Abstract
The aim of this study was to assess the diagnostic accuracy of subjective ultrasound evaluation of myometrial invasion of endometrial cancer and to compare its accuracy to objective methods. All consecutive patients with histologically proven endometrial cancer, who underwent ultrasound evaluation followed by surgical staging between January 2009 and December 2011, were prospectively enrolled. Myometrial invasion was evaluated by subjective assessment using ultrasound (<50% or ≥50%) and calculated as deepest invasion/normal myometrium ratio (Gordon's ratio) and as tumor/uterine anteroposterior diameter ratio (Karlsson's ratio). Histological assessment from hysterectomy was considered the gold standard. Altogether 210 patients were prospectively included. Subjective assessment and two objective ratios were found to be statistically significant predictors of the myometrial invasion (AUC = 0.65, p value < 0.001). Subjective assessment was confirmed as the most reliable method to assess myometrial invasion (79.3% sensitivity, 73.2% specificity, and 75.7% overall accuracy). Deepest invasion/normal myometrium (Gordon's) ratio (cut-off 0.5) reached 69.6% sensitivity, 65.9% specificity, and 67.3% overall accuracy. Tumor/uterine anteroposterior diameter (Karlsson's) ratio with the same cut-off reached 56.3% sensitivity, 76.4% specificity, and 68.1% overall accuracy. The subjective ultrasound evaluation of myometrial invasion performed better than objective methods in nearly all measures but showed statistically significantly better outcomes only in case of sensitivity.

Abstract
OBJECTIVE To review the diagnostic accuracy of transvaginal ultrasound (TVS) in the preoperative detection of deep myometrial infiltration in patients with endometrial cancer, comparing subjective and objective methods. METHODS An extensive search was performed in MEDLINE (PubMed) and EMBASE for studies published between January 1989 and December 2014. The eligibility criterion was use of TVS for preoperative assessment of myometrial infiltration by subjective evaluation and/or objective measurements. Objective measurements included, specifically, the approaches of Gordon (ratio of the distance between endometrium-myometrium interface and maximum tumor depth to the total myometrial thickness) and Karlsson (endometrial tumor thickness/anteroposterior uterine diameter ratio), in women with endometrial cancer, using the surgical pathological data as a reference standard. Study quality was assessed using the QUADAS-2 tool. RESULTS Our extended search identified a total of 184 citations, among which we examined the full text of 24 articles. Overall pooled sensitivity, specificity, positive likelihood ratio (LR+) and negative likelihood ratio (LR-) of TVS for detecting deep myometrial infiltration were 82% (95% CI, 76-87%), 81% (95% CI, 76-85%), 4.3 (95% CI, 3.6-5.3) and 0.22 (95% CI, 0.16-0.30), respectively. We did not observe differences among the three methods in terms of diagnostic performance. Significant heterogeneity was found for sensitivity and specificity of all three methods (I(2) range, 60.6-95.0). The main limitation was that very few studies compared different approaches in the same set of patients. CONCLUSION Diagnostic performance of TVS for detecting deep myometrial infiltration in women with endometrial cancer is moderate.

Abstract
OBJECTIVE To evaluate the diagnostic performance of gross examination and transvaginal ultrasonography in the assessment of the depth of myometrial infiltration when they are used alone or together as a combined test. STUDY DESIGN The data of 219 consecutive patients with a diagnosis of endometrial cancer were evaluated retrospectively. Transvaginal ultrasound was carried out as a part of the routine preoperative work-up within three days of surgical intervention in all cases. All patients underwent hysterectomy with bilateral salpingo-oophorectomy and routine surgical staging and all uterine specimens were examined immediately after hysterectomy. The depth of myometrial invasion was classified into two groups: no or <50% invasion and ≥50% invasion. The findings of ultrasound and intraoperative gross examination were compared with the final histopathological results. The data of these two methods were integrated to evaluate the diagnostic performance of the combined test. If the results of myometrial invasion evaluation were different for the same patient, the deeper one (the depth of invasion ≥50%) was accepted. RESULTS Sensitivity, specificity, PPV, NPV and accuracy of preoperative ultrasonography in predicting myometrial infiltration ≥50% were 62%, 81%, 60%, 82%, and 75% respectively. The corresponding rates for intraoperative gross examination were 61%, 88%, 70%, 83% and 79%, respectively. For the combined test they were 78%, 76%, 60%, 88% and 70% respectively. There was no statistically significant difference in sensitivity and specificity between ultrasound and gross examination. The sensitivity of the combined test was significantly higher than that of ultrasound and gross examination (p=0.001 and p<0.0001, respectively). The specificity of the combined test was significantly lower than that of TVS and gross examination (p=0.008 and p<0.0001, respectively). CONCLUSION Combining ultrasonography and intraoperative gross examination may be a good option to assess the depth of myometrial invasion, as it has a higher sensitivity and negative predictive value in comparison to using these methods alone.

