Purpose: As prognosis of patients with hepatocellular carcinoma (HCC) and hypersplenism is rarely reported, this study examined prognostic factors for patients who underwent surgery for this condition.
Patients and methods: This study retrospectively analyzed prognostic factors in 181 consecutive HCC patients using univariate and multivariate analyses, as well as subgroup analyses for disease-free survival (DFS) and overall survival (OS) of two groups: one group who received splenectomies (Sp) and one group who did not (non-Sp).
Results: 1, 3, and 5 year OS rates were 88.4%, 67.1%, and 52.8%, respectively; corresponding DFS rates were 67.0%, 43.8%, and 31.6%, respectively. Age ≥55 years old, cigarette smoking, tumor size ≥5 cm, microvascular invasion, and Child-Pugh grade B (versus A) correlated significantly with OS (P<0.05). Interestingly, in patients with tumor lymph node metastasis (TNM) stage I disease, DFS of the Sp-group (median DFS, 24.1 months; n=34) was significantly lower than that of the non-Sp group (median DFS, 62.1 months; n=74), P=0.034; whereas at TNM stage II, OS of the Sp-group (median OS, 79.1 months; n=21) was significantly better than that of the non-Sp group (median OS, 23.3 months; n=30), P=0.018.
Conclusion: Hepatectomy without concomitant splenectomy can contribute to improved DFS of TNM stage I HCC patients with hypersplenism, whereas simultaneous hepatectomy and splenectomy can prolong OS for patients at TNM stage II.
