What are the examination items for small cell lung cancer

What are the examination items for small cell lung cancer? The most important thing for people with small cell lung cancer is early detection and early treatment. Some irregular hospitals may cause misdiagnosis due to incomplete examinations. So what are the examination items for small cell lung cancer? Let's learn about it with us.

Examination items: blood routine, CT, X-ray, sputum examination

1. Chest computerized tomography (CT): It can show lesions that cannot be found by ordinary X-ray examination, and show the scope and degree of involvement of the hilar lymph nodes and mediastinum.

2. Fiberoptic bronchoscopy: It can observe the location, size and extent of the tumor infiltrating into the bronchial cavity, and obtain tissue for pathological examination. Endobronchial ultrasound (EBUS) is a new technology. For lesions with only airway compression but no intracavitary tumors, this examination can help clarify the extent of the lesion and improve the accuracy of transmural biopsy.

3. Magnetic resonance imaging (MRI): It is not as good as CT in detecting small lung lesions, but it can more clearly show the relationship between the tumor and large blood vessels. When determining whether there is intracranial metastasis, enhanced MRI is the first choice.

4. Positron emission tomography (PET): Whole-body PET is significantly more accurate than CT and radionuclide bone scanning in identifying lung masses, lymph nodes or distant metastases.

5. Sputum cytology examination: The positive rate is related to the location and size of the tumor, the quality of the sputum, and whether there is concurrent infection. The detection rate of central lung cancer is higher, but it is difficult to determine the type, and it is not recommended for use at present.

6. Tumor VIP receptor imaging: VIP is a neurotransmitter composed of 28 amino acids with multiple functions. It can regulate the proliferation and differentiation of normal and tumor cells through its receptors. VPAC (VIP receptor) is widely present in various normal and tumor tissues, but its expression density in tumor tissue is much greater than that in normal tissue, which lays the foundation for radionuclide-labeled VIP receptor imaging. This imaging has been applied to the diagnosis, staging, treatment selection and prognosis evaluation of various tumors.

Prevention of lung cancer is better than cure, and there are three levels of prevention. The first level of prevention is for healthy people, mainly including not smoking and staying away from secondhand smoke pollution. Try to avoid outdoor air pollution and kitchen fumes. Choose environmentally friendly decoration materials. Balance nutrition, eat more grains, vegetables and fruits. Maintain an optimistic and positive attitude towards life and improve psychological adaptability.

Secondary prevention, early diagnosis and early treatment are aimed at high-risk groups, mainly long-term smokers over 40 years old, smokers for more than 20 years, smokers under 20 years old who start smoking and smoke more than 20 cigarettes a day, people who are often exposed to coal smoke, coal tar and oil smoke, people who are exposed to excessive radiation (miners, etc.), people with chronic cough, blood in sputum and family history of lung cancer. It is best for high-risk groups to have regular comprehensive physical examinations every year, and CT examinations if conditions permit. If symptoms such as irritating cough, bloody sputum and hemoptysis occur, they should go to the hospital for treatment in time.

The tertiary prevention is rehabilitation prevention. Lung cancer patients should follow the doctor's advice and go to the hospital for regular checkups.
