Abstract
BACKGROUND vulvar cancer, once predominantly diagnosed in older women, is increasingly being diagnosed in younger individuals, due to Human Papillomavirus (HPV) infection. Our study aimed to describe the epidemiological and histopathological aspects of vulvar cancer in Togo and its associated factors. METHODS This was a cross-sectional study, conducted on vulvar cancer cases histologically diagnosed at the Pathological Laboratory of Lomé over a period of 17-years (2005-2021). Parameters investigated included age, occupation, risk factors, sample nature, macroscopic tumor aspects, histological types, therapeutic intervenions, and prognostic outcomes. RESULTS A total of 32 cases of vulvar cancer were collected, yieding an annual frequency of 1.88 cases. The average age of the patients was 48±14.12 years with extremes of 27 years and 82 years. Housewives accounted for the largest proportion of cases (37.5%). Among the 32 cases, 27 had identifiable risk factors, with HPV infection being the most prevalentr (33.3%). The ulcero-budding aspect was most frequently observed, and squamous cell carcinoma was the most common histological type, with the majority being well differentiated (89.3%). Statistically significant associations were found between risk factors and histological types, risk factors and degrees of differentiation, as well as between histological types and good differentiation of vulvar cancers. The 3-year survival was estimated at 78.13%. CONCLUSION The incidence of vulvar cancer is increasing in Togo, particularly among young, primarily due to HPV infection.

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.

Lymphoscintigraphy and sentinel lymph node biopsy in vulvar carcinoma: update from a European expert panel. Eur J Nucl Med Mol Imaging 2020; 47:1261-1274.

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
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.

Sentinel lymph node biopsy in vulval cancer: systematic review and meta-analysis. Br J Cancer 2014; 110:2837-46.

Abstract
BACKGROUND The purpose of this study was to determine the accuracy of sentinel lymph node (SLN) biopsy with technetium 99 (99mTc) and/or blue dye-enhanced lymphoscintigraphy in vulval cancer. METHODS Sensitive searches of databases were performed upto October 2013. Studies with at least 75% of women with FIGO stage IB or II vulval cancer evaluating SLN biopsy with 99mTc, blue dye or both with reference standard of inguinofemoral lymphadenectomy (IFL) or clinical follow-up were included. Meta-analyses were performed using Meta-Disc version 1.4. RESULTS Of the 2950 references, 29 studies (1779 women) were included; most of them evaluated 99mTc combined with blue dye. Of these, 24 studies reported results for SLN followed by IFL, and 5 reported clinical follow-up only for SLN negatives. Pooling of all studies was inappropriate because of heterogeneity. Mean SLN detection rates were 94.0% for 99mTc, 68.7% for blue dye and 97.7% for both. SLN biopsy had pooled sensitivity of 95% (95% CI 92-98%) with negative predictive value (NPV) of 97.9% in studies using 99mTc/blue dye, ultrastaging and immunohistochemistry with IFL as reference. Pooled sensitivity for SLN with clinical follow-up for SLN-negatives was 91% (85-95%) with NPV 95.6%. Patients undergoing SLN biopsy experienced less morbidity than those undergoing IFL. CONCLUSIONS Sentinel lymph node biopsy using 99mTC, blue dye and ultrastaging with immunohistochemistry is highly accurate when restricted to carefully selected patients, within a rigorous protocol, with close follow-up and where sufficient numbers for learning curve optimisation exist. Patients must make an informed choice between the slightly higher groin recurrence rates of SLN biopsy vs the greater morbidity of IFL.

Abstract
OBJECTIVE To explore the accuracy of sentinel lymph node (SLN) dissection in predicting regional lymph node status by using either only Technetium-99m-labelled (Tc-99m) or in combination with a blue dye in patients with squamous cell cancer of vulva. MATERIAL AND METHODS Twenty-one patients who had T1 (≤2 cm) or T2 (>2cm) tumors that did not encroach into the urethra, vagina or anus were included in the study. For the first twelve patients, Tc-99m was used for SLN identification, and the combined technique was used in subsequent patients. Preoperatively, Tc-99m and a blue dye was injected intradermally around the tumor. Following SLN dissection, complete inguinofemoral lymphadenectomy was performed. RESULTS We could detect SLN in all 21 patients (100%) by either Tc-99m or the combined method. SLN was found to be histopathologically negative in 13 groins via Tc-99m and 10 groins via the combined method. Twenty-one of these 23 (91.3%) groin non-SLN were also negative, but in two groins, we detected metastatic non-SLN. CONCLUSION Although SLN dissection appears promising in vulvar cancer, false negative cases are reported in the literature. Sentinel lymph node dissection without complete lymphadenectomy does not seem appropriate for routine clinical use, since it is known that groin metastasis is fatal.

