Among subjects at high risk for lung cancer who were screened in three rounds of CT scanning and in whom noncalcified pulmonary nodules were evaluated according to volume and volume-doubling time, the chances of finding lung cancer 1 and 2 years after a negative first-round test were 1 in 1000 and 3 in 1000, respectively.

v1.1). Secondary efficacy endpoints included BIRC-assessed objective response rate (ORR), intracranial ORR (iORR), and intracranial PFS (iPFS). Interim analyses were planned at 50% and 75% of planned PFS events (n¼198). Result: 275 patients were randomized (brigatinib/crizotinib, n¼137/138); median age (years) 58/ 60. 26%/27% received prior chemotherapy for advanced disease, and 29%/30% had baseline brain metastases. At data cutoff (19 February 2018), median follow-up brigatinib/crizotinib: 11.0/9.25 months; with 99 PFS events, brigatinib met the prespecified threshold for statistical superiority vs crizotinib in the primary endpoint, BIRC-assessed PFS (HR 0.49, 95% CI 0.33e0.74, log-rank P¼0.0007); brigatinib mPFS was not reached (95% CI NReNR) vs crizotinib 9.8 months (95% CI 9.0e12.9). Investigator-assessed PFS HR 0.45 (95% CI 0.30e0.68), logrank P¼0.0001. Table shows additional efficacy data. Most common treatment-emergent AEs grade 3: brigatinib: increased CPK (16.2%), increased lipase (13.2%), hypertension (9.6%); crizotinib: increased ALT (9.5%), AST (5.8%), and lipase (5.1%). Any grade ILD/pneumonitis: brigatinib, 3.7%; crizotinib, 2.2%. Discontinuations due to AE (brigatinib/crizotinib): 11.8%/8.8%. Conclusion: Brigatinib showed a statistically and clinically significant improvement in PFS compared with crizotinib in ALK inhibitorenaive ALK+ NSCLC.

Lung cancer screening (LCS) with low-dose computed tomography (LDCT) was demonstrated in the National Lung Screening Trial (NLST) to reduce mortality from the disease. European mortality data has recently become available from the Nelson randomised controlled trial, which confirmed lung cancer mortality reductions by 26% in men and 39–61% in women. Recent studies in Europe and the USA also showed positive results in screening workers exposed to asbestos. All European experts attending the “Initiative for European Lung Screening (IELS)”—a large international group of physicians and other experts concerned with lung cancer—agreed that LDCT-LCS should be implemented in Europe. However, the economic impact of LDCT-LCS and guidelines for its effective and safe implementation still need to be formulated. To this purpose, the IELS was asked to prepare recommendations to implement LCS and examine outstanding issues. A subgroup carried out a comprehensive literature review on LDCT-LCS and presented findings at a meeting held in Milan in November 2018. The present recommendations reflect that consensus was reached.
