Abstract
BACKGROUND Lymphatic involvement is the most important prognostic factor in early-stage cervical cancer. Sentinel lymph node biopsy is a viable alternative to systematic lymphadenectomy and may identify metastases more precisely. OBJECTIVE To compare two tracers (indocyanine green and patent blue) to detect sentinel nodes. METHODS A single-center, retrospective study of women treated due to early-stage cervical cancer (International Federation of Gynecology and Obstetrics 2009 IA1 with lymphovascular invasion, IA2, and IB1). Location and tracer of all detected sentinel nodes had been documented for a prospective, multicenter trial (SENTIX trial). All sentinel nodes were sent to frozen section and final analysis through ultrastaging using a standard protocol. RESULTS Overall, 103 patients were included. Bilateral detection rate for indocyanine green (93.2%) was significantly higher than for blue dye (77.7%; p=0.004). Their combined use significantly increased the bilateral detection to 99.0% (p=0.031). While 97.4% of all sentinel nodes were located below the common iliac vessels, no para-aortic nodes were labeled. Simultaneous bilateral detection with both tracers was found in 71.8% of the cases, of which the sentinel nodes were identical in 91.9%. Nine positive nodes were detected among seven patients (6.8%), all marked with indocyanine green while patent blue labeled six. Frozen section failed to detect one of three macrometastases and three of four micrometastases (sensitivity 43%; negative prediction value 96%). CONCLUSION Anatomical distribution and topographic localization of the sentinel nodes obtained with these tracers were not different. Indocyanine green provided a significantly higher bilateral detection rate and had superior sensitivity to detect positive nodes compared with patent blue. Combining indocyanine green and blue dye increased the bilateral detection rate significantly.

Abstract
OBJECTIVE This study aimed to validate the surgical and oncologic outcomes of robotic surgery with sentinel node navigation surgery (SNNS) in endometrial cancer. METHODS This study included 130 patients with endometrial cancer, who underwent robotic surgery, including hysterectomy, bilateral salpingo-oophorectomy, and pelvic SNNS at the Department of Obstetrics and Gynecology of Kagoshima University Hospital. Pelvic sentinel lymph nodes (SLNs) were identified using the uterine cervix 99m Technetium-labeled phytate and indocyanine green injections. Surgery-related and survival outcomes were also evaluated. RESULTS The median operative and console times and volume of blood loss were 204 (range: 101-555) minutes, 152 (range: 70-453) minutes, and 20 (range: 2-620) mL, respectively. The bilateral and unilateral pelvic SLN detection rates were 90.0% (117/130) and 5.4% (7/130), respectively, and the identification rate (the rate at which at least one SLN could be identified on either side) was 95% (124/130). Lower extremity lymphedema occurred in only 1 patient (0.8%), and no pelvic lymphocele occurred. Recurrence occurred in 3 patients (2.3%), and the recurrence site was the abdominal cavity, with dissemination in 2 patients and vaginal stump in one. The 3-year recurrence-free survival and 3-year overall survival rates were 97.1% and 98.9%, respectively. CONCLUSION Robotic surgery with SNNS for endometrial cancer showed a high SLN identification rate, low occurrence rates of lower extremity lymphedema and pelvic lymphocele, and excellent oncologic outcomes.

Abstract
Cervical cancer (CC) is a frequent disease in women whose development is related with miRNA disorder. MiR-377-5p plays a negative role in the development of some tumors, while few studies have revealed its role in CC. In this study, the functions of miR-377-5p in CC were investigated by bioinformatics. Briefly, the expression and survival curve of miR-377-5p in CC was analyzed with the Cancer Genome Atlas (TCGA) database, and the abundance of miR-377-5p in clinical samples and CC cell lines were measured by qRT-PCR. Moreover, the MicroRNA Data Integration Portal (miRDIP) database was used to predict targets of miR-377-5p, and the Database for Annotation Visualization and Integrated Discovery (David) was used for enrichment analysis of the functions of the miR-377-5p. The Search Tool for the Retrieval of Interacting Genes (STRING) database was used to screen the hub targets of miR-377-5p. Moreover, the Gene Expression Profiling Interactive Analysis (GEPIA) database was used to analyze the abundance of the genes in CC. Results showed that decreased miR-377-5p was found in the CC tissues and cell lines, and low miR-377-5p was connected with poor prognosis of patients. Besides, the targets of miR-377-5p were enriched in the PI3K/AKT, MAPK and RAS signaling pathways. Moreover, CDC42, FLT1, TPM3 and CAV1 were screened as hub nodes in the targets of miR-377-5p, and increased CDC42, FLT1, TPM3 and CAV1 also indicated the poor survival rates of the patients in the long term. In conclusion, this study suggests that miR-377-5p downregulation is a biomarker event for CC progression.

