To assess clinical outcomes of inguinal lymph node surgical resection compared to primary groin radiotherapy for locally advanced, surgically unresectable vulvar cancer. All patients treated with radiation for vulvar cancer were identified between Jan 1, 2000 - Dec 31, 2020 at 2 academic centres. Inclusion criteria were those treated with curative intent primary radiotherapy +/− chemotherapy, tumors >4 cm, and surgically unresectable squamous cell vulvar carcinoma. Groin recurrence-free survival (RFS) was compared for groin surgery and primary groin radiotherapy using the Kaplan Meier method and log rank test. Groin failures are described by treatment modality, radiation dose and lymph node size. Of 476 patients treated with radiation for vulvar cancer, 112 patients (23.5%) met inclusion and exclusion criteria. The median (95% CI) follow up was 1.9 (1.4–2.5) years. Complete clinical response was significantly higher (80.0%) in patients with surgical groin resection compared to patients treated with primary groin radiotherapy (58.2%) (p = 0.04). On multivariable analysis, after adjusting for clinical and/or radiologically abnormal lymph nodes (p = 0.67), surgical groin resection was significantly associated with lower groin recurrence (HR 0.2 (95%CI 0.05–0.92), p = 0.04). The 3-year groin recurrence-free survival (RFS) was significantly higher at 94.4% (87.1–100) in patients with surgical groin resection compared to 79.2% (69.1–90.9) in patients treated with primary radiation (p = 0.02). In locally advanced squamous cell vulvar cancer, surgical groin management improves groin RFS compared to radiotherapy alone. • 3-year groin recurrence-free survival significantly longer with surgical groin resection compared to primary radiation. • After adjusting for abnormal lymph nodes on multivariable analysis, surgical groin resection had lower groin recurrence. • Higher radiation doses to the groin are associated with a lower rate of groin treatment failure in non-surgical candidates.

Background: The Groningen International Study on Sentinel Nodes in Vulval cancer (GROINSS-V) showed that if a sentinel lymph node (SLN) is negative, the risk of groin relapse due to a false negative finding is less than 3%. The SLN procedure (SLNP) is the standard of care in the management of early vulval squamous cell carcinoma (SCC). We aimed to evaluate the feasibility and safety of the SLNP in a low-resource setting with a high prevalence of HIV and human papillomavirus (HPV)-associated vulval SCC. Methods: Between August 2012 and August 2016, women with early vulval SCC managed at Groote Schuur Hospital (GSH), Cape Town, South Africa, who fit the criteria, were offered the SLNP. For quality control, full inguinofemoral lymphadenectomy (IFL) was also done in the first 10 patients. Results: In our setting, 40% of women with vulval SCC are HIV-infected and there is a predominance of HPV-associated vulval SCC, consequently, only 10.4% (10/96) of women were suitable for the SLNP. Most patients have multifocal tumours and/or enlarged groin nodes. Women with HIV and SCC presented at a younger age than those who were HIV-negative and had more SLN, which were expensive to ultra-stage. Conclusion: At GSH, multifocal vulval SCC arising in vulval high-grade intraepithelial lesion (VHSIL) in HIV-infected women is relatively common. The main resource issue was the ultrastaging cost. However, more significant limiting factors to safely performing the SLNP were the multifocality of the disease, as well as enlarged (mainly reactive) groin lymph nodes, which could not be distinguished from metastases preoperatively. As a result, relatively few of our patients are suitable for the SLNP, so maintenance of skills is a concern. [ABSTRACT FROM AUTHOR]

Abstract Background The incidence of vulvar cancer (VC) in pregnancy is unknown due to its rarity; between 1955 and 2014 only 36 case reports were reported worldwide. Underreporting may also be a contributing factor to the unknown incidence of VC in pregnancy. The aim of this study was to analyze the diagnosis, treatment and outcome of vulvar cancer cases diagnosed during pregnancy and/or breastfeeding. Case presentation Patient 1 was diagnosed at 18 weeks’ gestation (WG) with Grade 2 VC (pT1a, pN0, 0/4 sentinel lymph nodes biopsy (SLNB) involved) and was treated by having the tumor resected (R0). She is currently recurrence-free at 4 years post-diagnosis. Patient 2 was diagnosed at 7 WG with Grade 2 VC (pT1b, pN1a, 1/17 SLNB, R0) and was treated during the first trimester and during the second trimester with SLNB. She is currently recurrence-free at 5 years post-diagnosis. Patient 3 was diagnosed at 30 WG with Grade 2 VC (pT1b, pN0, 0/5 SLNB, R0). She subsequently experienced a number of local recurrences postpartum that were managed by resection and is currently recurrence-free at 3 years post-diagnosis. Patient 4 was diagnosed a VL later, at 14 months during breastfeeding, that was diagnosed as Grade 3 VC (pT1b, pN1a, 1/14 SLNB, R0). The patient is currently recurrence-free at 9 years post-diagnosis. Patient 5 was not diagnosed during pregnancy, but was diagnosed with G3 VC (pT2, pN2c, 2/17 SLNB, R0) 8 months postpartum. The patient due to the extent of tumor involvement and lymph node metastasis, underwent chemoradiation therapy post-surgery. Despite adjuvant therapy, the patient progressed and developed bone metastases. Analysis of the tumour tissue revealed increased expression of PD-L1 (programmed cell death protein 1) indicating that the patient may have benefited from treatment with nivolumab to block the PD-L1 interaction; unfortunately the patient passed away at 24 months post-diagnosis before immunotherapy treatment could commence. Conclusion Surgical resection and simultaneous SLNB in VC cases are considered safe during pregnancy, with comparable outcomes to non-pregnant women. Prompt diagnostic workup and treatment should never be delayed during pregnancy as delayed diagnosis could lead to tumour progression with fatal consequences.

