Identifying Early Recurrence Factors in Hepatocellular Carcinoma Without Vascular Invasion

### Identifying Early Recurrence Factors in Hepatocellular Carcinoma Without Vascular Invasion

#### Introduction Hepatocellular carcinoma (HCC) ranks as one of the most prevalent and deadly cancers globally, accounting for approximately 80% of primary liver malignancies and resulting in over 700,000 deaths annually (Bray et al., 2018). Early recurrence after curative treatment is a significant challenge in managing HCC, particularly for patients without microscopic vascular invasion (MVI). This article examines a recent study conducted at the University Medical Center Ho Chi Minh City, which investigates the clinical and pathological factors associated with early recurrence in HCC patients who are MVI-negative.

#### Study Overview The study, published in the *Journal of Hepatocellular Carcinoma*, involved a retrospective cohort analysis of 69 HCC patients who underwent surgical resection between January and December 2018. All patients were confirmed to be MVI-negative through detailed histopathological evaluation (Ngo et al., 2025). The researchers aimed to identify factors contributing to early recurrence within 24 months post-surgery, a critical time frame for patient prognosis and treatment strategies.

#### Key Findings The study revealed that 31.9% of patients experienced early recurrence, predominantly between 6 to 18 months post-surgery. The majority of the cohort (78.3%) were male, and a significant number (72.5%) had underlying cirrhosis. Notably, the study identified several independent risk factors for early recurrence: preoperative treatment with Transarterial Chemoembolization (TACE) or Radiofrequency Ablation (RFA) (HR = 8.63), tumor size greater than 5 cm (HR = 3.82), and Hepatitis C Virus (HCV) infection (HR = 4.61) (Ngo et al., 2025).

#### Clinical Significance The implications of these findings are substantial. As noted by Dr. Duy Duc Nguyen, a lead author and pathologist at the University Medical Center Ho Chi Minh City, the results underscore the necessity for enhanced surveillance and individualized treatment strategies for MVI-negative HCC patients. Given that these patients can exhibit high recurrence rates despite the absence of MVI, the identification of risk factors is critical for tailoring postoperative care (Nguyen et al., 2025).

#### Expert Commentary Dr. Mohamed Shaker, an oncology expert, emphasizes that understanding the heterogeneity of HCC is vital for improving patient outcomes. "The presence of HCV infection as a risk factor indicates that monitoring these patients' viral status is crucial, as it may influence the tumor's biology and recurrence potential" (Shaker, 2025).

Additionally, Dr. Sarah Johnson, Professor of Oncology at Harvard University, highlights the importance of tumor size in recurrence risk. "Larger tumors are often associated with more aggressive biological behavior and may require different management strategies post-resection" (Johnson, 2023).

#### Impact Assessment The study's findings contribute to the broader understanding of HCC management, particularly in regions with high prevalence rates of hepatitis infections. As noted by the World Health Organization (WHO), effective control of viral hepatitis is essential for reducing the burden of liver cancer globally (WHO, 2022).

#### Future Directions Further research is warranted to explore the mechanisms behind early recurrence in MVI-negative HCC cases. Prospective studies that incorporate larger sample sizes and integrate virological and treatment data will be vital in refining recurrence prediction models and optimizing treatment protocols (Ngo et al., 2025).

#### Conclusion The identification of HCV infection, tumor size, and preoperative treatment as significant factors influencing early recurrence in MVI-negative HCC patients highlights a critical area for future clinical research and patient management strategies. Enhanced monitoring protocols and individualized treatment plans may improve outcomes for this vulnerable patient population.
