Summary
May’s cosmetic research emphasized procedure safety, formulation-driven improvements in skin quality, and biomaterial-associated immune modulation. High-level syntheses support technique selection, with IMRT reducing chronic hyperpigmentation after breast radiotherapy. A randomized split-face trial showed glycerol-enhanced hyaluronic acid improved pore volume and hydration with good tolerability. Translational data linked breast implants to local and systemic immune activation, suggesting potential effects on cancer immunosurveillance and counseling.
Selected Articles
1. Chronic skin toxicities in breast cancer survivors: a systematic review and meta-analysis of radiotherapy techniques.
Systematic review and meta-analysis of seven studies (n=2418; three RCTs) comparing conventional adjuvant breast RT with modern techniques. IMRT significantly reduced risk of grade ≥2 chronic hyperpigmentation, while long-term cosmetic and HRQoL differences were inconsistent.
Impact: High-level evidence directly guiding technique choice to mitigate chronic pigmentary toxicity while clarifying evidence gaps in long-term cosmesis and QoL.
Clinical Implications: Prefer IMRT when feasible to reduce chronic hyperpigmentation; counsel that durable cosmetic/QoL advantages remain uncertain and standardized reporting is needed.
Key Findings
- IMRT lowered grade ≥2 chronic hyperpigmentation risk (RR 0.39, 95% CI 0.17–0.89).
- Inconsistent long-term differences in cosmesis and HRQoL across studies.
- Seven studies (n=2418) including three RCTs; heterogeneity limits firm conclusions.
2. Superficial Intradermal Injections of Cohesive Polydensified Matrix Hyaluronic Acid Fillers for the Improvement of Facial Pores and Skin Quality: A Split-Face Randomized Study.
Randomized, double-blind split-face trial (n=30; 29 completers) comparing CPM-HA20 vs. CPM-HA20 with glycerol given monthly x3. Both improved pore volume and hydration; glycerol-added formulation achieved a 24.2% greater pore volume reduction at Week 32 with mild transient AEs.
Impact: Demonstrates formulation-level optimization yields measurable aesthetic gains (pore reduction, hydration) with favorable safety — directly actionable for injectors.
Clinical Implications: Consider glycerol-enhanced HA in a series of three superficial intradermal sessions at 4-week intervals for pore concerns; set expectations for mild, transient AEs and durable (~8-month) improvements.
Key Findings
- CPM-HA20G achieved 24.2% greater mean pore volume reduction vs. CPM-HA20 at Week 32 (p=0.038).
- Both arms improved skin hydration through Week 32.
- Adverse events were mild and transient; satisfaction similar between sides.
3. Breast Implants Elicit Local and Systemic Immune Response: Evidence for Breast Cancer Immunosurveillance.
Case–control human study comparing implant-naive (n=117) and implant-exposed (n=71) women showed higher serum antibodies to tumor-associated antigens and tissue signatures of B/T-cell activation in implant-exposed patients, suggesting peri-implant inflammation extends into breast parenchyma.
Impact: Provides mechanistic human evidence linking implants to immune activation and anti-tumor antigen responses, informing counseling and future longitudinal research.
Clinical Implications: Inform patients that implants may modulate immune markers; no screening changes are indicated yet, but findings support monitoring and research on cancer risk/surveillance implications.
Key Findings
- Higher antibodies to MUC1, ER-α, and mammaglobin A in implant-exposed patients.
- RNA-seq signatures indicate B/T-cell activation and chemotaxis/estrogen response pathway upregulation.
- Peri-implant inflammation likely extends into breast parenchyma.
