Surgical therapy of localized abdominal non-Hodgkin's lymphomas.

Non-Hodgkin's lymphomas may involve a variety of abdominal organs, including the liver, spleen, gastrointestinal tract, and retroperitoneum. The number of organs potentially involved and the noncontiguous mode of spread make non-Hodgkin's lymphoma a difficult tumor to evaluate at the time of laparotomy. To clarify the surgical management of patients with this tumor, we retrospectively reviewed the medical records of 202 patients with histologically proven abdominal lymphomas. Within this group, 36 patients underwent laparotomy before they had chemotherapy or radiation therapy. Ten patients were explored to establish a histologic diagnosis of lymphoma. The remaining 26 patients underwent laparotomy because of presumed benign disease. Twenty patients were found to have localized disease at laparotomy. Patients with localized disease demonstrated significantly better survival than patients with extranodal and nodal involvement (p less than 0.05). Four patients with local resection received no adjuvant therapy and were free of disease a median of 50 months after surgery.
