Enter the age, gender, stage of disease, albumin level, hemoglobin level, white blood cell count, lymphocyte count, number of extranodal sites, and level of serum LDH into the calculator to determine the Hasenclever Index for Hodgkin’s Lymphoma.

## Hasenclever Index Formula

The following formula is used to calculate the Hasenclever Index for Hodgkin’s Lymphoma.

HI = (0.83 * A) + (0.08 * B) + (0.1 * C) + (0.15 * D) + (0.16 * E) + (0.05 * F) + (0.14 * G) + (0.21 * H) + (0.24 * I)

Variables:

• HI is the Hasenclever Index
• A is the age in years
• B is the gender (1 for male, 0 for female)
• C is the stage of the disease (1 for stage IV, 0 for other stages)
• D is the albumin level (g/dL)
• E is the hemoglobin level (g/dL)
• F is the white blood cell count (x10^9/L)
• G is the lymphocyte count (x10^9/L)
• H is the number of extranodal sites I is the level of serum LDH (U/L)

To calculate the Hasenclever Index, multiply each variable by its corresponding coefficient and sum up the results. The higher the index, the worse the prognosis.

## What is a Hasenclever Index?

The Hasenclever Index, also known as the International Prognostic Index, is a scoring system used to predict the survival rate of patients with advanced Hodgkin’s lymphoma. It takes into account seven factors including age, gender, stage of disease, hemoglobin level, white blood cell count, lymphocyte count, and albumin level. The higher the score, the poorer the prognosis. This index helps doctors to determine the most appropriate treatment plan for the patient.
