Abstract
INTRODUCTION To assess laparoscopic management of presumed stage I endometrial cancer, and to compare gross, frozen, and paraffin section methods measuring myoinvasion. PATIENTS AND METHODS Eligible patients underwent laparoscopic exploration. Patients with preoperative grade 1 histology underwent laparoscopic-assisted vaginal hysterectomy and bilateral salpingo-oophorectomy (LAVHBSO). Pelvic and periaortic lymph node sampling (PPANS) was performed for deep (> or =50%) myoinvasion confirmed by frozen section. Patients with preoperative grade 2 or 3 histology without evidence of extrauterine metastasis underwent PPANS + LAVHBSO. RESULTS Of 50 eligible patients selected, LAVHBSO was successfully completed in all but five. There was one trocar bowel perforation. Myoinvasion depth was correlated between paraffin section and gross estimate, and between paraffin and frozen section estimate, in 89 and 90% of cases, respectively. Myoinvasion was underestimated by gross versus paraffin in three of five discrepancies, and by frozen versus paraffin section in one of three discrepancies. CONCLUSIONS Laparoscopic surgical staging for early stage endometrial cancer is feasible. Gross/frozen section methods correlate with paraffin section to measure myoinvasion. Tumor grading and gross/frozen section myoinvasion estimates can guide operative management.

Abstract
OBJECTIVES We sought to determine the accuracy of gross evaluation of the depth of myometrial invasion and the involvement of the cervix, and its value in determining the need for extensive surgery in patients with endometrial carcinoma. METHODS The intraoperative records of 256 patients operated for endometrial cancer were used to compare the gross evaluations with the final microscopic histopathological findings. In the theater, the uterus was opened and inspected after its removal. The depth of myometrial invasion was noted as less or greater than 50% using a full-thickness incision through the tumor, while cervical involvement was noted as positive or negative, based on extension of the tumor below the internal cervical os. Standard statistical calculations were used to determine accuracy, sensitivity, specificity, positive and negative predictive values, and false-positive and false-negative rates of the method. RESULTS Regarding the depth of myometrial invasion, gross evaluation could accurately predict the final result in 88.2% of patients. Sensitivity, specificity, positive, and negative predictive values were 83.7, 90.6, 82.8, and 91.1%, respectively. False-positive results were noted in 9.4% of cases and false-negative in 16.3%. Analysis of the characteristics of the false-negative patients showed that they had aggressive variant tumors, tumors of advanced grade, and tumors that more frequently had developed from an atrophic endometrium. With respect to cervical involvement, gross evaluation had an overall accuracy of 98.5%, 0% false-positive rate, 11.5% false-negative rate, 88.5% sensitivity, 100% specificity, 100% positive predictive value, and 98.3% negative predictive value. CONCLUSION Our data suggest that visual gross examination of the uterus provides safe and reliable estimates of both myometrial invasion and cervical infiltration. So, the surgeon can rely on the procedure to decide the need for further operative manipulations.

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
OBJECTIVE To assess the accuracy of intra-operative frozen section reports at identifying the features of high risk uterine disease compared with final histopathology. DESIGN Retrospective study. METHODS The records of 460 patients with uterine cancer registered with the Queensland Centre for Gynaecological Cancer between January 1, 1996 and December 31, 1998 were reviewed. Intra-operative frozen section was undertaken in 260 patients with endometrial adenocarcinoma. Frozen section pathology was compared with the final histopathology reports. Inter-observer reliability was assessed using percentage agreement and kappa statistics. Clinical notes were also reviewed to determine if errors resulted in sub-optimal patient care. RESULTS Respectively, tumour grade and depth of myometrial invasion were accurately reported in 88.6% of cases (expected 61.5%, Kappa 0.70) and 94.7% (expected 53.8%, Kappa 0.89). Errors were predominantly attributable to difficulties with respect to the interpretation of tumour grade. The error resulted in the patient receiving sub-optimal surgical management in only 11 cases (5.3%) CONCLUSION Frozen section is accurate at identifying the features of high risk uterine disease in the setting of endometrial cancer and can play an important role in directing primary operative management.

Abstract
This review article summarizes and comments the role of magnetic resonance imaging (MRI) in the management of endometrial cancer. The MRI technique, appearance, and diagnostic criteria of endometrial carcinoma are discussed. The value of MRI in the preoperative staging of endometrial cancer is compared to alternative strategies. Contrast-enhanced MRI performs best in the pretreatment evaluation of myometrial or cervical invasion, compared to ultrasonography (US), computed tomography (CT), or nonenhanced MRI. The overall costs and accuracy are similar to those of the current methods of staging, including intraoperative gross dissection of the uterus. In addition, results of MRI might decrease the number of unnecessary lymph node dissections. J. Magn. Reson. Imaging 2001;13:850-855.

