Primary Outcome Measures:
  • Response rate of central nervous system (CNS) metastasis [ Time Frame: 1 year ] [ Designated as safety issue: No ]

    The response criteria for brain parenchymal metastasis is measured according to the volumetric response criteria with modification. CNS lesion(s) which have a ≧ 50% volumetric reduction of in the absence of progressive neurologic signs and symptoms will be considered as responsive.

    The response criteria for leptomeningeal metastasis is defined as disappearance of carcinoma cells of three consecutive cytology examination of cerebrospinal fluid (CSF) after chemotherapy. For patients with both brain and leptomeningeal metastases, both criteria need to be met to be considered as responsive.



Secondary Outcome Measures:
  • Number of participants with adverse events [ Time Frame: Baseline to until one month after last course of chemotherapy protocol treatment ] [ Designated as safety issue: Yes ]
    To observe the toxicity profile of B-EP according to CTCAE 3.0

  • To evaluate the response rate of breast cancer patients with brain parenchymal metastasis after receiving B-EP [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    To use volumetric measurement by subtraction image of CT the tumor before and after contrast enhancement; assessed every 9 weeks until best response measured

  • To evaluate the response rate of breast cancer patients with leptomeningeal carcinomatosis after receiving B-EP [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    A response is defined as the CSF cytology examination turns from positive to negative. A confirmed response is defined as CSF cytology examination remains negative for two or three consecutive tests

  • To evaluate the response rate of extra-CNS lesions according to RECIST [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    To evaluate the response rate of extra-CNS lesions according to RECIST. Measure every 9 weeks until best response recorded

  • Vascular activity of brain metastatic tumors after bevacizumab treatment [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
    vascular activity detected with dynamic contrast enhanced magnetic resonance imaging (DCE-MRI), measured before treatment, 24 hours after bevacizumab administration and end of 1st cycle of B-EP

  • Biomarkers in CSF and serum in patients with brain and/or leptomeningeal metastasis receiving B-EP [ Time Frame: Before the start of treatment till the end of treatment (after 6 cycles or progression) ] [ Designated as safety issue: No ]
    Prognostic and predictive value of biomarkers in CSF or serum. Serum will be drawn before treatment, end of cycle one and end of 6 cycles of treatment or time of progression

  • Drug concentrations of etoposide and cisplatin [ Time Frame: 12 weeks ] [ Designated as safety issue: No ]
    Drug concentrations of bevacizumab, etoposide in CSF, blood and CSF/blood ratio before and after B-EP treatment in cycle one and cycle two

  • Association between response of CNS metastasis and the history of prior exposure to cisplatin [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    To evaluate the response rate and duration of response of CNS metastasis regarding to prior exposure to cisplatin

  • Proton MR spectroscopy of metastatic brain tumor before and after B-EP treatment [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
    To evaluate the characteristics of 1H-MRS of metastatic brain tumor before and after B-EP treatment
