. Introduction

Hepatocellular carcinoma (HCC) is a major worldwide healthroblem and occurs primarily in patients with underlying cirrho-is. Thus, two separate and potentially lethal diseases, cancer andirrhosis, usually coexist in patients with HCC. Both the tumour bur-en and the underlying liver dysfunction have a negative effect onrognosis and are determinant regarding treatment. Accordingly,hen selecting a treatment for HCC, it is mandatory to consider not

nly the tumour burden but also liver function, and, in fact, tumourtaging systems for HCC include both components (i.e. integratedtaging systems).

Cirrhotic liver function is most commonly categorised accord-ng to the Child-Pugh-Turcotte score (CPT) [1] which has a strongrognostic value for HCC patients [2] and is included in all inte-rated HCC staging systems [2–5]. The Barcelona Clinic Liver Cancer

Patients with well-preserved liver function (CPT-A) are consid-ered suitable for virtually all treatment modalities, and are easilyand rigorously treated according to the BCLC stage [5], even in theintermediate (BCLC-B) stage. Patients with severely compromisedliver function (CPT-C) are instead considered terminal patients [5],suitable only for palliative care (if not transplantable) and, as such,are managed in nearly all instances following the guidelines. Con-cerning the CPT-B class, it corresponds to an intermediate, partiallycompromised situation, in between well preserved and termi-nal condition and accordingly these patients have a fragile liverfunction. The CPT classification includes different degrees of liverdysfunction with 16 different scores ranging from 5 (best function)to 15 (worst function), categorised into three classes: A–C. Specif-ically, class B includes CPT-B7, -B8 and -B9 which are, however,considered as only one single group by the BCLC staging system.Depending on the tumour burden and/or the performance status,CPT-B patients can fall into various BCLC stages [5].

hemoembolization (TACE) is the recommended treatment foratients in the BCLC-B tumour stage but evidence of the beneficial

mpact of TACE in CPT-B patients is lacking; the risk of ischaemicnsult to the liver following TACE led the authors of the guide-ines to advise against this treatment in Child-Pugh B patients, evenhough this exclusion cannot be found in the flowchart summaris-ng the treatment algorithm according to the BCLC stage [6,7]. Inact, the flowchart combines prognostic staging and treatment allo-ation, and is not as detailed as the text with an underlying risk forisinterpretation. In fact, from a prognostic point of view, BCLC-B

atients are grouped together regardless of whether they are Child-ugh A or B (thus, the flowchart is complete and correct). However,hen considering treatment, the text of the guidelines specifies

hat Child-Pugh A and B should be kept separate, as is mentionedn page 1226 [6] despite the fact that this different allocation is noteported in the flowchart and no additional information is given inhe legend of the chart in Fig. 2 of that article [6].

A retrospective investigation of treatments and outcomes ofPT-B patients (in particular, for those in the BCLC-B stage) with

primary diagnosis of HCC was carried out.The primary aims were to understand how often the guide-

ines could be followed in CPT-B patients and to identify possibleredictors of survival within this specific population of patients.his was attempted by reporting the field-practice treatments ofPT-B patients in various BCLC stages (in particular, in the BCLC-Btage), assessing CPT-B patient survival in various BCLC stages (alsoccording to the CPT specific numeric score) and investigating theresence of predictors of survival for CPT-B patients in the BCLC-Btage and for patients treated with TACE within the BCLC-B stage.

The secondary aim was to identify the predictors of eligibility forurative treatment or TACE for CPT-B patients in the BCLC-B stage

. Materials and methods

.1. Study design and patient population

From March 2001 to December 2007, 286 consecutive patientsith a primary diagnosis of HCC associated with cirrhosis were

bserved, and all data were collected at the time of observation. Thenrolment was closed in December 2007. Patients were followedp from enrolment until death or closure of the study in December011. This cut off date for enrolment allowed to have the full sur-ival history of almost all patients and was also set for consistencyecause Sorafenib was not available until then. The diagnosis of HCCas made following the most recent European Association for the

tudy of the Liver (EASL) and American Association for the Study ofiver Diseases (AASLD) guidelines [6,7]. Only patients in Child-Pughlass B liver function [1] at the time of HCC treatment were retro-pectively included in the present study. Given the retrospective

iver Cancer; CPT, Child-Pugh-Turcotte; RFA, radiofrequency ablation; and TACE,

design of the study, the Institutional Review Board, which approvedthe protocol, waived the need to obtain written informed consentfrom the participants. The final study group included 86 consecu-tive patients with a primary diagnosis of HCC in Child-Pugh classB liver function. According to the Child-Pugh numeric score, 42(48.8%) were scored as B7, 28 (32.6%) as B8 and 16 (18.6%) as B9.

2.2. Staging systems and treatment options

In our routine clinical practice, treatment options for CPT-Bpatients followed the BCLC staging system but were individualisedaccording to tumour extent, severity of the parameters contribut-ing to the Child-Pugh stage (and therefore the Child-Pugh numericscore), the presence of comorbidities and their severity, technicalapplicability of the treatment and individual consent for specifictreatments. In fact, the AASLD guidelines state that a “carefulselection of candidates for each treatment option and the expertapplication of these treatments are required to achieve the bestoutcomes” [6] and that recommendations are flexible and shouldbe implemented in a specific clinical setting [6].

2.3. Statistical analysis

Analysis of the data was carried out using SPSS statistical anal-ysis software v16 (SPSS Inc., Chicago, IL, USA). For continuousvariables, such as age and biochemical data, descriptive statisticswere calculated and reported as medians and ranges. Compar-isons among groups were carried out using non-parametric tests(Mann–Whitney and Wilcoxon). Categorical variables, includingCPT classification, BCLC classification, treatment strategy, ascites,encephalopathy, HCC aetiology, macroscopic vascular invasion,extrahepatic spread and portal hypertension, were described usingfrequency distributions.

The �2 test was used to detect differences in the BCLC and CPTgroups according to treatment strategy.

All tests were considered significant at P < 0.05.Survival curves were computed according to the Kaplan–Meier

method and were compared using Log rank tests. Analysis of thedata was carried out using SPSS statistical analysis software (SPSSInc., Chicago, IL, USA, 1999).

be much more suitable than ablation; the remaining patients 4.8%underwent TACE) (Table 3).

On the contrary, only 16/24 (66.7%) of the BCLC-A4 patients witha greater degree of liver dysfunction received curative treatment(10/15 patients in CPT-B8 and 6/9 in -B9) (Table 3). The remainingpatients received either TACE, 3/15 patients (20.0%) and 2/9 (22.2%)in CPT-B8 and -B9, respectively or only received palliative care 2/15(13.3%) and 1/9 (11.1%) in CPT-B8 and -B9, respectively.

3.2.2. Treatment of patients in the intermediate tumour stage(BCLC-B)

In our study, 59.3% of Child-Pugh B patients in BCLC-B stageunderwent curative treatment or TACE whereas the others wereincluded in research trials (3.7%) or received palliative care (37.0%).In detail, the frequency of CPT-B patients in the BCLC-B stage whounderwent curative treatment or TACE was 68.8% in Child-Pugh B7,50% in B8 and 0% in B9 (not statistically significant because of thelimited number of patients). Among patients in Child-Pugh B7 liverfunction, 11/16 (68.8%) underwent TACE (9/11, 81.8%) or curativetreatment (2/11, 18.2%) (Table 3). One patient was included in theresearch trial with Irinotecan because his large tumour burden pre-cluded TACE due to the high risk of liver decompensation [8]; theremaining four patients (25.0%) who were CPT-B7 were not con-sidered eligible for any tumour treatment and were managed withpalliative care. Among the patients who were CPT-B8, 5/10 under-went TACE and 5/10 received palliative care. The patient in CPT-B9liver function was managed with palliative care.

3.2.3. Treatment of patients in advanced and terminal tumourstages (BCLC-C/D)

For patients with advanced or terminal HCC (BCLC-C/D), noeffective treatment exists to date as the efficacy of Sorafenib hasonly been demonstrated in Child-Pugh A patients in the two regis-tration trials carried out in Western Countries or in the Asia Pacificregion [9,10]. We therefore examined the number of patients whoat least had the option of enrolment in HCC research trials in agree-ment with the guidelines for BCLC-C patients. These numbers arestrictly dependent on the types of trials available in each centre andtherefore no generalisation is postulated.

