International prognostic index for lymphomas includes the following prognostic factors, except -: (A) Stage of disease, (B) Number of extralymphatic sites involved, (C) LDH, (D) Hemoglobin and albumin
Answer is D. The prognosis of patients with NHL is best assigned using the International Prognostic Index (IPI) .
This is a powerful predictor of outcome in all subtypes of NHL.
Patients are assigned on IPI score based on the presence or absence of five adverse prognostic factors:-


Age > 60 years
Elevated serum LDH
Performance status 2 (ECOG) or ≤ 70 ( Karnofsky)
> 1 site of extranodal (extra lymphatic ) involvement
Ann Arbor Stage III or IV
