Radiotherapy plus chemotherapy with or without surgical resection for stage III non-small-cell lung cancer: a phase III randomised controlled trial Gefitinib or chemotherapy for non-small-cell lung cancer with mutated EGFR. Crizotinib versus chemotherapy in advanced ALK-positive lung cancer. Sequential vs. concurrent chemoradiation for stage III non-small cell lung cancer: randomized phase III trial RTOG 9410.
BACKGROUND Results from phase II studies in patients with stage IIIA non-small-cell lung cancer with ipsilateral mediastinal nodal metastases ( N2 ) have shown the feasibility of resection after concurrent chemotherapy and radiotherapy with promising rates of survival . We therefore did this phase III trial to compare concurrent chemotherapy and radiotherapy followed by resection with st and ard concurrent chemotherapy and definitive radiotherapy without resection . METHODS Patients with stage T1 - 3pN2M0 non-small-cell lung cancer were r and omly assigned in a 1:1 ratio to  concurrent induction chemotherapy  ( two cycles of cisplatin [ 50 mg/m(2 ) on days 1 , 8 , 29 , and 36 ] and etoposide [ 50 mg/m(2 ) on days 1 - 5 and 29 - 33 ] ) plus radiotherapy ( 45 Gy ) in multiple academic and community hospitals . If no progression , patients in group 1 underwent resection and those in group 2 continued radiotherapy uninterrupted up to 61 Gy . Two additional cycles of cisplatin and etoposide were given in both groups . The primary endpoint was overall survival ( OS ) . Analysis was by intention to treat . This study is registered with Clinical Trials.gov , number NCT00002550 . FINDINGS 202 patients ( median age 59 years , range 31 - 77 ) were assigned to group 1 and 194 ( 61 years , 32 - 78 ) to group 2 .  Median OS was 23.6 months ( IQR 9.0-not reached ) in group 1 versus 22.2 months ( 9.4 - 52.7 ) in group 2 ( hazard ratio [ HR ] 0.87 [ 0.70 - 1.10 ] ; p=0.24 ) . Number of patients alive at 5 years was 37 ( point estimate 27 % ) in group 1 and 24 ( point estimate 20 % ) in group 2 ( odds ratio 0.63 [ 0.36 - 1.10 ] ; p=0.10 ) . With N0 status at thoracotomy , the median OS was 34.4 months ( IQR 15.7-not reached ; 19 [ point estimate 41 % ] patients alive at 5 years ) . Progression-free survival ( PFS ) was better in group 1 than in group 2 , median 12.8 months ( 5.3 - 42.2 ) vs 10.5 months ( 4.8 - 20.6 ) , HR 0.77 [ 0.62 - 0.96 ] ; p=0.017 ) ; the number of patients without disease progression at 5 years was 32 ( point estimate 22 % ) versus 13 ( point estimate 11 % ) , respectively . Neutropenia and oesophagitis were the main grade 3 or 4 toxicities associated with chemotherapy plus radiotherapy in group 1 ( 77 [ 38 % ] and 20 [ 10 % ] , respectively ) and group 2 ( 80 [ 41 % ] and 44 [ 23 % ] , respectively ) . In group 1 , 16 ( 8 % ) deaths were treatment related versus four ( 2 % ) in group 2 . In an exploratory analysis , OS was improved for patients who underwent lobectomy , but not pneumonectomy , versus chemotherapy plus radiotherapy . INTERPRETATION Chemotherapy plus radiotherapy with or without resection ( preferably lobectomy ) are options for patients with stage IIIA(N2 ) non-small-cell lung cancer . FUNDING National Cancer Institute , Canadian Cancer Society , and National Cancer Institute of Canada BACKGROUND Non-small-cell lung cancer with sensitive mutations of the epidermal growth factor receptor ( EGFR ) is highly responsive to EGFR tyrosine kinase inhibitors such as gefitinib , but little is known about how its efficacy and safety profile compares with that of st and ard chemotherapy . METHODS We r and omly assigned 230 patients with metastatic , non-small-cell lung cancer and EGFR mutations who had not previously received chemotherapy to receive gefitinib or carboplatin-paclitaxel .  The primary end point was progression-free survival ; secondary end points included overall survival , response rate , and toxic effects . RESULTS In the planned interim analysis of data for the first 200 patients , progression-free survival was significantly longer in the gefitinib group than in the st and ard-chemotherapy group ( hazard ratio for death or disease progression with gefitinib , 0.36 ; P<0.001 ) , result ing in early termination of the study . The gefitinib group had a significantly longer median progression-free survival ( 10.8 months , vs. 5.4 months in the chemotherapy group ; hazard ratio , 0.30 ; 95 % confidence interval , 0.22 to 0.41 ; P<0.001 ) , as well as a higher response rate ( 73.7 % vs. 30.7 % , P<0.001 ) . The median overall survival was 30.5 months in the gefitinib group and 23.6 months in the chemotherapy group ( P=0.31 ) . The most common adverse events in the gefitinib group were rash ( 71.1 % ) and elevated aminotransferase levels ( 55.3 % ) , and in the chemotherapy group , neutropenia ( 77.0 % ) , anemia ( 64.6 % ) , appetite