A Case of Intraocular Metastasis of Lung Cancer Diagnosed Using Cell Block Preparation of the Vitreous Humor.
Article in Cancer diagnosis & prognosis. 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
BACKGROUND/
aimMasquerade syndrome is characterized by uveitis-like manifestations caused by tumor cell infiltration into the ocular tissues. The aim of the study was to report a lung cancer patient with persistent unilateral vitreous opacity, who was eventually diagnosed with masquerade syndrome using cell block preparation. CASE REPORT: An 82-year-old female complained of blurred vision in her left eye (OS). Because of pulmonary adenocarcinoma, she had previously received anticancer drug treatment at another Hospital and achieved partial remission. Ophthalmic examinations revealed anterior chamber inflammation and vitreous opacity OS. Corticosteroid eye drops were administered, but the inflammation did not improve, and was referred to the Hokkaido University Hospital. The left best-corrected visual acuity was 0.1 with normal intraocular pressure. Anterior chamber inflammation was 2+ cells, and vitreous haze was 4+ OS. B-mode ultrasonography showed diffuse heterogeneous high echoic changes in the vitreous cavity. She underwent vitrectomy, and cell block preparation of the vitreous infusion fluids was performed. Cytopathology revealed adenocarcinoma cells with a high nuclear/cytoplasmic ratio and glandular formation. The immunocytochemical study showed that tumor cells were positive for thyroid transcription factor-1 (TTF-1), napsin A, and CK7, therefore diagnosis of masquerade syndrome due to intraocular metastasis of pulmonary adenocarcinoma was reached. Chemoradiotherapy was administered, and the eye got phthisis bulbi after irradiation 2 years after diagnosis.
conclusionCell block preparation using vitreous humor may be useful in the diagnosis and management of intraocular metastasis of pulmonary adenocarcinoma in patients with prolonged vitreous opacity.
