Abstract
PURPOSE The aim of this review is to give an overview of the current status of molecular image-guided surgery in gynaecological malignancies, from both clinical and technological points of view. METHODS A narrative approach was taken to describe the relevant literature, focusing on clinical applications of molecular image-guided surgery in gynaecology, preoperative imaging as surgical roadmap, and intraoperative devices. RESULTS The most common clinical application in gynaecology is sentinel node biopsy (SNB). Other promising approaches are receptor-target modalities and occult lesion localisation. Preoperative SPECT/CT and PET/CT permit a roadmap for adequate surgical planning. Intraoperative detection modalities span from 1D probes to 2D portable cameras and 3D freehand imaging. CONCLUSION After successful application of radio-guided SNB and SPECT, innovation is leaning towards hybrid modalities, such as hybrid tracer and fusion of imaging approaches including SPECT/CT and PET/CT. Robotic surgery, as well as augmented reality and virtual reality techniques, is leading to application of these innovative technologies to the clinical setting, guiding surgeons towards a precise, personalised, and minimally invasive approach.

Abstract
INTRODUCTION In early-stage vulvar squamous cell carcinoma (VSCC) a sentinel lymph node (SLN) procedure is regarded successful if at least one SLN is removed with minimal residual radioactivity. An inguinofemoral lymphadenectomy is considered if not all SLNs visualized on lymphoscintigraphy can be found, with subsequent increased morbidity. We correlated lymphoscintigraphy findings with surgical outcome and groin recurrence with focus on number of SLNs found. METHODS This study concerns a retrospective cohort of 171 women treated for early-stage VSCC who underwent a SLN procedure between 2000 and 2020. The risk of groin recurrence was compared after either a successful or complete SLN procedure, i.e. removal of all SLNs that were visualized on lymphoscintigraphy. RESULTS In 13 (7.6%) groins of 171 patients SLN visualization on lymphoscintigraphy failed. In 230 of the 246 (93.5%) groins in which a SLN was visualized, at least one SLN was found during surgery. In 224 of the 246 (91.1%) groins the SLN procedure was regarded either successful (n = 14) or complete (n = 210). An isolated groin recurrence was documented in 5 out of 192 (2.6%, 95%-CI; 0.34 to 4.9) SLN-negative groins after a median follow-up of 47.0 months. All recurrences were noted in the complete SLN group (5/180 groins). The difference with the successful SLN group (0/12 groins) was not significant. CONCLUSION Risk of groin recurrence was 2.6% after SLN negative biopsy in early-stage VSCC. The risk appeared not increased if at least one SLN was found with minimal residual radioactivity, in case more SLNs were visualized on lymphoscintigraphy.

Abstract
OBJECTIVE The objective of this study was to examine the feasibility and success rate of intraoperative injection of radiotracer and blue dye performed by the surgeon without the use of preoperative lymphoscintigraphy for the detection of sentinel lymph nodes in clinically early stage vulvar cancer. METHODS All patients with clinically early stage vulvar cancer who underwent attempted sentinel lymph node biopsy using intraoperative injection of Technetium-99 m (99mTc) tracer and blue dye performed by the surgeon after induction of anesthesia at single academic institution from 12/2009 to 5/2022 were identified. Demographic and clinicopathologic variables were collected. Data were compared using descriptive statistics. RESULTS One hundred sixty-four patients (median age 66.4 years) underwent intraoperative injection of radioactive tracer and dye for sentinel lymph node biopsy. Most patients (n = 156, 95.1%) were white. Squamous cell carcinoma accounted for 138 cases (84.1%), melanoma for 10 (6.1%), extra-mammary invasive Paget's disease for 11 (6.7%), and other histologies for 5 (3%). A majority of cases were stage I disease on final pathology (n = 119, 72.6%). Most patients (n = 117, 71%) had tumors located within 2 cm of the midline and underwent planned bilateral groin assessment, while 47 (29%) had well lateralized lesions and underwent unilateral groin assessment. For the patients undergoing unilateral groin assessment, 44 of 47 (93.6%) had successful unilateral mapping. Of the patients who underwent bilateral groin assessment, 87 of 117 (74.4%) had successful bilateral mapping, and 26 of 117 (22.2%) had successful unilateral mapping. Of the 26 patients who underwent bilateral assessment but only had unilateral mapping, 19 had unilateral mapping to ipsilateral groin but failed contralateral mapping, six had midline lesions with successful mapping to one groin but failed mapping to the other groin, and one had unilateral mapping to the contralateral groin but not ipsilateral groin. The total successful sentinel lymph node mapping rate in this cohort was 86.5% (243/281 total sentinel lymph node attempts). CONCLUSION In this cohort, the overall success rate of sentinel lymph node mapping and biopsy was 86.5%. The high rate of successful sentinel lymph node mapping supports the use of intraoperative radiotracer and blue dye injection by trained providers.

Abstract
Lymph node metastasis is an indicator of the invasiveness and aggressiveness of cancer. It is a vital prognostic factor in clinical staging of the disease and therapeutic decision-making. Patients with positive metastatic lymph nodes are likely to develop recurrent disease, distant metastasis, and succumb to death in the coming few years. Lymph node dissection and histological analysis are needed to detect whether regional lymph nodes have been infiltrated by cancer cells and determine the likely outcome of treatment and the patient's chances of survival. However, these procedures are invasive, and tissue biopsies are prone to sampling error. In recent years, advanced molecular imaging with novel imaging probes has provided new technologies that are contributing to comprehensive management of cancer, including non-invasive investigation of lymphatic drainage from tumors, identifying metastatic lymph nodes, and guiding surgeons to operate efficiently in patients with complex lesions. In this review, first, we outline the current status of different molecular imaging modalities applied for lymph node metastasis management. Second, we summarize the multi-functional imaging probes applied with the different imaging modalities as well as applications of cancer lymph node metastasis from preclinical studies to clinical translations. Third, we describe the limitations that must be considered in the field of molecular imaging for improved detection of lymph node metastasis. Finally, we propose future directions for molecular imaging technology that will allow more personalized treatment plans for patients with lymph node metastasis.

Abstract
INTRODUCTION The sentinel lymph node (SLN) procedure for vulva cancer is a safe alternative to a radical inguino-femoral lymphadenectomy (IFLN) for small unifocal tumours. SLN evaluation through biopsy and ultra-staging has helped gynaecological oncology surgeons improve operative morbidity with no cost to oncologic safety. Established techniques for groin SLN detection and excision in vulvar cancer use 99mTc-nanocolloid radiotracer and blue dye (BD) for identification of the SLN. Indocyanine green (ICG)-near infrared (ICG-NIR) techniques for SLN mapping have proven utility in other gynaecological cancer sites and is gaining interest as a technique for SLN mapping in vulvar cancer METHODS: Fifty consecutive patients with unifocal vulvar squamous cell cancers of <40 mm lateral diameter and with depth of invasion > 1 mm underwent SLN mapping and excision using a combination of 99mTc-nanocolloid, BD and ICG. SLN detection results were recorded on a per-patient and per-groin basis. The success rates SLN for detection by individual tracer substance or combinations of tracer were determined by presence of one or more tracer, detectable in the SLN specimen. RESULTS 92% of patients had a successful SLN procedure. The per-groin detection rate was 84%. All successfully mapped SLN were identified with the combination of ICG-NIR and 99mTc-nanocolloid compared to 69% with BD 99mTc-nanocolloid. Success rates for the SLN procedure were not dependent on prior excision of the primary lesion or operator experience. CONCLUSIONS Incorporation of ICG-NIR into standard SLN mapping protocols may allow for the abandonment of routine use of BD and its poor side effect profile.

