RESUMO
Aim: We investigated the effectiveness of durvalumab post-concurrent CRT (cCRT) and post-sequential CRT (sCRT) versus cCRT and sCRT alone and compared these outcomes with the PACIFIC trial. Methods: Four cohorts of stage III NSCLC patients who received CRT were included: cCRT with and without durvalumab, sCRT with and without durvalumab. PFS and OS were analyzed using Cox regression. Results: Durvalumab improved PFS (cCRT: aHR = 0.69, sCRT: aHR = 0.71) and OS (cCRT: aHR = 0.71, sCRT: aHR = 0.32), although not all results were significant. PFS was longer in the real-world than in the trial, while OS did not differ. Conclusion: Durvalumab after CRT improved the survival outcomes. The difference between PFS in our study and the trial may be due to differences in follow-up methods.
We assessed a medicine called durvalumab on patients with non-small cell lung cancer who received chemoradiotherapy in a real-world setting. We compared their outcomes with those from a clinical trial. Patients who received two types of chemoradiotherapy with or without durvalumab were included, and their progression-free survival (PFS) and overall survival (OS) outcomes were analyzed. We found that patients treated with durvalumab had better PFS and OS than those treated without durvalumab. PFS was longer in the real-world than in the clinical trial, but OS was similar. The difference in PFS may be due to differences in measuring PFS.

BACKGROUND: Development of the gut-brain axis in early life may be disturbed by antibiotic use. It has been hypothesized that this disturbance may contribute to development of neurodevelopmental disorders, including autism spectrum disorder and attention-deficit hyperactivity disorder. We aimed to assess the association between antibiotic use in early life and the risk of developing attention-deficit hyperactivity disorder or autism spectrum disorder, while controlling for shared genetic and environmental factors in a discordant twin design. METHODS: We conducted a cohort study in twins (7-12 years; 25 781 twins) from the Netherlands Twin Register (NTR) and a replication study in the Childhood and Adolescent Twin Study in Sweden (CATSS; 7946 9-year-old twins). Antibiotic use was recorded before age 2 years. Attention-deficit hyperactivity disorder and autism spectrum disorder were parent-reported in the Netherlands Twin Register and register-based in the Childhood and Adolescent Twin Study in Sweden. RESULTS: Early-life antibiotic use was associated with increased risk of attention-deficit hyperactivity disorder development [pooled odds ratio (OR) 1.10, 95% confidence interval (CI) 1.02-1.17] and autism spectrum disorder (pooled OR 1.15, 95% CI 1.06-1.25) in a case-control design. When restricting to monozygotic twin pairs discordant for the outcome, associations disappeared for both disorders in both cohorts (attention-deficit hyperactivity disorder OR 0.90, 95% CI 0.48-1.69 and OR 0.80, 95% CI 0.37-1.76, and autism spectrum disorder OR 0.66, 95% CI 0.38-1.16 and OR 0.29, 95% CI 0.02-4.50, respectively). CONCLUSIONS: Our findings suggest that the association between early-life antibiotic use and risk of attention-deficit hyperactivity and autism spectrum disorder may be confounded by shared familial environment and genetics.
