Alpha-fetoprotein-producing adenocarcinoma in which the metastatic route was determined from calcified lesions.

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
Alpha-fetoprotein (AFP)-producing adenocarcinoma is known for its rapid progression and poor prognosis, and chemotherapy regimens are yet to be standardized. Here we describe the first report of AFP-producing adenocarcinoma with calcification. The metastatic route was visualized from the calcification, and combination chemotherapy was performed. A 77-year-old Japanese man was transferred to our hospital for treatment of liver tumors. Computed tomography (CT) revealed multiple liver tumors with portal vein tumor thrombosis. The tumors were highly attenuated before enhancement, suggesting various degrees of calcification. Serum levels of carcinoembryonic antigen (CEA), AFP, and the proportion of fucosylated AFP were considerably elevated. Gastroduodenoscopy revealed an elevated tumor occupying the duodenal bulb with an ulcerative lesion in the vicinity of the gastroduodenal junction, and biopsy specimens from the duodenum and liver revealed medullary adenocarcinoma with calcification. Three-dimensional reconstruction of CT images clearly showed that the calcified lesions had spread from the gastroduodenal junction to the liver via a route comprising the corresponding local vein, the superior mesenteric vein, and portal vein. The patient was accordingly diagnosed with calcified AFP-producing adenocarcinoma with multiple liver metastases. Combination chemotherapy using TS-1 and cisplatin (CDDP) resulted in a striking response for the initial 4 months in terms of tumor markers and CT findings. This is the first report of AFP-producing adenocarcinoma with calcification. A metastatic route from the primary tumor to the liver was clearly visualized by tracing the calcified lesions. Combination chemotherapy based on 5-fluorouracil and CDDP may have the potential to prolong survival.
