Preoperative radiation therapy for locally advanced vulvar cancer

Surgical Margins After Neoadjuvant Radiation for Locally Advanced Vulvar Carcinoma: What is an Adequate Margin?

OBJECTIVE

We aim to explore whether the surgical tumor free margin is important for overall survival (OS) and local control in patients who undergo neoadjuvant radiation (RT) for vulvar cancer.

METHODS

A retrospective review from 2004 to 2021 of patients who underwent RT followed by surgical resection was performed. Patients were categorized into groups based on margin status (no residual disease, >8 mm, close margins defined as 1 to 7 mm, or positive). Local control and OS were analyzed using the Kaplan-Meier with log rank test. Multivariate analysis was performed with cox hazards model.

RESULTS

Eighty-three patients were included. A complete pathologic response (pCR) was found in 56% (n=46) of patients. The median follow-up time was 35 months (range: 4 to 216). The median OS for the entire cohort was 46 months (95% CI: 32.3-59.7). Having a pCR improved both OS and disease-free survival (DFS) compared with residual disease by 81 and 91 months, respectively (P<0.001). In the 2 patients with a margin >8 mm, there was no statistical difference in survival between those with close margins (46 vs. 25 mo, P=0.485). Factors that significantly impacted both OS and DFS were depth of invasion (DOI) and LVSI. On multivariate analysis of those with residual disease, there was no difference in OS or DFS by margin status but having a DOI >9 mm showed decreased OS (HR: 3.654; 95% CI: 1.317-10.135).

CONCLUSIONS

In this cohort, response to RT, not margin status drives survival and recurrence. Given residual disease, the optimal margin is not clear, as there were only 2 patients with >8 mm margins. A close or positive margin had no impact on OS or local recurrence. A DOI >9 mm significantly impacts both OS and local recurrence even when accounting for other factors.

The Therapy of Vulvar Carcinoma-Evaluation of Surgical Options in a Retrospective Monocentric Study

(1) Background: Surgical-oncological treatment methods are continuously put to the test in times of evidence-based medicine-notably, a constant reevaluation remains key, especially for tumor entities with increasing incidence such as vulvar carcinoma. (2) Methods: In order to determine the postoperative clinical course of different methods of vulvar excision (vulvectomy, hemivulvectomy) as well as inguinal lymph node removal (lymphadenectomy, sentinel lymph node biopsy) with regard to postoperative wound-healingprocess, perioperative hemorrhage, and re-resection rates, we retrospectively analyzed surgical, morphological and laboratory data of 76 patients with a pathological diagnosed vulvar cancer. (3) Results: Analysis of our data from a single center revealed a comparable perioperative clinical course regardless of the chosen method of vulvar excision and inguinal lymph node removal. (4) Conclusions: Thus, our results emphasize the current multimodality in surgical therapy of vulvar carcinoma, in which consideration of known prognostic factors together with the individual patient's clinical situation allow guideline-based therapy aimed at maximizing surgical safety.

Factors associated with vulvar cancer from 2005 to 2021 in Togo, sub-Saharan Africa

BACKGROUND

vulvar cancer, once predominantly diagnosed in older women, is increasingly being diagnosed in younger individuals, due to Human Papillomavirus (HPV) infection. Our study aimed to describe the epidemiological and histopathological aspects of vulvar cancer in Togo and its associated factors.

METHODS

This was a cross-sectional study, conducted on vulvar cancer cases histologically diagnosed at the Pathological Laboratory of Lomé over a period of 17-years (2005-2021). Parameters investigated included age, occupation, risk factors, sample nature, macroscopic tumor aspects, histological types, therapeutic intervenions, and prognostic outcomes.

RESULTS

A total of 32 cases of vulvar cancer were collected, yieding an annual frequency of 1.88 cases. The average age of the patients was 48±14.12 years with extremes of 27 years and 82 years. Housewives accounted for the largest proportion of cases (37.5%). Among the 32 cases, 27 had identifiable risk factors, with HPV infection being the most prevalentr (33.3%). The ulcero-budding aspect was most frequently observed, and squamous cell carcinoma was the most common histological type, with the majority being well differentiated (89.3%). Statistically significant associations were found between risk factors and histological types, risk factors and degrees of differentiation, as well as between histological types and good differentiation of vulvar cancers. The 3-year survival was estimated at 78.13%.

CONCLUSION

The incidence of vulvar cancer is increasing in Togo, particularly among young, primarily due to HPV infection.

Vulvar Cancer: 2021 Revised FIGO Staging System and the Role of Imaging

Vulvar cancer is a rare gynecological malignancy. It constitutes 5-8% of all gynecologic neoplasms, and squamous cell carcinoma is the most common variant. This article aims to review the etiopathogenesis revised 2021 International Federation of Gynecology and Obstetrics (FIGO) classification and emphasize imaging in the staging of vulvar cancer. The staging has been regulated by FIGO since 1969 and is subjected to multiple revisions. Previous 2009 FIGO classification is limited by the prognostic capability, which prompted the 2021 revisions and issue of a new FIGO classification. Although vulvar cancer can be visualized clinically, imaging plays a crucial role in the staging of the tumor, assessing the tumor extent, and planning the management. In addition, sentinel lymph node biopsy facilitates the histopathological staging of the draining lymph node, thus enabling early detection of tumor metastases and better survival rates.

Definitive chemoradiation or radiation therapy alone for the management of vulvar cancer

Vulvar cancer is rare, and unresectable disease provides a therapeutic conundrum. Although definitive surgery remains the mainstay for curative treatment of vulvar cancer, a minority of patients present with advanced disease for which surgical resection would be extraordinarily morbid. Pre-operative and definitive radiation with radiosensitizing systemic therapy allows such patients an opportunity for cure. In this review, we explore the origins of pre-operative radiation, current treatment standards for pre-operative and definitive chemoradiation, and future directions.

Management of Advanced Squamous Cell Carcinoma of the Vulva

Simple Summary

Vulvar cancer is a rare gynaecological malignancy that has an increasing incidence, particularly in younger women. Early vulvar cancer can be treated and cured with surgical excision. Approximately 30% of women present with advanced disease, which requires treatment either with mutilating surgery or a combination of chemotherapy and radiotherapy, which is an effective treatment but has many side effects. Current research is focused on new less morbid approaches to treatment, in which drugs that target various steps on the biological pathway from pre-cancer to cancer are used, with the aim of preventing the growth of vulvar cancers. This review is an update of the current management of women with advanced vulvar cancer.

