Abstract: | The rapid appearance of many new chemical substances which possess some antineoplastic effects has created a complex problem for the practicing physician. These agents which have shown promise in man and lower animals are grouped according to their modes of action. Each substance is discussed thoroughly with regard to its structure, activity, and influence upon the neoplasms of man. Key references are cited, and the practical value of each chemical agent is defined. The proper methods of administration of the compounds recommended for use are carefully described. In addition a section on agents whose therapeutic value has been disproven is also included. |
