Laparoscopic identification of sentinel lymph node in treatment of invasive cervical cancer

The fundamental prognostic factor in treatment of early cervical cancer is the state of regional lymph nodes. If the first lymphatic node is involved by cancer, the other ones may be affected; otherwise if the first one is free of metastatic cells, the others should not be involved by cancer either. Detection and removal of the lymphatic node called the sentinel lymph node permit to avoid radical lymphadenectomy which is connected with many severe complications. We reported a technique of identification of the sentinel lymph node during laparoscopic radical hysterectomy with pelvic lymphadenectomy in treatment of early invasive cervical cancer with presentation of case history. Identification of sentinel node with its histopathology examination may be essential in women with cervical cancer and potentially identifies women in whom lymph node dissection can be avoided. Laparoscopic lymphadenectomy seems to be equally effective and less invasive in comparison to traditional technique.     

The role of sentinel lymph node biopsy in early-stage cervical cancer: A systematic review

Pelvic lymphadenectomy procedure is included as part of the standard protocol of radical hysterectomy for women with early-stage cervical cancer (Stage IA to IB1). However, an important sequel to lymphadenectomy procedure is the possible occurrence of lymphedema in the lower abdomen and lower extremities. Previous researches also find that women with lymphedema experience many emotional impacts, including depression, anxiety, and adjustment problems. Only approximately 10% of women with clinical stage IB cervical carcinoma were involved with metastatic disease. If we could better define the relevant lymphatic nodes that must be removed, it is then possible to limit routinely performed lymphadenectomy for regional nodal metastasis in the pelvis, and hence reduce the need for extended surgical staging (para-aortic lymphadenectomy). We systematically reviewed a body of literature and updated available information concerning the current progress on the application of sentinel lymph node biopsy in women with early-stage cervical cancer. All detection methods (preoperative injection of radiocolloid tracer, intraoperative injection of blue dye, or a combination of both techniques) demonstrated reasonable sensitivity (with a few exceptions), high specificity, low false-negative rate and high negative predictive value. The review of the literature in this paper should convince the readers that sentinel lymph node biopsy has the potential to improve the quality of life and the possibility to maintain relapse-free survival for women with cervical cancer. The proper identification of negative sentinel lymph node allows individualized therapy and may preclude the need of lymphadenectomy procedure in most of these women.     

Contribution of the sentinel node procedure to tailoring the radicality of hysterectomy for cervical cancer

OBJECTIVE: The required radicality of hysterectomy for women with early-stage cervical cancer is controversial owing to the risk of severe complications. The aim of this study was to determine the contribution of the sentinel node (SN) procedure to tailoring the radicality of hysterectomy in women with cervical cancer. METHODS: Between April 2001 and December 2005, 54 patients with early-stage or locally advanced cervical cancer underwent laparoscopic sentinel node (SN) biopsy based on combined patent blue and radiocolloid detection. Thirty-nine patients with early-stage cervical cancer underwent a laparoscopic SN procedure with complete pelvic lymphadenectomy and radical hysterectomy. Moreover, 15 women with locally advanced cervical cancer underwent an SN procedure with pelvic and para-aortic lymphadenectomy before concurrent neoadjuvant chemoradiotherapy. RESULTS: The SN detection rate was 83.3%. The detection rate was higher in women with early-stage disease (90%) than in women with more advanced disease (66.6%) (p=0.03). At final histology, 14 metastatic SN were found in 11 (21.3%) of the 54 patients. They comprised macrometastases in 6 SN, micrometastases in 5 SN, and isolated tumour cells in 3 SN. Parametrial involvement with negative sentinel nodes was found in 15.1% of cases. The overall sensitivity, specificity, positive and negative predictive values and accuracy of intraoperative imprint cytology were 20%, 100%, 100%, 79.5% and 80.5%, respectively. Among the 39 women with early cervical cancer, five (12.8%) had parametrial involvement. In univariate analysis, parametrial involvement was significantly associated with large tumour size, advanced-stage disease, positive pelvic lymph nodes and lymphovascular space involvement. Parametrial involvement tended to be associated with positive sentinel nodes. CONCLUSION: These results underline the contribution of the SN procedure to evaluating lymph node status. However, intraoperative imprint cytology appeared poorly accurate, and further histological or biological tools are needed to evaluate SN status and, hence, to tailor the radicality of hysterectomy.     

