Summary
Resecting small hepatocellular carcinoma (HCC) significantly improves long-term survival. Early detection and surgical treatment of small HCC are crucial for better patient outcomes and survival rates.
Area of Science:
- Hepatobiliary Surgery
- Surgical Oncology
- Gastroenterology
Background:
- Hepatocellular carcinoma (HCC) remains a significant global health challenge.
- Treatment outcomes for HCC have historically varied, with a need for improved survival strategies.
Purpose of the Study:
- To compare the outcomes of surgical resection for small hepatocellular carcinoma (HCC) versus clinical HCC.
- To evaluate the impact of early detection and treatment on HCC survival rates over time.
Main Methods:
- A retrospective comparative study of 92 pathologically proven small HCC cases (≤5 cm) and 787 clinical HCC cases.
- Data collected from Zhongshan Hospital between 1958 and 1984, analyzing resection rates, operative mortality, and 5-year survival.
Main Results:
- Surgical resection of small HCC demonstrated a higher resection rate (85.9%) and a significantly better 5-year survival rate (70.3%) compared to clinical HCC (28.7% resection, 19.9% 5-year survival).
- The overall 5-year survival rate for HCC increased from 1.7% to 22.6% during the study period, correlating with an increased proportion of small HCC diagnoses.
- Reoperation for subclinical recurrence after small HCC resection improved 5-year survival from 56.2% to 70.3%.
Conclusions:
- Resection of small HCC is the optimal approach for achieving long-term survival.
- The study suggests a paradigm shift in understanding HCC's natural history, early development, and treatment strategies based on improved early detection and surgical intervention.