Abstract
PURPOSE OF REVIEW This article discusses recent developments towards less radical surgical treatment for early-stage cervical cancer. RECENT FINDINGS Surgery is the standard treatment for early-stage cervical cancer. In the last decades, new treatment strategies have been developed aiming to reduce morbidity, without hampering oncological safety. We provide an update of the latest knowledge on safety and morbidity following less radical surgical procedures in early-stage cervical cancer. In cervical cancer with a tumour size of 2 cm or less, radical surgery (simple hysterectomy or fertility-sparing conisation) may be a well tolerated option. For patients with larger lesions (>2 cm) and wishing to preserve fertility, administration of neoadjuvant chemotherapy followed by less extensive surgery appears to be a feasible and well tolerated alternative to abdominal trachelectomy. With regard to lymph node assessment, increasing evidence shows the feasibility of the sentinel lymph node procedure instead of full pelvic lymphadenectomy. Prospective trials reporting on oncological safety are awaited.It is important to exercise caution when new surgical strategies are introduced. Despite promising retrospective data, prospective randomized studies may present unexpected results, for instance, minimally invasive radical hysterectomy showed inferior results compared to laparotomy. SUMMARY There is a shift towards less radical treatment for early-stage cervical cancer. This review explores whether and when less is really more.

Abstract
BACKGROUND Lymph node metastasis is a critical prognostic factor in cervical cancer. Considering the potential complications of lymphadenectomy and desirability of avoiding systemic lymphadenectomy, accurate intraoperative prediction of the existence of lymph node metastasis is important in patients undergoing surgery for cervical cancer. We evaluated the feasibility and value of indocyanine green (ICG) use for sentinel lymph node (SLN) mapping during laparoscopic surgery performed for cervical cancer. METHODS This single-center cohort study included 77 patients undergoing a new laparoscopic radical surgery method with pelvic lymphadenectomy for early-stage cervical cancer. The surgery, performed without using a uterine manipulator, included creation of a vaginal cuff. Bilateral ICG-guided SLN mapping and rapid histopathological examination were performed, and results were analyzed in relation to final histopathologic diagnoses. RESULTS The SLN pelvic side-specific detection rate was 93.5%, sensitivity (SLN-positive cases/SLN-detected pelvic lymph node-positive cases) was 100%, intraoperative negative predictive value (NPV) was 97.8%, and final pathological NPV was 100%. The detection rate was significantly lower for tumors ≥ 2 cm in diameter than for tumors < 2 cm in diameter. Micrometastases were missed by intraoperative examination in 3 cases. CONCLUSION The high NPV suggests the feasibility and usefulness of ICG-based SLN mapping plus rapid intraoperative examination for identification of metastatic SLNs. Use of ICG-based mapping for intraoperative identification of SLNs in patients undergoing this new laparoscopic surgery method for early-stage cervical cancer was particularly effective for tumors < 2 cm in diameter. However, incorporating a search for micrometastases into rapid intraoperative histopathologic examination may be necessary.

Comparison of Prognosis between Minimally Invasive and Abdominal Radical Hysterectomy for Patients with Early-Stage Cervical Cancer. Curr Oncol 2022; 29:2272-2283. [PMID: 35448159 PMCID: PMC9026697 DOI: 10.3390/curroncol29040185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2022] [Revised: 03/02/2022] [Accepted: 03/21/2022] [Indexed: 11/16/2022] Open
Abstract
Minimally invasive surgery (MIS) is performed to treat cervical cancer patients; however, a recent study showed that MIS was associated with higher recurrence and death rate compared with abdominal radical hysterectomy (ARH). In the current study, the prognosis of patients with early-stage cervical cancer who underwent MIS with vaginal closure or ARH was evaluated. One hundred and eighty-two patients underwent radical hysterectomy for cervical cancer with stage of IA2, IB1, and IIA1. MIS was performed by laparoscopy or a robot using the vaginal closure method. Disease-free survival (DFS) and overall survival (OS) were evaluated between the groups. Among the patients, 67 underwent MIS and 115 underwent ARH. The recurrence rate was 4.5% in MIS patients and 3.5% in ARH patients with a median follow-up (interquartile range) of 36 (18–60) and 78 (48–102) months, respectively. DFS and OS were not different between the groups (3y-DFS, 95.3% vs. 96.1%, p = 0.6; 3y-OS, 100% vs. 100%, p = 0.06). In early-stage cervical cancer patients, MIS with vaginal closure did not increase the risk for recurrence or death. Surgical techniques and procedures to avoid spillage of tumor cells could be important for a better prognosis.

