| Abstract|| |
This document aims to assist oncologists in making clinical decisions encountered while managing their patients with hepatocellular carcinoma (HCC), specific to Indian practice, based on consensus among experts. Most patients are staged by Barcelona Clinic Liver Cancer (BCLC) staging system which comprises patient performance status, Child-Pugh status, number and size of nodules, portal vein invasion and metastasis. Patients should receive multidisciplinary care. Surgical resection and transplant forms the mainstay of curative treatment. Ablative techniques are used for small tumours (<3 cm) in patients who are not candidates for surgical resection (Child B and C). Patients with advanced (HCC should be assessed on an individual basis to determine whether targeted therapy, interventional radiology procedures or best supportive care should be provided. In advanced HCC, immunotherapy, newer targeted therapies and modern radiation therapy have shown promising results. Patients should be offered regular surveillance after completion of curative resection or treatment of advanced disease.

There are several international guidelines pertaining to hepatocellular carcinoma (HCC),, but none have been issued by the Indian Council of Medical Research specific for the Indian setting. The Indian population requires a unique understanding of the incidence and biology of the disease, with a different socio-economic spectrum and accessibility to healthcare resources. These guidelines are aimed to maximize healthcare resources, standardize diagnosis methodology and strengthen the multidisciplinary approach regarding the treatment of HCC in India.
| Incidence and risk factors|| |
Globally, HCC is the fifth most common cancer (0.90 million new cases per year) and is the third leading cause of annual deaths due to cancer (0.83 million deaths per year),. There is a lack of nationally representative data, so we must depend on autopsy studies, national cancer registries and population-based surveillance data to estimate the frequency of HCC in India. A large-scale verbal autopsy study in 2010 reported liver cancer to be the fourth leading cause of cancer-related deaths in men (14,000 deaths), with an age-standardized mortality rate (ASMR) of 6.8/100,000 population. In women, liver cancer was the eighth most common cause of cancer-related deaths (12,000 deaths), with an ASMR of 5.1/100,000 population. The areas covered by Naharlagun population-based cancer registry (PBCR) reported the highest age-adjusted incidence rate (AAIR) of 38.0 in Papum Pare district in Arunachal Pradesh.
Risk factors corroborated in Indian studies are cirrhosis, hepatitis B infection, hepatitis C infection, alcohol consumption, aflatoxin exposure, smoking, diabetes, non-alcoholic fatty liver disease and age,. Among cancers as a whole, HCC is particularly amenable to prevention given a detailed understanding of risk factors. The most feasible and cost-effective strategy in the Indian scenario appears to be primary prevention. The most easily applicable modality is the hepatitis B vaccination, which is recommended in newborns and healthcare workers. For patients with a high viral load in HBV cirrhosis, antiviral therapy assists in preventing HCC development and is, therefore, recommended. Patients at risk of developing HCC are candidates for regular surveillance if they are eligible for HCC treatment. The recommended surveillance test is a six-monthly ultrasound abdomen by an experienced radiologist.
| Diagnosis and staging|| |
Non-invasive diagnosis can be established by demonstration of the typical HCC radiological hallmark (hyperenhancement on arterial phase and wash out on porto-venous phase) by one of the imaging techniques in nodules >2 cm and by two coincidental techniques with nodules of 1-2 cm in diameter [dynamic computed tomography (CT) or dynamic magnetic resonance imaging (MRI)]. If a suspicious nodule measuring >1 cm fails to show typical enhancement pattern on both dynamic CT and dynamic MRI, image-guided sampling is indicated. The 2017 version of the Liver Imaging Reporting and Data System (LI-RADS) is a useful comprehensive system which incorporates features such as arterial-phase hyperenhancement, observation size, wash out, enhancing capsule and threshold growth. The CT/MRI LI-RADS requires a CT/MRI with extracellular agents or MRI with hepatobiliary agents.
Immunohistochemical markers useful for diagnosing HCC include glypican-3, glutamine synthase, arginase 1, HepPar1, alpha foetoprotein (AFP) and heat shock protein-70.
Small nodules (<1 cm) in cirrhotic livers should be subjected to a 3-6-monthly follow up using the same technique, which detected the nodule, for a period of two years. Evaluation by gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA) - enhanced MRI scan, or a SonoVue contrast-enhanced ultrasound, is an alternative strategy. Gadobenate dimeglumine MRI is also available in India and is particularly useful for lesions not displaying the characteristic radiological features of HCC as well for detecting high-grade dysplastic nodules. A PET (positron emission tomography) scan is not routinely recommended. AFP estimation is no longer part of the diagnostic algorithm of HCC.
