Abstract
Introduction Accurate surgical staging is an essential component in the management of carcinoma endometrium to assess the stage of disease and to tailor adjuvant treatment. Sentinel node technique was introduced as an alternative for extensive lymphadenectomy in early stages to avoid complications associated with lymphadenectomy. Aims and Objectives To assess the detection rate and diagnostic accuracy of SLN mapping in patients with early-stage carcinoma endometrium. Materials and Methods Prospective validation study involving 30 patients diagnosed to have early-stage carcinoma endometrium. Sentinel nodes were detected by combined methods of radio colloid dye and isosulphan blue dye injection. Results Sentinel lymph node was detected in 19 patients (63.4%). 11 patients had no sentinel nodes. Total number of sentinel nodes isolated was 68 with a mean of 2.26 per patient (range 0-4). Ten (33.33%) patients had single sentinel node location, while 9 (30%) had more than 1 sentinel lymph nodes. Twelve patients had bilateral sentinel nodes, and the most frequent location of sentinel node was obturator, 19 (63.3%) especially on right hemi-pelvis. One patient had a hot para-aortic node, while none had blue para-aortic sentinel node. Average number of lymph nodes obtained by lymphadenectomy was 13 per patient (range 7-22). All patients with sentinel node had negative frozen report as well as in histopathology. Two patients in whom no sentinel nodes were detected by either techniques had metastatic nodes in histopathology report. Conclusion Detection rate was maximum with radiocolloid dye, and it is better to utilize the technique for less graded tumours and endometrioid variants.

Abstract
OBJECTIVE To evaluate factors impacting survival outcomes in patients with uterine serous carcinoma (USC). METHODS Data of consecutive patients diagnosed with USC undergoing surgery between 2000 and 2020 at Fondazione IRCCS Istituto Nazionale Tumori of Milan (Italy) were reviewed. Progression-free (PFS) and overall survival (OS) outcomes were evaluated using Kaplan-Meier and Cox proportional hazard models. RESULTS Records of 147 consecutive patients meeting the inclusion criteria were analyzed. Stage distribution was: 67 (45.6%) patients with early-stage with uterine confined disease and 80 (54.4%) with advanced stages disease. Minimally invasive surgery was performed in 43 patients (29.5%). The median follow-up period was 78.6 months (IQ range = 35.7-117.3 months). The overall recurrence rate was 41% (60 patients): 19/67 patients (28.4%) with early-stage disease and 41/80 patients (51.3%) with advanced stage. The 5-year PFS rate was 35.0% (95% confidence interval [CI]: 27.5-44.7%). In multivariate analysis, age, BMI, depth of myometrial invasion, cytology, and optimal cytoreduction with postoperative residual tumor absent significantly impacted on PFS. The 5-year OS rates were 46.5% (95% CI: 38.1-56.8). The result of multivariate analysis showed that there was significant difference in OS based only on optimal cytoreduction and accuracy of retroperitoneal surgery. CONCLUSIONS In apparent early-stage USC, peritoneal and retroperitoneal staging allows to identify patients with disease harboring outside the uterus. Optimal cytoreduction is the most significant prognostic factor. Further collaborative studies are warranted in order to improve outcomes of USC patients.

Abstract
BACKGROUND Pelvic lymphadenectomy provides prognostic information for those diagnosed with endometrial (womb) cancer and provides information that may influence decisions regarding adjuvant treatment. However, studies have not shown a therapeutic benefit, and lymphadenectomy causes significant morbidity. The technique of sentinel lymph node biopsy (SLNB), allows the first draining node from a cancer to be identified and examined histologically for involvement with cancer cells. SLNB is commonly used in other cancers, including breast and vulval cancer. Different tracers, including colloid labelled with radioactive technetium-99, blue dyes, e.g. patent or methylene blue, and near infra-red fluorescent dyes, e.g. indocyanine green (ICG), have been used singly or in combination for detection of sentinel lymph nodes (SLN). OBJECTIVES To assess the diagnostic accuracy of sentinel lymph node biopsy (SLNB) in the identification of pelvic lymph node involvement in women with endometrial cancer, presumed to be at an early stage prior to surgery, including consideration of the detection rate. SEARCH METHODS We searched MEDLINE (1946 to July 2019), Embase (1974 to July 2019) and the relevant Cochrane trial registers. SELECTION CRITERIA We included studies that evaluated the diagnostic accuracy of tracers for SLN assessment (involving the identification of a SLN plus histological examination) against a reference standard of histological examination of removed pelvic +/- para-aortic lymph nodes following systematic pelvic +/- para-aortic lymphadenectomy (PLND/PPALND) in women with endometrial cancer, where there were sufficient data for the construction of two-by-two tables. DATA COLLECTION AND ANALYSIS Two review authors (a combination of HN, JM, NW, RG, and WH) independently screened titles and abstracts for relevance, classified studies for inclusion/exclusion and extracted data. We assessed the methodological quality of studies using the QUADAS-2 tool. We calculated the detection rate as the arithmetic mean of the total number of SLNs detected out of the total number of women included in the included studies with the woman as the unit of analysis, used univariate meta-analytical methods to estimate pooled sensitivity estimates, and summarised the results using GRADE. MAIN RESULTS The search revealed 6259 unique records after removal of duplicates. After screening 232 studies in full text, we found 73 potentially includable records (for 52 studies), although we were only able to extract 2x2 table data for 33 studies, including 2237 women (46 records) for inclusion in the review, despite writing to trial authors for additional information. We found 11 studies that analysed results for blue dye alone, four studies for technetium-99m alone, 12 studies that used a combination of blue dye and technetium-99m, nine studies that used indocyanine green (ICG) and near infra-red immunofluorescence, and one study that used a combination of ICG and technetium-99m. Overall, the methodological reporting in most of the studies was poor, which resulted in a very large proportion of 'unclear risk of bias' ratings. Overall, the mean SLN detection rate was 86.9% (95% CI 82.9% to 90.8%; 2237 women; 33 studies; moderate-certainty evidence). In studies that reported bilateral detection the mean rate was 65.4% (95% CI 57.8% to 73.0%) . When considered according to which tracer was used, the SLN detection rate ranged from 77.8% (95% CI 70.0% to 85.6%) for blue dye alone (559 women; 11 studies; low-certainty evidence) to 100% for ICG and technetium-99m (32 women; 1 study; very low-certainty evidence). The rates of positive lymph nodes ranged from 5.2% to 34.4% with a mean of 20.1% (95% CI 17.7% to 22.3%). The pooled sensitivity of SLNB was 91.8% (95% CI 86.5% to 95.1%; total 2237 women, of whom 409 had SLN involvement; moderate-certainty evidence). The sensitivity for of SLNB for the different tracers were: blue dye alone 95.2% (95% CI 77.2% to 99.2%; 559 women; 11 studies; low-certainty evidence); Technetium-99m alone 90.5% (95% CI 67.7% to 97.7%; 257 women; 4 studies; low-certainty evidence); technetium-99m and blue dye 91.9% (95% CI 74.4% to 97.8%; 548 women; 12 studies; low-certainty evidence); ICG alone 92.5% (95% CI 81.8% to 97.1%; 953 women; 9 studies; moderate-certainty evidence); ICG and blue dye 90.5% (95% CI 63.2.6% to 98.1%; 215 women; 2 studies; low-certainty evidence); and ICG and technetium-99m 100% (95% CI 63% to 100%; 32 women; 1 study; very low-certainty evidence). Meta-regression analyses found that the sensitivities did not differ between the different tracers used, between studies with a majority of women with FIGO stage 1A versus 1B or above; between studies assessing the pelvic lymph node basin alone versus the pelvic and para-aortic lymph node basin; or between studies that used subserosal alone versus subserosal and cervical injection. It should be noted that a false-positive result cannot occur, as the histological examination of the SLN is unchanged by the results from any additional nodes removed at systematic lymphadenectomy. AUTHORS' CONCLUSIONS The diagnostic test accuracy for SLNB using either ICG alone or a combination of a dye (blue or ICG) and technetium-99m is probably good, with high sensitivity, where a SLN could be detected. Detection rates with ICG or a combination of dye (ICG or blue) and technetium-99m may be higher. The value of a SLNB approach in a treatment pathway, over adjuvant treatment decisions based on uterine factors and molecular profiling, requires examination in a high-quality intervention study.

