Real-World clinical features and survival outcomes associated with primary gastrointestinal natural killer/T-cell lymphoma from 1999 to 2020.

ABSTRACT:

Background

Primary gastrointestinal natural killer (NK)/T-cell lymphoma (PGINKTL) is a rare T-/NK-cell lymphoma subtype, and the clinical features and survival outcomes remain largely unknown.

Methods

To summarize the clinical features and survival outcomes of PGINKTL, PGINKTL cases diagnosed at our hospital from May 1999 to December 2020 were reviewed; and the clinical data, information on treatment strategies, and survival were collected. Survival analysis was performed using the Kaplan-Meier method and multivariable Cox proportional hazards regression. We constructed a nomogram to visualize the survival prediction of PGINKTL. The discriminative ability and calibration of the nomogram for prediction were tested using the concordance index (C-index) and calibration plots.
