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
The presence of pelvic lymph node metastases is without doubt the most significant prognostic factor that determines recurrences and survival of women with early-stage cervical cancer. To avoid the underdiagnosis of lymph node metastasis, pelvic lymphadenectomy procedure is routinely performed with radical hysterectomy procedure. However, the pelvic lymphadenectomy procedure may not be necessary in most of these women due to the relatively low incidence of pelvic lymph node metastasis. The removal of large numbers of pelvic lymph nodes could also render non-metastatic irreversible damages for these women, including vessel, nerve, or ureteral injuries; formation of lymphocysts; and lymphedema. Over the past decades, the concept of sentinel lymph node biopsy has emerged as a popular and widespread surgical technique for the evaluation of the pelvic lymph node status in gynecologic malignancies. The histological status of sentinel lymph node should be representative for all other lymph nodes in the regional drainage area. If metastasis is non-existent in the sentinel lymph node, the likelihood of metastatic spread in the remaining regional lymph nodes is very low. Further lymphadenectomy is therefore not necessary for a patient with negative sentinel lymph nodes. Since the uterine cervix has several lymphatic drainage pathways, it is a challenging task to assess the distribution pattern of sentinel lymph nodes in women with early-stage cervical cancer. This review article will adapt the methodology proposed in these studies to systematically review sentinel lymphatic mapping among women with early-stage cervical cancer.

Abstract
Purpose To evaluate patterns of lymph flow from primary lesions in patients with cervical cancer and to determine how useful for radiotherapy planning this information can be. Materials and methods SPECT-CT visualization of sentinel (SLN) lymph nodes (LNs) was performed in 36 primary patients with IB-IIB cervical cancer. The acquisition started 120-240 min after 4 peritumoral injections of 99mTc-radiocolloids (150-300 MBq in 0.4-1 ml). We determined localization of LN with uptake of radiocolloids, type of lymph flow (mono-, bi-lateral) and lymph flow patterns (supraureteral paracervical, infraureteral paracervical and directly to para-aortic LNs). Results SLNs were visualized in 31 of 36 women. Bilateral lymph-flow was detected in 22 (71%), monolateral - in the other 9 (29%) cases. The distribution of SLNs was as follows: external iliac - 64.5%, internal iliac - 54.8%, obturator - 32.2%, common iliac - 35.5% and pre-sacral 3.2%. Para-aortic LNs were visualized in 5 (16.1%) patients. The supraureteral paracervical pattern of lymph flow was identified in 22, infraureteral paracervical - in 4 and their combination - in the other 5 women. Conclusion Visualization of an individual pattern of lymph flow from primary cervical cancer can be considered as a promising tool for optimization of the volume of irradiated regional LNs.

Abstract
The intraoperative mapping of sentinel lymph nodes (SLNs) is part of the treatment strategy for a number of types of tumor. To retrospectively compare results from the mapping of pelvic SLNs for gynecological oncology, using distinct dyes, the present review was conducted to determine the clinical significance of SLN mapping for gynecological oncology. In addition, the present study aimed at identifying an improved choice for SLN mapping tracers in clinical application. Each dye exhibits demerits when applied in the clinical environment. The combination of radioisotopes and blue dyes was identified to exhibit the most accurate detection rate of SLN drainage of gynecological oncology. However, contrast agents were unable to identify whether a SLN is positive or negative for metastasis prior to pathologic examination; additional studies are required.

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.

