Abstract
INTRODUCTION Vulval cancer is a rare gynaecological malignancy. In this study, we present a tertiary centre case analysis to examine the recurrence patterns and survival outcomes of vulval squamous cell carcinoma (SCC). METHODS This is a retrospective cohort study of women who received treatment at Oxford University Hospitals between February 2010 and July 2022 for primary vulval SCC. RESULTS We included 98 cases. The median age at diagnosis was 68 years. Human Papillomavirus (HPV) infection and lichen sclerosis were observed in 21 and 50 cases, respectively. Surgical excision was the primary treatment. Recurrence within 2 years was more common with advanced stage (p = 0.047, RR = 2.26) and extracapsular lymph node spread (p = 0.013, RR = 2.88). Local recurrence was not associated with a specific cut-off value for tumour-free margin. Poor survival outcomes were observed with higher grade (p = 0.01), advanced FIGO stage (p < 0.001), HPV-independent cancer (p = 0.048), lymph node involvement (p < 0.001, HR = 7.14), extracapsular spread (p < 0.001, HR = 7.93), lymphovascular space invasion (p = 0.002, HR = 3.17), tumour diameter wider than 23 mm (p = 0.029, HR = 2.53) and depth of invasion more than 6 mm (p = 0.006, HR = 3.62). Perineural invasion is associated with shorter disease-free survival. Five-year cancer-specific survival rates for stages I, III, and IV were 90.2%, 40.8%, and 14.3%, respectively. CONCLUSION

Abstract
OBJECTIVE The study aimed to evaluate the accuracy of perineural invasion (PNI) diagnosis in cervical cancer, and to analyze the impact of PNI on the prognosis and postoperative adjuvant treatment decisions for cervical cancer. METHODS A retrospective pathological review of PNI in cervical cancer was conducted from 2004 to 2016 in 15 hospitals. RESULTS This study included a total of 1208 cases, comprising 273 cases with PNI and 935 cases without. The false positive rate and false negative rate of PNI diagnosis were 5.35% (50/935) and 33.33% (91/273), respectively. Adenocarcinoma, deep stromal invasion, lymphovascular space invasion (LVSI) (+), and margin involvement were independent risk factors for PNI. Both 5-year overall survival rate (OS) and 5-year disease-free survival rate (DFS) of PNI group were worse than non-PNI group. PNI was an independent risk factor for 5-year OS and 5-year DFS. In cases receiving standard postoperative adjuvant treatment, among those with two intermediate-risk factors, both 5-year OS and DFS were worse in the PNI group. Among cases with three intermediate-risk factors or at least one high-risk factor, there was no difference in 5-year OS between the two groups, but 5-year DFS was worse in the PNI group. CONCLUSION The diagnosis of PNI in cervical cancer was not accurate. Adenocarcinoma, deep stromal invasion, LVSI, and margin involvement were independent risk factors for PNI. PNI was an independent risk factor for 5-year OS and DFS. PNI has the potential to serve as a new high-risk factor, thus providing guidance for postoperative adjuvant therapy.

Abstract
Squamous cell carcinoma of the vulva is a rare gynecologic cancer that is associated with significant patient morbidity and mortality, particularly for recurrent disease. This review summarizes the evidence and continued challenges, regarding the traditional clinicopathologic factors used to prognosticate vulvar squamous cell carcinoma. Articles published within the last 10 years (2010-2020) were identified. Relevant articles concerning the following fifteen prognostic factors were reviewed: HPV/p16 status, vulvar intraepithelial neoplasia, patient age, tumor stage, tumor grade, tumor size, depth of invasion, stromal changes, histologic patterns of invasion, lymphovascular space invasion (LVSI), perineural invasion, lymph node metastases, tumour focality, margin status and lichen sclerosus (LS). The relationship between each prognostic factor and progression-free survival (PFS) and overall survival (OS), including hazard ratios, 95% confidence intervals and p-values, were extracted.

