1 · What the graph read from it

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.

2 · The registry

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

objectivesTo evaluate the mid-term outcome of salvage radiofrequency ablation (RFA) treatment in patients who exhibited intrahepatic recurrence after major hepatectomy for colorectal liver metastases (CRCLM).

methodsObservational study on 23 consecutive patients (mean age 59 ± 9 years; 14/9 male/female) who, after a single (11/23) or multiple rounds (12/23) of major hepatic surgery, developed recurrent CRCLM in the liver remnant. Patients with a maximum of three metastases measuring up to 3 cm, and without relevant extrahepatic disease, underwent CT-guided RFA. Using the Kaplan-Meier-method, median intrahepatic progression-free-survival (ihPFS) and overall survival (OS) times after salvage RFA were compared with the same patients' time between the respective last round of surgery and diagnosis of intrahepatic recurrence leading to RFA.

resultsMedian follow-up was 26 months (range 12-103 months). Median ihPFS time after RFA was 8 months (range 1-81 months). Median ihPFS time after the respective last round of surgery and RFA in the same patients had been 5 months (range 1-23 months), thus yielding similar ihPFS times after surgery vs. after salvage RFA (p = 0.238; Mood's median test). After RFA, 15/23 (65%) of patients developed new hepatic metastases within the first year post-RFA. Median OS was 37 months, with a 1-year OS rate of 100%, 3-year OS rate of 57%, and 5-year OS rate of 24%. No major complications were observed.

conclusionsPatients who exhibit intrahepatic recurrence of CRCLM after major hepatectomy will experience intrahepatic recurrence after salvage RFA as well, and after similar time intervals. However, long-term ihPFS may still be achieved in some patients. KEY POINTS: • Patients who exhibit intrahepatic recurrence of colorectal liver metastases after major hepatectomy will experience intrahepatic recurrence after salvage RFA as well, and after similar time intervals. • About two-thirds of all patients develop new metastases elsewhere in the liver within 1 year after RFA. • However, long-term intrahepatic progression-free survival may still be achieved in some patients.
