Whether invasive lung adenocarcinoma has metastasized can be judged according to clinical manifestations, imaging examination and pathological examination.
1. Clinical manifestations: if invasive lung adenocarcinoma has metastasized, there may be uncomfortable symptoms at the metastatic site, such as pain in the liver area if it has metastasized to the liver, bone pain if it has metastasized to the bone, headache if it has metastasized to the head, etc. However, not all metastases will cause pain. However, not all metastases will have pain, and this item can only be used as a preliminary diagnosis.
2. Imaging examination: through abdominal CT, we can know whether there is abdominal metastasis; through cranial MRI, we can know whether there is cranial brain metastasis. Through bone scan to determine whether the bone metastasis, through the lymph node ultrasound to know whether there is lymph node metastasis, etc. The best way is to carry out PET-CT, which can comprehensively understand whether there is metastasis.
3. Pathological examination: This method is the gold standard for determining whether metastasis has occurred or not. Tissues from the suspected metastatic area are taken for pathological examination, so as to clarify whether there is metastasis or not.
After clarifying the situation through the above examinations, the doctor will evaluate and formulate a corresponding treatment plan.
