Abstract
Vulval cancer is a rare gynaecological cancer, accounting for 3% of all gynaecological malignancies, with 47,000 cases in 2022 globally. Various imaging modalities are widely used in conjunction with clinical assessment in the diagnosis and staging of vulval cancers; however, there is significant heterogeneity in which modalities are recommended in international guidelines, reflecting the paucity of evidence in this area. We reviewed the current evidence for the role of imaging in vulval cancer. A systematic search of the literature was performed on the PubMed database using the MeSH terms 'vulval neoplasm' and 'diagnostic imaging'. We found that there is insufficient evidence to support the routine use of imaging for primary vulval tumours. For nodal assessment, there is no ideal imaging modality with sensitivity or specificity that is superior to other modalities. For distant metastases, CT CAP and FDG-PET/CT have the most evidence to support their use. In conclusion, the evidence for role of imaging in vulval cancer is limited by the heterogeneity of the study design and diagnostic criteria used in each study and the small sample size and retrospective nature of most studies.

Abstract
In recent years the role of diagnostic imaging by pelvic ultrasound in the diagnosis and staging of gynecological cancers has been growing exponentially. Evidence from recent prospective multicenter studies has demonstrated high accuracy for pre-operative locoregional ultrasound staging in gynecological cancers. Therefore, in many leading gynecologic oncology units, ultrasound is implemented next to pelvic MRI as the first-line imaging modality for gynecological cancer. The work herein is a consensus statement on the role of pre-operative imaging by ultrasound and other imaging modalities in gynecological cancer, following European Society guidelines.

Abstract
The safety and utility of endotracheal intubation by paramedics in the United Kingdom is a matter of debate. Considering the controversy surrounding the safety of paramedic-performed endotracheal intubation, any interventions that enhance patient safety should be evaluated for implementation based on solid evidence of their effectiveness. A systematic review performed by Hansel and colleagues (2022) sought to assess compare video laryngoscopes against direct laryngoscopes in clinical practice. This commentary aims to critically appraise the methods used within the review by Hansel et al (2022) and expand upon the findings in the context of clinical practice.

The Role of Ultrasound in the Evaluation of Inguinal Lymph Nodes in Patients with Vulvar Cancer: A Systematic Review and Meta-Analysis. Cancers (Basel) 2022; 14:cancers14133082. [PMID: 35804853 PMCID: PMC9265034 DOI: 10.3390/cancers14133082] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/21/2022] [Revised: 06/19/2022] [Accepted: 06/19/2022] [Indexed: 02/06/2023] Open
Abstract
Simple Summary Currently, around 30% of vulvar cancer cases at first diagnosis are spread to the inguinal lymph nodes. Preoperative staging of patients affected by vulvar carcinoma is still a hot topic. To date, MRI has shown a great diagnostic accuracy on defining disease extension to soft tissue and deep organs. At present, regarding the study of inguinal nodes, the PET/CT scan has shown a high negative predictive value, although in the presence of a suspicious/positive report it should be taken with caution. We report the results of a study aimed to investigate the role of groin ultrasound in the assessment of lymph nodal status in vulvar cancer. Furthermore, this review represents the most accurate collection of papers available in the literature. This work demonstrates that groin ultrasound can be considered a valuable tool for risk assessment of the presence of groin lymph node metastases. Achieving a high diagnostic accuracy would allow tailored surgical planning with access to minimally invasive surgery techniques for an increasing number of patients. Abstract Objective. To determine the efficacy of ultrasound in assessing the inguinal lymph nodes in patients with vulvar cancer. Methods. A systematic review of published research up to October 2020 that compares the results of ultrasound to determine groin node status with histology was conducted. All study types that reported primary data on the role of ultrasound in the evaluation of groin lymph nodes in vulvar cancer were included in the systematic review. Data retrieved from the included studies were pooled in random-effects meta-analyses. Results. After the screening and selection process, eight articles were deemed pertinent for inclusion in the systematic review and meta-analysis. The random-effects model showed a pooled Se of 0.85 (95% CI: 0.81–0.89), Sp of 0.86 (95% CI: 0.81–0.91), PPV of 0.65 (95% CI: 0.54–0.79) and NPV of 0.92 (95% CI: 0.91–0.94). There was a pooled LR+ and LR− of 6.44 (95% CI: 3.72–11.4) and 0.20 (95% CI: 0.14–0.27), respectively. The pooled accuracy was 0.85 (95% CI: 0.80–0.91). Conclusions. Although the studies had small sample sizes, this review represents the best summary of the data so far. Ultrasound has revealed high sensitivity and high negative predictive value in the assessment of nodal status in vulvar cancer.

