| E.2.1 | Main objective of the trial | 
| Phase I: To determine the maximum tolerated dose of local 3D conformal radiotherapy (3DCRT) to the metastatic sites for combined modality treatment with systemic paclitaxel weekly chemotherapy (80mg/m2), followed by systemic chemotherapy with paclitaxel weekly until a total of 8 weeks, in patients with oligometastatic breast cancer Phase II: To determine the effect of systemic paclitaxel weekly chemotherapy  - with or without local 3DCRT to metastatic sites - on progression-free survival, as measured by the one-year progression-free survival rate in patients with oligometastatic brast cancer
 |  | 
| E.2.2 | Secondary objectives of the trial | 
| Phase I: To determine:
 - progression-free survival, as measured by the 9-month progression-free survival rate
 To describe:
 - objective tumor response rate (ORR), ccording to RECIST-Criteria
 - time to progression, as measured by the 1-, 2-, and 3-year progression-free-survival rates
 - toxicity
 - overall survival
 
 Phase II:
 To determine:
 - progression-free survival, as measured by the 9-month progression-free survival rate
 To describe
 -time-to-progression, as measured by the 2- and 3-year progression-free-survival rates
 -toxicity
 -overall survival
 of combined systemic paclitaxel weekly chemotherapy, with or without local 3DCRT, followed by systemic paclitaxel weekly chemotherapy, in patients with oligometastatic breast cancer

 - pregnant or lactating women
 - prior radiation to the metastatic sites
 - prior treatment with taxanes
 - known hypersensitivity to taxanes or Cremophor EL
