Recurrence of Malignant Pleural Effusion Following Pleurodesis: Is There a Difference Between Use of Povidone-Iodine or Cyclophosphamide?
Background: Malignant pleural effusion is associated with poor quality of life. The success of pleurodesis varies with different agents, with talc being the most effective. It is however not available in Nigeria. This study aimed to determine the efficacy of povidone iodine and cyclophosphamide, the two commonly available agents for pleurodesis
Methods: A prospective simple randomized enrollment of consecutive patients with malignant pleural effusion over a five year period (2008- 2012).
Results: Thirty four patients were analyzed with a M:F ratio of 1:2.4. Breast cancer was responsible for almost half (47.1%) of the effusions. Although the povidone iodine group was slightly younger both groups were similar. There was no difference in the effusion recurrence for both groups. Age, duration of symptoms and cancer type were not predictors of recurrence of effusion following pleurodesis.
Conclusions: Both agents are readily available and perform well with minimal side effects. However, povidone iodine being cheaper may be a more affordable alternative.
