Patient case: 55-year-old male with Melanoma. Genetic variant: NRAS (Q61K). Other conditions: Hypertension.

Clinical trial: Evaluating the Use of Fibrin Tissue Adhesive in Melanoma Patients

Summary: Primary Objective:
  1. To determine whether the use of a fibrin sealant applied to superficial groin soft tissues following node dissection can result in decreased cumulative postoperative drainage, earlier drain removal, and lower incidence of seroma.
  Secondary Objectives:
  1. To determine the postoperative morbidity rate using fibrin sealant following superficial groin dissection.
  2. To assess patient-valuation of outcome by performing a cost-benefit analysis using a willingness-to-pay model.
  3. To determine if serum levels, lymphatic fluids level, or cutaneous expression of vascular endothelial growth factor-D (VEGF-D), vascular endothelial growth factor-C (VEGF-C) or their receptor, vascular endothelial growth factor receptor-3 (VEGFR-3) correlates with nodal tumor burden or development of lymphedema in patients with melanoma.

Detailed description: Patients in this study are scheduled to have groin dissection as part of their surgery for treatment of their melanoma.
  Within 2 weeks before entry into the study, patients will have a complete physical exam and medical history.
  These patients will be randomly assigned (as in the toss of a coin) to one of two groups. Patients in one group will receive TISSEEL applied externally to the dissected groin area. Patients in the other group will receive no fibrin sealant.
  For patients who are admitted to the hospital, the surgical site will be monitored by the surgeon for evidence of wound complications in the first 24 hours after surgery. At the time of discharge from the hospital, patients will be instructed in drain care and how to measure the drainage each day until the drain is removed.
  The contents of the drain will be collected from patients during the first day after surgery, during the first return follow-up visit to M.D. Anderson Cancer Center, and during drain removal.
  Follow-up wound exams will be performed by the local primary physician or in the M.D. Anderson Melanoma Clinic between 1-4 weeks and 6 weeks after surgery. Participation will be over after the 6-week follow-up.
  This is an investigational study. The sealant is FDA approved, though its use in this study is experimental. About 58 patients will take part in this study. All will be enrolled at M. D. Anderson.

Eligibility: Inclusion Criteria:
  -  Part I - Inclusion Criteria Patients that consent to participate.

  -  Patient has used aspirin or other anti-platelet drug (excluding Celebrex) within seven days of operation.
  -  Patients with pre-existing lymphedema.
  -  Patients with other pre-existing medical conditions as per the discretion of the principal investigator.
