1. Beauty Is in the Eye of the Beholder: Cosmetic Outcomes After Precision Breast Intraoperative Radiation Therapy.
In a phase II cohort of 357 PB-IORT patients with up to 24 months follow-up, 88.7% of patients rated cosmesis as good/excellent, with clinicians and a plastic surgeon rating 93.7% and 80.3% similarly. Interrater agreement was low (Kappa <0.40), emphasizing the primacy of patient-reported outcomes for cosmetic assessment.
Impact: Demonstrates that PB-IORT maintains favorable cosmetic outcomes while revealing poor interrater reliability, reshaping how cosmetic endpoints should be measured in breast surgery.
Clinical Implications: PB-IORT can deliver a single high-dose treatment without compromising cosmesis; cosmetic assessment should prioritize patient-reported outcomes. Clinicians should counsel patients on likely cosmetic results and incorporate standardized PRO measures.
Key Findings
- At 24 months, 88.7% of patients rated cosmesis as excellent/good; clinicians and a plastic surgeon rated 93.7% and 80.3%, respectively.
- Interrater reliability across patients, clinicians, and the plastic surgeon was minimal (Kappa <0.40).
- PB-IORT delivers a single high dose of radiation without compromising cosmetic outcomes.
Methodological Strengths
- Prospective data collection within a phase II clinical trial
- Multiple independent raters using a validated cosmesis scale with interrater analysis
Limitations
- No randomized comparator; lack of direct comparison with standard whole-breast irradiation
- Follow-up limited to 24 months; long-term cosmetic durability unknown
Future Directions: Include PROs as primary endpoints in comparative trials versus standard radiotherapy, extend follow-up beyond 5 years, and evaluate predictors of cosmetic outcomes.
INTRODUCTION: Precision Breast Intraoperative Radiation Therapy (PB-IORT) is a novel form of IORT that combines computed tomography-guided treatment planning with high-dose-rate brachytherapy to deliver individualized radiation that spares the skin and chest wall. We analyzed cosmetic outcomes following PB-IORT as scored by breast clinicians, a plastic surgeon, and patients, and assessed the interrater reliability between the scores. METHODS: As part of a phase II clinical trial, the study cohort included 357 patients treated with PB-IORT who had up to 24 mo of follow-up data. At each follow-up visit, the patient, plastic surgeon, and breast clinicians completed the Harvard Cosmesis Scale and a survey that evaluates changes in breast pigmentation, shape, and size. Interrater agreement was assessed using Kappa statistics. RESULTS: At 24 mo, 88.7% (95% confidence interval [CI]: 84.77, 92.61) of patients rated their cosmesis as "excellent" or "good' with the Harvard Cosmesis Scale; 93.7% (95% CI: 90.80, 96.14) and 80.3% (95% CI: 75.08, 85.50) of patients were rated similarly by the breast clinicians and the plastic surgeon, respectively. There was minimal agreement between patients, breast clinicians, and the plastic surgeon for all variables (Kappa <0.40). Breast clinicians rated cosmesis the most favorably. CONCLUSIONS: PB-IORT delivers a single, high dose of radiation without compromising cosmetic outcomes. Cosmetic outcome scores from patients, breast clinicians, and the plastic surgeon had low interrater reliability. The patient's perspective is paramount when assessing cosmetic outcomes after breast surgery. We advocate that future studies include patient-reported outcomes as the primary means of evaluating cosmetic outcomes.
2. Comparison of clinical effectiveness between tissue adhesives and sutures for wound closure in periodontal flap surgery: a systematic review and meta-analysis.
Registered (PROSPERO) PRISMA-compliant synthesis of prospective trials found no significant difference in wound healing between tissue adhesives and sutures after periodontal flap surgery, amid high heterogeneity. Tissue adhesives may offer comparable or better cosmetic outcomes and patient satisfaction.
Impact: Establishes evidence-based parity of tissue adhesives with sutures for periodontal flap closure, informing practice where cosmetic outcomes and efficiency matter.
Clinical Implications: Tissue adhesives are a reasonable alternative to sutures for periodontal flap closure, potentially reducing procedure time and pain while maintaining healing and cosmetic outcomes. Clinicians should consider patient preference and surgical context.
Key Findings
- Meta-analysis found no significant mean difference in wound healing between tissue adhesives and sutures, despite high heterogeneity.
- Most included studies had a low risk of bias, supporting reliability of findings.
- Conclusions suggest tissue adhesives may match or surpass sutures in cosmetic outcomes and patient satisfaction.
Methodological Strengths
- PROSPERO-registered, PRISMA 2020-compliant methodology
- Comprehensive multi-database search with qualitative and quantitative synthesis
Limitations
- High heterogeneity limits pooled estimates and generalizability
- Variable study designs and follow-up periods across included trials
Future Directions: Conduct large, standardized randomized trials directly comparing adhesives versus sutures with harmonized endpoints, including cosmetic outcomes and patient-reported measures.
