First, you need to know the stage (as you mentioned your uncle has
adenocarcinoma which belongs to non-small cell lung cancer. If is small cell
lung cancer, it will be a different story). For most of stage I and II,
even some IIIA, the intent for treatment is cure.
If your uncle's lung cancer is just 2.5 cm and no metastases, then his
cancer is stage IA. This stage can be cured with surgery only, followed by
imagine surveillance. But he does not need an abdominal ultrasound for this
purpose.
If the cancer is over 3 cm, without metastases, it will be stage Ib. Some
local invasion will be also considered as Ib or II. In addition to surgery,
chemotherapy is usually used for stage II; for Ib it is debatable.
For stage III, depending on where the lymph nodes are involved. It could be
treated with surgery, chemotherapy and radiation therapy. The use of those
treatment depends on the oncologist's knowledge, experience and the
resources available.
If the cancer spread distally, or metastasizes to the other side of lungs,
it is unresectable. Surgery will not be used in this setting. Without
treatment, those patients usually live 3-4 months. With palliative
chemotherapy, we can prolong the survival up to one year in general.
However, recent advances in adenocarcinoma of lungs provided very solid data
to improve the progression free survival and overall survival, particularly
in Asian patients, female, and no history of smoking. We can look at some
gene mutations, then use targeted medicines towarding those mutated genes
treat cancer. Some patients could live for years with stable disease.
Most recently, clinical trials with immunoadaptive therapy give us very
promising data. I believe the paper will be published in the next several
months in New England Journal of Medicine.
Hope the above information helps.
