Brief Summary
Significant Aromatase Inhibitor-associated toxicity, affects as many as 50% of patients with breast cancer leading to early discontinuation of this life-saving cancer treatment. No effective pharmacologic therapy has yet been identified for management of these symptoms, as many patients do not experience relief of symptoms with analgesic therapy. Vitamin B12, whether as injection or oral forms, has been used as a naturopathic product to provide relief for joint pain caused by arthritis. This effect has not been studied in the setting of Aromatase Inhibitor-Associated Musculoskeletal Symptoms (AIMSS).

Outcome Measures
Primary Outcomes (1)
Percentage Change in Average Joint Pain in Women With Aromatase Inhibitor-associated Musculoskeletal Symptoms (AIMSS) Compared to Baseline as Measured by the Brief Pain Inventory Short Form (BPI-SF).
The Brief Pain Inventory - Short Form (BPI- SF) average pain score used. This item has a scale of 0 to 10 with 0 indicating "No pain" and 10 indicating "Pain as bad as you can imagine" We expect at least 20% improvement in BPI-SF pain scores. Participants were asked to rate worst pain an average pain within the last 24 hours.
Baseline and 90 days (+/- 10 days)
Secondary Outcomes (3)
Percentage Change in Worst Pain at the End of Treatment .
Baseline and 90 days (+/- 10 days)
Percentage Change in Functional Quality of Life as Measured by the Functional Assessment of Cancer Therapy-Endocrine Scale (FACT-ES)
Baseline and 90 days (+/- 10 days)
Percentage Change of Serum Levels of Vitamin B12, C-reactive Protein (CRP), Homoscyteine (HCys) and Methylmalonic Acid (MMA).
Baseline and at 90 days (+/- 10 days)
Study Arms (1)
Arm I
EXPERIMENTALOral Vitamin B12
Interventions
Vitamin B12 2500 micrograms sublingually per day over the course of 90 days (+/- 10 days)
