Older patients with EGFR mutation-positive non-small cell lung cancer treated with afatinib in clinical practice: A subset analysis of the non-interventional GIDEON study
Published date:

Excerpt:
In the 152 patients enrolled in GIDEON (69.7% female, 64.5%/22.4%/13.2% with Del19/L858R/other exon 18-21 mutations...twelve-month PFS rate was 58.9% and 43.9%, median PFS was 17.2 months and 10.6 months, ORR was 72.0% and 76.5%, twelve-month OS rate was 79.1% and 79.2%, 24-month OS rate was 52.0% and 61.7%, and median OS was 30.4 months and 27.4 months, respectively....Patients with EGFRm + NSCLC aged ≥70 years showed clinical benefit from first-line afatinib with no unexpected safety signals, supporting the use of afatinib in this setting.

Title:
Real-life comparison of afatinib and erlotinib in non-small cell lung cancer with rare EGFR exon 18 and exon 20 mutations: a Turkish Oncology Group (TOG) study
Published date:
04/05/2022
Excerpt:
We retrospectively evaluated survival characteristics of 125 patients with EGFR exon 18 and exon 20 mutated NSCLC who received erlotinib or afatinib as first line treatment between 2012 and 2021 from 34 oncology centres….PFS of exon 18 mutated arm was 7.0 months, exon 20 mutated arm was 4.3 months, and complex mutation positive group was 17.3 months, and this was statistically significant (p = 0.036).

Title:
Real Life Comparison of Afatinib and Erlotinib in Non-small Cell Lung Cancer With Rare EGFR Exon 18 and Exon 20 Mutations: a Turkish Oncology Group (TOG) Study.
Published date:
12/10/2021
Excerpt:
We retrospectively evaluated survival characteristics of 125 patients with EGFR exon 18 and exon 20 mutated NSCLC who received erlotinib or afatinib….OS of all patients was 21.4 months (95%CI: 16.1-26.6), while PFS was 7.2 months (95%CI: 5.1-9.3). When PFS and OS were compared according to the type of TKI used, PFS was 8.0 months (95%CI: 4.7-11.3) in the erlotinib arm and 7.0 months (95%CI: 4.4-9.6) in the afatinib arm.

EGFR Exon 18 Mutations in Advanced Non-Small Cell Lung Cancer: A Real-World Study on Diverse Treatment Patterns and Clinical Outcomes
Published date:

Excerpt:
There was a significant difference in median progression-free survival (mPFS) by therapeutic strategy (P = 0.017). The mPFS of 1G TKI, 2G TKI afatinib, chemotherapy, and 1G TKI in combination with chemotherapy were 7.7 (95% CI, 4.2-11.2), 11.3 (95% CI, 5.6-17.0), 5.0 (95% CI, 2.3-17.7), and 11.1 (95% CI, 5.9-16.4) months, respectively....Like afatinib, 1G TKI in combination with chemotherapy might be an effective treatment option for patients harboring EGFR exon 18 mutations.