• Contralateral groin metastases or recurrences in patients with unilateral SN metastasis are rare. • Unilateral groin treatment is sufficient in patients with unilateral SN metastases. • In near-midline vulvar cancer, unilateral SN detection is sufficient when the lymphoscintigram shows unilateral lymph flow. • These findings offer further opportunity to safely reduce treatment-related morbidity in early-stage vulvar cancer. Optimal management of the contralateral groin in patients with early-stage vulvar squamous cell carcinoma (VSCC) and a metastatic unilateral inguinal sentinel lymph node (SN) is unclear. We analyzed patients who participated in GROINSS-V I or II to determine whether treatment of the contralateral groin can safely be omitted in patients with a unilateral metastatic SN. We selected the patients with a unilateral metastatic SN from the GROINSS-V I and II databases. We determined the incidence of contralateral additional non-SN metastases in patients with unilateral SN-metastasis who underwent bilateral inguinofemoral lymphadenectomy (IFL). In those who underwent only ipsilateral groin treatment or no further treatment, we determined the incidence of contralateral groin recurrences during follow-up. Of 1912 patients with early-stage VSCC, 366 had a unilateral metastatic SN. Subsequently, 244 had an IFL or no treatment of the contralateral groin. In seven patients (7/244; 2.9% [95% CI: 1.4%-5.8%]) disease was diagnosed in the contralateral groin: five had contralateral non-SN metastasis at IFL and two developed an isolated contralateral groin recurrence after no further treatment. Five of them had a primary tumor ≥30 mm. Bilateral radiotherapy was administered in 122 patients, of whom one (1/122; 0.8% [95% CI: 0.1%–4.5%]) had a contralateral groin recurrence. The risk of contralateral lymph node metastases in patients with early-stage VSCC and a unilateral metastatic SN is low. It appears safe to limit groin treatment to unilateral IFL or inguinofemoral radiotherapy in these cases. [ABSTRACT FROM AUTHOR]

Primary surgery for vulvar cancer has become less radical in past decades. This study investigates risk factors and prevalence of short-and long-term complications after up-to-date vulvar cancer surgery. Population-based cohort study of surgically treated primary vulvar cancer at a national center of vulvar cancer, assessing surgical outcome. The Swedish Quality Registry for Gynecological Cancer was used for identification, journals reviewed and surgical outcome including complications within 30 days and one year registered. Multivariable logistic regression analysis comprising risk factors of short-term complications; age>80 years, BMI, smoking, diabetes, lichen sclerosus and FIGO stage was performed. 182 patients were identified, whereas 55 had vulvar surgery only, 53 surgery including sentinel lymph node biopsy (SLNB) and 72 surgery including inguinofemoral lymphadenectomy (IFL), with short-term complication rates of 21.8%, 39.6% and 54.2% respectively. Vulvar wound dehiscence was reported in 6.0% and infection in 13.7%. Complication rates were lower after SLNB than IFL (wound dehiscence 0% vs 8.3%; p = 0.04, infection 15.1% vs 36.1%; p = 0.01 and lymphocele 5.7% vs 9.7%; p = 0.52). Severe complications were rare. Persisting lymphedema evolved in 3.8% after SLNB and in 38.6% after IFL (p = 0.001), ubiquitous after adjuvant radiotherapy. In multivariable regression analysis, no associations between included risk factors and complications were found. Surgical complications are still common in vulvar cancer surgery and increase with the extent of groin surgery. To thrive for early diagnosis and to avoid IFL seem to be the most important factors in minimizing short-and long-term complications. [ABSTRACT FROM AUTHOR]

