What are the detailed diagnostic criteria for small cell lung cancer?

What are the detailed diagnostic criteria for small cell lung cancer? Small cell lung cancer is a less common disease. Usually, only large hospitals can diagnose this disease. Some patients go to some informal clinics for examinations to save money, but they are misdiagnosed and delay treatment. Today, we will tell you what are the detailed diagnostic criteria for small cell lung cancer?

The clinical manifestations of small cell lung cancer vary depending on the location, size, type, invasion or compression of adjacent organs, and metastasis of the primary tumor. Common clinical manifestations include the following:

(1) Local and systemic symptoms caused by tumors: such as cough, blood in sputum, chest tightness, chest pain, shortness of breath, fever, lack of appetite, weight loss, cachexia in the late stage, etc.

(ii) Symptoms of tumor invasion and metastasis: superior vena cava obstruction syndrome, Horner's syndrome, Pankow's syndrome, involvement of the recurrent laryngeal nerve causing hoarseness, headache, vomiting, hemiplegia due to brain metastasis; persistent pain in the corresponding part caused by bone metastasis, etc.

(III) Associated symptoms of lung cancer: pulmonary hypertrophic osteoarthropathy, carcinoid syndrome, and gynecomastia

The clinical features of small cell lung cancer (SCLC) are basically the same as those of non-small cell lung cancer, but its clinical course and natural history of the disease are significantly faster than those of non-small cell lung cancer, and many patients develop distant metastases in the early stages of the disease.

From the above description, we can see that the symptoms of lung cancer are not specific and are similar to the clinical manifestations of many respiratory diseases. Therefore, the key to diagnosing lung cancer based on symptoms is vigilance against lung cancer. If respiratory symptoms persist for more than two weeks without treatment, we should be highly vigilant about the possibility of lung cancer.

The diagnosis of lung cancer is the premise of treatment. The correct treatment plan and good treatment effect depend on the early detection, early diagnosis and early treatment of lung cancer. The process of lung cancer diagnosis should include general survey, medical history, physical examination, laboratory tests and special examinations, as well as lung cancer staging.