Abstract
Endometrial cancer (EC) is the most common gynecological neoplasm in developed countries. In literature, there are discordant data regarding the therapeutic value of systematic lymphadenectomy whereas the importance of lymph node status for determining prognosis and the need for adjuvant treatment is undoubted. Given the low risk of lymph-node metastases in the apparent early-stage disease and the significant surgical and postoperative risks when performing a complete pelvic lymphadenectomy, the surgical approach in these patients is controversial, ranging from no nodal evaluation to comprehensive pelvic and aortic lymphadenectomy. The recent introduction of sentinel node mapping represents the mid-way between the execution and omission of node dissection in EC patients. Indeed, the sentinel node mapping has rapidly emerged as an alternative to complete lymphadenectomy to reduce morbidity. In the present review, we discuss the role of sentinel node mapping in the surgical management of EC evaluating all aspects of this procedure.

Abstract
AIM During the last years, the role of sentinel lymph node mapping (SLNM) for endometrial cancer (EC) surgical treatment has increased in popularity. However, several controversies remain about different technical steps of SLNM. Thus, a randomised control trial was designed to compare cervical (CI) and hysteroscopic (HI) indocyanine green (ICG) injection for SLNM of newly diagnosed EC undergoing surgical staging. The primary end-point of the study was to compare these two techniques in terms of para-aortic detection rate. METHODS Patients with apparent stage I or II histologically confirmed EC undergoing surgery were included in the study. This randomised trial distinguished patients in two study groups according to two different techniques of ICG SLNM: CI versus HI injection. Patients who met the inclusion criteria were randomly assigned to CI or HI injection in a 1:1 ratio. The central randomisation system allocated patient randomisation numbers sequentially in the order in which the patients were enrolled. This randomised trial was not blinded for either patients or the surgeons. RESULTS From March 2017 until April 2019, a total of 165 patients were randomised in this study: 85 (51.5%) in the CI group and 80 (48.5%) in the HI group. After randomisation, 14 (8.5%) patients were excluded from the study. Finally, 151 patients were included in the analysis: 82 (54.3%) in the CI group and 69 (45.7%) in the HI group. Hysteroscopy injection shows an ability to detect Sentinel nodes (SNLs) in the para-aortic area of about 10% greater compared with CI injection, although this difference did not reach statistical significance. The HI technique was superior in detecting isolated para-aortic SLNs (5.8% Versus 0%). The CI injection was correlated with higher SLN detection rates at the pelvic level compared with HI injection. Pelvic and overall detection was higher in the CI group. CONCLUSIONS The present study supports the adoption of CI instead of HI injection because the former allows better identification of sentinel nodes (especially in the pelvic area). Detection of SLN in the para-aortic area was slightly higher in patients receiving a HI injection, but the difference with the CI route was not statistically significant.

Abstract
OBJECTIVE To report on the performance of hysteroscopic injection of tracers (indocyanine green (ICG) and technetium-99m (Tc-99m)) for sentinel lymph node (SLN) mapping in endometrial cancer. METHODS Single-center retrospective evaluation of consecutive patients who underwent SLN mapping following hysteroscopic peritumoral injection of tracer. Detection rate (overall/bilateral/aortic) diagnostic accuracy, and oncologic outcomes were evaluated. RESULTS A total of 221 procedures met the inclusion criteria. Mean patient age was 60 (range 28-84) years and mean body mass index was 26.9 (range 15-47) kg/m2 . In 164 cases (70.9%) mapping was performed laparoscopically. The overall detection rate of the technique was 94.1% (208/221 patients). Bilateral pelvic mapping was found in 62.5% of cases with at least one SLN detected and was more frequent using ICG than with Tc-99m (73.8% vs 53.3%; p<0.001). In 47.6% of cases SLNs mapped in both pelvic and aortic nodes, and in five cases (2.4%) only in the aortic area. In eight patients (3.8%) SLNs were found in aberrant (parametrial/presacral) areas. Mean number of detected SLNs was 3.7 (range 1-8). In 51.9% of cases at least one node other than SLNs was removed. Twenty-six patients (12.5%) had nodal involvement: 12 (46.2%) macrometastases, six (23.1%) micrometastases, and eight (30.7%) isolated tumor cells. In 12 cases (46.8%) the aortic area was involved. Overall, 6/221 (2.7%) patients had isolated para-aortic nodes. Three false-negative results were found, all in the Tc-99m group. All had isolated aortic metastases. Overall sensitivity was 88.5% (95% CI 71.7 to 100.0) and overall negative predictive value was 96.5% (95% CI 86.8 to 100.0). There were 10 (4.8%) recurrences: five abdominal/distant, four vaginal, and one nodal (in the aortic area following a unilateral mapping plus side-specific pelvic lymphadenectomy). Most recurrences (9/10 cases) were patients in whom a completion lymphadenectomy was performed. No deaths were reported after a mean follow-up of 47.7 months. CONCLUSIONS Hysteroscopic injection of tracers for SLN mapping in endometrial cancer is as accurate as cervical injection with a higher detection rate in the aortic area. ICG improves the bilateral detection rate. Adding lymphadenectomy to SLN mapping does not reduce the risk of relapse.

