Intraperitoneal chemotherapy together with cytoreductive surgery is the standard
of care for a number of peritoneal surface malignancies. However, this approach
fails to maintain the complete response and disease recurs due to microscopic
residual disease. Although safer than systemic chemotherapy regimens,
locoregional treatment with chemotherapeutics can induce toxicity which is a
major concern affecting the patient's treatment protocol and outcome. For an
enhanced treatment efficacy, efforts should be made to maximize cytotoxic effects
of chemotherapeutic agents on tumor cells while minimizing their toxic effects on
host cells. Bromelain and N-acetylcysteine are two natural agents with good
safety profiles shown to have anti-cancer effects. However, their interaction
with chemotherapeutics is unknown. In this study, we investigated if these agents
have the potential to sensitize in vitro gastrointestinal cancer models to
cisplatin, paclitaxel, 5-fluorouracil, and vincristine. The drug-drug interaction
was also analyzed. Our findings suggest that combination of bromelain and
N-acetylcysteine with chemotherapeutic agents could give rise to an improved
chemotherapeutic index in therapeutic approaches to peritoneal surface
malignancies of gastrointestinal origin so that maximum benefits could result
from less toxic and more patient-friendly doses. This represents a potentially
efficacious strategy for the enhancement of microscopic cytoreduction and is a
promising area for future research.
