OBJECTIVES: High morbidity of elective inguinofemoral lymphadenectomy in early stage vulvar cancer patients urges the need for defining a group of low-risk patients in whom inguinofemoral lymphadenectomy can be safely omitted. Aim of the study was to evaluate whether in addition to 'classic' clinicopathological factors determination of EGFR expression in vulvar cancer can be helpful in defining such a 'low-risk' group. METHODS: Formalin-fixed paraffin-embedded tumor tissue samples of 197 surgically treated T1/2 patients were collected in a Tissue Micro Array (TMA). On this TMA, immunohistochemistry for EGFR was performed. Logistic regression analyses were performed including histopathological characteristics with the presence of nodal metastases as outcome. A predictive model was constructed, and absolute risks were calculated. RESULTS: EGFR expression was present in 68% of the vulvar tumors and related to the presence of lymph node metastases (OR 2.12, 95% CI 1.09-4.10). Our predictive model with only clinicopathological factors was able to define a group of patients with a likelihood of absence of lymph node metastases of 13% (95% CI 5-36), which could be decreased to 6% (95% CI 0-29) after inclusion of EGFR expression (p=0.07). CONCLUSIONS: EGFR expression is present in the majority of vulvar tumors and is associated with groin node metastases in vulvar cancer. Current classic clinicopathological predictive factors for inguinofemoral lymph node metastases with or without EGFR analysis are not strong enough for identification of "sufficiently low" risk T1/2 vulvar cancer patients. Our predictive model approach however is excellent for evaluation of new cell biological parameters, associated with clinical outcome.
The majority of patients with vulvar cancer have squamous cell carcinomas (SCC). The cornerstone of the treatment is surgery. Radical vulvectomy with "en bloc" inguinofemoral lymphadenectomy has led to a favorable prognosis but with impressive morbidity. Nowadays, treatment is more individualized with wide local excision with uni- or bilateral inguinofemoral lymphadenectomy via separate incisions as the standard treatment for early stage patients with SCC of the vulva with depth of invasion >1 mm without suspicious groins. In case of more than one intranodal lymph node metastasis and/or extranodal growth, postoperative radiotherapy on the groins and pelvis is warranted. Until now there is a limited role for primary radiotherapy on the vulva and/or groins in early stage disease. The sentinel lymph node (SLN) procedure with the combined technique (preoperative lymphoscintigraphy with a radioactive tracer and intraoperative blue dye) is a promising staging technique for patients with early stage vulvar cancer. The safety of clinical implementation of the SLN procedure and the role of additional histopathological techniques of the SLNs need to be further investigated before its wide-scale application. Patients with advanced vulvar cancer are difficult to treat. One of the problems in patients with locally advanced vulvar cancer is the high incidence of concomitant bulky lymph nodes in the groin(s). Ultraradical surgery in case of resectable disease will lead to impressive morbidity because of the exenterative-type procedure. (Chemo)radiation with or without surgery should be regarded as the first choice for patients with locally advanced vulvar cancer only when primary surgery will necessitate performance of a stoma. Further studies are needed to determine the optimal combined modality treatment in these patients. Due to the fact that vulvar cancer is a rare disease, further clinical studies will only be possible, when international collaborative groups will join forces in order to perform clinical trials, in which different treatment options such as SLN procedure, primary radiotherapy on the groins and multimodality treatment for advanced disease will be investigated.
