BACKGROUND
Breast cancer is one of the health system problems and important diseases that is rising in developing and advanced countries.
OBJECTIVE
This study aimed to determine the difference of Magnetic Resonance Mammography (MRM) findings versus mammography in detecting multifocal, multi-centric and malignant bilateral lesions in patients with known breast cancer in Tehran.
METHODS
This cross-sectional study was conducted in Iran and Tehran among breast cancer patients between January 2015 and February 2016. Patients were included in the study prior to surgery, at the request of a surgeon with the aim of detecting multifocal, multi-centric and bilateral lesions. Demographic information was also collected from patients. The results for quantitative variables were expressed as mean and standard deviations, and for qualitative variables, were expressed as relative and absolute frequency. Chi-square test was used to compare the two methods. SPSS Ver.24 (IBM) software was used to analyze the data.
RESULTS
Thirty-nine patients were enrolled in the study. The mean age of patients in this study was 48.46±6.836. In mammography, 13 (33.3%) had Composition C and 26 (66.7%) had Composition D according to the type of Composition. In total, 25 patients (89.3%) had one lesion and 3 patients (10.7%) had more than two lesions. In MRM, all lesions observed were mass (54 masses). The number of lesions found in MRM was 27 patients with one lesion (58.9%), 6 patients with two lesions (20.5%) and 5 patients with three lesions (20.6%). MRM detected more lesions compared to mammography (p<0.0001). The value of Chi-square test with a degree of freedom and error level of 0.05 was 3.71 and p<0.0001 that showed a significant relationship between the number of MRM findings in comparison with mammography.
CONCLUSION
The results of our study showed that two or more lesions and bilateral lesions in MRM were more than mammography in women with B Breast Composition C, D; the findings showed that MRM has a better ability to detect breast masses, and can affect the patient's surgical procedure.
背景
乳腺癌是发展中国家和发达国家日益突出的卫生系统问题及重要疾病之一。
目的
本研究旨在确定磁共振乳腺造影（MRM）与乳腺X线摄影在检测德黑兰已知乳腺癌患者的多灶性、多中心性和双侧恶性病变方面的差异。
方法
本横断面研究于2015年1月至2016年2月在伊朗德黑兰的乳腺癌患者中进行。应外科医生要求，在手术前将患者纳入研究，目的是检测多灶性、多中心性和双侧病变。还收集了患者的人口统计学信息。定量变量结果以均值和标准差表示，定性变量结果以相对频率和绝对频率表示。采用卡方检验比较两种方法。使用SPSS Ver.24（IBM）软件分析数据。
结果
39名患者纳入研究。本研究中患者的平均年龄为48.46±6.836岁。在乳腺X线摄影中，根据成分类型，13例（33.3%）为C类成分，26例（66.7%）为D类成分。共有25例患者（89.3%）有一个病变，3例患者（10.7%）有两个以上病变。在MRM中，观察到的所有病变均为肿块（54个肿块）。MRM发现的病变数量为：27例患者有一个病变（58.9%），6例患者有两个病变（20.5%），5例患者有三个病变（20.6%）。与乳腺X线摄影相比，MRM检测到的病变更多（p<0.0001）。自由度为1且误差水平为0.05的卡方检验值为3.71，p<0.0001，表明与乳腺X线摄影相比，MRM发现的病变数量之间存在显著关系。
结论
我们的研究结果表明，在乳腺成分C、D类的女性中，MRM检测到的两个或更多病变及双侧病变比乳腺X线摄影更多；研究结果表明，MRM在检测乳腺肿块方面具有更好的能力，并且会影响患者的手术方案。
