[Possibility of immunostimulation in patients with lung cancer. Study of lymphocyte subpopulations]

The study concerns 15 patients affected by pulmonary cancer using rosette Et, Ea, EAChu in pre-treatment phase but after leven-Therapy and Finally after surgery. After surgery we also evaluated the Ts population. The conclusions of our studies demonstrate a significant decrease of the rosette Et-Ea population in the pre-treatment phase that becomes normal after treatment and the use of surgery. Very important is the observation of the decrease of rosette Ts and said decrease coned be corolated with the presence in these subjects of inhibitory or facilitary factors which coned limit the immunitary intervention by an inhibitory action on the Ts lymphocytes.