loss ( 56.6 % ) , and sensory neuropathy ( 54.9 % ) . One patient receiving gefitinib  died from interstitial lung disease . CONCLUSIONS First-line gefitinib for patients with advanced non-small-cell lung cancer who were selected on the basis of EGFR mutations improved progression-free survival , with acceptable toxicity , as compared with st and ard chemotherapy . ( UMIN-CTR number , C000000376 . BACKGROUND In single-group studies , chromosomal rearrangements of the anaplastic lymphoma kinase gene ( ALK ) have been associated with marked clinical responses to crizotinib , an oral tyrosine kinase inhibitor targeting ALK . Whether crizotinib is superior to st and ard chemotherapy with respect to efficacy is unknown . METHODS We conducted a phase 3 , open-label trial comparing crizotinib with chemotherapy in 347 patients with locally advanced or metastatic ALK-positive lung cancer who had received one prior platinum-based regimen . Patients were r and omly assigned to receive oral treatment with crizotinib ( 250 mg ) twice daily or intravenous chemotherapy with either pemetrexed ( 500 mg per square meter of body-surface area ) or docetaxel ( 75 mg per square meter ) every 3 weeks . Patients in the chemotherapy group who had disease progression were permitted to cross over to crizotinib as part of a separate study . The primary end point was progression-free survival . RESULTS The median progression-free survival was 7.7 months in the crizotinib group and 3.0 months in the chemotherapy group ( hazard ratio for progression or death with crizotinib , 0.49 ; 95 % confidence interval [ CI ] , 0.37 to 0.64 ; P<0.001 ) . The response rates were 65 % ( 95 % CI , 58 to 72 ) with crizotinib , as compared with 20 % ( 95 % CI , 14 to 26 ) with chemotherapy ( P<0.001 ) . An interim analysis of overall survival showed no significant improvement with crizotinib as compared with chemotherapy ( hazard ratio for death in the crizotinib group , 1.02 ; 95 % CI , 0.68 to 1.54 ; P=0.54 ) . Common adverse events associated with crizotinib were visual disorder , gastrointestinal side effects , and elevated liver aminotransferase levels , whereas common adverse events with chemotherapy were fatigue , alopecia , and dyspnea . Patients reported greater reductions in symptoms of lung cancer and greater improvement in global quality of life with crizotinib than with chemotherapy . CONCLUSIONS Crizotinib is superior to st and ard chemotherapy in patients with previously treated , advanced non-small-cell lung cancer with ALK rearrangement . ( Funded by Pfizer ; Clinical Trials.gov number , NCT00932893 . ) BACKGROUND The combination of chemotherapy with thoracic radiotherapy ( TRT ) compared with TRT alone has been shown to confer a survival advantage for good performance status patients with stage III non-small cell lung cancer . However , it is not known whether sequential or concurrent delivery of these therapies is the optimal combination strategy . METHODS A total of 610 patients were r and omly assigned to two concurrent regimens and one sequential chemotherapy and TRT regimen in a three-arm phase III trial . The sequential arm included cisplatin at 100 mg/m2 on days 1 and 29 and vinblastine at 5 mg/m2 per week for 5 weeks with 63 Gy TRT delivered as once-daily fractions beginning on day 50 . Arm 2 used the same chemotherapy regimen as arm 1 with 63 Gy TRT delivered as once-daily fractions beginning on day 1 [ corrected ] . Arm 3 used cisplatin at 50 mg/m2 on days 1 , 8 , 29 , and 36 with oral etoposide at 50 mg twice daily for 10 weeks on days 1 , 2 , 5 , and 6 with 69.6 Gy delivered as 1.2 Gy twice-daily fractions beginning on day 1 . The primary endpoint was overall survival , and secondary endpoints included tumor response and time to tumor progression . Kaplan-Meier analyses were used to assess survival , and toxic effects were examined using the Wilcoxon rank sum test . All statistical tests were two-sided . RESULTS Median survival times were 14.6 , 17.0 , and 15.6 months for arms 1 - 3 , respectively . Five-year survival was statistically significantly higher for patients treated with the concurrent regimen with once-daily TRT compared with the sequential treatment ( 5-year survival : sequential , arm 1 , 10 % [ 20 patients ] , 95 % confidence interval [ CI ] = 7 % to 15 % ; concurrent , arm 2 , 16 % [ 31 patients ] , 95 % CI = 11 % to 22 % , P = .046 ; concurrent , arm 3 , 13 % [ 22 patients ] , 95 % CI = 9 % to 18 % ) . With a median follow-up time of 11 years , the rates of acute grade 3 - 5 nonhematologic toxic effects were higher with concurrent than sequential therapy , but late toxic effects were similar . CONCLUSION Concurrent delivery of cisplatin-based chemotherapy with TRT confers a long-term survival benefit compared with the sequential delivery of these therapies