Abstract
Perineural invasion (PNI) refers to the presence of cancer cells around or within nerves, raising the risk of residual tumor. Linked to worse prognosis in pancreatic ductal adenocarcinoma (PDAC), PNI is also being explored as a therapeutic target. The purpose of this work was to build a PNI detection algorithm to enhance accuracy and efficiency in identifying PNI in PDAC specimens. Training used 260 manually segmented nerve and tumor HD images from 6 scanned PDAC cases; Analytical performance analysis used 168 additional images; clinical analysis used 59 PDAC cases. The algorithm pinpointed key areas of tumor-nerve proximity for pathologist confirmation. Analytical performance reached sensitivity of 88% and 54%, and specificity of 78% and 85% for the detection of nerve and tumor, respectively. Incorporating tumor-nerve distance in clinical evaluation raised PNI detection from 52 to 81% of all cases. Interestingly, pathologist analysis required an average of only 24 s per case. This time-efficient tool accurately identifies PNI in PDAC, even with a small training cohort, by imitating pathologist thought processes.

Abstract
BACKGROUND As part of its mission to improve the quality of care for women with gynecological cancers across Europe, the European Society of Gynaecological Oncology (ESGO) first published in 2017 evidence-based guidelines for the management of patients with vulvar cancer. OBJECTIVE To update the ESGO guidelines based on the new evidence addressing the management of vulvar cancer and to cover new topics in order to provide comprehensive guidelines on all relevant issues of diagnosis and treatment of vulvar cancer. METHODS The ESGO Council nominated an international development group comprised of practicing clinicians who provide care to vulvar cancer patients and have demonstrated leadership through their expertize in clinical care and research, national and international engagement and profile as well as dedication to the topics addressed to serve on the expert panel (18 experts across Europe). To ensure that the statements were evidence-based, new data identified from a systematic search were reviewed and critically appraised. In the absence of any clear scientific evidence, judgment was based on the professional experience and consensus of the international development group. Prior to publication, the guidelines were reviewed by 206 international practitioners in cancer care delivery and patient representatives. RESULTS The updated guidelines cover comprehensively diagnosis and referral, staging, pathology, pre-operative investigations, surgical management (local treatment, groin treatment, sentinel lymph node procedure, reconstructive surgery), (chemo)radiotherapy, systemic treatment, treatment of recurrent disease (vulvar, inguinal, pelvic, and distant recurrences), and follow-up. Management algorithms are also defined.

Abstract
PURPOSE The present consensus statement was developed by the GINECOR working group on behalf of the Spanish Society of Radiation Oncology (SEOR). Given the lack of prospective data on the management of vulvar carcinoma, this document provides an up-to-date review of radiotherapy treatment in vulvar cancer and a series of consensus-based recommendations from a group of experts. METHODS A two-round, online modified Delphi study was conducted to reach consensus treatment recommendations in three clinical settings: 1) adjuvant treatment, 2) locally-advanced vulvar cancer (LAVC), and 3) recurrent disease. After the first round, we comprehensively reviewed the available medical literature from peer-reviewed journals to assess and define the evidence-based treatment options. In the second round, participants were asked to indicate their level of agreement with the preliminary recommendations according to the GRADE (Grade of Recommendation, Assessment, Development, and Evaluation) criteria, as follows: strongly agree; agree; neither agree nor disagree; disagree; strongly disagree. RESULTS The main recommendations were as follows: 1) following surgical resection, adjuvant radiotherapy is recommended with the presence of adverse risk factors (primarily positive margins and lymph node involvement); 2) radiotherapy (with or without chemotherapy) should be considered in LAVC; and 3) in recurrent disease, radiotherapy should be individualised on a case-by-case basis. A high level of agreement over 80% was reached. CONCLUSIONS In the absence of robust clinical data, these final recommendations may help to select the optimal radiotherapy approach for this relatively rare cancer.