Abstract

Vulvar cancer is a rare gynaecological malignancy, accounting for 2–5% of cancers of the female genital tract. Squamous cell carcinoma is the most frequently occurring subtype and, historically, has been a disease of older post-menopausal women, occurring with a background of lichen sclerosus and other epithelial conditions of the vulvar skin that may be associated with well-differentiated vulvar intra-epithelial neoplasia (dVIN). An increase in human papillomavirus (HPV) infections worldwide has led to an increase in vulvar squamous carcinomas in younger women, resulting from HPV-associated high-grade vulvar squamous intra-epithelial lesions (vHSIL). Surgical resection is the gold standard for the treatment of vulvar cancer. However, as approximately 30% of patients present with locally advanced disease, which is either irresectable or will require radical surgical resection, possibly with a stoma, there has been a need to investigate alternative forms of treatment such as chemoradiation and targeted therapies, which may minimise the psychosexual morbidity of radical surgery. This review aims to provide an update on management strategies for women with advanced vulvar cancer. It is hoped that investigation of the molecular biologies of the two different pathways to vulvar squamous cell carcinoma (HPV-associated and non-HPV-associated) will lead to the development of targeted therapeutic agents.

Cancer of the vulva: 2021 update

Vulvar cancer is an uncommon gynecological malignancy primarily affecting postmenopausal women. There is no specific screening and the most effective strategy to reduce vulvar cancer incidence is the opportune treatment of predisposing and preneoplastic lesions associated with its development. While vulvar cancer may be asymptomatic, most women present with vulvar pruritus or pain, or have noticed a lump or ulcer. Therefore, any suspicious vulvar lesion should be biopsied to exclude invasion. Once established, the most common subtype is squamous cell carcinoma. Treatment of vulvar cancer depends primarily on histology and surgical staging. Treatment is predominantly surgical, particularly for squamous cell carcinoma, although concurrent chemoradiation is an effective alternative, particularly for advanced tumors. Management should be individualized and carried out by a multidisciplinary team in a cancer center experienced in the treatment of these tumors.

A useful update for trainees and specialists regarding the diagnosis, staging, treatment, and some controversies in the management of vulvar neoplasms.

Locally advanced squamous cell carcinoma of the vulva: A challenging question for gynecologic oncologists

Squamous cell carcinoma of the vulva is a rare female malignancy, with an incidence increasing with age. Unfortunately, one third of the patients are diagnosed with locally advanced disease, which constitutes a clinical challenge for the clinicians who treat these patients. The main challenges are represented by: 1. The primary site of the disease, which can be proximal to anatomical structures like the anal canal posteriorly, or the urethra and the bladder anteriorly, that in some circumstances cannot be spared without a bowel and/or urinary stoma; 2. The locoregional nodes that can be involved by the tumor, and they can be bulky, fixed or ulcerated; 3. The clinical condition of the patient, who may carry several comorbidities. Treatment modalities include radiation with or without chemotherapy, and surgery. In order to preserve the bowel and the urinary function without a permanent stoma, a personalized management with a multimodality approach is warranted. In this systematic review, we first clarify the different definitions of "locally advanced vulvar carcinoma". Secondly, we evaluated the different treatment modalities described in the literature, and the impact of the different treatment strategies on prognosis and on preservation of bowel/urinary function. Finally, we offer a possible algorithm that may help the clinicians in treating patients with these uncommon and challenging situations with a multidisciplinary approach.

Locally advanced vulva cancer: A single centre review of anovulvectomy and a systematic review of surgical, chemotherapy and radiotherapy alternatives. Is an international collaborative RCT destined for the "too difficult to do" box?

INTRODUCTION

Treatment of locally advanced vulva cancer (LAVC) remains challenging. Due to the lack of randomised trials many questions regarding the indications for different treatment options and their efficacy remain unanswered.

METHODS

In this retrospective study we provide the largest published series of LAVC patients treated with anovulvectomy, reporting oncological outcomes and morbidity. Additionally, a systematic literature review was performed for all treatment options 1946-2015.

RESULTS

In our case series, 57/70 (81%) patients were treated in the primary setting with anovulvectomy and 13 patients underwent anovulvectomy for recurrent disease. The median overall survival (OS) was 69months (1-336) with disease specific survival of 159months (1-336). Following anovulvectomy for primary disease, time to progression and OS were significantly higher in node negative disease (10 vs. 96months; 19 vs. 121months, p<0.0001). Post-surgical complications were observed in 36 (51.4%), the majority of which were Grade I/II infections. There was one peri-operative death. Review of the literature showed that chemotherapy, radiotherapy or combination treatments are alternatives to surgery. Evidence relating to all of these consisted mostly of small retrospective series, which varied considerably in terms of patient characteristics and treatment schedules. Significant patient and treatment heterogeneity prevented meta-analysis with significant biases in these studies. It was unclear if survival or morbidity was better in any one group with a lack of data reporting complications, quality of life, and long term follow-up. However, results for chemoradiation are encouraging enough to warrant further investigation.

CONCLUSIONS

There remains inadequate evidence to identify an optimal treatment for LAVC. However, there is sufficient evidence to support a trial of anovulvectomy versus chemoradiation. Discussions and consensus would be needed to determine trial criteria including the primary outcome measure. Neoadjuvant chemotherapy or radiotherapy alone may be best reserved for the palliative setting or metastatic disease.

Treatment of Inoperable Vulvar Cancer: Where We Come From and Where Are We Going

Abstract

Vulvar cancer is a rare disease affecting elderly women that is commonly treated with surgery, radiation, and chemotherapy. When tumors compromise the urethra and the anus, or when it is in the groin lymph nodes, radiotherapy, chemotherapy, or both are necessary after surgery.

The treatment of locally advanced vulvar cancer has suffered significant changes though the recent decades. So far, the best sequence of treatment is not known: surgery, chemotherapy, or radiotherapy. The radical surgeries usually need a long recovery term both in the region of the vulva and in the area of the groin lymph nodes. When it is performed, convalescence can delay other treatments, such as radiotherapy and chemotherapy. On the other hand, the use of radiotherapy and chemotherapy as a first step treatment can result in a complete elimination of the disease in at least 30% of the cases or substantial reduction of its size, allowing less extensive surgery. Therefore, the historical evolution of locally advanced vulvar cancer is reviewed.

