To assess the value of X-ray mammography and cytopathology test for breast cancer diagnosis of early stage Tis and T1

ABSTRACT

Background: Breast cancer is not only the most popular in women but is also one of the main causes of death among them in many countries. In Hanoi 1999, the prevalence of breast cancer was 21.8 per 100,000 of the population and was the main cause of death in women. In Ho Chi Minh city that prevalence was 17.1 per 100,000 of the population and was the second highest cause of death in women. Objectives: To assess the value of X-ray mammography and cytopathology test for breast cancer diagnosis of early stage Tis and T1. Subjects and method: A retrospective study was conducted among 103 breast cancer patients with malignant tumor size \uf0a32cm, who were admitted to K Hospital and Thanh Nhan Hospital from 01/2003 to 02/2008. Results:Breast malignant tumor was usually found most frequently at the upper outer quadrant. Around 86.4% of patients who were suspected with malignant lesion by X-ray mammography. Using biopsy test for breast cancer diagnosis, the results shows that 78.6% of patients were positive, 15.6% of cases were suspected and 5.8% had wrong diagnosis. Pathologic classifications were as followed: invasive lobular carcinoma: 78.6%, intraductal carcinoma in situ (Tis): 4.9%. Conclusion: X-ray mammography and cytopathology test are useful tools for the diagnosis of breast cancer.
