Testing Procedures

Types and dosages of drugsAlkylating agents , antimetabolites, plant alkaloids , topoisomerase inhibitors , antibiotics, anti-tumor : the majority of chemotherapy agents can be divided . And all these drugs affect to some extent on the synthesis and division , or function of DNA .Some newer agents do not act directly on the DNA . This is the case for tyrosine kinase inhibitor new imatinib mesylate, and directly target the molecular abnormalities in certain types of cancer ( cancer of the blood , and colon cancer ) .Other drugs affect the behavior of cancer cells without attacking the cells directly . Including hormones for this type of adjuvant therapy .Dose of chemotherapy can be very difficult : too low a dose to the tumor to be ineffective , while in excessive toxicity would be unbearable for the patient. Therefore it has been established in many hospitals " testing procedures " to get proper treatment.In general , and a dose of " body surface " of the patient, is set approximately by calculating the size and weight. Recently , scientists have small pumps on the surface of cancer cells to expel chemotherapy within the cell that have been identified . This research is a P -glycoprotein and other such waste micropumps active. Inhibitors - P -glycoprotein function has been run since June 2007 , and increase the effectiveness of chemotherapy
