Trial summary

This study will evaluate a method to detect tumor cells that are circulating in the blood without getting a biopsy. The investigators already know from other studies that cancer tumors shed a small number of cells into the bloodstream every day. These are called circulating tumor cells (CTCs).

About this study

This study will evaluate a method to detect tumor cells that are circulating in the blood without getting a biopsy. The investigators already know from other studies that cancer tumors shed a small number of cells into the bloodstream every day. These are called circulating tumor cells (CTCs). Some early studies indicate the amount and type of CTCs in the blood can help determine the status of the tumor itself and the way it is responding to treatment. In this study, the investigators will compare the number of CTCs in the blood at different time frames before and after surgery to remove the prostate.

Read the detailed description

The investigators will collect a blood sample for the study when the participant has other blood tests drawn for their cancer treatment. The investigators will take one sample to check prostate specific antigen (PSA) levels and another blood sample for CTC analysis. The investigators will be drawing blood at the following time points: Screening; One day after surgery; 7-14 days after surgery; 3-6 months after surgery; at PSA recurrence or at two years.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Relationship between CTC quantity and pathologic stage

    To evaluate the relationship between pre-operative CTC quantity and pathologic stage in men with early stage prostate cancer undergoing prostatectomy. Processing of the pathology specimen will require up to 2 weeks after surgery.

    Measured: Up to 2 weeks after prostatectomy

  2. Persistent CTC and biochemical recurrence

    To examine the relationship between persistent CTCs and biochemical recurrence after radical prostatectomy for localized prostate cancer

    Measured: 2 year

Secondary outcomes (2)
  1. Compare chromosome translocation status

    To compare the chromosome translocation status (TMPRSS2 fusion with ETS-related genes ERG, ETV1, ETV4, or ETV5) in CTCs with the primary tumor, and examine potential correlations between specific chromosomal translocations with biochemical recurrence.

    Measured: 2 years

  2. Explore other uses of CTCs captured

    To explore hypotheses about other uses of the CTCs captured with teh CTC-Chip, or the RNA or protein isolated from the CTCs, from the patients with localized prostate cancer for potential research and clinical applications.

    Measured: 10 years

Questions about this trial

What is this clinical trial studying?

An observational study of Prostate Cancer, run by Massachusetts General Hospital at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 20 Oct 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Richard J Lee, MD, PhD (617-724-4000), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Relationship between CTC quantity and pathologic stage (time frame: Up to 2 weeks after prostatectomy). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Oct 2026.
