An observational study in Breast Cancer Female, sponsored by Vincent Vinh-Hung. Status unknown at 1 site in Switzerland. Open to female participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2022-12-21.
Sponsored by Vincent Vinh-Hung · Observational
The study purpose is to evaluate whether or not clinical characteristics of women with breast cancer can predict which position for radiation treatment, prone or supine, will be associated with a dosimetry gain. Dosimetry gain in this study means the lowest radiation dose to non-target organs (heart, lungs, contralateral breast), while giving the prescribed dose to tumor bed and ipsilateral breast.
Retrospectively identify women who received curative radiation treatment after breast conserving cancer surgery, in whom simulation in prone and in supine position was performed. Compare the treatment plans for doses to targets and to non-target organs, according to clinical parameters of body mass index, size of breast, location of tumor and side. Furthermore, evaluate whether a single CT slide is enough or not to predict a dosimetry advantage.
12,544 studies on the registry are indexed under Breast Neoplasms; 2,892 are open to participants now.
This study's planned enrollment of 280 is above the median of 184 across 2,642 observational studies indexed under Breast Neoplasms.
