| Scientific title | Standardisation of breast radiotherapy (START) trial |
| Study acronym | START |
| Study objectives | To test the effects of radiotherapy schedules using fraction sizes larger than 2.0 Gy in terms of normal tissue responses, loco-regional tumour control, quality of life and economic consequences in women prescribed postoperative radiotherapy for early breast cancer. |
| Ethics approval(s) | Added 30 July 2008: South East London (MREC 98/96) - approved 30/09/1998 |
| Health condition(s) or problem(s) studied | Breast cancer |
| Intervention | Radiotherapy schedules using fraction sizes larger than 2.0 Gy |
| Intervention type | Other |
| Primary outcome measure(s) |
In this study several endpoints are being investigated (tumour recurrence, normal tissue effect, quality of life). It is intended that each will be analysed separately. If there is discordance between the endpoints in terms of treatment outcome this will allow discussion of clinical trade-offs. In a subset of patients there will be a detailed assessment of quality of life. Health economic consequences will also be determined. |
