Medically inoperable peripheral lung cancer treated with stereotactic body radiation therapy.

Background: Lung cancer is the most frequent cause of cancer-related death in North America. There is wide variation between patients who are medically inoperable and those managed surgically. The use of stereotactic body radiotherapy (SBRT) has narrowed the gap in survival rates between operative and non-operative management for those with early stage disease.

[Breast cancer in men].

Carcinoma of the breast is relatively uncommon in men. Represents somewhere between 0.9 to 1.

Mammary malignancy in the male.

Mammary carcinoma in the male, a relatively uncommon disease, represents about 0.9 to 1.5 percent of all breast cancers.

Long term physiologic study of thoracic duct lymph and lymphocytes in rat and man.

Techniques for study of thoracic duct lymph and lymphocyte circulations in rats and in man are presented. Radiographic observations, measurements of lymph flow, lymphocyte output, blood lymphocyte level, intra-thoracic pressures and radioactive determinations in the lymph and blood of 51Cr labelled lymphocytes, indicate that the techniques are suitable for long-term study of thoracic duct circulations under physiologic conditions.

Lymphocyte function in Hodgkin's Disease.

The immunologic deficiency of Hodgkin's disease includes skin anergy, delay in homograft rejection, negative transformation response of blood lymphocytes, and susceptibility to infections, particularly those of fungal or viral etiology (1, 3, 5). Since thymus-derived lymphocytes normally mediate these functions, a disturbance of this cell system would account for the observed immunological deficiencies in Hodgkin's disease. The majority, if not all of thymus-derived lymphocytes belong to the pool of recirculating, long-lived, small lymphocytes and an unimpeded circulation of these cells between lymph and blood is considered essential for a complete expression of their immunocompetence.
