Key inclusion criteria

1. Adult patients with extranodal NK/T-cell lymphoma (ENKL).
2. Patients who underwent treatment with autologous or allogeneic hematopoietic stem cell transplantation.

Study design:
A comprehensive literature search will be conducted in PubMed and Embase according to the search strategy described below (see the "Other" section). No restrictions will be applied with respect to language, country of origin, publication date, study design (prospective or retrospective), single-center or multicenter setting, or registry-based studies. Eligible studies must include at least five patients with ENKL. If a study includes patients with other diseases, only data specific to ENKL patients will be extracted and analyzed.

Key exclusion criteria

1.Duplicate publications
2.Conference proceedings

Data sources and search strategy

Using the search strategy described below, a systematic review (SR) will be conducted in PubMed and Embase on January 11, 2026.

PubMed:
( "Lymphoma, Extranodal NK-T-Cell"[Mesh] OR "NK/T-cell lymphoma"[tiab] OR "NK T cell lymphoma"[tiab] OR "natural killer/T-cell lymphoma"[tiab] OR "natural killer cell lymphoma"[tiab] OR "nasal NK/T-cell lymphoma"[tiab] OR "ENKTL"[tiab] OR "ENKL"[tiab])
AND
( "Hematopoietic Stem Cell Transplantation"[Mesh] OR "hematopoietic cell transplantation"[tiab] OR "stem cell transplant*"[tiab] OR "HSCT"[tiab] OR "bone marrow transplant*"[tiab] OR "peripheral blood stem cell transplant*"[tiab] )

Embase:
( TI,AB("NK/T-cell lymphoma") OR TI,AB("NK T cell lymphoma") OR TI,AB("natural killer/T-cell lymphoma") OR TI,AB("natural killer cell lymphoma") OR TI,AB("nasal NK/T-cell lymphoma") OR TI,AB(ENKL) OR TI,AB(ENKTL))
AND
( TI,AB("hematopoietic stem cell transplantation") OR TI,AB("hematopoietic cell transplantation") OR TI,AB("stem cell transplantation") OR TI,AB("stem cell transplant*") OR TI,AB(HSCT) OR TI,AB("bone marrow transplantation") OR TI,AB("peripheral blood stem cell transplantation"))

Study selection and statistical analysis

Two investigators will independently screen studies according to predefined eligibility criteria. Disagreements will be resolved by discussion or consultation with a third investigator. Study quality will be assessed using the modified Newcastle-Ottawa Scale for single-arm studies.

For the meta-analysis (MA), raw proportions will be pooled using a random-effects model in studies with comparable designs and outcomes. Analyses will be performed using EZR (Saitama Medical Center, Jichi Medical University, Japan). Heterogeneity will be assessed using the I2 statistic, with I2 >30 percent indicating moderate and >60 percent high heterogeneity.
