Bolus versus 5-day continuous infusion of cisplatin with mitomycin and vindesine in the treatment of advanced non-small cell lung cancer (NSCLC): a phase III prospective randomised trial of the Italian Oncology Group for Clinical Research (GOIRC)

How many cisplatin administration protocols does your department use?

The introduction, 30 years ago, of the co-administration of appropriate hydration and ensuring a diuresis occurs during the administration of cisplatin was important in its development, allowing clinically significant doses to be given with acceptable rates of toxicity. The clinical usage of cisplatin has increased and hydration protocols have been amended to increase patient comfort and reduce resource utilization. We suspected that this had led to unnecessary variations in practice both in clinical trials and subsequently in the clinic. Therefore, we reviewed practice in the Edinburgh Cancer Centre and discovered that 25 different hydration protocols were in use, with wide variation in dilution of cisplatin, total fluid administered, use of electrolyte (potassium and magnesium) supplementation and diuretics. These differences are a reflection of adoption of variations in hydration regimes published in pivotal clinical trials. A review of the available evidence relating to cisplatin associated hydration regimens was performed and recommendations will be made for the future design of evidence-based protocols.

Mitomycin C: a clinical update

Mitomycin C was reviewed in this journal 25 years ago and an update of its clinical usefulness is appropriate. The current review is based on representative publications covering clinical trials performed throughout the world. Single agent activity in each of the major neoplastic diseases has been reassessed when possible and the most important combinations evaluated. It is concluded that mitomycin C has a definite place in the treatment of localized bladder cancer, is active, but needs to be redefined, in the context of newer regimens for breast, head and neck, and non-small cell lung cancers, is active in, but is being displaced by, other drugs in cervical, gastric and pancreatic cancers, and is probably no longer of therapeutic value in colon cancer. It is also recognized that as many newer treatments have clinical success, the therapeutic role of mitomycin C will require continuing re-investigation.
