Functional Outcomes of Limb Salvage Surgery in Patients with Giant Cell Tumor of Bone of the Lower Extremities: A Cross-sectional Comparative Study.

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
Background and Objectives: Giant cell tumor of bone (GCTB) is a benign aggressive tumor primarily treated with surgery. Neoadjuvant treatment with denosumab or zoledronic acid is a common adjunct given to down-stage tumors and facilitate limb sparing surgery. This study sought to determine the characteristics, outcomes, and occurrence of complications following resection (RS) or extended curettage (EC) for GCTB of the lower extremities. Correlation of neoadjuvant therapy with the occurrence of complications was also investigated. Methods: This is an analytical cross-sectional study of 30 patients diagnosed with GCTB of the lower extremity treated between 2015 to 2022 in a single tertiary hospital. Functional outcomes were determined using the 1993 version of the Musculoskeletal Tumor Society (MSTS) score. Mean follow-up for all patients was 2.6 years (SD 1.8). Twenty-two patients (73%) underwent resection, while eight (27%) patients underwent extended curettage. Of the 30 patients, 26 (87%) patients received neoadjuvant therapy, with 21 (81%) given denosumab and five (19%) given zoledronic acid. Results: Functional outcomes were excellent for 23 patients (77%), with no significant difference between RS and EC groups. Nine complications occurred in the RS group, including dehiscence (n=3), superficial infection (n=2), implant failure (n=1), nonunion (n=1), palsy (n=1), and implant irritation (n=1). Five complications occurred in the EC group, four of which were noted to be recurrences, with one case of deep infection. Recurrence was noted to be significantly higher ( Conclusions: Functional outcomes of EC and RS appear to be comparable, including the incidence of complications. However, recurrence was noted to be significantly higher in EC. There appears to be no clear advantage between denosumab or zoledronic acid for GCTB. As a neoadjuvant medication and/or to control tumor progression, zoledronic acid may be the more economic option especially for patients in developing countries.
