Phase II Trial of Oxaliplatin in Combination With S-1(SOX) in Patients With Recurrent or Metastatic Breast Cancer (MBC) Previously Treated With or Resistant to an Anthracycline and Taxane


The main purpose of this study is to find out the efficacy and safety profile of TS-1 with
oxaliplatin in previously anthracycline and taxane pretreated patients.


Inclusion Criteria:

the diameter is confirmed to be 10mm in spiral CT or multidetector CT (MD CT), or 20
mm or longer in conventional CT

- No prior treatment with S-1, capecitabine, platinum In metastatic setting

- Must have received an anthracycline and taxane in adj. or metastatic settings
(concurrent, sequential, or combined with other drugs)

- For taxanes (Paclitaxel (P) / Docetaxel (D))

1. Must have progressed while or after receiving P or D (Patients who relapse
within 12 months of completing adjuvant chemotherapy containing an anthracycline
and a taxane, do not require prior chemotherapy for metastatic disease)

2. Only 1 adjuvant regimen permitted (neoadjuvant immediately followed by surgery
and immediately followed by adj. is permitted)

- For anthracyclines

1. Progressed while on anthracycline treatment, with or without initial response or

2. Have received an adequate course of anthracyclines defined as follows:

1. Adj.: Must have received a standard regimen (doxorubicin ≥ 240 mg/m2 or ≥ 360
mg/m2 epirubicin or equivalent)

equivalent)
