To systematically clarify the clinicopathological features and outcomes of autologous and allogeneic hematopoietic stem cell transplantation in monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL)/type II enteropathy-associated T-cell lymphoma, with particular attention to reassessing published cases and studies for compatibility with contemporary diagnostic criteria for MEITL.
Safety,Efficacy
Descriptive synthesis of post-transplant outcomes, including overall survival, relapse, and non-relapse mortality
1. Clinicopathological characteristics at diagnosis and at transplantation
2. Disease status before transplantation (CR/PR/SD/PD or non-CR)
3. Clinical context, indications, and treatment course of autologous and allogeneic transplantation
4. Incidence of acute and chronic graft-versus-host disease
5. Pathology-informed reassessment according to contemporary MEITL diagnostic criteria (definite / probable / atypical / uncertain)
Others,meta-analysis etc
| 16 | years-old | <= |
| Not applicable |
Male and Female
1. Studies or case reports involving MEITL, type II enteropathy-associated T-cell lymphoma (type II EATL), or intestinal T-cell lymphomas considered compatible with these entities.
2. Reports describing autologous or allogeneic hematopoietic stem cell transplantation.
3. Case reports, case series, retrospective studies, and prospective studies will be eligible.
4. If a study includes other diseases, only reports in which data specific to MEITL/type II EATL can be extracted will be included.
5. No restrictions will be applied with respect to race, country of origin, publication date, or language.
1. Duplicate publications
2. Conference abstracts only
3. Reports exclusively involving classical EATL/type I EATL
4. Reports with insufficient pathological or clinical information to support compatibility with contemporary MEITL

A systematic search will be conducted using PubMed and Embase. Search terms will include "monomorphic epitheliotropic intestinal T-cell lymphoma," "MEITL," "type II enteropathy-associated T-cell lymphoma," "type II EATL," and "enteropathy-associated T-cell lymphoma type II," as well as related terms such as "intestinal T-cell lymphoma" to avoid omissions due to historical classifications or ambiguous descriptions.
Two investigators will independently screen studies according to the predefined selection criteria to determine eligibility. Discrepancies in screening decisions will be resolved through discussion between the two investigators; if consensus cannot be reached, a third investigator will adjudicate.
At the case or study level, extract data on age, sex, race/ethnicity, diagnostic label, year of diagnosis, stage at diagnosis, primary site, pre-transplant treatment, disease status at transplant, transplant type (autologous/allogeneic), donor, conditioning regimen, GVHD, recurrence, non-recurrence-related death, and survival outcomes.
Furthermore, we will extract pathological features such as morphology (monomorphic, epitheliotropism), immunophenotype (CD3, CD4, CD8, CD56, CD30, EBER, TIA-1, granzyme B, etc.), and celiac disease-related findings, and classify their consistency with the current MEITL into definite, probable, atypical, or uncertain.
Because of substantial heterogeneity in diagnostic criteria, transplant indications, outcome definitions, and time-zero definitions (diagnosis vs transplantation), a quantitative meta-analysis will not be performed in principle. Instead, findings will be synthesized, separately summarizing the background, pathology-informed diagnostic compatibility, transplant context, and outcomes of autologous and allogeneic transplantation.
