Brief summary
The overall purpose of this study is to investigate whether younger subjects report pain with pegfilgrastim (or biosimilar substitution) more often and/or at higher levels (greater intensity) than older subjects.This study will be carried out throughout the course of your chemotherapy treatment, which will be prescribed by your study doctor. Participation in this study will not affect your cancer treatment.
Detailed description
This study will measure pain using ESAS self-reported pain scores over the course of one week following each dose of pegfilgrastim (or biosimilar substitution). At the end of that week, blood will be drawn from each subject to directly measure the WBC/ANC, which can then be compared to self-reported pain and evaluated for any correlation. Finally, subjects will be divided into two groups by age: 45 years or younger, and over 45 to look for any differences in pain or WBC/ANC measurements based on age.
Interventions
It works by increasing neutrophil migration to counteract cytotoxicity. It is commonly administered to patients receiving chemotherapy for breast cancer treatment. It has been shown to significantly reduce the incidence of neutropenic fever, although without statistically significant impact on overall survival.

Histological or cytological confirmation of invasive breast cancer. 5. Planned to undergo adjuvant or neoadjuvant chemotherapy treatment for invasive breast cancer AND pegfilgrastim (or biosimilar substitution) treatment for neutropenic prophylaxis. 6. Ability to read and understand the English and/or Spanish language 7. As determined by the enrolling physician, ability of the subject to understand and comply with study procedures for the entire length of the study
Exclusion criteria
Subjects meeting any of the criteria below may not participate in the study: 1. Uncontrolled intercurrent illness/medical condition or psychiatric illness/social situations that would limit compliance with study requirements as determined by the investigator 2. Have previously received chemotherapy or radiation other than the first cycle of the planned adjuvant or neoadjuvant chemotherapy as indicated in Inclusion #5 3. Taking chronic narcotics, as determined by treating physician 4. Diagnosis of distant metastatic breast cancer 5. Diagnosis of a chronic pain syndrome (e.g. fibromyalgia, severe osteoarthritis, etc.) 6. A baseline ESAS pain score of greater than 8.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Frequency of pain | approx 7 months | investigate whether younger patients report pegfilgrastim (or biosimilar substitution)-induced pain with greater frequency than older patients. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Intensity of pain | approx 7 months | investigate whether younger patients report pegfilgrastim (or biosimilar substitution)-induced pain at a higher intensity than older patients. |
| White Blood Cell/Absolute Neutrophil Count (WBC/ANC) | On day 7 of each pegfilgrastim or biosimilar substitution cycle (28 day cycle, approx 4-6 cycles) through study completion (one week after last administration of pegfilgrastim or biosimilar substitution) | compare WBC/ANC count nadir between younger and older patients receiving pegfilgrastim (or biosimilar substitution). |
