Incidence & Mortality
SEER Incidence
From 2001-2005, the median age at diagnosis for lymphoma was 64 years of age3X Close
Table I-11 (http://seer.cancer.gov/csr/ 1975_2005/results_single/ sect_01_table.11_2pgs.pdf). Approximately 3.1% were diagnosed under age 20; 7.7% between 20 and 34; 8.8% between 35 and 44; 13.8% between 45 and 54; 17.3% between 55 and 64; 20.5% between 65 and 74; 21.3% between 75 and 84; and 7.6% 85+ years of age.
The age-adjusted incidence rate was 22.2 per 100,000 men and women per year. These rates are based on cases diagnosed in 2001-2005 from 17 SEER geographic areas.

US Mortality
From 2001-2005, the median age at death for lymphoma was 74 years of age4X Close
Table I-13 (http://seer.cancer.gov/csr/ 1975_2005/results_single/ sect_01_table.13_2pgs.pdf). Approximately 0.6% died under age 20; 2.4% between 20 and 34; 3.4% between 35 and 44; 7.6% between 45 and 54; 13.9% between 55 and 64; 22.9% between 65 and 74; 32.8% between 75 and 84; and 16.5% 85+ years of age.
The age-adjusted death rate was 7.8 per 100,000 men and women per year. These rates are based on patients who died in 2001-2005 in the US.

Trends in Rates
Trends in rates can be described in many ways. Information for trends over a fixed period of time, for example 1995-2005, can be evaluated by the annual percentage change (APC)X Close
The average annual percent change over several years. The APC is used to measure trends or the change in rates over time. For information on how this is calculated, go to Trend Algortihms in the SEER*Stat Help system. The calculation involves fitting a straight line to the natural logarithm of the data when it is displayed by calendar year. . If there is a negative sign before the number, the trend is a decrease; otherwise it is an increase. If there is an asterisk after the APC then the trend was significant, that is, one believes that it is beyond chance, i.e. 95% sure, that the increase or decrease is real over the period 1995-2005. If the trend is not significant, the trend is usually reported as stable or level. Joinpoint analysesX Close
A statistical model for characterizing cancer trends which uses statistical criteria to determine how many times and when the trends in incidence or mortality rates have changed. The results of joinpoint are given as calendar year ranges, and the annual percent change (APC) in the rates over each period can be used over a long period of time to evaluate when changes in the trend have occurred along with the APC which shows how much the trend has changed between each of the joinpoints.

Survival
Survival ratesX Close
Survival examines how long after diagnosis people live. Cancer survival is measured in a number of different ways depending on the intended purpose. Several examples of survival statistics are listed below. can be calculated by different methods for different purposes. The survival rates presented here are based on the relative survival rateX Close
A measure of net survival that is calculated by comparing observed (overall) survival with expected survival from a comparable set of people that do not have cancer to measure the excess mortality that is associated with a cancer diagnosis., which measures the survival of the cancer patients in comparison to the general population to estimate the effect of cancer. The overall 5-year relative survival rate for 1996-2004 from 17 SEER geographic areas was 67.7%. Five-year relative survival rates by race and sex were: 66.2% for white men; 71.0% for white women; 57.0% for black men; 66.1% for black women.
