Yu: A concise review of updated guidelines regarding the management of hepatocellular carcinoma around the world: 2010-2016


Many guidelines for hepatocellular carcinoma (HCC) have been published and updated globally. In contrast to other cancers, there is a range of treatment options for HCC involving several multidisciplinary care of the patient. Consequently, enormous heterogeneity in management trends has been observed. To support standard care for HCC, we systematically appraised 8 current guidelines for HCC around the world, including 3 guidelines from Asia, 2 from Europe, and 3 from the United States according to the selection criteria of credibility influence and multi-faceted. After a systematic appraisal, we found that these guidelines have both similarities and dissimilarities in terms of surveillance and treatment allocation recommendations due to regional differences in disease and other variables (diagnosis, staging systems) secondary to the lack of a solid, high level of evidence. In contrast to other tumors, the geographic differences in tumor biology (i.e., areas of increased hepatitis B prevalence) and available resources (organ availability for transplantation, medical technology, accessibility to treatment, health systems, and health resources) make it impractical to have an internationally universal guideline for all patients with HCC. Although Barcelona-Clinic Liver Cancer (BCLC) has long been dominant system for treatment-guiding staging of HCC, many Asia-pacific experts do not fully agree with its principle. The concepts of BCLC, for surgical resection or other locoregional therapy, are considered too conservative. Asian guidelines represent consensus about surgical resection and TACE indication for more advanced tumor.


Hepatocellular carcinoma (HCC) is the fifth most common malignancy and the second leading reason of cancer-associated deaths around the world, and more than 600,000 deaths are reported internationally each year [1,2]. Many global studies have examined the management of HCC [3-5]. However, the general prognosis is still poor with overall survival rates of 3-5% [6]. Following a management model, guidelines were defined as ‘systematically derived statements to assist medical practitioner and patient decisions about proper healthcare for specific medical conditions [7]’. The full application of guidelines could attain the following goals: (i) serving as a guide for proper medical decision-making by practitioners; (ii) improving the quality of healthcare and outcomes for patients and (iii) supporting and influencing local or nationwide authorities that allocate resources [8]. Many guidelines for HCC have been published globally since the European Association for the Study of the Liver (EASL) published their guidelines for HCC in 2001 [9]. In this article, we performed an English language literature search on the subject of the guidelines or consensus for HCC published and/or updated in PubMed database during the period 2010-2016. References suitable for all of the following three criteria were included: (i) Credibility, as measured by whether the guidelines were broadly cited by following guidelines or other publications about the management of HCC after the original guidelines were published; (ii) Influence, an indication that the guidelines were generated with the support of government or academic/medical societies and that the guidelines attract national attention regarding their application and the standard management for HCC and (iii) Multi-lateral, meaning that the guidelines encompassed content on the diagnosis and treatment of HCC at a minimum [7].


After screening, we adopted 9 current guidelines for HCC around the world, comprising 3 guidelines from Asia [the Korean Liver Cancer Study Group (KLCSG) and the National Cancer Center (NCC) [10]; the Japan Society of Hepatology (JSH) [11]; the Asian Pacific Association for the Study of the Liver (APASL) [12]], 2 from Europe [the European Association for the Study of the Liver (EASL) and the European Organization for Research and Treatment of Cancer (EORTC) [13]; the European Society for Medical Oncology (ESMO)-European Society of Digestive Oncology (ESDO) [14]], and 3 from the United States [American Association for the Study of Liver Disease (AASLD) [15]; National Comprehensive Cancer Network (NCCN) [16]; American College of Gastroenterology (ACG) [17]] (Table 1). The 8 current guidelines were comparatively evaluated to systematically appraise these guidelines for HCC in this article.

