Eligibility
Inclusion criteria
Inclusion criteria: * Stage I-III breast cancer * scheduled for neoadjuvant chemotherapy with 2 or 3-weekly Adriamycin/Cyclofosfamide, followed by Paclitaxel weekly +/- trastuzumab, for early (stage I-III) breast cancer * willing to undergo an additional ultrasound guided biopsy * ECOG-performance score * 2 (able to perform basic activities of daily living such as walking or biking)
Exclusion criteria
Exclusion criteria: * addition of immuno- or targeted therapy at start neoadjuvant chemotherapy * currently participating in structured vigorous aerobic exercise and/or resistance exercise (*2 days per week). * cognitive disorder or severe emotional instability * presence of other disabling co-morbidity that might hamper physical exercise e.g. heart failure (NYHA classes 3 and 4), chronic obstructive pulmonary disease (COPD, gold 3 and 4), orthopaedic conditions and neurological disorders (e.g., hernia, paresis, amputation, active rheumatoid arthritis); * immunosuppressive medication (e.g. corticosteroids (other than used as part of standard chemotherapy premedication protocol), cyclosporine) * immunodeficiency (primary or secondary) * impossibility to perform an ultrasound-guided biopsy of the tumor
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Feasibility is the primary outcome measure of this study: 1) Recruitment What is the proportion of eligible patients who are willing to participate in this study and undergo an additional tumor biopsy? 2) Quality of tumor material What is the percentage of tumor biopsies that can be assessed successfully from all planned measurements both at baseline and after 6 weeks of neo-adjuvant treatment? We conclude that our pilot-study is feasible if: 1. We achieve a recruitmentrate of at least 20%. 2. At least 50% of the total number of biopsies (both T0 and T1) can be examined successfully on infiltration of NK-cells. | — |
Secondary
| Measure | Time frame |
|---|---|
| Preliminary effects on immune function, IL-6 levels before and after an exercise session and physical fitness. Primary end-point for the preliminary effects is the alteration in number of NK-cells per total number of lymphocytes and in NK-phenotype measured from biopsy tissue. In addition, immune function will be measured from blood. | — |
