# Comparison of Set-up Reproducibility Between Prone and Supine Intensity Modulated Radiotherapy (IMRT) for the Adjuvant Treatment of Breast Carcinoma After Lumpectomy

**NCT ID:** [NCT00887692](https://clinicaltrials.gov/study/NCT00887692)

## Key Facts

- **Status:** COMPLETED
- **Phase:** NA
- **Study Type:** INTERVENTIONAL
- **Target Enrollment:** 10
- **Lead Sponsor:** University Hospital, Ghent
- **Conditions:** Breast Carcinoma
- **Start Date:** 2009-07
- **Completion Date:** 2010-10
- **CT.gov Last Update:** 2010-10-19

## Brief Summary

10 patients will be treated alternating daily between prone and supine position for breast radiotherapy to compare set-up accuracy. Prone treatment will be given on the odds days and supine treatment on the even days.

## Eligibility

- **Minimum age:** 18 Years
- **Sex:** FEMALE
- **Healthy Volunteers:** No

```
Inclusion Criteria:

* female patients
* multidisciplinary decision of adjuvant radiotherapy after lumpectomy for breast cancer
* minimum 18 years
* informed consent obtained, signed and dated before specific protocol procedures.

Exclusion Criteria:

* mastectomy
* need for axillary irradiation
* bilateral breast irradiation
* previous irradiation at the same time
* pregnant or breastfeeding
* mental condition rendering the patient unable to understand the nature, scope and possible consequences of the study.
* patient unlikely to comply with the protocol; i.e. uncooperative attitude, inability to return for follow-up visits, and unlikely to complete the study.
```

## Interventions

- **prone and supine position** (BEHAVIORAL) — patients will be treated alternating daily between prone and supine position for breast radiotherapy.

## Primary Outcomes

- **Random set-up error** _(time frame: daily during radiotherapy)_

## Secondary Outcomes

- **Systemic set-up error** _(time frame: daily during radiotherapy)_
- **Respiration-related motion amplitude**
- **time of treatment delivery** _(time frame: daily during radiotherapy)_
- **Dose-volume parameters** _(time frame: of planning)_
