Data analysis of mammography in spective for breast cancer in Shanxi cancer hospital / 肿瘤研究与临床

ABSTRACT

Objective To evaluate this disease' s incident trend for Shanxi province through hospital-based statistics. Methods Breast cancer data was obtained from the department of radiology in Shanxi cancer hospital for the period 2005-2007. Results Between 2005 and 2007, the numbers of women who accepted mammography rapidly increased from 533 to 1975. 62 women had been diagnosed as breast cancer in 2005, while this number had reached to 400 in 2007. The proportion of breast malignancies during this three year periods had statistically increased with 11.6 %, 17.8 %, and 20.3 % respectively (P<0.001). The mean age of breast cancer patients was older than benign disease patients (50 vs 42.8, P<0.001). The highest breast cancer age group was those aged 45 to 54 (37.6 %). Left breast cancer was higher than right side (53.4 % vs 46 %). Most histological type was invasive ductal carcinoma (78.95 %). The proportion of invasive lobular carcinoma and duetal carcinoma in situ were 8.7 % and 5.4 % respectively. Conclusion Breast cancer incidence rate has been increased in our city. These results are consistent with previous similar studies. Thus, it is essential to establish population cancer incidence registration and develop clinical data system. This will result in better understanding of cancer incidence trends and benefit in the evaluation of the effective cancer control measures.
