The present study aimed to investigate risk factors and predictive criteria for early and late recurrence of HCC after resection.METHODS: A retrospective analysis of 398 Chinese patients who received curative resection for HCC was conducted. Patients were divided into three groups: without recurrence, early recurrence and late recurrence. Prognostic factors and predictive criteria for early and late recurrence were statistically analyzed. RESULTS: The cumulative recurrence-free survival rates at1, 2, 3, 4, and 5 years were 75.5%, 58.2%, 54.1%, 40.5%, and28.7%, respectively. The distribution of the time to recurrence suggested that recurrence could be divided into early phase(before 2 years; n=164) and late phase (after 2 years; n=83)Cox’s multivariate proportional hazard model analysis revealed that multiplicity of tumors (P=0.004) and venous infiltration(P=0.002) were independent risk factors associated with early recurrence. In contrast, indocyanine green retention rate at 15minutes (P=0.007), serum albumin level (P=0.045), and HBeAg status ( =0.028) proved to be significant independent adverse prognostic factors for late recurrence. Patients with at least 1of the 2 early recurrence risk factors (multiplicity of tumors ≥2and venous infiltration) or with 2 or more late recurrence risk factors are often susceptible to recurrence (P=1.36e-4 and 1.0e-6respectively).CONCLUSIONS: Early and late recurrences correlate with different risk factors and predictive criteria. Early recurrence primarily results from intrahepatic metastases, while late recurrence may be multicentric in origin.展开更多

The risk of recurrence depends on a number of factors, related to the tumor, the patient, and the treatment, which are discussed in this review. Some of these factors are already well established, such as the histopathological characteristics of the tumor, Alpha-fetoprotein(AFP)levels, and waiting time. Other factors related to the biological behavior of the tumor and treatment should be recognized because they can be used in the refinement of the selection criteria of transplant candidates and in an attempt to reduce recurrence. This review also discusses the clinical presentation of recurrence and its prognosis, contributing to the identification of a subgroup of patients who may have better survival, if they are timely identified and treated.Development of recurrence after the first year, with AFP levels ≤ 100 ng/mL, and single site capable of locoregional therapy are associated with better survival after recurrence.展开更多

Both residual liver function and tumor extension factors should be considered. A new scoring system has recently been proposed by the Cancer of the Liver Italian Program (CLIP).CUP score was confirmed to be one of the best ways to stage patients with HCC. To our knowledge, however, the literature concerning the correlation between CLIP score and prognosis for patients with HCC after resection was not pubhshed. The aim of this study is to evaluate the recurrence and prognostic value of CLIP score for the patients with HCC after resection.METHODS: A retrospective survey was carried out in 174patients undergoing resection of HCC from January 1986 toJune 1998. Six patients who died in the hospital afteroperation and 11 patients with the recurrence of the diseasewere excluded at 1 month after hepatectomy. By the end ofJune 2001, 4 patients were lost and 153 patients with curativeresection have been followed up for at least three years.Among 153 patients, 115 developed intrahepatic recurrenceand 10 developed extrahepatic recurrence, whereas the other28 remained free of recurrence. Recurrences were classifiedinto early ( ＜ / = 3 year) and late ( ＞ 3 year) recurrence. TheCLIP score included the parameters involved in the Child-Pugh stage (0-2), plus macroscopic tumor morphology (0-2), AFP levels (0-1), and the presence or absence of portalthrombosis (0-1)o By contrast, portal vein thrombosis wasdefined as the presence of tumor emboli within vascularchannel analyzed by microscopic examination in this study.Risk factors for recurrence and prognostic factors forsurvival in each group were analyzed by the chi-square test,the Kaplan-Meier estimation and the COX proportionalhazards model respectively.RESULTS: The 1-, 3-, 5-, 7-, andl0-year disease-free survivalrates after curative resection of HCC were 57.2 %、 28.3 %、23.5 %、 18.8 % and 17.8 %, respectively. Median survivaltime was 28,16,10,4,and 5 mo for CLIP score 0,1,2,3, and 4to 5, respectively. Early and late recurrence developed in109 patients and 16 patients respectively. By the chi-squaretest, tumor size, micrusatsllite, venous invasion, tumortype (uninodular, muitinodular, massive), tumor extension( ＜ / = or ＞ 50 % of liver parenchyna replaced by tumor),TNM stage,CLIP score,and resection margin were the risk factors for early recurrence,whereas CLIP score and Child-Pugh stage were significant risk factors for late recurrence. in univariate survival analysis,Child-Pugh stages,resection margin,tumor size,microsatellite,venous invasion,tumor type,tumor extension,TNM stages,and CLIP score were associated with prognosis.The multivariale analysis by COX proportional hazards modes showed that the independent predictive factors of survival were resection margins and TNM stages. CONCLUSION:CLIP score has displayed a unique superiority in predictin the tumor early and late recurrence and prognosis in the patients with HCC after resection.展开更多
