New approaches to cancer treatment

New approaches to cancer treatment include methods that improve the ability of the patient to tolerate the administration of aggressive chemotherapy. The use of bone marrow transplantation, hematopoietic growth factors, biologic response modifiers and toxicity-specific protective agents have potential for improving the response rates of several cancers and of improving patient survival. Further study of these treatment strategies, coupled with advances related to the clinical application of mechanisms for reversing chemotherapy drug resistance have important relevance for the future.
