Overview

Tcell lymphoma may be classified according to The 2016 WHO update on mature T- and natural killer (NK) cell neoplasms that is is cearly updating the 2008 WHO (World Health Organization) classification.

OR

[Disease name] may be classified into [large number > 6] subtypes based on [classification method 1], [classification method 2], and [classification method 3]. [Disease name] may be classified into several subtypes based on [classification method 1], [classification method 2], and [classification method 3].

OR

Based on the duration of symptoms, [disease name] may be classified as either acute or chronic.

If the staging system involves specific and characteristic findings and features: According to the [staging system + reference], there are [number] stages of [malignancy name] based on the [finding1], [finding2], and [finding3]. Each stage is assignjsak /number1] and a [letter/number2] that designate the [feature1] and [feature2].
