium to remote controlled afterloaded caesium in the treatment of carcinoma of the cervix. In 3 years prior to the change, 139 patients received radium as part of their treatment and in the 3 years after the change, 158 patients received caesium. Overall referral patterns, patient and cancer demographics, and treatment policies were stable throughout the 6-year period. Radiotherapy technique, dose, dose distribution and dose rate were comparable for both radium and caesium treated patients. The results of treatment in the two time periods showed no difference in survival, local tumour control or complications. The use of afterloading has not compromised treatment results and has allowed better nursing care for patients and protection from radiation for all staff. (author)

    Purpose: This course will review current staging, prognostic factors, treatment options, rationale and management strategies for patients with endometrial carcinoma. Carcinoma of the endometrium is the most common gynecological malignancy in the U.S. About 40,000 new cases are diagnosed each year. The majority of the patients at the time of diagnosis have early stage disease. Staging of endometrial cancer has been modified three times by FIGO over the past 25 years. Materials and Methods: Various treatment options will be reviewed and current available literature on results and complications of various treatments will be discussed. The standard treatment for operable patients with carcinoma of the endometrium is total abdominal hysterectomy-bilateral salpingoopherectomy with regional lymph node staging. There is considerable controversy regarding the role of radiation as an adjuvant treatment. Various combinations of surgery and radiation have been used in the past. With better knowledge and understanding of the natural history of the disease and significance of prognostic factors, three different risk groups have been identified; low risk, intermediate risk, high risk. Postoperative radiation has been shown to decrease local failures and improve survival in the majority of the intermediate risk group and high risk group of patients. There is considerable controversy on the role of intravaginal radiation. Considerable experience has been accumulated in the use of High Dose Rate fractionated intravaginal treatment. Results: The results of combined surgery and radiation treatment have been very satisfactory with associated minimal complication rate. The long term published data on results and complications will be discussed. Conclusion: Various treatment strategies for different prognostic groups will be discussed. The advantages and disadvantages of low dose rate versus high dose rate brachytherapy, intracavitary versus external beam radiation therapy will be

    Purpose: To evaluate the results of salvage radiotherapy (RT) after inadequate surgery in patients with invasive carcinoma of the cervix. Methods and Materials: Between 1996 and 2001, 105 invasive cervical carcinoma patients were treated at our center with external beam RT with or without intracavitary RT after having undergone total/subtotal hysterectomy at outside institutions. Results: The median follow-up was 34 months. The gap between surgery and RT was 23-198 days (median, 80). Clinically visible residual disease was present in 81 patients (77.1%). Total hysterectomy had been done in 82 patients (78%) and subtotal hysterectomy in 23 patients (22%). The 5-year overall survival, disease-free survival, and pelvic control rates of all patients were 55.2%, 53.3%, and 72.4%, respectively. On univariate analysis, older age, total hysterectomy, hemoglobin level >10 g% before RT, nonsquamous histologic type, use of intracavitary RT, a shorter gap between surgery and RT, and the absence of, or a small volume of, residual disease favorably affected the outcome. The 5-year actuarial rate of late toxicity (Radiation Therapy Oncology Group Criteria) was 19% in the rectum, 4.8% in the bladder, 24.8% in the skin, and 14.3% in the small intestine. Conclusions: Inadequate and inappropriate surgery in invasive cervical cancer with resulting gross residual disease is common in India. Factors such as the use of intracavitary RT, the correction of anemia, and a shorter gap between surgery and RT will enable postoperative RT to achieve acceptable results with minimal morbidity

    Purpose. -- The objective of this retrospective study was to discuss the epidemio-clinical criteria and the therapeutic results of metastatic nasopharyngeal carcinoma. Patients and methods. - The current study concerned 95 patients with histologically proven nasopharyngeal carcinoma who were metastatic at diagnosis or who had developed late metastasis. We reviewed the epidemio-clinical records of all the patients. Patients were treated with chemotherapy (BEC regimen: bleomycin, epirubicin and cisplatin or PBF regimen: bleomycin, 5-fluorouracil and cisplatin) and radiotherapy of pauci metastatic localizations (single or double) or bone metastasis with high risk of compression or fracture ±associated with locoregional radiotherapy for patients who were metastatic at diagnosis. Response was assessed according to the WHO criteria. Overall survival was calculated according to the Kaplan-Meier method. A long-term disease-free survival was defined from 36 months. Results. - There were 34 patients who were metastatic at diagnosis and 61 patients who had developed late metastasis. The mean age was 41.5 years (sex-ratio: 3.1). Bone metastases were the most frequent (83%). Objective and complete response rates were respectively 75% and 70%, and 32% and 16% for BEC and PBF regimens. Twenty-five patients received radiotherapy for pauci metastatic localizations, among whom 19 patients who were metastatic at diagnosis received locoregional irradiation. The overall survival probability was of 15% for three years. Eleven patients were long survivors (extremes: 36 and 134 months). Conclusion. - Therapeutic results were comparable to those reported in other series using platin combination chemotherapy. Radiotherapy of metastasis yielded to long-term survival. (authors)

    Full Text Available BACKGROUND: The presence of conceptus alloantigens necessitates changes in maternal immune function. One player in this process may be the macrophage. In the cow, there is large-scale recruitment of macrophages expressing CD68 and CD14 to the uterine endometrium during pregnancy. METHODOLOGY/PRINCIPAL FINDINGS: In the present study, the function of endometrial macrophages during pregnancy was inferred by comparison of the transcriptome of endometrial CD14(+ cells isolated from pregnant cows as compared to that of blood CD14(+ cells. The pattern of gene expression was largely similar for CD14(+ cells from both sources, suggesting that cells from both tissues are from the monocyte/macrophage lineage. A total of 1,364 unique genes were differentially expressed, with 680 genes upregulated in endometrial CD14(+ cells as compared to blood CD14(+ cells and with 674 genes downregulated in endometrial CD14(+ cells as compared to blood CD14(+ cells. Twelve genes characteristic of M2 activated macrophages (SLCO2B1, GATM, MRC1, ALDH1A1, PTGS1, RNASE6, CLEC7A, DPEP2, CD163, CCL22, CCL24, and CDH1 were upregulated in endometrial CD14(+ cells. M2 macrophages play roles in immune regulation, tissue remodeling, angiogenesis and apoptosis. Consistent with a role in tissue remodeling, there was over-representation of differentially expressed genes in endometrium for three ontologies related to proteolysis. A role in apoptosis is suggested by the observation that the most overrepresented gene in endometrial CD14(+ cells was GZMA. CONCLUSIONS: Results indicate that at least a subpopulation of endometrial macrophages cells differentiates along an M2 activation pathway during pregnancy and that the cells are likely to play roles in immune regulation, tissue remodeling, angiogenesis, and apoptosis.

    The protocol and result were described of chemotherapy and radiotherapy for locally advanced esophageal carcinoma, especially for A3 stage one with metastasis at neighboring tissues such as aorta, trachea and bronchia. Chemotherapy was done with 5-FU and CDDP and radiotherapy, with 30 Gy/15 fx/3 wk. Double contrast roentgenography, dynamic CT and MRI were performed to follow the process. The efficacy rate was 55.0% with 4 CR and 7 PR in 20 cases. Three CR patients survived at present. Major adverse effects were leukopenia and thrombocytopenia, of which grade 4 were found in 14 and 12% cases, respectively. Low-dose FP therapy might be useful for lowering the adverse effects and for elevating the efficacy rates. (K.H.)

    Full Text Available Objective: To assess the value of diagnostic hysteroscopy with biopsy in the preoperative preparation for endometrial ablation. Methods: It was a prospective non-randomized study conducted at the division of Gynecologic Endoscopy of Hospital do Servidor Público Estadual “Francisco Morato de Oliveira” from March 2007 to May 2009. A total of 45 patients with abnormal uterine bleeding, and referred to endometrial ablation were included. All women underwent a diagnostic hysteroscopy, and were treated with a GnRH analogous – goserelin – 10.8 mg before surgery. The endometrial ablation was performed with a surgical resectoscope. Patients were submitted to one directed endometrial biopsy, one guided endometrial biopsy with Novak curette, and to endometrial ablation, which was considered as reference for pathological examination with samples from the biopsies. Data were analyze using the SPSS-v16 software, and considered significance at p = 0.05. Results: The mean age of women was 44.20 years (33-56, parity of 2.67 (0-9, uterus size of 139.99 calculated in cc (42-278, and the mean duration of symptoms was 3.68 years (0.5-15. The guided endometrial biopsy showed sensitivity of 80% for endometrium without atypia, and the directed endometrial biopsy had sensitivity of 60%. For proliferative endometrium the directed endometrial biopsy showed sensitivity of 76 and 100% for secretory endometrium, which was higher than the guided endometrial biopsy with 53 and 50%, respectively. Conclusion: The directed biopsy before endometrial ablation had lower sensitivity than guided biopsy for endometrium without atypia, however it was higher for proliferative and secretory endometrium.

    Children with multiple endocrine neoplasia type 2 (MEN2) often develop medullary carcinoma of the thyroid (MCT) or its precursor, C-cell hyperplasia. Survival results are improved if malignancy is diagnosed early from the results of plasma immunoreactive calcitonin (iCT) measurement. The effect of early detection and thyroidectomy in children with MEN2 syndrome was determined by reviewing the experience between 1975 and 1985. Seventeen children with MEN2 who were 12 years old or younger underwent a total thyroidectomy for MCT or C-cell hyperplasia. iCT was measured in all patients preoperatively and postoperatively. Of the 17 children, 14 (82%) had MEN2a and 3 (18%) had MEN2b. There were 14 (82%) female and three (18%) male patients; their mean age was 6.97 years (range 1.5 to 12 years). In all patients, the diagnosis of MCT was made from initial elevated levels of iCT after stimulation with pentagastrin. Three patients had clinical evidence of disease preoperatively. All patients underwent a total thyroidectomy and lymph nodes were removed from the central zone; a neck dissection was performed in the three with clinically obvious disease. MCT with C-cell hyperplasia was found in 11 children and C-cell hyperplasia alone in six. Of the 11 with carcinoma, eight had bilateral disease and three unilateral. Six children had bilateral C-cell hyperplasia. All 17 children were alive and feeling well at the time of this report; however, three had evidence of metastatic disease according to iCT measurements. None of the children had recurrent nerve injuries; one had evidence of hypoparathyroidism.(ABSTRACT TRUNCATED AT 250 WORDS)

    Purpose: In 1991, we started a clinical prospective trial for operable esophageal carcinoma, foreseeing organ preservation, to assess the treatment results after definitive chemoradiotherapy (Crt) for clinical Stage I (Taman) esophageal cancer. Patients and Methods: Between 1992 and 2003, 63 patients were enrolled in this study. Tumor depth was mucosal cancer (T 1a) in 23 and submucosal cancer (T 1b) in 40. Crt consisted of 55-66 Gy/50-60 fractions (median, 59.4 Gy); from 1 to 3 cycles (median, 2) of concurrent chemotherapy (Cisplatin and 5-fluorouracil), followed by high-dose-rate intraluminal brachytherapy 10-12 Gy/2-3 fractions. Results: The 5-year overall and cause-specific and disease-free survival rates were 66.4%, 76.3%, and 63.7%, respectively. The 5-year cause-specific survival rates for T 1a and T 1b cancer patients were 85.2% and 70.0%, respectively (p = 0.06). The 5-year disease-free survival rates for T 1a and T 1b were 84.4% and 50.5%, respectively (p < 0.01). Esophageal fistula as a late toxicity occurred in 2 patients (G: 1; G: 1), and esophageal stricture requiring a liquid diet occurred in 2 patients. Pericardial effusion was observed in 3 patients. Conclusion: We confirmed that patients with Taman esophageal carcinoma had their esophagus preserved in 89.2% of cases after definitive Crt, and the survival rates were equivalent to those of previous reports of surgery

    Clinical screening criteria, such as young age of endometrial cancer diagnosis and family history of signature cancers, have traditionally been used to identify women with Lynch Syndrome, which is caused by mutation of a DNA mismatch repair gene. Immunohistochemistry and microsatellite instability analysis have evolved as important screening tools to evaluate endometrial cancer patients for Lynch Syndrome. A complicating factor is that 15-20% of sporadic endometrial cancers have immunohistochemical loss of the DNA mismatch repair protein MLH1 and high levels of microsatellite instability due to methylation of MLH1. The PCR-based MLH1 methylation assay potentially resolves this issue, yet many clinical laboratories do not perform this assay. The objective of this study was to determine if clinical and pathologic features help to distinguish sporadic endometrial carcinomas with MLH1 loss secondary to MLH1 methylation from Lynch Syndrome-associated endometrial carcinomas with MLH1 loss and absence of MLH1 methylation. Of 337 endometrial carcinomas examined, 54 had immunohistochemical loss of MLH1. 40/54 had MLH1 methylation and were designated as sporadic, while 14/54 lacked MLH1 methylation and were designated as Lynch Syndrome. Diabetes and deep myometrial invasion were associated with Lynch Syndrome; no other clinical or pathological variable distinguished the 2 groups. Combining Society of Gynecologic Oncology screening criteria with these 2 features accurately captured all Lynch Syndrome cases, but with low specificity. In summary, no single clinical/pathologic feature or screening criteria tool accurately identified all Lynch Syndrome-associated endometrial carcinomas, highlighting the importance of the MLH1 methylation assay in the clinical evaluation of these patients.

