In fact, only through CT, it is difficult to diagnose whether it is lung cancer, and there are different types of lung cancer, treatment methods are also different, and can not check out a suspected lesion, directly arrange surgery.
small cell lung cancer accounts for 15% – 20% of lung cancer. It has a high degree of malignancy, rapid growth, metastasis very early, and poor prognosis. Most patients are in extensive stage when they are diagnosed. When the tumor spreads beyond the supraclavicular area, it belongs to extensive stage.
this also makes it difficult for small cell lung cancer to achieve complete treatment through surgery. Fortunately, it is more sensitive to chemotherapy. Generally, platinum combined with etoposide combined with local radiotherapy can significantly improve the survival of patients.
non small cell lung cancer accounts for 80% ~ 85% of the total number of lung cancer, including squamous cell carcinoma, adenocarcinoma and large cell carcinoma. The prognosis of different types of lung cancer is also different. Compared with small cell lung cancer, the growth rate of non-small cell lung cancer is relatively slow, and the proliferation and metastasis are also relatively late.
smoking is the most important risk factor for non-small cell lung cancer. Early detection showed that the 5-year survival rate of stage I patients could reach 80% after surgery combined with radiotherapy and chemotherapy.
However, in the early stage of the disease, the patient’s symptoms are not typical. If the patient has entered the middle and late stage and has spread and metastasis, the surgical treatment method can not cure the tumor. In addition, if the patient is older and has poor cardiopulmonary function, and can not tolerate surgery, the only palliative treatment of the tumor through radiotherapy and chemotherapy can improve the patient’s symptoms.
therefore, even for lung cancer, the prognosis and treatment can not be confirmed by a single CT. The specific treatment can be determined according to the pathological classification, which can be confirmed by puncture biopsy or pathological examination during operation, and then the relevant chemotherapy can be guided according to the pathological conditions.