Abstract
A cogent and comprehensive pathologic report is essential for optimal patient management, cancer staging, and prognostication. This article details the International Collaboration on Cancer Reporting (ICCR) process and the development of the vulval carcinoma reporting data set. It describes the "core" and "noncore" elements to be included in pathology reports for vulval carcinoma, inclusive of clinical, macroscopic, microscopic, and ancillary testing considerations. It provides definitions and commentary for the evidence and/or consensus-based deliberations for each element included in the data set. The commentary also discusses controversial issues, such as p16/human papillomavirus testing, tumor grading and measurements, as well as elements that show promise and warrant further evidence-based study. A summary and discussion of the updated vulval cancer staging system by the International Federation of Obstetricians and Gynaecologists (FIGO) in 2021 is also provided. We hope the widespread implementation of this data set will facilitate consistent and accurate reporting, data collection, comparison of epidemiological and pathologic parameters between different populations, facilitate research, and serve as a platform to improve patient outcomes.

Abstract
Perineural invasion (PNI), a sign of poor diagnosis and tumor metastasis, is common in a variety of malignant tumors. The infiltrating patterns and morphologies of tumors vary by organ and histological diversity, making PNI detection difficult in biopsy, which must be performed manually by pathologists. As the diameters of PNI nerves are measured on a millimeter scale, the PNI region is extremely small compared to the whole pathological image. In this study, an efficient deep learning-based method is proposed for detecting PNI regions in multiple types of cancers using only PNI annotations without detailed segmentation maps for each nerve and tumor cells obtained by pathologists. The key idea of the proposed method is to train the adopted deep learning model, U-Net, to capture the boundary regions where two features coexist. A boundary dilation method and a loss combination technique are proposed to improve the detection performance of PNI without requiring full segmentation maps. Experiments were conducted with various combinations of boundary dilation widths and loss functions. It is confirmed that the proposed method effectively improves PNI detection performance from 0.188 to 0.275. Additional experiments were also performed on normal nerve detection to validate the applicability of the proposed method to the general boundary detection tasks. The experimental results demonstrate that the proposed method is also effective for general tasks, and it improved nerve detection performance from 0.511 to 0.693.

Abstract
We searched international databases to identify evidence that refer to the impact of perineural invasion on survival outcomes of patients with squamous cell vulvar cancer. We identified six retrospective cohort studies that investigated 887 patients. Of those, 234 (26.4%) had perineural invasion in the pathology analysis. Women with perineural invasion were more likely to have inguinal lymph node metastases (HR 3.45, 95% CI 1.12, 10.67). The impact of perineural invasion on progression-free survival rates was significant (HR 1.61, 95% CI 1.21, 2.15) as well as its impact on overall survival rates (HR 2.73, 95% CI 1.94, 3.84).

Abstract
Simple Summary Vulvar squamous cell carcinoma is a rare tumor but represents a serious health issue, especially due to the increasing incidence over the past decades. Many efforts have been made to identify new prognostic and therapeutic factors and, in this context, growing evidence concerning a pivotal role of perineural invasion. With this study, we investigated the role of perineural invasion in a large cohort of FIGO stage Ib-IIIc vulvar squamous cell carcinomas and found that perineural invasion-positive tumors have more aggressive biological behaviors and showed reduced cancer-specific survival as compared to perineural invasion-negative tumors, while this feature does not appear to be related to a greater risk to develop loco-regional recurrence. Further evaluations are warranted to confirm the prognostic role of perineural invasion and its potential use to tailor adjuvant treatment. Abstract The aims of this study were to assess the prevalence of perineural invasion (PNI) in vulvar squamous cell carcinoma (VSCC) and its prognostic role in locoregional recurrence (LRR) and cancer-specific survival (CSS). We performed a retrospective analysis of 223 consecutive stage IB–IIIC surgically treated VSCCs at S. Anna Hospital, University of Turin, from 2000 to 2019. We identified 133/223 (59.6%) patients with PNI-positive VSCCs. PNI was associated with aggressive biological features (i.e., advanced FIGO stage, larger tumor diameter, greater depth of invasion, a higher number of metastatic lymph nodes, and lymphovascular invasion) and shorter 5-year CSS (78% vs. 90%, log-rank p = 0.02) compared with PNI-negative VSCCs. Multivariate analysis showed that PNI (HR 2.99 CI 95% 1.17–7.63; p = 0.02) and the presence of tumor cells on pathological surgical margins (HR 3.13 CI 95% 1.37–7.13; p = 0.007) are independent prognostic factors for CSS. PNI does not appear to be related to LRR, but is an independent prognostic factor for worse survival outcomes. Future studies are necessary to explore the possible value of PNI in tailoring the choice of adjuvant treatment.

