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

Abstract
Sentinel node is defined as the first node to receive drainage from a primary tumor and seems to reflect the nodal status in the lymphatic drainage of the tumor. Sentinel node technique has modified the pathological examination of lymph nodes, with intraoperative evaluation of sentinel node, allowing immediate lymph node dissection in case of positive sentinel node, and histological ultrastratification to detect occult metastases. This is a literature review of different histological protocols of sentinel node according to different organs. Except for sentinel node in breast cancer and melanoma, intraoperative examination of sentinel node is helpful using frozen section, more sensitive than touch imprint cytology. Sentinel node should be embedded in paraffin block entirely after gross sectioning at two millimeters intervals parallel to the long axis of the node. Histological ultrastaging with serial sections can be helpful, but the number of sections and the interval between them is not codified. Three sections at 200-250 microns can identify the majority of micrometastases (<2mm and >200 microns). Systematic immunohistochemistry of sentinel node is not necessary for breast cancers, since isolated tumor cells do not modify the therapeutic strategy, but remains useful in other organs.

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
Diagnostic value of hepatic artery perfusion fraction (HAF) combined with transforming growth factor-β (TGF-β) in the diagnosis of primary liver carcinoma (PLC) was evaluated. The clinical data of 128 PLC patients undergoing radical hepatectomy in Affiliated Hospital of Jining Medical University were regarded as the study group. Seventy-four healthy volunteers examined in Affiliated Hospital of Jining Medical University were collected as the control group. Double-antibody sandwich enzyme-linked immunosorbent assay was used to detect the expression level of serum TGF-β. The upper abdomen of the subjects was scanned by a 64-slice spiral CT, and the perfusion parameters were analyzed and calculated. According to the HAF and the expression level of TGF-β in the two groups, single and combined detection of TGF-β and HAF parameters were detected, respectively, by ROC curve. The expression of TGF-β in serum of the study group was higher than that of the control group (P<0.05). The expression level of serum TGF-β was closely related to total bilirubin, ascites, TNM stage, prothrombin time and tumor diameter. Blood flow (BF), blood volume (BV), permeability surface (PS), HAF and other perfusion parameters in the study group were higher than those in the control group (P<0.05). The specificity and sensitivity of TGF-β expression level in diagnosing PLC were 73 and 93%, respectively; the specificity and sensitivity of HAF parameter in diagnosing PLC were 73 and 100%, respectively; the specificity and sensitivity of HAF parameter combined with TGF-β expression level were 84 and 100%, respectively. TGF-β is highly expressed in serum of PLC patients; HAF parameter combined with TGF-β expression level can improve the specificity and has an important value in the diagnosis of PLC, which is worthy of clinical promotion.

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
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
Objective: Detection of lymph node involvement in women with IB2–IIB cervical cancer could have a positive effect on survival. We set out to evaluate the incidence of pelvic and/or para-aortic lymph node involvement using the sentinel node (SN) biopsy and its impact on survival. Methods: From 2002 to 2010, 66 women with IB2–IIB cervical cancer underwent a pelvic and paraaortic lymphadenectomy with SN biopsy. Survival between groups according to lymph node status was evaluated. Results: Mean tumour size was 43.5 mm. At least one SN was detected in 69% of the 45 SN procedures performed. Sixteen of these patients had metastatic SN and the false negative rate was 20%. Metastatic pelvic SNs or non-SNs were detected in 33 patients (50%), including pelvic-positive nodes in 26 (40%), pelvic- and paraaortic-positive lymph nodes in seven (11%), and paraaortic skip metastases in two (6%). Positive paraaortic node was the sole determinant for disease-free survival (DFS) and overall survival (OS; P<0.001). Differences in DFS and OS between groups according to the nodal status were observed (P<0.001). Conclusion: SN procedure gave a higher rate of metastasis detection. Further studies are required to evaluate whether pre-therapeutic node staging, including paraaortic and pelvic lymphanedectomy, should be performed.

