Tyrosine kinase inhibitors (TKIs) are widely used for systemic chemotherapy of hepatocellular carcinoma (HCC). Arterial thromboembolism (ATE) has been reported to be an adverse event associated with TKI therapy, but its incidence is rare. Here, we report a case of an HCC patient who developed a thrombus in the superior mesenteric artery (SMA) while on TKI therapy. The patient was a 78-year-old Japanese man with hepatitis C virus-associated HCC with multiple nodules. Several sessions of transarterial chemoembolization therapy caused him to become refractory to the treatment. Sorafenib and regorafenib therapy had also been previously performed, but his disease continued to progress gradually. Therefore, we started lenvatinib therapy. When a contrast-enhanced computed tomography (CT) examination was performed 2 months later, we found a thrombus in the SMA. Retrospective analysis of the CT images revealed that the thrombus formed during the sorafenib-regorafenib sequential therapy and it developed rapidly, especially during the lenvatinib therapy. An HCC patient developed a thrombus in the SMA during TKI therapy. The incidence of ATE is rare in TKI treatment; however, long-term or sequential TKI therapy may increase the frequency of ATE. Further study is needed.

Objective: To analyze the impact of tyrosine kinase inhibitor (TKI) maintenance therapy following allogeneic hematopoietic stem cell transplantation (HSCT) in patients with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph + ALL) on recurrence rates and prognosis for the 2 transcripts, p190 and p210.
Methods: We conducted a retrospective analysis of clinical data from 58 patients diagnosed with Ph + ALL who underwent HSCT. All patients received TKI maintenance therapy following hematopoietic reconstruction post-transplantation.

Uncommon epidermal growth factor receptor (EGFR) mutations in non-small cell lung cancer (NSCLC) pose therapeutic challenge due to limited response to EGFR tyrosine kinase inhibitors (TKIs). This study presents preclinical evidence and mechanistic insights into the combination of lazertinib, a third-generation EGFR-TKI; and amivantamab, an EGFR-MET bispecific antibody, for treating NSCLC with uncommon EGFR mutations. The lazertinib-amivantamab combination demonstrates significant antitumor activity in patient-derived models with uncommon EGFR mutations either before treatment or after progressing on EGFR-TKIs.

Introduction: Sarcomas are a rare and diverse group of mesenchymal-origin solid tumors, constituting only 1% of adult malignancies and classified into soft tissue and bone sarcomas. For localized disease, surgery and radiotherapy remain the cornerstone treatments. However, systemic options for advanced stages are limited, with an overall survival of approximately 20 months.

Small molecules targeting activating mutations within the epidermal growth factor receptor (EGFR) are efficacious anticancer agents, particularly in non-small cell lung cancer (NSCLC). Among these, lazertinib, a third-generation tyrosine kinase inhibitor (TKI), has recently gained FDA approval for use in combination with amivantamab, a dual EGFR/MET-targeting monoclonal antibody. This review delves into the discovery and development of lazertinib underscoring the improvements in medicinal chemistry properties, especially in comparison with osimertinib.

Introduction: Although tyrosine kinase inhibitors (TKIs) are effective against NSCLC harboring sensitizing gene mutations, acquired resistance is inevitable. Preclinical studies suggest that combining EGFR TKI and monoclonal antibody therapies may have activity in mutated NSCLC that has progressed on TKI therapy alone. Therefore, we prospectively evaluated afatinib plus necitumumab in patients with mutated NSCLC.
