Factors predicting concurrent cholangiocarcinomas associated with hepatolithiasis

Area of Science:

• Hepatobiliary Medicine
• Surgical Oncology
• Gastroenterology

Background:

• Hepatolithiasis is a known risk factor for cholangiocarcinoma.
• Early detection of cholangiocarcinoma in patients with hepatolithiasis is challenging.
• Identifying predictive factors is crucial for timely diagnosis and intervention.

Purpose of the Study:

• To identify clinical characteristics that predict cholangiocarcinoma in patients with hepatolithiasis.
• To compare patients with hepatolithiasis and concurrent cholangiocarcinoma (group HC) against those with hepatolithiasis alone (group H).

Main Methods:

• Retrospective study comparing 40 patients in group HC with 73 patients in group H.
• Analysis of clinical characteristics including age, weight loss, serum markers, and hepatolithiasis location.
• Receiver Operating Characteristic (ROC) curve analysis for serum CEA levels.

Main Results:

• Group HC patients were older (56.7 vs 49.2 years) and experienced more weight loss (51.5% vs 5.5%).
• Elevated serum alkaline phosphatase (181 vs 426 IU/L) and higher prevalence of hepatolithiasis in the right or both lobes (72.5% vs 50.6%) were observed in group HC.
• Serum CEA cutoff of 4.2 ng/mL showed 67.6% sensitivity and 90.5% specificity for cholangiocarcinoma detection.

Conclusions:

• Cholangiocarcinoma should be suspected in hepatolithiasis patients over 40 with specific clinical indicators.
• Key predictive factors include long stone history, weight loss, elevated alkaline phosphatase, low albumin, CEA > 4.2 ng/mL, and involvement of the right or both liver lobes.
• These findings aid in early detection and management of cholangiocarcinoma in the context of hepatolithiasis.