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

Abstract
For almost a century abdominal radical hysterectomy has been the standard surgical treatment of early-stage macroscopic carcinoma of the uterine cervix. The excessive parametrial resection of the original procedures of Wertheim, Okabayashi, and Meigs has later been "tailored" to tumor extent. Systematic pelvic and eventually periaortic lymph node dissection is performed to identify and treat regional disease. Adjuvant (chemo)radiation therapy is liberally added to improve locoregional tumor control when histopathological risk factors are present. The therapeutic index of the current surgical treatment, particularly if combined with radiation, appears to be inferior to that of primary chemoradiation as an oncologically equivalent therapeutic alternative. Several avenues of new conceptual and technical developments have been used since the 1990s with the goal of improving the therapeutic index. These are: surgical staging, including sentinel node biopsy and nodal debulking; minimal access and recently robotic radical hysterectomy; fertility-preserving surgery; nerve-sparing radical hysterectomy; total mesometrial resection based on developmentally defined surgical anatomy; and supraradical hysterectomy. The superiority of these new developments over the standard treatment remains to be demonstrated by controlled prospective trials. Multimodality therapy including surgery for locally advanced disease represents another area of clinical research. Both neoadjuvant chemotherapy followed by radical surgery, with or without adjuvant radiation, and completion surgery after (chemo)radiation are feasible and have to be compared to primary chemoradiation as the new nonsurgical treatment standard. Surgical treatment of postirradiation persisting or recurrent cervical carcinoma has been traditionally limited to pelvic exenteration for central disease. Applying the principle of developmentally derived anatomical compartments increases R0 resectability. The laterally extended endopelvic resection allows even the extirpation of a subset of visceral pelvic side wall tumors with clear margins. Many questions regarding the indication for these "ultraradical" operations, the surgery of irradiated tissues, and the optimal reconstructive procedures are still open and demand multi-institutional controlled trials to be answered.

Abstract
Lymph node metastases is a recognized prognostic factor in women with cervical cancer. However, there is a need for consensual histological definition of micrometastases in this indication which could give rise to a classification system similar to that used in breast cancer. We thus conducted a MEDLINE and EMBASE database analysis to evaluate the concept of micrometastases in cervical cancer. Retrospective studies place the incidence of micrometastasis between 1.5 and 15% depending on the technique used to evaluate lymph node status. Sentinel lymph node biopsy with serial sectioning and immunohistochemical analysis appears to be the most accurate micrometastases detection technique. The value of RT-PCR in micrometastases detection remains to be clarified by further studies. From a clinical view point, few data are available to support the prognostic relevance of micrometastases. However, case control and longitudinal studies have underlined the risk of recurrence in women with micrometastases, raising the issue of a revision of adjuvant therapy indications in this specific population.

[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
OBJECTIVE To evaluate the feasibility of sentinel lymph node (SLN) detection in patients with cervical cancer using the low-cost methylene blue dye and to optimize the application procedure. PATIENTS AND METHODS Patients with stage Ib(1)-IIa cervical cancer and subjected to abdominal radical abdominal hysterectomy and pelvic lymphadenectomy were enrolled. Methylene blue, 2-4 ml, was injected into the cervical peritumoral area in 77 cases (4 ml patent blue in the other four cases) 10-360 min before the incision, and surgically removed lymph nodes were examined for the blue lymph nodes that were considered as SLNs. RESULTS High SLN detection rate was successfully achieved when 4 ml of methylene blue was applied (93.9%, 46/49). Bilaterally SLN detection rate was significantly higher (78.1% vs. 47.1% P=0.027) in cases when the timing of application was more than 60 min before surgery than those with timing no more than 30 min. The blue color of methylene blue-stained SLNs sustained both in vivo and ex vivo, compared with the gradually faded blue color of patent blue that detected in 3 of 4 cases unilaterally. In the total of 112 dissected sides, the most common location of SLNs was the obturator basin (65.2%, 73/112), followed by external iliac area (30.4%, 34/112) and internal iliac area (26.8%, 30/112). Three patients who gave false negative results all had enlarged nodes. CONCLUSION Methylene blue is an effective tracer to detect SLNs in patients with early stage cervical cancer. The ideal dose and timing of methylene blue application are 4 ml and 60-90 min prior surgery, respectively.

