  Purpose

RATIONALE: S-adenosyl-L-methionine may help relieve hot flashes in women based upon its ability to potentially modulate serotonin.

PURPOSE: This phase II trial is studying the side effects and how well s-adenosyl-L-methionine works in treating hot flashes in women with a history of breast cancer or those who do not wish to take estrogen due to a perceived increased risk of breast cancer.

Primary Outcome Measures:
  • Percent of Baseline in Average Hot Flash Activity (Score and Frequency) [ Time Frame: From baseline to week 7 ] [ Designated as safety issue: No ]
    Hot flash score was defined as the number of mild hot flashes for the week plus two times the number of moderate hot flashes plus three times the number of severe hot flashes plus four times the number of very severe hot flashes. Hot flash frequency was defined as the average number of hot flashes per day for each week. Week 7 percent of baseline was calculated. The reduction in hot flash score and frequency can be calculated by subtracting the week 7 percent of baseline from 100 percent.


Secondary Outcome Measures:
  • Change From Baseline in Self-assessment Items [ Time Frame: End of study ] [ Designated as safety issue: No ]
  • Adverse Event Grade Incidence [ Time Frame: End of study ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: Arm I
The first week of the study is a baseline week where data are being collected but study agent is not being taken. Patients then receive oral s-adenosyl-L-methionine, 400 mg, once daily on days 8-14 and twice daily on days 15-49 in the absence of unacceptable toxicity.
Drug: S-adenosyl-L-methionine disulfate p-toluene-sulfonate

Detailed Description:

OBJECTIVES:

I. To evaluate the impact of SAMe on hot flash scores in women with a history of breast cancer or women who do not wish to take estrogen therapy for fear of increased risk of breast cancer.

II. To evaluate the toxicity of SAMe in this study population. III. To evaluate the effect of SAMe using quality-of-life (QOL) measures.

OUTLINE:

During the first week, participants will complete a daily, prospective hot flash diary and complete baseline questionnaires and will not be taking any study medication. After this baseline week, participants will receive oral s-adenosyl-L-methionine, 400 mg, once daily on days 8-14 and twice daily on days 15-49 in the absence of unacceptable toxicity.

Criteria

Inclusion Criteria:
