Abstract
PURPOSE Depiction of pelvic lymph node metastasis (LNM) sites among patients with cervical cancer facilitates accurate determination of the extent of dissection and radiotherapy regimens. METHODS A retrospective study of 1182 cervical cancer patients who underwent radical hysterectomy and pelvic lymph node dissection between 2008 and 2018 was performed. The number of removed pelvic lymph nodes and metastasis status in different anatomical regions was analyzed. The prognostic difference of patients with lymph node involvement stratified by various factors was analyzed by Kaplan-Meier method. RESULTS The median number of pelvic lymph nodes detected was 22, mainly from obturator (29.54%) and inguinal (21.14%) sites. Metastatic pelvic lymph nodes were found in 192 patients, with obturator accounting for the highest percentage (42.86%). The patients with lymph node involvement in single site had better prognosis that those in multiple sites. The overall- (P = 0.021) (OS) and progression-free (P < 0.001) survival (PFS) curves of patients with inguinal lymph node metastases were worse compared to those with obturator site. There was no difference in the OS and PFS among patients with 2 and more than 2 lymph nodes involvement. CONCLUSION An explicit map of LNM in patients with cervical cancer was presented in this study. Obturator lymph nodes tended to be involved. The prognosis of patients with inguinal lymph node involvement was poor in contrast to that with obturator LNM. In patients with inguinal lymph node metastases, clinical staging needs to be reconsidered and extended radiotherapy to the inguinal region needs to be strengthened.

Abstract
Simple Summary Cervical cancers is a human papillomavirus infection-induced gynecologic cancer. Due to the uneven access to prevention measures in the world, it is still a leading cause of cancer death in women in low- and middle-income countries. The mainstay of treatment for early-stage cervical cancers is upfront surgery. Clinical trials confirmed the place of adjuvant radiotherapy to improve disease control, but also highlighted the need for a careful selection of patients prior to surgery, in order to avoid the cumulative morbidities of each treatment. In locally advanced cervical cancers, the standard of care remains concurrent pelvic chemoradiotherapy followed by an image-guided adaptive brachytherapy boost allowing for dose escalation and leading to a very high probability of local control. Systemic failures remain a major concern, and neoadjuvant or adjuvant approaches in this context are discussed in the light of recent literature. Abstract Globally, cervical cancers continue to be one of the leading causes of cancer-related deaths. The primary treatment of patients with early-stage disease includes surgery or radiation therapy with or without chemotherapy. The main challenge in treating these patients is to maintain a curative approach and limit treatment-related morbidity. Traditionally, inoperable patients are treated with radiation therapy solely and operable patients undergo upfront surgery followed by adjuvant (chemo) radiotherapy in cases with poor histopathological prognostic features. Patients with locally advanced cervical cancers are treated with concurrent chemoradiotherapy followed by an image-guided brachytherapy boost. In these patients, the main pattern of failure is distant relapse, encouraging intensification of systemic treatments to improve disease control. Ongoing trials are evaluating immunotherapy in locally advanced tumours following its encouraging efficacy reported in the recurrent and metastatic settings. In this article, clinical evidence of neoadjuvant and adjuvant treatments in cervical cancer patients is reviewed, with a focus on potential strategies to improve patients’ outcome and minimize treatment-related morbidity.

Abstract
Background We aimed to establish an effective 2-deoxy-2-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) based nomogram for pelvic lymph node (PLN) metastasis prediction in early-stage uterine cervical squamous cell cancer. Methods A predictive model was developed in a cohort that consisted of 351 patients with stage IB-IIA [International Federation of Gynecology and Obstetrics (FIGO) 2009] uterine cervical squamous cell cancer. All patients underwent a preoperative PET/CT scan and subsequent radical surgery between 2010 and 2017, with 241 and 110 patients allotted into training and external validation cohorts. The chi-square (χ2) test and the logistic regression analysis were used to compare the clinical and PET/CT parameters with PLN metastasis. A nomogram was developed and validated by internal and external validation. Results In the training cohort, 82 (34.0%) patients had positive PLNs identified in the preoperative PET/CT scan. Among them, 46 (56.1%) were pathologically confirmed. There were 30 (18.9%) PET/CT scan-negative patients found to have PLN metastasis. The χ2 test and logistic regression showed that only the squamous cell carcinoma antigen (SCCA) level (P=0.039) and maximum standardized uptake value (SUVmax) of PLN (nSUVmax, P=0.001) were independent predictors for PLN metastasis. A predictive nomogram based on these 2 parameters was developed with a C-index [95% confidence interval (CI)] of 0.854 (0.772-0.937) on internal validation and 0.836 (0.723-0.948) on the external validation. Compared to nSUVmax alone, our nomogram showed elevated sensitivity (70.5%, 73.1% vs. 60.5%), specificity (94.4%, 86.4% vs. 78.2%), and positive predictive value (PPV) (93.9%, 86.4% vs. 56.1%) in both the training and validation cohorts. Conclusions We successfully developed a noninvasive and convenient nomogram for preoperative identification of PLN metastasis in early-stage squamous cell cervical cancer.