Vulvar cancer: epidemiology, clinical presentation, and management options

EPIDEMIOLOGY

Vulvar cancer can be classified into two groups according to predisposing factors: the first type correlates with a HPV infection and occurs mostly in younger patients. The second group is not HPV associated and occurs often in elderly women without neoplastic epithelial disorders.

HISTOLOGY

Squamous cell carcinoma (SCC) is the most common malignant tumor of the vulva (95%).

CLINICAL FEATURES

Pruritus is the most common and long-lasting reported symptom of vulvar cancer, followed by vulvar bleeding, discharge, dysuria, and pain.

THERAPY

The gold standard for even a small invasive carcinoma of the vulva was historically radical vulvectomy with removal of the tumor with a wide margin followed by an en bloc resection of the inguinal and often the pelvic lymph nodes. Currently, a more individualized and less radical treatment is suggested: a radical wide local excision is possible in the case of localized lesions (T1). A sentinel lymph node (SLN) biopsy may be performed to reduce wound complications and lymphedema.

PROGNOSIS

The survival of patients with vulvar cancer is good when convenient therapy is arranged quickly after initial diagnosis. Inguinal and/or femoral node involvement is the most significant prognostic factor for survival.

Prognosis of vulval cancer with lymph node status and size of primary lesion: A survival study

Introduction:

Squamous cell cancer of the vulva is a rare disease with an annual incidence of two to three per 100,000 women. Lymph node metastasis is the most important prognostic factor for the recurrence and survival in vulval carcinoma.

Materials and Methods:

It is a retrospective study of 18 cases, operated in our institute from 2006 to 2009 and followed up till July, 2012. These patients were divided into two group of node positive and node negative and compared for recurrence and survival.

Result:

Ten patients had lymph node metastasis and eight had no lymph node metastasis. Recurrence rate was 40% and 12.5% in node positive and negative groups, respectively. Adjuvant radiation when given to node negative bulky tumor showed no recurrence compared to one out of two in the non-irradiated group. Survival was only 25% in node positive recurrent cases.

Conclusion:

Lymph node positivity added a great risk for future recurrence. Prophylactic radiation in node negative, bulky tumor is helpful.

Patterns of care for locally advanced vulvar cancer

OBJECTIVE

Patients with locally advanced vulvar carcinoma can be treated with primary surgery or neoadjuvant chemoradiation. Neoadjuvant treatment appears to be associated with decreased morbidity and acceptable long-term outcomes. We examined the patterns of care for women with locally advanced vulvar cancer.

STUDY DESIGN

Data from the Surveillance, Epidemiology, and End Results (SEER) database was used to examine women with stage III-IVA vulvar cancer treated from 1988 to 2008. Primary therapy was classified as surgery or radiation. Multivariable logistic regression models were developed to examine the use of primary radiotherapy.

RESULTS

We identified a total of 2292 women including 1757 who underwent primary surgery (76.7%) and 535 treated with primary radiation (23.3%). The use of primary radiation increased with time from 18.0% in 1988 to 30.1% in 2008. In a multivariable model, older women (odds ratio [OR], 1.33; 95% confidence interval [CI], 1.03-1.72), black women (OR, 1.59; 95% CI, 1.14-2.23), and patients with stage IVA tumors (OR, 2.23; 95% CI, 1.78-2.81) were more likely to receive primary radiation. Among women treated with primary radiotherapy, only 17.8% ultimately underwent surgical resection.

CONCLUSION

The use of primary radiation for locally advanced vulvar cancer is limited but has increased over time. Multiple patient and tumor factors influence use. The majority of patients with stage III-IVA vulvar cancer treated with primary radiation therapy did not undergo surgical resection.

Neoadjuvant chemoradiotherapy followed by surgery in locally advanced squamous cell carcinoma of the vulva

Alternative therapies have been sought to alleviate mutilation and morbidity associated with surgery for vulvar neoplasms. Our prime objective was to assess tumor absence in pathological vulvar and nodal specimens following neoadjuvant chemoradiotherapy in locally advanced vulvar neoplasms. Data were retrospectively collected from January 2001 to May 2009 from 22 patients treated with neoadjuvant therapy for locally advanced squamous cell carcinoma of the vulva. Neoadjuvant treatment consisted of inguino-pelvic radiotherapy (50 Gy) in association with chemotherapy when possible. Surgery occurred at intervals of between 5 to 8 weeks. The median age of patients at diagnosis was 74.1 years. All patients were primarily treated with radiotherapy and 15 received a concomitant chemotherapy. Additionally, all patients underwent radical vulvectomy and bilateral inguino-femoral lymphadenectomy. Tumor absence in the vulvar and nodal pathological specimens was achieved for 6 (27%) patients, while absence in the vulvar pathological specimens was only achieved for 10 (45.4%) patients. Postoperative follow-up revealed breakdown of groin wounds, vulvar wounds and chronic lymphedema in 3 (14.3%), 7 (31.8%) and 14 cases (63.6%), respectively. Within a median follow-up time of 2.3 years [interquartile range (IQR), 0.6-4.6], 12 (54.6%) patients experienced complete remission and 6 cases succumbed to metastatic evolution within a median of 2.2 years (IQR, 0.6-4.6), with 1 case also experiencing perineal recurrence. Median survival time, estimated using the Kaplan-Meier method, was 5.1 years (IQR, 1.0-6.8). We suggest that neoadjuvant chemoradiotherapy may represent a reliable and promising strategy in locally advanced squamous cell carcinoma of the vulva.

A phase II trial of radiation therapy and weekly cisplatin chemotherapy for the treatment of locally-advanced squamous cell carcinoma of the vulva: a gynecologic oncology group study

OBJECTIVES

To determine the efficacy and toxicity of radiation therapy and concurrent weekly cisplatin chemotherapy in achieving a complete clinical and pathologic response when used for the primary treatment of locally-advanced vulvar carcinoma.

METHODS

Patients with locally-advanced (T3 or T4 tumors not amenable to surgical resection via radical vulvectomy), previously untreated squamous cell carcinoma of the vulva were treated with radiation (1.8 Gy daily × 32 fractions=57.6 Gy) plus weekly cisplatin (40 mg/m(2)) followed by surgical resection of residual tumor (or biopsy to confirm complete clinical response). Management of the groin lymph nodes was standardized and was not a statistical endpoint. Primary endpoints were complete clinical and pathologic response rates of the primary vulvar tumor.

