Q

What are the main Rx options for breast cancer?

A
  1. Surgery - WLE + RTx or mastectomy
  2. Medical adjuvant Rx
    - Endocrine Rx - if ER/PR +

    - Targeted Rx - if HER2 receptor +

Endocrine - Oestrogen receptor antagonist (Tamoxifen) pre- and post-menopausal women (5-10 yr course, increased risk of VTE, uterine Ca) or aromatase inhibitors (post-menopausal women only)

Targeted - Transtuzumab (Herceptin), 5 year course

Q

How can menstrual regulation be Rx in PCOS?

A
  1. Lifestyle factors - weight loss 5-10% can restore ovulatory cycles
  2. Metformin - can improve cycles
  3. Contraception - COCP (+endometrial Ca protection as increased risk with amenorrhoea), progesterone only

Aim for >4 periods/year (unless on contraception)

Q

How can hyperandrogenism in PCOS be Rx?

A

1st line - cosmetic options
2nd line - COCP - increases SHBG, decreasing testosterone
3rd line - antiandrogen (spirnolactone, finasteride)

Q

How can fertility be Rx in PCOS?

A

Risk of infertility in PCOS increases >30 yo & BMI > 30
1st line = weight loss & lifestyle intervention
2nd line = pharmacological - metformin (if primary setting), clomiphene (if specialist setting) - increased fertility if used together

If 35 yo and if BMI >30

17
Q

What is the clinical presentation of ectopic pregnancy?

A
  1. Amenorrhoea (6-8 wks - longer suggests other cause)
  2. Pelvic pain - often first symptom, can be unilateral

Abnormal pelvic bleeding in 1st trimester
Adnexal tenderness and cervical excitation

18
Q

What are signs of ruptured ectopic pregnancy?

A

Signs of peritonitis
Shoulder tip pain
Haemodynamically unstable, LOC, dizziness
Dysuria, painful defaecation (due to haemperitonium)

19
Q

What Ix would be ordered in suspected ectopic pregnancy?

A
  1. BhCG
  2. Transvaginal U/S - intrauterine sac not seen in +B-hCG, blood in pouch of douglas, may see ovarian/fallopian mass
  3. Serum progesteron - decreased level sensitive indicator
  4. Diagnostic laparoscopy (gold standard diagnosis)
20
Q

What is the Rx of ectopic pregnancy?

A
  1. Surgical most common due to risk of rupture and haemorrphage - if adnexal mass >3.5cm, haemodynamically unstable, foetal heart activity, b-hCG high, moderate-severe pelvic pain, intraperitoneal bleeding
  2. Medical
    - Large single dose of methotrexate - rupture/haemorrphage must be less likely, willing for regular follow-up, stable, mild-no pelvic pain or tenderness, adnexal mass
21
Q

What HRT consideration must be made in female with hysterectomy vs. intact uterus?

A

Must provide cyclical progesterone with oestrogen if intact uterus to reduce risk of endometrial cancer

If hysterectomy oestrogen alone is fine

22
Q

What are the C/I for HRT?

A
VTE
IHD/CVD or high risk 
Unexplained vaginal bleeding - needs Ix 
Hx breast cancer, endometrial cancer
Active liver disease 
>60 yo or >10 yrs since menopause
23
Q

What considerations, assessments & discussions with patient do you make before prescribing HRT?

A
  1. Confirm menopause and that they are experiencing symptoms
  2. Age - generally avoid commencing >60 yo
  3. Consider if any C/I to HRT and if so consider other symptomatic agents
  4. Mammogram - before or 3/12 after commencement
  5. Assessment of CV risk (lipids, HbA1c, examination)
  6. Discussion of risks vs. benefits
  7. Side effects
24
Q

What are the current general recommendations for HRT?

A

All women with premature or early menopause should be prescribed HRT unless C/I

Appropriate for women with osteoporosis but should not be prescribed solely for Rx or prevention

Not appropriate for cardioprotection and avoid in those with established or high risk

Generally don’t commence >60 yo

Avoid therapy > 4 - 5 yrs

Review patient risk/benefit annually

25
Q

Risks

  • Increased risk of VTE but does not increase CVD risk in healthy women
  • Small increased risk of ovarian Ca
  • Risk of endometrial Ca but eliminated if cyclic progesterone used
26

A

Peri- or post-menopausal women who are experiencing menopausal symptoms (within 5 yrs of last period)

All women with premature or early menopause to prevent osteoporosis