Abstract
AIM To determine whether clinical outcomes show a benefit from extended hysterectomy in patients with early endometrial cancer. METHODS We reviewed the medical records of 101 patients who had endometrial cancer with clinical stage I disease. All the patients were surgically staged, and two types of hysterectomy, simple hysterectomy (SH) or extended hysterectomy (EH), were performed by surgeon's preference. The postoperative pathology findings, recurrence rate and disease-free survivals (DFS) between the two groups were compared. RESULTS Sixty-six patients and thirty-five patients underwent SH and EH, respectively. At subsequent surgical staging, seven patients (10.6%) in the SH and four (11.4%) in EH group were upgraded to stage II or III disease. The surgical and pathological features were not different between the groups. Though the recurrence rate was lower in the EH group (9.09% for SH vs 2.86% for EH), it showed no statistical significance (P = 0.241). The 5-year DFS (88.2% for SH vs 96.0% for EH) showed no statistically significant difference between the groups either (P = 0.242). CONCLUSION Compared to SH, EH did not have any prognostic benefit in clinical stage I endometrial cancer. Until the therapeutic role of the EH is determined by further studies using a larger sample size, SH remains the treatment of choice in patients with early endometrial cancer, and surgeons should not perform extended operation without definite evidence of the disease.

Abstract
Endometrial cancer is the most common gynaecological malignancy and the incidence rising. Prognosis depends on age of patient, histological grade, depth of myometrial invasion and cervical invasion and lymph node metastases. Myometrial invasion and accurate cervical involvement cannot be predicted clinically. Pre-treatment knowledge of these criteria is advantageous in order to plan treatment. The clinical challenge is to effectively select patients at risk of relapse for more radical treatment whilst avoiding over treating low risk cases. This is important as endometrial cancer predominately occurs in postmenopausal women with co-morbidities. Modern imaging provides important tools in the accurate pre-treatment assessment of endometrial cancer and may optimize treatment planning. However, there is little consensus to date on imaging in the routine preoperative assessment of endometrial carcinoma and practice varies amongst many gynaecologists. Transvaginal ultrasound is often the initial imaging examination for women with uterine bleeding. However, once the diagnosis of endometrial cancer has been made, contrast-enhanced magnetic resonance imaging (MRI) provides the best assessment of the disease. The results of contrast-enhanced MRI may identify patients who need more aggressive therapy and referral to a cancer centre. In this article we review the role of imaging in the diagnosis and staging/preoperative assessment of endometrial carcinoma.

Abstract
OBJECTIVES Preoperative knowledge of the depth of myometrial infiltration is important in patients with endometrial carcinoma. This study aimed at assessing the value of histopathological parameters obtained from an endometrial biopsy (Pipelle de Cornier; results available preoperatively) and ultrasound measurements obtained after transvaginal sonography with color Doppler imaging in the preoperative prediction of the depth of myometrial invasion, as determined by the final histopathological examination of the hysterectomy specimen (the gold standard). METHODS We first collected ultrasound and histopathological data from 97 consecutive women with endometrial carcinoma and divided them into two groups according to surgical stage (Stages Ia and Ib vs. Stages Ic and higher). The areas (AUC) under the receiver-operating characteristics curves of the subjective assessment of depth of invasion by an experienced gynecologist and of the individual ultrasound parameters were calculated. Subsequently, we used these variables to train a logistic regression model and least squares support vector machines (LS-SVM) with linear and RBF (radial basis function) kernels. Finally, these models were validated prospectively on data from 76 new patients in order to make a preoperative prediction of the depth of invasion. RESULTS Of all ultrasound parameters, the ratio of the endometrial and uterine volumes had the largest AUC (78%), while that of the subjective assessment was 79%. The AUCs of the blood flow indices were low (range, 51-64%). Stepwise logistic regression selected the degree of differentiation, the number of fibroids, the endometrial thickness and the volume of the tumor. Compared with the AUC of the subjective assessment (72%), prospective evaluation of the mathematical models resulted in a higher AUC for the LS-SVM model with an RBF kernel (77%), but this difference was not significant. CONCLUSIONS Single morphological parameters do not improve the predictive power when compared with the subjective assessment of depth of myometrial invasion of endometrial cancer, and blood flow indices do not contribute to the prediction of stage. In this study an LS-SVM model with an RBF kernel gave the best prediction; while this might be more reliable than subjective assessment, confirmation by larger prospective studies is required.

Abstract
In a woman at the age of 30, carcinoma of the endometrium was diagnosed after hysteroscopic polypectomy. Her family history fulfilled Bethesda diagnostic criteria for Lynch syndrome or hereditary nonpolyposis colon cancer. Conservative treatment was chosen based on the tumor grade, her age, and her desire for pregnancy. Three months after high-dose progesterone treatment successful conception was achieved. In this report, we suggest that individual approach should be considered in young women with low-grade endometrial carcinoma, positive family history, and unfulfilled motherhood.