RESULTS

A planned interim analysis indicated sufficient activity to reopen the study to a second stage of accrual. Among 58 evaluable patients, there were 40 (69%) who completed study treatment. Reasons for prematurely discontinuing treatment included: patient refusal (N=4), toxicity (N=9), death (N=2), other (N=3). There were 37 patients with a complete clinical response (37/58; 64%). Among these women there were 34 who underwent surgical biopsy and 29 (78%) who also had a complete pathological response. Common adverse effects included leukopenia, pain, radiation dermatitis, pain, or metabolic changes.

CONCLUSIONS

This combination of radiation therapy plus weekly cisplatin successfully yielded high complete clinical and pathologic response rates with acceptable toxicity.

Chemoradiation for advanced primary vulval cancer

BACKGROUND

Vulval cancer is a rare gynaecological cancer. There is no standard approach for treating locally advanced primary vulval cancer (FIGO stage III and IV). Combined treatment modalities have been developed using radiotherapy, chemotherapy and surgery. The advantages and disadvantages of such treatment is not well evaluated.

OBJECTIVES

To evaluate the effectiveness and safety of neoadjuvant and primary chemoradiation for women with locally advanced primary vulval cancer compared to other primary modalities of treatment such as primary surgery or primary radiation.

SEARCH STRATEGY

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2009, Issue 3), Cochrane Gynaecological Cancer Group Trials Register, MEDLINE and EMBASE (to July 2009). We also searched registers of clinical trials, abstracts of scientific meetings, reference lists of included studies and contacted experts in the field.

SELECTION CRITERIA

Randomised controlled trials (RCTs) or non-randomised studies that included multivariate analyses of chemoradiation in women with locally advanced, primary squamous cell carcinoma of the vulva.

DATA COLLECTION AND ANALYSIS

Two review authors independently abstracted data and assessed risk of bias. An adjusted hazard ratio (HR) for overall survival was calculated for one non-randomised study and risk ratios (RRs) were used in an RCT to compare five-year death rates and adverse events in women who received neoadjuvant, primary chemoradiation or primary surgery. Adverse events were also reported more extensively in a further non-randomised study. All results were displayed in single study analyses.

MAIN RESULTS

One RCT and two non-randomised studies that allowed for multivariate analyses met the inclusion criteria and included a total of 141 women.One RCT found that neoadjuvant chemoradiation did not appear to offer longer survival compared to primary surgery in advanced vulval tumours (RR = 1.29, 95% confidence interval (CI) 0.87 to 1.91). There was also no statistically significant difference in survival between primary chemoradiation and primary surgery in a study that included 63 women (pooled adjusted HR= 1.09, 95% CI 0.37 to 3.17) and in another study that only included 12 eligible women and compared the same interventions (HR was non-informative when statistical adjustment was made).Adverse events were extensively reported in only one study, which found no statistically significant difference in risk of adverse events between primary chemoradiation and primary surgery due to the very small numbers in each group. In the RCT there was no observed statistically significant difference between neoadjuvant chemoradiation and primary surgery. Adverse events were not reported in the largest study of 63 women. Quality of life (QoL) was not reported in any of the included studies. All studies were at high risk of bias.

AUTHORS' CONCLUSIONS

Women with advanced vulval tumours showed no significant difference in overall survival or treatment-related adverse events when chemoradiation (primary or neoadjuvant) was compared with primary surgery.The retrospective studies had a high risk of bias as the entry criteria for primary chemoradiation was based on inoperability or tumour requiring exenteration.The radiochemotherapy regimens varied widely. There was no data on QoL.There is no standard terminology for 'operable and inoperable vulval cancer', and for 'primary and neoadjuvant chemoradiation'. Stratification according to unresectability of the primary tumour and/or lymph nodes is needed, for good quality comparison.

Cyberknife Radiosurgery for Squamous Cell Carcinoma of Vulva after Prior Pelvic Radiation Therapy

Limited options exist for patients experiencing a local recurrence of vulvar malignancies after surgery and pelvic radiation. These recurrences often are associated with cancer-related skin desquamation and poor clinical outcomes. A new radiotherapeutic treatment modality for the previously irradiated patient is cyberknife radiosurgery, which uses a linear accelerator mounted on an industrial robotic arm to allow non-coplanar radiation therapy delivery with sub-millimeter precision. This study describes the first reported use of cyberknife radiosurgery for the treatment of recurrent vulvar cancer in three women.

Comparison of outcome measures in patients with advanced squamous cell carcinoma of the vulva treated with surgery or primary chemoradiation

OBJECTIVE

To review outcome measures including overall survival (OS), progression free survival (PFS), and patterns of recurrence in patients with advanced vulvar cancer managed by primary surgery (PS) or primary chemoradiation (PCRT) as well as population characteristics for the two groups.

METHODS

Patients diagnosed with stage III and IV squamous cell carcinoma of the vulva from 1990 to 2006 were identified for retrospective analysis at a single institution. Charts were abstracted for clinical and pathologic findings, treatment modalities, complications, recurrence, and follow-up. Kaplan-Meier method was used to determine PFS and OS.

RESULTS

Sixty-three patients with stage III (n=47) and IV (n=16) carcinoma of the vulva were identified; 30 patients were treated with PS, and 33 patients had tumor that was unresectable by vulvectomy and underwent PCRT. Patients treated with PCRT were younger (61 vs. 72 years; p=0.09), had less metastasis to lymph nodes (54% vs. 83%, p=0.01), and larger tumors (6 vs. 3.5 cm, p=0.0001) compared to patients treated with PS. Despite these differences, OS for the PS and PCRT groups was 69% and 76% (NS), respectively, with median follow-up at 31 months. There were no differences in PFS or recurrence rates between the two groups. By multivariate analysis, age was the only significant predictor of OS or PFS.

CONCLUSIONS

Patients with advanced vulvar cancer that are managed with PS tend to be older patients that have smaller lesions but positive lymph nodes, whereas patients requiring PCRT are younger and have larger volume disease but fewer lymph node metastases. Despite these differences, patients treated with PS and PCRT have no differences in OS, PFS, or recurrence rates. Age is the most powerful predictor of survival when size, lymph node status, stage and treatment are accounted for.