Value and best way for detection of Sentinel lymph node in early stage endometrial cancer: Selective lymphadenectomy algorithm. Eur J Obstet Gynecol Reprod Biol 2018; 225:35-39. [PMID: 29660577 DOI: 10.1016/j.ejogrb.2018.03.042] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/26/2017] [Revised: 03/14/2018] [Accepted: 03/22/2018] [Indexed: 11/22/2022]
Abstract
INTRODUCTION The cornerstone of treatment for endometrial carcinoma is total abdominal hysterectomy and bilateral salpingo-oophoprectomy. Pelvic lymphadenectomy, with or without para-aortic lymphadenectomy, plays an important role in the surgical staging of endometrial carcinoma, and provides more accurate prognostic information. AIMS We aimed to evaluate the value and techniques for SLN mapping in early stage endometrial cancer with low risk for lymph node metastasis and whether selective or systematic lymphadenectomy is needed according to the results of proposed algorithm. METHOD Between June 2016 and June 2017, 120 patients with early stage endometrial cancer with low risk for nodal metastasis underwent surgical staging. Patients were classified equally according to SLN mapping technique used for injecting the methylene blue dye. Group A included hysteroscopic guided methylene blue injection, Group B included transcervical injection, Group C included subserosal uterine injection and Group D included combined transcervical and subserosal injection. Blue lymph nodes and enlarged suspicious whether stained or non stained ones were dissected for frozen section evaluation done then bilateral pelvic node dissection was done and tissues were sent for pathological examination. RESULTS Clinical and pathological SLN detection were more with hysteroscopic technique than others and pathological detection was lower than clinical detection in all techniques. Metastatic disease was more common in nodes with suspicious appearance. About 10% of negative suspicious and mapped nodes were associated with positive other nodes for metastasis. CONCLUSION SLN in endometrial cancer has a role in staging of endometrial cancer with best technique for detection, hysteroscopic guided blue dye injection. SLN can be used in patients with low risk for lymph node metastasis for selective lymphadenectomy. Blue dye labelling using methylene blue dye is good in low resource countries as it is cheap. We recommended the following algorithm for surgical staging in early endometrial cancer with better results than using SLN alone. Stage I type 1, grade 1,2 endometrial cancer should undergo surgical staging with initial evaluation of the peritoneum which if affected, it is stage III with no need for lymphadenectomy. Then, dissection of the blue and suspicious nodes which if any is positive on frozen section, selective same side pelvic and paraaortic nodal dissection should be done. If they are negative, no need for lymphadenectomy. This approach can help patients to avoid the side effects associated with a complete lymphadenectomy. The higher rate of detection using this algorithm is related to combining the suspicions nodes with the stained ones.

Abstract
OBJECTIVES To analyze detection-rate(DR) and diagnostic-accuracy (A) of sentinel-nodes(SLNs) mapping following hysteroscopic-injection of tracer. To compare DR and A between tracers: ICG and Tc99m. METHODS Evaluation of endometrial-cancer patients who underwent SLNs mapping after hysteroscopic-peritumoral-injection of tracer±lymphadenectomy. Analysis of DR (overall-bilateral-aortic) and A in the entire cohort and comparison between tracers. RESULTS 202 procedures were performed from January/2005 to February/2017. Mean age:60years (28-82); mean BMI: 26.8 kg/m2 (15-47). In 133 cases (65.8%) hysterectomy and mapping procedure were performed laparoscopically. The overall-DR of the technique was 93.2% (179/192) (10 cases were excluded: 9 for technical-equipment failure; 1 for vagal reaction). Bilateral pelvic mapping was found in 59.7% of cases (107/179) and was more frequent in the ICG group (72.8% vs 53.3%; p: 0.012). In 50.8% of cases (91/179) SLNs were mapped both in pelvic and aortic nodes, and in 5 cases (2.8%) only in the aortic area. The mean number of detected SLNs was 3.7 (1-8). 22 patients (12.3%) had nodal involvement: 10-(45.5%)-macrometastases; 5-(22.7%)-micrometastases; 7-(31.8%)-ITCs. In 6 cases (27.3%) only aortic nodes were positive; in 5 cases (22.7%) both pelvic and aortic nodes and in 11 cases (50%) only pelvic nodes were involved. Three false-negative results were found, all in the Tc99m group. All had isolated aortic metastases with negative pelvic nodes. Overall-sensitivity was 86.4% (95%CI: 68.4-100) and overall-negative-predictive-value (NPV) was 96.4% (95%CI 86.7-100). No differences in terms of overall-DR, overall-sensitivity and overall-NPV were found between the two tracers. CONCLUSIONS Hysteroscopic-injection of tracer for SLNs mapping in endometrial cancer is as accurate as cervical injection with a higher DR in the aortic area. ICG improves bilateral-DR. Further investigation is warranted on this topic.