Laparoscopic sentinel lymph nodes identification followed by trachelectomy in early stage cervical cancer

The status of regional lymph nodes is the main prognostic factor in diagnosis and treatment of early stage of the cervical cancer. If the first node that drains a tumor site (sentinel node) is not metastatic, other lymph nodes should also be free of the disease. Detection using blue dye and laparoscopic removal of the sentinel lymph nodes let to avoid radical hysterectomy with pelvic limphadenectomy and it is especially useful in young women who want to preserve fertility. We describe a case of a 33- year old woman with invasive cervical cancer who underwent laparoscopic sentinel lymph nodes detection followed by trachelectomy. Thus histopatological examination confirmed no metastasis in removed sentinel lymph nodes, trachelectomy as a minimally invasive procedure was performed.     

Sentinel Lymph Node Evaluation in Women with Cervical Cancer

Lymph node status is the most important prognosticator of survival in women with early stage cervical cancer. Thus many patients with cervical cancer will undergo pelvic lymphadenectomy as part of the treatment. This procedure is associated with substantial morbidity. Use of the sentinel lymph node technique in women with cervical cancer has the potential to decrease this morbidity. Multiple studies have suggested that sentinel lymph node mapping in these patients is feasible, with excellent detection rates and sensitivity. This review examines the current body of literature about sentinel lymph node biopsy in women with cervical cancer.     

Intraoperative sentinel node identification in early stage cervical cancer using a combination of radiolabeled albumin injection and isosulfan blue dye injection

OBJECTIVES: We investigated the feasibility of sentinel lymph node identification using radioisotopic lymphatic mapping with technetium-99m-labeled human serum albumin and isosulfan blue dye injection in patients undergoing radical hysterectomy with pelvic lymphadenectomy for treatment of early cervical cancer. METHODS: Between September 2000 and October 2002, 25 patients with cervical cancer FIGO stage I (n=24) or stage II (n=1) underwent sentinel lymph node detection with preoperative lymphoscintigraphy (technetium-99m colloid albumin injection around the tumor) and intraoperative lymphatic mapping with blue dye and a handheld or laparoscopic gamma probe. Complete pelvic or paraaortic lymphadenectomy was performed in all cases by open surgery or laparoscopic surgery. RESULTS: In 23 evaluable patients, a total of 51 sentinel lymph nodes were detected by lymphoscintigraphy (mean 2.21 nodes per patient). Intraoperatively, 61 sentinel lymph nodes were identified, with a mean of 2.52 nodes per patient by gamma probe and a mean of 1.94 nodes per patient after isosulfan blue injection. Forty percent of sentinel nodes were found in the interiliac region and 25% in the external iliac area. Microscopic nodal metastases (four nodes) were confirmed in 12% of cases. All these lymph nodes were previously detected as sentinel lymph nodes. The remaining 419 nodes after pelvic lymphadenectomy were histologically negative. CONCLUSIONS: Sentinel lymph node identification with technetium-99m-labeled nanocolloid combined with blue dye injection is feasible and showed a 100% negative predictive value, and potentially identified women in whom lymph node dissection can be avoided.     

HPV status in sentinel nodes might be a prognostic factor in cervical cancer

OBJECTIVE: Although there have been studies that focused on the correlation between the HPV presence of pelvic lymph nodes and pathological metastasis in patients with cervical cancer, the biologic role of HPV DNA in lymph nodes still remains uncertain. We performed this study to investigate the correlation between the sentinel-node HPV status and pelvic lymph node metastasis in patients with cervical cancer. The patients were followed up for 3 years to evaluate the clinical role of HPV in sentinel nodes as a prognostic factor. METHODS: From August 2001 to July 2003, 57 patients affected by stages IB-IIA cervical cancer had sentinel-node biopsies performed during radical hysterectomy and pelvic and paraaortic lymphadenectomy. Each detected sentinel node was divided into two parts. One part of them was submitted for frozen section examination and the other was submitted for HPV typing by oligonucleotide microarray. After follow-up, we analyzed the outcome of the patients with respect to the influence of sentinel-node HPV. RESULTS: Sentinel nodes were identified in all patients. A total of 79 nodes from 57 patients were detected as sentinel nodes. Metastasis in the sentinel nodes were found in 10 patients (17.6%) by frozen section and 11 patients by pathologic examination. The results of sentinel lymph node frozen biopsy were statistically significant for predicting the metastasis of the pelvic lymph nodes (P<0.05), but showed one false-negative case. HPV DNA was detected in the cervical cancer lesions of 55 patients (96.5%) and 80.0% (44/55) of them were found to have HPV DNA in the sentinel nodes as well. HPV DNA was detected in sentinel nodes of 10 patients among 11 patients with lymph node metastasis. Disease recurred in five patients and one of them did not show pelvic lymph node metastasis at surgery. But, all of these patients had HPV in sentinel nodes. The combination of sentinel-node frozen biopsy and HPV typing showed a negative predictive value of 100% in predicting non-metastasis of lymph node and no recurrence of disease. CONCLUSION: Our results suggested the possibility that sentinel-node HPV typing could play a supportive role to reduce the false-negative rate of the sentinel-node biopsy. All of five patients with recurrence had HPV infection in the sentinel nodes. Absence of HPV in sentinel nodes showed reliable negative predictive value for lymph node metastasis and recurrence. Additional study will be needed to confirm the clinical application of the sentinel-node procedure and to determine whether there is a correlation of HPV status of sentinel nodes to lymph node metastasis and recurrence in cervical cancer patients.     

