Aromasin´┐Ż Non-Interventional Study Of Early Invasive Breast Cancer Patients In China [Recruiting]
Aromasin« (Exemestane) was approved in China for adjuvant treatment of postmenopausal women with estrogen receptor (ER) positive early invasive breast cancer who have received 2-3 years of tamoxifen & are switched to Aromasin« for completion of a total of 5 consecutive years of adjuvant hormonal therapy by State Food and Drug Administration (SFDA) with clinical trial waive. While Aromasin« has been used in China for adjuvant therapy of breast cancer since then, there is currently lack of systematic collection and analysis for the efficacy and safety data of Aromasin« adjuvant setting in Chinese population. The Aromasin« Non-Interventional Study is being proposed to collect data systematically and to assess the efficacy and safety of Aromasin┬« adjuvant setting in Chinese population.

Exemestane and Celecoxib in Postmenopausal Women at High Risk for Breast Cancer [Completed]
The primary goal of this 5-year study is to determine whether exemestane alone or in combination with celecoxib decreases breast tissue density in healthy postmenopausal women at high risk for breast cancer. Dense breast tissue seen on mammography has been linked to an increased risk of breast cancer. The study will also examine the effects of exemestane and celecoxib on bone density, blood hormone levels and quality of life. Exemestane, approved by the Food and Drug Administration for treating postmenopausal women with breast cancer, lowers the amount of estrogen in the body. Celecoxib, approved for treating arthritis pain and for reducing the number or colon polyps in an inherited syndrome, is an anti-inflammatory drug. Half of the women in the study will receive exemestane alone and half will receive exemestane and celecoxib together. In December 2004, the arm using exemestane and celecoxib was closed to accrual Postmenopausal women who are at increased risk for developing invasive breast cancer may be eligible to participate. Candidates are screened with breast cancer risk assessment, medical history and physical examination, blood tests, review of medical records, if needed, breast biopsy, and dual energy x-ray absorptiometry (DEXA) scan to assess bone density. For the DEXA scan, the subject lies still on a table for about 30 minutes while the spine and hip are scanned using a small amount of radiation. Participants take exemestane in pill form once a day for 2 years. They also take calcium and vitamin D pills daily to help protect bone health. They are followed in the clinic during the course of the study to determine the amount of drug taken and any side effects, and for the following tests and procedures:

- Medical evaluation and blood tests at after 1 and 3 months on study drugs

- Medical evaluation at 6 months

- Breast biopsy at screening and then at 12 months

- dual-emission x-ray absorptiometry (DEXA) scan of the spine, mammogram and routine

blood tests before starting study drugs and then yearly for 5 years.

Aromasin review by 57 year old female patient

Overall rating:  
Effectiveness:   Considerably Effective
Side effects:   No Side Effects
Treatment Info
Condition / reason:   Breast Cancer
Dosage & duration:   5mg taken 1/day for the period of 3 years
Other conditions:   under-active thyroid
Other drugs taken:   Synthroid
Reported Results
Benefits:   Aromasin's treatment benefits are unknown. I have not had a reoccurance of breast cancer while on the drug, though unsure we can attribute that with the drug treatment itself. Perhaps there are other positive health-related items coming into play, such as exerciase and eating habits. Not aware of any side effects or adverse reactions. Drug is very expensive, however.
Side effects:   As mentioned above, I have not had any side effects from Aromasin other than hot flashes and night sweats. These may be due to menopause rather than the treatment itself. The hot flashes have been relatively mild and can be controlled, for the most part, by limiting or removing all alcoholic beverages.
Comments:   After breast cancer treatment of chemo. and radiation I was put on Tamoxifen for several years, about 5 years. After Tamoxifen, it was recommended that I start taking Aromasin, which I have done for about 3 years. My doctor said it is not known how long women should be on Aromasin and still receeve a benefit from taking the drug.


Aromasin review by 58 year old female patient

Overall rating:  
Effectiveness:   Highly Effective
Side effects:   Moderate Side Effects
Treatment Info
Condition / reason:   eostrogen-positive breast cancer
Dosage & duration:   25mg taken daily for the period of 4 years
Other conditions:   high blood pressure
Other drugs taken:   various blood pressure medications
Reported Results
Benefits:   During the 4 years so far [out of 5], I have had no recurrance of the tumour and no additional tumours have been detected by ultra-sound, mammogram, and twice-yearly check-ups. Perhaps the greatest benefit is the gradual reduction in stress experienced as a result of my on-going stabilised condition after a lumpectomy.
Side effects:   I had some initial swelling of my hip, knee and ankle joints in the morning which slowly subsided during the day. The medication also aggravated the hot-flushes of the menopause, making them initially frequent and copious, and on-going for the treatment duration so far - tho with reduced frequency now in Year 4. I also experience considerable thirst.
Comments:   I was put on Aromasin after 6 months on Tamoxifen because I suffered debilitating muscle cramps on Tamoxifen as well as joint problems and extreme hot flushes. Aromasin has been kinder, and so far I have taken it daily for 4 years out of an initial 5. It may be prescribed beyond 5 years, I'm not sure. It has relatively slight side effects now but in the first 6 months I was conscious of its effects on my body - not intolerable by any means, just noticable.
