Role of pre-operative percutaneous embolization in orbital alveolar soft part sarcoma - An experience from a tertiary eye-care center.

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
purposeTo describe the clinic-radiological, pathological profile, and management outcomes of primary alveolar soft-part sarcoma (ASPS) of the orbit.
methodsA retrospective analysis of all histopathologically proven cases of orbital ASPS that presented between May 2016 and September 2019 was done. Data collected included demographics, clinical features, imaging characteristics, metastatic workup, management, and follow-up.
resultsFive patients, of which four were males, presented to us during the study period. The mean age of presentation was 12.6 years (range 3-22 years). The most common presenting features were abaxial proptosis (n = 4) and diminished vision (n = 4). Imaging showed a well-defined orbital mass in all patients with internal flow voids in three. Preoperative percutaneous embolization with cyanoacrylate glue was done in these three patients owing to high vascularity. Four patients underwent complete tumor excision. One patient underwent exenteration. Histopathology showed polygonal tumor cells arranged in a pseudo-alveolar pattern and Periodic Acid-Schiff (PAS) positive crystals in the cytoplasm in all patients. One patient had systemic metastasis at presentation and developed a local recurrence after 3 months. No recurrence or metastasis was noted in the remaining four patients at a mean final follow-up of 11.2 months (range 5-15 months).
conclusionASPS is a rare orbital neoplasm that poses a diagnostic and therapeutic challenge. Imaging might show a soft-tissue tumor with high vascularity. Multidisciplinary management with interventional radiologists for preoperative embolization of vascular lesions helps minimize intraoperative bleeding and aids in complete tumor resection. A localized orbital disease carries a better prognosis.