AIM: The radical surgical approach in the treatment of vulvar cancer patients has led to a favorable prognosis for the majority of the patients with early stage squamous cell cancer. However, the morbidity is impressive, leading to more individualized treatment. The aim of this review is to give an overview of the management of vulvar cancer. METHODS: We have reviewed the literature on the modifications in treatment of vulvar cancer with the emphasis on surgery and radiotherapy for primary disease. RESULTS: While surgery is the cornerstone of treatment for early stage squamous cell vulvar cancer (with wide local excision and uni- or bilateral inguinofemoral lymphadenectomy via separate incisions as standard treatment), until now there has been a limited role for primary radiotherapy although this may be an attractive alternative for the inguinofemoral lymphadenectomy in the future. The sentinel lymph node procedure with the combined technique (preoperative lymphoscintigraphy with (99m)technetium-labeled nanocolloid and Patente Blue) is a promising staging technique for patients with vulvar cancer. The clinical implementation of the sentinel lymph node procedure and the role of additional histopathological techniques of the sentinel lymph nodes have to be investigated. In advanced vulvar cancer, chemoradiation followed by surgery should be regarded as the treatment of first choice for these patients. CONCLUSIONS: Due to the rarity of vulvar cancer it is quite clear that further studies will have to be performed by international collaborative groups. The sentinel lymph node procedure and primary radiotherapy are promising methods to reduce morbidity of treatment, but their safety needs to be studied in clinical trials.
To determine the effectiveness of annual gynaecological screening (pelvic examination, transvaginal ultrasound, and CA-125), a prospective cohort study of women at high risk for hereditary ovarian cancer was conducted. Women were offered DNA analysis followed by either annual screening or prophylactic bilateral salpingo-oophorectomy (BSO). Study population consisted of 512 high-risk women (median follow-up 2.07 years, range 0-9.4 years): 265 women (52%) had a BRCA mutation. Persisting abnormalities indicated diagnostic surgery in 24 women resulting in one primary ovarian cancer FIGO stage IIIc was found. The effectiveness of screening was studied by calculating the probability of finding ovarian cancers in the BRCA-1 and BRCA-2 carrier group and comparing this to the identified number of ovarian cancers. The number of ovarian cancer patients found at surveillance was in accordance with the predicted number of ovarian cancers. A total number of 169 women underwent prophylactic BSO: one ovarian cancer stage IIb was found. In conclusion, the surveillance programme for hereditary ovarian cancer does identify patients with ovarian cancer but is very inefficient considering the high number of surveillance visits and the advanced stage of ovarian cancer in the identified patient. For prevention of advanced stage ovarian cancer, prophylactic BSO from age 35-40 years is a more efficient alternative.
PURPOSE: To assess the occurrence of high-risk epithelial lesions in women of breast cancer families with and without a BRCA mutation. PATIENTS AND METHODS: Prospective study of women at very high risk of breast cancer undergoing prophylactic mastectomy (68 BRCA1 mutation carriers, 14 BRCA2 mutation carriers and 24 non-BRCA mutation carriers). RESULTS: The prevalence of high-risk lesions is equal in women with a BRCA1 or a BRCA2 mutation, but is higher in non-BRCA mutation carriers: all lesions 43% versus 71% (p=0.02), atypical lobular hyperplasia 26% versus 67% (p=0.001), atypical ductal hyperplasia 17% versus 42% (p=0.01), lobular carcinoma-in situ 15% versus 29% (p=0.10) and ductal carcinoma-in situ 9% versus 17% (p=0.25). The presence of high-risk lesions is related to absence of a BRCA mutation and to age over 40 years. CONCLUSION: Women with an autosomal dominant family history for breast cancer, with and without a BRCA mutation are prone to develop high-risk epithelial lesions, especially over 40 years.
