A Study to Establish the Diagnostic Value of the EPISEEK-MPE Liquid Biopsy Assay to Identify Cancer in Pleural Effusion Samples. (EPISEEK-MPE)

5. november 2026 opdateret af: Billie Bixby, University of Arizona

Development of a Molecular Assay to Diagnose Malignant Pleural Effusions

The goal of this study is to evaluate the EPISEEK-MPE laboratory test for diagnosis of malignant (cancerous) pleural effusions verses pleural effusions caused by a non-cancer condition. The study uses excess samples drained from around the lung as part of a patient's regular care. The main questions the study aims to answer are:

  1. Is the EPISEEK-MPE test reliable to detect cancer cells and aid in the diagnosis of malignant pleural effusions?
  2. Do age, race, gender and ethnicity change the reliability of the EPISEEK-MPE test?
  3. Can the results of the EPISEEK-MPE test predict which patients have a better chance of survival than others?

Participants will be asked to donate a small portion of the excess fluid drained from around the lung for research. Participants will also give permission to collect data from the medical records.

Detaljeret beskrivelse

In clinical practice, it remains a challenge to distinguish between malignant pleural effusion (MPE) and benign pleural effusion (BPE). Because of the limitations of conventional cytology methods, there is an urgent need to develop a more accurate and effective method for the efficient diagnosis of MPE. In collaboration with the University of Arizona, Precision Epigenomics has developed the EPISEEK-MPE test that has the potential to be an effective complimentary tool for cytology in the process of differential diagnosis. The aim of this project is to conduct a multi-site clinical validation study to establish the EPISEEK-MPE test as a new commercial molecular test for the diagnosis of malignant pleural effusions. The study will: 1) Establish the diagnostic value of the EPISEEK_MPE liquid biopsy assay to identify cancer in pleural effusion and 2) Validate the EPISEEK-MPE liquid biopsy assay for cancer detection in pleural effusion. The long-term goal of this project is to bring the field of pathology a new diagnostic tool for the diagnosis of malignant pleural effusions.

Kohorter og interventioner

Gruppe / kohorte
Benign pleural effusions

Patients with pleural effusions due to infection, heart failure, atelectasis, bronchial obstruction, pulmonary embolism, etc. To be included in the benign group, subjects cannot have any cancer-related history within the last 15 years and chest radiograph will be without evidence of lung mass / malignancy.

Indeterminate pleural effusions

Patients with a known cancer diagnosis, but with cytology negative pleural fluid.

Malignant pleural effusions

Patients with known cancer and a cytology positive pleural fluid sample.
