A 10-year experience with splenectomy in patients with malignant non-Hodgkin's lymphoma at the Norwegian Radium Hospital.
BACKGROUND
Splenectomy is a major surgical intervention that has many implications for patients with malignant non-Hodgkin's lymphoma. As debated during the last few decades, the therapeutic benefit must outweigh the surgical risk and the loss of cellular immunity. A more liberal attitude toward splenectomy developed during the years 1980-1990 at the Norwegian Radium Hospital, as illustrated by the higher number of operations performed in the last 5 years (21 patients) compared to the first 5 years (14 patients).


METHODS
A 10-year retrospective review of the effects and side effects of splenectomy in 35 patients with malignant non-Hodgkin's lymphoma was performed, based on information obtained from the patient files at the authors' institution.


RESULTS
Clinical Stage IV disease was found in 29 patients (83%), and B symptoms in 15 patients (43%). At diagnosis, 26 patients (74%) had splenomegaly, and 8 patients (23%) had primary splenic lymphoma. The surgical mortality was 2.9%, and the morbidity was 37%. Infection was the most common complication, occurring in seven patients (20%). Pneumococcal vaccination had been performed in 13 patients, and the frequency of septicemia and pneumonia tended to be higher during follow-up in unvaccinated patients (not significant). Blood counts returned to normal during the first postoperative month in 18 of 25 patients (72%) who had cytopenia. After splenectomy, a durable remission was achieved in five patients (14%) who did not receive subsequent treatment.


CONCLUSIONS
Splenectomy has the potential to relieve local symptoms, correct cytopenias, and modify the disease course in patients with malignant non-Hodgkin's lymphomas, even in advanced stages, at the cost of an acceptable operative risk.
