Clinical Validation of the Prognostic Value of the PrTS on Prostate Cancer Patients

February 10, 2022 updated by: Hongqian Guo, The Affiliated Nanjing Drum Tower Hospital of Nanjing University Medical School

A Single-Center, Retrospective, Blinded Validation Study to Investigate the Prognostic Value of the Prostatype Test System (PrTS) in Prostate Cancer Patients in China

Prostate Cancer is the most common type of cancer among men in many countries. However current clinical tools have limited prediction accuracy to choose the optimal treatment for the individual patient, as prostate cancer risk assessment is a critical aspect of treatment decision-making. A substantial proportion of patients are undergoing over-treatment such as radical treatment, which is often associated with negative physical and psychological side effects, dramatically affecting quality of life in a negative way. Moreover, the patients that are under-treated will face higher cancer mortality risks, which brings more concerns for patients and doctors. Prostatype composes a one-step 4-plex quantitative reverse transcription polymerase chain reaction kit, a database based on authenic patients information and a score system (P-score), intended to measure gene expression levels of three biomarkers: IGFBP3, F3 and VGLL3. Genetic values combined with clinical parameters in the CPMA and P-score are aiming to estimate the aggressiveness of prostate tumor for a newly diagnosed prostate cancer patient. This is a single-center, retrospective, blinded validation study aim to investigate the prognostic performance of the Prostatype test system.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

50 years to 100 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Sampling Method

Probability Sample

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
prostate cancer-specific mortality
Time Frame: up to 36 months
To verify that the prediction performance of risk stratification model (P-score) in the Chinese population is superior to that of the current European Society of Urology (EAU) risk stratification standard with regard to prostate cancer-specific mortality
up to 36 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
metastasis-free survival
Time Frame: up to 36 months
To investigate that the prediction performance of risk stratification model (P-score) in the Chinese population is superior to that of the current European Society of Urology (EAU) risk stratification standard with regard to metastasis free survival
up to 36 months
Prognostic value of the three gene-signature in P-score
Time Frame: up to 36 months
To verify the prognostic value of the three gene-signature (IGFBP3, F3 and VGLL3) in Chinese population, explore their association with prostate cancer-specific mortality and metastasis free survival
up to 36 months

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