Abstract
This study aimed to assess the accuracy of predicting pelvic lymph node status using sentinel lymph node (SLN) biopsy with indocyanine green (ICG) and to examine the outcomes of SLN biopsy-guided abdominal radical trachelectomy (ART). Patients with stage IA2-IB2 cervical cancer from January 2009 to January 2021 were included. ICG was injected before ART and SLNs were identified, excised, and assessed intraoperatively using fast-frozen sections. Systemic pelvic lymphadenectomy was subsequently performed. The SLN detection rate, sensitivity, and false-negative rate were determined. Thirty patients desiring fertility preservation were enrolled, of whom 26 successfully completed ART and four underwent radical hysterectomies because of metastatic primary SLNs. Bilateral SLNs were identified in all patients. The sensitivity, false-negative rate, and negative predictive value were 100%, 7.7%, and 92.3%, respectively. Three (12%) patients were lost to follow-up: two relapsed and one died of tumor progression. Of the nine patients who tried to conceive after surgery, four achieved pregnancy and three delivered healthy live infants. In women with early-stage cervical cancer who desired to conserve fertility, SLN mapping with ICG had a very high detection rate, sensitivity, and low false-negative rate. SLN biopsy-guided ART is a feasible and accurate method for assessing pelvic node status.

Abstract
BACKGROUND The value of sentinel lymph node (SLN) mapping for early-stage cervical cancer remains controversial. Therefore, we collected data to investigate the feasibility and diagnostic accuracy of SLN in patients with early-stage (IA-IIA) cervical cancer. METHODS We searched Embase, PubMed, and the Cochrane Library databases issued before June 1, 2020. The sample size of the selected study was at least 10 patients with early-stage (IA-IIA) cervical cancer, the pooled detection rates and the separate detection rate (overall detection rate, bilateral detection rate) using blue dye with Tc, technetium 99 (Tc) and indocyanine green (ICG) technique of early-stage cervical cancer was reported. R-3.6.1 software was used to evaluate pooled detection rate and sensitivity. RESULTS Two thousand one hundred sixty-four patients included for analysis in 28 studies ranging from 12 to 405 patients. The combined overall detection rate of SLN mapping was 95% with a 72% pooled bilateral detection rate. The sensitivity of the combined overall detection rate of SLN mapping was 94.99% as well as a sensitivity of 72.43% bilateral detection rate. The overall detection rate of SLN was 96% for blue dye with Tc, 95% for Tc, 98% for ICG technique. The bilateral detection rate of SLN was 76% for blue dye with Tc, 63% for Tc, 85% for ICG technique. The sensitivity of the overall detection rate of SLN mapping was 97.76% as well as a sensitivity of 84.96% bilateral detection rate of ICG technique. CONCLUSION In early-stage cervical cancer, overall detection rate of SLN mapping is elevated while bilateral detection rate is lower. The overall detection rate (98%) as well as bilateral rate (85%) of ICG seems to be a better SLN mapping technique among the method of SLN mapping (using blue dye with Tc, Tc or ICG). We believe SLN mapping may be considered contemporary technique which could provide additional benefits over traditional pelvic lymphadenectomy. While promising results in SLN mapping has been found, larger patient samples, including randomized studies, are required at the same time.

Abstract
BACKGROUND Sentinel lymph node (SN) biopsy is essential for evaluating survival and minimal treatment-related morbidity associated with cervical, endometrial, and vulvar cancer in Japan. As such, our aim in this study was to evaluate the current practice pattern of using SN biopsy for cervical, endometrial, and vulvar cancer in Japan. METHODS We deployed a 47-question survey on the use of SN biopsy for gynecological cancers to 216 gynecological oncology training facilities. The survey included information on the use of SN biopsy for uterine (cervical and endometrial) and vulvar cancers; details on the type, timing, and concentration of tracers used; surgical approach used for SN biopsy; method of biopsy and pathological examination; and facilities' experience with clinical research on SN biopsy. RESULTS The response rate was 84% (181/216), with 40 facilities (22%) having experience in SN biopsy for gynecological cancers, 34 (85%) for uterine cancers, and 15 (37%) for vulvar cancers. Radioisotope, indocyanine green (ICG), and blue dyes were available for the detection of uterine cancers in 21 (52%), 25 (62%), and 19 (48%) facilities and for vulvar cancers in 9 (22%), 3 (7%), and 11 (27%) facilities, respectively. Thirty-four facilities (85%) used intraoperative frozen section procedure for diagnosis when possible, with 24 (71%) of these facilities using 2-mm specimen cuts. Diagnosis included pathological examination (85%), immunostaining (57%), and one-step nucleic acid amplification (5%). CONCLUSION Increasing research evidence, providing insurance coverage for radioisotope tracers, and increasing the availability of training are expected to increase the use of SN biopsy in Japan.