Abstract
The spatial distribution of lymph node (LN) metastasis was analyzed to provide data for an evidence-based approach to radiotherapy field design, particularly for guiding intensity-modulated radiation therapy. A total of 1886 postoperative patients were retrospectively reviewed. Pelvic LNs were classified as common iliac nodes, external iliac nodes, internal iliac nodes/obturator nodes, and deep inguinal nodes. The distribution of LN metastasis in these subgroups was calculated, and the distribution patterns of LN metastasis according to the pathologic types were investigated.We identified 392 eligible patients with LN metastasis. The frequency and number of external iliac node metastasis were higher in the left side in both single subgroup (P < .01) and cosubgroup (P = .04) analyses, whereas few differences were found in other subgroups. Among patients with squamous cell carcinoma, left external iliac node metastasis was observed in 102 (15.13%) patients, whereas right metastasis was observed in 65 (9.64%) patients, and the difference was significant (P < .01).The present results indicated uneven distribution of LN metastasis in the different subgroups, which could help surgeon focus on the dissection of the left subgroups, and help oncologists define margins, refine target volumes for radiation, and improve the accuracy of postoperative radiotherapy especially in patients with squamous cell carcinoma.

Abstract
OBJECTIVE To evaluate the clinical diagnostic validity of carbon nanoparticle suspension (CNS) in sentinel lymph node biopsy (SLNB) for assessing lymphatic spread of early-stage cervical cancer. DESIGN A prospective study. SETTING AND POPULATION 356 cases. METHODS We enrolled 356 stage Ia2-IIa2 cervical cancer patients to undergo SLNB using CNS, followed by systematic pelvic lymphadenectomy. All lymph node specimens were assessed using conventional histopathologic ± pathologic ultrastaging analyses. MAIN OUTCOME MEASURES Sentinel lymph node detection rate (DR), clinical diagnostic validity and various related factors were analysed. RESULTS CNS identified 1456 SLNs in 325 patients. The overall SLN DR was 91.29%. A significantly higher DR was found for patients with tumours <20 mm (97.75% versus 71.91%; P < 0.001). Two patients had false-negative results. SLNB with CNS had sensitivity of 96.65%, false-negative rate (FNR) of 4.35% and negative predictive value (NPV) of 99.29%. Importantly, sensitivity (100%), NPV (100%) and FNR (0%) were improved when testing the subgroup of patients with tumours <20 mm (267 cases). There were no observed differences in DR based on pathological type or grade, stage, depth of stromal invasion, surgical approach, menopausal status or prior treatment with chemotherapy (P > 0.05). CONCLUSIONS Sentinel lymph node biopsy with CNS results in favourable DR, sensitivity and NPV for women with early-stage cervical cancer with small tumour sizes. SLNB with CNS is safe, feasible and relatively effective for guiding precise surgical treatment of early-stage cervical cancer. TWEETABLE ABSTRACT Sentinel lymph node biopsy with carbon nanoparticle suspension is safe and feasible for early-stage cervical cancer.

Abstract
The data on the prognostic significance of low volume metastases in lymph nodes (LN) are inconsistent. The aim of this study was to retrospectively analyze the outcome of a large group of patients treated with sentinel lymph node (SLN) biopsy at a single referral center. Patients with cervical cancer, stage T1a-T2b, common tumor types, negative LN on preoperative staging, treated by primary surgery between 01/2007 and 12/2016, with at least unilateral SLN detection were included. Patients with abandoned radical surgery due to intraoperative SLN positivity detected by frozen section were excluded. All SLNs were postoperatively processed by an intensive protocol for pathological ultrastaging. Altogether, 226 patients were analyzed. Positive LN were detected in 38 (17%) cases; macrometastases (MAC), micrometastases (MIC), isolated tumor cells (ITC) in 14, 16, and 8 patients. With the median follow-up of 65 months, 22 recurrences occurred. Disease-free survival (DFS) reached 90% in the whole group, 93% in LN-negative cases, 89% in cases with MAC, 69% with MIC, and 87% with ITC. The presence of MIC in SLN was associated with significantly decreased DFS and OS. Patients with MIC and MAC should be managed similarly, and SLN ultrastaging should become an integral part of the management of patients with early-stage cervical cancer.