Roy SF, Wong J, Le Page C, Tran-Thanh D, Barkati M, Pina A, Trinh VQH, Rahimi K. DEVIL, VAAD and vLSC constitute a spectrum of HPV-independent, p53-independent intraepithelial neoplasia of the vulva. Histopathology 2021; 79:975-988. [PMID: 34265101 DOI: 10.1111/his.14451] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2021] [Accepted: 07/14/2021] [Indexed: 11/30/2022]
Abstract
AIMS We aimed to characterize a large cohort of non-invasive, HPV and p53-independent verruciform lesions, such as "vulvar acanthosis with altered differentiation" (VAAD), "differentiated exophytic vulvar intraepithelial lesion" (DEVIL) and "verruciform lichen simplex chronicus" (vLSC). METHODS AND RESULTS We retrospectively identified from January 2008 until December 2020, 36 eligible patients with verruciform non-invasive lesions (n=36) and collected clinical, histological and follow-up parameters. Verruciform non-invasive lesions occurred at a median age of 71 years with a median follow-up of 33.5 months. Clinically, pruritus was only reported in patients with VAAD (n=3, 21%). Lesion color was significantly different across categories (p=0.028). Apart from the histopathological criteria already known to distinguish these entities (hypogranulosis, epithelial pallor and low-magnification architecture), no other significant criteria were discovered, and significant overlap was observed, particularly between VAAD and DEVIL. Patients with vLSC trended towards longer survival without recurrence compared to VAAD and DEVIL (P=0.082) yet showed comparable invasion-free survival interval (p=0.782). Squamous cell carcinomas (SCC) associated with either VAAD, DEVIL or vLSC displayed similar clinical, histopathological and biological parameters. In non-invasive precursor lesions, stromal edema was associated with invasion (p=0.015) and remained so upon Cox regression analysis (p=0.009). CONCLUSION Our study of HPV and p53 independent non-invasive verruciform lesions of the vulva highlights significant clinical, histopathologic and biologic overlap between VAAD, DEVIL and vLSC suggesting that these pre-invasive lesions should be viewed as a spectrum. We also show that stromal features such as edema might play an import role in progression to invasion.

Abstract
BACKGROUND/AIM The aims of the study were: i) to assess the incidence of perineural invasion (PNI) in squamous cell carcinoma of the vulva and ii) to correlate PNI with common pathological prognostic variables and clinical outcome of patients. PATIENTS AND METHODS The hospital records of 64 patients with vulvar squamous cell carcinoma who underwent primary radical surgery were reviewed. RESULTS PNI was significantly related to stage (p=0.038), size (p=0.038), lymph-vascular space involvement (p=0.013) and nodal status (p=0.038), but not to patient age, tumor grade and stromal invasion. Five-year disease-free survival was 30.0% in patients with PNI and 53.1% in those without PNI (p=0.018), and the corresponding 5-year overall survival was 50.0% and 77.1% (p=0.031), respectively. CONCLUSION PNI was associated with common pathological prognostic variables and with a poorer clinical outcome in patients with vulvar squamous cell carcinoma.

Abstract
Squamous cell carcinoma of the vulva is a rare gynecologic cancer that is associated with significant patient morbidity and mortality, particularly for recurrent disease. This review summarizes the evidence and continued challenges, regarding the traditional clinicopathologic factors used to prognosticate vulvar squamous cell carcinoma. Articles published within the last 10 years (2010-2020) were identified. Relevant articles concerning the following fifteen prognostic factors were reviewed: HPV/p16 status, vulvar intraepithelial neoplasia, patient age, tumor stage, tumor grade, tumor size, depth of invasion, stromal changes, histologic patterns of invasion, lymphovascular space invasion (LVSI), perineural invasion, lymph node metastases, tumour focality, margin status and lichen sclerosus (LS). The relationship between each prognostic factor and progression-free survival (PFS) and overall survival (OS), including hazard ratios, 95% confidence intervals and p-values, were extracted.

