During lung cancer surgery, lymph nodes may be sampled or removed so that specialists can examine them for cancer cells.
If the relevant nodes are negative, that is generally a favorable result. It can support a conclusion that the cancer has not spread to those examined nodes.
However, lymph node findings must be interpreted alongside the tumor’s size, location, pathological features, and other staging information. A single result does not tell the entire story.
Does every patient need chemotherapy?
No. Additional treatment after surgery depends on the type and stage of cancer, the likelihood of recurrence, molecular findings where relevant, and the patient’s overall health.
Some patients with early-stage non-small cell lung cancer may be managed with surgery followed by surveillance. Others may be advised to receive additional treatment because their cancer has features associated with a higher risk of recurrence.
Depending on the case, options can include chemotherapy, immunotherapy, targeted therapy, or radiation. These treatments have different purposes and are not interchangeable.