The present article aims to highlight the importance of changes of personalized surgical treatment for vulvar cancer. Current international literature regarding surgical treatment of vulvar cancer was evaluated. This included several studies and systematic reviews. Radical surgery approach, such as en bloc resection, was the first therapeutic option and the standard care for many years, even if burdened with a high complication rate and frequently disfiguring. Taussing and Way introduced radical vulvectomy approach with en bloc bilateral inguinal‐femoral lymphadenectomy; modified radical vulvectomy was developed, with a wide radical excision of the primary tumor. The role of inguinofemoral lymphadenectomy (mono or bilateral) changed in the years too, particularly with the advent of SLN biopsy as minimally invasive surgical approach for lymph node staging, in patients with unifocal cancer <4 cm, without suspicious groin nodes. More personalized and conservative surgical approach, consisting of wide local or wide radical excisions, is necessary to reduce complications as lymphedema or sexual disfunction. The optimal surgical management of vulvar cancer needs to consider dimensions, staging, depth of invasion, presence of carcinoma at the surgical margins of resection and grading, with the goal of making the treatment as individualized as possible.

To investigate the impact of a preoperative CT on surgical decision making in primary vulvar squamous cell carcinoma (VSCC) and the accuracy of detecting inguinal lymph node metastases (LNM). Secondly to assess prevalence and consequences of incidental findings and comorbidity using a CT. This population-based study comprised of surgically treated patients with primary VSCC, at a regional tertiary center, using the Swedish Quality Registry for Gynecological Cancer for identification, and medical records were reviewed. Results from the preoperative CT was compared with the histological analysis from the lymphadenectomy in the total cohort and between tumor size <4 cm versus ≥4 cm. In total 134 women had undergone CT before sentinel node (SN) biopsy (n = 83) or inguinofemoral lymphadenectomy (IFL) (n = 51). Fiftyone patients (38%) had groin LNM. Accuracy of CT in detecting groin LNM was 76%; sensitivity 43% and specificity 96%. Positive (PPV) and negative predictive values (NPV) were 88% and 73% respectively. In tumors <4 cm (n = 87), sensitivity, specificity, PPV and NPV were 17%, 95%, 57% and 75% and in tumors ≥4 cm (n = 47) 67%, 100%, 100% and 69% respectively. CT altered surgical method from SN biopsy to IFL in only two cases. Incidental findings led to extra follow-up resulting in a benign diagnosis in 22 patients and major important findings in five patients. In primary VSCC, a preoperative abdominal-inguinal CT is of limited value for surgical decision making. In tumors <4 cm, it may be omitted due to low diagnostic accuracy and disturbing incidental findings. • Preoperative CT did not have an impact on the surgical decision making in primary vulvar cancer. • Distant metastases were rare and only found in patients with confirmed groin metastases. • In vulvar cancer tumors <4 cm preoperative CT can be excluded due to low diagnostic accuracy and disturbing incidental findings.

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

Purpose: Despite the introduction of sentinel node biopsy in patients with vulvar cancer, still approximately 50% of all patients have to undergo an inguinofemoral lymphadenectomy. This is associated with a high incidence of postoperative complications, which may be influenced by inguinal drain management. The aim of this study was to investigate the feasibility of a new surgical technique regarding drain management with an inguinoperitoneal drainage.Methods: A retrospective analysis of 21 vulvar cancer patients with inguinofemoral lymphadenectomy was conducted. A silicone drain was circularly placed with the perforated end in the groin and the other end in the space of Douglas. The removal after 3 months was performed under local anesthesia. All patients were questioned during clinical follow-up regarding their personal experiences with the procedure, the occurrence of complications, and side effects using a clinical questionnaire.Results: In 100% of the patients, the procedure was feasible. Regarding the number of groin punctures due to lymphocyst formation, 15 (71.4%) patients did not need any intervention and 3 (14.3%) patients needed 1-3 punctures. The patient satisfaction with the internal drainage was ranked as good by 17 (81.0%) patients and as moderate by 1 (4.8%) patient. In 3 (14.3%) patients, information about the number of groin punctures and the patient satisfaction were missing.Conclusion: Inguinoperitoneal drainage after inguinofemoral lymphadenectomy in vulvar cancer patients is feasible and safe and a patient satisfaction of 81% is promising. For definitive conclusions regarding the efficacy of this technique, further investigations and prospective multicenter trials are needed. [ABSTRACT FROM AUTHOR]

Vulvar cancers, which constitute 5% of all gynecologic cancers, are the fourth most common female genital cancers, preceded by uterine, ovarian and cervical cancers. The treatment methods employed for vulvar cancers have changed over the years, with previously applied radical surgical approaches, such as en bloc resection, being gradually suspended in favor of treatment approaches that require dissection of less tissue. While the removal of less tissue, which today's approaches have focused on, prevents morbidity, this method seems to result in higher risks of recurrence. It is therefore important that the balance between preventing the recurrence of the disease and forefending against postoperative complications and vulvar deformity be properly understood. As a working assumption, if patients with vulvar cancer are diagnosed at an early stage, properly evaluated and administered appropriate treatment, the most positive results can be obtained. This paper aims to highlight this assumption and demonstrate, through the provision of actual data, how to plan the treatment approach for patients who are diagnosed early. Statements extracted from the National Comprehensive Cancer Network (NCCN) Guidelines Version 1.2016 Sub-Committees on vulvar squamous cell carcinoma and articles by the European Society of Gynaecological Oncology (ESGO) regarding Vulvar Cancer Recommendations were used to obtain updated information.

