INTRODUCTION Advanced age is considered an adverse factor in endometrial cancers but may be a surrogate for other conditions that impact outcomes. The study objective was to assess the association of age with endometrial cancer features, treatment and prognosis. MATERIAL AND METHODS In this multicenter cohort study, consecutive women with endometrial cancer treated at 10 Israeli institutions between 2000 and 2014 were accrued in an assimilated database. Postmenopausal women were stratified into age groups with a cut-off of 80. Clinical, pathological and treatment data were compared using t test or Mann-Whitney test for continuous variables, and Chi-square Test or Fisher's Exact test for categorical variables. Main outcome measures included disease recurrence and disease-specific and overall survival; these were plotted using the Kaplan-Meier method and compared using the log-rank test. The association between age and recurrence and survival, adjusted for other clinical and pathological factors, was assessed using multivariable Cox regression modeling. RESULTS A total of 1764 postmenopausal women with endometrial cancer were identified. Adverse pathological features were more prevalent in older women, including high-risk histologies (35% vs 27%, P = .025), deep myoinvasion (44% vs 29%, P = .001) and lymphovascular involvement (22% vs 15%, P = .024). Surgical staging was performed less frequently among older women (33% vs 56%; P

Objective To assess whether statin use by endometrial cancer patients was associated with a survival advantage. Methods A retrospective chart review study, by the Israeli Gynecologic Oncology Group, of consecutive endometrial cancer patients who underwent surgery in one of 11 medical centers between 2002 and 2014. Clinical and pathological reports, and measures of survival were compared between statin users and nonusers. Kaplan-Meier and Cox proportional hazard models were used to assess the effect of using statins on survival measures. Results Over a mean follow-up period of 6.2 years (range, 1-12 years) for 2017 endometrial cancer patients with complete data, 663 (32.8%) used statins prior to diagnosis and 1354 (67.1%) did not. No statistically significant differences between the groups were observed for most demographic and clinical characteristics. There was no difference between statin users and nonusers in 5-year recurrence-free survival (82% vs 83%; P=0.508), disease-specific survival (86% vs 84%; P=0.549), or overall survival (77% vs 75%; P=0.901). Conclusions In this large cohort of patients with endometrial cancer, no significant associations were found between use of statins and endometrial cancer survival.

A rapid and reliable intraoperative diagnostic technique to support clinical decisions was developed using Fourier-transform infrared (FTIR) spectroscopy. Twenty-six fresh tissue samples were collected intraoperatively from patients undergoing gynecological surgeries. Frozen section (FS) histopathology aimed to discriminate between malignant and benign tumors was performed, and attenuated total reflection (ATR) FTIR spectra were collected from these samples. Digital dehydration and principal component analysis and linear discriminant analysis (PCA-LDA) models were developed to classify samples into malignant and benign groups. Two validation schemes were employed: k-fold and "leave one out." FTIR absorption spectrum of a fresh tissue sample was obtained in less than 5 minutes. The fingerprint spectral region of malignant tumors was consistently different from that of benign tumors. The PCA-LDA discrimination model correctly classified the samples into malignant and benign groups with accuracies of 96% and 93% for the k-fold and "leave one out" validation schemes, respectively. We showed that a simple tissue preparation followed by ATR-FTIR spectroscopy provides accurate means for very rapid tumor classification into malignant and benign gynecological tumors. With further development, the proposed method has high potential to be used as an adjunct to the intraoperative FS histopathology technique.

