Blood biomarkers for cardiac damage during and after radiotherapy for esophageal cancer: A prospective cohort study
Purpose
The aim of this study was to test the hypothesis that the levels of High Sensitive Troponin T (HS-TNT) and N-terminal Brain Natriuretic Peptide (NT-ProBNP) increase after radiation therapy in a dose dependent way and are predictive for clinical cardiac events.
Materials and Methods
Blood samples during and after radiotherapy of 87 esophageal cancer patients were analysed regarding the course of HS-TNT and NT-ProBNP levels and their relationship with clinical toxicity endpoints and radiation dose volume parameters.
Results
HS-TNT values at the end of treatment correlated with the mean heart dose (p = 0.02), whereas the rise of NT-ProBNP correlated with the mean lung dose (p = 0.01). Furthermore, the course of both HS-TNT (p < 0.001) and NT-ProBNP (p < 0.01) levels were significantly different for patients who developed new cardiac events as opposed to those without new cardiac events.
Conclusion
Significant correlations were found for both biomarkers with radiation dose and clinical toxicity endpoints after treatment. Therefore, these markers might be of additional value in NTCP models for cardiac events and might help us unravelling the mechanisms behind these toxicity endpoints.
期刊介绍：
Radiotherapy and Oncology publishes papers describing original research as well as review articles. It covers areas of interest relating to radiation oncology. This includes: clinical radiotherapy, combined modality treatment, translational studies, epidemiological outcomes, imaging, dosimetry, and radiation therapy planning, experimental work in radiobiology, chemobiology, hyperthermia and tumour biology, as well as data science in radiation oncology and physics aspects relevant to oncology.Papers on more general aspects of interest to the radiation oncologist including chemotherapy, surgery and immunology are also published.