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.

Abstract
PURPOSE To determine if, in a patient with an endometrial cancer, in addition to the knowledge of tumor grade, preoperative magnetic resonance (MR) imaging findings contribute to treatment stratification and specialist referral. MATERIALS AND METHODS By using a MEDLINE literature search and institutional pathology reports, pretest probabilities for myometrial invasion were correlated with tumor grade. Likelihood ratios (LRs) were obtained through summary receiver operating characteristics. RESULTS The mean pretest probabilities of deep myometrial invasion were derived from seven articles (1,875 patients) and from 125 institutional pathology reports. LRs for the prediction of myometrial invasion with contrast-enhanced MR imaging were derived from nine studies (742 patients); positive and negative LRs were 10.11 and 0.1, respectively. The mean weighted pretest probabilities of deep myometrial invasion in patients with tumor grades 1, 2, or 3 were 13%, 35%, or 54%, respectively. Posttest probabilities of deep myometrial invasion for grades 1, 2, or 3 increased to 60%, 84%, or 92%, respectively, for positive and decreased to 1%, 5%, or 10%, respectively, for negative MR imaging findings. CONCLUSION Use of contrast-enhanced MR imaging significantly affects the posttest probability of deep myometrial invasion in patients with all grades of endometrial cancer and could be used to select patients for specialist referral.

Abstract
We present the largest multicenter study evaluating whether intraoperative visual estimation can accurately assess the depth of myometrial invasion in patients with endometrial cancer. The study population consisted of 403 consecutive women who underwent total hysterectomy for endometrial cancer. After the uterus was removed, a visual estimate of depth of gross myometrial invasion was recorded. The uterus was opened, the endometrial cavity was inspected, and one or more full-thickness incisions were made through the tumor, myometrium, and serosa. An intraoperative estimation of gross myometrial invasion was made and classified as more or less than 50% of the uterine wall. Gross visual estimation accurately identified the microscopic myometrial invasion in 85.3% (344/403) of cases. Sensitivity, specificity, and positive and negative predictive values of gross estimation in determining a microscopic myometrial invasion greater than 50% were 73.0, 92.5, 85.0, and 85.5%, respectively. Among patients in whom the myometrial invasion was underestimated at gross examination the tumoral invasion was limited to the inner two thirds of the myometrium in 45% (18/40) of cases and the distance from the tumor-myometrial junction to the uterine serosa was greater than 3 mm in 65% (26/40) of cases. We conclude that gross estimation of myometrial invasion is a reliable and inexpensive method for evaluating the invasiveness of uterine carcinomas and that deciding to perform an extensive surgical staging upon gross estimation will be in accordance with the final histopathologic report in about 9 of 10 cases.

Abstract
OBJECTIVE The aim of this study was to analyze the prognostic significance of DNA ploidy in patients with endometrial cancer. METHODS Between October 1988 and January 1997, DNA ploidy was determined prospectively in 208 women who were staged surgically by a standard protocol that included pelvic and para-aortic lymphadenectomy. Median follow-up was 48 months. RESULTS Diploid tumors were identified in 154 (74%) patients and aneuploid tumors in 54 (26%). Patients with aneuploid tumors had a significantly higher prevalence of metastases to the cervix, adnexa, and omentum, malignant pelvic cytology, and advanced surgical stage. Patients with aneuploid tumors had a 4.5 times higher prevalence of pelvic lymph node metastases and a 5.8 times higher prevalence of para-aortic lymph node metastases. A significantly higher proportion of patients with aneuploid tumors was diagnosed with recurrent or progressive endometrial cancer (22.2 versus 6.5%, P = 0.002). Patients with aneuploid tumors had a significantly lower rate of survival from cancer death (P = 0.038) with 83% versus 94% surviving 5 years. CONCLUSION Patients with aneuploid tumors are at high risk for lymph node metastases and should be surgically staged, including pelvic and para-aortic lymphadenectomy. Aneuploidy confers a risk for endometrial cancer death and these patients should be candidates for clinical trials evaluating treatment following surgery.

Abstract
A trend toward more conservative surgical intervention is evident in the current management of many gynecologic malignancies. The trend to manage vulvar carcinoma has moved away from the standard en bloc radical vulvectomy and bilateral lymphadenectomy and now consists of more limited excision of the primary tumor as well as of the regional lymph nodes. In preinvasive cervical carcinoma, conization is preferred instead of hysterectomy. The possibility for a more conservative surgical approach is also being explored for the treatment of selected early stage and advanced or recurrent cervical carcinomas. Although the primary surgical treatment of endometrial carcinoma remains unchanged, the necessity to perform (in all cases) the more extensive procedure required for staging purposes is being challenged. In early stage borderline ovarian tumors, not only adnexectomy but cystectomy alone is considered acceptable and reexploration for staging purposes may be unwarranted. In stage IA invasive carcinoma, adnexectomy of the involved side only is probably also sufficient. In advanced ovarian carcinoma, the more aggressive cytoreduction involving multiple organ resection is being restrained. Secondary debulking is performed only on a selective basis and the routine performance of second-look laparotomy has been given up.