Two separate pathways leading to vulvar carcinoma have been suggested. First, a human papillomavirus (HPV)-dependent pathway, in which premalignant stages of vulvar cancer are the classic vulvar intraepithelial neoplasia (VIN) lesions. Second, an HPV-independent pathway, associated with differentiated VIN III lesions and/or lichen sclerosus. To obtain insight into the mechanisms underlying these pathways, we determined the relationship between HPV DNA and the expression of p14(ARF) and p16(INK4A) in non- and (pre)malignant vulvar lesions. Seventy-three archival samples of non- and (pre)neoplastic vulvar lesions were selected and tested for hr-HPV DNA using a broad-spectrum HPV detection/genotyping assay (SPF(10)-LiPA) and the expression of p14(ARF) and p16(INK4A). The prevalence of HPV increased with the severity of the classic VIN lesions; in VIN I no hr-HPV was detected, in VIN II 43%, and in VIN III 71% of the samples were hr-HPV-positive. Roughly the same was true for the expression of p14(ARF) and p16(INK4A). The simultaneous expression of p14(ARF) and p16(INK4A) was highly associated with the presence of hr-HPV DNA. Hr-HPV was detected in only a single case of the differentiated VIN III lesions, whereas no expression of p14(ARF) was found and 16(INK4A) was present in only two cases. All 16 samples of vulvar cancer were hr-HPV DNA- negative, although in respectively 63% and 25%, p14(ARF) and p16(INK4A) was expressed. No relation was found between hr-HPV and the expression of p14(ARF) and p16(INK4A) in the 20 nonneoplastic vulvar lesions. Our results provide further evidence that vulvar squamous cell carcinoma is a multifactorial disease that develops from two different pathways. First, an HPV-dependent pathway with a remarkable resemblance to CIN lesions and cervical carcinoma and second, an HPV-independent pathway in which differentiated VIN III lesions that are hr-HPV-negative may be precursors.
OBJECTIVES: The treatment of choice for patients with advanced stage cervical cancer is (chemo)radiotherapy. Gynaecologic side effects consist of loss of ovarian function and destruction of the endometrium, resulting in infertility and premature ovarian failure. In premenopausal patients estrogens are prescribed to prevent climacteric symptoms. In general, no progestagens are added to the hormone replacement therapy because of the assumption of complete destruction of the basal layer of the endometrium after pelvic radiotherapy. The aim of this report is to show the different presentations of endometrial activity after curative radiotherapy in patients with cervical cancer. METHODS: Presentation of four patients who developed symptoms of residual endometrial activity. RESULTS: In two patients, proliferation of functional endometrium led to hematocolpos and hematometrum with abdominal pain. The third patient underwent ovarian transposition and developed regular periods 3 months after finishing the radiotherapy. The fourth patient underwent trachelectomy with radiotherapy because of narrow tumour free margins. She developed vaginal blood loss after starting estrogens. CONCLUSIONS: These patients show that in premenopausal patients, curative radiotherapy until 80Gy, may lead to symptoms of residual functional endometrium, e.g. hematometrum, hematocolpos, (ir)regular vaginal blood loss. In our opinion patients should be advised to use estrogens in combination with a progestogen, instead of unopposed estrogens, to prevent stimulation of residual functional endometrium. Tibolone may be an appropriate alternative hormone replacement therapy especially with the advantage of low androgen effects which might support the sexual functions, and the decrease of breast density.
The treatment of patients with early-stage squamous-cell carcinoma of the vulva (with a depth of invasion > 1 mm), i.e. stage T1 with a tumour diameter < or = 2 cm or T2 with a diameter > 2 cm without suspect groin nodes on palpation, has become less radical; in this way, the complications can be reduced without compromising the generally favourable prognosis. Wide local excision with tumour-free margins of 2 cm appears to be a safe option for the local treatment. Uni- or bilateral inguinofemoral lymphadenectomy with separate incisions is currently part of the standard treatment. The complications associated with this standard surgical treatment remain significant: there are frequent disorders of wound healing, wound infections, lymphoceles, lymphoedema and effects on psychosexual behaviour. The minimal invasive sentinel lymph-node procedure is a promising technique in patients with early-stage squamous-cell carcinoma of the vulva, but the safety of the procedure must still be proven.
