Medial Inguino-Femoral Lymphadenectomy for Vulvar Cancer: An Approach to Decrease Lymphedema without Compromising Survival. Cancers (Basel) 2021; 13:cancers13225806. [PMID: 34830958 PMCID: PMC8616189 DOI: 10.3390/cancers13225806] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Revised: 10/19/2021] [Accepted: 11/16/2021] [Indexed: 11/22/2022] Open
Abstract
Simple Summary This prospective study has demonstrated that if the inguinal nodes medial to the lateral border of the femoral artery and the femoral nodes are negative in patients with vulvar cancer, the chances of having a positive node lateral to the artery are less than 1 in 10,000. About one-third of groin nodes are situated lateral to the femoral artery, so leaving these nodes in situ if the medial nodes are negative should significantly decrease the incidence and severity of lower limb lymphedema, without compromising survival. Abstract Background: Lower limb lymphedema is a long-term complication of inguino-femoral lymphadenectomy and is related to the number of lymph nodes removed. Our hypothesis was that lymph nodes lateral to the femoral artery could be left in situ if the medial nodes were negative, thereby decreasing this risk. Methods: We included patients with vulvar cancer of any histological type, even if the cancer extended medially to involve the urethra, anus, or vagina. We excluded patients whose tumor extended (i) laterally onto the thigh, (ii) posteriorly onto the buttocks, or (iii) anteriorly onto the mons pubis. After resection, the inguinal nodes were divided into a medial and a lateral group, based on the lateral border of the femoral artery. Results: Between December 2010 and July 2018, 76 patients underwent some form of groin node dissection, and data were obtained from 112 groins. Approximately one-third of nodes were located lateral to the femoral artery. Positive groin nodes were found in 29 patients (38.2%). All patients with positive nodes had positive nodes medial to the femoral artery. Five patients (6.6%) had positive lateral inguinal nodes. The probability of having a positive lateral node given a negative medial node was estimated to be 0.00002. Conclusion: Provided the medial nodes are negative, medial inguino-femoral lymphadenectomy may suffice and should reduce lower limb lymphedema without compromising survival.

Abstract
The standard radical mutilating surgery for the treatment of invasive vulval carcinoma is, today, being replaced by a conservative and individualised approach. Surgical conservative modifications that are currently considered safe, regarding vulval lesion, are separate skin vulval-groin incisions, drawn according to the lesion diameter, and wide local radical excision or partial radical vulvectomy with 1-2 cm of clinically clear surgical margins. Regarding inguinofemoral lymph nodes management, surgical conservative modifications not compromising patient survival are omission of groin lymphadenectomy only when tumour stromal invasion is ≤ 1 mm, unilateral groin lymphadenectomy only in well-lateralised early lesions and total or radical inguinofemoral lymphadenectomy with preservation of femoral fascia when full groin resection is needed. Sentinel lymph node dissection is a promising technique but it should not be routinely employed outside referral centres. Pelvic nodes are better managed by radiation. Locally advanced vulval carcinoma can be managed by ultraradical surgery, exclusive radiotherapy or chemoradiation.

Abstract
BACKGROUND Vulval cancer is usually treated by wide local excision with removal of groin lymph nodes (inguinofemoral lymphadenectomy) from one or both sides, depending on the tumour location. However, this procedure is associated with significant morbidity. As lymph node metastasis occurs in about 30% of women with early vulval cancer, accurate prediction of lymph node metastases could reduce the extent of surgery in many women, thereby reducing morbidity. Sentinel node assessment is a diagnostic technique that uses traceable agents to identify the spread of cancer cells to the lymph nodes draining affected tissue. Once the sentinel nodes are identified, they are removed and submitted to histological examination. This technique has been found to be useful in diagnosing the nodal involvement of other types of tumours. Sentinel node assessment in vulval cancer has been evaluated with various tracing agents. It is unclear which tracing agent or combination of agents is most accurate. OBJECTIVES To assess the diagnostic test accuracy of various techniques using traceable agents for sentinel lymph node assessment to diagnose groin lymph node metastasis in women with FIGO stage IB or higher vulval cancer and to investigate sources of heterogeneity. SEARCH METHODS We searched MEDLINE (1946 to February 2013), EMBASE (1974 to March 2013) and the relevant Cochrane trial registers. SELECTION CRITERIA Studies that evaluated the diagnostic accuracy of traceable agents for sentinel node assessment (involving the identification of a sentinel node plus histological examination) compared with histological examination of removed groin lymph nodes following complete inguinofemoral lymphadenectomy (IFL) in women with vulval cancer, provided there were sufficient data for the construction of two-by-two tables. DATA COLLECTION AND ANALYSIS Two authors (TAL, AP) independently screened titles and abstracts for relevance, classified studies for inclusion/exclusion and extracted data. We assessed the methodological quality of studies using the QUADAS-2 tool. We used univariate meta-analytical methods to estimate pooled sensitivity estimates. MAIN RESULTS We included 34 studies evaluating 1614 women and approximately 2396 groins. The overall methodological quality of included studies was moderate. The studies included in this review used the following traceable techniques to identify sentinel nodes in their participants: blue dye only (three studies), technetium only (eight studies), blue dye plus technetium combined (combined tests; 13 studies) and various inconsistent combinations of these three techniques (mixed tests; 10 studies). For studies of mixed tests, we obtained separate test data where possible.Most studies used haematoxylin and eosin (H&E) stains for the histological examination. Additionally an immunohistochemical (IHC) stain with and without ultrastaging was employed by 14 and eight studies, respectively. One study used reverse transcriptase polymerase chain reaction analysis (CA9 RT-PCR), whilst three studies did not describe the histological methods used.The pooled sensitivity estimate for studies using blue dye only was 0.94 (68 women; 95% confidence interval (CI) 0.69 to 0.99), for mixed tests was 0.91 (679 women; 95% CI 0.71 to 0.98), for technetium only was 0.93 (149 women; 95% CI 0.89 to 0.96) and for combined tests was 0.95 (390 women; 95% CI 0.89 to 0.97). Negative predictive values (NPVs) for all index tests were > 95%. Most studies also reported sentinel node detection rates (the ability of the test to identify a sentinel node) of the index test. The mean detection rate for blue dye alone was 82%, compared with 95%, 96% and 98% for mixed tests, technetium only and combined tests, respectively. We estimated the clinical consequences of the various tests for 100 women undergoing the sentinel node procedure, assuming the prevalence of groin metastases to be 30%. For the combined or technetium only tests, one and two women with groin metastases might be 'missed', respectively (95% CI 1 to 3); and for mixed tests, three women with groin metastases might be 'missed' (95% CI 1 to 9). The wide CIs associated with the pooled sensitivity estimates for blue dye and mixed tests increased the potential for these tests to 'miss' women with groin metastases. AUTHORS' CONCLUSIONS There is little difference in diagnostic test accuracy between the technetium and combined tests. The combined test may reduce the number of women with 'missed' groin node metastases compared with technetium only. Blue dye alone may be associated with more 'missed' cases compared with tests using technetium. Sentinel node assessment with technetium-based tests will reduce the need for IFL by 70% in women with early vulval cancer. It is not yet clear how the survival of women with negative sentinel nodes compares to those undergoing standard surgery (IFL). A randomised controlled trial of sentinel node dissection and IFL has methodological and ethical issues, therefore more observational data on the survival of women with early vulval cancer are needed.

