Locoregional options in the management of cholangiocarcinoma: single center experience
Bibliographic record
Abstract
BACKGROUND: The purpose of this case series is to assess the safety and efficacy, as well as the overall survival (OS) and progression free survival (PFS) of patients with intrahepatic cholangiocarcinoma (ICC) treated with percutaneous ablation, transarterial arterial chemoembolization (TACE) or a combination of both at our institution. METHODS: Ten patients with pathological diagnosis of adenocarcinoma treated at out institution between January 1st 2013 and January 1st 2019 were reviewed. Three patients received a combined TACE and ablation treatment, three patients received TACE without ablation and four patients were treated with ablation only. Ablation technical success was determined by absence of residual tumor in the ablation zone on follow-up imaging one-month post-ablation. TACE response was assessed using the Modified Response Evaluation Criteria in Solid Tumors (mRECIST). Technical success was defined as injection of chemoembolic material in the involved liver lobes. PFS and OS were calculated from the date of diagnosis. RESULTS: In the TACE and radiofrequency ablation (RFA) group, OS was 12, 55 and 56 months; PFS was 5, 6 and 32 months, one patient died and two others remain alive. In the TACE group, OS was 29, 10 and 5 months; PFS was 15, 10 and 4 months. All three patients remain alive. In the ablation group, OS and PFS were 16, 31, 30 and 40 months. All patients remain alive. Overall, 9 of 10 patients are alive, with a Median OS and PFS of 29.5 and 15.5 months, respectively, with some patients remain alive over four years following initial presentation. CONCLUSIONS: Our study shows that ablation and TACE in combination with more traditional modalities such as chemoradiation and surgical resection can extend survival in patients with ICC significantly. Locoregional therapy is well tolerated with only minor adverse events. The use of stereotactic body radiation therapy (SBRT) with ablation demonstrated the synergistic nature of using multiple lines of interventions.

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.
