Brief summary

The purpose of this study is to determine if patient education can affect patient reported bone pain in breast cancer patients receiving chemotherapy and pegfilgrastim.

Detailed description

In this study, the effect of patient education on reported bone pain in breast cancer patients receiving adjuvant or neoadjuvant chemotherapy and pegfilgrastim will be investigated. Each patient will receive adjuvant or neoadjuvant chemotherapy with pegfilgrastim prophylaxis, beginning in the first cycle and continuing throughout the study period. The study period for this study is the first 4 cycles of chemotherapy. participants can be planning to receive regimens with \> 4 cycles, but data will only be collected for the first 4 cycles. The choice of chemotherapy regimen (agent, dose, and schedule) is at the discretion of the treating physician. Commercially available pegfilgrastim will be administered according to US Prescribing Information and is considered background therapy.

Participant flow

Recruitment details

This study was conducted at 48 centers in the United States. Patients with stage I to III breast cancer planning to receive standard neoadjuvant or adjuvant chemotherapy regimens with pegfilgrastim support for at least 4 cycles were included. The first participant enrolled on 17 January 2013 and the last participant enrolled on 04 September 2014.

Pre-assignment details

Participants were randomized in a 1:1 ratio to receive 1 of 2 educational DVDs: general chemotherapy side effects education DVD (GE-DVD) or bone pain education DVD (BP-DVD). Participants remained on study for the first 4 chemotherapy cycles. End of study occurred 30 days after administration of pegfilgrastim in the fourth cycle of chemotherapy.

Time frame: Days 1 to 5 during cycle 1.
