Diagnosis and surgical treatment of primary hepatic lymphoma.

AIM

To assess the benefits and limits of surgery for primary hepatic lymphoma (PHL), and probability of survival after postoperative chemotherapy.

METHODS

A retrospective analysis was undertaken to determine the results of surgical treatment of PHL over the past 8 years. Only nine patients underwent such treatment. The detailed data of diagnosis, treatment, and prognosis were carefully studied.

RESULTS

All patients were mistaken as having α-fetoprotein-negative hepatic cancer before pathological diagnosis. The mean delay time between initial symptoms and final diagnosis was 26.8 d (range: 14-47 d). Hepatitis B virus infection was noted in 33.3% of these patients. Most of the lesions were found to be restricted to a solitary hepatic mass. The surgical procedure performed was left hepatectomy in five cases, including left lateral segmentectomy in three. Right hepatectomy was performed in three cases and combined procedures in one. One patient died on the eighth day after surgery, secondary to hepatic insufficiency. The cumulative 6-mo, 1-year, and 2-year survival rates after hepatic surgery were, respectively, 85.7%, 71.4%, and 47.6%. One patient survived for > 5 years after surgery without any signs of recurrence until latest follow-up, who received routine postoperative chemotherapy every month for 2 years and then regular follow-up. By univariate analysis, postoperative chemotherapy was a significant prognostic factor that influenced survival (P = 0.006).

CONCLUSION

PHL is a rare entity that is often misdiagnosed, and has a potential association with chronic hepatitis B infection. The prognosis is variable, with good response to early surgery combined with postoperative chemotherapy in strictly selected patients.
