Background: Conventional breast-conserving surgery (C-BCS) has equal oncological outcomes and superior cosmetic and patient-reported outcomes compared to mastectomy with immediate two-stage implant-based breast reconstruction (M-IBR). Oncoplastic breast-conserving surgery (OP-BCS) is increasingly being used, as it often has better cosmetic results and it enables larger tumour resection. However, OP-BCS and M-IBR compared to C-BCS lengthens operative time and might lead to more complications and consequently to additional costs.

Background: The aim was to evaluate the cost-utility of four common surgical treatment pathways for breast cancer: mastectomy, breast-conserving therapy (BCT), implant breast reconstruction (BR) and autologous-BR.

Methods: Patient-level healthcare consumption data and results of a large quality of life (QoL) study from five Dutch hospitals were combined. The cost-effectiveness was assessed in terms of incremental costs and quality adjusted life years (QALYs) over a 10-year follow-up period.

Background: The goal of postmastectomy breast reconstruction (BR) is to improve the quality of life of patients. However, complications following autologous BR (A-BR) and implant-based BR (I-BR) occur frequently and may even lead to BR-failure, which can be a distressing event for both patients and surgeons. The current study, therefore, examines the experiences of both patients and surgeons after a BR-failure.

Background: Differences in quality-of-life outcomes after different surgical breast cancer treatment options, including breast reconstruction, are relevant for counseling individual patients in clinical decision-making, and for (societal) evaluations such as cost-effectiveness analyses. However, current literature shows contradictory results, because of use of different patient-reported outcome measures and study designs with limited patient numbers. The authors set out to improve this evidence using patient-reported outcome measures in a large, cross-sectional study for different surgical breast cancer treatment options.

Background: The EuroQol EQ-5D-5L instrument is the most widely used quality of life (QoL) measure in health economic evaluations. It is unclear whether such a generic instrument is valid enough to estimate the benefits of breast reconstruction (BR), given the specific changes observed in QoL after BR. Hence, we aimed to evaluate the validity of the EQ-5D-5L in patients who had undergone postmastectomy BR.

Background: Scars can cause pain, even without symptoms of underlying nerve damage. A lack of knowledge on intrinsic scar pain hampers effective treatment of these complaints.

Objective: Aggregate current knowledge on the prevalence, etiology, and pathophysiology of intrinsic pain in dermal scars.

Keloid scars may be painful, itch severely and be cosmetically disturbing. The burden of keloid disease, however, has not yet been determined. This study evaluated the association of keloid disease with health-related quality of life (HRQL) and identified indicators of burden using a cross-sectional survey study, with one disease-specific HRQL measure (Skindex-29) and 2 generic HRQL measures (SF-36 and EQ-5D-5L).

Adjuvant chemotherapy is often needed to achieve adequate breast cancer control. The increasing popularity of immediate breast reconstruction (IBR) raises concerns that this procedure may delay the time to adjuvant chemotherapy (TTC), which may negatively impact oncological outcome. The current systematic review aims to investigate this effect.
