Percutaneous Cryoablation Under Local Anesthesia for Pulmonary Metastases From Colorectal Cancer: Long-Term Outcomes From a Single-Institution Retrospective Cohort.
Article in Cancer reports (Hoboken, N.J.), 2026. 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
backgroundSurgical resection is the standard treatment for pulmonary metastases from colorectal cancer, but its safety and long-term efficacy in medically inoperable patients remain limited. Percutaneous cryoablation is a minimally invasive alternative to surgical resection and has gained increasing attention in recent years.
aimsThis retrospective study aimed to evaluate complication rates, local tumor control, and overall survival associated with percutaneous cryoablation for pulmonary metastases from colorectal cancer. METHODS AND
resultsWe retrospectively reviewed patients treated with percutaneous cryoablation from 2002-2017. Complications were defined as adverse events ≥ grade 2 per Common Terminology Criteria for Adverse Events version 5.0. In total, 126 metastatic pulmonary tumors in 48 patients were treated across 73 sessions. Complications occurred in 18 sessions (24.7%), including 2 grade ≥ 3 events (2.7%). No treatment-related deaths occurred within 30 days. With a median follow-up of 9.7 months (maximum, 155.4 months), local tumor control rates at 1, 3, and 5 years were 74.5%, 58.8%, and 56.4%, respectively. Median overall survival was 3.8 years, with 1-, 3-, 5-, and 10-years rates of 86.8%, 60.4%, 41.9%, and 36.6%, respectively. The relatively short median follow-up should be considered when interpreting these long-term local control estimates. Six patients achieved 10-years survival.
conclusionPercutaneous cryoablation is a safe, minimally invasive option that provides favorable local tumor control and encouraging long-term survival outcomes.