Abstract
Background The aim of this study was to determine the specific side detection rate of the sentinel lymph node biopsy and the accuracy in predicting lymph node metastasis in early stage cervical cancer. Methods A systematic search of databases was performed from the inception of the databases to 27 June 2020. Studies of cervical cancer patients with FIGO stage FIGO ⅠA~ⅡB, evaluating the sentinel lymph node biopsy with blue dye, technetium 99, combined technique (blue dye with technetium 99) or indocyanine green with a reference standard of systematic pelvis lymph node dissection or clinical follow‐up were included. Stata12.0 and Meta‐Disc 1.4 were used for the meta‐analysis. Results Of 2825 articles found, 21 studies (2234 women) were eventually included. Out of 21 studies, 20 met the detection rate evaluation criteria and six were included for sensitivity meta‐analysis. Due to heterogeneity, it was inappropriate to pool all studies. The pooled specific side detection rates were 85% in tumors up to 2 cm, 67% in tumors over 2 cm, 75.2% for blue dye, 74.7% for technetium 99, 84% for combined technique, and 85.5% for indocyanine green. The sentinel lymph node biopsy had a pooled specific side sensitivity of 88%. Adverse effects of sentinel lymph node biopsy appear minimal for most patients and are mainly related to the injection of blue dye. Conclusions Sentinel lymph node biopsy using a tracer with a high detection rate and ultrastaging is highly accurate and reliable when limited to seriously selected patients, with satisfactory bilateral lymph node mapping and where enough cases for learning curve optimization exist. Indocyanine green sentinel lymph node mapping seems to be a superior sentinel lymph node mapping technique compared to other methods at present.

Abstract
PURPOSE We aimed to assess the impact of low-volume metastasis (micrometastasis and isolated tumor cells) on disease-free survival (DFS) of women with early-stage cervical cancer. METHODS Women with clinically suspected stage 1A-IB2 (FIGO 2018 classification) disease who underwent retroperitoneal nodal staging between October 2010 and April 2018, were retrospectively analyzed. The group of women who had undergone lymphadenectomy and standard node pathologic analysis (H&E group), were compared to the group undergoing sentinel node mapping (SLN) and ultrastaging with or without lymphadenectomy (ultrastaging group). At a median follow-up of 45 months, the DFS curves were analyzed. RESULTS Overall, 573 patients were revised (272 in the H&E group and 302 in the ultrastaging group). Eighty-five patients presented lymph node metastasis (32 in H&E, 53 in ultrastaging). Ultrastaging protocol increased the rate of low-volume metastasis by 5.6%. Twenty patients showed exclusive micrometastasis or ITC's. Seventy-three recurrences occurred (35 in H&E, 38 in ultrastaging). Only 1 out of 53 patients in the ultrastaging group (1.9%) presented with micrometastasis recurred. The 3-year disease-free survival was 89% for the H&E group, and 88% for the ultrastaging group, respectively (p = 0.175). CONCLUSION Ultrastaging analysis allowed increasing the detection of low volume metastasis in women with early-stage cervical cancer. However, the type of nodal staging did not have an impact on patients' 3-year disease-free survival.

Abstract
OBJECTIVE To evaluate the diagnostic accuracy of sentinel lymph node (SLN) biopsy and to determine clinical significance of preoperative single-photon emission computed tomography/computed tomography (SPECT-CT). METHODS We retrospectively evaluate data and images of 55 women with stage IAB-IIA cervical cancer that underwent sentinel lymph node biopsy and subsequent lymph node dissection. 99mTc-phytate (300 MBq) was injected submucosally in 4 points and SPECT-CT started 2 h after the injection. All lymph nodes (LN) that accumulated radiocolloids were regarded as sentinel. Next day after the mapping radical hysterectomy with complete pelvic and parametrial LN dissection and SLN biopsy were performed according to the institute protocol. RESULTS SPECT-CT identified SLNs in 51 of 55 patients. All SLNs were successfully detected during the surgery. The SLN mapping efficacy was 92.7%. LN metastases were diagnosed in 6/51 (11.8%) cases, including 2 patients with positive SLNs. Sensitivity, negative predictive value (NPV) and false-negative rate for SLN biopsy were as follows: 33.4%, 91.8% and 66.6%. In patients with unilateral SPECT-CT localization of SLNs, LN metastases were identified in 4 (20%) of 20 patients but SLN biopsy was false negative in all cases. In 31 women, SPECT-CT detected SLNs on both sides of the pelvis. In this group, regional LN metastases were diagnosed in 2 patients, and in both cases metastases were detected only in SLNs. CONCLUSIONS In women with SPECT-CT visualization of SLNs on both sides of the pelvis, SLN biopsy had high sensitivity and NPV. In patients with unilateral SLN localization, SLN biopsy cannot be used for the prediction of regional LN status.

