It was estimated that
there were over 172,000 new cases of lung cancer diagnosed in the United
States in 2005 and that 163,000 patients died from this group of diseases. Non-small
cell lung cancer and small cell lung cancer are the 2 types of cancer
that commonly arise from lung tissue. Almost 90% of all lung
cancers are the non-small cell lung cancer type (NSCLC) group. Within
the larger group of NSCLC disease, there are multiple types of non-small
cell lung cancer. Each type of non-small lung cancer has different
kind of cancer cells. The cancer cells of each type grow and
spread in different ways. NSCLC develops primarily as one of
the following types: Adenocarcinoma (~47%); Squamous cell carcinoma
(~35%); Large cell carcinoma (~18%). The likelihood of recovery
and the available treatment options may be determined by: 1) Whether
the cancer has spread beyond the site of the original tumor, either
within the lung or to other parts of the body; 2) Tumor size; 3) The
specific type of lung cancer; 4) The extent of patient symptoms; and
5) The overall medical condition of the patient. NSCLC is a very
serious disease and, despite recent progress, current treatments are
rarely able to provide a cure.

Cancer Society website. Additional information about clinical
trials for treatment of lung cancer can be found at the National
Cancer Institute.