Value of indocyanine green pelvic lymph node mapping in the surgical approach of cervical cancer

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. 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. 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. 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. This trial is registered within the German Clinical Trial Register (DRKS-ID: DRKS00014692).     

Sentinel node detection in cervical cancer with (99m)Tc-phytate

OBJECTIVES: The aim of this study was to investigate the feasibility of sentinel lymph node (SLN) identification using radioisotopic lymphatic mapping with technetium-99 m-labeled phytate in patients undergoing radical hysterectomy with pelvic lymphadenectomy for treatment of early cervical cancer. METHODS: Between July 2001 and February 2003, 56 patients with cervical cancer FIGO stage I (n = 53) or stage II (n = 3) underwent sentinel lymph node detection with preoperative lymphoscintigraphy ((99m)Tc-labeled phytate injected into the uterine cervix, at 3, 6, 9, and 12 o'clock, at a dose of 55-74 MBq in a volume of 0.8 ml) and intraoperative lymphatic mapping with a handheld gamma probe. Radical hysterectomy was aborted in three cases because parametrial invasion was found intraoperatively and we performed only sentinel node resection. The remaining 53 patients underwent radical hysterectomy with complete pelvic lymphadenectomy. Sentinel nodes were detected using a handheld gamma-probe and removed for pathological assessment during the abdominal radical hysterectomy and pelvic lymphadenectomy. RESULTS: One or more sentinel nodes were detected in 52 out of 56 eligible patients (92.8%). A total of 120 SLNs were detected by lymphoscintigraphy (mean 2.27 nodes per patient) and intraoperatively by gamma probe. Forty-four percent of SLNs were found in the external iliac area, 39% in the obturator region, 8.3% in interiliac region, and 6.7% in the common iliac area. Unilateral sentinel nodes were found in thirty-one patients (59%). The remaining 21 patients (41%) had bilateral sentinel nodes. Microscopic nodal metastases were confirmed in 17 (32%) cases. In 10 of these patients, only SLNs had metastases. The 98 sentinel nodes that were negative on hematoxylin and eosin were submitted to cytokeratin immunohistochemical analysis. Five (5.1%) micrometastases were identified with this technique. The sensitivity of the sentinel node was 82.3% (CI 95% = 56.6-96.2) and the negative predictive value was 92.1% (CI 95% = 78.6-98.3). The accuracy of sentinel node in predicting the lymph node status was 94.2%. CONCLUSION: Preoperative lymphoscintigraphy and intraoperative lymphatic mapping with (99m)Tc-labeled phytate are effective in identifying sentinel nodes in patients undergoing radical hysterectomy and to select women in whom lymph node dissection can be avoided.     

Sentinel lymph node biopsy in endometrial cancer—Feasibility,safety and lymphatic complications

Objective

To compare the rate of lymphatic complications in women with endometrial cancer undergoing sentinel lymph node biopsy versus a full pelvic and infrarenal paraaortic lymphadenectomy, and to examine the overall feasibility and safety of the former.

Sentinel node detection with radiocolloid lymphatic mapping in early invasive cervical cancer

We assessed the feasibility of sentinel lymph node detection using technicium-99 radiocolloid lymphatic mapping for predicting lymph node metastases in early invasive cervical cancer. Thirty patients with cervical cancer (stages IA2-IIA) underwent preoperative lymphoscintigraphy using technicium-99 intracervical injection and intraoperative lymphatic mapping with a handheld gamma probe. After dissection of the sentinel nodes, the standard procedure of pelvic lymph node dissection and radical hysterectomy was performed as usual. The sentinel node detection rate was 100% (30/30). There were seven (23.3%) cases of microscopic lymph node metastases on pathologic analysis. All of them had sentinel node involvement. Therefore, the sensitivity of sentinel node identification for prediction of lymph node metastases was 100%, and no false negative was found. Preoperative lymphoscintigraphy, coupled with intraoperative lymphatic mapping, located the sentinel nodes accurately in our study patients. This sentinel node detection method appears to be feasible for predicting lymph node metastases.     

