Prognostic value of HPV-PCR, p16 and p53 immunohistochemical status on local recurrence rate and survival in patients with vulvar squamous cell carcinoma. Virchows Arch 2023:10.1007/s00428-023-03690-8. [PMID: 37938322 DOI: 10.1007/s00428-023-03690-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Revised: 10/23/2023] [Accepted: 10/26/2023] [Indexed: 11/09/2023]
Abstract
The primary aim of this study was to assess the association between human papilloma virus (HPV) and p53 expression and local recurrence (LR), disease specific survival (DSS), and overall survival (OS) in patients with vulvar squamous cell carcinoma (VSCC). Secondary, the accuracy of p16 immunohistochemistry for HPV status was assessed. The tumor tissue of 255 patients, surgically treated for primary unifocal VSCC between 2000 and 2010, was analyzed. HPV-PCR and P16 and p53 immunohistochemical stainings were performed. All histologic slides were independently reviewed by two expert gyneco-pathologists. Time to first LR, DSS, and OS for the variables p16, p53, and HPV-PCR were compared using univariable and multivariable Cox-regression analyses. In 211/255 (83.5%) patients, HPV-PCR was negative. The local recurrence rate was significantly lower in patients positive with HPV-PCR (10-year LR rate 24.6%) versus negative tumors (47.5%), p = 0.004. After multivariable analyses, this difference remained significant (HR 0.23 (95% CI 0.08-0.62) p = 0.004). There was no difference in LR rate correlated to the p53 expression. DSS and OS did not significantly differ after multivariable analyses for all different subgroups. Sensitivity and specificity of p16 staining for presence of HPV detected by HPV-PCR were 86.4% and 93.8%, respectively. In conclusion, patients with HPV-negative VSCCs have significantly more LR compared to patients with HPV-positive VSCCs, and p16 immunohistochemistry is a reliable surrogate marker for HPV status. No relevant subgroup for LR or survival based on HPV/p53 status could be identified. We advise to perform an HPV-PCR or p16 IHC staining in all patients with VSCC.

Incidence of inguinofemoral lymph node metastases at the first local recurrence of vulvar cancer: a Dutch nationwide study. Br J Cancer 2023; 129:956-964. [PMID: 37507545 PMCID: PMC10491599 DOI: 10.1038/s41416-023-02373-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 06/05/2023] [Accepted: 07/18/2023] [Indexed: 07/30/2023] Open
Abstract
BACKGROUND Up to 40% of vulvar cancer patients present with local recurrence within 10 years of follow-up. An inguinofemoral lymphadenectomy (IFL) is indicated if not performed at primary treatment. The incidence and risk factors for lymph node metastases (LNM) at first local recurrence, however, are unclear. Our aim was to determine the incidence of LNM at first local recurrence, in relation to previous groin treatment and clinicopathological factors. METHODS A multicenter cohort study including vulvar cancer patients with a first macroinvasive local recurrence after primary surgical treatment between 2000 and 2015 was conducted in the Netherlands. Groin status at local recurrence was defined as positive (N+), negative (N-) or unknown (N?) and based on histology, imaging and follow-up. Patient-, tumour- and treatment characteristics of primary and recurrent disease were analysed. RESULTS Overall, 16.3% (66/404) had a N+ groin status at first local recurrence, 66.4% (268/404) N- and 17.3% (70/404) N? groin status. The incidence of a N+ groin status was comparable after previous SLN and IFL, 11.5% and 13.8%, respectively. A N+ groin status was related to tumour size (25 vs.12 mm; P < 0.001), depth of invasion (5 vs. 3 mm; P < 0.001) and poorly differentiated tumours (22.9 vs. 11.9%; P = 0.050) at local recurrence. CONCLUSIONS The incidence of LNM at first local recurrence in vulvar cancer patients was 16.3%, and independent of previous type of groin surgery. In accordance with primary diagnosis, tumour size, depth of invasion, and tumour grade were significantly associated with a positive groin status.