Surveillance strategy

Target population

Surveillance is the periodic implementation of a sensitive diagnostic test to detect early disease in a certain high-risk population such as HBV infection, HCV infection, and cirrhosis (Table 2). In their guidelines for the management of HCC, the AASLD recommends HCC screening and surveillance for the following high-risk groups: Asian male hepatitis B carriers over age 40, Asian female hepatitis B carriers over age 50, hepatitis B carriers with a family history of HCC, Africans and African Americans with hepatitis B, cirrhotic hepatitis B carriers, individuals with hepatitis C cirrhosis, individuals with stage 4 primary biliary cirrhosis, individuals with genetic hemochromatosis and cirrhosis, individuals with alpha 1-antitypsin deficiency and cirrhosis, individuals with cirrhosis from other etiologies [15].


Ultrasonography (US) has long been the radiographic methodology of choice for HCC surveillance, and a meta-analysis reported a pooled sensitivity of 94% in detecting lesions [18] and a reported specificity of >90% [19]. Serum α-fetoprotein (AFP) has been traditionally and commonly used as a tumor marker of HCC. However, serum AFP level is normal in up to 35% of cases of small HCC and can be nonspecifically raised in patients with active hepatitis or active hepatocyte regeneration. Notably, AFP has been mostly evaluated in the diagnostic setting rather than for surveillance. When combined with US, AFP levels can provide additional detection in 6-8% of cases not previously visualized by US [13]. Reasons for the suboptimal performance of AFP in the surveillance setting are dual. Firstly, fluctuating levels of AFP in cirrhotics might reflect flares of HBV or HCV infection, exacerbation of underlying liver disease or HCC development [20]. Secondly, only a small portion of tumors at an early stage (10-20%) have abnormal AFP serum levels, a fact that has been recently connected with a molecular subtype of aggressive HCCs (S2 class, EpCAM positive) [21-23]. In this context, some western guidelines (AASLD, EASL-EORTC, and ESMO-ESDO) recommend US-based surveillance and do not recommend the combination with AFP, as the 6-8% improvement in the detection rate does not offset the increase in false positive results, eventually leading to an about 80% rise in the cost of each small HCC diagnosed [18,24]. However, the panel of NCCN guideline state that AFP may have utility for enhancing detection of HCC when used in combination with US in the screening setting for at-risk individuals [16]. ACG guideline also states that diagnostic examination should be performed in cirrhotics with an elevated or rising AFP in the absence of a liver nodule on US. Most Asian guidelines recommend surveillance program based on combination of US and AFP. Furthermore, a recent JSH guideline indicates the combined use of tumor markers (AFP >200 ng/mL, AFP-L3 >15%, or DCP >40 mAU/mL) for the diagnosis of HCC [11]. Further well-designed studies are necessary to confirm their roles in the surveillance of HCC.


The ideal interval of diagnostic tools in a surveillance setting should be evaluated from the cost-effectiveness point of view because it is clear that more frequent tests can detect HCC nodules of smaller size. Except NCCN guideline (6-12 months), many guidelines have adopted an interval of 6 months based on available data on mean HCC doubling time [25-27]. Considering, though, that inter-patient variability is so enormous, a shorter 3 month interval in extremely high risk patients has been proposed by JSH [11]. However, the unique randomized study comparing 3 versus 6-month based programs failed to detect any differences [28]. On the other hand, cohort comparing 6 versus 12-month policies provide similar results [29,30], while retrospective studies showed better performance of the 6-month in terms of stage migration (small HCC amenable for curative treatments) [31] and survival [32]. Meta-analysis of prospective studies has demonstrated that the pooled sensitivity of US-based surveillance decreases from 70% with the 6-month interval to 50% with the 12-month interval [18]. Finally, cost-effectiveness studies have demonstrated that semi-annual US-based surveillance increases quality-adjusted life expectancy at a reasonable cost [33].