    This paper reports the experience obtained in the last 8 years with an instrument (articulated rotative brush) that allows access to the entire endometrial surface, obtaining material for both histological and cytological study. The latter has the advantage of reducing the number of cases in which insufficient material frustrates endometrial assessment. In addition to the overall experience gained with this instrument, the proportion of agreement with anatomo-pathological diagnosis after hysterectomy in 61 patients was high (96%) and the unweighted kappa statistic (0.862) indicated very good accordance between these techniques. Comparison between the present method and hysteroscopic observations in 84 patients with perimenopausal bleeding revealed a general conformity of 0.65 and an unweighted kappa statistic of 0.368 (fair agreement). In a group of 72 cases with postmenopausal bleeding a general conformity value of 0.92 was obtained, with an unweighted kappa statistic of 0.84 (very good agreement). In 90% of the cases the procedure was well accepted. In 57.3% of the cases, no difficulties were encountered using the brushing technique; in 25.9% slight dilatation was deemed necessary, whereas in 16.8% technical difficulties could not be overcome and general anesthesia was indicated. A total of 769 outpatients were investigated, 75.3% of which had normal endometria, 12.7% benign hyperplasias, 2.6% precursor lesions, 1.7% suspect carcinoma, and 4.2% carcinomas. Insufficient material for diagnosis occurred in 3.5% of cases tested. The combined cytohistological and hysteroscopic assessment of the endometrium provides satisfactory results in the etiological diagnosis of peri and postmenopausal bleeding, and in the follow up of patients undergoing hormonal replacement therapy (HRT).

    In this retrospective study the results of primary and salvage treatment of oropharyngeal carcinoma were evaluated. A total of 289 consecutive patients (103 females and 186 males) were included in the study. Most tumours originated in the tonsil area (58%) and comprised stages I 8%, II 19%, III 46% and IV 28%. The primary treatment was delivered with curative intent in 276 cases (96%). Of these, 266 received primary radiotherapy. The median radiation dose was 62 Gy, given as laterally opposed fields to the primary tumour and bilateral neck. Eight patients were treated with primary surgery and two with chemotherapy as part of a curatively intended treatment programme including radiotherapy. Six patients received palliative treatment, and seven were not treated at all. Out of 276 tumours treated with curative intent, 173 reappeared; 72% recurred in T position, 38% in N position, and 12% at distant metastatic sites, some in combination. Salvage surgery was possible in 52 patients, and 24 treatments were successful. Salvage radiotherapy or cryotherapy was used in 22 patients and 4 were controlled. For the entire group, the 5-year locoregional tumour control, disease-specific survival and overall survival rates were 38%, 44% and 31%, respectively. For patients treated with curative intent, clinical T- and N-stage, stage, tumour size, gender, age, and pretreatment haemoglobin were significant prognostic parameters in a univariate analysis. The Cox multivariate analysis showed that T-stage, N-stage and gender were independent prognostic factors. It is concluded that T-stage, N-stage and gender are significant independent prognostic factors. The primary control of the carcinoma in the T-position is crucial for overall success, but salvage surgery is found to have a favourable success rate in patients suitable for relapse treatment

    Hysterectomy and bilateral salpingo-oophorectomy (BSO) is the standard surgery for stage I endometrial cancer. Systematic pelvic lymphadenectomy has been used to establish whether there is extra-uterine disease and as a therapeutic procedure; however, randomised trials need to be done to assess therapeutic efficacy. The ASTEC surgical trial investigated whether pelvic lymphadenectomy could improve survival of women with endometrial cancer. From 85 centres in four countries, 1408 women with histologically proven endometrial carcinoma thought preoperatively to be confined to the corpus were randomly allocated by a minimisation method to standard surgery (hysterectomy and BSO, peritoneal washings, and palpation of para-aortic nodes; n=704) or standard surgery plus lymphadenectomy (n=704). The primary outcome measure was overall survival. To control for postsurgical treatment, women with early-stage disease at intermediate or high risk of recurrence were randomised (independent of lymph-node status) into the ASTEC radiotherapy trial. Analysis was by intention to treat. This study is registered, number ISRCTN 16571884. After a median follow-up of 37 months (IQR 24-58), 191 women (88 standard surgery group, 103 lymphadenectomy group) had died, with a hazard ratio (HR) of 1.16 (95% CI 0.87-1.54; p=0.31) in favour of standard surgery and an absolute difference in 5-year overall survival of 1% (95% CI -4 to 6). 251 women died or had recurrent disease (107 standard surgery group, 144 lymphadenectomy group), with an HR of 1.35 (1.06-1.73; p=0.017) in favour of standard surgery and an absolute difference in 5-year recurrence-free survival of 6% (1-12). With adjustment for baseline characteristics and pathology details, the HR for overall survival was 1.04 (0.74-1.45; p=0.83) and for recurrence-free survival was 1.25 (0.93-1.66; p=0.14). Our results show no evidence of benefit in terms of overall or recurrence-free survival for pelvic lymphadenectomy in women with early

    Objective: To compare the relative efficacy of histopathological examination and culture method in the diagnosis of endometrial tuberculosis. Design: It was a prospective, comparative in-vitro study. Place and Duration of Study: The study was conducted at the Armed Forces Institute of Pathology, Rawalpindi and Department of Obstetrics and Gynecology, Military Hospital, Rawalpindi from August 1998 to April 1999. Materiel and Methods: A total number of 50 cases of primary and secondary infertility were selected. Endometrial biopsies of all patients were subjected to histopathological as well as culture examination on BACTEC. Results: Culture method yielded 10% (n=5) positive results compared with 6% (n=3) positive results obtained by histopathological examination. P value was 0.096 by chi-square test. Conclusion: Culture is a more effective method compared with histopathological examination in the diagnosis of endometrial tuberculosis. (author)

    To determine whether the transvaginal sonographic appearance of the thickened endometrium can help to predict the underlying endometrial pathologic process. The sonogram reports of fall 41 pre- and 21 postmenopausal women who underwent transvaginal sonogram were retrospectively analyzed. The women undergoing estrogen replacement therapy, tamoxifen therapy or having abnormal cervical cytology were excluded from this study. The analysis of sonographic and histologic results was performed in all patients. Three distinct sonographic patterns were encountered. Type I consisted of heterogeneous endometrial thickening with internal hypoechoic areas (normal [n=4], polyp [n=1] and cancer [n=4] in premenopausal women and cancer [n=4] in postmenopausal women). Type II consisted of echogenic endometrial thickening with or without tiny cysts (normal[n=5], and hyperplasia [n=7] in premenopausal women and normal [n=4], polyp [n=2], and hyperplasia [n=1] in postmenopausal women). Type III consisted of localized well defined endoluminal lesion (normal [n=1], polyp [n=14], hyperplasia [n=1], cancer [n=1], and submucosal mass [n=3] in premenopausal women and normal [n=4], polyp [n=2],submucosal mass [n=3], and hematoma [n=1] in postmenopausal women). The measurement of the endometrial thickness combined with analysis of sonographic echo patterns may be helpful in prediction and differentiation of endometrial disease in pre- and postmenopausal women. Also it can contribute to avoiding unnecessary D and C.

    2017-01-01

    Objective To compare the diagnostic accuracy of transvaginal ultrasound (TVS) and magnetic resonance imaging (MRI) for detecting myometrial infiltration (MI) in endometrial carcinoma. Methods An extensive search of papers comparing TVS and MRI in assessing MI in endometrial cancer was performed in MEDLINE (PubMed), Web of Science, and Cochrane Database from January 1989 to January 2017. Quality was assessed using Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool. Results Our extended search identified 747 citations but after exclusions we finally included in the meta-analysis 8 articles. The risk of bias for most studies was low for most 4 domains assessed in QUADAS-2. Overall, pooled estimated sensitivity and specificity for diagnosing deep MI were 75% (95% confidence interval [CI]=67%–82%) and 82% (95% CI=75%–93%) for TVS, and 83% (95% CI=76%–89%) and 82% (95% CI=72%–89%) for MRI, respectively. No statistical differences were found when comparing both methods (p=0.314). Heterogeneity was low for sensitivity and high for specificity for TVS and MRI. Conclusion MRI showed a better sensitivity than TVS for detecting deep MI in women with endometrial cancer. However, the difference observed was not statistically significant. PMID:29027404

    Nasopharyngeal carcinoma (NPC) is a disease which is prevalent in developing countries like Indonesia. There were 164 new cases of nasopharyngeal carcinoma in the ear, nose, and throat (ENT) oncology outpatient clinic of the Cipto Mangunkusumo hospital in 2014, and 142 cases in 2015. Unfortunately, almost all of these cases presented at an advanced stage. The success of nasopharyngeal carcinoma treatment is largely determined by the stage when patients are diagnosed; it is critical to diagnose NPC as early as possible. Narrow-band imaging (NBI) is an endoscopic instrument with a light system that can improve the visualization of blood vessels of mucosal epithelial malignant tumors. NBI is expected to help clinicians to assess whether a lesion is malignant or not; to do so, it is important to know the value of sensitivity and specificity. This study is a cross-sectional form of a diagnostic test which was performed in the outpatient clinic of the ENT Head and Neck Surgery Department for the Cipto Mangunkusumo Hospital, from January to June 2016, and involved 56 subjects. Patients with a nasopharyngeal mass discovered by physical examination or imaging, and a suspected nasopharyngeal carcinoma were included as a subject. An NBI examination and biopsy was performed locally. Based on this research, NBI could be used as a screening tool for nasopharyngeal carcinoma with high sensitivity (100%), but with a low specificity result (6.7%).

    Our objective was to determine if a correlation exists between endometrial thickness measured on the day of ovulation trigger during an in vitro fertilization (IVF) cycle and pregnancy outcomes among non-cancelled cycles. We performed a retrospective cohort study looking at 6331 women undergoing their first, fresh autologous IVF cycle from 1 May 2004 to 31 December 2012 at Boston IVF (Waltham, MA). Our primary outcome was the risk ratio (RR) of live birth and positive β-hCG. We found that thicker endometrial linings were associated with positive β-hCG and live birth rates. For each additional millimetre of endometrial thickness, we found a statistically significant increased risk of positive β-hCG (adjusted RR: 1.14; 95% CI: 1.09-1.18) and live birth (RR: 1.08; 95% CI: 1.05-1.11). There was no association between endometrial thickness and miscarriage (RR: 0.99; 95% CI: 0.91-1.07). Similar results were seen when categorizing endometrial thickness. Compared with an endometrial thickness >7 to <11 mm, the likelihood of a live birth was significantly higher for an endometrial thickness ≥11 mm (adjusted RR: 1.23; 95% CI: 1.11-1.37) and significantly lower for the ≤7 mm group (adjusted RR: 0.64; 95% CI: 0.45-0.90). In conclusion, thicker endometrial linings were associated with increased pregnancy and live birth rates.

    Carcinoma of the endometrium is the most common malignant tumor in the female genital tract. Radiation therapy continues to play a major role in the management of endometrial carcinoma, both as primary therapy and as adjuvant treatment. The utility of pelvic external beam therapy and intracavitary therapy is long established. However, the modern era of surgical staging has lead to an appreciation of the role of radiation therapy beyond the pelvis. Radiation therapy has been shown to be of particular benefit in peritoneal and nodal spread. The classic management of endometrial cancer is reviewed and relatively new and somewhat controversial topics, such as preoperative intracavitary therapy followed by external beam therapy are discussed

    BACKGROUND: In 1975, estrogen only was found to be associated with an increased risk of endometrial cancer. In November 2015, NICE guidelines on hormone therapy were published that did not take this risk into account. AIM: This systematic literature review assesses the safety of estrogen plus...... progestin therapy according to the risk of endometrial cancer, while considering both regimen and type of progestin. METHODS: PubMed, EMBASE and the Cochrane Library were searched, resulting in the identification of 527 published articles on menopausal women with intact uteri treated with estrogen only......, estrogen plus progestin or tibolone for a minimum of one year. Risk of endometrial cancer was compared to placebo or never users and measured as relative risk, hazard or odds ratio. RESULTS: 28 studies were included. The observational literature found an increased risk among users of estrogen alone...