Abstract
The management of vulvar cancer has changed in the past two decades. Modern treatment of vulvar cancer must be individualized, and less radical surgery is now being performed if possible, in consideration of the quality of life (QOL) of patients. Even though the treatment now tends to be conservative, lymph nodes in all patients should be appropriately treated, with the only exception being microinvasive cancer with less than 1-mm stromal invasion. Here we review the up-to-date management of lymph nodes in patients with vulvar cancer.

Abstract
BACKGROUND Colorectal cancer is a leading cause of morbidity and mortality, especially in the Western world. The human and financial costs of this disease have prompted considerable research efforts to evaluate the ability of screening tests to detect the cancer at an early curable stage. Tests that have been considered for population screening include variants of the faecal occult blood test, flexible sigmoidoscopy and colonoscopy. Reducing mortality from colorectal cancer (CRC) may be achieved by the introduction of population-based screening programmes. OBJECTIVES To determine whether screening for colorectal cancer using the faecal occult blood test (guaiac or immunochemical) reduces colorectal cancer mortality and to consider the benefits, harms and potential consequences of screening. SEARCH STRATEGY Published and unpublished data for this review were identified by: Reviewing studies included in the previous Cochrane review; Searching several electronic databases (Cochrane Library, Medline, Embase, CINAHL, PsychInfo, Amed, SIGLE, HMIC); and Writing to the principal investigators of potentially eligible trials. SELECTION CRITERIA We included in this review all randomised trials of screening for colorectal cancer that compared faecal occult blood test (guaiac or immunochemical) on more than one occasion with no screening and reported colorectal cancer mortality. DATA COLLECTION AND ANALYSIS Data from the eligible trials were independently extracted by two reviewers. The primary data analysis was performed using the group participants were originally randomised to ('intention to screen'), whether or not they attended screening; a secondary analysis adjusted for non-attendence. We calculated the relative risks and risk differences for each trial, and then overall, using fixed and random effects models (including testing for heterogeneity of effects). We identified nine articles concerning four randomised controlled trials and two controlled trials involving over 320,000 participants with follow-up ranging from 8 to 18 years. MAIN RESULTS Combined results from the 4 eligible randomised controlled trials shows that participants allocated to screening had a 16% reduction in the relative risk of colorectal cancer mortality (RR 0.84, CI: 0.78-0.90). In the 3 studies that used biennial screening (Funen, Minnesota, Nottingham) there was a 15% relative risk reduction (RR 0.85, CI: 0.78-0.92) in colorectal cancer mortality. When adjusted for screening attendance in the individual studies, there was a 25% relative risk reduction (RR 0.75, CI: 0.66 - 0.84) for those attending at least one round of screening using the faecal occult blood test. AUTHORS' CONCLUSIONS Benefits of screening include a modest reduction in colorectal cancer mortality, a possible reduction in cancer incidence through the detection and removal of colorectal adenomas, and potentially, the less invasive surgery that earlier treatment of colorectal cancers may involve. Harmful effects of screening include the psycho-social consequences of receiving a false-positive result, the potentially significant complications of colonoscopy or a false-negative result, the possibility of overdiagnosis (leading to unnecessary investigations or treatment) and the complications associated with treatment.

Abstract
Vulvar cancer is an uncommon but devastating disease. In addition to radical vulvectomy, most patients require inguinofemoral lymphadenectomy, which often results in wound infection, wound breakdown, and chronic lymphedema. In the past, the gold standard for early lesions was radical vulvectomy with complete bilateral inguinal-femoral lymphadenectomy. This resulted in a low rate of recurrence but devastating disfigurement and high complication rates. Because only approximately 20% of patients with vulvar cancer have positive lymph nodes upon presentation, the traditional approach of inguinal-femoral lymphadenectomy for all patients resulted in many patients undergoing a morbid procedure without any real benefit. Sentinel node dissection, by removing only the nodes with the highest risk of containing metastases, offers a much less morbid alternative. In addition, because only one or two lymph nodes are removed, these can be subjected to a more thorough histopathologic analysis than conventional complete lymphadenectomy. This involves serial sectioning and immunohistochemical staining for cytokeratin antigen. Very small metastases, termed micrometastases, can be detected in this fashion. Therefore, sentinel node dissection with serial sectioning and immunohistochemical staining potentially offers a more accurate assessment of the regional nodes with less morbidity. Patients with positive sentinel nodes may then undergo additional therapy. Patients with negative sentinel nodes are theoretically at very low risk for metastases and should not require any additional treatment.