Abstract
PURPOSE Resection of the tumor-draining lymph -node (TDLN) represents a standard method to identify metastasis for several malignancies. Interestingly, recent preclinical studies indicate that TDLN resection diminishes the efficacy of immune checkpoint inhibitor-based cancer immunotherapies. Thus, accurate preclinical identification of TDLNs is pivotal to uncovering the underlying immunological mechanisms. Therefore, we validated preclinically, and clinically available non-invasive in vivo imaging approaches for precise TDLN identification. PROCEDURES For visualization of the lymphatic drainage into the TDLNs by non-invasive in vivo optical imaging, we injected the optical imaging contrast agents Patent Blue V (582.7 g mol-1) and IRDye® 800CW polyethylene glycol (PEG; 25,000-60,000 g mol-1), subcutaneously (s.c.) in close proximity to MC38 adenocarcinomas at the right flank of experimental mice. For determination of the lymphatic drainage and the glucose metabolism in TDLNs by non-invasive in vivo PET/magnetic resonance imaging (PET/MRI), we injected the positron emission tomography (PET) tracer (2-deoxy-2[18F]fluoro-D-glucose (18F-FDG) [181.1 g mol-1]) in a similar manner. For ex vivo cross-correlation, we isolated TDLNs and contralateral nontumor-draining lymph nodes (NTDLNs) and performed optical imaging, biodistribution, and autoradiography analysis. RESULTS The clinically well-established Patent Blue V was superior for intraoperative macroscopic identification of the TDLNs compared with IRDye® 800CW PEG but was not sensitive enough for non-invasive in vivo detection by optical imaging. Ex vivo Patent Blue V biodistribution analysis clearly identified the right accessory axillary and the proper axillary lymph node (LN) as TDLNs, whereas ex vivo IRDye® 800CW PEG completely failed. In contrast, functional non-invasive in vivo 18F-FDG PET/MRI identified a significantly elevated uptake exclusively within the ipsilateral accessory axillary TDLN of experimental mice and was able to differentiate between the accessory axillary and the proper LN. Ex vivo biodistribution and autoradiography confirmed our in vivo 18F-FDG PET/MRI results. CONCLUSIONS When taken together, our results demonstrate the feasibility of 18F-FDG-PET/MRI as a valid method for non-invasive in vivo, intraoperative, and ex vivo identification of the lymphatic drainage and glucose metabolism within the TDLNs. In addition, using Patent Blue V provides additive value for the macroscopic localization of the lymphatic drainage both visually and by ex vivo optical imaging analysis. Thus, both methods are valuable, easy to implement, and cost-effective for preclinical identification of the TDLN.

Abstract
BACKGROUND Performing inguinofemoral sentinel lymph node biopsy for vulvar cancer following a previous vulvar excision, often referred to as 'scar injection', is debated. OBJECTIVE To assess the feasibility of sentinel lymph node biopsy following scar injection and the long-term outcomes in patients undergoing this procedure. METHODS We conducted a retrospective observational cohort study of patients with vulvar cancer. We assessed detection rates and outcomes in patients who underwent sentinel lymph node biopsy by scar injection and compared them with patients who had injection around a visible tumor and with patients who had an inguinofemoral lymphadenectomy following previous vulvar excision. Sentinel node detection rates are described per patient and per groin and are compared using Χ2 analysis. Cox regression analysis was used to assess the association of recurrence and survival with surgical technique and recognized pathological variables. RESULTS Data were analyzed for 173 groins in 97 patients. At least one sentinel lymph node was detected in 162 (94%) groins examined, and detection rate did not differ whether the groin was assessed following tumor injection (n=122, 94%) or scar injection (n=40, 93%; p=0.85). Patients in the scar-injection group had less frequent lymph node metastases (p<0.02), smaller tumors (p<0.001), and more superficial invasion (p<0.02). Median follow-up was 34.7 months (range 0-108). Scar injection was not independently associated with recurrence or death on multivariable analysis, and depth of invasion was the only independent predictor of disease recurrence (hazards ratio (HR)=1.14, p=0.03). Recurrence and survival were also comparable for patients who had a sentinel lymph node biopsy or inguinofemoral lymphadenectomy following previous vulvar excision (log rank p=0.30; p=0.67). CONCLUSIONS Sentinel lymph node biopsy by scar injection is feasible and demonstrates similar long-term outcomes in patients having scar or tumor injections, and in patients following previous tumor excision undergoing sentinel lymph node biopsy or lymphadenectomy.

Abstract
STUDY OBJECTIVE The aim of this study was to evaluate the performance of indocyanine green (ICG) compared to that of the gold standard 99mtechnetium (99mTc-nanocolloids) in detecting sentinel lymph nodes (SLN) in early vulvar cancer. MATERIAL AND METHODS A single-center retrospective cohort study comparing SLN detection by 99mTc-nanocolloids and ICG was performed in patients presenting early vulvar cancer (T1/2), with clinically negative nodes. All SLN showing a radioactive and/or fluorescent signal were resected. The primary endpoints were the sensitivity, positive predictive value (PPV) and false negative (FN) rate of ICG in detecting SLN compared to 99mTc-nanocolloids. RESULTS Thirty patients were included and 99 SLN were identified in 43 groins. Compared to 99mTc-nanocolloids, ICG had a sensitivity of 80.8% (95% CI [72.6; 88.6%]), a PPV of 96.2% (95% CI [91.8; 100%]) and a FN rate of 19.1% in detecting SLN. Seventeen (17.1%) infiltrated (positive) SLN were identified out of the 99 SLN detected. Compared to 99mTc-nanocolloids, ICG showed a sensitivity of 82.3% (95% CI [73.1; 91.5%]), a PPV of 100% and a FN rate of 17.6% (3/17) in detecting infiltrated SLN. CONCLUSION Despite its many advantages, ICG cannot be used as the sole tracer for the detection of SLN in early vulvar cancer and should be employed in conjunction with 99mTc-nanocolloids.

