[Tuberculin sensitization in patients with lung cancer].

The data on immunological and morphological examinations of 85 lung cancer patients have been compared. Tuberculin sensitization indexes were shown to indicate the strength of antitumor immunity. Relationships between indexes of humoral and cellular immunologic response to tuberculin, on the one hand, and their actual levels in lung cancer patients, on the other, serve as fairly reliable indications of histological pattern of tumor and its extension.
