Surgery for Multifocal Intrahepatic Cholangiocarcinoma
Bibliographic record
Abstract
INTRODUCTION: Multifocal intrahepatic cholangiocarcinoma (m-iCCA) is a complex and aggressive form of primary liver cancer, often associated with poor outcomes. Although surgical resection is considered the only curative treatment for intrahepatic cholangiocarcinoma (iCCA), multifocality is frequently regarded as a contraindication due to the high risk of recurrence and limited survival benefits. Advances in surgical techniques and evolving treatment strategies have reopened discussions about the feasibility of resection in these cases. METHODS: We conducted this systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. A study protocol for the review was registered in the International Prospective Register of Systematic Reviews database. We systematically searched PubMed, Web of Science, MEDLINE, and ScienceDirect databases up to July 30, 2024, for studies analyzing surgical treatment outcomes for m-iCCA. We assessed the quality of the included studies according to the Newcastle-Ottawa Scale (NOS). RESULTS: After our initial search, 2,482 articles were found related to this topic and 381 articles were left for screening. We checked each article against the eligibility criteria and selected for the full-text analysis. Ten articles with 2,392 patients who had m-iCCA were included in our review. The reviewed studies reported extensive surgical procedures, such as extended hemihepatectomy and associating liver partition and portal vein ligation for staged hepatectomy, with median survival ranging from 18.9 to 27 months. Recurrence rates were higher in m-iCCA patients (67.8-74.3%) compared to solitary iCCA cases (52.4-60.5%), with recurrence-free survival as short as 4.5 months. Adjuvant chemotherapy was frequently used, although its effectiveness in terms of survival was inconsistent. One study reported a 5-year survival rate of 12.9% for surgical patients compared to 0% for non-operated patients. Survival outcomes were influenced by adverse prognostic indicators such as lymph node metastases and perineural invasion. CONCLUSION: Surgical resection for m-iCCA, while associated with high recurrence rates (67.8-74.3%), provides a survival advantage over nonsurgical management (median overall survival: 18.9-27 months vs. 8 months; 5-year survival: 12.9% vs. 0%) for carefully selected patients. More studies are needed to improve patient selection and refine treatment approaches to enhance long-term outcomes.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