Abstract
BACKGROUND In the staging of endometrial cancer, controversy remains regarding the role of sentinel lymph node mapping compared with other nodal assessment strategies. OBJECTIVE We conducted a systematic review to evaluate the diagnostic accuracy and clinical impact of sentinel lymph node mapping in the management of endometrial cancer. DATA SOURCES We searched Medline, Embase, and the Cochrane Central Registry of Controlled trials for studies published in English before March 25, 2016 (PROSPERO CRD42016036503). STUDY ELIGIBILITY CRITERIA Studies were included if they contained 10 or more women with endometrial cancer and reported on the detection rate, sensitivity, and/or impact on treatment or survival of sentinel lymph node mapping. STUDY APPRAISAL AND SYNTHESIS METHODS Two authors independently reviewed abstracts and full-text articles for inclusion and assessed study quality. The detection rate, sensitivity, and factors associated with successful mapping (study size, body mass index, tumor histology and grade, injection site, dye type) were synthesized through random-effects meta-analyses and meta-regression. RESULTS We identified 55 eligible studies, which included 4915 women. The overall detection rate of sentinel lymph node mapping was 81% (95% confidence interval, 77-84) with a 50% (95% confidence interval, 44-56) bilateral pelvic node detection rate and 17% (95% confidence interval, 11-23) paraaortic detection rate. There was no difference in detection rates by patient body mass index or tumor histology and grade. Use of indocyanine green increased the bilateral detection rate compared with blue dye. Additionally, cervical injection increased the bilateral sentinel lymph node detection rate but decreased the paraaortic detection rate compared with alternative injection techniques. Intraoperative sentinel lymph node frozen section increased the overall and bilateral detection rates. The sensitivity of sentinel node mapping to detect metastases was 96% (95% confidence interval, 91-98); ultrastaging did not improve sensitivity. Compared with women staged with complete lymphadenectomy, women staged with sentinel lymph node mapping were more likely to receive adjuvant treatment. CONCLUSION Sentinel lymph node mapping is feasible and accurately predicts nodal status in women with endometrial cancer. The current data favors the use of cervical injection techniques with indocyanine green. Sentinel lymph mapping may be considered an alternative standard of care in the staging of women with endometrial cancer.

Abstract
BACKGROUND Endometrial carcinoma is the most common gynecological cancer and its treatment is still controversial, especially in its early stages. There are conflicting data about the efficacy of retroperitoneal lymphadenectomy during abdominal hysterectomy and bilateral salpingoophrectomy treatment. Lymphadenectomy carries a risk of severe complications, especially in women with co-morbidities. Selective lymphadenectomy has been widely employed for staging evaluation of endometrial carcinoma because it is simple and seems to provide reliable data regarding nodal metastasis. This study was designed to evaluate accuracy of sentinel node sampling in detecting lymph node metastasis in primary endometrial carcinoma during staging laparotomy. MATERIALS AND METHODS Ninety-three women with endometrial carcinoma at high-risk for nodal metastasis were studied. During laparotomy, methylene blue dye was injected into sub-serosal myometrium, then retroperitoneal spaces were opened and blue lymph nodes within pelvic and para-aortic regions were removed as separate specimens for histopathological examination (sentinel lymph nodes=SLNs). Hysterectomy and selective lymphadenectomy then performed for all women included in this study. RESULTS Deposition of methylene dye into at least one lymph node was observed in 73.1% (68/93) of studied cases. 18.3% (17/93) of studied women had positive lymph node metastasis and 94.1% (16/17) of them had positive metastasis in SLNs. In this study, SNLs had 94.4% sensitivity and 100% specificity in prediction of lymph node metastasis. Mean number of lymph nodes removed from each case decreased when SLNs biopsy were taken. CONCLUSIONS SLNs are the key lymph nodes in endometrial tumor metastasis and their involvement could be an indicator for whether or not complete systematic lymphadenectomy is needed during staging laparotomy.

Abstract
OBJECTIVES Sentinel lymph node biopsy (SLNB) can identify patients with nodal metastases who are eligible for tailored treatment. The aim of study was to compare the SLN detection rates using cervical and subserosal administration of 2 tracers. RESULTS In group 1 (82 patients), SLNB was performed using radiocolloid injected to the cervix and blue dye administered to the fundus. In group 2, blue dye was injected to cervix and fundus (106 patients). Only SLNB was performed in 128 (68.1%) women. In the remaining 60 (31.9%) patients, pelvic/para-aortic lymphadenectomy together with SLNB was performed. Groups 1 and 2 did not differ with regard to the frequencies of SLNB and lymphadenectomy. The detection rate for both groups was 90.9%. Bilateral detection was achieved in 72.5%. Para-aortic SLNs were found in 9.6%. Detection rates in groups 1 and 2 were 95.1% and 87.7% (P = 0.065). In comparison of cervical administration of radioisotope and subserosal injection of blue dye in group 1, we found a significant difference for total SLN detection (91.5% vs 74.4%, P < 0.05) and no significant difference for bilateral detection (73.3% vs 59.1%, P = 0.776). We did not find differences in the para-aortic SLN detection rates achieved after administration of a radiotracer and injection of a blue dye (4.9% vs 9.8%, P = 0.184). Eighteen patients (9.6%) presented with nodal disease, including 15 women with SLN involvement. The false-negative rate, calculated for patients subjected to lymphadenectomy, was 12.5% (1/8); using the SLNB surgical algorithm, it was 10% (1/10). CONCLUSIONS Cervical administration of a tracer, especially radioisotope, results in high SLN detection rates. In turn, the subserosal injection can be used only as an adjuvant method for SLNB. Low para-aortic SLN detection rates observed after cervical administration of a tracer do not seem to be a serious limitation of this technique.

Abstract
BACKGROUND AND OBJECTIVES Endometrial cancer (EC) has an increasing incidence worldwide. Despite the unequivocal prognostic importance of nodal status, systematic lymphadenectomy is associated to elevated morbidity. Sentinel lymph node (SLN) biopsy is designed to avoid extensive nodal dissection and provide crucial oncologic information. The goal of this prospective study was to determine the feasibility, safety, and accuracy of laparoscopic SLN biopsy in EC obtained through hysteroscopic injection of technetium-99 (Tc-99). METHODS From January 2008 to December 2012, a total of 42 women with EC were included in the study. We injected 20 mBq of Tc-99 hysteroscopically underneath the tumor minutes before definitive surgery. Thereafter, laparoscopic SLN identification /biopsy followed by pelvic and para-aortic lymphadenectomy, hysterectomy, and bilateral salpingo-oophorectomy were executed. RESULTS The total number of removed nodes was 970. The detection rate of the method was 73% (31/42). Among the 70 isolated SLNs, 35% (24) were exclusively identified in the para-aortic area. Fourteen patients (45%) had SLN only in the pelvic region, whereas 11 (35%) had SLN in both pelvic and para-aortic areas and 6 women (20%) had isolated para-aortic SNL. Nodal metastases were histologically confirmed in 9 patients (22%), and SLN was identified in 7 of 9 patients (78%). Although the obtained specificity was 100% and the negative predictive value was 89%, the sensitivity was only 58% (false-negative rate of 42%). CONCLUSIONS We could demonstrate that endoscopic SLN biopsy obtained through hysteroscopic injection of Tc-99 is a feasible and safe method. Despite the restricted number of included patients in this series, the obtained sensitivity and false-negative rates raise some questions about the real accuracy of the procedure in EC. Larger validation trials requiring quality pelvic and para-aortic lymphadenectomy are essential to correctly evaluate the method.

