14. Staging
IA Tumor confined to the vulva or perineum, ≤ 2cm in size
with stromal invasion ≤ 1mm, negative nodes
IB Tumor confined to the vulva or perineum, > 2cm in size or with
stromal invasion > 1mm, negative nodes
II Tumor of any size with adjacent spread (1/3 lower
urethra, 1/3 lower vagina, anus), negative nodes
15. Staging
IIIA Tumor of any size with positive inguino-femoral lymph
nodes
(i) 1 lymph node metastasis ≥ 5 mm
(ii) 1-2 lymph node metastasis(es) < 5 mm
IIIB (i) 2 or more lymph nodes metastases ≥ 5 mm
(ii) 3 or more lymph nodes metastases < 5 mm
IIIC Positive node(s) with extracapsular spread
16. Staging
IVA (i) Tumor invades other regional structures (2/3
upper urethra, 2/3 upper vagina), bladder mucosa, rectal
mucosa, or fixed to pelvic bone
(ii) Fixed or ulcerated inguino-femoral lymph nodes
IVB Any distant metastasis including pelvic lymph
nodes
17. Prognosis
Lymph nodes status
Lesion size
Histologic grade, tumor thickness, depth of stromal invasion, lymph-
vascular space involvement, tumor ploidy
Stage I – 79%
Stage II – 59%
Stage III – 43%
Stage IV – 13%
21. Stage Ia – Microinvasive T1a
Wide Local excision – deep upto dermis
Stage Ib & II – Early vulval cancer
Radical local excision plus Ipsilateral groin node
dissection
- 1 cm negative margin
- Extending up to inferior fascia of urogenital diaphragm
- Separate incision technique
Treatment
22. Treatment
Midline lesions
Anterior – clitoris sparing surgery – 8mm margin
Periclitoral lesion in young pt – small field RT with
concomitant chemosensitization
small lesion – 5000 cGy external radiation
f/b biopsy
23. Treatment
Stage II involving adjacent srtucture
Radical vulvectomy or radical local excision Plus
LN Dissection
Advanced disease
Surgery plus RT
plus
concomitant chemo
28. Closure of large defects
Small defects – primary closure without tension
Large – left open to granulate
Full thickness skin flap – rhomboid or mons pubis flap
Myocutaneous flap – gracialis
Tensior fascia lata myocutaneous graft
29. Management of LN
> 2 cm diameter
> 1 mm invasion
Surgery – trt of choice
Bilateral dissection - midline lesions, clitoris, post forchet
- unilateral bulky LN / multiple microscopic
LN
Bulky LN – debulking
Fixed unresectable LN - chemoradiation
30. Sentinal Lymph node biopsy
Criteria
1) unifocal primary tumour of 4 cm or less in diameter with >
1 mm invasion
2) no obvious metastatic disease on physical
examination/imaging
31. Postop management
Ambulation on day 1 or 2
DVT prevention
Subcutaneous heparin
pneumatic calf compression
Frequent dressing
Suction drainage of each side of the groin
Sitz bath
32. Early Postoperative Complications
Groin wound infection, necrosis, breakdown
En bloc operation – 53-85%
Separate-incision approach – 44%
UTI
Lymphocyst
DVT
Pulmonary embolism
MI
Hemorrhage
33. Late Complications
Chronic lymphedema
Recurrent lymphagitis or cellulitis
Usually responds to oral antibiotics
SUI
Introital stenosis
Femoral hernia (uncommon)
Depression, altered body image and sexual dysfunction
Pubic osteomylitis
Fistula
34. Recurrent Vulvar cancer
≥ 3 LN - 2/3 of vulvar cancer recur within first 2 years from initial
Tx.
Local recurrence
Margin status
Closer than 0.8cm -> 50% recur
Primary lesion larger than 4cm in diameter
Ipsilateral lymphovascular space invasion
Deep invasive tumour
Tx.
Additional surgery with myocutaneous graft
External beam therapy + interstitial needles
with chemotherapy
35. Regional and Distant Recurrence
Difficult
Poor prognosis
Radiation
Chemotherapy
Bleomycin and methotrexate & lomustine
Bleomycin and mitomycin C
Cisplatin, vincristine & paclitaxel
Response
Usually disappointing
Long-term survival is very uncommon
36. Role of Radiation Therapy
primary vulval ca.
Advanced disease
LN meta – microscopic, gross
Possible roles for RTx.
Involved or close surgical margin
Small primary tumor - primary Tx.,
Particularly clitoral or periclitoral lesion
37. Melanoma
Rare
Incidence : 0.1-0.19/100,000women
Second most common of vulvar malignancy
Postmenopausal white women
No symptoms (most)
Itching, bleeding, groin mass
Labia minora, clitoris
Vulvar nevi are junctional, precursor lesion to melanoma; thus,
should be removed
38. Histopathology
Mucosal lentiginous melanoma
Flat freckle, quite extensive, superficial
Superficial spreading melanoma
Most common, superficial
Nodular melanoma
Most aggressive, raised lesion
Penetrate deeply
Metastasize widely
¼ of cases of melanomas
Macroscopically amelanotic -> spread early
42. Bartholin Gland Carcinoma
Rare
Postmenopausal
Premenopausal
Honan’s criteria
The tumor is in the correct anatomic position
The tumor is located deep in the labium majus
The overlying skin is intact
There is some recognizable normal gland present
43. Bartholin Gland Carcinoma
Signs and Symptoms
Vulvar mass or perineal pain
10% of patients may be mistaken for benign cysts or
abscesses
Treatment
Radical vulvectomy with bilateral groin and pelvic LN
dissection
Fixed, involves adjacent structures-> postop radiation
and chemotherapy is preferable
