A Study to Learn About Patients With Non-Small Cell Lung Cancer (NSCLC) Who Took Lorlatinib as Their First Treatment

The main purpose of the study is to learn how the lung cancer medicines work. The study also looks into treatment sequence of these medicines. This study is performed outside of clinical studies in a database in the United States in patients with metastatic or advanced non-small cell lung cancer. Non-small cell lung cancer is a group of lung cancers named for the kinds of cells found in the cancer and how the cells look under a microscope. Metastasis is when the cancer cells spread to other parts of the body. Advanced cancer is when the patient is diagnosed with stage III or stage IV cancer. This study includes patient's information from the database who: * Are aged 18 years or older. * Are confirmed to have metastatic non-small cell lung cancer on or after 1 January 2021. * Have a positive Anaplastic Lymphoma Kinase (ALK) gene mutation or rearrangement. A gene is a part of your DNA that has instructions for making things your body needs to work and a mutation or rearrangement can cause the gene not to work properly. ALK is a protein that helps control cell growth. * Received lorlatinib as their first treatment. All participants in this study had received the study medicine lorlatinib. It is a tablet that is taken by mouth at home. They continued to take the study medicine until their cancer was no longer responding. The study will look at the experiences of people receiving the study medicine. The study is based on information collected from Flatiron Health's Advanced NSCLC Panoramic dataset which includes: \- Diagnosis, cancer stage at diagnosis, date of diagnosis, birth year, type of medicinal treatment, date of treatment start and end, age, gender, etc.

Efficacy and Safety of Ensartinib in Neoadjuvant Therapy for Stage IIA - IIIB (Operable or Potentially Operable) ALK-Positive Lung Adenocarcinoma ：A Multicenter, Real-World Clinical Study

According to the Global Cancer Statistics 2022 report, lung cancer is the most common type of cancer (12.4% of the total) and the leading cause of cancer deaths (18.7% of total cancer deaths). According to the pathological classification of patients, lung cancer is divided into small cell lung cancer and non-small cell lung cancer, of which non-small cell lung cancer (NSCLC) accounts for 80-85% of all lung cancer. Surgery is the preferred treatment for patients with early-stage lung cancer, according to the 2024 CSCO Guidelines. However, most patients have the possibility of recurrence and metastasis after surgery. The 5-year survival rate of patients with stage IA NSCLC is 80%-90%, but the 5-year survival rate of patients with stage ⅢB NSCLC drops to 40%. Neoadjuvant therapy has become an important part of the treatment of non-small cell lung cancer (NSCLC) in order to prolong the survival of patients. In the past few years, many driver genes of NSCLC have been identified, and anaplastic lymphoma kinase (ALK) is one of them. ALK was first identified in anaplastic large cell lymphoma (ALCL). Studies at home and abroad have shown that ALK-rearranged (positive)NSCLC accounts for about 3%-7% of all NSCLC patients. Many studies have suggested that ALK-TKI is clinically feasible as a neoadjuvant therapy for ALK positve patients with locally advanced NSCLC. The investigators designed this study to explore the efficacy of enshatinib neoadjuvant therapy in patients with stage IIA to III ALK-positive lung adenocarcinoma