Abstract
Endometrial cancer is the most common gynecologic malignancy in the developed countries. Although the high incidence of this occurrence no consensus, about the role of retroperitoneal staging, still exists. Growing evidence support the safety and efficacy of sentinel lymph node mapping. This technique is emerging as a new standard for endometrial cancer staging procedures. In the present paper, we discuss the role of sentinel lymph node mapping in endometrial cancer, highlighting the most controversies features.

Abstract
Herein is presented a technique for minimally invasive sentinel node mapping. The patient had apparently early stage endometrial cancer. Sentinel node mapping was performed using a hysteroscopic injection of indocyanine green followed by laparoscopic sentinel node detection via near-infrared fluorescence. This technique ensures delineation of lymphatic drainage from the tumor area, thus achieving accurate detection of sentinel nodes.

Abstract
In the last few years technical improvements have produced a dramatic shift from traditional open surgery towards a minimally invasive approach for the management of early endometrial cancer. Advancement in minimally invasive surgical approaches has allowed extensive staging procedures to be performed with significantly reduced patient morbidity. Debate is ongoing regarding the choice of a minimally invasive approach that has the most effective benefit for the patients, the surgeon, and the healthcare system as a whole. Surgical treatment of women with presumed early endometrial cancer should take into account the features of endometrial disease and the general surgical risk of the patient. Women with endometrial cancer are often aged, obese, and with cardiovascular and metabolic comorbidities that increase the risk of peri-operative complications, so it is important to tailor the extent and the radicalness of surgery in order to decrease morbidity and mortality potentially derivable from unnecessary procedures. In this regard women with negative nodes derive no benefit from unnecessary lymphadenectomy, but may develop short- and long-term morbidity related to this procedure. Preoperative and intraoperative techniques could be critical tools for tailoring the extent and the radicalness of surgery in the management of women with presumed early endometrial cancer. In this review we will discuss updates in surgical management of early endometrial cancer and also the role of preoperative and intraoperative evaluation of lymph node status in influencing surgical options, with the aim of proposing a management algorithm based on the literature and our experience.

Abstract
Endometrial cancer is increasingly common in affluent Western countries, largely owing to the growing obesity of those populations. There are two recognized types of endometrial cancer: Type I is more common and is associated with obese postmenopausal women and comprises approximately 80% of all endometrial cancers; Type II describes a woman who is often younger and thinner with a more aggressive histologic type that is nonestrogen dependent, of either serous or clear cell histology, and consists of a more aggressive clinical course and results in poorer prognosis. As the majority of patients with endometrial cancer present with symptoms and have early disease, screening is unlikely to be cost effective or reduce the mortality rate. However, surveillance of high-risk populations is a different proposition. Patients who may benefit from routine surveillance include those with a family history of endometrial cancer, a history of hormone replacement therapy with less than 12-14 days of progestogens, long-term use of tamoxifen, hereditary nonpolyposis colorectal cancer family syndrome, Cowden's syndrome, Peutz-Jeghers syndrome, a history of breast cancer and obesity. Most patients with endometrial cancer are offered surgery as first-line therapy. The standard surgical procedure should be an extrafascial total hysterectomy with bilateral salpingo-oophorectomy. Adnexal removal is also recommended, even if the adnexa appear normal, as they may contain micrometastases. The safety of a laparoscopic approach in the surgical management of uterine cancer has not yet been demonstrated in prospective randomized trials, therefore, the field awaits the Gynaecologic Oncology Group's prospective Lap-2 study. While post-treatment follow-up guidelines vary between institutions and countries, in general, patients at high risk of recurrence are followed closely every 3-4 months for the first year or two, then every 6 months to complete 5 years of follow-up.

Abstract
BACKGROUND Retrospective single-centre series have shown the feasibility of sentinel lymph-node (SLN) identification in endometrial cancer. We did a prospective, multicentre cohort study to assess the detection rate and diagnostic accuracy of the SLN procedure in predicting the pathological pelvic-node status in patients with early stage endometrial cancer. METHODS Patients with International Federation of Gynecology and Obstetrics (FIGO) stage I-II endometrial cancer had pelvic SLN assessment via cervical dual injection (with technetium and patent blue), and systematic pelvic-node dissection. All lymph nodes were histopathologically examined and SLNs were serial sectioned and examined by immunochemistry. The primary endpoint was estimation of the negative predictive value (NPV) of sentinel-node biopsy per hemipelvis. This is an ongoing study for which recruitment has ended. The study is registered with ClinicalTrials.gov, number NCT00987051. FINDINGS From July 5, 2007, to Aug 4, 2009, 133 patients were enrolled at nine centres in France. No complications occurred after injection of technetium colloid and no anaphylactic reactions were noted after patent blue injection. No surgical complications were reported during SLN biopsy, including procedures that involved conversion to open surgery. At least one SLN was detected in 111 of the 125 eligible patients. 19 of 111 (17%) had pelvic-lymph-node metastases. Five of 111 patients (5%) had an associated SLN in the para-aortic area. Considering the hemipelvis as the unit of analysis, NPV was 100% (95% CI 95-100) and sensitivity 100% (63-100). Considering the patient as the unit of analysis, three patients had false-negative results (two had metastatic nodes in the contralateral pelvic area and one in the para-aortic area), giving an NPV of 97% (95% CI 91-99) and sensitivity of 84% (62-95). All three of these patients had type 2 endometrial cancer. Immunohistochemistry and serial sectioning detected metastases undiagnosed by conventional histology in nine of 111 (8%) patients with detected SLNs, representing nine of the 19 patients (47%) with metastases. SLN biopsy upstaged 10% of patients with low-risk and 15% of those with intermediate-risk endometrial cancer. INTERPRETATION SLN biopsy with cervical dual labelling could be a trade-off between systematic lymphadenectomy and no dissection at all in patients with endometrial cancer of low or intermediate risk. Moreover, our study suggests that SLN biopsy could provide important data to tailor adjuvant therapy.

Abstract
Lymph node metastases in cervical and endometrial cancer are major prognostic factors. Lymph-nodal involvement determines adjuvant therapy. As imagery is not reliable to diagnose lymph node status, pelvic +/- para-aortic lymphadenectomy remains the gold standard. These surgical procedures are, however, responsible for specific morbidity: lymphocele and lymphedema. Sentinel lymph node procedure could avoid lymphadenectomy and their complications in cervical and endometrial cancer with good negative predictive values. We present actual indications, procedure and results of sentinel lymph node procedures in cervical and endometrial cancer.

