NCT07072780

Brief Summary

This study is a prospective, single-blinded, randomized controlled trial designed to evaluate the effectiveness of low-level laser therapy (LLLT) using two different wavelengths (904 nm and 650 nm) in patients with secondary lymphedema following breast cancer surgery. Participants will be randomly assigned to one of three groups: 904 nm LLLT, 650 nm LLLT, or sham treatment. The primary objective is to assess changes in arm volume and secondary lymphedema-related outcomes following a structured intervention program.

Outcome Measures

Primary Outcomes (2)

  • Change in subcutaneous tissue thickness of the affected upper limb

    Subcutaneous tissue thickness will be measured using B-mode ultrasonography (7.5 MHz linear-array transducer, Siemens Medical Solutions). Measurements will be taken at five predefined anatomical sites of the affected upper limb: (1) midpoint of the wrist crease, (2) medial epicondyle, (3) lateral epicondyle, (4) 10 cm proximal and distal to the elbow joint along predefined lines on both medial and lateral sides, and (5) the web space between the first and second fingers. Thickness values will be used to assess local soft tissue changes in response to treatment.

    Baseline and after 10 sessions (approximately 3 weeks)

  • Change in dermal backflow (DB) pattern on indocyanine green (ICG) lymphography

    Indocyanine green (Diagnogreen, 2.5 mg/mL) will be injected intradermally into the first and third web spaces of the affected hand (0.1 mL per site). To minimize discomfort, lidocaine HCl 2% with epinephrine (1:100,000) will be administered prior to injection. Lymphatic flow will be visualized using near-infrared fluorescence imaging. Dermal backflow patterns will be classified from Type I to Type V according to established staging criteria, reflecting the severity and distribution of lymphatic stasis. The DB stage will be used as an indicator of lymphatic dysfunction and treatment response.

    Baseline and after 10 sessions (approximately 3 weeks)

Secondary Outcomes (2)

  • Change in extracellular fluid (ECF) ratio

    Baseline and after 10 sessions (approximately 3 weeks)

  • Change in upper limb volume

    Baseline and after 10 sessions (approximately 3 weeks)