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
Sentinel lymph node biopsy (SLNB) is used to determine the pathological status of the first lymph node receiving lymphatic drainage from the primary tumor. The diagnostic value of SLNB for the assessment of the nodal status in patients with cervical cancer has not been determined. Therefore, this meta-analysis was conducted to assess the diagnostic value of SLNB in cervical cancer. A search for related literature was performed using PubMed. Data were analyzed using a random effects model and a subgroup analysis was used to assess the diagnostic value of different practices during the process. A total of 17 studies involving a total of 1,112 patients were included in the analysis. The pooled sentinel lymph node (SLN) detection rate, sensitivity and negative predictive values were 92.2% [95% confidence interval (CI): 88.3-94.8%], 88.8% (95% CI: 85.1-91.7%) and 95.0% (95% CI: 92.8-96.6%), respectively. The subgroup analysis revealed that laparoscopy, tracer combination and immunohistochemistry were associated with a higher SLN detection rate. In conclusion, the SLNB in cervical cancer appears to be of diagnostic value, particularly the procedure with the combination of laparoscopy, combined tracers and immunohistochemistry. However, further studies are required to establish the clinical value of SLNB in 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 The aim of this study was to systematically determine the frequency of unusual localizations of sentinel lymph node in patients with early stage cervical cancer. METHODS We performed a comprehensive computer literature search of English and French language studies in human subjects on sentinel node procedures in PUBMED database up to December 2010. For each article two reviewers independently performed data extraction using a standard form to determine the route of unusual lymphatic spread of sentinel procedures in cervical cancer. RESULTS According to our search, 83.7% of detected sentinel lymph nodes in patients with cervical cancer were in expected localizations (i.e., external iliac, obturator, internal iliac or interiliac). The unusual localizations were: 6.6% in the common iliac chain, 4.31% parametrial, 1.26% sacral, 2% in the lower para-aortic area and 0.07% in the inguinal chain. CONCLUSION The unusual localizations of sentinel lymph nodes impose to the gynecologic surgeons to be able to perform lymph node dissection in all the territories potentially affected.

Abstract
UNLABELLED Localization of sentinel lymph nodes can be challenging if they are in difficult anatomic locations or near high radiotracer activity. The purpose of this study was to assess the value of intraoperative real-time imaging using a portable gamma-camera in conjunction with a conventional gamma-counting probe when it is difficult to localize the sentinel node. METHODS After (99m)Tc-nanocolloid injection, patients with various malignancies underwent presurgical lymphoscintigraphy followed by surgery (usually the next day). We evaluated 20 patients who required sentinel lymph node biopsy and in whom the location or other characteristics of the sentinel node would make intraoperative retrieval difficult. During surgery, the sentinel node was localized using a portable gamma-camera together with a hand-held gamma-probe. A (153)Gd pointer or (125)I seed was used to better depict the sentinel node location in real time. RESULTS Using only a conventional hand-held gamma-probe, surgeons were able to definitively localize the sentinel node in 15 of 20 patients. Intraoperatively, the portable gamma-camera showed uptake by the definite sentinel node in 19 of 20 patients and helped to precisely localize the node with the hand-held gamma-probe in 4 patients. In 1 of these patients, the sentinel node was metastatic. CONCLUSION The combination of a standard hand-held gamma-probe and real-time imaging provided by a portable gamma-camera offers a high intraoperative detection rate in patients with difficult sentinel node localization as assessed by presurgical lymphoscintigraphy.

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
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
Background/Aim. Therapy of the early stages of cervical carcinoma is surgical or radiation therapy, and for advanced stages chemoradiotherapy. Pelvic and paraaortic lymphadenectomy in early stages offers the most important prognostic factor for survival. To evaluate the method and possible influence on surgical staging and therapy of the disease, we performed sentinel node (SN) identification and excision during open radical hysterectomy and lymphadenectomy in stage Ib-IIa cervical carcinoma. Methods. Fifty patients initially diagnosed with invasive squamous-cell cervical cancer stage Ib-IIa were included in the study. Only blue dye was used for sentinel node mapping. During the surgery sentinel nodes were identified and sent to histopathology separately from the other lymph nodes. After lymphadenectomy, radical hysterectomy was performed. Results. The mean age of our fifty patients was 49.10 years (SD = 5.92), and the mean number of extracted lymph nodes per patient was 25.78 (SD = 5.58). The number of sentinel nodes identified per patient was between 0 and 5, mean 2.60 (SD = 1.54). There were no inframesenteric paraaortic sentinel nodes found among the patients. The dominant tumor grades were 1 and 2, 40% and 50% respectively, and 37 out of 50 patients (74%) had tumor diameter less than 2 cm. In four patients (8%) SN were not identified. In the rest of 46 patients the presence of SN was bilateral (19 patients, 38%) or unilateral (27 patients, 54%). Positive SN were found in 17 patients (34%), and negative in 29 patients (58%). Out of the whole group of patients (50), 21 of them (42%) had positive lymph nodes (LN). In the crosstab statistics, no differences were noticed in the group without SN found, in comparison with tumor grade and diameter. Finally, our test showed sensitivity of 85% (SE = 8%), specificity 100%, positive predictive value of 100%, negative predictive value of 89.6% (SE = 5.6%), and effectiveness of 93% (SE = 3.6%) regarding sentinel lymphadenectomy. Conclusion. This method of sentinel lymph node identification is simple, but not reliable enough to support further laparoscopic SN excision in order to make the final decision about the treatment of cervical cancer.