Abstract
OBJECTIVES To determine the diagnostic performance and optimal protocol of frozen section examination (FSE) in SLNB for cervical cancer. METHODS PubMed, EMBASE, Web of Science, Cochrane Library, Wanfang Data and China National Knowledge Infrastructure were searched from inception to July 30, 2019, for studies concerning SLNB with FSE in cervical cancer. Sensitivity of FSE in detecting SLN metastasis was the primary diagnostic indicator for evaluation. RESULTS The pooled sensitivity of FSE among 31 eligible studies (1887 patients) was 0.77 (95% CI 0.66-0.85) with high heterogeneity (I2 = 69.73%). Two representative sectioning protocols for FSE were identified from 26 studies, described as equatorial (E-protocol, SLN was bisected) and latitudinal (L-protocol, SLN was cut at intervals). Meta-regression showed that FSE protocol was the only source of heterogeneity (p < 0.001). The pooled sensitivity was 0.86 (95% CI 0.79-0.91, I2 = 0%) and 0.59 (0.46-0.72, I2 = 58.47%) for FSE using L- (13 studies, 650 patients) and E- (13 studies, 1047 patients) protocol, respectively. Among the available data, marcometastases (>2 mm) were missed in 4 and 20 patients; small-volume metastases (≤2 mm) were detected in 13 and 2 patients, respectively, under L- and E-protocol. The pooled sensitivity of FSE using L-protocol would reach 0.97 (95% CI 0.89-0.99) if only marcometastases were considered. These findings were robust to sensitivity analyses. CONCLUSION The sectioning protocol determines the accuracy of FSE in SLNB. With L-protocol, FSE can provide precise intraoperative pathology for SLNB, which enables immediate decision-making for individualized managements.

Abstract
Sentinel node biopsy (SNB) may be a decision-making tool for function preservation surgery, including radical trachelectomy and ovary preservation in the treatment of cervical and endometrial cancer. The intraoperative diagnosis is important for guiding treatment decisions for patients with these conditions. Three hundred seventy-one patients with cervical and endometrial cancer received SNB with an intraoperative frozen section analysis and imprint cytology. The sentinel node was cut in half, parallel to the longest axis, to obtain the maximum section area. After performing imprint cytology, one half was used to create a frozen section. The specimen was cut at 2-mm intervals into 5-μm-thick sections, which were subjected to hematoxylin and eosin staining. The diagnostic accuracy of intraoperative frozen section analyses and imprint cytology was compared to the final pathological diagnosis. Among 951 detected sentinel nodes, 51 nodes were found to be positive in the final pathological diagnosis. The sensitivity of a frozen section analysis, imprint cytology and the combination of the two modalities was 76.5%, 72.6%, and 92.2%, respectively. The specificity of a frozen section analysis and imprint cytology was 100%. The negative predictive value of a frozen section analysis and imprint cytology was 98.7% and 98.5%, respectively. In these settings, the accuracy of the frozen section analysis and imprint cytology in the evaluation of SNB specimens was considered acceptable; however, the sensitivity of the combined approach was higher in comparison to when a frozen section analysis or imprint cytology was performed alone.

