ABSTRACT
Objective To summarize and explore the clinical value of Mammotome technology in the diagnosis and treatment of breast neoplasms. Methods Nine hundred and eighty-seven breast neoplasms of 710patients were biopsied and excised with the aid of ultrasound-guided Mammotome system. The malignant neoplasms,according to the histological report,were radically removed during the operation without delay. All patients enrolled into the study were followed up closely on the complcations and satisfaction degree. Results All the operations except one were successful and got the sufficient specimen to perform the pathological examination,the biopsy achievement rate was 99. 8% . Both the sensitivity and specificity of the diagnosis were 100% in 16 breast tumors. Complete resection rate was 99%. The incision length was about 3 mm,showing good cosmetic outcome. Complcations were mild,mainly composed of haematoma and ecchymosis. The patients' general satisfactory rate was 93%. Conclusions This technique can help achieve biopsy of breast neplasm and excision of benign lesions at the same time with cosmetic result Further attention should be paid to reduce the lesion residue and hemorrhagic complications.
ABSTRACT
As an emerging tumor therapy, high intensity focused ultrasound (HIFU) therapy has difficulty in controlling its dosage due to the complex human tissues. The dosage is related to the tumor such as its depth, size, characteristics and the tissue performances of its growth site. The existing cases are applied to establishing a repository with the above-mentioned parameters of the tumor analyzed. Then reasoning and self-learning are performed. So, the therapeutic dosage can be provided to the clinician when a new case occurs.
ABSTRACT
Objective This study was to evaluate breast fiberoptic ductoscopy (FDS) in the diagnosis and treatment of abnormal niple discharge(AND). [WT5”HZ]Methods [WT5”BZ] FVS 3500 superfine fiberscopy system was used to treat and diagnose 200 cases with AND. [WT5”HZ]Results [WT5”BZ] 210 orifices of nipple discharge were found in this group. FDS was successfully inserted into 204 orifices(97 0%).Early breast cancer was found in 9 cases(4 5%), papilloma and papillomatosis in 66 cases(33 0%),ductal ectasia and/or chronic inflammation in 96 cases(48 0%); “normal duct” in 29 cases(14 5%). Duct endoscopic biopsy was carried out in 10 cases. Chronic inflammation was cured by perfusion in 25 cases. 67 cases underwent surgery, diagnosis was confirmed by pathology in 95 0% with a positive rate 3 times as high as that of smear cytology.Conclusions FDS enables the evaluation on 4th ductal lumen and detection of early breast cancer. Interventional treatment was successful in some intraductal papilloma and chronic inflammatory disease.
