Primary Chest Wall Ewing Sarcoma With Diaphragmatic Invasion in an Adult: En-Bloc Resection and Polypropylene Mesh Reconstruction.
Article in Clinical case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Chest-wall Ewing sarcoma (CWES) is uncommon in adults and often abuts vital thoracic structures, making R0 resection challenging despite gains with multimodal therapy. A 46-year-old Arab male presented with year-long right-sided chest pain, weight loss, and a firm mass over the lower right ribs. CXR showed a lateral pleural-based opacity; computed tomography (CT) demonstrated a chest-wall lesion involving right ribs 9-11 with diaphragmatic contact. CT-guided core biopsy confirmed Ewing sarcoma. After 4 cycles of neoadjuvant multi-agent chemotherapy, he underwent composite resection of ribs 9-11 with partial diaphragmatic excision and polypropylene (Prolene) mesh reconstruction stabilized by two wires. Pathology revealed a small round blue cell tumor with broad necrosis; margins were negative laterally, posteriorly, and at cartilaginous/diaphragmatic edges, but the anterior margin was positive (R1). IHC showed diffuse membranous CD99, nuclear FLI1, diffuse vimentin, and focal NSE; molecular confirmation of EWSR1 rearrangement was recommended. This adult CWES with diaphragmatic invasion illustrates the need for multimodal care: induction chemotherapy to address micrometastases and facilitate resection, followed by aggressive local surgery and prosthetic reconstruction. The R1 anterior margin justifies adjuvant systemic therapy with consideration of postoperative radiotherapy to optimize local control. Definitive diagnosis relies on integrated histology, immunophenotype, and molecular testing. Adult CWES may require combined rib and diaphragmatic resection with prosthetic repair. Margin-negative surgery remains pivotal; when margins are positive, tailored adjuvant therapy is essential to mitigate local and micrometastatic risks.