Carcinoma of the vulva

The objective of this review is to summarize the published data about squamous carcinoma of the vulva and to identify promising areas for future investigation. Rather than the routine use of complete radical vulvectomy, a radical wide excision of the vulvar lesion to achieve at least a 1-cm gross margin appears sufficient to treat the primary lesion. A surgical assessment of the groin is required for all patients who have invasion greater than 1 mm. Ipsilateral groin node dissection can be performed through a separate incision. All the nodal tissue medial to the vessels and above the fascia should be removed. Sentinel node evaluation may be a significant step forward, but the false-negative rate is not well enough defined to consider this a standard. Patients with positive inguinal nodes at groin dissection should receive radiation therapy to the ipsilateral groin and hemipelvis. For those patients who have unresectable primary disease or if nodes are palpably suspicious, fixed, and/or ulcerated preoperatively, chemoradiation is the preferred option. Exenterative procedures may rarely be required. Chemotherapy for recurrent or metastatic disease has not been proven to be of value. Although survival rates are high for those with negative nodes, the morbidity associated with standard radical techniques has prompted innovation. Adequately powered trials aimed at further reducing morbidity without compromising survival are underway.

Cancer testis antigen expression in primary and recurrent vulvar cancer: association with prognostic factors

Cancer testis tumour associated antigens (C/T-TAAs) were investigated in several gynaecologic and non-gynaecologic neoplasms as possible prognostic markers and targets for immunotherapy. The objective of the present study was to evaluate C/T-TAA expression patterns and prognostic significance in patients affected by vulvar cancer. Melanoma antigen E (MAGE)-A1, MAGE-A4 and NY-ESO-1 expression was determined by immunohistochemistry in paraffin-embedded tissue specimens from 45 primary and 14 recurrent vulvar carcinomas treated with surgery. MAGE-A1, MAGE-A4 and NY-ESO-1 were expressed in 25 (42%), 38 (64%) and 40 (68%) of the 59 samples, respectively. MAGE-A4 was significantly more frequently expressed in tumours with lymph node metastases (p<0.002) and in recurrent tumours (p<0.02). NY-ESO-1 was more highly expressed by moderately or poorly differentiated tumours (p<0.01). This study demonstrates that vulvar cancer frequently expresses C/T-TAAs. Antigen expression correlates with the presence of lymph node metastases and poor tumour differentiation.

Old and new perspectives in the management of high-risk, locally advanced or recurrent, and metastatic vulvar cancer

During the last decades there has been a continuing evolution in the surgical approach of squamous cell carcinoma of the vulva that has been traditionally treated with radical vulvectomy and bilateral inguinal-femoral lymphadenectomy. Patients with T1 tumour are usually treated with radical local excision, if the lesion is unifocal and the remainder of the vulva is normal. Patients with T1a disease have no risk of groin metastases and do not need lymphadenectomy, whereas those with T1b disease need ipsilateral inguinal-femoral lymphadenectomy if the lesion is lateral, and bilateral lymphadenectomy if the lesion is midline. Modifications of the surgical technique of deep femoral lymphadenectomy and the mapping of sentinel node can offer new interesting therapeutic perspectives. Postoperative adjuvant pelvic and groin irradiation is warranted for patients with two or more or macroscopically involved groin nodes. Locally advanced squamous cell carcinoma of the vulva has been long surgically treated with en-block radical vulvectomy and bilateral inguinal-femoral lymphadenectomy plus partial resection of urethra, vagina or anum, or by exenteration, with severe postsurgical complications, poor quality of life, and unsatisfactory survival rates. 5-Fluorouracil [5-FU] or 5-FU- and cisplatin-based chemotherapy concurrent with irradiation followed by tailored surgery represents an attractive therapeutic option for advanced disease, planned to avoid such ultra-radical surgical procedures and, hopefully, to improve patient outcome. Chemotherapy has also been used in neoadjuvant setting, with contrasting and generally unsatisfactory results, and in palliative treatment of patients with distant metastases. Surgery is the primary treatment also for vulvar malignancies other than squamous cell carcinoma, whereas the clinical usefulness of adjuvant irradiation or chemotherapy is still to be defined. Primary chemoradiation can be also used for advanced carcinoma of the Bartholin gland or for advanced adenocarcinoma associated with extramammary Paget's disease. The drugs used for chemotherapy of metastatic melanomas or sarcomas of the vulva are the same employed for the melanomas or sarcomas developed in other sites.

Neoadjuvant chemoradiation for advanced primary vulvar cancer

BACKGROUND

In advanced stage primary vulvar cancer, treatment is tailored to individual patient needs. Combined treatment modalities have been developed, using chemotherapy, radiotherapy and surgery.

OBJECTIVES

To determine whether the combined treatment strategy using concurrent neoadjuvant chemoradiation therapy followed by surgery is effective and safe in vulvar cancer patients with advanced primary disease. Main outcomes of interest were: types of surgical intervention following chemoradiation and survival, recurrence and complication rates.

SEARCH STRATEGY

We searched the Cochrane Gynaecological Cancer Review Group Specialised Register. The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE (PubMed), EMBASE, CANCERLIT, other databases and reference lists of articles. The latest search was conducted on 12 March 2005.

SELECTION CRITERIA

Studies of curative treatment of patients with advanced, primary squamous cell carcinoma of the vulva were included. Treatment included concurrent radiotherapy and chemotherapy, followed by surgery.

DATA COLLECTION AND ANALYSIS

Twenty-eight abstracts and papers were selected either by the search strategy or by checking the cross references. Randomised controlled trials (RCTs) were not available. Five studies met the inclusion criteria. (Eifel 1995; Landoni 1996; Montana 2000; Moore 1998; Scheistroen 1993). Two authors (HCvD, MV-L) independently assessed trial quality and extracted data. Study authors were contacted for additional information. Adverse effects information was collected from the trials.

