1 · What the graph read from it

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.

2 · The registry

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: Intrathoracic soft tissue sarcomas are rare and heterogenous tumors with limited data guiding their management. Due to anatomical complexity and delayed diagnosis, treatment can be challenging. This study aimed to assess clinical outcomes and prognostic factors in intrathoracic soft tissue sarcoma patients treated at a high-volume referral sarcoma center. Methods: This bi-institutional retrospective cohort study (2007-2022) analyzed patients with histopathologically confirmed intrathoracic soft tissue sarcomas. Data from two prospective registries were used to assess overall survival (OS), local recurrence (LR), and distant metastasis (DM) via Kaplan-Meier, cumulative incidence, and multivariable Cox regression. Results: Among 49 patients (median age: 56 years, 55.1% male), 40 (81.6%) had localized and 9 (18.4%) had metastatic disease at diagnosis. The median follow-up was 15.6 months. The median OS was 37.1 months for localized, 5.9 months for metastatic cases. Among localized cases, 55% had recurrences, evenly split between local and distant. LR incidence was 39.4% at 12 months, 53.7% at 24 months; DM incidence was 38.8% and 53.4%. OS was worse in patients >65 years [hazard ratio (HR): 2.69, P=0.04] and with metastatic disease (HR: 4.84, P=0.02). DM risk was higher in grade 2 (HR: 19.38, P=0.03) and grade 3 tumors (HR: 12.65, P=0.02) and those in the lungs, pleura, or diaphragm (HR: 3.56, P=0.046). LR was not associated with grade, margin status, or perioperative therapy. Treatment modality had no impact on DM. Conclusions: Despite a small sample, this is the largest clinical cohort on intrathoracic soft tissue sarcomas, which carry high local and distant recurrence risks. Worse outcomes were linked to age >65 years, metastatic presentation, higher grade, and lung, pleura, or diaphragm location. Given their rarity, multi-institutional studies are needed to refine risk factors, treatment, and outcomes.