Recall policies

Recall policies are the policies introduced to deal with an abnormal screening test result. The tests and the interval of follow-up are different from surveillance. Recall policies cover the examinations and follow-up that determines if an abnormality detected on surveillance is or is not HCC. Recall is intimately entangled with the diagnostic process [15]. For lesions smaller than 1 cm, AASLD recommends close follow-up at 3-month intervals with the technic that first documented the existence of the nodules [15]. NCCN guideline recommends to continue imaging every 3-6 months for 2 years with technic that first detected nodule(s) returning to baseline surveillance program after 2 years of stability [16]. EASL-EORTC recommends a tight follow-up every 4 months in the same condition [13]. JSH recommends dynamic computed tomography (CT) or magnetic resonance imaging (MRI) when a nodule was detected by US regardless of size [11]. If no lesions were detected on diagnostic images, JSH recommends a follow-up every 3 months. Other guidelines do not state recall policies.


There are two types of diagnostic algorithms in the 8 guidelines: (i) Size-based diagnostic algorithms was recommended by 5 (KLCSG-NCC, JSH, EASL-EORTC, AASLD, and NCCN) of the 8 guidelines. When a nodule is identified, definitive diagnosis will be made with a nodule diameter of <1 cm, 1-2 cm and >2 cm. (ii) Non size-based diagnostic algorithms. HCC can be diagnosed with characteristic findings on dynamic CT or dynamic MRI (i.e. hypervascularity in the arterial phase and washout in the portal venous or delayed phase) regardless of tumor size, as recommended by 3 (APASL and ESMO-ESDO, and ACG) of the 8 guidelines.

Non-invasive diagnosis

Most guidelines, at present, recommend four-phase multidetector computed tomography (MDCT) or contrast-enhanced dynamic MRI using extracellular contrast agents as the primary examination for the diagnosis of HCCs in cirrhotics. The diagnostic criteria endorsed by most guidelines focus mainly on imaging characteristics in common-for example, arterial phase hypervascularity and venous or delayed phase wash-out [34]. However, despite the similarities in the diagnostic criteria of HCC, there are some disagreements among the guidelines. These include the use of tumor markers such as AFP, lesion size/growth, inclusion of sub-centimeter nodules, the number of required imaging modalities, and the use of contrast-enhanced ultrasonography (CEUS) and/or tissue-specific MRI contrast media [35]. As an example, many western guidelines recommend biopsy if a nodule between 1 and 2 cm does not show typical imaging features of HCC. Conversely, the APASL and JSH guidelines include liver-specific contrast media enhanced MRI, such as superparamagnetic iron oxide or gadoxetic acid (Primovist; Bayer Healthcare, Berlin, Germany), or CEUS as well as biopsy when initial diagnostic tests show atypical imaging features of the lesion.
The diagnostic criteria of the new KLCSG-NCC guidelines in 2014 present several differences compared with the criteria of other guidelines [10]. In the new KLCSG-NCC guidelines, a noninvasive imaging diagnosis of HCC can be made for sub-centimeter nodules in case of the typical findings of HCC in ≥ 2 imaging modalities; with increased serum AFP levels with a rising tendency over time in patients with suppressed hepatitis activity [10]. According to western guidelines including the EASL-EORTC, the AASLD, and NCCN, noninvasive diagnosis may be applicable only for nodules >1 cm in cirrhotics, whereas Asian guidelines including the APASL and the JSH also allow the noninvasive diagnosis of subcentimeter nodules based on the hallmark imaging features of HCC in patients with chronic liver disease or liver cirrhosis. This difference could be attributed to the difference in the prevalence of HCC across regions as well as in the policy for liver transplantation allocation. Therefore, the noninvasive diagnostic criteria of HCC proposed by western guidelines including the EASL-EORTC, the AASLD, and NCCN were intentionally not optimized to attain maximum sensitivity for HCC detection, but rather to increase the specificity of an HCC diagnosis [13,15,16,36]. The new KLCSG-NCC and JSH guidelines include gadoxetic acid-enhanced MRI as well as dynamic CT or MRI with extracellular contrast media as primary diagnostic tests for the noninvasive diagnosis of HCC. However, it is not yet used as a primary diagnostic test for the noninvasive diagnosis of HCC in the other guidelines. This difference in the respective guidelines may have been caused by the preference toward higher sensitivities and specificities of the imaging modalities for HCC [34]. There is concern that although gadoxetic acid could contribute to increased sensitivity, this could be at a cost of losing specificity [34]. In addition, APASL, JSH, and NCCN guidelines used CEUS as a secondary diagnostic test, but it was not included in the other guidelines including the new KLCSG-NCC guidelines because the role of it is still controversial [13].

Pathological diagnosis

Pathological diagnosis is recommended by all 8 guidelines if imaging diagnosis does not disclose characteristic features of HCC. In terms of the policy for indeterminate nodules not fulfilling specific imaging criteria, the new KLCSG-NCC guidelines recommend either biopsy or follow-up with imaging if percutaneous biopsy is not feasible for liver nodules in high-risk patients. On the contrary, the AASLD and the EASL-EORTC guidelines recommend that all US-visible nodules > 1 cm not satisfying HCC diagnostic criteria should be evaluated either by biopsy or a second exam and, if the second exam is also non-diagnostic, be biopsied. Until now, no outcome studies have been performed to show that survival is prolonged by a biopsy of indeterminate nodules >1 cm rather than meticulous follow-up for growth [37].
Regular surveillance and non-invasive diagnostic criteria of current guidelines are summarized in Table 2.


Assessment of tumor extension is crucial for defining staging and treatment strategy. Pre-operative staging prior to liver transplantation should include abdominal dynamic CT or MRI, chest CT and bone scan [13]. PET based imaging is not accurate to stage early tumors.
The Barcelona-Clinic Liver Cancer (BCLC) staging system has appeared as the most popular to guide treatment decision and has been endorsed by many guidelines including AASLD, EASL-EORTC, and ESMO-ESDO [with two modifications: (i) Portal hypertension is omitted from the algorithm and gives more freedom in the clinical decision for resection. (ii) Patients with poor liver function (Child-Pugh C) and tumor extent within the Milan criteria should, in our opinion, not be deprived of the possibility of liver transplantation and are therefore not classified as terminal stage]. BCLC is based on the analysis of independent studies in different clinical situations. It includes prognostic factors related to tumor status, hepatic functional status, and performance status, together with treatment-dependent factors obtained from cohort studies and randomized clinical trials. The system links tumor stage with the treatment plan allowing an assessment of life expectancy related to specific HCC management [13]. However, other trials have shown conflicting results thus preferring other staging systems [38-41]. There are many limitations for the BCLC system (Table 3) [42]. Furthermore, the BCLC system was not developed from a cohort of HCC patients by a multivariate analysis, and therefore it is not a prognostication system able to predict the mortality of HCC patients [43]. Moreover, the use of the BCLC staging system is limited because it has a subjective component (i.e., performance status) and rough evaluation of hepatic function (i.e., Child-Pugh class) [10]. The main limitation of the BCLC is its rigidity for acting as a treatment algorithm [10,43]. The KLCSG-NCC have adopted the fifth version of the modified International Union for Cancer Control (UICC) staging system as a primary staging system for HCC (Table 4) [44]. The mUICC staging system appears more advantageous for assessing the prognosis of small HCC because it sets the size cut-off to 2 cm unlike the American Joint Committee on Cancer (AJCC)/UICC, which used a cut-off of 5 cm [10]. However, the fifth version of the mUICC has limitations, particular its paucity of extensive validation and different criteria compared with the current seventh AJCC/UICC TNM staging system. Therefore, the KLCSG-NCC accepted the mUICC stages as a primary staging system and the BCLC system as a complementary system. The NCCN does not adopt a specific staging system. Instead, it classifies the patient’s disease as operable, unresectable, or inoperable according to performance status and comorbidity. Classification is also based on local versus metastatic disease [16,45]. JSH does not accept a particular staging system but it classifies the patient’s disease according to three factors: (i) degree of hepatic damage (Child-Pugh A, B versus C); (ii) tumor numbers (1 versus 2 or 3 versus ≥ 4); and (iii) tumor diameter (≤ 3 cm versus > 3 cm) [11]. Neither BCLC nor any other staging systems has been universally endorsed, as pointed out by the AASLD guidelines [15], meaning that global consensus on the use of any certain model is lacking.


Although BCLC has long been dominant system for treatment-guiding staging of HCC, many Asia-pacific experts do not fully agree with its principle. The concepts of BCLC, for surgical resection or other locoregional therapy, are considered too conservative. Asian guidelines including the KLCSG-NCC, the APASL, and JSH represent consensus about surgical resection and TACE indication for more advanced tumor (Fig. 1). Comparisons of the basic principles of these different guidelines will be addressed.

Resection & transplantation

The choice of treatment for HCC depends mainly on the extent of disease [7]. In general, a resection should be the first option for non-cirrhotic patients with local lesions, a liver transplantation (LT) should be the first option for patients with decompensated cirrhosis (Child-Pugh C), and advances in the application of nonsurgical therapies, such as radiofrequency ablation (RFA), percutaneous ethanol injection therapy (PEIT), and transarterial chemoembolization (TACE), should also be integrated in the management of HCC. The 8 guidelines do differ about appropriate candidates for surgery. For example, according to the guidelines endorsing BCLC staging system, appropriate candidates for a resection are patients with a solitary tumor without the evidence of portal hypertension. In contrast, the KLCSG-NCC states that HCC resection can be considered in patients with ≤ 3 intrahepatic tumors without macrovascular invasion if liver function is well preserved (Fig. 1) [10]. JSH guideline also recommends that a resection should be performed for patients with Child-Pugh A/B and ≤ 3 tumors regardless of tumor size [11]. A resection has been found to be most beneficial for single tumors in patients without cirrhosis, with post-resection 5-year survival rates of 41-74% [46-48]. For cirrhotics with local lesions and good liver function (Child-Pugh A), the choice of a resection or a LT is a subject of discussion. Western guidelines [13] recommends a LT as the first approach because resections are performed a second time more often than LT. A resection may have to be performed again in 50% of cases at 3 years and 70% at 5 years [49,50]; a LT may have to be performed again for patients within the Milan criteria in approximately 10% of cases and the 5-year survival rate for such patients is 70-80% [51,52]. In contrast, the JSH recommends a resection as the first approach in these cases [11].
Down-staging (e.g., with TACE) can be considered for HCCs exceeding the criteria for LT in the KLCSG-NCC and NCCN guidelines [10,16], but other guidelines do not admit down-staging. In the KLCSG-NCC and NCCN guidelines, an expanded indication for LT beyond the Milan criteria can be considered in HCC cases without definitive vascular invasion or extrahepatic spread, if other effective therapeutic options are not inapplicable [10,16]. However, other guidelines do not admit an expanded indication for LT. EASL-EORTC only admits modest expansion of the Milan criteria applying the “up-to-seven” in patients without microvascular invasion [13].

Loco-regional therapies

Local ablation therapy is another choice for patients with a solitary tumor or up to 3 tumors ≤ 3 cm each and good hepatic function (Child-Pugh A/B) whereas a LT is recommended for patients age 65 years or younger with poor hepatic function (Child-Pugh C) and a solitary tumor ≤ 5 cm or up to 3 tumors ≤ 3 cm [11]. In the KLCSG-NCC and NCCN guidelines, survival outcomes can be improved by combining RFA and TACE compared to RFA alone in patients with intermediate-sized HCCs (i.e., 3-5 cm) if resection is unfeasible [10,16]. NCCN guideline states that all tumors irrespective of location may be amenable to transarterial therapies provided that the arterial blood supply to the tumor may be isolated without excessive non-target treatment [16]. Moreover, the KLCSG-NCC guideline recommends TACE for patients with good performance status without macrovascular invasion or extrahepatic spread who are ineligible for curative treatments including surgical resection, LT, RFA, or PEIT [10]. As Figure 1 shows, the KLCSG-NCC guideline permits the broadest indications for TACE than other guidelines.

