AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults newly diagnosed with an Epstein-Barr virus-positive T/NK-cell lymphoproliferative disease. No treatment is assigned; the study follows patients and collects blood samples.

Age
18 years or older
Sex
All sexes can join.
Disease stage
Newly diagnosed Epstein-Barr virus-positive T/NK-cell lymphoproliferative disease. Past cohort: extranodal NK/T-cell lymphoma diagnosed between January 1, 2017 and December 31, 2025. New cohort: extranodal NK/T-cell lymphoma, aggressive NK-cell leukemia, systemic chronic active Epstein-Barr virus disease of T/NK-cell type, or Epstein-Barr virus-positive nodal T/NK-cell lymphoma, diagnosed between June 1, 2026 and December 31, 2030.
Biomarker or test result
The disease must be Epstein-Barr virus-positive.

Main reasons for not taking part

  • Past cohort: no usable survival follow-up information
  • Past cohort: survival status cannot be confirmed
  • New cohort: unwilling or unable to take part in the planned follow-up
  • New cohort: no written informed consent or no baseline blood sample

About the trial

What the trial wants to find out

This is a multicenter, non-interventional, ambidirectional cohort study of Epstein-Barr virus-positive T/NK-cell lymphoproliferative diseases. The study consists of a retrospective clinical cohort of 500 consecutively diagnosed patients with extranodal NK/T-cell lymphoma and a prospective clinical-biological cohort of 1,000 newly diagnosed patients with extranodal NK/T-cell lymphoma, aggressive NK-cell leukemia, systemic chronic active Epstein-Barr virus disease of T/NK-cell type, or Epstein-Barr virus-positive nodal T/NK-cell lymphoma.

The study will characterize clinical features, treatment pathways, response, relapse or progression patterns, and long-term survival. The prospective cohort will additionally undergo standardized collection of peripheral blood and optional tumor tissue specimens at predefined clinical time points. Clinical, molecular, viral, and immune biomarkers will be evaluated for their associations with treatment response, treatment failure, disease progression, and survival. No treatment is assigned by the study.

The 2 groups in the trial

  • Retrospective NKTCL Cohort

    Approximately 500 consecutive hospitalized patients with newly diagnosed extranodal NK/T-cell lymphoma diagnosed between January 1, 2017 and December 31, 2025. Clinical, treatment, response, relapse, safety, and survival information is collected from medical records and follow-up records. No biospecimen collection is mandated.

  • Prospective EBV-Positive T/NK Disease Cohort

    Approximately 1,000 consecutive newly diagnosed patients enrolled between June 1, 2026 and December 31, 2030. Eligible diseases include extranodal NK/T-cell lymphoma, aggressive NK-cell leukemia, systemic chronic active Epstein-Barr virus disease of T/NK-cell type, and Epstein-Barr virus-positive nodal T/NK-cell lymphoma. Clinical information, longitudinal outcomes, and protocol-defined biospecimens are collected. Extranodal NK/T-cell lymphoma will represent at least 80% of this cohort.
