Advanced stage HL

Prognostic factors: a prognostic score has been devised by the International Prognostic Factors Project1 for patients with advanced HL.

Seven factors were identified:

• Lymphopenia <0.6 x 109/L or <8% of differential.

Patients with no adverse factors had 5 year failure-free progression of 84%. Each additional factor reduces 5 year failure-free progression by ~7% until the group with 4-7 factors have ~40% failure-free progression at 5 years.