Abstract
The quality of pathological assessment is crucial for the safety of patients with cervical cancer if pelvic lymph node dissection is to be replaced by sentinel lymph node (SLN) biopsy. Central pathology review of SLN pathological ultrastaging was conducted in the prospective SENTIX/European Network of Gynaecological Oncological Trial (ENGOT)-CX2 study. All specimens from at least two patients per site were submitted for the central review. For cases with major or critical deviations, the sites were requested to submit all samples from all additional patients for second-round assessment. From the group of 300 patients, samples from 83 cases from 37 sites were reviewed in the first round. Minor, major, critical, and no deviations were identified in 28%, 19%, 14%, and 39% of cases, respectively. Samples from 26 patients were submitted for the second-round review, with only two major deviations found. In conclusion, a high rate of major or critical deviations was identified in the first round of the central pathology review (28% of samples). This reflects a substantial heterogeneity in current practice, despite trial protocol requirements. The importance of the central review conducted prospectively at the early phase of the trial is demonstrated by a substantial improvement of SLN ultrastaging quality in the second-round review.

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
Metastatic nodal involvement is a critical prognostic factor in uterine cervical cancer (UCC). To improve current methods of detecting UCC metastases in lymph nodes (LNs), we used quantitative PCR (qPCR) to assess mRNA expression of potential metastatic biomarkers. We found that expression of HPV16-E6, cytokeratin19 (CK19), and mucin1 (MUC1) is consistently upregulated in tumors and metastatic tissues, supporting a role for these genes in UCC progression. These putative biomarkers were able to predict the presence of histologically positive metastatic LNs with respective sensitivities and specificities of 82% and 99% (CK19), 76% and 95% (HPV16-E6), and 76% and 78% (MUC1). While the biomarkers failed to detect 1.7% to 2.2% of the histologically positive LNs when used individually, combining CK19 and HPV16-E6 enhanced sensitivity and specificity to 100% and 94%, respectively. To explore the sensitivity of qPCR-based detection of varying proportions of invading HPV16-positive UCC cells, we designed a LN metastasis model that achieved a fresh cell detection limit of 0.008% (1:12500 HPV16-positive to HPV16-negative cells), and a paraffin-embedded, formalin-fixed (PEFF) detection limit of 0.02% (1:5000 HPV16-positive to HPV16-negative cells), both of which are within the theoretical detection limit for micrometastasis. Thus, HPV E6/E7 oncogenes may be useful targets for the ultrasensitive detection of nodal involvements like micrometastases in fresh or archived tissue samples. Moreover, our results suggest that the biomarker combination of CK19/HPV-E6 could support a real-time intraoperative strategy for the detection of small, but potentially lethal, metastatic nodal involvements in fresh UCC tissues.

Abstract
Background: Cervical cancer is the second most common type of cancer among women. Effective screening programs can help
cancer detection in early phases and reduce death. Metastasis to lymph nodes is one of the most prognostic factors in patients who
underwent surgery. Also, a positive result from pathology report alert oncologist as a cause of death. Sentinel lymph node biopsy has
been widely studied and clinically used for many types of cancer.
Methods: Two techniques exist for detecting sentinel node in cervical cancer, which are Blue dye and gamma probe with radioactive
isotope (99mTc). Moreover, lymphoscintigraphy has many advantages over the stain method. Detecting the sentinel node is performed
via laparoscopy or laparotomy; former method is better and more accurate.
Results: Various researchers have focused on this method and its positive results; its superiority against full lymphadenectomy has
been declared in previous studies. Moreover, the role of sentinel lymph nodes biopsy in cervical cancer is still being extensively studied.
Sentinel lymph nodes (SLN) method has a higher accuracy level to detect metastasis.
Conclusion: Hence, it can be considered as a more appropriate alternative for pelvic lymph node dissection (PLND), which is a
standard technique. Altering the method to a standard clinical method needs in-depth researches and studies.

