Survival up for those diagnosed in 2009 versus 2000, 1990, 1983; no change for stage IV tumors
THURSDAY, Nov. 19, 2015 (HealthDay News) — For women with stage I to III cervical cancer, relative survival has improved over time, although no significant improvements have been seen for women with stage IV tumors, according to a study published in the November issue of the American Journal of Obstetrics & Gynecology.
Jason D. Wright, M.D., from Columbia University in New York City, and colleagues examined relative survival in 46,932 cervical cancer patients diagnosed from 1983 through 2009 and recorded in the Surveillance, Epidemiology, and End Results database. Changes in stage-specific relative survival were compared with the general population matched by age, race, and calendar year.
The researchers found that for women with stage I tumors, the excess hazard ratios were 0.91, 0.81, and 0.75 for women diagnosed in 2009 versus 2000, 1990, and 1983, respectively. For patients with stage III tumors, the excess hazard ratios were 0.83, 0.68, and 0.59 for women diagnosed in 2009 relative to those diagnosed in 2000, 1990, and 1983, respectively. Women with stage II tumors had similar trends in improved survival. For women with stage IV tumors there was no statistically significant improvement in relative survival over time.
“Relative survival has improved over time for women with stage I to III cervical cancer, but has changed little for those with metastatic disease,” the authors write.