Background: Lymph node metastases represent the most important negative prognostic predictor in vulvar carcinoma. Therefore, an accurate preoperative assessment of suspicious lymph nodes would be fundamental for a personalized therapy. The aim of this article was to assess the reliability of ultrasound‐guided fine‐needle aspiration cytology (FNAC) in the preoperative assessment of nodal metastatic disease in 43 patients with vulvar cancer. Methods: In total, 43 FNAC specimens of clinicoradiologically suspicious lymph nodes with corresponding nodal resection specimens were collected from 2016 to 2018 at Catholic University Hospital in Rome. Cytohistologic correlation was performed. Patients were treated with wide local excision of the vulvar mass followed by bilateral inguinofemoral lymphadenectomy and radiotherapy if the tumor involved a lymph node or the vulvar margins. Results: Cytologic examination agreed with histology in 37 of 43 cases (86.04%). The authors observed a positive FNAC result in 14 of 20 histologically confirmed metastatic lymph nodes, 6 false‐negative cases, and no false‐positive results. The sensitivity and specificity of cytological examination were 76.92% and 100%, respectively. All patients with FNAC‐positive results showed metastatic disease in other surgically resected inguinofemoral nodes. Eleven of 29 patients (37.9%) with FNAC‐negative results also showed metastatic disease in subsequent lymphadenectomy specimens, but the extent of metastases was always <1 cm (range, 0.1‐0.6 cm). Conclusions: FNAC of suspicious lymph nodes represents a useful tool in the management of patients with vulvar cancer. A positive result enables the surgeon to immediately perform a bilateral inguinofemoral lymphadenectomy thus avoiding an unnecessary sentinel lymph node sampling. Finally, FNAC can also predict the presence and extent of metastatic disease in other surgically resected inguinofemoral lymph nodes. Fine‐needle aspiration cytology of suspicious lymph nodes represents a useful tool in the management of patients with vulvar cancer, enabling the surgeon to perform a bilateral inguinofemoral lymphadenectomy immediately, thus avoiding an unnecessary sentinel lymph node sampling.

The objective of this study was to study the risk factors, management protocols, and the outcome of vulvar cancer cases over a period of 2 years in a tertiary care hospital. This is a case series of early-stage vulvar cancer in the Department of Surgical Oncology in BL Kapur Superspeciality Hospital from Jan 2016 to date. Five patients with histologically proven diagnosis of early-stage vulvar cancer were included. The mean age for the diagnosis of vulvar cancer was 58 years and the peak incidence was seen in postmenopausal age group. All of the cases were squamous cell carcinomas in stage IB except one which was a basisquamous variant. All cases were treated primarily with surgery and vulvar flap reconstruction. Adjuvant therapy was not given in any case. Cases were followed from 6 months to date, and no recurrence noted. The limitations of the study were rarity of disease and less number of cases. As all the cases in our study were in early stage of disease (stages I and II), surgical treatment in the form of modified radical vulvectomy with B/L inguinofemoral lymph node dissection and oncoplastic procedure was the treatment modality chosen for all the patients.

Purpose: To evaluate the effect of a collagen-fibrin sealant patch (TachoSil®) in preventing postoperative complications after inguinofemoral lymphadenectomy for vulvar cancer.Methods: Double-blind randomized-controlled trial on consecutive patients undergoing bilateral inguinofemoral lymphadenectomy for vulvar cancer. Intraoperatively, inguinofemoral areas were randomized: one was treated with TachoSil®, while the contralateral had standard closure without collagen-fibrin sealant patch. Surgical outcomes, amount of drainage volume, duration of drain placement, and any postoperative complication (vulvar wound dehiscence, inguinal wound dehiscence, cellulitis, lymphangitis, lymphoceles, and hematoma) were recorded. Leg measurements were taken preoperatively and during postoperative follow-up until 6 months to evaluate lymphedema.Results: A total of 19 patients were enrolled and 38 inguinofemoral dissections were performed. There was no significant difference between the investigational and control arm in the amount of drainage volume (p = 0.976), and duration of drain placement (p = 0.793). The postoperative complications, excluding lymphedema, were 10/19 (53%) in investigational arm and 9/19 (47%) in control arm (p = 0.74). At the end of follow-up, the prevalence of grade 1 lymphedema was 44.4% and 50% in investigational and control arm, respectively (p = 0.744); grade 2 and 3 lymphedema had a prevalence of 33.3% in both arms (p = 1).Conclusion: Application of TachoSil® does not seem to improve postoperative lymphorrhagia nor to reduce the incidence of postoperative complications in patients undergoing inguinofemoral lymphadenectomy for vulvar cancer. Considering this point, it would be useful to identify additional strategies in inguinofemoral dissection for the prevention of these complications. [ABSTRACT FROM AUTHOR]

