Three impactful papers span oncologic radiotherapy, ethics in aesthetic gynecology, and biomaterials testing. A large prospective analysis supports simultaneous integrated boost (SIB) as an efficient alternative to sequential boost in hypofractionated whole-breast irradiation with comparable control, toxicity, and cosmetic outcomes. FIGO issues an ethical statement against cosmetic genital surgery due to insufficient evidence, and a rheology study proposes a standardized protocol to assess hyaluronic acid filler degradability.

1. Comparison of simultaneous integrated tumor bed boost and sequential boost during hypofractionated whole-breast irradiation after breast-conserving surgery.
In 1,132 patients receiving hypofractionated whole-breast irradiation, SIB achieved similar 5-year local control, toxicity, and cosmetic outcomes compared with SeB while reducing overall treatment time. These findings support SIB as an efficient alternative to sequential boosts.
Impact: This large prospective analysis addresses oncologic control and cosmetic outcomes while enabling shorter treatment courses, an important operational and patient-centered advantage.
Clinical Implications: Clinicians can consider adopting SIB (49.5 Gy/15 to the tumor bed with 43.5 Gy/15 to whole breast/nodes) to shorten treatment without sacrificing outcomes. Longer-term fibrosis, cosmesis, and patient-reported outcomes should guide patient selection.
Key Findings
- Two prospective cohorts (n=1,132) compared SIB (n=775) vs SeB (n=357) with standardized hypofractionated dosing.
- Five-year local control was comparable (97.8% vs 98.8%); toxicity and cosmetic outcomes were similar.
- SIB reduces total treatment duration relative to SeB.
Methodological Strengths
- Large sample size with prospective data from two studies
- Predefined dosing schema and inclusion of cosmetic outcomes
Limitations
- Non-randomized design may introduce selection bias
- Long-term cosmetic and fibrosis outcomes beyond 5 years are not yet reported
Future Directions: Randomized trials or longer follow-up with granular cosmetic and patient-reported outcomes are needed to confirm durable equivalence and refine selection criteria.
BACKGROUND AND PURPOSE: This study aimed to compare the safety and efficacy of simultaneous integrated boost (SIB) and sequential boost (SeB) during hypofractionated WBI. MATERIALS AND METHODS: This study analyzed data from two prospective studies, including 1,132 patients with pT1-3 N0-3 M0 breast cancer, of whom 775 received SIB and 357 received SeB. The prescribed dose was 43.5 Gy in 15 fractions to whole breast and/or nodal region, with either 49.5 Gy in 15 fractions (SIB) or 8.7 Gy in 3 fractions (SeB) delivered to tumor bed. Outcomes analyzed included survival outcomes, treatment-related toxicities, and cosmetic outcomes. RESULTS: The 5-year outcomes were local control rates of 97.8 % vs. 98.8 % ( CONCLUSION: SIB is a viable alternative to SeB, offering comparable toxicity profiles and survival outcomes while shortening treatment duration. Longer follow-up is warranted to assess long-term outcomes.
2. FIGO statement: Cosmetic genital surgery.
FIGO states that cosmetic genital surgery lacks robust evidence of safety and efficacy and is ethically inappropriate for obstetrician-gynecologists to recommend, perform, or refer. The statement highlights insufficient data for laser-based devices used for genitourinary syndrome of menopause or cosmetic purposes and emphasizes counseling and informed decision-making.
Impact: Provides authoritative global ethical guidance in a rapidly expanding but poorly regulated cosmetic domain, prioritizing patient safety and evidence-based practice.
Clinical Implications: Ob-gyns should avoid recommending or performing cosmetic genital procedures and should counsel patients on the lack of medical indication and potential risks. For genitourinary syndrome of menopause, prioritize evidence-based therapies rather than laser devices lacking robust safety/efficacy data.
Key Findings
- Evidence supporting safety and efficacy of cosmetic genital surgery is limited.
- FIGO deems it ethically inappropriate for ob-gyns to recommend, perform, or refer for such procedures.
- Insufficient research supports laser-based devices for genitourinary syndrome of menopause or cosmetic use; counseling and accurate information are essential.
Methodological Strengths
- International consensus statement from FIGO
- Clear ethical guidance emphasizing evidence gaps and patient counseling
Limitations
- Not a systematic review; lacks quantitative risk-benefit analysis
- Applicability may vary by legal and cultural context
Future Directions: Prospective studies and randomized trials are needed to evaluate safety/efficacy; development of standardized outcomes and ethical frameworks across regions is warranted.
Cosmetic genital surgery refers to various procedures that involve surgical alteration of the vulvovaginal anatomy for aesthetic reasons in women without structural or functional abnormalities. The growing demand for such procedures stems from exposure to media and online content that reinforced the notion that certain genital appearances do not conform to an idealized aesthetic standard. There is, however, a lack of strong evidence and limited published research to support the claim that cosmetic genital surgery is safe and effective. FIGO asserts that it is ethically inappropriate for obstetrician-gynecologists to recommend, perform, or refer patients for these procedures. Women should receive counseling and be informed that these procedures are not medically indicated and come with potential risks. Of special concern is the use of laser-based devices for treating the genitourinary syndromes of menopause or for cosmetic purposes. There is insufficient research data to support the safety and effectiveness of these devices. By addressing ethical concerns and ensuring that accurate information is provided, healthcare professionals can support women in making well-informed choices about cosmetic genital surgery.
3. Rheology as a Tool to Investigate the Degradability of Hyaluronic Acid Dermal Fillers.
Using rotational rheology, the authors quantified hyaluronidase-mediated degradation of HA fillers, showing dose- and time-dependent changes in viscoelastic parameters. They propose a standardized protocol to assess filler degradability, offering an objective alternative to current approaches.
Impact: Provides a reproducible laboratory method to compare product degradability and inform hyaluronidase use in managing complications, addressing a key safety gap in aesthetic practice.
Clinical Implications: Standardized rheological testing could guide filler selection in high-risk areas and inform hyaluronidase dosing strategies; clinical validation against in vivo dissolution and outcomes is needed before routine adoption.
Key Findings
- Rotational rheology correlates viscoelastic changes with hyaluronidase-mediated degradation of HA fillers.
- Rheological parameters vary with enzyme contact time and dose, indicating product sensitivity to hyaluronidase.
- A standardized rheological protocol is proposed as an alternative method for degradability assessment.
Methodological Strengths
- Objective, quantitative biomechanical readouts
- Dose- and time-response characterization enabling standardization
Limitations
- In vitro methodology without direct clinical outcome correlation
- Limited range of products and no inter-batch variability analysis reported
Future Directions: Correlate rheological degradability metrics with in vivo dissolution and clinical outcomes; expand to diverse crosslinking chemistries and share datasets/code for reproducibility.
BACKGROUND: In the current landscape of aesthetic medicine, the use of hyaluronic acid (HA)-based dermal fillers is increasingly prevalent. Although HA is widely acknowledged for its safety and efficacy the study of its degradability represents a critical aspect in ensuring safety. METHODS: Rotational rheology was chosen to study the HA-based fillers interaction with hyaluronidase enzyme; this allows to establish a correlation between the viscoelastic parameters of the sample and its degradation. RESULTS: The obtained results indicate that the products exhibit sensitivity to the enzyme and that the rheological parameters vary depending on the contact time and dosage of administration. CONCLUSION: Our findings propose a standardized rheological protocol for assessing the degradability of HA-based dermal fillers, offering an alternative to existing methods.