Abstract
Abstract
BACKGROUND: Elevated serum cancer antigen 125 (CA-125) is observed in some cervical cancers (CCs). Is the correlation of CA-125 with the presence of nodal events useful in predicting early metastasis to the lymph nodes?
METHODS: The study included 45 patients with CC FIGO (2009) stages IA1-IIA1 and known preoperative CA-125 concentration, surgery treated (05.2011-05.2014). Investigated pretreatment: age (pre-, postmenopausal), histological type, grade, confounding factors - prior cone biopsy, ovarian cyst, endometriosis, liver or colon pathology, concomitant malignancy. LN metastases (LNM) were defined as macro (MAC, >2mm) and/or micrometastases (mic, 0.2 - 2 mm), and LVLND as mic or/and ITC (single CC cells clusters) in LNs. Ultrastaging of all LNs (sentinel and non-sentinel, 4 μm thick slices/150 μm intervals) was performed with hematoxylin and eosin staining and with immunohistochemistry (IHC - AE1/AE3 cytokeratin antibodies). Non-parametrical analysis and receiver operating curve analysis were used to determine correlation between CA-125 and LNM including LVLND.
RESULTS: The median age was 55 (23-71). 806 LNs were extracted. LNM was found in 12, LVLND in 6 patients. LNM but not LVLND was correlated with higher grade (G2-G3, p<0.05). LVLND was positively correlated with premenopausal age (p<0.05) but not with tumor histology or grade. Liver disease only was found to influence CA-125 levels (p=0.064). There were no differences within CA-125 concentration among LVLND, LNM, and node-negative patients groups, however a trend was found between higher CA-125 and lower LVLND risk.
CONCLUSIONS: Elevated levels of CA-125 may be less likely due to LVLND than to LN positivity. Grade is an important feature in prediction of LNM but not LVLND. CA-125 level was found to be not predictive of LNM nor LVLND, as confirmed by ultrastaging.

Abstract
We performed a meta-analysis to assess the accuracy of sentinel-lymph-node (SLN) procedures for the assessment of nodal metastases in patients with early stage cervical cancer. Studies of SLN procedures for detecting nodal metastases in patients with early stage cervical cancer were systematically searched in MEDLINE and EMBASE between January 1, 2000 and August 30, 2013. We identified 49 eligible studies, which included 2,476 SLN procedures. The mean overall weighted-detection rate was 0.93 (95 % CI 0.92–0.94), at a pooled sensitivity of 0.88 (95 % CI 0.84–0.90) with limited heterogeneity (χ2 = 80.57, degrees of freedom = 47, p = 0.002). Subgroup analysis of sensitivity and the rate of detection of different tracer techniques and surgery methods used in conjunction with an SLN procedures were as follows: studies using combined techniques, 0.88 (95 % CI 0.84–0.91) and 0.97 (95 % CI 0.96–0.98); studies using metastable technetium-99, 0.87 (95 % CI 0.78–0.93) and 0.90 (95 % CI 0.87–0.93); studies using blue dye, 0.87 (95 % CI 0.79–0.93) and 0.87 (95 % CI 0.84–0.90); studies using laparotomy, 0.86 (95 % CI 0.80–0.90) and 0.87 (95 % CI 0.83–0.91); studies using laparoscopy, 0.90 (95 % CI 0.86–0.94) and 0.93 (95 % CI 0.90–0.96); and studies using robot-assisted surgery, 0.84 (95 % CI 0.72–0.92) and 0.92 (95 % CI 0.88–0.95). We concluded that the SLN procedure performs well diagnostically for the assessment of nodal metastases in patients with early stage cervical cancer.

Value and advantages of preoperative sentinel lymph node imaging with SPECT/CT in cervical cancer. Int J Gynecol Cancer 2014; 24:295-302.

Abstract
OBJECTIVE Precise detection of sentinel lymph nodes (SLNs) seems to be a crucial factor for optimized treatment of cervical cancer. We assess the use of single photon emission computed tomography combined with computed tomography (SPECT/CT) as an alternative to lymphoscintigraphy (LSG) for preoperative identification of SLN. METHODS This study was performed in a prospective, unicentric setting. Patients with cervical carcinoma were scheduled for surgery and additional SLN labeling by peritumoral injection of 10 MBq technetium-99m-nanocolloid and patent blue. Thirty minutes after injection, LSG and SPECT/CT were carried out. We evaluated the number of SLNs detected intraoperatively in LSG and SPECT/CT and the histologic findings of SLN and non-SLN. Subsequently, we determined the impact of these results on the therapeutic approach. RESULTS This represents the largest study about SPECT/CT for SLN detection in cervical cancer so far. Between August 2008 and March 2013, 59 cervical cancer patients underwent intraoperative SLN detection. In addition, 51 of these patients underwent preoperative LSG and SPECT/CT. Imaging with SPECT/CT detected singular SLN at significantly higher rate (47/51, 92.2%) than that with planar LSG (43/51, 84.3%, P = 0.044). Furthermore, SPECT/CT performed better than LSG regarding the total number of detected SLN (SPECT/CT median, 3 [0-18]; LSG median, 2 [0-15]) and detection rates per pelvic side (SPECT/CT 76.9%, LSG 69.2%, P < 0.01). Whenever SLN detection succeeded, histologic evaluation of SLN correctly predicted the lymph node status per patient's side. Using this type of diagnostic approach for lymph node staging, we reached sensitivity of 100% and negative predictive value of 100% at a rate of false-negative results of 0% even in tumors larger than 4 cm. CONCLUSIONS Single photon emission computed tomography combined with computed tomography imaging leads to improved rates of SLN detection and better anatomic correlation compared with planar LSG. Thus, intraoperative detection of SLN can be improved by preoperative SPECT/CT imaging. This enhances the clinical value of SLN technique and improves the oncologic safety of SLN concept.