Abstract
OBJECTIVES Sentinel lymph node (SLN) biopsy is widely accepted in the surgical staging of early vulvar cancer, although the most accurate method for its identification is not yet defined. This meta-analysis aimed to determine the technique with the highest pooled detection rate (DR) for the identification of SLN and compare the average number of SLNs detected by planar lymphoscintigraphy (PL), single-photon emission computed tomography/computed tomography (SPECT/CT), blue dye and indocyanine green (ICG) fluorescence. METHODS The meta-analysis was conducted according to the PRISMA guideline. The search string was: "sentinel" and "vulv*", with date restriction from 1st January 2010 until Dec 31st, 2020. Three investigators selected studies based on: (1) a study cohort or a subset of a minimum of 10 patients with vulvar cancer undergoing either PL, SPECT/CT, blue-dye, or ICG fluorescence for the identification of SLN; (2) the possibility to extrapolate the DR or the average number of SLNs detected by a single technique (3) no evidence of other malignancies in the patient history. RESULTS A total of 30 studies were selected. In a per-patient and a per-groin analysis, the DR for SLN of PL was respectively 96.13% and 92.57%; for the blue dye was 90.44% and 66.21%; for the ICG, the DR was 91.90% and 94.80%. The pooled DR of SPECT/CT was not calculated, since only two studies were performed in this setting. At a patient-based analysis, no significant difference was documented among PL, blue dye, and ICG (p = 0.28). At a per-groin analysis, PL and ICG demonstrated a significantly higher DR compared to blue dye (p < 0.05). The average number of SLNs, on a per-patient analysis, was available only for PL and ICG with a median number of 2.61 and 1.78 lymph nodes detected, respectively, and no significant statistical difference. CONCLUSIONS This meta-analysis favors the use of ICG and PL alone and in combination over blue dye for the identification of the SLN in vulvar cancer. Future studies may investigate whether the combined approach allows the highest DR of SLN in patients with vulvar cancer.

Abstract
Background: In recent years, scientific research on the gut microbiota and their relationship with some diseases, including neurological ones, has notably increased. As a result of these investigations, the so-called gut-brain axis arises. Despite its influence on the evolution and development of cognitive impairment, the gut-brain axis is little defined and demonstrated. Objective: To provide the best scientific evidence available on the relationship between the gut microbiota and Alzheimer’s disease. Method: Systematic and narrative review of the information generated in the last 5 years in national and international databases, in English and Spanish. Results: Eight observational studies were selected, carried out in humans and, therefore, suitable for inclusion in this review. Conclusion: The results of these studies support the hypothesis that there is a relationship between the gut microbiota and cognitive disorders through the gut-brain axis. However, today, there is a substantial lack of human studies, especially clinical trials, which makes it difficult to formulate clinical recommendations on this topic.

Abstract
OBJECTIVE To assess the diagnostic accuracy of intraoperative pathologic examination of sentinel lymph nodes (SLNs) and patient outcomes in vulva cancer. METHODS This retrospective study included patients with unifocal, <4 cm, invasive vulvar squamous cell carcinoma and clinically negative groin nodes treated with SLN biopsy from January 2008-March 2020. Intraoperative SLN frozen section and final pathology were compared. If the SLN was negative, inguinal femoral lymphadenectomy (IFLD) was omitted. Recurrence location and groin recurrence free survival (RFS) were assessed. RESULTS The SLN cohort included 173 patients, with 258 groins. On frozen section, there were 36/258 positive and 222 negative groins. On final pathology, there were 39/258 positive: 31 macrometastases, 6 micrometastases, 2 isolated tumor cells (ITCs) and 219 negative groins. The sensitivity, specificity, PPV and NPV for intraoperative detection of metastatic disease, was 89.7% and 99.5%, 97.2% and 98.2%, respectively. There was 1 false positive and 4 false negative frozen section results where final pathology revealed 2 ITCs, 1 micrometastasis and 1 macrometastasis. Based on intraoperative results, thirty patients (17.3%) underwent immediate IFLD. Median follow up was 38.0 (1-137.8) months. The 3-year groin RFS was 91.6% (95% CI 86.2-97.4%) for negative SLNs and 64.6% (95% CI 46.5-89.7%) for positive SLNs on frozen section. Similarly, the 3-year groin RFS was 91.7% (95% CI 86.3-97.4%) for negative, 58.4% (95% CI 38.5-87.7%) for macrometastases and 100% for micrometastases/ITCs on final pathology. CONCLUSIONS Intraoperative assessment of SLNs is accurate to determine need for IFLD and does not compromise patient outcomes in vulvar cancer.

Abstract
Simple Summary This prospective study has demonstrated that if the inguinal nodes medial to the lateral border of the femoral artery and the femoral nodes are negative in patients with vulvar cancer, the chances of having a positive node lateral to the artery are less than 1 in 10,000. About one-third of groin nodes are situated lateral to the femoral artery, so leaving these nodes in situ if the medial nodes are negative should significantly decrease the incidence and severity of lower limb lymphedema, without compromising survival. Abstract Background: Lower limb lymphedema is a long-term complication of inguino-femoral lymphadenectomy and is related to the number of lymph nodes removed. Our hypothesis was that lymph nodes lateral to the femoral artery could be left in situ if the medial nodes were negative, thereby decreasing this risk. Methods: We included patients with vulvar cancer of any histological type, even if the cancer extended medially to involve the urethra, anus, or vagina. We excluded patients whose tumor extended (i) laterally onto the thigh, (ii) posteriorly onto the buttocks, or (iii) anteriorly onto the mons pubis. After resection, the inguinal nodes were divided into a medial and a lateral group, based on the lateral border of the femoral artery. Results: Between December 2010 and July 2018, 76 patients underwent some form of groin node dissection, and data were obtained from 112 groins. Approximately one-third of nodes were located lateral to the femoral artery. Positive groin nodes were found in 29 patients (38.2%). All patients with positive nodes had positive nodes medial to the femoral artery. Five patients (6.6%) had positive lateral inguinal nodes. The probability of having a positive lateral node given a negative medial node was estimated to be 0.00002. Conclusion: Provided the medial nodes are negative, medial inguino-femoral lymphadenectomy may suffice and should reduce lower limb lymphedema without compromising survival.

Abstract
Ten percent of all women have pigmented vulvar lesions. Fortunately, most of these are benign but 1% of all melanomas in women affect the vulva. While the mortality rate of cutaneous melanoma has dropped by 7% annually during the last 5 years, the prognosis of vulvar melanoma remains dismal: the 5-year overall survival rate is 47% compared with 92% for cutaneous melanoma. The current evidence suggests that this likely results from a combination of delayed diagnosis and different tumor biology, treatment strategies, and treatment response. Although many landmark trials on checkpoint inhibitors included mucosal and vulvar melanomas, the results were often not reported separately. Post-hoc analyses indicate overall response rates between 19 and 37% for checkpoint inhibitors. A recently published retrospective study on vulvar melanomas suggests an objective response in 33.3% with a similar safety profile to cutaneous melanoma. Tyrosine kinase inhibitors may be considered in recurrent disease if a c-KIT mutation is present.

