Tezepelumab improved chronic eosinophilic pneumonia in severe asthma patients with liver cirrhosis

Systemic administration of corticosteroids is used in the treatment of chronic eosinophilic pneumonia (CEP). However, in patients with CEP as well as other comorbidities, the adverse effects of corticosteroids should be minimized as much as possible. A 71-year-old woman was presented with aggravating asthma with CEP and sinusitis, and she had uncompensated liver cirrhosis (LC) with a Child-Pugh score of 7. Initial treatment with a low dose of oral corticosteroids (OCSs) in combination with tezepelumab, an anti-thymic stromal lymphopoietin (TSLP) antibody, resulted in rapid improvement of asthma and CEP without deteriorating LC. Sinusitis also improved after ceasing OCS. This case suggested that tezepelumab may be useful as a treatment option for patients with CEP, especially those with liver dysfunction

Feasibility study of chemoradiotherapy followed by amrubicin and cisplatin for limited-disease small cell lung cancer

To evaluate the feasibility of amrubicin plus cisplatin (AP) following chemoradiotherapy for limited-disease small-cell lung cancer, chemo-naïve patients aged 20–70 years with a performance status of 0 or 1 and normal organ functions were treated with etoposide 100 mg/m2 on days 1–3, cisplatin 80 mg/m2 on day 1 and concurrent thoracic radiotherapy at 45 Gy/30 fractions (EP-TRT), followed by three cycles of amrubicin 40 mg/m2 on days 1–3 and cisplatin 60 mg/m2 on day 1 every 3 weeks. The EP-TRT could be completed in 21 patients (15 male and 6 female patients with a median age of 62 years). Of these, 2, 1 and 18 (86%) patients received one, two and three cycles of AP, respectively. Sixteen (76%) patients required granulocyte-colony stimulating factor (G-CSF) support. Grade 3/4 neutropenia occurred in all patients. Grade 3 febrile neutropenia was observed in 9 patients, lasting for 1 day in 5 patients. The incidences of grade 3/4 thrombocytopenia and anemia were 43 and 24%, respectively. Grade 3 infection and anorexia occurred in 2 and 3 patients, respectively. The response rate was 95%. The median (95% confidence interval [CI]) progression-free survival (PFS) was 41.9 (0–102) months, and the 5-year PFS rate (CI) was 41.9% (20.4–63.4%). The median overall survival (OS) has not been reached yet, and the 5-year OS rate (CI) was 57.8% (35.2–80.4%). In conclusion, EP-TRT followed by AP therapy was well-tolerated, although a large number of patients required G-CSF support

Risk factors associated with fatal pulmonary hemorrhage in locally advanced non-small cell lung cancer treated with chemoradiotherapy

<p>Abstract</p> <p>Background</p> <p>The purpose of this study was to identify the risk factors associated with fatal pulmonary hemorrhage (PH) in patients with locally advanced non-small cell lung cancer (NSCLC), treated with chemoradiotherapy.</p> <p>Methods</p> <p>The medical records of 583 patients with locally advanced NSCLC, who were treated with chemoradiotherapy between July 1992 and December 2009 were reviewed. Fatal PH was defined as PH leading to death within 24 h of its onset. Tumor cavitation size was defined by the cavitation diameter/tumor diameter ratio and was classified as minimum (< 0.25), minor (≥ 0.25, but < 0.5), and major (≥ 0.5).</p> <p>Results</p> <p>Of the 583 patients, 2.1% suffered a fatal PH. The numbers of patients with minimum, minor, and major cavitations were 13, 11, and 14, respectively. Among the 38 patients with tumor cavitation, all 3 patients who developed fatal PH had major cavitations. On multivariate analysis, the presence of baseline major cavitation (odds ratio, 17.878), and a squamous cell histology (odds ratio, 5.491) proved to be independent significant risk factors for fatal PH. Interestingly, all patients with fatal PH and baseline major cavitation were found to have tumors with squamous cell histology, and the occurrence of fatal PH in patients having both risk factors was 33.3%.</p> <p>Conclusions</p> <p>Patients at high risk of fatal PH could be identified using a combination of independent risk factors.</p

Cell-Based Therapy for Fibrosing Interstitial Lung Diseases, Current Status, and Potential Applications of iPSC-Derived Cells

Fibrosing interstitial lung diseases (FILDs), e.g., due to idiopathic pulmonary fibrosis (IPF), are chronic progressive diseases with a poor prognosis. The management of these diseases is challenging and focuses mainly on the suppression of progression with anti-fibrotic drugs. Therefore, novel FILD treatments are needed. In recent years, cell-based therapy with various stem cells has been investigated for FILD, and the use of mesenchymal stem cells (MSCs) has been widely reported and clinical studies are also ongoing. Induced pluripotent stem cells (iPSCs) have also been reported to have an anti-fibrotic effect in FILD; however, these have not been as well studied as MSCs in terms of the mechanisms and side effects. While MSCs show a potent anti-fibrotic effect, the possibility of quality differences between donors and a stable supply in the case of donor shortage or reduced proliferative capacity after cell passaging needs to be considered. The application of iPSC-derived cells has the potential to overcome these problems and may lead to consistent quality of the cell product and stable product supply. This review provides an overview of iPSCs and FILD, followed by the current status of cell-based therapy for FILD, and then discusses the possibilities and perspectives of FILD therapy with iPSC-derived cells

Trends in chemotherapy for elderly patients with advanced non-small-cell lung cancer.

BACKGROUND: In approximately the year 2000, the results of a number of important studies of non-small-cell lung cancer (NSCLC) were published. METHODS: Between July 1992 and December 2003, 223 patients with NSCLC aged > or = 70 years received chemotherapy alone as their initial treatment at the National Cancer Center Hospital East. These patients were divided into 2 groups: those that began treatment between 1992 and 1999 (group A) and between 2000 and 2003 (group B). The details of chemotherapy regimens and outcomes were compared. RESULTS: In group A, 83% of patients received platinum-based chemotherapy, two-thirds of these regimens comprised platinumplus second-generation combination chemotherapy. In contrast, although 55% of patients received platinum-based chemotherapy in group B, 41% of patients received non-platinum-based chemotherapy. Among patients in group B, performance status was significantly associated with the selection of platinum-based or non-platinum-based chemotherapy; age was marginally associated with this selection. Median survival time (MST), 1-year survival rate, and 2-year survival rate were 6.7 months, 14%, and 7%, respectively, in group A, and 8.1 months, 35%, and 20% in group B (p=0.0109). Multivariate analysis revealed that clinical stage and administration of salvage chemotherapy were independent prognostic factors. CONCLUSIONS: In and after the year 2000, chemotherapy regimens changed greatly and survival of elderly patients significantly improved in our institute, and this improvement appears to be attributable mostly to the effect of salvage chemotherapy. These results suggest that even elderly patients should be offered salvage chemotherapy regardless of age, if possible
