The PreQ-20 Trial


The PreQ-20 Trial is a prospective cohort study to assess the safety, quality of life and cosmetic sequelae of PBR in women with breast cancer and high risk. The study’s main objective is to assess the safety of PBR in terms of postsurgical complications and the feasibility of reconstruction (loss of implants). The secondary objectives are to evaluate oncologic safety (local relapses, residual glandular tissue) and to identify factors related to quality of life and cosmetic sequelae. The evaluation of residual tissue will be conducted by MRI 12 to 18 months after the surgery, and the quality-of-life assessment will be performed using the Breast-Q questionnaire. An initial patient evaluation will be conducted 12–18 months after the surgery, and a second evaluation will be performed at 5 years. The estimated sample size is 81 patients.

The PreQ-20 study will analyze the impact of PBR on 3 separate measures: safety, quality of life and cosmetic sequelae. Unlike other studies that analyzed these three measures jointly for women with breast cancer and high risk, this study will individualize the results for these 2 patient groups. This differentiation is necessary from the methodological point of view, given that the 2 patient groups have separate clinical and emotional implications. The
assessment of these groups will focus on the following aspects: postoperative complications, local relapses, evaluation of residual glandular tissue and incidence rate of primary tumors in the same, the cosmetic sequelae and the satisfaction and the quality-of-life assessment by the patients.
