What is the introduction of small cell lung cancer

If you want to cure small cell lung cancer, you have to understand all the contents of small cell lung cancer, because this disease is a new term for many people, and they know very little about it. Many patients with small cell lung cancer think that they have lost hope and longing for life because of lung cancer. Such low-level emotions will lead to the deterioration of the disease and are not good for treatment. So let me briefly talk about the introduction of small cell lung cancer.

Small cell lung cancer accounts for 15% of all lung cancers, and about 98% of small cell lung cancers are related to smoking. The rest are related to environmental and genetic factors.

Clinical manifestations

Cough, dyspnea, weight loss and weakness, with or without obstructive pneumonia, are often caused by large masses at the hilum of the lung and enlarged mediastinal lymph nodes. Neurological and endocrine paraneoplastic syndromes caused by tumors include Lan-Evans syndrome, cancer-related encephalomyelitis and sensory neuropathy, as well as Cushing syndrome and hyponatremia.

Prognostic factors

Poor physical condition, extensive stage, weight loss, multiple tumor invasion and excessive tumor size are all important adverse prognostic factors. In the limited stage, female, under 70 years old, stage I and normal LDH have a better prognosis; in the extensive stage, normal LDH and single metastatic lesion have a good prognosis, the number of involved organs is negatively correlated with the prognosis, and the prognosis of liver metastasis is worse. The prognosis of patients with endocrine paraneoplastic syndrome is often poor.

Inspection method

Physical examination, chest X-ray, chest and abdominal CT, head MRI, bone scan. PET scan if necessary. About 30% of patients with normal alkaline phosphatase levels or asymptomatic patients have positive bone scans; about 10% to 15% of new patients have central nervous system metastases on head CT or MRI scans, and 30% of these patients have no symptoms. Because small cell tumors grow rapidly, most patients develop typical symptoms within 8 weeks, and the disease progresses significantly faster afterwards. Do not spend too much time on examinations and staging and delay treatment.

The above is the content of the introduction to small cell lung cancer. Understanding small cell lung cancer can better start from the patient’s own disease. Specific analysis of specific problems is of great significance for the prevention and treatment of small cell lung cancer.