OBJECTIVES: There is an increasing interest among gynecologic oncologists to implement the sentinel lymph node (SLN) procedure in vulvar cancer patients in clinical practice. However, the safety of this promising method of staging still has to be proven in a randomized trial. MATERIALS AND METHODS: Two vulvar cancer patients are reported to illustrate pitfalls in the sentinel lymph node procedure. RESULTS: The phenomena of bypassing the sentinel lymph node and confusion about the number of removed sentinel lymph nodes are presented and discussed. CONCLUSION: Gynecological oncologists who perform the sentinel lymph node procedure in vulvar cancer patients should perform this technique by following a strict protocol and within the protection of a clinical trial.

Vulvar cancer is a rare disease. Squamous-cell carcinomas account for 90% of vulvar cancers. The main mode of spread is lymphogenic to the inguinofemoral lymph nodes. Therefore, elective uni- or bilateral inguinofemoral lymphadenectomy is part of the standard treatment in combination with radical (wide) local excision of the vulvar tumour. Lymph drainage studies in relation to the biological behaviour of vulvar cancer are presented, as well as the anatomy and surgery of the groin. The sentinel lymph node procedure is a relatively new method of staging in vulvar cancer which may lead to the omission of inguinofemoral lymphadenectomy in those patients identified as not having inguinofemoral lymph node metastases. The accuracy of this technique appears to be high, but its safety still has to be proven. Moreover, the role of additional histopathological techniques for the examination of the sentinel lymph nodes needs to be established.

The sentinel lymph node procedure is a relatively new, minimally-invasive method for the assessment of nodal status in malignancies such as breast cancer, cutaneous melanoma and vulvar cancer. Although highly accurate, this new method is inevitably associated with a certain false-negative rate, possibly leading to worse survival in a small subset of patients. The clinical implementation of the sentinel lymph node procedure is therefore a matter of ongoing debate, especially among doctors. The aim of this study was to assess opinions on the acceptable false-negative rate of the sentinel lymph node procedure in patients with vulvar cancer, who in the past had undergone standard routine radical vulvectomy and complete inguinofemoral lymphadenectomy (and frequently experienced complications), and in gynecologists treating patients with vulvar cancer. Structured questionnaires were sent to both patients and gynecologists. The patients had been treated for vulvar cancer between 1985 and 1993, and were all in complete remission with a median follow-up of 118 months (range: 76-185). Questions to the patients dealt with experienced side-effects of the standard treatment and opinion on the acceptable false-negative rate of the sentinel lymph node procedure. The response rate among patients was 91% (106/117). Forty per cent of the patients experienced one or more infections in the legs (cellulitis) and 49% of the patients still experience either severe pain and/or severe lymphedema in the legs. Sixty-six per cent of the patients preferred complete inguinofemoral lymphadenectomy in preference to a 5% false-negative rate of the sentinel lymph node procedure of 5%. Their preference was not related to age or the side-effects they had experienced. The response rate among gynecologists was 80% (80/100), of whom 60% were willing to accept a 5-20% false-negative rate of the sentinel lymph node procedure. While gynecologists may consider the sentinel lymph node procedure to be a promising diagnostic tool, the majority of vulvar cancer patients, who have undergone complete inguinofemoral lymphadenectomy in the past and have frequently experienced complications, would not advise introduction of this technique because they do not want to take any risk of missing a lymph node metastasis.