Abstract
Malignant vulvar melanoma (VuM) and vaginal melanoma (VaM) represent a unique subgroup of rare malignant melanomas with critical biological properties that differ from other cancers. In Japan, adequate surveys have yet to be conducted. This study aimed to elucidate the clinicopathological demographics and outcomes of VuM and VaM in Japan. This retrospective observational study included women with invasive VuM or VaM identified from older medical records in Japan. We collected clinical data and used the Kaplan-Meier method to analyze progression-free survival (PFS) and overall survival (OS). Univariate and multivariate regression models were used to identify factors significantly related to survival. We identified 217 patients, 109 (50.2%) with VuM and 108 (49.8%) with VaM. The median PFS was 16.8 months in patients with VuM [95% confidence interval (CI), 23.1-87.7] and 15.6 months in those with VaM (95% CI, 8.4-12.6). The median OS was 43.9 months (95% CI, 60-138) and 31.1 months (95% CI, 24.8-45.3) in patients with VuM and VaM, respectively. Multivariate analysis showed that a disease stage higher than stage III, based on the American Joint Committee on Cancer (AJCC) guidelines, was associated with poorer PFS [hazard ratio (HR), 2.063; 95% CI, 0.995-4.278] and an unknown surgical margin was the only independent factor influencing OS (HR, 2.188; 95% CI, 1.203-3.977). The overall outcomes of invasive VuM and VaM in Japan remain poor. AJCC staging and surgical margins were significant predictors of survival.

Abstract
BACKGROUND Vulvar melanoma is a rare malignancy with frequent recurrence and poor prognosis. National guidelines recommend wide local excision of these tumors with allowances for narrower margins for anatomic and functional limitations, which are common on specialty sites. There is presently a lack of data of margin positivity after standard excision of vulvar melanomas. OBJECTIVE We aim to evaluate the rate of positive margins after standard excision of vulvar melanomas. MATERIALS AND METHODS Retrospective cohort study of surgically excised vulvar melanomas from the NCDB diagnosed from 2004 to 2019. RESULTS We identified a total of 2,226 cases. Across surgical approaches and tumor stages, 17.2% (Standard Error [SE]: 0.8%) of cases had positive surgical margins. Among tumor stages, T4 tumors were most commonly excised with positive margins (22.9%, SE: 1.5%). On multivariable survival analysis, excision with positive margins was associated with significantly poorer survival (Hazard Ratio 1.299, p = .015). CONCLUSION We find that positive margin rates after standard excision of vulvar malignancies are higher than for other specialty site melanomas. Our data suggest that use of surgical approaches with complete margin assessment may improve local control and functional outcomes for patients with vulvar melanoma as they have for patients with other specialty site melanomas.

Abstract
RATIONALE Vulvar melanoma is a rare and aggressive tumor with a high risk of local recurrence and distant metastasis. The prognosis is poor with a 5-year overall survival rate of only 46.6%. Management of vulvar melanoma remains a clinical challenge. Recent evidences have shown that immune checkpoint inhibitors are effective in the treatment of vulvar melanoma. PATIENT CONCERNS AND DIAGNOSES A 63-year-old woman with vulvar malignant melanoma suffered inguinal lymph node metastasis after vulvectomy and chemotherapy. She underwent inguinal lymph node dissection and inguinal radiotherapy. The tumor progressed again and she received immunotherapy. INTERVENTIONS The tumor progressed again, and she was admitted to our hospital and received toripalimab combined with apatinib and abraxane. OUTCOMES After 6 cycles of immunotherapy, the efficacy achieved partial remission. And with toripalimab as maintenance therapy, the patient achieved durable antitumor efficacy and good safety. LESSONS In this rare case, the patient with metastatic vulvar malignant melanoma had durable antitumor efficacy and good safety when receiving toripalimab.

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

Abstract
Noncutaneous melanomas are rare subtypes of melanoma with high rates of metastatic disease and poor overall survival. One-third to one-half of cases are amelanotic, which may contribute to a delay in diagnosis. Immunohistochemistry staining with typical melanoma markers helps confirm the diagnosis. There is no standard staging system across mucosal melanomas. Elective nodal dissection is not recommended and there is a paucity of data to support use of sentinel lymph node biopsy. Mutational analysis should be routinely performed. Systemic therapy options include targeted inhibitors, immunotherapy, and cytotoxic chemotherapy, although further studies are needed to confirm their efficacy.

