Clinical and patient-reported outcomes after oncoplastic versus conventional breast conserving surgery-a longitudinal, multicenter cohort study.

Background: Oncoplastic breast conserving surgery (OP-BCS) is becoming increasingly popular to avoid mastectomy or optimize cosmetic outcomes of breast conserving surgery (BCS). Few studies have compared clinical outcomes and patient-reported outcomes (PROs) of OP-BCS to conventional BCS (C-BCS). This study aims to compare clinical outcomes and short and long-term PROs after OP-BCS and C-BCS in a large prospective breast cancer cohort.

International study to develop a patient-reported outcome measure to evaluate outcomes of gender-affirming care - the GENDER-Q.

Background: To meaningfully understand outcomes of gender-affirming care, patient-reported outcome measures (PROMs) that are grounded in what matters to individuals seeking care are urgently needed. The objective of this study was to develop a comprehensive PROM to assess outcomes of gender-affirming care in clinical practice, research, and quality initiatives (the GENDER-Q).

Methods: Internationally established guidelines for PROM development were used to create a field test version of the GENDER-Q.

The Impact of Scars After DIEP-Flap Breast Reconstruction on Satisfaction and HR-QoL: A Cross-Sectional Study Comparing BREAST-Q Scores.

Background: Although deep inferior epigastric perforator (DIEP) flap breast reconstruction is the most widely used technique for autologous breast reconstruction, this technique leads to large scars in visible areas on breast and abdomen. So far, limited studies have thoroughly addressed the impact of breast and abdominal scars on satisfaction and Health-related Quality of Life (HR-QoL).

Objectives: This research aimed to determine whether women with no/minor scar symptoms after undergoing DIEP-flap breast reconstruction differ in satisfaction and perceived HR-QoL from women with symptomatic scars.

Breast cancer patients' needs and perspectives on a one-on-one peer support program: quantitative and qualitative analyses.

Purpose: Although peer support programs as a health resource have become increasingly popular, only limited studies evaluated the added value of one-on-one peer support for breast cancer patients. This study aims to bridge the knowledge gap by focusing on two related research topics. First, we evaluated emotional well-being and (unmet) needs regarding supportive care.

Efficacy of indocyanine green fluorescence for the identification of non-palpable breast tumours: systematic review.

Background: Accurate tumour localization is crucial for precise surgical targeting and complete tumour removal. Indocyanine green fluorescence, an increasingly used technique in oncological surgery, has shown promise in localizing non-palpable breast tumours. The aim of this systematic review was to describe the efficacy of indocyanine green fluorescence for the identification of non-palpable breast tumours.

Ensuring access to post-cancer breast reconstructions: COVID-19 lessons from the Dutch Breast Implant Registry.

Background: COVID-19 has impacted breast implant surgery for oncological and non-oncological patients worldwide. This population-based study aimed to evaluate the impact of the COVID-19 pandemic on access to reconstructive and cosmetic breast implant surgery in the Netherlands using real-world data to describe trends, and to identify lessons to prevent future capacity problems within (inter)national healthcare.

Methods: This longitudinal study included patients undergoing breast implant surgery from the mandatory nationwide Dutch Breast Implant Registry.

Risk Factors for Unplanned Reoperation during the Expansion Phase in Two-Stage Breast Reconstruction in the Dutch Breast Implant Registry.

Background: The majority of postmastectomy breast reconstructions (PMBRs) are currently performed in two stages using a tissue expander (TE). However, complications during the expansion phase occur regularly, leading to unplanned reoperations and/or reconstruction failure. This study aimed to identify risk factors for unplanned reoperation after TE placement, assessed the time until unplanned and planned reoperation, and investigated indications for unplanned reoperation.

Patients' and Healthcare Professionals' Perspectives on Better Use of Patient-Reported Outcome Measures in Head and Neck Cancer.

Objectives: Patients with head and neck cancer (HNC) are often highly affected by disease and treatment, resulting in impaired physical functioning and quality of life. Therefore, evaluation of patients' psychosocial and functional outcomes can be facilitated by patient-reported outcome measures (PROMs). By providing the patients' own perspectives, PROMs are crucial to improving patient-centered care.

Revision Incidence after Immediate Direct-to-Implant versus Two-Stage Implant-Based Breast Reconstruction Using National Real-World Data.

Background: In immediate implant-based breast reconstruction (IBBR), large variation is observed in current practices between a direct-to-implant and a two-stage approach (insertion of a breast implant after a tissue expander). This population-based study aimed to compare unplanned short- and long-term revision incidence between direct-to-implant and two-stage IBBR in The Netherlands.

Methods: All patients who underwent immediate IBBR following a mastectomy between 2015 and 2019 were selected from the nationwide Dutch Breast Implant Registry.

Variation in the use of infection control measures and infection-related revision incidence after breast implant surgery in the Netherlands.

Background: The use and effect of most infection control measures (ICMs) in breast implant surgery are still debated, likely resulting in undesired variation in current practices.

Objectives: This study investigated the relationship between the number and combinations of ICMs used and the infection-related revision incidence after breast implant surgery. Additionally, national variation between Dutch healthcare institutions in ICM use was evaluated.

Breast cancer recurrence after immediate and delayed postmastectomy breast reconstruction-A systematic review and meta-analysis.

Background: Oncological safety of different types and timings of PMBR after breast cancer remains controversial. Lack of stratified risk assessment in literature makes current clinical and shared decision-making complex. This is the first systematic review and meta-analysis to evaluate differences in oncological outcomes after immediate versus delayed postmastectomy breast reconstruction (PMBR) for autologous and implant-based PMBR separately.

