Metabolic and Immunomic Differential Analysis of Primary Central Nervous System Diffuse Large B-Cell Lymphoma

November 15, 2025 updated by: Ting YANG

Differential Analysis of Primary Central Nervous System Diffuse Large B-Cell Lymphoma Based on Metabolomics and Immunomics

This study is a prospective cohort study. The case group will include patients with primary central nervous system lymphoma confirmed by imaging and pathology. The control group will include patients with pathologically confirmed diffuse large B-cell lymphoma who have been excluded from central nervous system involvement, as well as age- and gender-matched healthy volunteers (hematopoietic stem cell donors). Baseline data (as described below) will be collected. Patients with primary CNS lymphoma will undergo follow-up every 3 months, with immediate follow-up if clinical symptoms arise.

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

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Sampling Method

Non-Probability Sample

Study Population

Hematopoietic stem cell donor

Description

Inclusion Criteria:

  1. Aged between 18 and 75 years.
  2. The case group must have a confirmed diagnosis of primary central nervous system lymphoma (PCNSL) and must not have received any antitumor therapy prior to baseline sample collection.
  3. Must sign an informed consent form, agree to participate in this study, and provide samples and clinical information as required.
  4. Case group patients must have complete supporting imaging and pathology data.

Exclusion Criteria:

  1. Presence of other systemic malignancies.
  2. Presence of severe infections or metabolic disorders.
  3. Use of antimetabolites or chemotherapy drugs within one week prior to sample collection.
  4. Pregnant or lactating women.
  5. Concurrent severe internal medical conditions (e.g., end-stage renal disease, heart failure, liver failure).
  6. Patients unable to complete study requirements due to psychiatric disorders or cognitive impairment.

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
Metabolomics
Time Frame: Before the start of the first treatment cycle, at the end of each treatment cycle(each cycle is 28 days)
Detection of metabolites in plasma using liquid chromatography-mass spectrometry (LC-MS) technology
Before the start of the first treatment cycle, at the end of each treatment cycle(each cycle is 28 days)
CYTOF
Time Frame: Before the start of the first treatment cycle, at the end of each treatment cycle(each cycle is 28 days)
Immunophenotyping of PBMCs using flow cytometry mass spectrometry (CYTOF)
Before the start of the first treatment cycle, at the end of each treatment cycle(each cycle is 28 days)

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
OS
Time Frame: From date of randomization until the date of the end of follow-up or date of death from any cause, whichever came first, assessed up to 12months
Overall survival
From date of randomization until the date of the end of follow-up or date of death from any cause, whichever came first, assessed up to 12months
PFS
Time Frame: From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 12months
Progression-free survival
From date of randomization until the date of first documented progression or date of death from any cause, whichever came first, assessed up to 12months

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 1, 2025

Primary Completion (Estimated)

Primary Completion

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.
March 1, 2026

Study Completion (Estimated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