Abstract
The status of regional lymph nodes is the most important prognostic factor in early cervical cancer patients. Pelvic lymph node dissections are routinely performed as a part of standard surgical treatment. Systematic pelvic lymphadenectomy is associated with short- and long-term morbidities. This review discusses single components of the sentinel lymph node mapping (SLNM) technique and results of the detection of sentinel lymph nodes. SLNM biopsy performed by an experienced team for small volume tumors (<2 cm) has high specific side detection rate, excellent negative-predictive value and high sensitivity. Uncommon lymphatic drainage has been reported in 15% of cervical cancer patients. There is sufficient data now to suggest that SLNM with 99mTc plus blue dye in the hands of a surgeon with extensive experience should prove to be an important part of individualized cervical cancer surgery and increase the safety of less radical or fertility-sparing surgery.

Abstract
Sentinel lymph node biopsy has been widely studied in a number of cancer types. As far as cervical cancer is concerned, this technique has already been used, revealing both positive results and several issues to be solved. The debate on the role of sentinel lymph node biopsy in cervical cancer is still open although most of the studies have already revealed its superiority over complete lymphadenectomy and the best handling possible of the emerging practical problems. Further research should be made in order to standardize this method and include it in the clinical routine.

Abstract
To address the value of qRT-PCR and IHC in accurately detecting lymph node micrometastasis in gynecological cancer, we performed a systematic approach, using a set of dual molecular tumor-specific markers such as cytokeratin 19 (CK19) and carbonic anhydrase 9 (CA9), in a series of 46 patients (19 with cervical cancer, 18 with endometrial cancer, and 9 with vulvar cancer). A total of 1281 lymph nodes were analyzed and 28 were found positive by histopathology. Following this documentation, 82 lymph nodes, 11 positive and 71 negative, were randomly selected and further analyzed both by IHC and qRT-PCR for CK19 and CA9 expression. All 11 (100%) expressed CK19 by IHC, while only 6 (54.5%) expressed CA9. On the contrary, all the histologically negative for micrometastases lymph nodes were also negative by IHC analysis for both markers. The comparative diagnostic efficacy of the two markers using qRT-PCR, however, disclosed that the analysis of the same aliquots of the 82 lymph nodes led to 100% specificity for the CK19 biomarker, while, in contrast, CA9 failed to recapitulate a similar pattern. These data suggest that qRT-PCR exhibits a better diagnostic accuracy compared to IHC, while CK19 displays a consistent pattern of detection compared to CA9.

Accuracy of intraoperative pathological examination of SLN in cervical cancer. Gynecol Oncol 2013; 130:525-9. [PMID: 23500089 DOI: 10.1016/j.ygyno.2013.01.023] [Citation(s) in RCA: 41] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2012] [Revised: 01/17/2013] [Accepted: 01/24/2013] [Indexed: 11/20/2022]
Abstract
OBJECTIVE Early cervical cancer patients with pelvic lymph node metastasis do not benefit from radical hysterectomy. Assessment of the SLN status is thus crucial before deciding to perform a radical hysterectomy as opposed to aortic dissection only followed by definitive radiation therapy. Accuracy of frozen section of SLN has been questioned and deserves further investigation. METHODS Stage IA-IB1 cervical cancer patients who underwent SLN then full pelvic dissection at the Claudius Regaud Cancer Center in Toulouse, France, were included. RESULTS At least one SLN was identified in all 94 patients. Bilateral detection rate was 80.8%. Ectopic drainage area was found in 19 patients (20.2%). Sentinel lymph node involvement was found in 11 patients (11.7%). Sensitivity and NPV of frozen section pathological examination for the detection of macrometastatic disease was 100%, sensitivity for the detection of macro and micrometastatic disease, excluding ITC, was 88.9%, and NPV was 98.8%. Micrometastasis and isolated tumor cells (ITC) undetected at frozen section examination were found in 1 patient (1.06%) and 2 lymph nodes (1.24%), and in 2 patients (2.13%) and 2 lymph nodes (1.24%), respectively. Final pathology sensitivity of SLN was 100% for both macro and micrometastatic disease, including ITC. CONCLUSION In our institution, intraoperative frozen examination of SLN accurately predicts the status of pelvic lymph nodes and is effective for selecting intraoperatively the group of patients who benefit from radical hysterectomy. In addition, our results suggest that patients with small tumors and bilateral detection of SLN can be spared full pelvic lymphadenectomy.