Abstract
Background Polypoid nodule growing without apparent pigmentation on the vulvar skin usually reminds us of the diagnostic pitfall, which is commonly and mistakenly diagnosed as other types of tumors. Although there are several manifestations of amelanotic melanoma are known, these malignancies are usually pigmented because they are derived from melanocytes containing melanin. However, amelanotic melanomas are easily misdiagnosed or their diagnoses were commonly delayed due to lack of pigmentation. Therefore, a solitary polypoid nodule is worth noting and further reporting. Particularly, the clinical characteristics and outcomes of the solitary polypoid nodule are rare in Asian patients. Case presentation
We presented an interesting case of a 33-year-old female with a solitary polypoid nodule without apparent pigmentation on her vulvar skin. Her medical history was unclear, no ulcer was seen in the lesion area, and dermatoscopy was indicated a possible tumorous change, which has caught the attention of clinicians, and then further examined by the pathologist. The final diagnosis was nodular malignant melanoma (NM) (Breslow thickness 9.5mm, Clark level 4). Conclusions Hence, though reviewing this case record, the relevant literature and NM-related materials, we suggest that the combination of skin imaging technology and histopathological examination could provide us a better understanding and reduce the possibility of misdiagnosis in clinic practice.

Abstract
OBJECTIVES The aims of the study were to evaluate clinicopathologic features, management, and outcomes in vulval melanoma and to review the literature. MATERIALS AND METHODS Data were collected retrospectively on patients with vulval melanoma from 2001 to 2017 in 5 gynecological oncology cancer centers (Bristol, Taunton, Truro, Plymouth, and Cheltenham). SPSS software was used for univariate and multivariate statistical analysis. Disease-specific median survival was calculated using Kaplan-Meier curves. RESULTS Forty-four patients with vulval melanoma were included, with a median age of 71 years. Forty-three of 44 had wide local excision with full inguinal lymphadenectomy if abnormal lymph nodes. Seven patients had sentinel lymph nodes. However, 2 patients with negative sentinel lymph nodes had distant recurrences within 16 months.On univariate analysis, presence of ulceration (p = .012), perineural invasion (p = .03), and area of lesion (p = .016) were associated with risk of recurrence but only presence of microsatellites (p = .01) was associated with risk of death.There were 31 deaths (70%): 29 (94%) of 31 from melanoma and 28 (64%) of 44 recurrences: 17 local (10 groin, 7 vulval) and 9 distant. Overall median survival was 32.5 months (95% CI, 17.8-46.5 months) and median recurrence-free survival 12.6 months (95% CI, 7.7-17.4 months). CONCLUSIONS This retrospective multicenter study highlights the high recurrence rate and poor prognosis of vulval melanoma. Lymph node surgery did not make any difference to recurrence-free survival or overall survival. The presence of microsatellites was associated with a statistically increased risk of death.

Abstract
BACKGROUND Primary vulvar melanoma was an aggressive and poorly understood gynecological tumor. Unlike cutaneous melanoma, the incidence of vulvar melanoma was low but the survival was poor. There were no standard staging system and no census on treatment strategies of vulvar melanoma. Therefore, we aimed to conduct and validate a comprehensive prognostic model for predicting overall survival of vulvar melanoma and provide guidance for clinical management. METHODS Patients diagnosed with vulvar melanoma between year 2004 and 2015 from Surveillance, Epidemiology, and End Result (SEER) database were randomized to training cohort and validation cohort. Multivariate survival analysis was performed to screen for independent factors of survival. A nomogram was established to predict overall survival of vulvar melanoma. Receiver operating characteristic curve and calibration plot were performed to verify the discrimination and accuracy of the model. The decision curve analysis was performed to verify the clinical applicability of the model. RESULTS Total 737 patients with vulvar melanoma were randomized to the training cohort (n = 517) and the validation cohort (n = 220). Nomogram including age, race, tumor site, depth of tumor invasion, lymph node status, distant metastasis, tumor size, surgery, chemotherapy and radiotherapy was established and validated. The c-indexes for SEER stage, American Joint Committee on Cancer stage and this model were 0.561, 0.635 and 0.826, respectively. The high-risk group scored by this model had worse survival than the low-risk group (P < 0.001). Decision curve analysis revealed this model was superior in predicting survival. CONCLUSIONS Our model was deemed to be a useful tool for predicting overall survival of vulvar melanoma with good discrimination and clinical applicability. We hoped this model would assist gynecologists in clinical decision and management of patients diagnosed with vulvar melanoma.

