RESUMEN
BACKGROUND: Variability in breast reconstruction methods provides an opportunity to investigate whether a method is superior to another with regard to cost, quality, or both. We performed a cost-effectiveness analysis (CEA) study based on tertiary endpoint data from a randomized clinical trial to compare the cost-effectiveness of delayed breast reconstruction by either a latissimus dorsi flap (LD) or a thoracodorsal artery perforator flap (TAP). MATERIAL & METHODS: A total of 50 women were included for unilateral delayed breast reconstruction and were randomized to reconstruction by either the LD flap (n = 18) or the TAP flap (n = 22). The CEA was based on differences in shoulder function after the reconstruction. Direct and indirect costs relating to the two procedures were assessed by the Danish Diagnosis-Related Groups tariffs. RESULTS: Our analysis showed a significant positive effect of introducing the TAP flap on the total shoulder score with an additional cost of $2779. The incremental cost-effectiveness ratio was $4481 and based on a willingness to pay (WTP) $500, we found an estimated net benefit of $519, which was statistically significant (p = 0.0375). The cost-effectiveness acceptability curve indicated that there is a 96.3% probability for the TAP flap being cost-effective to the LD flap at a WTP threshold of $500. CONCLUSION: From a societal perspective, our cost-effective analysis demonstrated that the TAP flap is the more cost-effective method of breast reconstruction compared to the LD flap with respect to patient-reported shoulder-related disability.

BACKGROUND: This paper presents the results of a randomized controlled trial (RCT) that focus on health-related quality-of-life (QoL) and patient-reported satisfaction following breast reconstruction with pedicled flaps from the back. MATERIALS & METHODS: We included women for unilateral delayed breast reconstruction. Patients were randomized to reconstruction by either a latissimus dorsi (LD) flap or a thoracodorsal artery perforator (TAP) flap. Assessment of QoL and patient satisfaction was made using two different patient-reported outcome measures (PROMs): The EORTC QLQ-30 and the Breast-Q questionnaire for post-mastectomy breast reconstruction. RESULTS: A total of 50 women were enrolled over a two-year period and allocated to reconstruction. Forty patients completed both surgery and follow-up and were included in the analysis - 18 in the LD group and 22 in the TAP group. The EORTC QLQ-30 was administered at the baseline and at one-year follow-up. There was no significant effect of introducing the TAP flap on either the summary score, the global QoL-score or the financial impact-score when compared to the LD flap. The Breast-Q questionnaire was administered only at one-year follow-up. There was no significant difference between the two groups for the scores for satisfaction with the reconstructed breast, the overall outcome and QoL related to psycho-social, sexual and physical well-being. CONCLUSION: Women from both groups report high satisfaction and QoL following the reconstruction. The quality of the dataset and the study design are, however, insufficient to rule out any existing difference. A larger cohort, longer follow-up and different design are warranted to assess the true clinical significance these reconstructions might have on satisfaction and QoL.
