Investigating blood biomarkers in anal cancer patients undergoing chemotherapy

Circulating Biomarkers in Patients With Anal Cancer Treated With Induction Chemotherapy

Observational Aarhus University Hospital · NCT05233540

This study is testing if certain blood markers can help predict how well anal cancer patients respond to chemotherapy and their chances of survival.

What this trial studies

This study aims to evaluate the prognostic and predictive value of plasma HPV levels in patients with locally advanced squamous cell carcinoma of the anus who are receiving induction chemotherapy before definitive treatment. It will analyze changes in circulating tumor DNA and other relevant markers during and after treatment to predict patient response and survival outcomes. The research is conducted at three major oncology departments in Denmark, focusing on a rare cancer type that is often linked to HPV. By understanding these biomarkers, the study seeks to improve treatment strategies for anal cancer patients.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with histologically confirmed squamous cell carcinoma of the anus who are receiving induction chemotherapy.

Not a fit: Patients with contraindications for blood sampling or other malignancies within the past five years may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more personalized treatment approaches for anal cancer, improving patient outcomes.

How similar studies have performed: While the specific approach of this study is novel, previous research has shown promise in using circulating biomarkers for cancer prognosis and treatment response.
