Stage II invasive lung adenocarcinoma is relatively less serious and may have a chance of clinical cure with active treatment.
Invasive lung adenocarcinoma is a kind of malignant tumor originated from the epithelium of bronchial mucosa, and its severity is closely related to the clinical stage of the disease. Invasive lung adenocarcinoma stage 2 can be divided into stage 2a and stage 2b according to tumor size and lymph node metastasis.
Stage 2a of invasive lung adenocarcinoma: the maximum diameter of tumor lesion is 4-5cm, and there is no metastasis to lymph nodes and distant organs. It usually manifests symptoms such as fever, cough, hemoptysis, chest pain, etc. Generally, surgical resection with adjuvant chemotherapy can be taken, and some patients can be cured, with better prognosis overall.
Invasive lung adenocarcinoma stage 2b: the maximum diameter of the tumor lesion is less than 5cm, accompanied by ipsilateral hilar lymph node metastasis, without metastasis to distant organs; or the maximum diameter of the tumor lesion is 5-7cm, or it involves the chest wall, pericardium, or any part of phrenic nerve, without metastasis to lymph nodes and distant organs. Generally manifested as chest pain, dyspnea, pleural effusion and other symptoms; it is necessary to do pathological testing and genetic testing first to clarify whether the patient exists sensitive targeted drugs, and choose surgical treatment, radiotherapy, chemotherapy, targeted therapy, etc. The overall prognosis is slightly worse and the condition is more serious.
To sum up, no matter whether invasive lung adenocarcinoma is stage 2A or 2B, patients should go to specialized hospitals as early as possible, follow the diagnosis and treatment advice of specialists, standardized treatment and regular follow-up.
