Stage III tumors without invasion
N2 and N3 disease
This chart maps the treatment for stage III (N2 or N3)
tumors without invasion. Cancer that has spread to the
mediastinal lymph nodes is scored N2. Cancer spread to
the lymph nodes near the lung without the primary tumor
or to the supraclavicular or scalene nodes is scored N3.
N2 disease may be found only after surgery for stage I,
II, or III (T3, N1) cancer. In this case, adjuvant treatment
is based on the surgical results. If the surgical margins
are cancer-free, chemotherapy followed by radiation
therapy is recommended. If the margins have cancer,
treatment options are based on whether the cancer
can’t be seen with the naked eye (microscopic) or can
be seen (macroscopic). Microscopic cancer is found
with a microscope. For cancer not seen by the naked
eye, chemotherapy may be given at the same time
as radiation (concurrent) or beforehand (sequential).
Concurrent chemoradiation is the option for cancer that
can be seen with the naked eye.
