Investigating pain levels in younger vs older women during breast cancer treatment

Self-Reported Pain and Nadir White Blood Cell/Absolute Neutrophil Count in Women 45 and Under Compared to Older Women Receiving Pegfilgrastim (or Biosimilar Substitution) While Undergoing Chemotherapy for Non-Metastatic Breast Cancer

Observational Wake Forest University Health Sciences · NCT04174742

This study is trying to see if younger women feel more pain than older women during chemotherapy for breast cancer while they receive a specific treatment.

What this trial studies

This observational study aims to assess pain levels reported by younger women compared to older women undergoing chemotherapy for non-metastatic breast cancer while receiving pegfilgrastim or its biosimilar. Participants will self-report their pain using the ESAS pain scores over a week following each dose of treatment. Blood samples will be collected to measure white blood cell counts, allowing for a comparison between self-reported pain and actual blood measurements. The study will categorize subjects into two age groups: 45 years or younger and over 45, to identify any differences in pain perception and blood count correlations based on age.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 and older with invasive breast cancer undergoing chemotherapy and pegfilgrastim treatment.

Not a fit: Patients with uncontrolled medical or psychiatric conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of pain management in breast cancer treatment, potentially leading to tailored therapies based on age.

How similar studies have performed: While similar studies have explored pain management in cancer treatment, this specific age-based comparison is relatively novel.
