Essential drugs for cancer chemotherapy: memorandum from a WHO meeting

Essential drugs for cancer chemotherapy were reviewed in a consultation convened by WHO in Geneva. General principles regarding the proper role of cancer chemotherapeutic agents in relation to other established treatment modalities and the classification of tumours with respect to curative potential are discussed. Curable cancers and those cancers where the cost-benefit ratio clearly favours drug treatment can be managed appropriately using only 14 drugs.
