  • Abstract: Abstract Background

    No guidelines exist for the management of cardiophrenic lymph nodes in patients with hepatocellular carcinoma (HCC) being evaluated for liver transplantation.

    Methods

    One hundred and seventy‐eight patients with HCC listed for liver transplant received both pre‐transplant computed tomography (CT) and follow‐up CT scans. Enlarged cardiophrenic lymph nodes on CT were characterized and followed on subsequent scans; lymph node outcomes were assigned to “reduced” and “not reduced” categories. Tumor and patient characteristics were also recorded.

    Results

    Seventy‐one of one hundred and seventy‐eight patients (39.9%) had at least one cardiophrenic lymph node larger than 8 mm in diameter on pre‐transplant CT. One hundred and sixty‐six total lymph nodes were characterized. Six lymph nodes (3.6%) in two patients increased in size on follow‐up imaging; all six cardiophrenic lymph nodes were presumed to represent metastases. There was a statistically significant reduction in lymph node size in patients who were transplanted vs. those who were not transplanted. Furthermore, a statistically significant association was found between increasing Model for End‐Stage Liver Disease score and lymph node size reduction. There were no significant differences in post‐transplant survival between patients with different lymph node outcomes.

    Conclusion

    In the absence of metastatic disease in other sites, these lymph nodes are probably reactive; further workup is likely not necessary.