MAIN RESULTS

Chemotherapy was given uniformly within each of the five selected studies. However, four different chemoradiation schedules were applied. Radiotherapy dose fractionation techniques, fields and target definitions varied. Skin toxicity was observed in nearly all patients. Wound breakdown, infection, lymphedema, lymphorrhea and lymphoceles were also common. Operability was achieved in 63 to 92% of cases in the four studies using 5FU and CDDP or 5FU and MMC. In contrast, only 20% of the patients who received Bleomycin were operable after chemoradiation. After a follow up of 5 to 125 months, 26 to 63% of participants were alive and well. A total of 27 to 85% of participants died due to treatment related causes or disease. The five studies included in this review show that preoperative chemoradiotherapy reduces tumour size and improves operability. However, complications of treatment are considerable and information on the effects of quality of life (QOL) is not available. Furthermore, treatment results of the respective studies diverge considerably.

AUTHORS' CONCLUSIONS

Patients with inoperable primary tumours or lymph nodes benefit from chemoradiation if an operation can be performed. In patients with large tumours that can only be treated with anterior and/or posterior exenteration complications of neoadjuvant therapy might outweigh complications of exenterative surgery. With the current knowledge neoadjuvant therapy is not justified in patients with tumours that can be adequately treated with radical vulvectomy and bilateral groin node dissection alone.

Intensity-modulated radiotherapy for the treatment of vulvar carcinoma: A comparative dosimetric study with early clinical outcome

OBJECTIVES

To assess early clinical outcome of intensity-modulated radiation therapy (IMRT) in the treatment of vulvar cancer and compare dosimetric parameters with 3D conformal radiotherapy (3D CRT).

METHODS

Fifteen patients with vulvar cancer were treated with IMRT. Seven patients were treated with preoperative chemoradiation, and 8 patients were treated with adjuvant postoperative radiation therapy. Median dose was 46 Gy in the preoperative and 50.4 Gy in the postoperative group.

RESULTS

The mean volume of small bowel, rectum, and bladder that received doses in excess of 30 Gy with IMRT was reduced when compared with 3D CRT. Treatment was well tolerated, and only 1 patient had acute Grade 3 small-bowel toxicity. Median follow-up was 12 months. In the preoperative group, 5 patients (71%) had clinical complete response and 3 patients (42.8%) had pathologic complete response. In the adjuvant group, 2 patients had recurrences in the treatment field. No patients had late Grade 3 toxicity. The 2-year actuarial disease-specific survival was 100%.

CONCLUSIONS

Intensity-modulated RT appears to offer advantages over 3D CRT treatment of vulvar cancer by elimination of dose modulation across overlapping regions and reduction of unnecessary dose to the bladder, rectum, and small bowel. Early results with a small number of patients show promising results, with a low incidence of severe toxicity.

Gynaecological cancer surgery

Cancers of the female genital tract account for a significant proportion of cancers in women. Surgery plays a major role in the management of these patients. As a single modality, it provides definitive treatment for early-stage cancers and contributes to the management of patients with advanced cancers as part of multimodality treatment. Surgery can involve relatively simple procedures, such as wide local excision for microinvasive lesions of the vulva. However, for more advanced cancers, such as metastatic ovarian cancer, surgery can be very complex indeed, at times requiring resection of non-gynaecological organs, such as small or large bowel. Extensive surgical training and experience is needed to successfully manage patients with these challenging conditions, and this has resulted in the development of the subspecialty of gynaecological oncology. This chapter discusses the place of surgery in the treatment of individual gynaecological cancers.

Carcinoma of the vulva: Combined modality treatment

One of the most significant developments in recent decades in the management of malignant diseases is the recognition that surgery, radiation, and chemotherapy have limited curative potential. Along with this recognition has come the realization that although some patients can be cured with one of these modalities alone, the judicious combination of these modalities can result in better outcome. Carcinoma of the vulva, a disease that presents challenges with its management because of its anatomic location, affinity for spread to the lymph nodes, and incidence in elderly patients, lends itself to the use of this multimodality approach. The specific purpose of this approach is to decrease the sequelae of radical surgery. In addition, patients that could not be considered candidates for any treatment, such as patients with unresectable nodes, can be offered therapy with potential of cure. The patients with moderately or very advanced disease should be considered for the combination of chemotherapy, radiation, and surgery. This combined therapy results in better outcome with lesser morbidity. The studies that have been carried out in recent years for patients with advanced carcinoma of the vulva have helped to establish treatment guidelines that can be followed with confidence until more information becomes available.

Squamous-cell carcinoma of the vulva: locally advanced disease

About 30-40% of vulvar cancers present with International Federation of Gynecology and Obstetrics (FIGO) (clinical) stage III or IV disease. Although surgical staging was introduced by FIGO in 1988 and hard data on this system are still relatively few, a review of our own patients suggests that this percentage of patients with advanced stage vulvar cancer probably still holds. We have considered carcinoma of the vulva to be locally advanced when the primary or recurring tumour cannot be locally managed by a radical vulvar resection. Current approaches to the treatment of locally advanced vulvar cancer include ultraradical surgery, radiotherapy, chemo-radiotherapy and a combination of treatment modalities. This chapter reviews the current approaches to the treatment of locally advanced vulvar cancer.

Contemporary management of primary carcinoma of the vulva

Over the last 100 years the treatment of vulvar cancer has evolved dramatically. The adoption of radical surgical approaches brought high cure rates, but often with very significant physical and psychosexual morbidity. In the last 20 years, there has been an increasing emphasis on conservative and multimodality treatment. There is, however, good evidence that optimal outcomes are dependent on treatment in specialized multidisciplinary tertiary referral centers.

Preoperative chemo-radiation for carcinoma of the vulva with N2/N3 nodes: a gynecologic oncology group study

PURPOSE

To determine if patients with carcinoma of the vulva, with N2/N3 lymph nodes, could undergo resection of the lymph nodes and primary tumor following preoperative chemo-radiation. METHODS AND MATERILAS: Fifty-two patients were entered in the study, but six patients did not meet the criteria of the protocol and were excluded. The remaining 46 patients are the subject of this report. Patients underwent a split course of radiation, 4760 cGy to the primary and lymph nodes, with concurrent chemotherapy, cisplatin/5-FU, followed by surgery.