Abstract
MR imaging provides excellent spatial and contrast resolution to stage locally advanced vulvar cancer (LAVC) for tumor and nodal evaluation in order to facilitate the planning of treatment. Although there are no standard indications for how to estimate the clinical stage of International Federation of Gynecology and Obstetrics at diagnosis, MR imaging can depict the tumor and its extension to the vulvar region and adjacent organs, such as the vagina, urethra, and anus. Optimizing the MR imaging protocol and technique is fundamental for correct staging. The aim of this overview was to focus on the role of MR imaging in LAVC staging. We define vulvar anatomy and corresponding MR imaging findings, MR imaging protocol, and technique. Moreover, we describe the MR imaging findings of LAVC with example cases stage by stage. Key imaging findings based on signal intensity, diffusion restriction, and enhancement are portrayed to correctly identify and stage vulvar cancer. A structured report for LAVC staging is reported in order to give all necessary information to the clinicians and to facilitate MR imaging comprehension.

Abstract
Objective The aim of the Female Pelvic Imaging Working Group of the European Society of Urogenital Radiology (ESUR) was to develop imaging staging guidelines for vulvar cancer and to propose standardised MRI protocols and reporting. Methods The guidelines recommended from the ESUR in this article resulted from a questionnaire analysis regarding imaging staging of vulvar cancer that was answered by all members of the Female Pelvic Imaging Working Group. Only the answers with an agreement equal to or more than 80% were considered. Additionally, the literature was reviewed to complement and further support our conclusions. Results The critical review of the literature and consensus obtained among experts allows for recommendations regarding imaging staging guidelines, patient preparation, MRI protocol, and a structured MRI report. Conclusions Standardising image acquisition techniques and MRI interpretation reduces ambiguity and ultimately improves the contribution of radiology to the staging and management of patients with vulvar cancer. Moreover, structured reporting assists with the communication of clinically relevant information to the referring physician.

Abstract
Vulvar cancer is an uncommon gynecologic tumor and one of several human papillomavirus-associated malignancies. Squamous cell carcinoma is the most prevalent histologic subtype of vulvar cancer, accounting for the majority of cases. Imaging plays an important role in managing vulvar cancer. At initial diagnosis, imaging is useful to assess the size and extent of primary tumor and to evaluate the status of inguinofemoral lymph nodes. If recurrent disease is suspected, imaging is essential to demonstrate local extent of tumor and to identify lymph node and distant metastases. In this publication, we summarize the recent literature and describe the panel's recommendations about the appropriate use of imaging for various phases of patient management including initial staging, surveillance, and restaging of vulvar cancer. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
Radiotherapy planning and delivery have dramatically improved in recent times. Imaging is key to a successful three-dimensional and increasingly four-dimensional based pathway with computed tomography embedded as the backbone modality. Computed tomography has significant limitations for many tumour sites where soft-tissue discrimination is suboptimal, and where magnetic resonance imaging (MRI) has largely superseded in the diagnostic arena. MRI is increasingly used together with computed tomography in the radiotherapy planning pathway and is now established as a prerequisite for several tumours. With the advent of combined MRI and linear accelerator (MR-linac) systems, a transition to MRI-based radiotherapy planning is becoming reality, with increasing experience and research involving these new platforms. In this overview, we aim to highlight how magnetic resonance-guided imaging has improved radiotherapy, using gynaecological malignancies to illustrate, in both external beam radiotherapy and image-guided brachytherapy, and will assess the early evidence for magnetic resonance-guided radiotherapy using combined MR-linac systems.

Abstract
INTRODUCTION Vulvar squamous cell carcinoma (VSCC) commonly metastasises through groin lymphatics. However, the use of pre-operative imaging in detecting inguinal nodal metastasis before staging surgery or to triage patients for sentinel node biopsy remains unclear. Here, we investigated if pre-operative CT scan, the imaging choice in our cancer centre, influences the overall course of VSCC management in those patients without clinical evidence of groin lymphadenopathy. METHOD The study comprised of a prospective cohort of 225 patients with VSCC who underwent staging surgery within a regional tertiary gynaecological cancer centre. Comprehensive information of the cohort's demography, clinicopathological variables and outcome data were collected and analysed. Findings of pre-operative imaging were compared with histological findings of inguinal lymph nodes following groin lymphadenectomy. Statistical analyses were performed using SPSS V24. RESULTS Pre-operative CT scan was performed on 116 (56.6%) patients. The sensitivity and specificity of cross-sectional imaging in detecting groin lymphatic metastasis were 59.1% and 77.8%, respectively; while the positive (PPV) and negative predictive value (NPV) were 61.9% and 75.7%, respectively. In patients who had sentinel inguinal nodes biopsy, the sensitivity, specificity, PPV and NPV of CT scan in detecting inguinal node metastasis were 30.0%, 85.7%, 33.3% and 83.7%, respectively. There was no difference in disease-free and overall survival in those who received pre-operative imaging when compared to those who did not. CONCLUSION Pre-operative CT scan may be omitted in early stage VSCC prior to surgical staging as it does not affect overall management and surgical outcomes.

