Clinical work and online consultation can meet many early lung nodules, and make a brief summary of early lung cancer screening and imaging examinations. Literature studies suggest that the 5-year survival rate of stage I-IV lung cancer is quite different. The survival rate for stage I lung cancer can be 70-90%, but only about 5% for stage IV lung cancer. The early detection of lung cancer shows a strong need to reduce the mortality rate of high-risk groups. Recommended high-risk groups: age > 45 years old and one of the risk factors for lung cancer, such as smoking more than 20 packs per year, long-term exposure to secondhand smoke, and history of exposure to oil smoke. The CSCO guidelines recommend low-dose spiral CT as a Class I recommendation. Compared with X-ray, CT chest is more sensitive and is widely used in the follow-up and diagnosis and treatment of lung cancer. Therefore, it is recommended that you do CT in the next outpatient clinic or consultation, but don't think that the doctor's level is not good.
For patients with no nodules in the initial screening or patients with nodules that do not require clinical intervention for the time being, it is recommended to re-examine them once every 1-2 years. When imaging studies show an abnormal nodule, which may be extremely malignant, or an airway mass, active clinical intervention is recommended to further confirm the diagnosis.
Pathological diagnosis: early and mid-stage lung cancer is mainly intraoperative rapid freezing pathology, which is what we often call "rapid pathology" in preoperative conversations, but it is only a preliminary diagnosis, and ultimately depends on the conventional pathological diagnosis after surgery, and sometimes the results of the two will be different. Postoperative pathology is our gold standard, that is, everything is based on it, and sometimes it is difficult to distinguish between them, and it is necessary to carry out histochemistry and dye the section, which takes longer. So you know, next time, don't rush to ask the doctor why the pathology hasn't come out yet, because it may be waiting for staining.
Early and mid-stage lung cancer staging: clinical staging: ** or a staging before surgery, relying on examinations and tests to give a clinically determined stage. Pathological staging: the precise staging given by conventional pathology + preoperative examination after surgery. The pathological stage provides guidance for our subsequent targeting** or chemoradiotherapy.
