CLL Prognosis

CLL Prognosis: Factors

The American Cancer Society estimated that 10,020 men and women (6,280 men and 3,740 women) would be diagnosed with chronic lymphocytic leukemia in 2006.
The CLL prognosis will depend on:
  • Whether there is a change in the DNA and the type of change, if there is one
  • Whether lymphocytes are spread throughout the bone marrow
  • The stage of CLL (see Stages of CLL)
  • Whether the cancer gets better with CLL treatment or has recurred (come back)
  • Whether the CLL has spread to lymphoma or prolymphocytic leukemia
  • The patient's general health.


CLL Prognosis: What Are Survival Rates?

Survival rates indicate the percentage of people with a certain type and stage of cancer who survive the disease for a specific period of time after their diagnosis. Often, statistics refer to the five-year survival rate. The five-year survival rate refers to the percentage of people who are alive five years after diagnosis, whether they have few or no signs or symptoms of cancer, are free of disease, or are receiving treatment. Survival rates are based on large groups of people, and they cannot be used to predict what will happen to a particular patient. No two patients are exactly alike, and treatment and responses to treatment vary greatly.

CLL Prognosis: Survival Rates

CLL survival rates can be calculated by different methods for different purposes. The CLL survival rates presented here are based on the relative survival rate. The survival rate measures the survival of the CLL patients in comparison to the general population to estimate the effect of cancer. The overall five-year relative CLL survival rate for 1995-2001 was 74.2 percent.
The five-year relative CLL survival rates by race and sex were:
  • 74.3 percent for Caucasian men
  • 77.1 percent for Caucasian women
  • 53.8 percent for African American men
  • 62.2 percent for African American women.