Abstract
Malignant melanoma of the urethra is a rare tumour that is difficult to diagnose and treat, resulting in a poor prognosis. In this paper, we present the case of a 65-year-old woman who was referred to a gynaecologist because of a urethral mass that mimicked a caruncle. The tumour was removed by local excision, and a pathological analysis revealed a malignant melanoma. Distal urethrectomy was performed after three months with no evidence of residual tumour. There was no evidence of disease at a six-year followup. In this paper, we compare the epidemiology, treatment, staging, and prognosis of vulvar cancer in general to malignant melanoma of the vulva in particular.

Abstract
OBJECTIVES Vulvar cancer is usually treated with vulvectomy and bilateral groin lymphadenectomy, which result in serious morbidities while only 30% of patients have positive nodes. The sentinel node technique has good sensitivity and specificity for detecting lymph node involvement while minimizing postoperative morbidity. The aim of this study was to evaluate the specific and overall survival impact of sentinel lymph node procedure versus inguinofemoral lymphadenectomy in patients with vulvar cancer. PATIENTS AND METHODS This is a retrospective study from the Surveillance, Epidemiology, and End Results (SEER) database on patients with vulvar squamous cell carcinoma, T1 or T2 stage, metastatis-free, followed between 2004 and 2008. RESULTS One thousand and thirty eight patients had a systematic groin lymphadenectomy and 56 a sentinel node technique (including 22 with an associated lymphadenectomy because of a positive sentinel node). There is no significant difference in overall or specific survival between the two groups. In multivariate analysis, age, T stage and nodal status are prognostic factors for overall and specific mortality (P<0.05). DISCUSSION AND CONCLUSION Sentinel node technique is not associated with an excess risk of mortality or recurrence.

Abstract
OBJECTIVES To determine the accuracy of sentinel lymph node (SLN) detection in vulval carcinoma and to report the reliability and safety of this procedure. METHODS/MATERIALS For a period of 6 years, we recruited women undergoing surgery for vulval carcinoma. All women had a preoperative biopsy confirming the depth of invasion greater than 1 mm. Sentinel lymph node detection was performed using the combined method (Tc-99m and methylene-blue dye). The standard management included complete inguinofemoral lymphadenectomy. When inguinofemoral lymph nodes were found grossly to be enlarged, these nodes were debulked, and the women subsequently treated with radiotherapy with or without chemotherapy. During the last 2 years of the study, a selected group of women had an SLN dissection alone. The SLNs were ultrastaged when they were negative on routine hematoxylin and eosin examination. RESULTS Among 60 women undergoing SLN detection, SLN was detected in 59 women (98.3%) with combined method. Blue dye did not detect an SLN in 3 women resulting in a 93.3% detection rate. The median SLN count was 2 nodes (range, 1-9). Of the 60 women, 41 had inguinofemoral lymphadenectomy, 4 had only enlarged inguinofemoral nodes debulked, and 15 had the SLN only removed. The non-SLN count was 9 nodes (range, 3-17). There were no false-negative SLNs. Twenty-one women (35%) had positive nodes on final histology. Ultrastaging increased detection of metastases in 6.9% of nodes relative to routine hematoxylin and eosin examination and upstaged 12% of women. The median follow-up was 24 months (range, 2-66 months). CONCLUSIONS Sentinel lymph node detection is safe and accurate in assessing lymph node status in women with vulval cancer undergoing staging. The combined method using Tc-99m and methylene blue dye injection for SLN detection has the best detection rate. Routine ultrastaging of negative SLN improves the detection of nodal metastases.