Systemic therapies

In recent years, sorafenib has been approved for the treatment of patients with unresectable HCC by the European Medicines Evaluation Agency and the U.S. Food and Drug Administration in 2007. The efficacy of sorafenib in advanced HCC has resulted in an overall decrease in mortality of 31%, with a median survival of 10.7 months for sorafenib group versus 7.9 months for placebo group [53,54]. Although sorafenib was recommended for the treatment of advanced patients by 8 guidelines, this is not routinely followed by clinicians, because the expected survival benefits are modest over placebo considering its high cost [55]. As Figure 1 shows, there are several options beside sorafenib. A recent Korean study reports that the median survival rate of TACE-treated HCC invading the major portal vein is 22-30 months for a subgroup of patients with nodular tumor growth or limited tumor extent [56,57]. A recent prospective nonrandomized study on unresectable HCC invading portal vein shows more favorable survival outcomes for the TACE-treated group than the supportive care group [58]. Therefore, in case of portal vein invasion, Asian guidelines state that TACE can be considered for patients with localized tumors and well-preserved liver function [10-12]. Systemic or selective intra-arterial chemotherapy is not recommended in most western guidelines, but NCCN guideline and Asian guidelines permit cytotoxic chemotherapy especially in patients with advanced tumors who have well-preserved hepatic function and good performance status in whom sorafenib therapy has failed [10-12,16].


Most western guidelines and even Asian guidelines do not recommend external-beam radiation therapy (EBRT) for the treatment of intrahepatic HCC. However, NCCN and the KLCSG-NCC guideline recommend EBRT as an initial treatment option for intrahepatic HCC [10,16]. EBRT can be performed in HCC patients with good hepatic functions (Child-Pugh class A or superb B) and the irradiated (≥ 30 Gy) total liver volume is ≤ 60 % [10,59]. EBRT can be considered for HCC patients ineligible for resection, LT, RFA, PEIT, or TACE; show incomplete response to TACE; with portal vein invasion when the dose-volume criteria are met; and to alleviate symptoms (Fig. 1) [10].
Hopefully, some of these efforts will yield positive outcomes and increase the therapeutic options for patients with HCC.

Post-treatment follow-up

The KLCSG-NCC guideline recommends regular follow-up in patients with complete response after management with imaging studies and serum tumor markers every 2 to 6 months in the first 2 years; thereafter, regular checkups at individualized intervals [10]. AASLD guideline recommends 3 to 4 month imaging interval after initial treatment up to 2 years; thereafter, the interval can be at less frequent intervals [15]. In the follow-up strategy after resection or loco-regional therapies, EASL-EORTC recommends 3 to 4 month imaging interval [13]. NCCN guideline recommends regular follow-up in patients with complete response after treatment with imaging studies and serum AFP every 3 to 6 months for 2 years; then every 6 to 12 months [16]. After curative treatment, JSH recommends 3 to 4 month interval follow-up according to the surveillance approaches used in extremely high-risk cases at the time of onset [11].


Current guidelines by and large are similar, with some discrepancies in surveillance and treatment allocation recommendations because of regional differences in disease and other diversities (diagnosis and staging systems) secondary to a lack of solid, high-level evidence. In contrast to other malignancies, the geographic variances in tumor biology and resources make it unfeasible to have a universally accepted guideline for all HCC patients around the world. Recommendations from the 3 groups (Asia, Europe, and USA) are influenced by geographic differences in the prevalence and biology of the disease (i.e., areas of increased hepatitis B prevalence) and available resources (organ availability for LT, finances, and accessibility to treatment). It is important for both physicians and policy makers to include these considerations when treating patients with HCC as well when structuring policies and guidelines.
