Brief summary
This is a randomized, single-site pilot study incorporating one control group. This research involves an exercise group and a non-exercise group (control group). The patients who are in the exercise group will be enrolled in the Dallas County Women's Adventure Boot Camp. This will require them to undergo exercise training 3 times per week, under the direction of an experienced personal trainer in a group setting. All Boot Camp personal trainers are trained in basic cardiac life support (CPR) and are trained to watch for any signs or symptoms associated with a poor exercise response. The investigators hypothesize that randomizing women to a supervised exercise program of core conditioning, muscular/circuit training, and short distance running administered during neoadjuvant chemotherapy for breast cancer can be performed. Patients will continue on study as they are undergoing neoadjuvant chemotherapy for their breast cancer. This will be about 4 - 6 months.
Detailed description
The exercise protocol will consist of activities including walking/running up to a mile, calisthenics (jumping jacks, short relays, rapid punches) and light (no greater than 5 pounds) weight lifting. The patients who do not receive the exercise program will be allowed to do what they would normally do during their neoadjuvant chemotherapy. They are allowed to engage in their own exercise regimens and diet modifications. Subjects will receive the chemotherapy as directed by their physicians, and then undergo surgery as planned. Randomization will occur by drawing cards entitled exercise or control from an envelope and then assigning the patient to this group.
Interventions
BEHAVIORALExercise
Five woman undergoing neoadjuvant chemotherapy for breast cancer will be randomized to an exercise protocol supervised by an experienced personal trainer. The exercise will be administered three times a week for the 4-6 months of neoadjuvant chemotherapy. The exercise protocol will consist of activities including walking/running up to a mile, calisthenics, and light weightlifting.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Ki-67 index | post-neoadjuvant chemotherapy; ~ 4-6 months from treatment start | Ki-67 has significant value for predicting survival and recurrence risk in breast cancer. A recent study reveals that patients with a post-neoadjuvant chemotherapy Ki-67 index of less than 1.0% had significantly improved survivals when compared to patients with a Ki-67 index \> 1.0% |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pathologic complete response rate | post-neoadjuvant chemotherapy; ~ 4-6 months from treatment start | The rate of pathologic complete response at the primary tumor site from the standard 15% to \>20%. |