Abstract
PURPOSE This study was undertaken to correlate preoperative primary tumor size and American Joint Committee on Cancer and International Federation of Gynecology and Obstetrics categories with the risk of subclinical metastases from squamous carcinoma of the vulva to inguinofemoral nodes in patients with a palpably negative groin preoperatively. METHODS AND MATERIALS Clinical notes, operative reports, and pathology reports from 1955 to 1990 were reviewed to assign retrospectively 1969 American Joint Committee on Cancer N(0) and N(1) and 1988 International Federation of Gynecology and Obstetrics T categories. RESULTS Of 446 patients with primary carcinoma of the vulva, 226 had a groin without features indicative of lymph node metastasis. Occult groin node metastases were detected in 15.2%, 30.0%, 24.5%, and 0% of patients with T(1), T(2), T(3), and T(4) cancers, respectively. Subclinical node metastases were found in 7.0%, 22.2%, 26.9%, 34.1%, and 20.0% of patients with primary cancers measuring 1.0 cm or less, 1.1 to 2.0 cm, 2.1 to 3.0 cm, 3.1 to 5.0 cm, and larger than 5 cm, respectively. CONCLUSIONS Efficacy assessment for elective groin node irradiation and quantitative description of the radiation dose-control relationship for subclinical disease should be based on estimates of the risk of subclinical disease within the target volume. This study may help to assess the effectiveness of current therapies.

Abstract
Vulval carcinoma is relatively rare. The disease spreads from the vulva through embolization to the locoregional lymphatic station, the inguinofemoral nodes. Prior to this event cure can be achieved, but rarely predicted with certainty. This chapter reviews current therapeutic knowledge and recognizes the increasing importance of individualization of a treatment plan. The adoption of these principles will hopefully evolve a pattern of care that leads to a decrease in morbidity for those women with early tumours and less morbid but more effective strategies for those with advanced disease.

Abstract
AIM To assess the accuracy of ultrasound combined with fine-needle aspiration cytology (FNAC) in the detection of lymph node metastasis in patients with squamous cell carcinoma of the vulva. MATERIALS AND METHODS The groin nodes of 44 consecutive patients with primary squamous cell carcinoma of the vulva undergoing groin node dissection were assessed with ultrasound and FNAC. The results were compared with histology from subsequent inguinofemoral lymph node dissection. Twenty-nine patients underwent bilateral groin node dissections and 15 unilateral providing comparable data for 73 groins. RESULTS Histology demonstrated metastatic disease in 28 groins and no evidence of metastatic disease in 45. Ultrasound agreed with the histology in 67 of the 73 groins (92%), with two false-positives, four false-negatives and two indeterminate appearances. Cytology agreed with the histology in 65 of 72 FNAC samples obtained (90%), with six false-negatives, and one indeterminate result. No false-positive cytology results were seen. Ultrasound and FNAC together failed to detect metastatic disease in four groins, one with an indeterminate ultrasound appearance, another with indeterminate cytology, the two others each having a single positive inguinal node despite a negative ultrasound and FNAC. CONCLUSION The combination of ultrasound and FNAC provides a sensitive and specific tool for pre-operative assessment and may prevent unnecessary groin dissection and the attendant morbidity in selected patients with vulval cancer.

Abstract
OBJECTIVE This study compared the rates of survival, recurrence, and the occurrence of complications after surgery for vulvar cancer in selected patients treated by simple vulvectomy or wide local excision (WLE) and ipsilateral superficial inguinal lymphadenectomies (ISIL) and who were in a representative group of previous patients treated by standard radical surgery (control). MATERIALS AND METHODS Superficial inguinal lymphadenectomies were performed in 32 patients with laterally localized squamous cell tumors of 1 to 3 cm in size and without palpable lymph nodes. Eight cases, which showed histological evidence of lymph node metastasis, were submitted to conventional radical treatment and excluded from the study. Of the remaining 24 patients, 12 underwent vulvectomy, 7 hemivulvectomy, and 5 WLE. The results of this group were compared with those of 21 historical controls who previously had tumors of 1 to 3 cm and had been treated by radical vulvectomy with superficial and deep bilateral inguinal lymphadenectomy. RESULTS Dehiscence of the flaps occurred in 66.6% of the control patients and in 8.3% of the ISIL group (chi , p <.0001). There was lymphedema in 13.8% of the controls and none in the ISIL group (Fisher exact test, p <.02). Upon follow-up (3 to 8 years, results are reported for 3 years of follow-up), there were 9.5% vulvar recurrences in the controls and 12.5% in the ISIL group (Fisher exact test, p <.652 not significant). CONCLUSIONS WLE and deep local excision of the primary lesion and ISIL in selected patients with early vulvar cancer seems to be a safe alternative to the traditional radical method.

Abstract
BACKGROUND Sarcomatous neoplasms of the uterine corpus are still a challenge in terms of obtaining prognostic factors and the most optimum complementary treatment to surgery. The most important prognostic factor is stage; relapses usually appear during the first 2 years, and most patients die within the first 3 years. We have performed a multivariate study of prognostic factors, stratifying patients by stage, to determine their impact on overall survival, disease-free survival, local relapse-free survival, and distant metastasis-free survival. Special emphasis has been given to vascular and lymphatic space invasion (VLSI). METHODS Sixty patients diagnosed with uterine neoplasms with a main sarcomatous component were treated at Hospital Clínic i Universitari of Barcelona between January 1975 and June 1999. Pathologic type: 32 carcinosarcomas, 14 leiomyosarcomas, 9 adenosarcomas, and 5 endometrial stromal sarcomas. TREATMENT 58/60 surgery, 35/60 postoperative radiotherapy, 2/60 exclusive chemotherapy, and 3/60 complementary chemotherapy. FIGO stages: 43 Stage I, 4 Stage II, 11 Stage III, and 2 Stage IV. Variables analyzed: age, stage, vascular and lymphatic space invasion, myometrial invasion, mitotic index, tumor size, unicentricity/multicentricity, necrosis, and radiotherapy. STATISTICS the S and Cox proportional risk models. The partial effect of each risk factor was calculated by hazard ratio (HR) with a confidence interval of 95%. RESULTS Early stages: Multivariate analysis showed that tumor size larger than 8 cm and VLSI had an impact on overall survival (HR = 4.01 and HR = 24.45, respectively). VLSI was present in 23% of the cases. Myometrial invasion greater than 50% had an impact on disease-free survival and local relapse-free survival (HR was 9.75 and 3.20, respectively). VLSI had an impact on distant metastasis-free survival (HR = 2.92). Advanced stages: VLSI was present in 89% of the cases. Only leiomyosarcoma type made the overall survival worse (HR = 10.54). CONCLUSIONS Vascular and lymphatic space invasion was a relevant prognostic factor in our series, with an impact on overall survival and distant metastasis-free survival in early stages. In advanced stages, VLSI had no impact on survival, but was present in 89% of cases. Myometrial invasion >50% had an impact on local relapse. Advanced stages had a more aggressive behavior, and there was a higher incidence of poor prognostic factors in these stages. Nevertheless, prospective studies are still needed on prognostic factors and on the best treatment option.