Despite the small numbers, the large majority of CPT-B7 patients(4/5, 80.0%) were enrolled in treatment studies. The percentagedecreased to 33.3% (1/3) in -B8 patients and to 16.7% (1/6) in -B9patients (not statistically significant because of the limited numberof patients).

3.3. Survival

After a median follow-up of 21.5 months (range 1 month to 9.2years), 76/86 patients (88.4%) died and 2 were lost to follow-up.The median overall survival of the entire study population was 21.0months (95% CI, 12.8–29.2), and the one- and three-year survivalrates were 60.7 and 25.0%, respectively. The long-term survivorsconsisted of the five patients who had received liver transplants(one died after 34 months). After the exclusion of these patientsfrom the analysis, the median survival decreased to 20.0 months(95% CI, 10.3–29.7), and the one- and three-year survival rates to58.2 and 21.5%, respectively. The median survival times in relationto the clinical and tumour characteristics are reported in Table 4.The analyses of prognosis showed tumour characteristics and somevariables of liver function (namely the presence of ascites andthe protrombin rate which contribute to the numeric Child-Pugh

decreased with progression of the BCLC stage (Tables 4 and 5),confirming in Child-Pugh B patients the already well-known rela-tionship between survival and the BCLC stage (P = 0.001).

In particular, TACE was found to be associ-ated with longer survival than palliative care (P = 0.049); however,the two groups were not totally comparable in terms of diseaseseverity, especially regarding the presence of ascites (42.9% in TACEpatients treated vs. 80% in best supportive care (BSC)) and serumcreatinine (0.99 vs. 1.25 mg/dl) (Table S1). A statistically significantdifference was reached, however, only for creatinine (probably dueto the small number of patients).

Univariate analysis was carried out to assess the role of clini-al variables regarding the eligibility of CPT-B patients for curativeherapy (percutaneous treatments) or TACE when in the BCLC-Btage. The variables analysed included age lower or greater than 68ears, prothrombin rate lower or greater than 66%, AFP lower orreater than 20 ng/dL, gender, presence or absence of ascites, pres-nce or absence of esophageal varices, single or multinodular HCC,iameter of the largest HCC lower or greater than 3 cm and bilirubin

. Discussion

The percentage of CPT-B patients in the different classes of theCLC differed on the basis of the severity of liver function impair-ent (namely Child-Pugh numeric scores -B7, -B8 and -B9) as

atients with worse liver function were more often associated with

The present study confirmed that field practice HCC treatment inpatients in the Child-Pugh B class closely adhered to the indicationsof the international guidelines [5,6] only in the early (BCLC-A4) andadvanced (BCLC-C/D) HCC stages.

Concerning CPT-B patients in the intermediate stage (BCLC-B),the assessment was more complicated since the guidelines [5,6,11]were discordant and without a specific recommendation for thetreatment of these patients. In our centre, only selected CPT-Bpatients in the BCLC-B stage usually undergo selective or super-selective TACE (which has limited impact on liver function [12]and better effectiveness). The choice is made after multidisciplinaryexamination and consideration of the tumour burden and clin-ical conditions. We do so [13] in agreement with the fact thatsome Child-Pugh B patients were present in a meta-analysis whichdemonstrated a survival benefit for TACE therapy in nonresectableHCC [14], representing up to 28% of the randomised patients inone study [15] and in agreement with the opinion of a group ofexperts, which included also some members from our centre [8].This approach was also recently endorsed by EASL which proposedTACE in Child-Pugh B7 patients in the BCLC-B stage [11]. The majorcontraindications for TACE treatment in our clinical practice werefrank jaundice, clinical encephalopathy, refractory ascites or hepa-torenal syndrome. In the present series of patients, approximatelyhalf of the BCLC-B patients in Child-Pugh B class (namely, 11/16in -B7 and 5/10 in -B8) underwent potentially effective treatment(almost always TACE) whereas the remaining patients were mainlyoffered only palliative care. This finding points out the problem ofestablishing the most appropriate treatment for CPT-B patients inthe BCLC-B stage since, in routine clinical practice, approximately

nivariate analysis was carried out. However, the only variablehich was statistically significant for the likelihood of receiv-

ng curative treatment or TACE was age <68 years. It should beoted that the sample size of patients was small and the analysisight be subject to potential statistical underpowering. However,

s reported in Table 3, there is a trend towards a higher rate of eli-ibility for receiving effective treatment in patients in CPT-B7 thann -B8 or -B9 suggesting that clinical variables may have a role inetermining eligibility for treatment.

