Tumor Lysis Syndrome in a Patient with BRAFV600E Mutated Colon Cancer Treated with Cetuximab and Encorafenib.
Tumor lysis syndrome (TLS) is a fatal complication associated with chemotherapy. We herein report a case of TLS in a 73-year-old woman with metastatic BRAFV600E mutated colon cancer after she received combined treatment with cetuximab and encorafenib. ⋯ Diuresis and rasburicase were initiated for TLS, and the laboratory data all normalized on day 8. Thus, the possibility of TLS being induced by targeted drugs in patients with solid tumors, including colorectal cancer, must not be overlooked.

Objective Pembrolizumab plus platinum and pemetrexed (Pemb-Plt-PEM) combination therapy is an effective first-line treatment for advanced non-squamous non-small-cell lung cancer (NSCLC), regardless of programmed death-ligand 1 expression. However, the effectiveness and feasibility of first-line Pemb-Plt-PEM therapy in elderly patients (≥75 years old) remain unclear. Therefore, this study investigated the safety and efficacy of first-line Pemb-Plt-PEM in elderly patients with non-squamous NSCLC. ⋯ Furthermore, the sex and NLR influenced the association between Pemb-Plt-PEM and the OS. The OS for low and high NLR values was 32.8 and 2.6 months, respectively. Conclusion First-line Pemb-Plt-PEM therapy is effective and feasible in elderly patients with non-squamous NSCLC.
