LYMPHA procedure to prevent arm lymphedema after axillary lymph node removal

Official title: A Randomized Clinical Trial of the LYMPHA Procedure for the Prevention of Lymphedema After Axillary Lymphadenectomy

Run by Stanford University · NCT05366699 · Data updated 2026-11-12

This trial will try adding the LYMPHA lymphatic reconstruction at the time of axillary lymph node removal to see if it lowers the risk of lymphedema in adults having lymphadenectomy for breast cancer.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–75 undergoing unilateral or bilateral breast-cancer-related axillary lymphadenectomy who do not have preexisting lymphedema or distant metastases and who can provide informed consent and attend follow-up at the study site.

Probably not a fit

Patients with existing upper-limb lymphedema, prior axillary radiation, an allergy to porcine collagen or ICG, or those unable to complete required follow-up visits are unlikely to benefit from enrollment.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Adults undergoing breast-cancer-related axillary lymphadenectomy at Stanford will receive one of three operative approaches: immediate LYMPHA lymphatic reconstruction, lymphadenectomy alone, or lymphadenectomy with soft tissue reinforcement. The study will compare rates of new-onset lymphedema using objective limb measurements alongside patient-reported quality-of-life outcomes. Eligible participants are 18–75 years old without preexisting lymphedema or distant metastases and must be able to consent and complete follow-up visits. Patients with prior axillary radiation, known allergy to porcine collagen or ICG, or recent/impending nodal radiation are excluded.

Why it matters

Potential benefit: If successful, the LYMPHA procedure could reduce the chance of developing arm lymphedema and improve arm function and quality of life after lymph node removal.

How similar studies have gone: Smaller single-center and observational reports have suggested LYMPHA can lower post-axillary dissection lymphedema rates, but high-quality randomized evidence is still limited.

* Receiving radiation therapy to the involved nodal basin in a period less than 4 weeks after the surgery
* Concurrent participation in a clinical trial of any other investigational drug or therapy, regardless of indication, within 1 month before screening
* Other medical condition that could lead to limb edema, such as (but not limited to primary lymphedema or acute venous thrombosis
* Other medical condition that could result in symptoms overlapping those of lymphedema in the affected limb (e.g., pain, swelling, decreased range of motion)
* Either of the following, at the time of baseline evaluation: ipsilateral:contralateral limb volume ratio\>1.1 or R0 bioimpedance ratio \> 1.106 when the nondominant limb is at risk, and 1.134 when the dominant limb is at risk.

* Absolute neutrophil count \< 1500 mm3 at screening
* Hemoglobin concentration \< 9 g/dL at screening
* Any reason (in addition to those listed above) that, in the opinion of the investigator, precludes full participation in the study
