Our study aimed to uncover the expression of long non-coding RNA LOC105376794 between 19del and 21L858R mutation, and explore the mechanism that regulates cells' biological behavior and gefitinib sensitivity in lung adenocarcinoma cells with 19del. Transcriptome sequencing was conducted to identify differentially expressed lncRNAs between EGFR 19del and 21L858R mutation in serum through the DNBSEQ Platform. Protein-protein interaction network and Kyoto Encyclopedia of Genes and Genomes pathway were conducted to analyze the relationship between lncRNAs and mRNAs through STRING and Dr. TOM. Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) was used to measure the expression of lncRNA LOC105376794 in serum and cells. Loss-of-function experiments were used to validate the biological function and gefitinib sensitivity of LOC105376794 in lung adenocarcinoma cells. Protein levels were detected by western blotting.

This research concentrates on assessing the efficacy and safety of anlotinib in combination with ICIs for the treatment of ES-SCLC. We undertook a retrospective analysis of patients with extensive-stage SCLC who received anlotinib in combination with ICIs as second-line and subsequent treatment at Zhejiang Cancer Hospital between April 2020 and April 2023. Survival rates were analyzed using the Kaplan-Meier method. Among the 43 patients who received combination therapy, there were no cases of complete response (CR), 16 patients who achieved partial response (PR), 21 patients who had stable disease (SD), and 6 patients who experienced disease progression (PD). This resulted in an overall response rate (ORR) of 37.2% (16/43) and a disease control rate (DCR) of 86.0% (34/43).
