Core Viewpoint - The article emphasizes the urgent need for early screening and prevention of lung cancer, highlighting the rising incidence and mortality rates in China, and the importance of public awareness and multi-disciplinary approaches in treatment [1][2][4]. Group 1: Lung Cancer Statistics - Lung cancer accounts for approximately 1.06 million new cases annually in China, representing 22% of all malignant tumors, with a death toll of 730,000, making it the leading cause of cancer-related deaths [2]. - The early cure rate for lung cancer is nearly 100%, but most patients are diagnosed at advanced stages, underscoring the critical need for early detection [2]. Group 2: High-Risk Groups and Screening - High-risk populations for lung cancer include smokers, individuals with occupational exposure, those with a family history of lung cancer, and patients with chronic obstructive pulmonary disease [2]. - It is recommended that individuals over 40 years old undergo annual low-dose chest CT screenings to facilitate early detection [2]. Group 3: Symptoms and Diagnosis - Clinical symptoms of lung cancer can vary widely, including cough, hemoptysis, chest pain, and headaches, with some patients showing no obvious symptoms [2]. - Diagnosis involves imaging tests such as chest CT and PET-CT, along with tissue biopsies and genetic testing to guide treatment decisions [2]. Group 4: Complications and Treatment Strategies - Meningeal metastasis is a severe complication of lung cancer, with a survival period of only 4-6 weeks; early warning signs include headaches and nausea [3]. - Treatment options include surgery, radiotherapy, chemotherapy, targeted therapy, and immunotherapy, tailored to the patient's condition and tumor characteristics [3][4]. Group 5: Multi-Disciplinary Approach - The integration of various specialties in lung cancer treatment has been shown to improve patient outcomes, with personalized treatment plans developed through multi-disciplinary discussions [4]. - Monitoring of liver and kidney functions, as well as blood counts, is essential during treatment to manage potential side effects [4]. Group 6: Prevention and Public Awareness - Preventive measures include smoking cessation, limiting alcohol intake, and maintaining a healthy lifestyle, along with regular screenings for high-risk groups [4]. - The article calls for collective efforts from society to enhance public awareness, improve early screening, and promote standardized treatment to increase survival rates and quality of life for lung cancer patients [4].
