From: Pneumatosis intestinalis associated with lenvatinib during thyroid cancer treatment: a case report
Clinical course. The graph shows the transition of thyroglobulin, the timing of lenvatinib treatment, and the dose. The times of external beam radiotherapy (EBRT), surgery, and radioactive iodine (RAI) are shown above the graph. The red arrow indicates the time of pneumatosis intestinalis (PI). The thyroglobulin level was decreased after introduction of lenvatinib, reflecting the anti-tumor effect of lenvatinib. PI occurred 14 weeks after the introduction, and it was improved by 1-week withdrawal of lenvatinib
