Redefining radiologic responses in high-risk soft-tissue sarcomas treated with neoadjuvant chemotherapy: final results of ISG-STS 1001, a randomized clinical trial.
Trial report in ESMO open, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundWe report the results of the pre-planned secondary analysis of radiologic responses (RRs) of ISG-STS 1001, a randomized trial comparing anthracycline + ifosfamide (AI) versus histology-tailored (HT) neoadjuvant chemotherapy for primary localized high-risk soft-tissue sarcomas of the extremities and trunk wall. PATIENTS AND
methodsPatients with undifferentiated pleomorphic sarcoma (UPS), leiomyosarcoma (LMS), malignant peripheral nerve sheath tumor, synovial sarcoma or myxoid liposarcoma (MLPS) were randomized, whereas patients with myxofibrosarcoma, pleomorphic liposarcoma, pleomorphic rhabdomyosarcoma or unclassified sarcoma were included in the observational arm (O) and treated with AI. Patients with UPS, LMS or MLPS needing concurrent preoperative radiotherapy were included in O. We evaluated associations between: disease-free survival (DFS)/overall survival (OS) and centrally reviewed RR, assessed with RECIST 1.1 and as percent dimensional variation (D; both dichotomized and continuous); DFS/OS and histology; RR and histology.
resultsFour hundred and thirty-five patients were included (287 randomized, 148 observed). The analysis of RRs comprised 236 patients (154 randomized, 82 observed) with measurable disease and available for central review. RECIST best responses were: 28 (11.9%) partial response (PR), 195 (82.6%) stable disease (SD), 13 (5.5%) progressive disease (PD). RECIST significantly correlated with DFS [PD versus PR: hazard ratio (HR) 8.18, 95% confidence interval (CI) 2.96-22.58; SD versus PR: HR 2.96, 95% CI 1.30-6.75] and OS (PD versus PR: HR 12.61, 95% CI 3.40-46.84; SD versus PR: HR 4.24, 95% CI 1.34-13.47). The median value of D was -1.6%. Patients with D >-1.6% had worse clinical outcomes than those with D <-1.6% (DFS: HR 1.73, 95% CI 1.19-2.50; OS: HR 1.86, 95% CI 1.21-2.86). D in continuous scale inversely correlated with DFS (HR 1.53, 95% CI 1.25-1.87) and OS (HR 1.78, 95% CI 1.41-2.25).
conclusionsThese results confirm the prognostic value of RRs as per RECIST and D and demonstrate that any variation in size predicts the proportional efficacy of treatment.