Abstract
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.

Abstract
Tumor proliferation is of important prognostic significance for several neoplasms. The very few previous studies on this parameter in vulvar carcinoma have shown contradictory results. The aim of this study was to determine the prognostic significance of tumor proliferation in vulvar carcinoma. Paraffin-embedded tissue of 74 squamous cell carcinomas of the vulva was immunostained for MIB-1, detecting Ki-67, and analyzed for staining patterns and the percentage of positive cells. There were three general staining patterns: a diffuse distribution (diffuse type), a localized staining at the infiltrating tumor border (infiltrating type), and a localized staining in basal parts of infiltrating tumor cell aggregates (basal type). The percentage of positive cells was not correlated with morphologic or clinical parameters, nor was it correlated with disease-free and overall survival. MIB-1 staining types were correlated with tumor type and grading. Tumors of diffuse and infiltrating type seemed to have more frequent lymph node metastasis (p = 0.053) and shorter disease-free survival (p = 0.076). In these tumors, overall survival time was reduced significantly (p = 0.02). In multivariate analysis, MIB-1 staining types were the most important factor for overall survival with an odds ratio of 4.73. In conclusion, distribution and not the percentage of proliferating cells is of prognostic significance in squamous cell carcinoma of the vulva.

Abstract
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.

Abstract
OBJECTIVE To clarify some anatomical controversies of the fascial structures and lymph node development of the inguinal region through an embryological study in relation to the surgical techniques of groin lymphadenectomy. METHODS Sections of the femoral triangle belonging to four fetuses whose crown-rump (CR) length ranged from 70 to 310 mm, corresponding to a developmental age of 11 and 35 weeks, were studied. RESULTS The femoral fascia is formed of one layer and is not divided into superficial and deep layers. The cribriform fascia has a morphogenetic origin different from that of the femoral fascia and it is defined by the thickening of the connective tissue filling the fossa ovalis and therefore would be more correctly named lamina cribrosa. The deep inguinal lymph nodes originate directly from the superficial lymphatic tissue located in the fossa ovalis. This last observation supports the fact that no lymph nodes are present beneath the femoral fascia distal to the lower margin of the fossa ovalis. CONCLUSIONS The results of this study, from a surgical point of view, support the technique of total or radical inguinal-femoral lymphadenectomy with preservation of the femoral fascia and, from an anatomical point of view, resolve some of the contradictory statements reported in the anatomical literature regarding morphogenesis and terminology of the structures of the Scarpa's triangle. In addition, the present study provides useful anatomic and terminological landmarks to those surgical oncologists (gynecologist, urologist, dermatologist, etc.) dealing with malignant diseases requiring groin dissection practices. In addition, it could represent a useful background for a future more precise surgical terminology which represents a vital issue for institutional studies with multiple surgeons as well as for large multi-institutional studies.

Abstract
BACKGROUND Recent advancement in recommended treatment of early stage vulvar carcinoma had emphasized the role of pathologic indications of tumor size and lymph node involvement. The purpose of this study was to identify the current mode of practice in the management of early stage vulvar carcinoma with primary disease limited to the vulva and/or the perineum. METHODS The National Cancer Data Base was accessed to examine vulvar carcinoma cases reported by 1147 hospitals that had established or were establishing American College of Surgeons Commission on Cancer programs. The periods 1988-1989 and 1993-1994 were selected for analysis. The analysis was based on the 1553 invasive nonmetastatic carcinomas (confined to the vulva and/or the perineum) for which primary lesion size and pathologic inguinal lymph node evaluation had been recorded. RESULTS There were no differences in demographic or disease characteristics between 1988-1989 and 1993-1994. Surgery alone was most often the treatment for lymph node negative patients. Radiation therapy was given as an adjunct treatment to 49% of patients with positive lymph nodes. Radiation therapy was given fairly equally to patients in all lymph node positive categories (1, 2-3, and 4 or more positive lymph nodes), with little change between the two time periods. Patients with < or = 2 cm lesions were more often treated with conservative surgery. CONCLUSIONS The major diagnostic groups and number of positive lymph nodes were confirmed to be prognostically important. Although literature on vulvar disease notes a benefit of radiation therapy for patients with more than one positive lymph node, radiation therapy was not predictive of survival for patients in this study.

Abstract
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.

