Splenectomy indication emerged as a highly significant independent predictor of DFS (overall p < 0.001).
Splenectomy indication emerged as a highly significant independent predictor of DFS (overall p < 0.001).
Complete cytoreduction score showed borderline significance in univariate analysis ( p = 0.050).
However, when examined by specific indication, peritoneal implant splenectomy demonstrated a borderline association with increased mortality risk (OR = 4.505, 95% CI: 0.939–21.620, p = 0.060), though this did not reach statistical significance. Hilar invasion splenectomy showed no association with OS (OR = 0.448, 95% CI: 0.078–2.582, p = 0.369), and iatrogenic splenectomy could not be estimated due to zero events.