As expected, the analysis of survival showed a progres-ive decrease in survival with progression of the BCLC stageTables 4 and 5). For instance, patients in the BCLC-B stage had

median survival of 8.0 months (95% CI, 5.5–10.5). In addition, theurvival subanalysis according to the CPT numeric score (Table 5)howed that CPT-B7 patients had a longer survival rate thanatients in CPT-B8 and -B9 (9.0 vs. 6.0 months, P = 0.048) despitehe fact that they were both in the same Child-Pugh class and wouldccordingly receive the same prognostic weight in all staging sys-ems [2–5]. That data confirmed the very important role not only ofhe tumour burden in HCC patients but also of the precise impair-

ent of liver function on survival. In fact, patients within BCLC-Btage have a different prognosis if in CPT-A or CPT-B stage liverunction but also if in CPT-B7 or -B8 or -B9.

These findings again stress the extensive variability of patientsithin the BCLC-B class who cannot be considered a homoge-eous group having a similar prognosis even within specific CPT-Blass liver function. Individual Child-Pugh B numeric scores mayontribute to refining prognosis, even though they do not seemufficient to subdivide patients in the Child-Pugh B class. This isot in disagreement with previous studies showing the role of liver

unction in patient prognosis and treatment allocation since thosetudies [2,5] considered only entire Child-Pugh classes and not theole of individual numeric scores.

Since this is a field practice and not a randomised study, it ismpossible to establish whether there was a detrimental effect ofACE in our BCLC-B patients (which was not in the study design).owever, the survival subanalysis, according to the Child-Pughumeric score of the BCLC-B patients undergoing TACE (Table 6),ends to suggest that, in CPT-B8 patients, the prognosis is so grimmedian survival of 6.0 months, range 1.1–10.9) that the likeli-ood of a benefit from TACE as an antitumour treatment is stronglyhallenged by the detrimental effects on liver function. However,n CPT-B7 patients, a consistent number achieved acceptable sur-ival after TACE (median survival of 22.0 months, range 0–60.0),omparable to those included in Llovet’s meta-analysis [15] whichas largely based on Child-Pugh A patients. That result seems to

e in agreement with the most recent published guidelines [11]hich recommend TACE in patients with well-compensated liver

unction, including CPT-B7 patients, and with a recent expert opin-on proposal for BCLC substaging, which also includes specific CPTcores [16]. It is worth noting that survival rates of BCLC-B patientsreated with TACE in our study, even CPT-B7 patients, had a skewedistribution (Table 6). This also suggested the great heterogeneityf this limited population (as found in the control arms of differentandomised trials [17]). Unfortunately, we were unable to iden-ify any clinical variables suggesting a better outcome (Table 6);his was probably a consequence of the limited number of patientshich makes the analysis more subject to potential statisticalnder-powering. Future research focusing on the identification ofhe most suitable patients for TACE within the CPT-B7 group areeeded.

Altogether, our current data are in keeping with those reported

Japan Society of Hepatology regarding the actual management ofHCC in Japan [19], further strengthening the opinion that this isa highly neglected problem in research trials as well in practiceguidelines and requires dedicated studies.

The main limits of the current study are represented by the rel-atively low number of patients and the retrospective observationaldesign (no prospective randomisation) which prevent the rigorousdefinition of variables capable of indicating or contraindicating spe-cific treatments, or the superiority of one treatment as comparedto another. In the absence of any randomised prospective studies inthis class of patients (CPT-B), the strengths of the study supportingthe conclusions are the consecutive series of cases (thanks to theworking methodology of our Centre) and the experienced multidis-ciplinary team management which optimises treatment allocation,as suggested by the guidelines.

In conclusion, the difficulty in making recommendations forChild-Pugh class B patients in the BCLC-B stage is understandablesince hardly any study on the treatment of HCC has specificallyfocused on this group; they are most often grouped together withChild-Pugh A patients. Since the latter usually constituted themajority of the study populations in randomised controlled trials[10,15,20], they usually dictated prognosis and treatment alloca-tion.

Our findings confirmed the need for specific separate researchregarding the segment of Child-Pugh B patients in the BCLC-Bstage.
