Comment on: clinical value of circulating tumor DNA for patients with epithelial ovarian cancer
Circulating tumor DNA
Authors
Abstract
The purpose of this letter is to highlight the potential clinical effects and importance of circulating tumor cells and circulating tumor DNA (ctDNA) in oncology patients undergoing PRP (Platelet-Rich Plasma) therapy. ctDNA and circulating tumor cells are considered important biomarkers of disease progression and minimal residual disease in solid tumors. With the increasing use of PRP and exosome-based therapies in cosmetic and regenerative medicine in recent years, the theoretical risk of contamination with tumor material from current or past malignancies, despite these biological products being derived from the patient’s own blood, has been raised. The long-term oncological safety of these applications is not yet clear. On the other hand, the potential role of ctDNA and PRP-derived components in cancer surveillance and personalized oncology treatments is being investigated. Until sufficient long-term evidence is available, it would be appropriate to avoid such bio- logical and cosmetic interventions in patients with a history of cancer or to prefer individualized treatment plans.
Introduction
Letter to the Editor
The purpose of this letter is to highlight the potential clinical implications and importance of circulating tumor cells and DNA in oncology patients undergoing PRP (Platelet-Rich Plasma). The presence of circulating tumor DNA (ctDNA) and tumor cells can be a marker of disease progression and minimal residual disease in solid tumors, similar to hematological malignancies [1].
In recent years, the use of PRP and exosome-based therapies in cosmetic and regenerative medicine has increased. While these products are derived from patients’ own blood and subjected to centrifugation and purification, the theoretical risk of contamination with tumor-derived material from existing or past malignancies remains [2]. Some studies have shown that these biologics may not have adverse effects in the short term; however, the long-term oncological safety of such treat- ments remains uncertain and requires further evaluation [3].
Additionally, many researchers are considering the potential role of circulating tumor DNA and PRP-derived components in cancer treatment monitoring and per- sonalized oncology therapy [4]. However, until sufficient long-term evidence is available, it would be prudent to avoid such biologic/cosmetic interventions or plan individualized treatment for patients with a history of cancer.
