Abstract
BACKGROUND

A significant number of patients with liver cirrhosis concomitantly develop some type of solid or hematological cancer, including lymphoma. Treatment of patients with lymphoma and cirrhosis is challenging for physicians due to the clinical characteristics related to cirrhosis, including biochemical and functional abnormalities, as well as portal hypertension and lack of scientific evidence, limiting the use of chemotherapy. Currently, experts recommend only offering oncological treatment to patients with compensated cirrhosis.

AIM

To evaluate the clinical characteristics and treatment outcomes in patients with cirrhosis and lymphoma treated with chemotherapy.

METHODS

This was a case-control study conducted at a tertiary care center in Mexico. Data was recorded from medical files and from 8658 possible candidates with cirrhosis and/or lymphoma (2000 to 2018). Only 23 cases had both diseases concomitantly; 10 patients with cirrhosis and lymphoma (cases) met the selection criteria and were included, and 20 patients with lymphoma (controls) were included and matched according to age, sex, and date of diagnosis, type and clinical stage of lymphoma. All patients received treatment with chemotherapy. For statistical analysis, descriptive statistics, Shapiro-Wilk test, Mann-Whitney U test, chi-square test and Fisher's exact test were used. Survival was evaluated using Kaplan-Meier curves and Log-rank test.

RESULTS

There were differences in biochemical variables inherent to liver disease and portal hypertension in patients with cirrhosis. The most frequent etiology of cirrhosis was hepatitis C virus (50%); 80% were decompensated, the median Child-Turcotte-Pugh score was 7.5 (6.75-9.25), and mean Model for End-stage Liver Disease was 11.5 ± 4.50. Regarding lymphomas, non-Hodgkin's were the most common (90%), and diffuse large B cell subtype was the most frequent, with a higher International Prognostic Index in the cases (3 vs 2, P = 0.049). The chemotherapy regimens had to be adjusted more frequently in the case group (50% vs 5%, P = 0.009). The complications derived from chemotherapy were similar between both groups (80% vs 90%, P = 0.407); however, non-hematological toxicities were more common in the case group (30% vs 0%, P = 0.030). There was no difference in the response to treatment between groups. Survival was higher in the control group (56 wk vs 30 wk, P = 0.269), although it was not statistically significant.

CONCLUSION

It may be possible to administer chemotherapy in selected cirrhotic patients, regardless of their severity, obtaining satisfactory clinical outcomes. Prospective clinical trials are needed to generate stronger recommendations.

Core tip: Treatment in patients with liver cirrhosis and lymphoma represents a challenge for physicians given the lack of scientific evidence. Experts recommend offering oncological treatment only to patients with compensated cirrhosis. In this study, we included mainly decompensated patients with cirrhosis and lymphoma, and when compared to patients with lymphoma, we observed that clinical characteristics, response rate and complications derived from chemotherapy were similar in both groups. Chemotherapy was adjusted more in patients with liver dysfunction; however, this did not alter the response to treatment or prognosis. We propose that lymphoma treatment can be provided in patients with cirrhosis at any clinical state.