Abstract
Vulvar carcinoma is an uncommon tumor that predominantly affects postmenopausal
women. Currently, there is no screening procedure for vulvar carcinoma; in most
cases, it is diagnosed only when symptoms appear. The most widely used staging
system is that developed by the International Federation of Gynecology and
Obstetrics. Lymph node status is the most important prognostic factor. We
searched the PubMed/Medline database to identify relevant English-language
articles on vulvar cancer, with a special focus on its imaging evaluation.
Magnetic resonance imaging is useful for local and nodal staging, as well as
facilitating the planning of surgical interventions and radiotherapy. Computed
tomography or positron-emission tomography/computed tomography can play an
important role in nodal and distant disease assessment, whereas ultrasound is
often used for image-guided biopsies. Imaging is pivotal for staging and
treatment planning in vulvar carcinoma.

Abstract
Locally advanced human papillomavirus (HPV)-associated gynecologic cancers, including cervical, vaginal, and vulvar cancers, are treated primarily with radiation therapy (RT). Cervical cancer remains a leading cause of cancer death among women worldwide. The superior soft-tissue resolution of MRI compared with other imaging modalities makes it an ideal modality for RT planning, execution, and follow-up of these malignancies. This superiority has been corroborated in the literature when comparing MRI-based RT planning to radiography-based conventional treatment planning approaches. In 2005, the Groupe Européen de Curiethérapie and the European Society for Radiation Therapy and Oncology guidelines underscored the central role of MRI for successful implementation of three-dimensional image-based cervical cancer brachytherapy. The delineation of both gross tumor volume and clinical tumor volume for brachytherapy is performed at the time of each brachytherapy application, on the basis of the findings depicted on anatomic MR images. Contemporary knowledge concerning the role of MRI for RT planning in HPV-associated gynecologic cancers warrants an understanding of the epidemiology and clinical manifestations of these cancers, as well as knowledge of MRI protocol for cancer staging, selection of RT candidates, brachytherapy implant assessment, posttreatment surveillance, and delineation of treatment-related complications. Technical requirements, patient preparation, and image acquisition protocols are detailed in this review, and imaging-based treatment protocols are summarized. Knowledge of these fundamental concepts enables the radiologist to play an important role in diagnosis, staging, and posttreatment follow-up, helping to guide radiation oncologists and other clinicians in the management of these malignancies.©RSNA, 2019.

Abstract
Purpose: This is an official guideline, published and coordinated by the Arbeitsgemeinschaft Gynäkologische Onkologie (AGO, Study Group for Gynecologic Oncology) of the Deutsche Krebsgesellschaft (DKG, German Cancer Society) and the Deutsche Gesellschaft für Gynäkologie und Geburtshilfe (DGGG, German Society for Gynecology and Obstetrics). The number of cases with vulvar cancer is on the rise, but because of the former rarity of this condition and the resulting lack of literature with a high level of evidence, in many areas knowledge of the optimal clinical management still lags behind what would be required. This updated guideline aims to disseminate the most recent recommendations, which are much clearer and more individualized, and is intended to create a basis for the assessment and improvement of quality care in hospitals. Methods: This S2k guideline was drafted by members of the AGO Committee on Vulvar and Vaginal Tumors; it was developed and formally completed in accordance with the structured consensus process of the Association of Scientific Medical Societies in Germany (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften, AWMF). Recommendations: 1. The incidence of disease must be taken into consideration. 2. The diagnostic pathway, which is determined by the initial findings, must be followed. 3. The clinical and therapeutic management of vulvar cancer must be done on an individual basis and depends on the stage of disease. 4. The indications for sentinel lymph node biopsy must be evaluated very carefully. 5. Follow-up and treatment for recurrence must be adapted to the individual case.

Abstract
Subpubic cartilaginous cyst was recently reported as a rare degenerative mass on the pubic symphysis. We report here a 59-year-old woman who presented with a vulvar mass that showed complete spontaneous regression 48 months after the initial visit. Treatment was only wearing brace. This is the first report of complete spontaneous regression of a subpubic cartilaginous cyst. In the case of small subpubic cyst, observation and follow-up alone may be sufficient. J. Med. Invest. 63: 319-322, August, 2016.

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
EPIDEMIOLOGY Vulvar cancer can be classified into two groups according to predisposing factors: the first type correlates with a HPV infection and occurs mostly in younger patients. The second group is not HPV associated and occurs often in elderly women without neoplastic epithelial disorders. HISTOLOGY Squamous cell carcinoma (SCC) is the most common malignant tumor of the vulva (95%). CLINICAL FEATURES Pruritus is the most common and long-lasting reported symptom of vulvar cancer, followed by vulvar bleeding, discharge, dysuria, and pain. THERAPY The gold standard for even a small invasive carcinoma of the vulva was historically radical vulvectomy with removal of the tumor with a wide margin followed by an en bloc resection of the inguinal and often the pelvic lymph nodes. Currently, a more individualized and less radical treatment is suggested: a radical wide local excision is possible in the case of localized lesions (T1). A sentinel lymph node (SLN) biopsy may be performed to reduce wound complications and lymphedema. PROGNOSIS The survival of patients with vulvar cancer is good when convenient therapy is arranged quickly after initial diagnosis. Inguinal and/or femoral node involvement is the most significant prognostic factor for survival.

