Osimertinib plus anlotinib in untreated, EGFR-mutated, advanced non-small-cell lung cancer with concurrent alterations: a multicenter phase II study.
Trial report in The oncologist, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThe standard first-line treatment for advanced EGFR-mutated non-small cell lung cancer (NSCLC) is EGFR tyrosine kinase inhibitors. However, concurrent mutations facilitate resistance evolution in EGFR-mutant lung adenocarcinoma and combination therapies may offer a superior approach. This study explores the efficacy and safety of osimertinib plus anlotinib as first-line treatment for advanced NSCLC with EGFR co-mutations. MATERIALS AND
methodsThis study prospectively enrolled patients with advanced NSCLC harboring EGFR (19Del/21L858R) mutations and ≥1 mutation in TP53, PIK3CA, or RB1, who had not undergone systemic treatment. Kaplan-Meier survival analysis tested the differences among patients with different concurrent mutations. ctDNA test was administered before and after treatment and its correlation with efficacy.
resultsA total of 38 patients were enrolled, with co-mutations in TP53 (76.3%), PIK3CA (26.3%), and RB1 (2.6%). With a median follow-up of 25.6 months, the median progression-free survival (PFS) was 29.0 months (95% CI, 18.6-NR), and 1-year PFS rate was 85% (95% CI, 70.4%-94.5%). Objective response rate was 73.7% (95% CI, 56.9%-86.3%), and disease control rate was 100.0% (95% CI, 90.7%-100.0%). Adverse events of any grade occurred in all patients. Seven (18.4%) patients experienced grade 3 treatment-related adverse events (TRAEs), with no grade 4 TRAEs or treatment-related deaths.
conclusionOsimertinib plus anlotinib shows promising efficacy and manageable toxicity as first-line treatment for advanced NSCLC with EGFR co-mutations (ChiCTR2300070023). CLINICAL
trial registrationThis study was registered in the Chinese Clinical Trial Registry (ChiCTR) under the registration number ChiCTR2300070023 on March 31, 2023 (https://www.chictr.org.cn).
