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.

Summary
Brief summary
Use of chemotherapy and growth factors can affect the number of stem cells and cancer cells in blood circulation. Few studies have also shown that number of cancer cells can be of prognostic significance. There are no studies till date which have looked systematically at the influence of chemotherapy and growth factors on these cells. Hence present study was designed to answer these questions. The results of the study may not directly influence the way we treat the patients today but will definitely help us to understand the complex nature of breast cancer.