Abstract
BACKGROUND Vulval cancer is usually treated by wide local excision with removal of groin lymph nodes (inguinofemoral lymphadenectomy) from one or both sides, depending on the tumour location. However, this procedure is associated with significant morbidity. As lymph node metastasis occurs in about 30% of women with early vulval cancer, accurate prediction of lymph node metastases could reduce the extent of surgery in many women, thereby reducing morbidity. Sentinel node assessment is a diagnostic technique that uses traceable agents to identify the spread of cancer cells to the lymph nodes draining affected tissue. Once the sentinel nodes are identified, they are removed and submitted to histological examination. This technique has been found to be useful in diagnosing the nodal involvement of other types of tumours. Sentinel node assessment in vulval cancer has been evaluated with various tracing agents. It is unclear which tracing agent or combination of agents is most accurate. OBJECTIVES To assess the diagnostic test accuracy of various techniques using traceable agents for sentinel lymph node assessment to diagnose groin lymph node metastasis in women with FIGO stage IB or higher vulval cancer and to investigate sources of heterogeneity. SEARCH METHODS We searched MEDLINE (1946 to February 2013), EMBASE (1974 to March 2013) and the relevant Cochrane trial registers. SELECTION CRITERIA Studies that evaluated the diagnostic accuracy of traceable agents for sentinel node assessment (involving the identification of a sentinel node plus histological examination) compared with histological examination of removed groin lymph nodes following complete inguinofemoral lymphadenectomy (IFL) in women with vulval cancer, provided there were sufficient data for the construction of two-by-two tables. DATA COLLECTION AND ANALYSIS Two authors (TAL, AP) independently screened titles and abstracts for relevance, classified studies for inclusion/exclusion and extracted data. We assessed the methodological quality of studies using the QUADAS-2 tool. We used univariate meta-analytical methods to estimate pooled sensitivity estimates. MAIN RESULTS We included 34 studies evaluating 1614 women and approximately 2396 groins. The overall methodological quality of included studies was moderate. The studies included in this review used the following traceable techniques to identify sentinel nodes in their participants: blue dye only (three studies), technetium only (eight studies), blue dye plus technetium combined (combined tests; 13 studies) and various inconsistent combinations of these three techniques (mixed tests; 10 studies). For studies of mixed tests, we obtained separate test data where possible.Most studies used haematoxylin and eosin (H&E) stains for the histological examination. Additionally an immunohistochemical (IHC) stain with and without ultrastaging was employed by 14 and eight studies, respectively. One study used reverse transcriptase polymerase chain reaction analysis (CA9 RT-PCR), whilst three studies did not describe the histological methods used.The pooled sensitivity estimate for studies using blue dye only was 0.94 (68 women; 95% confidence interval (CI) 0.69 to 0.99), for mixed tests was 0.91 (679 women; 95% CI 0.71 to 0.98), for technetium only was 0.93 (149 women; 95% CI 0.89 to 0.96) and for combined tests was 0.95 (390 women; 95% CI 0.89 to 0.97). Negative predictive values (NPVs) for all index tests were > 95%. Most studies also reported sentinel node detection rates (the ability of the test to identify a sentinel node) of the index test. The mean detection rate for blue dye alone was 82%, compared with 95%, 96% and 98% for mixed tests, technetium only and combined tests, respectively. We estimated the clinical consequences of the various tests for 100 women undergoing the sentinel node procedure, assuming the prevalence of groin metastases to be 30%. For the combined or technetium only tests, one and two women with groin metastases might be 'missed', respectively (95% CI 1 to 3); and for mixed tests, three women with groin metastases might be 'missed' (95% CI 1 to 9). The wide CIs associated with the pooled sensitivity estimates for blue dye and mixed tests increased the potential for these tests to 'miss' women with groin metastases. AUTHORS' CONCLUSIONS There is little difference in diagnostic test accuracy between the technetium and combined tests. The combined test may reduce the number of women with 'missed' groin node metastases compared with technetium only. Blue dye alone may be associated with more 'missed' cases compared with tests using technetium. Sentinel node assessment with technetium-based tests will reduce the need for IFL by 70% in women with early vulval cancer. It is not yet clear how the survival of women with negative sentinel nodes compares to those undergoing standard surgery (IFL). A randomised controlled trial of sentinel node dissection and IFL has methodological and ethical issues, therefore more observational data on the survival of women with early vulval cancer are needed.

