ABSTRACT
Objective To explore the diagnosis and treatment of cancerization relative to breast intraductal papilloma. Methods Clinical and pathological data of 52 patients with cancerous change of intraductal papilloma were studied retrospectively from January 1998 to December 2008. Results 39 of the 52 cases were diagnosed as malignance or suspected malignance by at least one of the preoperative imaging examinations such as ultrasonography, breast mammography or ductography. Cancer cells were found in 13 of the 46 patients who received fine needle aspiration. Frozen section established the malignance in 18 of the 39 cases. In a postoperative pathological report, 32 cases were cancerization of intraductal papilloma (carcinoma in situ) and 16 were cancerous change with microinvasion, only 4 patients with invasive carcinoma. All the patients received surgical management, 26 of the 52 cases were treated with modified radical mastectomy, 8 of them were performed with breast-conserving surgery (segmental resection plus axillary lymph node resection),7 cases underwent total mastectomy and 11 were just conducted with segmental resection. Only one people was found with axillary node metastasis among the 34 patients who received axillary lymph node dissection.Conclusion The correct preoperative diagnosis of the carcinomatous change of breast intraductal papilloma are always difficult and inconclusive, the frozen section may be helpful and the final diagnosis relied on the fully drawing materials of pathology after the operation. Treatment should be varied based on different pathological findings.
ABSTRACT
Objective To evaluate the feasibility of sentinel lymph node biopsy(SLNB)during surgery of breast cancer. MethodsRadioactive colloid and blue dye were injected intradermally around the tumor seperately before the operation and the SLN were detected first by lymph scintigraphy. SLN was detected and located using ?-finder and the blue dye. Axillary lymph node dissection(ALND)was performed routinely after the SLNB. Results Among 116 breast cancer patients,this procedure was successful in 98.3% of cases. The sensitivity, accuracy and false negative rate were 93.6%, 97.4% and 6.4%, respectively. Conclusions SLNB is a simple, safe and reliable technique.Routine ALND could be raplaced by SLNB in breast cancer patients undergoing surgery.
