2. Non-small-cell lung cancer - Wikipedia

   en.wikipedia.org/wiki/Non-small-cell_lung_cancer

   Non-small cell lung cancer (NSCLC) cells expressing programmed death-ligand 1 (PD-L1) could interact with programmed death receptor 1 (PD-1) expressed on the surface of T cells, and result in decreased tumor cell kill by the immune system. Atezolizumab is an anti PD-L1 monoclonal antibody.

3. Lung cancer - Wikipedia

   en.wikipedia.org/wiki/Lung_cancer

   There are two main types of lung cancer, categorized by the size and appearance of the malignant cells seen by a histopathologist under a microscope: small cell lung cancer (SCLC; 15% of cases) and non-small-cell lung cancer (NSCLC; 85% of cases). [18] SCLC tumors are often found near the center of the lungs, in the major airways. [19]

4. Adenocarcinoma of the lung - Wikipedia

   en.wikipedia.org/wiki/Adenocarcinoma_of_the_lung

   Adenocarcinoma is a non-small cell lung carcinoma, and it is not as responsive to radiation therapy compared to small cell lung carcinoma. [10] However, radiotherapy may be used as an adjuvant therapy for patients who have undergone a resection surgery to reduce the risk of lung cancer relapse.

5. Pancoast tumor - Wikipedia

   en.wikipedia.org/wiki/Pancoast_tumor

   Pancoast tumors are staged similarly to most other non-small cell lung cancers using the tumor, node, and metastasis (TNM system) as well as numbers (1-4) to indicate severity. [12] At time of diagnosis, due to difficulty of early detection through imaging, most Pancoast tumors are usually staged at level T3 or T4 due to their invasion of the ...

6. Squamous-cell carcinoma of the lung - Wikipedia

   en.wikipedia.org/wiki/Squamous-cell_carcinoma_of...

   Squamous-cell carcinoma (SCC) of the lung is a histologic type of non-small-cell lung carcinoma (NSCLC). It is the second most prevalent type of lung cancer after lung adenocarcinoma and it originates in the bronchi. Its tumor cells are characterized by a squamous appearance, similar to the one observed in epidermal cells.

7. Small-cell carcinoma - Wikipedia

   en.wikipedia.org/wiki/Small-cell_carcinoma

   Small-cell lung carcinoma (SCLC) has long been divided into two clinicopathological stages, termed limited stage (LS) and extensive stage (ES). [8] The stage is generally determined by the presence or absence of metastases, whether or not the tumor appears limited to the thorax, and whether or not the entire tumor burden within the chest can feasibly be encompassed within a single radiotherapy ...
