Its biological understanding is currently framed by two principal models: the multistep model, which involves the progressive accumulation of genetic alterations often associated with tobacco exposure, and the oncogene addiction model, in which tumor growth is critically dependent on a single genetic driver. Advances in genomics have enabled more precise identification of mutations underlying tumor initiation and progression, as well as factors shaping therapeutic response. Certain precancerous lesions may progress to invasive disease through specific genetic events, modulation of the immune microenvironment, or external influences such as pollution. Emerging evidence indicates that pollutants can promote the emergence or activation of pre-existing tumor clones via inflammatory pathways. The oncogene addiction paradigm has facilitated the development of effective targeted therapies for defined patient subgroups, although therapeutic efficacy is frequently limited by mechanisms of resistance. Large-scale sequencing studies have further revealed the pronounced heterogeneity of lung tumors, characterized by complex clonal evolution shaped by treatment pressure, immune surveillance, and environmental factors. This heterogeneity likely underlies both intrinsic and acquired resistance to targeted agents. Within the framework of precision medicine, these insights provide a foundation for optimizing therapeutic strategies and may inform the development of novel approaches to prevention and longitudinal disease monitoring.</div></div>","PeriodicalId":53645,"journal":{"name":"Revue des Maladies Respiratoires Actualites","volume":"17 2","pages":"Pages 2S15-2S24"},"PeriodicalIF":0.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145236483","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}

It would imply an intermediary state between a cancer tumor with diffuse metastatic effusion and a tumor purely localized to the primitive organ (i.e. the lung), that is to say a cancer disease with a limited number of metastatic sites, the definition according to different authors, ranging from 1 to 5 metastases, most often in no more than 1 to 2 organs. Such concepts emerged from mainly retrospective studies, regional or national databases, or meta-analyses, most of them before the targeted therapies and modern immunotherapy eras, suggesting that adding locoregional treatments (surgery, radiotherapy, thermos-ablation, radio-frequence) to systemic treatments would increase survival, although all those studies are debatable, because of their retrospective design. Prospective trials are still rare, essentially with phase 2 trials, often accruing patients with different cancer and organ types, with modest sample size of patients with NSCLC, limiting their meaning. Because of the unprecedently observed efficacy of new systemic targeted therapies and immunotherapy in NSCLC, new concepts also emerged such as oligo-progression, oligo-persistence or residual tumor disease, although previously described for other tumor types. The current review aims to precise some complex and sometimes contradictory definitions, to synthetize the results of the main retrospective studies and meta-analyses, to examine the rare prospective studies and decipher the current situation cases that could occur. Actually, the medical reasoning differs according to the addictive mutational tumor status with efficient available targeted therapy, or in patients without addictive mutation, according to immuno-or immunochemotherapy response, or according to the timepoint, at diagnosis, during treatment, or after the two years of immunotherapy, all these different situations leading to possibly different approaches, the evidence from literature being still fragmentary.</div></div>","PeriodicalId":53645,"journal":{"name":"Revue des Maladies Respiratoires Actualites","volume":"17 2","pages":"Pages 2S127-2S142"},"PeriodicalIF":0.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145236546","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}

Its global prognosis is poor, without validated curative treatment to date. Diagnosis relies ideally on thoracoscopy with pleural biopsies, ± combined with (immediate) talc pleurodesis. Surgery with curative intent, included with multimodal treatment and restrained to highly selected patients, was recently rechallenged. As frontline treatment, standard pemetrexed/platinum-based chemotherapy was lightly improved by addition of bevacizumab. It is currently challenged by the immunotherapy combination of Nivolumab + Ipilimumab, and perhaps soon by combinations of chemotherapy + immunotherapy. No standard treatment is firmly validated beyond first line treatment, even if anti-PD-1/PD-L1 ± anti-CTLA-4 checkpoint inhibitors also exhibited some interesting results in this setting, in phase II and III clinical trials. Therefore, the search of new treatments, strategies and biomarkers is a crucial goal, and recruitment of patients in clinical trials strongly encouraged.
