Pneumonitis
It can be caused by a variety of factors, including infections, exposures to certain chemicals or dusts, and autoimmune disorders.
Symptoms of pneumonitis may include cough, shortness of breath, fever, and chest pain.
Accurate diagnosis and identification of the underlying cause are important for effective treatment.
PubCompare.ai can help researchers optimize their pneumonitis studies by enabling effortless access to the most relevant protocols from literature, preprints, and patents, while providing accuarate comparisons to identify the best approaches.
This can enhance reproducibility and accuracy in pneumonitis research.

Nonbinary outcomes were dichotomized, for example, overall survival was translated into 2‐yr overall survival in the dataset of Carvalho et al.10 (link). Missing data were imputed for training and test sets (the splitting of datasets into training and test sets is described in Section
In addition, to better reflect the cost of first-line and second-line treatments in real-world settings, the duration of these treatments were adjusted based on the median treatment cycles reported in the respective clinical trials (Gandhi et al., 2018 (link); Wu et al., 2019 (link); Zhou et al., 2021b (link)), to account for the fact that patients may discontinue first-line and second-line treatments due to unacceptable toxicity, consent withdrawal, or investigator decision, in addition to progression and death. The cost of subsequent third-line therapy, routine follow-up, BSC, and end-of-life care came from a published study (Liu et al., 2020b (link)).
The cost of commonly reported grade III/IV AEs with an incidence of >5% were incorporated in the model, including neutropenia, thrombocytopenia, and anemia (Gandhi et al., 2018 (link); Zhou et al., 2021b (link)). Although some common immune-related AEs related to camrelizumab were reported, such as reactive capillary endothelial proliferation and immune-related pneumonitis, their costs were not considered in this model because of their low grade III/IV incidence. The costs per patient corresponding to each AE were sourced from published literature (

Drug-related pneumonitis showing new diffuse ground-glass opacities, consolidation, and traction bronchiectasis, indicative of a diffuse alveolar damage pattern (
This study cohort was created to conduct two primary evaluations. The first primary analysis aimed to investigate the early incidence of pneumonitis and its association with survival, as reported previously9 (link). The present report is a second prespecified primary analysis to determine characteristics, prognostic factors, and clinical course of pneumonitis in patients who developed pneumonitis associated with combination therapy with updated data.
Patients aged older than 20 years were enrolled if they had pathologically confirmed metastatic non-squamous NSCLC without sensitizing epidermal growth factor receptor or anaplastic lymphoma kinase mutations and had received a combination of platinum, pemetrexed, and pembrolizumab (combination therapy) as the first-line treatment.
Smoking status was categorized as never (never smoked), current (smoked within 1 year of diagnosis), and former (other smoking status). PD-L1 expression was assessed using the PD-L1 IHC 22C3 pharmDx assay (Agilent Technologies, Santa Clara, CA, USA) and was categorized based on the tumor proportion score.
This study was approved by the Ethical Review Board or Institutional Review Board of each participating institute including Wakayama medical university Ethics Committee. This study was performed in accordance with the principles of the Declaration of Helsinki. We attained adequate consent for using electronic patient records through an opt-out strategy owing to the study’s retrospective nature. All images were obtained with informed consent (or formal waiver of consent) with approval by the Ethics Committee of our hospital. This study followed the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) reporting guideline for cohort studies.
The grade of pneumonitis was determined by the treating pulmonologist or oncologist and two independent pulmonologists according to the CTCAE version 5.0. Mild and severe pneumonitis were defined as grade ≤ 2 and grade ≥ 3, respectively.
Initial treatment for pneumonitis was defined as steroid and immunosuppressive agents within 1 week after the development of pneumonitis. Steroid doses were expressed as prednisone equivalents. Additionally, we defined a high steroid dose as a prednisolone equivalent dose of ≥ 1.0 mg/kg12 (link).
Worsening of respiratory status due to pneumonitis was defined as an increase in either oxygen supplementation or category of oxygen supplementation for pneumonitis regardless of the presence or absence of treatment for pneumonitis; additionally, this status was confirmed. The categories of oxygen supplementation were as follows: (1) no oxygen supplementation; (2) oxygen supplementation but not requiring HFNC or NRB (simple oxygen supplementation); (3) HFNC or NRB; (4) non-invasive positive-pressure ventilation; (5) intubation with mechanical ventilation; or (6) death due to respiratory failure associated with pneumonitis14 (link),15 (link).
Improvement of pneumonitis was defined as improvement in oxygenation, respiratory symptoms, and lung field shadowing in patients who received steroids at a prednisolone equivalent dose of ≤ 10 mg11 (link).
Relapsed pneumonitis was defined as pneumonitis after the confirmation of improvement and before the start of new anticancer therapy other than pembrolizumab, a platinum agent, and pemetrexed. Relapsed pneumonitis cases were divided into pneumonitis before and after the rechallenge of combination therapy.
