RESUMEN
Objective To study the curative effect of breast-conserving therapy in patients with breast cancer.Methods 100 cases with breast cancer were divided into breast-conserving therapy 50 cases and radical therapy 50 Cases.The primary manner was wide excision of tumor and dissection of axillary lymph node.Adjuvant radiotherapy,chemotherapy and incretion treatment were given postoperatively.Results In 100 cases of breast cancer,the surviral of 83 cases(83.0%),17 patients(17.0%)died,30 cases(30.0%)of metastasis,local recurrence in 13 cases (13.0%);ER,PR-positive are 62 cases(62.0%),both wholly negative in 18 cases(18.0%),ER-positive only 12cases(12.0%),only 8 cases(8.0%)of PR positive;comparing two groups,survival and recurrent rate had no significant difference(X2=3.503,X2=4.284,P＞0.05),metastasis rate was significant different(X2=6.789,P＜0.05);satisfaction degree was 99.0% more than 12 months,and got ideal appearance was over 90%.Conclusion Breastconserving therapy can get long-term effect like Auchineol's.Breast-conserving therapy can gain good cosmetic resuits.
RESUMEN
Objective To evaluate the clinical application of high-frequency ultrasound-guided Mammotome Breast Biopsy System in the biopsy of breast microcalcification.Methods The sterotactic biopsy of microcalcification in breast was performed under the guidance of high-frequency ultrasonography in 24 patients.Results The location of the lesion was accurately determined in all the 24 patients.Pathological findings showed malignant breast tumors in 3 patients(12.5%) and benign breast diseases in 21 patients(87.5%).The malignant tumors included ductal carcinoma in situ in 2 patients and invasive ductal carcinoma in 1 patient.The benign diseases included cystic lobular hyperplasia in 9 patients,ductal hyperplasia and dilation in 6 patients,galactophore cirrhosis in 5 patients,and intraductal papilloma in 1 patient. Conclusions Use of the Mammotome Breast Biopsy System under the guidance of high-frequency ultrasonography is a safe and effective option for the diagnosis of impalpable breast lesions.
RESUMEN
Objective To study the value of BCSG1 on evaluating the curative effect of neoadjuvant chemotherapy(NC) for breast cancer.Methods The expression of BCSG1 in cancer tissue was assayed by immunohistochemistry and RT-PCR in 36 cases of breast cancer patients before and after receiving NC of CEF(cyclophosphamide,epirubicin and fluorouracil) regimen.The therapeutic response of NC was evaluated by morphological and pathological observation.The relationship between expression of BCSG1 and morphological response to NC was analyzed.Results Among the studied cases,the diameter of tumor significantly decreased(P
RESUMEN
Objective To investigate the value of detection of telomerase activity by fine needle aspiration biopsy (FNAB) of thyroid mass in the preoperative diagnosis of thyroid cancer. Methods Comparation of the results of detection of telomerase activity and biopsy of the of samples of thyroid masses aspirated by fine needle guided by B-us were performed .The results were compared to the postoperative pathological results. Results Of the 32 cases of thyroid carcinomas, the correct diagnostic rate of FNAB was 43.8%, while the positive rate of telomerase activity was 75.0%, the difference between the two examinations was significant ( P
