The standard management of stage IV lung cancer is palliative chemotherapy with platinum-based combination chemotherapy . However, there are some reports of patients with lung cancer with only a malignant pleural effusion and no other metastatic sites that have long-term cures with chemotherapy and surgery.[2,3] In view of the excellent performance status of the patient and the PET-CT showing no other sites of metastases, it was decided that therapy with potentially curative intent could be attempted even though this would be a deviation from established guidelines. A staging workup was performed.
What is the role of cytology in lung cancer?
Conventional cytologies such as sputum examination, bronchial lavage, bronchial brushings, fine-needle aspiration biopsy have played an important role in the diagnosis of primary and metastatic lung cancers. Immunohistochemical stains can be applied on cytological material.

Pathological complete response is defined as fibrosis or fibro inflammation without microscopic evidence of carcinoma and histologically negative nodes. Non-pCR is defined as any evidence of viable carcinoma, either at the primary site or at the resected regional LN. Those patients who achieve complete pathological response have long-term survival advantage. Junker et al.[9] found that in NSCLC patients, not only complete responders but also extensive responders with <10% residual tumor also had good long-term survival.

How to treat lung cancer?
Cancer that is limited in the lungs and has only spread to one other site (such as the brain) is not common, but it can sometimes be treated (and even potentially cured) with surgery and/or radiation therapy to treat the area of cancer spread, followed by treatment of the cancer in the lung. For example, a single tumor in the brain may be treated with surgery or stereotactic radiation, or surgery followed by radiation to the whole brain. Treatment for the lung tumor is then based on its T and N stages, and may include surgery, chemo, radiation, or some of these in combination.
Why is adjuvant chemo recommended after surgery?
Even if positive margins are not found, adjuvant chemo is usually recommended after surgery to try to destroy any cancer cells that might have been left behind. As with stage I cancers, newer lab tests now being studied may help doctors find out which patients need this adjuvant treatment and which are less likely to benefit from it.

(2) Overall two thirds of lung cancer patients have some expression of PD-L1, and one third are “high expressers” meaning over 50% of the tested tumor expresses PD-1.
What is PD-1 and PD-L1?
PD-1 and PD-L1 are proteins that inhibit certain types of immune responses, allowing cancer cells to evade detection and attack by certain immune cells in the body. Checkpoint inhibitors block the PD-1 and PD-L1 pathway and enhance the ability of the immune system to fight cancer.
Why do we do a liquid biopsy for NSCLC?
A liquid biopsy should be performed upon initial evaluation of NSCLC because it may better help identify treatable mutations than tissue biopsy alone. Initial treatment of NSCLC in individuals with an identified genomic cancer driving mutation that can be targeted is with a precision cancer medicine.
