Summary: | Nowadays, implant-based breast reconstruction is a common technique after mastectomy. The widespread use of implant employment is prompting significant concerns regarding the oncological safety of prostheses and the potential impact of surface texture on the recurrence of local breast cancer. This article examines the oncological outcomes associated with postmastectomy breast reconstructions using micro- and macrotexturized implants, focusing on the incidence and relative risk (RR).
A retrospective cohort study was conducted on patients admitted to Multimedica group (IRCCS, San Giovanni Hospital, Milan) and ICH groups (Humanitas Clinical Institute, Milan) between January 2003 and September 2020. Minimum follow-up considered was of 1 year. Patients submitted to either complete or nipple-spearing mastectomy, who underwent breast reconstruction with macrotexturized or microtexturized prosthesis, were included in group A and B, respectively.
A total of 646 patients met the basic inclusion and exclusion criteria. Group A included 410 (63.5%) patients and group B included 236 (36.5%). Cancer recurrence absolute risk in group A was 5.6 ± 2.2% and in group B was of 2.1 ± 1.8%. RR for breast cancer recurrence in group A compared to group B was of 2.65; confidence interval 95% (1.02; 6.87). Statistical analysis identified a higher local recurrence risk in patients reconstructed with macrotexturized prosthesis (
-value 0.036).
This study detected a higher risk for local breast cancer recurrence associated to macrotexturized breast implants employment. Further investigations are required to verify these outcomes. |
