Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
It is a research study where patients who are receiving standard chemotherapy (docetaxel 100mg/m2 every 3 weeks) and growth factor (pegfilgrastim 6 mg subcutaneous injection 24 hours after chemotherapy) for metastatic breast cancer will be asked to give blood sample (10 ml) daily from Day 4- Day 11 after first dose of chemotherapy. One more blood sample will be collected on D21. There will not be any further assessment or follow-up as part of the trial. The blood sample will be analysed for stem cells and tumor cells and the effect of treatment will be studied. The patients will continue to receive their treatment as part of routine care.
