Today we performed another thoracoscopic left lower lobe dorsal segment resection for a 67 year old female with early stage lung cancer (lesion size about 2.0 cm). I think if all cases like this were treated at an “early” stage, patients would have a better survival and quality of life. November is National Lung Cancer Awareness Month. What should we focus on here? This is not an easy topic. Because, indeed, it is not easy whenever this topic is touched upon. Su Lei, Department of Thoracic Surgery, Xuanwu Hospital, Capital Medical University For one, although surgical techniques and chemotherapeutic drug treatments have been developed rapidly, the overall survival rate of lung cancer patients is still not satisfactorily improved. Secondly, the increasingly serious pollution, not only air pollution including haze but also other pollution, has greatly increased the risk factors of lung cancer. Therefore, what we can do is to detect “early” lung cancer through early screening. That is, clinicians and the public need to work together to guard this line of defense. Once a lung nodule or other lesion is detected, it is important not to refuse the necessary tests, sometimes including traumatic tests, on the grounds that “I don’t feel anything” or “I don’t have a cough”. If you have time, please read “Do I need surgery for a small nodule shadow in my lung? , “Asymptomatic peripheral lung lesions, do they need surgery”, “Minimally invasive surgical treatment of pulmonary nodules”, “Diagnosis and management of pulmonary ground glass shadow”, “What to do if pulmonary nodules are found on physical examination? -Clinical treatment strategies for pulmonary nodules‖ and other short articles. The reason why we repeatedly publish these articles is that most of the outpatients we meet do not recognize the danger of nodules and take a chance. We must rely on scientific and standardized examination and treatment. These are my own thoughts. Whenever we treat a case of “early stage” lung cancer, we also feel a little lucky for them (nothing else —- compared with advanced stage patients). Because the 5-year survival rate for “early stage” lung cancer patients is 85-90%, and most of them do not need chemotherapy or radiotherapy. We should work together.