Abstract
BACKGROUND Recently, invasion of vascular spaces by endometrial carcinoma has received particular attention as a prognostic factor. The goal of the current investigation was to re-examine the effect of vascular invasion on tumor recurrence and survival in patients with endometrial carcinoma. METHODS Surgical specimens from 238 patients with endometrial carcinoma were examined for the presence of vascular invasion by tumor cells. Vascular invasion was compared with clinicopathologic features and postoperative survival. Survival curves by vascular invasion were evaluated by the Kaplan-Meier method. RESULTS In a histopathologic review of 238 cases of endometrial carcinoma, 82 neoplasms demonstrated vascular invasion. Vascular invasion significantly correlated with the extension of primary tumor, depth of myometrial invasion, and histologic grade. Patients with lymph node metastasis had a significantly higher incidence of vascular invasion. Survival at 5 years for patients with vascular invasion was 73.4%. This was significantly lower than the survival rate of 91.5% for women without this finding (P < 0.001). Among patients with lymph node metastasis, 80.2% of the patients with vascular invasion survived for 5 years compared with 95.3% of the patients without vascular invasion (P < 0.05). Ten of 47 patients with no lymph node metastasis but with vascular invasion developed recurrent carcinoma. Nine of these ten patients apparently had extrapelvic recurrences. CONCLUSIONS The presence of vascular invasion is a reliable prognostic indicator. Recording of tumor recurrence pattern may lead to a better selection of patients for adjuvant systemic therapy after surgery.

Abstract
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.

Abstract
BACKGROUND This report consists of a retrospective analysis of 50 patients with primary invasive and 17 with recurrent histologically confirmed vulvar carcinoma treated with radiation therapy for locoregional disease. METHODS Of the patients with primary tumors, 13 were treated with wide local excision plus radiation therapy; 13 had radical vulvectomy followed by irradiation to the operative fields and inguinal-femoral/pelvic lymph nodes; 8 received similar postoperative radiation therapy after partial or simple vulvectomy; 16 patients had radiation therapy alone after biopsy; and 17 had recurrent tumors treated with radiation therapy alone. RESULTS In patients treated with biopsy/local excision, local tumor control was 92-100% in T1-3N0 disease, 40% in similar stages with N1-3, and 27% in recurrent tumors. Among patients treated with partial/radical vulvectomy and radiation therapy, primary tumor control was 90% in those with T1-3 tumors and any nodal stage, 33% in those with any T stage and N3 lymph nodes, and 66% in patients with recurrent tumors. The actuarial 5-year disease-free survival rates were 87% for patients with T1N0 disease, 62% for those with T2-3N0 disease, 30% for those with T1-3N1 disease, and 11% for patients with recurrent tumors; there were no long-term survivors with T4 or N2-3 disease. Four of 17 patients treated for postvulvectomy recurrent disease remain disease-free after local tumor excision and radiation therapy. In patients with T1-2 tumors treated with biopsy/wide tumor excision and radiation therapy with doses less than 50 Gy, the local tumor control was 75% (three of four patients), in contrast to 100% (13 of 13 patients) with 50.01-65 Gy. With T3-4 tumors treated with local excision and radiation therapy, tumor control occurred in none of three patients with doses less than 50 Gy and 66% (six of nine) with 50.01-65 Gy. In patients with T1-2 tumors treated with partial/radical vulvectomy and radiation therapy, local tumor control was 75% (six of eight), regardless of dose level; in T3-4 tumors, it was 67% (four of six patients) with 50-60 Gy and 86% (six of seven) with 65-70 Gy. Differences were not statistically significant. There was no significant dose response for tumor control in the inguinal-femoral lymph nodes, with doses of 50 Gy being adequate for elective treatment of nonpalpable lymph nodes and 60-70 Gy controlling tumor growth in 75-80% 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 Wide local tumor excision and radiation therapy or irradiation alone in T1-2 tumors is an alternative treatment to radical vulvectomy in controlling vulvar carcinoma, with significantly less morbidity. In comparison with reported rates for surgery alone, radiation therapy after radical vulvectomy for locally advanced tumors improves tumor control at the primary site and regional lymphatics. Indications and techniques of radiation therapy are discussed.

Abstract
There is a definite trend toward vulvar conservation and individualized management of patients with early vulvar cancer. This approach initially was used only for patients with T1 disease, but with increasing experience with conservative surgery and the integration of postoperative adjuvant radiation when appropriate, some investigators have broadened the indications to include carefully selected patients with T2 lesions. A recent literature review suggests that the local invasive recurrence rate for T1 disease is 7.2% (12 of 165) after radical local excision compared with 6.3% (23 of 365) after radical vulvectomy (P = 0.85). Surgical margins must be at least 1 cm, and the rest of the vulva must be healthy if an increased local recurrence rate is to be avoided. Local recurrences usually can be treated successfully if diagnosed early, but recurrence in the groin is usually fatal. Inguinal-femoral lymphadenectomy should be done on all patients if the primary tumor is more than 2 cm in diameter and in patients with T1 disease in whom the depth of invasion is greater than 1 mm. Separate groin incisions may be used, but pelvic and groin irradiation should be given if there is at least one large node replaced with tumor or multiple nodes containing micrometastases. Careful patient selection is critical if modified operations are used, or an increased rate of recurrence will follow.

Abstract
Vulvar carcinoma has been managed in recent years with modifications of radical vulvectomy and groin dissection. Separate groin incisions, superficial inguinal lymphadenectomy, unilateral groin dissection, and wide excision have been utilized to reduce the morbidity of treatment. In this study, the surgical management of 82 patients with vulvar squamous cell carcinoma was reviewed in order to assess morbidity and risk of recurrence. A modification of radical vulvectomy and groin dissection was employed in 67 patients, while 15 patients underwent classical en-bloc vulvar and groin dissection. Wound complications of the vulva occurred in 1 of 12 patients undergoing hemivulvectomy, in 8 of 55 undergoing radical vulvectomy, and in 7 of 15 who had en-bloc vulvar resection and groin dissection (P = 0.01). Among the 46 patients undergoing bilateral groin dissection through separate incisions, groin breakdown, lymphocyst, and lymphedema occurred in 10 (22%), 7 (15%), and 7 (15%), versus 0, 1 (7%), and 2 (13%) of the 15 who had unilateral groin dissection. Modification of vulvar resection did not increase the risk of local recurrence. Groin recurrence developed in 2 of 15 patients who underwent en-bloc groin dissection and in 1 of 46 who underwent bilateral groin dissection through separate incisions. Two of 15 who had a unilateral groin dissection recurred in the contralateral groin. The risk of recurrence as well as morbidity following modifications of radical vulvectomy with groin dissection should be considered when planning treatment.

