The present study reports a rare case of radiation recall pneumonitis attributed to ifosfamide that was used as a single antitumor agent for a recurrent malignant soft tissue tumor, arising from the chest wall. A 74-year-old man, who had a mass in his right upper chest wall, underwent surgical excision under the diagnosis of chronic expanding hematoma. He was referred to the present hospital with a recurrent tumor as the excised tumor was diagnosed as undifferentiated high-grade sarcoma. The extension of the tumor following previous surgery was aggressive and the tumor margins were unclear on magnetic resonance imaging...

Background: Growing data suggest that DNA damage repair and detoxification pathways play crucial roles in radiation-induced toxicities. To determine whether common functional single-nucleotide polymorphisms (SNPs) in candidate genes from these pathways can be used as predictors of radiation pneumonitis (RP), we conducted a prospective study to evaluate the associations between functional SNPs and risk of RP. Methods: We recruited a total of 149 lung cancer patients who had received intensity modulated radiation therapy (IMRT)...

Bacterial pathogenesis depends on changes in metabolic and virulence gene expression in response to changes within a pathogen's environment. The plague-causing pathogen, Yersinia pestis, requires expression of the gene encoding the Pla protease for progression of pneumonic plague. The catabolite repressor protein Crp, a global transcriptional regulator, may serve as the activator of pla in response to changes within the lungs as disease progresses. By using gene reporter fusions, the spatial and temporal activation of the crp and pla promoters was measured in a mouse model of pneumonic plague...

BACKGROUND: Studies of a modified XELIRI (mXELIRI; capecitabine plus irinotecan) regimen suggest promising efficacy and tolerability profiles in the first-line and second-line settings. Therefore, we aimed to compare the efficacy and safety of the mXELIRI regimen with that of standard FOLFIRI (leucovorin, fluorouracil, and irinotecan), with or without bevacizumab in both regimens, as a second-line therapy for metastatic colorectal cancer. METHODS: We did a multicentre, open-label, randomised, non-inferiority, phase 3 trial...

PURPOSE: To evaluate in an observational way the clinical impact of a hypofractionated irradiation schedule in patients with unresectable non-small cell lung cancer (NSCLC). METHODS: Forty elderly patients (24 men/16 women) diagnosed with unresectable stage IIIb/IV NSCLC unfit for chemotherapy, were treated with once-a-week hypofractionation schedule. All patients had a poor performance status. A dose of 255 Gy in 3 weekly fractions was prescribed while a 3D conformal technique (3D-CRT) was used for irradiation...

The development of immune system modulating agents, such as immune checkpoint inhibitors (ICIs), has revolutionized cancer treatment. Nivolumab, a human monoclonal antibody against PD-1, has emerged as an efficient treatment for various malignancies, including non-small cell lung cancer (NSCLC); however, it is associated with important immune related side-effects, attributed to organ-specific inflammation, such as immune-mediated pneumonitis, a relatively uncommon, albeit potentially fatal adverse event. We herein present the unique case of severe interstitial pneumonitis with concomitant detection of Human Herpes Virus 6 (HHV-6) in a nivolumab treated patient with NSCLC...

PURPOSE: Clinician ratings of concurrent chemoradiation (CRT)-induced radiation pneumonitis (RP) in patients with non-small cell lung cancer (NSCLC) are based on both imaging and patient-reported lung symptoms. We compared the value of patient-reported outcomes versus normal-lung uptake of18 F-fluoro-2-deoxyglucose in positron emission computed tomography (FDG PET/CT) during the last week of treatment, for indicating the development of grade ≥ 2 RP within 4 months of CRT completion...

OBJECTIVE: The purpose of this study was to assess the diagnostic significance of CT patterns that cannot be classified according to current idiopathic pulmonary fibrosis (IPF) guidelines and of specific findings of the inconsistent with usual interstitial pneumonitis (UIP) pattern. MATERIALS AND METHODS: Subjects with a multidisciplinary diagnosis of interstitial lung disease who had undergone surgical lung biopsy and chest CT within 1 year of each other were included in the study...