Abstract
OBJECTIVE The objective of this study was to compare the initial failure sites in patients with endometrial cancer who underwent surgical treatment including pelvic lymphadenectomy with or without para-aortic lymphadenectomy. METHODS A retrospective chart review was carried out for 657 endometrial cancer patients with no residual disease after initial treatments including lymphadenectomy at two tertiary centers between 1987 and 2004. Surgical treatment at one institute included pelvic lymphadenectomy (PLX) without para-aortic lymphadenectomy (PALX), while surgical treatment including PLX+PALX was routinely performed at the other institute. We identified patients with recurrence and evaluated initial failure sites. Rates of recurrence in the respective sites were compared according to the type of lymphadenectomy. RESULTS Of the 657 patients, 103 (15.7%) suffered recurrence. There was no significant difference between the rate of intrapelvic recurrence in the PLX alone group and that in the PLX+PALX group (4.7% vs. 2.9%, p=0.22). The rate of extrapelvic recurrence in the PLX alone group was significantly higher than that in the PLX+PALX group (16.1% vs. 6.2%, p<0.0001), and the rate of para-aortic node (PAN) recurrence in the PLX alone group was also significantly higher than that in the PLX+PALX group (5.1% vs. 0.6%, p=0.0004). In the analysis of patients who received adjuvant chemotherapy, the rate of PAN recurrence in the PLX alone group was significantly higher than that in the PLX+PALX group (9.5% vs. 1.3%, p=0.0036). CONCLUSION PAN recurrence was a failure pattern peculiar to the PLX alone group. Adjuvant chemotherapy might not be able to replace surgical removal as a treatment for metastatic lymph nodes.

Abstract
Introduction:Although para-aortic lymphadenectomy (PALX) has not been accepted as a standard treatment for patients with endometrial cancer, it is possible that systematic lymphadenectomy including PALX has therapeutic significance for patients with intermediate-/high-risk endometrial cancer. On the other hand, a consensus regarding the safety of PALX has not been reached. The aim of this study was to compare the incidence rates of postoperative complications after pelvic lymphadenectomy (PLX) with or without PALX in patients with uterine corpus cancer.Methods:A retrospective chart review was carried out for all patients with endometrial cancer treated at 2 tertiary centers between 1998 and 2004. Surgery at one institute included both PLX and PALX, whereas PLX alone was routinely performed at the other institute. A total of 142 patients underwent PLX + PALX and 138 patients underwent PLX alone. We evaluated postoperative complications including intraoperative injury, ileus, lymphedema, lymphocyst, and thrombosis.Results:There was no fatal accident associated with surgery. Lymphedema was the most frequent complication. Comparing the PLX + PALX group and the PLX group, there were no significant differences in the rate of cases of lymphedema (23.2% vs 28.3%), lymphocyst (9.2% vs 9.4%), and thrombosis (4.9% vs 2.2%). The rate of cases of mild/moderate ileus in the PLX + PALX group was significantly higher than that in the PLX group (10.5% vs 2.9%; P = 0.011). However, no significant difference in the rates of cases of severe ileus was found between the 2 groups (1.4% vs 0.7%). There were also no significant differences between the 2 groups in the rates of intraoperative organ injury (2.8% vs 2.2%) and secondary operation for postoperative complications (4.9% vs 4.3%).Conclusions:Para-aortic lymphadenectomy can be performed with an acceptable morbidity under the conditions in which it is performed by experienced surgeons, and measures to prevent complications are properly taken.

Abstract
Endometrial cancer is the most frequent malignant tumor of the female genital tract. Traditionally, surgical treatment is performed via laparotomy, but laparoscopy has recently gained wider acceptance. Data regarding survival and recurrence are comparable in case of laparotomy or laparoscopy. Surgical morbidity and postoperative recovery time are significantly lower by laparoscopy. In case of early endometrial cancer laparoscopy is an invaluable alternative method of choice but it has to be performed by skilled laparoscopic surgeons. Authors review the current literature regarding the role of laparoscopy in the treatment of early stage endometrial cancer.

Abstract
BACKGROUND AND OBJECTIVES Recent studies reported the feasibility of intraoperative lymphatic mapping in women with endometrial cancer but none of these studies compared the sentinel lymph nodes (SLNs) detection rates obtainable through laparoscopy or laparotomy. The purpose of this study was to address this issue. METHODS Thirty-four patients with clinical stage I-II endometrial cancer were enrolled in this prospective comparative trial. Four milliliters of Patent Blue Violet were injected into the cervix after the induction of general anesthesia. The assessment of SLNs was done in 17 patients through laparoscopy and in 17 patients through laparotomy as first step of systematic pelvic lymphadenectomy. Both SLNs and non-SLNs were evaluated for micrometastases. RESULTS The SLNs detection rate was significantly higher (82%) for laparoscopy than for laparotomy (41%; P = 0.008). Pelvic lymph node metastases were present in 6 out of 34 patients (18%) but only 3 (50%) of these patients were correctly identified. CONCLUSIONS SLNs detection rate is significantly higher through laparoscopy than through laparotomy after vital dye pericervical injection but intraoperative vital dye pericervical injection is not reliable as part of standard care for predicting lymphatic spread in women with early stage endometrial cancer.

Abstract
Background Lymph node status is an important prognostic factor and a criterion for adjuvant therapy in uterine cancers. While detection of micrometastases by ultrastaging techniques is correlated to prognosis in several other cancers, this remains a matter of debate for uterine cancers. The objective of this review on sentinel nodes (SN) in uterine cancers was to determine the contribution of ultrastaging to detect micrometastases. Methods Review of the English literature on SN procedure in cervical and endometrial cancers and histological techniques including hematoxylin and eosin (H&E) staining, serial sectioning, immunohistochemistry (IHC) and molecular techniques to detect micrometastases. Results In both cervical and endometrial cancers, H&E and IHC appeared insufficient to detect micrometastases. In cervical cancer, using H&E, serial sectioning and IHC, the rate of macrometastases varied between 7.1% and 36.3% with a mean value of 25.8%. The percentage of women with micrometastases ranged from 0% and 47.4% with a mean value of 28.3%. In endometrial cancer, the rate of macrometastases varied from 0% to 22%. Using H&E, serial sectioning and IHC, the rate of micrometastases varied from 0% to 15% with a mean value of 5.8%. In both cervical and endometrial cancers, data on the contribution of molecular techniques to detect micrometastases are insufficient to clarify their role in SN ultrastaging. Conclusion In uterine cancers, H&E, serial sectioning and IHC appears the best histological combined technique to detect micrometastases. Although accumulating data have proved the relation between the risk of recurrence and the presence of micrometastases, their clinical implications on indications for adjuvant therapy has to be clarified.