Abstract
Neural invasion (NI) is the invasion of cancer cells into nerves, influencing the pathological characteristics of malignant tumors. NI promotes metastasis and is associated with reduced survival of affected patients. Although known for decades, its prognostic and therapeutic implications have not been not much appreciated due to the scattered information available on its clinical complications. The use of multiple nomenclatures to describe NI also generated confusions among researchers to understand this pathological process. Here, we discuss the multiple classifications of NI and review its clinical complications. Recent findings of the regulatory roles of nerves on tumor growth have fuelled research in this field, and there has been several attempts to molecularly define the NI interface and the cancer cells involved. Therefore, in this review, we discuss the large datasets available to characterize the cancer cells in NI and also discuss the roles of Schwann cells and macrophages participating in NI.

Abstract
OBJECTIVE to assess the prognostic role in recurrence and survival of perineural invasion (PNI) in vulvar squamous cell cancer (VSCC). METHODS Patients underwent primary surgery for VSCC from January 2009 to December 2016 served as the study cohort. We collected demographic, clinical, pathological characteristics and follow-up data, and we compared them among PNI-negative versus -positivepatients. We calculated disease-free survival (DFS) and overall survival (OS) using Kaplan-Meier and univariate log-rank test. We conducted a multivariate analysis with cox-proportional hazard models for DFS and OS, including age, tumor size, depth of invasion, free tumor margin <8 mm, high-grade histology, lymph vascular space invasion, PNI, extracapsular lymph nodal disease, lymph nodal ratio >0.2 and FIGO Stage 2009 (Early I-II versus Advanced III-IV). RESULTS We found 74 patients with a PNI prevalence of 31.1%. The 5-year DFS was favourable for PNI-negative patients (72% versus 18%; p = 0.00). The 5-year OS was 75% versus 35% in favor of PNI-negative patients (p = 0.00). The subgroup analysis conducted among stage confirmed a decreased DFS and OS in PNI-positive patients. Multivariate analysis showed that PNI (HR 2.74; CI95% 1.10-7.13; p = 0.03) and extracapsular lymph nodal disease (HR 13.54; CI95% 2.87-64.07; p = 0.01) are independent prognostic factors for earlier recurrence. OS was significantly reduced in case of PNI (HR 4.93; CI95% 1.33-18.35; p = 0.01) and extracapsular lymph nodal disease (HR 10.63; CI95% 1.65-68.57; p = 0.01). CONCLUSIONS PNI is an independent prognostic factor for aggressive behavior and unfavorable course in VSCC and should be considered in adjuvant treatment planning.

Abstract
Background: Perineural invasion (PNI) is closely associated with poor survival in several types of malignant tumours, but whether this is true in vulvar squamous cell carcinoma (VSCC) is unclear. The aims of this study were to determine the prognostic significance of PNI in patients with VSCC. Patients and methods: We retrospectively analysed clinico-pathological data on 105 patients with VSCC (stages IB-IV) treated surgically at our medical center between 2005 and 2015. Results: PNI was detected in 30 (28.6%) patients, and it was significantly associated with well-known clinical risk factors: large tumour size, depth of invasion, lymphatic vascular space invasion (LVSI), and intra- or extra-nodal spread. Significantly greater proportions of patients with PNI received adjuvant therapy after surgery (P=0.001) or showed local recurrence (P=0.002). Multivariable analysis indicated that risk factors for disease-free survival were tumour size (HR 3.02, 95%CI 1.75-7.75), LVSI (HR 4.82, 95%CI 1.36-17.07), depth of invasion (HR 3.11, 95%CI 1.50-6.44), lymph node metastasis (HR 3.15, 95%CI 1.14-8.96) and positive or close surgical margins (HR 4.86, 95%CI 1.67-14.19). The latter three variables were also risk factors for overall survival. PNI was associated with significantly shorter disease-free survival (DFS) (P=0.020) and overall survival (OS) (P=0.017) based on the log-rank test. Among patients who received adjuvant treatment, Kaplan-Meier curves indicated no significant differences between PNI-positive or -negative subgroups in disease-free survival (P=0.085) or overall survival (P=0.061). Based on multivariable analysis of all patients, PNI was not a significant risk factor for either type of survival . Conclusion: PNI in VSCC is associated with significantly shorter disease-free and overall survival, though it appears to be a weak independent predictor of worse prognosis. Combining PNI with other risk factors may be useful for predicting whether postoperative adjuvant therapy will be needed.

