23 The Christie NHS Foundation Trust Updated June 2010 How does Radiotherapy work? Ionising radiation damages cells The most sensitive cellular component is DNA DNA

24 The Christie NHS Foundation Trust Updated June 2010 Radiotherapy – Biological Aspects DNA damage manifests at cell division “Early cell kill” v. “late cell kill” Related to proliferative activity

25 The Christie NHS Foundation Trust Updated June 2010 Radiotherapy – Biological Aspects Early: - usually the cancer –Skin, GI tract, Bone marrow Late: –Kidney, CNS

26 The Christie NHS Foundation Trust Updated June 2010 If the Kidneys receive a toxic dose of radiotherapy how long after radiotherapy will the patient show maximum renal impairment? 1.10 days 2.4 weeks 3.3 months 4.12 months 5.24 months Q

28 The Christie NHS Foundation Trust Updated June 2010 How does Radiotherapy work? The most sensitive cellular component is DNA The malignant cell have impaired DNA repair mechanisms DNA DNA damage can be repaired

29 The Christie NHS Foundation Trust Updated June 2010 Radiotherapy – Biological Selectivity Normal tissue cancer Cell No.