    Background: Nulliparity is an endometrial cancer risk factor, but whether or not this association is due to infertility is unclear. Although there are many underlying infertility causes, few studies have assessed risk relations by specific causes. Methods: We conducted a pooled analysis of 8153 cases and 11 713 controls from 2 cohort and 12 case-control studies. All studies provided self-reported infertility and its causes, except for one study that relied on data from national registries. Logistic regression was used to estimate adjusted odds ratios (OR) and 95% confidence intervals (CI). Results: Nulliparous women had an elevated endometrial cancer risk compared with parous women, even after adjusting for infertility (OR=1.76; 95% CI: 1.59–1.94). Women who reported infertility had an increased risk compared with those without infertility concerns, even after adjusting for nulliparity (OR=1.22; 95% CI: 1.13–1.33). Among women who reported infertility, none of the individual infertility causes were substantially related to endometrial cancer. Conclusions: Based on mainly self-reported infertility data that used study-specific definitions of infertility, nulliparity and infertility appeared to independently contribute to endometrial cancer risk. Understanding residual endometrial cancer risk related to infertility, its causes and its treatments may benefit from large studies involving detailed data on various infertility parameters.

    Full Text Available The peculiarities of benign proliferative pathology of endometrium including their combination in women of reproductive age are reviewed in the article. Materials and methods. The results of pathohistological research of benign proliferative pathology of endometrium (without atypia were analyzed. Statistical data processing was performed by means of MedStat software package. Results. The obtained results revealed that benign proliferative pathology of endometrium is one of the most frequent gynaecological malignancies among female patients of reproductive age accounting for 52.2 % cases. Endometrial polyps were found to be accompanied by morphological peculiarities indicating chronic inflammatory process in endometrium in 56.5% cases (р<0.05 in comparison with endometrial hyperplasia in 38.2% cases, proving the presence of long-term inflammation in endometrial tissue and its trigger role in the development of the proliferative processes. Among patients with chronic salpingo-oophoritis, infertility was revealed in almost half of cases (44.5% of patients with endometrial polyps, 40.5% of patients with endometrial hyperplasia and 48.3% of women with combined proliferative pathology of endometrium clinically confirming the data of morphological research. Peculiar signs of proliferative processes in genitals were determined, namely coexistence of uterine and endometrial pathology: endometrial hyperplasia was found in 40.4% of patients with uterine leiomyoma and 30.3% of patients with adenomyosis. The same combinations were peculiar for patients with endometrial polyps: endometrial hyperplasia was found in 30.1% of patients with uterine leiomyoma and 36.3% of patients with adenomyosis. Menstrual disorders were revealed in every third woman with endometrial hyperplasia (30.3% and co-existent polyposis (30.2%.

    To the authors' knowledge, there have been few studies of the psychologic distress after disclosure of genetic test results for hereditary nonpolyposis colorectal carcinoma (HNPCC). The objectives of this study were to identify the prevalence rates and predictors of psychologic distress and to evaluate the feelings of guilt after disclosure of the test results in Japanese probands and unaffected relatives. Probands and unaffected relatives were interviewed immediately after the first genetic counseling session for HNPCC and again 1 month after disclosure of the genetic test results. The prevalence of major and minor depression, acute stress disorder (ASD), posttraumatic stress disorder (PTSD), and posttraumatic stress symptoms (PTSS) were assessed using the Structured Clinical Interview based on the Diagnostic and Statistical Manual of Mental Disorders, 3rd edition revised (DSM-III-R) or the DSM-IV; feelings of guilt were investigated using a numeric scale and a semistructured interview. Among 47 participants who completed the baseline interview, 42 participants (89%) completed the 1-month follow-up interview. Although none of the participants met the criteria for major depression, ASD, or PTSD at the follow-up interview, 3 of 42 participants (7%) met the criteria for minor depression and 2 participants (5%) had PTSS. The only predictor of psychologic distress found was the presence of a history of major or minor depression (odds ratio, 19.41; 95% confidence interval, 1.42-264.95; P depression and PTSS.

    Objective: To determine the influence of peripheral blood hemoglobin concentration on the radiotherapy result of nasopharyngeal carcinoma (NPC). Methods: From January 1989 to December 1998, 304 patients with pathologically confirmed NPC received radical radiation. There were 209 males and 95 females. The ages ranged from 16 to 77 years with a median of 42. All patients were irradiated by 60 Co or 6 MV external beam with a total dose of 64 - 76 Gy for the primary tumor and 46 - 77 Gy for the cervical lymph nodes. The peripheral blood hemoglobin concentration for all patients was measured before, during and after radiotherapy. These patients were divided into three groups according to the peripheral blood hemoglobin concentration before radiotherapy: anemia ( 160 g/L), and into two groups according to the change in the peripheral blood hemoglobin concentration during radiotherapy as increased and decreased groups. Results: All patients were followed with a follow-up rate of 90.5%. The peripheral blood hemoglobin concentration had a significant effect on the survival of NPC patients. Its decrease or increase during radiotherapy affected the survival and local control rates of NPC patients. Conclusions: The change of peripheral hemoglobin concentration affecting the oxygen content in the blood, can influence the local control and survival rates of NPC patients. Increase results in higher survival

    Abstract To evaluate the relationship between endometrial thickness during fresh in vitro fertilization (IVF) cycles and the clinical outcomes of subsequent frozen embryo transfer (FET) cycles. FET cycles using at least one morphological good-quality blastocyst conducted between 2012 and 2013 at a university-based reproductive center were reviewed retrospectively. Endometrial ultrasonographic characteristics were recorded both on the oocyte retrieval day and on the day of progesterone supplementation in FET cycles. Clinical pregnancy rate, spontaneous abortion rate, and live birth rate were analyzed. One thousand five hundred twelve FET cycles was included. The results showed that significant difference in endometrial thickness on day of oocyte retrieval (P = .03) was observed between the live birth group (n = 844) and no live birth group (n = 668), while no significant difference in FET endometrial thickness was found (P = .261) between the live birth group and no live birth group. For endometrial thickness on oocyte retrieval day, clinical pregnancy rate ranged from 50.0% among patients with an endometrial thickness of ≤6 mm to 84.2% among patients with an endometrial thickness of >16 mm, with live birth rate from 33.3% to 63.2%. Multiple logistic regression analysis of factors related to live birth indicated endometrial thickness on oocyte retrieval day was associated with improved live birth rate (OR was 1.069, 95% CI: 1.011–1.130, P = .019), while FET endometrial thickness did not contribute significantly to pregnancy outcomes following FET cycles. The ROC curves revealed the cut-off points of endometrial thickness on oocyte retrieval day was 8.75 mm for live birth. Endometrial thickness during fresh IVF cycles was a better predictor of endometrial receptivity in subsequent FET cycles than FET cycle endometrial thickness. For those females with thin endometrium in fresh cycles, additional estradiol stimulation might be helpful for

    To evaluate the long-term follow-up results of percutaneous ethanol injection (PEI) for the treatment of hepatocellular carcinoma (HCC) in Korea. Sixty-eight nodular HCCs initially detected in 64 patients, were subjected to US-guided PEI as a first-line treatment. Long-term survival rates, local tumor progression rates, and complications were evaluated, as were the influences of tumor size and Child-Pugh class on these variables. No major complications occurred. The overall survival rates of the 64 patients at three and five years were 71% and 39%, and their cancer-free survival rates were 22% and 15%, respectively. The overall survival rate of patients with a small HCC (≤ 2 cm) was significantly higher (p = 0.014) than that of patients with a medium-sized HCC (≤ 2 cm). The overall survival rate of patients with Child- Pugh class A was significantly higher (p = 0.049) than that of patients with Child- Pugh class B. Of 59 cases with no residual tumor, local tumor progression was observed in ablation zones in 18, and this was not found to be significantly influenced by tumor size or Child-Pugh class. The results of our investigation of the long-term survival rates of PEI in HCC patients in Korea (a hepatitis B virus-endemic area) were consistent with those reported previously in hepatitis C endemic areas. Patients with a smaller tumor or a better liver function exhibited superior survival rates

    The prognosis of locally advanced lung cancer is reportedly poor in all histologic types. In non-small cell lung cancer, radiation therapy alone results in disappointing long-term survival. Three recent randomized trials, however, have shown a limited but significant improvement of survival with induction chemotherapy, though local control remained poor in these studies as well as in small-cell lung cancer treated with chemotherapy and late radiotherapy. Tow randomized trials focusing on small-cell lung cancer have recently shown significant benefit due to the combination of early concurrent mediastinal irradiation and chemotherapy, with major improvement in local control and a more than 40% 2-year survival rate. The concept of concurrent chemoradiotherapy has also been studied in non-small cell carcinoma with several pilot studies leading to both encouraging results and improved survival rate (up to 40% at 2 years). Ongoing phase III trials are comparing sequential versus concurrent chemoradiotherapy and will define the role of radical surgery after chemoradiotherapy in locally advanced non-small cell lung cancer.

    584 patients with carcinoma of the larynx treated with surgery of the larynx and bilateral functional neck dissection, between 1980 and 1989, were reviewed. 127 of them had histopathologically proven metastases to the lymph nodes. Pathologic stating of cervical metastases was as followed: pN1 - 24.5%, pN2a - 10.2%, pN2b - 26%, pN2c - 29.1%, pN3 - 10.2%. Of the 127 patients 89% were treated by surgery and postoperative radiation, 20% had surgery alone, that means radical or conservative neck dissection. In the group with combined treatment the results were much better than in cases of surgery alone, in advanced cases (pN2c, pN3) - 43.2% and 10% 5-year survival rate respectively. In the group of less advanced changes in the neck the difference in survival rate in the group with and without radiotherapy was very small. The results indicate that postoperative radiotherapy has great effect on survival rate in advanced cases of cervical metastases. (author)

    Abnormal uterine bleeding (AUB) is the direct cause of a significant health care burden for women, their families, and society as a whole. Up to 30% of women will seek medical assistance for the problem during their reproductive years. To provide current evidence-based guidelines on the techniques and technologies used in endometrial ablation (EA), a minimally invasive technique for the management of AUB of benign origin. Members of the guideline committee were selected on the basis of individual expertise to represent a range of practical and academic experience in terms of both location in Canada and type of practice, as well as subspecialty expertise and general background in gynaecology. The committee reviewed all available evidence in the English medical literature, including published guidelines, and evaluated surgical and patient outcomes for the various EA techniques. Recommendations were established by consensus. Published literature was retrieved through searches of MEDLINE and The Cochrane Library in 2013 and 2014 using appropriate controlled vocabulary and key words (endometrial ablation, hysteroscopy, menorrhagia, heavy menstrual bleeding, AUB, hysterectomy). RESULTS were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies written in English from January 2000 to November 2014. Searches were updated on a regular basis and incorporated in the guideline to December 2014. Grey (unpublished) literature was identifies through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). This document reviews the evidence regarding the available techniques and technologies for EA

    Purpose: To assess outcome of patients with bilateral breast carcinoma treated with bilateral breast conserving surgery with radiation therapy (CS+RT) and to compare their outcome to (1) patients with unilateral disease treated with CS+RT and (2) patients of comparable stage treated with bilateral mastectomy. Methods and Materials: The charts of all patients with the diagnosis of breast cancer treated with CS+RT at our facilities prior to 1993 were reviewed to identify patients with bilateral disease. A total of 50 patients identified as having bilateral breast cancer conservatively treated(BCT) served as the index population. Out of the 50 patients, 23 presented with synchronous bilateral breast cancer and 27 presented with metachronous bilateral breast cancer. A group of 984 patients with unilateral breast cancer (UCT) treated with CS+RT during the same time interval served as the first control group. A second control group was comprised of 42 patients with early stage bilateral breast cancer presenting during the same time interval treated with bilateral mastectomy (BMAST). Patients who had locally advanced disease in either breast or those patients treated exclusively for lobular carcinoma in situ in either breast were excluded from the analysis. Of the 42 BMAST patients, 33 presented with synchronous disease and nine presented with metachronous disease. Local-regional relapse rates were calculated from the date of treatment of each breast. Overall survival and distant relapse rates were calculated from the date of treatment of the second breast cancer diagnosed. Survival curves were calculated via the life table method and statistical comparisons between curves were performed using the log rank statistic. Chi square analysis was used to detect differences between categorical variables. Results: As of December 1995, the median follow-up of the bilateral conservatively treated patient population was 9.4 years. No statistically significant differences were noted

