Gynaecology Oncology 2 Flashcards
What is an epithelial tumours of the ovary?
derived from epithelium covering the ovary
most common in postmenopausal women
What are the different types of epithelial tumours of the ovary?
from most common to least common
- serious cyst adenoma or adenocarcinoma
- endometroid carcinoma
- mutinous cystadenoma
- clear cell carcinoma
- brenner tumour
What are the germ call tumours of the ovary?
teratoma or dermoid cyst
- common benign tumour in young premenopausal women
- may contain hair and teeth
- common bilateral
dysgerminoma - rare but most common ovarian malignancy in younger women
What is premalignant vulval cancer?
vulval intraepithelial neoplasia (VIN), presence of atypical cells in vulval epithelium
more common in women 35-55
associated with HPV, CIN, cigarette smoking, chronic immunosuppression
What is differentiated type VIN?
rare
associated with lichen sclerosis
seen in older women
risk of progression to cancer
What are the RFs for vulval cancer?
normally arise de novo
VIN premalignant
associated with lichen sclerosis, immunosuppression, smoking, paget’s disease of the vulva
What are the symptoms of vulval cancer?
pruritus, bleeding or discharge
malignancy often presents late
ulcer or mass most commonly on labia major or clitoris
inguinal lymph nodes may be enlarged, hard and immobile
How does vulval cancer spread?
Vulval carcinoma spreads locally
Spreads via lymph drainage of vulva
What are investigations for vulval cancer?
biopsy to establish diagnosis and histyological
assess fitness for surgery - CXR, ECG, FBC, UEs, cross match blood
How is vulval cancer managed?
Biopsy then wide local excision with separate groin node dissection, bilateral unless tumour >2cm from midline
Radiotherapy if lymph node involvement
What can be used for pain relief in cancer?
analgesic ladder
co-analgeics - antidepressants, steroids, cytotoxic may be used
opioid analgesia can be patient controlled
alternative therapies
What can be used N+V in cancer treatment?
Poss opiates, metabolic causes (e.g. uraemia), vagal stimulation (e.g. bowel
distension) or psychological factors
Antiemetics = anticholinergics, antihistamines, dopamine antagonists or 5HT-
3 antagonists
What can be done for high vaginal bleeding in cancer treatment?
High dose progesterones may be useful
Radiotherapy used if not used before
What is ascites and bowel obstruction a sign of?
advanced ovarian carcinoma
How is ascites and bowel obstruction managed?
- ascites best drained slowly by repeated paracentesis
- obstruction managed at home
- partial obstruction –> metaclopramide used with stool softeners with enemas for constipation and trial of dexamethasone to reduce tissue oedema
- complete obstruction –> cyclizine and ondansetron for N&V, hyoscine for spasm
- encourage eating and drinking small amount
- stents can be inserted in acute obstruction
- terminal distress - manage sensitively
