Photoimmunotherapy efficacy can be more accurately evaluated in an orthotopic mouse model than in a subcutaneous one. A pleural dissemination model is useful for assessing treatment methods for thoracic diseases, and near-infrared photoimmunotherapy (NIR-PIT) is a promising cancer treatment strategy combining tumor-targeting antibodies with photoabsorber-induced toxicity.
The efficacy of photoimmunotherapy can be evaluated more accurately with an orthotopic mouse model than with a subcutaneous one. A pleural dissemination model can be used for the evaluation of treatment methods for intrathoracic diseases such as lung cancer or malignant pleural mesothelioma. Near-infrared photoimmunotherapy (NIR-PIT) is a recently developed cancer treatment strategy that combines the specificity of tumor-targeting antibodies with toxicity caused by a photoabsorber (IR700Dye) after exposure to NIR light. The efficacy of NIR-PIT has been reported using various antibodies; however, only a few reports have shown the therapeutic effect of this strategy in an orthotopic model. In the present study, we demonstrate an example of efficacy evaluation of the pleural disseminated lung cancer model, which was treated using NIR-PIT.
