Race Gap Seen in Endometrial Cancer
Advanced Endometrial Cancer Survival Rate: Worse for Blacks Than Whites
Sept. 25, 2006 -- Even with similar medical care, advanced endometrial
cancer survival rates are 26% worse for black women than white women.
That news appears in Cancer's November edition.
Data came from four studies of women with advanced endometrial cancer. The
endometrium is the inner lining of the uterus.
G. Larry Maxwell, MD, and colleagues combined the data from all four studies
to check survival rates for 169 black women and 982 white women.
Maxwell works at the Walter Reed Army Medical Center in Washington.
Maxwell's team found that the women in those four studies got comparable,
aggressive medical care for endometrial cancer.
Even so, survival rates were 26% worse for the black women, the study
Reasons for Racial Gap Unknown
Average survival was one year for white women, compared to 10.6 months for
black women. The odds of surviving for two years were 26% for white women and
14% for black women.
The study doesn't pinpoint the reasons for the racial gap.
However, the researchers note that black women were more likely to have
"poorly differentiated tumors." That means those cancer cells may be
"It appears that, once an advanced-stage or recurrent tumor becomes
poorly differentiated, survival worsens irrespective of racial status,"
write Maxwell and colleagues.
Other biological, socioeconomic, or cultural factors may also in be
involved, the researchers note.