Abstract
Vulvar cancer (VC) is a rare neoplasm, usually arising in postmenopausal women, although human papilloma virus (HPV)-associated VC usually develop in younger women. Incidences of VCs are rising in many countries. Surgery is the cornerstone of early-stage VC management, whereas therapies for advanced VC are multimodal and not standardized, combining chemotherapy and radiotherapy to avoid exenterative surgery. Randomized controlled trials (RCTs) are scarce due to the rarity of the disease and prognosis has not improved. Hence, new therapies are needed to improve the outcomes of these patients. In recent years, improved knowledge regarding the crosstalk between neoplastic and tumor cells has allowed researchers to develop a novel therapeutic approach exploiting these molecular interactions. Both the innate and adaptive immune systems play a key role in anti-tumor immunesurveillance. Immune checkpoint inhibitors (ICIs) have demonstrated efficacy in multiple tumor types, improving survival rates and disease outcomes. In some gynecologic cancers (e.g., cervical cancer), many studies are showing promising results and a growing interest is emerging about the potential use of ICIs in VC. The aim of this manuscript is to summarize the latest developments in the field of VC immunoncology, to present the role of state-of-the-art ICIs in VC management and to discuss new potential immunotherapeutic approaches.

METHODS The pre-operative chest imaging of 452 consecutively treated patients was documented with a minimal follow-up period of 2 years. MEAN OUTCOME MEASURES Incidence of pulmonary metastases, frequency of chest imaging and subsequent coincidental findings. RESULTS In total, 80.8% of patients underwent pre-operative chest imaging. Seven patients (1.9%), with a median tumour size of 80 mm, presented with pulmonary metastases. None of the patients with early stage disease and tumour size <40 mm who underwent radical local excision (RLE) with sentinel node (SN)-procedure, was diagnosed with pulmonary metastasis. Chest imaging was performed by radiography (58.9%) and computerised tomography (CT) (41.1%). Coincidental findings were reported in 40.7% of patients who underwent CT, compared with 15.8% of patients undergoing radiography, resulting in additional diagnostics in 14.7 and 19.7% and being of limited consequence for outcome in 2.9 and 3.3%, respectively. CONCLUSIONS The incidence of pulmonary metastases in patients with primary vulvar SCC is extremely low, and none in patients with early stage disease undergoing the SN procedure. Chest imaging was performed in the majority of patients and was associated with frequent coincidental findings leading to clinically irrelevant diagnostic procedures. Therefore, we recommend omitting chest imaging in patients with early stage disease and tumours <40 mm, considering chest CT only in patients with large tumours and/or advanced stage disease. TWEETABLE ABSTRACT The incidence of pulmonary metastases is 1.9%, none in early stage disease planned for SN. Omitting chest imaging in this group is advised.

Abstract
Vulvar cancer (VC) is a specific form of malignancy accounting for 5–6% of all gynaecologic malignancies. Although VC occurs most commonly in women after 60 years of age, disease incidence has risen progressively in premenopausal women in recent decades. VC demonstrates particular features requiring well-adapted therapeutic approaches to avoid potential treatment-related complications. Significant improvements in disease-free survival and overall survival rates for patients diagnosed with post-stage I disease have been achieved by implementing a combination therapy consisting of radical surgical resection, systemic chemotherapy and/or radiotherapy. Achieving local control remains challenging. However, mostly due to specific anatomical conditions, the need for comprehensive surgical reconstruction and frequent post-operative healing complications. Novel therapeutic tools better adapted to VC particularities are essential for improving individual outcomes. To this end, cold atmospheric plasma (CAP) treatment is a promising option for VC, and is particularly appropriate for the local treatment of dysplastic lesions, early intraepithelial cancer, and invasive tumours. In addition, CAP also helps reduce inflammatory complications and improve wound healing. The application of CAP may realise either directly or indirectly utilising nanoparticle technologies. CAP has demonstrated remarkable treatment benefits for several malignant conditions, and has created new medical fields, such as “plasma medicine” and “plasma oncology”. This article highlights the benefits of CAP for the treatment of VC, VC pre-stages, and postsurgical wound complications. There has not yet been a published report of CAP on vulvar cancer cells, and so this review summarises the progress made in gynaecological oncology and in other cancers, and promotes an important, understudied area for future research. The paradigm shift from reactive to predictive, preventive and personalised medical approaches in overall VC management is also considered.

