Clinical Trial Summary

This pilot research trial studies telomere length in predicting toxicity in older patients with stage III-IV colorectal cancer undergoing chemotherapy. Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in deoxyribonucleic acid (DNA) and predict how well patients will respond to treatment.


Clinical Trial Description

PRIMARY OBJECTIVES:

I. To determine the relationship between pre-treatment telomere length (TL) and rate of grade 3 or higher adverse events occurring on front line leucovorin calcium, fluorouracil, and oxaliplatin (FOLFOX)-based chemotherapy among patients over the age of 70 with early stage or metastatic colorectal cancer (CRC).

SECONDARY OBJECTIVES:

I. To evaluate the impact of the FOLFOX-based chemotherapy treatment on peripheral blood lymphocyte telomere length.

II. To evaluate the association between pre-treatment geriatric assessment tools scores, telomere length, and the incidence of chemotherapy related adverse events among older early stage or metastatic CRC patients.

TERTIARY OBJECTIVES:

I. To evaluate the association between pre-treatment levels of serum interleukin-6 (IL-6), C-reactive protein (CRP) and D-dimer and incidence of chemotherapy related adverse events.

II. To evaluate the correlation between pre-treatment telomere length, levels of other biomarkers of aging (IL6, CRP, D-dimer), and rates of adverse events with FOLFOX-based chemotherapy.

OUTLINE:

Patients undergo blood sample collection for analysis via real-time polymerase chain reaction (PCR) at baseline, 3 months, and 6 months.

After completion of study, patients are followed up every 3 months for up to 2 years. ;
