From the Guidelines
The prognosis for this 64-year-old male with advanced liver disease and splenic marginal zone lymphoma is guarded to poor, with a life expectancy likely measured in months rather than years without significant improvement in liver function and successful lymphoma treatment. The patient has multiple concerning features including massive splenomegaly extending to the umbilicus, persistent severe neutropenia (WBC of 1), declining hemoglobin (86 from 92), elevated bilirubin (37-57), and symptoms of hepatic encephalopathy requiring lactulose therapy, as guided by the European Association for the Study of the Liver and the American Association for the Study of Liver Diseases practice guideline 1. The recent TIPS procedure for portal hypertension and the need for large-volume paracentesis (8L) indicate advanced portal hypertension, which is a complication of cirrhosis as outlined in the guidelines on the management of ascites in cirrhosis by the British Society of Gastroenterology and the British Association for the Study of the Liver 1. The fatigue, brain fog, and frequent sleeping suggest progressive disease impact on quality of life. While the newly prescribed zanubrutinib (a BTK inhibitor) may help control the lymphoma and potentially reduce spleen size, the combination of advanced liver disease with hematologic malignancy presents a challenging clinical picture. Key considerations in management include:
- Close monitoring for infection risk due to neutropenia
- Management of hepatic encephalopathy, which may include adjustments to lactulose therapy
- Surveillance for further deterioration in liver function
- Palliative care consultation to address symptom management and quality of life concerns, as the patient's condition is consistent with a poor prognosis and significant impact on quality of life, as described in the guidelines 1.

From the Research
Prognosis of Splenic Marginal Zone Lymphoma
The prognosis of Splenic Marginal Zone Lymphoma (SMZL) can be variable, depending on several factors such as the stage of the disease, the presence of symptoms, and the response to treatment.
- The patient's age (64 years old) and massively enlarged spleen are significant factors to consider in the prognosis.
- The patient's low white blood cell count (WBC) of 1, which has been decreasing over time, is also a concern.
- The patient's liver disease, with previous ascites drained 8L, and current bilirubin levels between 37-57, may also impact the prognosis.
- The patient has been prescribed zanubrutinib for the spleen and lymphoma, which may improve the prognosis.
Treatment and Management
The treatment and management of SMZL can vary depending on the stage and severity of the disease.
- According to 2, a policy of watch and wait in asymptomatic patients is recommended, while symptomatic patients may benefit from rituximab with or without chemotherapy.
- Splenectomy may also be considered in some cases, as it can help resolve cytopenia and improve overall survival, as seen in 3.
- However, the patient's recent TIPS procedure in November 2024 and current lactulose treatment may also impact the management of the disease.
Disease Progression and Survival
The disease progression and survival rates for SMZL can be variable.
- According to 3, the 5-year and 10-year progression-free survival (PFS) rates were 35% and 13%, respectively, with a median PFS of 35 months.
- The 5-year and 10-year overall survival (OS) rates were 75% and 53%, respectively, with mortality due to disease progression and histological transformation in high-grade B lymphoma in 50% of cases.
- The patient's sleep patterns, brain fog, and frequent feelings of coldness may also be related to the disease progression and overall health.
Relevant Studies
Several studies have investigated the clinical characteristics and management strategies of SMZL.
- 4 presents a case of a 65-year-old man with SMZL in the setting of noncirrhotic portal hypertension.
- 5 reports a case of a 49-year-old woman with SMZL and reviews relevant literature to provide a better recognition of this disease entity.
- 6 presents a case of a 48-year-old woman with SMZL and hepatic infiltration, highlighting the importance of considering lymphoma in patients with a history of HCV infection.
