Primary gastric lymphoma: role of computed tomography.

ABSTRACT

Computed tomography (CT) has been suggested as an alternative to surgery for predicting the stage and resectability of primary gastric lymphoma. It is our policy to perform CT scan on all patients and the decision to explore is based upon CT findings. We reviewed our experience to see if any changes were warranted. 12 patients with primary gastric lymphoma underwent CT scanning. The CT findings were compared with the pathological findings available for 10 patients. CT correctly staged 90 per cent of the patients and it obviated unnecessary exploratory surgery in 42 per cent of the patients. It permitted the planning of non-excisional therapy in 75 per cent of the patients and was useful as an indicator of response to therapy and as a follow up measure.
