Different Molecular Subtypes of Peripheral T-cell Lymphoma, a Real-world Registry Study. (EXCELLENT Study)

A multi-center, prospective, registry study to analyze the clinical characteristics and prognosis of different molecular subtypes of peripheral T-cell lymphoma.

Detailed Description

Peripheral T-cell lymphoma (PTCL）is a distinct and heterogeneous histopathologic subtype of non-Hodgkin lymphoma (NHL), accounting for ~10%. Patients with PTCL still have poor treatment response and prognosis under conventional CHOP regimen. This multi-center, prospective, registry study is designed to analyze the clinical characteristics and prognosis of different molecular subtypes of PTCL. The results can guide future precision therapy for PTCL.

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

No

Sampling Method

Non-Probability Sample

Study Population

The investigators reviewed previous PTCL genomics and PTCL registry studies worldwide. And the number of PTCL patients admitted to each center per year was investigated. Sample of 1000 PTCL patients was suitable and able to obtain a statistical significant result.

Description

Inclusion Criteria:

  • Patients diagnosed with peripheral T-cell lymphoma (PTCL) by histopathology from June 2026 to December 2029 and detected by gene sequencing (NGS) with different molecular subtypes.
  • Patients diagnosed with PTCL by histopathology from January 2026 to June 2026 and NGS detection can be performed if there is tumor tissue.
  • Fully understand the study, voluntarily sign the written informed consent form (ICF), and agree to cooperate with genetic testing, treatment, efficacy assessment and long-term follow-up.
  • Age ≥ 18 years

Exclusion Criteria:

  • Female patients who are pregnant, breastfeeding, or of childbearing potential without effective contraception;
  • Subjects with poorly controlled neurological, psychiatric, mental or cognitive disorders that may impair their understanding and signing of the informed consent form as well as adherence to the study procedures;
  • Any other conditions deemed inappropriate for enrollment by the investigator.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Progression-free survival
Time Frame: Baseline up to data cut-off (up to approximately 4 years)
Progression-free survival Progression-free survival was defined as the time from the date of randomization until the date of the first documented day of disease progression or relapse, using 2014 Lugano criteria, or death from any cause, whichever occurred first.
Baseline up to data cut-off (up to approximately 4 years)

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Overall survival
Time Frame: Baseline up to data cut-off (up to approximately 4 years)
Overall survival was defined as the time from the date of diagnosis to the date of death from any cause. Reported is the percentage of participants with event. of disease progression or relapse, using 2014 Lugano criteria,or death from any cause, whichever occurred first.
Baseline up to data cut-off (up to approximately 4 years)
Number of Participants With Treatment-Related Adverse Events as Assessed by CTCAE
Time Frame: Baseline up to data cut-off (up to approximately 4 years)
An adverse event is any untoward medical occurrence in a participant administered a pharmaceutical product and which does not necessarily have to have a causal relationship with the treatment. An adverse event can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a pharmaceutical product, whether or not considered related to the pharmaceutical product. Preexisting conditions which worsen during a study are also considered as adverse events.
Baseline up to data cut-off (up to approximately 4 years)
Overall response rate
Time Frame: End of treatment visit (usually 6-8 weeks after last dose on Day 1 of Cycle 6 [Cycle length=21 days]
Percentage of participants with overall response was determined on the basis of investigator assessments according to 2014 Lugano criteria
End of treatment visit (usually 6-8 weeks after last dose on Day 1 of Cycle 6 [Cycle length=21 days]
Complete response rate
Time Frame: End of treatment visit (usually 6-8 weeks after last dose on Day 1 of Cycle 6 Cycle length=21 days]
Percentage of participants with complete response was determined on the basis of investigator assessments according to 2014 Lugano criteria.
End of treatment visit (usually 6-8 weeks after last dose on Day 1 of Cycle 6 Cycle length=21 days]
Duration of response
Time Frame: Baseline up to data cut-off (up to approximately 4 years)
ime from first occurrence of documented CR or PR to disease progression/relapse, or death from any cause for participants with a response of CR or PR. Tumor assessments were performed with PET-CT.
Baseline up to data cut-off (up to approximately 4 years)
Time to Response
Time Frame: Baseline up to data cut-off (up to approximately 4 years)
Time to Response (TTR): Defined as the time from subject enrollment to the first achievement of response (CR or PR).
Baseline up to data cut-off (up to approximately 4 years)
Effects of biomarkers such as gene mutations on treatment response and survival outcomes
Time Frame: Baseline up to data cut-off (up to approximately 4 years)
Targeted sequencing was used to detect 84 genes which can classify PTCL patients into different molecular subtypes.
Baseline up to data cut-off (up to approximately 4 years)