RESULTS

Four patients did not complete the chemo-radiation, because three expired and one refused to complete the treatment. Four patients who completed chemo-radiation did not undergo surgery, because two of them died of non-cancer-related causes, and in the other two patients, the nodes remained unresectable. Following chemo-radiation, the disease in the lymph nodes became resectable in 38/40 patients. Two patients who completed the course of chemo-radiation did not undergo surgery as per protocol because of pulmonary metastasis. One underwent radical vulvectomy and unilateral node dissection and the other radical vulvectomy only. The specimen of the lymph nodes was histologically negative in 15/37 patients. Nineteen patients developed recurrent and/or metastatic disease. The sites of failure were as follows: primary area only, 9; lymph node area only, 1; primary area and distant metastasis, 1; distant metastasis only, 8. Local control of the disease in the lymph nodes was achieved in 36/37 and in the primary area in 29/38 of the patients. Twenty patients are alive and disease-free, and five have expired without evidence of recurrence or metastasis. Two patients died of treatment-related complications.

CONCLUSION

High resectability and local control rates of the lymph nodes were obtained in patients with carcinoma of the vulva with N2/N3 nodes treated preoperatively with chemo-radiation.

Progress in gynecologic cancer detection and treatment

Slow but steady progress has been made in the earlier diagnosis and better treatment of gynecological cancers, particularly over the last 50 years. Cervical cytology screening programs, where implemented, have led to a remarkable reduction in both the incidence and mortality from clinically invasive cervical cancer. This relatively simple technology has been truly one of the major success stories of modern medicine, but unfortunately this technique has not been uniformly applied to all women in the world, particularly to women in developing countries. New research into cervical cancer etiology, the role of HPV, and the development of vaccines against this virus offer a great hope particularly for developing countries. In addition, the combination of radiotherapy and chemotherapy has resulted in a marked improvement in outcome results for women with advanced cervical cancer. Ovarian cancer has seen the development of effective chemotherapy strategies for this disease. Currently this disease remains one of the major scourges in industrialized countries but the continued evolution of knowledge with regard to optimum sequencing of chemotherapeutic agents and surgery offers the prospect for better outcomes, less morbidity and a better quality of life. Ongoing research into the development of newer chemotherapeutic agents and a better understanding of the actual mechanisms regarding the efficacy of chemotherapy and drug resistance offers great promise for the future. Endoscopic surgery for staging and also for therapy shows promise for improved quality of life as well as outcomes for patients in the future and offers the challenge of trying to make this technology readily available to all women in the world. As we gain a better understanding of the molecular basis of disease and health we will truly be able to intervene in a preventive mode in the new millennium.

Early clitoral carcinoma successfully treated by radiotherapy and bilateral inguinal lymphadenectomy

A 42 year-old female presented with an early stage IB squamous cell carcinoma involving the clitoris. She was treated with radical radiotherapy to the clitoris and peri-clitoral region and bilateral inguinal lymphadenectomy. The treatment was well tolerated. The vulvar appearance, sensation and orgasmic function have not been impaired. There has been no recurrence during five years of follow-up. Radiotherapy and bilateral inguinal lymphadenectomy are an effective therapeutic option in early stage IB carcinoma involving the clitoris in sexually active females.

Radical resection of vulvar malignancies: a paradigm shift in surgical approaches

Significant changes have occurred over the past two decades in the management of vulvar cancer. The most important changes have been the individualization of care for all patients, and the introduction of a multidisciplinary team approach. Radiation has been progressively incorporated into treatment protocols, and more recently chemoradiation has been investigated.

Irradiation in carcinoma of the vulva: factors affecting outcome

PURPOSE

This report reviews the increasing role of radiation therapy in the management of patients with histologically confirmed vulvar carcinoma, based on a retrospective analysis of 68 patients with primary disease (2 in situ and 66 invasive) and 18 patients with recurrent tumor treated with irradiation alone or combined with surgery.

METHODS AND MATERIALS

Of the patients with primary tumors, 14 were treated with wide local excision plus irradiation, 19 received irradiation alone after biopsy, 24 were treated with radical vulvectomy followed by irradiation to the operative fields and inguinal-femoral/pelvic lymph nodes, and 11 received postoperative irradiation after partial or simple vulvectomy. The 18 patients with recurrent tumors were treated with irradiation alone. Indications and techniques of irradiation are discussed in detail.

RESULTS

In patients treated with biopsy/local excision and irradiation, local tumor control was 92% to 100% in Stages T1-3N0, 40% in similar stages with N1-3, and 27% in recurrent tumors. In patients treated with partial/radical vulvectomy and irradiation, primary tumor control was 90% in patients with T1-3 tumors and any nodal stage, 33% in patients with any T stage and N3 lymph nodes, and 66% with recurrent tumors. The actuarial 5-year disease-free survival rates were 87% for T1N0, 62% for T2-3N0, 30% for T1-3N1 disease, and 11 % for patients with recurrent tumors; there were no long-term survivors with T4 or N2-3 tumors. Four of 18 patients (22%) treated for postvulvectomy recurrent disease remain disease-free after local tumor excision and irradiation. In patients with T1-2 tumors treated with biopsy/wide tumor excision and irradiation with doses under 50 Gy, local tumor control was 75% (3 of 4), in contrast to 100% (13 of 13) with 50.1 to 65 Gy. In patients with T3-4 tumors treated with local wide excision and irradiation, tumor control was 0% with doses below 50 Gy (3 patients) and 63% (7 of 11) with 50.1 to 65 Gy. In patients with T1-2 tumors treated with partial/radical vulvectomy and irradiation, local tumor control was 83% (14 of 17), regardless of dose level, and in T3-4 tumors, it was 62% (5 of 8) with 50 to 60 Gy and 80% (8 of 10) with doses higher than 60 Gy. The differences are not statistically significant. There was no significant dose response for tumor control in the inguinal-femoral lymph nodes; doses of 50 Gy were adequate for elective treatment of nonpalpable lymph nodes, and 60 to 70 Gy controlled tumor growth in 75% to 80% of patients with N2-3 nodes when administered postoperatively after partial or radical lymph node dissection. Significant treatment morbidity included one rectovaginal fistula, one case of proctitis, one rectal stricture, four bone/skin necroses, four vaginal necroses, and one groin abscess.

CONCLUSIONS

Irradiation is playing a greater role in the management of patients with carcinoma of the vulva; combined with wide local tumor excision or used alone in T1-2 tumors, it is an alternative treatment to radical vulvectomy, with significantly less morbidity. Postradical vulvectomy irradiation in locally advanced tumors improves tumor control at the primary site and the regional lymphatics in comparison with reports of surgery alone.

