Abstract
BACKGROUND

Lung cancer is increasing in incidence worldwide, and targeted therapies are developing at a rapid pace. Furthermore, the KRAS specific gene is strongly associated with non-small cell lung cancer (NSCLC). Adult patients with locally advanced or metastatic NSCLC who have tested positive for the KRAS G12C mutation and have progressed after at least one systemic treatment are treated with sotorasib.

CASE SUMMARY

In this study, we report on an advanced NSCLC with a KRAS G12C mutation. The histological diagnosis indicates stage IVB left lung adenocarcinoma with pelvic and bone metastases, identified as cT4N2bM1c. Using circulating tumor DNA analysis, it was possible to determine the mutation abundance of the KRAS gene exon 2, c.34G > Tp.G12C, which was 32.3%. The patient was advised to take sotorasib as part of their treatment. The imaging data were compared before and after treatment. Furthermore, clinical reassessments and regular serial blood testing were conducted. We found that the patient’s clinical symptoms significantly improved after receiving sotorasib medication, and there were no notable side effects, such as liver toxicity, during the treatment.

CONCLUSION

Sotorasib has shown promising clinical efficacy in patients with the KRAS G12c mutation and has no apparent toxic side effects.

Core Tip: In this study, we demonstrate the efficacy of sotorasib in treating advanced non-small cell lung cancer with the KRAS G12C mutation. A patient diagnosed with stage IVB adenocarcinoma, exhibiting pelvic and bone metastases, showed a significant improvement in clinical symptoms post-sotorasib treatment, with no severe side effects observed. This case highlights the potential of targeted therapies in personalized cancer treatment, emphasizing the importance of genomic profiling for therapeutic decision-making.