Abstract
Lymph node metastasis both increases disease stage and alters adjuvant treatment plans in gynecologic cancers. Since a minority of the patients have nodal metastasis, many patients unnecessarily undergo complete lymphadenectomy and are exposed to the subsequent morbidities. Sentinel lymph node (SLN) mapping is an alternative for evaluation of lymph nodes with lesser side effects. Although it is yet an experimental approach in ovarian cancer, it has been incorporated into guidelines for endometrial, cervical and vulvar cancers. We aimed to summarize the current situation of SLN mapping in gynecologic cancers.

Abstract
Sebaceous carcinoma (SC) is a rare and aggressive cutaneous malignancy. It often occurs on the eyelid, where it is called periocular SC, while extraocular SC mainly occurs on the head and heck. Extraocular vulvar SC is extremely rare; only nine cases have been described in the literature, and the optimal treatment strategy is unknown. We herein report a case of vulvar SC that was successfully treated with local excision in combination with sentinel lymph node biopsy (SNB). A 66-year-old female presented with vulvar discomfort. An 8 mm ulcerated mass was palpable in her left labia minora. Skin biopsy suggested SC. Imaging showed no swelling of the pelvic and inguinal lymph nodes and no metastasis. Sentinel lymph node scintigraphy using technetium-99 m showed three sentinel lymph nodes. The patient underwent local excision with SNB; intraoperative frozen-section examination revealed no nodal metastasis, and no further inguinal lymphadenectomy was performed. The final diagnosis was SC of the vulva, FIGO stage IB (pT1bN0M0). At the 14-month follow-up, she remained asymptomatic and had no signs of recurrence. The scientific rationale for SNB in extraocular SC has not yet been established, although SNB can be considered for periocular SC. However, considering the insufficient data on the management of vulvar SC and the aggressive nature of both periocular and extraocular SCs, SNB can be a reasonable and useful method for avoiding inadequate treatment and reducing the complications caused by unnecessary inguinal lymphadenectomy.

Abstract
Gynecologic cancers, including cervical, primary peritoneal, ovarian, uterine/endometrial, vaginal and vulvar cancers and gestational trophoblastic disease, are characterized by abnormal cell proliferation in female reproductive cells. Due to the variable pathology of these cancers and the lack of appropriate screening tests in developing countries, cancer diagnosis can be reported in advanced stages in most women and this situation adversely affects prognosis and clinical outcomes of illness. For this reason, many researchers in the field of gynecological oncology have carried out many studies. The treatment of various gynecological problems, which cause physical, biological and psychosocial conditions such as fear, shame, blame and anger, has been important throughout the history. Treatment with herbs has become popular nowadays due to the serious side effects of the synthetic drugs used in treatment and the medical and economical problems caused by them. Many scientists have identified various active drug substances through in vivo and in vitro biological activity studies on medicinal plants from the past to the present. While the intrinsic complexity of natural product-based drug discoveries requires highly integrated interdisciplinary approaches, scientific and technological advances and research trends clearly show that natural products will be among the most important new drug sources in the future. In this review, an overview of the studies conducted for the discovery of multitargeted drug molecules in the rational treatment of gynecological cancers is presented.

Abstract
Die Aufarbeitung von Lymphonodektomiepräparaten gynäkologischer Malignome orientiert sich an den nationalen AWMF-Leitlinien und internationalen Empfehlungen. Die Definition von Mikrometastasen und isolierten Tumorzellen entspricht den Festlegungen der UICC(Union Internationale Contre le Cancer)/TNM(TNM-Klassifikation maligner Tumoren). Deren Nachweis soll im Befundbericht erwähnt werden sowie in die Tumorklassifikation einfließen. Alle übersandten Lymphknoten (LK) sollen untersucht werden mit vollständiger Einbettung aller LK bis 0,3 cm und Lamellierung aller größeren Lymphknoten parallel zu ihrer kurzen Achse in ca. 0,2 cm dicken Scheiben. Bestandteile des histologischen Befundberichtes sind: Zahl der befallenen LK im Verhältnis zur Zahl der entfernten/untersuchten LK entsprechend der Entnahmelokalisationen, metrische Ausdehnung der größten LK-Metastase, Fehlen/Nachweis einer extrakapsulären Ausbreitung. Zuschnitt und Einbettung von Sentinel-LK mit oder ohne Schnellschnittuntersuchung erfolgt in Analogie zu Nicht-Sentinel-LK mit Anfertigung von ca. 3 HE-gefärbten Stufenschnitten in einem Abstand von ca. 200 µm sowohl vom Gefrier- als auch Paraffinblock. Stellen sich die Sentinel-LK in der HE-Färbung negativ dar, soll ein immunhistochemisches Ultrastaging erfolgen.

Abstract
Background This study aimed to evaluate the clinical value of indocyanine green sentinel lymph node (SLN) mapping in patients with vulvar cancer. The conventional procedure of SLN mapping in vulvar cancer includes peritumoral injection of technetium-99m nanocolloid before surgery and intraoperative injection of a blue dye. However, these techniques harbor some limitations. Near-infrared fluorescence imaging with indocyanine green has gained popularity in SLN mapping in different types of cancer. Methods We analyzed retrospectively vulvar cancer patients at our institution between 2013 and 2020 undergoing indocyanine green SLN mapping by applying video telescope operating microscope system technology. Results 64 groins of 34 patients were analyzed. In 53 groins we used technetium-99m nanocolloid, in four patent blue, and in five both techniques, additionally to indocyanine green for SLN detection. In total, 120 SLNs were identified and removed. The SLN detection rate of indocyanine green was comparable to technetium-99m nanocolloid (p=.143) and higher than patent blue (p=.003). The best results were achieved using a combination of ICG and technetium-99m nanocolloid (detection rate of 96.9%). SLN detection rates of indocyanine green were significantly higher in patients with positive lymph nodes (p=.035) and lymphatic space invasion (p=.004) compared to technetium-99m nanocolloid. Conclusion Indocyanine green SLN mapping in vulvar cancer is feasible and safe, with reasonable detection rates. Due to its easy application and few side effects, it offers a sound alternative to the conventional SLN mapping techniques in vulvar cancer. In patients with lymph node metastasis, indocyanine green even outperformed technetium-99m nanocolloid in terms of detection rate.

Abstract
Background Since the introduction of sentinel node biopsy (SLNB) in unifocal vulvar cancer (diameter of < 4 cm) and unsuspicious groin lymph nodes, the morbidity rate of patients has significantly decreased globally. In contrast to SLNB, bilateral inguinofemoral lymphadenectomy (IFL) has been associated with increased risk of common morbidities. Current guidelines (NCCN, ESGO, RCOG, and German) recommend that in cases of unilaterally positive sentinel lymph node (SLN), bilateral IFL should be performed. However, two recent publications by Woelber et al. and Nica et al. contradict the current guideline, since a significant rate of positive non sentinel lymph nodes in IFL contralaterally was not observed [Woelber et al. 0% (p = 0/28) and Nica et al. 5.3% (p = 1/19)].
Methods A retrospective single-center analysis conducted in the University Hospital of Dusseldorf, evaluating vulvar cancer patients treated with SLNB from 2002 to 2018. Results 22.2% of women (n = 4/18) were found to have contralateral IFL groin metastasis after an initial diagnosis of unilateral SLN metastasis. The depth of tumor infiltrating cells correlated significantly and positively with the rate of incidence of groin metastasis (p = 0.0038). Conclusion Current guideline for bilateral IFL should remain as the standard management. Therefore, this depth may be taken into account as an indication for bilateral IFL. The management of VC and SLNB should be performed in a high volume center with an experienced team in marking SLN and performing the adequate surgical procedure. Well conducted counseling of the patients outlining advantages but also potential oncological risks of this technique especially concerning rate of groin recurrence is critical.

