Clinical Scorecard: Outcomes of the PräVAC Study: Reducing Wound Complications After Inguinal Lymph Node Dissection in Penile Cancer Patients Through Epidermal Vacuum-Assisted Closure

At a Glance

Key Highlights

• Inguinal lymphadenectomy is recommended for staging and treatment in penile cancer patients with intermediate/high risk or clinically suspicious lymph nodes but is associated with high wound morbidity (25–70%)
• Epidermal vacuum wound dressing (VAC) significantly reduces lymphocele formation, persistent lymphorrhea, and lymphedema compared to conventional wound care
• The PräVAC study is a prospective, randomized, multicenter trial confirming the benefits of epidermal vacuum therapy in reducing wound complications after inguinal lymph node dissection

Guideline-Based Recommendations

Diagnosis

• Perform surgical lymph node staging (dynamic sentinel node biopsy or modified inguinal lymphadenectomy) in penile cancer patients with ≥ pT1 G2 tumors
• Radical inguinal lymphadenectomy advised for clinically suspicious inguinal lymph nodes

Management

• Use epidermal vacuum wound dressing (e.g., PREVENA™ Incision Dressing) on closed inguinal wounds post-lymphadenectomy to reduce wound complications
• Prefer ligation over diathermic coagulation during surgery to reduce morbidity
• Apply subcutaneous suction drain and pressure dressing in conventional care; epidermal vacuum therapy includes suction drain plus vacuum dressing

Monitoring & Follow-up

• Remove epidermal vacuum dressing after 7–8 days; remove pressure dressing after 24 hours in conventional care
• Remove suction drainage when daily fluid volume is < 25 ml but not before postoperative day 3
• Perform bilateral inguinal sonography before hospital discharge to assess wound status
• Document wound complications during hospital stay and assess patient pain and satisfaction using visual analogue scales

Risks

• High morbidity associated with inguinal lymphadenectomy includes prolonged lymph secretion, lymphocele formation, wound dehiscence, and lymphedema
• Avoidance of inguinal lymphadenectomy due to morbidity risk leads to higher mortality in penile cancer patients

Patient & Prescribing Data

Penile cancer patients undergoing bilateral inguinal lymphadenectomy or dynamic sentinel node biopsy

Epidermal vacuum therapy applied on one groin side and conventional care on the other within the same patient allows direct comparison, showing reduced wound complications and reinterventions with vacuum therapy

Clinical Best Practices

• Adhere to EAU guidelines for inguinal lymphadenectomy indications in penile cancer
• Use epidermal vacuum wound dressing postoperatively to minimize lymphatic complications
• Apply randomized side allocation for wound dressing in clinical trials to control patient-specific confounders
• Monitor wound fluid output closely to guide drain removal timing
• Assess patient-reported pain and satisfaction to evaluate wound care effectiveness
