36. Operative risks after induction chemotherapy Siegenthaler et al., Ann Thor Surg 71:1105, 2001

37. Operative risks after induction chemotherapy MDACC (-ed) Stage specific analysis : no difference in morbidity of CS vs. S alone Multivariate analysis: only CAD and pneumonectomy were independent risk factors for a major postoperative event. Siegenthaler et al., Ann Thor Surg 71:1105, 2001

38. Operative risks after induction chemotherapy MSKCC Jan 1993 to Dec 1999 412 pulmonary resections after induction therapy ( ages ranged 25-82) Preop chemotherapy: carboplatin/ paclitaxel 32% MVP 38% Preop radiotherapy as well : 18% Martin J et al., Ann Thorac Surg 2001; 72: 1149-54

39. Operative risks after induction chemotherapy MSKCC (-ed) 297 lobectomies ( 9 sleeves, 26 bilobectomies ) 97 pneumonectomies ( 20%) 18 lesser resections, 58 O&C 22% were extended resections Martin J et al., Ann Thorac Surg 2001; 72: 1149-54

40. Operative risks after induction chemotherapy MSKCC (-ed) Operative mortality Overall 3.8% Lobectomy 2.4% Left Pneumonectomy 0% Right Pneumonectomy 23.9% • Multivariate analysis: right pneumonectomy was the only predictor of mortality Martin J et al., Ann Thorac Surg 2001; 72: 1149-54

41. Operative risks after induction chemotherapy MSKCC (conclusion) Major morbidity 26.6% , mainly respiratory Multivariate analysis: Increased operative blood loss, low FEV1 and right pneumonectomy were the only independent predictors of post-operative morbidity The type of induction regimen was not a risk factor. Martin J et al., Ann Thorac Surg 2001; 72: 1149-54

42. Operative risks after induction chemotherapy Does induction chemotherapy without radiationtherapy really increase the morbidity and mortality of lung resection ? Probably not… but most of the data published so far is either retrospective and/or comparing to historical controls ...

49. Will induction chemotherapy become the standard of care for our patients with early stage disease ?Only by completing the ongoing clinical trials in a timely fashion, will we be able to answer this very important question.
