Mass-forming intrahepatic cholangiocarcinoma: treatment outcomes after curative-intent resection in an Australian tertiary referral hospital.
Article in ANZ journal of surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundMass-forming intrahepatic cholangiocarcinoma (MF-ICC) is the second most common primary liver cancer and liver resection offers the best chance of possible cure. This study aimed to assess treatment outcomes and prognostic factors for long-term survival in patients who underwent curative-intent liver resection.
methodsA retrospective analysis was conducted on prospectively collected data from patients with MF-ICC managed at the Royal North Shore/North Shore Private Hospital from January 1998 to October 2023. Baseline, peri-operative and long-term outcomes have been analysed, including an overall survival (OS) and disease-free survival (DFS) analysis.
resultsDuring the 25-year study period, 47 patients underwent curative-intent liver resection for primary MF-ICC at a median age of 70 years. The median OS was 36 months, with a 5-year OS of 33%. Multiple liver tumours (HR = 2.84; 95% CI = 1.24-6.48; P = 0.013) and a positive resection margin (HR = 2.46; 95% CI = 1.10-5.52; P = 0.029) were identified as independent predictors of poor long-term OS. Recurrence occurred in 62% of patients after a median DFS of 16 months, with poor tumour differentiation (HR = 3.93; 95% CI = 1.62-9.54; P = 0.002) and elevated tumour markers (HR = 3.47; 95% CI = 1.53-7.87; P = 0.003) as independent predictors of poor DFS.
conclusionLiver resection can offer a significant chance for prolonged survival in a highly selected population of patients with MF-ICC. However, the surgical challenges inherent in treating this rare disease are evident, emphasizing the need for a multimodal approach and continued exploration of additional therapies to enhance personalized treatment strategies.
