Curability of gastrointestinal lymphoma with combined surgery and radiation

Of a total of 1394 patients with non-Hodgkin's lymphomas seen at the Princess Margaret Hospital between January 1, 1967 and December 31, 1978, 150 presented with gastrointestinal involvement. One hundred-thirteen of those patients had localized (Stage I & II) disease. Prognostic factors affecting outcome included hulk of residual disease after initial surgery and presence of B-symptoms. Patients with Stage IA and IIA with gross residual lysphoma less than $\text{2}\text{1}\text{2}$ em in diameter treated with post-operative abdominal irradiation achieved 85% 10 years failure-free rate and 88% 10 year actuarial cause specific survival. The above group is considered curable with surgery and low dose adjuvant radiation.
