Description

Benner et al reported prognostic factors for a patient with mycosis fungoides following large cell transformation (LCT). These can help to identify a patient who may or may not require more aggressive management. The authors are from Leiden University Medical Center in the Netherlands.


 

Patient selection: large cell transformation of mycosis fungoides

 

Prognostic factors:

(1) CD30 positivity on immunostaining

(2) extent of skin lesions

(3) extracutaneous lesions

(4) follicultrophic mycosis fungoides

where:

• Generalized = multiple skin lesions in more than 1 skin location.

• Age >= 60 years was a poor prognostic feature for a patient with skin lesions only.

 

total score =

= SUM(points for all 4 parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 4

• The higher the score the worse the prognosis for the patient.