BACKGROUND: Immune checkpoint inhibitors are a new standard of care for patients with advanced non-small-cell lung cancer (NSCLC) without EGFR tyrosine kinase or anaplastic lymphoma kinase (ALK) genetic aberrations (EGFR-/ALK-), but clinical benefit in patients with EGFR mutations or ALK rearrangements (EGFR+/ALK+) has not been shown. We assessed the effect of durvalumab (anti-PD-L1) treatment in three cohorts of patients with NSCLC defined by EGFR/ALK status and tumour expression of PD-L1...

Koji is a fermenting agent used in many traditional Japanese foods , and Aspergillus oryzae is the most frequently used microorganism in koji production. Few cases of hypersensitivity pneumonitis due to A. oryzae have been reported. However, physicians should recognize the disease because of the increasing globalization of food production.

Lung cancer remains the leading cause of cancer-related mortality worldwide. To formulate effective treatment strategies and optimize patient outcomes, accurate staging is essential. Lung cancer staging has traditionally relied on a TNM staging system, for which the International Association for the Study of Lung Cancer (IASLC) has recently proposed changes. The revised classification for this eighth edition of the TNM staging system (TNM-8) is based on detailed analysis of a new large international database of lung cancer cases assembled by the IASLC for the purposes of this project...

BACKGROUND: A high incidence and mortality of plague in the past two decades occurred in the Qinghai-Tibet Plateau, China. High dose streptomycin (6-8 g/d) remained the first practical strategy for controlling the progressive, vicious clinical circumstances for patients with pneumonic plague in the Plateau, as opposed to the routine dosage recommended by the World Health Organization. To investigate whether patients with pneumonic plague truly required a large dosage of streptomycin in the hypoxic environment of the Tibetan Plateau, we investigated the hypothesis that hypoxic environment would change the pharmacokinetics of streptomycin in vivo...

Radiation therapy has been used to treat over 70% of thoracic cancer; however, the method usually causes radiation pneumonitis. In the current study, we investigated the radioprotective effects of HSP27 inhibitor (J2) on radiation-induced lung inflammation in comparison to amifostine. In gross and histological findings, J2 treatment significantly inhibited immune cell infiltration in lung tissue, revealing anti-inflammatory potential of J2. Normal lung volume, evaluated by micro-CT analysis, in J2-treated mice was higher compared to that in irradiated mice...

PURPOSE: Stereotactic ablative body radiotherapy (SABR) represents an exciting, tolerable, and highly effective form of radiotherapy. Ongoing investigations into the interactions between radiotherapy and the immune system have uncovered new mechanisms that can be exploited to improve efficacy. We determined whether baseline or posttreatment immune parameters could predict disease control and toxicity in stage I non-small-cell lung cancer (NSCLC) patients treated with SABR. PATIENTS AND METHODS: Peripheral blood samples were collected from 62 patients 24 hours before treatment and within 4 weeks after treatment for lymphocyte subset count analysis...

Radiation injury to the lung is the result of acute and chronic free radical formation, and there are currently few effective means of mitigating such injury. Studies in rodents indicate that superoxide dismutase mimetics may be effective in this regard; however, studies in humans or large animals are lacking. We hypothesized that post-exposure treatment with the lipophilic mitochondrial superoxide dismutase mimetic, MnTnHex-2-PyP5+ (hexyl), would reduce radiation-induced pneumonitis and fibrosis in the lungs of nonhuman primates...

Chronic progressive diseases of the central nervous system such as granulomatous amoebic encephalitis, amoebic keratitis, amoebic pneumonitis and also skin infections caused by free-living amoebae (Acanhamoeba spp.) are a significant challenge for pharmacotherapy. This is due to the lack of effective treatment because of encystation, which makes the amoebae highly resistant to anti-amoebic drugs. A very inter- esting and promising source of future drugs in this area are plant materials obtained not only from the habitat but also from plant in vitro culture as an alternative source of biomaterials...