Abstract
BACKGROUND Recent reports indicate that certain pre- and intraoperatively determined risk factors are predictive of pelvic lymph node metastases from endometrial cancer, allowing selective pelvic lymph node dissection. The objective of this study was to evaluate the accuracy of pre-, pre-/intra- and postoperatively determined tumor characteristics. METHODS The study is based on 100 patients treated from 1987-1991 with total abdominal hysterectomy and bilateral salpingo-oophorectomy. In all patients thorough pelvic lymphadenectomies were performed (no sampling). These patients were evaluated according to different macroscopic and histologic tumor characteristics retrospectively in a blind fashion (the lymph node status was later determined separately). Multivariate analysis was applied and the results were compared using receiver operator characteristic curves. In 15 of 100 patients, pelvic lymph node metastases could be histologically demonstrated. RESULTS Multivariate analysis of 22 tumor characteristics identified the following as being independent in relation to pelvic lymph node metastases: preoperatively determined characteristics: serous papillary tumor type, invasion of myometrium, and histologic grade (Christopherson); pre-/intraoperatively: serous papillary type, histologic grade (Christopherson), and cervical involvement; and postoperatively: lymphangiosis carcinomatosa and hemangiosis carcinomatosa. Receiver operator characteristic curves show that for pelvic node metastases the postoperatively determined histologic findings are more predictive than all other factors that can be evaluated pre- and/or intraoperatively. CONCLUSION Pre- and intraoperative tumor characteristics can determine the individual risk for pelvic lymph node involvement, but additional studies addressing the therapeutic value of pelvic lymphadenectomy would be necessary to define a probability threshold for lymphadenectomy in a decision analysis.

Abstract
OBJECTIVES The purpose of our study was to determine if frozen section accurately identifies certain poor prognostic pathologic factors in endometrial carcinoma that are known to be associated with pelvic and paraaortic nodal metastasis, including deep myometrial invasion, poorly differentiated tumor, cervical invasion, adnexal involvement, and poor histologic type. STUDY DESIGN The frozen-section pathologic results of 199 patients with clinical stage I and II endometrial cancer were retrospectively compared with permanent-section pathologic findings. RESULTS The depth of myometrial invasion (superficial third vs deep two thirds) was accurately determined by frozen-section diagnosis at surgery in 181 of 199 cases (91.0%). The sensitivity of frozen-section diagnosis for deep myometrial invasion was 82.7%, and the specificity was 89.1%. The following tumor characteristics were accurately determined on frozen section at surgery: poorly differentiated tumor (95.0%), cervical invasion (94.0%), adnexal involvement (98.5%), and histologic type (94.0%). Frozen section underestimated deep myometrial invasion in 17.3% of patients with this characteristic and poorly differentiated tumor in 26.3% when compared with permanent-section diagnosis. In patients with unfavorable histologic types, papillary serous and adenosquamous carcinomas were the most commonly misdiagnosed histologic types by frozen section at surgery (70.6%). However, when the preoperative curettage pathologic findings were included, these inaccuracies in tumor grade and histologic type dropped to 15.8% and 35.3%, respectively. Only 13 of 199 patients (6.5%) were not correctly identified by frozen section at surgery as having poor prognostic pathologic features. CONCLUSION Frozen section diagnosis at surgery is an important procedure that enables the surgeon to identify patients at high risk for pelvic and paraaortic nodal metastasis.

Abstract
A distinct type of cervical involvement by endometrial cancer is reported and termed cervical implantation metastasis. It is believed to result from implantation of endometrial cancer on the denuded endocervix after fractional dilatation and curettage (D & C). The histologic criteria for diagnosis are: (1) the cervical implantation metastasis must be imbedded in the endocervical epithelium or superficial stroma surrounded by an implantation site of inflammatory cells and granulation tissue (free-floating cancer cells above the cervical mucosa are not acceptable as implantation tissue), (2) the histologic findings of the cervical implantation metastasis must be similar to those of the endometrial adenocarcinoma in the uterine corpus, (3) the cervical implantation metastasis must be separate from the primary tumor with no evidence of direct extension, and (4) the cervical implantation metastasis should be surrounded by nonneoplastic endocervical glands with no transition between the two. Of the 176 patients who underwent fractional D & C before hysterectomy, nine (5%) were found to have cervical implantation metastasis. No patients had cervical implantation metastasis who did not undergo fractional D & C before hysterectomy. When stratified according to stage, grade, and myometrial invasion, there was no statistically significant difference in the recurrence rate between patients with or without cervical implantation metastasis. It appears that cervical implantation metastasis does not alter prognosis or require specific treatment.

