Simultaneous multiple primary malignancies diagnosed by endoscopic ultrasound-guided fine-needle aspiration: A case report.
Article in World journal of clinical cases, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundMultiple primary malignancies (MPMs) refer to more than one primary malignancy in the same or separate organs of the same patient, and MPMs are considered when different histological characteristics are detected in epidemiological studies. Herein, we report a case presumed to be primary pancreatic cancer with multiple liver metastases by positron-emission tomography/computed tomography (PET/CT) and confirmed to be synchronous liver and pancreatic MPMs by endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). CASE SUMMARY: A 50-year-old man was referred to our hospital due to abdominal discomfort for 2 mo. Abdominal CT at a local hospital revealed a pancreatic mass with multiple liver nodules. After being transferred to our hospital, PET/CT confirmed all these lesions to have elevated metabolic activity, and therefore primary pancreatic cancer with multiple liver metastases was considered. EUS-guided liver aspiration unexpectedly found signet-ring cells with a high Ki-67 positive rate (20%), while EUS-guided pancreatic aspiration detected pancreatic neuroendocrine cells with a relatively low Ki-67 positive rate (1%). The final diagnosis from the multidisciplinary team was simultaneous liver and pancreatic MPMs. The patient returned to his local hospital for neoadjuvant chemotherapy and surgery, and he is still alive during the 6-mo postoperative follow-up.
conclusionAlthough rare, MPMs should be considered when treating pancreatic mass with suspected metastatic lesions, and EUS-FNA has proved minimally invasive and accurate.
