This single-center retrospective study included 126 patients with first HCC recurrence after curative hepatectomy (2018\u20132024) and aimed to explore the prognostic role of recurrence pattern, classified as low-risk (oligo-recurrence: \u22643 intrahepatic nodules, each \u22643 cm) or high-risk (multiple\/large intrahepatic, tumor in vein, or extrahepatic), for PRS. In the overall cohort, the recurrence pattern independently predicted PRS (hazard ratio 2.13, p = 0.015); the preoperative Barcelona Clinic Liver Cancer (BCLC) stage, gamma-glutamyl transferase, and total bilirubin were also independent predictors. A sensitivity analysis, including post-recurrence treatment, attenuated the hazard ratio for high-risk pattern to 1.82 (95% CI 0.93\u20133.55, p = 0.079), consistent with partial mediation. Kaplan\u2013Meier analyses suggested an association between shorter TTR and worse overall survival (OS), but this finding is descriptive because OS measured from surgery is mathematically coupled with TTR. In an exploratory subgroup analysis of patients with early-stage primary HCC (BCLC 0\/A, n = 98), the recurrence pattern showed a borderline association with PRS (p = 0.053). Late detection was associated with high-risk recurrence but did not independently affect survival. These findings highlight the prognostic value of the recurrence pattern for PRS and support the consideration of TTR as a descriptive prognostic indicator, which together may inform risk-adapted follow-up and treatment strategies.<\/jats:p>","DOI":"10.3390\/curroncol33090555","type":"journal-article","created":{"date-parts":[[2026,9,14]],"date-time":"2026-09-14T10:19:41Z","timestamp":1789381181000},"page":"555","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Prognostic
