¹By Fisher’s exact test. FDG-PET: Fluorodeoxyglucose positron emission tomography; DLBCL: Diffuse large B-cell lymphoma; FL: Follicular lymphoma; MCL: Mantle cell lymphoma; ETL: Enteropathy associated T-cell lymphoma; ALCL: Anaplastic large cell lymphoma; MLP: Multiple lymphomatous polyposis; PS: Performance status; NS: Not significant.
