The main difference between stage IA adenocarcinoma of the lung and invasive adenocarcinoma of the lung IA lies in the manifestation of tumor cells and treatment modalities.
Invasive lung adenocarcinoma refers to lung cancer tumor cells breaking through the basement membrane and invading the interstitium, usually infiltrating the surrounding connective tissue and lymphocytes. Pathological examination reveals that the tumor cells of invasive lung adenocarcinoma are densely distributed and the cell shapes vary greatly.
Surgical treatment of invasive lung adenocarcinoma needs to clear the surrounding lymphatic tissues and connective tissues to avoid the spread of tumor cells.
Adherent lung adenocarcinoma refers to the growth site of tumor cells mainly located at the edge of the lung lobes, which will proliferate and spread along the alveolar wall. Adnexal lung adenocarcinoma usually does not cause direct damage to alveolar wall and does not infiltrate surrounding lymphatic and alveolar tissues. Therefore, in the surgical treatment of adenocarcinoma, surgical resection can effectively cure it.
When different types of lung adenocarcinoma attack, one should consult a doctor in time to confirm the diagnosis and choose an appropriate treatment plan under the doctor’s guidance.