Sentinel Lymph Node Mapping in Breast Cancer Patients Through Fluorescent Imaging Using Indocyanine Green: The INFLUENCE Trial.

Objective: The aim was to compare the (sentinel) lymph node detection rate of indocyanine green (ICG)-fluorescent imaging versus standard-of-care 99m Tc-nanocoilloid for sentinel lymph node (SLN)-mapping.

Background: The current gold standard for axillary staging in patients with breast cancer is sentinel lymph node biopsy (SLNB) using radio-guided surgery using radioisotope technetium ( 99m Tc), sometimes combined with blue dye. A promising alternative is fluorescent imaging using ICG.

Most patients reported positively or neutrally of having served as controls in the trials within cohorts design.

Objectives: To evaluate patients' experience of having served as controls without a notification at the time of randomization in the context of the trial within cohorts (TwiCs) design.

Methods: Patients were asked for their opinion on having served as controls in TwiCs, before and after having been provided the trial results. Patients had provided broad consent to randomization at cohort entry and had served as controls in one of two TwiCs (an exercise program after breast cancer treatment or radiotherapy dose-escalation for rectal cancer).

The impact of the COVID-19 pandemic on perceived access to health care and preferences for health care provision in individuals (being) treated for breast cancer.

Purpose: To evaluate perceived access to health care and preferences for health care provision among patients (being) treated for breast cancer during the COVID-19 pandemic.

Methods: Longitudinal study within the prospective, multicenter UMBRELLA cohort of patients (being) treated for breast cancer. All cohort participants enrolled in UMBRELLA between October 2013 and November 2020 were sent a COVID-19-specific survey during the first and second wave of the COVID-19 pandemic, i.

Clinical characteristics associated with pain in patients with peripheral vascular malformations.

Objective: Vascular malformations (VM) can negatively impact the patient's quality of life (QoL). Pain is a common problem in these patients. The aim of this study was to investigate risk factors associated with pain and to assess how pain affects QoL.

Using a Digital Implant Catalog Improves Data Quality and Reduces Administrative Burden in the Dutch Breast Implant Registry.

Background: Correct registration of implant characteristics is essential to monitor implant safety within implant registries. Currently, in the nationwide Dutch Breast Implant Registry (DBIR), these characteristics are being registered manually by plastic surgeons, resulting in administrative burden and potentially incorrect data entry.

Objectives: This study evaluated the accuracy of manually registered implant data, possible consequences of incorrect data, and the potential of a Digital Implant Catalog (DIC) on increasing data quality and reducing the administrative burden.

(Ex-)breast cancer patients with (pre-existing) symptoms of anxiety and/or depression experience higher barriers to contact health care providers during the COVID-19 pandemic.

Purpose: To identify factors associated with (perceived) access to health care among (ex-)breast cancer patients during the COVID-19 pandemic.

Methods: Cross-sectional study within a large prospective, multicenter cohort of (ex-)breast cancer patients, i.e.

Impact of the COVID-19 Pandemic on Patient-Reported Outcomes of Breast Cancer Patients and Survivors.

Background: The coronavirus disease 2019 (COVID-19) pandemic (officially declared on the March 11, 2020), and the resulting measures, are impacting daily life and medical management of breast cancer patients and survivors. We evaluated to what extent these changes have affected quality of life, physical, and psychosocial well-being of patients previously or currently being treated for breast cancer.

Methods: This study was conducted within a prospective, multicenter cohort of breast cancer patients and survivors (Utrecht cohort for Multiple BREast cancer intervention studies and Long-term evaLuAtion).

Oncology patients were found to understand and accept the Trials within Cohorts design.

Background And Objective: The Trials within Cohorts design aims to reduce recruitment difficulties and disappointment bias in pragmatic trials. On cohort enrollment, broad informed consent for randomization is asked, after which cohort participants can be randomized to interventions or serve as controls without further notification. We evaluated patients' recollection, understanding, and acceptance of broad consent in a clinical oncology setting.

Breast Edema Following Breast-Conserving Surgery and Radiotherapy: Patient-Reported Prevalence, Determinants, and Effect on Health-Related Quality of Life.

Background: The association between lymphedema of the arm and impaired health-related QoL (HR-QoL) has led to changes in clinical practice. However, data on lymphedema of the breast (ie, breast edema) are lacking. We prospectively evaluated patient-reported prevalence and determinants of breast edema and its effect on patient-reported HR-QoL and breast pain.

Compression Vest Treatment for Symptomatic Breast Edema in Women Treated for Breast Cancer: A Pilot Study.

Lymphedema of the breast/chest wall after breast cancer treatment is often associated with pain and reduced quality of life. We conducted a pilot study to evaluate whether the use of a compression vest reduced symptoms of breast/chest wall edema in breast cancer patients. This single-center study included patients ( = 25) with symptomatic breast/chest wall edema with a pain score of ≥3 on the Numerical Rating Scales (range 1-10).

Introducing BREAST-Q Computerized Adaptive Testing: Short and Individualized Patient-Reported Outcome Assessment following Reconstructive Breast Surgery.

Background: The BREAST-Q is a widely used patient-reported outcome instrument measuring health-related quality-of-life and patient satisfaction in breast surgery. Shorter assessment potentially increases patients' willingness to complete scales, but simply offering a shortened version leads to unacceptable loss in measurement precision. The authors aimed to develop a computerized adaptive test (CAT) to shorten the BREAST-Q's Satisfaction with Breasts scale while maintaining reliability of measurement.