Comparison of lymphoscintigraphy and single photon emission computed tomography with computed tomography (SPECT/CT) for sentinel lymph node detection in endometrial cancer. Int J Gynecol Cancer 2020; 30:626-630. [PMID: 32200352 DOI: 10.1136/ijgc-2019-001154] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2019] [Revised: 01/30/2020] [Accepted: 02/04/2020] [Indexed: 11/04/2022] Open
Abstract
BACKGROUND Endometrial cancer is the most common gynecologic cancer, and lymph node metastasis is one of the most important prognostic factors. Increasing evidence shows that sentinel lymph node (SLN) mapping is an effective alternative to comprehensive lymphadenectomy. Single photon emission CT with computed tomography (SPECT/CT) is associated with a high SLN detection rate. OBJECTIVE To compare the clinical efficacy of SPECT/CT with that of lymphoscintigraphy in detecting SLNs in patients with endometrial cancer. METHODS Between May 2014 and October 2018, 151 patients with endometrial cancer were enrolled in this study at the Department of Obstetrics and Gynecology of the Kagoshima University Hospital. Inclusion criteria were patients with endometrial cancer, older than 18 years, and with pre-operative International Federation of Gynecology and Obstetrics (FIGO) staging of I and II. All patients underwent pre-operative CT, and patients with suspected peritoneal dissemination and lymph node metastasis were excluded from this study. Pelvic SLNs were detected by injection of tecnetium-99m-labeled phytate into the uterine cervix. The number and locations of SLNs detected using lymphoscintigraphy and SPECT/CT were evaluated. JMP software (version 14, SAS Institute Inc., Cary, North Carolina, USA) was used for statistical analysis. RESULTS A total of 151 patients who underwent pre-operative lymphoscintigraphy and SPECT/CT were included in the study. The median age was 57 years (range 24-79), and the median body mass index was 24.3 kg/m2 (range 16-40). The final pathology was as follows: 135 (89%) endometrioid carcinoma, 11 (7%) serous carcinoma, one (1%) clear cell carcinoma, and four (3%) other histotypes. Based on SPECT/CT, 204 pelvic SLNs were detected. The bilateral pelvic SLN detection rate was better for SPECT/CT (43% (65/151)) than for lymphoscintigraphy (32% (48/151)) (p<0.0001). The overall pelvic SLN detection rate (at least one pelvic SLN detected) was also better with SPECT/CT (77% (16/151)) vs lymphoscintigraphy (68% (102/151)) (p<0.0001). The distribution of SLN locations detected using SPECT/CT was as follows: external iliac, 91 (45%); obturator, 61 (30%); common iliac, 28 (14%); internal iliac, 19 (9%); para-aortic, 2 (1%); parametrium, 2 (1%), and presacral, 1 (1%). The SLN detection rate using SPECT/CT was significantly worse in patients of advanced age (p<0.0001). DISCUSSION Overall and bilateral SLN detection rate was better with SPECT/CT than with lymphoscintigraphy in patients with stage I/II endometrial cancer.

Abstract
PURPOSE Lymph node metastasis is a significant predictive factor for disease recurrence and survival in cervical cancer patients and relevant for therapeutic strategies. We evaluated the clinical value of indocyanine green (ICG) by measuring the sensitivity and negative predictive value of sentinel lymph node mapping compared with the gold standard of complete lymphadenectomy in detecting lymph node metastases for cervical cancer. METHODS We utilized the near-infrared imaging agent ICG to detect tumor-infested lymph nodes in the pelvis analogue to a classical sentinel lymph node procedure by analyzing data from 20 patients who had undergone surgery for cervical cancer at our institution. A laparoscopic lymph node mapping procedure by means of ICG, followed by a complete pelvic lymphadenectomy with or without paraaortic lymphadenectomy was done in all patients. RESULTS Histological examination identified seven patients with tumor-positive pelvic nodes, whereas mapping with ICG identified only five of these patients. Detection rate of positive nodes by ICG mapping and false negative rate was 71.4% and 28.6%, respectively; bilateral detection rate was 83.3%. One of the two false negative patients additionally suffered from deep infiltrating endometriosis. CONCLUSIONS Our results indicate that ICG can identify the relevant pelvic nodes independent of tumor size, provided bilateral detection is achieved and additional, related diseases are excluded. TRIAL REGISTRATION This trial is registered within the German Clinical Trial Register (DRKS-ID: DRKS00014692).

Abstract
CONTEXT.— Ultrastaging of sentinel lymph nodes (SLNs) is a crucial aspect in the approach to SLN processing. No consensual protocol for pathologic ultrastaging has been approved by international societies to date. OBJECTIVE.— To provide a review of the ultrastaging protocol and all its aspects related to the processing of SLNs in patients with cervical cancer. DATA SOURCES.— In total, 127 publications reporting data from 9085 cases were identified in the literature. In 24% of studies, the information about SLN processing is entirely missing. No ultrastaging protocol was used in 7% of publications. When described, the differences in all aspects of SLN processing among the studies and institutions are substantial. This includes grossing of the SLN, which is not completely sliced and processed in almost 20% of studies. The reported protocols varied in all aspects of SLN processing, including the thickness of slices (range, 1-5 mm), the number of levels (range, 0-cut out until no tissue left), distance between the levels (range, 40-1000 μm), and number of sections per level (range, 1-5). CONCLUSIONS.— We found substantial differences in protocols used for SLN pathologic ultrastaging, which can impact sensitivity for detection of micrometastases and even small macrometastases. Since the involvement of pelvic lymph nodes is the most important negative prognostic factor, such profound discrepancies influence the referral of patients to adjuvant radiotherapy and could potentially cause treatment failure. It is urgent that international societies agree on a consensual protocol before SLN biopsy without pelvic lymphadenectomy is introduced into routine clinical practice.

