Pneumonitis

The goal of this clinical trial is to learn if using an incentive spirometer can reduce lung problems in people with advanced lung cancer who are receiving chemotherapy and radiation therapy. The main questions the study aims to answer are: Does using an incentive spirometer lower the chances of developing lung inflammation (pneumonitis)? Does it improve overall survival and quality of life? Participants will: Use an incentive spirometer, a device that helps with deep breathing, 10 times every hour while awake. Continue using the spirometer daily during treatment and for up to three months after treatment. Complete quality of life assessments at the start of the study and at 3, 6, and 12 months. Researchers will compare the results to see if the incentive spirometer helps reduce lung problems and improves participants\' well-being during and after their cancer treatment.

The introduction of immune checkpoint inhibitors (immunotherapy) that stimulate our immune system to recognize and attack cancer cells has been one of the most exciting advances in oncology over the last decade. These medications are now employed across almost half of cancer types and settings, however they come with a cost. In some patients, instead of attacking cancer cells alone, the stimulated immune system damages healthy tissues (immune related adverse events), with one of the most severe and potentially deadly such complications being immune attack on the lungs, or checkpoint inhibitor pneumonitis (CIP). When treated promptly with oral or intravenous steroids, acute CIP improves in many cases, however for approximately one-fifth of patients the lung inflammation is difficult to control, resulting in recurrent shortness of breath, the need for extended courses of oral or intravenous steroids, impacting quality of life and cancer therapy decisions. The goal of the trial is to assess whether use of inhaled steroids, a type of medication commonly used in asthma patients, for one year after a first diagnosis of CIP may help the lung inflammation resolve and not return, without the repeated use of oral or intravenous medications that carry more side effects.

A multicenter, exploratory clinical research, to map the radiation or immune checkpoint inhibitor pneumonitis in patients with alveolar lavage single-celled map. Find out the pathogenesis and prevention strategies of radiation or immune checkpoint inhibitor pneumonitis. Specific treatment is given based on the recommendation of the treatment guidelines for radiation or immune checkpoint inhibitor pneumonitis and the results of single cell sequencing, which will become a new technology for clinical application.

This study intends to evaluate the efficacy and safety of eravacycline-based combination therapy in real words for Chinese patients with CRAB pneumonia, providing data reference for clinical treatment of CRAB pneumonia.
