Has she been on steroids, or any signs of Cushings Syndrome? You need to look for other causes - check serum Calcium to exclude hyperparathyroidism, TSH to exclude hyperthyroidism, 25-hydroxyvitamin D to exclude vitamin D deficiency and 24 hr urinary calcium to assess malabsorption and renal abnormalities. Be sure she is taking 1200-1500 mg Ca and Vit D supplementation, 800 IU/d and weight bearing exercise. F/U BMD in 2 years. If she is truly taking her Fosamax, she may be a nonresponder, you could check a biochemical marker of bone resorption, if it is elevated significantly that could prove useful information. There is heterogeneity and markers often do not provide a clear-cut answer, but it may give you a reason to try another bisphosphonate, i.e. residronate. Teriparatide (human recombinant PTH) can be used in women who have failed or are intolerant to previous osteoporosis therapy, but it is quite expensive. You could consider Evista, clinical trials show decreased incidence of breast CA on women on it for 3 years.

I haven't seen many postmenopausal women in the last 4 years, so I'm asking for some advice.

I have a 58 yo G3P3 with history of breast cancer and endometrial cancer that has been taking fosamax 70mg/wk for her 'prevention of osteoporosis.' She has had a mastectomy and TVH/BSO in the past.

This was the first I had seen her, so I ordered a bone density scan since she hadn't had one in several years. Her T score was -2.6.

Obviously, she is not a candidate for estrogen therapy.

Now that she is clearly osteoporotic, what other options do I have in her treatment?

Thanks,

Glen

The American Medical Association is no longer designating CME hours for AMA Category II CME credit. However, physicians themselves may self designate learning activities as Category II CME credit hours if they feel it is of sufficient educational merit and meets the formal definitions of continuing medical education. OBGYN.net believes these interaction in this forum meets these criteria. For further information see the AMA web site.
