RESUMO
CONTEXT AND AIMS: The identification of inflammation-related prognostic heterogeneity in intermediate-stage hepatocellular carcinoma (HCC) can reveal more effective first-line treatments. Our study aimed to compare the intermediate-stage HCC patients' different inflammation-based scores in predicting their progression-free survival (PFS) after transarterial chemoembolization (TACE). MATERIALS AND METHODS: We analyzed retrospectively a total of 128 intermediate-stage HCC patients who received first-line TACE treatment. We used the Cox-proportional hazards modeling to identify the independent prognostic factors. We compared the inflammation-based scores abilities to predict the PFS through the time-dependent receiver operating characteristic curves and area under the curves. RESULTS: The multivariate analysis showed that tumor size and platelet-to-lymphocyte ratio (PLR) were the independent prognostic factors for PFS (P < 0.05). The PLR predicted the intermediate-stage HCC patients' PFS receiving the TACE treatment better than other inflammation-based scores (e.g., the neutrophil-to-lymphocyte ratio, the Glasgow Prognostic Score (GPS), the modified GPS, the Prognostic Index, the Prognostic Nutritional Index, the lymphocyte-to-monocyte ratio, and the systemic immune-inflammation index) (P < 0.05). An easy-to-use novel inflammation score based on tumor size - PLR-size score significantly improved the PFS prediction performance (P < 0.05). CONCLUSIONS: As a first-line treatment, TACE was not well suitable for all intermediate-stage HCC patients, while the PLR was a better inflammation-based score than others. Tumor size should be regarded as an essential variable in affecting intermediate-stage HCC patients' first-line treatment strategies.