Objective: Inguinofemoral lymphadenectomy (IFL) is included in the standard surgical management of early-stage vulval cancer (VC) but is often accompanied by surgical complications. Efforts have been made to limit the postoperative morbidity by adopting more conservative IFL techniques without compromising the surgical outcomes. Saphenous vein (SV) preservation during IFL for VC appears to reduce the incidence of postoperative complications including lymphedema. To ascertain the efficacy of SV preservation, we aimed to revisit the impact of SV preservation on short-term per groin complications by updating on a previous meta-analysis to further guide current clinical practice. Methods: A systematic literature review was conducted to identify studies that reported postoperative complications following IFL with SV preservation and controls (SV ligation during IFL) in VC patients. We included articles in English language and avoided date restrictions. Direct-comparison meta-analysis was performed between the use of SV preservation and SV ligation for the short-term outcomes of lymphedema, cellulitis, and wound dehiscence/breakdown. Fixed- and random-effects models were fitted to calculate the odds ratios (ORs) and 95% confidence intervals (CIs). Results: Five studies were included in the final analysis. Direct-comparison per-groin meta-analysis between SV preservation and SV ligation significantly decreased the odds for developing lymphedema (OR, 0.363; 95% CI, 0.228–0.578; P < 0.001), cellulitis (OR, 0.481; 95% CI, 0.28–0.825; P = 0.008), and wound dehiscence/breakdown (OR, 0.296; 95% CI, 0.191–0.458; P < 0.001). When SV sparing was clearly the sole intervention, lymphedema was the only complication in which the positive effect of SV sparing is exerted (OR, 0.28; 95% CI, 0.149–0.526; P < 0.001). Conclusions: This per groin meta-analysis updates on the current evidence suggesting the SV sparing improves postoperative outcomes following IFL in VC patients. Where sentinel biopsy is not indicated, this risk-reducing strategy should be considered in selected VC patients undergoing IFL until a multicenter randomized controlled trial becomes available.

Objective: Sentinel lymph node biopsy has been widely adopted in the surgical management of women with early-stage vulvar cancer, but many patients require inguinofemoral lymphadenectomy (IFL). Following IFL, many surgeons drain the groin to prevent lymphocyst formation despite a lack of evidence to support this practice. Our objective was to investigate whether groin drains after IFL are associated with reduced postoperative morbidity in women undergoing surgery for vulvar cancer. Methods: A retrospective cohort study of women diagnosed as having primary vulvar cancer who underwent vulvectomy/radical local excision and unilateral or bilateral IFL was conducted. Cases were ascertained from the weekly outcome reports of a statewide tertiary gynecologic oncology tumor board. Data including postoperative outcomes were abstracted from medical records. Patients were stratified into 1 of 2 groups according to whether a groin drain had been used. Results: Seventy-one patients were included. Inguinal drains were used in 48 patients (67.6%) and 23 patients (32.4%) did not have their groin wound(s) drained. The most common postoperative complications recorded were wound infection (59.2%), groin lymphocyst (32.4%), and cellulitis (25.4%). The mean length of hospital admission was 11.5 days (2-40 days). Compared with patients in whom inguinal drains were placed, those in the "no drain" group had a significantly lower incidence of postoperative groin cellulitis (8.7% vs 25.4% P = 0.039). No significant differences were observed between patients in the "drain" and "no drain" groups in lymphocyst formation, wound infection, return to the operating room, duration of hospital stay, readmission post-discharge, and lower-limb lymphedema. Conclusions: In this study of patients undergoing inguinofemoral dissection for primary vulvar cancer, postoperative cellulitis occurred less frequently in patients without an inguinal drain. The incidence of other postoperative complications was no different whether or not a groin drain was used. Prospective studies may be warranted. [ABSTRACT FROM AUTHOR]