    Objective: To summarize the outcome of nasopharyngeal carcinoma (NPC) treated by helical tomotherapy in the Chinese PLA general hospital. Methods: Between September 2007 and August 2010, 121 newly diagnosed NPC patients were treated by radiotherapy with Tomotherapy system, with (n =90) or without (n = 31) concurrent chemotherapy or molecular target therapy. The prescription dose was 70 - 74 Gy/33f to primary tumor and positive lymph node planning target volume, 60.0 - 62.7 Gy/33f to high risk planning target volume, and 52 -56 Gy/33f to low risk planning target volume. Acute side-effects were evaluated with RTOG/EORTC criteria. Results: The remission rate of primary lesion and positive lymph nodes was 95.0% and 99.0%, respectively. The follow-up rate was 100%. The number of patients with 1, 2 and 3 years followed-up were 99, 49, and 7. The 1-, 2-and 3-year local relapse-free survival rates were 97.30%, 97.3% and 97.3%, respectively. The 1-, 2-and 3-year nodal relapse-free survival rates were 100%, 100% and 100%, respectively. The 1-, 2-and 3-year distant metastasis-free survival rates were 98.4%, 96.3% and 96.3%, respectively. The 1-, 2-and 3-year overall survival rates were 96.5%, 92.6% and 86.8%, respectively. Acute toxicities of skin, oral mucosa and xerostomia with grade 0, 1, 2 and 3 were 5.0%, 74.4%, 15.7% and 4.9%; 0.8%, 37.2%, 57.9% and 4.1%; 3.3%, 53.7%, 43.0% and 0%, respectively. Xerostomia restored with time, no grade 2 or more xerostomia was observed 1 year after radiation therapy. Concurrent chemotherapy significantly increased incidence of mucositis, esophagitis and tracheitis. Conclusion: Helical tomotherapy is efficient, secure and effective modality for the treatment of nasopharyngeal carcinoma. (authors)

    Background: Nasopharyngeal Carcinoma (NPC) is a common malignant neoplasm of the head and neck that occurs most commonly in people in the South Eastern Asia but its condition in Iran is not much clear. Objective: In this retrospective study, we evaluated the treatment characteristics determining the outcome in patients with NPC. Patients and Methods: In this retrospective study, we reviewed the records of one hundred and seven patients with biopsy proven diagnosis of NPC who were referred to the radiation oncology department, Nemazee Hospital, Shiraz University of Medical Sciences, Iran, during the time period from January 1985 to December 2000. Eighty five patients (79.4%) received 60-70 Gy radiation (1.82 Gy/fraction, one fraction per day, and 5 fractions per week). Sixty-two patients (57.5%) received radiotherapy combined with adjuvant chemotherapy which consisted of cisplatin and 5-fluorouracil. Eighty-six patients (80.4%) had WHO II-III histopathologic diagnosis. According to the AlCC 1997 staging system, 4 (3.6%), 3 (2.7%), 33 (30.8%) and 67 (62%) patients were in stages I, II, III and IV, respectively. Results: With a median follow-up of 12 months, the 2-year overall and disease-free survival rates were 35% and 21%, respectively. According to the multivariate analysis for overall survival, patients under 40 years had a better prognosis (p=0.041). Node stage and stage of disease were significant prognostic factors (p=0.0001. On multivariate analysis for disease-free survival, age and node stage were significant prognostic factors. The patients who received more than 60 Gy radiation had a better prognosis (p=0.02), however; sequential adjuvant chemotherapy had no impact on survival and response (p=0.6). Conclusion: Our experience confirmed earlier reports showing poor outcomes for locoregionally advanced nasopharyngeal carcinomas. This study failed to demonstrate improvement in the outcome regarding overall and disease-free survival by adding sequential

    Background: First clinical data on a new intracavitary afterloading boost method for anal canal carcinoma is reported. Patients and Methods: 20 consecutive patients (T1 5%, T2 70%, T3 20%, T4 5%; N0 75%, N1 10%, N2 15%; all M0) treated with external beam pelvic radiotherapy (median dose 56 Gy, range 46-64 Gy), simultaneous 5-FU and mitomycin (in 75%) and an intracavitary afterloading boost (one or two fractions of 5 Gy at 5 mm depth) were analyzed after a mean ±SD follow-up for living patients of 4.4±2.1 years. Quality of life (QoL) and anorectal manometry parameters were assessed in ten colostomy-free survivors. Results: Overall, recurrence-free and colostomy-free survival at 5 years were 84%, 79% and 69%, respectively. No death was tumorrelated. The only local failure was successfully salvaged by local excision. All three colostomies were performed for toxicity. Resting pressure and maximum squeeze pressure of the anal sphincter were reduced by 51% and 71%, as compared with control subjects, but quality of life was similar compared to healthy volunteers. Conclusion: the described regimen is highly effective but associated with increased toxicity. (orig.) [de

    The purpose of this report is to record the results of a treatment protocol for patients with carcinoma of the esophagus. In May, 1980, the authors initiated a program of chemoradiation therapy preliminary to resection in patients in whom the protocol was applicable. The chemotherapy consisted of mitomycin-C, 10 mg as a bolus intravenous injection on day 1, and 5-fluorouracil, 1,000 mg per square meter of body surface area given intravenously on each of days 1 through 4. The radiation therapy consisted of 3,000 rads in three weeks using cobalt 60 or 6 MeV or greater, with ports to cover the tumor and mediastinum. Among the patients treated according to the protocol, the operability rate was increased. The resectability rate remained about the same as in our previous experience. The operative mortality was lessened appreciably. The percentage of resected specimens of the esophagus showing residual tumor decreased. However, the absence of any residual tumor in the surgical specimen has not conferred any improved chance of long-term survival to date

    BACKGROUND Cancer is a multifactorial disease and skin carcinomas are the most common type of cancer. Assessing quality of life and self-esteem outcomes in skin cancer patients is important because these are indicators of the results of the treatment, translating how patients face their lives and their personal relationships. OBJECTIVE To assess the late impact of the surgical treatment of head and/or neck skin carcinomas on quality of life and self-esteem of the patients. METHODS Fifty patients with head or neck skin carcinomas were enrolled. Their age ranged between 30 and 75 years, 27 were men and 23 were women. Patients were assessed with regard to quality of life and self-esteem, preoperatively and five years postoperatively. Validated instruments were used: the MOS 36-item Short-form Health Survey (SF-36) and the Rosenberg Self-esteem/EPM-UNIFESP Scale. The Wilcoxon signed-rank test was used for the statistical analysis. RESULTS Twenty-two patients completed the five-year follow-up, 54.5% women and 45.5% men. Compared to the preoperative assessment, patients had an improvement in mental health (p=0.011) and in self-esteem (p=0.002). There was no statistical difference with regard to the other domains of the SF-36. CONCLUSION Patients submitted to surgical treatment of skin carcinoma improved mental health and self-esteem in the late postsurgical testing. PMID:25054746

    Women with Lynch syndrome have a 40–60% lifetime risk for developing endometrial cancer, a cancer associated with estrogen imbalance. The molecular basis for endometrial-specific tumorigenesis is unclear. Progestins inhibit estrogen-driven proliferation, and epidemiologic studies have demonstrated that progestin-containing oral contraceptives (OCP) reduce the risk of endometrial cancer by 50% in women at general population risk. It is unknown if they are effective in women with Lynch syndrome. Asymptomatic women age 25–50 with Lynch syndrome were randomized to receive the progestin compounds depo-Provera (depoMPA) or OCP for three months. An endometrial biopsy and transvaginal ultrasound were performed before and after treatment. Endometrial proliferation was evaluated as the primary endpoint. Histology and a panel of surrogate endpoint biomarkers were evaluated for each endometrial biopsy as secondary endpoints. A total of 51 women were enrolled, and 46 completed treatment. Two of the 51 women had complex hyperplasia with atypia at the baseline endometrial biopsy and were excluded from the study. Overall, both depoMPA and OCP induced a dramatic decrease in endometrial epithelial proliferation and microscopic changes in the endometrium characteristic of progestin action. Transvaginal ultrasound measurement of endometrial stripe was not a useful measure of endometrial response or baseline hyperplasia. These results demonstrate that women with Lynch syndrome do show an endometrial response to short term exogenous progestins, suggesting that OCP and depoMPA may be reasonable chemopreventive agents in this high-risk patient population.

    Purpose: To report preliminary results of a very accelerated radiation therapy Phase I/II trial in locally advanced head and squamous cell carcinomas (HNSCC). Methods and Materials: Between 01/92 and 06/93, 35 patients with an unresectable HNSCC were entered in this study. Thirty-two (91%) had Stage IV, and 3 had Stage III disease. The mean nodal diameter, in patients with clinically involved nodes (83%), was 6.3 cm. The median Karnovsky performance status was 70. The treatment consisted of a twice daily schedule (BID) giving 62 Gy in 20 days. Results: In all cases, confluent mucositis was observed, which started about day 15 and resolved within 6 to 10 weeks. Eighty percent of patients had enteral nutritional support. The nasogastric tube or gastrostomy was maintained in these patients for a mean duration of 51.8 days. Eighteen patients (53%) were hospitalized during the course of treatment due to a poor medical status or because they lived far from the center (mean 25 days). Nineteen patients (56%) (some of whom were initially in-patients) were hospitalized posttreatment for toxicity (mean 13 days). Five patients (15%) were never hospitalized. During the follow-up period, 12 local and/or regional failures were observed. The actuarial 18-month loco-regional control rate was 59% (95% confidence interval, 45-73%). Conclusions: The dramatic shortening of radiation therapy compared to conventional schedules in our series of very advanced HNSCC resulted in: (a) severe acute mucosal toxicity, which was manageable but required intensive nutritional support in all cases; and (b) high loco-regional response rates, strongly suggesting that the time factor is likely to be critical for tumor control in this type of cancer.

    Purpose: To analyze the results of radical radiotherapy by electron beams for squamous cell carcinoma (SCC) of the eyelid and to find the possible prognostic factors. Materials and Methods: Records of 38 patients with histologically confirmed SCC of the eyelid who underwent electron beam radiation therapy between 1964 and 2010 in our institution were retrospectively reviewed. Median tumor size was 15 mm (range, 3–40 mm). T stage was T1 in three, T2a in six, T2b in 14, and T3a in 15 patients. Four patients had nodal metastasis. Of the 38 patients, 14 had relapsed disease after prior treatment. Median radiation dose was 60.0 Gy (range, 45.0–70.4 Gy). Median follow-up was 72.5 months (range, 2.0–369 months). Results: 5-year local relapse-free, nodal relapse-free, distant metastasis-free and relapse-free rates for all patients were 71.8%, 77.5%, 90.6% and 58.0%, respectively. In seven patients, lymph node metastases occurred in 11 faciocervical regions. The 5-year overall survival was 79.5%. T stage and radiation dose expressed in EQD 2 Gy tended to have impacts on local control. Relapsed patients showed unfavorable local relapse-free rate, however this was without statistical significance. Of the 14 patients who died, 12 succumbed to concurrent diseases. Grade 3 or greater severe late morbidities (CTCAE ver4.0) were observed in nine patients. Due to the morbidities, two patients lost their vision. Conclusion: Radical radiotherapy for SCC of the eyelid yielded good results and could be a treatment option. Whether radiation-dose escalation could improve local control in advanced T stages and relapsed patients needs further study

    Selective progesterone receptor modulators are a class of drugs with progesterone antagonist activity that may confer therapeutic benefit for reproductive disorders in premenopausal women. Endometrial structure, which is dynamically controlled by circulating sex hormones, is likely to be perturbed by progesterone receptor modulators through their progesterone antagonist properties. We examined endometrial histology in 58 premenopausal women treated with the progesterone receptor modulator CDB-4124 (also known as Proellex) for endometriosis or uterine leiomyomata in two clinical trials. Endometrial biopsies obtained after 3 or 6 months with doses of 12.5, 25, or 50 mg daily oral CDB-4124 were reviewed independently by three pathologists. Consensus diagnoses using the World Health Organization hyperplasia scoring system, comments on specific histologic features, and clinical annotation were collected and analyzed. The majority of the endometrial biopsies (103 of 174 biopsies) contained histologic changes that are not seen during normal menstrual cycles. The histology of CDB-4124-treated patients was generally inactive or atrophic, and less frequently, proliferative or secretory, superimposed upon which were novel changes including formation of cystically dilated glands, and secretory changes coexisting with mitoses and apoptotic bodies. With increasing treatment dose and duration, the cysts became predominant and their lining inactive or atrophic. Cystic glands in the CDB-4124-treated subjects correlated with increased endometrial thickness by ultrasound. None of the CDB-4124-treated patients developed endometrial carcinoma or hyperplasia while on therapy. CDB-4124 therapy for 3-6 months produces histologic changes that are sufficiently novel that they might easily be misinterpreted by pathologists, particularly as disordered proliferative or hyperplastic endometrium. Knowledge of the constellation of endometrial changes associated with this agent and other