Abstract
OBJECTIVE The aim of this study was to identify the immune response in sentinel lymph nodes (SLNs) of patients with endometrial and patients with cervical cancers by analyzing the number of S-100-, CD1a-, CD83-positive (+) dendritic cells that are the major antigen-presenting cells. METHODS A total of 56 patients with early-stage cancer (n = 32, with cervical; n = 24, with endometrial cancer) underwent SLN biopsy. Sentinel lymph nodes and non-SLNs were stained with antibodies against S-100, CD1a, and CD83 as markers for dendritic cells to find out whether SLNs were immunomodulated compared with non-SLNs. RESULTS The mean values of S-100(+) and CD1a(+) dendritic cells in both the tumor-free and the metastatic SLNs were significantly higher than those of both the tumor-free and the metastatic non-SLNs. When metastatic SLNs were compared with nonmetastatic SLNs, CD83(+) dendritic cells were found significantly more abundant in nonmetastatic SLNs. CONCLUSIONS Significantly higher numbers of S-100(+) and CD1a(+) dendritic cells in the SLNs compared with those in the non-SLNs may indicate that SLNs are the first sites of immunostimulation. Immunosupression may be the underlying factor for the metastatic involvement of SLNs, which might be secondary to the significantly decreased number of mature dendritic cells in metastatic SLNs compared with tumor-free SLNs.

Abstract
OBJECTIVE To describe the accuracy of SLN mapping in patients with a preoperative diagnosis of grade 1 endometrial cancer. METHODS A prospective, non-randomized study of women with a preoperative diagnosis of endometrial cancer and clinical stage I disease was conducted. A subset analysis of patients with a preoperative diagnosis of grade 1 endometrial endometrioid cancer was performed. All patients had preoperative lymphoscintigraphy with Tc99m on the day of or day before surgery followed by an intraoperative injection of 2 cm(3) of isosulfan or methylene blue dye deep into the cervix or both cervix and fundus. All patients underwent hysterectomy, bilateral salpingo-oophorectomy, and regional nodal dissection. Hot and/or blue nodes were labeled as SLNs and sent for histopathological analysis. RESULTS Forty-two patients with a preoperative diagnosis of grade 1 endometrial carcinoma treated from 3/06 to 8/08 were identified. Twenty-five (60%) had laparoscopic surgery; 17 (40%) were treated by laparotomy. Preoperative lymphoscintigraphy visualized SLNs in 30 patients (71%); intraoperative localization of the SLN was possible in 36 patients (86%). A median of 3 SLNs (range, 1-14) and 14.5 non-SLNs (range, 4-55) were examined. In all, 4/36 (11%) had positive SLNs-3 seen on H&E and 1 as cytokeratin-positive cells on IHC. All node-positive cases were picked up by the SLN; there were no false-negative cases. The sensitivity of the SLN procedure in the 36 patients who had an SLN identified was 100%. CONCLUSION Sentinel lymph node mapping using a cervical injection with combined Tc and blue dye is feasible and accurate in patients with grade 1 endometrial cancer and may be a reasonable option for this select group of patients. Regional lymphadenectomy remains the gold standard in many practices, particularly for the approximately 15% of cases with failed SLN mapping.

Abstract
The concept of radioguided surgery, which was first developed some 60 years ago, involves the use of a radiation detection probe system for the intraoperative detection of radionuclides. The use of gamma detection probe technology in radioguided surgery has tremendously expanded and has evolved into what is now considered an established discipline within the practice of surgery, revolutionizing the surgical management of many malignancies, including breast cancer, melanoma, and colorectal cancer, as well as the surgical management of parathyroid disease. The impact of radioguided surgery on the surgical management of cancer patients includes providing vital and real-time information to the surgeon regarding the location and extent of disease, as well as regarding the assessment of surgical resection margins. Additionally, it has allowed the surgeon to minimize the surgical invasiveness of many diagnostic and therapeutic procedures, while still maintaining maximum benefit to the cancer patient. In the current review, we have attempted to comprehensively evaluate the history, technical aspects, and clinical applications of radioguided surgery using gamma detection probe technology.

Abstract
OBJECTIVE Lymph node status in endometrial cancer is a major prognostic factor. Sentinel lymph node (SLN) biopsy using radiocolloid and blue dye labeling has emerged as an alternative to systematic lymphadenectomy. This technique requires a preoperative lymphoscintigraphy. The aim of this study was to evaluate the limits of day-before preoperative lymphoscintigraphy to SLN biopsy. METHODS Between July 2002 and March 2007, 38 patients with endometrial cancer underwent laparoscopic SLN procedure using radiocolloid and blue dye. Those with early-stage I endometrial cancer (35 patients) underwent a SLN procedure followed by systematic pelvic lymphadenectomy and a hysterectomy with bilateral salpingo-oophorectomy while those with presumed stage IIB on MR imaging (3 patients) underwent a radical hysterectomy. Omentectomy and paraaortic lymphadenectomy were also performed for women with clear cell or serous papillary carcinoma (5 patients). The SLN identification rates and false-negative rates were studied. RESULTS The detection rate of lymphoscintigraphy was 84.5% (32/38), with 1.9 nodes per patient. Eight of 17 patients (47%) with unilateral sentinel lymph node on lymphoscintigraphy had bilateral SLNs at surgery and three of 15 patients (20%) with bilateral SLN on lymphoscintigraphy had unilateral SLN at surgery. The correlation was poor (kappa=0.266). When categorized in <2 and > or =2 sentinel nodes, the correlation between lymphoscintigraphic and surgical SLN mapping was moderate (kappa=0.33). CONCLUSION Our results demonstrated the low correlation between day-before lymphoscintigraphy and surgical SLN mapping raising issues of its usefulness and cost-effectiveness in routine practice.