Abstract
OBJECTIVE The purpose of this article is to review the imaging features, particularly on MR images, useful in identifying primary gynecologic lymphoma. CONCLUSION Primary gynecologic lymphoma is rare. Nonetheless, the distinction between primary and secondary involvement is important because of critical differences in prognosis and treatment. The prospective diagnosis of primary gynecologic lymphoma enables immediate chemotherapy or radiation therapy and avoids unnecessary surgery, which delays treatment. Diagnostic imaging can be key in differentiating lymphoma from the far more common pelvic malignancies.

Abstract
PURPOSE To evaluate the detectability and credibility of sentinel lymph node (SLN) in vulvar cancer. METHODS With Tc99m-nanocolloid and methylene blue, we identified SLNs in 34 patients. In 27 cases both tracers were used, while in 7 only blue dye was used. Completion lymphadenectomy was performed in all patients. SLNs and non-SLNs were sent separately for pathologic evaluation. RESULTS At least one SLN was identified in all patients. Detection rate per groin was not significantly higher in the combined versus blue dye only technique (42/50 vs. 10/14, p = 0.43). 99m-Tc was not superior to blue dye in detecting SLN (42/50 vs. 50/64, p = 0.65). Midline location of the tumor did not seem to negatively affect the procedure. Four false negatives were observed in three patients with tumors >4 cm. Negative predictive value of SLN was 100% for grade I tumors ≤ 4 cm in patients ≤ 71 years. CONCLUSION Tc-99m does not seem to be superior to methylene blue in the detection of SLN in vulvar cancer. Patients of younger age with small, well-differentiated tumors appear to be the most suitable candidates for lymphatic mapping.

Abstract
The clinical problems raised in patients presenting with all forms of gynecological malignancy are currently addressed using conventional cross-sectional imaging, usually MRI. In general, F-18 FDG PET-CT has not been shown to have a clinical role in any of these cancers at presentation, although studies are under way to use this form of metabolic imaging to predict prognosis and the response to treatment. Although F-18 FDG PET-CT is superior to conventional imaging techniques, it is only moderately sensitive in demonstrating lymph node metastasis preoperatively, and is inadequate for local staging of patients with endometrial cancer. In ovarian cancer, F-18 FDG PET-CT provides an accurate assessment of the extent of disease, particularly in areas difficult to assess for metastases by CT and MRI such as the abdomen and pelvis, mediastinum, and supraclavicular region. F-18 FDG PET-CT is a sensitive method of detecting pelvic and para-aortic lymph nodal disease in cervical cancer, and appears to be superior to MRI and CT despite the limitations in identifying small foci of disease. In the main, as elsewhere in patients with cancer, the value of PET-CT is in identifying and defining the extent of recurrent disease, in distinguishing between posttreatment fibrosis and recurrence, and possibly in monitoring response to therapy.

Abstract
Magnetic resonance imaging (MRI) has become an indispensable tool in the assessment of malignant disease. With increasingly sophisticated systems and technical advancements, MRI has continued to expand its role in providing crucial information regarding cancer diagnosis and management. In gynecological malignancies, this modality has assumed greater responsibility, particularly in the evaluation of cervical and endometrial cancers. In addition to conventional imaging, innovative techniques such as dynamic contrast-enhanced MRI and diffusion-weighted MRI show promise in offering early assessment of tumor response. This paper reviews the current role of MRI in gynecological cancers and highlights the potential of novel techniques in improving patient care.

Abstract
We present a case of a postmenopausal female who visited her doctor for a slowly growing mass in the vulval region. The mass did not show typical clinical features of a vulval neoplasm. Magnetic resonance imaging (MRI) revealed a mass arising from the undersurface of the symphysis pubis. A literature review revealed characteristics of this lesion compatible with a subpubic cartilaginous cyst-a rare benign degenerative condition of the symphysis pubis. As a result the mass was managed non-operatively and the patient remains well 2 years later. This article highlights the role of MRI in the diagnosis of this unusual vulval mass.

Abstract
OBJECTIVE To investigate the diagnostic accuracy of the sentinel node procedure in patients with vulvar cancer, a multicenter study was launched in Germany in 2003 involving 7 oncology centers. PATIENTS AND METHODS Between 2003 and 2006, 127 women with primary T1-T3 vulvar cancer were entered in the study and treated with sentinel node removal after application of (99m)Technetium labeled nanocolloid and/or blue dye. Subsequently, in all women a complete inguinofemoral lymphadenectomy and the adequate vulvar operation were performed. Sentinel lymph nodes were examined by routine pathologic examination (H&E), followed by step-sectioning and immunhistochemistry if negative. RESULTS The sentinel node procedure was successful in 125 out of 127 cases, in 2 cases no sentinel nodes were detected. 21 patients received unilateral lymphadenectomy, 103 women were operated on both groins. In 39 women out of 127, positive lymph nodes in one or both groins were identified (30.7%). In 36 women, the sentinel nodes were also positive (sensitivity 92.3%). We had three cases with a false negative sentinel node (false negative rate: 7.7%), all of these women presenting with tumors in midline position. One tumor was a T1 tumor (10 mm), 2 tumors being classified as T2 (40 and 56 mm, respectively). In one additional case (18 mm T1 tumor, midline position), the sentinel was positive in the right groin, but false negative on the left side. CONCLUSIONS This study shows that identification of SLN in squamous cell cancer of the vulva is feasible, however not highly accurate depending on tumor localization and size. The false negative rate seems to be acceptable if the procedure is restricted to stage 1 tumors with clinically negative lymph node status. Tumors situated in or close to the midline seem to be less suitable for this procedure. Implementation of SLNB into clinical practice should be performed with care and only by experienced teams as to avoid preventable groin relapses.