Abstract
It has been proposed that squamous carcinoma of the vulva with 1 mm or less of stromal invasion can be treated with local resection without inguinal node dissection. A retrospective review of 255 cases of stages I and II vulvar carcinoma demonstrated 24 cases of minimally invasive carcinoma. All cases were subjected to detailed chart review and pathologic confirmation. Mean age at diagnosis was 60 years. Seven patients had a preoperative diagnosis of preinvasive disease, ten had stage I disease, and seven had stage II disease. Fifteen cases had associated vulvar carcinoma in situ. Treatment consisted of local excision in 2 patients, radical wide excision in 11, hemivulvectomy in 5, and radical vulvectomy in 6. Eleven patients had either unilateral or bilateral inguinal node dissection. Five-year life-table survival was 89%. Four patients (17%) developed recurrent dysplasia and four (17%) developed invasive recurrences. One invasive recurrence was in an inguinal node in a patient previously treated with a hemivulvectomy and negative ipsilateral superficial node dissection. Univariate analysis revealed no statistically significant associations between recurrence and age, symptom duration, margin status, location, FIGO stage, or coexisting VIN. Large areas of coexisting dysplasia and variable gross appearance make meaningful application of FIGO staging criteria difficult in lesions with minimal focal invasion. Wide excision or radical wide excision of lesions with "high-risk" VIN or those showing less than or equal to 1 mm of stromal invasion on biopsy is adequate therapy. If final pathologic review demonstrates deeper invasion, a selective lymph node dissection can be performed as a second procedure. Careful surveillance with liberal use of colposcopy and biopsies is indicated in these patients.

Abstract
Between 1956 and 1982, 139 patients were surgically treated in the Netherlands Cancer Institute because of a squamous cell carcinoma of the vulva. Eighty-nine of these patients underwent radical vulvectomy and inguinal lymph-node dissection. Five-year survival rates were 91% for stage I, 85% for stage II, 64% for stage III and 33% in stage IV cases. The fact that 5 year survival rates between the group of patients with a more extensive surgical treatment (i.e., inguinal lymph node dissection) and the group of patients only being treated by a vulvar operation were equal, is a remarkable result. Postoperative complication rates were, in conformity with results found elsewhere, high. Only 25% of the patients did not have any early complication at all. The most important early complication was found to be wound infection (52%). Late complications were mostly miction problems (24%) and pelvic relaxation, resulting in cystocele, rectocele and/or descensus uteri (26%). Patients who were treated only by a vulvar operation had significantly less late complications (P = 0.027). The majority of recurrences were observed in the first 2 postoperative years. Patients with a pelvic relapse or with distant metastases could in no case be treated successfully. Inguinal relapses, however, could only be treated with success when primary treatment of the groin had not been given before. Complete remissions were very often accomplished in case of vulvar relapse and second, third, or fourth relapses on the vulva. Ten percent of all the patients still alive 5 years after primary treatment had a relapse as yet, or more likely, a second vulvar carcinoma.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Although the standard therapy of vulvar carcinoma remains radical surgery, this approach is accompanied by significant postoperative morbidity and psychological adjustment. Radical hemi-vulvectomy and ipsilateral superficial groin node dissection are increasingly used for patients with "early" or "microinvasive" disease. Two patients with an "early" vulvar carcinoma were treated conservatively and later developed recurrent disease. Despite further surgery and radiotherapy, both patients eventually died of disease. The case histories are described and the pertinent literature is discussed.

Abstract
Four hundred fifteen patients who had invasive carcinoma of the vulva were treated with primary surgery from July 1, 1955, through June 30, 1989. Three hundred seventy-six (90%) of the patients had squamous carcinoma. Two hundred fourteen patients (52%) had radical vulvectomy with inguinofemoral lymphadenectomy. Twenty-four patients (6%) underwent radical vulvectomy with pelvic exenteration for advanced disease, and 55 patients (13%) had nonradical operations. The remaining 122 patients (29%) underwent radical vulvectomy, inguinofemoral lymphadenectomy, and pelvic lymphadenectomy. The primary morbidity was associated with lymphedema (8.6%) and groin wound breakdown (54%). No intraoperative deaths occurred among the 415 patients treated surgically, but there were 17 deaths (4%) within 28 days of operation. The absolute 5-year survival rate was 85% in patients with negative inguinofemoral lymph nodes and 39% when these lymph nodes were positive for metastatic carcinoma. The overall absolute 5-year survival rate was 67%.

Abstract
Limited resection of some vulvar cancers may provide cure rates equivalent to those obtained with radical vulvectomy and bilateral inguinal node dissection. Rapid recovery, fewer complications, and better functional result have been described as advantages to less extensive procedures. Since 1978, 32 patients with invasive squamous cell cancer of the vulva (depth greater than 1 mm) and clinically negative inguinal lymph nodes underwent radical wide excisions as primary therapy. Mean age at diagnosis was 61 years. Seventeen patients had T1 and 15 had T2 tumors. Resection of the primary lesion was tailored to lesion location and size, and dissection was carried to the deep perineal fascia. Twenty-two patients had unilateral superficial inguinal lymph node dissections, five with midline lesions had bilateral superficial dissections, and five had node samplings which included deep inguinal nodes. Depth of invasion ranged from 1.5 to 13.0 mm. Mean largest lesion dimension was 23 mm. Five-year lifetable survival for the entire group was 84%. Univariate analysis of potential prognostic variables showed no significant recurrence or survival differences for patient age (P = 0.56), symptom duration (P = 0.57), FIGO stage (P = 0.67), tumor grade (P = 0.20), tumor location (P = 0.26), depth of invasion (P = 0.56), or resection margin status (P = 0.63). Thirty-one percent of patients had perioperative complications, and 16% developed delayed complications. Mean hospital stay was 10 days. Three patients (10%) developed new or recurrent vulvar disease and underwent additional therapy. None have died of disease, although one is alive with persistent tumor. Radical wide excision and selective inguinal lymphadenectomy constitute a reasonable alternative to radical vulvectomy with bilateral inguinal node dissections for squamous tumors clinically limited to the vulva. Outcome may not be strongly influenced by lesion size or depth of invasion.