    PURPOSE: Carcinoma of the endometrium is the most common gynecological malignancy in the U.S. As the treatment for endometrial cancer has evolved, FIGO has modified the staging three times over the past 25 years This course will review current staging, prognostic factors, treatment options, rationale and management strategies for patients with endometrial carcinoma. The data regarding local control and survival, and the ongoing clinical trials and controversies will be discussed in depth. MATERIALS AND METHODS: Despite the continued controversy regarding the true contribution of extensive surgical staging, the standard treatment for operable patients is total abdominal hysterectomy-bilateral salpingoopherectomy with regional lymph node staging. Various combinations of surgery and radiation have been used in the past, but the precise role of radiation as an adjuvant treatment is not well defined due to lack of well conducted randomized trials. With better knowledge and understanding of the natural history of the disease and significance of prognostic factors, three different risk groups have been identified; low risk, intermediate risk, high risk. Postoperative radiation has been shown to decrease local failures and improve survival in the majority of the intermediate risk group and high risk group of patients. Considerable experience has been accumulated in the use of High Dose Rate fractionated intravaginal treatment, and it probably has a very broad application in optimizing local control, with minimal morbidity. A stage-specific treatment algorithm, including critical pathways for the management of early and advanced endometrial cancer will be presented. RESULTS: As is evident from the long-term published data, the results of combined surgery and radiation treatment have been very satisfactory with minimal complications. CONCLUSION: A thorough assessment of the clinical and surgicopatho-logic prognostic parameters, in the context of the natural history of the

    Women with Turner's syndrome exhibit anovulation, and the majority do not spontaneously menstruate. We present an unusual case of endometrial adenocarcinoma developing in a Turner's syndrome patient who was exhibiting spontaneous menstruation while not receiving regular hormone therapy. The patient's karyotype from blood lymphocytes was a mosaic of 45,XO/ 46,XX. Menarche and sexual development were normal. Her menstrual cycle had been regular for one year, but then became noticeably irregular. At age 26 she was referred to our hospital after bleeding for almost 1 year. An endometrial adenocarcinoma was detected during performance of diagnostic endometrial curettage. A total abdominal hysterectomy with bilateral salpingo-oophorectomy and pelvic lymphadenectomy was conducted. The final histological diagnosis was endometrial adenocarcinoma, Grade 1, pT1a N0 M0. Fluorescence in situ hybridization analysis of the right and left ovaries revealed a mosaic karyotype of 45,XO/ CONCLUSION: Previous reports regarding Turner's syndrome detected spontaneous menstruation in only 16% of patients; however, spontaneous menstruation was observed in 8 of 10 (80%) Turner's syndrome cases that developed endometrial carcinoma without receiving regular hormone therapy (p < 0.0001). Hormone therapy may be indicated for an irregular menstrual cycle in Turner's syndrome patients.

  10. Stathmin protein level, a potential predictive marker for taxane treatment response in endometrial cancer.

    Directory of Open Access Journals (Sweden)

    Henrica M J Werner

    Full Text Available Stathmin is a prognostic marker in many cancers, including endometrial cancer. Preclinical studies, predominantly in breast cancer, have suggested that stathmin may additionally be a predictive marker for response to paclitaxel. We first evaluated the response to paclitaxel in endometrial cancer cell lines before and after stathmin knock-down. Subsequently we investigated the clinical response to paclitaxel containing chemotherapy in metastatic endometrial cancer in relation to stathmin protein level in tumors. Stathmin level was also determined in metastatic lesions, analyzing changes in biomarker status on disease progression. Knock-down of stathmin improved sensitivity to paclitaxel in endometrial carcinoma cell lines with both naturally higher and lower sensitivity to paclitaxel. In clinical samples, high stathmin level was demonstrated to be associated with poor response to paclitaxel containing chemotherapy and to reduced disease specific survival only in patients treated with such combination. Stathmin level increased significantly from primary to metastatic lesions. This study suggests, supported by both preclinical and clinical data, that stathmin could be a predictive biomarker for response to paclitaxel treatment in endometrial cancer. Re-assessment of stathmin level in metastatic lesions prior to treatment start may be relevant. Also, validation in a randomized clinical trial will be important.

    Background: Signal transducer and activator of transcription-3 (STAT-3) is a downstream component of the Epidermal Growth Factor Receptor (EGFr) signaling process that may facilitate the resistance of tumor cells to conventional cancer treatments. Studies were performed to determine if inhibition of this downstream protein produces radiosensitization. Methods/Results: A431 cells (human squamous cell carcinoma cells with EGFr overexpression) were found to be sensitized to radiation after treatment with STAT-3 small interfering RNA (siRNA). Therefore, a short hairpin RNA (shRNA) against STAT-3 was designed and cloned into a pBABE vector system modified for shRNA expression. Following transfection, clone 2.1 was selected for further study as it showed a dramatic reduction of STAT-3 protein (and mRNA) when compared to A431 parental cells or a negative control shRNA cell line (transfected with STAT-3 shRNA with 2 base pairs mutated). A431 2.1 showed doubling times of 25-31 h as compared to 18-24 h for the parental cell line. The A431 shRNA knockdown STAT-3 cells A431 were more sensitive to radiation than A431 parental or negative STAT-3 control cells. Conclusion: A431 cells stably transfected with shRNA against STAT-3 resulted in enhanced radiosensitivity. Further work will be necessary to determine whether the inhibition of STAT-3 phosphorylation is a necessary step for the radiosensitization that is induced by the inhibition of EGFr.

    Objective: The inhibition of epidermal growth factor receptor (EGFr) with the monoclonal antibody cetuximab reduces cell proliferation and survival which correlates with increased DNA damage. Since the signal transducer and activator of transcription-3 (STAT-3) is involved in the EGFr-induced signaling pathway, we hypothesized that depletion of STAT-3 may augment cetuximab-induced processes in human head and neck cancer cells. Materials and methods: Human head and neck squamous carcinoma cells (UM-SCC-5) were transfected with short hairpin RNA (shRNA) against STAT-3 (STAT3-2.4 and 2.9 cells). A mutated form of this shRNA was transfected for a control (NEG4.17 cells). Radiosensitivity was assessed by a standard colony formation assay. Proliferation was assessed by daily cell counts following treatment and apoptosis was assessed by an annexin V-FITC assay. The alkaline comet assay was used to assess DNA damage. Results: The STAT-3 knockdown cells (STAT3-2.4 and STAT3-2.9 cells) demonstrated enhanced radiosensitivity compared to control NEG4.17 cells, which correlated with increased apoptosis. Also, the STAT-3 knockdown cells demonstrated decreased proliferation with cetuximab treatments compared to control cells (NEG4.17). The increased cetuximab sensitivity of the STAT-3 knockdown cells correlated with increased apoptosis and DNA damage compared to control cells (NEG4.17). Conclusion: These studies revealed that the greater anti-proliferative effects and increased cytotoxicity of cetuximab in the STAT3-2.4 and STAT3-2.9 cells compared to control NEG4.17 cells, may be a result of STAT3-mediated effects on cellular apoptosis and DNA damage.

    Purpose: To assess the dosimetric and clinical results of three-dimensional conformal radiotherapy (3D CRT) for locally recurrent nasopharyngeal carcinoma (NPC). Methods: A total of 86 patients with locally recurrent NPC were retreated with 3D CRT. The median prescribed dose was 68 Gy with 2 Gy per fractionation. Dosimetric quality was evaluated with dose distribution in planning target volume (PTV) and specified organs at risk (OAR), dose conformity index (CI) and dose homogeneity index (HI). The actuarial rate of local failure-free (LFF), overall survival (OS) and major late toxicities (MLT) were estimated with Kaplan-Meier method. Multivariate analysis for prognosis was performed using the Cox regression proportional hazards model. Results: The mean dose to PTV averaged 66.8 Gy, and the dose to specified OAR was acceptable. The average value of CI and HI was 0.59 and 9.1%. The 5-year actuarial rate of LFF and OS was 71 and 40%, respectively. The 5-year actuarial incidence of MLT≥Grade 3 and ≥Grade 4 were 100 and 49%, respectively. The major prognostic factors were T stage and the size of gross tumor volume (GTV). Advanced T stage and large GTV volume were associated with poor LFF and OS and high risk of MLT. Conclusion: The dosimetric quality of 3D CRT for locally recurrent NPC is generally excellent. A relatively high local control was achieved with this technique. However, the incidence of late toxicities were not found to decrease as originally expected. Early diagnosis of the recurrence and reasonable definition of the target volume are crucial to achieve a better outcome

    Although curcumin shows anti-proliferative and anti-inflammatory activities in various cancers, the effect of curcumin on cellular migration in endometrial adenocarcinoma cells remains to be understood. The current investigation was aimed to explore the anti-proliferative and anti-migratory effects of curcumin and its mechanism of action in endometrial cancer cells. Our in-vitro and in-vivo experimental studies showed that curcumin inhibited the proliferation of endometrial cancer cells and suppressed the tumor growth in Ishikawa xenograft mouse model. Curcumin induced ROS-mediated apoptosis in endometrial cancer cells. Curcumin suppressed the migration rate of Ishikawa and Hec-1B cells as analyzed by scratch wound assay. In transwell migration studies, knock down of Slit-2 reversed the anti-migratory effect of curcumin in these cell lines. Curcumin significantly up-regulated the expression of Slit-2 in Ishikawa, Hec-1B and primary endometrial cancer cells while it down-regulated the expression of stromal cell-derived factor-1 (SDF-1) and CXCR4 which in turn, suppressed the expression of matrix metallopeptidases (MMP) 2 and 9, thus attenuating the migration of endometrial cancer cells. In summary, we have demonstrated that curcumin has inhibitory effect on cellular migration via Slit-2 mediated down-regulation of CXCR4, SDF-1, and MMP2/MMP9 in endometrial carcinoma cells. These findings helped explore the role of Slit-2 in endometrial cancer cells. Copyright © 2017 Elsevier Inc. All rights reserved.

    MUTYH-associated polyposis (MAP) is an autosomal recessive condition predisposing to colorectal cancer, caused by constitutional biallelic mutations in the base excision repair (BER) gene MUTYH. Colorectal tumours from MAP patients display an excess of somatic G>T mutations in the APC and KRAS genes due to defective BER function. To date, few extracolonic manifestations have been observed in MAP patients, and the clinical spectrum of this condition is not yet fully established. Recently, one patient with a diagnosis of endometrial cancer and biallelic MUTYH mutations has been described. We here report on two additional unrelated MAP patients with biallelic MUTYH germline mutations who developed endometrioid endometrial carcinoma. The endometrial tumours were evaluated for PTEN, PIK3CA, KRAS, BRAF and CTNNB1 mutations. A G>T transversion at codon 12 of the KRAS gene was observed in one tumour. A single 1bp frameshift deletion of PTEN was observed in the same sample. Overall, these findings suggest that endometrial carcinoma is a phenotypic manifestations of MAP and that inefficient repair of oxidative damage can be involved in its pathogenesis.

    We previously reported frequent loss of TESTIN in human endometrial carcinoma, which significantly suppressed tumor proliferation and invasion. Herein, we further explored the mechanisms underlying TESTIN loss and its roles in the epithelial-mesenchymal transition (EMT, a key step for tumor spreading). Methylation-specific PCR was performed to investigate the promoter status of TESTIN in a panel of endometrial cancer and normal endometrium tissues. The expression of TESTIN mRNA was determined by real-time PCR. Up- and down-regulation of TESTIN were achieved by transient transfection with pcDNA3.1-TESTIN and shRNA-TESTIN plasmids, respectively. The EMT alterations were observed under the optical microscope and EMT-related markers were detected by real-time PCR and western blot. Compared to the control (3.6%), TESTIN was hypermethylated in 43.7% endometrial cancer tissues (p < 0.001). Moreover, TESTIN hypermethylation was significantly correlated with advanced tumor stage, deep myometrial invasion and lymphatic node metastasis. In vitro, the demethylating agent dramatically restored the expression of TESTIN. In addition, up-regulation of TESTIN significantly suppressed the EMT procedure; whereas down-regulation of TESTIN enhanced EMT. In conclusion, we demonstrated that loss of TESTIN was mainly caused by hypermethylation, which might be a potent prognostic marker. Furthermore, we proved that TESTIN significantly suppressed the EMT procedure, proposing restoration of TESTIN to be a novel therapeutic strategy for endometrial carcinoma. © 2015 APMIS.

    2016-01-01

    OBJECTIVE: Non-steroidal anti-inflammatory drug (NSAID) use has been linked to a reduction in the risk of several cancer types. For endometrial cancer, however, results have been inconsistent. To summarize the available evidence on the risk of endometrial cancer associated with use of aspirin...... a random effects model. RESULTS: Six case-control and seven cohort studies were found eligible for our meta-analysis. We observed risk reductions in endometrial cancer associated with regular use of aspirin (case-control: 11%, cohort: 8%) and NA-NSAIDs (case-control: 9%, cohort: 6%), compared to non...

