ObjectiveTo evaluate the effect of the film positioning method in the neoadjuvant treatment of breast cancer before surgery. MethodsA total of 50 newly diagnosed patients preparing for the neoadjuvant treatment of breast cancer underwent film positioning, and then ultrasonic orientation 1 day after film positioning. The differential between the two positioning methods was observed and measured. All patients received surgery for treatment, preoperative film positioning was conducted on 30 patients, whom were evaluated as stable disease or partial remission, and as lesions larger than 1 cm before surgery, to compare the accuracy degree with postoperative pathological report. ResultsAll of 50 patients were able to receive the film positioning method, which conformed to the range of marked lesions and was easy to use as compared with ultrasonic positioning and pathological lesions. ConclusionThe film positioning method can accurately, non-invasively, and effectively localize the lesions for patients undergoing the neoadjuvant treatment, which can avoid invasive positioning on patients.