Abstract
BACKGROUND The management for patients with vulvar cancer after sentinel lymph-node biopsy (SLNB) remains controversial. The aim of this study was to investigate the long-term outcomes of individualized management after SLNB for early stage vulvar cancer. METHODS The medical records of patients with vulvar cancer treated by surgery involving SLNB between 2004 and 2019 were retrospectively reviewed. During this period, the inguinofemoral lymphadenectomy (IL) were performed with individualized strategy, while the postoperative intensity-modulated radiotherapy was planned with a consistent policy. RESULTS We identified 138 patients with at least one sentinel node detected, of whom 64 underwent further IL while 74 had SLNB only. Nodal metastases (pN+) were confirmed in 22 patients with IL and 16 without. Radiotherapy was scheduled with the dose of 60-70 Gy for all pN+ patients and finally completed in 15 with IL and 15 without. The median follow-up time was 56 months (6-156 months). Recurrence was observed in 24 patients, of whom 10 were pN- at primary treatment. The 3-year overall survival (OS) was 97.2, 95.2, 68.3, and 71.8%; 3-year disease-free survival (DFS) was 94.5, 91.4, 60.2, and 59.2%, respectively, for patients with pN- and IL, pN- and SLNB, pN+ and IL, and pN+ and SLNB. Neither OS nor DFS showed significant difference between SLNB and IL in pN- (P = 0.564 for OS, P = 0.423 for DFS), or pN + patients (P = 0.920 for OS, P = 0.862 for DFS). CONCLUSIONS With appropriate adjuvant radiotherapy, SLNB alone provided similar long-term survival compared with IL for both patients with and without sentinel node metastasis.

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

Abstract
Assessment of lymphatic metastasis is an essential component of solid tumour staging. Sentinel lymph node (SLN) biopsy is a minimally invasive procedure that allows regional lymph node involvement by tumour to be estimated by selectively examining the sentinel lymph node while minimising the morbidity of systematic lymph node dissection. Within the group of genital cancers, the diagnostic value of SLN biopsy is rated differently. For selected patients with early-stage vulvar cancer (unifocal primary tumour < 4 cm, clinically negative inguinal lymph nodes) the SLN technique is already an established procedure in the guidelines of the German Society for Gynaecology and Obstetrics (DGGG)/German Cancer Society (DKG) and the recommendations of the European Society of Gynaecological Oncology (ESGO). For cervical cancer, SLN biopsy has not yet been sufficiently standardised but can be considered for patients without risk factors with a primary tumour size < 2 cm. The SLN
is identified by combined use of radioactive
99m
technetium nanocolloid and patent blue. The use of indocyanine green offers an alternative for SLN identification with few side effects. Recent studies aim to increase the diagnostic reliability of intraoperative frozen section analysis as this continues to show limited sensitivity in both vulvar and cervical cancer. The rate of detection of micrometastases can be increased by additional ultrastaging, the prognostic significance of which for both diseases is still unclear. The prognostic value of SLN biopsy compared with systematic lymph node dissection is being investigated in current studies (GROINSS-V-II for vulvar cancer and SENTIX-, SENTICOL-3 for cervical cancer). For this review article, a guideline-based literature search was performed in the National Library of Medicine (PubMed/MEDLINE) database with a particular focus on recent cohort studies and conference contributions.

Abstract
OBJECTIVE The aim of this study was to assess the superiority of ICG-99mTc-nanocolloid for the intraoperative visual detection of sentinel lymph nodes (SLNs) in vulvar squamous cell carcinoma (VSCC) patients compared to standard SLN detection using 99mTc-nanocolloid with blue dye. METHODS In this multicenter, randomized controlled trial, VSCC patients underwent either the standard SLN procedure or with the hybrid tracer ICG-99mTc-nanocolloid. The primary endpoint was the percentage of fluorescent SLNs compared to blue SLNs. Secondary endpoints were successful SLN procedures, surgical outcomes and postoperative complications. RESULTS Forty-eight patients were randomized to the standard (n = 24) or fluorescence imaging group (n = 24) using ICG-99mTc-nanocolloid. The percentage of blue SLNs was 65.3% compared to 92.5% fluorescent SLNs (p < 0.001). A successful SLN procedure was obtained in 92.1% of the groins in the standard group and 97.2% of the groins in the fluorescence imaging group (p = 0.33). Groups did not differ in surgical outcome, although more short-term postoperative complications were documented in the standard group (p = 0.041). CONCLUSIONS Intraoperative visual detection of SLNs in patients with VSCC using ICG-99mTc-nanocolloid was superior compared to 99mTc-nanocolloid and blue dye. The rate of successful SLN procedures between both groups was not significantly different. Fluorescence imaging has potential to be used routinely in the SLN procedure in VSCC patients to facilitate the search by direct visualization.

Abstract
INTRODUCTION Vulvar and vaginal melanomas are rare cancers of the female genital tract and account for 1% to 3% of all melanomas diagnosed in women. Due to the rarity of the disease, few data are available on the clinical and pathologic features of these cancers. Furthermore, treatment options are generally based on extrapolations of the information available for the more common cutaneous counterparts. Surgery represents the mainstay of treatment for lower genital tract melanoma. Moreover, the role of sentinel lymph node (SLN) assessment is controversial because no prospective data are available. EVIDENCE ACQUISITION Data were collected from Medline, Embase, Web of Sciences and Scopus databases. On July 10, 2020, we used the search comprising the terms "vulvar melanoma," "genital melanoma" and "vulvovaginal melanoma" including only studies in which SLN biopsy was performed. EVIDENCE SYNTHESIS Ten retrospective studies have been found. No randomized trials have been reported. The studies included 132 patients while only 63 (47%) undergone SLN. 99mTC with or without blue dye followed by ultrastaging was highly accurate and is currently the gold standard. Mean detection rate was 98.3%. No clear evidence supported the execution of back lymphadenectomy (after SLN mapping), in fact, extrapolating data from cutaneous melanomas of other sites, completion of lymphadenectomy does not confer a melanoma-specific survival advantage. CONCLUSIONS Although the small amount of available data, sentinel lymph node procedure is feasible and capable of identifying patients who have occult lymph node metastases. However, the potential role of the sentinel lymph node procedure as an alternative method of lymph node staging in patients with vulvar or vaginal melanoma needs further investigation.

