Therapy ConceptsTherapy Concepts

• Phase Specific drugs – work only on a specific phase of cell growth– most effective in rapidly growing cells

• Phase Non-Specific drugs – work on more than one phase of cell growth– most effective in rapidly growing cells

• Phase Specific drugs – work only on a specific phase of cell growth– most effective in rapidly growing cells

• Phase Non-Specific drugs – work on more than one phase of cell growth– most effective in rapidly growing cells

Therapy ConceptsTherapy Concepts

• Chemotherapy Terminology

– Induction- drug therapy used as primary treatment (leukemia)

– Consolidation - drug therapy used as follow up after remission from induction (leukemia)

– Adjuvant- drug therapy after surgery or XRT

– Neo-adjuvant - drug therapy before surgery or XRT which is not adequate alone.

– Salvage - drug therapy when primary drug treatment after relapse.

Therapy ConceptsTherapy Concepts

• Chemotherapy Terminology (cont)

– Regional - drug therapy localized to a specific area (e.g. limb perfusion, intrathecal, intraperitoneal)

– Maintenance - drug therapy used to maintain stable disease or remission.

– High Dose - doses above the standard range used primarily in combo with bone marrow rescue. Assumption that dose-intensity is effective.

– Palliation - drug therapy given to reduce symptoms without an intent to cure disease.

• Response Criteria

– Complete Response - Complete disappearance of signs and symptoms for at least 1 month.

– Partial Response - >50% reduction of tumor mass of all measured lesions and no new lesions.

– Stable Disease - No significant change in tumor mass neither increasing or decreasing by 25%.

– Progressive Disease- More than 25% increase in tumor mass

• Response Criteria

– Complete Response - Complete disappearance of signs and symptoms for at least 1 month.

Therapy ConceptsTherapy Concepts

• Gompertzian Model of Tumor Growth

– Growth rate of tumor cells decreases with time

– Response to chemotherapy is during rapid growth phase.

Therapy ConceptsTherapy Concepts

• Goldie-Coldman Hypothesis

– A fraction of tumor cells will develop resistance after treatment.

– This clone will continue to grow even though the patient appears to respond.

– Alternating combinations of chemotherapy agents early in treatment is necessary to prevent development resistant clones.

Therapy ConceptsTherapy Concepts

• Worst-Drug Rule - Day

– Drug A works better than drug B against a tumor.

– Use Drug B first to shrink tumor.

– Use Drug A sequentially to overcome resistance.

– Assumes all tumors of resistant clones.

– Some tumors respond best to sequential therapy allowing for sparing of toxicity.