Sentinel lymph node in endometrial cancer: an overview

The role of complete pelvic and para-aortic lymphadenectomy in early endometrial cancer remains controversial in gynecologic oncology. Sentinel lymph node detection is an alternative to assess lymphatic spread in several solid tumors. The authors review the literature related to the detection of sentinel lymph node in endometrial cancer, the techniques employed, and its results and feasibility. The authors review reported case series of endometrial cancer in which the sentinel lymph node biopsy was performed. A systematic literature review was conducted using the PubMed database. Different techniques were used considering lymphatic imaging mapping (colorimetric, isotopic, and fluorescence procedures) and injection site (subserous, hysteroscopic, and cervical). Detection rates of sentinel lymph node were heterogeneous, varying between 44 and 100 % with false-negative rates between 0 and 33 %. Although technically demanding, hysteroscopy approach was associated with the highest detection rate. The largest trials showed a good detection rate with cervical injection, a more reproducible procedure. The laparoscopic route improved the results. Immunohistochemistry staining improved the micrometastasis detection in sentinel lymph node. Cost-effectiveness of systematic lymphadenectomy compared with sentinel lymph node procedure and its value on adjuvant therapies as well as a standardized reproducible and reliable technique must be assessed.     

Sentinel lymph node procedure and uterine cancers

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

Role of lymphadenectomy in ovarian cancer

The exact role of lymphadenectomy in the management of ovarian cancer has been the object of controversy during recent years. The International Federation of Obstetrics and Gynecology has indicated that pelvic and para-aortic lymph node sampling is an integral part of the staging system of ovarian cancer. On the other hand the advantage of systematic sampling, resection of bulky nodes only, or no lymphadenectomy in terms of recurrence rate and survival of ovarian cancer patients has not yet been clearly defined. Thanks to the analysis of clinical studies on systematic lymphadenectomy, detailed anatomical studies to assess the location of lymph nodes and lymphatic spread have been recently reported.In this chapter we report the available data on clinical anatomy and pathological assessment of lymph node and lymphatic spread of ovarian cancer metastasis; we also review the clinical data on correlation of lymph node metastasis and disease status. Surgical techniques developed during years of dedication to this procedure are also described. Finally, we review and discuss the actual benefits of lymph node dissection in patients with ovarian cancer, analysing previously reported and ongoing trials.

Sentinel node identification and intraoperative lymphatic mapping. First results of a pilot study in patients with endometrial cancer

INTRODUCTION: To minimize the surgical morbidity after lymphadenectomy, sentinel node biopsy (SLNB) has become fundamental in the management of different malignancies. We decided to evaluate sentinel lymph node (SNL) biopsies also in patients with endometrial cancer undergoing hysterectomy with lymphadenectomy. METHODS: In the setting of a prospective study we developed a technique for sentinel node biopsy of ten patients with histologically confirmed endometrial cancer. Prior to surgery 99m Tc Nanocol was injected in the peritumoral region by hysteroscopy. Six hours later lymphoscintigraphy was performed to identify the draining lymph nodes. During surgery we first detected the sentinel lymph node by a hand-held gamma tracer and then removed it. Surgery was completed by the standard therapy of total hysterectomy, bilateral salpingo-oophorectomy and pelvic and/or para-aortic lymphadenectomy. RESULTS: Scintigraphic identification was possible in eight out of ten patients. Intraoperative identification of sentinel lymph nodes was possible in seven out of eight patients. In five patients we found the sentinel lymph nodes in the pelvic region while the other two patients had bilateral sentinel nodes in the pelvic and para-aortic region. Histologically confirmed microscopic tumor metastases of the SLNs and para-aortic lymph nodes were only found in one case. The sentinel lymph nodes from the other six patients were free of tumor and accurately reflected the pathological status. CONCLUSION: The identification of sentinel lymph nodes in endometrial cancer is a practical and safe method. In order to improve this technique as a standard procedure for staging of endometrial cancer further studies with a larger number of patients have to be done.     