Abstract
One hundred and thirty-five patients with squamous carcinoma of the vulva were treated at UCLA and City of Hope Medical Centers between 1957 and 1985. Sixty-two cases were stage I, 48 stage II, 18 stage III, and 7 stage IV. Twenty-one patients developed a local vulvar recurrence after primary radical resection. Ninety-one patients had a surgical tumor-free margin greater than or equal to 8 mm on tissue section and none had a local vulvar recurrence. Forty-four patients had a margin less than 8 mm; 21 had a local recurrence and 23 did not (P less than 0.0001). Of the 23 patients with a margin less than 8 mm who did not recur locally, 14 remained free of disease, and 9 had either advanced disease, declining health, or short follow-up. Depth of invasion is associated with local recurrence, with a 9.1-mm reference value correctly predicting outcome in 81.5% of cases. Increasing tumor thickness is associated with local recurrence, with a 10-mm reference value predictive of 90% non-recurrence and 33% recurrences. A pushing border pattern is less likely to recur than an infiltrative growth pattern. Lymph-vascular space invasion has a combined predictive accuracy of 81.5%. Increasing keratin and greater than 10 mitoses per 10 high-power fields correlate with local recurrence. Neither clinical tumor size nor coexisting benign vulvar pathology correlates with local recurrence. Fourteen of twenty-one patients with vulvar recurrence died of metastatic disease, four died of intercurrent disease, and three were alive at 32, 68, and 157 months, with 16 recurring in less than 1 year. Surgical margin is the most powerful predictor of local vulvar recurrence. Combining factors in a stepwise logistical regression does not significantly improve this predictive value. Accounting for specimen preparation and fixation, a 1-cm tumor-free surgical margin on the vulva results in a high rate of local control, whereas a margin less than 8 mm is associated with a 50% chance of recurrence.

Abstract
Six patients with superficially invasive squamous carcinoma of the vagina are described. All patients meet recently proposed criteria for the diagnosis of microinvasive vaginal carcinoma. The depth of invasion measured from the surface was less than 2.5 mm. There was no lymph-vascular space involvement. The invasive foci arose within a field of carcinoma in situ. Five of these six patients had previously been treated for invasive cervical cancer with pelvic radiation from 82 to 246 months before the diagnosis of vaginal carcinoma. All but one patient had the carcinoma confined to the upper one-third of the vagina. All patients were treated with a single vaginal radium application following vaginectomy. One of these six patients expired from recurrent vaginal cancer 35 months following diagnosis. During the same 17-year period, 17 other cases of Stage I epidermoid cancer of the vagina were treated which did not meet the above criteria for microinvasion. There were no statistically significant differences between these two groups with regard to age at diagnosis, history of cervical cancer, hysterectomy, or pelvic radiation or in survival. Additional experience with early vaginal carcinoma is needed before microinvasive carcinoma of the vagina should be accepted as a distinct clinical entity.

Abstract
Clinical staging, tumor size, histologic differentiation, cytologic grading, depth of stromal invasion, and vascular channel involvement by tumor cells were studied in 42 patients with invasive squamous cell carcinoma of the vulva who were treated with radical vulvectomy and inguinal-femoral lymphadenectomy. All parameters were found to correlate well in predicting groin node metastasis. Cytological grading was found to be more significant compared to histologic grading in regard to nodal metastasis (P less than 0.02). No patient with cytologic or histologic grade 1 tumor and less than 5 mm stromal invasion was found to have nodal metastasis.

Abstract
Treatment for squamous cell carcinoma of the vulva remains surgical, the standard procedure being radical vulvectomy and bilateral inguinal lymphadenectomy. There has been recent interest in refining histopathologic prognostic factors that would be highly predictive of regional lymph node metastases, recurrences, and survival. With such factors have come new innovative approaches to the management and treatment of minimally invasive carcinomas, regional nodal disease, and advanced lesions. These modifications from standard therapy could result in less morbidity, disfigurement, and hospitalization while not compromising survival.

Abstract
Early invasive stage I squamous cell carcinoma of the vulva treated with radical vulvectomy and bilateral inguinofemoral lymphadenectomy rarely recurs, particularly when the lymph nodes contain no metastatic tumor. Primary radical surgery in this patient utilized separate groin incisions, and recurrent tumor developed in the tissue bridge between the groin scar and the vulva. Reexploration showed numerous inguinofemoral nodes to subseqently contain recurrent carcinoma. Literature regarding early, "microinvasive," squamous cell carcinoma of the vulva is reviewed.

Abstract
Based on 124 patients with squamous cell carcinoma of the vulva treated at the 1. Frauenklinik der Universität München from 1971 to 1980, the influence of pretreatment characteristics on survival was assessed. The patients underwent a simple vulvectomy with local and inguinal irradiation. All histologic specimens were worked up in the same manner, and all available specimens were reverified. Follow-up lasted from at least 2 up to 12 years post-treatment, with no dropouts. Using the Cox model of multivariate analysis, five pretreatment characteristics were found to most strongly influence survival: age, dissociated tumor growth, lymphatic spread, tumor thickness, and ulceration. These pretreatment characteristics were implemented in an algorithm for survival-oriented prognostic forecasting. Survival data as predicted from this algorithm correlated well with observed survival data. The validity of these prognostic factors needs to be examined in further studies using comparable patient populations and study designs.