Abstract
Purpose To establish the surgical, demographic and histopathological factors associated with inaccurate sentinel lymph nodes (SLNs) identification using indocyanine green (ICG) and near-infrared (NIR) fluorescence imaging in uterine and cervical neoplasms during both open and laparoscopic surgery. Methods We reviewed patients with atypical endometrial hyperplasia (AEH), clinical stage I and II cervical cancer or uterine malignancies who underwent primary surgery with SLN mapping between September 2015 and January 2018. An analysis of patients’ demographics, tumor factors and surgical approach was conducted. Bilateral and overall detection rates were calculated and univariate analysis was performed to estimate factors associated with failed SLN mapping. Results A total of 32 patients with uterine and cervical neoplasms were included in the study. The overall detection rate of the SLN was 84% and bilateral detection rate was 75%. There were no statistically relevant differences in overall and bilateral SLN detection rates by BMI, surgical approach or age. Regarding endometrial cancer, there were no differences in SLN detection rates when comparing tumor grade, histology nor myometrial invasion. For SLN detection failure, only the presence of metastatic lymph nodes and lack of surgical experience significantly increased the disability to detect SLNs (p = 0.03, p = 0.04, respectively). Conclusions SLN mapping technique using NIR fluorescence imaging with ICG appears to be accurate method in most of the patients with cervical or endometrial carcinoma, regardless of demographic characteristics, tumor-related features and surgical approach. Surgeons’ expertise in that field allows obtaining excellent detection rates.

Abstract
According to the sentinel node biopsy (SNB), systematic pelvic lymph node dissection (PLND) may not be needed for patients with early-stage endometrial cancer. On the other hand, imaging technology including fluorodeoxyglucose-positron emission tomography/computed tomography (FDG PET/CT) has been developing worldwide. The aim of this study was to evaluate the combined diagnostic accuracy of FDG PET/CT and SNB in the prediction of pelvic lymph node metastasis in endometrial cancer patients.One hundred twenty-one patients with endometrial cancer underwent FDG PET/CT before hysterectomy and received SNB followed by systematic PLND. Univariate and multivariate analyses were performed to compare the diagnostic accuracy of FDG PET/CT and SNB in the prediction of pelvic node metastasis to the ultimate histologic status.FDG PET/CT had lower sensitivity (36.8% versus 57.9%, P = .1) and a higher specificity (96.4% versus 84.8%, P < .01) than SNB. The kappa statistics of FDG PET/CT and SNB were 0.37 (95% CI, 0.15-0.59) and 0.72 (95% CI, 0.53-0.90), respectively. The sensitivity of SNB was significantly higher than that of FDG PET/CT in all hemi-pelvises (HPs) in which the short axis of the largest metastatic lymph node was <5 mm in diameter (72.7% versus 18.2%, P = .01). In contrast, the sensitivity of FDG PET/CT was higher than that of SNB in all HPs in which the short axis of the largest metastatic lymph node was ≥5 mm in diameter (62.5% versus 37.5%, P = .2); however, the difference was not statistically significant. When the combined diagnosis of FDG PET/CT and SNB was made, the sensitivity and specificity were 84.2% and 82.1%, respectively.SNB was more useful for detecting lymph node metastasis than FDG PET/CT, especially in patients with small metastatic lymph nodes. The combined diagnosis of FDG PET/CT and SNB improves the sensitivity; PET-positive nodes should be dissected regardless of SNB status and HPs in which SNB was not detected should be dissected systematically regardless of FDG PET/CT status.

Abstract
Systematic pelvic lymph node resection may not be needed for patients with cervical cancer, especially in the early stage, if the pre- or intraoperative diagnosis of lymph node status is correct. The aim of this study was to evaluate the diagnostic accuracy of pelvic lymph node metastasis for fluorodeoxyglucose-positron emission tomography/computed tomography (FDG PET/CT) and sentinel node biopsy (SNB) of cervical cancer patients.Forty-eight patients with cervical cancer were imaged with FDG PET/CT before radical hysterectomy and underwent an SNB followed by systematic pelvic lymph node dissection. The diagnostic accuracy for predicting pelvic node metastases for FDG PET/CT and SNB compared with the ultimate histologic status was analyzed.Among 96 hemi-pelvises (HPs) in 48 patients, pelvic lymph node metastases were obtained in 12 HPs. The sensitivity of pelvic node metastases for FDG PET/CT and SNB was 8.3% and 75.0%, respectively. The specificity for FDG PET/CT and SNB was 97.6% and 94.0%, respectively. The negative predictive value for FDG-PET/CT and SNB was 88.2% and 100%, respectively.SNB is more suitable for detecting pelvic node metastases than FDG PET/CT. The omission of systematic pelvic lymphadenectomy should be considered based on the findings of SNB, not FDG PET/CT.

