1. Long-term cosmetic outcome after intraoperative radiotherapy boost with low-energy X-rays in breast-conserving therapy: a pooled cohort analysis of the TARGIT-BQR and ROKSM trials.
Pooling two prospective cohorts, objective BCCT.core assessments showed that an IORT boost (20 Gy low-energy X-rays) followed by whole-breast irradiation yields predominantly excellent/good cosmetic outcomes, sustained up to 10 years. TARGIT-BQR patients consistently achieved higher excellent/good ratings than ROKSM across all timepoints.
Impact: Provides rare, objective, long-term multicenter evidence on cosmesis after IORT boost in breast-conserving therapy, informing patient counseling and modality selection.
Clinical Implications: Supports the acceptability of IORT boost from a cosmetic standpoint over up to a decade, aiding shared decision-making regarding boost modalities and long-term expectations.
Key Findings
- Across pooled follow-ups, 61.9% of cosmetic ratings were excellent or good by BCCT.core.
- TARGIT-BQR cohort had significantly more excellent/good ratings than ROKSM (p < 0.0001) at every timepoint.
- Excellent/good cosmetic results were sustained up to 10 years after whole-breast irradiation.
Methodological Strengths
- Prospective multicenter cohorts with standardized photographic timepoints
- Objective, validated cosmetic assessment (BCCT.core) and GEE modeling over time
Limitations
- Nonrandomized pooled cohorts with potential selection and cohort heterogeneity
- No contemporaneous control group without IORT boost; cosmetic determinants not fully explored
Future Directions: Identify patient-, tumor-, and treatment-related predictors of cosmesis and compare IORT boost to alternative boost modalities in prospective controlled designs.
PURPOSE: This study investigates objective long-term cosmetic outcomes in patients with breast cancer after intraoperative radiotherapy applied as a boost (IORT boost) from a pooled international cohort. METHODS: A pooled analysis of two prospective studies with IORT boost (low-energy X‑rays, 20 Gy; inclusion criteria: 3.5 cm maximum tumor size and preoperative indication for a boost according to local criteria) during breast-conserving surgery followed by whole-breast radiotherapy (46-50 Gy). The analysis included photos from a subgroup of the prospective phase IV TARGeted Intraoperative radioTherapy (TARGIT) Boost Quality Registry (BQR) study (NCT01440010) with a follow-up of up to 10 years as well as patients from a Swiss study (ROKSM; Spital Thurgau AG; NCT02114086) with a follow-up of 5 years. The pooled analysis included photos from both trials taken at the same timepoints (6 weeks, 6 months, 1 year, 2 years, and 5 years after completion of whole-breast radiotherapy). Cosmetic results were evaluated with the validated BCCT.core software (BCCT.core 2.0, INESC Porto, Portugal) to assess symmetry, color, and scars. A generalized estimating equation (GEE) regression model was used to compare the two cohorts over time. RESULTS: The pooled analysis included 777 cosmetic assessments from 276 patients. Across all follow-ups in the pooled analysis, the majority of cosmetic results were rated as excellent or good (61.9%). Patients from TARGIT-BQR had significantly more excellent or good ratings than patients from ROKSM (p < 0.0001). The proportion of patients receiving "excellent" and "good" ratings remained higher in TARGIT-BQR than in ROKSM at every timepoint during follow-up. Overall, for up to 10 years, the majority of ratings in the whole cohort were "excellent" or "good." CONCLUSION: In this international pooled analysis, the cosmetic outcome after IORT boost followed by whole-breast irradiation shows a good esthetic long-term outcome. Further studies should explore factors that influence cosmetic outcomes and consider additional treatment-related parameters.
2. Single-port versus multi-port laparoscopic totally Extraperitoneal inguinal hernia repair: a systematic review and Meta-analysis of postoperative outcomes.
Across 23 studies (2894 patients), single-incision TEP modestly prolonged unilateral operative time but improved early pain and cosmetic satisfaction with no differences in complications, hospital stay, or short-to-midterm recurrence versus multi-port TEP. Benefits were attenuated in RCT-only subgroup analyses.
Impact: Synthesizes the best available comparative evidence on patient-centered outcomes (pain, cosmetic satisfaction) and safety, supporting informed surgical choice.
Clinical Implications: SIL-TEP can be offered to patients prioritizing minimal scarring, with an expectation of similar safety and recurrence risk compared to multi-port TEP.
Key Findings
- SIL-TEP increased unilateral operative time by 4.39 minutes (95% CI 0.88–7.89) overall.
- SIL-TEP reduced postoperative day-7 pain (MD −0.57) and improved cosmetic satisfaction (MD 0.77).
- No significant differences in complications, hospital stay, or recurrence between SIL-TEP and multi-port TEP.
Methodological Strengths
- Comprehensive meta-analysis including 7 RCTs and 16 non-RCTs with pooled effect estimates
- Consistent assessment of multiple patient-centered and safety outcomes
Limitations
- Heterogeneity across study designs; advantages were not sustained in RCT-only subgroup
- Cosmetic satisfaction measures and follow-up durations varied; long-term cosmesis and recurrence remain uncertain
Future Directions: Standardize cosmetic outcome measures and conduct adequately powered RCTs with long-term follow-up to assess durability of benefits.
