Capecitabine is effective and well tolerated in patients with anthracycline- and/or taxane-pre-treated metastatic breast cancer. We compared the efficacy and safety of capecitabine monotherapy between 1st, 2nd, 3rd and ≥4th line settings for advanced and metastatic breast cancer pre-treated with/without anthracycline and taxanes.


Subjects comprised 84 patients with histologically confirmed advanced or metastatic breast cancer and at least one measurable metastatic lesion. We evaluated time to disease progression (TTP), response rate (RR) and clinical benefit rate (CBR) for 1st (n = 17), 2nd (n = 28), 3rd (n = 23) and ≥4th (n = 16) line setting treatments of capecitabine monotherapy.


Median number of cycles of capecitabine monotherapy was 12 cycles in 1st line, 11 cycles in 2nd line, 9 cycles in 3rd line and 11 cycles in ≥4th line. RR and CBR were 23.5% and 58.8% in 1st line, 21.4% and 53.6% in 2nd line, 21.7% and 52.2% in 3rd line, and 18.8% and 50.0% in ≥4th line, respectively. No significant differences in TTP were seen between each line setting (P = 0.843).


Capecitabine monotherapy is effective and well tolerated in all line settings of chemotherapy in patients with metastatic or advanced breast cancer, and is suitable for outpatient therapy.

Breast ultrasonography has gained widespread acceptance as a diagnostic tool for the evaluation of human breast disorders. It is important to evaluate the correlation of ultrasonography findings with the corresponding histopathological features.


We retrospectively reviewed the 154 cases of breast disorders. We evaluated the correlation the ultrasonography findings and carcinoma cells extension with their corresponding histopathological findings. In addition, we also studied the information on estimation of histological types and cancer extension used by the other modalities such as computed tomography and magnetic resonance imaging.


The concordance rate for margins between ultrasonography findings and histopathological features was 91.6% (P < 0.001) and that for boundary zone was 87.0% (P < 0.001). Histopathological correlation of internal and posterior echoes demonstrated that internal low echo masses were composed of fibroblastic cells with marked collagenization in the stroma, or the cases in which carcinoma cells proliferated in a monotonous, solid and/or expanding manners. Attenuation of posterior echo was detected in the cases associated with hyperplasia of collagenized fibroblastic stroma. An increased cellularity in the mass with prominent large tumor nests and little fibrous stroma demonstrated the accentuation or no alterations of the posterior echo. The concordance rate of borders was 84.4% (P < 0.001). The correlation between estimated histological type by ultrasonography diagnosis and actual histological types was 87.0%. An overall detection rate of carcinoma extension by ultrasonography was 86.4%. In addition, an overall detection rate of carcinoma extension by ultrasonography, magnetic resonance imaging and computed tomography was 93.8%.


These results demonstrated correlation between histopathological and ultrasonographic findings of the breast lesions is cardinal for quality control or improving the quality of ultrasonography.