Abstract
Background The examination of a sentinel lymph node (SLN), where lymph node metastasis first occurs, may be advocated as an alternative staging technique. The aim of this study was to evaluate the feasibility and detection rates of an SLN biopsy in patients with endometrial cancer. Study design Two hundred and eleven patients with endometrial cancer underwent an SLN biopsy at hysterectomy using three kinds of tracers including 99m-technetium-labeled tin colloid (99mTc), indigo carmine and indocyanine green. Factors related to the side-specific detection rate, sensitivity and false negative rate were analyzed. Results The detection rates of the SLN biopsy using 99mTc, indigo carmine and indocyanine green were 77.9, 17.0 and 73.4%, respectively. The detection rate was lower in elderly patients (≥60 years) (67.9 vs 89.2%, p < 0.01), patients with >50% myometrial invasion (68.3 vs 85.2%, p < 0.01), patients with high-grade tumors (69.5 vs 84.9%, p < 0.01) and patients who underwent laparotomy (71.2 vs 84.9%, p < 0.01). There were no significant differences in body mass index. The sensitivity was not significantly different in any factor. However, the false negative rate was higher in patients with > 50% myometrial invasion (11.5 vs 1.2%, p < 0.01), high-grade tumors (13.3 vs 0.8%, p < 0.01) and who underwent laparotomy (12.2 vs 0.4%, p < 0.01). Conclusion Patients who underwent laparoscopy with < 50% myometrial invasion and low-grade tumors not only have higher detection rates, but also have lower false negative rates. These patients may avoid systemic lymphadenectomy according to the status of the SLN biopsy.

Abstract
The aim of this study was to evaluate the dissemination of cancer cells at laparoscopic hysterectomy according to the intraperitoneal cytology.Patients with endometrial cancer underwent total laparoscopic modified radical hysterectomy. Peritoneal wash cytology was performed on entering the peritoneal cavity before surgical preparation and just after hysterectomy.Seventy-eight patients underwent laparoscopic hysterectomy for endometrial cancer. Among the 15 patients who had positive intraperitoneal cytology on entering the peritoneal cavity, 10 converted to negative intraperitoneal cytology after hysterectomy. In contrast, among the 63 patients who had negative intraperitoneal cytology on entering the peritoneal cavity, 2 converted to positive intraperitoneal cytology after hysterectomy.While surgery can reduce the number of cancer cells in the peritoneal cavity, leakage can occur, as seen in some cases of hysterectomy. Careful washing must be performed after hysterectomy.

Indocyanine Green versus Radiotracer with or without Blue Dye for Sentinel Lymph Node Mapping in Stage >IB1 Cervical Cancer (>2 cm). J Minim Invasive Gynecol 2017; 24:954-959. [PMID: 28571944 DOI: 10.1016/j.jmig.2017.05.011] [Citation(s) in RCA: 35] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2017] [Revised: 05/09/2017] [Accepted: 05/10/2017] [Indexed: 11/25/2022]
Abstract
STUDY OBJECTIVE To compare sentinel lymph node (SLN) mapping in women with cervical cancer stage >IB1 (tumor size >2 cm) using indocyanine green (ICG) versus the standard technique using radioisotope technetium 99m radiocolloid (Tc99m) radiotracer with or without blue dye. DESIGN European multicenter, retrospective observational study (Canadian Task Force classification II-2). SETTING Four academic medical centers. PATIENTS Ninety-five women with stage IB1 cervical cancer (>2 cm) who underwent SLN mapping with Tc99m with or without blue dye or ICG and radical hysterectomy. INTERVENTION The detection rate and bilateral mapping rate were compared between ICG and standard Tc99m radiotracer with or without blue dye. Lymphadenectomy was performed, and the false-negative rate was assessed. MEASUREMENTS AND MAIN RESULTS Forty-seven patients underwent SLN mapping with Tc99m with or without blue dye, and 48 did so with ICG. All patients underwent radical hysterectomy with or without bilateral salpingo-oophorectomy between 2008 and 2016. The overall detection rate of SLN mapping was 91.5% for Tc99m with or without blue dye and 100% for ICG. A 91.7% rate of bilateral migration was achieved for ICG, significantly higher than the 66% obtained with Tc99m with or without blue dye (p = .025). Nine of the 23 SLN-positive patients (39.1%) were diagnosed exclusively as a result of the ultrastaging used to identify micrometastases or isolated tumor cells only. CONCLUSIONS In advanced cervical cancer (stage IB1 >2 cm), the detection rate and bilateral migration rate on real-time fluorescent SLN mapping were higher with ICG than with Tc99m radiotracer with or without blue dye. SLN mapping and ultrastaging can provide additional information for nodal staging in advanced cervical cancer. In this setting, ICG is a promising tool for mapping, appearing less affected by higher disease stage compared with traditional methods.
