What Is Small Cell Carcinoma?
Small cell lung cancer accounts for about 15% -20% of bronchogenic lung cancer. When small cell lung cancer is diagnosed, about 30% of patients with tumors are in the limited stage, and the rest are in the extensive stage. It is widespread when the tumor has spread beyond the supraclavicular region period. Compared with other types of lung cancer, small cell lung cancer has better chemotherapy and radiotherapy effects. However, because small-cell lung cancer is likely to have spread extensively at the time of diagnosis, small-cell lung cancer is often difficult to cure [1] .
Small Cell Lung Cancer
- Small cell lung cancer accounts for about 15% -20% of bronchogenic lung cancer. When small cell lung cancer is diagnosed, about 30% of patients with tumors are in the limited stage, and the rest are in the extensive stage. It is widespread when the tumor has spread beyond the supraclavicular region period. Compared with other types of lung cancer, small cell lung cancer has better chemotherapy and radiotherapy effects. But because the tumor is likely to have spread extensively at the time of diagnosis, small cell lung cancer is often difficult to cure [1]
- Lung cancer can show clinical symptoms and may occasionally be found on chest imaging. Symptoms and signs of lung cancer patients can be caused by local primary lesions, compression of adjacent thoracic structures, distant metastases, or paraneoplastic syndromes. Common symptoms include increased cough, shortness of breath, and difficulty breathing; other symptoms include:
- Chest pain
- 2. Hoarse
- 3. fatigue
- 4. Loss of appetite
- 5. Weight loss
- 6. Coughing up blood
- Choosing a patient's treatment plan depends on histological examination, stage of disease, overall health and comorbidities. The focus of examination on patients with suspected SCLC is differential diagnosis and judgment of disease severity.
- Cancer diagnosis methods include:
- Medical history
- 2.
- Small cell lung cancer (SCLC) accounts for 15% to 20% of all lung cancers, mainly including three subtypes, namely lymphocyte (oat cell) type and intermediate cell type (fusiform, polygonal and other) and mixed types. There were no significant differences in prognosis among the three subtypes. Most small cell lung cancers are related to smoking, and the rest may be related to the environment or genetics. Clinical manifestations are similar to non-small cell lung cancer (NSCLC), such as
- The clinical manifestations of small cell cancer are mainly irritating dry cough, sputum, chest tightness, shortness of breath, and chest pain. The central type of respiratory symptoms are more obvious than the peripheral type. Peripheral lung cancer has no other clinical symptoms except chest pain. And small cell carcinoma can also cause hyponatremia [3]
- Although small cell lung cancer is highly sensitive to chemotherapy and radiotherapy, most patients eventually metastasize and spread. Almost all patients with small cell lung cancer have a tendency to spread throughout the body. Therefore, combined chemotherapy and chest radiotherapy are the main treatments for this disease. Surgical resection is only performed in a limited number of patients with limited period. The prognosis of this type of tumor is extremely poor. Systemic chemotherapy can definitely prolong survival and improve symptoms, but since the remission period of drug resistance is usually less than 1 year, comprehensive treatment is the key to achieving radical cure [2] .