早期宫颈癌患者保留生育功能的治疗策略研究进展

广泛全子宫切除术和盆腔淋巴结切除术仍然是年轻早期宫颈癌患者治疗的常规术式,患者因此丧失生育能力。本文针对国内外最新研究进展,回顾性分析宫颈癌根治术后宫旁、阴道旁及淋巴结转移情况,发现早期宫颈癌患者中仅27%存在淋巴结转移,并对前哨淋巴结切除术的临床应用前景以及为保留生育功能而进行“最小而有效的”手术治疗方式的研究现状进行总结讨论。前哨淋巴结切除术可提高术中诊断淋巴结转移与否的准确度,减少不必要的过度治疗,目前有替代盆腔淋巴结切除术的趋势。目前保留生育功能的手术主要有6种术式,即扩大宫颈锥切术、单纯宫颈切除术、经阴道广泛性宫颈切除术、开腹广泛性宫颈切除术、腹腔镜下广泛性宫颈切除术和机器人辅助腹腔镜下广泛性宫颈切除术。对于病灶＞2 cm的患者,推荐先行新辅助化疗（NACT）3~4个疗程后,再结合妇科检查及影像学证据,选择宫颈切除范围和具体术式。     

Lymphatic mapping and sentinel node biopsy in women with high-risk endometrial cancer

OBJECTIVE: To evaluate fundal injection of blue dye and radiocolloid for lymphatic mapping and sentinel node identification in women with high-risk endometrial cancer. METHODS: At laparotomy, 18 women with high-risk endometrial cancer had isosulfan blue and technitium-99 radiocolloid injected into the uterine fundus subserosally. Sentinel nodes were then identified either by direct observation of blue dye, by radioactive counts using a handheld gamma counter, or by a combination of both methods. The number and location of sentinel node(s) were recorded and compared with the final lymph node specimens after hysterectomy and selective lymphadenectomy. RESULTS: A sentinel node was identified in only 8 (45%) of the cases. Four patients had sentinel nodes only in the pelvis, 2 had sentinel nodes in the pelvis and above the bifurcation of the aorta, and 2 patients had sentinel nodes above the bifurcation of the aorta only. Seven (88%) patients had unilateral drainage of dye and the radiocolloid; the other patient had bilateral drainage. No patients had metastatic disease to sentinel or nonsentinel lymph nodes. CONCLUSIONS: Subserosal fundal injection of blue dye and the radiocolloid is a poor technique for identifying sentinel lymph nodes in patients with high-risk endometrial cancer.     

Intraoperative lymphatic mapping in cervix cancer patients undergoing radical hysterectomy: A pilot study

OBJECTIVE: Intraoperative lymphatic mapping and sentinel lymph node identification (SLN) have been increasingly evaluated in the treatment of a variety of solid tumors, particularly breast cancer and melanoma. We sought to evaluate the feasibility of these procedures in patients undergoing radical hysterectomy with pelvic lymphadenectomy for treatment of early cervical cancer. METHODS: Twenty patients with normal-appearing lymph nodes underwent intracervical injection of isosulfan blue dye (lymphazurin 1%) at the time of planned radical hysterectomy and bilateral pelvic/low paraortic lymphadenectomy (40 nodal basins). Regional lymphatic tissue was inspected for dye uptake into lymphatic channels and lymph nodes. Tumor characteristics, surgical findings, and specific locations of lymphatic dye uptake were recorded and correlated with final pathology results. RESULTS: Sentinel lymph nodes were identified in 12 of 20 (60%) patients. A total of 23 sentinel nodes were identified in 17 of 40 (43%) nodal basins dissected (range: 0-2 per basin). Successful SLN identification was less likely in patients with tumors >4 cm compared with those with tumors 相似文献   

Is common iliac lymph node dissection necessary in early stage cervical carcinoma?

OBJECTIVES: Nodal metastasis is one of the most important prognostic factors in early stage cervical carcinoma and has an immense impact on the subsequent management. Thus, searching for nodal metastasis by pelvic lymphadenectomy is an integral part in the surgical management of cervical carcinoma. Complete nodal clearance of lymphatic tissue up to 2 cm above the bifurcation of common iliac vessels is therefore performed as a routine in our unit. The aim of this study is to investigate the incidence and pattern of pelvic lymph node metastases in patients with early stage cervical carcinoma to determine the role of common iliac node dissection in the surgery. METHODS: We retrospectively reviewed 174 operation and histopathology reports of patients who underwent pelvic lymphadenectomy because of stage IA2 to IIA cervical carcinoma. Lymph nodes collected below and above the bifurcation of common iliac vessels were labeled as pelvic nodes and common iliac nodes, respectively. The incidence and distribution of nodal metastases were analyzed. RESULTS: Complete and selective pelvic lymphadenectomy was performed in 163 and 11 patients, respectively. Nodal metastasis was documented in 35 (20.1%) patients. Pelvic and common iliac nodes were involved in 34 and 8 cases, respectively. All except one patient with common iliac node metastases were also found to have pelvic node metastasis. CONCLUSIONS: In early stage cervical carcinoma, isolated common iliac lymph node metastasis is rare, especially in cases without associated high risk factors. Less extensive pelvic lymphadenectomy may be considered in these patients in order to reduce operation morbidity and time.