Preoperative chemoradiation for advanced vulvar cancer: a phase II study of the Gynecologic Oncology Group

PURPOSE

To determine the feasibility of using preoperative chemoradiotherapy to avert the need for more radical surgery for patients with T3 primary tumors, or the need for pelvic exenteration for patients with T4 primary tumors, not amenable to resection by standard radical vulvectomy.

METHODS AND MATERIALS

Seventy-three evaluable patients with clinical Stage III-IV squamous cell vulvar carcinoma were enrolled in this prospective, multi-institutional trial. Treatment consisted of a planned split course of concurrent cisplatin/5-fluorouracil and radiation therapy followed by surgical excision of the residual primary tumor plus bilateral inguinal-femoral lymph node dissection. Radiation therapy was delivered to the primary tumor volume via anterior-posterior-posterior-anterior (AP-PA) fields in 170-cGy fractions to a dose of 4760 cGy. Patients with inoperable groin nodes received chemoradiation to the primary vulvar tumor, inguinal-femoral and lower pelvic lymph nodes.

RESULTS

Seven patients did not undergo a post-treatment surgical procedure: deteriorating medical condition (2 patients); other medical condition (1 patient); unresectable residual tumor (2 patients); patient refusal (2 patients). Following chemoradiotherapy, 33/71 (46.5%) patients had no visible vulvar cancer at the time of planned surgery and 38/71 (53.5%) had gross residual cancer at the time of operation. Five of the latter 38 patients had positive resection margins and underwent: further radiation therapy to the vulva (3 patients); wide local excision and vaginectomy necessitating colostomy (1 patient); no further therapy (1 patient). Using this strategy of preoperative, split-course, twice-daily radiation combined with cisplatin plus 5-fluorouracil chemotherapy, only 2/71 (2.8%) had residual unresectable disease. In only three patients was it not possible to preserve urinary and/or gastrointestinal continence. Toxicity was acceptable, with acute cutaneous reactions to chemoradiotherapy and surgical wound complications being the most common adverse effects.

CONCLUSION

Preoperative chemoradiotherapy in advanced squamous cell carcinoma of the vulva is feasible, and may reduce the need for more radical surgery including primary pelvic exenteration.

A trend toward more conservative surgery in gynecologic oncology

A trend toward more conservative surgical intervention is evident in the current management of many gynecologic malignancies. The trend to manage vulvar carcinoma has moved away from the standard en bloc radical vulvectomy and bilateral lymphadenectomy and now consists of more limited excision of the primary tumor as well as of the regional lymph nodes. In preinvasive cervical carcinoma, conization is preferred instead of hysterectomy. The possibility for a more conservative surgical approach is also being explored for the treatment of selected early stage and advanced or recurrent cervical carcinomas. Although the primary surgical treatment of endometrial carcinoma remains unchanged, the necessity to perform (in all cases) the more extensive procedure required for staging purposes is being challenged. In early stage borderline ovarian tumors, not only adnexectomy but cystectomy alone is considered acceptable and reexploration for staging purposes may be unwarranted. In stage IA invasive carcinoma, adnexectomy of the involved side only is probably also sufficient. In advanced ovarian carcinoma, the more aggressive cytoreduction involving multiple organ resection is being restrained. Secondary debulking is performed only on a selective basis and the routine performance of second-look laparotomy has been given up.

Combined preoperative chemoradiotherapy followed by radical surgery in locally advanced vulvar carcinoma. A pilot study

BACKGROUND

Although for decades exenterative surgery has represented the standard treatment for patients with locally advanced vulvar cancer, combined approaches, including preoperative radiation with or without chemotherapy, are now considered the treatment of choice. We report the results of a pilot study on concurrent chemoradiotheraphy followed by radical surgery for patients with locally advanced squamous cell carcinomas of the vulva.

METHODS

Thirty-one patients with squamous cell carcinoma of the vulva were treated with two courses of combination chemotherapy mitomycin C, 15 mg/m2 intravenously (i.v.) on Day 1, and 5-fluorouracil, 750 mg/m2 i.v., in continuous 24-hour infusion on Days 1 to 5. Inguinal and pelvic lymph node chains and the vulva were irradiated (starting on the same day as the chemotherapy) up to a total dose of 36 Gy. After a 2-week interval, a second course of chemoradiotherapy was given (18 Gy on the vulvar region only). After 2 weeks, patients underwent radical surgery.

RESULTS

An objective response was observed in 22 of 24 primary cases (91.6%) and in 7 of 7 recurrent cases. All but two unresponsive patients underwent radical surgery. The postoperative morbidity rate was 65% (19 of 29 patients), and the mortality rate was 13.8% (4 of 29 patients). Five of nine patients (55%) with biopsy-proven inguinal lymph node metastases showed no residual lymph node disease in the surgical specimen. The recurrence rate was 31.8% and the medial follow-up time was 34 months.

CONCLUSIONS

Chemoradiotherapy seems to be effective for squamous cell carcinoma of the vulva. If treatment-related morbidity could be decreased, such a combined approach might offer a new perspectives for a conservative treatment of locally advanced vulvar cancer.

Vulvar squamous cell carcinoma

Squamous cell carcinoma of the vulva is a rare disease, mainly seen in elderly women. Risk factors are advanced age, an immunocompromised status, longstanding vulvar dystrophy, VIN, a history of vulvar human papillomavirus infection, and a history of cervical cancer. Vulvar cancer should be considered as a skin tumor and detection is possible in an early stage. However, because of patients' and doctors' delay, one in three vulvar cancers is not treated before an advanced stage. The tumor metastasizes mainly lymphatogenic. Spread starts in the inguinal lymph nodes. In the middle of this century, standard treatment, consisting of an en bloc dissection of the vulva and inguinal lymph nodes has been developed and applied. As a result, considerably improved survival rates were achieved: up to 90% 5-year survival rates for patients without lymph node metastases. However, complication rates were high. In recent years, a more individualized approach has replaced standard treatment. Surgical treatment now depends on the localization, size and extent of the tumor, and is followed or preceded by radiotherapy in selected cases. The role of chemotherapy in advanced disease is currently being studied in several referral centers. The most important success in the treatment of vulvar cancer in recent years is the maintenance of high survival rates despite considerably less extensive surgical treatment, resulting in lower complications rates. An important challenge for the near future will be the improvement of the management of advanced disease. However, an even more difficult issue may be the prevention of such large lesions. The reduction of treatment delays requires a considerable effort in education of both health care workers and the general public.
