Lay summary: Early de compensated cirrhotic patients with
liver cancer have more option of treatment by TACE.
Introduction
Liver cancer is the sixth most common cancer worldwide and the
second most common cause of cancer-related death. More than 90% of
liver cancers are hepatocellular carcinoma (HCC).
1
Staging is currently
based on the Barcelona Clinic Liver Cancer (BCLC) staging system
which includes tumor burden, liver function, and patient performance
status. Treatments are stratifed according to the BCLC stages.

Tran
arterial chemo embolization (TACE) is a modality of choice for HCC
patients with BCLC stage B (intermediate stage). TACE can also
be applied in very early and early stage HCC when surgery or loco-
regional therapies are not eligible due to tumor location or medical
comorbidities.

TACE was initially proved to improve survival in HCC
by several studies; however, most of the patients in these studies were
in Child A.
4‒7
According to the guidelines, TACE is recommended for
Child A and highly selected Child B by the American Association for
the Study of Liver Disease,
1
for Child A by the European Association
for the Study of the Liver,
2
and Asian Pacifc Association for the Study
of the Liver.

Thailand guideline 2015 states that patients with Child
≥9 are an absolute contraindication for TACE.
In Thailand, most HCC patients often come with late presentation;
therefore, they tend to be in the intermediate to advanced stage
and have impaired liver function.
8‒12
From the experience in our
institution, TACE is sometimes applied to patients beyond the criteria
due to ineligibility of other loco-regional therapies and limited access
to sorafenib or liver transplantation. Some Child-Pugh B patients with
scores of 8 or 9 undergo TACE with questionable outcomes. Few
studies, so far, have clarifed the effect of high Child scores on the
outcome of TACE and the results are conficting. Therefore, we aimed
to study the outcomes of TACE in HCC patients in terms of overall
survival among different Child scores and to determine the predictors
for survival at a tertiary care hospital.
Materials and methods
A retrospective cohort study was conducted at Songklanagarind
Hospital, Prince of Songkla University, Thailand. We recruited
patients diagnosed with HCC (ICD10 code C22.0) from January 1,
2007 to December 31, 2016 from the hospital database. The inclusion
criteria were patients aged ≥18, frst diagnosed with HCC, underwent
TACE as monotherapy or combination therapy, and had at least 1 OPD

Abstract
Background: Transarterial chemo embolization (TACE) is recommended for
hepatocellular carcinoma (HCC) patients with well-preserved liver function. In
Thailand, TACE is occasionally performed in decompensated cirrhosis due to
limited resources. We compared overall survival by TACE in HCC patients with
decompensated cirrhosis to those with compensated cirrhosis.
Methods: A retrospective cohort study was conducted at a tertiary hospital. HCC
patients were recruited from January 1, 2007 to December 31, 2016 and divided into
3 groups by Child-Pugh scores A, B (7), and B (≥8). Overall survival was the primary
outcome. P<.05 was considered statistically significant.
Results: A total of 331 hepatocellular patients were included: Child A (66%), Child
B (7) (20%), and Child B (≥8) (14%). The mean (SD) follow-up time was 20(16)
months and the median survival times were 22, 13, and 12months in Child A, Child
B (7), and B (≥8), respectively (P<.001). In comparison between Child B (7) and
Child B (≥8), the overall survival rates did not reach statistical difference (P=.91).
The overall survival rate in a subgroup of patients with Child B (9) was the worst.
Predictors for survival were high serum albumin, tumor size<5cm, TACE frequency
>2, multimodality treatment, and absence of complications.
Conclusions: TACE can be performed in HCC patients with early de compensated
cirrhosis (Child-Pugh score 7–8) resulting in a 1-year survival close to that of Child
A. Regarding conflicting Child-Pugh score recommendation for TACE, our study
suggests that TACE can be performed in patients with Child score of up to B8.