Abstract
OBJECTIVES Superparamagnetic techniques for sentinel lymph node (SLNs) biopsy in breast cancer is well recognized but remains novel in the literature in relation to early stage vulvar cancer. The aim of this study was to compare and validate SLN detection using a superparamagnetic iron oxide tracer and a magnetometer probe compared with the standard procedure with a radioisotope (99Tc-technetium 99) and a gamma probe, in patients with vulvar cancer. METHODS Patients were included in the study with squamous vulvar tumors less than 4 cm in diameter and without suspicious groin lymph nodes on preoperative magnetic resonance imaging. Patients must have previously qualified for SLN biopsy with a radiotracer as the standard of care. The primary endpoint was the proportion of successful SLN detection with superparamagnetic iron oxide tracer versus 99Tc. The secondary endpoints were average number of SLNs retrieved per patient, proportion of SLNs detected (nodal detection rate), and proportion of pathologically positive results (malignancy rate) per patient and per node comparing both SLN detection methods. RESULTS A total of 20 patients were included in the study. SLNs were found in all patients with both methods, resulting in similar average distributions (3.1/3.2 SLN per patient). The SLN detection rate per patient was 100% with both techniques. Nodal detection sensitivity was 98.5% for the superparamagnetic technique and 93.8% for the radiotracer. Percentage of metastatic lymph nodes detected was 100% with both tracers. The rate of lymph node positivity was 21.5% (14 lymph nodes with metastases) and for patients 45% (9 patients with nodal metastases). Additionally, SLN tainted brown due to superparamagnetic iron oxide nanoparticles in 19 of 20 patients. CONCLUSIONS The use of superparamagnetic iron oxide tracer in patients with vulvar cancer seems reliable and not inferior to the standard approach with radiotracer.

Abstract
OBJECTIVES To characterize our institutional experience with sentinel lymph node (SLN) biopsy in patients with vulvar cancer. We describe the oncologic outcomes of these patients and the utilization of SLN detection techniques over time. METHODS A retrospective analysis of all patients who underwent inguinofemoral SLN biopsy as part of their treatment for vulvar cancer at Memorial Sloan Kettering Cancer Center from January 1, 2000 to April 1, 2019. Patients were included in this analysis if they underwent inguinofemoral SLN biopsy for vulvar cancer, irrespective of presenting factors such as histology, tumor size or laterality. An "at-risk groin" was defined as either the right or left groin for which SLN biopsy of inguinofemoral lymph nodes was performed. RESULTS A total of 160 patients were included in our analysis, representing 265 at-risk groins. 114 patients had squamous cell histology representing 195 at-risk groins. Of the 169 negative groins in patients with squamous cell carcinoma, the 2 year isolated groin recurrence rate was 1.2%. SLN detection rate, irrespective of modality, was 96.2%. Technetium-99 (TC-99) + blue dye detected SLNs in 91.8% of groins; TC-99 + indocyanine green detected SLNs in 100% of groins (p=0.157). Among the 110 groins that underwent mapping with TC-99 and blue dye, 4 patients had failed mapping with blue dye and mapped with TC-99 alone (3.6%). Among the 96 groins that underwent mapping with TC-99 and ICG, 14 patients failed to map with TC-99 and mapped with indocyanine green alone (14.6%). CONCLUSIONS SLN mapping in vulvar cancer is reliable and oncologically effective. The utilization of indocyanine green for mapping has increased over the past decade and is associated with high rates of SLN detection.

Abstract
PURPOSE Application of radioactive tracers for sentinel lymph node biopsy (SLNB) in vulvar cancer has been established, however, the use of radioisotopes is expensive and requires complex logistics. This exploratory study evaluated the feasibility of near-infrared fluorescence-based SLNB in comparison to the gold standard using radioactive guidance. METHODS At Evangelische Kliniken Essen-Mitte (Essen, Germany) between 02/2015 and 04/2019, 33 patients with squamous cell vulvar cancer and unifocal tumors (32 midline, 1 lateral) smaller than 4 cm underwent SLNB as part of their routine primary surgical therapy. Radiolabeled nanocolloid technetium 99 (99mTc) was injected preoperatively and indocyanine green (ICG) intraoperatively. Demographic and clinical data were retrieved from patients' records, and descriptive statistics were applied. The detection rate of the ICG fluorescence technique was compared with the standard radioactive approach. RESULTS In patients with midline tumors, bilateral SLNB was attempted. SLNB was feasible in 61/64 (95.3%) groins with 99mTc and in 56/64 (87.5%) with ICG. In total, 125 SLNs were excised; all SLNs were radioactive and 117 (93.6%) also fluorescent. In 8 patients with BMI > 30 kg/m2, SLNB was successful in 14/15 groins (93.3%) with 99mTc and 13/15 groins (86.7%) with ICG. Upon final histology, infiltrated nodes were present in 9/64 (14.1%) groins and 10/125 SLNs; one positive SLN was not detected with ICG. CONCLUSIONS SLNB using ICG is a promising technique, however, the detection rate obtained was slightly lower than with 99mTc. The detection rate increased over time indicating that experience and training may play an important role besides further methodological refinements.

Abstract
PURPOSE This study aimed to update the clinical practice applications and technical procedures of sentinel lymph node (SLN) biopsy in vulvar cancer from European experts. METHODS A systematic data search using PubMed/MEDLINE database was performed up to May 29, 2019. Only original studies focused on SLN biopsy in vulvar cancer, published in the English language and with a minimum of nine patients were selected. RESULTS Among 280 citations, 65 studies fulfilled the inclusion criteria. On the basis of the published evidences and consensus of European experts, this study provides an updated overview on clinical applications and technical procedures of SLN biopsy in vulvar cancer. CONCLUSIONS SLN biopsy is nowadays the standard treatment for well-selected women with clinically negative lymph nodes. Negative SLN is associated with a low groin recurrence rate and a good 5-year disease-specific survival rate. SLN biopsy is the most cost-effective approach than lymphadenectomy in early-stage vulvar cancer. However, future trials should focus on the safe extension of the indication of SLN biopsy in vulvar cancer. Although radiotracers and optical agents are widely used in the clinical routine, there is an increasing interest for hybrid tracers like indocyanine-99mTc-nanocolloid. Finally, it is essential to standardise the acquisition protocol including SPECT/CT images, and due to the low incidence of this type of malignancy to centralise this procedure in experienced centres for personalised approach.