Abstract
Prognostic parameters were evaluated in 22 patients with small (less than or equal to 2 cm) superficially invasive (less than 5 mm) squamous cell carcinoma of the vulva. Primary surgery included radical vulvectomy with bilateral superficial and deep inguinal lymph node dissection in 11 patients, and wide local excision with ipsilateral superficial inguinal lymph node dissection in 11 patients. Of the 22 patients studied, only 2 (9%) had lymph node metastases. Both patients had a single positive ipsilateral superficial inguinal node. Perineural invasion was strongly associated with lymph node metastases (P less than 0.01). In this group of patients, grade, depth of invasion, lymph-vascular space invasion, and lymphoplasmacytic infiltration were not predictive of lymph node metastases (P greater than 0.05). Two patients initially treated with wide local excision and ipsilateral superficial inguinal lymph node dissection developed recurrent vulvar neoplasia on the contralateral vulva, and both were successfully retreated by wide local excision. All patients are presently alive and well with no evidence of disease. None of the histomorphologic parameters studied were predictive of tumor recurrence. These data suggest that wide local excision with ipsilateral superficial inguinal lymphadenectomy is effective in the treatment of patients with small, superficially invasive carcinomas of the vulva.

Abstract
The results of treatment in the department of 607 patients with invasive squamous cell carcinoma of the vulva between 1952 and 1980 is described and analyzed. The absolute 5-year cure rate in these patients was 60.3%. Particular attention was given to lymph node status (TNM system) in the analysis of the last 141 patients treated. The absolute 5-year survival rate was 67% for the N0-N1 patients and 43% for the N2-N3 patients. Patients were treated uniformly by means of electrosurgical operation and postactinic irradiation of the inguinal lymph nodes. Operative lymphadenectomy was performed only in 5% of cases when the diameter of inguinal lymph nodes was greater than 2 cm. This simple surgical technique, in combination with irradiation of inguinal lymph nodes, gives excellent results and avoids the complications associated with inguinofemoral lymphadenectomy. Owing to its combination of electrosurgical operation of the vulva and irradiation of the inguinal regions as a standard procedure, the treatment involves extremely low strain on the patient and is almost free of complications. This seems to be particularly important as the results of our treatment are not less satisfactory than those of more aggressive procedures.

Abstract
Various studies assess the significance of depth of invasion as an important prognostic factor in squamous cell carcinoma of the vulva. However, methodologic problems exist with regard to the measurement points. While the deepest point of invasion can be measured accurately, the upper reference point is arbitrarily chosen. The goal of the present study was to identify the method of measurement and the threshold value, allowing the clearest prognostic differentiation between groups of patients with vulvar carcinoma. The study involved 124 patients treated between 1971 and 1980, who had received identical treatment (simple vulvectomy followed by local and inguinal irradiation) and identical histopathologic workup (large-scale sections). Beginning with the deepest point of tumor invasion, comparative measurement was carried out with three different points of reference: to the basement of the most superficial dermal papilla (method A), to the surface of the tumor (method B), and to the basement membrane of the deepest rete ridge (method C). The data were used to determine differences in specified end points. The results and conclusions are as follows: (1) The morphometrically determined degree of tumor invasion had prognostic significance. (2) Measurement of tumor thickness (method B) prognostically differentiates patient groups better than measurement of invasion from the most superficially lying epithelial papilla (method A), if classified into tumors up to and over 0.5 cm. (3) Patients with superficial invasive vulvar carcinomas up to 0.5 cm can be further prognostically differentiated into two groups, when measuring depth of invasion from the deepest rete ridge (method C), and classifying into tumors up to and over 0.3 cm.

Abstract
Genital tumors represent a special group requiring effective and curative treatment while functional and cosmetic demands require tissue sparing techniques. For these reasons, micrographic surgery is indicated. Over the past 5 years we have treated 24 such patients utilizing standard techniques for micrographic surgery. The patient population included twenty male and four female patients with ages ranging from 27 to 80 years. Histologically confirmed diagnoses included squamous cell carcinoma, Bowen's disease, verrucous carcinoma, basal cell carcinoma, Paget's disease, and leiomyosarcoma. These were located on the penis, scrotum, perineum, and buttocks. Seven of these patients were considered to have recurrent tumors. Preexisting conditions existed in 6 patients, including balantis xerotica obliterans, trauma, decubitus ulcer, and hidradenitis suppurativa. All surgery was performed under local anesthesia in the cutaneous surgery unit. Average pretreatment tumor size was 2.0 X 1.9 cm. Average postoperative defect size was 4.5 X 3.7 cm. Tumors were excised with an average of three stages and 18 sections. Most defects (65%) were allowed to heal by secondary intention, five (21%) were closed primarily, and three were referred for closure. After surgery five patients developed metastases in their regional lymphatic system. No patients developed local recurrence. Micrographic surgery is a most useful treatment modality in patients with genital tumors for control of local disease. However, patients with squamous cell carcinoma should be considered for elective regional lymph node biopsy and/or dissection in conjunction with micrographically controlled excision of the primary tumor.

Abstract
The en bloc dissection approach to many cancers of the reproductive tract needs re-evaluation in light of recent data. The mechanisms by which one or more malignant cells leaves the primary lesion and are then deposited as a viable focus at distant sites, is also in need of study. The hypothesis is put forth that metastases to regional lymph nodes occurs from the primary lesion as an embolic event leaving the intervening normal tissue bridge at low risk for disease. Indeed, these viable cells, which have the potential for becoming a metastatic focus, may fall victim to the patient's host defense mechanisms. In light of this, recent clinical experience with cancer of the cervix, vulva, and breast, is outlined with particular emphasis on more conservative surgical techniques and their success. A plea is made for individualization of surgical therapy, especially with early lesions affording ample opportunities for preservation of function, body image, and improved quality of life.

Abstract
In a histopathological review of 171 cases of endometrial adenocarcinoma, 42 neoplasms demonstrated lymphatic and/or vascular invasion. This finding was significantly correlated with depth of myometrial involvement and stage of disease at operation. Tumour cell type, and histological grade were correlated to a much lesser extent, whilst the patient's age bore no relation. Prognosis was significantly poorer in patients whose adenocarcinomas had invaded lymphatic and/or vascular spaces compared to those whose neoplasms had not. These observations emphasize the importance of considering lymphatic/vascular invasion in staging endometrial adenocarcinomas.