Perineural invasion (PNI) in vulvar carcinoma: A review of 421 cases. Gynecol Oncol 2018; 152:101-105. [PMID: 30396690 DOI: 10.1016/j.ygyno.2018.10.035] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2018] [Revised: 10/18/2018] [Accepted: 10/23/2018] [Indexed: 11/22/2022]
Abstract
OBJECTIVES To evaluate the prevalence and associated prognostic indicators in patients with vulvar carcinoma with and without evidence of perineural invasion (PNI). METHODS A retrospective review identified 421 patients with invasive vulvar carcinoma evaluated at a single institution between 1993 and 2011. Medical records were reviewed for demographic data, pathologic information and presence or absence of PNI, treatment type, and recurrence/outcome information. Variables were compared between patients with PNI to those without PNI. RESULTS Of the 421 patients included in the study, 32 (7.6%) had tumors with PNI. There were no significant differences in age, race/ethnicity, smoking history, histologic subtype, or grade between the group of patients with PNI and the group without PNI. The group with PNI was more likely to have lichen sclerosus (25.0% vs. 15.4%, p = 0.024), stage III/IV disease (59.4% vs. 36.0%, p = 0.007), lymph node involvement (50.0% vs. 21.6%, p = 0.002), and lymphovascular space invasion (LVSI) (53.1% vs. 15.9%, p < 0.001). A higher proportion of patients in the PNI group underwent primary or adjuvant radiation therapy (68.8% vs. 45.0%, p = 0.016). The median follow-up was 67.1 months (range < 1.0 to 284.3). Patients with PNI had significantly shorter overall survival (OS), median 25.5 vs. 94.3 months (p < 0.001), and progression-free survival (PFS), median 17.5 vs. 29.0 months (p = 0.004). After adjusting for stage, patients with PNI had a greater risk for death and progression (OS: hazard ratio, 2.71; p < 0.001; PFS: hazard ratio, 1.64; p-value = 0.020). CONCLUSION PNI should be considered an independent poor prognostic factor for patients with vulvar carcinoma, and should be included as part of the pathologic analysis.

Clin Proteomics 2017; 14:40. [PMID: 29225558 PMCID: PMC5717999 DOI: 10.1186/s12014-017-9175-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2017] [Accepted: 11/25/2017] [Indexed: 02/08/2023] Open
Abstract
Background Vulvar squamous cell carcinoma (vSCC) is a rare but debilitating disease. One vSCC variant comprises tumor cells that grow and expand as a cohesive sheet of cells that “pushes” and compresses the associated lymphoplasmacytic (LPC) stroma. Another vSCC variant features tumor cells that grow in loose association with one another and infiltrate the associated fibromyxoid (FMX) stroma consisting mainly of extracellular matrix. Clinically, infiltrative vSCC with FMX stroma (Inf/FMX) is significantly associated with lymph node metastases and recurrence. Methods An unbiased proteomic approach was used to identify pathways involved in the development of the different vSCC variants. Proteins extracted from formalin-fixed and paraffin-embedded tissues of 10 cases of pushing vSCC with LPC stroma (Push/LPC) and eight cases of Inf/FMX were subjected to liquid chromatography-tandem mass spectrometry (LC–MS/MS). Results Analysis identified 2265 different proteins in the 18 samples of vSCC. Of these, 282 proteins were differentially expressed between vSCC variants. Of these, 45 were higher and 237 lower in Inf/FMX compared to Push/LPC tumors. Consistent with the desmoplastic morphology and increased picrosirius red staining, expression of subunits of several collagens (Col 1, 3, 6, 14) was higher in the more aggressive Inf/FMX tumors. In contrast, signal transducer and activator of transcription 1 (STAT1), an important regulator of several inflammatory pathways, was expressed at lower levels in the Inf/FMX tumors. This finding was confirmed by immunohistochemistry using an antibody to STAT1. Informatics analysis of the differing profiles identified differences in pathways associated with integrin signaling and inflammation mediated by chemokines and cytokines. Conclusions Comparing the proteomic profiles of vSCC morphologic variants indicates that increased expression of collagen subunits and decreased expression of STAT1 are associated with a more aggressive tumor variant, defined by increased incidence of nodal metastases and tumor recurrence. Informatic analyses further identify that both alterations in cell interaction with matrix and immune function differ with tumor aggressiveness. Identification of these pathways provides a molecular basis for understanding aggressiveness of vSCC.