Abstract
The superior prognostic value offered by routine histopathological staging of neck dissections, as compared to clinical staging using palpation and modern imaging techniques, is well established in the literature concerning the management of squamous cell carcinoma of the head and neck. In this review, we discuss the definitions and criteria used in standardised routine histopathological reporting and explore additional potential nodal prognostic features. In addition, we critically appraise the value of immunohistochemistry, histochemistry, molecular and other non-morphological techniques and suggest tumour and host features that merit further investigations.

Abstract
OBJECTIVE To evaluate the sensitivity of sentinel node (SN) ultrastaging and to define parameters that may reduce the overall false-negative rate in women with early-stage cervical cancer. METHODS We analyzed data from a large retrospective multicenter cohort group with FIGO stages IA-IIB cervical cancer in whom at least one SN was identified and systematic pelvic lymphadenectomy was uniformly performed. All who were SN negative by initial evaluation were subjected to ultrastaging. RESULTS In all, 645 patients were evaluable. SN were detected bilaterally in 72% of cases and unilaterally in 28%. Patients with optimal bilateral SN detection were significantly more likely to have any metastasis detected (33.3% vs. 19.2%; P<0.001) as well as micrometastasis detected in their SN (39.6% vs. 11.4%). SN ultrastaging resulted in a low overall false-negative rate of 2.8% (whole group) and an even lower false-negative rate of 1.3% for patients with optimal bilateral mapping. Patients with false-negative SN after ultrastaging had a higher prevalence of LVSI and more frequent unilateral SN detection. Sensitivity of SN ultrastaging was 91% (95% CI: 86%-95%) for the whole group and 97% (95% CI: 91%-99%) in the subgroup with bilateral SN detection. CONCLUSION These data confirm previous observations that optimal bilateral SN detection substantially decreases the false negative rate of SN ultrastaging and increases detection of micrometastasis. In patients with bilateral SN detection, the sensitivity of SN ultrastaging is not reduced in more advanced stages of the disease. SN mapping and ultrastaging should become standard practice in the surgical management of early-stage cervical cancer.

Abstract
Objective: Assess the role of planar lymphoscintigraphy and fusion imaging of SPECT/CT in sentinel lymph node (SLN) detection in patients with gynecologic tumours. Material and Methods: Planar scintigraphy and hybrid modality SPECT/CT were performed in 64 consecutive women with gynecologic tumours (mean age 53.6 with range 30-77 years): 36 pts with cervical cancer (Group A), 21 pts with endometrial cancer (Group B), 7 pts with vulvar carcinoma (Group C). Planar and SPECT/CT images were interpreted separately by two nuclear medicine physicians. Efficacy of these two techniques to image SLN were compared. Results: Planar scintigraphy did not image SLN in 7 patients (10.9%), SPECT/CT was negative in 4 patients (6.3%). In 35 (54.7%) patients the number of SLNs captured on SPECT/CT was higher than on planar imaging. Differences in detection of SLN between planar and SPECT/CT imaging in the group of all 64 patients are statistically significant (p<0.05). Three foci of uptake (1.7% from totally visible 177 foci on planar images) in 2 patients interpreted on planar images as hot LNs were found to be false positive non-nodal sites of uptake when further assessed on SPECT/CT. SPECT/CT showed the exact anatomical location of all visualised sentinel nodes. Conclusion: In some patients with gynecologic cancers SPECT/CT improves detection of sentinel lymph nodes. It can image nodes not visible on planar scintigrams, exclude false positive uptake and exactly localise pelvic and paraaortal SLNs. It improves anatomic localization of SLNs. Conflict of interest:None declared.

