Abstract

Purpose: The present study was performed to investigate the association of prostate cancer radiotherapy with inflammaging, a condition characterized by the elevation of inflammatory blood parameters that significantly increases the susceptibility to the occurrence or progression of age-related conditions.

Patients and methods: A total of 306 patients treated with curative radiotherapy (RT) for prostate cancer were enrolled into the prospective study. Aging-related inflammatory parameters including C-reactive protein (CRP), albumin, fibrinogen, cholesterol, platelet-to-lymphocyte ratio (PLR), and neutrophil-to-lymphocyte ratio (NLR) were analyzed before and at the end of RT, and 3 and 15 months after completion of the RT. Statistical analysis was performed using non-parametric variance analysis.

Results: Overall variance analysis showed a significant influence of RT on all inflammatory parameters (p < 0.001) with the exception of CRP (p = 0.498). Pairwise analysis revealed a significant elevation of fibrinogen (p = 0.041), NLR (p < 0.001), and PLR levels (p < 0.001) as well as a significant decrease of albumin (p < 0.001) and cholesterol levels (p < 0.001) during the RT course. After completion of RT, a significant recovery was detected for NLR, PLR, albumin and cholesterol. However, 15 months after RT, PLR, fibrinogen, and cholesterol remained significantly lower when compared to the baseline (p < 0.001).

Conclusion: Our results indicate that radiation therapy triggers chronic inflammatory processes that could contribute to the development, acceleration or worsening of age-related alterations and conditions. Further investigations to estimate the long-term consequences of curative radiation therapy on clinical manifestations of aging are warranted.

期刊介绍: The WORLD JOURNAL OF UROLOGY conveys regularly the essential results of urological research and their practical and clinical relevance to a broad audience of urologists in research and clinical practice. In order to guarantee a balanced program, articles are published to reflect the developments in all fields of urology on an internationally advanced level. Each issue treats a main topic in review articles of invited international experts. Free papers are unrelated articles to the main topic.
