Improvement in survival of older adults with multiple myeloma: results of an updated period analysis of SEER data

Abstract

Background: Treatment of multiple myeloma has changed significantly over the past several years with clinical trials reporting superior survival results using newer agents. Previous work has shown that the survival rate has improved for younger, but not older, patients with myeloma. Here, we update survival estimates for patients with myeloma in the early 21st century to determine whether continued improvement can be seen on a population level and whether or not it now extends to older patients.

Methods: Using period analysis to examine data from the Surveillance, Epidemiology, and End Results database, we estimate changes in the 5- and 10-year relative survival rates (RSRs) from 1998-2002 to 2003-2007.

Results: The 5- and 10-year RSRs have improved for patients with myeloma overall, from 32.8% and 15% in 1998-2002 to 40.3% and 20.8%, respectively, in 2003-2007. The greatest improvements were observed for patients aged 15-44 years, with 5- and 10-year RSRs reaching >70% and ~50%, respectively, but improvements were also seen for patients aged >70 years.

Conclusion: Overall, survival continues to improve for patients with myeloma, including older patients, suggesting that newer treatment options continue to make a population-wide impact.
