Combination of Serum Measurements of Molecular Biomarkers and Serum Protein Profiling Can be Used to Predict Which Patients Undergoing Prostatic Biopsy Will be Diagnosed With Cancer

March 8, 2024 updated by: Memorial Sloan Kettering Cancer Center

A Study to Assess if a Combination of Serum Measurements of Molecular Biomarkers and Serum Protein Profiling Can be Used to Predict Which Patients Undergoing Prostatic Biopsy Will be Diagnosed With Cancer

This is a prospective, serum proteomics study of men who are to undergo prostate biopsy. The purpose is to determine if proteomic profiles can be used to distinguish between men with prostate cancer on biopsy from men with no cancer on biopsy.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Patients undergoing prostatic biopsy
This study will enroll two groups of 250 patients who are to undergo prostatic biopsy as part of their routine medical care because of suspicion of prostate cancer (elevated PSA between 2 and 10 ng/ml, abnormal rectal examination, or both). The first group will contain 250 patients of African-American descent and the second will contain 250 Caucasian men.
Patients referred for prostate biopsy as part of their routine care are to be recruited. Patients will undergo standard medical evaluation/care by undergoing a prostate biopsy because of an elevated PSA blood test and/or an abnormal digital rectal prostate examination. The protocol involves obtaining the research blood sample at the time of routine pre-biopsy blood draw. As such, an extra five (40 mL) tubes of blood will be drawn. The serum specimens obtained will be utilized for proteomic profiling comprising MALDI-TOF MS, and serum biomarker assays.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
To determine if men with prostate cancer have a different proteomic profile than men without cancer. Cancer-free status will be confirmed by a re-biopsy at 6 months to reduce the biopsy false negative rate to less than 5 %.
Time Frame: conclusion of study
conclusion of study
To determine whether the peptide proteomic profile can improve the predictive ability of known serum biomarkers (PSA (free and total), hK2 and su-PAR) for prostate cancer.
Time Frame: conclusion of the study
conclusion of the study

Secondary Outcome Measures

Outcome Measure
Time Frame
To determine if Caucasian men and men of African-American descent with and without prostate cancer have different proteomic profiles.
Time Frame: conclusion of the study
conclusion of the study
To assess reproducibility of proteomic profiles over different runs, platforms, and sites.
Time Frame: conclusion of the study
conclusion of the study
To procure a DNA repository from these patients undergoing prostate biopsy for future assessment of kallikrein gene expression.
Time Frame: conclusion of the study
conclusion of the study
To establish a bank of DNA, serum, and frozen lymphoblastoid cells from these patients for the purpose of enabling genetic investigations in men with a diagnosis of prostate cancer.
Time Frame: conclusion of the study