Abstract
Poor perineal healing is often a major complication of extended radical vulvectomy in case of vulvar carcinoma. Procedures of vulvoperineal reconstruction require several criteria of quality for their use. The chosen technique should be: (1) reliable; (2) reproducible; (3) with minimal morbidity; (4) not much invasive with good anatomical and functional results. We describe two procedures of perineal reconstruction that correspond to the previous criteria: a local fasciocutaneous flap with lateral transposition and a regional musculocutaneous flap using the gluteus maximus muscle.

Abstract
MR imaging using anatomic, chemical, and functional information offers huge potential for the management of the gynecologic patient. By differentiating benign from malignant disease with very high specificity, it can aid the selection of patients requiring further treatment and determine the level of urgency. Staging accuracy, which equals that obtained at laparotomy, allows appropriate clinical expertise to be organized before surgery or the deferment of surgery until later in the treatment pathway and is a cost-effective use of resources. This article compares and contrasts MR imaging of gynecologic conditions at 1.5 and 3T and defines a role for high field imaging for these clinical conditions.

Abstract
OBJECTIVE To study the accuracy of magnetic resonance imaging (MRI) in lymph node detection in patients with vulva carcinoma. METHODS Sixty patients with diagnosed vulva carcinoma underwent MRI examination for preoperative evaluation of lymph nodes. MRI images were read independently and retrospectively by two radiologists, both unaware of physical examination and surgery findings. The following characteristics of each lymph node with a short-axis diameter of >or=8 mm were recorded: size (axial, sagittal and coronal); aspect (homogeneous, with fatty center or partial fat); margin (smooth, lobulated/speculated or indistinct); shape: (round, ovoid or elongated). Based on these characteristics, each lymph node was classified as malignant or benign and subsequently each groin was classified as malignant or benign. Histopathology obtained at sentinel node procedure or by inguinofemoral lymphadenectomy was used as reference standard. Per groin sensitivity, specificity, positive and negative predictive values were calculated. Kappa statistics on per groin basis were calculated to express interobserver agreement. RESULTS One hundred nineteen groins were examined either by sentinel node procedure or surgery, of which 23 groins were malignant. Sensitivity, specificity, positive and negative predictive values were 52%, 85%, 46% and 87% for observer 1 and 52% 89%, 52% and 89% for observer 2. The interobserver agreement was 104/119 (kappa 0.62), representing good agreement. CONCLUSION At this stage there is no role for standard MRI in evaluating lymph node involvement in patients with vulva carcinoma.

Abstract
The majority of patients with vulvar cancer have squamous cell carcinomas (SCC). The cornerstone of the treatment is surgery. Radical vulvectomy with "en bloc" inguinofemoral lymphadenectomy has led to a favorable prognosis but with impressive morbidity. Nowadays, treatment is more individualized with wide local excision with uni- or bilateral inguinofemoral lymphadenectomy via separate incisions as the standard treatment for early stage patients with SCC of the vulva with depth of invasion >1 mm without suspicious groins. In case of more than one intranodal lymph node metastasis and/or extranodal growth, postoperative radiotherapy on the groins and pelvis is warranted. Until now there is a limited role for primary radiotherapy on the vulva and/or groins in early stage disease. The sentinel lymph node (SLN) procedure with the combined technique (preoperative lymphoscintigraphy with a radioactive tracer and intraoperative blue dye) is a promising staging technique for patients with early stage vulvar cancer. The safety of clinical implementation of the SLN procedure and the role of additional histopathological techniques of the SLNs need to be further investigated before its wide-scale application. Patients with advanced vulvar cancer are difficult to treat. One of the problems in patients with locally advanced vulvar cancer is the high incidence of concomitant bulky lymph nodes in the groin(s). Ultraradical surgery in case of resectable disease will lead to impressive morbidity because of the exenterative-type procedure. (Chemo)radiation with or without surgery should be regarded as the first choice for patients with locally advanced vulvar cancer only when primary surgery will necessitate performance of a stoma. Further studies are needed to determine the optimal combined modality treatment in these patients. Due to the fact that vulvar cancer is a rare disease, further clinical studies will only be possible, when international collaborative groups will join forces in order to perform clinical trials, in which different treatment options such as SLN procedure, primary radiotherapy on the groins and multimodality treatment for advanced disease will be investigated.

