11 Pignon et al LACE Collaborative Group JCO 2008 analysis from the five largest trials 4,584 patients cisplatin-based chemotherapy in patients with completely resected NSCLC 5-year absolute benefit of 5.4% from chemotherapy.

12 Adjuvant chemotherapy Two trials FRE-IALT and ANITA significant OS benefits associated with postoperative chemotherapy in stage IIIA disease. For the subgroup of stage IIIA patients in ANITA (n = 325), the HR was 0.69 (95% CI, ), and the result for the FRE- IALT trial (n = 728) was HR = 0.79 (95% CI, ). Chemotherapy effect was higher in patients with a better performance status (PS). Douillard et al ANITA Lancet 2006 Arriagada et al N Engl. J M 2004

13 TREAT Adjuvant cis+pem vs cis+vinorelbine Ο συνδυασμός Cisplatin+ Pemetrexed στην επικουρική θεραπεία είναι καλύτερα ανεκτός λιγότερο τοξικός επιτρέπει χορήγηση μεγαλύτερης συνολικής δόσης και βέλτιστης έντασης δόσης (dose density) H δυσανεξία του συνδυασμού Cisplatin+ Vinorelbine οφείλεται κυρίως σε αιματολογική τοξικότητα Αποτελέσματα πολύ πρώϊμα για έλεγχο δραστικότητας (υψηλό ποσοστό squamous-45%)

19 Chemoradiation therapy A meta-analysis of patient data from 11 trials Lung Cancer Collaborative Group BMJ 1995 Cisplatin-based combinations plus radiation therapy resulted in a 10% reduction in the risk of death compared with radiation therapy alone. A meta-analysis of 13 trials 2,214 patients Rowell et al Cochrane Database 2004 The addition of concurrent chemotherapy to radical radiation therapy reduced the risk of death at 2 years A meta-analysis from 1,764 patients 9 trials Auperin et al Ann Oncol 2006 radiation therapy and chemotherapy compared with radiation therapy alone benefit of chemotherapy of 4% at 2 years. platinum with etoposide more effective than platinum alone.

20 Concurrent versus sequential chemoradiation therapy A meta-analysis of three trials evaluated concurrent versus sequential treatment (711 patients) The analysis indicated a significant benefit of concurrent over sequential treatment (RR = 0.86; 95% CI, ; P =.003). All studies used cisplatin-based regimens and once-daily radiation therapy More deaths (3% OS rate) were reported in the concurrent arm, not statistical significant There was more acute esophagitis (grade 3 or worse) with concurrent treatment compared with sequential treatment Rowell et al Cochrane Database 2004

26 Neoadjuvant therapy is recommended in selected patients Which patients should be operated on after induction chemo for N2 nsclc? analysis of 175 patients 7 year experience Those who respond to induction chemo In patients with stage IIIA-N2 disease and PS<2, induction chemoradiotherapy with cisplatin-etoposide followed by either surgical resection or thoracic radiotherapy are both valid options with comparable outcomes.

36 State of the art treatment of SCLC P-based combination chemotherapy (PE) at full standard doses, x 4-6 as 1st line treatment for both LD and ED patients. Early thoracic irradiation (TRT), Gy, added to CT for LD patients. Prophylactic cranial irradiation (PCI), Gy, for patients with either LD or ED and CR/good PR. Single agent CT (Topotecan) as 2nd line treatment for relapsed SCLC. Amrubicin? A Ardizzoni, ASCO 2007