Abstract
The objective of this study was to review available literature pertaining to lymphatic mapping in endometrial cancer. We reviewed all published series of lymphatic mapping in endometrial cancer available through a PubMed search. Techniques used for identification of sentinel lymph nodes fell into three main categories in relation to the site of injection: 1) uterine subserosal, 2) cervical, and 3) endometrial via hysteroscopy. High detection rates may be achieved in all three categories. The use of both radiolabeled technetium and blue dye has been reported. A combination of cervical and uterine corpus injections appears feasible and less technically demanding than hysteroscopic injections. Immunohistochemistry staining of sentinel nodes coupled with step-serial section may improve the detection of micrometastasis in sentinel nodes. Meaningful sensitivity and false-negative rates cannot be calculated from current series due to their small numbers. The role of lymphatic mapping in endometrial carcinoma and the optimal injection site remains to be determined. A combination of cervical and uterine fundal injections may result in acceptable detection rates. Large-scale validation trials requiring complete pelvic and para-aortic lymphadenectomy are needed to evaluate its role in future clinical practice.

Abstract
BACKGROUND The lymph node status of a patient is a key determinate in staging, prognosis and adjuvant treatment of endometrial cancer. Despite this, the potential additional morbidity associated with lymphadenectomy makes its role controversial. This study systematically reviews the accuracy literature on sentinel node biopsy; ultra sound scanning, magnetic resonance imaging (MRI) and computer tomography (CT) for determining lymph node status in endometrial cancer. METHODS Relevant articles were identified form MEDLINE (1966-2006), EMBASE (1980-2006), MEDION, the Cochrane library, hand searching of reference lists from primary articles and reviews, conference abstracts and contact with experts in the field. The review included 18 relevant primary studies (693 women). Data was extracted for study characteristics and quality. Bivariate random-effect model meta-analysis was used to estimate diagnostic accuracy of the various index tests. RESULTS MRI (pooled positive LR 26.7, 95% CI 10.6 - 67.6 and negative LR 0.29 95% CI 0.17 - 0.49) and successful sentinel node biopsy (pooled positive LR 18.9 95% CI 6.7 - 53.2 and negative LR 0.22, 95% CI 0.1 - 0.48) were the most accurate tests. CT was not as accurate a test (pooled positive LR 3.8, 95% CI 2.0 - 7.3 and negative LR of 0.62, 95% CI 0.45 - 0.86. There was only one study that reported the use of ultrasound scanning. CONCLUSION MRI and sentinel node biopsy have shown similar diagnostic accuracy in confirming lymph node status among women with primary endometrial cancer than CT scanning, although the comparisons made are indirect and hence subject to bias. MRI should be used in preference, in light of the ASTEC trial, because of its non invasive nature.

Hysteroscopy in endometrial cancer: new methods to evaluate transtubal leakage of saline distension medium. Am J Obstet Gynecol 2008; 198:214.e1-4. [PMID: 18226628 DOI: 10.1016/j.ajog.2007.07.035] [Citation(s) in RCA: 15] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/23/2007] [Revised: 05/05/2007] [Accepted: 07/23/2007] [Indexed: 10/22/2022]
Abstract
OBJECTIVE This study was undertaken to evaluate transtubal fluid leakage after low pressure office saline solution hysteroscopy. STUDY DESIGN Forty stage I/II endometrial cancer patients were submitted to office hysteroscopy at the National Cancer Institute of Milan. Uterine cavity was distended by a 1000-mL saline solution bag, placed 50 cm above the patient's plane. After visualization of uterine cavity, a radiotracer (technetium Tc 99m) and patent blue dye were injected subendometrially. During the staging surgery peritoneal free fluid was analyzed to detect patent blue dye, technetium Tc 99m or free cancer cell by cytologic examination. RESULTS Technetium Tc 99m and patent blue dye were detected on the peritoneal surface and in the peritoneal fluid in 2 patients. In 1 of these peritoneal cytology was negative for cancer cells. Peritoneal cytology was positive in 2 cases. CONCLUSION The risk of transtubal fluid leakage during hysteroscopy is absent when performed with intrauterine pressure less than 40 mm Hg. Transtubal fluid leakage is not a synonym of cancer cell dissemination.

Abstract
BACKGROUND The sentinel node (SN) is defined as the first node in the lymphatic system that drains a tumor site. If the SN is not metastatic, then all other nodes should also be disease-free. We used serial sections and immunohistochemical (IHC) staining to examine both SN and non-sentinel nodes (non-SNs). PATIENTS AND METHODS Twenty-three patients (median age 69 years) with early endometrial cancer underwent a laparoscopic SN procedure based on a combined detection method, followed by complete laparoscopic pelvic lymphadenectomy. If the SN was free of metastasis by both hematoxylin and eosin (H&E) and IHC staining, all non-SNs were also examined by the combined staining method. RESULTS SNs were identified in 19 patients (82.6%). A total of 47 SNs were removed (mean 2.5). Ten SNs (21.3%) from five patients (26.3%) were found to be metastatic at the final histologic assessment. In 14 patients, no metastatic SN involvement was detected by H&E and IHC staining. In these 14 patients, 120 non-SNs were examined by serial sectioning and IHC, and none were found to be metastatic. CONCLUSION The SN procedure appears to reliably predict the metastatic status of the regional lymphatic basin in patients with early endometrial cancer.

Abstract
In cancer research, regional lymph node status is a major prognostic factor and a decision criterion for adjuvant therapy. The sentinel node procedure, which has emerged to reduce morbidity of extensive lymphadenectomy, remains a major step in the surgical management of various cancers. Sentinel node procedure has become a standard technique for the determination of the nodal stage of the disease in patients with melanoma, vulvar cancer and in breast cancer. In endometrial cancer, the sentinel node biopsy is still at the stage of feasibility. In this article, we review the technical aspects, results, clinical implications and limitations of sentinel node procedure in endometrial cancers.

Abstract
PURPOSE The objective of the study was to determine the feasibility of a new method of labeling sentinel lymph nodes in patients with endometrial cancer using blue dye. PATIENTS AND METHODS 4 ml of blue dye was subserously administered in 25 patients with endometrial cancer at eight sites. After 8 min, sentinel lymph nodes were harvested. RESULTS Detection rate was 92.0%, sensitivity was 62.5%, and negative predictive value was 92.5%. In two patients there was no detection of sentinel nodes and in addition in two patients only sentinel nodes were harvested due to minimal disease. No side effects occurred. CONCLUSIONS This new and simple approach yielded a high pelvic detection rate. This new approach reveals a way to label sentinel nodes in endometrial cancer. Combining a different labeling agent with the proposed new method might overcome the lack of para-aortic sentinel detection.
