Abstract We present a case of a 69-year-old man who had localized pleural metastasis without other organ metastases after nephrectomy for right renal cell carcinoma (RCC). He complained of respiratory symptoms for more than two years after the operation and was confirmed to have right pleural effusion and multiple pleural masses on computed tomography (CT). There were no abnormal findings in the other organs, but the pleural mass gradually increased in size on CT. We suspected malignant tumors s...

This is a first observational study of four patients on steroid pulse therapy for secondary organizing pneumonia with respiratory failure due to the Coronavirus Disease 2019 (COVID-19) in our hospital. All patients needed invasive mechanical ventilation and had bimodal worseness of their respiratory status with organizing pneumonia after intubation. All cases could successfully discontinue oxygen therapy without any severe adverse events after this pulse therapy. Although few previous reports sh...

Abstract Objectives Folate receptor alpha (FRα) is expressed on the cell surface, mediates its intracellular transport via receptor-mediated endocytosis, and is involved in cell division. Whether FRα could be a potential therapeutic target in FRα-expressing cancers remains unknown. Here, we retrospectively investigated the correlations between tumor FRα expression in lung adenocarcinoma (LADC) and clinicopathological features. Materials and methods FRα expression was evaluated using a tissue mic...

Although some prospective studies provided the evidence of corticosteroids for critically ill patients with COVID-19, the optimal dosage or timing of corticosteroids is still unknown. This is a case series of four patients on methyl-prednisolone pulses for the late phase of Coronavirus disease 2019 (COVID-19) with respiratory failure in our hospital. All patients needed invasive mechanical ventilation and had bimodal worseness of their respiratory status with consolidation and volume loss after ...

BACKGROUND: Cytotoxic chemotherapy for advanced non-small cell lung cancer (NSCLC) as second-line or subsequent treatment generally results in a poor treatment outcome. Several reports have indicated that subsequent cytotoxic chemotherapy in patients who have received immune checkpoint inhibitors (ICIs) might have relatively better efficacy. METHODS: The clinical data of advanced NSCLC patients treated with nivolumab during clinical practice at the National Cancer Center Hospital between 17 Dece...
