[Different influence of Her-2 expression on the prognosis in node-positive and node-negative breast cancer].

Objective: To investigate the prognostic significance of Her-2 expression in node-positive and node-negative breast cancer in Chinese women.

Methods: The Her-2 expression in breast cancers from 981 patients was detected by immunohistochemistry with anti-Her-2 (CB11) monoclonal antibody. The survival curves were analyzed by Kaplan-Meier method, and Cox regression model was applied to determine whether this factor is an independent predictor of survival in multivariate analysis.

[Role of ultrasound-guided needle biopsy of ultrasonographic abnormal axillary lymph nodes in patients with breast cancer].

Objective: To evaluate the utility of ultrasound (US)-guided needle biopsy of ultrasonographic abnormal axillary lymph nodes in the patients with breast cancer.

Methods: The pathological results of US-guided needle biopsy and clinical data of 395 primary breast cancer patients with ultrasonographic abnormal axillary nodes, all female, aged 24 - 83, were analyzed retrospectively.

Results: Node metastasis were detected in 277 (70.

[The early results of breast-conserving therapy in ninety-five patients of primary breast cancer].

Objective: To discuss the effects of breast-conserving therapy in Chinese women with early primary breast carcinoma.

Methods: Ninety-five patients with stage I to II primary breast cancer were operated with wide local excision and axillary lymph node dissection. After operation, the radiation therapy was done on the whole breast.