Abstract
BACKGROUND Nodal involvement is one of the most significant prognostic factors in early-stage vulvar cancer. AIMS To determine the diagnostic accuracy of sentinel lymph node (SLN) detection in early-stage vulvar cancer and to describe the characteristics of metastatic lymph node involvement. METHODS Of 23 women with early-stage squamous cell vulvar cancer included in the study, five had lateral lesions and 18 had midline lesions. SLN detection was performed by using a radioactive tracer and blue dye, followed by radical vulvectomy or radical wide excision with uni/bilateral inguinofemoral lymphadenectomy, depending on tumour size and localization. SLNs were subsequently examined with haematoxylin-eosin and immunohistochemistry. RESULTS The SLN detection was successful in all 23 women (100%) and in 38 of 41 groins (92.3%) tested. The total number of SLNs was 67, with an average of 1.76 per groin. In total, 20 positive SLNs were detected in 14 of 23 patients. From a total of 20 positive SLNs, micrometastases were found in five SLNs and isolated tumour cells in one SLN. We experienced one case with a false negativity of SLN. Sensitivity, negative predictive value, accuracy and false negativity of SLN detection were 93.3%, 88.8%, 95.6% and 7.1% respectively. CONCLUSION The SLN biopsy performed by an experienced team is a feasible method, with high accuracy in patients with early-stage vulvar cancer. Prognostic value of micrometastases should be confirmed in further studies.

Abstract
OBJECTIVE The purpose of the study was to determine the feasibility and accuracy of the sentinel lymph node (SLN) identification in vulvar carcinoma patients. METHODS Sixty-two patients with clinical early stage vulvar cancer underwent SLN detection procedure, followed by a complete inguinofemoral lymphadenectomy. The SLN was identified intraoperatively using lymphoscintigraphy with technetium-99m as well as patent blue V staining. The resected lymph nodes (LN) were submitted for histological examination by hematoxylin-eosin staining (H-E) and cytokeratin immunohistochemistry (IHC) and examined by the reverse transcriptase-polymerase chain reaction (RT-PCR) assay. RESULTS A total of 109 inguinal LN were dissected in 56 patients. SLNs were identified in 76% groins with patent blue V and in 99% with the use of Tc-99m. The accuracy differed significantly (p<0.0001). An H-E examination combined with IHC revealed 7 false-negative SLNs. The sensitivity of this method was 73% (95% CI, 64% to 81%) and the negative predictive value for a negative SLN finding was 92% (95% CI, 87% to 97%). The RT-PCR assay showed 8 false-negative SLNs. The sensitivity of the RT-PCR-based assay was 83% (95% CI, 75% to 90%) and the negative predictive value for a negative SLN was 88% (95% CI, 82% to 94%). The two diagnostic methods were found not to differ significantly. CONCLUSIONS In SLN mapping, the Tc-99m colloid lymphoscintigraphy is superior to the blue dye staining. Our data do not support the concept of the SLN identification as a highly accurate procedure in predicting the inguinofemoral LN status in patients with early stage vulvar cancer.

Abstract
Treatment for early-stage vulvar carcinoma has evolved from radical en bloc dissection to wide local incision with lymphadenectomy through separate groin incisions, to sentinel lymph node biopsy (SLNB). The morbidity of SLNB is far less than traditional inguinofemoral lymphadenectomy, with less lymphedema and sensory deficit, shorter hospital stays and fewer infections. A multidisciplinary approach is required, with success of the SLNB technique maximized when radiolabeled colloid is used, with blue dye added when further identification is needed. Frozen-section analysis, followed by ultrastaging of the nodal sample, minimizes the need for reoperations and decreases the risk of false negatives. We believe that SLNB will become the standard of care for treatment of early-stage vulvar carcinoma.

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
Primary or metastasic breast-like carcinoma of the vulva is a rare event. Because of the similarity with breast ductal carcinoma, we think that the same principles used for treatment of orthotopic breast cancer can be applied, as well as the use of sentinel lymph node technique, which is widely accepted in the management of early-stage breast cancer. We report a 49-old-year postmenopausal woman who was referred to our institution after small biopsy of a 3.5- × 3-cm right vulvar tumor. Histopathologically, infiltration of the vulvar dermis by a ductal carcinoma of mammary gland type was reported. At operation, the sentinel node technique revealed two sentinel nodes in the right inguinal area. Although these nodes proved negative for malignancy, the patient underwent wide local excision of tumor and complete ipsilateral inguinofemoral lymphadenectomy. The remaining excised nodes were negative. Surgical specimen proved estrogen- and progesterone-positive receptors, the reason for which the patient received tamoxifen adjuvant therapy. This report represents the first case in the world literature of primary breast carcinoma arising in the vulva in which sentinel lymph node identification has been possible. Because of the rarity of this condition, the pathologic similarity of this tumor along with currently accepted guidelines for the management of breast cancer supports the possibility of local excision and sentinel lymph node identification as a possible alternative to inguinofemoral lymphadenectomy
