Coronary angiogenesis in small-cell lung carcinoma: embolization of a left circumflex artery feeding vessel to a lung tumor and concurrent coronary revascularization.
Article in BMC cardiovascular disorders, 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
backgroundSmall-cell lung carcinoma (SCLC) can exhibit exuberant angiogenesis, but direct arterial feeders arising from coronary vessels are exceedingly rare. We report a case of a LCX coronary artery supplying a lung tumor, successfully managed with coil embolization. CASE PRESENTATION: A 64-year-old man with SCLC presented with a 7 × 8 cm left hilar mass, dyspnea, pleuritic chest pain, hoarseness, and 18 kg weight loss. Two months after starting chemotherapy, he developed an inferior STEMI. Angiography showed proximal LAD ectasia with an atherosclerotic stenosis, total RCA occlusion (culprit lesion), and ectatic LCX branches perfusing the tumor. The RCA STEMI was addressed first with emergent revascularization, followed by PCI of the LAD and embolization of the tumor-feeding artery. Fractional flow reserve was not assessed, and aspiration thrombectomy was not performed. The LCX feeder was embolized using detachable, fiber-coated platinum microcoils delivered through a microcatheter. Post-embolization angiography confirmed complete occlusion without complications. Two-month follow-up CT demonstrated tumor regression to 4.5 × 4 cm and marked relief of dyspnea, chest pain, and hoarseness. No tissue was available to exclude microscopic tumor emboli, but angiographic features favored plaque-rupture thrombosis rather than malignant embolization.
conclusionThis case underscores the importance of recognizing coronary feeding arteries in lung cancer and illustrates a multidisciplinary strategy-sequential PCI and targeted embolization-that achieved both oncologic (tumor devascularization and shrinkage) and cardiac (symptom control, revascularization) goals.
