Abstract
Background
Breast reconstruction is a standard procedure in postmastectomy plastic surgery. The necessity of routine histological examinations for mastectomy scars during delayed reconstruction remains a topic of debate. We evaluated the need for histological examination of scars during delayed breast reconstruction.
Methods
We conducted a systematic review using PubMed, TDnet, and Cochrane Central in August 2023. Inclusion criteria involved delayed breast reconstruction with histological scar analysis and malignancy reporting. Exclusion criteria encompassed noncancerous breast diseases, prophylactic mastectomies, articles lacking relevant information, case reports, technique descriptions, and reviews. We independently assessed articles. Differences in recurrence rates were determined using a Z-test for proportions. A linear regression model explored the relationship between reconstruction timing and pathological results. The number needed to treat was calculated based on the literature. The Wilcoxon test was used to compare mean reconstruction times and postreconstruction follow-up between groups.
Results
Our analysis covered 11 retrospective observational studies published between 2003 and 2018, including 3754 mastectomy scars. The malignancy recurrence rate was 0.19%, consistent with previous reports, with a number needed to treat of 144.93-188.68 patients. The timing of breast reconstruction postmastectomy averaged 19.9 months, without statistically significant association between reconstruction timing and recurrence rates. Postreconstruction follow-up periods ranged from 60 to 87 months. The postreconstruction adverse outcomes ratio was 2.21%.
Conclusions
Assessing the necessity of histological examination in breast reconstruction is complex. Based on the literature and this study, we do not recommend routine histological examination of mastectomy scars during delayed reconstruction. A selective approach based on risk factors may be beneficial, warranting further research.