Abstract
The purpose of this study was to evaluate the ability of the pathologist to assess intraoperatively the hysterectomy specimen in patients with endometrial carcinoma. The past few years have seen the definition of prognostic variables that predict the ultimate outcome of patients with endometrial carcinoma. As a result, the International Federation of Gynecology and Obstetrics (FIGO) revised the staging system to take into account such prognostic factors as grade, depth of myometrial penetration by tumor, cervical involvement, adnexal metastasis, peritoneal cytology, and involvement of pelvic and para-aortic lymph nodes. The need for node evaluation has led to considerable controversy as to whether all hysterectomies for Stage I disease should be performed by gynecologic oncologists. To help predict which patients will need node sampling, several published studies have shown that determination of depth of myometrial penetration can be accomplished by gross evaluation of the uterine specimen, and even more accurately on frozen section. These studies recorded excellent results, but were limited to evaluation by pathologists with specific expertise in gynecologic pathology. The current study evaluated the ability to assess tumor grade, depth of invasion, and presence of cervical invasion by intra-operative evaluation of sixty hysterectomy specimens from patients with clinical Stage I disease. The gross and frozen section reports used for this study were produced by anatomic pathologists ranging in experience level from lecturer to professor, with varying levels of experience in gynecologic pathology. Our results indicate that the level of experience of the pathologist does not affect the ability to accurately assess the specimen for the parameters described. This, in turn, allows the surgeon to correctly determine the need for lymph node sampling in 94% of cases.

Abstract
Surgical staging documented extrauterine disease in 27.9% of 168 patients with apparent early-clinical-stage uterine cancer. An analysis of operative time (78 +/- 21 min), blood loss (332 +/- 160 cc), and surgical site infection risks (4.7%) indicated little additional risk of lymphadenectomy. The long-term risk of lymphocyst (1.3%) or lymphedema (0.7%) was small. The histologic information obtained from staging was utilized to rationally guide the need for adjunctive teletherapy. The overall risk of recurrence (median follow-up, 26 months) with surgical Stage I disease was 2.6%.

Abstract
Prognostic risk factors were statistically analyzed from the histopathologic data obtained from 90 Japanese women with stages I and II endometrial carcinoma treated surgically, including systemic retroperitoneal lymph node dissection, between June 1979 and June 1989. In stage Ia endometrial carcinoma, pelvic and paraaortic nodes metastasis were seen in 13.8(4/29)% and 0.0(0/19)% of patients, respectively. In stage Ib, the incidence of pelvic and paraaortic node metastasis was 25.6(11/43)% and 9.7(3/31)%, respectively. In stage II, the incidence was 38.9(7/18)% and 13.3(2/15)%, respectively. Prognosis of patients even with deep myometrial invasion (greater than or equal to 2/3) or G3 tumor was fairly good (5-year survival rate: 87.5% and 85.7%, respectively) if the disease was histologically confined to the uterine corpus. Once the tumor spread outside the corpus uteri, the survival rate of patients was strongly affected by the grade of the tumor, moderate to marked lymph-vascular space invasion of tumor cells, or tumor invading middle or outer third of myometrium (P less than 0.05 for each factor). In summary, endometrial cancer frequently metastasize to pelvic and paraaortic lymph nodes even in the early stages, and lymph node metastasis and other extracorporeal spread of disease have a serious impact on patient survival. Prognosis of patients with extracorporeal spread of disease seems to be determined by the high grade of tumor and lymph-vascular space invasion. These results suggest that surgical exploration including paraaortic lymph node dissection to accurately evaluate the extent of the disease is essential to estimate the patient's prognostic risk and to individualize the treatment schedule.

Abstract
The prognostic significance of the extent of cervical involvement by endometrial cancer is impossible to determine from the literature because previous reports have included fractional dilatation and curettage for staging, preoperative radiotherapy, and surgical stage III and IV disease. Therefore, we reviewed and restaged according to the new FIGO system all patients with endometrial cancer from January 1981 to December 1989. Of 180 patients undergoing hysterectomy for endometrial cancer, 20 had surgical stage II disease. No patient received preoperative radiotherapy. None of 12 patients (0%) with stage IIA disease developed recurrence, while 5 of 8 (63%) with stage IIB disease recurred (P less than 0.01). All 5 recurrences were in extrapelvic sites. Endocervical stroma invasion appears to import a statistically significant worse prognosis than endometrial glandular involvement.