Abstract
AIMS Sentinel lymph node (SLN) detection is widely practiced in the management of patients with malignant melanoma and beast cancer. Large studies on SLN detection and determination of nodal status have led to changes in the surgical management of the regional lymph nodes in these diseases. More recently attention has focused on other solid cancers, including gynaecological cancers. METHODS An extensive literature review of published reports on the SLN in gynaecological cancers was undertaken and the reports were categorised according to the level of evidence provided. RESULTS Vulva cancer is the most frequently investigated gynaecological cancer with regard to SLN detection because of its anatomical location and easily accessible nodal basin. Although there are no randomised controlled trials, some data suggest SLN detection in vulval cancer may alter clinical practice and reduce the number of groin lymphadenectomies. The lymphatic drainage of the other gynaecological organs is less predictable, the nodal basin less accessible or less well defined, the techniques not standardised and the evidence for the applicability of SLN detection in the management of these cancers is weak. CONCLUSION Sentinel lymph node detection in vulval cancer may reduce the need for radical groin lymphadenectomy and thereby reduce morbidity. SLN detection for other gynaecological cancers has little potential to alter clinical practice.

Abstract
BACKGROUND Since the introduction of the sentinel concept in cervical cancer in 1999, various studies have been demonstrated the feasibility, detection rate and sensitivity and rate of false-negative sentinel lymph nodes (SLN). There are only limited data regarding the mapping of the removed SLN. A correlation between the localization of SLN and the tumor stage, histology or marker substance has never been investigated. METHODS Between 2/2000 and 6/2005, the SLN distribution of 151 patients with histologically confirmed cervical cancer (FIGO stages IA n = 21, IB n = 95, IIA n = 14, IIB n = 18, IIIB n = 2, IVA n = 1), who participated in the ongoing "Uterus 3" sentinel study of the German Association of Gynecologic Oncologists (AGO), was retrospectively analyzed with respect to the histology, tumor stage and detection substance. The tumors comprised mostly of squamous cell carcinomas (75.5%) with a smaller fraction of adenocarcinomas (24.5%). RESULTS Altogether, 406 SLN, an average of 2.7 (1-7) SLN per patient, were removed. More than one SLN was detected in 111 patients (73.5%). SLN were found unilaterally in 70 patients (46.4%) und bilaterally in 81 patients (53.6%). SLN sites were paraaortic in 4%, common iliac in 5%, external iliac in 5%, internal iliac in 8%, interiliac in 71% and parametric in 7%. Irrespective of the detection drug applied, most SLN were interiliac (blue 70%, TC 67%, TC and blue 71%). Combined application of technetium and blue dye revealed significantly more SLN in the paraaotic region (P = 0.006). Adenocarcinomas and squamous carcinomas did not differ in the distribution of SLN (P = 0.205). The majority of SLN are interiliac in all tumor stages (FIGO IA 76%, IB 68%, IIA 61%, IIB 83%, III and IV 88%). CONCLUSIONS Removal of SLN in the external iliac, interiliac and obturator area enables evaluation of more than 80% of all SLN. The pattern of SLN is independent from histology and tumor stage. Combined use of technetium and blue dye detects sentinels more frequently in the paraaortic region than a single marker.

