Quality of life after oncoplastic breast-conserving surgery: a systematic review

Oncoplastic breast-conserving surgery (OBCS) has gained increasing attention as a treatment option for early breast cancer patients, aiming to achieve the best possible breast symmetry with concomitant oncological safety. This paper aims to systematically review the current literature on patient quality of life (QoL) after OBCS compared with QoL after breast-conserving surgery (BCS) alone.

MEDLINE via Ovid, CINAHL via EBSCO and PsycINFO via OvidSP were searched to retrieve all relevant studies. The reference lists of identified eligible studies were manually examined to search for additional eligible studies. The methodological quality of the included studies was assessed using the Critical Appraisal Skills Programme.

A total of six articles met the inclusion criteria. Most of the studies used validated patient-reported outcome measures for assessing QoL with good response rates. However, only one study was of sufficiently good quality to provide good evidence (P < 0.05) in favour of OBCS, while the remainder were of low to moderate quality with differences in outcomes that were not statistically significant.

The review found that the current evidence base is limited and not adequate enough to support or to reject the assumption that OBCS is associated with improved QoL when compared with QoL post-BCS. However, the majority of studies show that OBCS is associated with a trend towards better patient QoL. The impact of OBCS on patient QoL needs to be more adequately investigated. Large prospective cohort studies to assess the impact of OBCS on QoL compared with QoL post-BCS are strongly recommended.
