The study of coordinate orientation and surgery method for the palpation-negative breast cancer

Objective:To study the methods of localization and effects of surgical treatment for palpation-negative breast cancer.Methods:From November 2003 to August 2007,61 patients with neither touchable mass nor mass image in radiography were diagnosed early breast cancer(T1-2N0M0)according to malignant calcification focus shown by radiography with molybdenum tube or rich local blood supply shown by B-type ultrasonic examination in Jiangsu Province Tumor Hospital.Patients with single lesion received breast-conserving surgery,which meaned the cancer lesion was excised precisely with the aid of preoperative localization by FFDM coordinate orientation,and breast reconstruction was accomphished synchronously by wide-based gland tissue flap stageⅠbreast reconstruction.patients with multiple lesion received modified radical mastectomy.Results:In the breast-conserving surgery given to the 50 patients,the accuracy of localization was 100%(50/50);breast single focus were excised completely with margin negative by FFDM and pathological examination;the superior rate of mammaplasty was 86%(43/50) according to JCRT.Complience difference was 1.5cm.Modified radical mastectomy on breast cancer was given to the 11 patients with breast extramammary diffusive calcified focus.The follow-up time was 6 to 58 months in 61 patients(average time was 39 months),1 case distant metastases and no local recurrence was observed.Conclusion:Lesion localization in patients with breast single focus,breast-conserving surgery followed by synchronous wide-based gland-tissue flap stageⅠbreast reconstruction is a new recommendable technique for breast minimally invasive surgery for its simple maneuver,minimal invasion and produces a fairly well-shaped.Such treatment is especially suitable for Chinese female patients with small breast.
