Brief Summary
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.

Outcome Measures
Primary Outcomes (2)
Overall Survival
Overall survival is defined as the time from the date of initial diagnosis to death from any cause. Participants who are alive will be censored at the date on which their survival status was last confirmed.
From initial diagnosis to death or last confirmed follow-up, assessed for up to 10 years.
Progression-Free Survival
Progression-free survival is defined as the time from the date of initial diagnosis to the first documented disease progression, disease relapse, or death from any cause, whichever occurs first. Participants without an event will be censored at the date of the last assessment confirming absence of progression.
From initial diagnosis to progression, relapse, death, or last disease assessment, assessed for up to 10 years.
Secondary Outcomes (4)
Objective Response Rate
From initiation of first-line treatment through the first-line end-of-treatment assessment, assessed for up to 24 months.
Complete Response Rate
From initiation of first-line treatment through the first-line end-of-treatment assessment, assessed for up to 24 months.
Grade 3 or Higher Adverse Events
During each treatment line, from treatment initiation through treatment completion, assessed for up to 24 months per treatment line.
Treatment-Related Mortality
From initiation of first anticancer treatment to 30 days after the last administered treatment, assessed for up to 10 years across treatment lines.
Other Outcomes (4)
Plasma Epstein-Barr Virus (EBV) DNA Level
Baseline, after 2 treatment cycles, at end of treatment, and at relapse or refractory disease confirmation; assessed for up to 10 years.
Circulating Tumor DNA Mutation Detection Status
Baseline, after 2 treatment cycles, at end of treatment, and at relapse or refractory disease confirmation; assessed for up to 10 years.
Peripheral Blood Immune Cell Subset Frequencies
Baseline, after 2 treatment cycles, at end of treatment, and at relapse or refractory disease confirmation; assessed for up to 10 years.

Study Arms (2)
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.
Eligibility Criteria
Adults aged 18 years or older with a newly diagnosed Epstein-Barr virus-positive T/NK-cell lymphoproliferative disease meeting World Health Organization diagnostic criteria. The retrospective cohort includes consecutive hospitalized patients with extranodal NK/T-cell lymphoma diagnosed from 2017 through 2025. The prospective cohort includes consecutive newly diagnosed patients with extranodal NK/T-cell lymphoma or one of the prespecified rare Epstein-Barr virus-positive T/NK-cell disease entities from 2026 through 2030.
You may qualify if:
- Age 18 years or older.
- Newly diagnosed Epstein-Barr virus-positive T/NK-cell lymphoproliferative disease meeting World Health Organization diagnostic criteria.
- For the retrospective cohort: diagnosis of extranodal NK/T-cell lymphoma between January 1, 2017 and December 31, 2025 at a participating center.
- For the prospective cohort: diagnosis between June 1, 2026 and December 31, 2030 of one of the following:
- 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.
- Availability of essential diagnostic, staging, and treatment information.
- For the prospective cohort: written informed consent and successful collection of the protocol-required baseline peripheral blood specimen.
You may not qualify if:
- For the retrospective cohort: no usable survival follow-up information, inability to confirm survival status, or inability to calculate the principal survival outcomes.
- For the prospective cohort: unwillingness or inability to participate in protocol-defined longitudinal clinical follow-up.

Biospecimen
Peripheral blood samples are collected prospectively before treatment, after two treatment cycles, at the end of treatment or the first formal end-of-treatment assessment, and at relapse or refractory disease confirmation. Each 10-mL blood sample is processed into plasma and peripheral blood mononuclear cells and stored in two aliquots at participating-center biobanks. Optional tumor tissue specimens, preferentially 10-20 unstained slides and no fewer than 5 slides when available, may also be stored. Specimens will be used only for protocol-specified EBV-DNA, circulating tumor DNA, molecular genetic, immune profiling, cytokine, EBV-infected cell subset, and tumor microenvironment analyses.