Objective Inguinofemoral lymphadenectomy for patients with vulvar squamous cell carcinoma is associated with a high incidence of postoperative wound complications, which may be influenced by inguinal drain management. The aim of this nationwide prospective study (MAMBO: Morbidity And Measurement of the BOdy) was to assess the feasibility and the incidence of complications after volume-controlled versus short drainage. Methods The MAMBO study consisted of two observational studies in all eight oncology centers in the Netherlands, conducted between 2012 and 2016. In the first study, the drain was removed when the production was < 30 ml/24 h, except in the first 48 h, and after a maximum of 28 days (MAMBO-IA). In the second study, the drain was removed five days postoperatively regardless of production (MAMBO-IB). We assessed the complications within eight weeks after surgery using logistic regression to compare the incidence of one or more complications between the two drainage protocols, adjusting for possible confounders. Results We included 77 patients (139 groins) for volume-controlled drainage and 64 patients (112 groins) for short drainage. Volume-controlled drainage was associated with significant less lymphocele formation. Moreover, we found no difference in wound infection or primary wound breakdown. The estimated incidence of one or more complications was 46% per groin after volume-controlled drainage versus 75% after short drainage, (RD 29% (95% CI 8, 49) p = 0.006). Conclusions This prospective study shows that volume-controlled drainage is associated with significantly less complications compared to short drainage. We therefore recommend volume-controlled drainage after inguinofemoral lymphadenectomy in patients with vulvar squamous cell carcinoma. [ABSTRACT FROM AUTHOR]

Introduction: Inguinofemoral lymphadenectomy (IFL) is performed in the treatment for vulvar cancer. One or more complications after IFL is reported in up to 85% of the patients. This review presents an overview of surgical techniques and peri- and post-operative care that has been studied in order to reduce the morbidity associated with IFL in vulvar cancer patients. Areas covered: Current knowledge on post-operative complications after different surgical techniques and peri- and post-operative protocols were discussed. A systematic literature review was conducted using MEDLINE, EMBASE and the Cochrane library on 20 February 2017. In order to be eligible for inclusion, studies must report the associated post-operative morbidity per surgical technique, or peri- or post-operative care given after IFL in vulvar cancer patients. Expert commentary: After the implementation of several new surgical techniques, the morbidity after IFL decreased but remains high and clinically meaningful. More research is needed on surgical techniques and peri-or post-operative care to further reduce the complication rates after IFL in vulvar cancer patients. [ABSTRACT FROM AUTHOR]

Background/aim: The expression of the cyclin-dependent kinase inhibitor p16 correlates with the presence of human papillomavirus. The purpose of this investigation was to assess the prognostic relevance of p16 expression in patients with vulvar squamous cell carcinoma (VSCC) treated with radical surgery followed by adjuvant (chemo) radiation in selected cases., Patients and Methods: Seventy-eight patients were analyzed retrospectively., Results: Positive p16 immunostaining was detected in 19 (24.4%) patients. Five-year disease-free survival (DFS) and 5-year overall survival (OS) were better in p16-positive compared to p16-negative patients (83.9% versus 37.3% p=0.002 and 91.7% versus 57.6%, p=0.003, respectively). p16 expression retained prognostic relevance at multivariate analysis for both DFS and OS., Conclusion: p16 expression was detected in 24.4% of patients with VSCC and was found to be an independent prognostic variable for both DFS and OS., (Copyright © 2023 International Institute of Anticancer Research (Dr. George J.

Objective: The objective of this study was to study the risk factors, management protocols, and the outcome of vulvar cancer cases over a period of 10 years in a tertiary care hospital.Methodology: It is a retrospective cohort study. The hospital records of 41 patients with histologically proven vulvar cancer were studied from the Department of Obstetrics and Gynaecology and the Department of Radiotherapy (RT). The presence of risk factors, stage of disease, treatment modalities used, and disease outcomes in terms of survival were studied. The data collected were analyzed and compared with the published literature.Results: The mean age for the diagnosis of vulvar cancer was 52 years and the peak incidence was seen in the age group of 50-70 years. Incidence was significantly more in multiparous (P = 0.001) and postmenopausal women (P = 0.007). An average of 4.1 cases were seen per year. Nearly, 97.56% of the cases were squamous cell carcinomas. Twenty cases belonged to the early stage of the disease (Stage I and II) whereas 21 cases had advanced disease (Stage III and IV). Nearly, 48.78% of the cases were primarily treated with surgery, 26.83% with RT, 7.3% with chemotherapy, and 17.07% with combined chemoradiation. Seventy-eight percent of the surgically treated cases had a mean survival of 5 years. Mean survival of 1 year was recorded in advanced disease cases. Limitation of the study was poor follow-up after treatment.Conclusion: Incidence of vulvar cancer is significantly high in multiparous and postmenopausal women. Conservative surgical treatment is the best option in the early stage of the disease (Stage I and II) and gives high survival rates whereas advanced disease treated with chemoradiation has a poor survival.

