A Novel Approach Utilizing Organ Specific Age Proteomics

Investigating Cellular Senescence and Organ Aging in Breast Cancer Patients Undergoing Adjuvant Chemotherapy: A Novel Approach Utilizing Organ Specific Age Proteomics

This study compares changes in P16INK4A expression and plasma proteomic signatures of specific organ age pre- and post-chemotherapy in women treated with adjuvant chemotherapy for early-stage breast cancer. It aims to determine if biological and accelerated immune aging, assessed using T cells from peripheral blood, represents aging in different organs.

Patients receiving chemotherapy, especially adjuvant regimens that include anthracyclines and taxanes, often experience late development of cardiac toxicity, functional loss, and cognitive decline. Comparing baseline characteristics with organ aging before therapy might identify patients at the highest risk for chemotherapy complications. For example, this is clinically significant for patients whose therapy includes taxanes or other drugs known to cause peripheral neuropathy. Identifying aging in the neurological or vascular systems before treatment might lead to changes in regimens.

Determining accelerated aging in specific organs allows for investigating interventions to mitigate organ damage. For instance, identifying patients at the highest risk of cardiac aging after treatment could lead to testing the effects of exercise, senolytics, and other strategies to reduce the risk of long-term heart disease.

Study Overview

Detailed Description

Chemotherapy has revolutionized cancer treatment, significantly improving relapse-free and survival rates for many cancers. However, these advances have come with a downside, and nowhere is this more evident than in childhood cancer. Despite the significant advances in the curability of most childhood cancers, up to 20% of patients die of comorbidity and secondary cancers by the age of 35 years.

Recent research shows that a plasma proteomic measure of protein abundance and expression can provide a" global" proteomic signature that accurately predicts chronologic age in the general population. It was shown that accelerated organ aging conferred a 20-50% higher mortality risk, and this was pronounced for those with accelerated cardiac and brain aging.

Previous studies have shown that p16INK4a, a robust biomarker of cell senescence measured in peripheral blood T cells, rises dramatically and likely irreversibly after adjuvant therapy for breast cancer. For anthracycline regimens, p16INK4a changes suggest 10 to 20 years of accelerated aging shortly after treatment. Additionally, in murine models, changes in P16INK4A are seen in all organs as mice age, but not all organs age at the same rate.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Chemotherapy
40 patients with early-stage breast cancer whose treatment plan includes adjuvant or neoadjuvant chemotherapy.
Blood samples will be collected at two time points, plasma samples will be aliquoted, and T cells will be separated and expression of p16INK4a mRNA in peripheral blood T-lymphocytes will be determined
Blood samples will be collected at two time points, plasma samples will be aliquoted, and organ-specific protein signatures assessment will be determined.
Control
20 patients with early-stage breast cancer whose treatment plan does not includeadjuvant or neoadjuvant chemotherapy.
Blood samples will be collected at two time points, plasma samples will be aliquoted, and T cells will be separated and expression of p16INK4a mRNA in peripheral blood T-lymphocytes will be determined
Blood samples will be collected at two time points, plasma samples will be aliquoted, and organ-specific protein signatures assessment will be determined.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
p16INK4a level changes over time
Time Frame: Up to 8 months
The p16INK4a level will be determined from collected samples in each group. For the Chemotherapy Group, samples will be drawn before chemotherapy and 6-8 months after chemotherapy. For the Control Group, samples will be collected after diagnosis and again 6-8 months later. The differences will be tabulated.
Up to 8 months
Organ-specific protein expression change over time
Time Frame: Up to 8 months
Organ-specific protein levels will be determined from collected samples in each group. For the Chemotherapy Group, samples will be drawn before chemotherapy and 6-8 months after chemotherapy. For the Control Group, samples will be collected after diagnosis and again 6-8 months later. The differences will be tabulated in grams per deciliter (g/dL)
Up to 8 months