PURPOSE: To determine the diagnostic accuracy of the sentinel lymph node procedure in patients with squamous cell carcinoma of the vulva and to investigate whether step sectioning and immunohistochemistry of sentinel lymph nodes increase the sensitivity for detection of metastases. PATIENTS AND METHODS: Between July 1996 and July 1999, 59 patients with primary vulvar cancer were entered onto a two-center prospective study. All patients underwent sentinel lymph node procedure with the combined technique (preoperative lymphoscintigraphy with technetium-99m-labeled nanocolloid and intraoperative blue dye). Radical excision of the primary tumor with uni- or bilateral inguinofemoral lymphadenectomy was performed subsequently. Sentinel lymph nodes and lymphadenectomy specimens were sent for histopathologic examination separately. Sentinel lymph nodes, negative at the time of routine pathologic examination, were re-examined with step sectioning and immunohistochemistry. RESULTS: In 59 patients, 107 inguinofemoral lymphadenectomies were performed (11 unilateral and 48 bilateral). All sentinel lymph nodes, as observed on preoperative lymphoscintigram, were identified successfully intraoperatively. Routine histopathologic examination showed lymph node metastases in 27 groins, all of which were detected by the sentinel lymph node procedure. The negative predictive value for a negative sentinel lymph node was 100% (97.5% confidence interval [CI], 95% to 100%). Step sectioning and immunohistochemistry showed four additional metastases in 102 sentinel lymph nodes (4%; 95% CI, 1% to 9%) that were negative at the time of routine histopathologic examination. CONCLUSION: Sentinel lymph node procedure with the combined technique is highly accurate in predicting the inguinofemoral lymph node status in patients with early-stage vulvar cancer. Future trials should focus on the safe clinical implementation of the sentinel lymph node procedure in these patients. Step sectioning and immunohistochemistry slightly increase the sensitivity of detecting metastases in sentinel lymph nodes and should be included in these trials.
UNLABELLED: In patients with early-stage squamous cell cancer of the vulva, inguinofemoral lymphadenectomy is performed primarily as a diagnostic procedure. The morbidity of this procedure, however, is not negligible. The aim of this study was to evaluate the feasibility of minimally invasive detection of the sentinel inguinofemoral lymph node (SILN) and to investigate whether the histopathology of the SILNs is representative of that of the other non-SILNs. METHODS: Patients with early-stage squamous cell cancer of the vulva, planned for resection of the primary tumor and uni- or bilateral inguinofemoral lymphadenectomy, were eligible for the study. Technetium-99m-labeled nanocolloid was injected intradermally at four locations around the tumor the day before operation. Images were recorded immediately and after 2.5 hr using a gamma camera. SILN locations were marked on the overlying groin skin. The next day, during general anesthesia, blue patent dye was injected intradermally at the same locations around the tumor. During the operation SILNs were identified at the place indicated using a handheld gamma-detection probe. It was noted if SILNs were found by the probe, by blue dye or by both techniques. After resection of the SILNs, a standard inguinofemoral lymphadenectomy was performed. The results of histopathology of the SILNs were compared with those of the non-SILNs. RESULTS: The procedure was well tolerated by 10 of 11 patients. One patient, initially agreeing to participate, refused the injection of tracer because of fear of pain. In all 10 patients, identification of the SILNs was successful. The mean time for identification was 11 min. Identification of SILNs was primarily performed using the hand probe in all patients, whereas in 10 of 18 removed SILNs afferent lymph channels were also blue stained (56%). In 8 patients, pathologic examination showed no metastatic disease in both SILNs and non-SILNs, whereas in 2 patients metastases in the SILNs (one and two metastatic lymph nodes, respectively), as well as in other non-SILNs, were found. CONCLUSION: This study shows that identification of SILNs in squamous cell cancer of the vulva is feasible with preoperatively administered 99mTc-labeled nanocolloid. Intraoperatively administered blue dye was only useful for confirmation of identification with nanocolloid. To date, no false-negative SILNs have been found, but expansion of the study is necessary to determine the possible clinical application of this new diagnostic technique.
In this report two cases of the coincidence of hyperimmunoglobulinemia D syndrome (HIDS) and pregnancy are described. HIDS is not associated with complications in pregnancy or disturbance in fetal outcome; the frequency of attacks diminishes during pregnancy; HIDS probably inherits via an autosomal recessive trait and is not transmitted to children of patients.
A case is reported in which enlarged, hyperechogenic lungs, ascites and polyhydramnios on prenatal ultrasound were indications of a partial tracheal agenesis and tracheoesophageal fistula. A review of the literature is given to assist clinicians in effectively counselling women in whom this ultrasound abnormality is detected.
