Aspergillus sinusitis in cancer patients.

A F Viollier, D E Peterson, C A De Jongh

    Cancer
    |July 15, 1986
    PubMed
    Summary

    Aspergillus sinusitis impacts immunosuppressed cancer patients, often linked to neutropenia and antibiotics. While treatable with amphotericin B, infections frequently recur with cancer relapse.

    Area of Science:

    • Medical Mycology
    • Oncology
    • Infectious Diseases

    Background:

    • Paranasal sinusitis is a significant complication in immunosuppressed cancer patients.
    • Aspergillus species are common fungal pathogens in this vulnerable population.

    Purpose of the Study:

    • To investigate the incidence, predisposing factors, and treatment outcomes of Aspergillus sinusitis in cancer patients.
    • To identify risk factors and recurrence patterns associated with this fungal infection.

    Main Methods:

    • Retrospective analysis of 52 immunosuppressed cancer patients over 5 years.
    • Identification of Aspergillus species from sinus cultures.
    • Evaluation of clinical data including granulocyte counts, hospitalization duration, and antibiotic therapy.

    Main Results:

    • Twenty-one patients were diagnosed with Aspergillus sinusitis.
    • Key predisposing factors included prolonged neutropenia (granulocyte count < 500/microliter), extended hospitalization, and prolonged antibiotic use.
    • Initial treatment with amphotericin B was successful in 18 of 21 patients, but 11 experienced recurrence, often coinciding with tumor progression.

    Conclusions:

    • Aspergillus sinusitis in cancer patients is associated with prolonged neutropenia and antibiotic exposure.
    • The infection is treatable but prone to recurrence, particularly during malignancy exacerbation.
    • Early diagnosis and management are crucial, alongside addressing underlying immunosuppression and malignancy.