Abstract
OBJECTIVE Evaluate prognostic significance of low volume disease detected in sentinel nodes (SN) of patients with early stages cervical cancer. Although pathologic ultrastaging of SN allows for identification of low volume disease, including micro-metastasis and isolated tumor cells (ITC), in up to 15% of cases, prognostic significance of these findings is unknown. METHODS A total of 645 records from 8 centers were retrospectively reviewed. Enrolled in our study were patients with early-stage cervical cancer who had undergone surgical treatment including SN biopsy followed by pelvic lymphadenectomy and pathologic ultrastaging of SN. RESULTS Macrometastasis, micrometastasis, and ITC were detected by SN ultrastaging in 14.7%, 10.1%, and 4.5% patients respectively. False negativity of SN ultrastaging reached 2.8%. The presence of ITC was not associated with significant risk, both for recurrence free survival and overall survival. Overall survival was significantly reduced in patients with macrometastasis and micrometastasis; hazard ratio for overall survival reached 6.85 (95% CI, 2.59-18.05) and 6.86 (95% CI, 2.09-22.61) respectively. Presence of micrometastasis was an independent prognostic factor for overall survival in a multivariable model. CONCLUSION Presence of micrometastasis in SN in patients with early stage cervical cancer was associated with significant reduction of overall survival, which was equivalent to patients with macrometastasis. No prognostic significance was found for ITC. These data highlight the importance of SN biopsy and pathologic ultrastaging for the management of cervical cancer.

Abstract
PURPOSE In cervix carcinoma: (a) to evaluate the ability of ((18)F)-fluorodeoxyglucose (FDG) positron emission tomography (PET) in the lymph node detection; (b) to investigate the prognostic and predictive value of the primary cervical PET parameters. PATIENTS AND METHODS Ninety patients treated for cervix carcinoma and evaluated initially by MRI and FGD PET were included. The performances of FDG-PET for lymph node detection (relatively to the lymph node dissection) have been described (sensitivity, specificity, positive predictive value and negative predictive value). PET tumour parameters analyzed were: maximum standard uptake value (SUVmax), the volume and the maximum diameter. The prognostic and predictive values of these parameters were investigated. The tumour response was evaluated on surgical specimens. RESULTS PET detected the cervical tumour with a sensitivity of 97% (mean values: SUVmax=15.8, volume=27 mm(3), maximum diameter=47). For the detection of the lymph nodes, the values of sensibility, specificity, positive predictive value and negative predictive value were: 86, 56, 69 and 78% in the pelvic, and 90, 67, 50 and 95% for the para-aortic area, respectively. The SUVmax was correlated with histologic response (P=0.04). The frequency of partial histological response was significantly higher for tumour SUVmax>10.9 (P=0.017). The maximum PET diameter and pathologic response had an impact on disease-free survival and overall survival in multivariate analysis (P<0.05). CONCLUSION PET has high sensitivity in detecting pelvic and para-aortic lymph nodes. Some primary cervical tumour PET parameters are useful as prognostic and predictive factors.

Abstract
Background Lymphadenectomy is debated in early stages endometrial cancer. Moreover, a new FIGO classification of endometrial cancer, merging stages IA and IB has been recently published. Therefore, the aims of the present study was to evaluate the relevance of the sentinel node (SN) procedure in women with endometrial cancer and to discuss whether the use of the 2009 FIGO classification could modify the indications for SN procedure. Methods Eighty-five patients with endometrial cancer underwent the SN procedure followed by pelvic lymphadenectomy. SNs were detected with a dual or single labelling method in 74 and 11 cases, respectively. All SNs were analysed by both H&E staining and immunohistochemistry. Presumed stage before surgery was assessed for all patients based on MR imaging features using the 1988 FIGO classification and the 2009 FIGO classification. Results An SN was detected in 88.2% of cases (75/85 women). Among the fourteen patients with lymph node metastases one-half were detected by serial sectioning and immunohistochemical analysis. There were no false negative case. Using the 1988 FIGO classification and the 2009 FIGO classification, the correlation between preoperative MRI staging and final histology was moderate with Kappa = 0.24 and Kappa = 0.45, respectively. None of the patients with grade 1 endometrioid carcinoma on biopsy and IA 2009 FIGO stage on MR imaging exhibited positive SN. In patients with grade 2-3 endometrioid carcinoma and stage IA on MR imaging, the rate of positive SN reached 16.6% with an incidence of micrometastases of 50%. Conclusions The present study suggests that sentinel node biopsy is an adequate technique to evaluate lymph node status. The use of the 2009 FIGO classification increases the accuracy of MR imaging to stage patients with early stages of endometrial cancer and contributes to clarify the indication of SN biopsy according to tumour grade and histological type.