Objectives Treatment of groin metastasis in vulvar squamous cell carcinoma (VSCC) patients consists of surgery, often combined with (chemo)radiotherapy, and is associated with significant morbidity. Our aim was to compare the risk of groin recurrence and morbidity in patients with lymph node positive VSCC after standard full inguinofemoral lymphadenectomy (IFL) versus less radical debulking of clinically involved lymph nodes or removal of sentinel nodes only followed by radiotherapy. Methods A retrospective cohort study of 68 patients with primary VSCC and proven lymph node metastasis to the groin(s) was conducted. Patients were divided into three subgroups by type of initial groin surgery (84 groins): sentinel node (SN), IFL, and debulking of clinically involved nodes. Most patients (82%) received adjuvant radiotherapy. Overall survival was analyzed using time dependent cox regression. Analysis of morbidity and groin recurrence-free time was performed per groin with the generalized estimating equation model and Kaplan Meier method. Results There was no significant difference in the risk of developing a groin recurrence (SN 25%, debulking 16%, IFL 13%, p = 0.495). Despite the fact that more patients received radiotherapy after debulking (90% vs 67%), the complication rate was significantly lower (p = 0.003) compared to IFL, especially regarding lymphocysts and lymphedema (p = 0.032 and p = 0.002 respectively). Conclusions The risk of groin recurrence was similar in all treatment groups. Debulking of clinically involved lymph nodes was related to a significant lower risk of complications compared to IFL. These findings support that the preferred treatment of patients with clinically involved lymph nodes is debulking followed by radiotherapy. [ABSTRACT FROM AUTHOR]

Background: Vulval cancer causes 3–5% of all gynaecological malignancies and requires surgical removal and inguinofemoral lymphadenectomy (IFL). Complications affect > 50% of patients, including groin wound infection, lymphoedema and cellulitis. A sentinel lymph node (SLN) is the first groin node with the highest probability of malignancy. SLN biopsy would be useful if it could accurately identify patients in whom cancer has spread to the groin, without removing all groin nodes. SLNs can be identified by isosulfan blue dye and/or technetium-99 (99mTc) radioactive tracer during lymphoscintigraphy. The blue dye/99mTc procedure only detects SLN, not metastases – this requires histological examination, which can include ultrastaging and staining with conventional haematoxylin and eosin (H&E) or immunohistochemistry. Objectives: To determine the test accuracy and cost-effectiveness of the SLN biopsy with 99mTc and/or blue dye compared with IFL or clinical follow-up for test negatives in vulval cancer, through systematic reviews and economic evaluation. Data sources: Standard medical databases, including MEDLINE, EMBASE, Science Citation Index and The Cochrane Library, medical search gateways, reference lists of review articles and included studies were searched to January 2011. Methods: For accuracy and effectiveness, standard methods were used and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Searches were to January 2011, with no language restrictions. Meta-analyses were carried out with Meta-Disc version 1.4 (Javier Zamora, Madrid, Spain) for accuracy; none was appropriate for effectiveness. The economic evaluation from a NHS perspective used a decision-tree model in DATA TreeAge Pro Healthcare 2001 (TreeAge Software, Inc., Williamstown, MA, USA). Six options (blue dye with H&E, blue dye with ultrastaging, 99mTc with H&E, 99mTc with ultrastaging, blue dye/99mTc with H&E, blue dye/99mTc with ultrastaging) were compared with IFL. Deterministic and probabilistic sensitivity analyses were conducted. Results: For accuracy, of the 26 included studies, most evaluated 99mTc/blue dye combined. Four studies had clinical follow-up only for test negatives and five had clinical follow-up for all and IFL for test negatives. Numbers with no SLN found were difficult to distinguish from those with negative SLN biopsies. The largest group of 11 studies using 99mTc/blue dye, ultrastaging and immunohistochemistry had a pooled sensitivity of 95.6% [95% confidence interval (CI) 91.5% to 98.1%] and a specificity of 100% (95% CI 99.0% to 100%). Mean SLN detection rates were 94.6% for 99mTc, 68.7% for blue dye and 97.7% for both. One study measured global health status quality of life (QoL) and found no difference between SLN biopsy and IFL. One patient preference evaluation showed that 66% preferred IFL rather than a 5% false-negative rate from SLN biopsy. For effectiveness, of 14,038 references, one randomised controlled trial, three case–control studies and 13 case series were found. Approximately 50% died from vulval cancer and 50% from other causes during follow-ups. Recurrences were in the ratio of approximately 4 : 2 : 1 vulval, groin and distant, with more recurrences in node-positive patients. No studies reported QoL. For cost per death averted, IFL was less costly and more effective than strategies using SLN biopsy. For morbidity-free survival and long-term morbidity-free survival, 99mTc with ultrastaging was most cost-effective. Strategies with blue dye only and H&E only were never cost-effective. The incremental cost-effectiveness ratio for 99mTc with ultrastaging compared with IFL was £4300 per case of morbidity-free survival and £7100 per long-term morbidity-free survival. Limitations: The main limitations of this study include the lack of good-quality evidence on accuracy, effectiveness and QoL. A large project such as this takes time to publish, so the most recent studies are not included. Conclusions: A sensitive and specific combined metastatic SLN detection test and information on generic QoL in vulval cancer is urgently required.

