Long-term Risks • Breast Cancer • Endometrial cancer, If unopposed • Venous thrombosis • Gallbladder disease • ?Ovarian cancer • ?cardiovascular disease
HERSHERS HERS the Heart and Estrogen/progestin Replacement Study 1998 • Placebo controlled study • Secondary prevention/established CHD • Average age 66.3 years • Increase HDL/decreased LDL • Non-sig increase CHD at 1 year • Non-sig decrease CHD at 4 years
HERS • Early harm and late benefit • Needed primary prevention study
Women’s Health Initiative2002 • Prempo ( not available in uk) • Premarin 0.625mg and 2.5mg MPA • 8,506 ASYMPTOMATIC WOMEN • Age 50-79 yrs, average 63 yrs. • 23% above 70 yrs • Not primary prevention • 40% were on statins/ antihypertensives • 7.7% had had Coronary thrombosis

WHI cont • Decrease in Hip and Vertebral fracture and Colonic Cancer • CVD only increased in women who started HRT 20 Yrs after menopause • Non-sig REDUCTION if started within 10 yrs
WHI Oestrogen only arm 2004 • CHD Down 42% • Breast cancer Down 28% • Colorectal caner Down 41% • CVD 0% Change • Deaths Down 27%
Million Women Study 2003 • Oxford • Case controlled • Observational • Diverse range of HRT (Questionnaire) • Age 50-64 (mean age 57) • Attending for mammogram in UK (Bias)
MWS • 30% increase in breast cancer in women taking unopposed oestrogen • Risk starts at 1 year and disappears after Rx stopped. • 9364 had breast cancer, 2224 were excluded? Why.
Risk of Breast Cancer • 12 per 1000 after 15 years HRT • Comparable to risk of; alcohol,obesity,having no children, having late first pregnancy or late menopause
Current advice on HRT • Use for symptoms or low bone density • NOT secondary prevention of CVD • Do not commence after 60yrs • In symptomatic women ? Prevention CHD and Alzheimer’s • ? reduce Progesterone to 7 days
Duration of use • Clock starts ticking at 50 yrs • Asymptomatic or <1yr 18% • 1-5yrs 56% • 5+ yrs 26% • Still symptomatic in 60s 10% • May be reluctant to stop at 5yrs • Wean off gradually
Assessment for HRTHistory • LMP/Bleeding pattern • Document symptoms • Need for contraception • Hysterectomy • PMH VTE/CHD/CVA • Liver disease • FH Breast Cancer/ Osteoporosis
Examination • Blood Pressure • Weight • PV if abnormal bleeding • Cervical Smear If due • Mammogram as part of national screening programme only • FSH if hysterectomy or irregular bleed, <45yrs, if contraception an issue.
Opportunistic Health Promotion • Smoking • Alcohol • Diet- Low Cholesterol and High Calcium • Weight bearing exercise • Stress • Chronic disease management
Types of HRT • Tablets • Patches • Implants • Nasal spray • Gel • Vaginal ring • Pessary • Vaginal cream

Lack of libido • Tibolone (Livial) • Testosterone implant • TAH and BSO • FADS, female androgen deficiency • Tired, loss of libido, headache, depression
