The main risk factor is tobacco, followed by radon. The main histological subtypes are adenocarcinoma and squamous cell carcinoma. In most cases, patients are diagnosed with NSCLC in advanced stages (III-IV), usually after the onset of respiratory and/or constitutional symptoms. The first diagnostic test is usually a chest X-ray in which a pulmonary nodule is observed, after which staging should be completed with a thoracic-abdominal-pelvic computed tomography (CT) scan (and a positron emission tomography (PET-CT) scan in case of localized or locally advanced disease) and a cranial CT scan. The histological diagnosis should be confirmed by performing a biopsy. Enough tissue should be obtained not only for cytomorphological diagnosis (histological subtype), but also for the biomarker study (molecular diagnosis and PD-L1). In the last decade, significant advances have been made in the treatment of patients with NSCLC with the emergence of targeted therapies and immunotherapy, which have achieved a significant improvement in survival. The treatment of choice will depend on the patient's characteristics (general condition, previous diseases, etc.) and preferences as well as on the tumor characteristics, the histological subtype, and whether targeted therapies exist or not (depending on the biomarker results).</div></div>","PeriodicalId":100912,"journal":{"name":"Medicine - Programa de Formación Médica Continuada Acreditado","volume":"14 27","pages":"Pages 1580-1594"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143591717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The manner in which they are regulated has repercussions on cellular responses and, as a consequence, on the appropriate or inappropriate behavior of the immune system. Therefore, they have the potential to cause serious pathological abnormalities. This brief review will analyze in a simple way the classification and description of the basic behavioral mechanisms of some of the most relevant cytokines and soluble factors involved in the communication and response of the cells that form the immune system. The use of biologic drugs such as immunotherapy to regulate the behavior of cytokines and growth factors in different inflammatory diseases, infections, autoimmunity, or cancer is growing every day. Knowledge of the complex, distinct mechanisms that underlie the behavior of cytokines helps in understanding their involvement in these diseases, why they are therapeutic targets, and how new biologic therapies work.</div></div>","PeriodicalId":100912,"journal":{"name":"Medicine - Programa de Formación Médica Continuada Acreditado","volume":"14 28","pages":"Pages 1673-1687"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143739991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