Abstract: Vulval cancer is rare accounting for 0.7% of all new cases of female cancers and represents about 4 % of all gynaecological malignancies. Squamous cell carcinoma is the most frequent histological subtype of cancer of the vulva followed by malignant melanoma. Although predominantly considered as a disease of postmenopausal women, there has been a significant increase in rates of vulval cancer in younger women possibly due to increasing incidence of premalignant lesions of vulva caused by human papilloma virus infection. Management of vulval cancer has evolved into an individualized multidisciplinary approach, and patients should be referred centrally to a gynaecological cancer centre where all relevant expertise is available. Usual treatment of vulval cancer includes surgical excision of primary lesion and lymph node assessment by sentinel node dissection or inguinofemoral lymphadenectomy. Radiotherapy can be added to the above treatment if there is high risk of disease recurrence or to control residual disease when repeat surgery is not feasible. The mainstay of treatment is surgery and the disease itself as well as treatment carries long-term physical and psychological sequelae. Although survival rates are high for those with negative groin nodes, the morbidity associated with standard radical techniques has prompted innovation for less radical approach such as sentinel node detection. This review highlights the current understanding of the aetiology, pathophysiology and management of vulval cancer. [Copyright &y& Elsevier]

The objective of the study is to determine the risk factors for groin recurrence (GR) in patients with primary vulvar squamous cell carcinoma (SCC) after inguinofemoral lymphadenectomy (IFL) without lymph node metastases and/or adjuvant chemoradiotherapy.The study is a multicenter retrospective review of clinical and histopathological data of patients with lymph node-negative vulvar SCC who underwent an IFL. Patients with and without GRs were compared to identify risk factors.In 134 patients, 252 groins were eligible for the analyses—16 patients underwent ipsilateral IFL and 118 patients underwent bilateral IFL. Groin recurrences occurred in 4 (1.6%) of the 252 dissected groins. Besides, 1 patient who underwent ipsilateral IFL had a recurrence in the nonoperated contralateral groin; this groin was left out of analysis. The median number of dissected nodes per groin was 9.8 (range, 1-38) in all patients and 6.5 (range, 5-8) in patients with GR. Multivariate analyses showed that GR was related to poor differentiation (P = 0.04), and node count less than 9 (P = 0.04), no association with age, tumor localization, tumor diameter, focality, invasion depth, or stage was found. Nineteen patients with both low node count and poor differentiation had 19% GRs. Survival analyses showed less favorable survival in patients with poor differentiation.The overall risk of developing GR after negative IFL in patients with vulvar SCC is low (1.6% per groin) but significantly higher in patients with tumors with a poor differentiation and lymph node count less than 9 at IFL. A large well-designed prospective study is needed to evaluate closer surveillance in patients at risk. [ABSTRACT FROM AUTHOR]

Abstract: Objectives: To investigate the occurrence and severity of lymphoedema of the lower extremities (LLE), quality of life (QoL), and urinary and sexual dysfunction in women with vulvar cancer submitted to surgical treatment. Study design: Twenty-eight patients with vulvar cancer submitted to vulvectomy and inguinofemoral lymphadenectomy and 28 healthy, age-matched women (control group) were evaluated. The occurrence and severity of LLE were determined by Miller''s Clinical Evaluation. QoL, urinary function and sexual function were assessed by the EORTC QLQ-C30, SF-ICIQ and FSFI questionnaires, respectively. The differences between groups and correlations were assessed using Student''s t-test, Chi-squared test, Mann–Whitney U-test and Spearman''s rho test. Results: The groups were similar in terms of marital status, educational status, menopausal status, hormone therapy and height. The occurrence and severity of LLE were higher in women with vulvar cancer compared with the control group (p <0.001 and p =0.003, respectively). A significant association was found between the severity of LLE and advanced age (p =0.04), and the severity of LLE and higher body mass index (BMI; p =0.04) in patients with vulvar cancer. In the patients with vulvar cancer, there was a significant correlation between the severity of LLE and worse QoL in the following domains: physical, cognitive, emotional, social, fatigue, pain, sleep and financial questions (p <0.05). There was no difference in urinary function between the two groups (p =0.113). Age and number of deliveries were the only variables associated with the occurrence of urinary incontinence (p =0.01). Urinary incontinence was present in women with a mean age of 74.9±4.6 years and a mean of 7.3±1.3 normal deliveries. There was no difference between the groups in terms of the sexual function. Multivariate analysis showed an association between sexual function and age (p =0.01), and sexual function and being in a stable relationship (p =0.02). Conclusion: Patients submitted to vulvectomy or inguinofemoral lymphadenectomy for vulvar cancer are at higher risk of developing LLE compared with healthy, age-matched women. This has a negative effect on QoL, but does not interfere with urinary or sexual function. [Copyright &y& Elsevier]