Abstract
AIM The radical surgical approach in the treatment of vulvar cancer patients has led to a favorable prognosis for the majority of the patients with early stage squamous cell cancer. However, the morbidity is impressive, leading to more individualized treatment. The aim of this review is to give an overview of the management of vulvar cancer. METHODS We have reviewed the literature on the modifications in treatment of vulvar cancer with the emphasis on surgery and radiotherapy for primary disease. RESULTS While surgery is the cornerstone of treatment for early stage squamous cell vulvar cancer (with wide local excision and uni- or bilateral inguinofemoral lymphadenectomy via separate incisions as standard treatment), until now there has been a limited role for primary radiotherapy although this may be an attractive alternative for the inguinofemoral lymphadenectomy in the future. The sentinel lymph node procedure with the combined technique (preoperative lymphoscintigraphy with (99m)technetium-labeled nanocolloid and Patente Blue) is a promising staging technique for patients with vulvar cancer. The clinical implementation of the sentinel lymph node procedure and the role of additional histopathological techniques of the sentinel lymph nodes have to be investigated. In advanced vulvar cancer, chemoradiation followed by surgery should be regarded as the treatment of first choice for these patients. CONCLUSIONS Due to the rarity of vulvar cancer it is quite clear that further studies will have to be performed by international collaborative groups. The sentinel lymph node procedure and primary radiotherapy are promising methods to reduce morbidity of treatment, but their safety needs to be studied in clinical trials.

Abstract
The aim of this study was to review the literature on currently available non- and minimally-invasive diagnostic methods and analysis of primary tumor characteristics for prediction of inguinofemoral lymph node metastases in patients with primary squamous cell carcinoma of the vulva. We used the English language literature in PubMed and reference lists from selected articles. Search terms included vulvar carcinoma, prognosis, lymph node metastases, ultrasound, computer tomography, magnetic resonance imaging, positron emission tomography, and sentinel lymph node. No study type restrictions were imposed. Currently no noninvasive imaging techniques exist that are able to predict lymph node metastases with a high enough negative predictive value. A depth of invasion < or =1 mm is the only histopathologic parameter that can exclude patients for complete inguinofemoral lymphadenectomy. No other clinicopathologic parameter allows exclusion of lymph node metastases with a high enough negative predictive value. The minimally invasive sentinel node procedure is a promising technique for selecting patients for complete lymphadenectomy, but its safety has not been proven yet.

Abstract
Inguinofemoral lymphadenectomy contributes to the high morbidity related to surgical treatment of vulval cancer. The objective of this study was to assess the accuracy of magnetic resonance imaging (MRI) in predicting inguinofemoral lymph nodes metastasis in women with vulval cancer. We reviewed the clinical, MRI, surgical, and pathologic findings of 59 women with vulval cancer who were treated at our institution from January 2000 to June 2004. Histology was available for 39 women who had undergone inguinofemoral lymphadenectomy. Clinical and MRI findings were compared with histology result to assess test accuracy. MRI had a positive likelihood ratio (LR+) of 4.8 (95% confidence interval of 2.7-8.6) and negative likelihood ratio (LR-) of 0.17 (0.06-0.49). It had a sensitivity of 85.7% (63.7-97), specificity of 82.1% (69.6-91.1), positive predictive value (PPV) of 64.3% (44.1-81.4), and negative predictive value (NPV) of 93.9% (83.1-98.7). Clinical examination had an LR+ of 6.1 (1.8-21.6) and LR- of 0.69 (0.5-0.96). It had a sensitivity of 35% (15.3-59.4), specificity of 94.3% (84.3-98.8), PPV of 70% (34.7-93.3), and NPV of 79.4% (67.3-88.5). Kappa statistics for interobserver and intraobserver agreement were 0.9091 and 0.8475, respectively. MRI assessment was accurate in predicting negative nodal status that is clinically useful in identifying women who can be spared inguinofemoral lymphadenectomy. It is noninvasive and is superior to clinical assessment. In clinical practice, this should encourage toward nodal sparing surgery, thus lowering surgical-related patient morbidity.

