Lung adenocarcinoma in situ is adenocarcinoma of the lung in situ. After complete surgical resection of adenocarcinoma of the lung in situ, no other treatment is usually needed, and the disease-free survival rate can reach 100%.
Lung adenocarcinoma in situ is a non-invasive adenocarcinoma, defined as a solitary adenocarcinoma, less than or equal to 3 cm, with epithelial growth of cancer cells, confined to normal alveolar structures.
Adenocarcinoma in situ of the lung represents the absence of cancer cell infiltration and distant metastasis, and the clinical stage is defined as occult carcinoma (TisN0M0), and the disease-free survival rate after simple surgical resection is generally up to 100%.
After resection of adenocarcinoma in situ, there is no need for other treatments, such as radiotherapy, but regular review is required as prescribed by doctors.