    Purpose: The purpose of this work was to examine outcomes in patients with T4 nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiation therapy (IMRT). Methods and materials: Between 2007 and 2010, 154 patients with nonmetastatic T4 NPC were treated with IMRT to a total dose of 70 Gy in 33-35 fractions. In addition, 97 % of patients received concurrent platinum-based chemotherapy. The median follow-up time was 52.8 months. Results: The rates of 5-year actuarial locoregional control, distant metastasis-free survival, progression free-survival, and overall survival (OS) were 81.2, 72.2, 61.9, and 78.1 %, respectively. A total of 27 patients had locoregional recurrence: 85.2 % in-field failures, 11.1 % marginal failures, and 3.7 % out-of-field failures. Fourteen patients with locoregional recurrence received aggressive treatments, including nasopharyngectomy, neck dissection, or re-irradiation, and the 5-year OS rate tended to be better (61.9 %) compared to those receiving conservative treatment (32.0 %, p = 0.051). In patients treated with 1 course of radiotherapy, grade {>=} 3 toxicities of ototoxicity, neck fibrosis, xerostomia, epistaxis, and radiographic temporal lobe necrosis occurred in 18.2, 9.8, 6.3, 2.1, and 5.6 % of patients, respectively. Increased ototoxicity, osteonecrosis, severe nasal bleeding, and temporal necrosis were observed in patients treated by re-irradiation. Conclusion: IMRT offers good locoregional control in patients with T4 NPC. For patients with locoregional recurrence after definitive radiotherapy, aggressive local treatment may be considered for a better outcome. (orig.)

    To present preliminary results of intensity-modulated radiotherapy (IMRT) using the simultaneous modulated accelerated radiation therapy (SMART) boost technique in patients with nasopharyngeal carcinoma (NPC). Twenty patients who underwent IMRT for non-metastatic NPC at the Asan Medical Center between September 2001 and December 2003 were prospectively evaluated. IMRT was delivered using the 'step and shoot' SMART technique at prescribed doses of 72 Gy (2.4 Gy/day) to the gross tumor volume (GTV), 60 Gy (2 Gy/day) to the clinical target volume (CTV) and metastatic nodal station, and 46 Gy (2 Gy/day) to the clinically negative neck region. Eighteen patients also received concurrent chemotherapy using cisplatin once per week. The median follow-up period was 27 months. Nineteen patients completed the treatment without interruption; the remaining patient interrupted treatment for 2 weeks owing to severe pharyngitis and malnutrition. Five patients (25%) had RTOG grade 3 mucositis, whereas nine (45%) had grade 3 pharyngitis. Seven patients (35%) lost more than 10% of their pretreatment weight, whereas 11 (55%) required intravenous fluids and/or tube feeding. There was no grade 3 or 4 chronic xerostomia. All patients showed complete response. Two patients had distant metastases and loco-regional recurrence, respectively. IMRT using the SMART boost technique allows parotid sparing, as shown clinically and by dosimetry, and may also be more effective biologically. A larger population of patients and a longer follow-up period are needed to evaluate ultimate tumor control and late toxicity.

    Ovarian carcinoma is the deadliest gynecological malignancy. Previous studies have suggested that the fallopian tube may be the primary site for high-grade serous carcinoma. In prophylactic salpingo-oophorectomies from women with hereditary high risk for ovarian cancer, precursors can be assessed prior to onset and studied as a model for serous cancer precursor lesions. Epidemiologic studies indicate that carcinogenesis may be a result of chronic fallopian tube injury. The aims of this study were to (1) to examine the incidence of serous tubal intraepithelial carcinoma (STIC) in relation to other clinical parameters and (2) to evaluate whether chronic fallopian tube injury was related to cancer development. This study enrolled 101 women, comprising the following three groups: hereditary (n = 60), sporadic serous cancer (n = 18; endometrial cancers were excluded), and control (n = 23). The cases were histologically examined and clinical risk factors were collected. The histological changes were compared between different patients and correlated to clinical risk factors. STICs were identified primarily on the fallopian tube fimbria. The incidence of STIC was 3 % in the hereditary patients. In sporadic serous cancer cases, 61 % were associated with STIC and tubal carcinoma (p STIC and invasive cancer were seen more often in the older patients than in the younger patients (p = 0.528). This small study, no correlation with chronic tubal injury or inflammation was identified.

    Purpose: To evaluate the efficacy of accelerated fractionated radiotherapy using the concomitant boost schedule for patients with squamous cell carcinoma of the base of tongue. Methods and Materials: Between September 1984 and July 1992, 54 patients with squamous carcinoma of the base of tongue were treated at The University of Texas M. D. Anderson Cancer Center using the concomitant boost schedule. The distribution of T and N stages was T1-4, T2-27, T3-22, and T4-1; N0-9, N1-11, N2-24, N3-7, and NX-3. American Joint Committee on Cancer (AJCC) stage groupings were II-6, III-14, and IV-34. Before radiation, nodal excision and neck dissection were done in 5 and 10 patients, respectively; 5 patients had neck dissections after radiotherapy. Standard on and off spinal cord fields were irradiated with 1.8 Gy fractions to 54 Gy given over 6 weeks. The boost was given concomitantly during the large field treatment as a second daily (1.5 Gy) fraction, with an interfraction interval of 4-6 h. The median dose to the primary tumor was 72 Gy (range, 66-74 Gy). The median treatment duration was 42 days (range, 39-48 days). Only three patients had treatment interrupted for more than one scheduled treatment day. Results: The 5-year actuarial overall survival and disease-specific survival rates were 59 and 65%, respectively, with a median follow-up of 41 months. The 5-year actuarial locoregional control rate was 76%. The actuarial local control rates achieved with radiotherapy at 5 years for T1, T2, and T3 primary tumors were 100%, 96%, and 67%, respectively; including surgical salvage, the local control rate of T3 primary tumors was 70%. Six patients had regional failures, which in three patients occurred in conjunction with primary tumor recurrence. Twenty-six patients with regional adenopathy were treated with radiation alone to full dose and had a complete clinical response in the neck; no planned neck dissections were performed in these patients. Only 2 of these 26 patients

    Background Endometrial cancer is a common cause of death in gynecological malignancies. Cisplatin is a clinically chemotherapeutic agent. However, drug-resistance is the primary cause of treatment failure. Objective Emodin is commonly used clinically to increase the sensitivity of chemotherapeutic agents, yet whether Emodin promotes the role of Cisplatin in the treatment of endometrial cancer has not been studied. Method CCK-8 kit was utilized to determine the growth of two endometrial cancer cell lines, Ishikawa and HEC-IB. The apoptosis level of Ishikawa and HEC-IB cells was detected by Annexin V / propidium iodide double-staining assay. ROS level was detected by DCFH-DA and NADPH oxidase expression. Expressions of drug-resistant genes were examined by real-time PCR and Western blotting. Results Emodin combined with Cisplatin reduced cell growth and increased the apoptosis of endometrial cancer cells. Co-treatment of Emodin and Cisplatin increased chemosensitivity by inhibiting the expression of drug-resistant genes through reducing the ROS levels in endometrial cancer cells. In an endometrial cancer xenograft murine model, the tumor size was reduced and animal survival time was increased by co-treatment of Emodin and Cisplatin. Conclusion This study demonstrates that Emodin enhances the chemosensitivity of Cisplatin on endometrial cancer by inhibiting ROS-mediated expression of drug-resistance genes.

  9. Factors Influencing the Recurrence Potential of Benign Endometrial Polyps after Hysteroscopic Polypectomy.

    Directory of Open Access Journals (Sweden)

    Jehn-Hsiahn Yang

    Full Text Available An endometrial polyp is a frequently encountered gynecologic disease with abnormal uterine bleeding and infertility being the two common presenting problems, and hysteroscopic polypectomy is an effective method to remove them. The postoperative polyp recurrence might result in reappearance of abnormal uterine bleeding or infertility, whereas factors influencing the postoperative recurrence potential have limited data.This case-series report included 168 premenopausal women who suffered from endometrial polyps and underwent hysteroscopic polypectomy. All of them were awaiting a future pregnancy. Office hysteroscopy was done before and after hysteroscopic polypectomy, in which preoperative hysteroscopy examined the number, type, and location of endometrial polyps, and postoperative hysteroscopy checked the polyp recurrence. Surgical indications, either infertility or the presentation of abnormal uterine bleeding, and follow-up duration were recorded.Seventy-three out of 168 (43% women had polyp recurrence after hysteroscopic polypectomy. Multivariate logistic regression analysis revealed that more endometrial polyps (P = 0.015 and longer duration of follow-up (P = 0.004 were significantly associated with an increased risk of postoperative polyp recurrence. The type of endometrial polyps was not correlated with polyp recurrence potential, whereas pedunculated type endometrial polyps were closely related to the presentation of abnormal uterine bleeding (P = 0.001.A higher number of endometrial polyps and longer follow-up duration are associated with a greater potential of polyp recurrence after hysteroscopic polypectomy.

    Full Text Available Introduction: By the early 21st century the most common cancer of female genitals in Poland was cervical cancer. Now endometrial cancer ranks first. The aim of this study was to analyse the incidence and mortality of endometrial and cervical cancer among women in the Lodz region. Material and methods: Data on the incidence and mortality of endometrial and cervical cancer among inhabitants of the Lodz region were obtained from the National Cancer Registry and Bulletin of Cancer Cases in the Lodz region. The analysis covered ten consecutive years beginning in 2001. Results : The number of new cases reported in 2010 exceeded that observed in 2001 by 181. The standardized incidence rate of endometrial cancer increased by 6.3, while the standardized incidence rate of cervical cancer decreased by 1.4. Conclusions : In the years 2001-2010, the incidence of endometrial cancer increased by 88.3% and that of cervical cancer decreased by 6.5% among inhabitants of the Lodz region. In the years 2001-2010, mortality of endometrial cancer increased by 24.5% and that of cervical cancer decreased by 12.6%. In 2010, the highest crude incidence rates in the Lodz region of both endometrial and cervical cancer at 39.1 were recorded in the district town of Piotrków.

  11. Glycogen Synthase Kinase 3β Inhibition as a Therapeutic Approach in the Treatment of Endometrial Cancer

    Directory of Open Access Journals (Sweden)

    2013-08-01

    Full Text Available Alternative strategies beyond current chemotherapy and radiation therapy regimens are needed in the treatment of advanced stage and recurrent endometrial cancers. There is considerable promise for biologic agents targeting the extracellular signal-regulated kinase (ERK pathway for treatment of these cancers. Many downstream substrates of the ERK signaling pathway, such as glycogen synthase kinase 3β (GSK3β, and their roles in endometrial carcinogenesis have not yet been investigated. In this study, we tested the importance of GSK3β inhibition in endometrial cancer cell lines and in vivo models. Inhibition of GSK3β by either lithium chloride (LiCl or specific GSK3β inhibitor VIII showed cytostatic and cytotoxic effects on multiple endometrial cancer cell lines, with little effect on the immortalized normal endometrial cell line. Flow cytometry and immunofluorescence revealed a G2/M cell cycle arrest in both type I (AN3CA, KLE, and RL952 and type II (ARK1 endometrial cancer cell lines. In addition, LiCl pre-treatment sensitized AN3CA cells to the chemotherapy agent paclitaxel. Administration of LiCl to AN3CA tumor-bearing mice resulted in partial or complete regression of some tumors. Thus, GSK3β activity is associated with endometrial cancer tumorigenesis and its pharmacologic inhibition reduces cell proliferation and tumor growth.