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
PURPOSE OF REVIEW In early-stage vulvar, cervical and endometrial cancer, lymph node status is the most important prognostic factor. Surgical treatment is aimed at removing the primary tumor and adequately staging the regional lymph nodes. As morbidity of regional lymphadenectomy is high, sentinel node biopsy is a technique with potential for adequate staging with less treatment-related morbidity. This manuscript reviews its current role in vulvar, cervical and endometrial cancer. RECENT FINDINGS In early-stage vulvar cancer, level 3 evidence indicates that it appears to be safe to omit inguinofemoral lymphadenectomy in case of a negative sentinel node. However, false-negative results with fatal consequences do occur and are often attributable to procedural failures. For early-stage cervical cancer, level 3 evidence points to an acceptable false-negative rate of a negative sentinel node; clinical utility and safety remain to be established. The optimal technique of the sentinel node biopsy in endometrial cancer is currently unclear. SUMMARY In early-stage vulvar cancer, data suggest that sentinel node biopsy could be offered as a treatment option instead of routine inguinofemoral lymphadenectomy. However, more (long-term follow-up) data are needed to further appreciate real clinical benefits. It is emphasized that the procedure should be performed by a skilled multidisciplinary team, centralized in oncology centers and preferably within the protection of clinical trials. For cervical cancer, data are promising, but routine application cannot be recommended due to lack of data on clinical utility and safety. For endometrial cancer, studies on the sentinel node biopsy are still in feasibility stage.

Abstract
OBJECTIVE Diagnosis of lymph node metastasis is a critical issue in the treatment of cervical cancer. Many studies describing sentinel node navigation surgery (SNNS) for examination of node status have been reported in the past decade. In this study, the feasibility of node status diagnosis by SNNS, including intraoperative frozen section diagnosis, in patients with early and advanced cervical cancer was evaluated. PATIENTS AND METHODS Fifty-eight cervical cancer patients with early and advanced stage disease were enrolled. All patients were treated with backup pelvic lymphadenectomy after SNNS. To detect sentinel lymph nodes (SLNs), radioactive material and/or blue dye were used as tracers. Lymph nodes confirmed as SLNs were immediately sent to pathologists and diagnosed by frozen section intraoperatively. RESULTS A total of 118 and 16 SLNs were pathologically investigated in early and advanced stage cervical cancer, respectively. The detection rate of SLNs in the early and advanced stages was 94.7% and 66.7%, respectively, whereas the detection rate using 1 or 2 tracers was 62.5% and 90%, respectively. The false-negative rate and negative predictive value was 0% and 100% for all stages. Pathological diagnosis by frozen section was completed within 30 minutes in all cases. CONCLUSIONS Our data demonstrate that SNNS in cervical cancer is a promising procedure for patients with early stage (up to Ib1) disease, especially patients with small tumor diameter (<2.0 cm). However, SNNS raises several points for discussion before it can be established as a practical clinical procedure or as part of a subsequent radical hysterectomy.

Abstract
Lymph-nodal involvement is a major prognostic factor of cervical cancer. Lymph-node status is classically evaluated by lymph-node dissection. This surgical approach has mainly a prognostic interest. The morbidity related to the lymph-node dissection is not nil, so numerous imaging or surgical techniques have been recently developed in order to reduce this morbidity. Currently, even with the progress of the imaging techniques, surgical lymph-node dissection is the standard approach. For the management of early cervical cancer, surgery is usually the sole treatment. In association with a laparoscopic lymph-node dissection, the sentinel node technique is a new approach that gives interesting data: possibility of performing frozen sections on the sentinel nodes in order to improve the management, discovery in an important proportion of cases of abnormal lymphatic pathways that are a potential aetiology of recurrence, and identification of lymph-node micrometastases that seem to be an important independent prognostic factor. In the future, evaluation of only the sentinel nodes may replace the pelvic lymph-node dissection. For advanced cervical cancers, the treatment is based on chemoradiotherapy. The paraaortic lymph-node status is an important prognostic factor that helps for defining the radiotherapy fields. New imaging techniques as PET Scan, may help for the evaluation of paraaortic lymph-node status. If the PET Scan is positive at the paraaortic level, there is no need for paraaortic lymph-node dissection and radiotherapy should be performed with pelvic and abdominal fields. But the false negative rate of the PET Scan is high and laparoscopic paraaortic lymph-node dissection is required in case of negative PET Scan at the paraaortic level.