OBJECTIVE To compare the outcome of patients with uterine papillary serous cancer (UPSC) carrying a BRCA mutation with that of patients with UPSC who are BRCA wild-type. METHODS The present retrospective, multicenter cohort study included women with UPSC who were diagnosed between January 1, 1993, and December 31, 2014, and were tested for the BRCA mutation at three Israeli medical centers. Data were collected from the medical records, and patient and tumor characteristics and disease outcomes were compared between BRCA mutation carriers and noncarriers. The primary outcome was overall survival. RESULTS In total, 14 BRCA mutation carriers and 50 noncarriers were included. Both groups had similar treatment modalities (P=0.530). A non-significant trend toward BRCA mutation carriers being diagnosed more frequently at an advanced stage compared with noncarriers was observed (P=0.090). Median overall survival (25 vs 37 months; P=0.442), progression-free survival (37 vs 29 months; P=0.536), and disease-specific survival (60 vs 39 months; P=0.316) were similar between the carrier and noncarrier groups. CONCLUSIONS Although not significant, BRCA mutation carriers tended to have more advanced disease at diagnosis. However, the survival was similar irrespective of the BRCA status in this small group. Further research is needed to confirm these findings in a larger cohort.

Differential diagnosis of a uterine mass is complex and usually includes leiomyoma and sarcoma. We report a rare case of uterine Ewing sarcoma with its unique sonographic characteristics in a 37-year-old woman. Usually, the diagnosis of uterine Ewing sarcoma is made at an advanced stage. Overall, the mortality and relapse rates for Ewing sarcoma are high. In this case, the diagnosis was made at an early stage. The woman was treated surgically followed by chemotherapy Afterward, the woman was well and was followed in the oncologic gynecology unit.

Purpose This study was conducted to assess the combination of endometrial thickness, as measured by transvaginal sonography, and time since menopause, in predicting the presence of endometrial cancer in women with postmenopausal bleeding. Methods The study group consisted of 95 women with postmenopausal bleeding who underwent sonographic measurement of endometrial thickness followed by endometrial biopsy. No patient had ever received hormone replacement therapy. Results The mean endometrial thickness was significantly lower in the absence of endometrial carcinoma (6.9 ± 4.3 mm) than in its presence (13.5 ± 7.7 mm) (p < 0.005). The incidence of endometrial carcinoma increased with increases in endometrial thickness and the number of years since menopause. No patient had carcinoma when the endometrium was less than 5 mm thick, but 18.5% did when the thickness exceeded 9 mm. The incidence of cancer was 2.6% in women who had undergone menopause less than 5 years earlier but was 21.4% in women who had undergone menopause more than 15 years prior. Multiple logistic regression analysis showed that time since menopause and endometrial thickness were statistically significant predictors of endometrial carcinoma. Conclusions Time since menopause and endometrial thickness together define cutoff points for the diagnostic biopsy of tissue samples for endometrial carcinoma; that is, within a particular time interval, samspling should not be performed if the thickness is below a given value. When using cutoff points of 6 mm of endometrial thickness for women experiencing menopause 5–15 years prior and 5 mm in those going through menopause 15 or more years prior, approximately 60% of invasive procedures may be avoided. In addition, models derived by multiple logistic regression can be used to calculate a patient's risk of cancer based on her age and endometrial thickness. © 2004 Wiley Periodicals, Inc.

Uterine lymphoma is rare and tends to be misdiagnosed due to lack of specific radiologic features. Few reports have been published on the sonographic characteristics of uterine lymphoma. We present a case report of uterine lymphoma manifested by a fast growing uterus and describe the sonographic findings. © 2014 Wiley Periodicals, Inc. J Clin Ultrasound, 43:59–63, 2015

Objective. To examine the theory that the postpartum shivering phenomenon is related to feto-maternal bleed during the third stage of labor.Methods. One hundred laboring low-risk women who had a normal vaginal delivery were observed for the presence of postpartum chills. The duration of the first and second stages of labor changes in body temperature, maternal and fetal blood types and the use of epidural anesthesia were recorded. Following the delivery maternal blood was examined for the presence of fetal red blood cells using the Kleihauer-Betke stain.Results. Complete data was available in 97 patients. Post-partum chills occurred in 31 of them (32%). Women with and without chills were similar in their maternal and gestational age, the use of epidural anesthesia, and length of second stage of labor. Women with chills delivered smaller babies but the difference did not reach significance. Maternal-fetal blood group incompatibility was significantly more common among shivering than non-shivering women (48% v...