Abstract
Metastatic vulvar melanoma is a rare and aggressive disease and survival is usually poor. Vulvar melanomas harbor BRAF V600 mutations only infrequently; consequently, target therapy is a rare therapeutic option and immunotherapy usually has only a weak effect. On the other hand, KIT mutations are rare in cutaneous melanomas, but relatively frequent in mucosal melanomas, particularly in vulvar-vaginal melanomas, and can be a therapeutic target. Herein, we report a clinical case of a patient with metastatic vulvar melanoma, harboring an exon 17 c-KIT mutation, treated with avapritinib (BLU-285) – a highly potent and selective oral kinase inhibitor designed to treat imatinib-resistant gastro-intestinal stromal tumors (GIST) by targeting KIT/PDGFRα activation loop mutants (exons 17/18). After failure of the combination of ipilimumab + nivolumab first and then nivolumab alone, the patient received avapritinib 300 mg/daily for central nervous system (CNS), lymph-nodal, right adrenal gland, lung, and subcutaneous metastases. Best response was partial remission, according to RECIST 1.1 criteria. Time to treatment progression was 11 months. Main toxicities were grade 2 cutaneous vasculitis that required avapritinib discontinuation, and grade 2 uveitis of unknown origin, treated by vitrectomy and empiric antibiotic and antiviral therapy due to negative cultural tests. Uveitis was detected at the time of progression and therapy was definitively discontinued. In conclusion, avapritinib proved to be effective even in the presence of a pretreated disease, a high tumor burden, and brain metastases. In our experience, treatment was feasible and toxicity manageable. Considering the lack of effective therapies and the poor outcome of the disease, determination of c-KIT mutations should be performed routinely in cases of metastatic mucosal melanoma.

Abstract
The risk of vulvar squamous cell carcinoma (VSCC) in patients with high-grade vulvar intraepithelial neoplasia (VIN) is considered lower in high-grade squamous intraepithelial lesion (HSIL) compared to differentiated VIN (dVIN), but studies are limited. Our study investigated both the incidence of high-grade VIN and the cumulative incidence of VSCC in patients with HSIL and dVIN separately. A database of women diagnosed with high-grade VIN between 1991 and 2011 was constructed with data from the Dutch Pathology Registry (PALGA). The European standardized incidence rate (ESR) and VSCC risk were calculated, stratified for HSIL and dVIN. The effects of type of VIN (HSIL vs dVIN), age and lichen sclerosis (LS) were estimated by Cox regression. In total, 1148 patients were diagnosed with high-grade VIN between 1991 and 2011. Between 1991-1995 and 2006-2011, the ESR of HSIL increased from 2.39 (per 100 000 woman-years) to 3.26 and the ESR of dVIN increased from 0.02 to 0.08. The 10-year cumulative VSCC risk was 10.3%; 9.7% for HSIL and 50.0% for dVIN (log rank P < .001). Type of VIN, age and presence of LS were independent risk factors for progression to VSCC, with hazard ratios of 3.0 (95% confidence interval [CI] 1.3-7.1), 2.3 (95% CI 1.5-3.4) and 3.1 (95% CI 1.8-5.3), respectively. The incidence of high-grade VIN is rising. Because of the high cancer risk in patients with dVIN, better identification and timely recognition are urgently needed.