Abstract
OBJECTIVE To evaluate the feasibility of fusion of ultrasound imaging and three-dimensional (3D) single-photon-emission computed tomography/computed tomography (SPECT/CT) in detecting sentinel lymph nodes in women with vulvar cancer. METHODS This was a prospective pilot single-center study. Patients with vulvar cancer who were candidates for sentinel lymph-node biopsy were enrolled between December 2018 and February 2019. Fusion imaging virtual navigation using 3D SPECT/CT and ultrasound was performed to investigate the tumor-draining lymph node. All clinical, imaging, surgical and histological information was collected prospectively and entered into a dedicated Excel file. Feasibility and success of fusion imaging virtual navigation and time needed to perform the three steps of fusion imaging were evaluated. RESULTS Ten lymph-node sites were evaluated in five consecutive women with a histological diagnosis of vulvar cancer. Fusion imaging virtual navigation was feasible and completed successfully for all (10/10) draining sites. Median overall time to perform fusion imaging was 32 (range, 25-40) min and the time decreased from the first to the last examination. CONCLUSIONS The present study demonstrated that fusion imaging virtual navigation using 3D SPECT/CT and ultrasound is feasible and able to detect sentinel lymph nodes in women with vulvar carcinoma. Fusion imaging using ultrasound for detection of sentinel lymph nodes opens up multiple diagnostic and therapeutic opportunities in gynecological oncology. Copyright © 2019 ISUOG.

Abstract
INTRODUCTION The aim of this study was to compare oncological outcomes and morbidity in patients with early-stage vulvar cancer with negative sentinel lymph node (SLN) biopsy vs negative inguinofemoral lymphadenectomy (IFL). MATERIAL AND METHODS Study with retrospectively collected data in patients with squamous cell vulvar carcinomas ≤ 4 cm without suspected inguinofemoral lymph node metastases. Only patients with negative nodes after histopathology procedure were followed. Patients who underwent only SLN were compared with patients who underwent IFL ± SLN to compare recurrences, survival rates and morbidity. RESULTS Ninety-three patients were eligible for follow up: 42 with negative SLN and 51 with negative IFL ± SLN. The median follow-up period was 60.4 months (range 6.7-160.7). The rate of isolated first groin recurrence was 4.8% in patients with negative SLN and 2.0% in patients with negative IFL ± SLN (P = 0.587) and the rates of first isolated local recurrence were 28.6% and 31.4%, respectively (P = 0.823). Only 1 patient (2.4%) in the group of negative SLN had distant recurrence. The disease-specific survival rate at 5 years was 83.3% in the negative SLN group and 92.2% in the negative IFL ± SLN group (P = 0.214). We observed a higher rate of wound breakdown and infection after IFL than SLN biopsy (17.6% vs 10.6%; P = 0.020) and lymphedema (33.3% vs 0%; P < 0.001). CONCLUSIONS We report in the same population of patients with early-stage vulvar cancer that SLN biopsy does not have significantly higher rates of groin recurrences or lower survival rates compared with IFL. Moreover, the SLN procedure has less morbidity, which should encourage gynecologists to abandon IFL.

Abstract
OBJECTIVE Sentinel node biopsy (SNB) has become standard of care in early stage vulvar cancer. As the correlation of isotope count with the presence of metastases remains unclear, often several active nodes are excised per groin. This can result in increased morbidity in node-negative disease despite of SNB. In the current analysis, we assess whether resection of the hottest node could be sufficient to detect sentinel lymph node (SLN) metastasis. METHODS Patients with primary vulvar cancer receiving an SNB with radioactive tracer at the University Medical Center Hamburg-Eppendorf between 2008 and 2015 were evaluated. RESULTS A total of 145 patients with SNB were analyzed; thereof, 144 underwent bilateral SNB, resulting in 289 analyzed groins. A median of 2 SLNs (range, 1-7) per groin were removed. From 94 (32.5%) of 289 groins, more than 2 SLNs were excised. Median overall SLN isotope count was 1400 cps. In 50 groins, a positive SLN was detected (unilateral in 38 patients, bilateral in 6). The median number of positive SLN per groin was 1 (range, 1-4). The SLN with the highest isotope count carried metastases in 36 (78.3%) of 46 groins (in 4 cases, the highest count was unknown). In 10 (21.7%) of 46 positive groins, the SLN with the highest count was not the metastatic SLN (9/10 second highest count). Median count of these 10 SLN was 60% of the highest count with a range from 11.0% to 74.0%. CONCLUSIONS The highest isotope count does not reliably detect the positive SLN in vulvar cancer. To prevent mostly fatal groin recurrences, surgeons should continue to remove all SLN accumulating relevant radioactive tracer over background activity.

Abstract
OBJECTIVE This study aims to compare the complications, oncological outcomes, cosmetic satisfaction, and quality of life experienced by women with vulvar cancer undergoing video endoscopic inguinal lymphadenectomy (VEIL) versus conventional open inguinal lymphadenectomy (COIL). PATIENTS AND METHODS Forty-eight consecutive patients with vulvar cancer who underwent COIL (n = 27) or VEIL (n = 21) at the Obstetrics and Gynecology Hospital of Fudan University, Shanghai, China between 2003 and 2016 were included in this retrospective cohort study. The perioperative data, postoperative complications, oncological outcomes, cosmetic satisfaction, and quality of life of the COIL and VEIL groups were compared. RESULTS Twenty patients (74.1%) in the COIL group and 19 patients (90.5%) in the VEIL group returned for follow-up after the operation. The median follow-up time was 73 months (8-162 months) for the COIL group and 28 months (8-58 months) for the VEIL group. The inguinal lymph node yield in the VEIL group was comparable with that in the COIL group (15 ± 5 vs 18 ± 6, P = 0.058). The VEIL and COIL groups had a similar 2-year recurrence rate (10.5% vs 10%, P = 0.957) and 2-year disease-specific survival rate (95.5% vs 93.3%, P = 0.724). The wound complication rate was significantly lower in the VEIL group than the COIL group (4.8% vs 55.6%, P = 0.000). The VEIL group had higher body image scores (16.27 ± 1.20 vs 13.16 ± 0.87, P < 0.0001) and cosmetic scores (20.13 ± 0.98 vs 16.92 ± 0.72, P < 0.0001) than the COIL group. The patients in the VEIL group had higher life quality scores on the Functional Assessment of Cancer Therapy-Vulvar questionnaire than those in the COIL group (165.9 ± 6.3 vs 160.5 ± 6.0, P = 0.026). CONCLUSIONS Compared with COIL, VEIL can effectively reduce postoperative wound complications and improve patients' cosmetic satisfaction and life quality without compromising therapeutic efficacy. Hence, we believe that VEIL is a good alternative to COIL for vulvar cancer patients when surgical expertise is available.

