Lung cancer is one of the most common forms of cancer worldwide and was considered virtually incurable for decades. However, medical advances in recent years – particularly in personalized medicine – have fundamentally changed this diagnosis. New approaches in diagnostics and therapy are increasingly making it possible to treat lung cancer as a <\/span>chronic illness<\/b> treatment.<\/span><\/p>\n

Modern drug-based tumor therapies, targeted treatment approaches based on molecular markers and the integration of innovative procedures such as immunotherapy have significantly improved the prognosis for many patients. With the right therapy, patients can not only survive for a long time, but in many cases lead an almost normal life. <\/span><\/p>\n

This article highlights the latest developments in the diagnosis and treatment of lung cancer – with a particular focus on <\/span>predictive markers<\/b>, <\/span>targeted therapies<\/b> and the role of personalized medicine.<\/span><\/p>\n

Lung cancer: A new era of personalized treatment<\/b><\/h2>\n

From universal therapy to individualized medicine<\/b><\/h3>\n

Lung carcinomas are no longer a homogeneous disease, but a spectrum of different subtypes defined by their molecular characteristics. Thanks to the analysis of predictive markers, it is now possible to develop tailored therapies that specifically target the genetic changes in the tumor. <\/span><\/p>\n

Predictive markers in lung cancer<\/b><\/h3>\n

Molecular tests enable the identification of specific genetic changes or proteins that serve as predictive markers. These markers determine which therapies are most effective and have a positive influence on the prognosis. <\/span><\/p>\n

    \n
  1. \n

    EGFR (Epidermal Growth Factor Receptor)<\/b><\/h4>\n<\/li>\n<\/ol>\n
      \n
    • Mutations in the EGFR gene are detectable in around 10-15% of NSCLC (non-small cell lung cancer) patients.<\/span><\/li>\n
    • Therapy options:<\/b> Tyrosine kinase inhibitors (TKIs) such as osimertinib, gefitinib and erlotinib block the EGFR signaling pathway and inhibit tumor growth.<\/span><\/li>\n<\/ul>\n
        \n
      1. ALK (Anaplastic Lymphoma Kinase)<\/b><\/li>\n<\/ol>\n
          \n
        • ALK translocations occur in about 5 % of NSCLC patients.<\/span><\/li>\n
        • Therapy options:<\/b> ALK inhibitors such as crizotinib, alectinib and lorlatinib show high efficacy in ALK-positive tumors.<\/span><\/li>\n<\/ul>\n
            \n
          1. \n

            ROS1<\/b><\/h4>\n<\/li>\n<\/ol>\n

                • therapy option:<\/b> Sotorasib is a specific KRAS-G12C inhibitor.<\/span><\/li>\n<\/ul>\n
                    \n
                  1. \n

                    PD-L1 (Programmed Death-Ligand 1)<\/b><\/h4>\n<\/li>\n<\/ol>\n
                      \n
                    • PD-L1 expression on tumor cells correlates with the response to immunotherapies such as pembrolizumab and nivolumab.<\/span><\/li>\n<\/ul>\n
                        \n
                      1. \n

                            Targeted therapies<\/b><\/h3>\n<\/li>\n<\/ol>\n

                            The introduction of targeted drugs has revolutionized the treatment of lung cancer. These therapies specifically target molecular changes that drive tumor growth. <\/span><\/p>\n

                              \n
                            • Tyrosine kinase inhibitors (TKIs):<\/b> Block signaling pathways that are activated by mutations in genes such as EGFR, ALK or ROS1.<\/span><\/li>\n
                            • Angiogenesis inhibitor:<\/b> Bevacizumab prevents the formation of new blood vessels that tumors need for their growth.<\/span><\/li>\n<\/ul>\n

                                Immunotherapies use the body’s own immune system to attack cancer cells. Checkpoint inhibitors such as pembrolizumab, nivolumab or atezolizumab inhibit the immune blockade of tumor cells and thus strengthen the body’s natural defences. <\/span><\/p>\n

                                Advantages:<\/b><\/p>\n

                                    Chemotherapy<\/b><\/h3>\n<\/li>\n<\/ol>\n

                                    Although chemotherapy is increasingly being supplemented by targeted therapies and immunotherapies, it remains an important part of treatment – especially for patients without specific molecular markers.<\/span><\/p>\n

                                      \n
                                    • Platinum-based regimens:<\/b> Cisplatin and carboplatin are proven standard therapies in first-line treatment.<\/span><\/li>\n<\/ul>\n

                                      Diagnostics: the key to personalized treatment<\/b><\/h2>\n

                                      The choice of optimal therapy depends on precise diagnostics. Modern methods make it possible to characterize tumours at a molecular level and adapt targeted therapies individually. <\/span><\/p>\n
