Case of the Week - January 20, 2005

55 year old Male

  • Call from cardiac transplant coordinator
  • 55 year old gentleman 5 years post heart transplant for ischemic cardiomyopathy now with abnormal CXR found on yearly screening film
  • Immunosuppressants – cyclosporine, prednisone, (I don’t think he was on azathioprine)

?localized bronchiectasis
Timeline of Post-Transplant Infections:
  • < 4 weeks
    • Nosocomial technical
      • MRSA, candida, aspergillus, aspiration, line infection, C. difficile
      • Nosocomial pthogens, donor-derived recipient colonizers
  • 1-6 months
    • Opportunistic, relapsed, residual activation of latent infection
      • HSV, CMV, HBV, HCV, EBV, listeria, TB, PCP, BK virus, nocardia, toxoplasma, strongyloides, leishmania
      • Period of most intensive immune suppression
  • >6-12 months
    • Community acquired
      • Community acquired pneumonia, aspergillus, dermatophytes, CMV colitis, UTI
      • Common to rare (depends on exposures and net state of immune suppression)

Diagnosis: Squamous Cell Lung Carcinoma

A couple of questions
  • Are heart transplant patients at higher risk for solid organ malignancy?
  • What malignancies are they are higher risk for?

Of note 2002 CDC data with incidence of lung cancer in general population between 67-85/100,000 (0.08%)

Solid Organ Transplant and Malignancy Risk:

  • Higher risks of some malignancies
    • Skin Cancers – Squamous Cell Carcinoma
    • Post Transplant Lymphomas and Lymphoproliferative Disorders (PTLD)
    • Kaposi’s Sarcoma and other sarcomas
    • Cervical Cancer - in situ carcinomas
    • Hepatobiliary carcinomas
    • Ano-genital carcinomas

What about lung cancer?

  • Israel Penn – “most of the common malignancies seen in the general population are not increased in incidence.”
    • Started the Cincinatti Transplant Tumor Registry in 1968. By 1998, tracked > 10000 transplant patients with malignancies
  • Another American Registry
    • Columbia University, from 1977-1994, 571 patients with heart transplants
    • 9 develop lung cancer (1.5%)
  • Multicenter Italian Registry of Heart Transplanted Patients (MIRHT)
    • Mostly agree with Dr. Penn
    • Of 1000 patients with cancer after heart transplant, 31 had non-cutaneous carcinomas
      • 14 patients with lung cancer
  • German Experience: Tenderich et al
    • From 1989 – 1998, 1084 heart transplant patients followed
      • 10% , 114 develop a malignancy
      • Pulmonary neoplasms in 22 patients (15.9%)
        • Overall 2% of all heart transplant patients
  • From France:
    • 756 patients with heart transplants from 1982 – 1998
      • 16 developed lung cancer (2.1%)

Risk factors in heart transplant pts?:

  1. Smoking History > 30 pack years
  2. Male Gender
  3. Age > 50
  4. Controversial if Immunosuppressant regimen plays a role in lung cancer
