ABSTRACT
An 86-year-old woman with leg edema and dyspnea on exertion was admitted to our hospital. Chest computed tomography (CT) revealed a mass in the anterior mediastinum with pericardial invasion. Histological examination with endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) led to the diagnosis of Masaoka stage IVa type B2 thymoma. For palliation, radiotherapy (32 Gy/16 fractions) and prednisolone (30 mg/day) were administered and tapered. After treatment, both the pericardial effusion and tumour size decreased. Combination therapy with steroids and radiotherapy may be effective for treating thymomas.
ABSTRACT
A woman in her mid-50s was admitted to our hospital with airway stenosis secondary to mediastinal lymph node enlargement. An AERO stent was placed under rigid bronchoscopy. Immediately after stent placement, tissue sampling was performed on the lymph nodes. Metastatic lesions were found to have an EGFR mutation (exon 19 deletion). Consequently, osimertinib treatment was initiated 15 days after stent placement. The tumour partially responded to osimertinib, and the airway stenosis improved. The patient underwent stent removal 66 days after stent placement. Our findings indicate that temporary oncological emergencies due to airway stenosis may be bridged by airway stenting.
ABSTRACT
BACKGROUND: Airway stenting is an established procedure for treating oncological emergencies in patients with airway disorders. In patients with airway hemorrhage, respiratory conditions may worsen during stenting. Bronchial artery embolization (BAE) is useful to prevent bleeding from the bronchus. We aimed to evaluate the efficacy and safety of airway stenting after BAE in patients with malignant airway disorders. METHODS: The medical records of all patients who underwent airway stenting following BAE at the National Hospital Organization Okayama Medical Center between 2016 and 2023 were retrospectively reviewed. RESULTS: Thirteen procedures (11 silicone Y stents, one hybrid stent, and one self-expandable metallic stent) were performed. The median duration from BAE to airway stenting was one day (range: 1-5 days). Nine patients experienced tumor shrinkage, and none experienced severe bleeding after BAE during the stent procedure. No other major complications were associated with the stent placement. The median survival time after stenting was 169 days (range; 24-1086). No serious complications caused by BAE, such as spinal cord infarction, were observed. CONCLUSIONS: Airway stent placement was safely performed after BAE without severe bleeding or acute respiratory failure. BAE, followed by airway stenting, is useful.

A 75-year-old woman with stage IVB (cT2bN3M1b) lung adenocarcinoma was administered nivolumab, ipilimumab, carboplatin, and paclitaxel. Fourteen days after receiving chemotherapy, she experienced an impaired consciousness and a cerebrospinal fluid analysis revealed high protein levels and pleocytosis. She was diagnosed with nivolumab- and ipilimumab-induced encephalitis and was treated with corticosteroids which were tapered to 10 mg/day, with no symptom recurrence. She died 18 weeks after the initial presentation, as the cancer worsened. An autopsy showed encephalitis and CD8+ lymphocyte infiltration around the blood vessels. Thus, immune-related adverse events should be suspected and treatment should be initiated for patients presenting with an impaired consciousness when concurrently being treated with nivolumab and ipilimumab.
ABSTRACT
In patients presenting with abnormal pulmonary nodules, especially those with a history of asthma, allergic bronchopulmonary mycosis should be considered. Eosinophil counts and IgE levels should be checked in such patients.
ABSTRACT
A 70-year-old woman with anti-aminoacyl-tRNA synthetase (ARS) antibody-positive interstitial lung disease (ARS-ILD) received daily medications and regular cyclophosphamide cycles for recurring exacerbations. Approximately four years after immunosuppression initiation, the patient was admitted for progressive dyspnea on exertion. Chest computed tomography (CT) findings were suggestive of acute exacerbation. Despite intensified immunosuppressive treatment, the radiographic findings worsened, and serum Krebs von den Lungen-6 (KL-6) levels increased. A bronchoalveolar lavage fluid (BALF) examination revealed amorphous globules and alveolar macrophages with eosinophilic granules. Owing to negative anti-GM-CSF antibody tests, a diagnosis of secondary pulmonary alveolar proteinosis (PAP) was established.
ABSTRACT
A 75-year-old woman with stage IVB (cT3N3M1c) extensive disease small-cell lung cancer was treated with carboplatin, etoposide, and atezolizumab. Ten days after pegfilgrastim initiation, during the second chemotherapy cycle, she experienced back pain. Contrast-enhanced computed tomography revealed soft tissue thickening around the descending aorta and brachiocephalic artery. She was diagnosed with atezolizumab and pegfilgrastim-induced large-vessel vasculitis (LVV) and was treated with prednisolone, which was tapered and discontinued after 14 weeks, with no symptom recurrence. LVV should be included in the differential diagnosis of patients with nonspecific body pain when pegfilgrastim and immune checkpoint inhibitors are used in combination.
ABSTRACT
Objective Airway stenting is an established procedure for treating various airway disorders. The AERO stent (Merit Medical Systems, South Jordan, USA) is a fully covered self-expandable metallic stent approved for use in Japan in 2014. However, its effectiveness in treating malignant airway disorders in patients with a poor performance status remains unclear. Therefore, we investigated the safety and efficacy of the AERO stent in patients with malignant airway disorders and a poor performance status. Methods We retrospectively reviewed the medical records of all patients who underwent AERO stent placement at our institute between April 2016 and March 2022, and 21 patients underwent 25 procedures for malignant airway disorders. All AERO stenting procedures were performed using an over-the-wire delivery system with flexible and/or rigid bronchoscopy. Results Eighteen of the 21 patients (85.7%) had a poor general condition (Eastern Cooperative Oncology Group performance status 3 or 4). AERO stents were successfully placed in 23 of the 25 procedures and migrated in the remaining 2 cases. Complications occurred in 10 cases, with infection being the most common (3 cases). Fourteen patients (66.6%) showed an improvement in their performance status. In addition, 5 of the 6 intubated patients were extubated following AERO stenting, and 11 patients subsequently received anticancer treatment. Conclusion The placement of the AERO stent is useful in patients with a poor performance status, including those who are intubated and afflicted with malignant airway disorders.
