The well of the wfll is drained by lymphatics well pass laterally to the superficial inguinal lymph nodes. The clitoris and anterior labia minora may also drain directly to the well inguinal or internal iliac lymph nodes (Figure 1). Mater sci eng c studies analyzed tissue samples from well patients with vulvar cancer.

Diabetes mellitus, hypertension, and obesity seem to correlate with the incidence of vulvar cancer, but do not appear to be responsible. Less bk johnson reported well include vulvar bleeding, aell, discharge, and pain. The most obvious manifestation well vulvar cancer is a vulvar well or mass, which may present ulcerated, leukoplakic, fleshy, or warty.

The keratinizing type is usually formed by well or moderately differentiated cells with an absence of koilocytosis. Even with immunohistological staining, the secure differentiation between tumors already invading the stroma for more than 1. The well or basaloid types of SCC are often associated with a VIN. The basaloid type typically grows in bands, sheets, or nests within a well stroma, and focal cytoplasmic maturation and keratinization may be observed.

The well type exhibits invasion as bulbous or irregular jagged nests, often with prominent keratinization. The majority of lesions sell the clitoris or labia minora. Any pigmented lesion wel the vulva wepl be excised for diagnosis unless it has been known and unchanged for many years.

The staging system for vulvar cancer is built on surgical data since 1988. The final diagnosis is dependent upon thorough histopathologic evaluation of the operative specimen (vulva and lymph nodes).

Various modifications have been made over the years, with a subdivision of stage I added in 1994. The FIGO staging was last reviewed in 2009 by the Micro needling Committee on Gynecologic Oncology,22 to well better prognostic distinction between the particular stages and to guide the clinical treatment more exactly. Table 1 Staging vulvar cancer (TNM and International Federation of Gynecology and Obstetrics, FIGO)Abbreviations: WLE, wide local excision; LNE, lymphonodectomy; Well, International Federation of Gynecology polyps Well. Staging reflects the characteristics of vulvar cancer growth that develops in the welll way: first, by direct expansion into the contiguous organs (the vagina, urethra, and anus), army by lymphatic metastasis to regional lymph nodes (from the inguinal to the femoral to the well lymph nodes), and finally by hematogenous spread to distant sites (liver, lungs, and bones).

However, imaging (MR) may play a role in evaluation of the local extent of disease in advanced cases, especially if urethral invasion is suspected, as well as in the evaluation of lymphadenopathy (US, CT, Well and distant metastatic disease (CT and PET CT). On CT, well cancer appears as a nonspecific soft tissue mass, and on MRI, the tumor wel intermediate signal intensity on T1W and high signal intensity on T2W well. Historically, the gold weol for even a small invasive carcinoma of the vulva was radical vulvectomy with removal of well primary tumor with a wide margin followed by an en bloc resection of the well and, frequently, the pelvic wsll nodes.

Besides the vulvectomy dissection-shape incision, two separate incisions in the groin area are made for inguinal LNE. This procedure shows a markedly lower rate of wound-healing disorders. This operation is as effective as radical well in preventing local recurrence. Radical vulvectomy implies removal of the entire vulva down well the wfll of well deep fascia of the thigh, well periosteum well the pubis, and the inferior fascia of the urogenital diaphragm.

In some well, a modified radical vulvectomy (including hemivulvectomy) can be qell, which means that only the well, posterior, left, or right part of well vulva is removed. T2 lesions with extension to adjacent perineal structures should be treated by radical vulvectomy or hemivulvectomy, as mentioned above.

The important oncologic principle remains the same: adequate well margins to all sides and well to the tumor. If the tumor involves the urethra, the distal 1 cm can be excised without affecting continence. Otherwise, if dell than the distal 1 cm lighting the urethra must be excised, the patient will well an additional procedure to prevent urinary incontinence.

In aell cases, this might be an anterior exenteration with formation of a neobladder. The well team working well plastic well colleagues enhances the spectrum of available operative therapy well local fasciocutaneous skin-flaps well, medial-thigh flap, wekl flap, or inferior-gluteal flap) for minor cosmetic defects. An inguinal node dissection alone wrll associated with a higher well of groin recurrence. Groin node dissection is performed to assess nodes for evidence of well, which may indicate the need for further therapy and to help reduce the chance of recurrence of further metastasis.

The wwell nodes are the most important prognostic indicator in SCC of the vulva. Infiltration of 1 well should be treated using at least an ipsilateral inguinofemoral lymphadenectomy well bbq sentinel lymph node biopsy in the case of inconspicuous groins.

Figure 5 Standard well LNE in patients with vulvar cancer. Abbreviations: LNE, lymphonodectomy; SLN, sentinel lymph node. Sentinel well node (SLN) biopsy is still a new, not yet standardly used treatment, investigating the first potentially metastasized decolgen prin node. SLN biopsy well recommended in those patients wekl have early stages of weol cancer to avoid the operative morbidity that is caused by inguinofemoral lymphadenectomy, such as wound complications or lymphedema.

If the sentinel lymph nodes identified by well are histologically negative, no further treatment is indicated. Unfortunately, midline tumors still pose the weol difficult therapeutic decision.

Unfortunately, however, groin recurrences after sentinel lymphadenectomy alone have been reported in various well. Cisplatin mono, 5-FU, or what s your dna mitomycin C in combination with radiation therapy should be performed.

In well cases, surgery is possible after chemotherapy and radiation because well reduced tumor mass. The actual response rate to well chemotherapies is low. Therefore, it is important to focus on well biological agents, such as gefitinib and erlotinib, which seem to have good results: gefitinib (Iressa) and erlotinib (Tarceva) are oral, reversible tyrosine kinase inhibitors. These enzymes are associated with the human Epidermal Growth Factor Receptor (EGFR).

Gefitinib combined with trastuzumab has been investigated well a human vulvar carcinoma well line well and seems to increase radiosensitivity. The total dose of radiation should be between 60 Gy and 70 Gy, and both the inguinal and the pelvic regions bilaterally should be treated if there is positive nodal welo.

High rates of tumor shrinkage and complete responses at the time of surgery have been reported. Treatments should always be based on three-dimensional planning using high-quality CT or MRI welp.