Abstract
Background Vulvar melanoma (VuM) and vaginal melanoma (VaM) represent a unique subgroup of malignant melanomas with important differences in biology and treatment. Objective The objective of this study was to describe the epidemiology and prognosis of VuM and VaM in a large representative cohort. Methods Women with invasive VuM or VaM were identified from the Surveillance, Epidemiology and End Results-18 population representing 27.8% of the US population. Data on age, ethnicity, stage, location, histopathology, primary surgery, and lymphadenectomy were collected. The Kaplan–Meier method was used to analyze disease-specific and overall survival. Univariate and multivariate regression models were used to identify factors with a significant association with disease-specific survival. Results A total of 1400 VuM and 463 VaM were included for further analysis; 78.6% and 49.7% of women with VuM and VaM underwent surgery, but only 52.9% of women with non-metastatic VuM and 42.9% of women with non-metastatic VaM undergoing surgery had lymph node assessment; one third of these had positive nodes. Superficial spreading was the most common subtype in VuM, and nodular melanoma in VaM (p < 0.001). The median disease-specific survival was 99 months (95% confidence interval 60–138) and 19 months (95% confidence interval 16–22), respectively. Survival was significantly associated with age at diagnosis, ethnicity, stage, surgery, lymph node metastases, histologic subtype, ulceration, mitotic count, and tumor thickness in VuM, and stage, surgery, and lymph node involvement in VaM. In the Cox model, lymph node status and number of mitoses remained independent predictors of outcome in VuM; in VaM, only lymph node status remained significant. Conclusions The overall prognosis of VuM and VaM remains poor. The American Joint Committee on Cancer staging system is applicable and should be used for VuM; however, lymph node status and mitotic rate are the most important predictors of survival. Lymph node status should be assessed and patients with positive nodes may be candidates for adjuvant treatment.

Abstract
Vulvamalignome stellen die vierthäufigste Gruppe von gynäkologischen Krebserkrankungen dar. Erste Ansprechpartner sind typischerweise niedergelassene Dermatologen und Gynäkologen. Mit der jeweiligen Fachexpertise findet die Diagnose und Therapie idealerweise interdisziplinär zwischen spezialisierten Dermatoonkologen und gynäkologischen Onkologen statt. Vulvamalignome sind überwiegend Erkrankungen des höheren Lebensalters, obwohl alle histologischen Subtypen auch bei Frauen unter 30 Jahren vorkommen. Die Diagnose erfolgt oft verzögert. Eine genaue Kartierung von Biopsien (Mapping) ist von großer Bedeutung, da Lokalisation und Entfernung von der Mittellinie in Abhängigkeit von der zugrunde liegenden Histologie das operative Vorgehen bestimmen. Plattenepithelkarzinome machen mehr als 76 % der Vulvamalignome aus und vulväre intraepitheliale Neoplasien (VIN) sind dabei wichtige Vorstufen. Der zweithäufigste Typ der Vulvakarzinome ist das Basalzellkarzinom. Melanome machen 5,7 % der vulvären Malignome aus und ihre Prognose ist schlechter als die der kutanen Melanome. Die meisten Studien zu Checkpoint-Inhibitoren und zielgerichteten Therapien haben Patientinnen mit vulvären Melanomen nicht ausgeschlossen. Die vorliegende Evidenz wird im folgenden diskutiert. Die Methode der Wahl bei lokal resezierbaren Vulvamalignomen ist die Exzision. Angesichts ihrer Seltenheit sollte die Behandlung in spezialisierten Zentren erfolgen, um eine optimale Krankheitskontrolle zu erreichen und Kontinenz und sexuelle Funktion bestmöglich zu erhalten.

Abstract
Vulvar cancer represents the fourth most common gynecologic malignancy and is often encountered by the general Dermatologist or Gynecologist. Dermatooncologists and Gynecologic Oncologists share expertise in this field and the diagnosis and treatment should ideally be interdisciplinary. All subtypes are typically seen in the later decades of life, although all histologic subtypes have been described in women younger than 30 years. The diagnosis is often delayed. Exact mapping of biopsies is of high importance, as the location and distance from the midline guides the surgical approach depending on the underlying histology. Squamous cell carcinoma accounts for more than 76 % of vulvar cancer with vulvar intraepithelial neoplasia being an important precursor. Basal cell carcinoma is the second most common vulvar malignancy. Melanoma accounts for 5.7 % of vulvar cancer and has a worse prognosis compared to cutaneous melanoma. Most of the trials on checkpoint inhibitors and targeted therapy have not excluded patients with vulvar melanoma and the preliminary evidence is reviewed in the manuscript. Surgery remains the primary treatment modality of locally resectable vulvar cancer. In view of the rarity, the procedure should be performed in dedicated cancer centers to achieve optimal disease control and maintain continence and sexual function whenever possible.

