Microwave ablation combined with curettage for low-grade chondrosarcomas in the extremities: a single-center study.
Article in BMC musculoskeletal disorders, 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
backgroundThe surgical treatment of low-grade chondrosarcoma in the extremities remains a topic of controversy. This study aims to evaluate the clinical efficacy of microwave ablation combined with curettage in treating low-grade chondrosarcoma of the limbs.
methodsWe analyzed data from 17 patients who underwent microwave ablation for low-grade chondrosarcoma of the extremities over the past decade. Results were assessed based on general condition, surgical complications, local disease control, and functional outcomes as measured by the Musculoskeletal Tumor Society (MSTS) 93 scoring system.
resultsAmong the 17 cases of low-grade chondrosarcoma, the distribution included 8 in the humerus, 7 in the femur, and 2 in the fibula. The median maximum diameter of the tumors was 5.5 cm (range: 4.0-8.2 cm), with a median follow-up of 53 months (range: 19-128 months). No patients required blood transfusions or experienced perioperative complications. The median surgical duration was 130 min (range: 60-150 min), and the average hospital stay was 7.9 days (range: 6-11 days). No local tumor recurrence or distant metastasis was observed during follow-up. Most patients reported minimal postoperative impact on limb functionality, with a median MSTS score of 28 (range: 20-30). Two patients sustained fractures; one underwent secondary internal fixation surgery and healed, while the other, with an asymptomatic microfracture, was monitored conservatively.
conclusionsMicrowave ablation combined with curettage is a viable option for local control in the treatment of low-grade chondrosarcoma in the extremities.
