Late menopause is a risk factor for what three cancers
- Endometrial Cancer
- Ovarian Cancer
- Breast Cancer
Endometrial cancer is classically found in post-menopausal women. True or false
True. around 25% cases occur before menopause though
Risk factors for endometrial cancer
- Obesity
- Nulliparity
- Early menarche
- Late menopause
- Unopposed oestrogen
- Addition of progesteron to oestrogen (eg in HRT) reduces the risk
- Diabetes mellitus
- Tamoxifen
- Polycystic Ovarian Syndrome
- Hereditary non-polyposis colorectal carcinoma
What are some protective factors for endometrial cancer
- Combined oral contraceptive pill
- Smoking
Features of endometrial cancer
- Postmenopausal bleeding
- Premenopausal women may have a change in intermenstrual bleeding
- Pain and discharge are unusual features
Investigations for endometrial cancer
- >= 55 yrs presenting with postmenopauusal bleeding needs to be referred using suspected cancer pathway
- First-line investigation: Trans-vaginal ultrasound
- Hysteroscopy with endometrial biopsy
Normal endometrial thickness that has high negative predictive value
- < 4mm
Management of endometrial cancer
Localised disease
- Total abdominal hysterectomy with bilateral salpingo-oophorectomy
- High risk patients have post-op radiotherapy
- Progesteron therpay considered in frail elderly women not suitable for surgery
Salpingo = fallopian tube
hysterectomy = uterus
Nulliparity is a risk factor for which three cancers
- Ovarian cancer
- Endometrial cancer
- Breast cancer
Epidemiology and prognosis of ovarian cancer
- 5th most common malignancy in women
- Peak age of incidence = 60
- Poor prognosis due to late diagnosis
What is the most common origin for ovarian cancers and what sub-type makes up for 70-80% of this sub-type
- 90% epithelial cell in origin
- Of the 90%, 70-80% are serous carcinomas (low or high grade)
Risk factors for ovarian cancer
- Family History
- Mutations
- BRCA1 and BRCA2
- Increased ovulations
- Early menarche
- Late menopause
- Nulliparity
What factor reduces the risk of ovarian cancer
Combined oral contraceptive pill
Reduces number of ovulations (as does having many pregnancies)
Clinical features of ovarian cancer
Notoriously vague
- Abdominal distension
- Abdominal bloating
- Abdominal and pelvic pain
- Urinary syptoms (urgency etc)
- Early satiety
- Diarrhoea
Investigations for ovarian cancer
- CA125
- If ≥ 35 IU/mL -> urgent ultrasound of abdomen and pelvis
- CA125 should NOT be used to screen for ovariuan cancer in asymptomatic women
- Ultrasound
- Abdomen and pelvis
What other conditions usually show a raised CA125
- Ovarian Cancer
- Endometriosis
- Menstruation
- Benign ovarian cysts
Diagnosis of ovarian cancer
- Diagnostic laparotomy
How is ovarian cancer staged
- Stage 1: Confined to ovaries
- Stage 2: Local spread within the pelvis
- Stage 3: spread beyond the pelvis to the abdomen
Haematological and lymphatic routes are common but these occur after spread to local pelvis.
- Lymphatic spread: para-aortic lymph node
- Haem spread: liver
Management of ovarian cancer
Combination:
- Surgery
- Platinum-based chemotherapy
Prognosis of ovarian cancer
- 80% have advanced disease at presentation
- All stage 5-year survival is 46%
Mode of action of COCP
Inhibits ovulation
Mode of action of progesterone-only pill (excluding desogesterel)
Thickens cervical mucus
Mode of action of desogesterel-only pill
- Primary: Inhibit ovulation
- Also: Thickens cervical mucus
Mode of action for injectable contraceptive (medroxyprogesterone acetate)
- Primary: Inhibits ovulation
- Also: thickens cervical mucus
