Clinicopathological features and departmental distribution of sarcoma patients: a single-center retrospective study.
Article in BMC cancer, 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
backgroundSarcomas are heterogeneous malignancies with high misdiagnosis and referral challenges. Limited real-world data on sarcoma subtype distribution, age-specific patterns, and departmental referral characteristics in Chinese populations hinders the optimization of clinical management strategies. This study aimed to analyze the clinicopathological features and departmental distribution of 295 sarcoma patients, subtype patterns, to optimize diagnostic and referral strategies.
methodsThis retrospective study enrolled 295 inpatients with pathologically confirmed sarcomas who underwent surgical resection at the First Affiliated Hospital of Anhui Medical University between September 2020 and November 2023. Demographic, clinical, and pathological data were extracted from electronic medical records and pathology databases. Statistical analyses were performed using IBM SPSS 20.0 and R 4.5.2, with Pearson’s chi-square test for categorical associations and one-way analysis of variance for age differences across subtypes.
resultsThe cohort had a median age of 56 years, with middle-aged and older adults (41-80 years) accounting for 75.9% of cases, and a male-to-female ratio of 1.27:1. Patients were admitted across 17 departments, with Orthopedic Oncology (41.0%), Urology (12.9%), and Plastic Surgery (10.8%) as the top three. Extremities (35.6%) were the most common tumor location. The top five pathological subtypes were unspecified sarcoma (24.7%), liposarcoma (16.9%), chondrosarcoma (15.3%), osteosarcoma (10.5%), and dermatofibrosarcoma protuberans (DFSP, 6.8%). Significant associations were identified between pathological subtypes and age (χ²=144.5, P<0.001), admitting department (χ²=370.6, P<0.001), tumor location (χ²=412.4, P<0.001), and gender (χ²=22.2, P=0.014). immunohistochemical findings included CD34 positivity in 82.4% of DFSP cases and S-100 positivity in 76.7% of liposarcoma cases.
conclusionsSarcoma subtypes show distinct clinical factor-specific patterns, informing optimized referrals and treatment.Tailored pathways and standardized pathological assessment can enhance diagnostic efficiency and treatment outcomes for Chinese sarcoma patients.
