What are the protective factors against ovarian cancer?
Definition
OCP, sterilisation and breast feeding.
Term
If ovarian CA becomes metastatic, where is likely to be the first site affected?
Definition
Omental cake forming on omentum.
May also spread to peritoneum/abdominal organ surfaces and to pleural cavities with ascites.
Term
What causes ascites in ovarian cancer?
Definition
Due to breakdown of the peritoneal barrier to extra-cellular fluid, lymph blockage and protein lost into ascites causing increased oncotic pressure.
Term
Describe the stages for ovarian cancer progression
Definition
•Stage 1 - Limited to one/both ovaries only
•Stage 2 - Extension into pelvic region (e.g. uterine/tubal/broad ligament surface)
•Stage 3 - Extension beyond pelvis onto abdominal organs - Most common presentation
•Stage 4 - Distant Metastases
Term
What symptoms would lead you to a differential diagnosis of ovarian cancer?
Definition
Abdominal/pelvic pain, bloating and feeling full, urinary symptoms and constitutional e.g fatigue and weight loss.
Term
What signs would lead you to a differential diagnosis of ovarian cancer?
Definition
Abdominal distension, palpable abdominal/pelvic mass, shifting dullness and pleural effusion.
Term
What investigations would you consider for suspected ovarian CA?
Definition
Surgery, radiology for staging and CA-125 marker in order to track progression once diagnosis made.
Term
What surgical treatment would be considered for ovarian CA?
Definition
Hysterectomy
Bowel resection, depending on spread
Interval debulking (chemo, surgery, chemo)
Term
What chemotherapy should be considered for the treatment of ovarian cancer?
Definition
Carboplatin
Reduced dose in renal failure.
2nd line for relapsed- same if platinum sensitive or CAELYX if platinum resistant.
Term
When should radiotherapy be considered in the treatment of ovarian cancer?
Definition
Only palliatively
Term
What targeted therapies are there avilable for the treatment of ovarian CA?
Definition
VEGF antagonists.
Term
What has caused a drop in incidence of cervical CA in the UK?
Definition
Screening programmes
Term
In which age group is cervical cancer the most common?
Definition
Spread evenly in all age groups above 25YO.
Term
What factors increas your risk of developing cervical CA?
Definition
Number of sexual partners (HPV), smoking OCP, HIV/immunosuppression.
Term
What cervical area is more prone to dysplasia?
Definition
Cervical transformation zone
Term
What changes occurs at the cervical transformation zone during puberty?
Definition
Area of cervical canal exerts to cervical os and undergoes squamous metaplasia due to the acidity of the vagina.
Term
What is the most common cause of cervical cancer?
Definition
HPV 16 and 18, over 70%.
Mucosa-mucosa transmission usually cleared in 1-2 years.
Term
What is cervical intra-epithelial neoplasia?
Definition
Term for cervical dysplasia before progression to neoplasia
Term

Definition
Squamous carcinoma >80%
Adenocarcinoma- most of the other 20%
Term
If not picked up in screening, what presentation would lead you to the differential diagnosis of cervical cancer?