Abstract
OBJECTIVE To determine, according to histological tumor grade, the reliability of preoperative endovaginal ultrasound in the detection of myometrial invasion in patients with stage I endometrial cancer. PATIENTS AND METHODS Sixty-one patients with stage I endometrial carcinoma were evaluated with preoperative endovaginal ultrasound compared to postoperative results of pathologic examination, in a six-year retrospective study. RESULTS Twenty-nine patients had a deep myometrial invasion (stage IC). The mean endometrial thickness was 9.5 mm in stage IA, 17.0 mm in stage IB and 20.0 mm in stage IC disease (P = 0.01). The sensitivity and the specificity of the ultrasound in the assessment of myometrial invasion in grade 1 tumors were 100% and 93.7%, respectively. They fell to 69.2% and 88.9% for high-grade tumors. The global accuracy of ultrasound was 82%. DISCUSSION AND CONCLUSIONS The performance of preoperative ultrasound varies according to the literature. The association of morphological and morphometric criteria enables an increase in the sensitivity of the exam. In grade 1 tumors, the preoperative endovaginal ultrasound could help in identifying a group of patients at low risk of lymph node metastasis for which a pelvic lymphadenectomy would be avoidable.

Abstract
The goal of this study was to determine diagnostic accuracy of preoperative transvaginal sonography (TVS) to assess myometrial infiltration in patients with endometrial cancer and to determine the possibility of preoperatively selecting low-stage endometrial cancer patients at high risk of lymph node metastases. The depth of myometrial infiltration of endometrial cancer was assessed using TVS before or after curettage. Infiltration was classified as superficial if less than half of the myometrium was involved, otherwise it was classified as deep infiltration. Results were compared with the histology results of the definitive specimens. Patients were classified as high risk when they satisfied two of the following three criteria: 60 years of age or older; deep myometrial infiltration; and poorly differentiated or undifferentiated tumor. A total of 93 patients from 11 clinics were analyzed. The mean age was 66.1 years (SD +/- 11.4). The sonography and histology findings were in agreement in 69 of 93 patients. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV), of "deep infiltration" by preoperative TVS were 79% (95% CI 0.65-0.93), 72% (95% CI 0.61-0.83), 61% (95% CI 0.46-0.75), and 86% (95% CI 0.76-0.96), respectively. Combining tumor grade and myometrial infiltration in the hysterectomy specimen and age, 30 of 81 patients were classified as high-risk patients. Sensitivity and PPV, specificity, and NPV for preoperative diagnosis of high risk were 80% (95% CI 0.65-0.94) and 88% (95% CI 0.79-0.97), respectively. Preoperative assessment of myometrial tumor infiltration using just TVS is only moderately reliable in endometrial cancer patients. If the results of TVS, however, are combined with the patient's age and the degree of tumor differentiation in curettings, it is possible to preoperatively select endometrial cancer patients with a high risk of pelvic lymph node metastases with sufficient reliability.

Abstract
Thirty-nine patients with endometrioid adenocarcinoma (EA) and atypical hyperplasia (AH) of the endometrium who received conservative treatment to preserve fertility were collected from member institutions of the Japan Gynecologic Oncology Study Group. Twenty-nine and ten were originally diagnosed with EA without myometrial invasion and AH, respectively. We performed a central pathological review to make definite diagnoses, and the diagnosis of EA in 29 cases was changed to AH in ten, complex hyperplasia in three and atypical polypoid adenomyoma in three, and AH in ten was changed to EA in one and simple hyperplasia in one. Nine of 12 women (75%) with EA and 15 of 18 women (83%) with AH had an initial response to medroxyprogesterone acetate (MPA) treatment. Two of nine responders with EA later developed relapse, and one of them had metastasis to the left obturator lymph node. Two became pregnant, and one delivered one full-term infant. One of the responders with AH had a relapse in the endometrium. Five became pregnant, and four delivered four normal infants. The young women with endometrial carcinoma localized in the endometrium who wish to preserve fertility may be treated as successfully with MPA as those with AH.

Abstract
OBJECTIVES The relationship between locoregional lymph metastasis and tumor thickness in head and neck cancer has been well documented in recent years. Determining tumor thickness by frozen section may help the surgeon decide intraoperatively whether to perform elective neck dissection, whereas paraffin section results could be obtained at a later time for this decision. The aim of this study was to evaluate the accuracy of tumor thickness measurements obtained by macroscopic measurement and by frozen section intraoperatively in laryngeal cancer. STUDY DESIGN Prospectively we compared the tumor thickness results obtained by gross visual examination, by frozen section, and by paraffin section in 20 total, near-total, and horizontal supraglottic laryngectomy specimens. METHODS The sections were stained with hematoxylin and eosin and tumor thickness was measured under a light microscope with an ocular micrometer. RESULTS A strong correlation was found between frozen section and paraffin section tumor thickness measurements (Pearson correlation coefficient = 0.993, P <.001). Paired t test showed a 4.59 mm mean difference between macroscopic and paraffin section measurements, and a 0.76 mm mean difference between frozen and paraffin section measurements. CONCLUSION Assessment of tumor thickness in laryngeal cancer intraoperatively by frozen section is a reliable method.
