Site of recurrence in patients with stages I and II carcinoma of the lung resected for cure.

Ninety-nine patients with Stage I or II lung carcinoma that was other than the small cell type and who survived for more than 30 days after a "curative" resection were followed for five years or until death if it occurred prior to the five-year anniversary. Recurrent disease developed in 44 patients. Clinical data and data from postmortem examination were reviewed in these 44 patients in an attempt to classify each recurrence as either initially local or distinct metastatic disease. The site of the first documented recurrence was local in 18 patients and distance metastases in 26. When the patients with recurrence were separated into TNM categories, it was apparent that in those patients without lymph nodes metastases demonstrated in the resected specimen (N0), the initial recurrence tended to be a distant metastases, whereas in those with such involvement (N1), the initial occurrence was more often local. In light of these data, selection of appropriate initial adjuvant therapeutic modalities may be different for each type of patient.

Mast cells from human respiratory tissue and their in vitro reactivity.

Human respiratory mast cells, which were obtained coincidentally with diagnostic bronchial brush biopsy, were maintained under conditions for short-term tissue culture. Most mast cells were viable and degranulated on exposure to antibody to immunoglobulin E or to the mast cell degranulating agent compound 48-80. The degranulation of human mast cells is characteristically an intracellular process with no extracellular extrusion of granules.
