abstract
The
incidence and the trend of gynaecological cancers have been suggested to
vary by ethnicity and geographical regions. Whether the incidence and
type of gynaecological cancers in China is different have not been fully
investigated. In this study, we reported the trend of gynaecological
cancers in China. Data on 13,518 women with gynaecological cancers were
collected from the largest obstetrics and gynaecology hospital in China
from 2003 to 2013. Data included age at diagnosis and the annual number
of women with diagnosed endometrial, ovarian, cervical cancer and other
gynaecological cancers. The number of women with diagnosed
gynaecological cancers increased by almost sixfold in 2013 compared to
that in 2003. It was largely due to the increase of women with newly
diagnosed cervical cancer. The percentage of women with endometrial and
ovarian cancer within total gynaecological cancers was decreased, whilst
the percentage of cervical cancer significantly increased between 2003
and 2013. The mean age of women with endometrial or ovarian cancer at
diagnosis was 53 or 48 years, respectively, which was no difference over
11 years. However, the mean age of women with cervical cancer at
diagnosis was significantly delayed from 42 years in 2003 to 46 years
since 2011. This was also confirmed by the age-specific distribution of
gynaecological cancers over 11 years. Our study found that the age onset
of endometrial and ovarian cancer has not changed over 11 years. But
the age onset of cervical cancer is delayed since 2011 in China.