Abstract
Melanoma rarely develops in the genital area. It is responsible for 5% of all vulvar malignancies. Postmenopausal women are usually more affected and the main differential diagnosis is vulvar melanosis and vulvar nevi. There are limited numbers of studies on dermoscopic features of mucosal melanoma, particularly early-stage lesions. Dermoscopic criteria have been described for the diagnosis of vulvar melanosis, and observational studies have been conducted to define the dermoscopic features of nevi and melanoma on the vulva. We are presenting the case of a 69-year old female with suspected recurrence of vulvar melanoma who previously had surgical removal of mucosal lentiginous melanoma on the left labia minor in June 2017. Five months after the primary melanoma surgery, the patient noticed de novo pigmentation at the left and right labia minor and urethral opening. On clinical examination, irregular light-brown pigmentation with ill-defined borders was evident on the labia minora of the vulva and around the external urethral orifice. On dermoscopy, irregular pigmented network, with white scar-like and structureless pinkish areas was evident. Incisional biopsy of the vulvar mucosa revealed melanoma in situ, confirming the local recurrence. CT scans of the head, thorax, abdomen and pelvis and gynaecological examination revealed no secondary deposits. Ultrasound of the regional inguinal lymph nodes revealed enlarged suspected pathologic involvement of the lymph nodes in both inguinal regions. Lymph node fine needle aspiration of lymph nodes in the left and right inguinal area revealed pleomorphic infiltrate of lymphoid cells with hemosiderin or melanoma pigment in the cytoplasm. Cystoscopic findings were within normal range. Interdisciplinary tumour board indicated wide excision of melanoma with margins of 1 cm and resection of the urethra, as well as biopsy of the enlarged left inguinal lymph node. Histopathological analysis of the resected mucosa revealed lentiginous spread of melanocytes showing moderate atypia, with focal pagetoid spread, without mitoses and ulceration and without invasion of lamina propria. The resection margins were tumour-free. Non-specific lymphadenitis was diagnosed on lymph node histopathological analysis. The patient was regularly monitored by a dermatologist and urologist, and had no recurrence. The accurate and prompt diagnosis is essential in the case of the vulvar melanoma which has unfavourable and unpredictable prognosis, with a tendency of local recurrences and regional and distant metastases in the case of invasive melanoma. In order not to miss early mucosal melanoma, dermatologists and gynaecologists should not avoid biopsy of lesions that demonstrate any clinical or dermoscopic feature of atypical melanocytic lesion, especially in case of the development of irregular pigmentation that expands and changes over time, the appearance of a solitary amelanotic papule or nodule requires excision or, in case of large diameter lesions, incision biopsies. Larger studies are needed to define more rigorously clinical and dermoscopic criteria that accurately distinguish early mucosal melanomas from benign skin lesions.

Abstract
Vulvar malignant melanoma (VMM) is a rare disease, accounting for 5% of all vulvar malignancies and is characterized by low survival and high recurrence rates. It is considered as a distinct entity of mucosal melanoma. Prognostic factors are higher age, advanced Breslow thickness, and lymph node involvement whilst central localization and ulceration status are still under debate. Surgery is the cornerstone for the treatment of primary VMM, however, it can be mutilating due to the anatomical location of the disease. Elective lymph node dissection is not part of standard care. The value of sentinel lymph node biopsy in VMM is still being studied. Radiation therapy and chemotherapy as adjuvant treatment do not benefit survival. Immunotherapy in cutaneous melanoma has shown promising results but clinical studies in VMM are scarce. In metastatic VMM, checkpoint inhibitors and in case of BRAF or KIT mutated metastatic VMM targeted therapy have shown clinical efficacy. In this review, we present an overview of clinical aspects, clinicopathological characteristics and its prognostic value and the latest view on (adjuvant) therapy and follow-up.