BACKGROUND: Although traditional sutures are efficient, they can result in complications such as infection and scarring. On the other hand, tissue adhesives have the potential to provide advantages such as reduced application time and postoperative pain. Understanding the comparative outcomes of various procedures can have a substantial impact on clinical periodontal surgery. This systematic review and meta-analysis (PROSPERO CRD42023444615) is designed to synthesize existing research and provide insights into optimizing wound closure procedures for better patient outcomes. The aim of the present systematic review and meta-analysis is to compare the efficacy of tissue adhesives with sutures on wound healing in periodontal flap surgery. MATERIALS AND METHODS: By adhering to PRISMA 2020 standards, the review outlined systematic processes for identifying and selecting relevant studies, which involved an extensive search across databases such as PubMed, Cochrane Library, Embase, Scopus, Web of Science, Google Scholar, and trial registries. The inclusion criteria focused on all prospective human trials conducted between January 2013 and June 2023, allowing for a diverse range of study designs, including randomized controlled trials, clinical trials, non-randomized trials, and split-mouth trials. Ultimately, 10 and 8 studies were included for qualitative synthesis and quantitative analysis, respectively, with data on the degree of wound closure/healing aggregated from studies that shared similar follow-up periods. Forest plots were created appropriately allowing for a clearer interpretation of the comparative outcomes between tissue adhesives and sutures. RESULTS: The assessment of the included studies revealed that most demonstrated a low risk of bias in their methodologies, indicating reliable and robust research practices. However, the forest plot analysis indicated no significant mean difference in the degree of wound healing between tissue adhesives and sutures, despite a high level of heterogeneity ( CONCLUSION: Wound healing with tissue adhesives appears to be better or comparable to that of sutures in periodontal flap surgery. Tissue adhesives may be a non-invasive alternative to sutures in terms of cosmetic outcome and patient satisfaction. Further randomized trials with larger samples and following standard protocols should be undertaken for their clinical use in periodontal flap surgery.

3. Standardizing Tissue Preservation in Breast-Conserving Surgery: Ultrasound Guidance Reduces Resection Volumes by 40% Compared to Palpation.
In a retrospective cohort (n=114), ultrasound-guided BCS significantly reduced positive margins (2.2% vs 9.0%), re-excisions (2.6% vs 14.0%), and improved resection efficiency by 40% (CRR 1.8 vs 3.0). Nonpalpable tumors achieved the lowest CRR, supporting US guidance for tissue preservation and cosmesis.
Impact: Quantifies large gains in tissue preservation and oncologic safety with a reproducible metric (CRR), strengthening the case for ultrasound-guided BCS to enhance cosmetic outcomes.
Clinical Implications: Where expertise exists, adopt intraoperative ultrasound guidance to reduce resection volumes and re-excisions, potentially improving cosmetic outcomes. Training and workflow integration are needed; consider nonpalpable tumors as prime candidates.
Key Findings
- Positive margin rate reduced from 9.0% to 2.2% and re-excisions from 14.0% to 2.6% with ultrasound guidance.
- Median calculated resection ratio (CRR) improved from 3.0 to 1.8 (p < 0.001), with 1.6 in nonpalpable tumors.
- For a representative 2 cm tumor, total resection volume reduced by 78% with ultrasound guidance.
Methodological Strengths
- Introduces and applies a quantitative surgical quality metric (CRR)
- Includes both palpable and nonpalpable tumors with multivariate analyses
Limitations
- Retrospective, nonrandomized design with potential selection bias
- Single-center study; multivariate results were nonsignificant
Future Directions: Prospective randomized trials to validate CRR improvements, assess learning curves, and quantify long-term cosmetic outcomes and quality of life.
BACKGROUND: Ultrasound guidance (US) may optimize breast-conserving surgery (BCS) by standardizing resection precision, but comparative quantitative data remain limited. This study evaluates whether US improves margin control and tissue preservation versus palpation-guided BCS using a calculated resection ratio (CRR). METHODS: Retrospective analysis of 114 patients with BCS (37 palpation-guided; 77 US-guided [34 palpable and 43 nonpalpable]). PRIMARY ENDPOINTS: positive margin rates, re-excision rates, and CRR. Statistical analysis included Mann-Whitney U tests (CRR) and multivariate logistic regression. RESULTS: US guidance reduced positive margins by 76% (2.2% vs. 9.0% and p < 0.0001) and re-excisions by 81% (2.6% vs. 14.0%). Resection efficiency improved by 40% (median CRR 1.8 vs. 3.0 and p < 0.001), with nonpalpable tumors achieving the lowest CRR (1.6). For a representative 2 cm tumor, US guidance reduced total resection volumes by 78% (17.6 vs. 81.4 cm CONCLUSIONS: US-guided BCS standardizes tissue preservation, reducing resection volumes by 40% while maintaining oncologic safety. CRR emerges as a replicable metric for surgical quality. Despite nonsignificant multivariate results, the magnitude of improvement supports US adoption where expertise exists.
