Introduction: Implant-based or expander-supported breast reconstruction is an established surgical method after mastectomies due to cancer or to prophylactic reasons. Patient reported outcome (PRO) and cosmetic outcome after breast reconstruction with a synthetic surgical mesh was investigated in a prospective, single-arm, multi-center study. Material and methods: Primary or secondary implant-based breast reconstruction with support of TiLOOP® Bra was performed in 269 patients during the PRO-BRA study. PRO 12 months after breast reconstruction was evaluated using Breast-Q questionnaire. Cosmetic outcome was evaluated by two independent experts by means of pictures taken preoperatively and at the follow-up visits. Results: Breast-Q and 12 months FU were completed by 210 women. Patients without adverse event had a significantly higher Breast-Q score for "sexual well-being" (p ¼ 0.001); "psychosocial well-being" was negatively influenced by prior therapies (p < 0.01), and older patients had significantly lower scores at 12 months FU compared to pre-OP for "satisfaction with breasts" (p < 0.01) while the opposite was true for younger patients. Unilateral surgery resulted in reduced "satisfaction with breast" at 12 months FU (p < 0.01). Radiotherapy negatively influenced "satisfaction with breast", "sexual well-being" and "physical well-being chest". The cosmetic evaluation showed a significant difference (p < 0.001) in the evaluation by the patients and experts with the patients' assessment being worse compared to experts' assessment.
Conclusion:Our study showed that two years after implant-based breast reconstruction with support of TiLOOP® Bra PRO is influenced by different factors. This information can be used to improve the decision-making process for women who chose implant-based breast reconstruction.