Abstract
The vast majority of vulvar human papilloma virus infections are produced by α human papilloma viruses and consist of exophytic or flat warts and classic or "usual" vulvar intraepithelial neoplasia. This report details 2 examples of epidermodysplasia verruciformis-like lesions of the vulva in women who were immunosuppressed. The most consistent morphologic feature was the presence of abnormal mature keratinocytes with large pale open nuclei with small nucleoli and eosinophilic cytoplasm, situated in the upper epithelial layers. In addition to these features, which are commonly seen in epidermodysplasia verruciformis-associated lesions, 1 case displayed in addition more extensively distributed abnormal nuclei, including involvement of both the upper epithelial strata and the epithelial/stromal interface. Both lesions were associated with β-papilloma virus type 5. The unique aspects of epidermodysplasia verruciformis-like lesions relative to the more common human papilloma virus infections of the vulva are highlighted and these cases illustrate the range of epithelial distribution that might be encountered in lesions involving the vulvar mucosa.

[PMID: 29728261 DOI: 10.1016/j.ygyno.2018.04.562] [Citation(s) in RCA: 43] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2018] [Revised: 04/16/2018] [Accepted: 04/17/2018] [Indexed: 12/13/2022]
Abstract
Primary melanomas originating from the gynecological tract are rare and aggressive cancers. The vulva is the most frequent site (70%), followed by vagina and more rarely by cervix. The clinical outcome of patients with female genital tract melanoma is very poor, with a 5-year overall survival (OS) of 37-50% for vulvar, 13-32% for vaginal, and approximately 10% for cervical melanoma. In this systematic review, we analyzed the pathogenesis and the different factors influencing the prognosis of melanomas of the lower genital tract, with particular emphasis on biologic variables that may influence new therapeutic approaches. We evaluated the different treatment modalities described in the literature, in order to offer a possible algorithm that may help the clinicians in diagnosing and treating patients with these uncommon malignancies.

Prognostic factors for local recurrence of squamous cell carcinoma of the vulva: A systematic review. Gynecol Oncol 2017; 148:622-631. [PMID: 29137809 DOI: 10.1016/j.ygyno.2017.11.006] [Citation(s) in RCA: 72] [Impact Index Per Article: 10.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2017] [Revised: 11/01/2017] [Accepted: 11/02/2017] [Indexed: 12/14/2022]
Abstract
BACKGROUND In patients treated for early-stage squamous cell vulvar carcinoma local recurrence is reported in up to 40% after ten years. Knowledge on prognostic factors related to local recurrences should be helpful to select high risk patients and/or to develop strategies to prevent local recurrences. OBJECTIVE This systematic review aims to evaluate the current knowledge on the incidence of local recurrences in vulvar carcinoma related to clinicopathologic and cell biologic variables. DATA SOURCES Relevant studies were identified by an extensive online electronic search in July 2017. STUDY ELIGIBILITY CRITERIA Studies reporting prognostic factors specific for local recurrences of vulvar carcinoma were included. STUDY APPRAISAL AND SYNTHESIS METHODS Two review authors independently performed data selection, extraction and assessment of study quality. The risk difference was calculated for each prognostic factor when described in two or more studies. RESULTS Twenty-two studies were included; most of all were retrospective and mainly reported pathologic prognostic factors. Our review indicates an estimated annual local recurrence rate of 4% without plateauing. The prognostic relevance for local recurrence of vulvar carcinoma of all analyzed variables remains equivocal, including pathologic tumor free margin distance <8mm, presence of lichen sclerosus, groin lymph node metastases and a variety of primary tumor characteristics (grade of differentiation, tumor size, tumor focality, depth of invasion, lymphovascular space invasion, tumor localization and presence of human papillomavirus). CONCLUSIONS Current quality of data on prognostic factors for local recurrences in vulvar carcinoma patients does not allow evidence-based clinical decision making. Further research on prognostic factors, applying state of the art methodology is needed to identify high-risk patients and to develop alternative primary and secondary prevention strategies.