    Bacterial cells in the human body account for 1-3% of total body weight and are at least equal in number to human cells. Recent research has focused on understanding how the different bacterial communities in the body (eg, gut, respiratory, skin, and vaginal microbiomes) predispose to health and disease. The microbiota of the reproductive tract has been inferred from the vaginal bacterial communities, and the uterus has been classically considered a sterile cavity. However, while the vaginal microbiota has been investigated in depth, there is a paucity of consistent data regarding the existence of an endometrial microbiota and its possible impact in reproductive function. This study sought to test the existence of an endometrial microbiota that differs from that in the vagina, assess its hormonal regulation, and analyze the impact of the endometrial microbial community on reproductive outcome in infertile patients undergoing in vitro fertilization. To identify the existence of an endometrial microbiota, paired samples of endometrial fluid and vaginal aspirates were obtained simultaneously from 13 fertile women in prereceptive and receptive phases within the same menstrual cycle (total samples analyzed n = 52). To investigate the hormonal regulation of the endometrial microbiota during the acquisition of endometrial receptivity, endometrial fluid was collected at prereceptive and receptive phases within the same cycle from 22 fertile women (n = 44). Finally, the reproductive impact of an altered endometrial microbiota in endometrial fluid was assessed by implantation, ongoing pregnancy, and live birth rates in 35 infertile patients undergoing in vitro fertilization (total samples n = 41) with a receptive endometrium diagnosed using the endometrial receptivity array. Genomic DNA was obtained either from endometrial fluid or vaginal aspirate and sequenced by 454 pyrosequencing of the V3-V5 region of the 16S ribosomal RNA (rRNA) gene; the resulting sequences were

    Purpose: Three phase bone scan is an imaging technology in nuclear medicine, which composed of blood flow phase, blood pool phase and delayed phase and the last one is often performed in routine works in department of nuclear medicine. The purpose of this study is to evaluate the merit of three-phase bone scan.Methods: In this study, we chose 54 patients who were having an regional pain which caused by benign or malignant carcinoma that diagnosed by CT, X-ray, ECT, MRI or other examinations. The imaging were acquired simultaneously from both anterior and posterior views, after a bolus injection of 1110 MBq technetium-99m-labelled methylene diphosphonate (MDP), blood phase contains 20 frame sand 3 seconds per frame, blood pool phase contains 5 frames and 1 minute per frame, delayed phase was performed 2.5 hour later. According to the results of three-phase bone scan, the patients were divided into 2 groups: normal and abnormal groups. The abnormal group includes early phase positive,delay positive and all three phase positive sets. The comparing among the 3 sets were analyzed by chi-square test and other statistic means.Results: There were 54 patients who had suffered lung cancer, breast cancer and other cancer,involved in this study, 34 males and 20 females, ranged age 17 to 88 years, were normal in 15 cases,positive in 22 cases, the results in delayed phase were positive in 9 cases, blood flow and blood pool phase showed blood flow changes in 4 cases and soft tissue tumors were seen in 4 cases. Three phase bone scan was more sensitive than delayed whole body bone scan in detecting the abnormal sites (p 0.05) The sensitivity of detecting tumors in blood flow and blood pool phase,delayed phase were respectively lower than in three phase bone scan (p<0.001).Conclusion: It is more sensitivity of detecting tumor lesions in three phase bone scan than in delayed phase whole body bone scan and the changes of blood flow and soft tissue can be seen in three phase bone scan

    A prospective evaluation of the effects on endometrium of third generation aromatase inhibitors (AIs), administered as adjuvant up-front therapy or switched therapy in menopausal patients suffering from breast cancer. Forty-five patients suffering from estrogen-receptor positive breast cancer were treated with AIs as adjuvant endocrine therapy; 27 patients switched from tamoxifen to AIs (group 1) due to adverse medical events related to tamoxifen intake (22 patients) or to an extended endocrine treatment after 60 months of tamoxifen therapy (5 patients); whereas 18 patients received AIs as up-front adjuvant therapy (group 2). All patients underwent endometrial investigation before the start of AIs therapy and, thereafter, at 12 month intervals. Endometrial assessment was based on Transvaginal Ultrasonography (TU), followed by hysteroscopy and endometrial biopsy when a double layered endometrial stripe above 4 mm was measured on the longitudinal plane of uterine scanning. Six patients, showing endometrial hyperplasia before the start of AIs therapy, underwent hysteroscopy on a yearly basis, disregarding the endometrial thickness measured by TU. Histopathologic results on endometrial biopsies represented the reference test in order to estimate the prevalence of endometrial morbidity. Demographic and clinical variables evaluated (age, parity, age at menarche and menopause, Body Mass Index, previous chemotherapy and radiotherapy) did not differ in groups 1 and 2. The average period of endometrial surveillance after the start of AIs therapy was 24.8 +/-10.8 months for group 1 and 21.4 +/- 11.5 months for group 2. A progressive decrease of endometrial thickness, from 8.2 +/- 5.0 to 3.0 +/- 1.2 in group 1 and from 4.7 +/- 4.3 to 1.9 +/- 0.3 in group 2, was found before the start and after 36-48 months of AIs therapy. The second line endometrial investigations' rate dropped from 70.3% to 12.5% in group 1 and from 27.7% to 0.0% in group 2, at baseline and after 36-48 months

    Purpose/Objective: To reduce the incidence of radiotherapy induced xerostomia, we developed techniques of external beam irradiation with preservation of parotid function for patients with early to intermediate stage carcinomas of the head and neck. This analysis reports the efficacy of our methods. Materials and Methods: From 1985 to 1993, 42 patients with early to intermediate stage (T 1-3 N 0-2 M 0 ) head and neck carcinomas received a course of external beam radiotherapy. There were 13 patients with carcinoma of the oropharynx, 26 with carcinomas of the oral cavity and 3 with carcinomas of the hypopharynx (lateral wall). 7 patients received a course of definitive radiotherapy (66 to 72 Gy), while 35 patients received a course of postoperative radiotherapy (60-66 Gy). The fraction size was 2 Gy per day. In terms of treatment planning, the primary site (plus a margin) and the ipsilateral neck were covered by the irradiation volume. The ipsilateral parotid gland was within the treatment volume while the contralateral parotid gland was not. The most frequently used field arrangement was a paired wedge fields with an AP (medially just across the mid-line) and an ipsilateral posterior oblique field (usually 30 deg. off vertical axis with a spinal cord block). Multiple level of contours were taken and transmission blocks were used to improve dose homogeneity. In all patients, the ipsilateral parotid gland (and the neck) was irradiated while the contralateral parotid gland (and the neck) was not. Results: With a median follow up of 4 years (ranged from 1.5 to 9 years), only one patient developed symptomatic xerostomia. None had radiation induced dental caries. No patient developed recurrent disease in the contralateral neck. The local control rate was (38(42)) (90%) in the primary site and(41(42)) (98%) in the ipsilateral neck. Conclusion: With appropriate treatment planning, external beam irradiation with parotid function preservation can be achieved. Our results

    The aim of this study was to report the feasibility of volumetric-modulated arc therapy (VMAT) in the postoperative irradiation of the vaginal vault. Moreover, the VMAT technique was compared with 3D conformal radiotherapy (3D-CRT) and fixed-field intensity-modulated radiotherapy (IMRT), in terms of target coverage and organs at risk sparing. The number of monitor units and the delivery time were analyzed to score the treatment efficiency. All plans were verified in a dedicated solid water phantom using a 2D array of ionization chambers. Twelve patients with endometrial carcinoma who underwent radical hystero-adenexectomy and fixed-field IMRT treatments were retrospectively included in this analysis; for each patient, plans were compared in terms of dose-volume histograms, homogeneity index, and conformity indexes. All techniques met the prescription goal for planning target volume coverage, with VMAT showing the highest level of conformity at all dose levels. VMAT resulted in significant reduction of rectal and bladder volumes irradiated at all dose levels compared with 3D-CRT. No significant differences were found with respect to IMRT. Moreover, a significant improvement of the dose conformity was reached by VMAT technique not only at the 95% dose level (0.74 vs. 0.67 and 0.62) but also at 50% and 75% levels of dose prescription. In addition, VMAT plans showed a significant reduction of monitor units by nearly 28% with respect to IMRT, and reduced treatment time from 11 to <3 minutes for a single 6-Gy fraction. In conclusion, VMAT plans can be planned and carried out with high quality and efficiency for the irradiation of vaginal vault alone, providing similar or better sparing of organs at risk to fixed-field IMRT and resulting in the most efficient treatment option. VMAT is currently our standard approach for radiotherapy of low-risk endometrial cancer.

    To estimate intra- and interrater agreement and reliability with regard to describing ultrasound images of the endometrium using the International Endometrial Tumor Analysis (IETA) terminology. Four expert and four non-expert raters assessed videoclips of transvaginal ultrasound examinations of the endometrium obtained from 99 women with postmenopausal bleeding and sonographic endometrial thickness ≥ 4.5 mm but without fluid in the uterine cavity. The following features were rated: endometrial echogenicity, endometrial midline, bright edge, endometrial-myometrial junction, color score, vascular pattern, irregularly branching vessels and color splashes. The color content of the endometrial scan was estimated using a visual analog scale graded from 0 to 100. To estimate intrarater agreement and reliability, the same videoclips were assessed twice with a minimum of 2 months' interval. The raters were blinded to their own results and to those of the other raters. Interrater differences in the described prevalence of most IETA variables were substantial, and some variable categories were observed rarely. Specific agreement was poor for variables with many categories. For binary variables, specific agreement was better for absence than for presence of a category. For variables with more than two outcome categories, specific agreement for expert and non-expert raters was best for not-defined endometrial midline (93% and 96%), regular endometrial-myometrial junction (72% and 70%) and three-layer endometrial pattern (67% and 56%). The grayscale ultrasound variable with the best reliability was uniform vs non-uniform echogenicity (multirater kappa (κ), 0.55 for expert and 0.52 for non-expert raters), and the variables with the lowest reliability were appearance of the endometrial-myometrial junction (κ, 0.25 and 0.16) and the nine-category endometrial echogenicity variable (κ, 0.29 and 0.28). The most reliable color Doppler variable was color score (mean weighted

    Between 1967 and 1976, 82 patients who had epithelial carcinoma of the ovary and were treated with surgery and postoperative radiation therapy, respectively, were studied. Of these patients, 35% had Stage I disease, 16% Stage II, 45% Stage III, and 4% Stage IV. Survival at five years was 96% for Stage I patients, 60% for Stage II, and 60% for Stage III. No stage IV patient survived past two years. Patients with Stage III disease treated by whole-abdominal irradiation with a pelvic boost did better than those who received 3000 rad or less to the pelvis. Radiation therapy continues to be an important treatment modality in epithelial carcinoma of the ovary, particularly in patients with minimal tumor burden. Long-term complications were primarily abdominal

    Resection is currently the only established reasonable therapeutic option with curative potential in pancreatic and ampullary carcinoma. The aim of the study was i) to analyze value and results of surgical therapy and ii) to detect the prognostic parameters, which determine significantly higher survival rates. Two-hundred-twenty patients with pancreatic and ampullary carcinoma (mean age, 61.4 years; 104 females/116 males) underwent surgery. Histologic investigation revealed 19 carcinomas of the papilla of Vater and 201 ductal pancreatic carcinomas. In 126 patients, stage IV a or b tumors were found, in addition, stage I (n =26), II (n = 17) and III (n = 51). Survival-rate was determined according to the method by Kaplan/Meier. Survival was compared using log-rank test. Association of several or multiple parameters with survival was tested using Cox model. Hundred-ten patients underwent tumor resection with primary curative intention (50 %): 96 resections of the pancreatic head, 2 total pancreatectomies and 12 left resections of the pancreas. R0-resection was achieved in 94 patients (42.7 %), whereas intervention was classified R1 in 10 and R2 in 6 cases. In addition, 60 palliative interventions (28 gastroenterostomies, 17 biliodigestive anastomoses, 15 anastomoses at both sites) and 50 explorative laparotomies were performed. In 42.3 % of patients, postoperative complications were found, but only 12/220 individuals died (overall letality, 5.4 %). Postoperative letality of curative pancreatic resections was 3.6 % (palliative intervention, 6.7 %; explorative laparotomy, 8.8 %). Five-year survival-rate of carcinoma of the papilla of Vater and pancreatic carcinoma was 73.3 % and 16.2 %, respectively (median survival time was 66.0 and 14.0 months, respectively). Taken together all other interventions, median survival time ranged between 4.0 (palliative intervention) to 10.0 months (R1-resection). No patient survived 5 years. Therefore, the most relevant prognostic

    Prostaglandin E2 (PGE2) receptor 3 (EP3) regulates tumor cell proliferation, migration, and invasion in numerous cancers. The role of EP3 as a prognostic biomarker in endometrial cancer remains unclear. The primary aim of this study was to analyze the prognostic significance of EP3 expression in endometrial cancer. We analyzed the EP3 expression of 140 endometrial carcinoma patients by immunohistochemistry. RL95-2 endometrial cancer cell line was chosen from four endometrial cancer cell lines (RL95-2, Ishikawa, HEC-1-A, and HEC-1-B) according to EP3 expression level. Treated with PGE2 and EP3 antagonist, RL95-2 cells were investigated by MTT, BrdU, and wound healing assay for functional assessment of EP3. EP3 staining differed significantly according to WHO tumor grading in both whole cohort (p = 0.01) and the subgroup of endometrioid carcinoma (p = 0.01). Patients with high EP3 expression in their respective tumors had impaired progression-free survival as well as overall survival in both cohorts above. EP3 expression in the overall cohort was identified as an independent prognostic marker for progression-free survival (HR 1.014, 95%CI 1.003-1.024, p = 0.01) when adjusted for age, stage, grading, and recurrence. Treatment with EP3 antagonists induced upregulation of estrogen receptor β and decreased activity of Ras and led to attenuated proliferation and migration of RL95-2 cells. EP3 seems to play a crucial role in endometrial cancer progression. In the context of limited systemic treatment options for endometrial cancer, this explorative analysis identifies EP3 as a potential target for diagnostic workup and therapy.

    Full Text Available Germline mutation of DNA mismatch repair (MMR genes is a cause of Lynch syndrome. Methylation of MutL homolog 1 (MLH1 and MutS homolog 2 (MSH2 has been detected in peripheral blood cells of patients with colorectal cancer. This methylation is referred to as epimutation. Methylation of these genes has not been studied in an unselected series of endometrial cancer cases. Therefore, we examined methylation of MLH1, MSH2, and MSH6 promoter regions of peripheral blood cells in 206 patients with endometrial cancer using a methylation-specific polymerase chain reaction (MSP. Germline mutation of MMR genes, microsatellite instability (MSI, and immunohistochemistry (IHC were also analyzed in each case with epimutation. MLH1 epimutation was detected in a single patient out of a total of 206 (0.49%—1 out of 58 (1.72% with an onset age of less than 50 years. The patient with MLH1 epimutation showed high level MSI (MSI-H, loss of MLH1 expression and had developed endometrial cancer at 46 years old, complicated with colorectal cancer. No case had epimutation of MSH2 or MSH6. The MLH1 epimutation detected in a patient with endometrial cancer may be a cause of endometrial carcinogenesis. This result indicates that it is important to check epimutation in patients with endometrial cancer without a germline mutation of MMR genes.