Abstract
The technique of sentinel lymph node (SLN) detection is increasingly being applied in patients with uterine cervix carcinoma. This study presents the pathologic findings of SLNs in 48 such patients. The institutional pathology files were searched for all patients with a diagnosis of cervical squamous cell carcinoma who had SLNs reported. Patient age, follow-up, tumor size, presence/absence of lymphatic invasion, number and status of SLNs and non-SLNs, location of SLNs, and size of metastases in SLNs were recorded. All SLNs were sectioned in 2-mm slices perpendicular to the long axis and submitted entirely for microscopic examination. For all SLNs negative on the initial hematoxylin and eosin (H&E) stained slides, an ultrastaging protocol was performed consisting of 5 sets of slides at 40-mum intervals (1 H&E slide+2 unstained slides), representing an additional 5 intervals. Lymph nodes negative by the additional H&E intervals had immunohistochemistry for cytokeratin performed on 1 unstained slide. Forty-eight patients ranging from 25 to 62 years of age had a total of 208 SLNs removed. Fifteen (31%) patients had positive SLNs with 1 to 5 positive SLNs per case. The metastasis size ranged from a single cell to 27 mm. Twelve patients had metastasis detected by routine processing in 23 SLNs, whereas ultrastaging detected metastases in 3 SLNs of 3 additional patients. In 2 patients with metastasis detected by ultrastaging, the metastasis was detected by wide H&E intervals (level 2 for 1 patient; level 3 for 1 patient); in 1 patient, the metastasis was detected only by immunohistochemistry and consisted of a single cell. Of the 15 patients with positive SLNs, 3 patients had a total of 6 positive non-SLNs. All of the patients with a positive SLN are currently living. Thirty-three (69%) patients had negative SLNs. Of these, 1 patient had a single positive non-SLN for a false negative rate of 6.25%. Negative SLN predicts negative non-SLN. For most patients with a positive SLN, the SLN will be the only metastasis detected; a minority of patients with a positive SLN may have a positive non-SLN.

Abstract
BACKGROUND It has been suggested that histologically undetectable or 'occult' metastases in the lymphatic system could explain some recurrences. HPV DNA screening by means of the polymerase chain reaction (PCR) has been proposed as a method to detect occult metastases. This study was designed to determine the frequency of HPV DNA detection by PCR in sentinel lymph node (SN), and its relation to the clinical characteristics and outcome of women with cervical cancer. PATIENTS AND METHODS The primary cervical tumor and SN were tested for HPV DNA by means of PCR in 59 patients. RESULTS Fifteen (25.4%) of the 59 women undergoing the SN procedure had an involved SN. HPV DNA was more frequent in positive SN than in negative SN (P < 0.0001). Seven patients had a recurrence, after a mean delay of 17 months (range: 10-26). One of seven patients with a recurrence had an involved SN. HPV DNA was detected in an SN of one of seven patients with recurrence and nine (19.5%) of 46 patients without recurrence (not significant). CONCLUSION In women with cervical cancer, HPV DNA screening of sentinel nodes might help to identify patients at risk of lymph node metastases and recurrence.