Abstract
BACKGROUND Marjolin ulcers are malignant neoplasia developing in chronic open wounds and pathological scars. A definitive diagnosis is made by histological examination of permanent sections. Frozen section biopsy has been widely used for intraoperative diagnosis and evaluation of surgical excision safety margins. This preliminary study aims to discuss the reliability of a simpler and faster method -- intraoperative cytology -- in the diagnosis of Marjolin ulcers. PATIENTS AND METHODS Touch or scrape smears of 76 Marjolin ulcers from 22 patients were assessed, and features were compared to the histological appearance of permanent sections. RESULTS Cytology revealed squamous cell carcinoma (SCC) in 45 ulcers from 11 patients. Histology confirmed SCC in 48 ulcers from 12 patients. No false-positive and one false-negative results were found. Cytology was found to have a 98.7% accuracy, 98% sensitivity and 100% specificity in the intraoperative diagnosis of Marjolin ulcers. CONCLUSIONS Cytology is a fast and reliable alternative in the intraoperative diagnosis of Marjolin ulcers.

Abstract
The utility of lymphatic mapping and sentinel lymph node biopsy in malignancies of the female lower genital tract-- vulvar, vaginal, and cervical cancers--is being explored in multiple centers internationally. For patients with these tumors, lymphatic mapping with sentinel lymph node biopsy holds the promise of increasing the identification of microscopically metastatic disease while decreasing the morbidity of complete lymphadenectomy. In this review article we present the published data on mapping techniques and discuss the advantages and pitfalls of these procedures.

Abstract
OBJECTIVE To determine the reliability of pretherapeutic laparoscopic pelvic lymphadenectomy in cervical cancer as a function of lymph node recurrences according to initial lymph node status: 1) to establish the false negative rate by analyzing lymph node recurrence in patients N-, 2) to verify treatment adequacy in patients N+ by comparing the rate of node recurrence to initial node positivity. PATIENTS AND METHODS Retrospective analysis of a prospectively registered patient database. One hundred and ninety patients treated by a combination of radiotherapy and surgery for cervical cancer stages 1b to 2b in 95% of cases had undergone, from March 1992 to June 2003, a previous laparoscopic pelvic lymphadenectomy. Median follow-up was 40 months (range: 3-126 months). RESULTS Initial lymph node positivity (N+) was found in 79 patients (42%). Fourteen patients (7.4%) presented with lymph node recurrence, all of whom have died from disease. Lymph node recurrence was found in 4/111 patients N- (3.6%) and in 10/79 patients N+ (12.7%), of whom 8/10 occurred outside the radiation fields. CONCLUSION With a very low false negative rate, accuracy of the laparoscopic pelvic lymphadenectomy in the determination of lymphatic spread in cervical cancer is confirmed. It can still be considered the gold standard despite recent developments (e.g. sentinel lymph node determination) to which they should be compared. Treatment adequacy in patients N+ is confirmed.

Abstract
PURPOSE OF REVIEW Cervical cancer is the second most frequent cancer in women in the world. Surgery plays a major role, particularly in patients with early-stage disease. This review focuses on the evaluation of important papers published since January 2003 on the management of invasive cervical cancer. RECENT FINDINGS Patients are classified as having early-stage (stage IB1) or advanced-stage (stage IB2 or greater) disease. Several papers are devoted to the evaluation of prognostic factors in patients with early-stage disease and negative nodes. Several recurrences after radical trachelectomy have been reported that remind us that strict selection criteria are mandatory for conservative management. The development of sentinel node and laparoscopic procedures has gained momentum. For patients with advanced-stage disease, the place of staging procedures in para-aortic areas or pelvic surgery after chemoradiation therapy continues to be debated and is currently being investigated in randomized studies. Several papers also continue to debate surgical treatment modalities for recurrent disease (the place of laparoscopy and reconstructive surgery). SUMMARY Several interesting papers have been published since 2003 about the surgical treatment of cervical cancer. Laparoscopic surgery and the sentinel node procedure have developed considerably, particularly for the surgical management of early-stage disease. The results of ongoing studies are awaited to determine the value of pelvic surgery (after neoadjuvant treatment) in patients with advanced-stage disease.

Abstract
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.
