Gynae cancers Flashcards
(34 cards)
What are the groups of ovarian cancers?
- Epithelial (70%)
- Germ cell (20%)
- Sex cord/ stomal cell (10%)
What are the benign epithelial cancers?
- Serous cystadenoma
- Mucinous cystadenoma
What are the malignant epithelial cancers?
- Endometriod
- Clear cell
What are the benign germ cell tumous?
- Mature teratoma (dermoid cyst)
- Dysgerminoma
What are the malignant germ cell tumours?
- Immature teratoma
- Choriocarcinoma
What are the sex cord/ stomal tumours?
- Fibroma (Meig’s syndrome)
- Granulosa-theca cell tumour
- Leydig-sertoli cell tumour
What is Meig’s syndrome?
- Right sided pleural effusion
- Fibroma
- Ascites
What is a common tumour that metastasises to the ovaries?
Gastric/ colonic tumours, causing Krukenberg tumour formation in the ovary
Mucin-producing signet-ring cells
What are the stages of ovarian cancer?
FIGO
1. In the ovaries
2. In the pelvis
3. In the abdominal cavity (including regional lymph nodes)
4. Metastases outside the abdomenal cavity
What is the management for stage I ovarian cancer?
Hysterectomy and bilateral salpingo-oophorectomy + adjuvant chemo
(If fertility wishes to be preserved and they’re stage Ia, unilateral oophorectomy)
What is the management for stage 2 ovarian cancer?
Debulking surgery + neo/adjuvant chemo
What is the managment for stage 3 ovarian cancer?
Debulking surgery + neo/adjuvant chemo + Bevacizumab
If surgery can’t be performed, platinum based chemo and symptomatic management (eg. ascitic drainage, laxatives)
What is the management for stage 4 ovarian cancer?
Same as stage 3, palliative care more likely
What is the first line chemo regimen for ovarian cancer?
Combined carboplatin + paclitaxel every 3 weeks for 6 cycles
What are the investigations once treatment for ovarian cancer is complete?
CT
CA125 - tends to rise in recurrence, if cancer recurs treat as palliative
What is the mechanism of carboplatin?
Causes cross-linkage of DNA stands leading to cell cycle arrest
Calculated using GFR
What is the mechanism of Paclitaxel?
Causes microtubular damage preventing replication and cell division
Pre-emptive steroids given to reduce hypersensitivity reactions and side effects
Causes total loss of body hair
What is the mechanism of Bevacizumab?
Monoclonal antibody against VEG-F inhibiting angiogenesis
What is the management of vulval cancer?
Excision
- 15mm margin
- Large lesions can be shrunk by neoadjuvant radiotherapy (often + chemotherapy)
When is full inguinofemoral lymphadenectomy done in vulval cancers?
If the lesion has a depth of >4cm
How can full iliofemoral lymphadenectomy be avoided in vulval cancers?
Sentinal node biopsy
- Dye and radioactive nucleotide injected into the vulval tumour to identify senital node
- If sential node positive, full IFL
What can be used instead of surgery for vulval cancers?
If patient is unfit, radical radiotherapy
What are the complications of inguinofemoral lymphadenectomy?
- Poor wound healing
- Infection
- VTE
- Chronic lymphoedema
When is adjuvant radiotherapy indicated for vulval cancers?
If excision margins are close or in the presence of two or more groin node mets
