Does costochondritis symptom of lung cancer differ?

summary

Nowadays, the incidence rate and mortality rate of lung cancer are increasing rapidly. This is a worldwide trend. Lung cancer ranks the first among the most common male malignancies in many developed countries, accounting for two or three of the female common malignancies. About 5% ～ 10% of the patients with early lung cancer have no symptoms, which can only be found in the X-ray examination. More than 90% of the patients have symptoms, but they are not early specific symptoms. Generally speaking, there are four types. Does costochondritis symptom of lung cancer differ? Let's talk about it.

Does costochondritis symptom of lung cancer differ?

(1) Extrathoracic metastasis: lung cancer often metastasizes along lymphatic vessels and blood vessels, especially in cervical lymph nodes, liver, adrenal gland, bone, kidney and brain. Metastasis is the earliest manifestation in nearly 15% of the patients. Hematogenous metastasis is the most common in adenocarcinoma and small cell lung cancer.

(2) Extrapulmonary and intrathoracic manifestations: due to tumor invasion of pleura, chest wall, mediastinal organs and intrathoracic nerves, a series of chest manifestations can be caused. Tumor invasion of pleura can cause respiratory pain and pleural effusion (pleural effusion). Pleural effusion is bloody, indicating poor prognosis. If malignant tumor cells were found in pleural effusion, the chance of operation was lost. Mediastinal involvement is mostly caused by mediastinal lymph node metastasis, and a few are direct invasion. In 5% of the patients, the tumor compressed the superior vena cava, causing swelling of the upper limbs and above the shoulder, venous distention, headache and dyspnea, indicating that they were in advanced stage. Tumor compression of esophagus can cause dysphagia, and invasion of recurrent laryngeal nerve can cause hoarseness.

(3) Extrathoracic non metastatic manifestations: only 2% of patients with extrathoracic non metastatic manifestations can appear, but the symptoms are complex, involving more systems, and the etiological mechanism is unknown. Common skeletal manifestations, such as clubbing fingers (toes) and osteoarthropathy; Neuromuscular manifestations, such as myopathy, peripheral neuropathy, cerebellar degeneration, etc; Endocrine manifestations, such as Cushing's syndrome, abnormal hormone secretion, carcinoid syndrome, hypercalcemia, etc; Vascular manifestations, such as phlebitis, endocarditis, etc; Blood manifestations, such as anemia, purpura, leukemoid reaction, etc; Skin manifestations, such as acanthosis nigricans, scleroderma, etc.
