SVCS develops in 5-10% of patients with a right-side malignant intrathoracic mass lesion. In 1969, Salsali and Cliffton observed SVCS in 4.2% of 4960 patients with lung cancer; 80% of the tumors inducing SVCS were of the right lung. [17] In five large series of small-cell lung cancer, 9-19% of patients demonstrated SVCS. In 1987, Armstrong and Perez found SVCS in 1.9% of 952 patients with lymphoma. [18]