Abstract
OBJECTIVE To examine the use and predictors of sentinel node biopsy in women with vulvar cancer. METHODS The Perspective database, an all-payer database that collects data from more than 500 hospitals, was used to perform a retrospective cohort study of women with vulvar cancer who underwent vulvectomy and lymph node assessment from 2006 to 2015. Multivariable models were used to determine factors associated with sentinel node biopsy. Length of stay and cost were compared between women who underwent sentinel node biopsy and lymphadenectomy. RESULTS Among 2,273 women, sentinel node biopsy was utilized in 618 (27.2%) and 1,655 (72.8%) underwent inguinofemoral lymphadenectomy. Performance of sentinel node biopsy increased from 17.0% (95% confidence interval [CI] 12.0-22.0%) in 2006 to 39.1% (95% CI 27.1-51.0%) in 2015. In a multivariable model, women treated more recently were more likely to have undergone sentinel node biopsy, whereas women with more comorbidities and those treated at rural hospitals were less likely to have undergone the procedure. The median length of stay was shorter for those undergoing sentinel node biopsy (median 2 days, interquartile range 1-3) compared with women who underwent inguinofemoral lymphadenectomy (median 3 days, interquartile range 2-4). The cost of sentinel node biopsy was $7,599 (interquartile range $5,739-9,922) compared with $8,095 (interquartile range $5,917-11,281) for lymphadenectomy. CONCLUSION The use of sentinel node biopsy for vulvar cancer has more than doubled since 2006. Sentinel lymph node biopsy is associated with a shorter hospital stay and decreased cost compared with inguinofemoral lymphadenectomy.

Abstract
OBJECTIVE To identify suitable diagnostic tools and evaluate the efficacy of sentinel lymph node (SLN) biopsy for inguinal lymph node metastasis in vulvar cancer. METHODS Data from 41 patients with vulvar cancer were evaluated retrospectively, including magnetic resonance imaging (MRI) measurements, SLN biopsy status, groin lymph node metastasis, and prognosis. RESULTS SLN biopsy was conducted in 12 patients who had stage I to III disease. Groin lymphadenectomy was omitted in five of the nine patients with negative SLNs. All SLN-negative patients who did not undergo groin lymphadenectomy showed no evidence of disease after treatment. On MRI, the long and short diameters of the inguinal node were significantly longer in metastasis-positive cases, compared with negative cases, in 25 patients whose nodes were evaluated pathologically (long diameter, 12.8 mm vs. 8.8 mm, p=0.025; short diameter, 9.2 mm vs. 6.7 mm, p=0.041). The threshold of >10.0 mm for the long axis gave a sensitivity, specificity, positive predictive value, and negative predictive value of 87.5%, 70.6%, 58.3%, and 92.3%, respectively, using a binary classification test. Decision tree analysis revealed a sensitivity, specificity, and accuracy of 87.5%, 70.6%, and 76.0%, respectively, with the threshold of >10.0 mm for the long axis on MRI. The criteria of >10.0 mm for the long axis on MRI predicted an advanced stage and poorer prognosis using a validation set of 15 cases (p=0.028). CONCLUSION Minimally invasive surgery after preoperative evaluation on MRI and SLN biopsy is a feasible strategy for patients with vulvar cancer.

Abstract
BACKGROUND Sentinel Lymph Node (SLN) sampling may significantly reduce surgical morbidity by avoiding needless radical lymphadenectomy. In gynaecological cancers, the current practice in the UK is testing the accuracy of SLN detection using radioactive isotopes within the context of clinical trials. However, radioactive tracers pose significant logistic problems. We, therefore, conducted a pilot, observational study to assess the feasibility of a novel optical imaging device for SLN detection in gynaecological cancers using near infrared (NIR) fluorescence. METHODS A novel, custom-made, optical imaging system was developed to enable detection of multiple fluorescence dyes and allow simultaneous bright-field imaging during open surgery and laparoscopic procedures. We then evaluated the performance of the system in a prospective study of 49 women with early stage vulval, cervical and endometrial cancer who were scheduled to undergo complete lymphadenectomy. Clinically approved fluorescent contrast agents indocyanine green (ICG) and methylene blue (MB) were used. The main outcomes of the study included SLN mapping detection rates, false negative rates using the NIR fluorescence technique and safety of the procedures. We also examined the association between injection sites and differential lymphatic drainage in women with endometrial cancer by fluorescence imaging of ICG and MB. RESULTS A total of 64 SLNs were detected during both open surgery and laparoscopy. Following dose optimisation and the learning phase, SLN detection rate approached 100 % for all cancer types with no false negatives detected. Fluorescence from ICG and MB detected para-aortic SLNs in women with endometrial cancer following uterine injection. Percutaneous SLN detection was also achieved in most women with vulval cancer. No adverse reactions associated with the use of either dyes were observed. CONCLUSIONS This study demonstrated the successful clinical application of a novel NIR fluorescence imaging system for SLN detection across different gynaecological cancers. We showcased the first in human imaging, during the same procedure, of two fluorescence dyes in women with endometrial cancer.

Abstract
PURPOSE To determine the lymphatic drainage pattern using SPECT/CT in clinically node-negative (cN0) patients with vulvar cancer, and to evaluate the possible implications for the extent of inguinal lymph node dissection. METHODS A total of 83 patients with vulvar cancer scheduled for sentinel node (SN) biopsy were injected peritumorally with radioactive nanocolloid particles followed by lymphoscintigraphy and SPECT/CT for anatomical localization. The SN and higher-echelon nodes on SPECT/CT were located in different zones in the groin and pelvic region. The groin was divided into five zones according to Daseler et al.: four zones obtained by drawing two perpendicular lines over the saphenofemoral junction and one zone directly overlying this junction. The nodes in the pelvic region were classified into three zones: external iliac/obturator, the common iliac and the paraaortic zones. RESULTS A total of 217 SNs and 202 higher-echelon nodes were localized on SPECT/CT. All SNs were located in the five zones according to Daseler et al.: 149 (69%) in the medial superior region, 31 (14%) in the medial inferior region, 22 (10%) in the central region, 14 (6.5%) in the lateral superior region and only 1 (0.5%) in the lateral inferior region. The higher-echelon nodes were located both in the groin (15%) and in the pelvic region (85%). CONCLUSION In patients with cN0 vulvar cancer, lymphatic drainage occurs predominantly to the medial regions of the groin. Drainage to the lateral inferior region of the groin is only incidental and in SN-positive patients this zone might be spared in subsequent extended lymph node dissection. This may lead to a decrease in the morbidity associated with this procedure. SPECT/CT is able to personalize lymphatic mapping, providing detailed information about the number and anatomical location of SNs for adequate surgical planning in the groin.

Abstract
Near-infrared (NIR) fluorescence imaging has emerged as a promising complimentary technique for intraoperative visualization of tumor tissue, lymph nodes and vital structures. In this review, the current applications and future opportunities of NIR fluorescence imaging in gynecologic oncology are summarized. Several studies indicate that intraoperative sentinel lymph node identification in vulvar cancer using NIR fluorescence imaging outperforms blue dye staining and provides real-time intraoperative imaging of sentinel lymph nodes. NIR fluorescence imaging can penetrate through several millimeters of tissue, revealing structures just below the tissue surface. Hereby, iatrogenic damage to vital structures, such as the ureter or nerves may be avoided by identification using NIR fluorescence imaging. Tumor-targeted probes are currently being developed and have the potential to improve surgical outcomes of cytoreductive and staging procedures, in particular in ovarian cancer. Research in the near future will be necessary to determine whether this technology has additional value in order to facilitate the surgical procedure, reduce morbidity and improve disease-free and overall survival.