In India, the BCLC (Barcelona Clinic Liver Cancer) staging system is commonly used and includes patient performance, Child-Pugh status, number and size of nodules, portal vein invasion and metastasis, and is most commonly used for prognostic information and treatment allocation. Stage 0 is very early, stage A is early, stage B intermediate, stage C advanced and stage D is terminal stage HCC.
| Multidisciplinary treatment for early disease|| |
All new cases should be discussed at the tumour board or in multidisciplinary team meetings, and the treatment strategy should be confirmed. Surgery (resection/transplant) forms the mainstay of definitive treatment. Surgical resection is advocated only in early-stage disease in patients with preserved liver function (Child-Pugh A) without evidence of portal hypertension or vascular invasion. Resection can be anatomical versus non-anatomical and open versus laparoscopic. In patients with decompensated liver disease or portal hypertension, liver transplant (from a living donor or cadaveric) is the treatment of choice as it not only treats the tumour but also the underlying predisposing liver pathology,.
Small tumours (<3 cm) in patients who are not candidates for surgical resection (Child B) can be offered ablative techniques. The percutaneous ablative therapies have role in the very early (BCLC-0) and early stage (BCLC-A), while the transarterial therapies are (generally) indicated in the intermediate stage (BCLC-B, C) of HCC. Radiofrequency ablation (RFA) is indicated when the lesion in not suitable for resection, the size of the lesion is up to 3 cm and number of lesions are three or less. The BCLC guidelines also support the use of image-guided ablation in very early HCC, which conforms to the criteria and for patients on waiting list for transplant.
Transarterial chemoembolization (TACE) is usually offered as palliative treatment; however, it also has a role as a bridge to transplant in the patients who are on the waiting list. This is a minimally invasive modality of treatment which has shown definitive survival benefits, especially in those who can be categorized as intermediate BCLC B patients. In the presence of portal vein thrombosis, transarterial radioembolization (TARE) in usually preferred. Various forms of radiation therapy have also been used with promising results in small tumours as well as a bridge to transplantation.
| Multidisciplinary treatment for advanced disease|| |
Unfortunately, most patients present with advanced disease, not amenable to curative treatment. Several Phase II studies have shown benefit of image-guided radiotherapy in local control and overall survival (OS) for patients with locally advanced HCC unsuitable for standard locoregional therapies,. Three-dimensional conformal radiotherapy (3D-CRT), intensity-modulated radiation therapy (IMRT) and stereotactic body radiotherapy (SBRT) make high-dose radiation to HCC possible with sparing of the surrounding non-tumour liver parenchyma. External beam radiation therapy (EBRT) in these various forms has also been shown to increase the chances of performing a TACE. EBRT has been reported to reduce tumour size, decrease pain and also improve survival in certain studies. It has also been used as an adjunctive therapy after resection or TACE with survival benefit,,.
In the absence of trials showing a distinct benefit, the use of systemic chemotherapy in the management of HCC is not recommended outside of clinical trials. Systemic chemotherapy may be an option for patients who progress on sorafenib and are in good physical health (BCLC stage C).
In the recent past, the only drugs with proven survival benefit were sorafenib and regorafenib in the first- and second-line therapy, respectively,. The landscape for the treatment of advanced HCC is rapidly changing with emerging newer therapies. Atezolizumab and bevacizumab combination resulted in better OS and PFS (progression-free survical) compared to sorafenib in first-line setting and has changed practice. Immune checkpoint inhibitors (CPI) offer promise, and the stage seems set for CPIs to become the mainstay of treatment for advanced HCC and may be also in the adjuvant setting,,. However, pembrolizumab Phase 3 trial in HCC in second-line setting did not meet its primary end point (OS and PFS). Sorafenib and lenvatinib have been demonstrated to be equally effective as a first-line therapy,. Regorafenib, cabozantinib (for sorafenib-intolerant patients) and ramucirumab have shown an OS benefit in the second-line. Supportive care involves providing support at all stages of a person's experience with cancer. Systemic therapies and their benefits are concisely shown in the [Table 1],,,,,,. This includes treatment of any underlying hepatitis, pain management, nutrition build-up, management of ascites, bleeding control and psychological support. Treatment algorithm is shown in the [Figure 1].

The follow up of patients is recommended every three months with monitoring of AFP levels and imaging to check whether there are signs/symptoms of progression.
The following are the brief indications for various modalities for the management of HCC (to be decided after multidisciplinary consensus):
- ( i) Liver resection: Non-cirrhotic/Child A with no or mild portal hypertension, resectable tumour with adequate FLR, BCLC A/B
- ( ii) Liver transplantation: Cirrhosis (any Child score) with or without portal hypertension, BCLC A/B, fitting into liver transplantation criteria
- ( iii) RFA: Up to 3 cm tumours, poor-risk surgical patients
- ( iv) TACE: No portal venous thrombosis, BCLC B, Child A/B, outside liver transplantation criteria
- ( v) TARE: BCLC B, Child A/B, with portal venous thrombosis
- ( vi) Targeted therapy: BCLC C, Child A/B
- ( vii) Best supportive care: BCLC D (poor performance status, Child C)
