Cole Relaxation Frequency as a Prognostic Parameter for Breast Cancer

Area of Science:

• Oncology
• Biophysics
• Medical Diagnostics

Background:

• Previous research established Cole relaxation frequency for classifying breast cancer vs. benign tissue.
• A retrospective analysis of a prior study cohort was conducted.

Purpose of the Study:

• To investigate the prognostic potential of Cole relaxation frequency for breast cancer patient outcomes.
• To correlate Cole relaxation frequency with cancer recurrence and metastasis status.

Main Methods:

• Utilized health system cancer registry data for retrospective outcome classification.
• Categorized patient outcomes into nonrecurrent (NR), recurrent with no metastasis (RNM), and recurrent with metastasis (RM).
• Performed multivariate analysis to assess the association between Cole relaxation frequency and time-cancer-free.

Main Results:

• Cole relaxation frequency demonstrated a clear trend from nonrecurrent to recurrent with metastasis.
• Increased Cole relaxation frequency significantly correlated with poorer patient outcomes.
• Multivariate analysis revealed significant associations (P-values 0.0001-0.0047) with time-cancer-free.

Conclusions:

• Cole relaxation frequency is a feasible prognostic parameter for breast cancer.
• This finding supports its use in larger, prospective studies for predicting patient prognosis.