Abstract
We set out to study whether computerized tomography (CT) scanning of the vulva and the groin and groin ultrasound scanning (USS) alone or with fine needle aspiration cytology (FNAC) (USS/FNAC) influenced or could influence the surgical management of primary squamous cell carcinoma of the vulva (SCCaV). Forty-four patients underwent surgery for primary SCCaV following radiologic imaging by one or more modalities. Patient details included the clinical assessment of the carcinoma, radiologic findings, the operation performed, and whether the decision regarding the type and extent of surgery for the vulval carcinoma and, in particular, for the groin node dissection was or could be influenced by the radiologic findings. The age range was 38-87 years, with a median of 74 years. A total of 75 groin dissections were performed. Twenty-five of the 44 patients (56.8%) did not have groin node metastasis, 14 had unilateral metastasis (31.8%), and 5 (11.4%) had bilateral metastasis. All cases with histologically proven nodal status were analyzed to compare the preoperative imaging status with the histology. The calculated sensitivity, specificity, negative predictive value, and positive predictive value for CT were 58%, 75%, 75%, and 58%, for USS alone-87%, 69%, 94%, and 48%, and for USS-guided FNAC-80%, 100%, 93%, and 100%, respectively. There was no patient in whom surgical planning for the vulval carcinoma or the groin nodes was or could be altered by the CT findings. The data do not support the routine use of CT scanning in patients with primary SCCaV, either in assessment of the primary vulval carcinoma or in detecting groin nodal metastases. For the groin nodes, USS/FNAC is superior to CT in assessing disease status. In contrast to CT, USS/FNAC may have a useful clinical role in the management of the groin nodes in vulval carcinoma.

Abstract
OBJECTIVE To determine the accuracy of minimally and non-invasive tests to assess the groin node status in squamous cell vulvar cancer. METHODS A systematic review of published research from 1979 to 2004 that compares the results of tests to determine groin node status with histology at inguinofemoral lymphadenectomy was made. Studies included in the review were those that compared the index test to the standard surgical intervention of inguinofemoral lymphadenectomy and allowed the construction of two-by-two tables. From these tables, sensitivity, specificity, and the likelihood ratios (with 95% confidence intervals) were reported and, where feasible, meta-analysis was used to pool results for each test separately. Sentinel node biopsy using technetium-99m-labelled nanocolloid ((99m)Tc) had a pooled sensitivity and negative LR of 97% (91-100 95% CI) and 0.12 (0.053-0.28 95% CI), respectively, and was the most accurate test reviewed. CONCLUSION Five diagnostic tests were identified in a total of 29 studies (961 groins). Although the studies were small and the design often poor, this represents the best summary of the data to date. Sentinel node identification using (99m)Tc appeared to be the most promising test for accurately excluding lymph node metastases in squamous cell vulvar cancer and potentially reducing the radicality of surgery. Its efficacy as a tool in reducing the need for radical surgery and associated patient morbidity without reducing survival needs further assessment probably in a randomised control trial.

Abstract
OBJECTIVES There is an increasing interest among gynecologic oncologists to implement the sentinel lymph node (SLN) procedure in vulvar cancer patients in clinical practice. However, the safety of this promising method of staging still has to be proven in a randomized trial. MATERIALS AND METHODS Two vulvar cancer patients are reported to illustrate pitfalls in the sentinel lymph node procedure. RESULTS The phenomena of bypassing the sentinel lymph node and confusion about the number of removed sentinel lymph nodes are presented and discussed. CONCLUSION Gynecological oncologists who perform the sentinel lymph node procedure in vulvar cancer patients should perform this technique by following a strict protocol and within the protection of a clinical trial.

Abstract
PURPOSE OF REVIEW The radical surgical approach in the treatment of vulvar cancer patients has led to a favourable prognosis for the majority of patients with early stage vulvar cancer. However, morbidity is impressive, leading to more individualized treatment. The authors have reviewed the most recent literature on the pros and cons of the modifications in treatment, including surgery and primary radiotherapy, for primary squamous cell carcinoma of the vulva and vulvar melanoma. RECENT FINDINGS The sentinel lymph node procedure is a promising method of staging in patients with early stage squamous cell carcinoma of the vulva and possibly for patients with vulvar melanoma, but its safety still has to be proved. Less radical surgery has led to a higher local and regional recurrence rate. There may be a role for primary radiotherapy of the groin in a selected group of patients. SUMMARY The authors have concluded that the individualization of treatment for vulvar cancer patients has led to a decrease in morbidity but an increase in recurrences. The increase in recurrences does not appear to compromise prognosis, probably because of the lack of power, based on the low incidence of vulvar cancer. The sentinel lymph node procedure and primary radiotherapy are promising methods to reduce the morbidity of treatment but their safety needs to be studied in randomized trials.

Abstract
Detection of local or regional metastases to lymph nodes is clinically important in virtually any type of primary tumor. Current imaging techniques rely heavily on the size criterion for characterization of nodal disease. However, size can be an ineffective parameter for diagnosis of tumor spread to lymph nodes. Magnetic resonance (MR) imaging performed before and after administration of ferumoxtran-10 is a promising technique for characterization of lymph nodes in patients with various primary tumors. Normal homogeneous uptake of ferumoxtran-10 in nonmetastatic nodes shortens the T2 and T2*, turning these nodes dark, whereas malignant nodes lack uptake and remain hyperintense. To optimize acquisition strategies, the following factors should be considered: the timing of contrast material-enhanced imaging, the section thickness, the imaging plane, and the imaging parameters for T2*-weighted sequences. In addition, MR imaging with ferumoxtran-10 allows presurgical mapping of lymph nodes and quantitative estimation of T2*.
