    Pathological features of residual head and neck cancer after near-infrared photoimmunotherapy: implications of an unfavorable tumor immune microenvironment. (PubMed, Photodiagnosis Photodyn Ther)
    Residual tumors after near-infrared photoimmunotherapy can occur despite adequate laser irradiation and epidermal growth factor receptor expression. Our observations imply that insufficient immune activation within the tumor microenvironment may contribute to treatment resistance. Further characterization of the post-photoimmunotherapy tumor microenvironment will be essential to better understand treatment mechanisms and to optimize therapeutic efficacy.

    Severe drug-induced interstitial lung disease after photoimmunotherapy with cetuximab-sarotalocan sodium in a patient with oropharyngeal cancer: A case report. (PubMed, Respir Med Case Rep)
    He received two cycles of intravenous methylprednisolone (1 g/day, 3 days/cycle) followed by oral prednisolone at 1 mg/kg/day, which was gradually tapered. Because cetuximab is a component of CS, CS-PIT has the potential to induce DIILD. Risk assessments and monitoring for DIILD are recommended for patients receiving CS-PIT.

    Near-infrared photoimmunotherapy for recurrent cancer at the base of the tongue. (PubMed, Photodiagnosis Photodyn Ther)
    In NIR-PIT, administration of cetuximab sarotalocan sodium is followed by laser irradiation of the affected area, which theoretically should induce tumor cell death. EGFR expression was positive in all cases and expression score showed no significant change between before and after treatment. These findings suggest that puncture interval plays a critical role in therapeutic outcomes, whereas EGFR expression may not directly influence treatment efficacy.