Abstract
Vulvar cancer accounts for 5% of the female genital tract cancers. Cutaneous metastases from vulvar cancer are extremely rare and for this reason, it can be difficult to reach a diagnosis with a consequent delay in the treatment. A systematic literature review of articles on this subject was conducted through a MEDLINE-based search for articles published in English or French. To date, 16 cases (including ours unpublished) of cutaneous metastasis from vulvar cancer have been reported. Cutaneous metastasis can occur from any stage of vulvar cancer, even after a short period. Different treatments have been described but none of them seems to be more effective. In all reported cases the prognosis was very poor. Every time a vulvar cancer survivor shows a suspicious cutaneous lesion, this should be biopsied to exclude skin relapse. Impact statement Cutaneous metastases from vulvar cancer are extremely rare and due to its rarity, a standard treatment has not been established yet. Cutaneous metastasis can occur from any stage of vulvar cancer, even after a short period. In all the reported cases, the prognosis was very poor. Every time a vulvar cancer survivor shows a suspect cutaneous lesion, this should be biopsied to exclude skin relapse.

Abstract
Recurrent disease occurs in 12-37% of patients with vulvar squamous cell carcinoma (VSCC). Decisions about treatment of recurrent VSCC mainly depend on the location of the recurrence and previous treatment, resulting in individualized and consensus-based approaches. Most recurrences (40-80%) occur within 2 years after initial treatment. Currently, wide local excision is the treatment of choice for local recurrences. Isolated local recurrence of VSCC has a good prognosis, with reported 5-year survival rates of up to 60%. Groin recurrences and distant recurrences are less common and have an extremely poor prognosis. For groin recurrences, surgery with or without (chemo) radiotherapy is a treatment option, depending on prior treatment. For distant recurrences, there are only palliative treatment options. In this review, we give an overview of the available literature and discuss epidemiology, risk factors, and prognostic factors for the different types of recurrent VSCC and we describe treatment options and clinical outcome.

Abstract
Factors contributing to aggressive behavior in vulvar squamous cell carcinoma (vSCC) are poorly defined; however, a recent study has shown that vSCCs with an infiltrative pattern of invasion and fibromyxoid stroma are associated with worse outcomes than tumors with a pushing or nested pattern of invasion and lymphoplasmacytic stroma. Epithelial-mesenchymal transition (EMT) has been associated with tumor progression in a number of malignancies, and this study proposes that EMT contributes to tumor aggressiveness in this subset of vSCC. Immunohistochemistry was used to detect nuclear localization of β-catenin, loss of E-cadherin, and presence of vimentin in 58 cases of vSCC. The association of these phenotypic changes with pathologic features and clinical outcomes was tested using Fisher's exact and χ(2) analyses (significance at P≤.05). EMT-associated features were identified in 45 of 58 cases (78%) with 28 cases exhibiting more than one feature. Nuclear β-catenin and presence of vimentin were significantly more likely to occur in tumors with an infiltrative pattern of invasion or a fibromyxoid stromal response. Loss of E-cadherin was significantly associated with an infiltrative pattern, but not a fibromyxoid stroma. Risk for tumor recurrence was significantly increased in tumors with nuclear localization of β-catenin alone or in tumors displaying multiple EMT-associated features. These results suggest that the development of EMT may be a mechanism by which infiltrative vulvar tumors with a fibromyxoid stromal response behave more aggressively and convey worse outcomes than tumors that do not exhibit these pathologic features.
