KEY POINTS
- This multicentre phase III randomized trial enrolled 236 head and neck cancer survivors with no evidence of disease, previously untreated lymphedema, and at least one associated symptom rated ≥4/10. Participants were randomized 1:1 to daily advanced pneumatic compression for 6 months (n=119) or usual care according to institutional practice (n=117).
- Patient-reported symptom improvements achieved during the initial 2 months were maintained through 6 months in both groups, with no clinically important between-group difference on the Vanderbilt Head and Neck Symptom Survey or Lymphedema Symptom Intensity and Distress Survey.
- Internal lymphedema improved significantly on the Modified Patterson Scale in both groups: APCD slope −0.05 (95% CI −0.06 to −0.04; p<0.01) and usual care −0.03 (95% CI −0.04 to −0.02; p<0.01). Of 19 anatomical subsites, the clearest treatment difference was at the base of tongue (OR 0.95, 95% CI 0.92–0.99; p=0.008).
- External lymphedema improved significantly with APCD (p<0.01) but only trended toward improvement with usual care (p=0.06). The number of involved anatomical sites decreased more with APCD (−0.08, 95% CI −0.11 to −0.05; p<0.01), driven mainly by the submental region.
- Digital photography demonstrated improvement by 6 months without a significant between-group difference. CT also showed significant reduction in soft-tissue swelling at 6 months in both groups (p<0.01 each), despite no significant CT change at 2 months.
- Approximately 70% of each group self-reported performing self-care at least five days per week, although device-recorded APCD use suggested that adherence was over-reported. The cohort predominantly had mild-to-moderate lymphedema, clinician assessors were not blinded, and all participating institutions received study funding from the device manufacturer.
CLINICAL TAKEAWAY
Both structured usual care and advanced pneumatic compression can provide durable symptom and anatomical improvement in treatment-naive head and neck lymphedema. APCD produced modest advantages in selected clinician-rated measures, but not in patient-reported symptoms or six-month imaging, so these data support it as an option rather than a clearly superior standard.
