Hepatocellular carcinoma (HCC) is a significant consequence of chronic liver disease, often presenting at advanced stages when treatment options are limited. An innovative approach to identify patients at risk of developing HCC has emerged from a large multicenter study involving over 2,300 individuals with advanced chronic liver disease. This newly developed risk stratification algorithm, referred to as PLEASE, utilizes six vital clinical parameters to classify patients into varying risk categories, ultimately aiming to refine screening processes and improve patient outcomes.
The PLEASE algorithm incorporates six distinct factors: a platelet count lower than 150 × 10^9/L, liver stiffness measurement (LSM) of 15 kPa or more, age over 50 years, male gender, a diagnosis of viral hepatitis (either controlled or uncontrolled), and the presence of steatotic liver diseases. Notably, the study found that patients designated as “high risk” under this classification exhibited a striking cumulative incidence of 15.6% for developing de novo HCC within a two-year timeline. In contrast, individuals categorized as “low risk” had only a 1.7% probability, illustrating a marked disparity that underscores the algorithm’s potential utility for clinical practice.
The identification of patients at higher risk for developing HCC allows for more tailored healthcare interventions, proposing that these individuals should undergo more frequent and thorough HCC screening. Conversely, those in the low-risk group may be safely transitioned to less frequent surveillance, optimizing resource allocation and potentially reducing healthcare costs.
Dr. Jonel Trebicka and his team, who conducted the study, have advocated for the implementation of this algorithm in routine clinical settings. They emphasize that the parameters included in the PLEASE algorithm are routinely measured or easily obtainable in both inpatient and outpatient environments, facilitating its incorporation into existing healthcare protocols. This ease of application can lead to a significant shift in the existing paradigms of HCC screening, particularly in populations susceptible to liver dysfunction.
The editorial commentary accompanying the study by Dr. Stephen L. Chan of the Chinese University of Hong Kong provided vital insights, emphasizing the relevance of adopting risk-based screening programs. Many cancer screening initiatives have successfully implemented such models, resulting in improved patient outcomes and cost-efficiency. By leveraging the PLEASE algorithm to stratify patients based on risk levels, healthcare providers can better manage resources and focus their efforts on those who would benefit most from intensive surveillance.
While the inception of the PLEASE algorithm marks a significant advance in the early detection of HCC, it must be accompanied by enhanced adherence to surveillance protocols. Alarmingly, a U.S.-based multicohort study revealed that only 14% of patients received the recommended semi-annual screening for HCC. Moreover, a staggering two-thirds of patients failed to undergo any form of surveillance before their diagnosis of HCC. These figures reveal an urgent need for strategies that not only improve screening adherence but also raise awareness about the vital importance of regular HCC monitoring among at-risk populations.
Chan and colleagues have rightly pointed out that designing risk-based surveillance programs necessitates incorporating patient education and engagement strategies to foster commitment to follow-up care. Without addressing these adherence challenges, the benefits offered by the PLEASE algorithm may not be realized in practice, depriving at-risk individuals of essential early detection opportunities.
The development of the PLEASE algorithm brings forth a promising avenue for stratifying patients with chronic liver disease based on their risk for developing hepatocellular carcinoma. By identifying high-risk patients and improving screening frequency, healthcare professionals can enhance disease management and ultimately improve patient outcomes. However, the success of this initiative hinges on overcoming the challenges associated with adherence to surveillance protocols. Effective implementation will require a multifaceted approach that combines accurate risk assessment with ongoing patient engagement, paving the way for a future marked by improved surveillance practices and better prognoses for individuals at risk of HCC.