    Full text: A multi-centre study was sponsored by the IAEA to assess the safety and efficacy of trans-arterial Rhenium-188 HDD Lipiodol in the treatment of inoperable Hepatocellular Carcinoma. The radioconjugate was prepared by using an HDD kit and Lipiodol. Over three years, 185 patients received at least one treatment. The dose administered was based on radiation absorbed dose to critical normal organs, calculated following a ''scout'' dose (approximately 4 mCi) of radioconjugate. The organs at greatest risk for radiation toxicity are the liver, the lung and the bone marrow. An Excel spreadsheet was used to determine maximum tolerated activity, defined as the amount of radioactivity calculated to deliver no more than 12 Gy to lungs, 30 Gy to liver, or 1.5 Gy to bone marrow. A single treatment was given to 134 patients, 42 patients received two doses, 8 received three and one patient received four treatments. The total injected activity including the scout dose during the first treatment ranged from 21 to 364 mCi (average 108 mCi). Patients were followed for at least l2 weeks after therapy. The clinical parameters evaluated included toxicity, response as determined objectively by contrast enhanced computed tomography, palliation of symptoms, overall survival, performance status (Karnofsky), and hepatic function (Child's classification). Liver function tests, serum alpha-fetoprotein (AFP) levels and complete blood counts were done at each follow-up visit. Side effects were minimal and usually presented as loss of appetite, right hypochondrial discomfort and low-grade fever. Liver function tests at 24 and 72 hours showed no significant changes and complete blood counts at 1 week, 4 weeks and 12 weeks showed no changes (no bone marrow suppression). Data on largest tumour diameter after therapy and/or tumour response as evaluated from CT scans are available for 88 patients. Complete disappearance of tumour was recorded in 3 (3%), partial response in 19 (22%), stable

    Background: First clinical data on a new intracavitary afterloading boost method for anal canal carcinoma is reported. Patients and Methods: 20 consecutive patients (T1 5%, T2 70%, T3 20%, T4 5%; N0 75%, N1 10%, N2 15%; all M0) treated with external beam pelvic radiotherapy (median dose 56 Gy, range 46-64 Gy), simultaneous 5-FU and mitomycin (in 75%) and an intracavitary afterloading boost (one or two fractions of 5 Gy at 5 mm depth) were analyzed after a mean {+-}SD follow-up for living patients of 4.4{+-}2.1 years. Quality of life (QoL) and anorectal manometry parameters were assessed in ten colostomy-free survivors. Results: Overall, recurrence-free and colostomy-free survival at 5 years were 84%, 79% and 69%, respectively. No death was tumorrelated. The only local failure was successfully salvaged by local excision. All three colostomies were performed for toxicity. Resting pressure and maximum squeeze pressure of the anal sphincter were reduced by 51% and 71%, as compared with control subjects, but quality of life was similar compared to healthy volunteers. Conclusion: the described regimen is highly effective but associated with increased toxicity. (orig.)

    Heavy menstrual bleeding is a common problem that can severely affect quality of life. To compare bipolar radiofrequency endometrial ablation and thermal balloon ablation for heavy menstrual bleeding in terms of efficacy and health-related quality of life (HRQoL). Online registries were systematically searched using relevant terms without language restriction from inception to November 24, 2016. Randomized control trials or cohort studies of women with heavy menstrual bleeding comparing the efficacy of two treatments were eligible. Data were extracted. Results were expressed as risk ratios (RRs) or weighted mean differences (WMDs) with 95% confidence intervals (CIs). Six studies involving 901 patients were included. Amenorrhea rate at 12 months was significantly higher after bipolar radiofrequency endometrial ablation than after thermal balloon ablation (RR 2.73, 95% CI 2.00-3.73). However, no difference at 12 months was noted for dysmenorrhea (RR 1.04, 95% CI 0.68-1.58) or treatment failure (RR 0.78, 95% CI 0.38-1.60). The only significant difference for HRQoL outcomes was for change in SAQ pleasure score (12 months: WMD -3.51, 95% CI -5.42 to -1.60). Bipolar radiofrequency endometrial ablation and thermal balloon ablation reduce menstrual loss and improve quality of life. However, bipolar radiofrequency endometrial ablation is more effective in terms of amenorrhea rate and SAQ pleasure. © 2017 International Federation of Gynecology and Obstetrics.

    Full Text Available Background: The animal models of endometriosis could be a valuable alternative tool for clarifying the etiology of endometriosis. Objective: In this study two endometriosis models at the morphological and molecular levels was evaluated and compared. Materials and Methods: The human endometrial tissues were cut into small fragments then they were randomly considered for transplantation into γ irradiated mice as model A; or they were isolated and cultured up to fourth passages. 2×106 cultured stromal cells were transplanted into γ irradiated mice subcutaneously as model B. twenty days later the ectopic tissues in both models were studied morphologically by Periodic acid-Schiff and hematoxylin and eosin staining. The expression of osteopontin (OPN and matrix metalloproteinase 2 (MMP2 genes were also assessed using real time RT-PCR. 17-β estradiol levels of mice sera were compared before and after transplantation. Results: The endometrial like glands and stromal cells were formed in the implanted subcutaneous tissue of both endometriosis models. The gland sections per cubic millimeter, the expression of OPN and MMP2 genes and the level of 17-β estradiol were higher in model B than model A (p=0.03. Conclusion: Our observation demonstrated that endometrial mesenchymal stromal cells showed more efficiency to establish endometriosis model than human endometrial tissue fragments.

    Introduction: Endometrial carcinoma is the most frequent gynecological cancer in developed countries. Until the latest FIGO classification on 1988, the times of BT and surgery were uncertain for early stages. This paper reviews the results of the retrospective analysis of patients with early endometrial carcinoma (stages I and II) treated with pre- or postoperative BT +/- external radiotherapy (ERT) at the Institute Gustave Roussy from january 1985 to december 1989. Materials and Methods: 220 patients stage I and 21 patients stage II were eligible. The protocol was primary BT (106 patients) 50 Gy to the upper third of the vagina, an immediate radical hysterectomy with pelvic lymph node picking and according to the histological results, ERT (33 patients). After the surgical classification, postop BT was performed in 47 patients. 55 patients received another radiosurgical treatment. Results: With a follow-up of 3 years, the results were: after primary BT, the dose to pelvic walls, the kerma, the volume thickness and the reference isodose volume were higher. Surgery post BT was performed on a mean of 12 days, and postop BT on a mean of 97 days. Among 181 lymph node dissections, only 5 patients had N+, 38 histologies showed no myometrial invasion: 112, (1(3)); 64, (2(2)); and 20, (3(3)). The differentiation of the tumor was indirectly correlated with myometrial invasion. 88 patients received ERT, to a mean dose of 45 Gy. The overall survival was 91% at 2 years and 81% at 5 years. For patients with primary BT, the survival was 96% at 2 and 5 years. For primary surgery was 98 and 88% at 2 and 5 years DFS at 2 and 5 years for preop BT was 85% and 76%, for postop BT 95% and 92%, 5 patients had grade 3 complications. The metastases, including paraaortic lymph nodes were 6. 14 recurrences occurred, in external iliac nodes, common iliacs, pelvis, abdomen, and 4 in vagina. The prognostic factors were in univariate study, the surgical stage. In multivariate, myometrial invasion

    Objective: To determine the efficacy and complications of adjuvant high dose rate (HDR) vaginal cuff brachytherapy (VCB) in patients (pts) with low risk endometrial carcinoma. Materials and Methods: Since 1989, 154 patients were treated with outpatient adjuvant VCB for low risk endometrial cancer (Stage IA-14%, Stage IB-82%). Four percent of patients with stage IC disease were treated with VCB only because of medical contraindications to pelvic radiation. Patients had the following histologic grades: 53% grade 1, 40% grade 2, 5% grade 3 and 3% unknown (99%-adenocarcinoma, <1% papillary serous histology). Seventy-three percent of patients had their surgery (TAH-BSO) performed at an outside institution with minimal surgical assessment of the lymph nodes. At a median of 6 weeks after surgery, patients were treated with 2 HDR VCB insertions delivered 1 week apart. Ovoids were placed at the vaginal apex to deliver 16.2 Gy per fraction to the vaginal surface (LDR equivalent of 60 Gy at 100 cGy/h) under conscious outpatient sedation. All clinical endpoints were calculated using the Kaplan Meier method. Complications were scored using the RTOG 5-tiered system. Results: The median time in the brachytherapy suite was 60 minutes with no acute complications observed. With a median follow-up of 33 months (3-79 months), the 4-year overall and disease-free survival were 93% and 96% respectively. Five patients (3%) recurred: 2 intra-abdominally, 1 with lung metastases, and 2 in the pelvic lymph nodes. There were no vaginal cuff recurrences. The single patient with an isolated pelvic sidewall recurrence was salvaged with pelvic RT. Six patients developed a small area of asymptomatic necrosis at the vaginal cuff, which spontaneously healed at a median time of 4 months. There were no grade 3 or greater late tissue toxicities. No patient experienced significant vaginal stenosis, with 20% of the patients experiencing mild fibrosis of the vaginal apex. Conclusions: Adjuvant HDR VCB in 2

    Therapeutic results of 33 primary cases of maxillary sinus carcinoma treated with irradiation and intraarterial infusion of 5-FU between 1972 and 1984 were analyzed. The 5-year crude survival rate for the group with stage T2 carcinoma (n=10) was 50.0%, and for those with T3 (n=15) and T4 (n=8) it was 46.7% and 25.0%, respectively. The overall 5-year crude survival rate was 42.4%. Eight patients who did not undergo maxillectomy survived for 5 years after irradiation and intraarterial infusion. Recurrence of the tumor after the irradiation and intraarterial infusion occurred in 63.6%, and was frequently observed at the ethmoidal region and the orbita. In the areas in which the tumor extended to regions such as the ethmoid sinus and orbita, which are nourished by arteries other than the maxillary artery, conventional intraarterial infusion was ineffective for complete tumor eradication. Therefore, in most of the patients with advanced maxillary sinus carcinoma, partial or total maxillectomy following combined therapy of intraarterial infusion and irradiation is necessary to improve a prognosis.

    To improve the surgical rate and the quality of life (QOL) for patients with advanced low rectal carcinoma, we investigated whether preoperative treatments (irradiation and hyperthermia and 5-fluorouracil (5-FU) suppository, irradiation and hyperthermia, irradiation and 5-FU suppository, irradiation alone and 5-FU suppository alone) were useful. The tumor shrinkage rate after preoperative treatments was highest in the irradiation, hyperthermia and 5-FU suppository group. Pathologically complete regression was observed in the 2 of 18 cases (12%). According to our criteria of histological changes, the irradiation, hyperthermia and 5-FU suppository group showed the greatest effectiveness. The 4 year postoperative survival rate and the 4 year local recurrence rate were 100% and 8% in the irradiation, hyperthermia and 5-FU suppository group and the data suggest that these results were the best of the 5 treatments. After the carcinoma was shrunk after irradiation, hyperthermia and 5-FU suppository, the patients could receive curatively a sphincter-saving operation (super-low anterior resection and transanal rectal resection). The fecal continence of 7 patients after sphincter-saving operations was increased as good by manometric study, defecography and clinical evaluation. In conclusion, our data suggest that the preoperative combined treatment of irradiation, hyperthermia and 5-FU suppository prevents local recurrence and increases the possibility of a sphincter-saving operation for advanced rectal carcinoma.

    Full Text Available Abstract Background Many potassium ion (K+ channels function as oncogenes to sustain growth of solid tumors, but their role in cancer progression is not well understood. Emerging evidence suggests that the early progenitor cancer cell subpopulation, termed tumor initiating cells (TIC, are critical to cancer progression. Results A non-selective antagonist of multiple types of K+ channels, tetraethylammonium (TEA, was found to suppress colony formation in endometrial cancer cells via inhibition of putative TIC. The data also indicated that withdrawal of TEA results in a significant enhancement of tumorigenesis. When the TIC-enriched subpopulation was isolated from the endometrial cancer cells, TEA was also found to inhibit growth in vitro. Conclusions These studies suggest that the activity of potassium channels significantly contributes to the progression of endometrial tumors, and the antagonists of potassium channels are candidate anti-cancer drugs to specifically target tumor initiating cells in endometrial cancer therapy.
