Beta-Interferon treatment for malignant effusions showed a 70% objective response rate in patients with genital or mammary cancers. Ovarian cancer patients experienced significant benefits, with Beta-Interferon proving effective at the peritoneal level.

Area of Science:

  • Oncology
  • Pharmacology
  • Immunology

Background:

  • Malignant effusions (pleural or ascitic) are common in advanced cancers.
  • Endocavitary chemotherapy has limitations in drug delivery and concentration.
  • Beta-Interferon is a biologic agent with potential anti-neoplastic effects.

Purpose of the Study:

  • To evaluate the efficacy of endocavitary Beta-Interferon in treating malignant pleural and ascitic effusions.
  • To assess response rates and duration of response in patients with various cancers.
  • To investigate the drug's effectiveness specifically in ovarian cancer and at the peritoneal level.

Main Methods:

  • Thirteen patients with malignant genital or mammary neoplasias and endocavitary effusions were enrolled.
  • Treatment involved intrapleural or intraperitoneal administration of Beta-Interferon.

  • Objective response, complete response, and duration of response were evaluated.

    • Main Results:

    • An overall objective response rate of 70% was observed.
    • Complete responses were achieved in 53.8% of patients.
    • Average response duration exceeded 6 months.
    • Ovarian cancer patients showed 75% objective response (50% CR).

    Conclusions:

    • Endocavitary Beta-Interferon demonstrates significant efficacy in managing malignant effusions.
    • The treatment is particularly effective in ovarian cancer, especially via intraperitoneal administration.
    • Higher drug concentration at the peritoneal site contributes to improved outcomes.