BACKGROUND: Single-incision laparoscopic totally extraperitoneal inguinal hernia repair (SIL-TEP) has gained attention for its potential to minimize surgical trauma and improve cosmesis. However, its comparative efficacy and safety versus conventional multi-port laparoscopic totally extraperitoneal repair (MTL-TEP) remain contentious. OBJECTIVE: This meta-analysis aimed to systematically evaluate the feasibility and safety of SIL-TEP compared to MTL-TEP. METHODS: A systematic literature search was conducted in databases including PubMed, Embase, and the Cochrane Library from January 2005 to June 2025. Data on postoperative outcomes were extracted and pooled for meta-analysis. Statistical analyses were performed using RevMan 5.4, calculating mean differences (MD) or odds ratios (OR) with 95% confidence intervals (CI). RESULTS: Analysis of 23 studies (7 RCTs, 16 non-RCTs; 2894 patients) showed SIL-TEP had a longer unilateral operative time (MD = 4.39 min, 95% CI: 0.88-7.89, P = 0.01), though this was not significant in study design subgroup analysis. SIL-TEP offered superior early outcomes, including lower pain scores on postoperative day 7 (MD = -0.57, 95% CI: -1.09 to -0.05, P = 0.03) and higher cosmetic satisfaction (MD = 0.77, 95% CI: 0.27-1.28, P = 0.002). The techniques were comparable in bilateral operative time, overall complications (OR = 0.92, P = 0.48), hospital stay (MD = -0.02, P = 0.50), and recurrence rates (OR = 0.81, P = 0.65). CONCLUSION: This meta-analysis suggests that SIL-TEP is a safe and feasible alternative to MTL-TEP. The pooled results indicate potential benefits of SIL-TEP in reducing early postoperative pain and achieving better cosmetic outcomes, although these advantages were not sustained in the RCT subgroup analysis. Critically, both techniques demonstrated comparable safety profiles, with no significant differences in complication rates, hospital stay, and short-to-midterm recurrence risk. SIL-TEP represents a viable surgical option that can be individualized for patients, particularly those who place a high value on minimal scarring.
3. Cosmetic Adverse Reactions and Prognostic Factors: A Retrospective Cohort Study in Wuhan, China.
In a 7,794-case multi-source retrospective cohort, 23.44% of cosmetic adverse reactions resulted in persistent or permanent sequelae. Younger age (<20 years) and histories of food or drug allergy significantly increased the risk of long-term skin damage (e.g., PIH, atrophic scarring).
Impact: Defines prognostic risk factors for persistent cutaneous sequelae after cosmetic adverse reactions at population scale, enabling risk-stratified prevention and counseling.
Clinical Implications: Screen adolescents and patients with allergy histories for higher risk; emphasize early intervention and cautious use of new products, potentially including patch testing and tailored counseling.
Key Findings
- 76.56% achieved complete recovery; 23.44% had persistent/permanent sequelae (e.g., PIH, atrophic scarring).
- Age <20 years increased risk of long-term damage vs. >50 years (OR 2.06; p=0.000).
- Food allergy history (OR 3.16; p<0.05) and drug allergy history (OR 1.887; 95% CI 1.34–2.66; p=0.000) were significant predictors.
Methodological Strengths
- Large multi-source dataset (n=7,794) spanning 2017–2023 with multivariable logistic regression
- Systematic stratification by recovery outcome to identify prognostic factors
Limitations
- Retrospective design with potential reporting and selection biases; exposure details and product heterogeneity limit causal inference
- Follow-up duration and standardized outcome adjudication are not uniform across cases
Future Directions: Prospective surveillance with standardized exposure and outcome measures to validate risk models and test preventive strategies in high-risk subgroups.
BACKGROUND: Despite the increasing prevalence of cosmetic-related adverse reactions, their potential prognoses and associated risk factors have received limited attention within the medical community. METHODS: A retrospective analysis was conducted on 7794 cases of cosmetics-related adverse reactions reported in Wuhan, China, from 2017 to 2023. Data were collected from multiple sources, including medical institutions, cosmetic manufacturers, distributors, individual consumers and regulatory agencies. Demographic characteristics, clinical diagnoses, symptom profiles and allergy histories were systematically analysed using descriptive statistics. Cases were stratified by recovery outcome into complete versus incomplete groups to identify prognostic factors. Comparative analyses were performed using χ2 tests, with statistically significant variables (p < 0.05) further evaluated through multivariate logistic regression to calculate odds ratios (ORs) and 95% confidence intervals (CIs). All statistical analyses were performed using SPSS version 25.0, with a significance level set at p < 0.05. RESULTS: Among the 7794 patients, the majority (76.56%) achieved complete recovery, while a substantial proportion (23.44%) experienced persistent or permanent symptoms, such as post-inflammatory hyperpigmentation (PIH), atrophic scarring and other forms of skin damage. Statistical analysis identified age and a history of allergies as significant risk factors for long-term skin damage. Patients under 20 years of age were 2.06 times more likely to suffer persistent or permanent symptoms compared to those over 50 years (p = 0.000). Additionally, individuals with a history of food allergy were 3.16 times more prone to long-term skin damage (p < 0.05). A history of drug allergy also significantly increased the risk, with an OR of 1.887 (95% CI: 1.34, 2.66; p = 0.000). CONCLUSION: This study identified younger age (< 20 years) and a history of food or drug allergies as significant risk factors for long-term symptoms following cosmetic adverse reactions. These insights assist dermatologists in recognising high-risk individuals and guiding tailored preventive strategies. Integrating these indicators into clinical evaluation and patient counselling may enhance early intervention, ultimately reducing the likelihood of persistent or irreversible cutaneous sequelae. Overall, the findings highlight the importance of individualised risk assessment and proactive management in ensuring cosmetic safety and optimising dermatological and public health outcomes.
