Developing a blood test for early cancer detection

PROFOUND Study: Development and Validation of a Multi-cancer Early Detection Model Based on Peripheral Blood Multi-omic Analysis and Machine Learning: a Multicenter, Prospective, Observational, Case-control Study

Observational Shanghai Weihe Medical Laboratory Co., Ltd. · NCT06217900

This study is testing a new blood test to see if it can help find different types of cancer early by looking at blood samples from both cancer patients and healthy people.

What this trial studies

This observational study aims to develop and validate a machine learning-based model for early detection of multiple cancers by collecting blood samples from newly diagnosed cancer patients and healthy individuals. The study will utilize integrative multi-omic analysis to identify cancer-specific circulating signals. Approximately 10,327 cancer patients and 6,339 age and sex-matched controls will be enrolled to enhance the model's sensitivity in distinguishing early-stage cancers. The model will undergo blinded validation to ensure its effectiveness in clinical settings.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals aged 40-74 who have been clinically or pathologically diagnosed with cancer and have not received any prior cancer treatment.

Not a fit: Patients who are pregnant, have multiple malignancies, or have severe infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to a reliable blood test for the early detection of multiple cancers, potentially improving patient outcomes through earlier intervention.

How similar studies have performed: Other studies have shown promise in using machine learning and blood-based biomarkers for cancer detection, suggesting a potential for success in this novel approach.
