A comparative analysis of hand sarcoma by anatomical site: A case series.
Article in Molecular and clinical oncology, 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
Hand sarcomas are very rare, and few studies have focused on their anatomical distribution, such as involvement of the fingers vs. the palm/dorsum (PD). The present study reviewed 24 cases of hand sarcomas identified from medical records of National Cancer Centre Hospital (Tokyo, Japan) between January 2010 and December 2022, examining sex, age, maximum tumour size, metastasis, histology, origin (bone vs. soft tissue), pain, biopsy performance, unplanned excision at previous institutes, treatment (surgery including reconstructive procedures, chemotherapy, and radiotherapy) and prognosis. The patients were divided into two groups, finger and PD, to facilitate comparison. Among the 24 cases, 9 occurred in the fingers and 15 occurred in the PD. Soft tissue was involved in 21 cases, while 3 cases arose from the bone, all in the fingers. Pain was present in 11 cases, with 6 cases (33%) in the fingers and 5 cases (66%) in the PD group. Synovial sarcoma, the most common histological subtype among the series, occurred exclusively in the PD group (n=7). In the finger group, 9 patients were managed with amputation, and only one received adjuvant therapy. In contrast, 10 of the 15 PD sarcomas underwent wide resection with reconstruction, and 6 received chemo- or radiotherapy. Overall, hand sarcomas had a favourable prognosis, with 86% overall survival and 77% disease-free survival rates; however, pleomorphic spindle cell sarcoma exhibited an exceptionally poor prognosis. In conclusion, synovial sarcoma was more prevalent in the PD region and finger sarcomas exhibited a slight tendency to cause pain. Treatment strategies varied significantly between the finger and PD groups.