Gynecol Oncol 2007; 106:604-13. [PMID: 17628644 DOI: 10.1016/j.ygyno.2007.05.010] [Citation(s) in RCA: 132] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2007] [Revised: 04/20/2007] [Accepted: 05/07/2007] [Indexed: 01/29/2023]
Abstract
OBJECTIVE The aim of this study was to systematically review the diagnostic performance of Sentinel Node (SN) detection for assessing the nodal status in early stage cervical carcinoma, and to determine which technique (using blue dye, Technetium-99m colloid (99mTc), or the combined method) had the highest success rate in terms of detection rate and sensitivity. METHODS A comprehensive computer literature search of English language studies in human subjects on Sentinel Node procedures was performed in MEDLINE and EMBASE databases up to July 2006. For each article two reviewers independently performed a methodological qualitative analysis and data extraction using a standard form. Pooled values of the SN detection rate and pooled sensitivity values of the SN procedure are presented with a 95% confidence interval (95% CI) for the three different SN detection techniques. RESULTS We identified 98 articles, and 23 met the inclusion criteria, comprising a total of 842 patients. Ultimately, 12 studies used the combined technique with a sensitivity of 92% (95% CI: 84-98%). Five studies used 99mTc-colloid, with a pooled sensitivity of 92% (95% CI: 79-98%; p=0.71 vs. combined technique), and four used blue dye with a pooled sensitivity of 81% (67-92%, p=0.17 vs. combined technique). The SN detection rate was highest for the combined technique: 97% (95% CI: 95-98%), vs. 84% for blue dye (95% CI: 79-89%; p<0.0001), and 88% (95% CI: 82-92%, p=0.0018) for 99mTc colloid. CONCLUSION SN biopsy has the highest SN detection rate when 99mTc is used in combination with blue dye (97%), and a sensitivity of 92%. Hence, according to the present evidence in literature the combination of 99mTc and a blue dye for SN biopsy in patients with early stage cervical cancer is a reliable method to detect lymph node metastases in early stage cervical cancer.

Abstract
BACKGROUND To evaluate the feasibility after 5 years experience of a laparoscopic sentinel node (SN) procedure with combined radioisotopic and patent blue labeling in patients with cervical cancer. METHODS Sixty-seven patients (median age 48.9 years) with cervical cancer underwent a laparoscopic SN procedure using an endoscopic gamma probe, after both radioactive and patent blue injections. After the procedure, all the patients underwent complete laparoscopic pelvic/para-aortic lymphadenectomy. RESULTS At least one SN was identified in 57 patients (85.1%). According to the Stage, the SN identification rate was 91.2% in early-stage cervical cancer and 78.5% in locally advanced cervical cancer. The mean number of SN was 2.3 per patient (range 1-5). A total of 129 SNs were removed. Lymph node metastasis involvement was identified in the 20 SNs (15.5%) from 14 patients (24.6%). Nine of the 14 patients had at least one macrometastases, three patients presented micrometastases in H&S, and two patients presented isolated single cells. Six patients presented a pelvic non-SN involvement including two patients whose SNs were uninvolved. The false-negative SNs rate was 12.5% (two patients out of 16). Both patients have locally advanced cervical cancer. CONCLUSION This study confirms that laparoscopic SN detection with a combination of radiocolloid and patent blue is accurate in patients with early cervical cancer to assess pelvic lymph node status.

Abstract
OBJECTIVE The significance of negative sentinel lymph nodes (SLN) is important in the staging and treatment of melanoma and a few other cancers, but is controversial in uterine cervix carcinoma. Our study was aimed at correlating the SLN status in cervical carcinoma with non-sentinel lymph nodes (non-SLN), in a uniform and well controlled population. METHODS This study includes 36 patients with stage I and IIA cervical carcinoma and bilaterally negative SLN on final pathology. SLN were identified using blue dye and radioisotopic techniques. Frozen section examination was performed for all SLN; the rest of the tissue was formalin fixed and paraffin embedded. The protocol used for SLN was also applied for non-SLN. For each block, six 4-micro m thick sections were cut at 40 micro m intervals and stained with H and E; an additional section taken between the 3rd and 4th levels was imunostained using AE1/AE3 cytokeratin. RESULTS The mean age for the study population was 39 years (range 25-76); the number of SLN ranged from 2 to 6 (mean 2.7) and the non-SLN from 8 to 49 (mean 23) per case. No metastasis was found in any SLN and non-SLN by step sections and IHC. CONCLUSION Our study demonstrates that bilaterally negative SLN on final pathology accurately predict the absence of metastases in non-SLN in cervical carcinoma. If confirmed by larger trials, these results may influence the clinical management of early cervical cancer.
